Patent GB-1153839-A (GB)
Title: Electrical Calculating Equipment
IPC: G06F1/02
Filed: 1968-01-12
Abstract: 1,153,839. Digital computers; function generation. INTERNATIONAL STANDARD ELECTRIC CORP. 12 Jan., 1968 [18 Jan., 1967], No. 1917/68. Heading G4A. In a system in which a digital computer generates successive digital value numbers from which a plurality of different analogue functions may be produced, each said digital value number representing the value at a defined time of one of said functions, intermediate value numbers representing a forecast of the value of at least one of said functions at a time following a said defined time are also generated to improve the accuracy with which the or each corresponding analogue function may be produced. The invention has particular application to cases in which the functions, representing solutions to differential equations, can vary rapidly with time and in which the number of functions is large, as in flight simulators, and has the effect of reducing discontinuities in the analogue outputs due to the resulting relatively long calculation cycles. The intermediate value numbers may be determined without appreciably increasing the calculation cycle time by extrapolation formulµ (e.g. Taylor's formula) or by prediction calculation (e.g. Adam's prediction formula). Linear interpolation may be combined with a predicted value to provide a plurality of intermediate value numbers. The transfer of primary and intermediate digital value numbers from the computer memory to output means including digital-to-analogue converters may be effected by a transfer device having an autonomous (wired-in) control programme and having the power to interrupt the computer when a transfer is necessary. In addition to the transfer of the intermediate value numbers during secondary cycles, some functions may have the transfer of the corresponding primary values repeated whereby the time delay before a newly calculated value is transmitted is reduced. Means are provided whereby the functions requiring intermediate value numbers may address different memory areas during each successive transfer cycle. The analogue functions may represent D.C., simple A.C. or 3-phase A.C. outputs. Detailed embodiments are described with respect to drawings (not shown).

Title: Metering ejector
IPC: B29C70/80
Filed: 1972-01-17
Abstract: 1381524 Moulding cap liners SACMI COOPERATIVA MECCANICI IMOLA 17 Jan 1972 [10 April 1971] 2072/72 Heading B5A [Also in Division B8] Plastics material for shaping into a sealing gasket of a crown cap 2 by compression or centifuging is only deposited from a nozzle 43 if a cap 2 is present on a support 3 when the support and nozzle are brought together. When a cap is present a bush 49 slideably mounted on the nozzle is pushed up against spring 50 and, via arms 52, 53 and rods 56, 14, closes a ball valve 17-22. Plastics material supplied to inlet 5 passes through apertures 16, 18 and 17 to fill ducts 9, 23 and 42a. Piston 24 is forced down against spring 41 into duct 23 and raises the pressure of the material until spring loaded valve 46 opens and material is ejected from the duct 42a and out of the nozzle 43. However, if valve 17-22 has not been closed by the presence of a cap 2 the pressure of the material is insufficient to open valve 46 and the material flows from duct 23 through valve 19 to the part of duct 9 vacated by piston 24. Piston 24 is controlled by a cam (not shown), against which a cam follower 40 runs as the device is moved about a rotating head (not shown). Upward travel of the piston is adjustably limited by extension 35 engaging stop 37. Packs of gaskets 13 and 29 in stuffing boxes around operating rods 14 and 27 are subjected only to the feed pressure and not to the ejection pressure.

Title: Process for the production of combustible gases
Inventor: PERCIVAL GEORGE
IPC: C07C4/00
Filed: 1964-01-17
Abstract: In a method of producing methane-containing gases from predominantly paraffinic hydrocarbons containing an average of from 2 to 5 carbon atoms per molecule, by passing the hydrocarbons with steam through a bed of catalyst, the temperature of the bed is maintained below 400 DEG  C., preferably between 250 DEG  and 390 DEG  C. The catalyst may comprise reduced nickel supported on alumina, e.g. the one described as catalyst E in Example I of Specification 969,637.  The bed temperature may be controlled by passing a fluid, e.g. air, or the hydrocarbon/steam feed mixture, through tubes in the catalyst, and the reaction temperature may be controlled by recirculating a portion of the product gas.  Steam in the proportion of 1.3 parts by weight to 1 of hydrocarbon average 2 to 5 carbon atoms per molecule, or 1 part by weight to 1 of hydrocarbon where the average is 2 to 4.  Two specific examples, employing commercial butane and pentane respectively, are described.

Abstract: 1,217,952. Motor vehicle anti-theft device. C. E. MARSHALL (WOLVERHAMPTON) Ltd. 15 Jan., 1969 [17 Jan., 1968], No. 2453/68. Heading B7J. [Also in Divisions E1-E2 and F1] A locking mechanism for a motor vehicle steering shaft comprises a key operable cylinder lock 23 fixed in a housing 10 attached to the steering shaft, a bolt 51 movable from a disengaged position to an engaged position with the shaft, a spring 53 biasing the bolt 51 towards its engaged position, a sleeve 36 fitted around a rotary member 29 so that when the barrel 28 of the cylinder lock 23 is operated the bolt 51 is moved to its disengaged position by the interaction of a cam formation 31 on the rotary member 29 and a stirrup (44) on the bolt 51 and a nose 43 on sleeve 36 moves to retain an abutment 67 on bolt 51 to hold the bolt 51 in the disengaged position: when the key is withdrawn a spring 61 moves the nose 43 out of retention with abutment 67 to allow movement of the bolt 51 to its engaged position. As shown, a peg 42 on rotary member 29 cooperates with a shoulder 41 on sleeve 36 so that turning of the key causes the nose 43 to be moved over the abutment 67 until a leaf spring 62 slips over the end of the sleeve 36 and is urged by a light compression spring 64 to hold the sleeve 36 in position with the bolt 51 in its disengaged position: withdrawal of the key causes disengagement of the leaf spring 62 with the end of sleeve 36. In an alternative arrangement, Fig. 5 (not shown), a resilient blade is used in place of the leaf spring. In a further alternative arrangement, Figs. 6, 7 (not shown), a lever is used in place of the leaf spring. In all these arrangements the barrel 28 of the cylinder lock 23 may be arranged to transmit drive to an operating member (not shown) of an ignition switch.

Abstract: 574,826. Paints; alkaline-earth metal plumbates. GOODLASS, WALL & LEAD INDUSTRIES, Ltd., and READ, N. J. Feb. 11, 1944, No. 2573. [Classes 1 (iii) and 95] An anti-corrosive oil paint contains, as a pigment constituent, a plumbate of an alkaline earth metal in which substantially the whole of the lead is present as lead peroxide comb ned with an alkaline earth metal oxide. The alkaline earth metal plumbate is preferably manufactured by heating in air, to a temperature of about 750‹C., an oxide of the alkaline earth, or a salt thereof such as a nitrate, a carbonate or with an oxide of lead, e.g., litharge or red lead or a salt thereof which will produce an oxide or oxides on heating. The proportions of the oxides should approximate to those required for the production of the orthoplumbate in the case of calcium and strontium plumbates but this is not necessary for the production of barium plumbates. A white calcium plumbate can be prepared either by adding to the mixture of lead and calcium oxides before furnacing, a little (0.5 to 5.0 per cent. by weight) powdered silica and heating to 700‹C., or by employing excess of calcium oxide during the heating operation. The alkaline earth metal plumbate can be employed in conjunction with other pigments, e.g., iron ox'de. Examples of the production of the plumbate and of typical paints are given.
