Title: Fire prevention and cooling system for cable trunks - has channels carrying cables and collecting cooling water from overhead spray nozzles
Inventor: FRANCKE DIETHARD DIPL ING
IPC: A62C3/16
Filed: 1973-12-06
Abstract: The fire prevention and cooling system for cables and trunks in workshops etc. consists of a channel shaped to follow the path of the cables and to collect cooling water sprayed from nozzles above the cable. The cooling water is directed onto the cables and is collected by the channel which lies beneath the cable. The channel is in the form of ducting with dam walls across it at places, where it drops down to another level. The dam walls have holes at the bottom to allow water to flow from a higher to a lower level. The side walls of the ducting have overflow holes towards their top edges. The system can be adapted to vertical cables and to stacked horizontal cables.

Title: Short circuit protection of resonant choke converter - involves using difference between actual and permissible pulse duration as control
Inventor: KORN JOEL DR ING
IPC: H02H7/12
Filed: 1974-04-03
Abstract: The application is to power supplies derived from transistor controlled chokes operating at constant frequency, and giving energy transfer by means of core magnetisation. The maximum duration of the transistor conducting period is predetermined for maximum energy transfer through the coil. The actual pulse duration in operation is measured and compared with the predetermined value, and when the latter value is reached the converter is either switched off or prevented from giving a higher output. A suitable control circuit may contain an impulse generator for the maximum reference, and equate thig signal with one from the bistable oscillator controlling the converter in a comparator circuit whose output is used as an overriding control.

Title: Automatic regulation with on-off controller - is by integrating controller impulses in timing circuit
Inventor: FELLENBERG JOST VON DIPL CHEM
IPC: G05B11/16
Filed: 1974-04-22
Abstract: The method provides improved regulation of the temperature of central heating and air conditioning installations, which operates automatically while using an inexpensive on-off controller. The process consists in integrating impulses from the controller in a timing circuit so as to predetermine the output fed to the regulating equipment. This comprises an expansion vessel and bellows which are filled with an expanding medium. Electrical heating for the vessel is fed by an on-off regulator through a thermally sluggish resistance, which stores heat gained by impulses from the regulator. When the on-off regulator is off, the expanding medium in the vessel cools and the valve is closed whereas the resistance cools very little.

Patent DE-2434118-A1 (DE)
Title: Control valve for windscreen washer jet - with manual release to allow air to vent from pressure side of pump
Inventor: BLEGER CLAUDE
IPC: B60S1/48
Filed: 1974-07-16
Abstract: The windscreen washer jets are separated from the pump by pressure control valves (19) which ensure that the jets operate above a set minimum pressure, to prevent dripping etc. If the pump drains the water reservoir and fills the water pipes with air then the pump cannot compress the air sufficiently to open the valves. The valve is therefore elbow shaped with a plunger attached to the valve element leading out of the valve. Operating the plunger manually primes the pump after the reservoir has been replenished.

The pipes are connected to their respective carburettor air intakes via a centre aperture in a disc which has a number of concentric grooves to permit fitting to different sized intakes, a second disc having a number of slots fits over the first disc to provide a scale by which the air feed to the carburretor is adjustable.
Patent DE-2447844-A1 (DE)
Title: Monitor lamp driving circuit for telecommunication display - has panel which consists of integrated circuitry which drives a display lamp in two flashing and one static modes
Inventor: KORN JOEL DR ING
IPC: H04J1/16
Filed: 1974-10-08
Abstract: The monitor lamp driving circuit is for use in telecommunication monitor panel equipment, and consists of integrated circuitry, which can drive the display lamp in several useful modes. Integrated circuit logic NAND gates are used. The circuit is required to light a display lamp in a fast flashing mode when a fault occurs, steadily after a test switch is closed, and the fault remains, in a slow flashing mode when the fault is cleared, and to extinguish the lamp which the test switch is opened. This is achieved by applying fast and slow clock signals (T1, T2) to NAND gates (G5, G6) the other inputs of which are suppled from a flip-flop consisting of two further NAND gates (G1, G2). The flip-flop is driven by the appearance of a fault condition into a state which gates the fast clock pulses on to the base of a transistor (TS) which then flashes the lamp. A test switch input (Q) reverses the flip-flop state and leaves the lamp lit. The clearance of the fault gates through slow clock (T2) and flashes the lamp slowly, whilst the removal of the test switch input (Q) extinguishes the lamp if the fault is cleared.

Title: Tensioning mechanism for tennis rackets - has helical spring spindle running inside frame with milled tightening collar
Inventor: RICHTER HERBERT
IPC: F16B7/06
Filed: 1974-11-11
Abstract: The design is for tennis rackets with interchangeable frames and is claimed to be easily operated compact and cheap. The tensioning mechanism consists of threaded rods or coil springs (12, 13) held by a milled collar (14) that is operated by hand. The threaded rods or springs fit inside the frame (1) which typically has an oval cross section and operate against a threaded bush (10). There is a central holding rod for the spring with a spherical holding boss at each end. This serves to prevent the spring expanding and jumping out of the sleeve. The strings (7) are held by pullers (5) that fit inside the racket frame.

Title: Dry window cleaning block - steel wool pad attached to holder of soft material
Inventor: ALBERER ALOIS
IPC: A47L13/04
Filed: 1974-11-21
Abstract: A window cleaning block comrises a steel wood pad (1) which is fastened to a holder (2) which is designed as a handle of soft preferably sponge-like material. Neither the sponge holder (2) nor the steel-wool surface have to be wetted prior to use, even when cleaning dry glass panes. The soft holder preferably protrudes beyond one or more of the side edges of the steel wool so that for example when cleaning windows the frames are not scratched by the steel wool. Since the glass is cleaned in the dry state the cleaning time is reduced by not having to rinse the windows clean.

Title: Optical system for endoscopes with inclined field of view - has extremely small external diameters
Inventor: YAMASITA NOBUO
IPC: A61B1/00
Filed: 1974-12-10
Abstract: The system has a prism to deflect the light from the object to a lens, and an image transmitting device. The entrance surface of the prism defracts the light from the object. The entrance, reflecting and exit surfaces of the prism are arranged in such a way that the light passing through the entrance surface is reflected by the reflecting surface back onto the entrance surface, reflected again by the latter and projected through the exit surface onto the lens. The angle of the prism at the entry surface is related to difference between the entry and exit angles by a trigonometrical expression.
