Title: Electrical calculating apparatus
IPC: G06J1/00
Filed: 1955-02-11
Abstract: 770,487. Digital electric calculating apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 11, 1955 [Feb. 16, 1954], No. 4127/55. Class 106 (1). An electronic calculating apparatus comprises means settable to register a number, potential divider means controlled by the number registering means to produce an analogue voltage presentative in magnitude of the registered number, means for producing a gating voltage representative in duration of the magnitude of said analogue voltage and applying said gating voltage to a gating apparatus associated with a pulse source so that pulses equal in number to said registered number are emitted by said source. Two four-digit binary numbers A and B are set up on switches S1, S4, S8 and S1<SP>1</SP>, S2<SP>1</SP>, S4<SP>1</SP>, S8<SP>1</SP> respectively, Fig. la, the switches, which may be electronic, each being shown registering zero, and as a result the potential of a line 10 rises to a value representative of the sum of the two numbers A and B. This voltage is applied via a diode V3 to a " phantastron " circuit comprising tubes V1 and V2, Fig. 1b, which when a positive triggering pulse is applied to tube V2, produces, at the cathode of tube V2, a negative output pulse, having a duration proportional to the potential of line 10, which is shaped and inverted by triodes V6, V7, V8 and applied to a tube V4 causing a multivibrator, constituted by tubes V4 and V5 to oscillate for the duration of the output pulse and produce a group of pulses equal in number to the sum of the numbers A and B. The output pulses from the multivibrator are shaped by triodes V9 and V10 and passed to a counter. Thus, as a result of applying a triggering pulse to the phantastron circuit a group of pulses equal in number to the sum of the numbers A and B is passed to a counter. This adder could be used as one denominational order of a binary-coded-decimal adder, in which case a carry digit C could be added to A and B by means of a switch S1<SP>11</SP> as shown. In a second embodiment for multiplication (Fig. 2, not shown), two registers similar to registers A and B are each associated with a phantastron circuit and a multivibrator in a manner similar to that in which registers A and B are together associated with the phantastron circuit and multivibrator shown in Fig. 1, and the output pulses produced by the first multivibrator are each used as a triggering pulse for the second phantastron circuit, the final output from the second multivibrator (which operates at a highei frequency than the first) being a group of pulses equal to the product of the numbers registered in the two registers. An example of suitable component values is given.

Title: Improvements in mechanical systems for the transmission of power in oscillating form
IPC: B06B3/00
Filed: 1924-02-20
Abstract: 223,852. Schieferstein, H. Feb. 20, 1924. Machinery, utilizing inertia to obtain movements in.-Elastically constrained masses or mechanical systems oscillating with pronounced natural frequency when energized through " loose " or yielding couplings by driving mechanism such as a crank or eccentric rotating in unison therewith, such as described in Specifications 188,633 and 237,934, are provided with elastic constraining means so graduated that, as the amplitude of oscillation increases, disproportionately increased stresses are produced at the ends of the stroke and the motion is characterized by rapid accelerations and retardations with intermediate periods A-B, C-D corresponding substantially uniformly to the desired working velocity, as indicated by the velocity and spring tension curves, I, II, respectively in Fig. 3. For example, a mass a, Fig. 2, supported by the free ends of springs b, fixed to a base m, is oscillated by a crank g and connecting rod h acting-through a pivoted lever v constrained at its upper end by springs k. When the crank g is rotated, the lever v is rocked, the motion being gradually taken up by the mass a. As the amplitude of oscillation of the mass a increases, bending of the springs b brings other springs b<1>, b<2> successively into action at each end of the motion, thereby producing the effects indicated above as distinguished from motion according to a sine curve. The invention is stated to be applicable for use in machines such as reciprocating saws, mowing machines with reciprocating cutters &c. The natural frequency of the system increases with the amplitude of oscillation. The oscillatory mass a may be constrained by volute, helical or other springs, or by gas or air cushions, the elasticity of which may be regulated by control valves &c. Various forms of " loose " or yielding coupling means between the driving mechanism and the oscillatory system may be used, as described in Specification 237,934, being classified into elastic couplings, Fig. 7, inertia couplings G, Fig. 8, friction couplings F, Fig. 9, in which the yielding effect is obtained by slip, and intermittent or ratchet couplings. In the arrangement shown in Fig. 4, the mass a is arranged between double volute springs b the resistance of which increases disproportionately as the coils are telescoped, the drive being from an eccentric g through an adjustable connection to a lever k. The springs constraining the mass a may be of triangular or other forms in which the part adjoining the point of attachment to the base, is greatly overdimensioned and bending is mainly at the upper part until strongly loaded. The oscillatory systems may be tuned to the speed of the driving means by varying the elastic constraint or the masses used. The free ends of constraining springs, such as b<1>, b<2>, may be furnished with balls or rollers to diminish damping effects.

Abstract: 995, 076. Photo-electric determination of position. ERNST LEITZ G.m.b.H. Feb. 4, 1964 Feb. 23, 1963], No. 4658/64. Heading G1A. Apparatus for determining the position of a mark comprises means for scanning the mark to produce a train of pulses the spacing of which is indicative of the mark position, a bi-stable stage controllable alternately from two inputs to which the pulses are fed, means to indicate the pulse time ratio, and means to ensure that the indication has the correct sign. The mark comprising a transparent slit in an opque mark II is illuminated by a lamp 14, and the light passing through is chopped by an oscillating slit 12 before falling on a photomultiplier 15. The output pulses of photomultiplier 15 are squared in a Schmitt trigger 17, differentiated at 18 and fed to the inputs 19<SP>1</SP>, 19<SP>11</SP> of a flip-flop 20. The output of flip-flop 20 is a pulse train with mark/space ratio indicative of the deviation of the mark position from a datum, the indication being converted into a D.C. signal by an integrator 21, 22 and displayed on an instrument 23. To ensure that the output of flip-flop 20 is always of the correct phase, signals from the slit drive means 13 open an AND gate 24 so that flip-flop 20 is only operated by input 19<SP>11</SP> when the slit is moving in a given sense. In a modification, both leading and trailing edges of the photomultiplier are used, by duplicating the differentiator 18, AND gate 24 and the flip-flop 20. The integrator 21, 22 is connected to both flip-flops.
