Patent DE-3118208-A1 (DE)
Title: Microfilm reader
Inventor: RINN JUERGEN DIPL ING
IPC: G03B21/11
Filed: 1981-05-08
Abstract: A description is given of a reader for microfilms, in which the distance between the imaging object and the glass sheet or plastic film covering the sheet/flat film is held constant in all the positions of the film gate/trap by virtue of the fact that in principle the lens, which can be displaced in the direction of its optical axis, or a support element joined to it in a fixed manner rests on the sheet or film covering the flat film. Direct contact between the lens or support element, on the one hand, and the covering glass sheet or plastic film, on the other hand, is avoided, however, by arranging for compressed air to be blown between these elements from a nozzle so that the lens or the support element floats on an air cushion of low thickness. As a result, scratches are avoided on the sheet or film, and the ease with which the film gate can be displaced is increased.

Title: Cleaning implement for suction cleaning
IPC: A47L9/06
Filed: 1981-08-07
Abstract: The invention relates to a cleaning implement for suction cleaning, in particular a combination suction nozzle, having a slide plate (4) which can be placed on the surface (8) to be cleaned, and having a height-adjustable brush (7) which is arranged between the housing wall (2b) of the cleaning implement and the slide plate (4). In an operating position (not shown), the brush (7) rests on the surface to be cleaned and, in a rest position (illustrated in Figure 1) lies retracted in the nozzle housing (1). The cleaning implement is attached to a dust filter and dust collection system via a suction line (18). For cleaning floors along walls (21), an uncleaned edge strip remains due to the deficient suction effect in the edge region of the cleaning implement. According to the invention, it is proposed to arrange a separate suction channel (9) as a "prepositioned nozzle" (10) in the region of part of the housing wall (2a, 2b), the inflow aperture (13) of which suction channel lies above the surface (8) to be cleaned, said suction channel opening out into the suction line (18). It is now possible with the cleaning implement according to the invention to achieve a cleaning effect, for example right into the corner between the floor and a wall (21). <IMAGE>

Title: Crash helmet visor with cleaning of the field of vision
Inventor: HORLACHER MAX
IPC: A42B3/26
Filed: 1981-09-28
Abstract: This cleaning device for the field of vision comprises a visor wiper device having a wiper arm which can be moved back and forth between two lateral end positions and is guided on a guide rail curved to correspond to the visor curvature, and an actuating device for the wiper arm. The guide rail and the actuating device are covered by a casing and, together with the latter, form a constructional unit which is fixed to the visor. For actuation by hand, a pull cord can be provided which projects from the casing and with which the wiper arm is pulled from the one end position counter to a restoring force, preferably spring force. The actuating device can also contain an electric motor and a chain gear mechanism, whose endless chain, guided in the form of a loop curved like the guide rail, is coupled to the wiper arm. These easy-to-operate cleaning devices guarantee good vision even in poor driving conditions and do not impair the protective function of the helmet since they are ejected together with the visor in the case of impact. <IMAGE>
Patent DE-3140776-A1 (DE)
Title: Device for catching drilling dust and the like for power hand drills
Inventor: SPENGLER DORIS
IPC: B23Q11/08
Filed: 1981-10-14
Abstract: A flexible hollow body is attached to the neck of the power drill in such a way that it can easily be released and surrounds the drill bit. If need be, the end face, which projects beyond the drill bit, is provided with a conformable lip. During drilling, the hollow body, which, for example in Figure 1, is provided at least partly with bellows, is compressed in accordance with the insertion depth of the drill bit and collects the drilling dust or chips which arise. For the tool change and for emptying, the hollow body can easily be removed from the neck of the power drill. The hollow body consists of transparent material and thus enables the drilling area to be seen. Thus the drilling dust or chips are reliably caught in the simplest manner. Despite the device, the power hand drill can be moved freely. The device is easy to use in a cost-effective manner (specifically in Figs. 1 and 4 inexpensive and simple to produce) and is therefore also practicable for the handyman. <IMAGE>
Patent DE-3140865-A1 (DE)
Title: Circuit arrangement for pulsed reflected light barriers
Inventor: DIESING HANS-WOLFGANG
IPC: G01V8/14
Filed: 1981-10-14
Abstract: It has been possible so far constantly to improve the efficiency of pulsed reflected light barriers by increasing the intensity and simultaneously shortening the light pulse. However, these measures are limited by the self-capacitance of photodiodes. A further increase is possible only by raising the subsequent amplifier sensitivity, which leads, however, to stability problems or a high outlay on circuitry. The filtering effect can be excluded by periodic discharging of the diode capacitance before the arrival of a light pulse. The high impedance of MOS comparators can thus be utilised in such a way that the diode is driven in the more sensitive lower region of its voltage characteristic. Since, by virtue of the high impedance, the comparatively inexpensive luminescence diodes can be used just as well as receivers instead of silicon photodiodes, which have a larger area, this further results in an additional colour selectivity. Since, because of the high impedance, the input capacitance of a MOS comparator suffices for the storage of voltage values, it is possible in this mode of operation for compensation of extraneous light effects to be realised particularly simply.

Patent DE-3202966-A1 (DE)
Title: Electrohydraulic drive unit for wings of doors or the like
Inventor: JAEGER LAJOS
IPC: E05F15/50
Filed: 1982-01-29
Abstract: The electrohydraulic drive unit for wings of doors or the like has a piston (9) which can be displaced counter to the force of a closing spring (10) by means of a pump (2) when the solenoid valve (8) is closed, until the end position corresponding to the open position of the wing coupled to the piston (9) is reached. If the pump (2) is then stopped while the solenoid valve (8) remains closed, the closing spring (10) displaces the piston (9) due to slight leakage in the hydraulic system. As soon as this displacement has reached a predetermined slight amount, the pump (2) is briefly put into operation again, with the result that the piston (9) and the wing are once more moved into the abovementioned end position. <IMAGE>
