IPC: D03D43/00
Filed: 1916-01-11
Abstract: 103,146. Owen, H. A. Jan. 11, 1916. Weft-replenishing mechanism. -- In deferredaction indicating-devices for deferring weftreplenishment until the weft-feeler devices have acted a given number of times so that the fresh weft is picked into the same shed as that in which weft-failure was detected &c., a loose travelling actuator is guided in such a manner that it is conducted by stages from its starting point into a path in which it produces the desired indicating action and automatic means are provided for restoring the actuator to the starting position. An actuator in the form of a ball 14, Fig. 5, normally rests between walls 9x, 9y of the weft-fork slide 9 in a pocket 15, Fig. 6, in a raised portion of the base 13. When the weftfork 10 is engaged by its hammer hook 11, the slide 9 is moved forwards and the ball is moved into a groove 16 by the wall 9<x>. When the slide returns, the wall 9y moves the ball back along the groove 16, which is deepest at the side nearer a rib 16<c>, so that the ball is guided into a second pocket 15<a>. A second successive movement of the weft slide transfers the ball by way of a groove 16<a> into a third pocket 15<b>, and a third successive movement causes the ball to enter a groove 16<b> and act on a projection 5<a> of a lever 5 for actuating the weft-replenishing mechanism. Any desired number of pockets and grooves may be provided, and one or more pockets may be rendered inoperative by means of an adjustable blocking-screw inserted into the slide 9 either from the top cr from the side remote from the lever 5. Automatic return of the ball to the starting pocket is effected, when the slide 9 is not moved forwards, by a spring-controlled pivoted replacer 17 having a tail-portion 17<c>, which is struck by an adjustable screw 20 on the wefthammer 12 to raise the upper inclined edge 17<a> of the replacer, the ball running down the incline into the pocket 15. The base 13 is adjustably secured to the breast beam 2 by screws 13<e> and slots 13d, and the lever 5 is adjustable longitudinally by its being pivoted round an adjustable eccentric bushing.

Patent GB-630150-A (GB)
Title: Improvements in and relating to the hardening of proteinaceous substances
IPC: B29C48/00
Filed: 1947-01-08
Abstract: Proteinaceous material such as casein or zein is hardened by reaction with a methylol melamine ether.  The hardening takes place as a result of the formaldehyde liberated, and the resinification of the ethers produces a hydrophobe matrix within the protein mass. Preferably, a pure methylol malamine ether is used which may be obtained from a mixture of ethers by extraction with petroleum ether. Such an ether may be obtained by stirring melamine with formaldehyde and ammonium hydroxide, cooling, drying, dissolving in a methanol aqueous hydrochloric acid mixture, neutralizing, filtering, evaporating, repeatedly extracting with petroleum ether and recrystallizing therefrom. Catalysts such as maleic acid, tartaric acid, succinic acid oxalic acid and similar carboxylic acids may be incorporated and the hardening may thus be effected without heat. Plasticizers may also be incorporated.  Examples show the water sorption of sheets made by hot-pressing compositions of (1) zein and hexamethylol melamine butyl ether, (2) and (3) rennet casein, hexamethylol melamine methyl ether, oxalic acid and water, (4) zein, hexamethylol melamine methyl ether and oxalic acid, (5) zein, hexamethylol melamine methyl ether, para tertiary amyl phenol and oxalic acid.ALSO:Proteinaceous material such as casein or zein is hardened by reaction with a methylol melamine ether.

Title: Improvements in or relating to well drilling apparatus
IPC: E21B19/08
Filed: 1930-01-09
Abstract: 348,561. Well drilling. LOOMIS, W. A., 229, N. Citrus, Whittier, California, U.S.A. Jan. 9, 1930, No. 850. [Class 85.] In well-drilling apparatus, the cable-winding device is adapted to be automatically controlled solelv by variations in the tension in the drill-string supporting cable produced by variations in the load-sustaining qualities of the earth formation against which the drill acts, so as to maintain said tension within predetermined limits. In Figs. 1 and 2, the drill string is suspended from a cable 20 passing from the drawworks drum 24 round a pulley block 19 to a drum 23 adapted to be driven through a chain 15 either from a band wheel shaft 13 or sprocket 41 through clutches, the operating levers 18, 45 of these clutches being connected by a link 46. The sprocket 41 is driven from a reversible motor 27 through flexible coupling 95, Fig..2, a shaft 37 on which a worm 34 is slidably splined, and a worm wheel 40. A spring-applied, magnetically-released brake 31 controls the motor shaft. The worm 34 bears against a diaphragm 54 closing a chamber 53 containing incompressible fluid and connected through pipe 69 to a similar diaphragm chamber 68 connected through a rod 65 to a third diaphragm chamber 70 containing inelastic fluid and connected by pipe 71 to a cylinder 72 containing a screw plunger for varying the pressure ; an air pocket 76 is provided in the pipe 71 to give elasticity. The rod 65 carries a contact 64 moving between contacts 63a, 63b. The drilling pressure is estimated either by a device 25, Fig. 1, as in Specification 311,714, [Class 85, Mining &c.], or by a gauge 26<1>, Fig. 2, connected to the diaphragm chamber 53. In use, manual control of the drilling pressure is effected by means of switches 48, 49, Fig. 2. For automatic control, switches 50a, 51a, are closed, whereupon excessive tension on the cable 20 acts through chain 15, sprocket 41 and worm wheel 40 to slide the worm 34 against the diaphragm 54 thereby moving rod 65 to bring contacts 64, 63a together to cause a relay switch 58 to close motor circuit 50<1> ; the brake 31 is then freed and the motor 27 is driven to lower the drill-string. If the drilling pressure is to be reduced, the pressure in diaphragm chamber 70 is increased by adjusting the plunger 73 ; if the increase in pressure brings contacts 64, 63b together, a relay switch 581 closes a motor circuit 92 and the motor 27 is driven to apply a lift to the drill-string. In a modification, Fig. 3, the diaphragm chambers are omitted, a member 651 being forced against the worm by a spring 79 bearing against a stop 80 adjustable by threaded connection to a sleeve 81 ; the member 65<1> operates the contact member 641 directly or through a toothed segment 83.

Abstract: 477,733. Projectile fuzes. MANUFACTURE D'ARMEMENTS ET DE MUNITIONS ARMU SOC. ANON. Jan. 11, 1937, No. 852. Convention date, Jan. 9, 1936. [Class 9 (i)] A projectile, such as a bomb or grenade, is provided with a percussion fuze 6 comprising a first movable mass 8 having re-entrant upper and lower faces, the former fitting against the conical wall of a depression 7 in the head of the fuze and the latter against the conical face of a freely mounted ring or washer 9 which carries on its opposite face the firing pin 10. A further conical ring or washer 11 bearing the percussion cap 12 is disposed opposite the washer 9 and a light spring 13 is interposed between these two washers. A second mass 14, similar in shape to the mass 8, is arranged between the washer 11 and a conical washer 15, the rim of which is clamped between the lower edge of the fuze head and a shoulder 16 on the bomb body 5. The percussion cap 12 is connected to the detonator 18 by means of retarding means, such as the cord 19, which passes through the central passage 17 in the mass 14. A housing 20, which separates the fuze from the charge in the body 5, is held by its edge between the washer 15 and shoulder 16. According to a modification, Fig. 3 (not shown), the detonator is mounted in a central aperture in the housing 20 and the cord 19 is dispensed with. In order to prevent accidental firing of the bomb, a resilient blade or strip 21 is held in position on the head of the fuze by a rigid U-shaped hood 24 so that pins 22 on the ends of the strip 21 engage in holes 23 in the fuze head and interpose themselves between the washers 9 and 11. The blade 21 and hood 24 are disposed one above the other in a bracket 25 on the fuze head and are held therein by means of a safety-pin 26. The bomb shown may be fired from a mortar or released from a tube on an aircraft, in which case the hood 24 is removed at the moment of introduction of the bomb into the firing or launching tube, the wall of which then maintains the blade 21 in the compressed state. When the bomb leaves the tube, the blade opens under the action of its elasticity and disengages itself automatically. The bomb may also be used as a hand grenade, in which case the hood may be first removed and the blade kept in place by the pressure of the hand or the hood may be removed only at the moment when the grenade is thrown. At whatever angle the bomb strikes an obstacle, the masses 8, 14 are displaced towards one another and cause the washers 9, 11 to move towards one another against the action of the spring 13, thus producing the instantaneous firing of the percussion cap 12.
