Patent GB-1113696-A (GB)
Title: Improvements in or relating to brake operating mechanisms
Inventor: SCRIVENER EDWARD WILLIAM ARTHU
IPC: B60T7/10
Filed: 1964-11-11
Abstract: 1,113,696. Brake transmitting mechanism. SECRETARY OF STATE FOR DEFENCE, LONDON. 11 Nov., 1965 [11 Nov., 1964], No. 45990/64. Heading F2E. A quick take-up mechanism for the handbrake of a heavy vehicle comprises a planetary gear through which chain wheels 14 for operating the brake may be driven via a shaft 4, having an integral ratchet wheel 7, by repeated to- and-fro movement of a handbrake lever 16 which is pivoted on the shaft 4 and carries a spring-loaded driving pawl 23 co-operating with the wheel 7, there being a second, slidable pawl or detent 18 carried by the handbrake lever which on manual depression of a plunger 20 is engaged with a toothed wheel 15 formed integrally with the chain wheels, so that the latter are initially driven directly to take up slack quickly, after which the detent 18 is forced out of engagement with the teeth of wheel 15 so that during the setting of the brake the chain wheels 14 are driven via the planetary gear. The latter comprises a sun wheel 8 on shaft 4, planet gears 9 on a carrier 12 integral with the chain wheels 14, and a ring gear 10 which may be fixed or, as shown, be rotatable only in the direction of rotation of wheels 14 during brake application, by virtue of a one-way clutch 11, which results in rotation of the ring 10 instead of the shaft 4 during initial take-up of slack, so reducing effort and also noise (since the ratchet wheel 7 is not rotated rapidly in the brake-applying direction). To release the brake, which is held set by a holding pawl 28, the plunger is again depressed slightly and the handbrake lever can then be moved back beyond its normal rearward limit since lug 32 on detent 18 can now clear an abutment (33, Fig. 2, not shown). This simultaneously causes a peg 25 carried by pawl 23 to engage a ramp portion (27, Fig. 3, not shown) of a cam track formed in end plate 3 and also causes a cam formation on the handbrake lever to engage a peg 30 on the pawl 28, whereby both pawls 23 and 28 are disengaged from the ratchet wheel 7.

Title: Production of poromeric materials
IPC: C08J9/28
Filed: 1969-09-19
Abstract: 1,274,870. Producing poromeric materials; bonded fibre fabrics. BADISCHE ANILIN-& SODA-FABRIK A.G. 19 Sept., 1969 [21 Sept., 1968], No. 46198/69. Headings DIP and D1R. [Also in Division C3] A process for producing poromeric materials comprises (a) impregnating a flat fibrous structure with a liquid containing one or more monoolefinically unsaturated monomers and one or more high polymeric plastics materials in dissolved, emulsified or dispersed form, but no polyolefinically unsaturated monomers, (b) freezing the impregnated fibrous structure with complete or partial crystalline solidification of the liquid, (c) irradiating the frozen structure with electromagnetic radiation having a wavelength of less than 0.70Ám or ionising radiation to effect polymerisation of the monoolefinically unsaturated monomer(s), (d) thawing the frozen structure, and (e) separating said liquid from the resultant poromeric material. Suitable monomers include acrylate and methacrylate esters, acrylic and methacrylic amides and their N-methylol derivatives and ethers thereof, acrylic and methacrylic acids, vinyl carboxylate esters, vinyl ethers, N-vinyl caprolactam, N-vinyl carbamic acid ethyl ester, vinyl chloride, vinylidene chloride, styrene, vinyl toluene, vinyl thio ethers and also monomers containing one or more chromophoric groups, e.g. 1-amino-4-acryloylaminoanthraquinone-2-carboxylic acid 2-n-propoxyethyl ester. The medium in which the monomer is incorporated may be, for example, acetic acid, dioxan, benzene, water, trioxan or urea. The high polymer may be an addition polymer of a mono- and/or di-olefinically unsaturated monomer, or a polyester, polyurethane, polyamide, polyvinyl alcohol, polyalkylene oxide, polyacetal, polycarbonate, polyurea, cellulose ester or ether, or polyamine. When appropriate, the liquid may include a photoinitiator or photosensitiser. The fibrous structure may be non-woven e.g. spunbonded, woven or knitted fabric formed from materials such as wool, cellulosic, cellulose acetate, viscose, polypropylene, polyamide, polyacrylonitrile and/or polyethylene terephthalate fibres. The irradiation in step (c) may be actinic (including daylight or sunlight), or ionising such as electron beams, X-rays and radioactive radiation. Monomer conversion is generally from 60-90%. The products obtained can be used as floor coverings, thermal insulating materials, leather substitutes and coating materials.

Patent GB-1592892-A (GB)
Title: Electronic timepieces
IPC: G04C3/14
Filed: 1977-11-15
Abstract: In an analog electronic watch having a calendar display the power required during change of the calendar display, about 6 hours out of 24, is greater than at other times. In order to effect economy in power consumption, the pulse for driving the watch motor during the time other than the period in which the calendar display is being changed is only sufficient to drive the time indicating means. In case the motor fails to step when such pulse is applied, this is detected by a detecting circuit and a corrective drive pulse is applied to the motor so as to drive it.

Abstract: 1,255,305. Safety helmet. H. F. PAYER. 6 Oct., 1970 [13 Oct., 1969], No. 47468/70. Heading A3V.  To ventilate the head of the wearer a safety helmet is provided with a conduit 16 between the rigid outer shell 12 and the impact absorbent liner 14, holes 22 in the liner communicating between the conduit and the space for the wearer's head, and a vent 20 communicating between the conduit and the outside atmosphere. When in use on a moving motor cycle reduced pressure is developed at the back of the helmet by the flow of air from front to rear so that air is removed from the inside of the helmet through the conduit to be replaced by fresh air. The vent in the shell may be either in the rear facing surface near the base, or down-facing in the base of the helmet. The conduit may consist of a groove in the surface of the liner or a space created between the liner and the shell by the use of spacers. A sliding closure may be provided for the vent, to control the flow of air through the conduit.

A guide cage which automatically severs material to be rolled when a deformed or faulty portion of the material enters the guide cage, as defined in the parent Specification, includes a catch which holds the guide in position until a predetermined pressure is exerted on the catch by the workpiece. A further severing means may be incorporated on the entry side of the guide cage so that the faulty portion is completely severed from the material. As shown, a spring loaded ball 16 is urged into a recess 17 in a guide 2, the ball being dislodged from the recess when a deformed piece of stock forces the guide to the right. A sliding cutter 6 is moved to the right by the guide and co-operates with a similar cutter to shear the stock. A screw plug 18 adjusts the value of the force which is sufficient to shift the guide.

The third conduit may be arranged, e.g. as is 24, to transfer water from the first vessel to the hot zone of the second vessel or it may be arranged as is 32 to transfer water from the first vessel to the cold zone of the second vessel. The fourth conduit similarly may transfer water, as does 26, from the hot zone of the second vessel to the first vessel or, as does 34, from the cold zone of the second vessel to the first vessel. In a preferred embodiment the system incorporates a third exchange vessel, e.g. 12, the same size as the first vessel 10, the two being similarly equipped but vessel 10 is adapted to transfer and receive water from the hot zone of vessel 14 and vessel 12 transfers and receives water from the cold zone of vessel 14. Each transfer is such that a net transfer of deuterium oxide takes place to vessel 14. In operating the process the two fluids may be hydrogen sulphide and water. The two vessels 10 and 12 may be mounted one above the other as a single unit (Fig. 2, not shown) and two such combinations of vessels, 10, 12 and 14 may be linked to feed an even longer hot and cold exchange tower for even further concentration (Fig. 3, not shown).
