Title: Resistance wire winding for rotary winding type heater - uses circular former with resistance wire wound in radial loops round its circumference for improved heat transfer
IPC: H05B3/16
Filed: 1980-12-19
Abstract: The electric heater rotates the heater winding to improve heat transfer, rather than using a stationary winding with a fan forcing air through it, resulting in reduced dust disturbance and noise. The electric resistance winding is formed to resemble the petals of a flower. A circular, ceramic former (5) has its outer face formed as a crown with projections and slots formed to hold the resistance wire (3) which is looped round each projection then folded out in a radially long loop (4). The winding is formed round the entire circumference of the former and is connected either to a supply contact or to a further winding placed behind the first. The ceramic former has mounting holes (1) on its inner flange for attachment to a driven shaft.

Title: Helicopter with tandem rotors - has rotors angled so that front does not reduce lift of rear
Inventor: JUPE ROBERT JOHN
IPC: B64C27/08
Filed: 1981-01-13
Abstract: The helicopter with rotors in tandem, has the front rotor turning in the opposite direction to the rear. The dia. of the front rotor is smaller than that of the rear. The downwards deflection of the front rotor does not interfere with the tips of the blades of the rear rotor. The axes of the two rotors slope at an acute angle from the vertical, and in opposite directions from each other. The front rotor has fewer blades than the rear and is in the ratio of their dias. The front rotor may have three blades, and the rear rotor has four. They may rotate at different speeds and in inverse ratio to the number of blades.

Title: Shutter preventing heat loss from chimney flue - is edge hung or has rocking lever counter-weighted to remain open and operated by hand lever
IPC: F23L11/00
Filed: 1981-02-05
Abstract: The door (1) may be mounted on an intermediate axle (2) or edge hung, being used in a chimney flue to control heat emission. It is sited at eaves level or where the flue passes through a roof, being closed to prevent heat loss when the flue is not in use, and vice versa. The door may have a frame (5) in metal or ceramics and a peripheral air-seal (3) in moulded rubber or bristles, being opened by a hand-rod pinned to an edge. A counterweight (4) in a diametrically opposite position may apply a couple retaining the door in the raised open position. An alternative actuator uses a connecting rod from a radius arm to linked angled and straight rocking (9) levers in a sealed (11) side opening.

Title: Glass fibre mfr. - where several thermocouples are located in holes in fibre drawing die for accurate process control
Inventor: THOMPSON THOMAS KENT
IPC: C03B37/09
Filed: 1981-03-16
Abstract: The process and plant employ an electrically heated die, the base of which contains numerous holes through which molten glass is drawn downwards to obtain fibres. One or more temp. sensors, esp. thermocouples, are fixed to the base of the die to detect the temp. of the glass outlet holes. The thermocouples provide an electrical signal representing the temp. of the glass at a partic. outlet hole. If the glass temp. obtd. is outside a predetermined range, an interruption to fibre prodn. is indicated, and a warning signal or alarm is triggered. If the alarm is actuated, either the electric heating current fed to the die is reduced, or the speed of the bobbin winding the fibres into a thread is reduced, or the bobbin is stopped. Improved control of the fibre drawing process is obtd., using the temp. of the molten glass in one or more die outlet holes.

Title: Mounting device for car radio - comprises apertured plate and slotted bracket attached to control shaft extending behind dashboard panel
Inventor: COQUEREL PHILIPPE
IPC: B60R11/02
Filed: 1981-06-05
Abstract: The fastening for mounting a car radio in a prepared hole in the dashboard uses the two threaded sleeves (6) around the control knob shafts. Each sleeve passes through a hole in a plate (9) which is large enough to cover the entire aperture in the dashboard. On the sleeve there is a bracket (13) with a slot cut in it. The slot enables the bracket to be put into its final position after the nut (27) and washer (26) have been assembled on the sleeve. The bracket extends sideways and has a folded lip (20) which presses against the inside surface of the dashboard panel. The bracket and plate thus hold the dashboard panel between them. The plate (9) has a suitable slot near the hole through which the shaft passes to allow introduction of the bracket.

Title: Variable magnetic field influence proximity pick=up - has inductance of thin conductor bonded on magnetic strip placed in oscillator circuit
Inventor: HUEBER DIDIER
IPC: G01V3/08
Filed: 1982-04-21
Abstract: The magnetic sensitive proximity pick-up consists of an inductance, which is under the influence of a variable magnetic field, inserted in an electronic circuit having various components for realisation in partic. of an oscillating circuit. The inductance comprises at least one thin conductor of section less than 10 power 4 microns squared. The magnetic circuit comprises at least one thin layer of soft ferromagnetic material of thickness less than 100 um. Either the inductance or the magnetic circuit is plated to the other in as close a manner as possible. In one version the inductance is a conducting wire (1) which is glued in a zig-zag on a flat thin plate (2) having high magnetic permeability. The incident magnetic field (direction H or H') is produced by a permanent magnet or electromagnet. To make the proximity pickup the inductance is inserted in a two-input quadrupole integrated circuit (3,4,5,6), which generates signals whose frequency varies with the proximity of the incident field over a large intermediary range. A capacitor (7) adjusts the frequency of the oscillator in the absence of an incident field. Alternative versions include a hybrid proximity pick-up obtained by deposition of the conductor and magnetic material on a ceramic substrate, and an integrated proximity pick-up obtained by deposition of the conductor and magnetic material on a silicon substrate.
