Filed: 1924-10-11
Abstract: 242,750. Brown, W. H. Oct. 11, 1924. Special quantities, registering.-An electricity meter actuates one or other of two counting-trains according to the direction of rotation of the armature, means such as a switch operated by a clock, a current-operated relay, or a power-factor relay being provided for reversing the direction of rotation. The spindle 11 of the armature disc 12 carries a worm 10 engaging a worm-wheel 13, on the spindle 14: of which is mounted a cross-member 15 carrying a planet-wheel 16 which engages two sun-wheels 17, 18 freely journaled on the spindle 14. The wheel 17 drives, through spurgearing 9, 20, a ratchet-whsel 22. A second ratchet-wheel 26 is driven directly by the sunwheel 18. Pawls 23, 27 permit rotation of the wheels 22, 26 in a clockwise direction only, when viewed in the direction of the arrows 24. Clockwise rotation of the disc 12 is recorded on the counting-train connected to the shaft 21, that driven by the shaft 25 recording counterclockwise rotation. Reversal of direction may be effected by connecting the pressure winding to the mains through a reversing-switch. According to the Provisional Specification, a centre tapping on the pressure coil may be connected to one main, the other main being alternatively connected to either end of the coil by a two-way switch; also the crown-wheels of a differential gear may be driven directly by the meter shaft.

Title: A method of transmitting electrical signals along coaxial lines
IPC: H04B3/28
Filed: 1962-06-22
Abstract: 954,826. Preventing inductive disturbances. STANDARD TELEPHONES & CABLES Ltd. June 22, 1962 [June 27, 1961], No. 24172/62. Drawings to Specification. Heading H4R. In a coaxial cable, currents induced, by neighbouring power lines, into the inner conductor are reduced by connecting inductances between the outer conductor and the metallic sheath of the cable. The invention is of particular value where the inner conductor carries the D.C. power for transistorized unattended repeater stations which might otherwise be damaged by the induced currents. The inductances which should have low ohmic resistance may be situated at the main repeater stations which also supply the D.C., or may be distributed along the line, e.g. at every other unattended repeater station. Where a cable contains a plurality of coaxial pairs, whose outer conductors are in contact, the inductance may be common to them all.

Title: Improvements in Portable Air and Gas Compressors.
Inventor: CORPI DOMENICO
IPC: F04B25/00
Filed: 1919-10-09
Abstract: 133,701. Corpi, D., and Pretot, M. Sept. 3, 1918, [Convention date] Compound piston pumps; actuating pumps by fluid-pressure motors.-In a two-stage air or gas compressor wherein the first and second stages of compression take place in the crank case and cylinder respectively, the compressed fluid from the crank case is transferred to the cylinder through a passage leading to a valve-controlled inlet in the cylinder head the valve being closed by a spring and opening under an assigned pressure. As shown, air enters the crank case by a spring-controlled valve 7 and is compressed on the down stroke of the piston and delivered to a passage 9. At the end of the stroke a valve at the end of the passage introduces the air through the cylinder head. Air also enters the cylinder by a valve 11 in the head during the down stroke. On the up stroke, the air is further compressed in the cylinder and delivered through a valve 13 and the crank case is again filled through the valve 7. A compression group comprises two compressing and two driving cylinders working on the two-stroke cycle mounted on the same shaft on a single frame or chassis. Regulating devices may be provided; cooling is effected by air or water circulation. Any kind of motor may be used, and the valves may be operated mechanically. According to the Specification as open to inspection under Sect. 91 (3) (a), the passage 9 may terminate at a port in the cylinder wall which is shut off by the piston from the upper part of the cylinder during the main part of the stroke, but opened thereto when the piston is in its lowest position, as shown in Fig. 1 (Cancelled). This subject-matter does not appear in the Speeification as accepted.

Title: Improvements in or relating to fluid operated actuators
Inventor: GEYER HOWARD M
IPC: F15B15/26
Filed: 1970-05-22
Abstract: 1,272,870. Fluid operated actuators. PNEUMO DYNAMICS CORP. May 22, 1970 [July 17, 1969], No.24848/70. Heading F1P. A fluid operated actuator comprises a cylinder 2 slidable over a fixed piston 28 carried by a piston-rod 7, the rod 7 accommodating passages for the fluid supply to and return from the cylinder chambers 29, 49 on opposite sides of the piston and a synchronizing screw 34 rotatable by axial movement of the cylinder. The rod 7 is fixed in a stationary housing 8 provided with ports 18, 19 for actuating fluid. Fluid supplied to the port 19 flows through radial ports 23 in the rod 7 into an annular space 26 between the rod 7 and a porting tube 25, and thence through radial ports 27 to the cylinder chamber 29. Fluid supplied to the port 18 flows to the other cylinder chamber through the inside of the synchronizing screw 34 and ports 51 in the porting tube 25. In the retracted position a tube 46 inside the screw 34 engages a spring 67, thereby to move a dog clutch member 60 on the tube 46 into engagement with a dog clutch member 56 fixed in the housing 8. Thus the cylinder is locked and has to be released prior to extending the actuator by pressurizing a piston 70, 71 to separate the clutch members 56, 60. After an initial extension movement the spring 67 becomes ineffective and the piston 70, 71 is de-pressurized, a spring 76 then maintaining the clutch members disengaged. The screw 34 is provided with a gear-wheel 42 which drives a worm 43 which may be coupled to the worms of other actuators to ensure their synchronous operation.
