Patent DE-2437060-A1 (DE)
Title: Anti skid brake control - uses smaller three way valve to control large flow main valve for heavy vehicle
Inventor: KIRSTEIN LOTHAR ING GRAD
IPC: B60T8/36
Filed: 1974-08-01
Abstract: A three position electromagnetic control valve provides three operations for the brakes; increase of brake pressure, constant brake pressure and decrease of brake pressure. Such valves have a limited throughput and are usually used on vehicles with a small braking system. The invention provides a similar brake control for a large braking system in which the three way control valve acts as a control to a larger volume flow valve. The control valve regulates the setting of the large volume piston so that a large fluid throughput can be regulated with a fine degree of control.

Title: Process for applying liquid composition to strips - varies pressure difference between sides of sheet formed from strip
Inventor: FOWBLE WILLIAM FRANKLIN
IPC: B29C48/07
Filed: 1974-11-13
Abstract: The liquid is spread over a continuously moving strip, to which items are stuck, by forming a sheet of the liquid by means of a layering device mounted near the strip path, the sheet being maintained between the device and the strip so that it does not move in the direction of travel of the latter. This is achieved by applying gas pressure to the upstream face of the sheet which is lower than a pressure acting on the downstream face. The difference between the two pressures is increased until just before an item reaches the sheet, and then held constant while the item passes across it. The difference is then reduced to the initial value again.

Title: Homogenizing butter and whipped cream consistency - by sudden brief vacuum treatment between pasteurization and cooling
IPC: A23C13/12
Filed: 1975-01-15
Abstract: The consistency and spreadability of butter and whipped cream can be optimized by applying a brief vacuum to the cream, which is used as the raw material, immediately after pasteurization by heating and before the subsequent cooling process. A vacuum of 20-50 (35) cm Hg is applied quickly for 20 sec. This reduces the hardness of winter butter and increases the hardness of a summer butter, in both cases to the medium-hard value on the MOHR scale.

Title: Dart type supersonic VTOL aircraft - with pivotted engine above wing to eliminate hot gas recirculation when hovering
Inventor: DZIALLAS DIETRICH
IPC: B64C29/00
Filed: 1975-06-20
Abstract: The supersonic VTOL aircraft has the main drive engine (5) mounted on a pylon above the wing (1). The engine can pivot to direct the thrust downwards, through a cutout slot (7) in the wing.

Title: Portable battery operated optical reader for product codes - reads strip coded binary data from labels using hand held optical probe
Inventor: HESTER GERALD
IPC: G06K7/10
Filed: 1975-08-22
Abstract: The optical reader for data-handling installations can be used with the Universal Product Code marking system employed in stores and supermarkets for the rapid registration of large numbers of goods.

A l.e.d. is used to illuminate the strips and a photo-transistor transducer converts the reflected light to electrical signals. An interface circuit (13) automatically energises the light source in a cyclic manner to conserve battery power and to ensure that only correctly-read data is registered in the memory. A microprocessor 'chip' can be used for controlling the code read-out and verification sequences.

Title: Three point power transmission chain - has load transmission pins spaced from locating pins
Inventor: WEICHELT KARL-GUENTER
IPC: F16G13/06
Filed: 1976-02-25
Abstract: The links of a power transmission chain have two separate rows of pins. One set of pins pass through holes in the ends of the adjacent links and transmit the load. A second set of pins pass through bushes arranged at the mid point of the inner edge of each link. The pins at the ends of the links transmit the load. The pins at the midpoints of the links engage the teeth of the chain wheels. The load bearing pins are thus not subjected to wear as is the case with the inner row of pins which engage the chain wheel teeth.
