Abstract: 1295114 Coating glass PPG INDUSTRIES Inc 23 Oct 1970 [27 Oct 1969] 50426/70 Heading C1M An apparatus for producing a coated glass by coating a newly formed ribbon of float glass comprises a bath 14 of molten tin or tin alloy above which is a reducing atmosphere maintained at a pressure just above ambient pressure, a spray chamber 43 beyond and segregated from the atmosphere which includes three spray guns 44, 45, 46, and an annealing lehr on the side of the chamber 43 remote from the bath and also segregated from the chamber 43. The spray guns are each mounted on a rod 47, 48, 49 to rotate about a vertical rod 50 and are supplied with non-volatilized coating composition through a flexible hose 56 and pressurized air through a second hose 58. The spray guns may be reciprocated across the glass ribbon by a bracket 52 which supports the rod 50 engaging a lug on a chain 41 which is driven through sprocket 40 by a motor 39. The motor, chain and bracket are mounted on a cross-beam structure 38 which is in turn carried by wheels 36 running on two spaced beams 33, 34 so that the spray guns and associated equipment may be removed from a position over the glass ribbon. Vacuum hoods 61 are provided fore-and-aft of the spray chamber 43 to remove excess spraying composition. The hoods extend upwardly to corresponding exhaust pipes 62, the hoods being carried by wheels 64 which ride on upper flanges 65 of beams 33. 34 and the pipes 62 carried by wheels 67, 68 riding on the lower flanges 69 of a beam 70. The hoses 56 and 58 are thermally insulated by being encased in a steel-reinforced, Teflon-lined, neoprene sleeve and the spray guns insulated by a glass fibre wrapping. (" Teflon " is a Trade Mark.) The spray chamber is segregated from the bath atmosphere and the lehr by curtains 30 and 32 respectively which may be made of flexible asbestos or glass fibre material. The apparatus may be used to carry out the method described and claimed in Specification 1,210,578, which Specification also contains a description of the present apparatus.

Abstract: 1295681 Polymerization catalyst dispersion IMPERIAL CHEMICAL INDUSTRIES Ltd 19 Oct 1970 [30 Oct 1969] 53262/69 Heading C3P  A polymerization catalyst comprising an organo-aluminium compound and a solid compound of a transition metal of one of Groups IVa to VIa is finely dispersed by using it to catalyse the pre-polymerization of a small amount of a branched monomer in the presence of cyclohexane, cyclohexene, benzene, tetralin or chlorobenzene, the branched monomer having the formula CH 2 =CH(CH 2 ) n CR 1 R 2 R 3  or CH 2  = CH(CH 2 ) m R 4  where n is 1 or 2, m is 0, 1 or 2, R 1  is hydrogen or alkyl, R 2  and R 3  are alkyl and R4 is cycloalkyl, cycloalkenyl or aryl (and may be alkyl-substituted). A minor amount of another monomer may also be used in the prepolymerization. The resulting catalyst dispersion, typically having particle size no greater than 2 Á, may be used, after the addition of extra organo-aluminium compound if desired, in typical low-pressure polymerizations or in a high-pressure ethylene polymerization, giving finely divided polymers in either case. In the examples catalysts comprising TiCl 3 , VCl 3  or VCl 4  and Et 2 AlCl are treated with styrene, allylcyclohexane, 4-methylpentene-1 or 5-methylhexene-1, and optionally also decene-1, and then used to polymerize ethylene or propylene.

Abstract: 1296769 Rotary I.C. engines C A VARON 18 Nov 1970 54838/70 Heading F1F A rotary I. C. engine, spark or diesel, providing two firing impulses per revolution, comprises a fixed cylindrical stator 5 having an annular channel receiving a concentric cylindrical rotor 3, having diametrically opposed radially sliding vanes 17a, b, with diagonal passages 18, which transfer fluid from an outer space, formed by a recess 8 in the stator channel, to a similar inner space 9 therein, whilst the vane is being cammed radially inwards by a straight ramp 11 at the end 15 of the space 12. The vane is cammed radially outward by a similar ramp at the end 14 of the inner space, and the vane passages 18 are blanked by the rotor in all other positions. From the position of Fig. 2, mixture is drawn in at an external port 16 by the vane 17a during the first quarter revolution clockwise, whilst mixture similarly drawn in by the preceding vane 17b is compressed. The latter charge is fired at 15, Fig. 3, and, as the vane 17b is being cammed inwards by the ramp 10, the charge is transferred from the outer to the inner space 9, where, during the next quarter revolution, it expands against the vane 17b, which, at the end of the next quarter, allows it to exhaust at 14 as the vane 17b is being cammed outwards by the end ramp of the inner space 9. Each vane thus has a fine impulse at 15, making two per revolution on a four-stroke cycle.

Inventor: CHRISTOPHER WALKER BRETT
IPC: H03C3/40
Filed: 1999-06-29
Abstract: A method and apparatus for adaptively correcting D.C. offset errors imposed upon signals in a communication device. The present invention includes a feedback loop correction circuit and method for measuring and reducing D.C. offset errors imposed upon analog transmission signals by transmit digital-to-analog converters (DACs) and associated analog reconstruction filters. A digital feedback loop is used to remove the D.C. offset errors from the analog transmission signals prior to transmission. In the preferred embodiment, the digital feedback loop includes a pair of analog-to-digital converters, a digital D.C. offset correction circuit, and a pair of adders. The transmission signals are digitized, filtered, and digitally processed by the correction circuit to generate offset correction signals that are equal to the undesired D.C. offset error present in the transmission signals. The correction signals are added to the digital input baseband signals thereby removing the undesirable D.C. offset errors from the transmission signals. In one preferred embodiment, the analog-to-digital converters comprise differential comparators that generate digital signals representative of the signs of the analog transmission signals. The digital D.C. offset correction circuit processes the digital signals output by the differential comparators using a selected digital signal processing technique. In one embodiment, the offset correction circuit uses a "sign bit" digital signal processing technique whereby the sign bits generated by the differential comparators are continuously integrated. The preferred embodiment of the present invention uses an MSB technique whereby sign characteristics of both the digital baseband signals and associated transmission signals are analyzed to produce the feedback correction signals. In accordance with this technique, integrators are disposed to measure zero crossing time delays between the baseband signals and the filtered signals. The zero crossing time delays are measured by analyzing the relative signs of the baseband signals and the filtered signals. The zero crossing time delays are used in the preferred embodiment as an estimate of the D.C. offset errors present in the transmission signals.
Patent IL-103182-A (IL)
Title: Mobile communications device registration method
IPC: H04M11/00
Filed: 1992-09-16
Abstract: A distance based method for mobile station registration in a cellular communication system. The mobile station registers whenever it moves into a new cell that is greater than some predefined distance from the previous cell where it registered. Cell base stations transmit corresponding base station location information and a distance value. The mobile station receives the base station location information and computes the distance from a cell in which the mobile station last registered to the current cell in which the mobile station is present. When the computed distance is greater than the distance value associated with the registration cell the mobile station registers. Pages for the mobile station are transmitted within a group of cells within a distance of the registration cell corresponding to the registration cell transmitted distance value.
