Abstract: 300,317. British Power Railway Signal Co., Ltd., Glenn, S. L., and Pierce, E. E. Aug. 18,1927. Hand-levers. - An economy switch in the locking circuit of a hand-lever is separate from the lever frame, is located in any desired position and is operated by the movement of the catch-handle of the lever. A cable 9 is stretched above the quadrant 7 by a spring 10, passes over a pulley 5 on the catch-block 4 and under a pulley 6 on the quadrant and is connected to an economy switch 11, 12. Raising the catch-block flexes the cable and moves the switch arm. In modifications, the cable is flexed by the downward movement of the catch-block, the cable is replaced by a light shaft having levers placed to contact with the catch-block, and a Bowden wire is used to convey motion from the catch-block to the switch. When a lever has more than two fixed positions, the device is arranged to operate at each position. The movement transmitted may be arranged to be greater for one position of the hand-lever than for another and the switch be provided with suitable contacts to discriminate between the positions. A form of switch is shown in Fig. 7. The operating cable is secured to an eye-bolt 40 adjustably secured upon a lever 42 having a loose pivotal connection 44 with a sliding bar 25 carrying a springy contact bridge 28 backed by a spring leaf 29. The contact bridge engages cylindrical contact blocks 33 and is flexed in making contact so as to ensure a wiping action. The blocks 33 are secured upon insulator strips 32. The cable is tensioned by a spring 10 acting on a short arm 45 of the lever 42 with a force determined by the adjustment of a screw 46 Back contacts may be fitted at 32a.

Abstract: 500,124. Liquid-meters ; valves. MECHANICAL & GENERAL INVENTIONS CO., Ltd. (M.A.G.I.C., Ltd. (France), Soc. Anon.) Aug. 7, 1937, No. 21786. [Classes 69 (i) and 135] In a liquid-meter of the type in which a measuring-chamber 8 discharges through a siphon 21 into a delivery chamber 9, the siphon delivering into a pivotally-mounted perforated trough or cup 29 controlling the inflow valve 13 of the measuring- chamber, the cup 29 closes the valve 13 positively when the liquid is delivered to it. In the meter shown, the stem 12 of the valve 13 rests on an arm 31 projecting from the pivoted cup 29, the weight of the valve stem &c. overbalancing that of the cup when it is empty so that the valve remains open until the chamber 8 is filled, when the siphon commences to act and fills the cup, causing the latter to sink and close the valve positively. The valve is also closed when the chamber 9 is full by means of a pivoted float 32, which rises and causes a projection 321 on the float arm to raise the arm 31. The pear-shaped oppositely-directed chambers 8, 9 are formed in a cast body 7 and closed at the front by a cover-plate 10. The siphon 21 is formed by a groove in one of the end walls of the casting covered by a plate 24. A pivoted float 25 operates mechanically or electromagnetically at each filling of the measuring-chamber an indicator or totalizer 19, or both, housed in a chamber formed in the casting 7.

Abstract: 1365218 Semi-conductor memory elements COMMISSARIAT A L'ENERGIE ATOMIQUE 10 May 1972 [12 May 1971] 21808/72 Heading H1K A memory element for a random-access dynamic memory comprises two electrodes 8, 10 capacitively coupled to a semi-conductor substrate 2, and a further electrode, e.g. constituted by a surface-barrier contact or a diffused or ionimplanted region 4 of opposite conductivity type to the substrate 2, aligned with the capacitive electrodes 8, 10. The electrode 8 furthest from the region 4 serves as a storage electrode, having applied thereto a fixed potential V 2 . Fig. 2a shows how charge injected from the region 4 is transferred to the depletion region beneath the storage electrode 8 by the application of appropriate potentials to the region 4 and the control electrode 10, which may be physically smaller than the storage electrode 8. Fig. 2b shows the element in its storage mode. Due to spontaneous minority-carrier generation and subsequent recombination of the stored charge the store is dynamic, requiring to be replenished at regular intervals. Read-out and erasure is illustrated in Fig. 2c, being effected by the application of the same potential V 3  to both electrode 10 and region 4, where |V 3 |  > | V 2  | . For use in an array in which elements are accessed by simultaneous potentials applied along lines extending in two mutually orthogonal directions each element may be provided with two control electrodes such as 10, all three capacitive electrodes and the injecting region 4 being mutually aligned. In a memory device elements of the type described are arranged in an orthogonal array, all elements in a word line sharing a common strip-like injecting region 4. For a Si substrate the insulation of the capacitive electrodes 8, 10 may be silicon oxide or nitride, the electrodes themselves being Al or heavily doped Si.

Abstract: 650,011. A.C. commutator machines. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 18, 1948, No. 21826. Convention date, Aug. 23, 1947. [Class 35] An A.C. commutator machine, which may be used as a variable speed motor or a variable frequency generator or frequency changer, has a pair of stator windings having different pole-numbers, one of which is adjustably energized, and an armature wound so as to be inductive to each of these pole numbers. In its simplest form, Fig. 1, a variable speed motor has on its stator, a two-pole power winding 10, a four-pole control winding 9 whose excitation is regulated by a resistor, which in a modification is reversible to permit addition or subtraction of field strength, and a four-pole compensating winding 8 fed from the commutator of the machine. In operation the twopole excitation from winding 10 energizes the rotor and so feeds the four-pole compensating winding 8 which balances the four-pole ampereturns produced in the rotor. Excitation of the control winding 9 produces a four-pole field which, due to the rotation of the machine, generates a circulating current in the armature and compensating winding to produce an additional two-pole field, the four-pole fields of these units balancing out. This two-pole field can be made to buck or boost the field from field winding 10 and so the speed of the motor is regulated. If the machine is driven and the control resistors are replaced by a source of adjustable frequency a load of controlled frequency may be drawn from winding 10. A generator is shown in Fig. 4 in which the control winding 9 is initially excited from the mains and then the switch 20 may be opened to allow self excitation. The power generating winding 10 carries current from an additional set of brushes 24, 25, 26, set between the main brushes. A modified motor is described in which the power winding is wound for four and eight poles, the control with eight poles, and the rotor, which has six brushes, as shown in Fig. 4, shorted together, wound with four and eight poles. The machines may be single or poly-phase. Specification 16170/09, [Class 35], is referred to.
