Title: Interlocking cct. for several switches - uses current limiter in form of monostable key switches in series between cct. input and feed lines
Inventor: HABERL MANFRED
IPC: H02H11/00
Filed: 1973-08-24
Abstract: The interlocking circuit is intended to prevent simultaneous switching-on for two or several switches, whose control inputs are in parallel between two feed lines over series connected monostable key switches. The current is supplied by a constant source. The switches are of electronic type or of electronically controlled electromagnetic type, whose control inputs are each bridged by an ohmic resistor. The switching points of the electronic switches and the embossed current for the feed lines are so chosen that the entire current flowing through a resistor causes there a voltage drop in excess of the switching voltage of the respective electronic switch. The half current value generates a voltage drop below the holding voltage of the electronic switch. On switching-on the electronic switch actuates a contact bridging the respective monostable key switch.

Title: Potato sugar leaching - by rapid freezing
Inventor: HOWARD HENRY H
IPC: A23L19/18
Filed: 1973-11-14
Abstract: Sliced potatoes contain sugar which becomes caramelised when the potatoes are fried; this surface sugar may be removed by first freezing the potatoes in a refrigerant bath for a short period of typically 5 sec. and then immediately warming the slices to drive off excess refrigerant. This process ruptures the surface cells whose sugar is then leached out in a bath of warm water. The freezing is carried out in an insulated chamber with an internal dividing wall sepg the freezing bath and the refrigerant recovery heaters.

Title: Biological treatment plant for sewage - with automatically cleaned bar screen between sand trap and rain water clarification
Inventor: DANJES MARTIN DIPL ING
IPC: C02F3/12
Filed: 1973-10-01
Abstract: A biological sewage treatment pland consists of an annular aeration tank, surrounded by a coaxial final clarification tank to which it is linked by a slot at the bottom. A revolving arm which sweeps over the tank and carries paddles at the bottom is fixed near the centre with a scraper for an annular bar screen at the top of a sand trap; the star-shaped scraper is turned once every revolution by a stop to clear it. This improves the preliminary cleaning of crude sewage entering the sand trap. The deposition of sludge in the rainwater clarification basin is prevented when used as a settling basin for sewage overflowing from the sand trap.
Patent DE-2400505-A1 (DE)
Title: Seal between annular body and cylinder - has second annular body movable axially to press seal against cylinder
Inventor: PFEIL ANTON
IPC: F16J15/3268
Filed: 1974-01-05
Abstract: The seal assembly includes an O-ring whose inner diameter is greater than the outer diameter of the cylinder. The annular bodies which initially are spaced apart axially, engage the O-ring between them. One of the bodies has a conical face adjacent the O-ring so that when the bodies are pressed together axially the O-ring is deformed radially inwardly and makes sealing contact with the cylinder. By this arrangement the insertion of a cylinder having a sharp end edge into position in the bodies does not damage the O-ring. The conical face faces radially inwardly and in the direction in which the cylinder is to be inserted.

Title: Electrical slide connector - pivot at end of internal lever arm moves pin and bush towards each other
Inventor: ROESCH GUENTHER ING
IPC: H01R13/629
Filed: 1974-07-25
Abstract: The arrangement for connecting two conductors uses two coupling members: one containing a socket bush, and the other a contact pin, which by means of an actuating device are slidable against each other and where at least one of the coupling members is guided in a carrier. In the coupling carrier one end of a crank arm is rotatably embedded while the other end extends into the slidable coupling member. Turning of the embedded end of the crank arm produces a shift of one coupling member against the other. Either or both coupling members may be fixed in location. The crank arm may take the form of an angle lever the apex of which rests in the carrier housing and from whose end pivots project which interact with one of the coupling members.

Title: Electrooptic and inductive coupler - has constant frequency chopper for DC between input electro-optical coupler and output transformer
Inventor: LONGCHAMP JEAN-FRANCOIS DIPL P
IPC: H03F3/38
Filed: 1974-08-30
Abstract: The electro-optical and inductive coupler, for connecting an input to an output stage, has the input stage coupled via an electro-optical coupler (13) to the input of a pre-amplifier (14). The pre-amplifier has an output which is chopped (15, 16) at a constant frequency and the chopped output is applied to an operational amplifier (17). The operational amplifier has an output which drives the primary winding (18) of the transformer (19) that forms the inductive coupling to the output stage (20). The output stage has an LP filter (24) which is used to suppress the chopper frequency. The advantage lies in the coupler having a power transfer ratio greater than unity and in being able to handle d.c.

Title: Microfilm camera for roll film and slides - accessory condenser lens converts to projector for both
Inventor: SCHAUT JOSEF
IPC: G03B27/46
Filed: 1975-08-30
Abstract: The film cassette used is of the same size as the slide cassette, but has a side-chamber to carry the film into position for exposure. The side-chamber occupies the space that is otherwise occupied by the slide-locating plate. The film spools are turned by a roller inside the cassette, which contacts the rollers outside the cassette that drive the slide feed in the camera's other operative mode. When a cover is replaced by a condenser lens, the device acts as a projector. The film is then taken out of the cassette through a slot, instead of doubling back towards the take-up roller.
