Patent FR-2288257-A1 (FR)
Title: Variable width vee-pulley - has spring steel washers holding pulley cheeks against belt
IPC: F16H55/56
Filed: 1974-10-15
Abstract: The variable diameter pulley has two pulley cheeks which can slide axially along the carrier hub (1). Between the outer end of each pulley and the end of the hub are fixed a pair of concentric sprung steel washers (3) that keep the cheeks biassed axially upwards. This ensures that whatever the position of the belt (4) between the cheeks, there will be sufficient cheek/belt/cheek compression to permit drive. The sprung steel washers are riveted together at their outer peripheries, and one pulley cheek is slidable over a sleeve of the other cheek which is mounted on a shaft.

Title: Mechanically operated drum brake - has wedge forcing balls apart in brake segment mounting plate to force segments apart
Inventor: MERY JEAN-CLAUDE
IPC: F16D51/24
Filed: 1974-11-13
Abstract: A drum brake consisting of a support plate on which are mounted two slidable segments which can engage by friction against a brake drum. The segments are moved by a wedge (52) between two adjacent ends of the two segments. A support piece is placed between the other ends of the segments. The wedge is moved parallel to the drum axis and has concave guide faces (60, 62) which engage two balls (54, 56) also engaging the adjacent ends of the brake segments. Movement of the wedge moves the balls transversely of the drum axis to actuate the brake by moving the segments. The balls are guided by a groove (58) in an anchor block which holds the ends of the brake segments.

Patent FR-2284946-A1 (FR)
Inventor: DUNN JAMES GRANT
IPC: G10L19/00
Filed: 1975-09-10
Abstract: This invention relates to a digital vocoder where speech is translated to a digital version thereof. An adaptive filter in the form of an N stage Itakura type cascade derives from the speech a prediction residual and N spectral parameter in the form of weighting coefficients of the filter. The pitch period, derived from the prediction residual, the voiced/unvoiced decision derived from the first of the weighting coefficients and the peak amplitude of a pitch pulse, and a digital signal representing filter gain, derived from the last of the weighting coefficients are multiplexed with each other and the N spectral parameters for transmission to a receiver. The receiver employs an excitation generator responsive to the pitch period, the gain signal and the voiced/unvoiced decision to produce an excitation signal to excite an N/2 cascade connected stage receive filter. Each stage of the receive filter operates on a time shared basis on an adjacent pair of the N spectral parameters. The receive adaptive filter operation is the inverse of the transmit adaptive filter so that after digital to analog conversion the original speech is substantially reproduced.

Title: Underwater rotating turret video camera - uses single cable to support camera and to provide electrical and video connections for control above water
IPC: H04N7/18
Filed: 1975-11-04
Abstract: The underwater video camera is supported by a single cable which is also used for electrical and video connections. The camera has interchangeable objectives and is mounted on a rail which permits adjustment of the focal distance to a reflecting mirror. The camera uses a turret which pivots by means of motorised reducing gear mechanism fitted with a friction wheel which drives a band on the turret through 360 deg. rotation. The turret supports another motorised reducing gear which is fitted with a cam which actuates a crank arm. The crank arm drives a second cam attached to a pivot fixed to the mirror which permits it to rotate through 180 deg. Thus the direct field of the camera is reflected by the mirror to achieve the field of reflection. When the field to explore is directly below, it is sufficient to position the mirror in the vertical positions. The thickness of the mirror being so close to the objective that it is not visible.

Title: Horizontal axis aerating rotor for waste water treatment - uses polygonal rotor modules with angled beater blades
IPC: B01F3/04
Filed: 1976-03-18
Abstract: The rotor comprises a power-driven horizontal, rotary shaft fitted with removable, coaxial modules made up of end plates in the form of regular polygons, with flat stringer plates joining the corresponding sides of the two end plates. Beater blades are fitted on the outsides of the stringer plates to agitate the waste water as the rotor rotates. The beater blades lie in planes set at a selected angle to the axis of the shaft. Each side of the hexagonal side plates is pref. bent in towards the centre of the module and the beater blades are removably attached to the stringer plates. The angle at which beater blades are set is pref. the same for all blades on a module. On successive modules the angle changes in steps of 15 degrees, i.e. the first module has blades at 15 degrees, its neighbour 30 degrees, the next 45 degrees etc., 60 degrees pref between the max. Alternatively, all blades on all modules of a single rotor can be set at the same angle. Used to oxygenate waste water to promote biological purificn. It is easier to fit beater blades on to the flat stringer plates of a rotor in the form of a regular polygon than on to the curved surface of a cylindrical rotor. Blade angles can be different across the width of a treatment channel to suit varying requirements.

Title: Pressure sealed pneumatic or hydraulic cylinder - has pressed metal end cap attached to thin walled tube by brazing or spring rings
IPC: F16J10/02
Filed: 1976-09-03
Abstract: The pneumatic or hydraulic cylinder is made from a thin walled tube (16) which is brazed or soldered to a thin walled end cap (15). The end cap (15) is pressed or spun from sheet metal and is thus much lighter and cheaper than a similar cap machined from a solid block. As an alternative to brazing the tube may be secured by identing it with a semi-circular groove (19) for a spring ring (20) which also fits in a corresponding groove (18) in the end cap (15). A second groove (17) is formed in the end cap (15) for an O-ring (21) which provides an effective seal against the internal pressure.

Abstract: 1525060 Electronic watches DAINI SEIKOSHA KK 22 Dec 1976 [29 Dec 1975] 53535/76 Heading G3T [Also in Division H1] An electrical switch comprises a rotatable cam 8 having a projection 9' engageable with a contact spring 13 and a projection 9 engageable with a cam spring 10, the arrangement being such that when the cam 8 is rotated by drive means 4 the cam spring 10 is flexed by the cam projection 9 and then moves under its own resilience to apply a rotational force to the cam 8 causing the other projection 9' to move the contact spring 13 into contact with a fixed contact 18, 19. The switch is mounted in an electronic watch having an axially movable and rotatable stem 4 mounting a clutch wheel 1 and a freely rotatable pinion 2 which meshes with a transmission wheel 5 rotatably mounted together with the cam 8 on a pin 6. A pin and slot 16, 17 lost motion mechanism is provided between the transmission wheel 5 and cam 8. When the stem 4 is axially moved to drivingly connect it to the clutch wheel 1, the clutch wheel 1 meshes with the pinion 2 whereby rotation of the stem 4 in one direction causes clockwise rotation of the cam 8 after the lost motion 16, 17 has been taken up. The cam projection 9 is moved past a projection 10a of the spring 10 to cause the latter to flex and then impart a rotational force to the cam 8 which causes the other cam projection 9 to move the contact spring 13 relative to a contact 18. If the cam 8 is rotated anti-clockwise by the stem 4, the cam projection 9' engages the cam spring 10 and the cam projection 9 moves the contact spring 13 into engagement with another fixed contact 19. The contacts 18, 19 are connected to circuits which control time correction and resetting.
