Patent FR-2164526-A1 (FR)
Title: Moil removal - from hollow glass bodies
IPC: C03B33/095
Filed: 1971-12-24
Abstract: Apparatus for cracking off moil from hollow glass articles is arranged to receive rows of moulded glass articles as they leave a lehr and transfer them into a single line conveyor, which feeds them to a rotating turret on a crack-off machine using a feed screw and transfer wheel which presents the articles in turn to a crack off device and then to edge polishing nozzles. The articles are then fed into an annealing machine, and are rotated on the crack off chucks on which they are heated on the rotating turret. The crack-off device comprises a heating flame directed at the articles along a predetermined line at the top edge of the required position, a rotating cutting knife to strike the heated part, operated by an air blast, and a cushioned drive. The apparatus is especially for use with thin glass tumblers which require no mechanical finishing or polishing and is adapted to fast efficient throughput.

IPC: B65B53/06
Filed: 1972-08-01
Abstract: A plastic cup formed from a thin disc (e.g. 3/10 mm thick) which has been cold formed to provide a peripheral skirt 5-200 mm deep is located over the mouth of a pref. sterilized container filled with liquid, and the cap is heated (pref. in a direction from the lower edge of the skirt to the upper edge) by e.g. a hot air jet at 240 degrees C to produce a preliminary contraction after which cap tightens the skirt around the upper edge of the container. Pref. the skirt is then cooled by cold air whilst the flat part of the cap is heated with hot air at 240 degrees C) to contract it so that it is tensioned and pressed against the lip of the container mouth. Pref. the flat part of the cap and skirt are subsequently cooled by cold air. The method is suitable for an automated process for sealing containers having large mouths.

Title: Sealing access cover to nuclear reactors - by heating/cooling cranks abutting on top of cover to cause preloading
IPC: G21C13/073
Filed: 1973-01-26
Abstract: A series of cranks equally spaced around the periphery of a cover, abut at one end on a fixed support and at the other end at the edge of the cover. At the end adjacent to the cover, a wedge is placed between the end of the crank and the cover. Each wedge and the lower end of the crank have curved surfaces of radius equal to the length of the crank. By moving the wedges to increase the acting length of the crank, some preload is obtd. If alternate cranks are heated and the intervening cranks are not heated or are cooled, these can be moved to produce a much greater preload when they return to ambient temp. Alternatively all cranks can be cooled and then put into the prestress position to obtain a high prelaod. The cranks are arranged with internal or external pipes, passages or coils. Leak tight seal is obtd. over wide press. range.

Title: Method of fixing plastic mouldings to metal supports - plastic reheated after assembly forms internal lug engaging support
IPC: A47C5/06
Filed: 1974-01-29
Abstract: Thermoplastic materials may be attached in an irreversible manner to metallic supports by using the technique described. It avoids use of screws which may loosen due to vibration and prevents deliberate dismantling of, for example, classroom furniture which may be produced in (4) in the portion to be covered by the plastic.

Abstract: 1490594 E-M wave filtering device THOMSON-CSF 8 Aug 1975 [9 Aug 1974] 33246/75 Heading H4A A low-pass filter which passes e-m waves of frequency below a cut-off value while reflecting higher frequency waves comprises a dielectric sheet substrate 1 supporting parallel alignments 2-6 of metal elements on one of its faces and alignments 7-13 on its other face. The element length is just less than half the wavelength at the desired cut-off frequency. The orthogonal arrangement of the alignments as shown provides a double polarization of the waves. If the central part of each element is made wider or narrower than the remainder, the slope of the filter attenuation-versus-frequency characteristic is reduced or the cut-off frequency is reduced, respectively. Substrate 1 may be flat or curved. The filter may be used as a curved reflector for the high-frequency band of a dual-band antenna, while passing the low-frequency band without significant attenuation. Substrate 1 is a printed circuit board, a sheet of foamed dielectric, or a three-layer structure (having a cellular core).

Title: Fuel control system for gas turbine drives - uses fluidic oscillator and fluidic control throttle
IPC: G01F1/32
Filed: 1975-02-28
Abstract: The control system contains a fluidic oscillator, the oscillation frequency of which is a function of the fuel flow ratio through the oscillator.
