Title: Waste water pumping plant control system - has diaphragm actuated switch for automatic switching of pump motor
Inventor: FASS WERNER DIPL ING
IPC: E03F5/22
Filed: 1973-12-10
Abstract: The waste water pumping system has a maximum of two electrically powered pumps. The actuating switches of these pumps are connected to diaphragms held at high water level in the waste water tank wall.

Title: Compressed gas generator esp for motive power - comprises cylinder with explosive constituent inlets and igniter
Inventor: TUCHENHAGEN OTTO
IPC: C06D5/00
Filed: 1973-09-19
Abstract: A device for producing compressed gas comprises a pressure chamber equipped with an igniter, which is actuated by a contact manometer or pressure switch to ignite explosive material introduced at either of two opposed inlets. Pref. the separate constituents of the explosive are introduced at both inlets, so that they are mixed only when they arrive in the chamber. Used for applications where compressed air would be useful, except for its expense, e.g. for sewage pumps. The device enables compressed gas to be produced when required at low cost. If the constituents of the explosive are not mixed until they enter the chamber, the degree of safety is high.

Title: Continuous prodn of bakery snack items - by extrusion of batter into micro-wave oven
Inventor: ROTH HOWARD
IPC: A21C11/16
Filed: 1974-01-08

The chamber passes vertically through a microwave cavity and the batter is forced through the chamber where it is cooked to give a solid rod of cake which is subsequently sliced into individual items. Other extrusion nozzles may be used to inject a filling into the rod of cake as it passes through the baking chamber. Pref. the inside walls of the baking chamber are coated with a non-stick material.

Title: Cct breaker with closed quenching chamber system - has insulating partition dividing chamber into two nozzle connected compartments
Inventor: SCHMITZ WOLFGANG DIPL ING
IPC: H01H33/90
Filed: 1974-02-01
Abstract: The quenching chamber is filled with pressurised sulphur hexafluoride, and the light arc during switching off is drawn between the stationary and moving contacts. One of the chamber compartments houses the quenching contacts and is connected to the other adjacent compartments by a nozzle shaped aperture, a moving contact extending in its ON condition through this aperture, while during switching off the moving contact(s) is retractable through this aperture drawing the light arc behind. The increased pressure and temperature in the first compartment provides the quenching gas stream from the first compartment into the other on ones, as in 2,339,652. A piston cylinder unit, actuatable by the switch drive, assists during the switching off the gas flow from the first compartment into the other ones.

Title: Position of movable object detecting device - esp. suitable for disc connected to driving shaft of IC engine
Inventor: BREMER WOLFGANG DIPL ING
IPC: H03K17/97
Filed: 1974-08-29
Abstract: An impulse generator is simple in construction yet provides an exact positioning, and consequently also time pinpointing, signal. The disc carries at least two marks, and forms, together with a fixed sender, a pulse generator, followed by a pulse shaper. Two marks (21, 22) limit a certain zone on the movable disc. Each mark (21 or 22) of a pair generates in the sender a different pulse for further processing, and the pulse shaper has at least one threshold stage. The arrangement can also be used for position recognition in machines working with several cylinders. It is especially straightforward and cheap when the marking elements are made from permanent magnetic metal.
Patent DE-2451477-A1 (DE)
Title: Inductive circuit which includes switching transistor - also includes capacitor in freewheel circuit which is used for absorbing magnetic energy
Inventor: FREIER DIETER
IPC: H02H9/00
Filed: 1974-10-30
Abstract: In switched inductive circuits it is necessary to provide for the discharge of the magnetic energy. Some of this energy can be recovered if the switching transistor (S1) is provided with a freewheel circuit containing a capacitor (C1), and blocking diode (D1). When the transistor (S1) turns off the magnetic energy stored in the inductance (L1) is transferred to, and stored by, the capacitor, the auxiliary transistor (S2) bridging the inductance being in the off condition. At the start of the next switching cycle both transistors turn on the capacitor discharges into the inductance. The voltage appearing across the transistors can thus be set at a desired value by suitable selection of capacitance.

Title: Electronic and optical distance meter - uses infra-red radiation to determine the relative distance between two objects
Inventor: SACK FRIEDRICH
IPC: G01S17/931
Filed: 1974-11-25
Abstract: The device for measuring the relative distance between two objects, typically moving vehicles uses infra-red radiation. One vehicle has two transmitters (1, 2) for infra-red beams (B, C) which are 180 deg. out of phase. The reflected beam from the next vehicle returns to a receiver (3) between the two transmitters. The outgoing signals are at 1 khz. The returned signals are fed to a comparator actuated by a photodiode, on each side, so that the comparators give an output signal to a differential amplifier which is proportional to the relative displacement of the two vehicles.

Title: Lower cutter for multiple circular paper cutters - has flat web and circular rim with stabilising rubber filling of corners
Inventor: HAEGER JOHANNES
IPC: B26D1/00
Filed: 1974-12-24
Abstract: The lower cutter for multiple rotating shear has a flat circular web and raised and chamfered circumferential cutting edge. This lower cutter is used in a continuous paper strip cutting machine working at high speed. The cutter flat hub (1) carries on its circumference a cutter with cylindrical outside surface (2) and with inwards sloping relieving chamfer (3) for forming cutting edge. The corners between the cylindrical rim and the flat web of the hub is filled with adhesive bonded or vulcanised welded rubber insert (5) whose outside surface (6) forms continuation of the relieving chamfer (3) and slopes towards the hub centre. This insert which acts as a damping body and reduces the high pitched noise generated during cutting, also deflects paper dust and prevents it caking so that this cutter is able to rotate at all times without unbalancing effects due to the paper dust accumulation.
