Title: Improvements in and relating to charging electric storage batteries
Inventor: BURKETT WILFORD BENSON
IPC: H02J7/00
Filed: 1968-01-25
Abstract: 1,219,324. Batteries &c., electric. McCULLOCH CORP. 25 Jan., 1968 [31 Jan., 1967], No. 3857/68. Heading H1B. [Also in Division H2] A method of rapidly charging an electric battery-such as a sealed nickel-cadmium battery-comprises the steps of charging the battery at a high rate until the battery condition reaches a predetermined value, disconnecting the battery from the charging supply and connecting it to a load and then discharging the battery through the load at a high rate for a short time. The battery condition may be the terminal voltage of the battery during charging, the internal pressure or the temperature of the battery, these three conditions being interrelated and, if desired, these conditions may be made dependent upon ambient temperature. The charging process may be terminated by means responsive to the battery terminal voltage, the average current flow during discharging at the energy values during charging and discharging. A battery 11 is charged from a source 10 of direct current by way of a switch 12, current regulator 13 and a battery condition dependent switch 14. A sensor 15, compensated for ambient temperature by a sensor 16, senses the voltage of the battery during charging and, when a predetermined terminal voltage is reached, operates switch 14 to remove the battery 11 from the charging source 10 and connects the battery to a load 18 by way of a switch 17 whereupon the battery discharges through the load. At a given battery voltage during discharge the sensor 15 causes switches 14, 17 to revert to normal and the charging cycle is repeated. Alternatively the sensor 15 may sense the other battery conditions mentioned above. The charging operation may be ended by operation of the switch 12 either by a time mechanism 19, a load current sensor 20 or a load voltage sensor 21 compensated for ambient temperature by a sensor 22. The control circuit of the elements 14, 15, 17 includes Zener diodes, a thyristor and electromagnetically-operated relays together with an RC timing network.

Abstract: 1,179,910. Fluid blast switches; electromagnetically assisted switches. WESTINGHOUSE ELECTRIC CORP. 25 Jan., 1968 [16 Feb., 1967], No. 3994/68. Heading H1N. In a fluid blast switch of the " puffer" type the movement of piston 8 is assisted electromagnetically by a coil 33 in series with the arc 15 during interruption and co-operating with a fixed shorted coil 37. The piston 8 which moves in a fixed insulating cylinder 56 carries the movable contact 6 of the switch, an arcing electrode 31 insulated from contact 6 and an insulating nozzle 39. The coil 33 is connected between the electrode 31 and contact 6. During opening piston 8 is initially moved by a rod 17; the flow of fluid through openings 38 in piston 8 rapidly transfers the arc struck between separating contacts 5, 6 to the electrode 31 connecting the coil 33 in series. The coil 33 induces a current in the shorted turn 37 and is thus repelled by it, downwards, to assist the opening operation. A second fixed coil 52 may be arranged adjacent the shorted coil 37 and the current in coil 52 is arranged to flow also in a third coil 53; this in turn induces a current in disc 50 forming a floating piston which is thus repelled upwards to increase the flow of fluid. The assembly may be mounted in a tank filled with SF 6  at 60 p.s.i. In a modification (Figs. 8, 9, not shown), the cylinder is conducting and the upper part of its wall forms the shorted coil.

Title: Improvements in jacks for automobiles
IPC: B66F3/42
Filed: 1927-02-14
Abstract: 276,237. Dehn, F. B., (Aladdin Hydraulic Jack Co.). Feb. 14, 1927. Single-acting suction-valveless bucket pumps; buckets; suction reservoirs. -A hydraulic jack comprises a crank operated pump of the bucket type, an open-ended lifting cylinder and a surrounding casing serving as a reservoir for the operating fluid. The crutch 26 has a notched pillar 21 and is non-rotatably mounted in the hollow lifting plunger 12 by means of a pin and groove connection 22 and is adjustable therein by means of a spring catch 20 and notches 25. The plunger 12 is mounted in the lifting cylinder 3, open at its upper end and provided near the top with release apertures A to prevent an overlift. The lifting cylinder is connected to the pump cylinder 6 by means of a channel 7 and check valve 30. The pump operating shaft 39 is rocked by a handle comprising a socket 41, a duplex extension 42 pivoted to a further extension 44, the joint being fitted with a slider 48 for ensuring rigidity when required, and a handle 46. The shaft 39 carries a crank 38 on which the pump rod 32 is mounted. The pump piston comprises a flange 34, Fig. 3, on the pump rod, a cruciform extension 33, an annular washer B secured to the cruciform extension by a split pin and a leather ring 35 surrounding the cruciform extension and slidable thereon between the limits set by the flange and washer so as to leave a passage way at either end as required. A casing 8 bolted to the base plate 1 surrounds both cylinders and contains the operating fluid. In operation, downward movement of the pump piston forces pressure fluid past the check valve into the lifting cylinder and raises the load. When the pump piston moves upward, the check valve closes, the ring 35 moves to its lower position and fluid passes from above the pump piston to beneath it, ready for the next pressure stroke. To lower the load, the handle is rocked beyond the normal range, so depressing the pump piston until its lower end strikes and opens the check valve and the ring 35 is below the upper ends of slots 28, Fig. 5, in a liner 27 in the pump cylinder, so permitting the pressure fluid to escape from the lifting cylinder past the check valve and pump piston into the upper part of the pump cylinder.

Title: Lever locks
IPC: E05B25/00
Filed: 1962-02-03
Abstract: 949,350. Key locks. JOSIAH PARKES & SONS Ltd., and E. F. ORDIDGE. Dec. 21, 1962 [Feb. 3, 1962], No. 4233/62. Heading E2A. The invention relates to lever locks of the kind in which a key operable thrower 10 actuates a dead bolt 12 either directly or through an intermediate sliding runner and in which before the bolt can be thrown security levers 21 of either the pivoted or the sliding type and having gatings 22 interconnecting end pockets 23 for detaining engagement with a stump 24 fixed on the bolt or runner required to be correctly lifted by respective lever steps on the key bit so as to free its stump from the detaining engagement of the pockets at one end of the lever gatings and to register all the lever gatings so that the stump can pass therethrough into the pockets at the opposite end of said gatings as the key and thrower are turned further, the throwing movement throughout maintaining the correct lift of the levers and thereafter by continued turning of the key in the same direction into its starting position with its bit in register with the keyhole allowing the levers, which are spring loaded towards the key, to fall so that the pockets at said opposite end of their gatings move into detaining engagement with the said stump. According to the invention the overall length of the end pockets and interconnecting gating is the same in all the security levers but one or some of said levers has or have somewhat longer end pockets and consequently a somewhat shorter gating than the other or others so that in the event of said other lever or levers being held up completely by the stump as a result of a slight underthrow of the bolt or runner said lever or levers with the shorter gating will fall into a stump obstructing position to afford a measure of security. In the construction shown a runner 13 is used and the levers are of the sliding type. A single one of the security levers has the shorter gating and this is produced by providing rebates 29; thus if there is a slight underthrow of the runner 13 the lever will fall to the extent permitted by the height of the rebates 29 while the other lever or levers will remain held up by the runner stump 24. The thrower is provided with a radial projection 30 which is diametrically opposite its runner throwing arm and the runner 13 is provided with a pair of oppositely presented abutment faces 31 one or other of which will, in the event of a slight underthrow of the runner 13 in either direction by the throwing arm of the thrower 10, be left in the path of rotation of the projection 30 and will be engaged by it during continued rotation of the thrower in the same direction towards the keyhole registering position so as to complete the throw of the runner 13 to the full extent. The key cannot be turned more than a full turn because the runner 13 will engage one or other of the casing walls when it is fully thrown.

Title: Improvements in or relating to adapters for the remote control of electric lamps and the like
IPC: H01R33/94
Filed: 1939-02-09
Abstract: 524,848. Lamp-holders. VORONIN, P. S. Feb. 9, 1939, No. 4234. Convention date, Feb. 10, 1938. [Class 38 (i)] An adapter for enabling a lamp or the like to be controlled by a remote switch consists of a unitary plug and socket 1, one end of which has a pair of contacts 6, 7 for connection to a current supply while the other end has contacts 10 for connection to a current consuming device (e.g., a lamp 4), one of the supply contacts 7 being directly connected to one of the consuming contacts 10, and other contacts at each end being connected by a flexible multiple conductor having three or more conductors 13 to a remote switch or switches 12 controlling parallel circuits including said contacts. This arrangement enables a resistance 14, Fig. 1, to be included in circuit with the switch, to provide for using the lamp either at full brilliance, or dimmed. The resistance 14 may be housed within the member 1. and further resistances 15 may be inserted in one or other of the leads 13. In the arrangement shown in Fig. 2, a doublefilament lamp is used in conjunction with a multiple switch or separate switches 12, 12<1>, the member 1 having three inner contacts 10, one of which is directly connected to one of the outer contacts. With 'this arrangement, a single filament, or both filaments either in series or parallel, may be used. The Specification, as open to inspection under Sect. 91, describes also the provision of an on-and-off switch directlv connected to terminals of the combined plug and socket by two leads. It also describes the indirect connection of the plug and socket to a remote switch through a distribution board. Mention is also made of the application of the arrangement shown in Fig. 2 to an electric stove having two separate heating-elements. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in wave-distorting systems for electric signalling
IPC: H03G11/00
Filed: 1926-02-15
Abstract: 270,817. Standard Telephones & Cables, Ltd., (Western Electric Co.. Inc.). Feb. 15, 1926. Frequency, changing. - A wave-distorting device for imposing voltage limitations in electric signalling systems, and for generating harmonic frequencies, comprises an input circuit coupled through a plurality of branches to an output circuit, the transmission characteristics of the branches being dissimilar but so related that the resultant transmission characteristic has a reverse slope for voltages beyond a given value. As shown in Fig. 1, the input circuit 1 and the output circuit 4 are connected as diagonals of a bridge, of which the arms comprise three resistances a, b, c and a duplex rectifier 2. The rectifier 2 comprises a pair of reversely-connected diodes 2 with their plates negatively polarized by batteries 3. The output voltages E4 is then the difference between the voltages Eb across resistance b and Ec across resistance c. If the current taken by the output circuit is small, then Eb is proportional to Ec the input voltage and can be represented by the straight line Eb in Fig. 2, in which the voltages across the various elements are plotted as ordinates, and the input voltages as abscissae. The voltage Ec across the resistance c will be zero until the applied voltage Ec is greater than that of the batteries 3, and causes current to flow through this branch. The voltage Ec can therefore be represented in Fig. 2 in the form Ec, y, z Ec, and the resultant voltage E4 or (Eb- Ec) in the form E4, W, X, E4. Thus if a wave of peak voltage greater than E3 is applied, the output voltage is limited, the wave-form is distorted, and harmonics are produced in the output circuit. By suitable selection of the input voltage Eo, and the critical voltage E3, the third harmonic may be made predominant and may be selected by suitable means. When the output circuit 4 is taken to a valve amplifier of the kind in which one half-cycle is inoperative, one of the rectifiers 2 may be omitted. A condenser is connected in series with the impedance c, and a battery connected across this condenser to provide grid bias for the amplifier, and to replace the battery 3. The impedance c comprises a resistance shunted bv a high-frequency choke coil. In a further modification, Fig. 4, the input in line 1 is first amplified by an ordinary valve amplifier 21, and is then taken through two branches one of which includes the valve 22, the other branch comprising a resistance 28 and a large blocking-condenser 29. Owing to the 180 degrees phase displacement that occurs in the valve, the two branches produce opposite effects in the plate circuit. A resistance 26 in the platscircuit assists in securing the desired phase relation. The amplifier 21 may be arranged to be saturated by an excessive input voltage.

Abstract: 1,214,688. Feeding record tapes. NEWELL INDUSTRIES Inc. 20 June, 1968 [26 June, 1967], No. 4336/70. Divided out of 1,214,687. Heading G5R. A tape carries two recorded tracks arranged for playback respectively in two opposite directions of tape movement and a control signal comprising two portions of substantially the same frequency but 180 degrees out of phase with each other recorded respectively on two tracks arranged to be played back simultaneously. As described, in a system as disclosed in Specification 1,214,687, the control signal is a low-level 25 Hz. tone in the two tracks of a stereophonic recording. The two portions tend to cancel each other in normal playback, but the signal is derived for control purposes, e.g. tape reversal, by adding the signal from one track to the inversion of the signal from the other track and passing the resultant signal through a 25 Hz. bandpass filter.
