Title: Improvements in and relating to the manufacture of lace on lace curtain machines
IPC: D04C5/02
Filed: 1927-05-13
Abstract: 294,314. Borland, G., and Muir, H. M. May 13,1927. Lace.-Relates to the production on curtain machines of filet net or other lace with coloured pattern effects or designs clothed therein. Two fully-threaded guide bars d<1>, e<1> containing coloured threads d, e are located behind the filet net and the warp bars c<1>, a'. The threads d, e are placed only where they are required to form the pattern, the remaining spaces being filled with white or coloured threads k. The threads d, e are caused to cloth or to float as required by jacquard selection of the corresponding jacks i which act at each half motion between the first and second movements of the guide bars d<1>, e<1>. The bars a<1>, c<1> are operated as usual. The cards are so punched as to cause the threads e to pillar at the places where the threads d form a pattern but where the threads e form a pattern, the threads d may float or may be tied in as shown at l, m. Where neither thread forms a pattern both float as shown at d<2>, e<2>. These floats are subsequently removed. Methods of drafting the point paper from which the cards are prepared by the use of several colours are described. In modified methods of working each thread may be caused to float when not forming a pattern but the bars d<1>, e' require to be on the outside of the bars a<1>, c<1> and the floats lie on both sides of the lace. The patterned areas made from the threads d, e may coincide.

Filed: 1960-04-13
Abstract: 997,854. Actuation of switches. AUTOMATIC ELECTRICAL CONTROL CO. Ltd. July 13, 1961 [April 13, 1960], No. 13120/60. Heading H2B. Two switches operated selectively according to the direction of rotation of a shaft 6 are mounted as shown on a base plate 1 such that their operating members 16, 19 extend respectively into the path of travel of insulating members 10 depending from the outer race 7b of a grease-packed ball or equivalnt bearing, the inner race of which is fast upon the shaft 6a. When the shaft 6a is stationary, contacts on pivoted members 16 and 19 are spring- urged against contacts on resilient blades 14a and 17 respectively, as shown. When shaft 6a rotates frictional drag on the bearing race 7b causes the appropriate member 10 to move the associated switch-operating member 16 or 19 and break the circuit with blade 14a or 17. As the speed of shaft 6a increases contact is made with resilient blade 14 or 17a. Straps 11 carry bolts 12 to act as stops preventing excessive strain on the switches at higher speeds of shaft 6a.

Title: Improvements in aircraft brakes
IPC: B64C25/48
Filed: 1933-05-10
Abstract: 416,440. Aircraft wheel - brakes. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, GOODYEAR, E. F., WRIGHT, J., and TREVASKIS, H. W., c/o Dunlop Rubber Co., Foleshill, Coventry. May 10, 1933, No. 13564. [Class 4.] A hydraulic brake system particularly for aircraft comprises a pair of cylinders forming part of a casing and connected each to a brake operating device and a third cylinder, the piston of which is operated by fluid-pressure controlled by the operator and which operates the pistons of the first mentioned cylinders through a member which can move both longitudinally and angularly within the casing so as to move the two pistons equal or unequal amounts. As applied to an aeroplane, the apparatus is used for applying brakes on the two sides of the machine differentially for steering. Cylinders 2, 3 forming part of a casing 1 are connected by pipes 18, 19 respectively to wheel brakes on the two sides of an aeroplane. The pistons 8 have apertures 9 adapted to be closed by the spherical ends of the piston rods 13 which are connected at 16 to a triangular member 17 connected also by a pin 34 to the piston rod 33 of a piston 31 sliding in the cylinder 4. A pin 43 on the member 17 slides in a slot in a fixed member 44, the slot lying in the axis of symmetry CC of the apparatus and the pin 34 slides in a slot 35 in a member 36 secured to a shaft 37 pivoted to the casing 1. The shaft 37 is connected to the rudder bar. The cylinder 4 may be connected by pipe 28 to a single-stroke hand pump or master-cylinder the piston of which has an aperture through it closeable by the piston rod similar to those in the pistons 8. The handle of this pump may be held in operative position by a detent device. The cylinder 4 may however be connected to an air pump or to a supply of compressed air. In the retracted position, the pistons 8 abut on adjustable stops 20 and the ends 15 of the piston rods are withdrawn from the apertures 9 so that liquid which fills the casing is in free communication with that in the outer part of the cylinders. If pressure fluid is supplied to the cylinder 4 with the rudder bar and member 36 in the normal position shown, the member 17 guided by the pins 43, 34 moves longitudinally and imparts equal movement to the pistons 8 so that the two brakes are applied equally. If then it is desired to make a turn, the member 36 is swung about its pivot 37 so that the member 17 is swung about one of the pivots 16, one of the pistons thus being withdrawn to relieve the pressure on one of the brakes without substantially increasing the pressure on the other brake. A collapsable reservoir 61, Fig. 4, of flexible material in a detachable casing 58 is connected to the casing 1 and to the handpump to maintain the liquid supply therein and to compensate for the increased effective volume of the casing when the pistons 8 are moved outwardly in the application of the brakes. Specification 379,529, [Group XXXIV], is referred to.

Title: Improvements in or relating to crepe fabrics
IPC: D06Q1/02
Filed: 1934-05-05
Abstract: Figured effects are produced on cr<\>zepe fabrics containing overtwisted threads and threads capable of parchmentization by local treatment with swelling agents having a parchmentizing action on the treated parts followed by the usual processing treatments.  The fabric may be treated, after reserving the parts it is not desired to parchmentize, either before the shrinking of the fabric to produce the cr<\>zepe effect or after such shrinking, the parchmentizing treatment being effected while the fabric is under tension.  The parchmentizing agents may be such as concentrated inorganic acids, or cellulose dissolving salts, sulphuric acid, e.g. of 50 DEG  B<\>ae. being preferably employed.  The materials treated may be of vegetable fibres, regenerated cellulose or animal fibres.  Colour effects are produced on dyeing the fabrics owing to the special affinity of the parchmentized portions for dyes.  Dyes which become fixed in the fabric may be incorporated with the reserve in the reserving process and colour-discharge effects may be produced on previously dyed fabrics by adding colour-discharging substances to the reserve.

Title: Improvements in typographic composing machines
Inventor: LAWLESS ALBERT
IPC: B41B11/38
Filed: 1961-04-17
Abstract: 953,367. Type-bar-making machines. LINOTYPE & MACHINERY Ltd. April 17, 1962 [April 17, 1961], No. 13758/61. Heading B6W. Clamping matrices; metal pumps.-A vice jaw 1 for a line-casting machine is composed of two portions 2, 3, one portion being capable of sliding relatively to the other and being resiliently urged in the direction of an assembled line of matrices and spacebands 9 and the other vice jaw 53. The jaw portion 3 has a shank 6 slidable in a slot 5 in the jaw portion 2 and having a spindle mounted on its rear end, the spindle being surrounded by a spring 12 and slidable in a hole in the jaw portion 2. The spindle is used to close a microswitch 16 actuating a short line casting prevention device. A pin and slot connection (not shown) between the two jaw portions limits relative movement between the two. If an assembled line of matrices is too short the jaw portion 3 is not pushed far enough back in relation to the portion 2 during justification of the line for the spindle carried thereby to close the microswitch 16, in which case a solenoid-operated latch prevents actuation of the metal pot pump. When a casting action has taken place the assembled line of matrices is lifted from between the vice jaws by the first elevator 22 and the resilient mounting of the jaw portion 3 ensures that as the jaws release their locking action on the matrices a resilient pressure is maintained on the line which results in a wiping action between the jaw faces and the end matrices as the latter are lifted. Quadding and centring are effected by known means including a quadding cam 40, a vice jaw control rod 47 and a segmental collar 50 on the rod 47, the rotational position of the rod being adjustable by a lever 51 and determining whether the vice jaws move to produce left or right quadding, centring or normal justified lines of a set length. The lever 51 is fixed to a shaft 52 which, in addition to carrying means for rotating the rod 47, carries a cam. When the lever 51 and shaft 52 are set to allow casting of normal lines the cam pivots a latch member out of the path of an abutment on a justification bar 73 which is thus allowed to rise, under spring action, at the appropriate times to effect justification of the assembled line of matrices. In all other positions of the lever 51 the latch member prevents the justification bar from rising. The cam 40 is generally thistleshaped, but the profile is modified slightly as shown at 80 so that at the completion of a quadding or centring casting operation, i.e. when a cam follower 41 has passed over a portion 77 of the cam 40, the vice jaws 1, 53, instead of relaxing their support of a line of assembled matrices in preparation for the removal thereof by the first elevator, maintains a pressure, by means of the spring 12, on the matrices as the follower 41 rides up the cam portion 80. The pressure thus imparted by the quadding cam is resiliently applied to the line of matrices through the spring loaded vice jaw.
