Title: Electric machine speed control - switching circuit based on free running oscillator for DC/AC conversion
IPC: H02M7/515
Filed: 1973-04-11
Abstract: The circuit consists of a principal three phase bridge of thyristors connected to the supply, a three phase thyristor bridge for switching and a supplementary single phase bridge across which is connected the switching capacitor. The anode point of the single phase bridge is connected to the cathode point of the three phase switching bridge with an inductance and a diode connecting this common point to the positive supply connection. The reverse connection to the two bridges is brought out to the negative rail. Reverse current diodes in the three phase section ensure reciprocal compensating of reactive power.

Title: Appts. for putting caps on gas bottle outlets - cap positioning device abuts pivoting arm detecting level of outlet
IPC: B67B3/26
Filed: 1973-05-29
Abstract: The apparatus applies caps to the vertical outlets of valve heads on compressed or liquified gas bottles which are conveyed by turntables able to position the outlets in the correct vertical plane. Reciprocable within this plane is a head which carries a pair of arms pivoting about an axis perpendicular to the plane. The arms have curved ends such that on contact with the valve head the arms pivot and correctly position a vertically moving head carrying the caps. The latter head is reciprocated horizontally and has pairs of jaws which compress axially extending arms of the cap around the outlet and secure a locking ring, the ring being cut from an annular extension at the head of the cap and moved over the arms.

Title: Device to separate flat circular objects - has conical rotating surface with opening and stationary deflector plates
IPC: B65G47/14
Filed: 1974-02-05
Abstract: The objects are loaded in bulk into a conical upper cover (8) attached to a stationary cylindrical casing (7). A rotor (2) supports a conical surface (18) with at least one opening (20). Objects passing down this opening are discharged via an opening (14) in the casing (7). Stationary deflector plates are attached to the casing and are spring loaded to press against the top of the rotor. A geared motor (26) drives a wheel (32) which drives the rotor by friction. A torque-sensitive device in the drive causes an electrical contact to close when there is excessive torque, starting a reverse rotation procedure. The device can be adapted to handle non-circular objects.

Title: Pulse controlled linear DC electric motor - has electromagnetic poles moving either side of rail with spaced magnets
IPC: H02K41/02
Filed: 1974-02-06
Abstract: The guide track (1) for this linear motor system is made from non-magnetic material and has permanent-magnet poles at a suitable pitch along its entire length. The electromagnets (3) which form the inductor poles are located in the mobile part of the motor.

Title: Positive displacement rotary pump, partic. for winemaking industry - has rotor protected by renewable sleeve of elastomeric material
IPC: F04C2/46
Filed: 1974-09-18
Abstract: A positive displacement, rotary pump has a single rotor in a housing of circular cross-section with a discharge value fitted in the pump outlet. The pump may discharge to a grape harvest hopper fitted with a screw feeder delivering into the pump inlet. The rotor body is made of a (semi-) rigid material with its external working surface covered in a sleeve of flexible material, e.g. an elastomeric material such as natural rubber. Pref. the rotor housing cavity is fitted with a renewable, stainless steel liner, firmly keyed and bolted to the housing. Used for pumping liqs. carrying suspended solid particles, esp. grape harvest for wine making. Solid particles trapped between rotor and housing can be bedded into the flexible sleeve temporals until a clear path to the pump outlet becomes available, thus avoiding possible damage to rotor and housing. If a rotor sleeve or housing liner eventually does become damaged or badly worn, it is easily renewable.

Title: Liquid sprayer actuated by gas pressure - has gas delivered tangentally to cavity in body
Inventor: DENIS MICHEL
IPC: B05B7/10
Filed: 1974-11-25
Abstract: The liquid fuel burner sprayer projects the liquid in a plane, and has a body (1) with a flat outer face (3) in which there is formed a round cavity (2) whose axis is perpendicular to the face. Gas pressure supply passages discharge tangentially into the cavity, while the liquid is delivered to its base through an axial passage (16). The sidewall of the cavity is connected tangentially to a recess (18) coaxial to it, and is in turn tangential to the flat outer face of the body. The cavity can be of conical or curved section, the curve in the latter case being tangential to the outer face.
Patent FR-2255107-A1 (FR)
IPC: C02F1/24
Filed: 1974-12-20
Abstract: 1490227 Flotation apparatus; dispersing gases in liquids PIELKENROOD-VINITEX BV 6 Dec 1974 [22 Dec 1973] 52771/74 Headings B1C B1D and B2H A method of separating suspended material from a suspension comprises reducing the pressure of a pressurized liquid containing gas or a volatile substance to form a dispersion of gas bubbles in the liquid, and introducing the liquid into a tank containing the suspension and forming part of a plate-type separator 7 so that the bubbles become attached to the suspended material and cause it to float. In the embodiment shown the suspension is introduced to a chamber 3 through a duct 11 and a nozzle 12, the latter consisting of a tube having a longitudinal slot. A pump 16 draws in air through a pipe 18 and liquid through a pipe 17 and produces a pressure in a pipe 14. This pressure is suddenly relieved beyond a valve 15 to produce a dispersion of air bubbles in the liquid which is injected into the chamber 3 through a nozzle 13. Floating material passes over a weir 5 into a discharge chamber 6 and sediment is collected in a hopper 10 after passing through an assembly 7 of superposed parallel corrugated plates. In another embodiment, Fig. 3 (not shown) there are separate pumps (16) and (21) for the liquid and air which may be stored under pressure in a mixing vessel (22) before passing through the valve 15. The suspension to be treated and the dispersion of gas bubbles in the liquid may be introduced into the chamber 3 through the same nozzle, and in another modification the suspension itself is pressurized and mixed with air to form the dispersion of gas bubbles. The suspension may be subjected to a coalescence treatment in a device located either inside or outside the chamber 3.

Patent FR-2303986-A1 (FR)
Title: Automatically latching hook for safety harness - has spring loaded closing link latched by spring loaded pin when shut
IPC: F16B45/02
Filed: 1975-03-14
Abstract: The hook (1) is made from thick sheet material and the spring (24) loaded closing link (2) is made of thinner material formed in a narrow U in cross section. The internal width of the U is slightly greater than the thickness of the hook so that when pivoted (3) on the hook, the latter can slide inside the U. At the end opposite the pivot, the base of the U is cut back to form two projections (25) which pass on either side of the hook and prevent the closing link being bent laterally, accidentally freeing the webbing or rope.
Patent FR-2303968-A1 (FR)
Title: Rotary horizontal axis generator - has hinged weights with moment of descending weights exceeding moment of ascending weights
IPC: F03G7/10
Filed: 1975-03-14
Abstract: The machine consists of a metal disc mounted on a horizontal shaft. Pairs of levers are mounted on pivots equally spaced around the disc with one lever of each pair on each side of the disc. Weights are fixed to the ends of the levers and so arranged that the levers are unbalanced. As the disc rotates the levers on the descending side are held in the horizontal position by bolts. On the ascending side the levers assum a vertical attitude. The moment of the descending weights always exceeds the moment of the ascending weights and so the rotation of the disc is maintained.
