Title: Improvements in or relating to electric watthour meters
Inventor: GRAY BERNARD HERBERT LESLIE
IPC: G06M1/38
Filed: 1965-05-25
Abstract: 1,142,856. Multiple tariff meters. SANGAMO WESTON Ltd. May 17, 1966 [May 25, 1965], No.22181/65. Heading G1Q. [Also in Division G4] A watt-hour meter with provision for total and excess-rate registration has the input drive 10 assisted by a synchronous electric motor 14. In one embodiment, Fig. 1, the motor drives a crown-wheel 37 of a first differential 36 directly and a crown-wheel 13 of a second differential 12 through a variable gear-drive 32, 26. The meter input 10 drives the opposite crown-wheels 38, 11. Crown-wheel 11 drives the total energy meter 16. An artificial load 41 on the planetary carrier 39 of the first differential enables the motor 14 to provide extra torque to the input without affecting its speed. If the speed of crown-wheel 11 exceeds in value the oppositely directed speed of crownwheel 13 the carrier 18 of the second differential drives the excess meter 24 through gear 23. The ratio of gear-drive 32, 26 is adjustable from outside the meter-case according to the rate at which excess metering is to apply. In a modification, Fig. 5, the motor 14 drives crown-wheel 70 through an epicyclic reduction gear 58 and a variable gear-drive 66, 87, 29, 26. If the speed of the motor input 10 is below excess then drive to meter 16 is effected through gears 76a, 64a and 85, the planetary gear 67 rotating in reverse but not affecting the excess meter 24 because of a pawl 71. If the speed is above excess planetary gear 67 drives forwardly through pawl 68. The input drive is assisted by motor 14 through a spring-pressed friction clutch 65. Motor failure. In Fig. 1 if motor 14 fails then both meters advance but the excess meter reads high. In Fig. 5 the total meter operates but clutch 65 slips and no excess registration is made. The motor 14 may be time-controlled to register excess during predetermined periods only.

Abstract: 772,325. Thermo-aluminic and like chemical reaction processes. WESTER, H., and WESTER, T., [trading as WESTERWERKE FABRIKEN HOCHFEUERFESTER ERZEUGNISSE]. Aug. 3, 1955 [Aug. 13, 1954], No. 22342/55. Class 83 (4). A method of producing metallo-ceramic agglomerates, including such as contain no free metal, by causing a pulverulent mixture capable of a controlled exothermal reaction and composed of one or more metals with one or more elements or compounds, to react and agglomerate by initial ignition in an impressed state in a mould and, after ignition, pressing the reacting material into the desired shape, is characterized in that the pressed agglomerates are removed from the moulds immediately they have been formed and are then transferred to a kiln wherein their temperature is first raised to the temperature at which the moulding took place, i.e. 1500‹ C., after which they are allowed to cool slowly to a temperature of 150‹ to 200‹ C. The pressed shapes are either placed on to the conveyer of a continuous kiln which has a temperature at the charging end equal to the moulding temperature but gradually decreasing along the length of the kiln or placed on to a road in the interior of a continuous kiln. In the latter instance the pressed shapes are successively displaced by the length of one shape towards the cooler end of the kiln as each new shape is pushed into the kiln. Specification 733,390 is referred to.

Abstract: 953,052. Latches. WILMOT-BREEDEN Ltd. July 1, 1960 [July 3, 1959; Jan. 5, 1960], Nos. 22884/59 and 317/60. Heading E2A. A door fastening of the link latch type comprises a spring loaded toggle linkage which is extended when the latch piece is in a latched position, release means for collapsing the toggle linkage to release the fastening, and a further toggle linkage which is extended when the latch piece is in the unlatched position and must be collapsed before latching can take place, the two toggle linkages utilizing a common link. A fastening, Fig. 1, comprises a latch piece 6 pivoted at 24 to a back plate 2, a generally triangular shaped lever 13 pivoted at 14, and a link 19, the lever 13 and link 19 forming a toggle linkage which is collapsed from the position shown to allow latching to take place. In addition, a cover plate 25 and a link 15 operatively connecting the lever 13 to the latch piece 6 are provided. Collapse of the linkage is caused by a keeper 1 which, when it contacts a face 29 of a lever 28 pivoted at 24 rotates the lever 28 to push the pivot point 18 over centre. In the latched position Fig. 5, a second toggle linkage formed by the lever 13 and a link 22 prevents rotation of the latch piece to an unlatched position until the linkage is collapsed by means of a handle actuated rod 27 which is shifted against a spring loading. A central handle operates two door fastenings simultaneously, the handle when turned clockwise, rotating a cam 43, Fig. 7, to shift operating links 35 and 37, the links having pins 52 situated in slots 44 in the cam. The links 35 and 37 are thus moved inwardly against springs 53. A lever type handle may be used in which cam portions integral with the handle bear against levers to shift the operating links.

Abstract: 1533671 Buffer store SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 3 June 1976 [5 June 1975] 23058/76 Heading G4A A buffer store includes an input serial-toparallel converter S/P controlled by input timing signals CKi, two n-bit registers M1, M2 connected alternately to the converter by respective write signals w1, w2 derived from the input timing signals, an output parallel to serial converter P/S to provide a serial output u controlled by output timing signals CKu and connected alternately to the two registers by read signals rl, r2 derived from the output timing signals and normally out of phase with the corresponding write signals w1, w2, and a control circuit C arranged when corresponding read and write signals rl, w1; r2, w2 overlap due to relative slippage between the input and output timing signals to exchange the two write or the two read signals thereby to repeat or delete one of the n-bit groups in registers M1, M2 from the output bit stream u. As shown one of the read signals, in this case r1, is compared with signals M<SP>+</SP>, M- which occur immediately before and immediately after respectively the corresponding write signal wl to detect when corresponding read and write signals have moved nearly into phase because of slippage between the input and output timing signals CKi, CKu. A positive comparison is gated by a signal #oi, which may indicate that the current data is the first slot in a PCM transmission containing only timing data used at a receiver, to generate a signal s which exchanges the two write signals. Thus depending on whether the positive comparison occurred with M<SP>+</SP> or M- one of the two n-bit groups in registers M1, M2 is deleted from or repeated in the bit stream i, the signal #oi, ensuring that any repetition or deletion occurs at a fixed point in the transmission cycle.

A frame b holding the screen bl is oscillated by a cam c<SP>1</SP> engaging rollers on extensions b<SP>2</SP> of the frame and the squeegee h is reciprocated along slide rods b<SP>3</SP> on the frame by lazy tongs f operating about a pivot f<SP>1</SP> by a cam d driven from the same source as cam c<SP>1</SP>. The cam d is operatively connected to a frame e which is thereby reciprocated on rods a<SP>2</SP> to cause the opening and closing of the lazy tongs slidably connected to the frame e. The forepart f of the lazy tongs is connected to the squeegee assembly by a rod g<SP>1</SP> carried by two runner members g2 carrying rollers g<SP>3</SP> running along rods b<SP>3</SP>. The squeegee is vertically adjustable in holders m which are pivoted in the side member g2 between limiting stop g<SP>5</SP> and the lifting of the squeegee over the the paint at the end of each stroke is effected by a roller h<SP>1</SP> engaging cams j, whereby a block h<SP>2</SP> provided on the roller is raised in a vertical slot g<SP>4</SP> in the member g2. The effective operation of the squeegee is controlled by vertically sliding bars i on the inside of the frame b which, for the squeegee to be active, are arranged in their raised position so that the roller h<SP>1</SP> can pass therebeneath, and for the squeegee to be out of action the bars i are lowered so that the rollers h<SP>1</SP> ride up the end slopes of the bars to travel on the top surface thereof and hold the squeegee above the screen. The operation of each slide bar i is controlled by pins l connected to the bars i by straps i<SP>1</SP>, acting in conjunction with a slide k<SP>2</SP>. Slides k<SP>2</SP> are moved by cams k<SP>3</SP> from a shaft and lever k, k<SP>1</SP> so that holes k<SP>4</SP> in the slides k<SP>2</SP> are either in register with apertures a<SP>4</SP> in the supporting frame a, in which case no movement is imparted to the pins l and bars i therefore remain in their lowered position, or holes k' are out of register with the apertures a<SP>4</SP>, causing the pins l to engage the slides k<SP>2</SP> and thus raise the bars i.

Abstract: 596,301. Weighing-apparatus. GUTHRIE. G. L. Nov. 24, 1944, No. 23458. [Class 143] [Also in Group XIX] A load measuring device 4 is mounted between the carrier bar 3 and the "polish rod clamp 5 of a pumping well and comprises a reaction block or cylinder 13 which is compressively deformed within the elastic limit of the material, when subjected to the load on the "polish rod 1." The reaction cylinder 13 is contained within an annular housing 10 and is separated therefrom by a chamber 16 containing liquid such that the lateral and vertical strains produced in the cylinder 13, by the load, cause a change in the capacity of the chamber 16, while a conduit 26 conveys the liquid expelled from the chamber 16 to a cylinder 25 where a piston is moved in proportion to the liquid displaced to operate a rack and an index member 24. An outwardly extending support 18 carries a recording device which comprises vertical guides 19, 20 fitted with sleeves 22, 23 to provide vertical movement to a semi-circular card holder 21 to which the sleeves are attached, thus allowing the index member 24 to mark the card according to load conditions. The card holder 21 is provided with a threaded lug or nut 44 and vertical movement thereof is effected by the rotation of a threaded screw 32 in the nut 44, the screw 32 being journalled in the support arm 18 and in a bracket 33, and provided with a pulley 34 at its lower end such that a cord 38, attached to a spring tensioned roller 35, passes round the pulley and over a free roller 36, being finally secured at a point near the stuffing box, thus as the carrier bar 3 and the load device 4 move up and down a rotary movement is imparted to the screw 32 which causes a vertical displacement of the card holder. A temperature compensator is included in the liquid line and comprises a chamber 28 fitted with an adjustable piston 29 mounted on a threaded shaft 30 and operated by a knob 31 so that the volume of liquid stored in the chamber 28 may be altered according to the expansion in the system due to temperature variation.
