Title: Combined control valve for axle hydraulic dampers - has separate non return valves for each side with centre control preventing uneven deflections
Inventor: SPICHALA PAUL
IPC: B60G17/033
Filed: 1975-07-22
Abstract: The two hydraulic dampers (12, 13) at opposite ends of the same axle are controlled for height using a central control. This controls the combined setting w.r.t. a load sensor (10). It also blocks the line between the elements if one is deflected more than the other, e.g. on slopes. The combined control operates by a simple array of non-return valves. The riding height is increased by two non-return valves (6, 5) between the supply pressure (1) and each element. The return flow is regulated by two further non-return valves (8, 7) set in opposition to each other and which block the line between the elements. A single non-return valve (9) operates the return flow from both elements in response to deflections of the riding height monitor (10).

Title: Flue gas washing with halogen cpds. soln. - gives minimal scale formation, liq. being regenerated by alkaline earth carbonate
Inventor: HOELTER HEINZ
IPC: B01D53/60
Filed: 1976-07-17
Abstract: Purifying flue gases, esp. power station gases, consists of gas washing using a liq. comprising an 0.15-5% soln. produced from salts and/or acids of halogens, e.g. ammonium chloride soln. The wash liquid, after use, is neutralised in an alkaline earth carbonate reactor. After leaving the washing plant, the wash liquid is supplied to an oxidn. vessel into which air is blown. It then passes to a carbonate reactor contg. alkaline earth carbonates and a solids collection space. The liquid then passes in modified form (calcium sulphate and ammonium chloride salt) to a settling unit, and so to a vacuum filter where the solid residue is extracted to 10-20% humidity, while the filtrate is recycled into the washing system. Thorough washing is achieved, as is oxidn. of CaSO3 to CaSO4 without difficult control problems and with reduced risk of encrustation of plant components.

Title: Bottle cleaning machine transfer mechanism - has guide fingers on cam guided linkage following looped path to lower bottles
Inventor: SCHOLZ HERBERT
IPC: B08B9/20
Filed: 1977-03-02
Abstract: The bottle handling mechanism for a fast running bottle cleaning machine includes a transfer position where the bottles (23) are lowered from holders (2) after travelling around a conveying wheel onto a nearly horizontal receiving surface (21) and come to rest on a horizontal surface just ahead. The descending bottles are guided by fingers (20) on the ends of L shaped arms mounted on a square cross bar (32).

Title: HV capacitor feedthrough with cooled inner conductor - formed as heat-pipe with longitudinal grooves along inner wall and cooling fins at free end
Inventor: HAMMER FRITZ DR ING
IPC: H01B17/28
Filed: 1977-09-14
Abstract: The high-voltage capacitor feed through has an inner tubular conductor partially filled with an easily vaporised liquid. The principle of the so-called "heat-pipe" as used for the utilisation of solar energy in domestic power plants is applied. So as to reduce as much as possible the overall diameter of the capacitor and the diameter of the inner tubular conductor and, thus, the overall costs, the inner conductor carrying the drive current is formed as a heat pipe with longitudinal grooves in its inner wall. At its free end the conductor carries a series of cooling fins. The grooves are specif. less than 1 mm wide and less than 4 mm deep.

Title: Frame for taking glass elements - is made of moulded section strip, cut to length and welded in corner portions
Inventor: HERZBERG FRIEDEL
IPC: E06B3/62
Filed: 1977-12-19
Abstract: The frame (11) which is to take the glass element (17) comprises four sidepieces (12) each made of one-piece extruded sections welded together at the corners. The pre-fabricated frame can then be shrunk directly or indirectly onto the glass element, e.g. by warming the frame and placing on the glass. Alternatively, the glass element can be cooled to a very low temp. so that it can be inserted in the frame. It is thus only necessary to make a single section of e.g. plastics or light metal, e.g. aluminium which can then be cut to size and the pieces welded together.
