Title: Process for the manufacture of soaps of all kinds
IPC: C11D13/02
Filed: 1921-10-01
Abstract: Soaps are made by subjecting fats, oils, fatty-acids or their esters, resins, &c. and alkali, to high speed mechanical disintegration in an apparatus whose moving parts have a peripheral speed of not less than 1000 metres per minute.  The product so obtained is poured into moulds and allowed to ripen, and then worked up into soap blocks. The process may be effected at temperatures less than 100 DEG  C.  If solid fatty acids are used preliminary warming to 60 DEG -90 DEG  C. is necessary.  Fillers such as resins, water glass &c., and colours may be added.  In an example, 100 parts of oleic acid are treated with 55-60 parts of potash liquor of 36 DEG B<\>ae in a colloid mill as described in Specification 155,836 for 1-10 minutes.

Patent GB-444244-A (GB)
Title: Improvements in the manufacture and production of highly viscous oils
IPC: C10G21/14
Filed: 1934-09-13
Abstract: Highly viscous oils obtained by polymerizing or condensing paraffin or other mineral wax, e.g. as described in Specifications 349,071, 407,379, and 410,833, are freed from unchanged raw material and lower molecular products and so improved as lubricants and as agents lowering the setting-point of other lubricants, by extracting (1) with liquid hydrocarbons having a critical temperature below 250 DEG C., the extraction temperature being not higher than 50 DEG  C. above the critical temperature but always greater than 25 DEG  C.; and then (2) with a single or a mixture of different selective solvents mixed or not with other solvents, e.g. liquefied gaseous hydrocarbons. Usually 1--10 vol. of liquefied normally gaseous hydrocarbons are used in the first stage, at 25--35 DEG  C. for ethane and 90--95 DEG C. for propane; in the second stage 1 or more vol. of solvent at 20--50 DEG  C. and preferably at increased pressure.  Solvents specified are phenol, cresol, nitrobenzene, acetone, cyclohexanone, levulinic acid, pyro-racemic acid, aniline, furfurol, liquid sulphur dioxide, and chlorinated ethers.  Retained solvent is removed by washing or by simple or steam distillation.  Example: voltolized ceresine is extracted at 90 DEG  C. with 3 vol. of liquefied propane, and the undissolved oil is freed from solvent, mixed with 1 vol. of illuminating oil, and extracted at atmospheric temperature with 1,5 vol. of tricresol or at 50 DEG  C. with nitrobenzol; the oil layer is separated, and freed from diluent and solvent by distillation. Specification 402,253 also is referred to.
Patent GB-1435378-A (GB)
Title: Apapratus for enabling facsimile apparatus to be used for data print-out
IPC: H04L21/04
Filed: 1973-06-01
Abstract: 1435378 Printers COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 1 June 1973 [1 June 1972] 26351/73 Heading G4H A character generator for a facsimile printer is fed from two circulating buffer memories alternately. In Fig. 2a, telegraphic signals at 1 from a modem are converted at 2 to parallel form with removal of start and stop signals and transcoding if necessary, registered at 2<SP>1</SP>, then gated via 3 or 4, depending on the state of a flip-flop 19, through register 5 or 6 to register 9 or 10 from which they are read-out in serial form into a recirculating loop memory 11, 13 or 12, 14. Read-out is from 9 or 10 depending on the state of flip-flop 19 and occurs when a selection count i (from Fig. 2b, not shown) equals (as detected at 17) the count in an input character counter 7 driven from 2. When counter 7 indicates that a complete line has been received, it reverses flip-flop 19. Thus the loop memories receive one line each, alternately. While one loop is thus being filled, the other is being readout, with serial to parallel conversion at 15 or 16, to a character generator 27, under control of flip-flop 19 when the selection count i equals (as detected at 18) the count in an output counter 8 driven from the last stage of a column counter (see below) associated with the character generator 27. Each character is printed as a matrix of dots, the top row of dots for a whole line being printed, then the second row, and so on, the loop memory being read-out to the character generator repeatedly, once for each row, with the loop circulating once between read-out of successive characters for a given row. As each character is presented to the character generator 27, the generator is scanned by a column counter (41, Fig. 2b, not shown) to read-out the character matrix column by column, the appropriate row bit from each column being selected by a row counter (40) driven by pulses Z produced by a differentiator 25 (Fig. 2a) when flip-flop 19 is switched to its set state or when output counter 8 reaches capacity (last character in line).

Filed: 1937-10-06
Abstract: 503,342. Thermally-actuated valves. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. Oct. 6, 1937, No. 27116. [Class 135] A thermostatically controlled gas valve 6 is actuated by a bellows thermostat 12, 13 exposed to the room temperature. The spring loading 16 on the valve spindle 7 is adjusted by a cam disc 23 acting on pin 22 secured to the bottom of a guide sleeve 17 and rotated by a setting knob 27 to vary the controlled temperature. During normal operation and when the knob 27 is turned to a normal "off" position the valve cannot close completely owing to the movement of the wall 11 of the bellows 12 being limited so that a small byepass of gas is maintained. When desired however the knob 27 can be turned to a full " off " position so that a re-entrant portion 38 of the cam engages the pin 22 and moves the sleeve 17 down against a spring 20 on the valve spindle to close the valve completely. In this latter position a stud 35 on the casing engages a stop in a groove 36 of the knob 27 which has to be pulled out against a spring 28 to reset the device. The cam disc 23 is also formed with a shoulder 39 to limit the maximum valve of the regulated temperature and the byepass position of the valve is adjustable by screwing the whole bellows unit 13 up or down on the value casing.
