This valve system may be fitted with a spacer piece (2), and a pressure plate (3) with elastic sealing (4). The needle is pref. 1 to 2 mm. in dia. This provides smooth and effective injection of sealant or filler, without risk of damage.
Patent DE-2919745-A1 (DE)
Title: Flexible inlet hose for washing appliances - having magnetic valve at tap end operated by cables within hose wall
Inventor: BRAUN ALFRED
IPC: D06F39/08
Filed: 1979-05-16
Abstract: In household washing appliances, such as washing machines or dishwashers which are connected to a kitchen tap by means of a flexible hose, the inlet valve of the machine is situated at the end of the hose remote from the machine, and is affixed directly to the tap. The magnetic valve is operated from a low-voltage transformer within the machine, via conductors which are advantageously incorporated within the walls of the hose, and remains closed when there is no current. The hose is thus relieved of the pressure of the water main, except when admitting water to the machine, and rupture of the hose effects immediate closure of the valve preventing water damage in the event of accident.

The unit can be a bolt, engaging a slot across the bar, in the sliding piece, eccentrically sited inside a cylindrical shaft (8) on this. Imitation bars are easily fitted, using adhesive, and readily removable for cleaning.
Patent DE-2928062-A1 (DE)
Inventor: GUT LEO
IPC: B29C39/20
Filed: 1979-07-11
Abstract: The process according to the invention serves for producing a weatherproof board, for example for garden tables, table-tennis tables or tables for other games. This board has an upper layer (8) of a synthetic resin and a lower layer (9) of a synthetic-resin mortar. In addition, it has an edging (6) of PVC strips, marking surfaces (7), embedded into the synthetic-resin layer (8), and fastening elements (11), cast into the synthetic-resin mortar layer. The synthetic-resin layer (8) is first of all dried, after which the synthetic-resin mortar layer (9) is introduced and subjected to high-frequency vibration and the PVC strips, which are chemically partly dissolved thereby, are pressed by pressing elements perpendicularly with respect to the board, so that a shrinkage of the synthetic-resin mortar layer in the direction of the board is not prevented on account of a slight displaceability of the PVC strips. <IMAGE>

Title: Environmental pollution prevention during coke oven filling - by mixing exhaust gases into filling gases and washing out
Inventor: POLENZ JOACHIM DIPL ING
IPC: C10B27/00
Filed: 1979-12-06
Abstract: Gases escaping during the charging of horizontal coke oven batteries are rendered inert by mixing them with exhaust gases. They are then sprayed with water as they are fed through a filling gas duct and are finally blended into the raw coke oven gas in the duct behind the precooler. The washing water, containing tar and coal, from the filling gas line is delivered to a thick tar separator, and after separation is complete it is returned to storage.. Problems of environmental pollution, which are made more acute by the use of preheated coal, are successfully overcome.

Title: Heat insulating wall rendering application - involves U=profile rail on wooden or plastics batten, holding panel edge
Inventor: GEISER EDUARD
IPC: E04F13/04
Filed: 1980-02-11

Title: Non-foamed polyurethane bonding for tufted textiles etc. - gives improved adhesion and wearing properties
IPC: D06N3/14
Filed: 1980-04-05
Abstract: Tufted material, partic. for use as hardwearing floor- covering, is bonded on the underside with a thin film of non- foamed polyurethane, forming on the underside an encapsulated 'pile' from the projected undersurface of the pile loops. The material is thermoplastic, whereby fitted, three-dimensional shapes may be formed suitable for vehicle interiors, etc. The polyurethane is sprayed onto the tufted base material along with a foaming inhibitor, or is mixed with minimum water to form a high-viscosity soln. which hardens rapidly before foaming or before it penetrates to the face of the backing material. This construction is much harder-wearing than a foam-backed material. It can be mfd. more quickly, using less material, and in a single coating operation, giving considerable mfg. economies. The coating has imp-adhesion to both pile and backing, and is heat and moisture-resistant.

Title: Efficient energy recovery via turbines - from waste gas obtd. during continuous direct redn. of iron ore
IPC: C21B13/02
Filed: 1980-05-14
Abstract: The ore is reduced by a redn. gas heated in a reformer and fed through a shaft furnace contg. the ore. At least part of the throat gas leaving the shaft furnace is recycled to the reformer with a hydrocarbon, e.g. natural gas, to make more redn. gas; and the reformer is heated with throat gas and/or natural gas. At least part of the flue- or waste-gas leaving the reformer is used to heat a medium (I) employed in a thermodynamic process for creating energy. Medium (I) is pref. compressed air used to drive a turbine; or water, which is converted into steam to drive several turbines employed to rotate fans or compressors used in the redn. plant.

Title: Restraining gp. of esp. vertical steam pipes - by cylindrical frame with horizontal perforated plates
Inventor: NICKEL WALTER
IPC: F22B37/22
Filed: 1980-07-19
Abstract: A deflection preventer for a large number of pipes and tubes, which pass through a top cover of a casing seated in a vertical chamber of a pressure vessel, consists of a restraining framework composed of a number of cylindrical plate rings, one above another, and an equivalent number of horizontal plates each with apertures for the pipes to pass through; support elements resting on the flange of the lid support the restraining framework, while each horizontal plate (16) rests at its outer periphery on one of the cylindrical rings. In particular for restraining and guiding the large number of tubes leaving the top cover of a heat exchanger (steam generator) housed in a pressure vessel of a nuclear reactor system. Such tubes can be comparatively long and thin with very small spaces between them and must be correctly positioned. The structure provided achieves this. In the case of a pipe fracture it prevents the damage from spreading. The structure is also able to withstand the high temperature loading resulting from an escaping jet of steam.

Title: Hydraulically operated drum brake - has shoes mounted on backplate so as to avoid generation of radial torque
Inventor: GUTHMANN HERBERT ING GRAD
IPC: F16D65/22
Filed: 1980-10-24
Abstract: The hydraulically-operated drum brake has shoes mounted on a backplate and moved radially outwards against the drum by a cylinder. The shoes (5,6) are so mounted on the backplate (1) that no torque is exerted on them in the radial direction. The shoe can be held against their supporting bracket (7) by a retaining spring (9) exerting no torque on them, this and the inward force exerted by the drum being sufficient to hold them off. The design avoids the need for a return spring, while keeping the brake at constant adjustment automatically as wear takes place.
