Title: Improvements in central buffing and draw gear for railway and like vehicles
IPC: B61G9/06
Filed: 1921-06-03
Abstract: 183,018. Spencer, A. June 3, 1921. Combined buffer and draw-gear.-In a central buffing and draw gear for a rail or like vehicle of the type in which the spring arrangements are such that one spring or set of springs are compressed to a limited extent either in buffing or drawing before the other spring or set of springs comes into action, after which both sets of springs are compressed in parallel, the spring or springs b that come into action first are located between an end pressure plate k and an intermediate compression plate h, the pressure upon which is transmitted from the other end pressure plate d through a sleeve g which may be formed in one with either the intermediate compression plate h or the last mentioned end pressure plate d, a compression plate f for the other spring or set of springs a being mounted to slide on the sleeve g, and the preliminary compression of the spring b that comes into action first being limited by one or more sleeves o, n located between the sliding plate f and the end compression plate k. The springs b that first come into action are made more sensitive to resist light loads than the other spring a that comes into action later.. In order to facilitate assembling and also to stress the springs initially, blocks s are inserted between the rear stops r and the rear flange k. In a modification, the springs and component parts may be placed the reverse way on the drawrod c, and in a further modification, the casings o, n abut, ,and the sleeve g is placed a short distance from the front end pressure plate d. One or both sets of springs may be of rubber or steel'. but when one is of rubber and one of steel, the springs should preferably be arranged that under heavy blows the rubber springs prevent the steel' spring being pressed home.

Title: Improvements in or relating to emulsion drilling fluids
IPC: C09K8/04
Filed: 1952-06-20
Abstract: The Specification describes the preparation of a sulphonated phenol formaldehyde resin suitable for use in emulsion drilling fluids (see Group XXI), by heating 75 grams phenol with 100 grams concentrated sulphuric acid at 100 DEG C. for half an hour.  53.4 grams of 37 per cent. formaldehyde in 152 c.c. water are then added dropwise at 85 DEG C. over half an hour and the mixture, after addition of 100 c.c. water, heated at 95 DEG  C. for 40 minutes. Small quantities of formaldehyde are then added, with a long period of heating after each addition, until the viscosity reaches 150 c.p. whereupon the reaction is stopped by adding phenol.  The resulting solution is neutralized with 40 per cent. caustic soda. The Specification refers also to the use of phenols containing substituents such as CH3, C2H5 and Cl in the meta position, and to ammonium, calcium, lithium and potassium hydroxides for neutralizing the final product.

Title: Digital positioning system
IPC: B23Q15/22
Filed: 1966-04-07
Abstract: 1,141,853. Programmed control of machine tools. GIDDINGS & LEWIS Iric. April 7, 1966 [April 12, 1965], No.15643/66. Heading G3N. In a programmed digital positioning system for moving one or more elements along co-ordinate axes a record medium having successive blocks of data thereon is sensed a block at a time and digital position values are time sequentially compared in a digital algebraic combining device producing a time sequenced output, or outputs, representative of their run or runs, and means moving the element, or elements, until each output equals a predetermined low value. As shown, a block-of information in a punched tape, comprising desired positions of a saddle 55 and a table 58, is scanned photoelectrically in a tape-reader 91, decoded and distributed to X, Y command stores 92, 94. The block of information may also include selection codes, each of which is held in a store 96 and through a decoder 98 renders effective a dial switch 95 set for a particular correction such as cutter wear. When the block of information is stored, an adder-subtractor, see Specification 1,141,852 under control of multiplex gates 106, sequenced by timing signals, algebraically combines the X, Y command numbers with the correction numbers, stored in switches 95, and the resulting adjusted command numbers X' Y' are transferred to the stores 99, 100. The actual positions of the saddle and table are derived from reversible counters 102, 101 responsive to the increment pulses from generators PGY, PGX driven by lead screws. The adder-subtractor 105, after completion of the correction routine, then repeatedly subtracts the actual position numbers held in stores 101, 102 from the adjusted numbers in stores 99, 100 and the resulting numerical error is compared with switch point values held in stores 111, 112. Above a predetermined error the velocity of the saddle and the table, determined by motors 86, 68 and multi-ratio transmissions TY, TX, is at a maxi - mum. As the error falls to successive preselected switch point values, signals are applied to slowdown networks 114, 115 which change the energized pattern of clutches in the transmissions TX, TY thus reducing the velocities of the table 58 and saddle 55. To bring the saddle and table precisely to the adjusted positions, a fine analogue positioning system is employed, see Specification 1,141,851 which is enabled when the error falls to a value within a span of the analogue system. Information is fed from the final digits of adjusted command stores 99, 100 to BCD-to decimal converters 120, 130 the outputs of which are transferred to digital to analogue converters 121, 131 which energize windings of sliders 124, 134. The detected errors from scales 125, 135 are fed to analogue error detectors 136, 137 controlling the slowdown networks, 114, 115.

Patent GB-566495-A (GB)
Title: Manufacture of esters of 12-ketostearic acid
IPC: C07C69/716
Filed: 1942-11-06
Abstract: Esters of 12-ketostearic acid are prepared from an ester of ricinoleic acid with an alcohol having 1 to 3 carbon atoms by heating in the presence of a catalyst obtained either by reducing a nickel or cobalt salt with sodium naphthalene or by extracting with caustic soda the alkali soluble component of an alloy of nickel or cobalt with an alkali soluble metal.  Ricinoleic compounds other than the above esters may be used as starting materials, the product then being converted into the ester by dissolving it in an alcohol having 1 to 3 carbon atoms, and heating in the presence of an ester interchange catalyst, after filtering off the nickel or cobalt catalyst.  In examples: (1) castor oil is heated with sodium-naphthalene reduced nickel and the product re-esterified with methanol in the presence of sulphuric acid, after filtering off the nickel catalyst; a closed or open vessel may be used and the catalyst may be in the form of pellets; (2) castor oil is similarly treated using a skeleton nickel catalyst prepared by treating a nickel aluminium alloy powder with caustic soda and washing the resulting powder with water and alcohol; (3) methyl ricinoleate is heated with a sodium naphthalene reduced nickel catalyst.  Diluents such as benzene, acetone, cyclohexane and decahydronaphthalene may be used. The use of ricinoleic amide and anhydride and salts of ricinoleic acid is mentioned as starting materials.  The Specification as open to inspection under Sect. 91 comprises also the use of any nickel or cobalt catalyst comminuted at 20-110 DEG  C.  The final esterification step may be omitted.  This subject-matter does not appear in the Specification as accepted.
