Title: Vacuum forming process
Inventor: SPRAUL JOSEPH ROBERT
IPC: B29C71/02
Filed: 1969-07-23
Abstract: 1278318 Sheet forming TRW Inc 23 July 1969 37139/69 Heading B5A Thermoset resinous articles are made by vacuum forming a sheet produced from a mixture containing a polyfunctional polydiene prepolymer having at least 50% and preferably at least 80% of its olefinic unsaturation in the form of pendant vinyl groups on alternate carbon atoms of an elongated backbone carbon chain, a polyfunctional organic chain extender capable of reacting with the functional groups on the polydiene, and a peroxide free radical initiator molecularly dispersed therethrough. The sheet is initially elastomeric and is slightly softened by heat and drawn into a heated mould where either it is retained and fully hardened by the crosslinking and cyclizing of the pendant vinyl groups by the free radicals released by the decomposition of the initiator under the influence of the mould heat and perhaps a radiant heater, or is partially hardened on the mould, removed therefrom and fully hardened using an independent heat source. The polyfunctional polydiene may be dihydroxy 1,2 - polybutadiene, dicarboxy 1,2- polybutadiene, dihydroxy 3,4 - polyisoprene or dicarboxy 3,4 - polyisoprene. Where dihydroxy substituted compounds are used the polyfunctional organic chain extender may be a diisocyanate, a diacid halide, a dicarboxy compound, or a diester substituted aliphatic or aromatic compound. Where dicarboxy substituted compounds are used, the polyfunctional organic chain extender may be a diepoxide, a diimine, a dihydroxy compound, or a diaziridene substituted aliphatic or aromatic compound. The peroxide free radical initiator may be an aliphatic or an aromatic peroxide. The extender and prepolymer are mixed approximately stoichiometrically and the peroxide added in an amount ranging from 0À5-10%, preferably 2-6% by wt. of the prepolymer. The mixture may be sheeted by rolling the mixture direct using heated rolls or by first casting a slab from a liquid mixture and then kneading the slab between rollers.

Title: Improvements relating to means for the printing of characters
IPC: B41J2/22
Filed: 1950-06-23
Abstract: 786,024. Selective printing. DIRKS, G. June 23, 1950 [Oct. 1, 1948], No. 37203/54. Divided out of 786,021 [Group XIX]. Class 100(4) A printing body has a plurality of printing faces or elements in fixed relationship with each other and each adapted to print a part only of a character and means whereby a relative movement between the body and the paper causes successive elements to be brought serially into side-byside printing positions within the same letter space so as to build up a selected character. A bar 1 carries a diagonallyarranged row of studs or nipples 3 separated from each other by a distamce greater than the height of a character, Fig. 3, to be printed. As the bar 1 is advanced over the ink ribbon 8 and paper 7 it is pressed into printing contact e.g. under control of magnetic recordings, for various periods of time. Thus the element 9 of a character is the result of a comparatively long period of contact by the first nipple, elements 10, 11 and 12 are formed by three brief contacts by the second to sixth nipples in succession and the element 13 is formed by the seventh nipple. Multi-column printing could be performed by a number of bars operating side by side, or a single plate carrying side-by-side sets of nipples may co-operate with means for providing a selective movement of the paper towards the plate for those columns in which printing is to be effected. Specification 786,041 [Group XIX] also is referred to.

Title: Detection of movement in confined spaces
IPC: G01V3/12
Filed: 1972-08-09
Abstract: 1448814 Intruder alarms PEAK TECHNOLOGIES Ltd 8 Aug 1973 [9 Aug 1972] 37224/72 Heading G4N [Also in Division H4] An apparatus for the detection of movement of an intruder in confined spaces comprises a microwave resonant cavity G of Q less than 200 housing a Gunn diode and tightly coupled, i.e. greater than optimum coupling, to an antenna (Figs. 1, 2, not shown), the Gunn diode operating in its negative resistance region and connected in series with a load resistance R3 to act as an oscillator and a follow-up circuitry for monitoring current changes in the Gunn diode resulting from a disturbance of the antenna field. The input to the monitor circuitry may be derived from a power monitor diode D3 coupled to the Gunn diode and antenna or as in the alternative embodiment of Fig. 5 (not shown) from the series combination of the Gunn diode and the load resistor itself. The load resistance R3 may be replaced by the dynamic collector emitter impedance of a transistor (Fig. 6, not shown). In the event of intrusion, the output of an amplifier A1 coupled to the Gunn diode rises above a predetermined limit to turn on a transistor VT1 and turn off a transistor VT2 so as to de-energize a relay RL, and to activate an alarm apparatus which may be connected on a separate printed circuit board. Intrusion is also indicated by a light emitting diode GAS1. A Miller capacitor C12 associated with VT2 provides a delay action. The diode D3 may be replaced by a thermistor bolometer. The coupling between the resonant cavity and the antenna is adjustable by means of the probe 7.

Filed: 1928-12-17
Abstract: 322,360. Meissner, C., and Hunt, W. H. Dec. 17, 1928. Fish, dressing.-Fish to be sliced are guided through two pairs of spaced cutting members mounted one above the other, whereby longitudinal cuts are made on each side of the backbone, severance being completed by a third pair of cutting blades. A chain with lugs feeds the fish along the guide 1, and spring operated side centring means 2, 6 press against the sides of the fish. Springs 5 acting on levers 4 produce torsional effects in rods 3<c> which, through connecting bars 3b, tend to press inwards the guides 2. Final guides 6 have projections extending between the inner faces of the cutting discs to prevent the fins and tail from passing outside the blades. An auxiliary centring mechanism 9 for the fins and tail is pivoted above the guide, the ends extending between the inner faces of the cutters. The cutters consist of upper and lower pairs of rotary disc blades 10, 11, motor driven in a direction to drag the fish from the guide through the cutting mechanism, the blades being so spaced that the tail and fins can just pass between them. The fish is preferably on its back, tail foremost, the cutters being arranged so that the upper cutters 10 make a longitudinal double incision along the belly right and left of the medial plane almost to the backbone, and the lower cutters enter the back to make a similar double incision. Deflector plates 12, 13 with sharpened bevelled edges are arranged to strip the flesh from the backbone, final severance being effected by blades 15 working in slots 12d and 13<a> between the deflectors and plates 12<c>, 13<c>, Fig. 6. The flesh is directed into receptacles B, and the bones and tail fall from the severing blades 15 into another receptacle. A. A single motor drives the shafts for the two pairs of cutting discs and the severing blades, through sprocket wheel and chain connections.

Abstract: 1436109 Thermal insulation in cryogenic containers MARINE & INDUSTRIAL DEVELOPMENTS Ltd 7 Aug 1973 [10 Aug 1972] 37452/72 Heading F4P A cryogenic container comprises an outer structural shell 18 to the inside of which is applied a thermally insulating lining formed by a unitary cellular matrix of fluid-impervious plastics material, in the cells of which are located load-bearing thermally-insulating blocks 19, the plastics material having a higher tensile strength than that of the blocks 19. The plastics material can be applied in situ under, between and over the blocks. This could be a prepolymer and coupling agent in appropriate proportions, or a curable liquid synthetic elastomer composition. Curing or vulcanizing of the applied material is then effected in situ. In an alternative method, the lining is built from blocks of thermally insulating material individually enveloped in a fluid-impervious skin of a suitable elastomer. These are laid like brickwork on the inside of shell 18 and are bonded together by an adhesive based on a composition identical or similar to that used for forming the block skins and the adhesive composition is vulcanized. Vulcanization is accompanied by chemical crosslinking over all the joints so that the resulting cellular matrix is a unitary and integral structure. The cellular matrix is preferably composed of one or more urethane rubbers such as those with the Trade Marks " Adiprene " and " Hylivel ". The blocks 19 are foamed plastics blocks such as polyurethane foam blocks of various length and breadth dimensions ranging from 0À2 to 2 m. A fibre-glass mat can be embedded in the plastics cellular matrix as a reinforcement.

Abstract: 1408903 Fractionation STONE & WEBSTER ENG CORP 14 Aug 1972 [22 Sept 1971] 37865/72 Heading B1B [Also in Division F4] Hydrocarbons are fractionated (e.g. propane is separated from butanes and above) in a fractionating still comprising two sections of which one (4) is at 160-250 psia and bottoms temperature 145-195‹F and the other at a lower pressure, e.g. 75-140 psia and bottoms temperature 145-195‹F. The overhead from the low-pressure section is condensed (at 42), compressed (at 46) and supplied to the highpressure section. The bottoms from the highpressure section are divided, one stream is reboiled (at 12) and returned to the highpressure section, the other is decompressed (at 54) and supplied to the low-pressure section. The bottoms from the low-pressure section are divided, one stream is reboiled and the other taken off as product. Similarly the overhead from the high-pressure section is condensed part is refluxed and part taken off as product. Feed may be to either section or both (by lines 48 and 50), when the two feeds may be of different composition. This process reduces the temperature, and therefore losses by polymerisation in the bottoms, without the disadvantages of operating the whole column at low pressure. The two fractionating sections may be in a single tower (as shown) or in two separate towers.
