Patent DE-2726131-A1 (DE)
Title: Automatic document set forming mechanism - varies magazine positions to adjust overlap along conveyor and assemble document sheets
Inventor: HOPPE JOACHIM
IPC: B65H39/04
Filed: 1977-06-10
Abstract: The mechanism forms sets from drawings, documents etc. of the same or different sizes, there being a magazine for each document type with a mechanism delivering one at a time, while the magazines are positioned one after the other along a conveyor. The individual documents are delivered from the underside of their respective stacks, and assembled by the conveyor one above the other. The necessary offset to cause the documents to overlap in each set is adjusted by varying the positions of the magazines (7) along the conveyor. This adjustment can be made in the lengthwise direction of the documents, and by varying the intervals between the magazines.

Title: Hobbing machine for straight or helical gear teeth - has electronic logic circuit to synchronise angular positions of tool and gear blank
Inventor: SFAX EGON DR ING
IPC: G05B19/18
Filed: 1977-07-27
Abstract: Electronic logic circuit for operating a gear hobbing machine, where separate servomotors drive the hobbing tool and the workpiece carrier, one leading,the other following. The motor emits signal pulses defining its angular position and fed to a memory store, which emits a standard number of pulses for a servo motor which includes the desired transmission ratio. Pulses are fed to an adder together with additional pulses when helical teeth are to be cut, and the adder provides data stored in a register. The register is connected to a calculation circuit feeding appts. which includes logic gates; a counter; and an analogue/digital converter feeding a pulse generator. The pulse generator receives a signal from the first motor and is connected via a gate to a pulse discriminator feeding an amplifier directly connected to the servomotor.

Title: Subscriber telephone switching system - has analog and digital options for local exchange working using two-wire analog for four-wire digital connection
Inventor: STREHL HERBERT DIPL ING
IPC: H04M1/253

For digital working, the instrument has a four wire connection (19') to the exchange (9) so that incoming signals are connected to an A/D or D/A converter (44), into the hybrid (45), along the bus (43), hybrid (42), and digital originated signals into the digital section (21) of the instrument. Another alternative has no bus (43) but direct analogue or digital connection with switched changeover.
Patent DE-2847626-A1 (DE)
Title: Vibration technique for measuring liquid and gas density - using magnetic vibration connected to amplifier and time base to determine density of fluid in vibrating element (OE 15.10.79)
Inventor: KRATKY OTTO PROF DIPL ING DR D
IPC: G01N9/00
Filed: 1978-11-02
Abstract: The density of liquids and gases is determined from the vibrational characteristics of an element containing a sample. The vibration is amplified and passed to a modulo-P-divider. From the bore the signal is split and one goes to a ramp generator. A second signal goes to a time base which provide a control input signal to a totaliser. The output from the ramp is passed to the totaliser as is the original signal from the divider. The totaliser will then integrate the output from the ramp generator over a set time with the sample in the vibrational element and with the element evacuated. The time is equiv. to the oscillation time of the vibration or a multiple of it. Used for measuring the density of liquids and gases and provides a simple, battery operated device of low cost yet effective in use.

Title: Nut on screw spindle in model vehicle control - is moved in opposite direction when motor direction reversed, and under pressure from discs on spindle
Inventor: MELCHER HANS
IPC: A63H27/08
Filed: 1978-12-04
Abstract: The control is for the movement pattern on model aeroplanes, boats, and similar, driven by an appropriate motor. On a shaft (3) connectable or connected to the motor shaft (1) is fitted a screw spindle (4) centrally. On the spindle (4) is a threaded nut (5) movable lengthways in either direction. At both ends of the shaft (3) coil springs (8, 9) are fitted and which press discs (12, 13) from both sides against the screw spindle (4). When the nut is moved in either direction or is retained in the free run position, and the direction of rotation of the motor is reversed, the nut (5) is then moved in the opposite direction.

The sections of the flat sliding clasp fastener can run almost the whole length of the slit, and form a right-angled triangle so that one line runs parallel to the edge, one line is parallel to the leg seam, and the hypotenuse runs to the outer side of the slit. There are hooks to hold the flap in place at the overlap of the section.

Title: Refuse conversion into compost - by dumping in open air layers on air filter beds
Inventor: WILLISCH HANNES
IPC: B09B3/00
Filed: 1979-03-10
Abstract: Refuse and refuse-sludge mixts. are processed into compost in open-air dumps (in European latitudes) using air filter beds on pallets. A first gravel layer is followed by a sand layer and a fine layer of peat. The first layer of refuse or refuse-sludge mixt. is laid on this bed to a height of 1.2-1.5m. Wire mesh pipes are arranged in a regular pattern to create vertical air shafts. After three weeks the first layer has become matted and stable enough to receive a second layer of 1.2-1.5 m thickness. The pipes are drawn out enough to leave behind uncased air shafts. This can be repeated several times and is a reliable way of low-cost composting and is not affected by the European weather conditions.
