Patent FR-2473467-A1 (FR)
Inventor: RIEDERER HANS GIAN
IPC: B65B59/02
Filed: 1981-01-09
Abstract: The device for feeding articles intended for boxing, and their boxing means along a boxing line of a packaging machine comprises a uniting zone (V) where the articles (10) to be boxed are fed together with an unfolded box (11), whereupon the boxing then takes place in a boxing zone (E) and subsequently delivery transport takes place under the effect of a pressing power for glueing the box (11). In this case, means are provided in the uniting zone (V) for producing a synchronous transport speed between the articles (10) and their boxing means (11). Furthermore, means are provided for the rapid adjustment of the clear width between pairs of pressing-on and carrying members (6, 8) for the boxing processes (10, 11) and means for synchronous accompanying adjustment at least of the carriers (4) for the boxing means (11). These measures allow rapid readjustment or correction of the machine in the case of changing products or changing operating conditions.

Title: Continuous casting installation - with gas injection to prevent metal solidification before entering the mould
Inventor: PIETRYKA JOSEPH
IPC: B22D11/04
Filed: 1981-03-11
Abstract: In a continuous casting installation the mould is connected by a closed channel to the reservoir of molten metal. An inert gas is injected under pressure across the inner surface of the channel adjacent to the mould. This produces local turbulence in the molten metal and prevents it solidifying on the channel surface. The gas may be Ar or N and the flow across the surface is at least 0.01 litres per cm2 per second. It is introduced through an annulus of porous material set in the channel lining. An annular duct behind it is connected to the gas supply. As solidified metal is extracted from the mould, any which has started to solidify at the surface of the connecting channel is pulled off and partially remelted in the molten centre. This tends to produce unacceptable cracks and to erode the refractory lining, giving rise to inclusions. The configuration of the connecting channel allows gas bubbles to escape without entering the mould, via the free surface of metal in the reservoir, or by gas outlets.

Abstract: Plastic containers are made with a base profile having a rigid centre linked to the root of the vessel walls by a flexible section shaped to be self locking with the centre of the base alternatively higher or lower than the plane of the bottom of the walls. Used esp. for containers blow-moulded from polyethylene for contg. mixts. with volative or fugitive constituents, typically perfumes or cosmetics. The container can be filled with the base distended, leaving sufficient void above the contents for the base to be impressed after fitting the closure. The resultant pressurisation within the container suppresses partial local collapse featured by such containers after partial loss of their contents by permeation. Used to maintain aesthetic appearances longer.

Title: Alternating rotary drive for shaft - uses jack between crank and pin joint common to fixed fulcrum pivot arm and sliding pivot arm
Inventor: GIRAUD RENE
IPC: A01B3/421
Filed: 1981-06-18
Abstract: The jack (C) effects the automatic reciprocal half turn rotation of a shaft, to reverse tools such as ploughshares. One end of the jack is pinned to a shaft crank (B) of which the reciprocal movements are limited by two stops (1,1'), the other being pinned to an end of an arm (E) secured by an axle pin (3) in a slot hole. The axle (4) securing the arm to the jack also locates the ends of a pair of pin-jointed connecting rods (D) extending to a fixed fulcrum (2), locating the rods with a degree of float. The rod causes reciprocal displacements of the jack from one side to the other of a vertical plane, the strap obviating jamming whilst permitting the centre of gravity of the tools to pass through the upper dead point for jack inversion.

Title: Electronic pre-ignition detection system for motor vehicle - uses microprocessor to calculate advance ore retard to avoid pinking form vibration and flywheel position sensors
Inventor: LATAPIE JEAN-FRANCOIS
IPC: F02P5/152
Filed: 1981-07-30
Abstract: A vibration sensor (2) is located on the cylinder head and an angular position sensor (3) on the flywheel indicates passage of TDC of each cylinder. A depression sensor (4) is located in the inlet to the cylinders. The vibration sensor output passes through a gate (5) which is open for an angular window for one of the cylinders. The gate output is amplified and filtered (6) to allow pre-ignition noise frequencies to pass to a detector (7) followed by an integrator (8). The integrator output passes through an A/D converter (9) to a microprocessor (10) which receives inputs from the other sensors. The microprocessor determines when the angular window should occur and opens and closes the gate circuit. The microprocessor calculates the ignition advance or retard and provides a control signal to switch the ignition coil (17) primary circuit.

Title: Ridge valley channel for collecting rain
IPC: E04D13/04
Filed: 1982-11-24
Abstract: The invention relates to a technique for collecting rainwater on roofs, particularly for those in which the roofing material is vegetal. The device comprises, instead of conventional roof ridges, a valley channel consisting of a trough in the shape of a "V", or similar shape which is flared and has a flat bottom, with two sides or wings having harmoniously chosen inclinations, and the bottom having one or more sloping lines for collecting the rainwater and conveying it towards discharge pipes leading to one or more storage tanks. In the attached diagrammatical figure, the trough is a half-parallepiped (or similar volume) with base DFE and D'F'E' and sides DFF'D' and EFF'E', open on the side DEE'D'. The trough may comprise one or more overflow devices. The slopes may be covered with photovoltaic panels or solar collectors, and may comprise turned-down strips forming a drip moulding on the roof slopes. In a variant, the tank or tanks are housed in shells or floats supporting a structure which is thus allowed to float. The invention makes it possible to provide a total or partial independent supply of cold or hot water and of electricity, for certain domestic or craft-related uses.

IPC: B22D11/06
Filed: 1983-02-25
Abstract: The present invention relates to a method of manufacturing steel sheets or plates, in which molted steel is fed into a continuous casting machine of the type with twin conveyor belt for casting thin panels, in which cast panels are cast, and subsequently sheets or plates are manufactured from the thin cast panels obtained. The raising of the cast panels can be prevented by the selection of the coefficient of the solidifying speed of the casting machine for thin panels, of the thickness of the cast panels and of the thickness of the sheets or plates within the stipulated range, as a result of which sheets or plates of high quality and without the defects caused by raising can be manufactured. Additionally, the production installations can be simplified.
