Patent FR-2270709-A1 (FR)
Title: Rotation control device for sync motor permanent magnet rotor - prevents permanent rotor rotation in wrong direction by field plate arrangement
IPC: H02K7/118
Filed: 1974-05-06
Abstract: A pinion (50) is mounted to rotate about the rotor (16). The rotor carries a stop (68), and a wedge arrangement (70) is used for releasable connection of the pinion to the rotor. In this connection the pinion has a preset rotary freedom in relation to the rotor. The pinion meshes with a drive gear (54) which carries an engagement element (72) for resting against the stop if the rotor rotates in wrong direction. The drive gear has a channel (82), spaced from the engagement element, through which the stop can move without hindrance when the rotor rotates in correct direction. Preferably the stop is in the form of a pin (74), protruding from the rotor surface. The engagement element may be formed by a lug protruding from the drive gear surface.

Title: Hot water supply system operated from central heating supply - has heat exchanger reservoir passing hot water coil
IPC: F24D3/08
Filed: 1974-10-02
Abstract: The boiler (1) supplies hot water to the space heating radiator system (4) through the pipes (3) and (6) and the accelerator pump (5) in the main circuit. The return water passes through a three way valve (10) which supplies water to a heat exchanger reservoir (11). The water returns from the heat exchanger to the boiler through the pipe (13). The three way valve (10) is operated by a thermostate (21) which allows more or less water to pass through the heat exchanger. The heat exchanger is fitted internally with a coil (7) which carries the water to be heated. An auxiliary pump (17) feeds the water to the coil, by passing the radiators.

Title: Multi-jet gas burner for industrial biscuit ovens etc. - has jets with pilot flames protected in U-section channel
IPC: F23D14/26
Filed: 1974-11-27
Abstract: A gas burner for baking ovens etc. comprises a number of independently burning jets spaced along a supporting pipe which supplies them with gas, each jet having main flame orifice and a smaller, pilot flame orifice. The jets all protect from the pipe to pass through the base of a common, U-section channel of which the sides extent beyond the outer tips of hte jets to shelter the pilot flames. The channel can be formed integral with the pipe or can be removably attached to the pipe by jet shoulders clamping the base of the channel as jets are screwed into the pipe; in the latter case, pref. some of the jets are not fully screwed in, to leave a clearance between shoulder and channel base. The burner can be made in strip or ring form. Used in multi-jet gas burner partic. suitable for industrial biscuit-making ovens. The channel prevents accidental extinguishing of the pilot flames; ignition of main flames spreads instantly to all jets along the channel.

Title: Opening and closure device for washing machine drums - has pressed projection, instead of shoulder on side of cylinder
IPC: D06F37/10
Filed: 1975-02-28
Abstract: The machine is filled from the top and the drum is reached through a window on the side of the cylinder (drum), the window being moved by means of a sliding door. There is a pressed part, projection outwards, on the side of the cylinder. The projection replaced the shoulder or detachable part, which was fixed to the outside of the drum by rivets in the prior art. The projection possesses a rectangular base and a section in the form of a rectangular triangle, the small side of the right angle, occupying an almost radial position with reference to the drum. It thus fixes limits to the parth covered by the sliding-door, the back edge of which is damped.

Title: Cylindrical ducting made from semicylindrical guttering - is joined by longitudinal clips to form complete cylinder
IPC: F16L43/00
Filed: 1975-03-12
Abstract: Cylindrical ducting for a pneumatic conveyor, ventilating system etc., is in two halves each formed separately and with a flanged longitudinal edge (1a, 2a). The ducting may be made of steel or aluminium. In assembly the two halves are brought together, and a longitudinal clip (3a, 3b) is applied to each joint. The seam is then closed by applying pressure to the joints. Elbows and tee pieces may be made in the same way and the ducts are joined end to end after fabrication with male and female sockets. This method allows the storing of incomplete components in a smaller space. The joints do not require soldering.

Title: Silicate-base aid for paper mfr. - contg. alkali silicate and alkali fluorosilicate, opt. with other alkali salts and polyhydroxy cpds.
IPC: D21H17/24
Filed: 1975-05-22
Abstract: Silicate-base aid for paper mfr. is produced by mixing alkali silicates with alkali fluorosilicates, opt. with alkali carbonates, bicarbonates, fluorides or other salts with strongly polar anions and/or organic polyhydroxy cpds. Beneficial effects of alkali silicates on pulp prepn.

Title: Shot-blasting machine having vibrating openwork tunnel - with walls which approximate to the shape of workpieces to be treated
IPC: B24C3/08
Filed: 1976-02-27
Abstract: A shot-blasting machine includes a chamber housing an openwork carrier for holding a workpiece. The carrier is in the form of a tunnel having perforated walls and is adapted to be vibrated. Impellers are provided for throwing shot against the workpiece. The walls of the tunnel approximate the shape of the workpiece to be treated, or alternatively are shaped to give the required orientation of the workpiece for the required treatment and finish. The machine is used for removal of sand from foundry castings. Sand can be removed from intricate passages and cores in the castings. The action of the high velocity stream fo shot and the vibratory movement of the tunnel breaks up and shakes out the core sand. The tunnel protrudes at either end from the chamber to permit feeding and removal of the workpieces with safety.

Title: Ticket control mechanism for ticket vending machine - has anti-return mechanism which prevents slipping of ticket output slide
Inventor: FAUJOUR PAUL
IPC: G07B3/04
Filed: 1976-05-06
Abstract: The ticket machine housing (1) has an antireturn mechanism which prevents a ticket output slide (5) from slipping. The mechanism has a pin (8) mounted on the housing (1) so that it can be displaced in a direction transversal to the direction of the slide (5). The pin (8) is pulled towards the slide (5) by a spring. The pin (8) is lodged in a throat (9) formed in the slide (5). the throat (9) forms a closed path. One end (10a) of the throat (9) is situated at a distance (D1) from the front end (9a) of the throat (9). This distance (D1) is greater than the distance (D2) separating the shoulder (6) of the rear edge (7) of the upper ticket. This is when the ticket is in the rest position between the slide (5) and the housing (1). The end (10a) of the throat (9) increases the depth of the throat with respect to its front end (9a). The throat (9) has a ramp (10b) which progressively reduces its depth after the end (10a) to its depth at its front end (9b).
