Title: Improvements in precision machine tools
IPC: B23Q23/00
Filed: 1955-01-21
Abstract: 780,608. Screw-cutting by turning. CRAVEN BROS. (MANCHESTER), Ltd., and THOMAS, A. K. Nov. 29, 1955 [Jan. 21, 1955], No. 1866/55. Class 83 (3). In a machine-tool, corrections to compensate for lead-screw inaccuracies are made to the movement of a slide i, such as the tool-slide in a screw-cutting lathe, by a corrector-bar a, the movements being positive in either direction of traverse of the saddle carrying the slide. The corrections are applied to the slide i through a lever b pivoted at c and having two knife-edges d, e. The edges co-operate with faces f, g on a plunger h mounted in the slide. One or other of the faces is brought into operative position by manual rotation of a pinion j, which also moves a plunger k within a lever m pivoted at m<SP>1</SP>. The lever m is acted upon by a spring o through a link n. Thus, simultaneously with the movement of the plunger h to reverse the effect of the lever b, the effect of the spring o on the lever m is reversed. In a modification, the spring is replaced by reversible hydraulic-means. Specification 765,939 is referred to.

Title: Improvements in digital data storage devices for electronic computers and the like
IPC: G06F9/355
Filed: 1958-01-22
Abstract: 866,599. Digital data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 22, 1958 [Jan. 23, 1957], No. 2185/58. Class 106 (1). An electric data storage device comprises a plurality of data storage elements, individual means each associated with a corresponding element and successively operable for partially conditioning this element to read in and/or read out data stored therein, means for arresting the successive operation of said conditioning means at a selected one of said elements and means operative simultaneously with a restart of said successive energization to activate further means for applying a second partial conditioning to all said elements whereby elements beyond said selected one are successively completely conditioned. As described, a conventional magnetic core matrix store, Fig. 1e, comprising a plurality of 4 x 80 storage units, is controllable by plug connections so that two binary-decimal numbers, one in each of the two storage units, can be read out, added, and their sum entered in place of one of the numbers, even though the two numbers are not in corresponding fields. A programme control unit, Fig. 1a, is also provided, settable by plug connections, so that after one operation, for example an addition, has been performed, a second, which may be a further addition or a transfer, follows automatically. The main control equipment comprises two chains of eighty triggers C1, C2 ... and C11, C12 ..., Fig. 1c, which are driven alternately to advance from right to left an on state along them and associated with which is a set of eighty hubs 166-1 to 166-80. Initially plug connections are made from those two of the set of eighty hubs that correspond to the positions in the store of the two units digits of the two numbers that are to be added to hubs 165-2 and 167-2, Fig. 1a. Plug connections are also made to those two of a group of hubs 164-1, 164-2 ... 164-80, Fig. 1e, which correspond with the particular two storage units holding the two numbers that are to be added. The apparatus is then started by closing a contact 105, Fig. 1b, and the on states in the two chains C1 and C<SP>1</SP> 1  are progressed. This continues until the on state in one of the chains reaches the stage corresponding to the units digit of one of the two numbers; advancement of this chain then ceases until the other chain reaches the stage corresponding to the units digit of the other number (these two stages are recognized by virtue of the plugged connections), advancement of both chains then proceeds to cause the read-out of the two numbers involved into an adder 227, Fig. 1d, and the read-in, in place of one of the two numbers of their sum, the addition and the read-in of the sum being done in a digit-by-digit manner, first the units digits are read and their sum is read-in to the store, ,then the tens digits and so on.

Title: Process for treating the sound track in multi-layer cinematograph film
IPC: G03C7/24
Filed: 1939-01-23
Abstract: 524,114. Multicolour kinematograph films bearing sound records. KODAK, Ltd. (Eastman Kodak Co.). Jan. 23, 1939, No. 2267. [Class 98 (ii)] The silver sound image in multilayer material, bearing also silver colour component picture images which are to be differentially processed to colour, is converted by local application of a gold, palladium, platinum, or mercury toning bath to an image which will survive the baths subsequently applied to process the picture images. Formulae for the toning baths are given. Spreading of the toning solution may be prevented by including loading agents therein as described in Specification 454,622 or by providing by pre-exposure between the sound and picture areas a silver line which exhausts the spreading solution. When gold toning is used, the bath for final silver removal may be one containing weakly-acid ferrocyanide, or cupric chloride and potassium bromide. The picture images may be processed by reconverting the silver to silver halide and colour developing ; or by reversal, as by removing the silver and colour developing the residual silver halide. In the latter case, the initial general development to produce the silver picture and sound images may be stopped before completion in order to apply the toning bath to the sound image thus far developed; thereafter the sound area is uniformly exposed to light and the silver development is completed, the silver so formed in the sound area being removed subsequently in the reversal colour processing. The sound image may be formed in one or more of the picture layers, and/or in a separate overcoated layer, and may be produced by exposure with blue light only. The invention may be applied to colour films processed as described in Specifications 440,032, 447,092 and .507,841.

Abstract: 777,817. Measuring humidity electrically. ELLIOTT BROS. (LONDON), Ltd. Jan. 29, 1953 [Jan. 29, 1952], No. 2428/52. Class 40 (1) Apparatus for determining the relative humidity of a gas comprises two Wheatstone bridges, one for measuring the dry temperature T and the other for measuring the wet temperature T 1  of the gas, and means for obtaining an indication of the ratio (T-K)/(T 1 -K 1 ) where K and K 1  are predetermined constants, this indication being proportional to the relative humidity of the gas. As shown, a resistance thermometer element 6 measures the dry temperature T in a first bridge network A, and an element 16, covered by a moistened sleeve, measures the web temperature T 1  in a second bridge network B, each bridge being fed with an equal A.C. voltage. The output of bridge A is fed across a potentiometer 11, through a resistance 12, and the output of bridge B is fed across part of this potentiometer 11 as determined by the slider 19. The difference between the output from B and that portion of the output of A determined by the slider 19 is fed to one winding of a 2-phase motor 21 via an amplifier 20, and the motor 21 drives the slider 19 to a position of minimum combined signal, this position being indicative of the ratio (T - K)/ (T 1 - K 1 ), and therefore of the relative humidity. The constants of the bridge circuits are chosen so that the outputs of the bridges represent T and T 1  in degrees Centigrade, and K, K 1  are each approximately - 20‹ C., the exact values being determined by the specific temperature range over which the apparatus is to be used. The motor 21 may also drive a recording instrument, or control valves, heaters, &c. to adjust the relative humidity as required. The bridge connections 8, 9, 10 are such as to compensate for. variations in ambient temperature. The bridge may alternatively be fed with D.C. and the outputs compared by a crossed-coil ratiometer.
