Abstract: 1,031,302. Aluminium and boron citronellyl oxides; tricitronellyl aluminium. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Sept. 29, 1964 [Feb. 7, 1964; June 10, 1964], Nos. 5256/64 and 34090/64. Addition to 993,666. Headings C2C and C2J. Aluminium and boron tricitronellyl oxides are prepared by treating the tricitronellyl of aluminium or boron with molecular oxygen in the presence of a zinc or cadmium compound as oxidation promoter during at least the latter part of the oxidation, the oxidation being carried out at a temperature below 30‹ C. The citronellyl oxides may be hydrolysed to form citronellol (3,7-dimethyl oct-6- enol). The zinc or cadmium compound used may be one containing the group -OR, in which R is any hydrocarbon radical. It may be added in the form of zinc or cadmium hydrocarbyl which is oxidized to the desired compound in situ. Suitable compounds of zinc and cadmium are, e.g. zinc diethyl, zinc-di-npropyl, zinc - diisopropoxide, zinc - diisobutyl, zinc diethoxide, zinc dioctoxide, zinc stearate, zinc 3,5-diisopropyl salicylate and cadmium diethoxide. The compounds may be found in situ from, e.g. zinc oxide or zinc chloride. If desired, a solvent, e.g. benzene or toluene, may be present in the reaction mixture. The oxidation promoter is used generally in an amount of 0À5-30% by weight based on the weight of aluminium. The citronellyl oxides may be hydrolysed to citronellol by heating under reflux with water or by heating with an aqueous solution of a mineral acid, e.g. sulphuric acid. The aluminium tricitronellyl used as starting material may be prepared by reacting an aluminium trialkyl in which each alkyl group contains less than 10 carbon atoms with 2,6- dimethyl-2,7-octadiene.

Abstract: 1,226,123. Spray producers. WALTER C. BEARD Inc. 3 April, 1968 [7 April, 1967], No. 15992/68. Heading B2F. [Also in Division F1] A fluid dispensing valve structure for a pressurized container comprises a shell adapted to be positioned and retained by a resilient member at an opening of the container and to be pivotally movable, and a plug movable within the shell and forming a seal internally of the shell for an outlet orifice of the shell, the arrangement being such that upon pivoting of the shell within the resilient member, the shell acts upon the plug to cause it to pivot away from the orifice to permit discharge of fluid from the orifice. A cap 13, Fig. 3, secured to the container top 11 by a rolled-over rim 14 and a gasket 15 carries a resilient seal 19 within which a shell 20 is located in a normally upright position. The shell and cap are of metal or rigid plastics material. A plug 24 which is slidable within the shell 20 normally engages a seal ring 23 to close the discharge orifice 21. For ease of cleaning, the tip of the plug may extend into or through the discharge orifice. When the shell 20 is tilted, as shown, a flange 28 entsh shrd etao shrd etao shrd etaoi shrd eta dl gages the conical or flared side wall 16 of the cap 13 and slides along the side wall to open the valve. Fluid then passes into the hollow plug 24 at 27 and out of it at 26 (or passes around the plug if it is not hollow) and is discharged through the orifice 21. The plug may be solid, with the tip (or all the plug except the flange) of rubber or of flexible plastics, and the seal ring 23 may then be omitted. In another embodiment, Fig. 9, the cap 51 projects into the container 50, relative movement between the plug 58 and the shell 54 being effected by engagement of a flange 61 with the preferably flat base 52 of the cap. As shown, the resilient seal 53 in which the shell 54 is seated may be extended under the base 52 for engagement by the flange 61. In Fig. 12, the container 80 is formed to support a member 81 which supports or locates resilient seal rings 83, 85 and a rigid ring 84 of metal, plastics or hard rubber. Flanges 87, 89 of the shell 86 and plug 88 are located between the rings as shown. Fig. 13 shows a modification which may be applied to any of the preceding embodiments to ensure closure of the valve, comprising a compression spring or, as shown, a slug 108 of rubber or the like which is seated between the plug 101 and a support member 105. Fig. 17 shows a modification for effecting break-up of the fluid, comprising straight or helical channels 114 formed in the plug 112. Channels which may be disposed at an angle to impart swirl may instead be formed in the resilient seal 113.

Abstract: 1,227,887. Anhydrides of polycarboxylic acids. LUWA A.G. 9 Dec., 1968 [13 Dec., 1967], No. 58436/68. Heading C2C. , A method for the continuous production of an anhydride from a polycarboxylic acid comprises, as a first stage, subjecting a dilute solution of the acid to concentration by thin film evaporation of water therefrom, as a second stage,subjecting the concentrated acid, substantially without cooling, to thin film heat treatment to effect dehydration thereof and, as a third stage, effected prior to any partial condensation, rectifying the vaporous anhydride to separate the anhydrate from any impurities present therein. The example prepares maleic anhydride in an apparatus in which: pressure control means are placed between the first and second stages to allow of different pressures being used in each; the impurities from the third stage are recycled to the second; and the rectified anhydride is condensed in a triple condenser system, pure anhydride being drawn off from the first condenser and water/anhydride mixture from the second which is recycled to the process, while in the third condenser any remaining anhydride is washed out of the gases and the resulting highly dilute maleic acid recycled if desired. Reference is also made to dehydrating citraconic and phthalic acids. The process may be operated under reduced, normal or elvated pressures.

Abstract: 1,229,183. Digital computers. INTERNATIONAL STANDARD ELECTRIC CORP. 23 July, 1969 [1 Aug., 1968; 2 Aug., 1968], No. 36986/69. Heading G4A. A slice of a data word is designated by an address comprising a first portion BT to indicate the location of the first bit of the slice within its word and a second portion LG to indicate the number of bits which form the slice. An operation can be carried out on two equal length slices of two separate words by first moving one of the slices to a predetermined position in a store using a one operand instruction, thus shortening the subsequent two operand instruction since the position of the one slice does not need specification. The result is also so positioned and can be used for a further calculation. Positioning is carried out by rotation or shifting. In Fig. 5 a digital computer, for example for telephone or telegraph exchanges, comprises a processor OP, a memory ME, control circuits COM, and registers RM, RN, RX. To perform a two oper- and add instruction, one operand instruction is first read out from memory ME and sent to circuits COM via register RN. The circuits COM calculate the data word address, send the word from the memory ME to register RM and add it in processor OP to register RX (holding zero) where it is stored. Thus a processor OP has an input mask (referred to as the further selection means) so register RX holds the designated slice; which is also moved to the right (justified). The next (two operand) instruction is processed in the same way and a data slice added to that in register RX using the processor OP. Masking circuitry.-The processor OP has sixteen logic circuits (EPO to EPIS, Fig. 6, not shown), one for each word bit. Each circuit receives signals which set a mask bit, thus only the designated slice of a word is passed through. A circuit (CD) interprets portions BT, LG from circuits COM and provides the signals. The processor also aligns the slices for addition &c. An output mask may also be provided. In Fig. 1 the data word is of 16 bits so BT and LG require four bits each in an instruction word to define them in binary code. By using an octal notation (Figs. 13, 14, not shown) the number of bits required to specify BT and LG is reduced from eight to seven. Word processing is in parallel.

Abstract: 1,229,714. Extruding foam filled sections. S. A. M. AHLQVIST. 13 Nov., 1969 [14 Nov., 1968], No. 55735/69. Heading B5A. [Also in Division F2]  A method of manufacturing a tube comprises producing a one-piece wall element containing a tube part 10 and a fastening part 11, the fastening part having a contour which corresponds to that of at least one portion of tube part 10, introducing foamable plastics material into tube part 10, winding the wall element helically, making a joint between adjacent turns of the wall element, and allowing the cellular plastics material to set. In a preferred embodiment the wall element is extruded from plastics material through extruder head 41 (Fig. 4, not shown), and the foamable plastics material is introduced into tube part 10 through a feeding tube (42) as the wall element emerges from the extrusion head. If the foamable plastics material is a thermosetting resin, e.g. a phenolic resin, the wall element is helically wound immediately after the cellular material is introduced. If a thermoplastic material such as foamable polyethylene containing a blowing agent is used, the wall element is heated after the wall element has been helically wound, so as to vaporize the blowing agent. Alternatively a mixture may be inserted which reacts in situ to produce a polyurethane foam with an optional integral skin. The helical joint between fastening part 11 and the left hand lower portion of tube part 10 may be made by means of adhesive, or by passing the interconnected wall elements between heating elements to produce a welded joint.

[Also in Division A4] A control circuit for self-parking vehicle windscreen wipers, with provision for an adjustable delay between successive wipes, comprises NPN transistors 25, 28, which are alternately conducting for charging capacitors 30, 27, and controlling an NPN transistor 22 for deenergizing and energizing a relay coil 18 controlling a contact 17 in the circuit of the wiper motor 12, increase in the value of a variable resistor 31 increasing the delay between successive cycles of wipes. When transistor 28 is on, then transistor 25 is off and transistor 22 is on so that coil 18 is energized and contact 17 completes an earth circuit for motor 12, so that the motor operates. Capacitor 27 charges through resistor 26 and transistor 28, and when it is charged transistor 25 turns on, and then transistor 28 turns off. Then transistor 22 is turned off, so coil 18 is de-energized and contact 17 breaks the earth circuit by way of a contact 15, although the wiper motor continues to operate by virtue of an alternative connection through a limit switch (not shown) until the wipers reach their parked position. When transistor 25 is on, capacitor 30 charges in a time settable by resistor 31 until transistor 28 conducts, &c. Ganged switches 14, 15 give "off", "continuous on" and "intermittent on" positions for the wipers. The contacts are on a printed circuit board also carrying resistor 31 and capacitors 27, 30. The other components between lines 16, 21, are in the form of a thick film circuit also mounted on the printed circuit board (except for coil 18).
