Title: Improvements in and relating to Starting Switches for Electric Motors.
IPC: H01H3/32
Filed: 1917-03-26
Abstract: 112,209. British Thomson-Houston Co., and Sugden, J. March 26, 1917. Controllers with neutral position between starting and running positions.-A switch for starting electric motors by means of auto-transformers or compensators is provided with a weighted lever A which locks the operating arm B unless it is moved rapidly from the starting position to the running position. The weighted end of the lever A tends to hang vertically and the other end projects in the direction of movement from the starting position to the running position. When the arm is moved slowly, the weight causes the end of the lever A to engage a fixed stop C and prevents the arm from completing the running connexions. When the arm is moved quickly, the weight lags and causes the lever to dip and miss the stud C. In a modification, the weighted lever is connected to the arm B by a spring.

Filed: 1964-02-04
Abstract: 983,389. Yarn hank opening devices. LEESONA HOLT Ltd. Feb. 4, 1964, No. 4588/64. Heading D1J. A yarn hank opening device comprises a single drive means for moving a plurality of arms from a closed position to an open position and vice versa,characterized in that there is a common yielding element arranged to allow the arms to yield collectively when any one of the arms becomes obstructed during closing movement thereof, the drive means continuing to operate despite yielding of the arms. In Fig. 1 anti-clockwise rotation of the shaft 11 causes a collar 13, having a radial flat 14, to abut against and move a pawl 16 carried by a pinion 12. The resulting rotation of the pinion 12 rotates a plurality of further pinions 18 the pinions 18 carrying cranked arms 19 that are thus expanded apart, When the shaft 11 is driven clock- . wise, a tension spring 21 causes the pinion 12 to follow the shaft 11 with the pawl 16 pressing against the flat 14. If one of the arms 19 becomes obstructed during its closing movement it will stop and cause the other arms to stop, the pinion 12 being then held stationary against the force exerted by the spring means 21. The collar 13 continues to rotate with the drive shaft 11 but no drive is transmitted to the pinion 12.

Title: Improvements in or relating to the regulation of the flow of fluids
IPC: G05D11/13
Filed: 1937-02-17
Abstract: 490,607. Fluid-pressure servomotor-control systems. ASKANIA-WERKE AKT.- GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU. Feb. 17, 1937, No. 4818. Convention date, Feb. 17, 1936. [Classes 69 (i) and 135] In control apparatus for maintaining the fluid flows in a number of separate conduits in a desired relation, a variable throttle device such as 13 or 14 in each conduit is regulated so as to maintain the pressure difference between its opposite sides constant and the variation in the position of each throttle device is utilized to control the fluid flow in one or more of the conduits so as to maintain the desired relation. In the apparatus shown in Fig. 1 for mixing two separate fluids at substantially constant pressures in pipes 10, 11 in a mixing conduit 12, the variable orifice plates 13, 14 are operated by servomotors 17 controlled by pivoted jet pipes 22 under the control of diaphragms 21 subject on their opposite sides to the pressures on the two sides of the orifice plates by means of pipes 19, 20. The servomotors 17 also operate wedge cams 18 which through bell-crank levers 26 and springs 27 act in opposition on a third relay device of the jet pipe type which controls a butterfly or other valve 34 in one of the conduits. The relative effect of the two impulses may be adjusted by a slidable member 29 contacting the jet pipe 25 and a counter lever 28. Any discrepancies in the proportionality of the impulses to the fluid flows may be remedied by making the cams 18 adjustable or by adjusting the compression springs. Apparatus is also shown in which the flow in a conduit is controlled so that it bears a desired ratio to the sum of the fluid flows in two other conduits. Each conduit has a variable orifice plate controlled by a relay of the jet pipe type as in Fig. 1, and the impulse from the relay in the controlled conduit is balanced against those from the relays of the other two conduits which act through a floating lever. The resultant impulse operates a jet pipe relay controlling a butterfly valve as in Fig. 1. In Fig. 3, the conduits 60, 61 each have a flow meter comprising a piston valve 62 or 63 which rises in proportion to the flow so that the pressure difference between its opposite ends remains substantially constant. Armatures 64, 65 connected to the respective piston valves, when moved, disturb the balance between pairs of coils 66, 79 and 67, 70 supplied from leads 68, 69 causing sympathetic movements of armatures 74, 80 which act in opposition on a jet pipe relay controlling a valve 82 in one of the conduits. U.S.A. Specifications 1,333,986 and 1,558,529 are referred to.

Abstract: 1335497 Timing cooking ROBERTSHAW CONTROLS CO 2 Feb 1972 [3 Feb 1971] 4923/72 Heading A4D [Also in Divisions G4 and H1] A device, for determining the time for which a meat item is to be cooked at a predetermined temperature, comprises a disc bearing an outer arcuate weight scale 28 and an inner arcuate time scale 31, the disc being rotatable by a knob 26 to align the value on scale 28, corresponding to the weight of the item to be cooked, with an appropriate mark on a fixed scale 30A or 30B alongside window 29, the required time then appearing alongside pointer 33 in window 32. Scales 30A, 30B graduate types of meat and/or degrees to which it is desired the meat should be cooked. The scales may be such that the indicated time equals a constant times the square root of weight plus a factor, the latter depending on the type of meat and/or desired degree of cooking. A shaft on which the scale disc and the knob 26 are mounted, a shaft carrying hour and minute hands 84 and 83 of a continuously driven clock 24, and a gear wheel coupled to a cooking starting time hand 93 and settable by means of a knob 94 are coupled together by mechanism, Figs. 2, 4-10 and 12 (not shown), which ensures the following operational cycle:- When the hand 93 is set to a desired starting time, a flag 106 appears in window 107. When the actual time reaches the set starting time, an actuator is moved to close a plunger switch in a control circuit operative to energize the cooker heating element, and the clock mechanism is coupled to the scale disc to drive the latter backwards, so that pointer 33 in window 32 indicates the cooking time yet to elapse. At a predetermined time before expiry of the cooking time, the plunger switch is reopened to cause the oven temperature to drop from its cooking value of 325‹F. to a hold value of 170‹F. Cooking continues during the fall in temperature to 170‹F.

Title: Improvements in or relating to multi-stable circuit-arrangements comprising a cathode-ray tube
IPC: H03K21/08
Filed: 1951-03-02
Abstract: 682,297. Electronic counting apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 2, 1951 [March 6, 1950], No. 5118/51. Class 106 (i). [Also in Group XL (c)] Fig. 1 shows the circuit of a cathode-ray tube 1 which may be used as a counter or frequencydivider of a pulse train applied to lead L. The cathode-ray tube has deflection electrodes 5, 6, and collecting electrodes 7, 8, the former having apertures 7<SP>1</SP> ; the collecting electrode 8 is connected to the deflecting plate 6 so that as shown in Fig. 2 the circuit has a number of stable states at points 23-28 where the load line 22 of resistor 10 intersects the beam current/deflection electrode voltage curve 21 of the cathode-ray tube. The cathode-ray beam is caused to move from one stable position to a subsequent one by the application of a pulse to lead L. When the cathode-ray tube beam reaches the extreme left-hand position, i.e. after six input pulses have been applied, the voltage of the deflecting plate 6 is reduced by the application of the seventh pulse and the voltage of the cathode 13 of the secondary emissive valve 14 falls below that of the control grid 15. Valve 14 is thus rendered conducting and by the feed-back via capacitor 20 the valve conducts heavily, the potential at point 12 rises and the cathode-ray beam is returned to the extreme right-hand position so that the next incoming pulse applied to lead L will deflect it to its first stable position. Fig. 3 shows a modification in which the secondary emissive valve is replaced by a pair of valves 40, 47 connected in a multivibrator circuit. Normally valve 40 is cut-off and valve 47 conducting but when on the seventh input pulse the cathode-ray beam is on the extreme left-hand position and the voltage of deflection plate 6 is at its lowest value, valve 40 is rendered conducting, valve 47 is cut-off and the potential at point 12 rises to return the cathode-ray beam to its initial extreme right-hand position so that the next input pulse on lead L re-commences the cycle of operation. By adjustment of resistor 51 the cathode-ray beam may be arranged to fly-back to any intermediate stable position.
