Title: Improvements in and relating to a roller bearing device for helicoidal movement
IPC: F16C31/04
Filed: 1957-02-25
Abstract: 819,978. Roller bearings. STRANDGREN, C. B. Feb. 25, 1957 [March 6, 1956], No. 6193/57. Class 12 (1). [Also in Group XXIV] In a roller bearing comprising ribbed rollers 19 disposed between and engaging an inner ribbed member 17 and outer ribbed members 5, 6, the ends of the rollers being provided with straight gear teeth 21, 22 engaging straight gear teeth 8, 11 on the outer members 5, 6, the profiles of the ribs of the rollers 19 and the outer members 5, 6 are formed of arcs of circles whose radii s, S are proportional to the number of ribs on the rollers 19 and the number of ribs on the outer members 5, 6 respectively. The ends of the rollers 19 are also provided with journal portions 23, 24 mounted in cage rings 25, 26 respectively. The ribs on the rollers 19 and members 5, 6 have the same angle of inclination p with respect to a radial plane whereas the ribs on the member 17 have an inclination q with respect thereto. The outer members 5, 6 are mounted in a cylindrical housing 1 having an annular end wall 2 at one end and a screwthreaded adjusting ring 13 at the opposite end. The ring 13 is adapted to be locked in position by tightening screws 15 which deform the slotted periphery of the ring 13. A resilient ring may be interposed between the ring 13 and the member 6 to take up play. In a modification, straight teeth 43 on the ends of rollers 36 mesh with straight teeth 44 provided on a screw 37, Fig. 7, the threads of the rollers 36 having the same inclination as the threaded portions 30, 31 of the screw 37. In this case, the rollers 36 participate in the longitudinal movements of the screw 37. The threaded portions 30, 31 are keyed to the screw 37 and their relative axial positions are adjustable by means of a nut 41 screwed on the end of the member 37. Specification 699,410 is referred to.

Abstract: 642,116. Endless-belt conveyers. SOMERS, F. G. C. March 5, 1947, No. 6296. Convention date, March 5, 1946. [Class 78 (i)] [Also in Group V] An endless belt conveyer 12 of stainless steel is driven intermittently by a constantly-driven electric motor 16 through a combined clutch 17 and brake 18 which are operated by a lever 22 pivoted at 23 and connected to the clutch and brake at 24. The lever is normally pulled away from the motor by a spring 28, the clutch being then disengaged and the brake applied. To remove the brake and engage the clutch a solenoid 32 is energized by a timer, thus operating valve 29A to admit compressed air to cylinder 30 and move piston 26 and associated lever 22 towards the motor.
Patent GB-996089-A (GB)
Title: Improvements in or relating to methods of preserving blood
IPC: A61K35/18
Filed: 1963-02-15
Abstract: Stored erythrocyte suspensions, particularly blood, are preserved by removal or interception of the red corpuscle intracellular metabolic products.  Deterioration of the red corpuscle is measured by the degree of lactic acid development. The preserving procedure may involve setting up a high diffusion gradient between the interior of the erythrocytes and a surrounding liquid, e.g. the suspension may be held in a semi-permeable membrane within a saline buffered at pH 7.4 and containing glucose and phosphate.

Title: Improvements in the crimping of textile yarns or threads
Inventor: BEECH SAMUEL ROBERT
IPC: D02G1/02
Filed: 1955-03-04
Abstract: 784,004. Finishing yarns; thread guides and tensioning arrangements. FINE SPINNERS & DOUBLERS, Ltd. March 5, 1956 [March 4, 1955], No. 6397/55. Classes 120(2) and 120(3) In " crimping" yarns or threads of synthetic or artificial thermoplastic e.g. polyamides and polyesters, fibres or filaments, two (or more) such yarns are passed continuously through a heating zone to. and from which they are separately directed by two sets of individual guides between which the yarns are continuously twisted together and continuously  untwisted without the use of any mechanical twisting mechanism; the deformations imparted to the intertwisted yarns are set in the heating zone. As shown in Fig. 2, yarns a and b wound together on a bobbin A, are passed between the prongs of a trident-shaped guide C within a vessel of oil at a temperature of approximately 220‹C., the yarns are rotated e.g. 960 turns, by means of a temporary clamp, and the ends then passed through guides e and f and (under a regulated tension) to receiving packages E and F frictionally driven by cylinders E<SP>1</SP> and Fl; in threading up the apparatus and in order to effect the initial rotation of the yarn, the yarns may be passed through two separate holes in a wheel located at X. In apparatus, Figs. 3 and 4, for compensating for different contractions in the yarns a and b as they pass through the heating zone, the yarns are drawn through forks a<SP>1</SP> and b<SP>1</SP> on a T member H, pivotally mounted at h, by driven conical drums K and cylinders K<SP>1</SP>; the twisted portion passes over an electrically heated metal plate B<SP>2</SP> and through a fork c<SP>1</SP> on the member H and the separated yarns e and f are taken up on bobbins E and F driven by cylinders E<SP>1</SP> and F. If the point g moves to one side, the twisted yarn moves the fork c<SP>1</SP> in the same direction so that the member H rotates and the forks a<SP>1</SP> and bl lead the incoming yarn to parts of the drums K having a larger diameter in one case and a smaller diameter in the other: the resulting difference in yarn speeds restores the point g to a central position. Specification 762,475 is referred to.

Title: Improvements in or relating to Sewing Machines.
IPC: D05B73/08
Filed: 1916-03-18
Abstract: 106,459. Jerram, A. E., and British United Shoe Machinery Co. March 18, 1916. Boot-sole sewing-machines ; rotary horns; starting and stopping gear. -- In a sole-sewing machine of the type having a rotatable horn carrying a looper for threading a barbed needle which penetrates the work from the side of the work opposite to the horn, the horn is arranged so that it can be moved laterally into and out of sewing position without producing such disconnexion of the mechanism for actuating the looper as permits variation of the timing. The horn 16 is supported on a bracket 20 pivoted on bearings 22 across the machine. The axis of these bearings is a tangent to the bevel-wheels 17, 18 which drive the looper. A locking-bolt 25 movable by the treadle 44 co-operates with the projection 27 to hold the horn in or out of sewing position. The treadle 44 is provided with a pawl 48 which engages either the pin 40 on the lever 39 or the pin 37 on the lever 36 according to whether or not the plate 50 on the treadle is pushed forward by the operator. The lever 36 controls the clutch. The lever 39 is connected by a rod 35 to a hellcrank 32 with a cam which controls the bell-crank 37* connected to the presser-bar-lifting mechanism through the rod 39*, and also to the horn-locking bolt 25. The horn may be moved by a spring away from the working position, or may be moved by linkage connected to the horn-locking and presser-foot mechanism and having means, as a toggle-link, which enables the machine to be run when the horn is out of active position, if necessary. Specifications 15756/12 and 19211/90 are referred to.
