Title: Hand held temp. contact sensor - has compression spring in handle to maintain constant force for reproducible results
Inventor: HONIGMANN GUENTER
IPC: G01K1/16
Filed: 1976-09-22
Abstract: A hand-held temp. contact sensor for measurement of surface temp. of heating devices in textile machines is developed to produce reproducible measurement results independent of the individual operator's method of application. This requires that the sensor is always applied with the same force and the force must be sufficient to produce good thermal contact. It consists of a handle (1) with a sensing head (2) at one end which can move w.r.t. it. Between the head and handle is a spring (24) controlling the application force and the head is connected to a temp. sensor (8, 9). For better application force regulation a further plane spring (31) is fitted to the head.

Title: Flap valve with noise suppressing auxiliary closure - has louvre of pivotal vanes downstream of flap biassed shut by own weight
Inventor: ANSPACH EDUARD
IPC: F16K15/03
Filed: 1977-04-06
Abstract: The flap valve has, downstream of the flap (1), a louvre of pivotal vanes (3). When the flow through the valve reverses and the flap consequently closes, the vanes tend to close first. This reduces the force on the flap and suppresses noise on closing. Both the flap and the vanes are biased gravitationally into the closed position. The vanes are light sheet metal members and tend to close in advance of ther elatively heavy flap. The flap and vanes may be arranged in a common housing.

Title: Fuel injection volume limiting valve for supercharged engines - has accelerator pedal with compressed air cylinder to modify valve pressure
Inventor: BERGMANN HORST ING GRAD
IPC: F02D1/14
Filed: 1977-04-27
Abstract: The super charged compression ignition engine has a charging pressure dependent valve to reduce the fuel injection volume at acceleration phases in order to keep within the proposed air pollution regulations. The valve is a sprung diaphragm (5) whose movements are transferred by a toggle lever (8) to the injector pump regulator lever (9). The accelerator pedal is connected to the piston of a comparatively large air compression cylinder (14). Accelerator pedal movement can push air to atmos. via a restrictor (15) and to the pressure reduction valve feed pipe (1a) via a non return valve (16). A sudden movement of the acceleration pedal causes the non return valve (16) to open causing air from the cylinder (14) to act on the sprung diaphragm (5) to reduce the fuel injection volume.

Title: Stackable plastics box container - reinforced by side and bottom ribs to resist bulging under pressure of contents
Inventor: PROEDEL ULRICH
IPC: B65D21/02
Filed: 1977-05-27
Abstract: Plastics, single-piece, storage and shipping box containers, especially for highly viscous prods. e.g. very soft cheese or dough for bread-making, comprises ribbed bottom and walls, the latter being double and downwardly hollow at the corners of the container. The ribs of the bottom have a re-entry step where they pass over into the walls, which bears upon the top edge of the walls of a container underneath it when the containers are stacked one on top of the other. This causes the bottom (ribs) of the superposed container to fit into the one under it. The walls have, at their outside edge, a downwards protruding rib which, together with the re-entry step, defines a 'U'-profile which is open downwards and whose dia. is sufficiently great that it overlaps the width of the top edge of a container stacked underneath it. The box container, is resistant to deformation (bulging) under the wt. and pressure of its viscous contents.

Title: Decaffeination of coffee - by selective extraction of caffeine with solvent under high pressure
Inventor: PETER SIEGRIED PROF DR
IPC: A23F5/20
Filed: 1977-08-22
Abstract: Decaffeination of coffee by extraction with a solvent is improved by applying high pressure (50-1000, pref. 100-500 atmos); the temp. is 20-70 (pref. 35-50 degrees C. This method is suitable for the removed of caffeine from raw coffee (after disintegration with water vapour at elevated temp.), or from roasted coffee, or from aq. extracts of coffee. The application of high pressure increases the extraction rate and the solubility of caffeine in the solvent. Therefore, there is no need for applying high temps.; 45 degrees C is enough.
