Patent GB-760516-A (GB)
Abstract: 760,516. Electromagnetic couplings with magnetisable liquid. ENGLISH ELECTRIC CO., Ltd. July 22, 1955 [April 23, 1954], No. 11795/54. Addition to 720,468. Class 35. An electro-hydraulic pump or motor operates by the adhesion of a magnetisable liquid to a magnetic rotor under the influence of a magneitc field, the liquid flow being controlled by an adjustable vane in the machine. In the axial form, shown, a pair of magnetic discs 13, 14 consisting of magnetic segments 17 separated by non-magnetic spacers 18, are spaced by a non- magnetic ring 15 so that flux from a magnet 32 has to cross the gap 16 between the discs, thus solidifying the liquid and causing it to rotate with the discs. Magnetic liquid, e.g. magnetic dust in oil, enters at port 23 and leaves at port 22, the rate of flow for pumping or motoring is controlled by means of an adjustable vane 26 which serves to block the duct 16 between the magnetic discs to a greater or less extent. A modification is described in which the magnetic rotor consists of concentric cylinders carrying radial flux, the vane moving axially into the duct. Multiple machines are described.

Patent GB-808192-A (GB)
Abstract: 808,192. Calculating - apparatus. NATIONAL CASH REGISTER CO. June 13, 1957 [July 26, 1956], No. 23187/56. Class 106 (1). In a motor-driven calculating machine having amount keys all of which are partially depressible for the purpose of controlling differential actuating mechanisms and fully depressible to initiate a machine operation, a common member is actuated on full depression of any key and, by means of mechanical connections, operates the starting mechanism of the machine. The mechanical connections replace the electromechanical arrangements having the same purpose described in Specification 710,318. On full depression of a key in any one of several denominational columns of keys, a slide 2 associated with that column is cammed forwardly and rocks a common bail 6 against the action of an adjustable spring (not shown). A tail 10 of the bail thereupon releases a lever 11 to the action of a strong spring 19. A lug 20 of a trip lever 14 overlies an arm of the lever 11 and so the trip lever 14 is also rocked to actuate known mechanism which closes a switch in the motor circuit and engages a one-revolution clutch connected between the motor and the mainshaft. During the ensuing machine operation, a cam 28 is rocked and shifts a link 23 rearwardly to restore the lever 11 so as to enable the clutch to be disengaged, and the motor to be de-energized, at the end of one revolution. The lever 11 is then relatched by the tail 10 of the bail 6. A hand-lever 33 may be raised to cause a stud 34 therein to engage in a cam-slot in one arm of the lever 11 so as to maintain it in its inoperative position, thus disabling the amount-key machine release mechanism.
