Title: Improvements in or relating to laminated fabric
IPC: D06Q1/02
Filed: 1941-05-09
Abstract: 549,217. Treating artificial silk; &c. compound fabrics. BRITISH CELANESE, Ltd. May 9, 1941, No. 6028. Convention date, May 10, 1940. [Class 2 (ii)] [Also in Group VIII] A fabric containing yarns. of an organic thermoplastic material is treated with a plasticizer for the thermoplastic material, aged, wetted with a liquid which is both a solvent for the plasticizer and a swelling agent for the thermoplastic material, and again aged. The treatment renders the fabric suitable for use as a laminating fabric for adhesively uniting the components of a laminated fabric. The treatment removes a substantial proportion of the superficial plasticizer from the fabric, particularly when the fabric contains non-thermoplastic yarns in association with the thermoplastic yarns and also causes the plasticizer to penetrate more deeply and in greater quantity into the thermoplastic component of the fabric. The thermoplastic yarns may be of cellulose acetate or other cellulose ester or ether or of a synthetic linear polyamide. The fabric may contain cellulose or natural silk yarns as non- thermoplastic component. It may be formed by weaving, knitting, knotting, or netting. The plasticizer may be introduced by dipping, coating, or spraying, a solution of the plasticizer in an organic solvent, preferably containing a penetrating agent, being used. Plasticizers for cellulose acetate include sulphonamides, phthalates, phosphates and tartrates. The penetrating agent may be Turkey red oil, xylene, toluene, pine oil, sulphonated pine oil, "Monopol" oil (Registered Trade Mark), cyclohexanone, diacetin, or tetrahydronaphthalene. The plasticized fabric may be aged by leaving it, in rolled form if desired, for 5-6 days at 85-160‹F. The solvent for the plasticizer may be a lower aliphatic monohydric alcohol, e.g. ethyl or methyl alcohol. In an example, a fabric containing cellulose acetate and cotton yarns is dipped into a solution of di- (methoxy-ethyl)- phthalate in ethyl alcohol and then passed through nip rollers. About 30 per cent. of plasticizer remains on the fabric. The fabric is passed through a heated chamber to remove the alcohol and is then aged in another heated chamber. It is unrolled, moistened with ethyl alcohol, dried, and aged for about one day. When using the fabric as a laminating fabric, the superposed layers of fabric are subjected to heat and pressure. The fabric may be used in the production of laminated fabric for collars.

Title: Improvements in or relating to Electric Welding Apparatus.
Inventor: WOLTMANN ERNST
IPC: B23K9/067
Filed: 1916-04-27
Abstract: 100,401. Woltmann, E. May 1, 1915, [Convention date]. Heating by electricity.-A metal electrode for are welding is moved automatically relative to the hand apparatus in which it is mounted to keep the length of the arc constant. When the operator closes the switch 41, Fig. 7, the coil 7 draws up the core 9 to balance the adjustable spring 29<a>, Fig. 8. When the arc has been struck between the pencil 27, Fig. 7, and the work 38, variations in the flow of the arc cause variations in the flow of current through the arc and coil 7, and consequent movement of the core 9 and pencil 27 to correct the length of the arc. If the apparatus is brought too close to the work, the core 9, in moving down to lengthen the arc, makes contact at 53, so that some current passes through the buzzer 50 and thus warns the operator. The buzzer 50 is preferably carried by an insulating- block 47b on the top of the coil 7, which is encased in a cylinder 1<a> by which the apparatus is held. The core 9 is connected to a graphite plunger 9<c> acting as a dash-pot. Instead of clamping the pencil 27 directly to the lever 12, Fig. 7, it may be clamped to a member 67, Fig. 8, sliding in a cylindrical part 69 of the frame 14<a> and connected to the lever 12 by a pin and slot 71. The clamp 16 is connected to the frame 14<a> by a flexible conductor 13e.

Abstract: 792,054. Apparatus for testing agility. CALDER, J. D. Feb. 29, 1956 [March 2, 1955], No. 6127/55. Class 81 (2). Apparatus for testing or improving manual or pedal agility includes a plurality of movable members arranged in a pattern, a like number of respectively associated indicators arranged in an identical pattern, the indicators to be displayed successively in a selected order, appropriate movable members on actuation by the user operating the or each displayed indicator to a cancelled condition. A platform 11 has recesses containing movable members 24-33 and is covered with sponge rubber sheeting 34. A display board includes a translucent screen 35 behind which lamps 14a-23a are arranged in a pattern corresponding to the arrangement of the movable members 24-33. Microswitches 14-23 are associated with each movable member 24-33, each microswitch being in series with a lamp 14a-23a but in parallel with the other microswitches in a circuit including a battery 41, a relay 43 and a conductive drum 46 of a selector mechanism. Each lamp 14a-23a is connected with a finger 14b-23b which can contact the drum 46 through holes 69 in a chart of insulating material stretched over the drum. The holes 69 are so arranged that two of the fingers 14b-23b contact the drum simultaneously, thus energizing two of the lamps 14a-23a simultaneously. When the movable members 24-33 appropriate to the displayed lamps 14a-23a are pressed down by the feet of the user, the corresponding microswitches 14-23 and the relay 43 are opened so that the solenoid 61 is de-energized. A pawl and ratchet mechanism controlled by the solenoid 61 is then freed to rotate the drum 46 by one step so that different lamps 14a-23a are displayed and the relay 43 and solenoid 61 are again energized. The platform may be suspended vertically on a wall and operated by punching with the hands. The indicators may be displayed singly instead of in pairs. The indicators may alternatively be annunciator flaps, bells or buzzers and the movable members may be connected to them by pneumatic, hydraulic or mechanical means.

Title: Method and apparatus for forming and trimming die castings
IPC: B22D31/00
Filed: 1947-03-04
Abstract: 622,167. Trimming die-cast articles. PLASCO, Ltd. March 4, 1947, No. 6196. Convention date. April 24, 1946. [Class 87 (ii)] [Also in Group XXII] In making trimmed die castings of metal or plastic material, a casting, consisting of an article part 18 and a guide part 20, is cast at one station "A" and falls, guided by the part 20 to a trimming station " B " where it is held with the part 18 in a predetermined position and trimmed. The closed dies 10, 10<SP>1</SP> are filled by a nozzle 58 to form the parts 18, 20 and also a holding part 22 about the end of a fixed rod 23 which holds the casting when the dies are opened as shown. A collar 27, which closes the top of the cavity 13 when the dies are closed, is then moved down to strip the casting from the rod 23 and it falls with the part 20 enclosed in a channel 37 of a guideway 29 pivoted at 41 and aligned with a fixed guideway 30. When the casting reaches station " B " as shown it is arrested by a stop 33. Tools 31, 32 then close on the article 18 which is cut from its gate 25 and forced between a trimming die 52 and punch 53 and against a spring-pressed sleeve 54 which ejects it when the tools separate. The stop 33 is then withdrawn to allow the scrap 20, 22, 25, 24, to fall out and is then repositioned.

Title: A new or improved air distributor valve assembly for controlling the supply of compressed air to air-operated equipment, such as air-operated vehicle brakes, to cause the latter to be operated progressively
IPC: B60T13/58
Filed: 1953-06-30
Abstract: 797,802. Fluid pressure vehicle brakes. HANDS, P. J. Sept. 17, 1954 [June 30, 1953], No. 6292/58. Divided out of 797,801. Class 103 (1). An air distributer valve assembly which is mounted on the dolly or trailer of a tractortrailer unit of the type described in Specification 797,801 comprises a solenoid 94 which is energized by closure of contact 97 on initial application of the brakes. Energization of solenoid 94 causes an inlet valve 48 to be opened and air passes from port 45 to chamber 47. Air from chamber 47 passes on the one hand by passage 62 to the right-hand end of a transfer slide valve 49 which is moved to the left so that the groove 54 puts a passage 67 leading to a chamber 80 surrounding a cylinder 76 into communication with a passage 64 leading to a combined filter and non- return valve 68 in communication with chamber 47 by passage 69. The filter and non-return valve 68 is connected through a restriction port 73 with the left-hand end of piston valve 75 in cylinder 76. Thus, when the inlet valve 48 is opened, air passing at reduced pressure from the jet 71 acts upon the piston 75 and passes by way of passages 61 and 60 to the brake cylinders, also at a reduced pressure, for example 48 pounds per square inch, depending on the size of the jet 71. Subsequently the piston 75 is moved against the spring 78 to the right, the movement being damped by the effect of fluid on the right of the piston, which can only escape through a jet orifice 83. As piston 75 moves to the right it uncovers ports 81 in the liner 79 and allows air at a pressure of 80 pounds per square inch to pass from chamber 80 through passage 61 and outlet 60 to apply the brakes with increased force. In the event of an emergency brake application, such that the pedal 165 closes contact 98, the solenoid 95 is energized and valve 93 is opened so that fluid pressure on the right of piston 75 is released and, as there is no damping effect, the piston 75 is moved rapidly to the right.
