Title: Vacuum-evapn. heater - has outlet which selectively allows diffusion of non-condensable gases to atmos. retaining vapour
Inventor: YAMADA SADAKAZU
IPC: F24H1/00
Filed: 1975-03-18
Abstract: In a heat exchanger using the vacuum evapn. principle to heat one or more media in sep. pipe coils in a common evacuated vessel partially filled with a vaporisable liq. the upper space inside the vessel is connected to a sep. chamber which is sealed against the atmos. by a film of polymer material permeable w.r.t. non-condensible gases.

Title: Amplitude adjustment for geophone output signals - signal derived from each geophone in group generated by background noise
Inventor: SAUNDERS DON A
IPC: G01V1/16
Filed: 1975-05-02
Abstract: The amplitude adjustment takes into consideration changes of energy transmission due to the nature of the ground under the geophones. A signal is derived from each geophone, generated by background noises, and compared with a reference signal. Geophone outputs are adjusted in accordance with the ratio of the noise to reference signals, so that output signals generated by seismic energy in each geophone accurately represent the seismic energy which reaches the surface layer under the geophone. Unwanted or irrelevant frequencies are removed by filters before the amplifying stages. An average value for all the processed signals can be easily achieved if desirable.

Title: Double piston shut off valve - has latch for holding spring biased piston back to block passageway
Inventor: TUCHENHAGEN OTTO
IPC: F16K25/02
Filed: 1975-05-26
Abstract: The shut-off valve with leakdage control comprises a cylindrical valve passage (4) opened when two pistons (5, 6), normally closing the passage, are pushout of the passage by an axial force on a rod connected to one of the pistons. The other piston has a leakage drain to atmosphere which is closed when the pistons abut at the commencement of the opening movement of the piston. The rod is normally held in the retracted position by a latch so that fluid pressure on the piston cannot inadvertently open the valve. Only one of the pistons need have sealing engagement with the cylinder.

Title: Computer controlled exchange data transmission control - uses standby control keeping sync. counters working during failure
Inventor: PREY GERHARD
IPC: H04L7/00
Filed: 1975-08-29
Abstract: The synchronous data transmission control, for computer-controlled exchanges, avoids loss of synchronisation as a result of interference or failure by using a standby control to take over during this faulty period. The standby control takes over the processing of data for transmission from the original processing device only during a failure. But the counting units (bit, character and block counters). The synchronisation of the counting units at the transmitter is maintained and monitored by the exchange of signals denoting the beginning or end of transmitted frames.

Title: Generation of signal dependent on object distance - uses luminous source to obtain image with electrical sound conversion
Inventor: WITTE WOLFGANG DIPL PHYS DR
IPC: G01B11/14
Filed: 1975-09-27
Abstract: A signal is generated depending on the distance of an object from the detector. The object is considered as a distant object in an optical system used for such purposes as orientation by blind persons or for automatically tracking a a cinematographic camera. A lens (12) forms an image of a distant object and then a second image (10) is formed. Between this second image (10) and lens is a beam splitting screen (20) whose image is formed in the distant object. The second image (10) is illuminated by a light source (24) through an inclined semitransparent mirror (26) and condenser lens (28). Light from the distant object passing through the second image (10) is reflected by the mirror onto a radiation detector (38) to which an amplifier (40) and loudspeaker (42) are connected. Movement produces a tone.

Title: Garment insulation mfr. - incorporating air chambers between inner and outer layers to increase fabric life and improve waterproof effect
Inventor: KLEIN HANS
IPC: D06N7/00
Filed: 1975-11-29
Abstract: A flexible insulating material, partic. for anoraks and other garments is mfd. composed of a number of layers. The layers are of an outer permeable woven fabric, a woven lining and an intermediate layer formed from a wadding with a needled metal foil. Two air chambers are located between the intermediate layer and the outer fabric. The air chambers are sepd. by an insert of a fibrous non-woven material. The metal foil of the intermediate layer is placed on the wadding on the side facing the non-woven and the lining of the outer fabric. The provision of the air chambers increases the thermal reflection of the insulating layer and also prevents the insulating layer from becoming wet when worn in rain, so that distortions and abrasion are not experienced and increase the fabric life.

Title: Hydro mechanical antiskid brake - uses brake reaction force to generate repetitive brake pulses to floating piston pressure control
Inventor: OTT BERND ING GRAD
IPC: B60T8/52
Filed: 1976-03-01
Abstract: The hydro-mechanical anti-blocking brake has the brake cylinder in a sliding mounting so that it can be displaced slightly by the brake reaction. A pressure control valve has two floating pistons, with one piston pressing against the side of the wheel cylinder so that the wheel cylinder is pressed in the other direction by the brake pressure. The second floating piston has a fluid duct to control the flow of fluid to the brake cylinder. In the heavy braking mode the brake reaction force on the first piston presses the second piston to a position where the flow of fluid is maintained as long as there is braking reaction. When the wheels start to lock and the brake reaction force drops, the piston pushes the brake cylinder to one side and at the same time cuts off the brake line.
