Patent DE-3128233-A1 (DE)
Title: Electric lighter, in particular for use in a motor vehicle
Inventor: MOVA ANDREA
IPC: B60N3/14
Filed: 1981-07-17
Abstract: Figure 1 shows an electric lighter which, by means of a metal sleeve (10), can be fastened on the dashboard of a motor vehicle and has an ignition plug (14) which exhibits an actuating button (26) at one end and a resistance-heated incandescent plate (22) at the other end. Within the sleeve (10), the ignition plug (14) can be displaced from a rest position into a heating-up position and is held in the heating-up position counter to the force of a compression spring (68). In this arrangement, the incandescent-plate resistance (22), which is constantly connected to a pole of the voltage source which preferably has mass potential, is connected to the other pole of the voltage source via a spring contact (44). The compression spring (68) and a thermal cut-out, which comprises a bimetallic element (60) and a contact bridge (54) and interrupts the heating circuit after the predetermined temperature has been reached, are arranged in the end region of the sleeve (10). The driver holds the ignition plug (14) pressed in for only a few seconds and is thus not distracted for an unnecessarily long period of time.

Patent DE-3129882-A1 (DE)
Title: Lifting device for surface practice
Inventor: HERDTLE GERHARD
IPC: B66C15/02
Filed: 1981-07-29
Abstract: The lifting device enables operating troubles and material losses to be avoided if one or more of the lifting strands break. In normal operation, the safety device does not get in the way. This is achieved by providing a catch strand (29) parallel to the lifting strand (17) and by using a monitor (32) to check whether the cross traverse (21) belonging to the lifting device moves relative to the catch strand. The latter happens if the main strand (17) breaks. <IMAGE>
Patent DE-3132914-A1 (DE)
Title: Electronic control for watering systems
Inventor: KLEISKE HEINZ ARTHUR
IPC: A01G25/16
Filed: 1981-08-20
Abstract: The invention is intended to permit gardens and green areas to be watered fully automatically as a function of the weather conditions. Since a water source with adequate water flow rate per time unit, for example a domestic mains with a small cross-section of the pipes, is not always available for relatively large areas, this system ensures that in each case only one watering unit is fed with the entire amount of water and thus receives the full pressure. After a preselectable time, watering unit No. 1 switches off while at the same time No. 2 takes up the watering. Up to 10 watering units of completely varying designs can thus water areas with very different outlines. By appropriately positioning the switches of the electronic system, it is also possible to water subareas only. The working points of the sensors for sun activity and precipitation can be set by the operator so that strong sunshine does not lead to ineffective watering. <IMAGE>

Patent DE-3313122-A1 (DE)
Title: Slideway cover for machine tools
Inventor: BAUM HERBERT
IPC: F16P1/02
Filed: 1983-04-12
Abstract: For covering devices of the slideways of machine tools which comprise sheet-steel boxes which slide telescopically one into another, the patent application P 3206461.6 describes locking devices between the boxes, which act in such a manner that a relative displacement can only ever take place between two adjacent boxes - pushing in or pulling out - while all the other boxes are in each case locked to the adjacent box in a completely pushed-in or completely pulled-out relative position until they are unlocked by the adjacent box, which can just be displaced relatively, at the end of its displacement travel. In this connection, a locking device is composed of a latching curve and a latching roller, in which the latching roller is prevented from evading the latching curve by a blocking member until the latter is moved out of its blocking position with respect to the latching roller by the relatively displaceable, adjacent box when the latter is completely pulled out or completely pushed in. The present invention further develops the locking device in such a manner that the same pair comprising latching curve and latching roller can lock two adjacent boxes both in their completely pushed-in and in their completely pulled-out relative position to one another, different blocking members acting on the latching roller in the two relative positions. The latching curve is for this purpose designed to be of the same length as the larger adjacent box in the direction of movement ... Original abstract incomplete.

Title: Method for monitoring an electronically controlled wrench or screwdriver
Inventor: POLZER BERNHARD
IPC: H02P25/14
Filed: 1983-07-06
Abstract: The invention relates to a method for monitoring an electronically controlled wrench or screwdriver for system errors. In known wrenches or screwdrivers, it is decided, by way of preset tolerance ranges in the switching-off time, whether a screwing operation is proceeding properly. Since system errors can not be taken into consideration with these decision criteria, it is proposed to introduce a third quantity, which changes with the screwing operation, as monitoring signal with an assigned tolerance range. At least at the switching-off time of the wrench or screwdriver, checks are made as to whether the signals lie within, below or above the tolerance ranges and, by way of a comparison of the comparison results against one another, it is established whether the screwing operation is proceeding properly and/or whether system errors are present.
