Patent DE-3728104-A1 (DE)
Title: Arrangement for optical beam guidance by means of prisms
Inventor: BANDEMER ADALBERT DIPL ING
IPC: G02B13/10
Filed: 1987-08-22
Abstract: The invention relates to an arrangement for optical beam guidance by means of prisms. In contrast to conventional beam widening arrangements with two lenses having fixed focal lengths, the optical beam is guided by means of prisms. By changing the angle of incidence into the prism, the widening of the beam in this case is rendered capable of being adjusted continuously and separately in one dimension. The optical losses, when the beam passes through the prism, are in this case considerably lower than in the case of conventional two-lens widening systems. At the same time, the prism deflects the beam in such a manner that compact optical constructions with folded optical beam paths and beam diameters which can be adjusted separately in each direction can be implemented.

Title: Ventilating apparatus for windows and/or French windows for the recuperative ventilating and venting of lounges (recreation rooms)
Inventor: WETZEL ALFRED DIPL ING
IPC: F24F12/00
Filed: 1988-01-29
Abstract: The ventilating apparatus (1) for windows and/or French windows (2) serves for the recuperative ventilating and venting of lounges, in particular for housing construction. The invention relates to the provision of a sound-insulating and heat-insulating ventilating apparatus on the window or French-window element, the frame or sash frame comprising plastic hollow-chamber profiles, and the supply duct and the discharge duct for the fresh air (13), which is to be channelled into the room, and for the warm waste air (12), which is to be channelled out of the room, respectively, in the hollow-chamber profiles extending over the periphery of the frame or sash frame in the form of a convection recuperator in accordance with the countercurrent principle, such that the inflowing, gradually warming, rising fresh air (13) and the outflowing, gradually cooling waste air (12), guided downwards in countercurrent with respect to the fresh air, flow through the frame or sash frame over the entire height thereof. In this arrangement, in addition to the sound-insulating effect, account is also taken, in a particularly simple and expedient manner, of the energy-saving requirements given in accordance with the current state of the art by tightly closing windows during the cold-weather period, without preventing the discharge of used, humid interior room air, but, by supplying warmed-up fresh air, ensuring that good room air conditions are maintained. <IMAGE>
Patent DE-3804634-A1 (DE)
Title: Highly dynamic electrical servo drive with a plurality of asynchronous machines
Inventor: KENNEL RALPH DR ING
IPC: H02P5/747
Filed: 1988-02-15
Abstract: Special measures are required to proportion the torques from a plurality of asynchronous machines to an individual load. In the case of highly dynamic servo drives, these measures ensure constant proportioning and avoid oscillations (vibration) even during rapid torque changes. Exact torque proportioning can be achieved in all control ranges by driving the individual asynchronous machines via separate invertors having switching transistors to which the same drive signals are applied, especially pulse-width-modulated control pulses. In this case, superordinate control loops or special devices for matching the asynchronous machines to one another can be avoided. This servo drive is particularly suitable for fast-reaction drives for individual shafts of numerically controlled, relatively high power machine tools. It can be used whenever mechanical coupling of the drives to one another is provided or whenever an exactly identical position is not required.

A handle (39), which serves for pushing the device, is connected to the spars (7, 8, 9) on both sides of the chassis (1) and thus serves at the same time for tilting the spars (7, 8, 9) in order to compensate unevennesses of the ground on which the device is pushed. <IMAGE>
Patent DE-3838677-A1 (DE)
Inventor: DALLMANN HORST
IPC: H04M1/724
Filed: 1988-11-15
Abstract: The invention is based on the object of developing a known mobile radio telephone in such a manner that data losses due to unintentional operation of operating and input elements, particularly by switching- off the radio telephone, are avoided. The object is achieved by the fact that a switching-off command by the microprocessor circuit (25) of the radio telephone (10) is only executed and that the mobile memory (18) can only be taken from the handset (11) when the following conditions are met. There must be no conversation taking place and all settings existing before the switching-off must have been transferred in the form of data into the mobile memory. During the later insertion of the mobile memory, the data stored in it are then transferred into a main memory (26) of the microprocessor circuit (25). The drawing shows a handset in perspective view and a radio transmitting and receiving set (12) connected thereto. <IMAGE>
Patent DE-3839048-A1 (DE)
Title: Protection circuit for protectively insulated apparatuses
Inventor: LAUERER FRIEDRICH
IPC: H02H5/08
Filed: 1988-11-18
Abstract: The essential idea of the invention is the use of a protective screen which reduces potential and prevents touching, around the live parts of the electrical apparatus which is not permanently connected to an earthed conductor. In the event of an earth short, the electrical power supply is interrupted or the protective screen is connected to the earthed mains conductor (protective earth conductor) automatically and without any major circuit complexity (switching complexity), depending on the respective plug position. When handling protectively insulated apparatuses, the proposed protection circuit prevents the annoying electric shocks in the event of air humidity or rain (for example in the case of hand-held drills, hedge trimmers, spray guns), and in the event of penetration by water (for example in the case of hair dryers or hot-air fans), prevents electrocution in the bathtub.
