Title: Induction air preheating system - has branch pipe with flap valve to select silencer cooling or intake air heating
Inventor: BENDER KARL-H
IPC: F02M31/093
Filed: 1976-07-30
Abstract: A casing (6) surrounds the exhaust pipe section (4) between exhaust manifold (3) and silencer (5) to form a gap (7). The manifold end of the casing is provided with a union (9) to carry a tube (9).

Title: Moving machine part hydrostatic support - has resilient connector between floating support block and machine to compensate for load variations
Inventor: CHRIST ALFRED DR
IPC: F16C32/06
Filed: 1976-08-03
Abstract: The hydrostatic support for a moving machine part (1) has a bearing block (3) supporting the underside (2) of the part, and fitting into a channel (6) in the frame (7) of the machine.

Title: Talcum powder sprinkler cap mounted on tennis racket handle - has two rotatable concentric hemispherical sprinkler shells enclosing powder
Inventor: TERMIN WALTER
IPC: A63B49/08
Filed: 1976-10-05
Abstract: An hemispherical sprinkler cap (6) which can be filled with talcum powder, is attached to the rear end face of a tennis racket handle (1). A central stud (3) in the handle face (2) locates and clamps the flat base (5) of the sprinkler cap. The sprinkler has two concentric shells (4, 6) which can be rotated relative to each other. Since both shells have radial holes, (8, 9) which can be made to be in line when the cap is open, they can also be out of line in order to close the cap. Thus during normal play, no talcum powder is lost from the sprinkler cap.

Title: Cowl structure for paper-making drying cylinder battery - is extremely compact and forms itself channels for distributing air
Inventor: PRICE DONALD
IPC: D21F5/02
Filed: 1978-04-11
Abstract: Drying cylinders for papermaking and similar machines are housed in a partly enclosed structure in which there are, (a) sections or modules; (b) a support structure formed by tubes of square or rectangular cross-section running lengthways, transversely and vertically, along which the hot air circulates towards outlet pipes, provided between the cylinders of each section; (c) an inlet fan and an outlet fan for each section; (d) an inclined partition dividing the cowl into a heating zone and a cylinder zone; (e) a heat recovery unit and a steam heating unit in the heating chamber; (f) a conduit for transferring humid air from the cylinder zone to the heating zone; and () a flap valve for controlling the passage of air between the zones; all these pieces of equipment being located inside the actual housing. This cheapens the cost and reduces the space occupied by the battery of drying cylinders and its heat recuperator. The thermal efficiency is much higher since the return passages are inside the cowl instead of outside as normally. The heat exchanger for the fresh air circulating inside the cowl is also an improvement.

Title: Used moulding sand regeneration - utilising ascending air stream protecting sand through expansion space before impinging on disc
Inventor: JACOB HERMANN
IPC: B22C5/10
Filed: 1978-05-30
Abstract: Used moulding sand in foundries is regenerated by a pneumatic system in a rising air stream inside a tube. The sand laden air passes through an expansion space with a length of over 3(5) times the tube diameter before the sand particles impinge on an impact disc which causes the larger particles to drop back into the air stream. This repeated cleaning action removes incrustations so that the laterally escaping sand is fit for re-use.
Patent DE-2827568-A1 (DE)
Title: Air cooling system for cement clinker - where dust free air leaving indirect cooler is fed up direct grate cooler to increase thermal efficiency
IPC: C04B7/47
Filed: 1978-06-23
Abstract: The roasted clinker or similar material leaves a furnace and enters a direct cooler, esp. a grate cooler, from which the clinker enters a crusher and then travels downwards via gravity through an indirect cooler. A row of fans is employed to blow air up the indirect cooler so the air becomes hot while cooling the clinker; and the hot air is then fed to the grate cooler and used to cool clinker travelling along the grate. The fans employed to blow air up the indirect cooler are pref. sufficiently powerful to drive the hot air to the direct cooler without the use of additional fans located between the two coolers. In conventional plant, the air leaving the indirect cooler is dust free and is usually released to atmos., but this wastes the heat picked up by the air while travelling up the indirect cooler. The invention exploits the heat in this air.
