Patent DE-3010343-A1 (DE)
Title: Combustion gas heat recovery process - cools gases from boiler to below ambient temp. before passing into chimney
Inventor: POEHLMANN ERICH
IPC: F28D21/00
Filed: 1980-03-18
Abstract: The process recovers heat from combustion gases by means of a heat pump system, the latter incorporating a heater, an evaporator and a heat exchanger. The gases from a direct-fired boiler acting as the heater are first cooled to below ambient temp. before passing into the chimney, being then reheated to ambient temperature by the heat of the environment. Two heat exchangers can be used, the first extracting part of the heat from the gases and transferring it to the return pipe in the water heating system. The second is supplied with the evaporated refrigerating medium, and cools the gases nearly to evaporation temperature.
Patent DE-3018698-A1 (DE)
Title: Three=dimensional TV system - employs vertical scanning and CRT overlay sheet incorporating vertical prismatic serration lines
Inventor: HILF PAUL
IPC: H04N13/00
Filed: 1980-05-16
Abstract: Two-dimensional t.v is converted into three-dimensional vision using the same principle as printed postcards having an overlay of a plastics sheet whose surface consists of a large number of vertically serrated prismatic lines. Each 'line' is in effect a prism with a base width of a fraction of a millimeter accurately covering two neighbouring vertical printing lines. The left slanted side of the prism, and therefore also the left printing line, can only be seen by the left eye, the right slanted printing line, can only be seen by the left eye, the right slanted prism side, and therefore also the right printing line of the pair, by the right eye. By producing the pairs of printing lines from pictures gives a genuine three-dimensional impression. An overlay of a similar plastics sheet grated by vertical prism lines on a t.v tube screen could provide three- dimensional t.v. The only adaptations required would be the conversion from horizontal to vertical scanning in receivers and cameras, and cameras would have two optical systems instead of one.

Title: Extending the life of shortening for deep frying - using a heat-expanded pumicite particulate as filter aid to remove fatty acids
Inventor: COHEN MARVIN DAVID
IPC: B01D37/02
Filed: 1980-05-30
Abstract: The life of shortening (I) is extended as follows: (a) a filter aid (II) is added to the vat of shortening; (b) the (II) particles are circulated and dispersed in (I); (c) the shortening and the contd. (II) are circulated and passed through a filter. (II) is a heat-expanded pumicite particulate contg. 80 % SiO2, ca 2% Fe2O3, =3% H2O, ca 3% MgO and trace amts. SO2, and is expanded as in US3996158 to density 4.8-61lb/ft3. (II) are extremely effective as single-pass filter aids in the extrn. of satd. fatty acids from (I). The method reduces the cost of frying with (I) and also prevents the development of burned or rancid taste in food fried in treated oil.

Title: Convertible chair bed with seat and two-part backrest - has triangular articulated rods automatically moving parts into position without adjusting cushions
Inventor: SCHEFTHALTER ALOIS
IPC: A47C17/165
Filed: 1980-06-27
Abstract: The seat part (1) is connected to the front (2) and rear (3) parts of the back rest by a tubular hoop (11,10) in the manner of an articulated triangle (6,7,8) with the seat element (1) being guided by a moving carriage (5) which is supported on the base frame (4) so that when the seat element is pulled out it automatically extends the front part of the back rest whilst at the same time bringing the rear part via a double joint (7) into the flat bed position. The cushions can now remain fixed in position on the seat and two part backrest and the entire conversion operation can be carried out in one step. This is further facilitated if rollers are mounted on the guide carriage and side parts of the seat element.

Title: Body function frequency measuring appts. esp. for breathing rate - determines quotient of measured to reference count values using programmable memory and binary counters
Inventor: SEGERSTAD CHRISTER HAARD AF DI
IPC: A61B5/04
Filed: 1980-07-24
Abstract: The circuit is for measuring the frequency of a periodic signal and is esp. applicable to bodily functions such as breathing. The conventional method of counting breaths over a period of half to one minute is automated simply. The number of pulses derived from a signal corresp. to the function is fed to a programmable memory with a number of reference pulses. The quotient of the measured reference pulse counts is digitally determined. The derived and reference pulses are fed to binary counters whose output values are fed as addresses to the programmable memory or memories at defined times. The transfer times are determined by a decoder. At these times the count values are first input to intermediate memories and converted into addresses before transfer to the programmable memories.

Patent DE-3044438-A1 (DE)
Title: Data modem baseband converter and monitor - injects control frequency over carrier section to monitor and compensate for frequency deviations etc.
Inventor: GRUENES REINHARD
IPC: H04H20/67
Filed: 1980-11-26
Abstract: As the audio band for radio is 0.3 to 3.0kHz and that for carrier 0.3 to 3.4kHz the method uses two auxiliary frequencies, 3.2 and 3.4kHz typically, in the 3.0 to 3.4kHz band. Incoming data from a source (GW-Zentrale) are fed through a low-pass filter and into an adder stage where the auxiliary frequencies from an oscillator source are combined. The frequencies are derived by frequency division. The combined signal is then transmitted over the carrier section. On the carrier output is a low pass filter and multiplier stage controlled by an oscillator. The auxiliary frequencies are fed through a high pass filter for rectification and phase comparison which provides compensation control to the v.c.o. which controls the output signal at the second multiplier stage. The second multiplier is used to transpose the original signal into the audio band and to apply correction as fed to the v.c.o. from the phase comparator circuit.

Title: Energy recovery from in-situ retorting by-prod. gas - involving partial combustion by catalytic oxidn.
Inventor: ACHESON WILLARD PHILLIP
IPC: F23R3/40
Filed: 1980-12-15
Abstract: Method of recovering energy from low-heating-value (LHV) gas obtd. as a by-prod. during an in-situ combustion process for recovery of oil from a subterranean formation comprises (a) preheating the LHV gas, (b) mixing the gas with air, (c) oxidising the combustible components of the mixt. by contact with an oxidn. catalyst, and (d) generating energy from the hot combustion prods. The gas in (a) is preheated to a temp. such that the mixt. formed in (b) has a temp. of 204-427 deg.C, and the amt. of air used in (b) is less than the stoichiometric equiv. of the combustible components in the LHV gas and is insufficient to produce a temp. rise which would damage the catalyst in (c). The method is esp. applicable to LHV gases (e.g. from in-situ retorting of oil shale) whose pressure and heating value are too low for combustion in flame-type burners.

With this system only air-free milk or milk of low air content can enter the measuring chamber.
Patent DE-3116510-A1 (DE)
Title: DC voltage starting for gas-discharge tubes
Inventor: PRINZ FRANZ JOSEF
IPC: H05B41/04
Filed: 1981-04-25
Abstract: The invention relates to a starter circuit for gas-discharge tubes, preferably fluorescent lamps, which makes possible an operating function without the known incandescent electrodes and without any starter (glow-light thermal switch). The starting voltage for gas-discharge tubes is produced, according to the invention, by a stable-current bridge rectifier and by an additional current-limiting voltage cascade which converts the operating AC voltage of, for example, 220 volts, until the start of the gas discharge (ignition) by a multiple into a DC voltage which is reduced once again to the operating value of the fluorescent lamp once starting has been completed. In comparison with the generally known starting method, the starting circuit offers the following significant advantages:   1) No starting delay caused by the heating-up time of the incandescent electrodes and the starter, as well as the possibility of starting repetition (flashing). 2) The light intensity of the fluorescent lamp can be regulated by a series resistor or by a semiconductor, to enable so-called effect lighting systems using fluorescent lamps. 3) The fluorescent lamps according to the invention do not need any incandescent electrodes and these can be replaced cost-effectively by so-called flat electrodes. 4) The starting circuit and the ballast inductor which is required can be integrated in the ballast unit. 5) Series circuits comprising a plurality of fluorescent lamps are possible using only one ballast unit.   <IMAGE>

Title: Fusible conductor for a fuse device and method of producing it
Inventor: SCHULTZ LUDWIG DR
IPC: H01H85/055
Filed: 1981-12-02
Abstract: A fusible conductor for a fuse device, in particular for a semiconductor fuse, comprises a plurality of fibres composed of nobler metal in at least one narrow region. Its regions outside said narrow region contain parts composed of baser metal. In order to be able to produce such a fusible conductor relatively simply and cheaply, with only a relatively small proportion of the nobler metal being necessary, the invention provides for the fusible conductor (16) to contain continuous fibres (4 to 9) composed of the nobler metal and for its regions (17) outside the at least one narrow region (18) to be formed from a fibrous composite material containing the fibres (4 to 9) and a matrix (3) surrounding the fibres (4 to 9) and composed of the at least one baser metal. Advantageously, the matrix (3) composed of the baser metal of this fusible conductor (16), which may be, in particular, in strip form, can be surrounded in a form-fitting manner by a cladding (10) of a scale-resistant material.   <IMAGE>

Title: Device for regulating the pulling force in the lower links of a tractor lifting mechanism
Inventor: STEPRATH WERNER ING GRAD
IPC: A01B63/112
Filed: 1982-04-02
Abstract: What is proposed is a device (10) for regulating the pulling force on a tractor (11) having an articulated plough (15), in which the two lower links (13, 14) are mounted on the tractor housing (37) via a bending bar (36), the two bearing points (38, 39) of which absorb the sliding movement occurring as a result of the shortening of the deformed bending bar. The bending bar (36) is mounted at each bearing point (38, 39) by means of a bolt (45), these being parallel to one another and forming pivot axles (45) which extend vertically in the tractor (11) and which are at a short distance from the longitudinal axis of the bending bar (36). As a result of the eccentric position of the bolt and its play, the sliding movement is absorbed, so that the device works with low hysteresis, even where large strokes of the bending bar (36) are concerned, and is also of compact and robust construction. <IMAGE>

Title: Control method and controller circuit for a variable-amplitude input signal
Inventor: HAUSER FRANZ
IPC: H03G3/20
Filed: 1982-06-02
Abstract: A control method is specified in which the amplitude-controlled input signal is rectified in order to generate a first signal which is integrated in order to generate a second signal, representing the envelope curve of the first signal, which is then compared with the first signal in order to generate pulses when the first signal exceeds the second signal. These pulses are integrated for generating a stairstep-shaped third signal which is then compared with the second signal in order to generate a gain increase pulse increasing the gain factor for the input signal when the third signal exceeds the second signal. In addition, the controlled input signal is compared with a particular upper threshold in order to generate a gain decrease pulse decreasing the gain factor whenever the input signal exceeds this threshold value, these gain decrease pulses being generated with a clock frequency which is very high compared with the frequency of the input signal. <IMAGE>

Patent DE-3226220-A1 (DE)
Title: Mould and process for manufacturing conical masts from glass fibre-reinforced plastic
Inventor: CRONENBERG DIETER-JULIUS
IPC: B29C70/20
Filed: 1982-07-14
Abstract: A steel tube (core 30) of a mould, which is surrounded by a flexible rubber tube (34), is wound with glass fibre mats (36), introduced into an outer tube (20) of the mould and closed at its end. The complete mould is suspended vertically with the larger diameter downwards. Liquid plastic is injected from below into the annular space between the core and outer tube, limited to the volume required for the mast, generally making up a quarter to a third of the pipe height. Then the inner tube is filled from below with a liquid, which is then pressurised. The liquid pressure acts on the flexible tube via openings (31) in the lower area of the inner tube, so that this flexible tube lifts up and presses the glass fibre mats into the outer mould. With a further increase of pressure in the core the flexible tube is lifted over the complete mould, causing the liquid plastic to rise in the annular space until it overflows. After curing of the plastic the liquid is drained from the core, so that the flexible tube again presses on the core. After disassembly of the mould the finished mast can be removed. <IMAGE>
