Patent FR-2085767-A1 (FR)
Title: Tooth paste contng fluorine cpds
IPC: A61K8/81
Filed: 1971-03-31
Abstract: Toothpaste for preventing dental caries, loosening of the teeth and the like contains fillers and/or abrasives and at least one F cpd. and optionally water-absorbent, wetting and thickening agents, antibacterials and flavours. The F-compds. have formula XMnFy where X = alkali (ne earth) metal, Mn is bivalent and y = z + 2, being the valency of X. The fillers or abrasives consist of small particles plastics e.g. polymethylmethacrylate, or of Ca3(PO4)2 or SiO2 coated with such plastics. A reduced quantity of F-compd. can protect the enamel without endangering the gums as only little is absorbed on the fillers or abrasives.

Title: System to control air-fuel mixture - on existing motors without replacement of existing parts
IPC: F02D41/00
Filed: 1973-06-27
Abstract: To correct the air-fuel mixture of combustion engines the system has a sensor in the exhaust which analyses the gasses and transmits at frequent internvals impulses which vary in time recording to analysis. These impulses are received by an electro-valve which opens and closes if impulses are outside certain preset limits. This electro-valve modulates the vacuum in the carburettor. This vacuum forms a function for the action of a membrane which can activate an auxiliary air valve injector to restore right amount of air according to analysis of exhaust gasses.

Patent FR-2279297-A1 (FR)
Title: Line and frame control for image tubes - has three pilot pulse series controlling two monostables and gate
Inventor: COLLIN JACQUES
IPC: H04N3/24
Filed: 1974-06-12
Abstract: The line, frame and flyback control for image tubes provides remote control and increases the general system flexibility. A circuit provides, from a possibly remote position, a pilot signal of three pulse series at a fixed frequency but of different durations. A circuit associated with the image tube is triggered by the first and shortest duration pulses and provides, as a monostable oscillator, an output pulse longer in duration than its trigger but shorter than that of the second and third pulse series, this controlling the line sweep. A second monostable circuit receives the second and third pulse series, providing frame and flyback control, a gate combining the monostable signals to control flyback extinction.

Title: Electric razor with long and short hair cutting heads - has linkage to motor via stud and slot
IPC: B26B19/10
Filed: 1974-10-16
Abstract: The electric razor has separate long and short hair cutting heads, the latter (16) locating longidutinally adjacent to the former (3). A reciprocating cutter (9) beneath a static foil (3) is driven via motorized (7) stud (6) engaging cutter support body (8) a lower lateral extension of this body (8) linking with the long hair cutter. This latter is a reciprocating toothed blade (20) locating beneath a static cutter (15), and the movement of this head into an active station effects linkage with the motor and reciprocation of cutter (20). The linkage is a laterally projecting stud (11) engaging a slotted (28, 29) extension of cutter (20), and a 'T' shaped slot requires a sliding elevation of head (16) to locate stud (11) in the stem (29) of the 'T' slot and effect cutter motivation.

Title: Plug in circuit connection element - has circuit fitting in sliding connector body movable between two positions
Inventor: THENON CHRISTIAN
IPC: H01R13/74
Filed: 1974-11-15
Abstract: The element (1) has a circuit which can be plugged into a connector body (3) carried by a fixed support (6). The connector body (3) slides in a case (4) fixed to the fixed support (6), and two stops (7, 8) determine, with respect to the case, two extreme positions of the body and the circuit connected to it. There is a first position in which the pluggable circuit is relatively close to the case and a second position in which the circuit is farther away from the case. The frictional force required to connect or disconnect the pluggable circuit to or from the body is greater than the force necessary to displace the body in the case from the first to second position or vice versa.
Patent FR-2296293-A1 (FR)
Title: Commutator machine for high output - employs mechanical and semiconductor commutation with built-in diodes
IPC: H02K13/14
Filed: 1974-12-26
Abstract: The output of commutator machines is enhanced by spark suppression at the brushes through means involving the addition of diodes in the brush-commutator-winding path. The adverse effect on the size of commutator brought about by this construction may be overcome by building the diodes into the commutator segments. Each segment comprises a conductor plate (1) to which the windings (2) are joined. Contact plates (3, 4) on each side are insulated from the conductor plate using typically a sheet material (5). Recesses are cut into the contact plates to take the diode pellets (7) of appropriate polarity, which made connection to the contact plate. The contact plate surfaces are arranged to come in line axially at the commutator surface to give a positive and a negative brush track.

Title: Colour projection memory tube - uses Fabry-Perot filters with deforming mirror to deflect light beam
Inventor: DALTON JOHN J
IPC: H01J29/12
Filed: 1974-12-31
Abstract: The target of the information projection tube is made from a dielectric surface which provides a deforming mirror (36) and a transparent series of Fabry-Perot filters (22). A writing electron-gun (16) forms a charge on the target which deforms the mirror surface. A light source (60) is directed through an optical system into the target and, due to the interference action of the filters, creates a coloured pattern on an optical screen (74). An erase-gun (28) is also provided. The target can be made of alternate layers of zinc sulphide and cryolite with a mirror of deposited silver. This provides colour projection of the electron-gun information instead of the black and white display in previous tubes using Schlieren optics.

Title: Non rotating projectile safety system - includes multiple cam mechanism to prevent striker pin being operated by clockwork drive
IPC: F42C9/04
Filed: 1975-02-27
Abstract: The non rotating explosive device such as a rocket or mortar has a clockwork drive to operate the striker pin to explode the percussion charge. A rotating member sets the time of operation, a set of gears and an escapement also being included. A set of safety devices prevent premature operation, and includes two actuator cams and a sloping member (8c) to control these devices and forming part of a rotating assembly (8). These cams include rectangular cut-outs on the edge of a dise which allow a striker pin (20) to be forced into the percussion charge after a given rotation. This is operated by a release arm (14) mounted on a spindle parallel to the striker pin. The rotating assembly includes a retaining collar on one of the cams to block the striker pin in a safe position for transport and storage.

Title: Cover for electrical switch base - is removed by operating two levers from its front face and has catches operated by screwdriver
IPC: H05K5/03
Filed: 1975-04-14
Abstract: The cover (12) is used to protect the base parts of electrical switches which may be arranged to be exposed by a window cut in the cover. The cover is held in place by a deformable plastics catch engaging with the switch box base. Release of the cover is achieved from the front rather than from the sides so allowing such boxes to be mounted closely side by side. The cover is made entirely of plastics and its side faces are provided with a location strut serving to ensure correct positioning. Two openings on either side of the front face open onto mouldings in which are pivoted levers having catches engaging with the base plate. These are released by downward pressure of a screwdriver or similar blade through the front opening.

Title: Measuring variations in contractive force of heart - using devices to monitor A and B phases of heart heat and measure time lags between them
IPC: A61B5/0215
Filed: 1975-08-06
Abstract: A device to measure variations in the contractive force of human or animal hearts has an instrument to analyse the specific phase A of the heartbeat. Another instrument analyses the specific phase B of the b lood impulse in a body member which is not the heart.
