Title: Electric warmer for inside of shoe - consists of preheated ceramic core with embedded heating wires and outer insulation
Inventor: STAHL HANS
IPC: A43B7/02
Filed: 1977-12-23
Abstract: The warmer device consists of a pre-heated core (8) of ceramic possessing a high heat-retaining capacity. Next to the inner surface (6) of the shoe is a surrounding layer of (7) heat insulation round the core. The core contains electric heating wires with an adjustable thermostat measuring the temperature of the core. The heating wires are preferably connected to an adjustable time switch.

Title: Embroidery automatic colour change - uses impulses to control piston cylinders to control functional units to execute multi-coloured pattern
Inventor: BOCK LOTHAR DIPL ING
IPC: D05B65/00
Filed: 1978-01-18
Abstract: In an automatic colour change system for an embroidery machine, so that multi-coloured patterns can be executed, pneumatic impulses are generated either by a programming unit or manually, to activate the pistons of >=1 hydraulic or pneumatic cylinder. Through an angled surface they deliver a sideways pushing action to move >=1 functional unit into pre-set positions. The system gives a fully automatic action to change the colours as the embroidery progresses, so that a multicoloured pattern is executed economically and without manual intervention.

Title: Hydraulic flow regulator valve - uses pressure balanced valve operating coaxially in single housing to maintain constant pressure difference of desired valve
Inventor: HOFFMANN RAINER
IPC: G05D7/01
Filed: 1978-02-22
Abstract: A constant flow regulator for hydraulic system applications esp. for small oil flows uses two concentric pistons located in a single housing. One piston (14) has a triangular port (28) that presents a variable restriction to the flow passing from an inlet (18) to the regulator outlet (20). The pressure balanced piston (16) is controlled by a combination of springs (46, 52) located at either end and a feedback pressure signal derived from the output. The pistons operate to maintain a constant pressure difference (P2-P3) even though the inlet pressure-intermediate pressure difference (P1-P2) may vary. An adjusting rod (50) enables the pressure difference (P2-P3) to be selected to achieve the desired value.

Title: Shaft rotational frequency measuring device - has memory mechanism including overrunning clutch, coupled to actuator and return spring with solenoid operated brake
Inventor: BRJUCHOV BORIS FEDOROVITSCH
IPC: G01P3/00
Filed: 1978-03-25
Abstract: The appts. for measuring frequency of rotation of a shaft, connectable to this shaft through a reducing gear having a solenoid clutch at the output, has the output shaft of this solenoid clutch associated with a driver and a return spring. The driver is adapted to rotate a memory mechanism through an actuator fast with the shaft of this mechanism. The shaft of the memory mechanism carries an indicator of the frequency of rotation of the shaft and an overrunning clutch operatively connected with a solenoid brake controlled by a pulse generator. The pulse generator is successively connectable to the solenoid clutch to perform a measurement of the frequency of rotation of the main shaft, and to the outer cage of the overrunning clutch to register the frequency of rotation of the shaft, which is being measured.
Patent DE-2825780-A1 (DE)
Title: Spring karabiner with lift brake - has rope gripped between braking component and clamping piece integral with hook section
Inventor: KUTSCHERA WOLFGANG
IPC: A62B35/04
Filed: 1978-06-13
Abstract: A safety spring hook has a lift brake attached to the hook section. The brake clamps a rope between a braking component and a clamping piece mounted on it. The rope frictionally slides through the lift brake only when a clamping force determined by the clamping piece is exceeded. The position of the clamping piece on the braking component (21) is non-adjustable. The latter (21) is integral with the hook section (17). The spring hook is rapidly fixed to a rope, belt, or chain to prevent workmen engaged on high construction works from falling. Faulty adjustment of the lift brake-in which the rope is gripped either too weakly or too tightly- is avoided. The handling of the lift brake is straightforward so that the use should have no wish to change it from its set optimum position.

Title: Digital semiconductor circuit with series of storage cells - has signal generator which responds to specified state of series of cells and delivers signal which corrects second series of cells
Inventor: MUEHLBAUER OTTO JOSEF
IPC: H03K21/38
Filed: 1978-06-30

IPC: H04Q11/04
Filed: 1979-06-20
Abstract: A method and a circuit arrangement for clock synchronization in the transmission of digital information signals. In the four-wire type transmission of blocks of information signals on a two-wire transmission line it is determined, by phase comparison, whether the first bit in each block of signals (1) falls within a time interval derived from the bit clock signal of the local clock generator; (2) falls within an adjacent time interval or (3) falls within none of such time intervals. Depending upon the results of this comparison, the time relationships are left unchanged, the period of the clock generator is shortened or lengthened one or more times, or a one-time, initial phase equality is established.

Title: Combined ammonia and methanol synthesis - from air and hydrocarbon(s), using high purity hydrogen and nitrogen
Inventor: GOODMAN MICHAEL CHARLES
IPC: C07C31/04
Filed: 1979-10-26
Abstract: Combined prodn. comprises catalytic synthesis of CH3OH from a 2:1 H2:CO mixt. (derived from hydrocarbon starting material). Off gases from this stage are treated to recover pure H2, and separately air is treated to produce pure N2. These pure gases are combined in 3:1 ratio and used for NH3 synthesis. Pref. the pure (>=99.999%) H2 is produced pressure-switching absorption from (part of) the methanol-lean off gases, and is generated at >=35 kg/cm2. Any off-gasses not so treated are recycled. Pure N2 is generated at pressure of H2 and compressed before mixing. The NH3 synthesis zone pref. operates at the pressure at which H2 is produced. NH3 is recovered by condensation with cooling water, deep cooling, or by absorption (pref. in water or dil. aq. NH3 soln.). Inerts do not accumulate in the systems, allowing lower pressure and thus reduced energy demand, typically 7.83 x 106 c.f. 8 x 106 kcals) ton NH3.
