Title: Improvements in Looms for Weaving Double Pile Fabrics.
Inventor: HOLLINGWORTH EDWARD
IPC: D03D39/16
Filed: 1917-09-20
Abstract: 116,625. Hollingworth, E., (Crompton & Knowles Loom Works). Sept. 20, 1917. Picking-motions; shuttles; beat-up motions.- In weaving double-pile fabrics such as coco-fibre mats, the wefts are inserted by shuttles actuated by positively-operated plungers, and first moved through the sheds to an intermediate position beyond the selvedge, whereupon the lay is moved partially forwards to beat up the wefts together with the plungers without changing the sheds, and the movement of the shuttles is then completed to tighten the wefts laid in the sheds, the plungers are withdrawn, and the lay makes a complete forward movement to beat up the wefts a second time, the shedding of certain of the binder and selvedge warps being changed during this beat-up and the subsequent withdrawal of the lay; the plungers then make a complete movement and draw the shuttles back through the sheds, the lay beats up the wefts, and the remaining binder and selvedge warps and the pile warps change shed. In a modification, the shuttles are pushed through the sheds by plunger mechanism arranged at each side of the loom. The shuttles 16, Fig. 1, are actuated by plungers 17, which are guided by rolls 19 and attached to a head 18 slidable on the lay 12. A chain 20 has its ends connected to the head 18, is guided by pulleys 21, and surrounds an actuating-pulley 22 provided with an attached pinion 24 gearing with a toothed segment 25 pivoted at 26 and adjustably connected by a rod 48 to a crank 46 secured to a pinion 44 on a stud 45. A partly-toothed wheel 43 driven by bevel-gearing from the driving-shaft 30 actuates the pinion 44 at the proper time to give the desired movements to the plungers and the shuttles. Each shuttle 16, Fig. 5, has a hook 62 pivoted at 63 and acted upon by a strong spring 64 and a weaker blade spring 65 so that it is normally held in position to engage a recess in a flattened head 60 on the plunger 17, but, when the lay moves forwards, a spring-pressed roller 66 on the breast beam or other part reinforces the blade spring 65 and disengages the hook 62 from its recess to free the shuttle from the plunger. The lay 12, Fig. 2, is pivoted at 11 and connected by rods 31 to arms forming part of and movable with a three-armed lever 32, of which the arms 32a, 32<b> have rollers 34, 36 at their ends adapted to be acted upon by cams 35, 37 on the shaft 30, the cam 35 being shaped to move the lay forwards at the proper times and the cam 37 to initiate the backward movement, which is effected by heavy springs 38. In the modified loom, the chain mechanism for actuating the shuttles is duplicated, both sets of mechanism being actuated by one partly-toothed wheel, the shuttles are not adapted to engage the plungers, but are merely pushed through the sheds thereby, and the beating-up cams are formed with duplicate halves.

[Class 139.] Escapements.-In a timepiece regulated by two independent escapements driven respectively by branches of the train, bifurcation of the train is effected differentially by spur gearing. The seconds hand 16, Fig. 1, is carried by a shaft 3, driven by the train through gearing 5, 4 and driving through gears 19, 20 the planet member 20, 21 rotatably carried in the gear wheel 17 which is rotatably mounted on shaft 3 and drives through pinion 14 the escape wheel 15. The gear wheel 21 of the planet member meshes with a wheel 22 rigid with the wheel 18 which is also rotatable about shaft 3 and drives through pinion 12 the escape wheel 13 (the regulating members of the escapements not .being shown). The gearing is preferably such that the two escape wheels rotate equally. Each of the two branches may be again bifurcated, when four escapements may be used. The Specification as open to inspection under Sect. 91 describes a modification in which the planetary member of differential mechanism comprises an arm 10, Fig, 1 (Cancelled), fixed to shafts 3 and rotatably carrying a conical pinion 11 meshing with the contrate teeth of wheels 6, 8 which are rotatably mounted on shaft 3, and drive the escape wheels 15, 13 through the pinions 14, 12 respectively. To obtain different speeds for the wheels 6, 8, the contrate teeth thereof may engage separate wheels 25, 24, Fig. 3 (Cancelled), both rotatably mounted on the arm 10, Fig. 1 (Cancelled). This subject-matter does not appear in the Specification as accepted.

Filed: 1925-05-27
Abstract: 237.225. National Bundle Tver Co., (Assignees of Saxton, A. H.). July 18, 1924, [Convention date]. Parcelling by bundling.-Relates to machines for tying bundles or objects. The object 35, Fig. 1, is placed on a rack 26 supported by an arm 25 pivoted at 27, and depresses a lever 42 pivoted to a portion 43 of the frame of the machine. A spreading block 47, Fig. 5, is thereby lifted from between clutch members 48, 49 which are then urged into engagement by a spring 51 to clutch a shaft 30<a> and a gear wheel 31 rotated from a motor 2<a>. The rotation of the shaft 30<a> causes, through arms 28 - - 30, the arm 25 on the shaft 27 to be rotated and to lift the object into position beneath a needle 13. The cord 14 is disposed from the knotting mechanism 20 through the needle 13, tension device 16, and guide 15 to the supply 18. The movement of the object into position beneath the needle disposes the cord around itself so that the knotting may be completed. The arm 25, in rising to its uppermost position, actuates a lever 65 to cause rotation of a shaft 22 driving the knotting mechanism, and at the same time a presser foot 76 is caused to descend and compress the bundle on the line of the application of the cord. The presser foot is moved by a parallel link movement 80, 82, Fig. 5, the member 82 of which is raised by an arm 89 through the medium of springs 88, so that a yielding pressure is produced to accommodate bundles of varying sizes. The arm 89 is operated from an oscillatable shaft in connection with the needle actuating mechanism. A spring device 60 on the arm 28 enables the connection between the arms 28, 30 to yield in the event of an obstruction to the movement of the arm 25. The machine may be started manually or by pedal action.

Abstract: 514,627. Treating sewage &c. COOMBS, J. A. May 10, 1938, No. 13901. [Class 111] In a process for treating sewage or like liquids comprising primary and secondary flocculation and settlement stages, sludge collected in each stage being returned to liquid entering the stage, the sludge is supplied to each stage through injectors which project into the liquid in the tanks and have inlets through which air is drawn in by the sludge, In the construction shown in Fig. 1 a channel 20 is provided for water sewage which is drawn into a settlement zone 21 by means of ejectors 24. Sludge from the zone 21 is scraped into a sump 26 by mechanism 27, which may be as described in Specification 514,662. The sludge is withdrawn from the sump by a pneumatic ejector 31 which may be as described in Specification 438,132, [Group XXVIII]. This ejector delivers the sludge to a de-watering tank 30, the effluent from which flows through a tank 37 back to the channel 20. Part of the sludge in the tank 30 is drawn through pipe 38 into the zone 21 by means of the ejectors 24. the remaining sludge being discharged through pipe 41 to de-watering beds 42. The ejectors 24 are adapted to deliver air, and if varied chemicals such as alumino ferric, as well as the crude sewage and sludge. The zone 21 is separated by a screen 43 from a secondary zone 22, the sludge from which is removed by a pneumatic ejector 32 and delivered to a tank 33. Here the sludge is re-activated by air discharged in a finely-divided state and is then returned to zone 22 through ejectors 25. Effluent from the tank 33 is returned to the channel 20. In a modification shown in Fig. 8, an aeration zone 65 is provided between the zones 21, 22, air being diffused into the sewage through porous stone diffusers. The re-activation tank 66 is of cylindrical form and is closed. compressed air being delivered to the sludge. After reactivation, the sludge is discharged through a high stand pipe 67 into a tank 69 from which it is returned to the zone 65 by the ejectors 25. The de-watering beds for receiving the sludge may be contructed as shown in Fig. 12, each comprising an upper layer 88 of cinder and a lower surface 89 of clay. The sludge is delivered to the bed through pipes 86 and liquid is drained off through a sump 90 with a perforated cover 91. Rails 94 are provided to support a "mechanical labourer" 95 which may be as described in Specification 496,637. Surplus sludge may be used for the manufacture of fertilisers as described in Specification 496,547. Specification 115,872, [Class 111,], also is referred to.

Abstract: 376,736. Knitted fabric. WILDT, E., HOLMES, H. H., and WILDT & CO., Ltd., Adelaide Works, Leicester. April 9, 1931, Nos. 13982/32 and 13983/32. Divided on 376,350. Drawings to Specification. [Class 74 (ii).] Knitted fabric having non-laddering properties is produced from ground and warp loops knitted together or inter-locked, the latter lying on the rear face of the fabric. The warp loops may, in places, appear on the front face of the fabric or be absent altogether from some wales. Generally, the ratio of the diameters of the ground and warp yarns is 1.4 to 1 or over. In a preferred method of carrying the invention into effect the warp yarns are made to appear on the rear face by adjusting their tensions relatively to the ground yarn. In a method illustrated by drawings, each warp yarn is first wrapped round its needle and subsequently the ground yarn is laid on the needles, but this order may be reversed. Specifications 313,657, 327,958, 327,987, 327,988, 328,026, 331,930, [all in Class 74 (ii), Knitting &c.], 347,307, 364,108, are referred to.

Title: Improvements in the purification and decolorisation of aromatic hydroxy-carboxylic ac
IPC: C07C51/487
Filed: 1932-05-17
Abstract: Aromatic hydroxycarboxylic acids, more particularly salicylic and the cresotinic acids, are purified by treatment of a solution of a salt of the acid with a precipitated oxide, hydroxide or carbonate, including basic carbonates, of zinc or aluminium, which may be either formed in the solution by precipitation or precipitated separately and introduced moist into the solution. The process may be used in conjunction with known purification methods.  According to examples, (1) crude sodium salicylate in a solution made slightly acid is heated with decolorizing carbon, zinc dust, and crystallized zinc sulphate, followed by the addition of sodium carbonate, filtering, adding sodium sulphite and precipitation in the usual manner; (2) crude sodium o-cresotinate is first treated by precipitation by acid from aqueous solution, dissolved in caustic alkali, rendered slightly acid, and treated with decolorizing carbon and the procedure of example (1).  The Provisional Specification refers in general to the use of insoluble carbonates, hydroxides, or oxides of metals of groups II and III of the Periodic System for purifying aromatic hydroxycarboxylic acids and their homologues and derivatives

Title: Improved means for shifting heavy machines
IPC: B66F3/36
Filed: 1948-05-25
Abstract: 643,934. Hydraulic propulsion means for vehicles, COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL SOC. ANON. May 25, 1948, No. 14098. Convention date, June 3, 1947. [Class 79 (iii)] [Also in Group XXXII] An appliance for shifting vehicles and heavy machines mounted on rollers which comprises a hydraulic jack of which the two elements that are movable relatively to one another are connected by at least one return spring, one of said elements being connected to the vehicle or machine, is characterized by the feature that the other movable element is articulated to a bearing member which is adapted to press upon the surface in relation to which the vehicle or machine is to be displaced. In one embodiment, shown applied to a rail vehicle, the vehicle 1 is provided with a rearwardly extending bracket 5 pivotally connected at 7 to the cylinder 6 of a hydraulic jack of which the piston 8 is articulated at 9 to a claw 10 supported on a rail 3. The claw comprises two side plates rigidly interconnected adjacent their rear edges by a transverse plate which rests on the top surface of the rail, each plate being fitted on its inner surface with a block shaped to conform to the under portion of the rail head. The side plates are extended forwardly to support a roller 19. When hydraulic fluid is admitted to the jack through a flexible pipe 11 extension of the jack causes the claw 10 to rock rearwardly and bind the transverse plate and the shaped blocks on the rail to cause forward movement of the vehicle. Release of fluid pressure enables the jack to be retracted by tension springs 12, the claw 10 trailing along the rail on the roller 19. In a further embodiment (not shown), applied to a machine mounted on rollers, the bracket 5 is attached to the machine by a vertical pivot to enable the jack to displace the machine in any direction, for which purpose the lower end of the piston 8 is attached by a universal joint to a sole plate which rests on the supporting surface. To ensure that the jack does not approach too closely a vertical position, the bracket 5 is provided with an adjustable stop.
