Title: Improvements in or relating to electricity supply meters
Inventor: GRAY BERNARD HERBERT LESLIE
IPC: G01R11/56
Filed: 1965-05-25
Abstract: 1,143,084. Electric supply meters. SANGAMO WESTON Ltd. May 17, 1966 [May 25, 1965], No.22180/65. Heading G1Q. [Also in Division G4] For metering electricity supply according to a tariff which is different at different times (e. g. by day and by night), a meter has two registers, one of which is driven directly from the meter rotor and the other at a rate governed by the meter rotor but powered by an independent drive source operating through a slipping clutch. The arrangement is such that either (a) one register indicates total supply and the other only the 'day' supply or (b) one indicates 'day' only and the other 'night' only. Fig. 1 depicts an example of type (a). The meter rotor (not shown) drives a worm 10, gear train 13 and thence register 14 at all times. During the higher tariff ('day') periods a constant speed motor 23 is energized to drive register 18 at a speed which, but for the slipping clutch 19-20, would exceed the full load registration speed. However, the pawl-and-ratchet 15-16 prevents register 18 running faster than register 14 so that both registers run together whenever motor 23 is running. When motor 23 is stopped, the pawl 16 slips over the ratchet wheel 15 and only register 14 is driven. The motor 23 is switched by a time switch 25 or by supply current impulses. A neon or like indicator 26 signals that motor 23 is running. In Fig. 1, changes in the registration rates are made by changing the gear trains 13 and 24. Fig. 2 (not shown) depicts an alternative arrangement in which these gear trains are of fixed transmission ratio and interchangeable gears (13a, 24a) are interposed between gear-wheel pairs 12, 37 and 17, 38 of Fig. 1. Fig. 3 (not shown) depicts an example of type (b), in which in addition to the pawl-and-ratchet 15-16 of Fig. 1 the two gear trains are also linked by a differential gear (29) consisting of two facing crown wheels (28, 32) with a planetary gear carrier (33) between them. The crown wheel (32) associated with the motor-driven register drives that register (18) but the other register (14a) is driven by the planetary gear carrier. Thus when the motor is running, and so both gear trains turning, the two crown wheels (28, 32) turn and the planet carrier does not so that only the 'day' register (18) is driven. When the motor is not running, the planet carrier rotates to drive only the 'night' register (14a). In this system, the two registers run in opposite directions, but this can be avoided if one of the crown wheels (28) and the planet carrier' exchange functions: i.e. if the meter rotor drives the carrier and the crown wheel drives the appropriate register.

Title: Improvements in methods of and apparatus for treating coal slurry
IPC: B01D21/00
Filed: 1930-07-23
Abstract: 354,986. Purifying water; gravityseparation apparatus. NORTON, B., Sandford Hall, Claverley, Shropshire. July 23, 1930, No. 22276. [Class 46.] Water which has been used for washing coal is delivered to a main settling tank 16, Fig. 4, from the upper part of which water for further washing is withdrawn through a pipe 17 while slurry water is withdrawn through a pipe 18 and delivered to one or more secondary settling tanks 3, from which it flows into a sump 6 and is returned by a pump 15 to the tank 16. Fine coal may be removed from the slurry water by a vibrating sieve 19 before it reaches the tanks 3. Figs. 1 and 2 show alternative secondary settling tanks 2, 3, to which the water is supplied alternately by a trough 1 and a solution of alum or other chemical agent to accelerate settling from a tank 14. A scraper conveyer 7 removes matter deposited as either tank is being filled. Any water overflowing passes over the inner side and is led by a trough 5 to the sump 6. When one tank is full the water is directed to the other tank and the scraper 7 of the full tank is brought to rest so as to allow of a quiescent settling period, at the end of which the water is drawn off from near the liquid level through a float-controlled hinged or flexible outlet pipe 12 leading to the sump 6. After removal of the water, the settled matter is removed by the scraper 7 and delivered by a conveyer 9 to a bunker 10.

Abstract: 1,080,061. Umbrella for unimpeded sheltering. RAINBEATER Ltd. May 26, 1966 [May 26, 1965], No. 22290/65. Heading A4P. An umbrella for unimpeded sheltering comprises a shank 10, a plurality of ribs 13 supporting a covering 15, hinged to a member, preferably a collar 12, displaceable along the shaft, a plurality of stretchers 14 each hinged to the corresponding rib and to a fixed ring 11 near one end of the shank so that when the umbrella is in the closed position the ribs, stretchers and covering lie along the shank (Fig. 4, not shown), and when the umbrella is open, the ribs and covering form a bowl with the shank projecting from the convex surface (Fig. 1). A spring-loaded catch 16 is preferably located on the shank (Fig. 3) in such a position relative to the fixed ring that the collar can be maintained to hold the ribs and cover in the open position. The shank is preferably provided with a hinge 19 to enable flexure of the shank, the hinge being positioned beyond the possible extreme travel of the collar (i.e. when the umbrela is closed); a sleeve 24 can be slid over the hinge when desired to prevent flexure. The projecting end of the shank may be hollow and enclose an extensible portion 25. Fig. 1 illustrates the umbrella in use on the ground as a shield from wind and driving rain; the umbrella may also be fitted on some overhead structure projecting downwards with the complete shank straight.

Title: Production of salt crystals from brine by evaporation
Inventor: PANAITESCU GRIGORE
IPC: B01D9/00
Filed: 1965-05-26
Abstract: 1,091,723. Production of salt crystals; evaporation of brine. MINISTERUL MINELOR SI ENERGIEI ELECTRICE RUMANIAN. May 26, 1965, No. 22203/65. Heading BIB. Salt crystals are produced from brine by introducing the brine and a warm gas into a mixing vessel 1 where a foam of brine in gas is formed; this foam passes into a separator 2 where the gas, saturated with water-vapour, is disengaged and is discharged from the top of the separator, while fine crystals of salt in brine settle downwards. The suspension flows through pipe 8 into classifier 9, where the brine and fine crystals flow upwards while a suspension of the heavier crystals flows down extractor 11 where it is washed with fresh brine entering through line 12. The suspension flows into thickener 13 which is also supplied with fresh brine through pipe 14. The thin suspension leaving the top of thickener 13 is pumped to vessel 1 together with the brine from the top of classifier 9. The thick suspension flows from the bottom of the thickener 13 into washing device 15, from which the product crystals are withdrawn. The mother liquor from device 15 is pumped to the thickener. The upper layer of foam in separator 2 contains insoluble impurities; this upper layer is evacuated from the separator by steam-ejector 5 and is conveyed to filter 6, from which the impurites are discharged. The filtrate is pumped back to separator 2.

Title: Electrodynamic Exciter
IPC: H02K33/18
Filed: 1966-05-19
Abstract: 1,151,192. Reciprocating motors. TEXTRON ELECTRONICS Inc. 19 May, 1966 [28 May, 1965], No. 22294/66. Heading H2A. An electrodynamic exciter comprises a stator with an annular gap, symmetrical low-reluctance flux paths around both ends of the gap, and openings providing communication between the gap and the exterior, a unidirectional field across the gap, an armature supported for movement in the openings and having a closed loop of not less than one turn of conductive material in the gap, and a stationary winding coupled to an A.C. source and inductively coupled to the loop, the armature comprising a supporting spider having plates joined along a vertical central axis and radiating therefrom, and a hollow cylindrical section constituting the closed loop, the cylindrical section being joined at one of its ends coaxially to an end of the supporting spider. In one embodiment, a cylindrical polepiece 30, Fig. 2, mounted vertically, is surrounded at its centre by a concentric annular polepiece 31 which is much shorter. Above and below the outer polepiece 31 are located windings 35, 36, to which D.C. is applied to produce a stationary magnetic field, and above and below these again are mounted end plates 33 whose outer -faces are coterminous with the ends of the central polepiece. In the air gap 34 between the polepieces is disposed a stationary winding in two parts, one part 46 closely adjacent to the inner surface of the outer polepiece and the other 45 closely adjacent to the outer surface of the inner polepiece; both parts have an axial extent equal to that of the outer polepiece. Each part consists of a plurality of hollow conductors each extending for, e.g., 2<SP>3</SP>/ 8  turns, the conductors of both parts all being connected in series to form a single winding. Cooling liquid is passed through the conductors and A.C. is fed to the whole winding. Between the parts of this winding is located the armature 39 forming the moving part of the shaker: it consists of a cylinder 44, Fig. 5, of conductive material (e.g. aluminium), providing a closed loop path for the induced current, and having welded to it, at the top, a " spider " consisting of four radial plates 47 to 50 welded to one another along the cylinder axis and 90 degrees apart. These plates are accommodated in vertical cuts forming a slot of cruciform section in the upper part of the central polepiece. The cylindrical part of the armature is provided with interconnected passages 60 to which cooling liquid is supplied. The spider part of the armature is mounted at the top by strap springs 40, Fig. 2, on the upper end plate of the apparatus, and is guided at the bottom by a piston 55 at the end of a short cylindrical extension 54 movable in a bushed cylindrical cavity 59 in the inner polepiece. In operation the armature oscillates vertically when D.C. is applied to the field winding and A.C. is applied to the driving winding.

Title: A device for restraining return motion
IPC: F16D41/08
Filed: 1948-08-24
Abstract: 652,546. Ratchet gearing; locking devices. VITKOVICKE ZELEZARNY NARODNI PODNIK, and KOUN, M. Aug. 24, 1948, No. 22303. Convention date, Aug. 26, 1947. [Class 80(iii)] A housing 1, Fig. 3, slidable along a guide 4 (which may be a rod, cable, chain or the like), is restrained from return motion by wedging means comprising two or more cheeks 2, 3 normally spring-pressed into engagement with the guide. Balls or rollers 5 are interposed between the parallel wedging surfaces of the cheeks 2, 3 and the housing 1. Initial movement in the direction S<SP>2</SP> compresses springs 8 until motion is unrestrained. Initial movement in direction S<SP>1</SP> causes the cheeks 2, 3 firmly to clamp the guide 4, thus preventing motion in this direction unless a lever 9 is rotated to compress the springs 8 and release the cheeks. Two oppositely acting wedging devices may be contained in one housing, Fig. 4, so that the direction of locking may be changeable. either the bolts 19 or the bolts 19a being withdrawn and held by pins 20. The device may be used as ratchet means in an apparatus in which it is desired to convert reciprocating motion into step-by-step motion along a guide. In one application a drilling hammer is rigid with a restraining device according to Fig. 3 and is automatically advanced along a fixed guide by virtue of the reaction on the casing of the impact piston. In a second application a coal cutting machine carries two restraining devices, the one rigid with the machine to prevent backrunning and the other reciprocated by a motor carried by the machine. The amplitude of the reciprocation is adjusted by moving the pivot pin of an oscillating slotted lever.

Title: Radio Transmitter for High Voltage Electric Power Transmission Line
IPC: H03L1/04
Filed: 1968-05-13
Abstract: 1,185,584. Radio transmitting systems. S. & C. ELECTRIC CO. 13 May, 1968 [17 Jan., 1968], No. 22676/68. Heading H4L. [Also in Divisions G3 and H2] A radio transmitter for mounting on, and for operation at the potential of, a high voltage power transmission line conductor 10, e.g. for use in the protective system of Specifications 1,121,720 and 1,121,719, comprises means 11, 12 responsive to the current in the conductor for energizing the transmitter, means 23 for controlling a carrier frequency, and means 37, 44 for maintaining the operating temperature of the means 23 within a predetermined temperature range to prevent unwanted shift in carrier frequency due to ambient temperature changes. Thus, the crystal oscillator and modulation circuit of the transmitter may be housed in an insulating housing 37 provided with a heater 44 which may be a self-regulating positive temperature coefficient resistor, Fig. 1 (not shown), or a resistor of substantially constant resistance controlled by a relay 45. This relay is controlled by a negative temperature coefficient resistor 55 which in response to a fall in temperature causes a unijunction transistor 54 to oscillate, its output being rectified by a diode 63 and causing a transistor 56 to conduct to energize the relay 45 which closes its contacts 48, 50. Energization of the heater 44 may be delayed until a predetermined current flows in the conductor 10 for an initial period, i.e. to prevent delay in the initial energization of the transmitter circuits. The delay circuit includes a capacitor 72 which is charged when sufficient voltage has existed across a Zener diode 71 for an interval determined by a resistor 70 and the capacitor. This causes a unijunction transistor 73 to oscillate to render a silicon controlled rectifier 76 conducting.

Title: Rotary printing machines
IPC: B41F9/14
Filed: 1939-08-04
Abstract: 534,654. Printing-machines. GRIFFIN, E. G. (American Bank Note Co.). Aug. 4, 1939, No. 22688. [Class 100 (ii)] A rotary gravure printing machine of the kind in which a D-impression roller 12 coacts with a printing cylinder 10 to which is secured an engraved plate 11 is constructed with improved methods of mounting and actuating the wipeing and polishing devices so as to operate without undue vibration and so that the machine can be driven at an increased speed. The machine is fitted with two wiping-pads 14a, 14b, over which wiping paper is led, and with a similar polishing pad 14c, which are arranged to act on the plate 11 when it is out of contact with the cylinder 12. The cylinder 12 is formed at the end to which the blanket is attached with a bent-in curved part of large radius so as to minimise vibration when the front end of the plate 11 first engages the cylinder 12. The pads 14a, 14b, are reciprocated by eccentrics 24, 25 on a shaft 20 driven by reduction gearing from a shaft 19, and the pad 14c, is reciprocated by an eccentric 29 on a shaft 27 driven by reduction gearing from a shaft 30. The pad 14c is arranged to operate at a higher frequency than the pads 14a, 14b. Each eccentric is clamped to its shaft in such a manner that it is angularly adjustable, and so the phase of the reciprocations can be varied. The shafts 20, 22 are fitted with counterweights 26, 32 which act like flywheels and prevent chattering of the wipers. The pads are made with bars of a material such as an alloy of aluminium which is light but possesses high compressive strength. The bars 14, Fig. 5 are covered with felt 18, and are formed with ends 16 of polygonal crosssection adapted to slide in bearing openings 36 in the frame fitted with anti-friction metal bearing plates 38, 39 connected by posts 37. The bearing plates are adjustable by means of micrometer screws 43 with bearing heads 42 which engage in T-slots 41 in extensions 40 secured to the lower bearing plate, and so the pads are adjustable radially of the cylinder 10. A spring lock 51 engages notches in a sleeve 48 to indicate the extent of adjustment of the pad.

Abstract: 475,599. Connecting and disconnecting arrangements for friction gearing. GENERAL MOTORS CORPORATION. Aug. 18, 1936, No. 22777. Convention date, Jan. 9. [Class 80 (i)] [Also in Group XXVII] An engine starter comprises a pair of driving discs 33, 34 adapted to be engaged, independently of the operation of the starting motor, with the opposite faces of a driven disc 35 connected to the engine to be started. The driving discs 33, 34 are interconnected by camming provisions so that relative rotation of the discs in response to operation of the motor results in their being pressed against the driven disc with a pressure sufficient for driving engagement, the camming provisions being formed on the juxtaposed outside and inside cylindrical surfaces-of nested members 30, 34a on which the driving discs are carried. As the disc 33 is formed on a sleeve 30 splined at 31 on the armature shaft 26 of the starting motor 20, and the disc 34 is the end face of a sleeve 34a connected to the sleeve 30 by balls 38 occupying mating helical grooves 39 40 in the sleeves. External helical splines 41 on the sleeve 34a are engaged by the flange 42 of a sleeve 43 having slots 48 engaged by tongues on a disc 44 riveted on the end of the sleeve 30 A spring 45 is interposed between the disc 44 and the flange 42, and a spring 32 between the armature 27 and the end of the sleeve 30. A flange 49 on the sleeve 43 is engaged by the bifurcated end of a lever 70 connected by a link 84 to the armature 82 of an electromagnet 75 similar to that described in Specification 473,315. The upper end of the lever 70 has a notch 71 urged by a spring 76 into engagement with a pin 72 on a bracket 73 on the electromagnet frame. On closing a switch 105 con. necting a battery 101 to the ignition circuit 103 and to the electromagnet at 104, the resulting movement of the lever 70 moves the sleeves 42 &c. bodily to the left to bring the disc 33 intc engagement with the disc 35. Further move. ment of the lever 70 and sleeve 43 causes the sleeve 34a and disc 34 to be moved to the right by means of the helical connection 38 ... 4C between the sleeves 34a, 30, rotation of the interconnected sleeves 30, 43 being prevented bv the inertia due to the mass of the armature shaft 26 and parts rotatable therewith. When the disc 34 comes into contact with the disc 35, further movement of the lever 70 causes a contact 95 on an extension 85 of the armature 82 to close the circuit of the starting motor 20. The discs 33, 34 are then tightened by the helical connection 38-40 to transmit the drive. When the engine starts, this engagement is released.
