Title: Improvements in and relating to solid fuel and processes for the manufacture thereof
IPC: C10L5/40
Filed: 1941-12-01
Abstract: 578,331. Composition fuel. BATHER, J. C. Dec. 1, 1941, No. 15462. [Class 50] A solid aldehyde fuel is formed from a mixture of hexamine with one or more natural or synthetic resins, with or without a small proportion of a lubricant, the whole being compressed into tablets. Some of the hexamine may be replaced by paraformaldehyde or metaldehyde or both, but the hexamine constitutes more than half of the aldehyde content. If metaldehyde is used, a phenol or a phenolic body is used to mask its odour. Examples of resins, of which .2 to 5 per cent. are used, are crude oleo resin from the distillation of turpentine, or natural resins such as copal, pontianec, kauri, or soft manilla resins, or synthetic resins such as a methyl-cyclohexanone-formaldehyde resin. As a lubricant, butyl stearate, oleyl alcohol, triamyl borate, benzyl acetate, ethyl acetate, furfural, ethyl glycol, or esters thereof, of methyl-cyclohexanone, diacetone alcohol, linseed fatty acids, lauric acid, paraffin wax and stearic acid, or rubber latex, and the amount of the lubricant should not exceed 2 per cent. of the total aldehyde. Small amounts of flame colouring substances such as calcium carbonate or boric acid may be added. In an example, 100 parts of hexamine are mixed with 1 part of water and .2 parts of synthetic resin and sprayed with .3 parts of butyl stearate, the whole being mixed and compressed into tablets.

Title: Method of preparing granular zeolitic catalyst or sorbent
IPC: C07C9/00
Filed: 1972-04-04
Abstract: 1383825 Catalyst compositions comprising zeolite INSTITUT ORGANICHESKOI KHIMII IMENI ND ZELINSKOGO AKADEMII NAUK SSSR 4 April 1972 [7 April 1971] 15527/72 Heading B1E [Also in Division Cl] Granular zeolitic catalyst is prepared by a method wherein zeolite, optionally in admixture with binder material, is formed into granules which are treated at elevated temperature, for example of from 150 to 300‹C, and elevated pressure, for example of from 80 to 120 atmospheres, with an aliphatic alcohol, optionally in admixture with water, and thereafter dried, for example at a temperature of from 100 to 120‹C, and calcined, for example at a temperature of from 380 to 550‹C. Zeolite in the sodium form may be treated with an aqueous solution of a salt of a metal selected from Group II and III elements either before formation of the granules or after formation of the granules but before treatment thereof with the alcohol or after treatment of the granules with the alcohol but before drying thereof. The material from which the granules are formed may contain, per 100 parts by weight of zeolite, up to 30 parts by weight of binder material, for example alumina or non- zeolitic aluminosilicate such as clay. Specified aliphatic alcohols are ethanol, isopropanol and butanol; prior to treatment with the alcohol, the granules may be dried, for example at a temperature of from 100 to 120‹C, and calcined, for example at a temperature of from 380 to 550‹C. The granules may be used as catalyst in the catalytic conversion of hydrocarbons. As exemplified, a mixture of 80 weight per cent calcium zeolite Y and 20 weight per cent alumina is moulded into cylinders, dried at 100‹C, calcined at 500‹C, treated at 150‹C and 120 atmospheres with 4 per cent aqueous ethanol solution, dried at 100‹C and calcined at 500‹C (Example 1); a mixture of 90 weight per cent sodium mordenite and 10 weight per cent alumina is moulded into granules, treated at 200‹C and 120 atmospheres with 5 per cent aqueous butanol solution, dried at 100‹C and calcined at 500‹C (Example 2); and a mixture of 84 weight per cent sodium zeolite Y and 16 weight per cent alumina is moulded into granules, dried at 100‹C, calcined at 400‹C, treated at 80‹C with aqueous calcium chloride solution, treated at 200‹C and 80 atmospheres with ethanol, washed with water, treated at 80‹C with aqueous nickel nitrate solution to provide zeolite having a degree of exchange for calcium of 35 per cent and for nickel of 55 per cent, washed with water dried at 100‹C and calcined at 400‹C (Example 3).

Title: Apparatus for converting applied adaptive delta modulated signals to linear delta modulated signals
IPC: H03M7/00
Filed: 1972-05-05
Abstract: 1356209 Delta modulation apparatus WESTERN ELECTRIC CO Inc 5 April 1972 [7 April 1971] 15572/72 Heading G4H Apparatus for converting an adaptive delta modulation bit stream signal to a linear delta modulation bit stream signal comprises a network 14-3 comprising a shift register, comparator and logic circuitry whereby the n most recent bits of the input signal are stored and processed to derive a signal indicative of the step size represented by the presently occurring bit, which is presented to one terminal of a comparator 25, a clock source 23 having a frequency m times that of the bit frequency of the applied signal is activated by the incoming signal to pass pulses to both AND gates 26, 27, the gate 26 being enabled at the start of an applied bit interval to pass clock pulses to the output of the apparatus and to an integrator 28 which produces a staircase waveform which is fed to the other terminal of comparator 25, the process continuing until the two inputs thereof are equal, when gate 26 is disabled and gate 27 enabled to pass the clock pulses to a flip-flop circuit 29 which passes pulses of alternate polarity to the output. The integrator is cleared via circuit 39 at the end of each applied bit interval and a circuit 24 causes a signal indicative of the polarity or logical significance of the presently applied bit to be combined at 32 with the output bit stream to constitute the linear delta modulation signal. Thus a pulse train of one polarity is transmitted for a first interval of each applied bit interval, and a pulse train of alternating polarity is transmitted for the remainder; the duration of the first pulse train is indicative of the adaptive step size to charge an integrator in a L.D.M. decoder to this value and the second pulse train causes the integrator to hunt about this value for the remainder of the A.D.M. bit interval. In a modification, Fig. 4 (not shown), the logic circuits at 14-3 apply a signal to preset a counter which is counted to zero by the clock source to present the first pulse train, and then all pulses are applied to a flipflop as in the above embodiment.

Title: Improvements in or relating to the automatic control of inking rollers
Inventor: MILLEDGE SIDNY ZILLWOOD
IPC: B41F31/12
Filed: 1962-04-25
Abstract: 961,897. Printing apparatus. CROSFIELD ELECTRONICS Ltd. April 11, 1963 [April 25, 1962], No. 15802/62. Heading B6C. [Also in Division F2]  The ductor roller 7 of a press inking system is intermittently rotated by a pawl-andratchet mechanism 8 driven by linkage 9 and 10 from an oscillating member 11. The stroke of the linkage 9, 10, and therefore the stroke of the pawl, is varied through altering the position of member 42 through which the link 10 is connected to the member 11 relative to the axis 41 of oscillation of the member 11. This is effected by incorporating in the member 11 a lead-screw 40 and forming the member 42 as a nut to engage therewith. The position of the nut relative to the oscillator axis 41 may be adjusted by actuation of a handle 23 or, automatically, through the actuation of two solenoids 26 which allow pawls 24, 25 to move intermittently a ratchet wheel 21 fast with the shaft 22 of the lead-screw. These solenoids control balking pins 33, 34 which in the non- operative position of the pawls 24, 25 abut the periphery of arm 30 upon which the pawls are formed. The arm 30 is mounted through a pivot 29 on a chassis 28 forming part of the member 11 and the outer end of the arm is fixed to a part of the press frame through a universal joint and link 32. During oscillation of the member 11 the chassis 28 oscillates about the universal joint and as long as the balking pins 33 and 34 remain against the arm and fixed members 35 and 36 the lead-screw oscillates about the axis 41. On removal of one pin through actuation of the appropriate solenoid deriving from the ink-density control circuit 43 through leads 44 and 45 the arm is allowed to move about the pivot 29, thus causing either the pawl 24 or 25 to actuate the wheel 21 and thus rotate the lead-screw to move the nut 42. The nut may then be intermittently moved to either direction relative to the axis 41, the number of continuous intermittent steps of movement of the nut to either direction depending upon the length of time of operation of the relevant solenoid.
