Title: Low cost artificial brick - made from fine sand, binder such as aluminous cement, pigment and an accelerator
IPC: C04B28/06
Filed: 1975-06-04
Abstract: In the mfr. of articificial stones, the novelty is the mixing of (1) fine sand; (2) a binder such as aluminous cement or pure calcium aluminate; (3) a mixing liq.; (4) a pigment chosen to give the required colour; and (5) an accelerator, e.g. LiCl. The mixt. is immediately cast into a mould and vibrated manually or mechanically, then left 3.5-4 hours, followed by removal of the moulding which is treated with silicones by immersion or spraying. The process is pref. employed to produce a new industrial brick with size 40 x 8 x 1.5 centimetres. The new brick has an excellent appearance and high strength, with an impermeable surface. It can be rapidly produced by mass prodn. methods.

Title: Mine truck handling system - has hook engaging eye in truck body with hoisting by hydraulic ram with pulley at end of rod
IPC: E21D9/12
Filed: 1975-06-25
Abstract: The lifting and handling mechanism is particularly for vehicles in underground mines, and when tunneling. It has a lifting mechanism for empty trucks, mounted on a support fixed to a fitting positioned in the tunnel near the working face. This allows full trucks to pass through, while the face is quickly supplied with empty ones. Lifting can be effected by a hydraulic ram (5) suspended at one end of the fitting. A hook (15) engages with the empty truck (16), and the hoist rope from it (10) is reeved round a guide pulley (13) in the roof, a further pulley (9) on the end of the ram rod, and back to an anchorage (14) near the guide pulley.

Title: Safety device for electrical machining appts. - includes a secondary current generator and cut-off switch
Inventor: POTHIER GUY
IPC: B23K9/10
Filed: 1975-12-15
Abstract: Safety device for an electrical machining appts., esp. for welding or cutting, operating in wet conditions or under water, comprises a main current generator supplied with polyphase AC and delivering DC to a user circuit having >=1 electrode and a workpiece. A cut-off switch is included in the supply circuit of the main generator. An auxiliary DC generator having an-external static horizontal characteristic is provided. This generator has an exit voltage Tg Tv the exit voltage of the first generator; and of value 0-24V. Its exit is connected in parallel to and in opposition to the exit of the main generator. Detectors for the electrical characteristics of the current supplied from the main generator and of the current circulating in the user circuit are avoided. The appts. includes a comparator, sensitive to Tg, the output voltage of the auxiliary generator, and a reference voltage. The appts. includes a command unit for the circuit switch which is sensitive to changes in the detectors and to the comparator, and equipped to provoke opening and closure of the supply circuit as a function of those characteristics and the exit voltage. Large variations in the applied voltage according to whether the workpieces is close to the electrode or not are not required.
Patent FR-2338863-A1 (FR)
Title: Thermoplastic bottle with welded-on metal seal - notched at the neck, so that an imperfect weld will easily reveal itself
IPC: B65D1/02
Filed: 1976-01-22
Abstract: Thermoplastic bottles are closed at the neck with a metal seal held in place by thermoplastic welding. The neck of the bottle is notched. The weld must then go deep enough to take the seal to the level of the bottom of the notches; failing this, a notch will be left open, and a test of the bottle by trying to pour out its contents will reveal the faulty weld. This is a protection against faulty machine action for bottles with corrosive contents, and as preventing the detachment of loosely fixed duty-paid seals for fraudulent re-use.
Patent FR-2349303-A1 (FR)
Title: Inclinable front hinging seat for water closet - has hand lever and springs assisting seat inclination and helps aged on infirm to lift themselves
IPC: A47C7/56
Filed: 1976-04-29
Abstract: The front-hinging pivoting chair seat (5) is designed to assist the aged or infirm in raising themselves to the standing position when leaving the seat, and is partic. suitable for application on w.c. seats. The seat (1) includes levers (M) which are used by the occupant to incline the seat, and upward seat inclination is assisted by built-in counter-springing (R). When the seat (S) is unoccupied it may have a light forward inclination (S1) under the effect of the springs (R). The springs (R) are compressed under the weight of an occupant and the seat may adopt a horizontal position (S2). The hand levers (M) pass through the seat (S) hinge (2) and, thus, with the seat (S) form an 'L' shaped member in side elevation. The seat may be built onto a chair structure (1) or be a portable unit.
Patent FR-2352171-A1 (FR)
Title: Adjustment device for pinion of engine starter motor - has tab washer held against adjustment nut by spring, requiring axial force against spring for adjusting pinion axially
Inventor: MATASE EUGEN
IPC: F02N15/00
Filed: 1976-05-18
Abstract: The pinion of the engine starter motor is moved in and out of engagement by the lever (7) which is actuated by the solenoid (2) and the bolt (1). The bolt (1) is provided with a sleeve (3) forming a slide for a tubular member (b). The tubular member (b) is provided with a screw thread which engages the nut (6) which is provided with bosses which engage slots in the lever (7). The tubular member (b) is normally prevented from rotating by a tab washer (d) which is pressed against its hexagonal end by the spring (8). In order to adjust the axial position of the starter pinion the tab washer (d) is pressed against the spring until it is clear of the hexagon so that the tubular member can be screwed in or out of the nut.
Patent FR-2359630-A1 (FR)
Title: Machine for producing and pumping a paste - from a liquid and a powder using one motor for all operations
IPC: B28C5/12
Filed: 1976-07-28
Abstract: The machine comprises a hopper for the powdered material which feeds a mixing column, which is also supplied with water. The mixing column has a drive motor at the top to rotate all the internal moving parts. The mixing column is joined, through a unit at its base, with a pump. This pump is parallel to the mixing column so that the paste product is subjected to a directional change of 180 degrees between mixer and pump. The speed of rotation of the mixer and pump can be adjusted independently of each other, thereby offering a variety of combinations which can be suited to the products used. The arrangement of the pump relative to the mixing column and the resultant directional change results in an increase in the mixing time and also ensures that the pump only receives a quantity of paste corresponding to its suction capacity, thus eliminating any risk of overloading.
Patent FR-2360965-A1 (FR)
Title: Three=phase submarine electrical cable - uses thin steel strip protective cover to guard against damage by fishing boats
Inventor: PIERRE BERNARD
IPC: H01B7/22
Filed: 1976-08-05
Abstract: The three phase submarine cable has three cores in trefoil formation each being surround by a semi-conducting screen. Around the screen (2) is a thermoplastic insulant (3) and around this insulation is a further semiconducting screen (4) of the same type as the first screen (2). An electrostatic screen (5) of copper surrounds the second semi-conducting screen (4). The three electrostatic screens are tangential to each other in pairs. Surrounding the trefoil group is a textile band (6) and between the gaps between the cables and the band (6) are plastic fillers (10). These fillers (10) encase steel cables (7, 8, 9) which take the longitudinal tension exerted when the three phase cable is being lowered into or lifted out of the water. Over the textile band (6) is a thin steel strip guard (11) and over this is a thermoplastic sheath (12).

Title: High speed machine bearing - has discs with radial holes to eject air during starting and liquid when at speed
IPC: F16C32/06
Filed: 1976-12-17
Abstract: The stationary shaft is surrounded by a sleeve (5) forming part of a rotor. The shaft has a number of discs (3) with radial holes which eject liquid by centrifugal force so that it forms a liquid ring in the annular space (8). When the rotor is stationary, it is supported by the tapered rings (9). On starting, air is supplied through the hole (2) so that the rotor runs on an air bearing. The inner ring (9) is then moved axially and liquid supplied through the discs (3). Rings of high pressure liquid are generated in the space (8) due to centrifugal force and these liquid rings support the rotor (5).
