Title: Shock absorber for vehicle engine mounting - has resilient elastomeric block with differential cavities to absorb high and low frequency vibrations
IPC: F16F13/18
Filed: 1978-12-07
Abstract: The shock absorber has a resilient block (1) secured between an upper plate (9) and a lower plate (3). The two plates retain securing screws for attachment to the vehicle chassis and engine casing. The block incorporates a main central cavity and two auxiliary cavities (5 6) which are shallower and forming curved arch seen from above.

Title: Safety fitting for drilling pressurised pipe - includes dash-pot arrangement with sealing ring in socket to damp movement of drill supporting sleeve when pipe is pierced
IPC: F16L41/04
Filed: 1979-06-21
Abstract: This device is used in conjunction with a branch pipe already welded to the main, prior to the main being drilled. An 'O'-ring seal (6) ensures the gas or water tightness of the fitting. A shaft (2) carries a drill-bit at the lower end (2a) and is rotated with a ratchet spanner engaging with the squared end (2b). To commence drilling the outer sleeve (8) and socket (14) are lowered. The drill bit is rotated and simultaneously advanced by screwing down the knurled cap (14). The fitting is locked in the upper and lower positions by four ball bearings (9) locating in grooves (10) or (11) and held by the locking ring (12). A sealing ring (17) has an orifice (17a) so that a dark dash-pot exists either side of the sealing ring. This slows down the movement of the sleeve when the pipe, under pressure, is pierced.

Title: Ballistic screens partic. for bulletproof sheeting for car body mfr. - incorporates laminate of fibrous materials combined with metal sheet, light in wt. and thin
IPC: B32B21/10
Filed: 1979-06-26
Abstract: Ballistic screen partic. for the realisation of bullet proof sheeting used e.g. for the making of car bodies of the kind formed from a lamination, comprises at least two layers of fibrous material placed on either side of a core and joined to it by a polyester resin. Core is made of material of low density and high plasticity. These layers form structures for one side of the core which are plastically deformable under the impact of a bullet because of the plasticity characteristics of the core. They also form a cushion for the other side of the core, these plastically absorbent strata being combined with screens of high density and resilience. They are pref. coated on the impact side with a gel coat which is in contact with the wall of the protective material, e.g. a metal sheet. Material weighs less per square m than existing materials, and it is thinner, this fact facilitating its putting into place and its presentation in the form of sheets which can be cut up or preformed. It is suitable for forming in contact with a thin metal sheet a safety complex partic. well adapted to the motor car industry, but also car screens for all uses.

Title: Telephone set having earpiece amplifier - whose gain can be preset by user by dialling selected code using phone dial or pushbutton keyboard
Inventor: DUONG TUAN-KIET
IPC: H04M1/60
Filed: 1979-06-29
Abstract: The subscriber phone, e.g. push button, includes an amplifier (14) and loudspeaker or earpiece (18) the sound level of which can be regulated using keys 1 to 4 of the phone keyboard (20). The loudspeaker is driven through a transformer (64) by two operational amplifiers (60,62). The value of a feedback and input resistor chain (66,72) is controlled by two switches in turn controlled through separate lines from a decoder (50) of a gain control circuit (26). The decoder converts the output signal from four bitables (B1-4) into a two binary elements to control the switches. Each bistable setting input is connected to a respective one of the keys (1-4) while the resetting input is connected through an AND gate to the other keys. A supplementary key (G) is pressed by an operator to achieve the regulating system.

Patent FR-2466448-A1 (FR)
Inventor: HARDY NICOLAS
IPC: C07C51/09
Filed: 1979-10-01
Abstract: A process for the recovery of carboxylic acids from mixtures containing glycol esters derived from these acids. The process comprises reacting these mixtures at boiling with water to form carboxylic acid and entraining the carboxylic acid formed by means of the water by azeotropic distillation, so as to separate off a mixture of carboxylic acid and water. This mixture is subjected to extractive distillation by means of an organic solvent which is insoluble in water and in which water is insoluble. A mixture of water and organic solvent is thereby separated from a solution of carboxylic acid in the organic solvent.

Title: DIY adjustable work table - uses twin pin-jointed X-frames support with tie to movable leg heads guided by slots in cross beams
IPC: B25H1/14
Filed: 1979-11-30
Abstract: Designed primarily for use by the amateur handyman, the worktable provides a full width vice with reference holes and stops for mitring etc. It is adjustable for height and inclination. Occupying parallel vertical planes beneath opposite sides of the worktop, the legs constitute twin pin-jointed 'X' frames connected by toe rails. The nearside leg head of each frame is pinned to a cross beam, with the outer heads connected by a tie rod. The rod can slide in co-planar horizontal slots in each of the cross-beams, thus modifying the angle of each 'X' frame to vary the table height. Slot notches locate the rod at definite alternative positions with locking effected by means of a wing nut. A 'U' shaped and notched slot extension enables the top to be set at a definite inclination.

Title: Over-voltage protection circuit for power transistor - has zener diode passing extra current through current regulator to causes blockage of transistor
Inventor: SUQUET MICHEL
IPC: H03K17/082
Filed: 1980-02-12
Abstract: The power transistor (10) is connected by its collector to a conductor (12) supplying the supply voltage (+V) via a load circuit (11). The emitter is connected to earth via a current measuring resistor (16) and via a terminal (18) to a current control circuit (17) whose output is connected to the transistor base (19). The base also receives the input signal. The emitter is also connected to the supply line (12) via a zener (14) and resistor (13), the common point of these two being connected via a filtering capacitor (15) to earth. During a short voltage surge, the capacitor filters the over-voltage and the zener remains blocked. The transistor tolerates this since it is short. During a long voltage surge the zener (14) becomes conducting and blocks the transistor by means of the current regulator (17). In effect the regulating circuit detects a strong current and blocks the transistor.

Title: Domestic hand loom - with heald eyes inserted between dents in reed, to simplify lifting
IPC: D03D29/00
Filed: 1980-04-02
Abstract: Hand loom for domestic use has sliding rings or heald eyes inserted between the teeth or dents on the reed. The shed is formed by lifting individual heald eyes in the reed. There is thus only need for a single heald frame, which doubles as a reed. Deep sheds, to accommodate multiple heald frames are no longer necessary. The process of drawing-in or threading-up is simplified, as all the heald eyes are in the same plane.
