Title: Improvements in or relating to record-card-controlled statistical machines
Filed: 1926-12-31
Abstract: 288,360. Campbell, C., and British Tabulating Machine Co., Ltd. Dec. 31, 1926. Statistical machines. - A statistical machine for Hollerith-type cards wherein the hole positions are read successively in sequence, has an intermediate impulse-charging device receiving an impulse from each card when the latter is read and emitting an operating impulse one card cycle later, at the corresponding moment in another sequence, which differs from the first sequence in that the length of the time intervals of the impulses is shortened. The cards pass the brushes in the order 9, 8, 7 - - 1, 0, 10, 11, the "10" and " 11 " positions following the " 0 position. A magnet 10, Fig. 1, in the reading-brush circuit, when operated by a hole in the card, attracts its armature 14, releasing a trip-lever 16 which opens normally closed contacts 24 in the reading-brush circuit, whereby the magnet is only energized momentarily. An insulating disc 26, rotating once in two cardcycles, carries two plates 28, each of which carries twelve spring-closed switches 30; each switch, Fig. 2, is held normally open by a plunger 32 having a groove 34 engaged by one end of a trip pawl 36, the other ends of these trip pawls passing the end of the trip lever 16 in synchronism with the passage of the hole-position on the card past the reading brush so that when a hole energizes magnet 10 the lever 16 rises and trips the appropriate pawl 36 out of its groove 34, closing the correct contacts 30. Almost immediately the trip pawl wipes past the end of the lever 16, depressing the latter into its latched position. After nearly two card cycles the pawl is relatched in the groove 34 by a fixed cam 52 engaging the plunger 32. For the switches 30 the blades 31 are all connected electrically to the plate 28 but the insulated fixed contacts 33 are connected to twelve segments 40, on the same side of the disc 26, but in the revised order 11, 10, 9, 8 - - 1, 0. Also the twelve segments 40 occupy an arc equal to <10>/12ths of the arc of the twelve switches 30. These segments are read a card-cycle later by a brush 44 connected to a Hollerith counter adapted for duodecimal working, but operating only during the normal decimal time period. Thus a machine normally timed to work on the decimal system is adapted to work duodecimally with appropriate counters.

Title: Structure and method of operation of open hearth and other regenerative furnaces
IPC: C03B5/237
Filed: 1922-12-07
Abstract: 190,165. Kernohan, R. B., Lochhead, J. S., and Trinks, W. Dec. 8, 1921, [Convention date]. Liquid, gaseous, and pulverulent fuel furnaces. -In open-hearth furnaces using gaseous or liquid fuel, a short sharp flame of high velocity is produced in the furnace in the vicinity of the fuel and air ports by inducing one of the gaseous constituents of a combustible mixture and effecting its mixture with one or more other constituents by fluid jets of high velocity consisting of air, oxygen, steam or inert gases. Fig. 2 shows the application to a reversible regenerative openhearth furnace. Gas is supplied through passages 3, 6 and downwardly inclined ports 4, and air through passages 2, 7, 8 and downwardly-inclined ports 5 in the usual way. In carrying out the invention, jets of fluid of high velocity supplied by nozzles 19, preferably of the form shown in Fig. 6, induce a flow of air from the vertical ducts 7, 8 through downwardly-inclined converging passages 9, 10 leading into the central gas port 4. By regulating the valve 23 in the pipe 21 supplying the nozzles 19, the proportions of the air supplied to the port 4 and to the port 5 may be varied to vary the nature of the flame. Fig. 3 shows a modified form of furnace in which various fuels may be used. Liquid fuel such as oil or heated tar is supplied by a pipe 25 and gaseous fuel by pipes 26, 27 into the port 104 where it is met by air induced by jets of high velocity from nozzles 119, 120 to pass from the air ducts 7, 8 to ducts 109, 110 leading into the port 104. The flame from the port 104 is supplied with additional air from a port above. According to a further modification, the nozzles 119, 120, shown in Fig. 3, may be arranged at the entrance to the ducts 109, 110, and at the outlet ends of the furnace the flow of fluid from these nozzles may be maintained so as to partly or wholly prevent the escape of gases from the fuel port and cause them to escape through the air port. The Specification as open to inspection under Sect. 91 (3) (a) describes a regenerative ingotheating furnace, Fig. 6 (Cancelled), in which gaseous fuel is supplied through a pipe 31 and also through a pipe 327 which delivers into a by-pass 32 through which air from the regenerator 30 is caused to pass by compressed air delivered through the pipe 319. In a mcclification of this form of furnace, both the air and gas are regeneratively heated. A billet-heating furnace, Fig. 7 (Cancelled), is also described in which compressed air is delivered by a pipe 419 into the airuptake passage 407 leading from a regenerator or recuperator. Fuel is supplied by a pipe 427 into the chamber 404. The use of pulverized fuel is also referred to. This subject-matter does not appear in the Specification as accepted.
Patent GB-872846-A (GB)
Title: Process for naphthalene thioglycollic acids
Filed: 1957-10-28
Abstract: Naphthyl thioglycollic acids such as <FORM:0872846/IV (b)/1> and <FORM:0872846/IV (b)/2> are prepared by heating a naphthol or a lower ether of a naphthol with (1) thioglycollic acid or one of its esters, or (2) a salt of an S-ester of thiosulphuric acid of the formula MO-SO2-S-CH2-X (wherein M is a metal-ion and X is a carboxyl, carboxylic ester, carboxylic-amide or nitrile group), in the presence of an acid catalyst such as sodium bisulphate, p-toluene sulphonic acid, or an alkane sulphonic acid.  In the case of the esters, amides and nitriles, the diluted reaction product is hydrolysed to the free carboxylic acid.  In Example 1, thioglycollic acid and 1-naphthol are heated at 115 DEG C. in the presence of sodium bisulphate, under a nitrogen blanket, to give 1-naphthylthioglycollec acid.  Example 2 relates to the preparation of 2-naphthylthioglycollic acid by heating 2-naphthol and thioglycollic acid in the presence of mixed alkane sulphonic acids.  Example 3 relates to the preparation of naphthalene-1,5-bis-thioglycollic acid by heating 1,5-naphthalenediol with thioglycollic acid in the presence of p-toluene sulphonic acid. The same reaction may also be used to prepare 1 - naphthol - 5 - thioglycollic acid.  Example 4 relates to the preparation of 2-naphthylthioglycollic acid by heating 2-methoxynaphthalene and thioglycollic acid in the presence of p-toluene sulphonic acid.  In Example 5, ethyl thioglycollate is heated with 2-naphthol in the presence of mixed toluene sulphonic acids.  The reaction mixture is then diluted with water; the insoluble product is isolated, re-slurried with water, made alkaline with caustic, and heated on a steam-bath until saponification is complete.  The mixture is finally acidified to give 2-naphthylthioglycollic acid.  In Example 6, sodium carboxymethyl thiosulphate and 2-naphthol are heated in the presence of p-toluene sulphonic acid; and the reaction-product is hydrolysed to yield 2-naphthylthioglycollic acid.  Sodium carboxymethyl thiosulphate is prepared by reacting chloroacetic acid with sodium thiosulphate.  Example 7 describes the preparation of crude sodium S-carbethoxymethyl thiosulphate, and its subsequent use in the preparation of 2-naphthylthioglycollic acid.  Examples 8, 9 and 10 relate to the preparation of 2-naphthylthioglycollic acid from 2-naphthol and sodium S-carboxamidomethyl thiosulphate, sodium S-cyanomethyl thiosulphate, and sodium carboxdimethylamido-methyl thiosulphate, respectively.  The Specification also makes mention of the following naphthalene starting materials:-5-carboxy-2-naphthol; 7-sulpho - 2 - naphthol; and 3 - methyl - 2 - naphthol. Intermediates may be prepared by the action of chloroacetonilide and chloroacetmorpholide on sodium thiosulphate.
