Patent DE-2607193-A1 (DE)
Title: Food heat treatment installation - has thermostatically controlled heating elements, centrifugal blower, and air guide channels
Inventor: SCHWAN GERD
IPC: A23L5/10
Filed: 1976-02-23
Abstract: Installation for the heat treatment of foodstuffs using hot air and saturated steam. The hot air or the steam/air mixture are brought to a pre-determined treatment temperature inside a heat insulated container by thermostatically controlled heating elements, and is then circulated by a blower in a closed circuit along two opposite sides of the inner treatment chamber. The heating elements are located inside a chamber sealed against the treatment chamber and open towards the suction side of the centrifugal blower and both lateral air guide channels may be alternately connected with the chamber or with the pressure chamber of the centrifugal blower through openings which may be closed by controlled two way flaps.
Patent DE-2609951-A1 (DE)
Title: Antibiotic susceptibility testing of clinical specimen - transferred to test wells in cartridge holding culture medium and antibiotic
Inventor: GIBSON SANDRA F
IPC: C12M1/20
Filed: 1976-03-08
Abstract: A cartridge contains a number of individual wells linked by passages to a filling port. A clinical specimen is introduced into the filler port and fills the wells which are each provided with an overflow cavity to collect air bubbles during the filling operation. The cartridge is transparent and prior to use a pref. freez-dried culture medium is placed in each well so that microorganism growth within a well can be detected optically. Known quantities of antibiotics are introduced into some of the wells while one well contains no antibiotic. After filling the cartridge with the specimen it is incubated and the wells are examined for growth. The apparatus determines the susceptibility of microorganism to an antibiotic without isolating the microorganism. The culture medium will only support the required microorganism and the effectiveness of the antibiotics is detected by comparing the growths in the antibiotic-free well with the remainder. Determination of the effective antibiotic concentration is faster than previously.
Patent DE-2612824-A1 (DE)
Title: Steam turbine with feed water heater - has auxiliary feed water heater turned on when load is increased
Inventor: ENGELKE WILHELM DIPL ING
IPC: F01K7/40
Filed: 1976-03-25
Abstract: A steam turbine (1) is supplied from a boiler (2). Condensate from the condenser (6) is returned to the boiler through a heater (8) fed with steam (9) bled from the turbine. When the load is increased a controller (13) opens the main steam supply valve (4) and closes the bled steam valve (12). An auxiliary feed water heater (14) with a separate fuel burner (15) is included in the line between the condenser (6) and the main feed water heater (8). Normally the burner (15) of the auxiliary heater is off. When the controller reduces the flow of bled steam to the main heater it also starts the burner of the auxiliary heater. The temp of the boiler feed water is thus maintained even with reduced steam flow.

Title: Rotary mixer esp. for chipboard prodn. - has glue feed nozzles supplied from distributor head to equalise distribution
Inventor: LOEDIGE WILHELM
IPC: B01F7/02
Filed: 1976-06-10
Abstract: Appts. for mixing liquids with powdery, fibrous and/or chip-like substances, esp. for mixing glue with wood fibres or chips for the prodn. of fibre-board or chipboard, comprises a stationary mixing drum with a coaxial rotor, the glue being intoruced through a number of nozzle pipes mounted in the stationary wall of the drum, supplied in groups from a single feed pipe.

Title: Weighing platform for stationary or moving vehicles - has low profile castellated section flexure member bearing strain gauges
Inventor: BROSA ERICH
IPC: G01L1/22
Filed: 1976-12-04
Abstract: The platform is suitable for weighing stationary and moving vehicles and consists of a flexure member mounted between two flat plates (14). The flexure member is of castellated cross-section comprising a series of pairs of rib-like projections on opposite faces.

The heights of the ribs alternate presenting a wave-like profile. Electromechanical transducers, which may be coils (11) or resistive strain gauges are mounted in the grooves between the ridges. An applied load causes bowing of the flexure member which is measured by means of the transducers. The platform may be constructed in rectangular or circular form.

Title: Rotary printing press inker - has relatively large return ports to drain off foam
Inventor: BRANDT ECKHARD
IPC: B41F31/06
Filed: 1976-12-18
Abstract: Inking appts. for rotary printing press has an ink duct (1) and a duct roller (4) engaging the ink. The duct has an inlet port (3) for fresh ink and a return port (14, 16) for excess ink. To cope with foam, the flow area of the return port is several times > the inlet port. Pref. there are two return ports, one near each end of the roller. This meets the way in which the ink, and thus the foam, tends to circulate in the duct under the influence of the roller. The return ports may be at the bottom of a weir.

Title: Linearisation circuit for resistance thermometers and thermocouples - uses squarer with weighting factor and differential amplifier
Inventor: KLEMPFNER FRANZ DIPL ING
IPC: G01K7/14
Filed: 1977-03-12
Abstract: The linearization circuit is used for correcting the non-linear characteristics of measuring transducers, esp. resistance thermometers and thermocouples. It provides simple matching to transducers having different characteristic curve shapes. The output signal from the probe (1) is fed to two different channels. One channel is directly connected to the non-inverting input of a differential amplifier (7). The second channel comprises a squarer stage (4) followed by a circuit (5) in which a weighting factor is applied. A switch (6) connects the weighted, squared signal either to the inverting or non-inverting input of the differential amplifier. At the output of the amplifier, a signal appears in the form Ua = Uo (+-) KUo2 in which the special weighting factor for each transducer and measuring range gives a practically linear relationship between Ua and the measured value.

Title: Tension measurement for metal strip - uses strut fixed between feed and driving rollers to straighten strip (OE 15.8.77)
IPC: B21D1/05
Filed: 1977-05-13
Abstract: To straighten the metal strip (2) it is passed between the straightening rollers (1) which are arranged to bend the strip alternately in opposite directions. The strip (2) is drawn from the feed rollers (5) mounted in the frame (3) by the drive rollers (5) mounted in the frame (4). The frames are mounted at their lower inner edges on pivots (8). The upper parts of the frames are connected by a strut (6). The tension in the strip (2) creates a proportional compressive force in the strut (6) which is measured by a sensor (7). The magnitude of this compressive force indicates the average tension in the strip (2).
Patent DE-2734255-A1 (DE)
Title: End buffer assembly for gas flowmeter sight tubes - uses rectangular elastic insert e.g. of rubber, on at least one end of transparent tube
Inventor: MARQUARDT KARL
IPC: G01F1/22
Filed: 1977-07-29
Abstract: The flowmeter comprises a transparent glass tube (1) such as used in float-type flowmeters. At the upper end of the tube is a rectangular, pliable buffer (2) made of rubber or similar elastic material. The buffer is a friction fit in the tube so that it remains in place. Additional security may be obtained by the use of adhesive. The size and shape of the buffer is chosen so that the gas can flow easily through the tube. The tube may also be of plastics material as an alternative to glass. A second, identical elastic buffer is placed at the bottom, inlet and of the sight glass so that it has the same energy-absorbing, cushioning effect on the floating indicator when large fluctuations in the gas flow occur. This construction prevents jamming of the float as can occur with types of flowmeter using spiral spring buffers.
