Title: Cam drive, in particular for hand power tools
Inventor: UEBEL PHILIPP
IPC: F16H25/14
Filed: 1981-01-23
Abstract: The invention proposes a cam drive, in particular for hand power tools, which converts a rotary driving movement in a constant direction of rotation into a reciprocating stroke movement of the tool while simultaneously providing a reduction of the said driving movement and, in a space-saving construction, uses for this purpose two control tracks which are arranged separately from one another, extend over the same stroke length, with a 0 slope and, are formed by a rotating control body and have an oppositely directed slope and uses a tracer for each of these control tracks. According to one of the illustrative embodiments, the cam drive comprises a rotating control body (65) with two control grooves (67, 68) and two balls (69, 70) which serve as tracers for these control grooves and are connected to a part of the mechanism which carries out the stroke movement, a guide sleeve (61) and to one another via a series (64) of balls guided in a channel (63). This gives mutual positive control of the balls (69, 70), the respective tracer (69, 70) forced out of engagement with its control groove (67, 68) by the run-out part of the said control groove forcing the other tracer (69, 70) into the tracing position relative to its control groove (67, 68) via a run-in of the said control groove. <IMAGE>

Patent DE-3114310-A1 (DE)
Title: Device for sealing joints
Inventor: KOCH HELMUT
IPC: E04F21/165
Filed: 1981-04-09
Abstract: The device is used for sealing joints in masonry structures, panels and the like. Vertically running joints are extremely time-consuming to seal. Without this device, only small amounts of joint-sealing means can be introduced into the joints if the aim is to avoid, for example, porous masonry structures being smeared and irreparably soiled. The device also has considerable advantages for horizontally running joints. The amount of joint-sealing composition in the receptacle is many times greater than that which is possible on a straightforward mortar board. Figures 2 and 2a show one embodiment. The receptacle can be of virtually any shape. The slot (3), which is adapted to the width of the joints and of the jointer, and can be altered in accordance with 2a, is essential to the invention. As a result, per unit of time, considerably larger amounts of joint-sealing composition than would be possible without this device can be pressed into the joints. Quite apart from the saving in material by falling material, the saving in labour is, in accordance with time and motion studies, 30% for horizontally running joints and 60% for vertically running joints. <IMAGE>

Title: Section for ceiling formwork
Inventor: ROMPPEL EDMUND
IPC: E04G11/36
Filed: 1981-05-29
Abstract: The invention relates to an iron channel section with a flat rail and a fixing wedge, for vertical formwork of reinforced concrete ceilings. It is also possible to form a jamb wall from outside using a longer rail. As shown in the drawing, the article consists of a channel rail of the required thickness, depending upon loading. The flat rail can be inserted through the joint and, depending upon the wall thickness, can either be angled off internally or be held with a second wedge. The flat rail can also be half-embedded or nailed on. The formwork plank is then placed against it or clamped in between and is tensioned and held by the outer wedge. The spacer welded to the channel rail at the bottom has a thickness of 4 cm. The channel rail has a plurality of slots of standard spacing. The vertical formwork is thus considerably simplified and saves working time. The storage is simplified. <IMAGE>

Title: Front attachment for a window
Inventor: SCHILLING HEINZ-JUERGEN
IPC: E06B3/28
Filed: 1981-06-05
Abstract: Front attachment for a window with a frame (12) projecting beyond the pane (16), which comprises a transparent sheet (10) which can be fitted at a distance from the pane (16). For the purpose of simplified fitting of the sheet (10) while not causing any decrease in the high insulating effect on the room-interior side of the frame (12), use is made of a double adhesive band (14) arranged between said frame and the sheet border (18). The double adhesive band (14) is preferably designed to be transparent in correspondence with the sheet (10). For standard windows, the invention conceives the provision of prefabricated "front-attachment sheets" (10) with a double adhesive band which extends along the border and is provided, on the adhesive side directed away from the sheet (10), with a protective film which can be drawn off. Said protective film is then drawn off before mounting on the inner side of the window frame (12). A front-attachment sheet with "self-adhesive border" is thus obtained. <IMAGE>

Title: Switching device for pressure-dependent operation of a stationary monostable microswitch
Inventor: HAEUSLER GUENTER
IPC: G01K5/36
Filed: 1981-12-11
Abstract: The invention relates to a switching device for pressure-dependent operation of a stationary monostable microswitch, particularly for use in an indicating instrument for a two-position controller. The switching device exhibits a switching sleeve which is axially displaceably guided on a switching shaft by means of a switching cam and the axial displacement of which rotates an operating lever against which an operating plunger of the microswitch rests under spring force. Furthermore, the switching device exhibits a rotary drive for the switching cam which can be rotated around the switching shaft and a carrier which is mounted on a switching shaft. To displace the switching sleeve without jamming and by using minimum driving forces, a switching arm is supported on a carrier and is rotatable about an axis parallel with the switching shaft. The switching arm engages, on the one hand, a receptacle with an axial tolerance which corresponds to the axial switching path of the switching sleeve and can be carried, on the other hand, by the drive over a limited angular range. The switching cam is arranged directly on the switching sleeve, a lifting pin radially attached to the switching shaft resting against the switching cam so that when the switching arm is rotated, the switching sleeve is rotated relative to the switching shaft and the free end of the lifting pin changes its position on the switching cam.

Title: Door fastening for a motor-vehicle door
Inventor: KLEEFELDT FRANK
IPC: E05B85/24
Filed: 1981-12-21
Abstract: The invention relates to a door fastening for a motor-vehicle door. The basic construction includes a housing, a rotary latch designed as a fork latch, a detent pawl with load spring and an actuating device. The arrangement is such that, when the motor-vehicle door is being closed, a closing bolt fastened to the door frame can be introduced into the rotary latch and the rotary latch is moved into the closing position, a force derived from an elastically deformed door gasket acting on the rotary latch in the opening direction. The actuating device is an electromotive actuating device which includes an actuating slide having two control stops, a toggle-lever arrangement with two lever links connected in a dead-centre joint and with an override spring, and an electric motor with a crank mechanism. The actuating slide is connected to the crank mechanism. The toggle-lever arrangement is articulated, on the one hand, on the rotary latch and, on the other hand, on the housing. It is held, in the closing position of the rotary latch, against a barrier in a beyond dead-centre position, pressed towards the crank mechanism. The control stop located on the crank mechanism bears against the dead-centre joint. During a rotation of the crank mechanism out of the position of rest, the toggle-lever arrangement is first pressed by the control stop on the dead-centre joint beyond the dead-centre position into a beyond dead-centre position opposite the first-mentioned. Immediately thereafter, the detent pawl is pivoted into the free position by the control stop which is the lower in the drawing. <IMAGE>

Title: Method and device for calibrating an incremental measuring device
Inventor: SAXER STEFAN
IPC: G01D18/00
Filed: 1982-03-31
Abstract: In this method, first one read head (15) and then the other read head (17) is moved over the reference mark (16 and 18 respectively), for calibration. As soon as the read head (15) is moved over the reference mark, the reference mark signal thus generated has the effect that a set value contained in the set value memory (35), which corresponds to the distance between the measuring probes (11, 13), is loaded into the cleared up/down counter (19). Also from the instance of moving over the first reference mark (16), the read pulses generated by the read head are counted, the direction discriminator (25) specifying the direction of counting. A displacement of the read head (17) only causes the read pulses generated by it to be counted when it moves over the reference mark (18). A direction discriminator (27) again determines the direction of counting. In this method, only counting processes are necessary for calibration so that no addition devices are needed. <IMAGE>
