Patent DE-2821413-A1 (DE)
Title: Gasification, by partial oxidn. in free-flow, non-catalytic generator - with sensible heat of gas used to produce superheated steam
Inventor: PAULL PETER L
IPC: C01B3/36
Filed: 1978-05-16
Abstract: Sensible heat is recovered from an effluent gas stream leaving a free-flow, non-catalytic gas generator producing gas mixts. The partial oxidation of a hydrocarbonaceous fuel, a liquid oxygenated hydrocarbonaceous fuel or a slurry of a solid carbonaceous fuel in water or a liquid hydrocarbon. The process is effected in the presence of a free oxygen-contg. gas and opt a temp. moderator at 1500-3500 degrees F and 1-250 atm. The improvement comprises: (1) passing the effluent gas through a first heat exchange zone (A) in indirect heat exchange with steam produced in step (3), thereby converting the steam to superheated steam; (2) removing a continuous stream of superheated steam as byproduct from (A); (3) passing the gas leaving (A) through a second heat exchange zone (B) in indirect heat exchange with water, thereby converting the water to steam; (4) removing raw product gas from (B); and (5) passing at least part of the steam from (B) into (A). The sensible heat in the product gas is used at its maximum temp. to produce superheated steam at a pressure which may exceed the pressure in the gas generator. This steam may be used as dispersant or carrier gas for the fuel feed or as a temp. moderator.

Title: HF welder for plastics articles and/or plastics-coated paper - has bridge switch between tool and generator, with two unified resonators to equalise load fluctuations
Inventor: HOLLE JOHANNES DIPL ING
IPC: B29C65/00
Filed: 1978-06-02
Abstract: Parent patent described H.F. tool for welding thermoplastics mouldings or thermoplastics-coated paper which is supplied by an H.F. generator where an H.F. line has a bridge circuit between generator and welding tool. The bridge circuit shares the power input between 2 equal consuming devices as appropriate, whilst a remaining 4th. switch point is terminated by an absorber. In this addn. both equal consuming devices are H.F. resonators which, whilst sepd. by a partition are combined into 1 single welding tool. Frequency constancy of the generator is ensured by presence of 2 consuming devices (as called for by parent patent) whose power consumption and conditions affecting it are now rendered reliably identical i.e. any variations of the load conform for both consuming devices. Consequently, the generator is independent of any such load fluctuations.

Title: Surface pressure measuring element - is used in patella-femoral joint and includes pressurised line attached to hollow probe
Inventor: SCHMIDT-RAMSIN ECKHARD DR MED
IPC: G01L1/08
Filed: 1978-06-09
Abstract: The pressure-measuring instrument consists of a hollow screw (14) attached to a pipe (2). A T-piece (3) in the pipe allows a pressure-gauge (4) to be connected. A section (5) having a high flow resistance, is formed from a capillary or choke and connects the pipe to a pressure generator (8) via a tap or valve (7). The hollow screw is inserted through the knee-cap and a needle is used to perforate the patella cartilage. The piping etc. is attached to the screw. The system is filled with fluid. A high pressure is established by a pump (8). The valve is then opened so that the pressure rises in the connecting tube only slowly due to the capillary (5). Subsequently the surface pressure in the patello-femoral joint is compensated by the pressure in the screw and the pressure is registered on the gauge.

Title: Fluid level indicator using light conductor - has concave conductor surface regions with bottom end conical or pear-shaped
Inventor: SCHNEIDER WOLFGANG DIPL PHYS D
IPC: G01F23/292
Filed: 1978-10-19
Abstract: A fluid level indicator for containers has a light conductor inserted from above into the container, a light source, and a receiver whose received light gives a level indication. It operates practically independently of the fluid in the container, esp. of the fuel in a fuel tank. The light conductor has a convex surface over at least part of its outer surface. This is achieved using annular projections, grooves, curves, or pref. by using step changes in dia. with each step having sloping edges. The bottom end of the conductor is conical or drop-shaped and is immersed in the fluid. The light flowing through the conductor decreases with deeper immersion since more light escapes at the edges or grooves when they are immersed.
Patent DE-2852658-A1 (DE)
Inventor: WEBER ADOLF DIPL ING
IPC: B22F7/08
Filed: 1978-12-06
Abstract: A process for producing a formed member, and a formed member which includes spherical fragments embedded in a metallic matrix is effected through cold annular or round forming. The spheres are arranged in the interspace between a basic support member, which may be a thin-walled inner casing, and an outer casing. Working of the outer casing causes the material of the support member and the outer casing to be pressed into the spaces between the spheres, densifies the support member and the outer casing, and prestresses the outer casing and spheres, thus allowing the inner casing to be extremely thin-walled. The prestressing of the spheres and outer casing, together with the inner casing imparts a high degree of energy to the casing fragments and to the spheres, affords economies in manufacture and a substantial increase in fragmenting energy at detonation of the formed member.

The bin bears against a support on the discharge side and which is mounted on guides coupled to the arms, so that it rises for part of the way with the latter, and the tipping edge of the bin pivots about the support and the edge of the collector skip.
Patent DE-2909847-A1 (DE)
Title: Position locator for TV monitor of X-ray system - detects position of contact pin on resistance layer and inputs position data via switch in to data acquisition device
Inventor: KNORR DIETER ING GRAD
IPC: G06F3/0354
Filed: 1979-03-13
Abstract: The position locator measures the resistance of the resistance layer to the contact pin and uses it as a measure of the pin's position. The contact pin (2) cooperates with a switch (5) that operates when the pin is pressed down on the resistance layer (1). The switch is connected to the data acquisition device (7) to pass an acquisition command. The contact pin can slide longitudinally in its holder and in so doing operates the switch. The switch is a contactless proximity switch. The advantage lies in avoiding chatter and the interference it causes - i.e. avoids the same point being acquired twice as the pin moves across the layer. The locator can be used with X-ray equipment with television monitor to mark out wanted areas.
