Title: Improvements in small hand or treadle operated printing presses
IPC: B41F1/26
Filed: 1950-03-03
Abstract: 691,112. Platen printing-presses. AYERS, F. P. May 29, 1951 [March 3, 1950], No. 5430/50. Class 100(ii) Relates to small manually-operated printing- presses of the type referred to in Specification 452,450, comprising a body 1, a type bed 11 mounted in a substantially vertical position on the body associated with inking mechanism and a platen 5 hinged transversely across the body and adapted to be pressed on to the type by a lever 7-8 pivoted on the body. According to the invention the platen is provided with a lever 13 extending past its hinging axis and co-acting with a compression spring 20, rubber block or equivalent shock damping device mounted on the body 1 of the press, and so disposed that movement of said lever during movement of the platen to its open position is resisted by said shock damping device. In the form shown the body 1 is hollow and the lever 13 is pivoted on the platen shaft and moves with the platen, one arm 15 of the lever extending through a slot 16 in the rear of the body to operate inking mechanism in synchronism with the platen movement, and a further stub arm 17 of the lever extending downwardly, and being bifurcated to form two cheeks which are disposed one on each side of a rod 18 carrying the spring 20. As the platen 5 returns to its open position, a block 19 journaled in the cheeks of the lever arm 17 moves rearwardly along the rod 18, its movement being damped by compressing the spring 20. Any tendency of the rod 18 to move during forward movement of the platen is resisted by a further spring 22 mounted on the forward end of the rod 18. The cushioning effect of the spring 20 may be varied by means of an adjusting nut 36 provided at the forward end of the rod 18 and bearing on the exterior of the body 1.

The graft polymer formed is recovered from the latex by coagulation and cured.
Patent GB-645761-A (GB)
Title: Improvements relating to the saponification of cellulose acetate textile materials
IPC: D06P5/22
Filed: 1948-02-24
Abstract: Textile materials comprising fibres of cellulose acetate of acetyl value (calculated as acetic acid) above 56 per cent are partially saponified so as to reduce the acetyl value to 53-55 per cent.  The treatment improves the dyeing properties of the materials.  Although of relatively high acetyl value, materials may be obtained which have affinity both for cotton dyes and for cellulose acetate dyes of the dispersed insoluble kind and which can be dyed with cotton dyes without substantial variation in depth of colour.  The materials may be treated in the form of stretched or unstretched yarns in hank, skein, bobbin, cone, or other package.  They may be treated in the form of staple fibres or in fabric form.  Travelling yarns may be passed slowly and continuously through a heated saponifying bath. Saponification is preferably effected by treatment of the materials with a 1-5 per cent solution of sodium carbonate at 80 DEG -100 DEG C.  The heat resistance, including resistance to glazing by a hot iron, is also improved by the treatment.  The cellulose acetate fibres or yarns may be associated with wool, silk, cotton, or regenerated cellulose fibres.  In an example cellulose acetate of acetyl value 59 per cent is spun into filaments from a solution in methylene chloride and alcohol.  The yarns obtained are immersed for 1 hour in 2.5 per cent sodium carbonate solution at 97 DEG  C. until the acetyl value is about 55 per cent.  The Specification as open to inspection under Sect. 91 comprises also the saponification of materials of cellulose acetate of combined acetic acid content of 54-59 per cent or of another cellulose organic ester of equivalent degree of esterification, and the saponification may be continued till the combined acetic acid content has been reduced to 85-93 per cent of its original value.  This subject-matter does not appear in the Specification as accepted.

In an automatic machine tool means are provided for machining the end of a workpiece after parting off from a stock bar, the means including a workpiece transferring device and comprises rotatable coaxial spindles 16 and 22 offset from the machine spindle axis. The spindle 16 carries a tool holder 42 and tool 40 located in an endhousing 18. Spindle 22 is keyed to the spindle 16 and is axially slidable therein. One end of the spindle 22 is provided with an oblique transverse face 36 which co-operates with a similar face on the base of the tool holder in the end housing 18. Axial movement of the spindle is effected by a pivoted lever 30 actuated by pneumatic means 32. The spindles 18 and 22 are driven through gearing 20 from an electric motor so that to perform a shaping operation simultaneous rotation and transverse movement of the cutter 40 is effected. The transfer means provided for moving the workpiece 6 from the bar stock after parting off comprises jaw members (44), Fig. 2 (not shown), 46 attached to a pivotable arm (50), Fig. 2 (not shown). The jaws loosely hold the workpiece 6 in the position shown in Fig. 1, during parting off and then the arm (50) is rotated to bring the parted off workpiece into line with the axis of the shaft 22. Clamping means in the form of a wedge actuated by pneumatic means 60 effects the gripping of the jaws on the workpiece prior to the shaping or machining operation by the tool 40.

Abstract: 249,835. Compagnie Industrielle de MÚcanique HorlogÞre. March 27, 1925, [Convention date]. Alarm mechanism; wheels, pinions, and arbors. -Figs. 1 and 4 illustrate the known art in which a ratchet wheel 3 on the arbor 2 of the alarm spring 1 carries freely on it a wheel 4 which has a spring-pressed pawl 15 coasting with the teeth of the ratchet. This wheel 4 drives a pinion 8, centre wheel 9, pinion 11 and third wheel 13. Usually a dome-shaped spring 14 is clinched rigidly in an extension 15 of the ratchet wheel 3 and bears upwardly and frictionally upon the wheel 4 to keep the pawl 5 in engagement. This leads to retarding friction when winding the spring 1. In the invention, Figs. 7-9, the dome-shaped spring 18 is detachably secured to the wheel 4 by a slot 20 in the spring and a pin 22 on the wheel 4. The inner part of the spring is shaped as at 19<1>, 19<2> and when assembled the part 19<1> engages in a groove 25 in the extension 15, so that on winding the alarm spring the spring 14 and wheel 4 both remain stationary.

Filed: 1928-02-24
Abstract: 301,253. Schlayer, F. Feb. 24, 1928. Addition to 264,231. Thrashing - machines.-The thrashing and straw - reducing machine described in the parent Specification has an air inlet passage provided at the rear end of the drum 1 by making the retaining disc 49 at the end of the drum annular in shape and supporting it by short spokes 62 on a hub 63 secured to the beater shaft 6. The spokes 62 carry, or are formed to constitute, vanes 65 that force air into the drum from a hollow cylinder 66 secured to the disc 49. The cylinder 66 extends through the cap 52 and communicates through an adjustable funnel 70 with a conduit 69 communicating with the discharge pipe 67 of a delivery elevator 68. According to the position of the funnel 70 the quantity of air drawn through the conduit 69 is adjustable. A grain shoot is formed below the connection of the conduit with the pipe 67 by two plates 73, 74 between which an opening to the outer air is provided. The lower plate is adjustable to vary the width of the opening. The grain is distributed across the upper plate by a baffle 77 and falls across the opening, dust &c. being removed by the current of air. The lower part of the discharge pipe is bifurcated and the grain is directed into the one or the other portion by a valve 78. Sack-holding devices 76 are secured at the ends of the pipe. Perforations may be provided in the plates 73, 74, or these plates may be replaced by perforations in the elevator discharge pipe. Vanes 80 fitted at the rear of the disc 49 drive air rapidly to the discharge opening 81 of the cap 52. In a modification the beaters are mounted on a hollow shaft, the diameter of the shaft agreeing approximately with the diameter of the hub portion of the disc 49. The beaters 85 are secured to the shaft by devices shown in Fig. 8. Brackets 86 are secured to the shaft 84 by rivets 87. The shaft of one beater passing through an opening in the bracket is clamped against the side thereof by a wedge 93 pressed down against an inclined fan 95 on the bracket by a nut 97 on a screw 91. The end of the screw 91 also enters a socket formed on the end of the shank of the preceding beater and holds it against a projection 88 of the bracket.
