Title: Troughed belt conveyor
IPC: B65G39/16
Filed: 1958-04-09
Abstract: 863,074. Endless belt conveyers. UNITED STATES STEEL CORPORATION. April 9, 1958 [May 13, 1957], No. 11279/58. Class 78(1). In an endless belt conveyer having a belt B carried on end rollers 6, 8, driven by a roller 12 on the lower run, and supported on the upper conveying run by sets of troughing rollers 14, each set of troughing rollers consists of five rollers, viz. a central roller 30 arranged parallel to the end rollers, and pairs of inner and outer side rollers 36, 38, the inner and outer side rollers both being inclined upwardly away from the central roller, but the rollers 36 being also inclined forwardly, while the rollers 38 or inclined rearwardly, with respect to the direction of approach of the belt. The rollers 36, 38 at each side of the assembly are carried on a single bent shaft 40, the central roller 30 being carried on a straight shaft 32. The shafts 32, 40 are mounted in brackets 34, 42, respectively, carried by the conveyer frame 4. The end rollers 6, 8, the former of which can be adjusted by tensioning screws 26, are preferably selfcentring rollers constructed as described in either Specification 735,561 or Specification 709,908, while the driving roller 12 is also preferably a self-centring roller constructed as described in Specification 709,908. A snub roller 10 is used in conjunction with the driving roller and is similar to the latter except that it is narrow-bodied, i.e. its surface engaging the belt is shorter than the width of the belt. The belt is of a width such that it normally rests on the rollers 30 and 36 of each set of troughing rollers. If the belt wanders owing to uneven loading, it engages the rollers 38 which guide the belt back into its normal path.

Abstract: 591,429. Clutches. SMITH & SONS (ENGLAND), Ltd., S., and MEREDITH, F. W. May 4, 1945, No. 11451. [Class 80 (ii)] A clutch, particularly for coupling control surfaces of an aircraft to operating servomotors, comprises members 16, 24 on shafts 13 and 20 respectively which are coupled together by balls 40 moving in radial channels 18 in the member 16 and engaging the inclined surfaces of an annual series of teeth 25 on the member 24. The balls 40 are held in engaging position by further balls 41 and a thrust plate 31 acted upon by a ring 34 and a fork 35 from a shaft 36 with an operating lever 38. The arrangement of the balls 40 and 41 is such that there is always an axial component of the force transmitted acting to move the balls 41 axially with the assistance of springs 43 to disengage the clutch. This action is opposed by a torsion spring 39 acting upon shaft 36 until disengagement is required.

Filed: 1950-02-10
Abstract: 735,515. Electronic counting apparatus. STANDARD TELEPHONES & CABLES, Ltd. Feb. 10, 1950, No. 11501/52. Divided out of 735,501, [Group XXXIX]. Class 106 (1). [Also in Group XL (c)] In a circuit comprising a plurality of eitherside-stable valve pairs arranged to count impulses on a binary basis, each impulse to be counted is fed to all the valve pairs whose state must be changed to record the impulse. By this means substantially instantaneous recording of each impulse is achieved. As shown positive impulses received over contact ae1 are applied to each of the inputs to the binary pairs T10, T11 ... T16, T17, it being arranged, however, that a pulse applied to any pair is ineffective if any of the even-numbered tubes of the previous pairs is conducting. Thus the pulse applied to T14, T15 is shunted by rectifier MR5 and tube T12, or by rectifier MR4 and tube T10 if either of these tubes is conducting, and the rectifier MR8 is thus back-biased to prevent the passage of the pulse to the pair T14, T15.

[Class 106 (ii)] One of the jaws 3 of a snap gauge can be moved slightly by a handle 6 about a pivot 5 against the action of a spring plunger 13 to increase the gap between the jaws and so facilitate insertion of the work. When the movable jaw is allowed to contact the work, the reading of a dial indicator 9 having a plunger 7 bearing on the jaw indicates the deviation of the work from the size for which the jaws are set. The other jaw 3 is normally fixed but is set by moving it about a pivot 5 by means of two adjusting screws 10 as described in Specification 577,464. The normal position of the movable jaw is defined by an adjusting screw 14. The work rests against an adjustable anvil 15. The faces of the jaws 3 may be plain or formed with a screw-thread for gauging threaded bodies. Instead of the dial indicator shown, the movable jaw may engage one arm of a bell-crank lever, the other arm forming a pointer.

Source 12<SP>1</SP> may be a transistor oscillator as shown. Inductor 17 may be the leakage inductance of a transformer. In Figs. 5, 6 (not shown), the breakdown time of gap 18 is determined by movement of one electrode closer to others, such electrodes may be part of the distributer of an I.C. engine, further transformers 16 feeding respective spark plugs.
