Patent DE-3136154-A1 (DE)
Title: Motion-controlled electrical switch
Inventor: HIRCHE MANFRED
IPC: H03K17/94
Filed: 1981-09-09
Abstract: Light switches which are operated either by a timer (or similar) or usually manually are used in the private domain but also in industry. This results in problems: light is not regularly switched off, the switch cannot be easily found in windowless rooms. The switch designated above switches on, for example, the electrical illumination by means of movements (of persons). If further movements occur within a few minutes (internal holding time), the electronics are retriggered. The light then automatically switches off after the room is left. Applications are, for example, walk-in wardrobes, store rooms and cellars. In addition, it can also be used as an alarm system.
Patent DE-3138036-A1 (DE)
Title: Clamping device
Inventor: MUENKER PETER
IPC: C25D17/06
Filed: 1981-09-24
Abstract: A clamping device for electrochemical surface treatment of workpieces which are to be treated consists, within a clamping region, of two live (current-carrying) clamping members (2, 3) which rest against the workpiece (12) which is to be treated, on different sides, at a clamping point. In this case, the clamping element (4) which varies the position of the flexible clamping member is not live (does not carry current). All these clamping elements are allocated on one side of the live carrier (5) on which the contact members are fitted. It is thus possible to operate the clamping device easily from one side, without the clamping process damaging the surface of the workpiece which is to be treated. <IMAGE>

Patent DE-3209251-A1 (DE)
Title: Method for forcing fluid which is located in a container in the weightless state towards outlet flow openings, and a device for carrying out the method
Inventor: STROBL HEINRICH ING GRAD
IPC: B64G1/40
Filed: 1982-03-13
Abstract: This method is used for forcing fluid (4) which is located in a container (1) in the weightless state towards one or more outlet flow openings (2). In order to ensure that, as far as possible, only fluid is drawn off at the outlet flow opening (2) it is provided for fluid, especially in the form of fluid droplets (3) to be sprayed in through a nozzle (7) which is arranged in the container wall opposite to the outlet flow opening, with pulsed components directed towards the outlet flow opening (2). In consequence, the fluid, which fills the individual spatial regions (4) and is located in the container (1), is forced towards the outlet flow opening (2). The fluid which is to be sprayed in can be drawn off through the outlet flow opening (2) itself, and can be brought to a higher pressure by means of a pump (5). In order to make fluid available at the outlet flow opening (2) even at the start, a porous system (11) can be arranged there, in a form like a sponge. Finally, a portion of the drawn-off fluid can be supplied to a fluid consumer (6), for example flight-path correction motors (14, 15, 16). <IMAGE>

The invention provides for the application, to the layer to be etched, of a masking layer which is attacked during plasma etching by the etching gas used. The chosen thickness of said masking layer is such that it is not completely removed when the openings are ion-etched. This produces openings with bevelled side walls.
Patent DE-3215868-A1 (DE)
Title: Method and arrangement for recognising the words in a continuous word chain
Inventor: NEY HERMANN DIPL PHYS
IPC: G10L15/00
Filed: 1982-04-29
Abstract: Individual words are recognised in a continuous word chain in similar fashion to a word spoken in isolation, through comparison following non-linear time adaptation in which a sequence of combinations in each case of a test signal derived from the speech signal and a reference signal is sought, for which sequence the summed differences produce a minimum. Since the word boundaries in a continuous word chain are initially unknown, the speech signal must be compared repeatedly with the reference samples of all words of the predefined vocabulary. The reference samples in each case of one word comprise a sequence of individual reference signals. In each case at the end of a sequence of reference signals, specific transition rules are applied for the transition to a new sequence of reference signals. Furthermore, backward pointers are stored which, on the basis of the sequence with the smallest difference sum at the end of the speech signal enable a backtracking of the optimum time adaptation path. The memory space requirement is linearly dependent on the number of words of the vocabulary and the permitted or predefined length of the speech signal. The arrangement for carrying out the method which is also described essentially comprises only these memories and a small number of additional elements, in particular a comparator and a number of intermediate registers, and is thus of simple design. <IMAGE>

Patent DE-3228590-A1 (DE)
Title: Amplification and equalisation device for AC signals in the time division multiplex method
Inventor: PIERREL HANS JOACHIM
IPC: H04B3/08
Filed: 1982-07-30
Abstract: The invention relates to a circuit arrangement for an amplification and equalisation device for AC signals in telecommunications systems. The equalisation by the amplification of the amplifier device (VE) is to be controlled over the entire intended frequency band, dependent on a control parameter, in the simplest possible fashion. For this purpose, the output signal (A1) of the amplifier device (VE) is sampled by a level comparison device (PVE, E2). With the aid of reference voltages, the level comparison device (PVE) generates a control voltage and controls (via R4, R7, C3) a switch (T1) which in turn controls a DC current (Is) by means of two diodes (D1, D2) which, with resistors and capacitors (R1, C1, C4) (R2, R3, C2), in each case form a discharge path for AC signals which is connected to a control input (E1) of the amplifier device (VE feedback input E1), thereby controlling the AC resistance of said diodes. Through corresponding selection of the capacitors (C1, C2), the discharge paths are used for different frequency ranges. The level comparison device (PVE) can be connected to a control device (STE, E3, A2) which, via a further switch (T2), allows the diode resistance to be controlled only at the beginning of a signal block. The circuit arrangement according to the invention can be used in any telephone station with an amplifier. <IMAGE>

Patent DE-3300584-A1 (DE)
Title: Radiator reflector
IPC: F24D19/06
Filed: 1983-01-11
Abstract: It represents an additional insulating means for saving energy in radiators fitted on exterior walls, especially in radiator recesses. Particularly large energy losses occur at these locations, determined by very high temperature drops between interior and exterior (high temperature of the radiator and small wall thickness). Guide tracks are fitted to the wall to solve the problem. As is to be seen in the drawing, a flexible reflector element, which is assembled like a blind from individual plates, is introduced into these tracks. Mounting can be effected easily and without having to detach the radiator, even when the distances between the wall and the radiator are small. The resulting interspace is filled with insulating material, e.g. by applying foam. The reflector plates are made as far as possible in a curved shape (sunlamp effect), in order to increase the reflecting surface. The incident radiant energy from the radiator is radiated back by the reflecting surface and the insulation combined therewith, and is optimally used. One of the reflector plates is constructed as a hollow body (evaporator). An agreeable climate is produced by the evaporator which can be filled with liquid. Energy is saved as a result of these measures. An exemplary embodiment of the invention is [shown] in the drawing ... Original abstract incomplete. <IMAGE>

Title: Fuel injection system for motor vehicle diesel engines having an electrical starter device including a starting lock
Inventor: FREUDENSCHUSS OTTO DIPL ING
IPC: F02N99/00
Filed: 1983-02-10
Abstract: The object of the invention is a fuel injection system for motor vehicle diesel engines (2), which have an electrical starter device (10) and starting lock (36) and for each engine cylinder (1) an injection element (3) which can be controlled by a solenoid valve as a function of operating state variables of the diesel engine. A reservoir (7) connected by lines to the injection elements (3) can be pressurised by at least one high pressure fuel pump (6) actuable when the motor vehicle is started up. In the case of such a fuel injection system it is proposed according to the invention that, before starting the diesel engine (2), the high pressure fuel pump (6) be independently actuated in order to charge the reservoir (7) or the reservoir (7) be separated from the connecting lines between high pressure fuel pump (6) and injection elements (3) during the starting process. In this way the reservoir is charged up to operating pressure by the high pressure fuel pump before the actual starting process and the full fuel pressure is available to each injection element for actual starting of the diesel engine. <IMAGE>

Title: Device for the distribution and reversal of fluid flows, especially a control device for a pneumatically operated double diaphragm pump
Inventor: LEINKENJOST HANS
IPC: F04B43/073
Filed: 1983-04-16
Abstract: In the case of a device for the distribution and reversal of fluid flows from a fluid source to two working chambers with separate, alternating admission, especially a control device for a pneumatically operated double diaphragm pump, with a control valve in the valve housing of which a control piston is arranged, to which fluid can be admitted at both sides, and with a pilot valve, the control piston of which can be controlled by elements, such as the diaphragm plates of a double diaphragm pump, moved by the fluid, it is proposed to create a solution by means of which the overall size is considerably reduced and effective pressure equalisation can be ensured between the working chambers, and which at the same time makes an emergency starting device possible. This is achieved in that the fluid in the control valve (18) can be alternately fed through a hollow body (25) and through a control element (24) guided thereon by way of corresponding recesses to the respective working chambers (15, 15'), depending on the switch position of the control element (24). <IMAGE>
