Title: Improvements in or relating to electric metering apparatus
IPC: G01R11/56
Filed: 1936-05-20
Abstract: 475,512. Supply meters. MERCER, R. (Sangamo Electric Co.) May 20, 1936, No. 14299. [Class 37] A maximum demand electric supply meter having means for determining the maximum demand comprising a member advanced during a time interval in accordance with the maximum demand during that interval is provided with integrating mechanism which is operated in unison with this member for recording the summation of each of the maximum demands of a number of these tune intervals. The meter motor shaft 1 drives a worm shaft 4 through a worm wheel 3, which is fixed on the shaft and is adjustable relatively to the shaft 1 by supporting one end of the shaft 4 in a bracket which is slidable on a post 5, being adjusted by means of a screw fixed to the bracket and engaging on a fixed supporting plate 7. The shaft 4 drives through suitable gearing a shaft 18 which carries the units indicating-member 24 and which also drives through the usual gearing other pointers 27, 28, 29, all of which move over dials in the known manner of integrating watt-hour-meters. Further pointers 33, 34, 35, moving over suitable dials, show the integrated maximum demand, and a pointer 36 shows the actual maximum demand for a single period. The pointers 35, 33 are driven at appropriate rates from a sleeve 41 to which is fixed the pointer 34, and the pointer 36 is fixed to a shaft 44, Fig. 5, upon which is rotatably mounted the sleeve 41, the sleeve 41 and shaft 44 being frictionally clutched together by a spring washer 46. A sleeve 50, which is driven from the gear train operating the usual integrating mechanism, is adapted to be clutched frictionally by a spring 51 to a second sleeve 47 which is freely rotatable on its shaft, but is provided with an arm 48, adapted to actuate the maximum demand mechanism. The shaft 44, and with it the pointer 36 and sleeve 41 for driving the maximum demand integrating mechanism, are moved by the engagement of the arm 48 with a projection 45 fixed to the shaft, the arm 48 being returned at regular intervals to its initial position against a stop 351 by the operation of a weight 49, when the spring 51 is compressed. The compression of the spring is effected by a pivoted lever 75 which is moved downwards at the required times by means of a rotating cam on a shaft 69 and a lug also carried by a rotating member. The cam and lug move at suitable speeds, being driven by a synchronous motor 621, such that at intervals the sleeves 50, 47 are separated for a short time to permit the arm 48 to return to zero, but the pointer 36 and maximum demand integrating mechanism remain in their displaced positions. The pointer 36 and the connected arm 45 however can be manually pushed back to the zero position but the integrating mechanism is not returned, being held against backward movement by a pawl and ratchet mechanism.

Title: Improvements in or relating to automatic control means for electrically driven tools
IPC: B44B3/06
Filed: 1936-05-21
Abstract: 477,085. Electric control systems. PHOTO SCULPTURE, Ltd., and JEFFREYS, S. T. May 21, 1936, No. 14382. [Class 40 (i)] In a system for controlling a machine tool in accordance with an outline placed on a control screen, the outline is produced by insulation placed on a conducting surface and a tracer contact co-operates with the surface in such a manner that the circuit of a motor is intermittently made and broken to control automatically the position of the tracer and the tool. As shown, a cutting tool 13 and a tracer contact 67 are carried on a table 64 slidable along guides in one or other direction by a threaded rod 65 driven through reversible clutch mechanism 41, 42, 62 by a constantly running motor 53. The table 64 is mounted on a second table 61 which is driven in a direction at right angles to the direction of motion of the tool by a motor 19. The arrangement is such that when the contact 67 engages the conducting portion 39 of the control screen, the clutch mechanism is operated by one of the magnets 43, 44 to drive the tool to the right until when the contact co-operates with the insulating outline 2b the control circuit is broken and the direction of movement of the tool and contact is reversed. In this manner, the contact 67 is maintained on the outline during the progressive movement of the table 61 by rapid reversals of operation of the clutch mechanism. In a modification the control screen is movable and is associated directlv with the tool through the core of a solenoid which is controlled by a fixed contact engaging the movable screen.

In other examples, the following mixtures are specified : -a propylnaphthalenesulpho acid and a mixture of insoluble, alkylated pyridine homologues, dibutylnaphthalenesulpho acid and alkylated pyridines and quinolines, isopropyltetrahydronaphthalensulpho acid and tetrahydrorquinoline. Substituted derivatives of the aromatic sulpho acids may be used in the mixtures, such as the hydroxy, chlor, and amino bodies. Sulphonated naphthols, naphthylamines, and chlornapthalenes are specified. Di-iso-propylnaphthalenesulpho acid and monobutylnaphthalenesulpho acid are also mentioned.

Abstract: 869,256. Fluid-pressure servomotor control systems. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Aug. 8, 1958 [May 8, 1957], No. 14683/57. Class 135. A servomotor valve actuating mechanism, e.g. for a reversing valve for a free piston marine engine, comprises a servo-piston 15 for operating the valve, a servo-control valve 17, a pressuresensitive member 25 and a manual control member 27. The pressure-sensitive member 25 comprises a bellows sensitive to fluid pressure supplied through a pipe 26 and actuates a spring-loaded disc 23. Movement of the disc causes a lever 21 to rock about a fulcrum point 34, the other end of the lever transmitting motion to a link 21 which, through a pivot 31 moves rod 32 and hence the servo-valve 17. Feed-back from the servo-piston is provided through a floating lever 30. Manual control of the servo-valve 17 is provided by a hand wheel 29, rotation of which causes the rod 27 to move the pivot point 34 in a lateral direction. The rod 21 then pivots about the connection 33 and motion is transmitted to the link 20 and control valve 17. Instead of the bellows 25 and disc 23 a piston and cylinder may be substituted.
