Patent FR-2251116-A1 (FR)
Title: Gas-isolated HV line - is embedded in concrete heat exchanger near tubes carrying heat-removing fluid
IPC: H01B7/42
Filed: 1974-08-06
Abstract: The h.v. line consists of three phase conductors supported inside a steel tube filled with SF6 at 4 bar. The steel tube is surrounded by a concrete block that acts as a heat exchanger. Heat removing tubes are embedded in the concrete and carry a gas or liquid, e.g. water or oil, that removes the heat from the concrete. These heat removing tubes are made of steel, ceramic or asbestos cement and, where more than one h.v. line is embedded in the concrete, are situated symmetrically between the h.v. lines and have the same thermal conductivity to avoid hot spots.
Patent FR-2284243-A1 (FR)
Title: Power switching between oven heating elements - by bimetal strips controlling members alternately powering elements
IPC: H02J3/14
Filed: 1974-09-05
Abstract: The cyclic switching system provides electrical power alternately to each of two heating elements (1, 2) which may have nominally equal consumptions or may be different or variable. Each element is fed from a two way switch (3) controlled by a bimetal thermostat (6, 7) such that the current through one element and the bimetal strip causes the switch to operate, the other element plus strip then being switched in and vice-versa. a thermostat (4) in series with the common supply line to both elements provides overall temperature control of the oven.

Title: Device to deliver blister packages from a hopper - moving hopper bottom operates moving side points to control number of objects
IPC: B65B43/44
Filed: 1974-10-04
Abstract: The objects, typically packages formed by pieces of cardboard with a plastic covering film, arrive on a conveyor (1) and fall into a hopper (3) formed by sides (4) and end pieces (9, 11). The spacing of the sides and ends is adjustable. The bottom of the hopper (18) with an attached pushing plate (19) can be moved backwards and forwards by an actuator (20). In the rearwards position the bottom of the hopper is open, permitting objects to fall on to a lower plate (17) from where they are pushed on the forward stroke. The number of objects falling through is controlled by points (32), adjustable for position, and movable in a lateral direction, which are operated by rollers (29) running against the sides of the hopper bottom (18).

Title: Screwless clamp for tool of folding press - hydraulic cell forces C-shaped jaws on T beam together
IPC: B21D37/04
Filed: 1974-11-07
Abstract: Screwless rapid clamping of tool or workpiece utilizes hydraulic jack cell to force jaws together. Typically two C shaped jaws are fixed on opposing sides of the web of a T beam via horizontal bolts, their top legs bearing on the vertical faces of the T flange of the T and lower legs pressing the tool onto the web. The bolts also contain a vertical counter plate which bears via a load cell onto the back of one of the C jaws. Thus cell expansion tensions the bolt forcing the jaws together. Pref. cells are energized from a hydraulic master cylinder-piston arrangement with a calibrated spring controlling maximum hydraulic pressure.

Title: Steam turbine process using diphenyl - has wet vapour fed to each stage, to give saturated state after expansion
IPC: F01K7/34
Filed: 1975-01-21
Abstract: Steam turbine process for diphenyl has wet vapour fed to each turbine stage with a liq. content such that after expansion it reaches a saturated state. Preferably, the wet vapour is formed by feeding liq. medium to each stage; the liq. is sprayed or atomized, and may be introduced into the saturated vapour of the preceding stage before or in the guide vanes. The liq. fed to the stages may be preheated, with tapped-off vapour or in mixture condensers. The excess press. required for infeed of the liq. into the saturated vapour is derived from the pump stages required for stepwise increase of press. of the feed liq. Use of the temp. drop is improved.

Title: Holographic recording of information presented as electrical signals - involves convergent spherical object wave and astigmatic reference wave
IPC: G11C13/04
Filed: 1975-01-29
Abstract: The apparatus as in 2355683 is used for halographic recording and reproduction of information presented in the form of electrical signals, and astigmatic reference and object waves are used to increase packing density. Improvements to the apparatus provide a process which enables the equipment required for reconstructing the information from the hybrid hologram to be simplified. The new process uses a convergent spherical object wave and an astigmatic reference wave whose horizontal focal line is in the same plane as that of the object wave, while its vertical focal line mirrors symmetrically the plane of the object wave.

Title: Paying in position for banks - has drawers controlled by cashier avoid exposure behind protective screen
IPC: E04G7/00
Filed: 1975-04-24
Abstract: Two drawers are let into wells in the counter. Each is mounted on slides and has a rack engaging a crown wheel fitted to a handle on the cashier's side. Turning this 180 deg. each way brings each drawer, alternately, on the customer's and the cashier's side. Automatic locking is done beneath the counter surface by the handle (5) having two arms (7, 8) engaging plates (13, 14) on the drawers. When one drawer is locked, a spring loaded plunger (19, 25, 20, 26) holds a catch (21, 22) behind a dog (23, 24) on the plate (13, 14). The other drawer is then unlocked by a projection (28) on a cam plate (27) pushing the plunger aside.

Title: Rapid two-stage moulding of small cured (rubber) parts - by shaping at ambient temp. and post curing using very hot tools
IPC: B29C45/14
Filed: 1975-06-11
Abstract: The process comprises (a) pressing a preform of the material at ambient temp. and (b) shaping and curing the preform in profiled press tool preheated to just below the degradation or decomposition temp. of the material. The process is esp. suitable for moulding small seals or ribs etc. onto other components. The preforms may be applied to a supporting surface via stencil screens. No excess material is moulded and cured. By sepg. the spaping and curing operations, the curing tool may be run at much higher temps. There is no risk of premature set-up during shaping, and the higher temps. reduce curing periods. Preforms may be made by transfer moulding without spoiling the material in the reservoir and runners. Energy is not wasted in swinging tool temps. between hot and cold.

Title: Fluid pressure transducer with two compartments - with one compartment in hollow body connected to monitored pressure and other to reference
IPC: G01L9/00
Filed: 1976-05-12
Abstract: In a fluid pressure transducer the compartments include a common wall which is deformable in response to variations in the pressure of the first fluid source as compared to that of the reference source, and received within the body are a carrier and a first abutment member which are capable of relative movement towards and away from one another in response to deformation of the common wall. Further abutment members are resiliently supported by the carrier and arranged so as to become engaged with or disengaged from respective portions of the first abutment member at different positions of the first abutment member relative to the carrier. Thus in use the number of further members engaging the first member varies in accordance with variations in the pressure of the first fluid source as compared to that of the reference source.

Title: Drive boost for gas blast circuit breaker - uses differential piston to compress quenching gas to high press. for arc quenching
IPC: H01H33/75
Filed: 1977-04-20
Abstract: The quenching gas flow is produced by a compression device during switching off. The quenching gas in the circuit breaker is compressed in a compression chamber (2) by the face (1a) of a differential piston (1). The high compression causes the quenching gas to flow in the direction of the light arc. At least part of the quenching gas, heated by the light arc, is expanded in a quenching gas expansion chamber (6). Thus the other face (1b) of the piston ana at least a part of the chamber boundary (6a) are moved apart. This fraction of the quenching gas is drawn off towards the end of the switching off from the expansion chamber to the quenching chamber of the circuit breaker surrounding the compression and expansion chambers.
