Patent DE-1806190-A1 (DE)
Title: Moulding machine size control
Inventor: CLAN FINK ROBERT
IPC: B30B15/18
Filed: 1968-10-31
Abstract: The faces of the parts which move towards each other (press plungers or rollers) are fitted with nozzles so that a relative motion of the two parts changes the flow resistance of the medium passing through the nozzles. A control unit converts the pressure variations at the nozzles caused by the flow resistance variations into changes of the relative position of the two parts. The preferred medium for the gauge nozzles is compressed air. To prevent clogging the nozzles are surrounded by a groove with a slot leading to the outside while the nozzle itself stands back from the opposite face.

Title: Sepn of nitric acid from organic nitrated derivs - by distn of nitric acid using hot conc sulphuric acid
Inventor: BRUENEMANN HILMAR DIPL-ING
IPC: C01B21/46
Filed: 1973-07-28
Abstract: Nitric acid is sepd. from nitrated organic derivs. by introducing the mixt. into a bath of sulphuric acid heated to a temp. >=5 degrees C above the b.p. of the mixt. thus provoking distn. of the nitric acid. The nitrated organic derivs. can then be recovered from the sulphuric acid. This method is used in the prepn. of nitrated organic derivs. to allow the safe use of nitric acid for direct nitration, without recourse to large quantities of acid which are subsequently wasted, and without the risk of explosion due to the presence of critical quantities of nitrated deriv. in the nitric acid.

Title: Pressure release valve for pressure cooker lids - is operated by lever determining extent to which it is opened
Inventor: RECK ANTON
IPC: A47J27/09
Filed: 1973-08-31
Abstract: The pressure release valve in the pressure cooker lid is operated by a lever which is shaped like a cam near its axis of rotation which is at right angles to the valve axis so that by pivoting the lever the valve can be forced out of the housing member on the lid to the required extent so that the steam can be allowed to escape as slowly or as quickly as desired. The lever can be mounted on the valve member and supported with its cam-like recess on the housing element or it can be mounted on the housing element or a separate holder resting thereon and supported by its recess on a projection of the valve member. The valve can be held in the respective position by the lever so that the operator can continue with other work.
Patent DE-2348945-A1 (DE)
Title: Lateral force compensation in induction wattmeter discs - is achieved by magnet which compensates front-back and left-right forces
Inventor: SCHREINER HEINZ
IPC: G01R11/17
Filed: 1973-09-28
Abstract: The wattmeter consists of a disc in which currents are induced by a voltage electromagnet and a current electromagnet. These rotate the disc but also produce lateral forces which tilt the disc in a left-right and a back-front direction. The system described here consists of a small magnet placed so that both these forces are compensated for at once. Advantage is taken of the various forces to place the magnet so that it is as small as possible. Rotation of the disc still takes place but the cancellation of the unwanted forces reduces the load on the bearings, reducing friction and wear.
Patent DE-2358894-A1 (DE)
Title: External ignition motor vehicle engine - has more than one firing stroke in a complete cycle of piston movements
Inventor: BEHRENS LOTHAR
IPC: F02B75/02
Filed: 1973-11-27
Abstract: The engine has a conventional arrangement of cylinder, piston, connecting rod, sparking plug inlet valve and exhaust valve. On the first half revolution the inlet valve opens and admits air fuel mixture. On the second half revolution compression takes place with firing and working stroke following on the third half revolution. On the fourth half revolution both valves remain closed and the partly burnt mixture is recompressed. On the fifth half revolution a second firing and working stroke takes place and the exhaust valve opens on the sixth half revolution which completes the cycle. This achieves more complete combustion and reduces atmospheric pollution. The cycle is also applicable to compression ignition engines.
