Patent FR-2279915-A1 (FR)
Title: Buffer block for tilting window - is on edge of window in line with slider on stay bar and shaped for adequate compression
IPC: E05C17/24
Filed: 1975-07-25
Abstract: A tilting window with a swinging arm attached at one end by a pivot pin on the fixed frame, and with a slider at the other end which also acts as a pivot and which travels in a track along the edge of the window frame, has a buffer block mounted on the same edge, in line with a peg on the end of the slider, so that if the window is suddenly swung open completely, the peg strikes the buffer. This buffer is a strip of resilient material consisting of a set of rings interconnected by narrow necked portions, and is housed inside a C section cover, this combination permitting an adequate compression to take place.
Patent FR-2282976-A1 (FR)
Title: Dry shaver plate - has central portion of barriers between apertures thinner than at edges(NL-4.3.76)
IPC: B26B19/38
Filed: 1975-09-02
Abstract: The plate has apertures separated from each other by barriers, each comprising a central portion joining onto the edges, which stand proud of the plane of the sheet round the apertures. The central portions (7) are thinner than the edges (7), and they can be made thus by grinding. The design allows the plate to be flexible, while keeping the edges thick enough to wear down slowly as the cutter blade (6) works against them. In addition, grinding off part of the central portion of each barrier allows the hairs to be cut off shorter thus gives a closer shave.
Patent FR-2286797-A1 (FR)
Title: Treatment of effluent by aeration - with short shocks of high and/or low oxygen concentration to select the best micro organisms
IPC: C02F3/34
Filed: 1975-10-02
Abstract: Liq. contg. suspended or dissolved material subject to breakdown by microorganisms is treated by injecting a gas contg. oxygen. For some of the time at least part of the liq. has a low dissolved oxygen concn. (defined as the partial pressure) and/or at least part of the liq. has a high dissolved oxygen concen. so that the ratio of carbon dioxide to cellular material formed in the processed is increased. The times during which the high or low concns. are maintained is kept short enough for the influence on the microorganisms not to affect their working adversely. This is also ensured by maintaining the liq. for part of the time at inter. oxygen concns. Used for treating effluent (normally aqs) after solids have been removed. The process may be used as an aerator or as a digester. The changes in oxygen concn. select for the most desirable microorganisms.

(I) are useful for the treatment of protozoal diseases in humans and animals, e.g. Trichomonas vagnialis, Entamoeba histolytica, Trypanosoma cruzi, Tryp. brucci and Tryp. congolense infections.
Patent FR-2334024-A1 (FR)
Title: Tooth form for infinitely variable ratio gearboxes - has convex section shape to smooth speed changes and extend life
IPC: F16D3/18
Filed: 1975-12-03
Abstract: Modification of the tooth form in this design infinitely variable gearbox extends the life, increases smoothness of operation and reduces noise of the transmission. The speed change mechanism is of the type where a pile of discs (9) may slide axially on a shaft (10), rotation being prevented by teeth (13) registering in splines (11) on the shaft. The flanks of the teeth (8, 13) on the discs (9) and rings (2) are shaped so that in section they form an obtuse angle down the centre of the tooth face, convex outwards. Preferably the angle is of order 172 deg. and allows a rocking motion of the discs and rings relative to the shaft axes during speed changes. This additional freedom eases the axial sliding of the discs and rings on the splines. It is alos advantageous to chamfer (16) the top edges of the teeth and arrange for the top face to have a slight angle of order 4 deg to the axial direction.

A pair of blocks (11) on the side members has holes (12) to hold the tenons (13) on the lower picture rest (14), this having a front lip (15). The picture leans against a vertical strut (16), fixed between the side members. It is retained in position by an upper rest (17, 18) dropped over the strut.

At least one tube is provided inside the roll in a longitudinal cavity and is connected to a collector passing through one of the journals. The coolant is supplied and removed via the collector. The rolls are used in continuous casting plants as guide rolls for the removal of the continuously cast ingot. Delicate machining operations are no longer necessary. The longitudinal spaces can be obtd. by machining a completely forged part, esp. by boring. The roll may be heated instead of cooled.

Title: Miniature low power DC electric motor - has bearing support by acting as heat sink and having spring allowing thermal expansion
IPC: H02K5/167
Filed: 1977-01-12
Abstract: A miniature low power DC motor is esp. for use in vehicles and in general household powered appliances. The motor design provides constant centralisation of the rotor with respect to the pole pieces and minimises friction effects due to heating of the motor under load. The rotor shaft bearings (1) are held in place by a single 'S' shaped spring metal support (3) which takes up any off-centering that occurs. The centre section of the 'S'(s) is expanded to hold the bearing case which itself is cogged (10) to mate with the support. The support is held within the motor casing by a pin at each extremity of the 'S'.

Title: Measurement of shortest distance between two moving objects - in which one object carries Doppler radar station delivering data signals from FM carrier waves (SW 5.6.78)
IPC: G01S13/50
Filed: 1977-07-27
Abstract: In the measurement system, a first object carries a Doppler radar station delivering a signal which carries information on Doppler frequency shift obtained from the echoes from the second object moving relative to the first. A signal processing unit responds to the Doppler frequency shift superposed on the signal. It derives from it the shortest distance between the objects. In a typical arrangement, the course (H) is at an angle to the track (Vr), and a radar signal is transmited along a radius vector (R) to the target (T).

Title: Solar energy house heating system - has storage vessel for heat transfer by heat pump to house
IPC: F24D11/02
Filed: 1977-10-17
Abstract: The system heats a house, using water for calorie transfer. Solar energy is obtained by collectors and part at least of the energy collected is stored in a vessel by heat exchange. The vessel acts as a temp. Regulator. The stored energy is in turn transfered to the house via a heat pump, raising the temp. There can be a vessel of smaller capacity between the storage vessel and the heat pump, in which the water temp. entering the heat pump is lowered.
