Abstract: 1,196,899. Joining ceramic articles; shaped alumina articles. THORN LIGHTING Ltd. 18 April, 1969, No. 20031/69. Headings C1A and C1J. The tubular envelope of a discharge lamp is made from a sub-micron, ball-milled alumina powder, containing a small amount of magnesia, by isostatic pressing at 5 tons per square inch and firing at 1100‹ C. to a density of 1À84 gm. cm<SP>-3</SP>. Some of the same ball-milled magnesiacontaining alumina powder is spray dried from an aqueous suspension, which can contain an organic binder, to produce spheroidal particles having a higher bulk density than the ballmilled powder. End plugs for the envelope are made by compacting the spray-dried powder at 5 tons per square inch and firing the compacts at 1100‹ C. to a density of 2À15 gm. cm<SP>-3</SP>. The plugs are machined, if necessary, to fit tightly inside the envelope and the envelope and plug assembly is sintered in hydrogen at 1800‹ C. to a density of 3À95 gm. cm<SP>-3</SP>. The envelope shrinks more than the plugs to achieve a hermetic seal with grain growth across the interface. The plugs may have one or more holes for electrodes and/or exhaust tubes. The differential shrinkage can be controlled by using materials of different compositions; by pressing the plugs at a higher pressure than the envelope or by partially sintering the compacted plugs before machining.

Abstract: 1318076 Coating porous substrates CONSERVATOME 14 Aug 1970 [14 Aug 1969] 39318/70 Heading B2E [Also in Division C1] An article of porous material is treated by impregnating the article with polymerisable liquid, coating the impregnated article with a protective substance capable of producing a product under irradiation which is oxidisable by oxygen and polymerising the polymerisable liquid by irradiation. The protective substance can be a wax of mineral, vegetable or animal origin e.g. paraffin or microcrystalline waxes, waxes formed of esters of higher fatty acids or alcohol, carnauba and bees wax; fatty acids solid at ambient temperature e.g. a mixture of stearic and palmitic acid. These substances may be applied as melt, emulsion or solution. The protective substance may also be a solution in a monomeric liquid e.g. methyl methacrylate of a polymer obtained by hardening the monomeric liquid, the monomer being evaporated after impregnation; a strippable varnish e.g. a copolymer vinylchloride and vinylacetate, the coating of varnish being subsequently removed after irradiation; a solution of unsaturated polyesters in a polymerisable solvent. The porous material may be wood, plaster. The polymerisable liquid for impregnating the articles may comprise a solvent which is also polymerisable e.g. mono- or divinyl benzene and polyester, acrylic or urethane resins. As shown in (Fig. 2) blocks (1) of beech are separated by plates (2) of paraf-. fined cardboard or a polyethylene grill and are arranged in open work baskets (3) of aluminium or aluminium alloy. The assembly is then introduced into a container which is put under low pressure to degas the beech and the vessel then filled with polymerisable liquid. The vessel is then pressurized for 18 hours to impregnate the beech wood to its core. The baskets are then removed, drained and then inserted in aluminium containers into which is poured a bath of molten paraffin wax. The wax is then solidified into a block surrounding the wooden blocks and the container then subjected to an irradiation dose. The irradiation heats the wax block to the liquid state and polymerises the liquid which impregnates the beech. After irradiation the baskets are removed from the containers, cut into elements for making flooring blocks, and rubbed down or planed. The polymerisable impregnation liquid may comprise 20 parts styrene, 10 parts methyl methacrylate, 10 parts acrylonitrile and 60 parts of an organic resin prepared from 1, 3 propylene glycol, maleic anhydride and phthalic anhydride. In example 7 cylindrical elements of graphite are impregnated with a polyester resulting from the reaction of fumaric anhydride with bis-phenol in solution in styrene and soaked in a bath of liquid strippable varnish constituted by a copolymer of vinylchloride and vinylacetate dissolved in acetone. After drying the coated elements are subjected to irradiation and the coating of varnish subsequently removed. The elements are then transformed completely into graphite by baking at 800 to 1000‹C followed by heating to 2300‹C.

Title: Doppler detector for security monitor - includes transmitter and receiver having amplifier and demodulator
IPC: G01S15/52
Filed: 1975-03-18
Abstract: The Doppler movement detector for use as a burglar alarm or similar security monitor, having no resonant circuit, and therefore not affected by off-tuning drift, has a transmitter consisting of transistor (25) and associated components with crystal (32). The crystal receiver portion of the detector includes an integrated circuit amplifier (15) and a piezoelectric transducer (16). In normal operation of the detector, the transducer output signal is amplified and limited (15) to give a constant amplitude. Any attempt to interfere with operation of the detector results in a fall in the transducer output signal and consequently a fall in the amplifier output signal (10), to give an alarm signal.

Title: Electric shaver with counter mechanism - has nickel-cadmium cells in series with motor with drive mechanism operated by pushbutton and lever
IPC: B26B19/38
Filed: 1979-10-19
Abstract: The domestic electrical appliance, typically a shaver, is powered by four dry batteries, e.g. Ni-Cd accumulators, maintained in contact by a pressure spring. The electrical circuit is simply, the batteries, in series with a d.c. motor and a pushbutton switch. The main control is a cylindrical button (36) in contact with a spring loaded lever arm (37), which when depressed operates the switch and is limited by a stop (38). The appts. also includes a two-position switch, which in one direction (P1) causes a pawl (31) to engage in a gear wheel (17) so that the motor drive is coupled with the cutting heads. In the other position, the pawl is released so that the cutters do not rotate even if the motor is running. There is also a counter with a plastic number from 0 to 20 visible. This shows zero in the neutral position, and other numbers when the motor rotates to indicate the speed of movement and hence state of battery.
