Title: Laminated packing for sealing joints
IPC: F16J15/20
Filed: 1956-10-05
Abstract: 814,022. Stuffing-box substitutes; jointmaking packing. MULLER, J. Oct. 5, 1956 [April 17, 1956], No. 30426/56. Classes 122 (3) and 122 (5). [Also in Group XXIX] A laminated packing for sealing rotary or sliding joints is made by winding a thin strip of suitable material, e.g. metal or plastic, on to the outer or the inner periphery of an annular support having a width less than the stirp, and bending the structure so formed by means of annular complementary parts of suitable shape so that the projecting edges of the strip are deflected obliquely towards the inside periphery, if wound on the outer periphery, or towards the outer if wound on the inner periphery. For use in sealing a rotary shaft 1, Fig. 1, in a fixed housing 8, the packing consists of a strip 3 wound over a ring 4, and having its edges bent inwardly by frusto-conical clamping members 5, 6 which are held against rotation by dowels 12, the assembly being secured together by screws 7; the assembly so formed is inserted over the shaft 1 into the housing 8 and held in place by a member 10 with intervening springs 11. The edges of the strips may be notched or bored to engage the shaft. In the pipe-coupling shown in Fig. 3, two packings 3 bear respectively inwardly on the pipe 1 and outwardly on the coupling member 18; axial pressure is applied through a wire spring 24 of sinuous form which is secured to the ring 16 by screws 25; a plastic sheath may be provided on the spring 24. When applied to the face of a mushroom valve, Fig. 7, the head of the valve is made in two portions 29, 30 clamped together with the packing 33 wound on to the inner periphery of a ring or spring 34 and bent outwards to form two wings which engage the valve seat. The upper valve disc 30 has a recess 35 to admit pressure fluid to the rear face of the packing to improve the seal. To reduce puckering during the bending of the strip after winding to the required thickness, the edges of the packing material may be notched. For large packings the strip may be of several sections welded or stuck together.

Title: Ball bell ringer
IPC: G10K1/068
Filed: 1965-07-19
Abstract: 1,063,590. Bells. GUSTIN-BACON MANUFACTURING CO. July 19, 1965 [Feb. 25, 1965], No. 30499/65. Heading G5J. The Figure shows a compressed-air bell ringer in which a striking ball 67 is blown through a guide 32 by air pressure and returns to its seat by rolling under gravity at the conclusion of the cycle. Air is fed through an opening 23 into a reservoir 19 until with increasing pressure the thrust on the exposed head 49 within the reservoir of a piston 49, 49B becomes large enough to overcome the resistance of a spring 55. When the piston moves from its seat 50 the air in the reservoir obtains access to the body 49B of the piston which is of larger diameter than the head. The force on the piston is increased accordingly, and it is depressed fully, uncovering the passages 43. In its escape to the atmosphere through these and the connected opening 33 the air dashes the ball 67 against the bell skirt 10. When the pressure in the reservoir has fallen sufficiently, spring 55 returns the piston to its seating and the building up of pressure begins again, while the striking ball rolls to its original position under gravity in preparation for another cycle.

Patent GB-926392-A (GB)
Title: Process for the extraction of beryllium
IPC: C22B35/00
Filed: 1960-09-06
Abstract: Beryllium ores containing phosphate, e.g. beryl associated with apatite, are leached with a mineral acid to remove phosphate and the leached concentrate is roasted with an alkali metal silicofluoride or ferrifluoride to form the alkali metal beryllium fluoride which is leached out with water.  Beryllium hydroxide is precipitated from the leach liquor with sodium hydroxide.  The beryllium hydroxide is separated from coprecipitated hydroxides, e.g. those of iron and aluminium, by treating with sodium hydroxide at 40 DEG -55 DEG C. to redissolve the beryllium, filtering, and boiling the filtrate when granular beryllium hydroxide of at least 99% purity is precipitated. The mineral acid leaching may be carried out at room temperature, when the optimum acid normality is 2, but it is preferably carried out at 80 DEG -95 DEG C. when the normality is at least 4.  The roasting is carried out with at least 30% by weight of the above fluorides, preferably at 700 DEG C. for at least 2 hours.  Sodium carbonate may also be added before roasting.

Title: Improvements in or relating to apparatus for indicating or recording numerically the measurements effected by measuring apparatus
IPC: G01G23/36
Filed: 1933-11-04
Abstract: 428,369. Recording apparatus. LEVY, M. A. E., 12, Rue DÚsirÚ RuggiÚri, Paris. Nov. 4, 1933, No. 30673. Convention date, Dec. 2, 1932. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 8, 1934.] [Class 106 (iv)] [See also Group XXXVIII] In a system for indicating or recording the indications of an instrument, of the type wherein the instrument pointer cooperates with a follow - up member driven by a motor which also directly operates the indicating or printing wheels of an indicating or registering apparatus, the indicating wheels are provided with means for effecting correct alignment, the aligning means being brought into operation automatically. As shown, the pointer A of a measuring apparatus, e.g. a weighing-machine, co-operates with a follower member A 1 driven by a motor M which sets the printing wheels R, S. When a weighing operation takes place, contacts K are closed and relays F, G, EC are operated. Relays F, G lock up and close the motor circuit. The relay EC operates the follower pointer A<1> into the plane of movement of the instrument pointer and when the pointer A<1> overtakes the pointer A, relay C is operated to de-energize relay G and open the motor circuit. The printing wheel R, and also through gearing the wheel S, are thus adjusted into positions corresponding to that of the pointer A. Upon release of relay G, relay E at the printer is operated to lock the wheel R, the wheel being correctly set by the co-operation of the armature with the triangular notches on the wheel. In positions other than the zero position of the wheel R, operation of relay E closes the circuit of a motor m, over a circuit including contact f and a contact ring on the wheel R, the motor being adapted to drive the printing wheel S. The wheel S is connected to its shaft by a spring and the motor m is adapted to drive the wheel S in opposition to the spring control so as to align correctly the wheel S through the medium of the pallets a and a stop bu which is moved into the path of the pallets upon operation of the electromagnet E. Co-operation between a pallet a and the stop bu also completes the circuit of the printing magnet EI. When the magnet EI is operated relay D is energized to effect release of the operated relays and restore the equipment to normal. The aligning notch in the wheel R at the zero position is deeper than the remaining notches so that if the wheel R is brought to rest in its zero position, the armature of the electromagnet E is allowed a longer travel and contacts 2 of the electromagnet are closed to energize directly the printing magnet E1.

Title: Improvements in or relating to cathode diaphragm structures for electrolytic cells
IPC: C25B13/06
Filed: 1957-10-01
Abstract: <PICT:0828659/III/1> A process for making a combined cathode and diaphragm structure for electrolytic cells comprises treating a perforated cylindrical cathode with an aqueous suspension of a fibrous material, e.g. asbestos, and subjecting the suspension to a positive pressure, e.g. 3 to 12 lbs. per square inch, to deposit a uniform layer of asbestos on the interior of the cathode.  A perforated steel cylindrical screen 20 is mounted between a pan 2 and a top 3 interconnected by tie bolts 4, 5 and the suspension of suitable viscosity delivered by a pump 6 to the interior of the cathode 20. Some suspension escapes through the screen 20, the level in the screen rising until a pipe 10 is reached, when a valve 11 is closed to maintain the desired pressure inside the screen 20. After a time, e.g. 9 minutes, the supply is arrested, and a drain 24 opened, air under pressure being admitted at 15, e.g. at 5 lbs. per square inch, to force out excess suspension.  The air may be maintained, e.g. for 30 minutes, after draining, with the drain 24 closed, for drying.  The aqueous liquid for the suspension may comprise a solution of 100 to 150 gms. per litre of sodium hydroxide and 150 to 210 gms. per litre of sodium chloride.  The asbestos content may be 15 to 20 gms. per litre.

Abstract: 1495923 Yarn brake for 2:1 twisting spindles HAMEL GmbH ZWIRNMASCHINEN 26 July 1976 [26 Sept 1975] 31011/76 Heading DID A yarn brake in a 2:1 twisting spindle comprises a yarn brake housing having a yarn guide channel 22, 26, 34 therethrough, the channel being formed of at least one bore having at least two openings 28, 30 and at least one yarn brake face 36 or 38 in the region of one of these openings, and a brake body 42 which closes the opening to brake the yarn. The brake body 42 is movable sideways into a threading position (Fig. 2) wherein the opening 28 or 30 is not obstructed and wherein a longitudinally slit bridging tube 78 is moved to bridge the two openings 28 and 30 and form part of the yarn guide channel. As described, a spindle includes a telescopic yarn brake 18 bearing against pressure members 14, 16. When it is required to thread up the spindle, the yarn inlet tube 32 is pressed downwardly so as to compress the telescopic yarn brake 18 and then engage bridging tube 78. On further downward pressure the bridging tube is forced sideways so as to bridge the yarn guide channels 30 and 28 and at the same time force the yarn brake 18 sideways to the position shown in Fig. 2. When the bridging tube is in position a continuous yarn guide channel is formed from one end of the spindle to the other. The pressure member 16 is urged by a spring 72 against adjustable stop 56. The position of the stop bush 56 can be varied by rotation of sleeve 50 which is in screw threaded engagement with stop bush 56. The adjusting sleeve 50 may be provided with a ball catch to locate the adjusting sleeve in predetermined angular positions. In an alternative embodiment, two telescopic brake tubes and pressure members are provided within the spindle, each telescopic brake being movable by an associated bridging tube located within the associated brake housing. The arrangement is such that compression of the yarn inlet tube first moves one of the telescopic brake tubes sideways and upon further pressure the second of the brake tubes is moved sideways so as to form a continuous yarn guiding channel through the spindle by means of the two bridging tubes, Figs. 4-6, not shown. In a further embodiment. Figs. 7-9 not shown, one of the yarn brakes is formed by a set of balls which are moved from the braking position on compression of the spindle by a tube which emerges from the yarn guide channel to connect with a yarn guide channel on the other side of the brake housing. In this embodiment, the second yarn brake is formed by a telescopic yarn brake and associated bridging tube. The yarn inlet tube(s) may be compressed by a pneumatic yarn threading device.

Title: Improvements in, or relating to, the gripper mechanism of axminster-carpet and othertufted-fabric looms
IPC: D03D39/02
Filed: 1946-10-22
Abstract: 624,883. Tuft grippers for pile fabric looms. BRINTONS, Ltd., and BRINTON, C. C. Oct. 22, 1946, No. 31313. [Class 142 (ii)] Tufts of pile yarn are drawn from a supply and placed in position for incorporation in the fabric by two rows of jaws 18, 18a carried by an intermittently rotated beam 1. The rows of jaws are made up from sections each loaded by a spring 21. When at position 5, the jaws are projected from the beam by endwise movement of a slide 8 pushed by a rod 33 (the slide 8 having diagonal channels 14 engaging ribs on the jaws 18a) ; this movement takes the jaws up to the yarn supply 29 and also engages a rod 24 with an operating rod 31, which pulls it endwise to rock cams 22 and thereby close the jaws on to the ends of the yarns 28. The slide 8 is then pulled by the rod 33 to its original position, thus retracting the jaws which accordingly draw lengths of yarn from the supply; the cutter described in Specification 624,882 then cuts off the tufts from the supply. Meanwhile, the tufts held at 5a by the other jaws have been embodied in the fabric and are now released by a rod 30 pushing a rod 24a to open the jaws ; also, a siide 8a is operated by a member 36 to retract the jaws, after which the beam 1 is turned through half a revolution. During this movement, a roller 35 on the slide 8 . enters a channel 37 (concentric with the beam 1) in the member 36, and the member 36 is operated to project the jaws into the position 5a.
