Title: Improvements in and relating to calculating or accounting machines
IPC: G06C21/04
Filed: 1929-08-09
Abstract: 343,061. Calculating - apparatus. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A.- (Assignees of Muller, R. L.; 14041, Glenwood Avenue, Detroit, Michigan, U.S.A.) Aug. 9, 1929, No. 34315/30. Convention date, Aug. 10, 1928. Divided on 317,090, [Class 106 (i), Calculating &c.]. [Class 106 (i).] In a calculating-machine having means for conditioning the machine for addition or subtraction a mechanism is provided for proving the correctness of the entry of an item in relation to its positive or negative character. As shown applied to the type of machine as described in Specification 317,090, [Class 106 (i), Calculating &c.], in which a proving mechanism checks the numerical value of an item by first setting the proving mechanism and by preventing operation of the machine in a predetermined subsequent operation, unless the same item keys are depressed during the second entry, the subtraction lever 10, Fig. 1, co-operates with arms 172, 174, on a shaft 173 the arm 174 of which controls a lever 176 provided with a lateral lug 178 and a pass-by pawl 179. The lug 178 is adapted to engage a shoulder 181 in a lever 182 having a lower extension 183 engaging a stud 105 on a lever 106 operated by the travelling carriage of the machine in certain columnar positions. If the item in the " pick-up" column has been entered with the lever 10 in the " add " position when the carriage reaches the " proof " column the lever 10 is locked in the " add " position to ensure the second entry is positive. The locking action is effected by a large roller on the carriage rocking the lever 182 sufficiently to cause the shoulder 181 to engage under the lug 178 to block the movement of the lever 176. If the lever 10 had been set originally to the " subtract " position its movement causes the pass-by pawl 179 to move past a pin 187 on an arm carrying the bail 54 described in the above mentioned Specification. The succeeding operation of the machine causes the lever 10 to return to its " add " position a shoulder 188 on the pawl engaging the pin 187 as shown in Fig. 4. When the carriage in this instance moves to the "proof " column the shoulder 188 blocks movement of the bail 54 unless the lever 10 is moved to its subtract position to withdraw the shoulder. After this operation the parts move to normal since the stud 187 moves forward beyond the shoulder 188 so that the pawl and lever 176 are free to return under action of spring 184. Specification 343,060 also is referred to.

Abstract: 212,002. Fowler, J. J. Dec. 16, 1922. Road-traffic signals on vehicles.-Signalling- apparatus for vehicles comprises a pointer &c. which may be swung into various horizontal signalling positions and into a vertical position. The pointer 9 is pivoted to a spring-controlled rod 3 slidably mounted in a container 1 and is operated by a pivoted lever 17, the cam 18 of which is adapted to engage slots in the bottom of the container. The pointer 9 may be swung horizontally into a signalling position by moving the lever 17 into a corresponding slot. The rod 3 has a square end 6 slidably fitting in a cap 5 which is keyed rotatably to the container and has a bayonet fitting 24 for a lamp. When the lever 17 is elevated the cam 18 engages one or other. of the slots in the container 1 and due to its eccentricity draws the rod 3 into the container and so raises the pointer 9. A projection 10 on the pointer prevents it from swinging past the vertical position. The container 1 is carried by a clip 26 having a spring-controlled stem 28 mounted in a holder 29, or it may be held in either a horizontal or vertical position by a pin 35 on the stem engaging slots in the holder. The container 1 may thus be lowered into a horizontal position to permit the passage of the vehicle under low arches. The holder 2@ has slots on each side which engage a keyhole in a bracket 36 mounted on the roof of the vehicle. The holder is locked in the keyhole by a pivoted flap 42.

Title: Method of producing staple fibres
Inventor: MARLEY ROBERT GORDON
IPC: D01G1/04
Filed: 1962-09-10
Abstract: Vinyl chloride copolymer staple fibres, useful in paper-making are made from a tow of vinyl chloride copolymer filaments which is allowed to relax, stretched, and held under tension while being cut into staple lengths.  The tow may be wet- or dry-spun, and if desired may also be stretched before the relaxation step.  The relaxation period may be at least 5 seconds, suitably 5-10 secs, but may also extend to a week or more.  Relaxation may be effected by (a) metering the rate of travel of the tow between pairs of spaced rolls or wheels so that it sags under its own weight, (b) plaiting the tow on an endless belt travelling slower than the rate at which the tow is delivered thereto, or (c) loosely wrapping a series of turns of the tow about a rotating cylinder.  All these methods are suitable for continuous operation.  Extended periods of relaxation e.g. up to a week or more, are achieved by delivering the tow into a container and storing it therein for the desired period prior to cutting.  The degree of stretch applied to the tow may be 5-60% in one or both stretching steps, especially 10-40%.  Specified materials include vinyl chloride-vinyl acetate copolymer, and vinyl chloride-acrylonitrile copolymers.  Fibres so made may be used in spinning yarns or in paper manufacture.  Such fibres have the tendency to curl or entwine with each other and are well open fluffy fibres free of coalesced ends dispersing readily when placed in a liquid medium (e.g. water) and collected on a screen of greater strength, and exhibiting greater and more uniform shrinkage characteristics than conventional vinyl chloride copolymer staple fibres.

Title: Production of hydrocarbons
IPC: C07C1/02
Filed: 1936-12-17
Abstract: In the synthesis of hydrocarbons from methane and carbon monoxide or dioxide under high pressure, a mixture of these reactants which would give rise to an endothermic reaction, (hereafter referred to as the "fundamental reaction"), is modified by replacing a part of the methane by a mixture of hydrogen or water and carbon monoxide and/or carbon dioxide, which will form methane exothermically by a so-called "steering reaction."  The "fundamental reaction" and the "steering reaction" are combined in such ratio that the resulting free energy value of the net reaction, calculated according to the method of Lewis and Randall, does not exceed +5500 gram calories per mol. of the product and may be negative.  The molecular proportion of methane to carbon oxides in the reaction mixture is at least 1/4 .  Pressures above 500 or 1000 atmospheres and temperatures of 450-800 DEG absolute are preferably employed.  In example 1 the fundamental reaction of 17CH4 + 7CO = 3C8H18 + 7H2O, which is strongly endothermic, is combined with the exothermic reaction 15H2 + 5CO = 5CH4 + 5H2O to give a total reaction of 4CH4 + 4CO + 5H2 = C8H18 + 4H2O, wit a free energy value of -849 gm. calories per mol.  A mixture of 38 per cent by volume of H2, 31 per cent CO and 31 per cent CH4 is forced at 1000 cubic metres per hr. through a contact tube filled with iron-molybdenum catalyst at 850 atmospheres and 250 DEG  C.  The product is 315 kg. of hydrocarbons, mainly octane, per hour.  In examples 2-6, using a similar catalyst, (2) cyclohexane is formed from 33,3 per cent H2, 33,3 per cent CO and 33,4 per cent CH4 at 800 atm. and 225-30 DEG  C.; (3) benzene is formed from 33,3 per cent H2, 22,2 per cent CH4 and 44,5 per cent CO at 890 atm. and 370-80 DEG  C.; (4) toluene is formed from 41,7 per cent H2, 16,7 per cent CH4 and 41,6 per cent CO at 1450 atm. and 370-80 DEG  C.; (5) benzene is formed from 22,2 per cent CH4 and 77,8 per cent CO at 1300 atm. and 370-80 DEG  C.; (6) cyclohexane is formed from 16,7 per cent H2, 16,7 per cent CH4 and 66,6 per cent CO at 1270 atm. and 370-80 DEG  C.  In example 7 a mixture of 62 per cent H2, 23,8 per cent CO2 and 14 per cent CH4 is passed at 868 atm. and 250 DEG  C. over a catalyst of vanadium iron to form benzines, mainly octane.

Title: Means for voltage regulation in current converting apparatus
IPC: H02M7/15
Filed: 1934-12-07
Abstract: 434,456. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. Dec. 7, 1934, No. 35204. Convention date, Dec. 7, 1933. [Class 38 (ii)] A voltage-regulating arrangement for a rectifier comprises a device which regulates the grid voltage to enable the D.C. voltage to be controlled to a limited extent, a mechanical voltage regulator for the supply transformer and one or more relays which are operated when the grid control device reaches a limiting position to cause the voltage regulator to vary the transformer voltage a step. In the form shown in Fig. 1, the transformer 1 has a tap changing mechanism 2 adjusted by a motor under the control of relays 8, 9 which respond when contacts 10 or 11 on the grid control apparatus are closed. The grids of the rectifier are controlled by a phase shifting transformer 5 adjusted in accordance with the D.C. voltage by a solenoid which operates in opposition to a spring 7 so that fine regulation of voltage is effected by grid control and coarse regulation by tap changing. The range of voltage regulation for each tap is less than that effected by grid control to prevent hunting. The connection between the phase shifting transformer and the contacts 10, 11 should be somewhat elastic so that rapid changes in load may be corrected by over-regulation of the rectifier. In a modification in which the variable phase grid control voltage is taken from an arrangement of resistance and saturable inductance, the saturating current is taken from a potentiometer across the D.C. circuit in opposition to a source of constant voltage D.C., the coil of a two-way switch controlling the relays 8, 9 being connected in series in this circuit. A rectifier of the dry surface contact type may be connected in this circuit to prevent reversal of current flow. In a modification of this the two-way switch may be replaced by a phase indicator having contacts and connected to the grid voltage. The source of constant voltage D.C. may be from an auxiliary winding on the transformer 1 through a rectifier. The arrangement may be modified to effect compounding or program regulation.

Title: Process for the synthesis of liquid hydrocarbons
IPC: C07C2/00
Filed: 1927-12-30
Abstract: 309,002. Potts, H. E., (Plauson, H.). Dec. 30, 1927. Radiations, treating substances with for effecting chemical reactions.-Liquid hydrocarbons are synthesized by subjecting gaseous carbon compounds; such as are contained in water gas, coke oven gas, natural gas and gases produced by cracking heavy oils, to the action of rapidly moving electrons (#-rays) or the joint action of #-rays and X-rays. The reaction may be assisted by rotating electric and/or electromagmetic field and by catalyst in suspension in the reacting gases. The velocity of the rays should exceed one half the velocity of light and is suitably 200,000 to 260,000 kilometres per sec. The gases after exposure to the rays remain in a reactive condition the effect of which is obtained by circulating the gases under pressure. In addition to hydrocarbons, ketones, alcohols &c. are obtained particularly if the gases contain water vapour. Higher boiling point hydrocarbons may be obtained by subjecting those of lower boiling point to the radiations. According to an example water gas after subjection to radiations is compressed to 800-1000 atmospheres and maintained at this pressure for a time depending on conditions of radiation, temperature and the type of hydrocarbon to be produced. The hydrocarbon produced is mainly of saturated nature. The addition of ethylene, acetylene or other unsaturated hydrocarbons to the water gas shortens the process. The apparatus used may be that described in Specification 299,735. Specification 154,213 also is referred to.
