Title: Improvements relating to devices for supervising or controlling the distribution of load on the ropes of a multi-fall hoisting installation
IPC: B66B7/10
Filed: 1959-12-28
Abstract: 868,564. Electric control systems. GUTEHOFFNUNGSHUTTE STEIKRADE A.G. Dec. 28, 1959 [Dec. 27, 1958], No. 44036/59. Class 40 (1). [Also in Group XXII] In a device for supervising the distribution of load on the individual ropes of a multifall hoisting installation, friction wheels 3 are urged into the rope grooves 1 of a driving or other pulley 2 around which the ropes pass by means of weights 4, and a measure of the difference between the groove diameters of the pulley, which is a measure of any differential travel which may exist between the individual ropes, is obtained by providing each friction wheel with an electric generator, the voltage of which depends on and varies with the wheel speed and hence with the groove diameter. In a preferred embodiment a 4-rope hoisting mechanism is considered, each of the generators 5, Fig. 3, being arranged so that their voltage differences relative to one of the generators are read off on a voltmeter 6. Preferably the reference generator is that associated with the groove with the smallest diameter, in which case a circuit containing two motors may be used which is activated when the voltage difference between the reference generator and any other one reaches a predetermined value, one motor 10, Fig. 2, then causing an assembly to move so that a milling wheel 7 is urged into the groove 1 and the milling wheel is then driven by motor 8. When the diameter of the relevant groove has been reduced to that of the groove associated with the reference generator the milling process is halted. The generators are generally D.C., but A.C. generators may be adapted for use with the device.

[Also in Group XIX] A combined marking and counting instrument comprises a tubular housing 14, Fig. 1, a holder 20 having a flanged end portion 22 within the housing and a marking element 28 e.g. a pencil, pen, crayon, brush or chalk, at the other end, and a counting device 12 including a rotatable shaft 16. The shaft 16 has a cam 18 fixed thereto and the holder end 22 is held in contact with the cam by a spring 24. The counting device 12 is used as a handle and the element 28 is pressed against an object so as to make a mark thereon. Such pressure causes relative movement between the parts 14, 20, the shaft 16 is rotated and the counter 12 is advanced by one digit. On release of the pressure a spring (not shown) within the counter 12 returns the parts to the positions shown. The instrument is of particular use in production and inventory counting. In a modification, Fig. 5, a holder 32 carries a marking element 28 and is pivoted at 34 in a housing 30. When a mark is made with the element 28 the holder 32 pivots and actuates an eccentrically mounted counter trip with its rear end.

Title: Thermally responsive valves
IPC: F16K17/38
Filed: 1972-09-26
Abstract: 1373440 Fluid-pressure servomotor systems ROCKWELL INTERNATIONAL CORP 26 Sept 1972 [15 Nov 1971] 44459/72 Heading G3P [Also in Division F2]  In a fluid circuit, flow from an input line 34 to an output line 36, takes place either directly or via a heat exchanger 80, the flow-path being selected by a pressure-balanced thermallyresponsive valve member 48 co-operating with a seat 40. The valve member 48 is carried by one end of a hollow stem 52 the other end of which has attached thereto a piston 56 of dimensions similar to those of the port 42. Piston 56 has accommodated therewithin a check valve 74, Disposed about the stem 52, which is biased to the position shown by a spring 66, are bi-metallic discs 50. In the state of the valve shown substantially all flow from inlet 34 passes directly, via port 42, to outlet 36. As the temperature of such flow increases, valve member 48 is moved by the elements 50 until it engages seat 40. Thereupon, valve member 48 becomes pressure balanced consequent to the pressure forces acting on the piston 56 equalizing those acting on valve member 48. Should the inlet pressure rise beyond a predetermined value, check valve 74 opens so eliminating the pressure balance. Accordingly, valve 48 opens under a pressure differential and flow is again allowed to pass directly to the outlet 36.

A thread guiding device 13, Fig. 1, is movable from the setting shown in Fig. 1 to that shown in Fig. 2 to cause sheets 5, 6 of glass fibres issuing from a spinneret 2 to move into a plane parallel to the axis of spools 3, 4 on which the threads are to be wound. As illustrated in Fig. 4 (not shown) the thread guides are truncated rollers 11, 11amounted in the frame 13. The support column 16 has a helical groove 26 into which a pin 27 in a sleeve 24 extends to ensure that the sleeve 24 rotates when it is moved up and down the column 16. The column 16 also has a straight groove 25 into which a pin carried by a pinion 29 extends to ensure that the pinion 29 does not rotate relatively to the column 16 as it moves up and down with the sleeve 24. The resulting relative rotation between the pinion 29 and the sleeve 24 on the sleeve is moved up and down the column is used to drive a chain 30 coupled to a pinion 31 to rotate the frame 13 relatively to the arms 15,15a carried by the sleeve 24.
