Title: Machine for cutting blanks from cardboard, plastics or leather - has pressure plate raised and lowered by roller carriage
Inventor: BEDNAREK EDUARD
IPC: B26F1/42
Filed: 1977-03-18
Abstract: A machine for cutting blanks from corrugated cardboard, plastics, leather, etc, has a table (1) carrying a hardened steel plate (2). The steel plate (2) supports the tool (3) with a cutting edge formed from steel strip. The cardboard blank (4) is pressed onto the tool (3) by the pressure plate (5). The pressure plate (5) is a 3mm thick sheet of rigid PVC with one end attached to a steel cable (6). The cable (6) passes over a pulley (7) and its other end is attached to the carriage (8) of the pressure roller (9). As the carriage (8) pushes the roller (9) over the pressure plate, the cable (6) lowers the pressure plate onto the cardboard (4). After a blank has been cut the withdrawal of the carriage (8) automatically raises the pressure plate (5).

Title: Film cassette including supply and take=up chambers - uses film slots jamming e.g. plastic stop on end of backing paper for easy retrieval
Inventor: WEISS RUDOLF DIPL PHYS
IPC: G03B17/30
Filed: 1977-04-09
Abstract: A cassette is for roll film pref. with backing paper. The unexposed roll film (1) and backing paper (2) are wound in the supply chamber (3). Exposure is effected in the channel between the supply and take-up chamber (4). The channel (5) between the two chambers also forms the film pressure plate.

Title: Container fluid level indicator - uses illuminated rod at central position for min. inclination influence and observed through side window
Inventor: BROCKMANN HEINZ DIPL ING
IPC: G01F23/02
Filed: 1977-04-19
Abstract: An indicator for the fluid level in a container, esp. of oil in a gear housing or storage tank in an aircraft is designed for accurate indication of actual oil level irrespective of the inclination angle and at a suitable point of inspection. Column indicators are limited as to application position which presents difficulties in compact structures. A self-illuminating light rod is placed perpendicular to the fluid surface at a point in the container at which level variation is minimal as the container inclines. A float ring moves up and down the rod with the fluid level, and a window at a convenient location on the container wall permits observation of the level of the ring against a scale on the rod.

Title: Compressed air respirator inhaling valve - has springs acting in closing direction with optional opening direction operation
Inventor: LEHMANN KLAUS-DIETER
IPC: B63C11/22
Filed: 1977-08-05
Abstract: The inhaling valve for gas-operated breathing and diving gear can work either with negative or positive pressure. During negative pressure operation hook (18) is in the upper position lever (18) is fully operational and presses the arm (8) in a direction to close the jet opening on valve (5). Opening of the valve takes place during the inhaling cycle due to the combined action of negative pressure produced by the inhaling of the user and the gas pressure from the cylinder connected to screw connection (4). When the respirator should operate under positive pressure conditions inside the mask, as may be required in cases where keeping out toxic gases from entering the mask, shaft (17) is rotated from the outside into the other resting position swinging hook (18) into the lower position. By this movement flexing spring (12) is carried along and its pressure onto the arm (8) is reduced. Hereby the weaker flexing spring (13) is capable of shifting the arm (8) slightly in opening direction. Valve (5) is slightly opened and an increase of pressure inside the mask follows.

Title: Article printing method - comprises transferring print through colour solvent from paper to article
Inventor: ALBIEZ ERWIN
IPC: B41M1/38
Filed: 1977-12-23
Abstract: Colour or black/white prints are produced on articles, esp. those made of leather or wood by producing a printing plate with the original and transferring the print to a flexible carrier (granulated art paper). The article is wetted with a colour solvent and the printed side of the paper is applied to it. Pressure transfers the print to the article. This eliminates all difficulties with the instability and merging of colours. In the case of leather, it neutralizes the migration of tannic acid and ensures excellent durability. Complex pictures can be transferred satisfactorily. Pref. the printing plate is made by the offset printing method. The pref. print carrier is a granulated art paper. The colour solvent is a two-component mixt. of one part of a colour solvent without oil with four parts by wt. of a colour solvent with oil.

Title: Carrier wave communications system - sends frequency multiplexed analog signals and TDM digital signals in parallel
Inventor: POSPISCHIL REGINHARD DR ING
IPC: H04J4/00
Filed: 1978-01-27
Abstract: The carrier wave communications system sends in parallel analog signals by frequency multiplexing and digital signals by time multiplexing over the same pair of wires or a separate pair in the same cable. To prevent the analog and digital signals overlapping, the digital signal is modulated onto a carrier whose frequency is a multiple of half the bit frequency and sent in the main band as well as the lower band. The overlap in the lower band is suppressed.
