Title: Remote control system receiver - has easily resettable address and function decoders consisting of slide switches and rotary latched position switch
Inventor: HUERLIMANN HANS
IPC: H02J13/00
Filed: 1976-10-21
Abstract: The application is related to remote control installations in which coded signals are sent out from a central control station and picked up, according to address, by the local receivers. Each receiver has a unique address which may be set in a variety of ways. Where ease of setting and subsequent resetting is desired this is achieved by the use of sliding switches. The receiver unit comprises a front panel with an address decoder (2) consisting of a number of slide switches (3) moving in slots (6) allowing, for example, three positions (+,0,-). Thus the address setting can be easily checked and equally easily altered. It also contains a function decoder (4) consisting of a multi-position, typically 24, rotary switch (5) with a latch at each position. The numbers (7) on the wheel are also displayed at the front of the panel.

Patent DE-2718851-A1 (DE)
Title: Pneumatically operated cable driven engine - has cables on reels rotated by pneumatic pistons and inertia forces
Inventor: KITZBERGER PAVEL
IPC: F15B15/06
Filed: 1977-04-28
Abstract: The engine has two pneumatic cylinders (B) with reciprocating pistons (R). Compressed air moves each piston in one direction. It pulls a cable (J) which is wound on a reel (K) and so causes the reel to rotate. The rotation of the reel is transmitted to the output shaft (Q) through gears (Z). An additional gear (D) on one reel ensures that the output shaft always rotates in the same direction. The inertia of the reels causes them to continue to rotate when the piston has reached the end of its movement and so rewind the cable. This also returns the piston to its initial position. An end position switch (N) then opens the air valve (C) to admit a fresh charge of compressed air to repeat the process.

Title: Switching control unit for explosive environments - uses low energy connections between push-button and controlled power circuits
Inventor: RUCHATZ ALFRED DIPL ING
IPC: G08C19/12
Filed: 1977-05-20
Abstract: The push-button control signal circuit is made intrinsically safe by being operated at a very low power level. The leads connecting it to the power circuit are monitored by one tone generator. Another gives the 'on' or 'off' commands. The commands pass to a logic unit and branch into two lines, one with a time delay. If the output relay has not responded within the set time the signal lines are short-circuited and the equipment locked out. Similarly, a fault in the lines also locks out the circuits.

Title: Sealing glass containers with foil type closure - applying both pressure and heat to closure via hydraulic medium and intermediate flexible layer
Inventor: ZIMMERMANN PETER
IPC: B65B7/16
Filed: 1977-12-06
Abstract: Containers made from a material which remains relatively rigid when heated, e.g. glass, are sealed using a foil type closure which is connected to the container's opening edge by the application of both pressure and heat. At least the pressure is supplied by the closure via a liquid. The heat for the sealing process is transmitted at least partially through the hydraulic medium which in turn conveys it to the heat sealing surface through the intermediary of a flexible intermediate layer.
