摘要： An elevator control system using vertically elongated single-turn loops of wire movable with the car past a vertical column of stationary coils of wire, one at each floor, which are de-energized one at a time repetitively at high speed. The sudden collapse of magnetic flux from a coil induces a pulse into the loops if the car is adjacent. Each loop has one or more twists so that the polarities of the induced pulses vary in a predictable manner over the vertical length of the loops. When pulses are induced in the loops, the unique combination of positive and negative pulses defines the quantized distance between the car floor and the building floor whose coil caused the pulses. The quantized distance between the car floor and any desired target floor in the building is computed repetitively by adding the pertinent floor heights, as stored in a memory, to the reading obtained from the loops.

摘要： A system for producing a velocity pattern for a vehicle such as an elevator car which must be brought smoothly to a stop accurately aligned with a desired one of a number of stations. The distance between the vehicle and the station at which a stop is required (target distance) is expressed in digital form, and is processed electronically to produce a velocity pattern which results in constant deceleration of the vehicle during the entire approach except for an initial build-up to, and a final tapering off from, the constant deceleration. A single adjustment for deceleration rate automatically adjusts the slowdown distance to the correct value to suit the selected deceleration rate. The calculation is done repetitively at high speed to minimize any lag between the diminishing target distance and the corresponding velocity pattern. Further adjustments permit control of the final tapering off from constant deceleration, with the slowdown distance automatically adjusted to suit these adjustments also.
摘要翻译：一种用于产生用于诸如电梯轿厢的车辆的速度模式的系统，该系统必须平稳地顺利地停止与多个站中期望的一个站精确对准的停止。车辆与需要停车的车站之间的距离（目标距离）以数字形式表示，并以电子方式进行处理，以产生速度模式，该速度模式在整个过程中除了初始构建之外导致车辆的恒定减速从而使恒定减速度最终逐渐减小。减速率的单次调整会自动将减速距离调整到正确的值，以适应所选的减速率。计算以高速重复进行，以最小化目标距离减小与相应速度模式之间的滞后。进一步的调整允许从恒定的减速度控制最终的逐渐减小，随着减速距离的自动调整也适合这些调整。

摘要： A vapor recovery nozzle, employed in minimizing atmospheric pollution by fuel vapors is described. The nozzle comprises a bellows which is compressed against the fill pipe of a vehicle fuel tank during discharge of fuel therein. The bellows surrounds a nozzle spout to define a vapor return flow path which extends through a nozzle body. The body of the nozzle is compositely formed by a body member and a vapor path cap which compositely define the vapor return flow passage. Flow of fuel is controlled by a control valve which may be opened, or maintained opened, by an operating lever only when a trip mechanism stem is latched in an operative position. A mechanical interlock prevents latching of the trip mechanism stem unless the bellows is compressed in sealing engagement with a fill pipe. When the bellows is so compressed, the trip stem is latched. If the level of fuel in the fill pipe covers the end of the spout, vacuum actuated means unlatch the trip mechanism stem. If the pressure in the vapor return flow path rises to a level indicating a blockage in return flow, the trip stem is also unlatched. A vapor valve is provided in the bellows to prevent the escape of fuel vapors when the nozzle is in a rest position. Angular relationships of the bellows and the spout facilitate obtaining a seal with a fill pipe. A groove is formed in the spout outwardly of and adjacent the vapor seal so that the vapor seal maintains its integrity in the event the spout is broken when inserted in a fill pipe. A trip mechanism sub-assembly, a spout sub-assembly and a bellows sub-assembly facilitate rebuilding, as well as the original assembly, of the nozzle.
摘要翻译：描述了用于使燃料蒸气中的大气污染最小化的蒸气回收喷嘴。喷嘴包括在燃料排出期间压缩在车辆燃料箱的填充管上的波纹管。波纹管围绕喷嘴喷口以限定延伸穿过喷嘴体的蒸汽返回流动路径。喷嘴的主体由主体部件和复合地限定蒸汽返回流动通道的蒸气通道帽复合地形成。只有当跳闸机构杆被锁定在操作位置时，才能由操作杆打开或保持打开的控制阀来控制燃料的流动。机械互锁防止脱扣机构杆的闩锁，除非波纹管与填充管密封接合而被压缩。当波纹管被压缩时，跳闸杆被锁住。如果填充管中的燃料水平覆盖喷嘴的端部，则真空致动装置解除脱扣机构杆。如果蒸汽返回流路中的压力上升到表示回流阻塞的水平，则脱扣杆也被解锁。在波纹管中设置蒸气阀，以防止当喷嘴处于静止位置时燃油蒸汽逸出。波纹管和喷嘴的角度关系便于利用填充管获得密封。在蒸汽密封件的外部和邻近蒸气密封件处形成凹槽，使得蒸汽密封件在插入填充管道时在喷口破裂的情况下保持其完整性。跳闸机构子组件，喷口子组件和波纹管子组件便于喷嘴的重建以及原始组件。

摘要： A vacuum assisted, vapor recovery fuel nozzle comprising a nozzle body and a spout mounted thereon. The spout comprises an inner tube and an outer tube. The inner tube and a passage in the body provide a fuel passage. The inner and outer tubes define a vapor return passage in the spout. The inner end of the outer tube is provided with a radial flange, which is clamped, by a breakaway nut, on the nozzle body to mount the spout thereon. The nozzle is provided with an automatic shut off mechanism, which includes a venturi valve for generating a negative pressure. In the absence of an overfill condition, this negative pressure is vented to atmosphere through a vent tube disposed in the vapor return passage. A normally closed vapor return valve, mounted on the nozzle body, is opened in response to the nozzle's flow control valve, so that vapors will be drawn into the entrance of the vapor return passage at the outer end of the spout. The spout is formed by telescoping the inner tube into a ferrule and the ferrule into the outer tube to provide a reenforced outer end for the spout. The nozzle body is compositely formed by a body member, a vapor cap and a housing for a main valve trip mechanism. The coaxial hose is attached to the hand grip of the nozzle at a downward angle. An optional, vestigial shroud is provided to prevent escape of vapors during delivery of fuel.

摘要： A system for controlling the loading of fuel into a multi-compartmented transport tank interrupts loading of fuel when the level of fuel in any compartment is above a given upper level and prevents loading when the level of fuel is above a given lower level. Fail safe operation is provided by top and bottom liquid level sensors which generate a "dry" signal to indicate that the liquid level is below the upper and lower levels in each compartment. A "dry" signal from the bottom sensor is required to initiate loading of a compartment. Once initiated, a substitute signal permits continued loading of the compartment. The "dry" signal is a pulsing electrical signal which cooperates with a multivibrator to generate a signal for each compartment indicating that loading of fuel is appropriate. Indicia lights are provided for each compartment to indicate the level of fuel in each compartment. Diagnostic means enable these lights to identify the failure of a sensor or a faulty electrical connection therewith. A dummy, "dry" signal generator permits the use of the control system circuitry with tanks having a different number of compartments.

摘要： An emergency valve is provided to shut off the flow of fuel in the event a fuel dispenser is struck with sufficient force to rupture the fuel conduit means therefor. The valve comprises a lower housing connected to a source of pressurized fuel and an upper housing connected to conduit means which extend to a dispensing nozzle. The upper housing has a groove which defines the plane of a weakened portion. When the impacted with a relatively high lateral force, the portion of the upper housing, above the groove, will separate, or break away. A normally open, main control, flapper valve is mounted in the lower housing. A poppet check valve is mounted in the upper housing. When the separable portion of the upper housing breaks away, both the flapper valve and the check valve automatically close to minimize spillage of fuel. A bleed valve is provided to relieve pressure in the fuel conduit means to which the separable portion of the upper housing is connected, in the event a fire occurs upon its breaking away. In one embodiment the check valve yieldingly engages a seat formed in the upper end of the upper housing, immediately above the notch and is opened by fuel flow pressure. In another embodiment the check valve is normally held open by a post projecting upwardly from a bridge mounted beneath the groove. In a third embodiment, the poppet valve is also held in an open position by a similar post and is engageable with a seat formed in the upper surface of the upper housing. The upper housing and check valve comprises a replacement unit which can be mounted on existing lower housing to provide the benefits of the present invention or to replace an upper housing when an accident occurs.

摘要： A sealing unit effects a connection between a loading boom and a manhole on a tank car. Liquids are delivered through the boom into the tank car. Vapors displaced from the tank are transmitted, through the sealing unit, to conduit means, which enable disposal of the vapors without contaminating the atmosphere. The unit comprises an upper plate which rests on the manhole. A sleeve is connected at its upper end to the upper plate and, at its lower end, to a lower plate. A pneumatic motor is actuated to draw the lower plate upwardly. When this occurs, the sleeve is bulged outwardly into sealing engagement with the manhole. Column springs are provided to assure that the central portion of the sleeve will bulge outwardly and provide sealing engagement with manholes of different diameters.
