Patent FR-2231037-A1 (FR)
IPC: B65H21/00
Filed: 1974-05-24
Abstract: 1456163 Ultrasonic seaming METRO KALVAR CORP 23 May 1974 [23 May 1973] 23168/74 Heading B5K [Also in Divisions G2-G3] A photographic film splicer comprises an ultrasonic transducer horn 90 having a stationary narrow elongated tip portion 130 and an anvil in the form of a rotatably mounted circular member 114 which rolls over the said tip portion and defines with it a narrow compression zone in which the splicing is effected. As shown, the film strips to be spliced are positioned in respective film block subassemblies 40, 41 (Fig. 1), the left hand subassembly 41 being shown in more detail in Fig. 3. It comprises a block member 46 and a cover member 55, both pivotally mounted on a hinge pin 45 carried by a hinge block 42. The hinge pin passes through bored shoulders 47, 48 of block 46 and a bored shoulder 56 of cover 55. Block 46 has a cut-out slot 53 in which one film strip is positioned, after which the cover 55 is closed and locked shut to clamp the film strip in position. The film end is now trimmed by a cutter assembly 12, which comprises a fixed member 80 and a movable cutter blade 81, which pivots downwards with a guillotine action. The whole subassembly 41 is then pivoted clockwise (Fig. 1) into the splicing position, and the other film strip end in subassembly 40 is similarly treated. A cam 70 is attached to the shoulder 48 of block 46, and another cam 72 is attached to hinge block 42. Thus as subassembly block 41 pivots clockwise the co-action of one cam against the other causes the block to move to the right. Similarly when block 40 is pivoted, it is caused to move to the left. Consequently the two trimmed film ends are moved towards each other, and so overlap slightly. In this position, the overlapping film ends now lie on the narrow elongated tip portion 130 of the fixed part 90 of the horn. The movable anvil subassembly 91, seen in Fig. 1 and in more detail in Fig. 4, comprises an L-shaped block 92 which is guided for sliding movement by rods 93, 94, and is driven by a rack 121 which engages with a motor-driven pinion (123, Fig. 2, not shown). Within the overhanging portion 109 of block 92 is positioned an anvil arm 108, pivoted on a dowel pin 111 which passes through an aperture 113 in the anvil arm. The rolling anvil itself is a wheel 114 carried at one end of the arm. When the film ends are located in position and ready for welding, the assembly 92 is moved forward, so that the film ends are compressed between the rolling anvil 114 and the narrow tip 130. On the return movement of the anvil the ultrasonic generator is energized, and the actual welding operation takes place to produce the splice. The whole sequence is controlled generally by the circuit of Fig. 5 (not shown), and provision is made for modifying the apparatus for accommodating film strips of different widths.

Title: Displacement valve with tapering shut off - is secured against turning and fits in housing with sealing cover
IPC: F16K3/30
Filed: 1974-09-26
Abstract: The advantage of the design is that the sealing does not deform when the valve is set for a long period in the closed position. This often happens with other designs under the influence of temperature changes. The openings for the valve are in the housing wall and these form part of the flow pipe. The sealing cover has a series of external grooves and in the seating it has a greater surface area than the openings. In the closed position the edge of each ridge is at a clearance from the rim of the opening in the wall of the housing recess. The closing element for the valve and the recess have a truncated cone shape.

Title: Enclosed fireplace for burning logs - has controlled airflow and glass front preventing sparks but passing heat
IPC: F24B1/18
Filed: 1974-10-25
Abstract: The fireplace for burning logs is both a means of heat supply and also decorative, but does not allow the smoke to escape into the room. It is easy to light and, once lit, remains burning steadily without the need for constant supervision. A sheet of heat resistant glass which can be fixed or movable completely covers the front of the fireplace, but allows the warming rays to pass through into the room. Air enters at one point only and the flow can be readily adjusted. This design is also fire-preventive because sparks are unable to fly out of the grate into the room.

Title: Closure device with spindle operated valve plate - has toothed coupling pieces and seat for gas circuit
Inventor: BUISSON ANDRE
IPC: F16K29/00
Filed: 1974-11-08
Abstract: Cut-off device in which a valve plate moves forward under the operation of a valve spindle. At the commencement of the closure movement, the valve plate (4) is picked up by the movement of coupling pieces (6, 7). As soon as the valve plate (4) comes in contact with the valve seat (3) the valve spindle (13) moves forward, in order that the valve plate (4) be engaged in the movement of the coupling pieces (6, 7). A spring (5) allows the valve plate (4) to rotate without the contact force exceeding a limit value which is experimentally determined, dependent upon the relative hardness of the fixed components of the device and the material comprising the seal parts. At the end of the closure period, the two coupling pieces (6, 7) separate and the rotary movement ceases.
Patent FR-2290147-A1 (FR)
Title: Paracasein and whey separation system - combines suction decanting with tipping over filter grid in flow line
IPC: B01D35/28
Filed: 1974-11-08
Abstract: Paracasein is sepd. from whey in chees manufacture by removing most of the whey from the tank with coagulated milk by suction, followed by tipping the tank contents over an inclined chute and a filter grid which passes only the residual whey. The paracasein which flows over the grid is sepd. into smaller containers. This removes most of the whey without disturbing the paracasein and improves efficiency of the subsequent filtration on a grid. All stages are fully mechanised, including the washing of the empty tanks.

Title: Printing process rendering falsification obvious - uses inks having different solvents so that one disappears
Inventor: DENAY ANDRE
IPC: G07D7/00
Filed: 1975-03-17
Abstract: The process is for the prevention of falsification of a document by rendering such falsification obvious. The base of the document is printed with several inks, each having a different solvent, so that in the event of falsification one at least of the base impressions disappears. The inks used can each contain pigments reacting in a different manner, so that falsification causes one impression at least to change colour. Alternatively, the inks can be be of different colours, while the different impressions partly overlap. Thus falsification causes a colour alteration.

Title: Flywheel magnetic repulsion motor - inserts magnetic screen between permanent magnets in repulsion to annul dead point and give drive
IPC: H02K53/00
Filed: 1975-12-15
Abstract: The magnetic motor uses permanent magnets (4.3, 6.7) which ensures the continuous rotation of a flywheel (5) by successive magnetic repulsions. The motor uses in combination a fixed permanent magnet (4, 3) and a moving permanent magnet (6, 7) which is mounted on the flywheel (5). It also uses an iron magnetic screen (10) which is interposed between the permanent magnets when the approach closest to each other. When the two magnets approach each other the magnetic fields produce lines of force which tend to neutralise each other and produce a braking effect. The magnetic screen is inserted to create a neutral line which annuls the braking effect and ensures passage through the dead point.
