Title: Earth drilling method for piling etc. - uses vibrating head in compressed air shield leading casing to maintain seal
IPC: E02D3/10
Filed: 1974-02-18
Abstract: Mode of construction of vertical sand drains, consolidated column or mass concrete piles, claimed to be superior to jetting, driving or plug to jetting, driving or plug driving of casings in that it is a dry process and prevents ingress of subsoil into the casing, using a vibrating bullet shaped head (9) in a bell shaped compressed air shield (2) to precede the casing as it penetrates the subsoil. Once the required depth of penetration is achieved the void is filled with the replacement material (5) and the casing progressively withdrawn. The compressed air effect is maintained throughout the process to compact the infill and again prevent ingress of subsoil and ground waters. A shoe of filter media or precast concrete can precede the vibrator for gravel etc or concrete filled piles respectively.

Title: Lightweight plaster building block with heating element - has element in integral reinforced wall
IPC: E04B2/02
Filed: 1974-07-05
Abstract: The lightweight plaster tile or building block has steel mesh reinforcement enveloping the lightweight aggregate core. This mesh serves to confine the aggregate during plaster pouring and as an electric heating element in the finished block. The mesh also permits binder flow from skin veneer areas into aggregate interstices, thus obviating previous three-stage pouring processes. The block incorporates two outer parallel veneers of plaster sandwiching the lightweight core, with the mesh layers locating in the veneer to core interfaces. Electric circuitry components and supply wires connect the heating elements. Insulating plates and sheathing sections are included in the final wall assembly.

Patent FR-2302194-A1 (FR)
Title: Mould press locking system with adjustable stroke - to minimise travel during locking or parting
IPC: B29C45/67
Filed: 1975-02-28
Abstract: Press assembly for supporting injection moulding tools on platens both of which are traversed by tie bars which transmit the forces applied by the hydraulic rams for locking/parting the moulds. The tie bars feature two or more circumferential channels which are aligned and which can be engaged by clamps to vary the distance between the two platens, when the press is fully open. The travel of the high pressure ram is greater than the distance between adjacent channels on the tie bars, allowing the ram to be set so that channels can also be engaged when the press is just closed. The press can be adjusted to accept mould tools of various depths. Proper relative adjustment of the locking force rams then means that the minimum of tram travel/oil transfer is necessary prior to developing high moulding locking/parting forces, thus minimising cycle times and the motions and wear of the high pressure system.
Patent FR-2266135-A1 (FR)
Title: Rotary heat-exchanger storage mass carrier - with gap between sheath double walls permitting deformations and heat expansion
IPC: F28D19/04
Filed: 1975-03-24
Abstract: In the heat-exchanger, the storage mass carrier, usually in the form of a rotor, comprises a central shaft with sector cages fastened to it accommodating the storage mass, with high-differential-temperature fluids passing through and transmitting heat from the hot to the cooler fluid, normally leading to rotor deformations, leakages and loss of efficiency. The radial partitions dividing the mass carrier are connected to a sheath which is double-walled, with an intervening gap between these walls large enough to allow unhindered deformations of the outer sheath wall and heat expansions of the inner one, against which the storage mass may be closely packed. Harmful heat expansion effects are minimised.

Patent FR-2335121-A1 (FR)
Title: Reduction of power consumption of discharge lamps - uses addition of impedances to lamp circuit to vary arc voltage
IPC: H05B41/40
Filed: 1975-10-14
Abstract: The method consists of progressively varying the circuit impedance during lamp operation. To do this it is sufficient to divide the total impedance into two or more impedance and to insert them in circuit at different times. The increase in arc voltage is much less than that due to the added impedance. A time delay between each impedance gives the lamp time to reduce, after a small instantaneous addition increases its arc voltage. This lowers the value with respect to the initial position and extinction is avoided. A lamp having an arc voltage of the order of 135 volts. increases by instantaneous amounts to 150 volts. or more if the added impedance is such that the power reduction required is 20% to 30%. The circuit for power reduction is designed to permit its location in the lamps housing.

Title: Lockable roller-type shutter - has rope drum sliding on shaft with teeth engaging with others on housing
IPC: E06B9/86
Filed: 1975-11-28
Abstract: The shutter rolls up onto a shaft in a housing and is lockable in the shut position, comprising a number of parallel cross-bars assembled into a roller blind, also a pull rope. One of the housing sidewalls (3) has a set of teeth fixed to it (W), and corresponding teeth (Z) on the rope drum (6) form with these fixed teeth the locking mechanism. Pulling on the rope causes the drum to slide along spiral spines in the axial direction and thus release the mechanism. The drum teeth with their coupling member (8) are coupled to the shutter drum (1) in such a manner so that they cannot rotate in relation to it, but can slide for a limited distance in the axial direction.

Title: Pipe coupling for flexible metal pipes - has double O=ring seal to permit relative rotation between pipes
IPC: F16L27/08
Filed: 1976-08-13
Abstract: Flexible metal pipes with helical corrugations are unable to resist torsional loads. To prevent such loads being imposed on the pipes a coupling permitting relative rotation between two sections of pipes is used. This coupling consists of a fitting (1) with a screw thread (2, 3) at each end. The corrugated pipe (6) has a coned nut (7) which presses the flanged end (6a) against a sealing washer (4) and is clamped by the outer nut (8). A pipe connector (9) has two O-rings (13) in grooves (12) and is held in the bore of the fitting (1) by the coupling nut (11). The nut (11) permits relative rotation between the connector (10) and the fitting (1) and so prevents any torsional load being exerted on the flexible pipe (6).
