Title: Through bush insulator for HV cable - has conducting core with insulator and outer coaxial earthed conductor widening out inside liq. helium container
Inventor: DONON JEROME
IPC: H02G15/068
Filed: 1976-05-14
Abstract: The liquid helium container (200) high voltage entrant bush has a coaxial conducting core (22, 24). This core can be raised to a high electrical potential. An insulating sheath (28) surrounds the outer conducting core (24). Another coaxial conductor (32) surrounding the insulating sheath (28), is connected to earth. This ensures that the potential difference acts over the thickness of the sheath. Inside the container the diameter of the insulating sheath (28) increases till it reaches the end of the exterior conductor (32) whose diameter also increases in proportion. At the end of the exterior conductor (32) the insulating sheaths diameter increases further to form circular crown. The diameter of this crown progressively reduces to the end of the insulating sheath. The external conductor (32) covers the exterior of the insulating sheath up to the formation of the crown and finishes at the crown.

Title: Label application machine for box surfaces - prints labels and fixes them in position using two rotors holding labels by suction
Inventor: GRANCHER ROBERT EMILE LUCIEN
IPC: B65C9/14
Filed: 1976-04-29
Abstract: The labels are held in a reservoir (1). Underneath the reservoir is a rotor (7) provided with three suction plates (8) disposed equally around the periphery. A fork (3) having an up and motion (4) transfers labels between the reservoir and the suction plates, the rotation of the rotor being interrupted at the moment of transfer. As the rotor rotates, a marking roller (14) prints any required data onto the label as it passes. Underneath the rotor is another rotor (20), rotating in the opposite direction but with the same speed and also provided with three suction plates. The labels are transferred from one rotor to the other by suction and then pressed onto the top surface of the box (25) passing under the lower rotor at the same linear speed.

Title: Vibration of rubber reinforcement textiles during impregnation - with bonding agents, for increased coating penetration and application
Inventor: MAZIERES YVES
IPC: B29B15/12
Filed: 1976-05-14
Abstract: Impregnation of continuous filaments passing through a dip bath is enhanced by vibrating the filaments with direct impulses, viz contact with an oscillating bar. Specifically an array or mat of filaments is vibrated by a common transverse bar. Filaments leaving the bath pass round a hollow steel roll covered with silane rubber of 40 degrees Shore hardness and closed by polyamide end caps. The roll is in contact with a wiping roll which incorporates a chamber allowing the roll cover to be pressurised against the passing filaments. Used esp. for coating filaments with adhesion promoters prior to use for reinforcing rubber. Vibration enhances coating efficiency, esp. penetration between groups of filaments.

Title: Cooling system for lorry - with large dia. fan in housing above and behind cab to blow over angled radiators
Inventor: HAUSER KURT
IPC: B60H1/00
Filed: 1976-07-12
Abstract: The rear of the cab is fitted with a special housing (1) in which a large dia. fan (2) rotates about a horizontal, longitudinal axis. The fan extends over the level of the cab and draws in cooling air to blow down over a spreading grille (16) and from there over angled radiators (3), at the bottom of the housing, and with the warm air expelled to either side of the cab. The system provides a much quieter cooling system to reduce the lorry noise level. It can cool not only the engine but can also serve to cool the heat exchanger for a cooling/air conditioning system for the cab and the load.

Title: Transmission system for DC signals - uses auto-pilot oscillator to provide frequency proportional AC signal
Inventor: GILSOUL PAUL JEAN-LOUIS
IPC: H02M3/337
Filed: 1976-11-05
Abstract: The transmission system for DC signals uses an auto-pilot oscillator (C, C'), which supplies an AC signal, of a frequency proportional to the amplitude of the DC signal.

Title: Coolant circulation pump for pool type nuclear reactor - incorporates gas-filled bell enclosing submerged motor and flywheel, minimising shaft length and flywheel size
Inventor: LECOMTE ROBERT
IPC: F04D29/60
Filed: 1977-04-21
Abstract: An appts. for circulating a liq., pref. water, in a nuclear reactor of the pool type incorporates a motor, an inertia fly-wheel and a pump connected to the motor by a vertical shaft. The pump is in the lower, vessel part of the reactor and the motor is in the upper, pool, part, the parts being sepd. by a horizontal partition, with an orifice through which the shaft passes. The motor and the fly-wheel are in the pool part, in a bell-shaped structure, open below. The lower opening is vertically over the orifice and closed by a support plate. The motor and the fly-wheel are in the upper part of the bell and the support plate is fixed on the partition so as to be fluid-tight. The arrangement avoids problems which arise with existing ways of mounting the motor. These include placing it above the surface of the water, in which case the shaft has to be very long, or putting it and the fly-wheel under water, in which case the fly-wheel has to be large, or using a magnetic coupling, which is not economic and is less reliable. The arrangement allows easy dismantling of the pump part.
