Title: Multiple bulb flash device
Inventor: SHAFFER JOHN W
IPC: G03B15/04
Filed: 1981-10-29
Abstract: A photographic flash device has a horizontal linear row of flash bulbs, which are enclosed in a one-part housing, which has a transparent front part, which is folded round a rear part, which has a plurality of cavities to receive the bulbs, in each of which the bulbs are arranged. A printed circuit board is combined with the housing, and a pair of leads to each of the lamps is connected to conducting circuit patterns, which are disposed solely on one side of the circuit board. A multiplicity of connection surfaces are assigned to the circuit patterns, which connection surfaces are arranged next to each other on a flat tab, which projects from one edge of the circuit board, in order to be inserted into the receiving socket of a source of trigger pulses. The tab contains a multiplicity of symmetrically arranged openings or rebates, by means of which the tab is able to detachably engage with socket components independent of the trigger pulse contacts, in order to hold the device firmly in the socket. <IMAGE>

Patent DE-3219879-A1 (DE)
Title: Sunshade or wind break
Inventor: SCHAEFER KONRAD
IPC: E04H15/00
Filed: 1982-05-27
Abstract: The invention relates to a sunshade or wind break having at least two adjacent wall parts, each of which is substantially formed from a flexible web of material. In order to avoid the necessity of using rigid supports such as rods or the like and in order to be able to fold up the sunshade or wind break into a minimum space, it is proposed, according to the invention, that the sides of the wall parts are each designed as inflatable chambers and that, in the position of use of the sunshade or wind break, two wall parts bear against each other in the manner of a roof. Erection is simple since only the chambers located at the sides of the wall parts need to be pumped up, as a result of which the necessary dimensional rigidity is also guaranteed. Supporting rods or similar aids are not necessary. When not being used, the sunshade or wind break can be folded up in a very constricted space.

Patent DE-3231519-A1 (DE)
Title: Compressed air production system
Inventor: REPPICH ANDREAS
IPC: B01D53/26
Filed: 1982-08-25
Abstract: The invention proposes a compressed air production system with a compressor which has an air drying system with two drying vessels which can be switched over to alternately dry the compressed air flowing through them or regenerate the desiccant using part of the dried compressed air. The switch-over facility is combined with a timing facility in an electronic timer element (13) which is matched to the delivery times of the pressure regulator (2) with the aid of a pressure switch (15). This ensures that uniform lowering of the dew point is possible with all switch-on cycles and times of the pressure regulator. The compressed air production system can be used for preference in air brake systems of motor vehicles. <IMAGE>
Patent DE-3231768-A1 (DE)
Title: Equaliser with adaptive quantised feedback
Inventor: HENTSCHKE SIEGBERT DR ING
IPC: H04L25/03
Filed: 1982-08-26
Abstract: An equaliser with adaptive quantised feedback to equalise a severely distorted digital received signal is improved according to the invention by using a frame alignment word, transmitted at periodic time intervals to the receiving end, in the equaliser at the receiving end to re-adjust the coefficients. This is achieved by using, at times when the frame alignment word is received, a distortion-free frame alignment word which is identical to the former frame alignment word and which is stored in a memory (9) at the receiving end, instead of the output signal of the quantiser (3), for coefficient re-adjustment. This achieves a fast convergence of the coefficient re-adjustment, and a test signal which would otherwise normally precede the data transmission is no longer required. A linear equalising component (10, 11), connected if necessary upstream from this equaliser, uses the same error signal for coefficient re-adjustment, where the receiving-end frame alignment word is used at periodic intervals to determine this signal. The changeover from the output signal of the quantiser (3) to the frame alignment word stored in the memory (9) is provided by a frame recognition circuit (8) which is required in any case in the receiver for the purpose of phase synchronisation of the receiving-end sampling clock. <IMAGE>

Title: Voltage-controlled resistor
Inventor: JONES RONALD R
IPC: H03H11/46
Filed: 1983-06-13
Abstract: A voltage-controlled resistor exhibits an operational transconductance amplifier (OTA) which has a first and a second linearisation diode which optimise not only the signal/noise and distortion ratio but also represent the alternating-current impedance from inverting input to earth. The OTA switches on and off in dependence on the magnitude of the gain control current supplied to it. The output of the OTA is connected to a Darlington transistor in order to create a buffered low-impedance output. A first resistor provides for a current flow through the diodes. A feedback resistor supplies and controls the current flow to one of the diodes. A third resistor maintains a bias to the Darlington pair when the output of the OTA approaches impedance conditions of an open circuit.
