Title: Improvements relating to the moulding of concrete pipes and the like
IPC: B28B21/24
Filed: 1934-06-04
Abstract: 439,126. Moulding or lining pipes &c. with concrete. HALKYARD, C. C., and HUME PIPE CO. (AUSTRALIA), Ltd., Kinnear House, King Street, Melbourne, Australia. June 4, 1934, No. 16607. [Class 87 (ii)] In moulding or lining pipes and the like with semi-dry concrete, the material is introduced into a mould 2, is subjected to roller pressure acting simultaneously upon the whole length of the material so as to distribute it lengthwise and circumferentially throughout the mould into a partially compacted annulus and is finally consolidated by combined concussional and centrifugal actions. The mould 2 may be supported by end rings 3 on runner wheels 4 and adapted to be rotated and jolted by means such as described in Specification 409,527. A rotary levelling and pressing member, which may be a tube 9, is supported lengthwise within the mould and spaced from the walls thereof. The tube may be rotatably supported in open-ended recesses 18 in plates 17 carried by vertically adjustable arms 13 secured to a base frame. Stop-pins 19 or collars prevent endwise movement of the tube. In operation, the mould is first rotated and contact with the material causes rotation of the tube 9. The open ends of the recesses 18 are so disposed and the rotation is in such a direction that the tube is maintained in the recesses. After distribution of the concrete by the rolling pressure, the tube 9 may be withdrawn and the mould then subjected to the concussional and centrifugal actions.

Title: Improvements in and relating to Non-Woven Web Material
IPC: D04H1/66
Filed: 1967-04-11
Abstract: 1,188,506. Laminated non-woven material. KIMBERLEY-CLARK CORP. 11 April, 1967 [28 April, 1966], No. 16622/67. Heading B5N. A non-woven web material comprising a unitary multi-component structure comprises top and bottom layers 14, 11 of cellulose wadding, i.e. so called creped tissue paper, a " highly drafted " inner layer 13, 12 of substantially aligned fibres adjacent to each of the wadding layers with the fibre direction in one fibre layer being disposed angularly to the fibre direction in the other fibre layer, adhesive being disposed in spaced pattern layers 15, 15a between each wadding layer and its adjacent fibre layer, the adhesive of each of the adhesive layers partially penetrating its adjacent wadding layer, the fibres in each of the fibre layers being partially embedded in and held by the adjacent adhesive layer, and a portion of the adhesive in each of the adhesive layers joining the adhesive in the other of the adhesive layers at regularly spaced points throughout the structure in areas where the adhesive patterns are superimposed and where adhesive extends between the fibres in each of the fibre layers. A " highly drafted " layer is one in which at least 80% of the fibres are extended to their full length in side-by-side relationship and are substantially aligned in one direction. The material may be manufactured by applying the pattern of adhesive 15 to the wadding layer 11 and joining the fibre layer thereto whilst under tension by hot calendering to form a component A. This is then joined to a component B consisting of similarly connected layers 13, 14 and adhesive 15a, by further hot calendering, which softens the adhesive and joins the patterns 15, 15a where they overlap. The wadding layers may be formed on paper making machines to have a high crepe factor which is then reduced by stretching and ironing before lamination. The wadding layers may include melamine- or urea-formaldehyde, or polyalkylene polyamide, resin to give them wet strength. The fibre layers 12, 13 may be of staple fibres or continuous synthetic filament tow and are preferably of rayon, nylon, polyesters, acrylonitriles, polyethylene or polypropylene. The adhesives may be plastisols, e.g. of vinyl chloride polymers, or copolymers of vinyl chloride with other vinyl resins plasticized by organic phthalates, sebacates, adipates, or phosphates, or may be resins per se, e.g. polyvinyl acetate, alkyl acrylate, butadiene-styrene or butadiene-acrylonitrile resins. Other patterns of adhesive than that shown are exemplified. In a second embodiment the fibre directions are mutually perpendicular and at 45 degrees to the length of the material. In other embodiments the fibre layers may comprise alternate lightweight and heavy-weight fibres or may include thermoplastic fibres. The fibre layers may be of different weights. The wadding may be made absorbent, water-resistant, fire-resistant, or vermin-resistant, and may be open or perforated, e.g. by needling, to render it porous.

Title: Improvements in or relating to telegraph receiving apparatus
IPC: H04L17/18
Filed: 1931-06-11
Abstract: 380,125. Type-printing telegraphy. CREED & CO., Ltd., Telegraph House, Croydon, Surrey.-(Teletype Corporation ; 1400, Wrightwood Avenue, Chicago, U.S.A.) June 11, 1931, No. 16982. [Class 40 (iii).] In a type-printing or like receiver (1) the armature of the receiving magnet, or a member co-operating therewith, is regularly reciprocated once per signal element so that the magnet can hold it without having to move it; and (2) a start-stop release device is so arranged that the effective portion of the signal can be selected by adjustment of the starting point. Receiver magnet with mechanically reciprocated armature. Fig. 1 shows a selector mechanism of sword-and-T type in which the sword 10 is set to one or other position by the member 29 which is pivoted at 30 and is integral with the armature 28. The receiver magnet 22 has merely to hold the armature 28 and not to move it, since during every signal element this armature is reciprocated by cam teeth 50 engaging a point 51 on the member 29. The cam teeth 50 are on the same shaft as the five cams 21 which reciprocate the sword 10 through levers 13. Modification using polarized relay. In a modification, Fig. 5 (not shown), a polarized armature separate from the part 29 acts as a. detent so that in the marking position it holds the part 29 against the spring 34, but in the spacing position not. The polarized armature cannot .pass from the free to the holding position till the part 29 has been moved to its marking position by a cam tooth 50. Start-stop release mechanism. A friction clutch, Fig. 2 (not shown), tends to rotate the cam shaft 18, but a stop-arm 66. on this shaft is engaged, in the stop position, by a gate 67 pivoted at 69 ; and the gate is prevented by a latch 70 from rotating counterclockwise under the pressure of the arm. The start signal, which is of a spacing nature, releases armature 28 and permits a head 88 carried thereby, Figs. 1 and 4, to act through a pushpin 86 and bell crank 84 to tilt the latch 70 and release the arm 68 which is integral with 67. The stop signal, which is of a marking nature, allows the latch 70 to be returned by a spring to the stop position shown, a sixth cam tooth 50 being provided for this purpose. Adjustment of effective point in received signal. The effective point in the received signals is determined by the timing of the cams 21, Fig. 1. In order that this may be adjustable, the pivot 69 and latch 70 are mounted on an adjusting plate 76 which by means of the knob can be adjusted angularly about the cam shaft 18, so that the cams 21 may start nearer to or further from their operating point 51, as required.

Abstract: 1,002,477. Calculating-apparatus. T. A. YORKSTONE. April 14, 1964 [April 30, 1963], No. 17014/63. Heading G4B. A device suitable for assisting in Boolean algebra calculations comprises a board 1 on the upper surface of which is a 32-column visual array 2, each column of which represents a possible relationship between the variables x 1 -x 5  shown at the left regarded as set functions in a Venn diagram. Thus the 32 columns of the array can be regarded as representing the numbers 0-31 in binary coded form, the individual binary digits being represented by " 0's " and "l's" (as shown) or by two contrasting colours. Arranged alongside the array is a bar carrying 32 pointers, one for each column of the array, these pointers being individually rotatable about the bar and being adjustable to positions representing " 0 " or " 1 " according as the corresponding column does not or does occur in the problem to be solved; to a position " OUT " if the corresponding column is not relevant; and to a position "#0" to cater for a " possible " occurrence of the column (i.e. a " don't care " state). As applied to simplifying a switching function of a plurality of variables, those pointers are turned to "1," which correspond to expressions occurring in the function to be simplified and by looking at those columns and picking out patterns of " 0's " and " 1's " occurring therein in a systematic manner described in the Specification, an equivalent simplified form of the switching function can be deduced.
