Title: Metal-mesh-reinforced plastics foil - the wire of the mesh being coated with a dissimilar metal having lower melting temp
Inventor: HARIG FRIEDRICH
IPC: B32B15/08
Filed: 1973-10-16
Abstract: A metal-reinforced plastics foil e.g. a fluoro polymer sintered onto the metal mesh has the points of intersection of the wires forming the mesh, welded together by thermal post-treatment of the foil. In the patent of addtn., the wires used for the mesh have a coating a metal whose m.pt. is lower than that of the cores. This means that a considerably lower temp. is now sufficient to bring about the welding together of the insecting wires during thermal post-treatment since only the metal coatings need be fused. The metal coating of the wires may be of Sn.

Title: Non-return valve with spring-urged disc - has spring abutment in housing formed by two half-rings
Inventor: STICHERT KLAUS-E DIPL ING
IPC: F16K15/06
Filed: 1973-12-06
Abstract: The spring is a compression spring situated axially between the disc and an abutment plate, both of which are situated between the radially inner edges of axial ribs at the interior of the valve housing. The disc abuts the valve seat and the plate is held in position axially by radially inner portions of the two half-rings, radially outer portions of the rings being seated in grooves in the ribs. Spaces between the adjacent ends of the two half-rings are engaged by radial projections of the plate. Compared to the circlips used in the parent case, the half-rings are more easily assembled and are independent of the need to use spring material.

Patent DE-2406313-A1 (DE)
Title: Pressure reducing valve for welding torch connector - has two spherical balls acting as throttle valves
Inventor: MAYS HAL N
IPC: F16K1/30
Filed: 1974-02-09
Abstract: A pressure reducing valve is screwed e.g. into a gas bottle for welding equipment. With the valve closed, the gas flow is obstructed by two unequal size steel balls which are held against the steps of a hole under spring load. A spring loaded adjustable piston enters the hole down stream of the second ball. The following ring chamber communicates with an outlet needle valve and also with the cylinder which carries a piston and regulating spring. When the regulating spring is compressed, its piston extension lifts the two balls of their valve seats. As the gas flows from the pressure vessel, it is throttled by the two balls. With the outlet needle valve open, the regulator spring can be adjusted to give outlet flow at constant pressure.

Title: Roller-mounted pile raising machine for heavily soiled carpets - thoroughly loosens dirt and pile prior to standard shampooing
Inventor: SCHROEDER HERBERT
IPC: A47L11/32
Filed: 1974-06-21
Abstract: The pile raising machine comprises one or more rows of stiff, (steel) wire brushes (2, 3) in which the individual bristles (12) are resiliently mounted to run across the direction of movement. The machine is moved over the dry carpet against the pile so that the bristles penetrate down to the backing material thereby completely loosening up the pile to expose the dirt particles which are then removed by suction before the normal shampooing process is carried out. The suction means can be incorporated together with the normal electric motor in this machine. The top of the machine housing or brush support (1) is adapted to receive weights (9) so that the penetrating depth of the bristles can be altered by adjusting the weights on top. Castors (7) can be provided at the end of the housing remote from the brushes to facilitate movement over the carpet.

Title: Coupling for round threaded parts or tubes - coupling thread and one part thread have different pitch to other thread to provide clamping force
Inventor: HOOGEVEEN FRANK
IPC: F16L15/00
Filed: 1974-11-16

Title: Integrated monolithic circuit - with step between thicker epitaxial layer in analog section over base regions of equal thickness
Inventor: HERRMANN HANS DIPL ING
IPC: H01L27/02
Filed: 1974-11-22
Abstract: A monolithic integrated circuit with an I2L section and a bipolar analog section has planar base regions in the exposed surface of an epitaxial n-type layer which forms a junction with the monocrystalline p-type substrate; a highly dope n-type intermediate layer is left under the base region of the I2L section. The base regions of both sections have the same thickness but the epitaxial layer of the analog section is thicker so that a step is created between the two sections at the exposed semiconductor surface. This results in a high current amplification in the I2L section, without reducing the diaelectric strength of the analog section. The mfr. requires no great extra effort, specially regarding the number of planar diffusion processes.

Title: Fastening plate for shaped glass - has flanged glass ends drawn in by plates at joint
Inventor: SCHOENER ANTON
IPC: E06B3/54
Filed: 1975-02-01
Abstract: The fastening plate has a covering cap, and is for single-skin profiled glass in U-frame mountings. The fastening of the glass (3) and the covering of the frame (1) is effected by two separate sections.

Title: Self securing railway goods wagon - has coupling pin retaining hook with projecting stop for service lever recoupling
IPC: B62D53/12
Filed: 1975-03-11
Abstract: The coupling consists of a base (1) with a wedge shaped slot (2) to receive the coupling pin (3) which is secured by a retaining pivot hook (5).

Title: Sewage aeration device - with gas distributor having porous walls rotating relative to fluid deflectors for finer bubble generation
Inventor: STOCKNER JOSEF
IPC: B01F3/04
Filed: 1975-04-01
Abstract: A fluid serration device for use in the treatment of effluents is fitted with a disc-shaped or cylindrical gas distributor for oxygen or air which can be rotated relative to a fluid deflection system. The deflecting elements (deflector vanes or nozzles) of the deflection system face a certain part of the gas distributor surface which is preferably porous and exert a shearing force on the emerging gas flow. This produces extremely fine bubbles with no extra energy expenditure. The bubbles are uniformly distributed. Gas distribution is combined with an effective fluid circulation.
