Title: VTOL aircraft with retractable exhaust deflexion flap - has air feed into flap which is pivotal downwards and forwards
Inventor: HOOPER RALPH SPENSER
IPC: B64C29/00
Filed: 1975-08-01
Abstract: Undesirable recirculation of exhaust gases to the engine intakes on the VTOL aircraft is prevented by the blown flap. The flap (5) is fitted forward of the jet pipes (1, 2) and may be retracted during cruise flight. When on or close to the ground, it is extended downwards and forwards. Air is supplied from the engine compressor via the flap hinge (6) and discharged through slots around the lower quadrant of the edge of the flap in a forward and downward direction. This air sheet entrains the exhaust gases and directs them along the ground away from the air intakes. It is also possible to use the flap as an air brake, in which case, it is only partially extended and not blown.
Patent FR-2326904-A1 (FR)
Title: Arterial blood pressure measuring device - has suspended pressure sensitive cushion connected to gauge
IPC: A61B5/022
Filed: 1975-10-10
Abstract: A pressure-sensitive cushion (18) is connected to a pressure gauge, so that the humeral artery is between the humerus and the cushion. The cushion is held in place by a support (10,12,14,16) in opposition to the weight of the arm. This weight is varied by the patient, and the gauge readings are recorded as the pressure on the cushion alters. The pulsations in the artery can be examined by palpation, listening or visually downstream of the cushion, the gauge readings being noted when arm weight causes pulse modifications typical of maximum and minimum arterial pressure.
Patent FR-2334468-A1 (FR)
Title: Grinding and polishing machine for tools - has setting micrometer for adjusting automatic tool feed in each operating position
IPC: B24B3/34
Filed: 1975-12-10
Abstract: The grinding and polishing machine is for tools, esp. hard metal chisels. The axes of rotation of the grinding disc and polishing disc are parallel and arranged on a support which moves on the machine frame. The support can move between two operating positions in which one of the two discs is applied to the tool. There are setting micrometers (34,36) for adjusting the automatic feed for the tool faces and the corresponding disc work face in each operating position of the support (2,32). This compensates differences in the disc dimensions and eliminates danger of damaging the tool (5,35) and the discs (3,4) on transferring from one operating position into the other. One disc has an axis of rotation which can be moved axially between two given positions to bring the two working faces of one of the discs into the place of the machining face of the other disc.

Title: Fluid filter with jet cleaning arrangement - the filter moving relative to the cleaning slit, enabling all the filter area to be cleaned during filtration
IPC: B01D36/00
Filed: 1976-05-20
Abstract: A fluid filter comprises a permeable filter wall mounted on a drum around an axis and a cleaning jet which is sprayed from a slit in a tube which extends along the axis of the filter. The filter drum and the cleaning tube can be displaced relative to each other, the relative movement being such that the jet sweeps the whole of the filter. The filter is enclosed in an outer wall, the liquid being filtered entering at the top, passing through from the outside to the interior of the filter drum and leaving the filter at the bottom. The arrangement allows sections of the drum to be cleaned separately. It is possible to use either already filtered fluid as the cleaning medium or alternatively a succession of fluids may be fed in which clean, rinse and dry the filter. It is possible for the cleaning operation to be carried out simultaneously whith the normal operation of the filter as long as the cleaning fluid is non-miscible with the filtrate.

Title: Lever handle for motor vehicle door - acts as door operating handle and door latching mechanism operating lever
IPC: E05B65/20
Filed: 1976-07-23
Abstract: A handle for opening and closing a motor vehicle door is combined with the locking lever mechanism so that successive movement of the lever handle will cause the door latching mechanism to operate. A lever handle assembly comprises a casing (1) which fits into a door. It comprises a button (3) mounted alongside a handle (4) which both pivot about a common axis (5). The button has faces (14, 15) to press against for latching and unlatching lock operations by moving a remote control shaft (10). Initial movement (F1) of the lever handle (4) tail (8) is dead travel until a finger (18) moves to the end of a slot (17) in the button body.

Title: Conversion of liquids or solids into solid adsorbates - for prepn. of solid pharmaceutical compsns.
IPC: B01J20/28
Filed: 1976-09-08
Abstract: Conversion of one or more liquid or solid substances into a solid adsorbate on one or more adsorbents is claimed in which a non-solvent cpd. for the substance is added to a suspension or soln. of the adsorbent in a solvent contg. the substance to be adsorbed, the solvent being miscible with the non-solvent cpd. Used esp. for converting liquid active principles or excipients into substantially homogeneous solids which may be converted into conventionally solid pharmaceutical compsns., e.g. by granulation, tabletting, coating, etc. Typically, vitamins A and D2 were dissolved in water and carboxymethylcellulose was added. The suspension was stirred until quasi-homogeneous and spray-dried using N2 to give a fine powder with quantitative recovery of vitamins.
Patent FR-2327743-A1 (FR)
IPC: A47B73/00
Filed: 1976-10-13
Abstract: The device has a plate (2) with openings (3) into which bottles can be inserted by their necks. The openings (3) are dimensioned such that the thickened edge of the bottle can just be pushed in, with the result that the bottle neck is held with a small amount of play. Instead of openings (3) in a plate (2) clearances (11) for inserts (8), which have openings (17, 18) for inserting the bottle necks, can also be provided. The thickness of the plate (2) for directly holding the bottles or the length of the inserts (8) holding the bottle necks is selected such that the bottles are essentially held in the horizontal direction.
Patent FR-2569160-A1 (FR)
Title: Heliplane
IPC: B64C27/00
Filed: 1976-11-04
Abstract: Device allowing vertical and oblique take-off by an aircraft. It comprises a rotor equipped with blades 1 having lenticular cross-section capable of taking up a positive or negative incidence:   - a peripheral reservoir in the shape of a flattened revolution torus 2; - a hollow shaft 3 equipped with bearings 4 allows the link with the aircraft; - the axes of the blades 5 allowing the rotation of the latter are controlled by a rod 7 which transmits the movement to the inside of the aircraft.   The principle of the system consists in storing sufficient kinetic energy to permit the support of the aircraft during the few seconds necessary to obtain a horizontal speed, the moment from which it behaves like an aircraft. The invention can be used for taking off and landing of light aircraft. In the course of research, it appeared that it could also be of interest to the military.
Patent FR-2371804-A1 (FR)
Title: Medium tension radial field electric cable with resin-contg. coating - having uniform electric field at extremity to obviate electric discharges during use
Inventor: PAUL
IPC: H02G15/068
Filed: 1976-11-18
Abstract: The end of a radial-field medium-tension electricity cable consists of is not 1 metallic core, an insulating envelope, a semi-conducting envelope a metallic screen which is uncovered up to a short distance from the semi-conducting envelope (the latter itself being uncovered w.r.t. the insulating envelope along a length detd. by the operational voltage), and possible an exterior protective sheath. To reduce the impedance near to the end of the semi-conducting layer, a high-permittivity coating is deposited on the end of the cable in the vicinity of the semi-conducting layer. The system produces a more uniform electric field along the end of the cable. This is desirable when preparing such cables for adaptation to others, since otherwise there is a concn. of the electric field in these areas, creating insulating zones along the insulating layer and leading to the danger of electrical discharges during use. Previous methods have not overcome this problem, the present method does so by reducing the electric field by deposition of a crating with specific electrical and chemical props. The coating pref. contains epoxy, polyester, or polyurethane resin and may be fixed by e.g. polyethylene or polypropylene grill.
