Title: Improvements relating to the use of hand-composed matrices in typographical line-casting machines
IPC: B41B11/00
Filed: 1934-11-08
Abstract: 447,061. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., 9, Kingsway, and AYNGE, W. E., Glyneva,Sydenham Park Road, Upper Sydenham, both in London. Nov. 8, 1934, No. 32111. [Class 100 (iii)] Assembling matrices.-A, hand composing- stick is adapted for the insertion of a line of hand-composed matrices into the assembler elevator, so as to be controlled by the normal operations of the machine. The stick comprises a flanged matrix-supporting shelf 1, Figs. 1 and 2, on which the matrices are assembled between a clamping-abutment 2 and an abutment 3, which is adjustable by means of a catch engaging in notches in the flange 5 of the shelf. The abutment 2 is carried by a slide 11, and is movable inwards in order to clamp the line. A lug 12 on the slide 11 co-operates with a fixed lug 14 to form a finger-and-thumb grip, by means of which the stick may be handled and the line clamped and released. The lugs 12, 14 are separated by a spring 16, which normally holds the abutment 2 in the outer position. When a line has been assembled, the stick is inverted and placed against the assembler, the hinged front gate of which is lowered. The clamping-abutment 2 is then released, and the matrices are permitted to fall into the assembler. After the casting, the line is restored to the stick from the second elevator, which is arrested in an intermediate position. In a modification, adapted for use with lines containing spacebands, a slightly narrower shelf 33, Fig. 6, is spring-supported over the shelf 1, so as to form a gap 39 between it and the flange 5, in which the ears of the spacebands are accommodated. Pressure of the stick against the assembler depresses the shelf 33, so that the spacebands are released.

Filed: 1923-12-22
Abstract: 219,581. Vereinigte Gummiband- Webereien Tillmanns, Schniewind, & Schmidt, and Schwabe, M. Dec. 22, 1923. Fashioned fabrics, looms specially designed for; take-up motions.-In looms in which the width of the fabric is varied by spreading the warps apart and in which the take-up is regulated to maintain the fabric at a uniform thickness by a corresponding crowding of the weft threads, a cam-operated lever t controls the position of swallow-tailed reeds in the lay k and regulates the stroke of a bell-crank lever 6 which actuates the take-up motion. The warps are spread by a rising and falling beam e connected by cords n, u and a lever t. The cam r is operated through ratchet and toothed gearing by a cord connection 2 to the lay. The take-up lever 6 is rocked by a cord connection 7 to the lay, its downward motion being limited by an adjustable rod 5 carried on the lever t. The position of the lever t thus determines the width of the fabric and the spacing of the weft threads.

Abstract: 778,685. Aerofoils. BRISTOL AIRCRAFT, Ltd. Feb. 16, 1955 [Nov. 20, 1953], No. 32240/53. Class 4. [Also in Group V] A cellular aerofoil or component part thereof consists of a onepiece moulding comprising at least one skin layer 34 with its surface formed to the aerofoil contour, at least one other layer 35 substantially co-extensive with the first and spaced therefrom over at least part of its area, each layer being composed of fibrous material bonded with thermoset resin and/or of metal, and a plurality of spanwise extending webs made of fibrous material bonded with thermoset resin, and presenting with the layers in chordwise section a substantially fully triangulated structure, the triangular cells in which can each be filled without distortion of the structure by a rigid core insertable into or withdrawable from the cell in a spanwise direction. In the all-moving tail plane described, of thin parallelogram crosssection, a further core is inserted part way into the moulding to form a socket with walls 38 for a mounting shaft 30. A further core leaves an aperture for receiving a rib 31 fast to the shaft to take up torque. In the case of a tapered wing, the outermost triangular cells end short of the tip. The layer 35 ends somewhat short in the chordwise direction of layer 34, and the surface is completed by leading and trailing portions 36 of resin bonded fibrous material. Phenolformaldehyde or polyester resins may be used. In manufacture, a two or more part mould is charged with the layers 34 and 35 and with triangular cores wrapped with fibrous material impregnated with uncured or partly cured thermosetting or hot setting resin. Any remaining space is filled with impregnated fibrous material, to a volume greater than that of the mould, so that when the mould parts are together, the charge is compressed. It is then heat cured. Alternatively, the charge may be of less volume than the mould, and after closing the mould, a liquid mixture comprising uncured or partly cured thermosetting resin is injected into the mould to a required moulding pressure. The mould may be raised to the curing temperature immediately before, during or after injection. Specifications 778,681 and 778,683 [Group V] are referred to.

Title: Improvements in power-driven ciphering devices
IPC: G09C1/12
Filed: 1952-12-22
Abstract: 722,589. Ciphering apparatus. HAGELIN, B. C. W. Dec. 22, 1952 [Jan. 23, 1952], No. 32456/52. Class 146 (2). A power driven ciphering machine comprises type wheels 40 which are set into a primary position by the operation of a key 20 on a keyboard and then reset to a secondary position by a step-by-step driving mechanism 39. The type wheels 40 are rotated through type wheel shaft 101, gearing 5, and a clutch 4 from a continuous drive 1-2 and are arrested in the primary position by an electrical control locking the driving shaft 101 of the type wheels 40. The locking of the shaft 101 in the primary position is effected by a ratchet 98 and a pawl 24 on the arm 15 of an armature 14 actuated by an electromagnet 17. This magnet is normally operative by a circuit comprising a battery 38, cam contacts 37, and by a circuit extending through a slip ring 97 and commutator 94, wires 68-93, an interchangeable coding switch 41 and contacts 18 on a key 20. When a key 20 is depressed, a lever 21 is pivoted moving a bar 10 which engages behind a pawl and releases a ratchet wheel 7 so that the continuous drive is transmitted through the slipping clutch 4 to the shaft 101. When the desired primary position of the type-wheels is reached the commutator 94 is connected to contacts 18 which have been opened by the depression of a key. The circuit to the magnet is thus broken and arm 15 causes the pawl 24 to engage the ratchet 98 and to lock the shaft 101. At the same time a pawl 25 disengages from a disc 26 on a shaft 100 which transmits rotation from the drive 1 through a clutch 3 to the step-bystep mechanism 39. This imparts, via gearing 96,. a number of ciphering steps to the shaft 101. The type wheels 40 have two axial positions so that printing may occur after their primary position as well as after the operation of the step-by-step driving mechanism. A cam 27 restores the arm 15 and disconnects the pawl 24 from the locking ratchet 98, and a cam 28 restores the bar 10 to release the key-lever 20.

Abstract: 1,262,472. Making sandwich biscuits. UNITED BISCUITS Ltd. 4 July, 1969 [8 July, 1968], No. 32471/68. Heading A2A. [Also in Division B8] In apparatus for making sandwich biscuits, a single row of biscuit layers, which is fed along a channel 13 by fingers 26 projecting through a slot in the channel and carried by an endless chain, travel beneath a creaming head 32 which is arranged to cream alternate biscuit layers, after which the uncoated layers are lifted by a cam-operated pivoted flap 9 to clear the associated fingers so that they are each abutted by a following creamed layer, the pairs of biscuit layers thus produced then passing to a mechanical handling device consisting of a depending finger 30 which engages the uncreamed layer of each pair, causing it to ride up the inclined surface of the finger and, during continued movement of the endless chain, be tipped over backwardly on top of the preceding creamed layer. A depending flap 11 contacts the completed biscuits to accurately align the superposed biscuit layers, after which the biscuits pass through a tunnel where the top layers are engaged by a presser 12 to compress the biscuits, prior to discharge to a delivery conveyer 25. The tipping finger 30 includes a rearwardly bent lower portion which acts as a ramp up which the uncoated biscuit layers slide, and is provided with an abutment which engages the forward edge of the uncoated layers to assist the tipping action. The creaming head 32 is fed by a chamber containing two slide valves 39, 40 which are operated simultaneously by cam discs 44 so that when flow valve 38 opens by-pass valve 37 closes and vice-versa, so that a continuous flow of cream at constant pressure may be maintained. Further cam discs 50 operate a piston 47 working in a port 45 communicating with the creaming head outlet, the operation of the piston creating a vacuum in the outlet at the time the flow valve 38 closes, to ensure quick cut-off of flow, and creating an overpressure in the outlet at the time the flow valve 38 opens, to ensure quick commencement of flow.
