Abstract: 1,265,376. Digital electric calculator. OMRON TATEISI ELECTRONICS CO. 2 May, 1969 [14 May, 1968; 17 May, 1968 (2); 11 June, 1968; 22 June, 1968; 26 June, 1968; 30 Oct., 1968], No. 22522/69. Heading G4A. Digital electric calculator has a plurality of shift registers connected in series with each other and with an adder to form a loop, gates being provided connecting various registers to vary the size of the loop. As shown, four registers R1-R4 are provided, register R4 being in two parts 1R4 and 2R4, the latter having four binary stages to hold a binary-coded decimal digit. The registers feed an adder A, gates G2, G4 allowing the contents of registers R4, R5 to be fed simultaneously to the adder. The result from the adder is fed back to register R1 via gate G8. A gate G6 feeding the contents of 1R4 to R1 is used to cause a shift right of the contents of register R4. A fourstage register placed in parallel with gate G7 and controlled by a further gate can be used to provide a shift left. A display can be fed from register 2R4, each digit received being decoded by matrix MX to feed a signal to an appropriately enabled indicator DT. Alternatively, the contents of each register may be passed by an appropriately enabled gate to a further register feeding the matrix. Subtraction is performed by adding the complement of a number, multiplication by repeated addition and division by repeated subtraction. Read only microprogramme store (Fig. 7).- Diode matrix MX, receiving a signal F, enables one of the lines 1-15 passing to matrix MX2. A signal A or D enables one of the transistors QA, QD to apply a signal -E to the transistor Q1-Q4 enabled by a timing pulse ta-td. A line gi and g m  in matrix MX3 is enabled depending on the cross-over points between the lines enabled by the matrix MX2 and the timing pulses.

Abstract: 1,265,619. Delta encoders. INTERNATIONAL BUSINESS MACHINES CORP. 12 Oct., 1970 [14 Oct., 1969], No. 48353/70. Heading G4H. A delta encoder for encoding an analogue input signal comprises an integrator for generating at any given sampling time a comparison signal representative of the value of the input signal at the preceding sampling time for subtraction from the value of the input signal at the given sampling time and a current control circuit including a transformer T.I. through which charge current flows to and discharge current flows from the integrator in response to encoder outputs of first and second binary values respectively, the transformer ensuring the equality of the charge and discharge currents. In the absence of an input signal, the pulse generator of the encoder emits a sequence of alternate " 1 " and " 0 " bits at a rate determined by clock pulses. When the generator emits a " 1 " bit diodes D1, D3 are blocked and the integrator is charged via a diode D2 by the current induced in the transformer secondary due to the clock pulses applied to the transformer primary. When the generator emits a " 0 " bit the diodes D2, D4 are blocked and the integrator discharges via the diode D3. Since both the charge and discharge currents flow through a transistor T1 and the transformer secondary winding their equality is ensured thereby minimizing idle channel noise. In a modification the circuit connected across the diagonal of the bridge D1-D4 is replaced by a current limiter. Any remaining drift leading to idle channel noise is compensated by delay circuits Cp, Cq which automatically adjust the charge or discharge period of the integrator by adjusting the " OFF " or " ON " period of the generator.

IPC: H02K7/11
Filed: 2000-01-11
Abstract: A magnetic induction drive for a rotatable driven member in a sealed housing, in particular, a shaft-mounted blade in a blender cup or a shaft-mounted blade in an ice shaver, uses a comparatively thin circular drive plate of a magnetizable material with circumferentially arrayed poles enclosed within a housing secured to a drive shaft. A brushless d.c. motor in a base separate from the housing has a rotor formed as an array of pie-shaped permanent magnet regions that interact with an electronically controlled, rotating electromagnetic field produced by a ring of stator coils. A second such permanent magnet is coupled to rotate coaxially and in unison with the rotor, with poles of opposite polarity aligned and adjacent one another. A steel disc is sandwiched between and bonded to the rotor and the second permanent magnet. The magnetic field (lines of flux) of the second magnet extends axially away from the rotor to induce magnetic poles of opposite polarity in the drive plate. This second magnet-to-plate magnetic coupling operates across a closely-spaced gap that includes the bottom wall of the base, the upper wall of the housing, and air gaps between these walls, and the plate and the second magnet. A gear train assembly can be coupled to the drive shaft to increase or decrease the amount of torque transmitted from the drive plate to the driven member.
