Title: Drive motor unit for curtains - is mounted separately from track for easier control by drive member
Inventor: SEBALD WALTER
IPC: A47H5/02
Filed: 1978-06-06
Abstract: The curtain track has an end piece with a guide roller, and an end piece with a drive roller and chain stretcher. To move the curtains the draw chain runs over the two rollers in the end pieces. The drive unit which can be controlled by a switch, is set apart from the curtain track and is only connected to the drive roller in the end piece by the drive member.

Title: Mechanism for automatic closing of open windows - has closing spring and ratchet mechanism closed by switching clock
Inventor: KLEINLE INGRID
IPC: E05F1/00
Filed: 1978-07-03
Abstract: The automatic window closing mechanism is used to ensure that the window is closed after a specified time for saving heat. A large number of ventilating windows, for example in animal breeding stables, are readily closed without supervision. The window is loaded continuously in the closing direction. The energy used for opening the window is used for closing the window by means of a timing clock and switch. The window actuator has a spring loaded on opening. The mechanism has a ratchet plate connected to the ratchet lever. This lever is released by the timing arrangement for automatic closing by the spring force.

Title: Mine personnel conveyor belt safety device - has pulse emitters at entry and exit points and distance measuring unit
Inventor: DUPONT HARRY ING GRAD
IPC: B66B29/00
Filed: 1978-07-05
Abstract: The safety device is for conveyor belts transporting goods and personnel, particularly in underground mines. The entry and exit points on the belt have pulse emitters giving signals when a person climbs on or off, and a distance measuring unit emits impulses proportional in number to the distance covered. Emitters and measuring unit are connected to a computer and control unit and which incorporates sum storage units equal in number to the persons travelling on the conveyor. Feeding of pulses to these units starts with each person who climbs on, and their content is continuously compared with a constant representing the maximum permissible travel distance, being erased by a pulse from the exit point. When the content exceeds the constant, a stop signal is emitted to the belt.

Title: Fluid small evaporation rate measurement - using displacement body with immersion depth varied to maintain fluid level at reference mark
Inventor: HOFFS WERNER VAN
IPC: G01N25/14
Filed: 1978-09-30
Abstract: The method and device are for measuring small rates of evaporation of fluids are esp. applicable to measurement of thermal consumption of room heating systems.

Patent DE-2851822-A1 (DE)
Title: Fault detector for information storage discs - detects faults due to scratches on spiral track of rotating disc, by using shift registers and logic gates
Inventor: STECHER HELMUT DIPL ING
IPC: G11B20/18
Filed: 1978-11-30
Abstract: The fault detector compares the faulty signal obtained during one complete revolution of the disc with the signal obtained during the preceeding revolution. If the fault repeats itself in the next revolution (or the next two, three etc. revolutions) then a multiple-fault is registered (i.e. a scratch). The disc signal is applied to a first shift register (SR1) whose length is equal to one revolution. The register's inverting output is combined via an AND-gate with the input to produce a fault signal indicating a single fault. A second AND-gate combines input and output to produce a second fault signal indicating several faults.

Title: Transmission level generator-receiver synchronisation - by mixing fundamental frequencies with synchronisation signals and using amplifiers for intermodulation
Inventor: SCHNUERMACHER TAMAS
IPC: G01R27/28
Filed: 1978-12-27
Abstract: The unit is for synchronisation of transmission level generators and receivers, pref. for measurements with carrier frequency devices, and provides a synchronising signal to the synchronisation input of the device and receives a synchronisation output signal from it. It enables measurement of modulation or intermodulation errors of amplifiers, mixers and linear circuits, monitoring of operating modes, and measurement of bandwidth using a single unit. A basic generator (1) provides two frequencies. The signals (F1, F2) are added to the synchronising signal input (A) and the other input in two summers (A, B), whose outputs are subtracted in a subtractor (3). The subtractor output drives the synchronising signal output (K).

Title: Security system for bank - uses wireless signal to rotate drum and drop money into secure hidden space and replace with less or false money
Inventor: ERPELDING KARL HEINZ
IPC: E05G5/00
Filed: 1979-06-21
Abstract: The security system uses a signal transmitted via open space to replace the main store of money with a dummy store containing much less money. The main store and the dummy store are located on a drum that rotates about a horizontal axis. When thieves demand money the cashier operates a control that causes the drum to rotate thereby replacing the main store with the dummy store. The money in the main store drops down into a space beneath the drum. An arrangement of walls makes the money in the space inaccessible.

Title: Automatic transfer of yarn bobbins between machines - by means of a mobile carriage having mandrels with variable spacing
Inventor: DIESSNER GERHARD DIPL ING
IPC: B65H67/04
Filed: 1979-09-18
Abstract: A system of transferring yarn packages between machines, partic. bobbins of synthetic yarns from the winding-heads of a spinning machine to the creel of a stretch-twisting or stretch-texturising machine, has on a mobile carriage which can move the length of the winding frame, a series of mandrels mounted on swinging arms, which correspond to the spacing of the winding heads so that bobbins may be slid off the winding heads on to the mandrels of the carriage. At a transfer station, the bobbins are transferred to mobile creels by means of pushers activated by piston-and-cylinder units, after the swinging arms of the carriage have been moved to a new position in which the spacing of the mandrels carrying the bobbins is altered to correspond to that of the spindles on the creels. The transfer of packages between one machine and the next is completely automated, eliminating the need for manual handling of large and heavy bobbins.
