Abstract: 1,218,985. Broaching; generating; grinding. MINISTER OF TECHNOLOGY. 20 May 1969 [20 Feb., 1968], No. 8181/68. Headings B3C, B3D, B3K, B3L and B3T. A method of machining in or on a workpiece, comprises rotating a cutter or grinding wheel of non-circular multi-arc form about its axis, and either rotating the workpiece about an axis parallel to and fixed relative to the cutter axis and in the same direction at a related speed, or giving the two the same relative motion by turning the axis of the cutter in the opposite direction around the workpiece axis. When machining a square bore of side 2l, and diagonal 2R, Fig. 4a, the multi-arc cutter has a length R, is rotated about its axis B at twice the rotational speed of the workpiece about its axis A. The machining could be carried out by fixing the workpiece and causing axis B to travel about axis A in reverse direction in a circle of radius ¢R. Four such cutters may be used, Fig. 6 (not shown). A regular hexagonal bore may be produced by a cutter having 3 arcs, Fig. 5a, or three such cutters, Fig. 7 (not shown), may be used. In general, a cutter with N arcs will produce a figure having 2N sides if the 2: 1 ratio of rotational speeds is maintained. The cutters may be of oval form, Fig. 8 (not shown). A double square, Fig. 9 (not shown), or a double hexagon, Fig. 10 (not shown), may be produced by two cutters. A male workpiece can be produced by an identical or complementary shaped cutter, Figs. 1 and 2 (not shown). A tool for cutting a square hole comprises a spindle 1, Fig. 12, for attachment to a drilling machine, upper and lower crossheads 2, 3 secured together and carried by spindle 1. Cutter spindles 7, 8 rotatable in the crossheads and carrying gears 11, 12 which mesh with an internal gear 10b so that the cutter spindles rotate at twice the speed of spindle 1. A single cutter may be used, in which case spindle 7 is replaced by a balancing rod. In a modification, spindle 17 carries a roller of diameter "l" which rolls inside a like-sized bore in a jig under the workpiece. In a further modification, an adjustable tool for cutting square bores of different sizes comprises a turn buckle 25, Fig. 13, so as to vary the radial positions of cutter spindles 7, 8. The cutters may have end cutting edges. They may be used in a jigging type machine which provides for reciprocating movement of broach type cutters as well as rotation. It is stated that an external hexagonal shape can be generated by using six equally spaced cutters.

Filed: 1975-02-11
Abstract: 1497863 Multipliers GENERAL ELECTRIC CO Ltd 11 Feb 1975 [25 Feb 1974] 8383/74 Heading G4A A multiplier for multiplying together two numbers expressed in powers of the radix minus two is formed by an array of identical cells each including an adder 2, two AND gates 1, 3 and an exclusive OR gate 4. The two numbers to be multiplied are applied to inputs b 0 -b 3  and a 0 -a 3  respectively, the output being derived from outputs c 0 -c 7 . Except at the periphery of the array the AND gate 1 of a cell receives inputs from one of the inputs b 0 -b 3  and one of the inputs a 0 -a 3 , and provides an output to the respective adder 2. The addder 2 also receives a sum signal from the adder 2 of the next cell down and to the left and a double carry signal from the AND gate 3 of the second cell to the right. The adder 2 supplies a sum output to the next cell up and to the right and a carry output to gates 3, 4 of its own cell. Reception by exclusive OR gate 4 of a single carry signal, either from the adder 2 of that cell or from the exclusive OR gate 4 of the next cell down and to the left causes a carry signal to be supplied to the next cell up and to the right. Reception by AND gate 3 of carry signals from both the adder 2 of that cell and from the exclusive OR gate 4 of the next cell down and to the left causes a double carry signal, representing the second higher power of minus two, to be supplied to the adder 2 of the second cell to the left. The carry from exclusive OR gate 4 in each of the periphery cells which provide the output signals c 0 -c 5  is applied to each of the next two higher powers of minus two as, for numbers expressed in powers of the radix minus two, 001+001=110.

Title: Improvements in or relating to electrical measuring circuit-arrangements
IPC: G01R27/32
Filed: 1948-03-22
Abstract: 640,600. Frequency measurements; cathoderay oscillographs. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 22, 1948, No. 8399. Convention date, March 25, 1947. [Class 37] In order to facilitate frequency analysis of a voltage wave form, a wave form similar thereto but of a lower frequency is derived therefrom. The high-frequency oscillation a, Fig. 1, to be examined has a fundamental frequency fs and is mixed with phase-modulated impulses b having a modulation frequency fm and a central frequency fh=fs/n. The generator furnishing the impulses b is synchronized by the oscillation a so that one impulse occurs in every n cycles of fs. This generator is phase-modulated with a low-frequency fm causing successive impulses to coincide with different ordinate values of the oscillation a. Together with the voltage fs the impulses are supplied to a mixing valve which produces a sequence of impulses which are amplitude-modulated in accordance with the variation of the oscillation a and phasemodulated with the frequency fm. By means of a low-pass filter the measuring frequency may be filtered out as a fundamental frequency with a large number of harmonics. This is an image of the oscillation wave form a at a lower frequency. Fig. 4 shows the application to an oscillograph. The oscillations to be reproduced, which originate from a source S, are supplied to a mixing valve M and to an oscillator O which is synchronized by the oscillations to be reproduced. The synchronized oscillations are modulated in phase by 50-cycle mains in a modulator Mod and are also supplied to the. mixing valve M through a device I which converts the modulated oscillations into impulses. The output of the mixing valve M is fed through a low-pass filter LP and a lowfrequency amplifier A to one pair of deflecting plates of a cathode-ray oscillograph KRT, the other pair of deflecting plates being connected to the 50-cycle supply to form a time-base. Two signal voltages may be reproduced simultaneously by supplying them to a common mixing valve through two channels which are alternately blocked by an alternating voltage in quadrature with the modulation voltage.

Abstract: 505,861. Colour photography. DU PONT FILM MANUFACTURING CORPORATION. March 18, 1938, No. 8472. Convention date, March 20, 1937. [Class 98 (ii)] Relates to the production of independent colour separation records from an original bearing two or more such records inseparably superposed on one side of a support which comprises the steps of making an intermediate copy of the superposed records (positive if said records are negatives, and vice versa), chemically eliminating one record from the original, and forming an independent copy of the eliminated record by copying from the remaining record or records and the intermediate copy in register. According to the invention, the elimination of one of the records is effected after the records have been developed 'to silver images, by bleaching all the records to silver salts, redeveloping all but the innermost record by controlled development, and dissolving away the undeveloped silver salts forming the innermost record. In one example, bi-pack film is used, the front film carrying a bluesensitive emulsion dyed with a removable yellow dye, and the rear film carrying a redsensitive emulsion covered by a layer dyed with a removable red dye and a green sensitive enulsion. After making the intermediate copy of the red and green images combined, these images are bleached, for example with ammoniacal potassium ferricyanide, potassium ferricyanide and potassium bromide, or cupric bromide. The controlled development of the outer image may be achieved either by using a concentrated developer or by adding alcohol, glycerine, or sugar to the developer to restrict its action.
