Title: Improvements in or relating to maximum demand electric supply meters
IPC: G01R11/60
Filed: 1936-11-20
Abstract: 474,551. Supply meters. WESTING- HOUSE ELECTRIC & MANUFACTURING CO. Nov. 20, 1936, No. 31777. Convention date, Nov. 29, 1935. [Class 37] In a maximum-demand electric supply meter of the type in which the maximum consumption of energy during periodically recurring intervals of time is recorded by a pointer 12, Fig. 1, which is moved on by a driving member 20, periodically react to zero, the driving connection to the member 20 is interrupted to permit such periodical resetting by means of a cam member 72, Fig. 3, driven by a timing mechanism at a predetermined speed and a second member 62 driven by the same mechanism, but at a lower speed, this member 62 carrying a cam surface 68 adapted to be engaged by a cam surface 74 on the member 72, one such engagement being arranged to occur at the instant when the parts 68, 74 are opposite a member 80 which is thereby moved to break the driving connection. The pointer 12 is frictionally held in its displaced position by a spring clip 16 which also acts as a stop and the member 20 for advancing the pointer is fixed to a sleeve 22 which is carried by a shaft 25 and is biassed to its initial position by a spring 28. The sleeve 22 is widened at one end, this end cooperating with a resilient pad secured to a gear 24 and pressed against the sleeve by a spring 36 to form a friction clutch. The gear 24 is secured to a sleeve 34 slidable along the shaft 25 and is moved to release the clutch by a pivoted lever 45 which carries the part 80. The members 62, 72 are in the form of coaxial discs driven through a one-way clutch by a synchronous motor 50 through suitable gearing, the disc 72 rotating twelve times as fast as the disc 62. The cam surface 68 is carried by a lever 64 pivoted to the disc 62 so that when the surfaces 68, 74 engage, a part 66 of the lever is projected beyond the edge of the disc. This is arranged to occur once when opposite the part 80 and then causes the lever 45 to move about its pivot and force the sleeve carrying the gear 24 along shaft 25 out of engagement with the sleeve 22, so that the member 20 is returned to its initial position against the stop 16 by the spring 28.

Title: Improvements in or relating to clutch controlled devices for the transmissions of self-propelled vehicles
IPC: F16D48/02
Filed: 1949-12-16
Abstract: 675,229. Operating clutches. LIVERMORE, W. T. Dec. 16, 1949 [Jan. 29, 1949], No. 32328/49. Class 80 (ii). The engagement pressure of a fluid-operated friction clutch of a vehicle is controlled in accordance with both the position of the accelerator pedal and the speed of the engine. A clutch engaging piston or diaphragm 10 is subjected to pressure from an engine driven pump 11 under control of a pressure regulating device 21, 25. This device comprises a valve 25 loaded by a spring 26 and fluid pressure in a chamber 23 and co-operating with a seating 27 and a piston 21 acted upon by a spring 22 and controlling ports 20 in the valve member 25. The pressure in the chamber 23 is controlled by a control valve 29 according to the loading of a spring 31 thereof by the vehicle accelerator pedal 30. In operation with the engine at idling speed the pump 11 supplies pressure fluid past a pre-load valve 16 to a chamber 19 in communication with the diaphragm 10 where it acts on the valve 25 to lift it from its seat 27 against spring 26 and escapes to an exhaust passage 120. The pressure of this fluid is insufficient to overcome the clutch release springs, On a depression of the accelerator pedal pressure fluid is supplied to the chamber 23 to increase the loading on valve 25 and move it towards its seat 27 which results in an increase in pressure in the chamber 19 and acting on the diaphragm 10 to engage the clutch and load it in accordance with the accelerator pedal actuation. The spring 22 acting on piston 21 is sufficiently strong to prevent the ports 20 opening up to a certain value of the clutch actuating pressure but when this pressure is reached these ports open and the valve 25 seats onto the seating 27 so that further increases in engine speed result in increase of the pressure loading of the clutch in proportion to the square of the engine speed. The maximum clutch loading is always dependent however on the pressure in the chamber 23 controlled by valve 29. The range of accelerator control can be varied by varying the strength of spring 22 and can be eliminated altogether if desired so that the clutch pressure varies with the engine only. The clutch pressure may be maintained at a higher value under certain conditions of low engine speed and when using the engine as a brake by means of a plunger 35 which is adapted to hold the piston 21 in a position closing the ports 20 so that a higher pressure is maintained in chamber 19 and on the diaphragm 10. The plunger 35 could be actuated by a member moving in response to certain higher speed ratios. Specification 632,562 is referred to.

Title: Improvements in bobbin stripping machines
IPC: B65H73/00
Filed: 1931-11-23
Abstract: 380,997. Bobbin stripping machines. TERRELL, E. A., 1200, North Church Street, Charlotte, North Carolina, U.S.A. Nov. 23, 1931, No. 32439. Convention date, Aug. 21. [Class 120 (iii).] In bobbin stripping machines of the type in which the bobbins are fed by an arcuate guide protected by an arcuate guard and in which stripping is effected by endwise movement of the bobbin relatively to a stripper device, improved means for accurately positioning the bobbin adjustable for different size bobbins comprises, firstly, adjustable means for supporting the bobbin tip immediately above its stripping position, secondly, means independent of the guard strip for positioning the bobbin longitudinally which means yields under the stripping action, and thirdly, convergently adjustable means adjacent to the stripping blade supports which co-operate with the second mentioned positioning means, to locate the bobbins longitudinally by engaging the shoulder of the bobbin head. The bobbins to be stripped descend in the arcuate guide 2, the heads being guided by rails 4 and prevented from overlapping by a guard 150 which may be rigid as shown or pivoted at its upper end and retained in place by a spring. The bobbin tip is supported immediately above stripping position by the curved ends 66 of two adjustable pivoted arms 65, Fig. 4, which may be weighted as at 75, or spring-loaded as at 72. The bobbin is displaced by a plunger (not shown) and is received by the push-head 14 which forces the bobbin through the stripping means, the movement being completed by pulling grippers which engage the bobbin head. Instead of the pivoted arms 65, the bobbin tip may be supported by a pair of fixed spring arms, adjustably mounted in the side walls 2. The means for positioning the bobbin longitudinally comprise a pivoted extension 45 of the guard 150, provided with a spring 48 and bobbin engaging face 47 ; the extension yields to allow the passage of the bobbin during stripping. The pivoted extension 45 may be replaced by a long finger overlying the guard and pivoted independently of the guard near the top thereof. A further means for positioning the bobbin longitudinally, which co-operates with the above described means comprises flanges 88, Figs. 12, 13, and 17, having inclined bevelled inner ends 95, formed integrally with the plates 87. The cover-plates 87 enclose the guideways for the two pairs of reciprocating stripper blades 91, 92, and are mounted by means of slotted bolt holes 89 so as to be capable of adjustment to suit different diameter bobbins. The bobbins drop in between the bevelled ends 95 of the flanges 88, said bevelled ends being adapted to abut against the bobbin head. Alternatively, each complete guide block 81, 82 together with its flanged cover-plate 87 may be mounted so as to be capable of adjustment as a unit towards and away from the bobbin being stripped. Specifications 325,494, 325,496, 325,497, 325,498, 326,530, 326,810, and 326,811, [all in Class 120 (iii), Yarns &c.], are referred to.

Convention date, April 4. [Class 40 (iii)] In a superheterodyne receiver interference at the image frequency is suppressed by an uncoupled inductive impedance Y connected between the antenna circuit A and the common point between an inductance 2 and a condenser 6 which form a shunt branch of a tuned secondary circuit. In a modification, Fig. 2, the suppression circuit comprises a condenser Z connected to the common point between two series condensers which form a shunt branch of a tuned secondary circuit. A second image suppressing circuit may be used additionally comprising the condenser X between the terminal A and the high potential end of a tuned secondary circuit. Fig. 1 shows the application to a band-pass filter in which the condenser 6 forms the coupling between the two circuits and condenser C prevents low frequency disturbances from reaching the grid 13 of the valve. When two image suppression circuits are used one may give optimum suppression at 250 and the other at 550 metres in a receiver operating over the range 200-600 metres.
