Patent GB-1036041-A (GB)
Title: A process for the production of sheet-like elements
IPC: D21F9/02
Filed: 1964-09-15
Abstract: Sheets are made from polyamide fibres by treating on a papermaking machine an aqueous dispersion of fibres of which 10 to 100% by weight are copolyamide fibres which soften under the action of heat in the presence of moisture, and then subjecting the formed fibrous web in the moist condition to a heat treatment to stick the web.  The copolyamide may be one formed from hexamethylenediamine adipate and caprolactam.  Other fibres may be present, e.g. of polyhexamethyleneadipamide or polycaprolactam. The heat treatment may be by guiding the moist web without tension over a heated rotating cylinder, or by infra red radiators.  The product can be paper-like or fabric-like, porous or transparent.

An electrically-heatable ceiling includes a plurality of panels, and a plurality of separate individual heating elements arranged to heat respective panels and fed by a supply harness having a connector for each heating element, whereby the heating elements are readily removable from the ceiling. A separate electric heating mat, constituted by an insulated conductor 13 held in sinuous form by stiff insulating tapes 14, rests on each of the suspended panels 11 of a ceiling, is overlain by an acoustically and thermally-insulating pad 17 of mineral wool, and can be plugged into a corresponding socket 19 in a supply cable 18, which includes a thermal or electrical cut-out 20 and a thermostat. The separate mats may be connected in series or parallel, and cable 18 may include additional sockets for lighting units. Instead of heating mats 12, pads formed by enclosing a heating wire between two sheets by insulating material may be employed. Specification 932,699 is referred to.

Title: Improvements in or relating to Safety Shaving Razors
Inventor: WILLIAMS JOHN
IPC: B26B21/44
Filed: 1966-08-23
Abstract: 1,157,640. Razors. CALMIC Ltd. 16 Aug., 1967 [23 Aug., 1966], No. 37764/66. Heading B4B. A safety razor for use in hospitals comprises a holder for a two-edged razor blade, a handle secured to or mounted on one side of the blade holder, and an applicator for a hair softening agent on the other side of the blade holder, the applicator covering an area between 30% and 80% of the surface area of the said other side of the blade holder and being in the form of a pad of real or synthetic sponge material capable of holding a sufficient quantity of hair softening agent in sterile condition to enable a normal shaving operation to be performed. The applicator may be partly inset into a recess provided in the body of the blade holder, the walls of such recess defining a smaller area than that of the applicator in an expanded state. The applicator is preferably formed of a non-rigid synthetic material e.g. flexible polyurethane foam. The applicator may have applied thereto an antiseptic which may be in liquid or powder form. The applicator may be impregnated with an emollient, perfume, colourant or an agent to prevent or ameliorate razor rashes. The applicator may be impregnated with a hair softening agent in the form of water and/or shaving soap or shaving cream. The blade holder comprises a top plate 11, Fig. 2, and a back plate 21. The plate 11 has lugs 13, 13<SP>1</SP> and 14 which pass through holes 15, 15<SP>1</SP> and 16 respectively in the plate 21. The ends of the lugs 13 and 13<SP>1</SP> are partly flattened to prevent the plate 21 moving away from the plate 11. The lug 14 ends in a screwthreaded extension 18 on to which is screwed a handle 23. An applicator 19 is glued by adhesive 20 on to the plate 11. The plate 21 is formed with a platform with downwardly extending serrations 22. The top and back plates and the handle are manufactured by moulding so that they are disposable. The handle may, alternatively, be formed of metal in which case it is used repeatedly with different disposable blade holders. The razor may be pre-sterilized and packaged ready for use.

Title: Fluid-controlling safety valve
IPC: F16K31/34
Filed: 1961-10-24
Abstract: 947,531. Fluid-pressure servomotor control systems. W. JORDAN. Oct. 24, 1961 [Nov. 8, 1960], No. 38008/61. Heading G3P. [Also in Division F2] A safety valve having its outlet 3 connected to a container to be filled, has its movable spring- loaded closure-member 7 unseated upon manually turning a cam 10, the member 7 being held open by an adjustable spring-urged catch 11. Should the pressure in the container and hence the outlet 3 rise above a given level, a float valve 35 is lifted from its seat 31 and fluid in the outlet passes into an insert 30; since the valve 35 is connected by a rod 36 to an upper valve 34 the latter is faced on to its seat 33 so sealing off the upper end of an oval pipe 25 from atmosphere; the pipe 25 opens into the insert 30. As the fluid level rises in the insert 30 and pipe 25 the air above the fluid is compressed until its pressure is sufficient to actuate a diaphragm 19 and release the catch 11 whereby the member 7 closes; the pipe 25 is connected to the diaphragm chamber by a tube 23 and a channel 21. The catch 11 may be released manually by a pin 37. A lever is provided for manually unseating the valve 35 to permit any fluid in the insert and pipe to drain away. The pipe 25 embodies a number of inspection windows, a flame filter 27 and a flap 28.

Filed: 1945-01-06
Abstract: 576,319. Admitting auxiliary fuel &c. THOMAS, A. Jan. 6, 1945, No. 381/44. [Class 7 (ii)] [Also in Group XXXIV] Lubricant or other liquid is supplied from a reservoir 3 to the induction pipe 2 of an internalcombustion engine through a flexible pipe 10 and a valve 1 having a spring pressed cylindrical valve member 7 operated through a Bowden cable mechanism 4 by a knob 16 on the vehicle dashboard. The valve 1 is mounted by a screwed coupling sleeve 6 or elbow piece on the pipe 2. The outer member of the mechanism 4 is anchored to a plate 15 clamped to the valve body and the inner member by an adjustable connection 14 to the valve rod 8. The pipe 10 may extend to near the bottom of the reservoir 3 and be fitted with a control valve. Alternatively the valve may be mounted on a T-piece having a connection to a suctionoperated device. In another construction the movement of the member 7 uncovers in succession two openings of different sizes in the valve 1 connected to different supply reservoirs, the first opening uncovered being of smaller size so that when both openings are uncovered, liquid will only enter through the second opening. The valve member may be coupled to the ignition switch or other engine or vehicle control member.

Title: Improvements in or relating to Rotary-wing Aircraft

Abstract: 1,182,339. Fluid-pressure servomotor systems. SUD AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Aug.18, 1967 [Sept. 16, 1966], No.38197/67. Heading G3P. Vibrations aboard a rotary wing aircraft are attenuated by measuring accelerations on the aircraft, generating phase-shifted electrical signals from the vibrations, converting the electrical signals into hydraulic signals by means of an electro-hydraulic servo-valve, and transmitting the hydraulic signals to a double-acting jack 3, Fig. 1, interconnecting the rotor support B to the fuselage F. As accelerometer 1, which may consist of an extendible wire in a Wheatstone bridge, feeds a demodulator 7 and an amplifier 9 having part of its output fed back through a frequency selective loop 10. The frequencies to be attenuated are passed through a phase-advancing network 12, a modulator 13 and an amplifier 14 and through a shunt circuit consisting of a modulator 15, an amplifier 16 and a gain control 17. The combined outputs are then amplified at 20 and energize the winding 24, Fig. 4, of the electro-hydraulic servovalve 22 which creates pressure differentials in conduits 29, 30 to operate a three-spool relay valve (not shown). The latter is connected by helical springs to a device which may be manually adjusted by a screw to centre the valve, and is mounted on the body of the jack 3 which also carries a differential pressure sensor 23, providing a feedback 21 to the amplifier 20. When the jack forms part of the support for the box B, its lower end is secured to the fuselage by an adjustable coupling bridged by an oval elastic ring. A leak monitoring duct is provided in the jack.
