Filed: 1920-12-10
Abstract: 176,161. Shorter, A. N. Dec. 10, 1920. No Patent granted (Sealing fee not paid). Stands or supports for vehicles.- An adjustable strut hinged to the axle and used as a tilting jack to raise the vehicle is combined with an adjustable wedge up which the wheel may run. The strut 1 is pivoted at one end to a clip 4 on the axle of the vehicle and into the other end is screwed the shank of the base. To assist in the lifting action of the strut the wheel runs up a wedge in which the inclined member 11 is hinged at one end to the base 10, whilst the other end is supported by a strut 12 which may be varied in height by inserting it in different slots in the base.

Title: Improvements relating to the refining of paraffin wax
IPC: C10G73/36
Filed: 1937-12-16
Abstract: 507,761. Refining paraffin wax. BURMAH OIL CO., Ltd., and HARLEY, C. R. S. Dec. 16, 1937, No. 34912. [Class 91] Paraflin wax is refined by impregnating a carrier of absorbent and reinforcing material to form a solid film, heating the impregnated carrier, and subjecting it to momentary pressure so as to release and remove the sweats. The carrier may be an endless band of cotton duck or a similar wool fabric and may be heated and pressed at successively higher temperatures; in examples, the temperature is increased in small stages from 110‹ or 130‹ to 180‹ F., and sweats removed at each stage. As described, a dry endless band a is immersed in molten wax in a jacketed tank c, excess wax may be removed as the band moves out of the tank by two adjustable doctor blades (not shown), and the band may be cooled in air or passed through cold water in tank d to solidify the wax. When a sufficient length of the band has been impregnated with solid wax the band is passed comtinously through tanks c, d and between sets of rolls b, b immersed in water or other liquid in sweating tanks e. The water is kept at successively higher temperatures in successive tanks by electric heating with thermostatic control. The band is brought up to the necessary temperature in tanks e before reaching the rolls. Each pair of rolls is enclosed in an open casing h, so that the sweats may be,skimmed off and collected separately as they rise to the surface of the water. In a modification. Fig. 3 (not shown), the band moves horizontally through the sweating tanks. The pressure on the band may be adjusted by tensioning a spring which raises the lower roll. A smooth temperature gradient may be maintained in the sweating tanks by thermostatic control. Removal of the sweats may be aided by circulating the water in tanks e or by adding surface-tension reducers e.g., soaps, there may be more than two rolls in a set, and the rolls may be ribbed. The band is dried after leaving the last sweating tank.
Patent GB-373239-A (GB)
Title: Improvements in or relating to cracking oils
Filed: 1930-11-21
Abstract: <PICT:0373239/III/1> Oils are cracked by heating them to cracking temperatures while flowing through a heating coil, passing the products directly into a coking chamber and leading the vapours evolved into contact with a spray of the crude oil in a separating chamber, from which the liquid is removed while the vapours are conducted to a fractionating tower where they are fractionated into a light fraction constituting the anti-knock spirit required and a condensate which is used as the cracking material.  The heavy oils removed from the separating chamber are coked in the coking zone by contact with hot vapours from the cracking zone.  Oil is vaporized and cracked by passage through coils 11, 12, 13 arranged in a furnace 10, the coils 11, 12 preferably being arranged horizontally and the coil 13 vertically.  The coil 11 is heated mainly by convection heat while the coils 12, 13 are heated by radiant heat from a central downwardly extending burner.  The oil is passed through the coil at high velocity e.g. 20-50 ft. per sec. with a drop of pressure of 200-400 lbs.  The cracked products are introduced at 950-1200 DEG  F. into coking drums 14 where the heavy residues are reduced to coke while the vapours pass to a separating chamber 15 where they are cooled to about 600-900 DEG  F. by contact with the crude stock fed through a pipe 27 and by condensate introduced from the base of a tower 16 by a pump 22. Uncondensed vapours pass to the fractionating tower 16 and a heavy residue is removed through a pipe 54.  From the tower 16 the desired fraction having preferably an end point below 450 DEG  F. is removed and passed through a condenser 17 to collection tanks 18. Condensate formed in the tower is removed by a pump 19 to a storage tank 20 and is used as cracking stock by passing it through a pipe 21 to the furnace 10.  The fractionation in the tower 16 may be controlled by introducing part of the end product from one of the tanks 18 by a pump 561.  Crude oil is introduced into the system through a line 26 and is preferably preheated in a heat exchanger 24 by heat exchange with the hot residues from the separator, before introduction into the separator through the line 27 and valved pipes 28.  Alternatively the crude oil may be further heated in the coil 11 before introduction into the separator by directing it through a pipe 29, the coil 11, and a pipe 30, in which case the condensate from the tower 16 is sent direct to the coil 12 through a valve 34.  The condensate may be preheated by exchange of heat with the hot residues in an exchanger 23. by circulation through lines 210, 211.  Residual oil from the separator 15 may be withdrawn from the system as fuel oil in which case an extraneous oil is introduced into the chambers 14 and coked there, or may be itself coked in the chamber 14 by passing it through lines 37, 38, 42 and valved pipes 43.

As described the apparatus shown in Fig. 1 of Specification 758,508, which is referred to, wherein a decimal digit is stored by forming a conductive path between a selected one out of ten electrodes and a container of tricresyl phosphate and iron filings, into which the electrodes dip, is used to store decimal digits on a two-out - of five code. In the drawing, three groups of five electrodes 42, weighted 1, 2, 4, 7 and C respectively, are shown dipping into a container 12 (the digit zero being coded as 4 and 7). Each group, for example the extreme right-hand group, has associated with it two relays R10 and R28, the first of which when energized connects the electrodes to a ten-key keyboard (each key being shown twice) allowing data entry in a similar manner to that described in Specification 758,508, and the second of which when energized connects the electrodes to a coding emitter E1 for the read-out of stored data in a form suitable to control record card punch magnets. Consider for example the readout of a 6. As brush 127 of emitter E1 rotates anti-clockwise it successively applies a voltage to various electrodes but it is not until it reaches contact 6 that a voltage is applied to brush 126, the current passing from brush 127 and contact 6 via electrode 4, the container and electrode 2 to contact 6 and brush 126, from where a voltage is applied to a brush 128 and its contact 6 to fire a thyratron T6 for energizing a punch magnet. In this manner digits are read successively from successive groups of electrodes and punch into successive card index position, during each of which the emitter El will make several revolutions.
