Title: Pastry trimming template - made of throwaway or edible material to save cleaning after use
Inventor: SONDERMANN KARL
IPC: A21C15/00
Filed: 1977-05-06
Abstract: The Parent Patent No. 2640983 described a template with a variety of geometrical cut-outs which can be used even by unskilled personnel to trim fancy cakes and pastry. These templates are too bulky for dish washing machines and must be cleaned by hand after use. This can be saved if the templates are designed as throwaway articles. They can be made, for example, of paper, parchment, plastic foil, hydrate-cellulose foil or aluminium foil. Other possible materials are of the edible type like the material from which wafers are made.

Title: Rapid hydrothermal prodn. of zeolite A for use in detergents - by reacting active silica with aq. alkaline sodium aluminate soln.
Inventor: CHERDRON EGON DIPL CHEM DR
IPC: C01B39/14
Filed: 1977-05-18
Abstract: Active silica is stirred with an aq. soln. contg. Na aluminate and NaOH, esp. Na aluminate liquor from the Bayer process. The zeolite formed is converted into crystalline zeolite in >=2 hrs. at >85 degrees C and opt. washed with water after filtration.

Title: Liq. flow monitor with constant head chamber - has pressure transducing diaphragm controlling output valve in accordance with liq. level fluctuations between preset thresholds
Inventor: THEDIECK REINER DIPL PHYS
IPC: G01F3/36
Filed: 1977-07-20
Abstract: A fluid flow device for monitoring the parameters of a flowing liquid includes a chamber (15) into which the liquid enters via an input (5). A diaphragm (29) transmits pressure signals to a control box (25) indicative of the level of liquid inside chamber (15) above the diaphragm level. In the base of chamber (15) a reciprocating valve unit (28) is provided whereby fluid may be released into a secondary chamber (10) to output (7). A fall in fluid level below a preset level (40) causes the control unit to actuate valve (28) to close on its seat (11) whereas a rise in fluid level above higher preset level (41) initiates opening of the valve.

Patent DE-2837924-A1 (DE)
Inventor: HOETGER KARL
IPC: B31B100/00
Filed: 1978-08-31
Abstract: The tubular boxes are delivered as a stack into a container (12) and are supported in this by extensions (30). The particular bottommost tubular box (28) is grasped on one of its lower surface portions (a) by suckers (47) and drawn downwards out of the container (12). The suckers (47) are arranged in a bearing plate (46), beyond the edge of which project freely the two surface portions (c, d) of the tubular box (28) which lie one on the other and which are not grasped by the suckers (47). These surface portions (c, d) are then bent downwards by a batten (39) as a result of the lifting of the bearing plate (46) and are slightly deformed permanently. The bearing plate (46) is thereafter lowered, in order to erect the tubular box (28) against an angle iron (45), and is then displaced horizontally, in order to deform the tubular box (28) by means of a roller (44) into the opposite position lying flat, from which the tubular box, after being released, automatically erects itself elastically. Even tubular boxes of lower quality, which have large production tolerances and which are possibly distorted, can consequently be reliably erected mechanically. <IMAGE>

Title: Delay circuit for railway signalling systems - has clock-controlled shift registers in loop-circuit, which produce output signal within set delay time after being triggered
Inventor: KOPPERSCHMIDT GERD DIPL ING
IPC: B61L7/08
Filed: 1978-09-28
Abstract: The delay circuit produces an output signal within a required time after the appearance of a trigger pulse. To keep the number of components to a min. the circuit employs two clock-controlled shift registers with a given number of stages in the loop circuit. When a trigger pulse appears only one register stage in each shift register is set into a given binary state. The output signals of the shift registers are processed in a logic circuit that controls a bistable flipflop.

Patent DE-2906981-A1 (DE)
Title: Taking samples from bi-directional flow - has pressure differential which operates valve to divert flow into sampler, weighs sample, and measures pressure balance
Inventor: ROETHELE STEPHAN DIPL ING
IPC: G01N1/20
Filed: 1979-02-22
Abstract: Flow goes both in and out of the measurement probe (1). The static pressures on the inside of the probe and on the outside of the probe are both monitored and connected to a pressure balance (8). When the flow velocity increases in one direction or the other, the pressure inside the probe increases or decreases. This unbalance is used to operate a regulator (5) which diverts the flow via the sample chamber (4). The weight of the sample in the chamber is measured and the displacement of the pressure balance may be measured photo-electrically. These factors can also be used to control the sampling.
Patent DE-2917041-A1 (DE)
Title: Profiling and perforation of hard and soft films - by compressed air instead of vacuum deep drawing
Inventor: FRENKEL WALTER
IPC: B26F1/24
Filed: 1979-04-27
Abstract: The cooling operation necessary after hard and soft, plasticised synthetic films have been profiled and performated by deep-drawing against a needle bed, for the production of mats for air bubble massage baths, is eliminated. The plasticised mat or film is forced against the needle bed by compressed air immediately, to bring about the profiling and the perforation with automatic simultaneous cooling.
Patent DE-2918813-A1 (DE)
Title: Bending machine for metal bars or tubes - has horizontally movable pillars supporting respective anvils on which workpiece is bent via rollers on lever arms
Inventor: KRAUSE ERWIN
IPC: B21D7/022
Filed: 1979-05-10
Abstract: On the machine bed are two pillars which can be moved horizontally towards or away from each other to suit the length of the workpiece, e.g. a metal bar; and each pillar supports an anvil on which the bar rests. Above each anvil is a roller forming a bending die, and a lever moving another roller to bend the bar round the die. In the space between the two pillars is a clamp used either to hold the bar or to rotate it through a desired angle. Useful in the automatic mfr. of antiroll bars for cars. Each pillar (27) supports anvil (11) on which bar (12) rests. Two work cylinders (14) each move a lever arm (15) carrying a bending roller (16), which bends bar (12) onto roller die (32) so two bends are made simultaneously or successively. Clamp (13) includes a pneumatic cylinder (45) pressing two clamping rollers (42) against bar (12), but the clamping pressure can be partly released so a hand lever can rotate bar (12) through a desired angle between bending operations.
