Patent DE-1922779-A1 (DE)
Title: Evaporating natural gas - by combining evaporator with condensation turbine of power station
Inventor: GERHARD LINDE DR-ING DIPL-PHYS
IPC: F17C9/04
Filed: 1969-05-05
Abstract: Low-boiling liquids such as natural gas are evaporated by heat-exchange with a condensable refrigerating medium (e.g. C3H8) which has a critical temp. >0 degree C, the pressure of the condensed refrigerating medium being increased to a value corresponding with its vapour pressure at 0 degree C. The refrigerating medium is evaporated at high pressure in heat-exchange with the exhaust stream of a condensation turbine in a power station, and subsequently condensed again at low pressure in heat-exchange with the evaporating low-boiling liquid.

The purpose is to provide an edge which can be attached to knitted or woven fabrics, non-wovens or leather by sewing, adhesion or heat fixing.
Patent DE-2121698-A1 (DE)
Title: Producing toroidal segments - of large size
IPC: B21C37/28
Filed: 1971-05-03
Abstract: Toroidal segments are cut from complete toroids that are made from separate shaped plates, formed by rolling or pressing, and then welded together along the circumferential seams. It is normal practice to make such segments individually, in which case the segment, when completed, has to have closure plates welded on each end so that it can be pressure tested. These plates have to be cut off, which leads to wastage of both time and material. In the new method, pressure testing of the complete toroid takes placce, and the only wastage is the width of the cut used to part off the required length.

Title: Closure flange seals - for radio-active materials transportable container
Inventor: COLHOUN CHRISTIAN
IPC: G21F5/12
Filed: 1972-12-08
Abstract: Vessel closure seal construction esp. for transport containers for dangerous, fissile or radio-active materials, comprises a combination of elastic rubber and low m.pt. metallic 'O'-rings used in flange face and circumferential locations. The outer rubber 'O'-rings normally sustain vessel joint effectiveness =300 degrees C with the metal 'O'-rings melting > this temp. to maintain joint integrity. The parallel grooves for the metal 'O'-rings incorporate peripheral mating tapered sections forming a conical void to absorb, by capillary action, excess liq. metal. The system conforms to requirements for the safe transport of radioactive materials and offers economy in construction with adaptability to closure and vessel flange dimensional standardisation to suit a range of varying vessel sizes.

Title: Improving contact between recording medium and pressure stylus - suitable substance on either surface prevents accumulations on stylus
Inventor: SCHULTZ BODO
IPC: G11B3/58
Filed: 1973-08-29
Abstract: The invention provides processes and an arrangement to improve the quality of reproduction of recordings, particularly video discs by improving the contact between stylus and disc. This is attained by using a substance, which is applied to the stylus or disc so as to prevent the accumulation of substances on the stylus which inhibit contact. The arrangement comprises a compact unit which is arranged alongside the turntable and contains a polisher for the scanner stylus and a liquid container. After polishing, a playing procedure can be started whereby the stylus is moved by its carriage to the recording medium and brushes against a wick extending upwards from the container which holds silicon oil.

Title: Passenger vehicle safety belt installation - has selector bolts on adjustment knob at retention end and extendable components at other end
Inventor: GERTH WALTER
IPC: B60R22/28
Filed: 1973-09-03
Abstract: Energy absorbing device, used in passenger vehicle safety belts, gives variable absorption of energy dependent upon its volume. The device comprises several deformable components which are on the one hand orientated towards the belt whilst the other end is controllable by means of selector bolts on the adjustment knob on the closure tongue. When a tractive force arises between the two points mentioned above, according to the adjustment of the knob, more or less of the deformable components are capable of extension so as to cancel out the energy application, whilst the other deformable components are not affected due to the selector bolts of the adjustment knob, and do not extend in length.

Title: Gas fired domestic cooking oven - has corrugated sheets between oven sides and outer walls of cooker
Inventor: REUSS WOLFGNAG
IPC: F24C3/00
Filed: 1973-09-15
Abstract: The cooker has an oven with sides placed so as to leave an air gap between the outer surface of the oven sides and the inner surface of the cooker sides. This gap insulates the cooker sides from the heat of the oven. A corrugated sheet of metal is placed within the air gap so as to form a series of adjacent triangular air passages. The passages with their base sides next to the oven walls are closed at the top by a plate while those with their base sides next to the outer walls are left open. Natural convection sets up circulation in these which assists in keeping the cooker.
Patent DE-2349068-A1 (DE)
Title: Microfilm recording unit enabling reading with naked eye - has associated storage for supplying micro-plan film to the recording unit
Inventor: BEHR KARL GUENTER
IPC: G03B21/11
Filed: 1973-09-29
Abstract: The separate micro-plan films are stored next to each other along the surface of a transparent web, which as well as acting as a storage means for the film, also serves to transport the latter past the recording unit. This band may pass around two parallel hubs, so that its upper surface is parallel with the image recording plane. The two hub shafts are rigidly connected by connecting rods and one of them is connected to a hand-operated drive wheel which allows the film to be moved in two coordinate direction parallel to the band surface, to be brought into the correct recording position. The films are pref. secured by a joining clamp which has projections engaging in holes in the edges of the films, the holes and projections being positioned so that the films can only be mounted the right way round.

Title: Cheese fragments transfer distributor - on whey extraction conveyor through inclined, vertical and overflow labyrinth plates
Inventor: LENZ CONRAD
IPC: A01J25/08
Filed: 1973-11-02
Abstract: Cheese fragments from a container are transferred to the conveyor for the charging hopper of a portion separating machine through a labyrinth type of back-end arrangement. The labyrinth consists of a first divergent and rising plate, followed by a vertical plate extending downwards, leaving a gap near the bottom, and a third plate shaped like a rounded overflow weir. This results in a more uniform distribution of the cheese fragments over the conveyor where the whey is removed, and in a more uniform prod.
Patent DE-2355799-A1 (DE)
Title: Shouldered plug for holding tubes on shuttering - is nailed on planks by using tube as nailing tool
IPC: E04G15/04
Filed: 1973-11-08
Abstract: The shouldered plug is used for supporting short tube lengths in concrete during concrete placing. These tubes are used especially as threaded sockets in concrete. The length of tubing is held on the central part of the plug and the tube base is in contact with the shoulder of the plug. The tube base is in line with the nails in the shoulder, and the tube can be used as a hammering device for nailing the plug into the plank. The tube is held firmly on the shuttering and concrete cannot enter the part of the tube filled with the plug. Alternatively the non-threaded part of the tube can be flattened and bent for keying and preventing entry of concrete.

Title: Cut-tobacco meter device - has outlet opening of shaft controlled in cross section by flap with layer height sensor actuation
Inventor: WAHLE GUENTER
IPC: A24C5/39
Filed: 1973-12-17
Abstract: Meterer for cut tobacco to form a tobacco fleece or strand for prodn. of cigarettes or cigars has a damming shaft forming a defined tobacco supply and controllable removers for the tobacco from the shaft. The shaft has an outlet opening which is variable in dependence on the layer height of the removed amt. of tobacco.
