Patent DE-2910479-A1 (DE)
Title: Paging system for PABX - minimises equipment needed to connect paged person to outside call by using broadcast circuit
Inventor: DILLIG JULIUS
IPC: H04M11/02
Filed: 1979-03-16
Abstract: A caller on an outside line to a p.a.b.x. is connected to the operator. If the called person is not available on his extension, the operator holds the incoming call and dials a "broadcast" code. This connects her directly to a "broadcast" circuit and she makes an announcement over a loudspeaker. The called person can use any extension to answer the broadcast and, by dialling a "broadcast reply code, he is connected directly to the "broadcast" circuit. The operator can then put him through to the outside caller. The advantage of this system is that an additional selector is not occupied while such a call is in progress.

Title: Gas hose leakage protection system - includes pipe section with seat at upstream end for valve plate
Inventor: GOTTFRIED JOSEF ING GRAD
IPC: F17D5/04
Filed: 1979-03-26
Abstract: The leakage protection system is for a hose comprising an inner section through which a gas flows, and a concentric outer one, the intervening space between the sections accommodating a control gas. A pilot diaphragm divides a housing into a chamber pressurised by the control gas and controls a valve in the path of the latter gas, and which is shut when the chamber pressures are equal. A spindle (61) of his valve (32), joined to the diaphgram (33), extends through the pipe section (18) forming the passage for the consumption gas, and the pipe upstream end acts as a seat (63) for a valve plate (62) joined to the spindle. The downstream end of the pipe forms a valve nozzle (66), shut off by a component (67) secured to the diaphragm.

Title: Solderless capillary chip for thermo-compression bonding - has tip section having straight bore with dished region and progressively increasing diameter
Inventor: OZAWA MINORU
IPC: H01L21/603
Filed: 1979-07-07
Abstract: The capillary chip consists of a corundum-precious stone system, e.g. comprising a ruby or saphire. The straight bore of the tip section is of a configuration so as to have a dished region whose inner diameter is progressively increased. The bore has to be very smooth, as mostly gold wire is used with the chip. Otherwise the abraded particles could clog the board. The front region of the capillary chip (1) is heated to an extent that the tip of a wire (3) melts and forms a sphere. The latter is pressure secured to the base plate with simultaneous bending of the remaining wire. The upper protruding wire portion is then severed.

Title: Radio receiver circuit displaying preset transmit frequencies - has programmable fixed value memory for transmit frequencies, interrogated by clock pulse generator and counter
Inventor: ZIMMERMANN HORST ING GRAD
IPC: H03J1/00
Filed: 1979-09-03
Abstract: The circuit containing a radio receiver has manual oscillator tuning. A programmable fixed value memory (10) stores the preset transmit frequencies, and is interrogated by a clock pulse generator (11) and a counter (12) in such a manner that all stored transmit frequencies appear sequentially during a period of the clock pulse generator at the output (10A) of the memory in a cyclic manner. A frequency counter (17) measures the oscillator (16) generated frequency which also corresponds to the received transmit frequency. A comparator (13) treats the stored and received frequencies and generates a signal, on coincidence, triggering the optical or acoustic display (19). Between the frequency counter and the comparator is pref. incorporated a memory (18), set at the end of each measuring period by the frequency counter generated pulse. It also stores, during the measuring period of the frequency counter, the received transmit frequency.

Patent DE-2949842-A1 (DE)
Title: Monitoring strength of annealed wire - where wire travels round set of rollers using strain gauges for indirect measurement of wire strength and for adjusting annealing temp.
Inventor: KRIEGER JOERG
IPC: G01B7/16
Filed: 1979-12-12
Abstract: The appts. consists of a set of rollers employed to carry the annealed wire along a path consisting of several loops. The path includes two rollers located at the two ends of a measuring beam on which two strain gauges are mounted; and one of the other rollers has an increased dia. so a tensile strain is exerted on the wire. The strain gauges are connected in an electronic circuit which measures the force required to produce the known amt. of strain in the wire. The force is used as an indirect indication of the strength of the wire, and also to adjust the electric current fed through the wire in the annealing process, i.e. electric resistance heating is used for annealing. For example in cable mfg. works, where wire is hard drawn and is then heated so it becomes half-hard or soft. The invention ensures that constant mechanical properties are obtd. in the continuous annealing of the wire. A deflection beam (1) is fitted with two strain gauges (2) and two rollers (7,8), which are located above a pair of coaxial idling rollers (5, 6) mounted on one shaft. Another ther pair (3, 4) of rollers has one (4) with a dia. 5% larger than the dia. of roller (3). The annealed wire travels round the rollers in the sequence (5,7,6,3,8,4); and strain is applied on the wire between rollers (8,4). Gauges (2) are connected in a bridge circuit with a voltage proportional to the stress on beam (1). A potentiometer provides compensation for dynamic measuring errors; and the bridge voltage is used to control the annealing current.

Title: Wort concn. in brewing vat - utilising vapour heat by compressor of vapours for external boiler heating
Inventor: KOREK JOHANNES DIPL ING
IPC: C12C13/02
Filed: 1979-12-12
Abstract: Wort is conc. by evapn. in a brewing vat with an external boiler to which heating steam is supplied from a steam accumulator. A vapour compressor is connected between the vapour space of the vat and the steam supply pipe to the boiler. A non-return valve follows the compressor, and a reducing valve follows the steam accumulator. The brewing vat has an inlet for wort and its outlet leads through a circulating pump to an external boiler. The boiler receives heating steam from a steam accumulator on the steam mains via a reducing valve, controlled by a pressure sensor in the line. This system utilises the heat, recovered from the vapours, for the boiling down process in the brewing vat and provides hot water at a lower temp. for other process purposes.

Title: PABX with rapid number selection - has microprocessor control with working memory storing extension data including free or engaged state
Inventor: CEZANNE LOTHAR ING GRAD
IPC: H04Q3/545
Filed: 1980-01-17
Abstract: The number selection method gives rapid connection between extensions which have very frequently to be in contact. It is applicable to b.p.x.s. using microprocessor control. In a working memory the data relating to each extension are stored, and also the state of the extension, free or engaged. Each extension occupies a defined address within this memory. For the rapid connection between one extension and another the calling extension transmits a special code. This comprises the calling extension number, transmitted by lifting the handset, and a number which, when added to its own address gives the address in the memory for the extension to be called. By arranging also for subtraction of numbers the rapid selection process can be extended in scope.

Title: Locking pawl for telephone dialling switch - has follower pawl on dialling disc, protruding into annular space between ring inner toothing and follower disc
Inventor: HENDEL HORST ING GRAD
IPC: H04M1/31
Filed: 1980-06-07
Abstract: The dialling switch has a follower disc, rotating with it both during selection and the dial resetting run. The disc follower pawl is out of contact with the inner toothing of a concentric toothed rim during dialling, while during resetting run engaging the inner toothing. The outer toothing of the rim drives a pulsing cam disc. The follower pawl (4) is loosely mounted in a recess of the dialling switch disc (2). It protrudes into an annular space between the periphery of the follower disc and the inner toothing (9) of the toothed rim (3). According to the direction of rotation of the follower disc it is pressed against, or lifted from, the inner toothing of the rim. This actuation is carried out by switching cams (6) of the dialling switch disc, mounted concentrically to the follower disc. The switching cams are formed by both ends of an arcuate switching strip, which provides radial guide for the dialling switch disc along the inner toothing of the rim.

Title: Controlling dirty gas flow and removing dust - by clean gas fed tangentially into swirl chamber
Inventor: WEBER EKKEHARD PROF DR ING
IPC: B04C1/00
Filed: 1980-12-03
Abstract: A flow of dust-laden gas is checked and dust is removed by feeding the gas, generally radially, into a swirl chamber into which a clean control gas is fed tangentially at high pressure. The dirty gas is mixed and deflected towards the chamber wall, largely preventing its further access, and dust particles separate under inertia forces. The mixed gases leave the chamber centrally upwards or downwards through a discharge pipe, then entering a dust settlement and extn. container. The control gas is removed and may pass through a cooler, a residual fine dust separator, and a compressor where it is prepd. for recycling through the cleaner. For conditions when the dust makes usual valve devices difficult to operate or shortens their life, and effective for gases at high pressure and temp. e.g. over 1000 deg.C.
