Patent DE-2534663-A1 (DE)
Title: Ball valve with plastic body - is reinforced with metal tube to withstand higher pressures than all plastic valve
IPC: F16K27/06
Filed: 1975-08-02
Abstract: The ball valve has a plastic body moulded around a metal tube. The metal tube has angle section reinforcing rings. A short length of small dia. tube is welded to the main tube and forms the bearing for the valve operating spindle. The spindle has a tongue which engages a slot in the ball. The ball is held in position by the sealing rings. Belleville washers fitted between the coupling nuts and the rings provide a sealing pressure on the surface of the ball. This allows the valve to be used at much higher pressures than is the case with an all plastic valve.

Title: Reinforced concrete wall cornice prefabricated formwork - comprising parallel concrete sidewall beams joined by spacers and tension members
Inventor: GIESLER ROBERT ING
IPC: E04B1/20
Filed: 1975-08-09
Abstract: The prefabricated formwork unit is for the production of cornices in building structures, where there are reinforced concrete wall sections, at ceiling height or just below, providing compensation for the horizontal thrust forces encountered there. It comprises two sidewalls, parallel and interconnected by cross-pieces, for setting on the walls, leaving an intervening open space to be filled with steel reinforcement and cast or dry-mixed tamped concrete. Here the parallel sidewalls (1, 3) are made in the form of prefabricated separate reinforced concrete beams, which can be joined to each other by spacer units (5) and tension members (6). The reinforcements (7) in these beams may protrude from one of their lateral surfaces (10), to form part of the reinforcing units for the cornice. The tension members may be screws and nuts, detachably penetrating the spacers, in the form of sockets, and the beams.

Title: Steam tight joints between plastic coated aluminium strips - where plastic is locally removed for spot welding the aluminium
Inventor: NORMANN KARL-HEINZ ING GRAD
IPC: B23K11/16
Filed: 1975-08-15
Abstract: Steam-tight joints are made between aluminium strips, coated on both sides with plastic, by welding and bonding. The novelty is that at the ends of the strips, small congruent regions are freed from the plastic on both sides and, after placing one strip over the other, the bare regions are spot welded together. The ends of the strips are pref. placed in a slot in a diamond-shaped jig provided with windows, and wire brushes applied through the windows on both sides of the strip t remove the plastic coating in the congruent regions. The welded strip is used as a sheath on data transmission cables. The sheath is applied using an extruder, and the process permits the tail end of one strip to be joined to the leading end of the next strip during the spiral winding of the strip to form a tubular sheath on the cable.

Title: Radiation collector for solar energy - has support tray extended at sides to provide edge insulation round absorber
IPC: F24J2/04
Filed: 1975-10-15
Abstract: The collector is held in a tray with a bottom and sides. There is a layer of insulation in the bottom of the tray and the energy absorber is above this. An air gap above the absorber is closed by a glass sheet cover. The sides of the tray are extended above the absorber and bent in horizontally to form a flange to support the glass cover. The inner edge of this flange is bent down again and then inward horizontally to form a support flange for the absorber. The space left between the two vertical parts of this shape is filled with insulation which forms a thermal barrier round the sides of the absorber and the air gap.

Title: Vehicle DC generator in situ test circuit - has variable reference voltages derived from input voltage to allow for ripple
Inventor: HAUCK WOLFGANG
IPC: G01R31/34
Filed: 1975-11-03
Abstract: The method and device for detecting defective d.c. generators in vehicles is designed for reliable in situ testing without use of expensive or sensitive equipment. The device tests rotating current generators with associated rectifier circuits.

Patent DE-2602360-A1 (DE)
Inventor: WIELAND DIETER
IPC: A61H33/06
Filed: 1976-01-22
Abstract: The device (21 to 36) regulates the air supply to the sauna oven (10) located inside the sauna cabin and in which the air to be heated is supplied from the bottom and emerges into the sauna cabin at the top end after heating. The device (21 to 36) comprises a fresh air supply channel (22) which can be connected to the ambient air outside the sauna cabin and an air supply channel (23) which is open toward the sauna cabin. The cross-sections of the two channels (22 and 23) can each be regulated with an adjustable air flap (24 and 25, respectively). As a result, the heated air which leaves the sauna oven (10) at the top can re-enter the sauna oven (10) at the bottom through the second air supply channel (23) in order to be heated further, so that the energy consumption of the sauna oven is reduced and the costs for heating can be lowered. In this way the sauna cabin can be quickly heated. The adjustable air flaps (24, 25) can be used to adapt the supply of fresh air to the number of individuals present in the sauna cabin. <IMAGE>
