Patent FR-2299606-A1 (FR)
Title: Temp. distribution in cold cabinet with deep-freeze compartment - becomes more uniform when cooling surfaces are placed symmetrically
IPC: F25B39/02
Filed: 1975-02-03
Abstract: The deep-freeze compartment is placed centrally and refrigerated from above and below (4, 5); evaporator surfaces (6) alongside it on both sides cool the main cabinet evenly. Heat-insulating material surrounds, the deep-freeze compartment, outside its own cooling surfaces (4, 5) but inside the surfaces (6) that cool the main cabinet, an arrangement allows the cold cabinet to be de-frosted without disturbing the deep-freeze. Spaced slots in the side walls accommodate a number of partitions in an L-shaped configuration, and to which the insulating material is fixed.

Title: Fruit or vegetable packaging - using mobile hopper receiving loads and discharging into moving bins
IPC: B65B39/14
Filed: 1975-02-28
Abstract: Fruit or vegetables are packaged by supplying them to a fixed load supply hopper which forms a predetermined load which is then discharged to a mobile hopper. The mobile hopper moves along rails parallel with and above the path of bins carried by an endless conveyor, the bins discharging into package forming assemblies. The mobile hopper moves between end stops, being returned to its original upstream position by a spring, but being moved by a bin to discharge into the bin. The mobile hopper has a lower discharge door controlled by stops on the bin and by fixed stops.

Title: Optical recording disc mfr. - uses vacuum deposition of metallised layer onto thin thermoplastics sheet
Inventor: PUECH CLAUDE
IPC: G11B7/26
Filed: 1975-04-02
Abstract: The optical recording disc, with a reflective optical structure, is made by pressing a thermoplastics support, to obtain an impression with alternate depressions and crests, representing an angularly modulated waveform. As the thin thermoplastics sheet (1), used as the disc support, is unwound from the roll, it is provided with a metallised layer (2) by vacuum deposition. The thickness of the thermoplastics sheet (1) provided with the metalised layer (2) is less than that of the required support, with a further layer (3) of the same thermoplastics material as the sheet (1) being applied to the latter, to obtain the required thickness of the support, on the opposite face to the metallised film (2).

Title: Correction for transcription faults on pressed video disc - employs optical detection system to provide signals with rectangular transitions
Inventor: LACOTTE JEAN-PIERRE
IPC: G11B7/13
Filed: 1976-01-16
Abstract: Signals recorded on a video disc are in the form of troughs and peaks which are susceptible to transcription faults during the pressing process. This is resolved by an optical signal detector system which provides signals with rectangular transitions for demodulation. A laser source (1) output is directed by a lens (2) onto a reflecting blade (3) and then through a focalising lens (4) onto the track on a disc (5). Light reflected from the disc is detected by photodetectors (6, 7) mounted symmetrically w.r.t. the optical axis on an adjustable carriage (8). Photodetector outputs are amplified and balanced (11, 12) and applied to an adding or differential amplifier (13) followed by a demodulator (14).

Patent FR-2335195-A1 (FR)
IPC: A61C5/06
Filed: 1976-12-16
Abstract: The device (1) is used for filling magazines (15) with plastic materials, for example with amalgam, for the filling of dental cavities. It consists essentially of a base element (2) which has a funnel (9) to be charged with amalgam and a hollow space (10) whose inner cross-section is at most equal to the inner cross-section (15') of the magazine (15) to be filled. Guided in the hollow space (10) with precise fitting is a thrust shaft (3), which has to be activated via the slide (4). In this way, the filling material arriving from the stopper (8) to the position (14) where the funnel (9) enters into the hollow space (10) is pushed into the inner space (15') of the magazine (15) arranged flush with this hollow space (10), and the whole magazine (15) is thus filled by multiple activation of the slide (4). With the aid of a such a device, it is possible to ensure a rapid and complete filling of detachable magazines of any constant inner cross-section with amalgam or any other appropriate filling material produced beforehand, for example in a conventional amalgam oscillator. The device is of a simple design, it is easy to operate and it has a high temperature resistance on sterilization.

Title: Self draining mounting for road vehicle window - has moulding with outward fall and housing vertical perforated flange behind perforated seal
IPC: B60J10/02
Filed: 1977-01-25
Abstract: The peripheral moulding (3) may be used to mount a window (20) of an automobile and incorporates drainage outlets (12) for internal condensation. The moulding provides opposed channels (4, 6) which house the edge (5) of the opening and the vertical flange (7) of a window frame (2). The top face of the moulding is shaped (17, 11) to fall towards the exterior, to seal (15) against the underside (18) of the frame (2), and to permit condensation to flow out through the perforated (12) flange of the frame (2). The frame (2) is of a 'T' section with a short vertical upward return on the internal end of the bar, and the flange (7) or vertical leg is partially housed in the resp. channel (6). The flange projecting above the channel incorporates the drainage perforations and forms a gap between the top of the moulding and the underside of the frame.

Title: Power operated lathe chuck - with linear motion of piston changed to rotation by bush with helical splines
IPC: B23B31/167
Filed: 1977-07-11
Abstract: The jaws (4) of the power operated chuck (1) are keyd to the segments (3) which slide in radial grooves (6) in the chuck body (2). The segments (3) are provided with teeth (13) forming spiral grooves. These teeth (13) mesh with teeth projecting from the blocks (11) which are fitted in the bore (12) of the body (2).

Title: Machine forming flange on rim metal manhole ring - has turntable to rotate ring, and pivoting arm with opposed movable rollers
IPC: B21D19/04
Filed: 1977-11-14
Abstract: A diametrically converging or diverging pair of rollers (10, 12) is used to form a square edge flange on a metal manhole ring (15), being incorporated on a machine supporting the rotating the ring. A turntable with an annular matrix (14) supports the ring, the rollers being mounted on slides (9, 11) on a pivotable and lockable arm (4). The arm pivots to the vertical to allow the ring to be positioned, and is returned to the horizontal to locate the rollers on the edge of the ring. Once the arm is locked (7), the rollers are progressively advanced in opposite directions on a ring diameter as the ring is rotated. The rollers (10, 12) are respectively of a formative and counter-thrust type, and their slides are displaced by a motor (13) driven screw with reversely threaded drive shafts.
