摘要： The slide projector (4) for single-slide, lap-dissolve or stereo projection, which works on the gravity feed principle, is designed for operation with linear slide trays (1, 2) divided into compartments. At the top, it has either two receptacles for slide-tray covers (2, 5) or one receptacle (4g) and one cover (4h) integral with the housing of the projector. When being placed on the projector, the slide tray is automatically unlocked, so that the housing of the tray becomes shiftable. Switching means ensure that the projector cannot operate until the slide tray is properly positioned. The projector also has a variable electronic light intensity control facility. It initiates no projection when a tray compartment is empty.The slide tray (1, 2) is so designed that slides are loaded into the housing (1) of the tray from above in an upright and laterally correct image position; the housing (1) is then closed with the cover (2). During projection, the cover forms the bottom of the slide tray.
摘要翻译：适用于重力进给原理的单滑块，搭接式或立体声投影机的幻灯机（4）设计用于分为隔间的直线滑动托盘（1,2）。在顶部，它有两个用于滑动托盘盖（2,5）或一个插座（4g）的插座和一个与投影机壳体一体的盖子（4h）。当放置在投影机上时，滑动托盘自动解锁，使得托盘的外壳可以移动。切换装置确保投影机在滑块正确定位之前无法操作。投影机还具有可变电子光强度控制设备。当托盘舱是空的时，它不会启动投影。滑动托盘（1,2）被设计成使得滑块从上方以直立和横向正确的图像位置装载到托盘的壳体（1）中; 然后用盖（2）关闭壳体（1）。在投影期间，盖子形成滑动托盘的底部。

摘要： The invention relates to a parallelepipedic tray intended to accommodate slides (7) which are to be viewed. The tray mainly comprises an upper wall (1) and a lower wall (2) each of which has grooves (6). The slides can be inserted in or removed from the tray via either of two open side surfaces, and to prevent the slides from dropping out when the tray is being handled, the tray has two flaps (8 and 9). Such a tray can be used on a slides viewer which has two carriages (22 and 23) to support and guide the trays, which carriages are disposed symmetrically on either side of optical system (28).
摘要翻译：本发明涉及一种用于容纳待观察的滑板（7）的平行六面体托盘。托盘主要包括上壁（1）和下壁（2），每个壁具有凹槽（6）。幻灯片可以通过两个开放的侧面中的任一个插入托盘或从托盘中取出，并且当托盘被处理时，防止滑块脱落，托盘有两个折板（8和9）。这种托盘可以用在具有两个托架（22和23）的滑架观察器上，以支撑和引导托盘，托架对称地布置在光学系统（28）的任一侧上。

摘要： A slide projector is juxtaposed with a slide magazine in a housing. One of the projector and magazine is movably mounted so that each slide may be aligned with where it may be loaded into the projector and unloaded back into the magazine. At the loading station a pair of pivotable, opposed toggles operated by an eccentric device frictionally rollingly grip and release two opposite edges of the slide with reversibly driven rollers. In a disclosed elaboration, a plurality of slide magazines are disposed on a spider, which may be rotated to bring any selected magazine into juxtaposition with the projector. In the elaborated version shown, the slide projector is laterally movably mounted for temporary retraction during indexing of the spider.

摘要： The present invention relates to a projector comprising two optical systems enabling transparencies to be projected with cross-fading, in 3-D and with double-width panning, said projector operating with a single transparency distributing and recuperating magazine, in which the transparencies are arranged in the same order as if they were to pass in a single-lens projector; said projector comprises four parallel transparency guide slots, which are parallel to one another and transverse with respect to the axes of two optical systems in which the transparencies circulate in pairs, said guide slots being extended by a switching means whose role is to cause the transparencies which have already been projected to pass from the forward guide slots into the return guide slots, and thus to cause the transparencies to return to the same compartment of the same magazine from which they left. These displacements are possible due to a recuperator having multiple functions. Simultaneously to the displacement of the recuperator, a double potentiometer in relation with an electronic device effects cross-fading. This projector may be used for simple projection, but without a gap between two transparencies, for 3-D and for double-width panning.
摘要翻译：本发明涉及一种投影仪，其包括两个光学系统，其使透明胶片以三维投影方式投射，并且具有双倍宽度的平移，所述投影仪使用单个透明度分配和恢复盒来操作，其中透明胶片被布置按照相同的顺序，如果他们要通过单镜头投影机; 所述投影仪包括四个平行的透明导向槽，它们彼此平行并相对于两个光学系统的轴线横向，其中投影胶片成对地循环，所述导向槽由转换装置延伸，其作用是使透明胶片这些已经被投影从前进导槽插入到返回引导槽中，从而使透明胶片返回到他们离开的同一盒的同一个隔间。由于具有多种功能的换热器，这些位移是可能的。在同步换流器的位移的同时，与电子设备相关的双电位器会产生交叉衰落。该投影机可以用于简单的投影，但是在两个透明胶片之间没有间隙，用于3-D和双宽度平移。

摘要： A magazine-type slide projector has a single slide projection accessory that is removably placeable across the magazine track. The accessory has a slide compartment positioned on the slide changing plane, and the compartment has an open top edge and an open side edge facing the slide projection position. The accessory allows manual insertion and removal of single slides through the top opening of the compartment for movement of the slides into and out of the slide projection position by the slide changing device. The projector also preferably has a storage compartment where the accessory can be conveniently stored when not in use.

摘要： An arrangement for controlling the advance of a magazine in a transparency projector in which a fork advancing the magazine, is subjected to the action of a return spring having one end constantly fixed to a control member which is pivotally mounted about a fixed axis. An operating member having a cam-shaped portion cooperates with the control member so that the advance of the operating member towards the fork initially pivots the control member due to the action of the cam-shaped portion. The fork becomes thereby pivoted by the return spring until the extreme position is reached, in which the fork is locked against the magazine. When the operating member is withdrawn, the fork is released from engagement with the magazine.

摘要： A slide projector adapted to alternately receive at least two slide trays having different shapes and different indexing configurations is provided. The projector comprises a slide tray receiving groove having tray guide means for slidably engaging corresponding support surfaces formed on the slide trays, and a reversible slide tray indexing mechanism having an indexing lever mounted for slidable and pivotable movement and including a pair of pawls for sequential engagement with the respective indexing racks of the alternate trays, to incrementally advance either of said trays from one slide position to the next. A reciprocal slide carrier for transporting the slides from the trays to the viewing position is provided with a camway in operative engagement with the indexing lever to impart the required movement thereto during each slide changing cycle. The projector also includes slidable tray retainer means formed as a part of the tray guide means to support the edge of one of said trays to maintain the same in engagement with the indexing mechanism.

摘要： In a slide projector a plurality of slide films contained in a tray are successively selected and shifted to a projected position. A switch is provided which controls movement through a clutch to a running motor of each slide film between its tray-stored position and its projection position and also movement of the tray itself. This switch serves also as a switch for resetting a timer which holds each slide film in its projected position for any desired time.
