Title: Infinitely-variable pitch axial-flow fan - has ropes from sliding adjusting member passed round blade trunnions
IPC: F04D29/36
Filed: 1976-01-09
Abstract: The pitch of the axial-flow fan blades is infinitely variable, and they are pivot-mounted in the hub, which has an adjuster member coaxial to it and rotating with it. Connected to this member are components such as chains or ropes transmitting a force in one direction only. Each of them is connected to and passed round the corresponding blade pivot trunnion, so that sliding movement of the member causes the blades to turn. Each blade can be mounted in two bearings, one outside the other, in the radial direction, the chain or rope being attached between the outermost bearing and the blade proper.

Title: Clamping the slide of an umbrella frame laundry dryer - disc in slide, tilts under gravity to lock
IPC: D06F57/04
Filed: 1976-02-05
Abstract: A clamping arrangement for the movable slide of an umbrella-type laundry item drying frame, has in or on the slide a disc through which the support tube passes, and which, when the slide is moved, is aligned at right angles to the axis of the tube and has play relatively to the tube, whilst when the slide is in position, the disc lies in a plane diverging from 90 degrees across the axis of the support tube. The disc may be brought into position by means of a lever and/or a spring, with the lever possibly forming part of the disc. This provides a simple and cheap method of ensuring the correct tension on the wash lines, and securely fixing the plunger in position.

Title: Telephone call indicating system for persons with defective hearing - converts incoming electrical signal to actuate vibrating reed system on wearer's wrist
IPC: H04R11/00
Filed: 1977-03-08
Abstract: The telephone call receiving system is associated with a high frequency signal transmission circuit. This circuit has a call signal shaping circuit which generates a pulse cut off signal at a predetermined low frequency. This low frequency is less than the frequency of the call signal. A high frequency transmitter transmits the high frequency signal modulated by the cutoff signal. A high frequency modulated signla receiver circuit has a high frequency receiver (21) which detects the pulsed cutoff signal. The receiver circuit includes a tactile excitation system (23). The tactile system (23) generates mechanical vibrations at a low frequency modulated by the control signal detected by the high frequency receiver. The tactile excitation circuit (23) has an oscillator which is sensitive to the frequency of the mechanical vibrations. The circuit has a mechanical vibrator having a magnetic circuit and strips with a magnetic end which vibrate at the frequency. The vibrations are activated when the oscillator circuit induces a magnetic field in the magnetic circuit.

Title: On load transformer tap changer - has pair of antiparallel thyristors and decoupling relay in each load branch
IPC: H02H7/055
Filed: 1977-03-16
Abstract: The on-load tap changer is intended for multi-stage transformers.

In order to monitor the switching time of the relief contacts (11-14) each load branch has an associated relay (18, 19). The relay is actuated by the voltage applied to the thyristor pair (5, 6) of the respective load branch. Across the contacts (20, 21) of the two relays is connected a safety circuit (22), incorporating a relay with adjustable time delay. The design helps to detect interference in the mechanical switching.

Title: Heating system using a closed thermodynamic cycle heat pump - having four stages, used for heating buildings in driers etc.
Inventor: TRICHET JEAN
IPC: F25B1/10
Filed: 1977-06-17
Abstract: The stages in the cycle are compression, condensation, expansion and vaporisation-followed by recompression. The fluid used in the cycle is a non-azeotropic mixt. Each stage of the process is a multistage process to use the different condensation and evaporation characteristics of the various mixt. components. The heat removed from the mixt. as it condenses passes into a heating system. Heat for vaporising the liq. is taken from an external source such as the air, a stream or a lake. The use of the multistage process increases the system efficiency. It may be used efficiently where there is a big temp. difference between the hot and cold source. It is relatively simple in regard to the equipment needed and its control and regulation.
