摘要： The probe includes a tubular housing having a first portion and a second portion. The first portion is adapted to be mounted in place of the glow plug of a selected engine cylinder. A light pipe within the first portion directs light from the combustion zone to a phototransistor within the second portion. The front of the first portion has a reduced size aperture defined by an internal shoulder against which the front of the light pipe is seated. The rear of the first portion carries resilient sealing means which is deformed when the second portion is telescoped thereon so as to provide a detachable, frictional, light-tight thermally insulated connection therebetween. A phototransistor is mounted within the second portion to convert light passing through the light pipe into electrical signals. A cable carries these electrical signals to processing equipment. A base resistor is located in the second portion between the base of the phototransistor and the cable. The part of the first portion that projects from the engine is short with respect to the part that fits into the engine. The projecting portion carries wrench-engaging bosses.

摘要： A first pulse train is generated by a phase-locked loop circuit of which the frequency is adjustable to correspond to engine speeds of between 10 and 9,990 rpm. The pulse train is again divided to furnish a second pulse train for use in firing the timing light. A photoelectric sensor is responsive to flashes from the timing light. A D type flip-flop is coupled to the second pulse train and to the photoelectric sensor and generates an enable signal commencing with a pulse in the second pulse train and terminating with the sensor signal. A counter receives the first pulse train and is operative to count the pulses therein during the presence of the enable signal. A display depicts a number representative of the number of pulses counted by the counter.

摘要： There is disclosed a transducer to sense the vacuum in the intake manifold of an engine or other chamber. The electrical signal it produces is converted into digital signals for operating a liquid crystal display. The output of the transducer is also coupled to a driver which is operable in one mode to produce energizing currents on all of its outputs corresponding to the amplitude of the electrical signal. The driver is coupled to LEDs which are thus illuminated. The driver is also operated in a second mode so that only one of the outputs is energized and in that mode the driver receives only the AC component of the transducer output.

摘要： A spring winder includes a base and a mandrel rotatably held against the base by a pair of mounting blocks which include aligned grooves in which the mandrel is seated. Each block is connected to the base by a pair of mounting screws which cooperate with associated compression springs for resiliently holding the mandrel between the mounting blocks and the base with a variable force. A length of spring wire is fed between a cam and washer rotatably mounted on the side of the base by means of an adjustment screw, the wire then being fed through an aperture in the adjacent end of the mandrel. The cam and washer are resiliently urged together by a compression spring for applying a drag to the wire which is variable by adjustment of the associated screw. A pin on the washer rides in a complementary groove in the cam for retaining the wire in position. As the mandrel is rotated the wire is wound thereon against the drag of the cam and washer to form a series of helical coils. The cam has a wedge-shaped camming surface thereon which is insertable between adjacent coils of the wire on the mandrel to establish the spacing between adjacent coils. Rotation of the cam permits adjustment of this spacing. A double-wedge cam is also disclosed for forming either right-hand or left-hand springs.

摘要： A transducer produces a sequence of pulses corresponding to the compressions in the chambers of an internal combustion engine. Gating signals are produced in substantial time coincidence with these compression pulses. A number of channels are coupled in parallel corresponding to the number of chambers of which compression is to be measured. The channels are successively rendered operative by the gating signals which detect the amplitude of the compression pulses, by peak detection or counting clock pulses, for example. An annunciator is coupled to the several channels to express sequentially the information stored therein.

摘要： A capacitive pickup device for deriving a measurable voltage which is a linear function of the magnitude of pulsating high voltage of the order of 15 to 40 kilovolts in an insulated conductor, the pickup device having a pair of electrically conducting plate members connected together electrically to form one plate element of a capacitor, the conductor itself forming the other plate element of the capacitor and the conductor insulation forming the dielectric. The pickup device also includes a pair of electrically conducting plates respectively carried in spaced relation with the plate members, the plates being centrally relieved to accommodate the plate members and adapted to be connected to ground. An indicating and protective gaseous conduction lamp is electrically connected between the plate members and plates, and a capacitor and a resistor are connected in parallel across the lamp to form an output circuit for connection to apparatus for indicating in linear manner the magnitude of the high voltage in the conductor. The plate members and plates are relatively movable so they selectively may open and close for receiving a portion of the insulated conductor without requiring conductor disconnection.

摘要： A polygonal bit is frictionally retained in a mating socket opening of a drive socket by the provision of recesses in the flat surfaces of the bit, the formation of each recess creating a raised ridge of material displaced from the recess and projecting from the flat surface around the perimeter of the recess for frictional engagement with the corresponding drive surface of the drive socket. Recesses may be formed in flat surfaces on opposite sides of the bit, with one or two recesses being formed in each such surface. Various shapes of recess are disclosed.
