Title: Improvements in the treatment of cellulose triacetate fibres
Inventor: GINNS SAMUEL NELSON BRADSHAW P
IPC: D06M13/432
Filed: 1959-09-25
Abstract: The lustre of cellulose triacetate fibres is reduced by heating them to a temperature of at least 165 DEG C. while they carry urea. The fibres, which may be in the form of staple fibres or continuous filament yarn or woven or knitted fabrics consisting wholly of cellulose triacetate fibres or mixtures thereof with cotton, regenerated cellulose or synthetic polymer fibres, are preferably treated with an aqueous solution containing 20%-55% by weight of urea, based on the urea and water together, dried, e.g. on heated cans or on a stenter, and then heated to a temperature of at least 165 DEG C., e.g. 175 DEG C.-190 DEG C., for 30 seconds to 3 minutes in a stenter or baking oven.  The solution of urea may be thickened with sodium alginate, gum tragacanth or another water-soluble gum, and may also contain 1%-5%, based on the weight of the urea, of phenol or a cellulose acetate disperse dye. The urea solution may be applied locally to fabrics to obtain patterns of reduced lustre on a lustrous ground, e.g. by conventional roller or screen printing operations.  After heating the fibres may be washed to remove urea and any thickening or other agents which have been applied. Specifications 309,194, 345,673, 358,574, 747,622 and 789,243 are referred to.

Title: Improvements in or relating to pendulum weighing scales with optical transmission ofthe indicator result
IPC: G01G23/32
Filed: 1935-11-27
Abstract: 446,632. Weighing-apparatus. LEWIN, F., Station Street Buildings, Huddersneld.- (Schenck Eisengiesserei und Maschinenfabrik Darmstadt, C. ; 55, Landwehrstrasse, Darmstadt, Germany) Nov. 27, 1935, No. 32823. [Class 143] Relates to a pendulum weighing-scale wherein the indication is effected by projecting an enlarged image of a stationary graduated scale on to a ground glass screen and consists in arranging the light source in a stationary position on or in the vicinity of the knife-edge axis of the pendulum lever. As shown in Fig. 2, the load-counterbalancing pendulum, mounted on knife-edges 3, carries an optical system 7, 8, 9, 11, 12, 13 which projects an enlarged image of graduations carried on a fixed chart 17, on to a ground glass screen 14. A lamp 15 on the stationary part of the scale is arranged on or in the vicinity of the line of the knife-edges 3 to provide the illuminant. A pointer attached to the pendulum or to the casing provides the usual reading index on the screen. In a modification, Fig. 3, for dealing with tare, gross and nett weights, duplicate charts 17<1>, 19<1> are provided, one chart being a little higher than the other. The screen 14<1> is mounted on the pendulum. The chart 19<1> is movable endways so that after weighing the tare, the movable chart 19<1> may be adjusted to bring its zero to the tare indication mark and thereafter when the gross load is applied, the chart 19<1> will indicate the nett weight and the chart 17<1> the gross weight. In a modification, by graduating the charts 171, 191 in reverse directions, the nett weight may be indicated by first ascertaining the gross weight and then the tare weight. In a further modification, Fig. 4 (not shown), the mirror 9<1>, Fig. 3, lense 11<1>, mirror 121 and screen 14<1> are duplicated and each duplication co-operates with a separate pencil of light from the lenses 6<1>, 7<1>. The charts 17<1>, 19<1> may then be arranged one above the other or side by side. In a further modification, Fig. 5, the movable chart is adjusted automatically when the tare is placed on the scale. Light from the stationary lamp 37 passes through the lenses 35, 36 and is divided at the mirrors 38, 39 and projected through the charts 53, 58 on to reading screens 43, 44. The chart 58 is carried by an auxiliary pendulum 54 which is operated in unison with the load counterbalancing pendulum 30 through a whippletree arrangement connected to the load. The auxiliary pendulum may be locked by grippers 59. Before applying the load the grippers are unlocked. When the load is applied, both pendulums move accordingly and the load is indicated on both charts 43, 44. The auxiliary pendulum is now locked and the additional load imposed. The gross weight is now indicated on the screen 43.

Title: Tool carriage feeding and positioning mechanism for lathes and other machine tools
Inventor: CAFOLLA CONSTANTINE FRANCIS
IPC: B23Q5/40
Filed: 1957-10-22
Abstract: 828,280. Lathes; machine-tool details. SENECA FALLS MACHINE CO. Oct. 22, 1957, No. 32956/57. Class 83 (3). A lathe or other machine tool with a sliding tool carriage and a normally stationary lead screw, has a brake connected to the latter and a rotatable lead screw nut, the lead screw being rotated to increase the rate of traverse. A tool carriage 10 carries a rotatable nut 11 engaging a lead screw 12. The nut may be rotated by a gear 15 and splined shaft 16. The lead screw is normally held stationary by a magnetic brake 14, but may be rotated to give the carriage a rapid traverse, generally in the return movement. The shaft 16 is connected to the lead screw 12 through a sprocket drive 20-22 and through a magnetic friction clutch 23. When this clutch is closed, the brake 14 is automatically opened. The drive is provided from a continuously rotated low-speed shaft 30 and a continuously rotated high-speed shaft 31. The first is connected through pick-off gears 35, 36, to one part 32 of a two-part shaft 32, 33 connected by an overrunning clutch 37. The shaft 31 drives an aligned shaft 31a through a magnetic clutch 40 and thence through gears 41, 42 to shaft 33. The latter drives a countershaft 34 through gears 44, 45, and the countershaft has a forward drive connection to the splined shaft 16 through a magnetic clutch 50 and gears 51, 52. The countershaft also has a reverse connection to the shaft 16 through a magnetic clutch 55 and sprocket drive 56-58. A magnetic brake 25 is provided on the shaft 16 which, when operated with clutch 50 or 55 disengaged stops the carriage feed. An alternative arrangement omits the brake 25 and enables clutch 23 to be supplied with a lowvoltage so that it may slip and provide a decelerating effect on the carriage movement. Specification 724,815 is referred to.

Title: An automatic paper register and lay device
IPC: B41F1/28
Filed: 1936-12-02
Abstract: 485,945. Feeding sheets. DAVIS, S. Dec. 2, 1936, Nos. 33054/36 and 10365/37. [Class 100 (i)] A sheet-registering device for platen printing- machines is constructed with a small roller 5 which is mounted in a spring arm 4 or 41 in such a manner that it is free to rotate in one direction as the arm moves across the sheet, but is held when the arm moves in the reverse direction and so acts frictionally upon a sheet and drags it against the registering stops. The arm 4 is mounted on a registering member 3 which is secured by a screw to the desired screwed aperture in a bar 10 mounted so as to be capable of sliding in a hollow frisket shaft 2 which carries the frisket fingers 1. The bar 10 is normally pressed outwards by a spring 7, but in the normal operation of the platen the bar 10 engages a fixed cam and is moved inwards to cause the roller 5 to move freely over the sheet, and then is released from the cam and returns to normal position causing the immovable roller to drag the sheet with it. Toggle mechanism may replace the cam, and a fixed rubber pad may be used in place of the roller 5.

Title: Apparatus for conveying gases or liquids
IPC: F04B43/14
Filed: 1954-11-15
Abstract: 782,105. Rotary pumps. SCHAURTE, P. Nov. 15, 1954 [Nov. 16, 1953], No. 33069/54. Class 110 (2). A rotary pump for conveying liquids and gases by compression of a flexible diaphragm has a housing 1 in which is formed an annular groove 2 covered by the diaphragm 4. The groove 2 in cross-section has an arc-shaped central part joining two outer curved portions at points of inflexion, the radius of the central arc being equal to or less than the combined thickness of the diaphragm and the radius of balls 3 mounted for travel along the groove in a cage 5. A disc 6 connected by a driving pin 8 to a rotatable shaft 7 bears against the balls 3 to cause rotation of the balls and the cage. Spring means 10 bearing against a disc 11 holds the disc 6 in contact with the balls and to prevent slip between the balls and the disc, the contacting surface of the disc is preferably covered with material similar to the diaphragm 4. The disc 11 is rotatably mounted in the housing cover 12 by means of a bearing 13 through which passes the shaft 7 mounted in bearings 14 and 15, protected by caps 16, 16<SP>1</SP> respectively. A lug 21 depending from the diaphragm separates the inlet 24 from the outlet 25, the inlet and outlet communicating with channels 26, 27 respectively leading from the groove 2. Sockets at the outer ends of the ports 24, 25 are threaded to receive conduit pipes. Thus, as the disc 6 is rotated, the balls 3 are caused to rotate about horizontal axes compressing the diaphragm and so partitioning the groove 2 into three chambers carrying the fluid from the inlet 24 to the outlet 25. To prevent knocking, a compensating slot 31, 32, providing communication between the two sides of the lug 21, may be formed in the groove 2. The device may be used as a flow meter using the pressure of the incoming fluid to rotate the balls 3 and hence drive the shaft 7, the shaft being coupled to suitable registering mechanism. Instead of the lug 21, the groove 2 may be partitioned as in Fig. 5, by using a bolt 33 to draw the diaphragm locally into the groove. Instead of the cage 6, the balls may be held in recesses in a plate 36, Fig. 6, by an outer ring 37. The diaphragm 4 may be reinforced by an elastic insert such as one or more endless wires or by synthetic fibrous material. The resilient means 10 is so chosen as to limit the pressure acting on the fluid. If this pressure is exceeded the disc 6 may be shifted axially and so actuate control means to stop the drive. Means may be provided for adjusting the tension of the spring 10 during operation of the device. To prevent the diaphragm being forced upward between the balls 3, tapered rollers 39, Fig. 9, may be placed between the balls. The rollers 39 are held in position by a bell-shaped member 40, which may be positively driven by the shaft 7<SP>1</SP> and is coupled to the disc 6<SP>1</SP> by pins 8. A common cage 44 houses the balls 3 and the rollers 39. The rollers may have a central spherical bulge.

Abstract: 697,087. Discharge lamps. GRABER, H. Dec. 28, 1949 [Dec. 28, 1948], No. 33160/49. Class 39(i) A discharge lamp (Fig. 1) comprises coaxial inner and outer cylindrical vessels 2, 1 with a single and continuous insulating ribbon 9 arranged spirally and edgewise in tight contact with the vessels to form a helical discharge path at the ends of which are the electrodes 10, 11, fluorescent material covering at least a part of the inner wall of the outer tube, a filling of at least one rare gas and a metal vapour at low pressure in the space between the vessels, and an incandescent filament in the inner cylinder. The two vessels may be interconnected or the inner one filled with a gas e.g. nitrogen or argon at the usual incandescent lamp pressure. The discharge filling may be argon or krypton and mercury. The incandescent filament 12 serves as a ballast resistance in the electrode circuit of the lamp, and is connected to the middle contact 13 of the socket 8 and the electrode 11 respectively. In larger lamps the inner vessel 2 may be bottle-shaped with a restricted neck and a broad flange which is afterward sealed to the outer vessel. In a modification, Fig. 2 (not shown), the supply lead to the incandescent filament passes through a long glass tube in the inner vessel 1. The fluorescent material has a predominantly green emission to compensate for the red emission of the filament. When the two vessels are interconnected, the filament may require special screening to prevent arcing.
