Title: Electric motor and model vehicles including same
IPC: A63H29/22
Filed: 1974-04-23
Abstract: 1472280 Mechanical switches MABUCHI MOTOR KK 23 April 1974 17773/74 Heading H1N [Also in Division A6] An electric switch 4, Fig. 1, is arranged to be closed by the reaction torque of a battery driven electric motor 1 mounted on a pivotal support 1b whereby when the torque drops below a predetermined value the power circuit is cut off to protect the batteries. The switch is particularly intended for use in protecting rapidly rechargeable Ni-Cd batteries used in model planes, ships and automobiles. The switch body 4 of insulating material is mounted on a motor support bracket 2 and has an actuator 5 engaged by a projection 3 on the motor housing. A spring 8 Fig. 3, urges the contact 5a on the end of the actuator 5 away from the fixed contact 6a on an adjustable threaded support rod 6 mounted in a conductive end cap 4a. In operation the torque of the motor 1 maintains the contacts 5a, 5b in engagement until the power falls off thereby preventing the possibility of one cell being reverse charged. Examples are shown of the toy motor applied in a model aeroplane Fig. 5 (not shown) and a model ship Fig. 7 (not shown).

Title: Improvements in electric rheostats
IPC: H01C10/16
Filed: 1925-07-13
Abstract: 257,064. Crompton & Co., Ltd., and Jones,. W. F. July 13, 1925. Controllers, interlocking.- In rheostats for use in connection with motor starters in which the resistance elements are rotated to vary the resistance the elements are cooled by a medium, preferably oil or water, which is agitated by propellers rotated on moving the resistance elements. In the arrangements shown the resistance elements are wound on insulating cylinders along which contact rings are moved as described in Specifi. cation 242,807, [Class 38 (ii), Electric currents, Converting but devices such as that described in Specification 19604/00, [Class 37, Electricity. Measuring &c.], may also be employed. In the arrangement shown in Fig. 1, the cylinders L carrying the resistance elements are arranged around a spindle Z from which they are rotated by gears T, U and which carries propellers DD. The starting switch EE may be closed by a rod actuated by the contact rings when these are at the top of the cylinders L so that it can only be closed when the whole resistance is in circuit, being thereafter held .m electromagnetically. In the arrangement shown in Fig. 8 three cylinders L are carried by a single spindle Z which also carries the propellers DD. Fixed rings A connect metal bands HH on the cylinders connected to the ends of resistance wires to conductors JJ while the moving contact rings A<1> slide on a conduct rod LL. A nut NN on the spindle Z actuates interlocking gear through a rod SS or may operate an interlocking switch directly. If water is used as the cooling medium it may be covered with a layer of oil. Specification 235,311 also is referred to.

Title: Fluid pressure servomotor control systems
IPC: F15B17/00
Filed: 1958-06-04
Abstract: 844,223. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. June 4, 1958 [June 7, 1957], No. 17883/58. Addition to 829,030. Class 103 (1). [Also in Group XXIX] The mechanism of the parent case is modified by providing the single beat valve 42 with a stem 70 embodying a reduced diameter part 90 that is received in a tube 68 attached to the control lever 62, the whole being accommodated with the hollow rod 54 of the servo-piston B, a vacuum seal 72 being disposed between the tube 68 and the rod. The stem 70 and tube 68 are connected by a detent comprising a sheet-metal stamping D having an annular part 80 and fingers 86 that are bent inwardly to engage grooves 82, 88 in the tube 68 and stem 70, respectively. In an atmosphere-suspended fluid-pressure servomotor arrangement for a braking system, upon manual operation of the lever 62 to move the valve 42 to the right the latter is first unseated and then abuts the adjacent end of the rod 54, any further movement of the lever 62 forces the left end of the detent out of the groove 88, that end of the detent then riding along the stem part 90. Return motion of the levers 62, 52 causes the left end of the detent to slide back on the stem part 90 until it abuts the shoulder formed between the latter and the stem 70 whereupon the valve 42 is seated after which the detent is again forced into the groove 88; any further return force urges the valve 42 to unseat the tubular valve-member 34. The detent ensures that a limited force is applied to the valve 42 to overcome any tendency for it to stick to its seat before the parts 68, 70 are disconnected whilst it enables a much greater force to be transmitted in the opposite direction. Power operation of the brakes does not cause such telescoping of the stem 70 and tube 68.

Title: Non-destructive sensing of a magnetic core
Filed: 1958-06-06
Abstract: 854,153. Magnetic information storage apparatus. SPERRY RAND CORPORATION. June 6, 1958 [Oct. 23, 1957], No. 18225/58. Class 40 (9). [Also in Groups XIX and XXXV] Apparatus for non-destructively sensing the state of a magnetic core 24 comprises a second core 26, also having two stable magnetic states, arranged with its axis of easy magnetization 50 transverse to the axis of easy magnetization 44 of core 24. When the apparatus is used in a digital computer the direction of remanent magnetization 46 in core 24 is designated as a binary " 1 " and direction 48 as a binary " 0." By a process involving heating under the influence of a magnetic field core 26 is made sensitive to a transverse magnetic field while core 24 is relatively insensitive. Core 24 is magnetized along the axis 44 by coincident half currents in conductors 32, 34, providing that there is no inhibiting current in conductor 36 and produces a field in core 26 transverse to the axis of easy magnetization 50. To sense the state of core 24 a current is passed through one of conductors 32, 34 or 36 simultaneously with current in conductors 38 and 40 which may consist of a single alternation. The latter current is chosen to be insufficient to produce switching of the core 26 unless a strong transverse field exists in it. This occurs when the transverse field produced in it by the current in one of the windings 32, 34 or 36 and the transverse field produced in it by the remanent magnetization in core 24 are additive. Hence one direction of magnetization of core 24 is indicated by an e.m.f. produced in read-out winding 42 due to switching of read-out core 26 while the other direction of magnetization is indicated by the failure to produce such an e.m.f. The cores are preferably very thin films of magnetic material having a rectangular hysteresis loop and deposited by the vacuum evaporation or otherwise on glass or other substrates 28, 30 which insulate them from the conductors. The cores may be sandwiched between substrates and the substrates may support a plurality of cores in rows and columns in a memory matrix system. The conductors may be printed circuits etched on the substrates. The core pairs may be arranged in rows and columns to form a memory matrix system. Specification 845,604 is referred to.

Title: Improvements in obtaining olefin oxides
IPC: C25B3/23
Filed: 1966-04-26
Abstract: Monochlorohydrins are produced by dissolving a C2-C4 olefin in an aqueous solution of an alkali metal chloride and contacting the olefin solution at a temperature of not more than 80 DEG  C. with chlorine, withdrawn from a zone where a similar alkali metal chloride solution is electrolysed, thus giving the monochlorohydrin of the corresponding olefin in aqueous alkali metal chloride solution, the concentration of monochlorohydrin in the aqueous alkali metal chloride solution being kept at not more than 1 mole per litre.  The monochlorohydrin in aqueous alkali metal chloride solution may be converted to an olefin oxide by treatment with an alkaline aqueous alkali metal chloride solution, heating the mixture to a temperature equal to or slightly above its boiling point thus distilling off the olefin oxide and leaving a residue having a pH higher than 7, which is passed to the electrolysis zone where it is electrolysed to produce chlorine, an alkali metal hydroxide solution and an alkali metal chloride solution all of which may be reused in the process, and hydrogen as a by-product.

Title: Stepping motors

Filed: 1970-04-16
Abstract: 1299493 Stepping motors SIEMENS AG 16 April 1970 [17 April 1969] 18298/70 Heading H2J A stepping motor has a rotor in the form of a permanent magnet, and is fitted with Hall generators Hx, Hy, whose magnetic fields are provided by the rotor, connected to the control circuit shown so that, when Hx and Hy are supplied with control voltages via R33, R34, R32, the circuit is biased to retain the rotor in its rest position when the supply voltage is restored, until control signals are applied. The outputs of generators Hx, Hy, mounted adjacent the X, Y windings of the motor (Fig. 1, not shown), spaced 90 degrees apart about the rotor axis, are fed to the bases of transistors T5, T6, and T7, T8 respectively, acting as differential amplifiers providing biasing signals to determine which one of each pair of transistors T1, T2; T3, T4 will be initially conducting. The windings X, -X, Y, -Y are energized in pairs, giving four positions of the rotor, Fig. 3 (not shown), which also displays the output voltages U x , U y  of the Hall generators as a function of rotor position. When windings X, Y are energized, transistors T 1  and T 3 , of the bi-stable pairs T 1 , T 2 ; T 3 , T 4 , are conducting, and point L is at the potential P. Capacitors Cl and C4 are fully charged, points V x  and V y  being at low potential due to the connections via R23 and R22 to terminals 9 and 10 of the windings X, Y, whereas C2 and C3 remain essentially uncharged, via -X and -Y are not energized. When the switch K is closed the resulting negative pulse can only pass to the bases of T1 and T4, since D2 and D3 are reverse biased, resulting in the switching off of T1, and via D6 the switching on of T2. T4 is already switched off. D5 ensures that the change is stable. Similarly sequences of negative pulses on the line from L cause the energizing of the windings to pass through the sequence X, Y; -X, Y; -X, -Y; X-Y. corresponding to anticlockwise rotation of the rotor. By interchanging connections V x , V -x  and V y , V -y  respectively, the sense of rotation can be reversed.
