Title: Electrochemical machining or treatment system - with work-pieces attached to fixture with gap maintaining electrodes passing through all stations
Inventor: STAMM HARALD ING GRAD
IPC: C25F7/00
Filed: 1975-02-08
Abstract: In a system for the chemical, electrochemical or electrolytical treatment or machining of workpieces such as aluminium alloy engine blocks, a gap is produced between the workpiece surface and a displacement body or a non-consumable anode.

Title: Non-return valve closed by excessive reverse flow velocity - has piston held open by forward flow and sprung ball in groove
Inventor: WEDLER KLAUS DIPL ING
IPC: B66B5/02
Filed: 1975-02-20
Abstract: The non-return valve has aligned inlet and outlet ducts at the ends of a chamber contg. a closure member (7) supported for movement between an open position medially within the chamber and a closed position engaging a seat (10) at the inlet duct. Forward flow passes all round the member, pushing it into the open position against an abutment (11). A spring-loaded ball (3) engaging a groove in the member holds it with limited force in the open position. If reverse flow exceeds a safe velocity, e.g. as by rupture of a pipe, the detent gives way and the valve closes thereby preventing sudden lowering of a load.

In this way any dirt or food in the trough is rinsed away and the drinking water and trough are kept clean, and suitable for dispensing water to small animals or birds.
Patent DE-2535838-A1 (DE)
Title: Collector, with black anodising surface, for solar cell - with high sunlight absorption, high heat transition coefficient and high durability
IPC: F24J2/48
Filed: 1975-08-12
Abstract: The collector element consists of Al which is black anodised on the surface facing the sun, pref. in matt black, with an anodised layer =20 mu thick. The part of the collector element to be anodised may first be picked in alkali, to obtain a matt surface and prevent any effect on heat absorption by reflection. The result is a combination of high absorption capacity for solar radiation, high heat transition coefft., and sufficient durability even at high temps. Misting up of glass panes placed on top of the collector element by dust particles from the inside cannot occur. The thickness of the anodised layer is sufficient to allow high absorption while minimising losses in heat transition.

Title: Cleaner for loom reed - with cleaning blade travelling full depth of reed and aided by automatically supplied cleaning fluid
Inventor: SCHREUS THEO
IPC: D03J1/00
Filed: 1976-04-09
Abstract: Cleaner for loom reed comprises a cleaning blade which travels the full depth of the reed and which is aided by a cleaning fluid which is supplied automatically by means of a pipe. The blade may be in the form of a dent hook of which the outer cutting edges are obtd. by forming teeth, grooves or any other structure which promotes cleaning. As cementing of the reed gaps can be very tough and the ejected dirt must be conducted away, cleaning is assisted by a fluid e.g., benzene, trichloroethylene, CCl4 etc. which is disposed in a trough immediately underneath the reed. The fluid is entrained by entry of the blade into the reed gap and conveyed by the pipe to the surface of the reed at least in the region of the blade.

Title: Treating PVC based aq. dispersions with gases - continuously in a multi-chamber plant
Inventor: CORNELSEN BRUNO
IPC: C08F6/14
Filed: 1976-04-28
Abstract: Aqs. plastic dispersions in which the polymer portion contains at least 50% polymerised vinyl chloride, are treated with gases in a succession of chambers, the volumes of gas in the chambers being closed w.r.t. each other and being intensively mixed. Transport of gas from chamber to chamber is effected in only one direction and transport of dispersion from chamber to chamber is effected in the opposite direction. The dispersion in the chambers is thus rapidly moved through a suitable means to the surface in the direction of the phase boundary surface between the dispersion and the gas. The dispersion is stopped from flowing back in the direction of the dispersion inlet by mechanical means provided in the lowest quater of at least one chamber, and pref. in all chambers except the first chamber lying the direction of the dispersion flow.

Title: Metal reinforcing sections for edges of skis - has grooves in ski sides to receive flanges of metal channel and increase flexural rigidity
Inventor: STEINHAUSER ALFONS
IPC: A63C5/048
Filed: 1976-11-16
Abstract: A metal C section (3) is used to increase the flexural rigidity of a ski (1). Grooves are formed along the edge of the ski and the section is slid into position. The section is attached to the ski in only on place. This permits relative movement between the ski and section to accommodate differential thermal expansion or contraction due to the wide range of temps. in which skis are used. The section can also be made in a resilient form so that it can be sprung into position. When the increase in flexural rigidity is excessive, slots can be cut in the section in those regions where a lower flexural rigidity is desired.
