Title: Sepctrophotometers
IPC: G01J1/24
Filed: 1972-07-12
Abstract: 1414311 Spectrophotometers PYE Ltd 30 Oct 1972 [12 July 1972] 32516/72 Heading G1A [Also in Division G2] In an optical pull spectrophotometer which produces through a servosystem a plot of sample transmittance against wavelength an attenuator is provided which can be adjusted on the one hand to change its lower and upper transmittance limits whilst keeping the same range between these limits and on the other hand to change the range between these limits. The attenuator comprises a wedge formed as a space between two opaque plates 10, 11 mounted on rollers 17-20 on two pairs of parallel tracks 13,14 and 15,16; the wedge may be drawn between two limit positions by strings 38, 39; which are driven by a servomotor, across the light beam, which emerges from an aperture 40. Pulling on end A of a string 28 against a spring 31 with the  other end B of the string 28 anchored opens parallel tracks 15, 16 to change the angle of the wedge, but leaves the spacing of tracks 13, 14 unchanged. Pulling on end B with end A anchored opens both pairs of tracks equally, thus keeping the wedge angle constant. Ends A and B may thus be linked to controls calibrated directly in terms of the "scale expansion factor" of the instrument and its lower transmittance limit respectively.

Filed: 1966-07-20
Abstract: 1,148,735. Digital electric computer. RADIO CORPORATION OF AMERICA. 20 July, 1966 [2 Aug., 1965], No. 32590/66. Heading G4A. A digital electric computer system comprises data bus means, IB, OB, a processor matrix PM having first and second operands and having an output, a utility register UR connected to receive data from the data bus IB and to supply data to the first input of the processor matrix, a scratch pad storage means 50 having a data input, a plurality of storage locations, a data output and means for selectively coupling any desired storage location to said data input and said data output, means to couple the data bus to the data input of the scratch pad storage means, means to couple the output of the scratch pad storage means to the second input of the processor matrix and to the data bus, an intermediate register IR having an output coupled to the data bus, and means to couple the output of the processor matrix to the input of the intermediate register and to the data input of the scratch pad storage means. In operation data may be fed from bus IB via an AND gate 24 to be held in register UR prior to passing via AND gate 20 to the processor matrix, which is a network for performing addition, subtraction, shifting, comparing, masking, &c. A second input to the matrix may come from a register DR<SP>1</SP> fed from the scratch pad memory, or may omit the register DR<SP>1</SP>. The register DR<SP>1</SP> may also be fed via AND gate 26 from the bus IB. If read-out from the memory involves destruction of the data then the data in register DR<SP>1</SP> can be read back into the memory via AND gate 30. The output of the matrix can pass via AND gate 40, register IR and AND gate 42 to the bus line OB or via AND gate 44 to the scratch pad memory. The memory may consist of a stack of magnetic cores together with windings and circuits for reading and writing or may comprise a set of flip-flop registers I 1 -IV 3  for storing several bits of binary data. The flip-flop registers may contain a programme or processor information, each set of registers containing instruction registers, programme counter registers, data accumulation registers, &c., so that programme change during an interruption can be carried out rapidly without transferring to the main memory which has a much longer memory cycle than the scratch pad memory. The gates described comprise a plurality of units in parallel and allow, at branch and converging paths, the passing of a computer word along different paths or to pass all or a selected portion of a word along any path.

Oct. 31, 1930, No. 32726. Convention date, Oct. 31, 1929. [Class 82 (ii).] Metal tubing is formed continuously from flat steel stock 1 with a bonded coating of copper or a copper alloy on one or both sides by passing the stock first through dies or, as shown, through rolls 3 which form the tubular cross-section, whereafter it passes through the heating chamber 6 of a furnace raised to a temperature of 2100‹ F. by electrical elements 5 so that the copper coating is melted, whereby the seam is brazed and the tube is coated continuously with copper either internally, externally or both. The tube then passes through the cooling chamber 14 of a vessel 10 through which cold water is circulated under control so as to prevent chilling of the copper, and finally to a water spray 15 which is also controlled so as to give desired hardness characteristics to the steel. Both the heating and cooling chambers are supplied with a reducing atmosphere such as hydrogen through a pipe 17. The tube may be single-ply with a butt or lap joint or with a lock seam. Alternatively, the tube may be two-ply formed from a single sheet rolled through 720‹. The coating may be 0À00075-0À002 ins. thick and may be of pure copper or of a copper base alloy such as silver solder containing silver and a small quantity of zinc.
