Patent FR-2278988-A1 (FR)
Title: Wheel or cable drum band brake - has spring steel cores attached to spreader plates at ends
IPC: F16D65/04
Filed: 1973-04-24
Abstract: The band brake is for vehicle wheels or cable drums. Spring steel support cores carry the asbestos based brake linings which may almost completely surround the drum, but if the linings are thick or inflexible, they may be split into sections. At the ends of the linings the steel cores are carried to spreader plates which are connected to the hydraulic actuating mechanism. In this region, the cores cross over easily, due to their spacing. The springiness of the cores ensures that the linings separate from the drums when the braking force is not applied.

Title: Liquid operated impact tool - has liquid operated piston to compress gas which provides impact
IPC: F01L25/06
Filed: 1973-11-21
Abstract: The tool has a main piston fitted into a main cylinder, the upper chamber of the main cylinder being filled with gas of predetermined pressure. A liquid chamber for containing liquid for pressing the main piston upward by liquid pressure is provided between the lower half of the main piston and the main cylinder. On the lower end of the main cylinder is fitted a tool, such as a chisel and the like, which is struck by the main piston when the main piston is driven down by the gas compressed in the upper part of the main cylinder by the raising of the main piston. Thus the exhaust noise of a conventional pneumatic device is avoided.

Title: Protection cct. for TV receiver - receiver has HV stage with resistor at base end
IPC: H04N3/20
Filed: 1974-09-09
Abstract: A circuit for protection of a television receiver with a high voltage cascade circuit having a resistor at the base point. The foremost protection offered is for the cathode ray tube should faults develop in the high voltage circuit. The information for the operation of the beam current limiter and a mains protection circuit is created from a decrease in the d.c. potential at the resistor, the d.c. potential being proportional to the beam current. A diode is connected in parallel to the resistor, which arrangement offers greater protection of the most important parts at less cost. The operational levels are subject to very fine control since neither protection circuit is dependent upon the form of the negative line impulse.

The platforms are positioned by two jacks pivotally mounted on the floor of the garage with the upper ends of the jacks pivotally mounted on two lever arms. One end of each arm is pivotally connected to a draw bar secured to the lower platform and the other end has a roller runner on a guide under the upper platform, these arms forming lost motion devices.
Patent FR-2293384-A1 (FR)
Title: Telescopic truck loading arm - has integral conveyor belt turn over piston to assist stacking of sacks
IPC: B60P1/36
Filed: 1974-12-03
Abstract: A telescopic loader arm has an integral conveyor belt to load sacks onto the platform of a truck. At the free loader arm end, a conveyor extension is hinged to the arm so that it can swivel in a horizontal and vertical plane. At the free end of extension, a hydraulic piston is attached which turns the sacks that come of the conveyor in a longitudinal direction. In this way they fall on top of the stack which is being formed. Since the loader arm can reach any point of the truck platform from the rear end of the truck, it can load a lorry without removing its covers.

Title: Sintered glass-ceramic bodies having low dielectric constant - contg. polycrystalline, refractory, ceramic phase and glass phase
IPC: C04B35/634
Filed: 1975-01-10
Abstract: Sintered glass-ceramic bodies having a low dielectric constant contain a poly-crystalline, refractory, ceramic phase and a glass phase (borosilicate or alumina-borosilicate) formed between the crystalline aggregates in an amt. of 25-65 wt % (pref. 35-50 wt %) w.r.t. the whole material. The ceramic phase is pref. alumina, spodumene, wollastonite, magnesium silicate and/or kyanite; it can be acidic, basic or neutral. The material is used for electric insulation, esp. for multilayer electronic packages. The dielectric constant is low (the ceramic phase 6-9; the glass phase 5.0; the dielectric constant of the material as a whole is 4.3-6.2) and so is the coefft. of thermal expansion (5 x 10-6 degrees C-1, esp. 3.3-4.5 x 10-6 degrees C-1). The sintering temp. is relatively low (825-929 degrees C); therefore, the material can be metallised with Ag, Cu or an, or their alloys with Pd or Pt. The material has high density (2.15-2.35 g/cm3) and is impermeable to liquids and gases. The bending strength is high (2100-4200 kg/cm2). The dielectric loss is low (0.05, pref. 0.001 at 1 kH2-200 MH2). The thermal conductivity is high.

Title: Isolation of hepatitis B sheath antigen - by affinity chromatography of serum on immobilised immunoglobulins
Inventor: MAUPAS PHILIPPE
IPC: C07K14/02
Filed: 1975-12-19
Abstract: Isolation of hepatitis B virus sheath antigen (HBs) is carried out by contacting an HBs-contg. serum (opt. after dilution or concn.) with at least one HBs-specific immunoglobulin coupled to a support, which is then washed to remove serum components other than the antigen. The antigen is then eluted and opt. subjected to further purification or concn., esp. to remove any residual serum proteins. The antigen can be used to prepare vaccines against hepatitis B (serum hepatitis). The process gives high-purity antigen without modifying its physicochemicals or immunological properties.

Title: Spring aided reciprocating compressed air motor - has toggle mechanism on valve to eliminate dead points at ends of stroke
Inventor: TERRILLON JEAN
IPC: F01L23/00
Filed: 1976-02-13
Abstract: The motor has a piston (2) which is pushed down by a spring (3) and up by compressed air. The air is controlled by a valve which has a spindle (14) on the same axis as the piston. The spindle has shoulders (16, 28) which open and close the valve ports. The spindle is joined by toggle springs (11) to a toggle carrier (7) which overlaps the valve and has a flange (8) above a shoulder (25). The piston has a carrier skirt (4) which pushes on the toggle carrier shoulder on the downstroke and grips the flange on the upstroke. This causes the toggles to reverse the valve before the piston reaches the end of its stroke and thus avoids dead points at the ends of the stroke.

Title: Textiles with industrial colour printing - using threads with different affinity for dyes
IPC: D06P5/00
Filed: 1976-06-17
Abstract: Conferring a particular appearance to industrial colour printing aplied to textile supports, e.g. woven or knitted fabrics, is carried out by mfg. the textile support os as to create differences in behaviour with respect to printing. This is performed by using threads which differ in their affinity for dyes, w.r.t. their nature and/or size and/or twist and/or colouring. The support pref. provides relief effects by its actual texture. The dye thus takes unevenly on the support, providing it with a hand-made appearance. The printing method may be e.g. silk screen printing, partic. Lyons printing, or thermo-printing i.e. by sublimation.
