Patent FR-2304245-A1 (FR)
Title: Retaining mechanism to fix unit to U-rail - uses metal covered snap-on locking piece for easy mounting
IPC: H02B1/052
Filed: 1976-03-10
Abstract: The retaining mechanism, for fixing an electronic or electrical unit to a U-shaped support rail, consists of a spring-loaded plastic locking piece whose end is wedge shaped to slide over and locate under the outward overhanging lip of the C-shaped rail. To ensure that the unit can be clipped into place easily without resorting to tools, the wedge end of the plastic piece is covered with metal to provide an easy-slip surface that allows the edge of the lip to slide smoothly along it. The metal surfface is formed by a metal sheet angled over the wedge and held firmly by a slot. The vickers hardness of the metal sheet is at least 160.

Patent FR-2348066-A1 (FR)
Title: Solid rubber tyres incorporating laterally adjacent hollow tubes - with an elastic foam bridge to enhance the lateral radial stiffness ratio
IPC: B29D30/08
Filed: 1976-04-14
Abstract: Pneumatic tyres are constructed with >=2 toroidal rubber tubes of similar or differing bore diam. and similar hoop diam. are positioned in a mould which permits a foamed rubber to be injected into the interstices between the tubes. The composite tubes/foam structure is enclosed by windings of rubberised cord in radial helical turns. The wound core is enclosed in a toroidal rubber sheath, opt. with a layer of reinforcing bandage between the core and sheath under the sub-tread and/or wheel rim faces. The sheathed core is then overmoulded or laminated to tread and rim face profiles. The internal tubes can be pressurised via either independent inlet valves or linked air supply system. Used for mfr. of hollow 'solid' tyres, ie. tyres without reinforced sidewalsl or rims and hence of simpler, cheaper construction than conventional crossply or radial ply reinforced tyres. The elastic bridges enhance the tyre stiffness against lateral distortion relative to easy radial distortion or compression, to provide a better combination of rolling comfort and roadholding when subject to lateral stresses during cornering.

Title: Sludge collector and light liq. separator - from sewage with two tanks in single housing and cover
IPC: E03F5/16
Filed: 1976-04-22
Abstract: Plant, for the sepn. of settled material and light liqs. from waste water and sewage, comprises a sludge collector and a separator for the light liqs; they form a compact installation in a common housing, with a cover. The water to be purified arrives at the inlet; material which settles out is deposited in the collector whilst the liq. passes over the overflow and under the partition into the separator. Here the associated light materials, such as oil, petrol, fats, etc. float to the surface while the water passes under the partition to the outlet. when the sepd. materials pile up sufficiently to be evacuated, a pump is brought into action; the light liqs. are withdrawn through one pipe and the sludge by another pipe. The layer of floating material is first broken up by the prodn. of a powerful, horizontal jet by the injector, making use of recycled water. After the evacuation, the collector and the separator are washed by water. The sepd. materials do not need to be evacuated by hand but can be sucked out by a pump when necessary or at regular intervals; this can be followed by a complementary washing.

Title: Road surface paving system - using hexagonal slabs arranged in groups of three separated by break points
IPC: E01C5/06
Filed: 1976-07-30
Abstract: The panel comprises a number of concrete paving slabs for surfacing roads, carparks, etc. Specific break points are formed between individual slabs by means of a groove in the joint area so that while some of the slabs are joined together others can be removed at these points. The slabs can be hexagonal and arranged in rows in units of three, offset at 120 deg. Each unit of three slabs is permanently fixed together while break points separate each of the units. The grooves forming the breakpoints have different dimensions, depending on the load which has to be carried. The design of these surfacing panels enable an even road surface to be obtained.
Patent FR-2324400-A1 (FR)
Title: Cutting tool withdrawal device - has motor driven tool feed spindle gear connected to withdrawal mechanism with energy storing flywheel
IPC: B23Q1/68
Filed: 1976-09-20
Abstract: The cutting tool carrier and tool is driven by an electric motor via a gear and spindle. A toothed wheel is also connected to the pinion of the withdrawal device. During normal operation, when the spindle is driven by the motor, a shaft fitted with satellite wheels drives the flywheel in the same direction as a countershaft. When current supply on the motor fails, switch gear contained in the housing operates a magnetic brake which attracts an external wheel. The rotation of the flywheel then produces an opposite rotation of the countershaft via a wheel and satellites, resulting in withdrawal of the tool.

Title: Open-crutch tights with separate legs joined at waist - combining option of replacing individual legs with greater hygiene
IPC: A41B11/14
Filed: 1976-10-15
Abstract: Open-crutch tights comprise two separate legs portions each joined to a body portion comprising a waistband which encloses a given length of elastic joining the two edges of the garment at waist level. The leg portions end just below the crutch. The garment is pref. made by circular knitting, with a split forming the two above edges formed in the knitting tube. The edges may be finished to prevent the stitches from coming undone, in order to create a finished edge extending as far as a point below the crutch. The body portion may have different properties of elasticity to those of the leg portions. The elastic in the waistband may be formed by a continuous length fixed at its ends to the edges of the garment, or it may comprise two separate parts fixed to the edges of the garment, with a releasable fastener between them.

Title: Chloroprene copolymers with reduced crystallisation speed - using dichloro-butadiene and chloro-butadiene comonomers
IPC: C08F2/24
Filed: 1976-12-03
Abstract: The polymers pref. comprises 69.3-98.8 (80.1-96.6) wt. % chloroprene (I), 20.1-1, (13.4-2.9) wt. % 2,3-dichloro-1,3-butadiene (II) and 10.6-0.2 (6.5-0.5) wt. % 1-chlorobutadiene (III). The polymers have a Mooney viscosity of 10-140, (30-120). (II)+(III) result in a much lower crystallisation speed of the polymer than when (II) and (III) are used on their own as comonomers. The low temp. stability of the polymer is improved without adverse effects on the mechanical props. of vulcanisates.

Title: Isolation of antiinflammatory cpd. from grape seed oil - by dissolving in solvent, cooling, filtering and evaporating
IPC: A61K36/00
Filed: 1976-12-08
Abstract: For antiinflammatory substance is isolated from grape seeds by dissolving grape seed oil in polar solvent having a m.pt. below 60 degrees C and separating the substance which has an antiinflammatory value of below 5.
