Title: Improvements in the production of crimped yarns
Inventor: FITTON SYDNEY
IPC: D02G1/02
Filed: 1961-08-23
Abstract: A crimped continuous filament yarn is obtained by subjecting a yarn which is molecularly stabilized to a first molecular modifying treatment under such yarn tension conditions as to shrink the yarn longitudinally, molecularly stabilizing the yarn at least in part, and then crimping it and setting the crimp.  The yarn may be shrunk longitudinally by a heat treatment in which the yarn may contract by up to 5%, or by using an appropriate swelling agent -for example phenol or alcohol-the agent being removed by rinsing or evaporation before the yarn is crimped.  The heating step and the heat setting of the crimp may be carried out by hot air, steam, radiation or dielectric heaters, or by contact with a hot surface.  Alternatively the crimp may be set using a swelling agent.  The yarn may be composed of thermoplastic material-e.g. polyester or polyamide-or of cellulose.  In the embodiments of Figs. 1-8 (not shown) a yarn is passed successively through a heater, a cooling zone, twist stop, the first heater again or a separate heater, and a false twist tube. Alternatively the process may be carried out in discrete steps, and/or the yarn may be edge crimped or stuffer-boxed crimped.

Title: Improvements in or relating to liquid pressure transmission system
IPC: F15B7/00
Filed: 1953-11-05
Abstract: 743,517. Telemotor systems. SPERRY PRODUCTS, Inc. Nov. 5, 1953 [Dec. 4, 1952], No. 30603/53. Class 69 (2). In a telemotor system, the transmitting and receiving units T, R respectively can be synchronized to counteract temperature changes and leakage without altering the position of the operated member. Each unit comprises a casing 16, 16<SP>1</SP> containing a piston 11, 11<SP>1</SP> in a cylinder 10, 10<SP>1</SP> connected to a lever 14, 14<SP>1</SP> carried by a shaft 17, 17<SP>1</SP>, and each lever is loaded by a spring 22, 22<SP>1</SP>. A pipe C connects the units, and an operating handle 15 and an operated member 15 are provided on the shafts 17, 17<SP>1</SP>. To synchronize the units, a plunger 70 is depressed closing contacts 66, 67 thereby energizing a solenoid 64 which moves members 60 to clamp the shaft 17<SP>1</SP> against rotation. The handle 15 is then moved clockwise (in Fig. 1) moving the piston 11. Since shaft 17<SP>1</SP> is clamped, piston 11<SP>1</SP> cannot follow the movement of piston 11 and suction is created in the pipe C. This suction allows a plunger in a cylinder 54 to be moved by a surrounding spring to disengage a detent in the shaft 17<SP>1</SP> freeing the lever 14<SP>1</SP>. With continued movement of the handle 15 to its extreme position, a projection 40 on the handle strikes a lever 42 and a valve 47 is opened allowing liquid to pass from the pipe 3 into the casing 16 or vice versa. At the same time, the piston 11<SP>1</SP> descends and the arm 141 rotates. The handle 15 is now moved counterclockwise and levers 14, 14<SP>1</SP> rotate until the detent engages and the lever 14<SP>1</SP> is locked to the shaft 17<SP>1</SP>. The shaft 17<SP>1</SP> is unclamped by the release of the plunger 17. Specifications 419,310, 516,752 and 540,911 are referred to.

Abstract: 744,284. Connectors for tubes. BOULTON TUBULAR STRUCTURES, Ltd. Feb. 3,1955 [Nov. 11, 1953], No. 31197/53. Class 99(1). Tubes 15, 16 are secured in coaxial alignment by a connector comprising a tubular body divided longitudinally into two substantially symmetrical members 1, 2, a collar 3 surrounding the body intermediate the ends thereof, and a bolt 5 which passes freely through and radially of the collar, between two adjacent edges of the members and into engagement with a nut or equivalent tapped member 7 housed internally of the body. By rotating the bolt in the appropriate direction the free end of the bolt shank passes between the members 1, 2 at or in the vicinity of the opposite two adjacent edges of the members thereby separating those edges and expanding the body. As shown, the members 1, 2 have tapered ends and are of angle cross-section, the flanges being of unequal depth and the angle between the flanges being about 60 degrees. The shallower flanges are arranged edge-to-edge, and the deeper flange of each member is formed with an internal bulge 9- and an internal depression 8, the latter being engaged by the adjacent edge of the nut 7 and the bolt 5 passing through a hole 4 in the collar 3 which is in abutment with the ends of the tubes 15, 16. The member 1 has a projecting dovetail tongue 10 loosely engaging in a corresponding dovetail recess 11 in the member 2, and the recess is flanked by projecting ears 13 loosely fitting in pockets 12 flanking the tongue. An aperture 6 formed partly in the tongue 10 and partly in the base of the recess 11 has a diameter greater than that of the bolt 5 and chamfered portions 14 to permit relative rocking movement between the members 1, 2 about the abutting edges thereof. Rotation of the bolt 5 in a direction to abut with and rise over the bosses 9 causes the free edges of the deeper flanges to separate. The internal diameter of the collar may be greater than the internal diameter of the tubes 15, 16, and the interengaging tongue and recess may be of uniform and equal widths, the ears and pockets being wedge-shaped. The free end of the bolt shank may be of frusto-conical shape, the surface of the bosses 9 being correspondingly inclined.

Title: Improvements in disc talking machines
IPC: H04R7/00
Filed: 1922-11-15
Abstract: 207,980. Gramophone Co., Ltd., and Buckle, H. L. T. Nov. 15, 1922. Reproducers, arrangement of and supporting.-Relates to sound-reproducing machines in which a diaphragm-holder is carried by an arm which is pivoted to allow the diaphragmholder to swing in a direction parallel to the plane of the record, the holder being so pivoted at the free end of this arm that it can be tilted up away from the record. According to the invention, which is especially applicable to machines in which the diaphragm is large, the vertically swinging member, which allows of the tilting, is a plate or rigid frame on which the diaphragm-mounting is pivoted. The diaphragm 13 is mounted in a rim carried by a spider 19, across which is fixed a flat bar 21 with turned-down ends 22. Pivot-pins 24 engage in holes in the parts 22, the pins being carried by a rigid frame 10 which is pivoted at 6, 6 to an arm 3, itself mounted between pivots 4, 5 so as to permit of swinging in a direction parallel to the plane of the record. Lugs 8 on the arm 3 are adapted to engage fixed stops 9 to limit the swinging movement of the arm. The downward movement of the member 10 is limited by an adjustable stop 14, and the upward movement by abutments 17, 18. To regulate the pressure of the stylus on the record, the weight of the diaphragm-holder is compensated for, to any desired extent, by a coiled spring, which is secure at one end to one of the pivotpins 24, and at the other end to a barrel. This barrel can be turned by a knurled head 27, to tension the spring as required, and then clamped to a member 28 which transmits the force of the spring fo the spider 19 bv engaging a pin on the bar 21. Where the mechanism is mounted upon a sloping motor-board 1. as shown, a spring plunger 33 is provided to act upon the rear face of the arm 3, in order to compensate for the tendency of the arm to gravitate sideways.
