Title: Improvements in or relating to hydraulic servo-control means for machine tools
Inventor: ORLOFF GEORGE
IPC: F15B9/08
Filed: 1959-08-04
Abstract: 935,329. Fluid-pressure servomotor control systems. NORMALAIR Ltd. Aug. 2, 1960 [Aug. 4, 1959], No. 26527/59. Class 135. A control means for a machine tool, such as a lathe, comprises an hydraulic input valve stage 1, an hydraulic output valve stage 18, and an hydraulic feed-back valve stage 13 varying the signal transmitted to the output valve stage from the input valve stage in accordance with the output signal from the output valve stage, wherein the hydraulic input valve stage embodies a closure member 10 operatively associated with one or more nozzles 11 discharging fluid, the closure member being under the control of a stylus 3 adapted to be moved by a cam 2, the nozzle being in controlling communication with the hydraulic output valve, which controls an actuating piston 28 operatively associated with the feed-back valve, and the degree of obturation of the nozzle by the closure member 10 being responsive to signals generated by the hydraulic feed-back valve. The closure member 10 is fixed to the stylus 3 which is supported by two diaphragms 4, 5 carried by a housing 1, the stylus being spring-urged into contact with the cam 2; the housing is provided with a cylinder 7 which is movable, against the action of a spring 12, over a piston 8 rigidly secured to a stationary part of the machine. The closure member 10 co-operates with a nozzle 11 through which a fluid-pressure medium is fed. In operation, upon rotation of the cam 2, the stylus is moved, thereby varying the distance between the closure member and the nozzle and thus the fluid-pressure in a pipe leading to the output valve 18; the fluid pressure then acts on a ball 16 which moves a closure member 17 so as to allow the fluid-pressure medium to act on one or other end of a spool-valve 25 and thus be fed into the cylinder 27 of the actuating piston 28 connected to a tool of the machine. Movement of the piston-rod 29 causes a cam 30 secured thereon to move over a stylus 31 connected to a closure member of the feed-back valve stage 13 and so vary the pressure in a line connected to a nozzle 35 and the cylinder 7 of the input valve stage 1; the housing 6 is then moved to reset the nozzle relative to the closure member 10. In a modification, the housing 6, Fig. 2, is stationary and the closure member 10 is actuated by fluid-pressure acting on a ball 8a secured by a rod 10a to the closure member, and the stylus 3 acts on the closure member through a spring 3a. Specification 928,802 is referred to.
Patent GB-746474-A (GB)
Title: Improvements in or relating to dyeing
Inventor: ROFF ERNEST AVERY
IPC: D06P1/653
Filed: 1952-10-23
Abstract: In the dyeing of superpolyamide or proteinaceous textile materials with acid or acid-mordant dyestuffs, well penetrated and level dyeings with good exhaustion of the dyebath are achieved by incorporating in the bath a water-soluble salt of an alphamonohalogen - substituted saturated mono-carboxylic acid of 2-4 carbon atoms. The salt liberates free acid in hot aqueous solution and thereby ensures a gradual and uniform rduction in the pH of the bath.  The salt, which may be formed in situ by neutralization of the free acid, is preferably sodium monochloracetate, but sodium salts of other acids or potassium, lithium, ammonium, calcium, strontium and barium salts may also be employed, as also may acids in which the halogen is bromine or iodine.  The process is applicable to nylon and wool in the form of fibres, yarn, slubbing and piece goods.  When dyeing nylon fibres the bath should contain sufficient ammonia or other alkaline substance to render the initial pH value sufficiently high, e.g. as high as 10, to promote a uniform dyeing action. Numerous examples are given, in one of which wool is dyed by the metachrome method in an enclosed circulating liquor machine.

Patent GB-1279355-A (GB)
Title: Arithmetic and logic unit
IPC: G06F7/00
Filed: 1970-06-03
Abstract: 1279355 Arithmetic and logic units INTERNATIONAL BUSINESS MACHINES CORP 3 June 1970 [12 June 1969] 26720/70 Heading G4A An arithmetic and logic unit comprises a logic module for each bit order position of the operands having two logic means the first being configured as a subtracter and responsive to the second operand and an arithmetic control signal to control the second logic means to modify or not the first operand. In a first embodiment, two operand registers each hold four data bits and a parity bit and feed four modules each as in Fig. 2. The inputs on the left in Fig. 2 are the two operand bits A i , B i , the carry input from lower order CARRY  i-1 , and control signals of which COMPL A i , COMPL B i  permit the operand bits to be complemented, and CHANGE r i  permits the result output R i  of the module to be complemented. The control signal SUB is used in binary and (binary-coded) decimal addition and subtraction, addition being by complemented subtraction. In the decimal cases, a high order carry causes six correction by energizing some of the CHANGE r i  inputs to modules in dependence on some of the r i  outputs. In decimal (true) subtraction, a high order carry causes recomplementing of the result to get the correct answer, by putting the result and one (in the case of the first digit) in the two registers and using complemented subtraction. Other operations performed by the unit are (control signals required at the module inputs being specified in brackets): AND (AND), OR (OR), pass operand B (AND, OR), pass operand A (no control signals), test bits on viz test whether A i  is on for each B i  which is on (OR), test bits off viz test whether A i  is off for each B i  which is on (AND, COMPL B i ), sets bits on viz set each A i  on if corresponding B i  is on (OR), set bits off viz set each A i  off if corresponding B i  is on (AND, COMPL B i ), EXCL-OR (AND, OR, COMPL B i ). For the test bits operations, an OR gate (not shown) receives the CHANGE A i  outputs of the modules to indicate the result (on output means false). A binary compare is performed by (true) subtraction with examination of whether the result R i  is zero (off) and whether there is a carry out. EXCL-OR (OE) trees (not shown) are used for checking the complementing of B, (using the B i  COMPL outputs of the modules), predicting a parity bit for the results R i  (using the CHANGE A i  outputs of a duplicate set of modules), and parity checking the results R i . The high order carries of the two sets of modules are compared as a check. Two or more of the above 4-bit arithmetic and logic can be connected in parallel. A modification is disclosed having two operand registers each holding 8 data bits and a parity bit. In decimal arithmetic, the lowest order 4 data bits are used for the decimal digit, the other data bits indicating the sign (by one of them being 0 or 1 according as the sign is minus or plus respectively, the others being 1 in either case).
