Abstract: 1,217,536. Texturising yarns. GLANZSTOFF A.G. 31 Jan., 1968 [1 Feb., 1967; 16 March, 1967; 19 June, 1967; 14 Dec., 1967 (2)], No. 4887/68. Headings D1F and D1W. A fluid jet for interlacing the filaments or fibres, without forming loops, of one or more yarns comprises a yarn duct, a fluid inlet opening into the duct, and a resonance chamber opposite the inlet, the sum of the width of the duct and the depth of the chamber being at least 2.2 times the smallest cross-sectional dimension of the chamber. The axis of the inlet and chamber may be perpendicular to, or form an obtuse angle to the axis of the yarn duct. The yarn duct may flare outwardly towards the yarn entry, or the inlet portion may be of greater cross-section than the outlet portion the transition between the two portions occuring downstream of the fluid inlet. The fluid inlet may contain one or more helical inserts to form the fluid stream into two or more whirling streams. There may be more than one fluid inlet. The jet may be formed as an insert in an arm pivotally mounted on an air supply pipe and having a bore connecting the fluid inlet to an aperture in the pipe in one position of the arm. It is stated that the. interlaced yarn has knots which in contradistinction to the prior art are not sharply delimited.

Abstract: 912,538. Lubricators &c. GAMET PRODUCTS Ltd., and PRATT PRECISION HYDRAULICS Ltd. Feb. 12, 1960 [Feb. 12, 1959; Dec. 31, 1959], No. 5042/60. Class 12 (3). [Also in Group XXII] Rotary - spindle headstock assembly comprises an outer stationary annular member having spaced internal rollerbearing surfaces and three inner rotary members fixed in relation to the spindle, two of the inner members having external roller bearing surfaces between which the third inner member is arranged to co-operate with a central part of the outer member to form a rotary distributer for pressure oil. The rotatable spindle 1 has a driving gear 50 keyed thereto at one end and a chuck 26 secured to a flange 1a at the other end by screws 27. The chuck has radial jaws 40 operated by bell-crank levers 38 which are pivoted by axial movement of a sleeve forming part of a double-acting piston 30 moved by oil pressure in a cylindrical bore of the chuck body. The spindle 1 is supported by two sets of tapered roller bearings 3a, 3b, the outer bearing for which consists in a sleeve 3 forming a stationary part of a distributer for oil pressure operating the chuck. A corresponding sleeve 6 secured to the spindle forms the other part of the distributer, there being a small clearance of the order of one to twohundredths of a millimeter between the rotating and non-rotating surfaces.

Patent GB-1010157-A (GB)
Title: Playback apparatus for use with sound records of the embossed type
IPC: G11B3/36
Filed: 1964-02-06
Abstract: 1,010,157. Playback of embossed records. DICTAPHONE CORPORATION. Feb. 6, 1964 [Feb. 26, 1963], No. 5102/64. Heading G5R. To prevent a playback stylus from attempting to play back the land raised between adjacent grooves in an embossed belt record, the stylus support is provided with a head mounting permitting further movement of the stylus after it has engaged the record, and a mechanism responsive to the further movement to shift the stylus transversely into a groove. Referring to Figs. 1 and 5 the playback head 12 is mounted in a pair of forked arms 52 extending from a vertical support plate 50 attached to a flat spring 48 which is riveted to a vertical support bracket 44. The bracket 44 is rotatably mounted by a high viscosity silicone bearing (not shown) on a shaft 42 extending from a support arm 22 which is pivoted by a screw 26 to a part 28 of a movable carriage 20, the arm 22 being biased clockwise by a spring 30. The stylus 14 may be disengaged from the record 16 by means of a slide 40 adapted to engage a finger 36 of a rigid wire 32 and thereby rotate arm 22 anticlockwise. A horizontal guide bar 60 is centred by a centering device 60 thereby centering the stylus with respect to the shaft 42. When the slide 40 is moved back, the stylus is moved into contact with the record by the spring 30, and if it engages a land between grooves the force of the spring 30 acts against the flat spring 48 and continues to move the bracket 44, the further movement being accommodated by the lost motion connection comprising the pin 56 extending through slot 58. As a result of this further movement the support plate 50 is, in effect, rotated about the riveted side 46 of the bracket, thereby moving the stylus laterally into a record groove. Any excess lateral movement is absorbed by movement of the bracket 44 about the silicone bearing, and if the stylus initially contacts a groove the bracket 44 will rotate as the resistance of the bearing is less than the resistance of the stylus against the side of a groove. Specification 1,010,156 is referred to.

Title: A process of manufacturing sulphamic acid
Inventor: CLAUSON-NILS KONRAD FRIEDRICH
IPC: C01B21/093
Filed: 1959-02-13
Abstract: Sulphamic acid is prepared by reacting urea, H2SO4, and SO3 in suspension in a halogenated hydrocarbon, preferably an aliphatic hydrocarbon having 1-6 C atoms, e.g. tetrachloroethane, or tri-, or tetra-chloroethylene. Stoichiometric quantities of reactants may be used, or an excess of not more than 5% of H2SO4 and/or SO3, which may both be present in the form of oleum, e.g. 40-45%.  The urea should be added in portions so that the temperature is 40 DEG -50 DEG C. for the first half of the addition, and 50 DEG -60 DEG C. for the second. When the urea addition is completed after say 1-2 hours the temperature is raised to 90 DEG -110 DEG C.  The mixture is stirred throughout, and finally cooled, when the balls of sulphamic acid (0,5-1,5 mm.) are separated by filtering or centrifuging.  The sulphamic acid is dried in an air stream at 100 DEG C., and the mother liquor may be reused after regeneration, if necessary, by water washing and distillation.

Abstract: 347,356. Coin-freed article delivery apparatus. BARKER, R. W., 56, Ludgate Hill, London. -(Lamson, J. ; 41, East 42nd Street, New York, U.S.A.) Feb. 17, 1930, No. 5241. [Class 27.] Articles stored in piles; storage.-In a vending machine the packets A are supported on a carriage attached by a 'cable 6, Figs. 1 and 2, passing over a guide 6<1>, to a drum 8. When a shaft 15 is rotated by a handle, a crank 16 through a link 45 and ratchet drive rotates the drum to raise the pile, until the topmost article is clear of a front plate 55, which has a downwardly inclined delivery shelf 56. At the same time, a pin 17 on the crank 16 works in a slot 18 of a front bar 19 connecting two arms 20 which form the short arm of a bell-crank lever 20, 22. In a complete throw of the crank 16, the bell-crank lever moves a slider 36 from the front to the rear of the machine and back again, the slider moving between the sides 24, 24<1> of a pivoted frame which is held down on the packets by a catch 29<1> on a vertical rod 28 controlled bv a spring 35. The slider has mounted thereon an L-shaped presser 40 which is pressed down by a spring 41 to engage behind the topmost packet, raised as described, and push it off the pile for delivery. This delivering mechanism forms the subject-matter of Specification 347,572. The link 45 is connected to a rocker arm 46 having a driving pawl 47 for rotating the drum 8. The pawl is normally held out of engagement with ratched teeth 48 on the drum by a spring 50 until it is engaged by a cam 53 on the end of a rocker arm 34, which has a pin 33 engaging a slot 32 in a lateral extension of the rod 28. The thickness of the packet determines the movement of the rod 28 and thereby the position of the cam 53 so that the feed of the drum 8 at each actuation corresponds to the thickness of the packet. Reverse movement of the drum is prevented by a pawl 65, which is held out of action, when the machine is being refilled, by a rod 68. The rod 68 is held raised by a catch portion 68<1> hooking over a shoulder 29<11> on the catch 29<1>. The front plate 55 is adjustable in height to suit the packets by teeth 59 thereon engaging pins 57 on a bar 581, the plate 55 being frictionally held by a hump 62 on a rod 60 passing through the bar 58<1>.
