Abstract: 752,012. Two-part couplings. TITEFLEX, Inc. April 30, 1954 [June 28, 1953], No. 12678/54. Class 38 (1). A plug and socket coupling comprises metal shells 13, 16 housing insulating cores 36, 28 carrying pins and sockets 39, 68 respectively, the shells being held in nesting engagement with the pins engaging the sockets by a nut 17. At the rear of each core a body 47 of soft insulating material surrounds the conductors 43 connected to the contacts where they enter the core and is pressed into sealing engagement therewith by a plate 51 having tapered holes for the conductors and acted on by a spring 65 bearing on an end fitting 54. A face plate 45 recessed in the body 47 prevents the pins or sockets being drawn back into body 47. Since the cores are slidable in the shells one of the springs 65 may be omitted. The cores are located in the shells by keys 34 and slots 30, and shell 13 has a key 70 entering a slot 71 in shell 16 to ensure correct coupling of the pins and sockets. A seal is provided between the meeting faces of the cores by a resilient disc 72 with holes for the pins 39, each hole having a boss 74 around it which is compressed onto the pin when the coupling is assembled.

Title: Apparatus and method for shrinking unvulcanised tire tread strips
IPC: B29D30/52
Filed: 1954-05-03
Abstract: 750,289. Tyre-building apparatus. TRIGGS, W. W. (Goodyear Tire & Rubber Co.). May 3, 1954, No. 12762/54. Class 144 (1). An oversize unvulcanized tread strip is shrunk to the required predetermined length prior to application to a carcass on a building drum by being supported on an anti-friction surface with its ends against two relatively adjustable stops spaced at the required length and then allowed to relax, or manually patted, until its under surface contacts the anti-friction surface. The supporting surface may be a smooth board with a fixed recessed bevelled stop at one end and an adjustable undercut bevelled stop at the other end. In an alternative arrangement as shown, the supporting surface comprises a series of parallel, closely spaced, freely rotatable rollers 12 carried by side frame angle members 13, 14 mounted on an adjustable vertical support 10. A bevelled stop 16, with an overhanging tread-locating roller 23, is mounted on a cross member 19, at one end of the frame 13, 14, which is adjustable longitudinally of the frame along guides 17, 18. The other bevelled end stop 24 is carried by a cross member 25 which is mounted on arms 26, 27 pivoted to the frame members 13, 14 respectively to allow the stop 24 to be swung clear of the rollers for discharge of a shrunk tread strip thereon onto an adjacent building drum 47. A tread strip is transversely located on the rollers 12 by longitudinally extending angle members 35, 36 having screw-threaded engagement with opposed ends respectively of a pair of transverse shafts 37, 38 which are chain connected for simultaneous rotation to effect relative transverse adjustment of the locating angles 35, 36. Additionally a pair of transversely and vertically adjustable centring rollers 30, 31 are supported at the end of the frame 13, 14 adjacent the stop 24 to contact the sides of the hump of the tread strip as it is fed to the drum 47, the two end rollers 12<SP>1</SP> and 12<SP>11</SP> being mounted in the frame 13, 14 for slight axial displacement against end compression springs 50 to provide for any misalignment of the tread with the carcass on the drum 47.

Abstract: 876,181. Resilient couplings. TETLOW, N. Jan. 26, 1959 [April 23, 1958], No. 12834/58. Classes 80 (2) and 80 (3). A flexible coupling is provided with intermediate members between the driving and driven elements and engaging resilient means which produces a couple resisting that due to the applied torque. As shown in Fig. 1, the intermediate members 20 are cruciform, one pair of arms 23, 25 engaging blocks of rubber 24, 26, preferably precompressed, in the driving and driven elements 21, 22, while the other pair of arms 27 engage rubber blocks 28, 29 in the annular space between members 21, 22. In operation, rotation of members 20 due to the driving torque is opposed by the couple set up by deformation of the blocks 28, 29. In a second arrangement, Fig. 5, the elements of the coupling are connected by T-shaped links 50 through pins and rubber bushes 54, 55, 56 providing the desired flexibility. In a modification of this construction, Fig. 7 (not shown), the single arm of each link is reversed to lie near the outer periphery, while in a second modification, Fig. 10 (not shown), the links are arranged tangentially around the circumference of the driving and driven elements. The resisting couple may also be furnished by a spring ring, Fig. 11 (not shown), or by a rubber annulus, Figs. 14 and 16 (not shown).

Abstract: 1,240,044. Measuring denier of yarn electrically. TEIJIN Ltd. March 11, 1969 [March 11, 1968 and March 14, 1968], No. 12881/69. Heading G1N. [Also in Division G4] In apparatus for measuring the denier of yarn pressure air is applied to nozzles 2 forming a yarn passage, changes in back-pressure causing a bellows 3 to vary the capacitance of a capacitor formed by a spring plate 6 attached to the bellows and a plate 6<SP>1</SP>, the capacitor being connected in an oscillator whose frequency change is measured by analogue or digital means. The plate 6 is fixed at at least two points symmetrical spaced from the point of attachment 5<SP>1</SP> to the bellows 3. The output of the oscillator may be compared with a reference in a mixing circuit whose output is differentiated to produce pulses which may be fed to a counter or computer. These pulses may, alternatively be applied to a monostable multi-vibrator and a rectifier to produce an analogue signal. In afurther alternative the oscillator output may be fed to a limiter and a discriminator to produce an analogue signal. In a zero method for measuring sampled specimens of yarn, a micrometer screw is attached to the plate 6<SP>1</SP>, a rotor mounted on the screw being rotated to bring the spacing between the plates 6, 6<SP>1</SP> to its original thus the analogue output to its original level.

Abstract: 1,203,018. Sterilizing liquid containing solid particles. ALLIED CHEMICAL CORP. 11 March, 1969 [10 May, 1968], No. 12882/69. Heading A2D. Liquid containing suspended solid, discrete particles is sterilised by heating a substantial part of the liquid free of discrete particles to 250F. to 330F. to sterilise this liquid and raise its temperature above that required for sterilisation, metering the particles into the sterilized liquid and holding the combined sterilised liquid and particle mixture at a temperature in said range for 1 sec. to 5 minutes to allow for sterilisation of the particles by the sterilised liquid. The particles have a maximum linear dimension of about 1¢ inches. A back pressure may be maintained on the sterilised mixture of liquid and discrete particles so as to move the mixture gently through the particle sterilisation step. The sterilisation of sour cream containing chives, and milk containing diced carrots, is exemplified.

The sequence of passes is alternately oval and square. To roll small section wire or band iron, a zigzag formation of mill is used, e.g., by putting the roll pairs 2, 3<1> and 4 out of action, the work then being rollled in sequence in roll pairs 1, 1', 2<1>, 3, 4<1>. For rolling iron rods for making screws the rows of stands 1, 2, 3, 4 and 1<1>, 2<1>, 3<1>, 4<1> are spaced sufficiently far apart to allow a loop to be formed so removing tension in the work. The loops formed render unnecessary a workman for guiding and turning square section wire.
