Patent DE-2840842-A1 (DE)
Title: Measuring gas concn. in mixtures - using reaction paper in tape form, monitoring successive intensity difference measurement cycles
Inventor: SCHINKMANN MANFRED DIPL PHYS D
IPC: G01N31/22
Filed: 1978-09-20
Abstract: The concn. of gases or gas components in gas mixtures is determined by reaction paper tapes. When the paper tape reaches a defined brightness difference as a result of the reaction it is moved along and a fresh part is subjected to the gas for a defined time. The brightness difference is then measured and the paper moved on again. The process is repeated until the given intensity change is no longer achieved.

Title: Cassette safety lock for film end - has sprung tag at end of sprocket hole engaged by catch on cassette wall
Inventor: HUJER FRIEDRICH DIPL ING
IPC: G03B17/30
Filed: 1978-09-25
Abstract: The film is provided with a safety sprocket hole which is gripped by a safety catch on the cassette wall to prevent the film from being completely drawn into the take-up spool. The hole is rectangular with a spring tab (13) at one end to act as a buffer onto the sprocket claw to prevent the film from tearing. The tag is formed by two short cuts along the sides of the hole. It provides a damped stop for the film claw. Several holes and claws can be positioned alongside each other for added security.

Title: Fabric treatment chamber - has opposing pair of beltings to carry fabric folds between them
Inventor: CONTI FULVIO
IPC: D06B3/20
Filed: 1978-10-19
Abstract: The processing equipment for washing, desizing, bleaching or shrinking piecegoods, has a character with at least a pair of continuous carrier belts mounted above each other. The main carrier belt supports the fabric, assisted by the other as an auxiliary so that, as they travel together in the same direction, they face each other to create a moving space between them. The fabric is placed in folds on the main carrier and the auxiliary carrier is sufficiently displaced to exert a dynamic grip on the upper ends of the fabric folds. The design gives a multi-purpose equipment which can provide process cycles for a variety of fabric treatments.
Patent DE-2851328-A1 (DE)
Title: Medication ampoule sawing tool - has circular saw band on rim of cup with shank end
Inventor: FRANZES WERNER
IPC: B67B7/92
Filed: 1978-11-28
Abstract: Parent Patent described an ampoule saw for the mechanical opening of ampoules containing drugs. The sawing tool consists of a cup-shaped drum with a shank end which can be pushed into the drive shaft of the motor. A saw blade is attached to the rim of the cup and the bottom of the cup has a central pip which contacts the breaking chamber and prevents the drum from slipping off, causing only little frictional resistance. This eliminates the necessity for a lengthened motor drive shaft and the leaf spring assembly of the saw tool.

Patent DE-2906895-A1 (DE)
Title: Rigid coupling for trailer - has movable wheel mountings for self steering control
Inventor: FALKENHEINER HELMUT
IPC: B62D63/06
Filed: 1979-02-22
Abstract: A rigid coupling between a towing vehicle and a trailer has parallel couplings to prevent any relative steering between the two sections. The trailer wheels are unlocked to self track using a sprung control. This enables the vehicle to be driven as one unit and does not require any steering control for the trailer wheels. The towing system prevents snaking of the trailer, leading to instability. The self tracking wheels can be on a single or a double axle and allow the combined tow to be moved in confined spaces.

Title: Low-voltage high-power fuse - has grip flaps joined by base and held to casing by straps passing around casing
Inventor: SEGER ALBERT
IPC: H01H85/153
Filed: 1979-09-27
Abstract: The fuse has metal grip flaps (1) insulated from the knife contacts fixed to an insulating casing.

The microswitch is operated by the pivoted lever (8) to cause motorised rotation of the knob (9) in one direction until the bistable switch lever (13) is operated by one of the cams.
Patent DE-3006455-A1 (DE)
Title: Plasma separation from healthy donor blood - by membrane of specified pore size and pressure differential
Inventor: NOSE YUKIHIKO
IPC: A61K35/16
Filed: 1980-02-21
Abstract: Plasma is separated from healthy blood by passing it over a filter membrane, made of compatible material with a pore size of 0.1 to 0.6 micron at a velocity of 5-1500 cm/min. The pressure differential above the membrane is kept to within 10-50 mm Hg (20-40 mm Hg). The membrane is either a film or a hollow fibre type, made of hydrophilic material. The inflow blood pump with an inlet from a blood donor supplies a plasma filter bubble trap. The outflow goes through a second bubble trap back to the donor. The plasma is taken to a plasma reservoir and by a plasma pump to a 3-way valve. This directs it either through an absorber cartridge and particle filter back to the donor or to pipe to the plasma treatment. This results in a higher plasma separation efficiency in spite of the lower pressure differential.

Title: Telecine unit using mirror galvanometer scanning - has oil damped scanner with flyback accelerating and braking pulses
Inventor: STEMME OTTO DIPL PHYS DR
IPC: H04N9/11
Filed: 1980-07-01
Abstract: Telecine unit for projecting films and using a bucket brigade CCD photodiode circuit to receive the projected picture for conversion to the TV 50Hz normal field frequency. The design uses an oil damped mirror galvanometer controlled by saw tooth generator circuitry for scanning purposes with an incorporated square wave pulse (17,19) generation for an accelerated flyback signal. The oil damped galvanometer is housed with its mirror turning magnet (4) in the oil reservoir (6) at the base of the housing (1). The magnet sits in the magnet field (M) which produces the sawtooth waveform scanning signal followed by the negative flyback acceleration pulse and the immediate positive braking pulse. The negative and positive acceleration and braking pulses take place in the flyback period between sawtooth waveform scanning pulses.

Title: Gas cooled high temp. reactor having structural side shield - forming pressure boundary to cold gas side to accept pressure difference in fault cases
Inventor: ELTER CLAUS DR
IPC: G21C1/07
Filed: 1980-07-19
Abstract: Gas-cooled, high-temp. reactor (pebble bed reactor) in a pressure vessel vault is connected to a gas turbine unit, circulators etc. housed in the same vessel. The side reflector is supported radially by the thermal side shield through resilient support elements. The annular space between the vault wall and the thermal side shield conducts cold gas delivered by the compressor, and a hot gas line is connected to the space between the bottom plate and bottom reflector, while a warm gas line is connected to the space between the top reflector and top thermal shield. The thermal side shield is a pressure-resistant metal cylinder, connected at its top end to the thermal top shield and at its bottom end to the bottom plate; the annular space outside this shield is completely sealed off from the space contained within the side shield, top shield and bottom plate. Used esp. for a pebble bed reactor, and reduces the pressure-balancing forces that act upon the side reflector during a pressure-balancing fault.

Title: Spark ignition IC engine operation - involves fuel injection into inlet duct and deflected to produce rich mixt. at spark plug electrodes
Inventor: FRANKE KAI
IPC: F02B17/00
Filed: 1980-08-02
Abstract: The arrangement is intended for an i.c. engine having a cylinder (2) with reciprocating piston (3) and a cylinder head (4) with inlet (10) and exhaust valve, a spark plug (9) and a fuel injector (19) with its outlet inside the inlet duct (5,6). The fuel emerging from the injector nozzle (23) is deflected such that it enters the cylinder in the direction of the plug (9) electrodes (27) to produce a rich fuel mixture at that point. This deflection pref. releases the injected fuel at a point (25) as near to the spark plug as possible. A supply line (16,17) for air, with or without an oil-soap emulsion, may have its outlet (18) in the inlet duct adjacent to the inlet valve seat (8) and as far as possible from the spark plug so that the fuel and air flows remain separated.
