Patent FR-2262275-A1 (FR)
Title: Conical rifle grenade bullet trap - causes bullet friction and distortion before itself swelling outwards
IPC: F42B30/06
Filed: 1974-02-22
Abstract: The trap is inserted in the axial direction inside the tubular grenade tail, and externally is of truncated cone shape and internally cylindrical and conical, the large end of the cone in each case being towards the opening in the tail. Thus as the bullet penetrates into the trap it is subjected to progressively friction and distortion, before the trap itself starts to distort by swelling. The small end of the truncated cone section can be secured to a damper unit placed right at the base of the tail and absorbing part of the energy from the bullet when this strikes the trap, typically in the form of spring rings releasing at least 30% of the energy absorbed during distortion so as to give additional propulsive force to the grenade.
Patent FR-2237010-A1 (FR)
Title: Mechanical crash barrier rail - is self-tightening on columns yielding fully on vehicle colliding
IPC: E01F15/04
Filed: 1974-07-05
Abstract: The rail is for mounting alongside a road on a number of columns at regular intervals. The columns yield fully on a vehicle colliding with them, so as to absorb part at least of the shock, and the rail is self-tightening. The columns can be inclined, and yield in a direction parallel to the road, also at right angles to it. The rail can be attached to the columns above road level by devices yielding on collision, some at least of the columns being flexibly mounted on the ground. The rail can be of channel section, with the flanges at 30 or 60 deg. to the base, being attached to the columns by one of them. The sections of it can overlap, being so designed that they can move for a limited amount only in the lengthwise direction in relation to each other.

Title: Stacking unit for paper bags - contains single magazine supplied from above and below to give crossed stack
IPC: B65H33/08
Filed: 1974-12-10
Abstract: The unit forms stacks of counted paper bags or sacks located across each other, and thicker at one end. A continuous flow of bags, is divided into two parts, and conveyed via two paths to a common magazine. The bags are inserted from above on one side, and from below on the other side. One of the two part flows has to pass through a larger distance. This is so dimensioned, that both part flows reach the magazine at the same time. The bags are placed on a lower conveyor and are separated for upper or lower feed by a triangular block which is hinged to divert bag flow, as the bags are lifted and inverted on a large dia. transfer wheel. The arrangement forms even standing stacks of bags.

Title: Electronic ignition system for internal combustion engine - is especially suitable for high speed multi-cylinder engines
Inventor: SICLEN HOWARD E VAN JR
IPC: F02P3/08
Filed: 1975-08-21
Abstract: The battery (29) supplies current to the ignition circuit (1) which charges the capacitor (5). The circuit (13) releases a signal in phase with the engine speed which unblocks the silicon rectifier (11) causing the capacitors (5) to discharge through the primary winding (7) of the ignition coil (9) which generates a current in the secondary winding (15) causing a spark across the electrodes of the plug (3). The current flowing through the rectifier (11) generates a pulse in the transistor (27) in the voltage control circuit (17). The effect of the pulse is to recharge the capacitor (5) so that the sequence can be repeated. The system can be used with eight cylinder engines at speeds above 3000 rpm.

Title: Winding device for roving has hollow bobbin - with apertures through which suction is applied to hold roving on bobbin at start of winding
Inventor: GROSSI OSCAR
IPC: B65H65/00
Filed: 1976-04-02
Abstract: A winding device for winding roving onto a hollow bobbin supported between two bearings (3) includes a hollow pref. pivotal arm connected to a suction device the bobbin has a circumferential row of first apertures adjacent its end onto which the roving is initially fed by e.g. a traverse guide and a second row of apertures towards the centre the centre of the bobbin. At the commencement of winding the hollow arm pivots so that a semi-cylindrical hood on its free end is located over the second row of apertures whereby the suction with in the hollow arm sets up a reduced pressure within the bobbin. This produces a suction through the first row of apertures so that the roving fed initially onto the bobbin is held against the bobbin for the first few windings of roving on the bobbin. In an automatic winding machine where the bobbin is automatically doffed and donned a tin roving is consistantly fed to and held on the bobbin at the commencement of winding without manual intervention.

Title: Double seat valve with dual sealing spring - has coil spring moving over centre to operate valve closure and resistant to pressure fluctuations
Inventor: LEGRANDGERARD JEAN
IPC: F16K27/02
Filed: 1976-06-29
Abstract: The double seat valve has an inlet (9) and outlet (10) separated by the valve seat (3) and piston valve (7). The valve piston has an inner seat (37) sealed by the valve head (32) attached to the actuating rod (8). A helical coil spring (44) tends to lift the valve head (32) off the seat (37). With the piston valve (7) on its seat (3) the coned disc spring (47) tends to push the valve head (32) on to the seat (37) with a force greater than that of the coil spring (44). When the rod (8) is lifted upwards to open the inner valve (32), in order to open the main valve (7), the coned disc spring is deflected past its neutral position and then exerts an upward force which keeps the inner valve open.

Title: Wall mounted toilet roll holder with tear bar - has E-form with central static spindle and teeth cut on underside of outer leg
IPC: B65H35/00
Filed: 1976-09-14
Abstract: The roll-holder may be used with toilet or kitchen rolls, with a static spindle (2) which supports the roll and a tearbar (3). Continued traction on the free end of the roll causes the paper strip to lock onto the bar (3) and finally tear transversely at the point of contact. The holder may comprise a bar of 'U' shape (1, 4, 3) in plan and with members of a vertically elongated rectangular section. The spindle (2) lies mid-way between the legs (1, 3) of the 'U' and cantilevers from the bar (4) of the 'U'. One leg (1) of the 'U' may be screwed (1a) to a wall, and the other leg (3) of the 'U' with saw-teeth (8) along the lower edge (3a) comprises the tear-bar.

Title: Balanced flue gas heater - has control which operates electric igniter and gas valve from single manual lever
IPC: F24C15/00
Filed: 1977-01-06
Abstract: A balanced flue gas fired room heater has a burner (11) supplied through a gas distribution box (13). The box has two valves (34, 40) which can be depressed by a push rod (30) and also by an electro magnet (TM). The burner is lit by operation of a lever (25) which energises an igniter (28) through a piezo-electric generator (PE). The lever also depresses the push rod (30) to an extent which opens one valve (34) while closing the other. This admits gas to a throttling orifice (46) fed from a space (38) between the two valves. A reduced flow thus reaches the burner. When the flame is established a and the lever released a thermocouple (TC) energises the electromagnet (TM) to keep both valves open and admit full gas flow.

Title: Fabric treatment process - uses a foamed preparation contg. active component and wetting agent, applied to material surface by jet
IPC: D06M23/04
Filed: 1977-05-16
Abstract: In a treatment process to apply a prepn. to a porous substrate, such as a fabric, the prepn. is foamed to give a froth with a density of 0.005-0.3 g/cm3, and the foam is passed to an applicator jet. The substrate is passed continuously over and in contact with the applicator jet so that the foamed prepn. and the jet are moved together and the machine contact time is equal to or less than the equilibrium contact time. A present and controlled volume of foamed matter is applied to the surface of the substrate by the application jet to give the treated fabric. The treatment prepn. is composed of 5-75 wt.% a functional chemical, 0.2-5 wt.% foaming agent and 0-5 wt.% wetting agent. The remainder is water. The process can be used to treat fabrics, non-woven fabrics, paper or wood veneers. It can apply a flame retardant, a waterproof or water resistant cladding, a latex, a fabric softener, a lubricant, a hand builder, a dye or pigment, a lightener or bleach, a bonding agent or a scouring agent. The process is more economical as water extraction and drying are reduced so that less energy is required to finish the treatment process.
