Title: High speed adder
IPC: G06F7/50
Filed: 1964-06-17
Abstract: 1,040,778. Parallel adders. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 17, 1964 [June 20, 1963], No. 25070/64. Heading G4A. To increase the speed of operation of an adder, the numbers to be added are dealt with in a plurality of sections and a provisonal sum is formed for each section with the assumption that the input carry from the previous section is zero. A modifying circuit then modifies the provisional sum according to the true value of the input carry. Fig. 1 shows diagrammatically one such section operating on six bit positions x1-x6, y1-y6 of the numbers x and y to be added. In circuit 1i the signals d# = x#y# (AND), and e# = x# # y# (EXCLUSIVE OR) are formed. From these signals provisional sums Z‹K are formed and these are applied to the modifying circuit 3i together with the input carry Ci and the signals e#. In this circuit the true sums Z# are formed. The circuit 4i forms the output carry Ci+1 and also terms Pi = dq # eqdq-1 # eqeq-1dq-2 # ... #eqeq-1... ep-1dp and Qi = eqeq-1 ... ep where the section extends from the pth to the qth positions of the numbers to be added. These terms are applied to circuit 5 to form the end-around carry for use in subtraction by ones complement addition. Fig. 3 (not shown) shows the logical circuitry used to perform the above operations. The equations which the circuitry represents are listed in Figs. 2a and 2b (not shown), and described in the Specification.

Title: Improvements in and relating to magnetic transductors
Inventor: SHERLOCK JAMES
IPC: G05F1/32
Filed: 1956-08-17
Abstract: 831,791. Magnetic amplifiers. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. Nov. 14, 1957 [Aug. 17, 1956], No. 25233/56. Class 40 (9). [Also in Group XXXV] An auto-self-excited transductor, in which the source of A.C. excitation 2, 3 energizes a load 1, a load rectifier 4, and the transductor winding 5, connected in series ; provides a path for control current by shunting the load rectifier with a series connection of manually variable inductor 7 and a rectifier 6. In one half-cycle of the A.C. source the transductor, which uses a core with a rectangular hysteresis loop, is driven to saturation and in the following half-cycle current is shunted round the load rectifier and through at least part of the transductor winding 5 to reset the core to an extent determined by the impedance of the variable inductor 7. By making a tapping 8 for the reset path it is stated that a greater range of controlled output current is obtained in face of the voltage drop across inductor 7 when this is set to a minimum; alternatively, the voltage drop across inductor 7 may be overcome by adding a voltage in series with the inductor. Two half-wave circuits may be connected back-to-back with the load and variable inductance control in common to provide a full-wave output, (see Fig. 2, not shown). The inductor 7 may comprise a coil 11 contained in a casing 12 of magnetic material with a plug 15 on a shaft 17 which is slidable in a tube 19. A spring 20 normally holds the plug 15 withdrawn from the coil and casing to the maximum extent permitted by a washer 21 on the shaft 17 and an abutment 22 on the tube 19. As a pushbutton 18 is pressed inwards the plug 15 enters the core until it abuts the casing 12 where the coil has its maximum inductance. The arrangement is intended for an open loop control system where the variable inductance is remote from the amplifier and an induction motor which it controls. Specification 753,356 is referred to.

Class 35 In an electromagnet of the type having an armature which moves co-axially with the winding the armature comprises or is supported by links of magnetic material extending radially from a guided central member towards a surrounding yoke. Fig. 1 shows an armature 9 riveted to a screw-threaded bush 18 on which an adjuster head 19 is fitted. Sector shaped links 13 have their inner ends arranged to be received by recesses formed by the armature flanges 11, 12, while the outer ends of the links 13 are received by a recess 14 formed in the electromagnet housing 5. The links 13 are arranged to provide a substantially unbroken flux path directed radially around the armature axis. Vibration of the links 13 is prevented by a spring 17.
