Title: Holder for tubes on a filling machine - has sleeve with annular slots containing springs gripping a tube
IPC: B65B43/54
Filed: 1973-12-10
Abstract: A sleeve (10), made from plastic, is fitted into the locating hole in the rotary table of the machine. This sleeve has a cylindrical outer form with a seating flange and two other flanges forming two grooves (16, 17) to hold endless coil springs (19). Each groove communicates with slots (16.2, 17.2) to allow the springs to enter into the bore of the sleeve and grip the tube. This bore is cylindrical at the bottom (21) and changes to an ellipse (20.3) at the top. The sides (20.2) correspond to the outer surface of the tube whose upper end (T1) is folded and progressively flattened, and a lip and bevel (21.1) at the bottom hold the cap end (C, T11).

Patent FR-2276957-A1 (FR)
Title: Thermostatic valve for automobile heater - has variable area bypass around air heater radiator
IPC: G05D23/12
Filed: 1974-07-03
Abstract: The thermostatic by-pass valve is in the water circuit of the engine radiator (d) and the engine (c). Some of this water can pass through the heater radiator (h) or it can be by-passed through another pipe (m). The control is partly manual and partly thermostatic. Flow of water through the valve is controlled by eccentric parts (3) (4) (5) mounted in a common shaft (6). Water can thus flow to the heater or be cut off from it by a control fitted to the shaft (6). In combination with the position of one eccentric piece (5) this coned valve gives fine thermostatic control of the amount of water by-passing the heater.

Title: Grain drying tower of modular construction - gravity feeds grain through horizontal hot air flow in superimposed tower sections
IPC: F26B17/14
Filed: 1975-02-12
Abstract: Grain is dried by gravity feeding down through a series of superimposed compartments forming a drying toner with hot gas passing horizontally through the grain in each compartment, temp. and flow rate of the hot gas passing through each compartment. Both become progressively less from top to bottom of the tower, all compartments operating below atmos. pressure. Used for drying grain such as corn, wheat, maize and other cereals to about 15% moisture content soon after harvest. The compartments form modules from which dryers of widely different capacities can readily be made up with height variation. Standard height dryers can be ranged side-by-side to give extra capacity with area extension only.

Title: Purificn. of hydrogen fluoride-contg. hydrogen chloride - by distillation with water vapour
Inventor: KOHLER BERND
IPC: C01B7/01
Filed: 1975-06-05
Abstract: Purificn. of HF-contg. hydrogen chloride by distillation is improved by removing from the head of the distillation column a HF-HCl mixt. contg. 5-50 mole % of water vapour, and condensing the water in a cooler in the form of conc. hydrochloric acid, which is used for absorption of HF and then partly recycled to the column, the other part being discarded. The one-step removal of HF without using any auxiliary chemicals is more economic than the known processes. The condensation is carried out at -20 to +30 degrees C under a press. of 1-5 kg./cm2. The HF content of e.g., 0.7 mole % is reduced to 0.03 mole % HF in the purified HCl.

Title: Compressed:air massage appts. - with preselected electronic programme control of air delivery to arm and leg sleeve
IPC: A61H23/04
Filed: 1975-06-13
Abstract: The compressed-air massage equipment allows massage to be carried out by pneumatic pressure on parts of the limbs or body. This is done to a programme pre-selected electronically, chosen so as to reproduce manual massage. The air can be delivered into sleeves divided into separate compartments, fitting over the upper and lower limbs in the thoracic and abdominal regions, the thighs and the spinal column. The width of the compartments is no greater than that of an average hand. The user can select from a control desk the method of operation, so that all compartments of a sleeve are supplied simultaneously, or alternatively in succession to give a travelling wave effect.

Title: Thermally shrinkable plastics film with hot-melt adhesive coating - used to cover containers
IPC: B29C61/06
Filed: 1976-05-13
Abstract: A sleeve or covering of retractable material is made which can adhere perfectly, after thermoretraction, to a container with complex shape and/or with completely smooth appearance, e.g. without a rim or groove on which to hook the material. Before or after the covering is cut out from the retractable film, at least a part of the surface of the film which will become the internal surface of the covering receives a coating, soluble in organic solvents and of low viscosity, of the same order as that or printing inks, which is dried rapidly for a few seconds at 35-70 degrees C. The coating layer becomes adhesive by reactivation at 50-140 degrees C during the subsequent thermo retraction of the covering around the container, and then becomes a colourless toughened coating.

Title: FM demodulator for TV receiver - has delay line discriminator comprising multiplier and conventional ring modulator
Inventor: POMMIER DANIEL
IPC: H03D3/06
Filed: 1977-02-28
Abstract: The FM demodulator (100) for a television receiver, has a delay-line discriminator. The discriminator contains a multiplier--which is used to multiply the undelayed signal with the delayed signal, and there is a conventional ring modulator. The delay line discriminator consists of a section of coaxial cable. The signals applied to the modulator inputs have the same amplitude -- an amplitude chosen so that the ring modulator diodes act as switching diodes. If a limiter is included before the discriminator then it too contains a ring modulator of the same type as the discriminator.
