Filed: 1921-01-22
Abstract: 176,972. Johnson, Riddle, & Co., Ltd., and Curson, F. B. Jan. 22, 1921. Printing in several colours.-Coloured pictures or designs are obtained by printing the various colours bv means of formes composed of squares or rectangles set up mechanically as by a machine of the single-matrix type-setting kind. A picture &c. is drawn on paper which is ruled to form squares or rectangles, and on similarly ruled paper the squares &c. are coloured in accordance with the squares on the original design which contain the particular colours entirely or as components. From these coloured squares the operator sets a series of square or rectangular types separated by the desired spaces, and the complete picture is obtained by taking superimposed impressions in the various colours from these formes. To obtain shading effects, the rectangular printing-surfaces may be formed with stipples, with one or more thin vertical lines, or with a marginal line with a centre. In some cases the operator can set up the formes direct from the original design. 177,041. Lowther, W. F. March 8, 1921.

Title: A driving mechanism for toys
IPC: A63H31/02
Filed: 1962-01-25
Abstract: 970,427. Toothed gearing. G. A. MARGOLD. Jan. 25, 1962 [July 28, 1961], No. 2923/62. Heading F2Q. [Also in Division A6] A mechanism for toys whereby a drive means is selectively coupled to either of two shafts comprises a displaceable intermediate shaft which in one extreme position of movement causes a gear-wheel secured thereto to engage with a fixed gear-wheel to rotate one shaft and which in the other extreme position is adapted to drive through an axially fixed but freely rotatable gear the second shaft. An electric motor 5 drives, through suitable gearing, a gearwheel 11 on the displaceable shaft 12. In one position of the shaft 12, a pinion 14 thereon drives, through a gear-wheel 31, freely rotatable on the shaft 22, a pinion 32 on the rear axle 33 of a vehicle. In the second position, the pinion 14 drives a gear-wheel 24 fixed to the shaft 22. The shaft 22, through pinion 25 and gear-wheel 27, drives a crank arm 29 on a part 30 of the vehicle. The displacement of the shaft 12 is effected by means of a Bowden cable 19 which rotates an actuating plate 17 engaging slots in side plates 3, 4 against the action of a return spring 18, which holds the shaft in one position, to move a fork-shaped flap 16 engaging the hub of the gear-wheel 11 to cause a spring 15 between the flap and pinion 14 to displace the shaft 12 so that the pinion 14 is displaced from the gearwheel 31 and engages gear-wheel 24 to driveshaft 22. The axle supports a cam which intermittently makes contact with a spot light connection.

Title: Improvements in the manufacture and production of pyridino compounds
IPC: C07D215/16
Filed: 1932-02-01
Abstract: Amines of one-, two-, or three-ringed aromatic compounds which in the case of one-ringed compounds should be free from hydroxy or alkoxy groups attached to the nucleus and in the case of three-ringed isocyclic aromatic compounds do not contain keto groups in p-position to each other, are quinolized by treating with glycerine in the presence of an oxidizing agent in sulphuric acid from about 40-70 per cent strength.  Sulphuric acid of 60-70 per cent strength is particularly suitable, the reaction proceeding without violence to give excellent yields, preferably at reacting temperatures of 100-160 DEG  C.  When glycerine is added gradually to the reaction mixture at practically the same rate as it is consumed by condensation, the strength of sulphuric acid may be increased up to 85 per cent.  The necessary water to dilute the sulphuric acid may be added admixed with the reaction components. Crude glycerin containing water may be employed in the process; suitable oxidizing agents are aromatic nitro compounds, such as nitrobenzene and nitrobenzene sulphonic acids, and arsenic acid; substances assisting oxidation, such as vanadium pentoxide and selenic oxide, may be added.  Suitable amines which may be treated comprise mono-and poly-amino compounds of the benzene series, for example, aniline, toluidine, halogenanilines, nitranilines, halogennitranilines, sulpho- and carboxylic acid derivatives, phenylene diamine and substitution products thereof; naphthylamines, aminofluorenes, aminoanthracenes, aminophenanthrenes, heterocyclic amines, for example, those of pyridine, quinoline, napthoquinoline, acridine naphthostyril, carbazole, diphenyleneoxide, primuline bases.  Instead of the free amines the N-acyl compounds or azomethines or other derivatives yielding the amines under the working conditions may also be used.  In examples, the quinolizing of the following compounds is described: aniline, p-toluidine, o- and p-chloraniline, 2 : 4- and 2 : 5-dichloraniline, 3 : 4 : 5-and 2 : 4 : 5-trichloro-(or tribromo- or triiodo-)-aniline, o-, m- and p-nitraniline, 4-nitro-2-chloraniline, p-amidobenzoic acid, p-amino-acetanilide to (pseudo-phenanthroline), p : p<1>-diaminobenzophenone, p : p<1>-diaminodiphenylmethane, a - and b -naphthylamine, 1-amino-5-nitronaphthalene, 1 : 5-naphthylenediamine, 2-naphthylamine-6-sulphonic acid, 1-naphthylamine - 5 - sulphonic acid, 2 : 8 - aminohydroxynaphthalene-6-sulphonic acid, tetrahydro-2-naphthylamine, 6-aminoquinoline (to pseudo-phenanthroline), aminonaphthostyril (prepared from 1 : 8-aminonaphthoic acid anhydride by nitration and reduction), 3 : 6-diaminoacridine.  The production of metanilic and hydroxymetanilic acid as bye-products is mentioned in some of these examples.  Further examples in the Provisional Specification describe the quinolizing of o- and m-aminophenol.  Reference has been directed by the Comptroller to Specifications 7803/91, [Class 2, Acids and salts, Organic &c.], and 351,605.

Title: Improvements in or relating to the production of margarine and like edible fat emulsions
IPC: A23D7/01
Filed: 1931-01-29
Abstract: For producing improved margarine and like edible fat emulsions there is added thereto a relatively small quantity of one or more compounds having the capacity of preventing spattering of the margarine during frying and a relatively small quantity of one or more "antiweeping" compounds of the type defined in Specification 378,373.  The antispattering compound may be lecithin or nitrogenous lecithin-like extracts or antispattering compounds of the kind defined in Specification 366,909. Antispattering compounds of the kind defined in Specification 366,909 but not specifically referred to in that Specification are: mono sodium stearyl sulphate, palmityl hydrogen sulphate, potassium palmityl sulphate, sulphonated beef tallow, mannitol mono-palmitate, stearyl malic acid, the sodium salt of stearyl diethyleneglycol sulphoacetate, "stearic acid ester of sucrose," carbocholesteroxys methyl quinaldylium bromide, cholesteryl dimethyl aminoacetate hydrobromide, compounds having the formulae:- <FORM:0378372/I/1> and sulphonic acid derivatives of substances possessing lipophile groups, e.g. carboxylic esters of sulpho acetic acid, such as salts of monostearyl sulphoacetate.  The additional substances may be emulsified directly with the principal oleaginous and aqueous ingredients of the margarine in the liquid stage or they may be formed with a liquid substance into a paste which is kneaded into the margarine after the oleaginous and aqueous substances have been formed into an emulsion and the emulsion has been stabilized to form a solid plastic product.  The additional substances may be mixed together prior to the introduction thereof into the emulsion; thus a mixture of the two may be produced by treating one of the antiweeping compounds to increase the hydrophyllic character of the hydrophile group or groups to obtain a mixture of an antiweeping substance with a substance having substantially balanced hydrophile and lipophile groups, e.g. stearic acid may be esterified with glycerol to produce monostearin, an antiweeping substance, and this may then be treated with sulphuric acid to convert a portion thereof to monostearyl sodium sulphate.  Reference has been directed by the Comptroller to Specification 339,558, [Class 1 (i), Chemical processes &c.].

Abstract: 1413621 Backstay tensioner R E KRUEGER 23 Jan 1973 3261/73 Heading B7V A backstay tensioner 20 for adjusting the tension in the backstay 16 of a sailing craft mast includes a housing 22 which contains an hydraulic fluid reservoir 56. A cylinder 38 in the housing receives hydraulic fluid 58 under pressure from the reservoir and piston 44 is movable in the cylinder in response to this hydraulic fluid admitted into the cylinder. Piston-rod 46 extends outwardly at 48 from the housing to connect it to the backstay, the piston and cylinder defining a high pressure chamber 54 arranged such that the hydraulic fluid 58 retracts the piston-rod into the housing. Pumping chamber 62 in the housing receives hydraulic fluid from the reservoir and pump handle 70 and piston 66a delivers the fluid under pressure through line 64, 74, 78 from the reservoir to the high pressure chamber. Second hydraulic line 106 allows hydraulic fluid from chamber 54 to return to the reservoir and normally closed relief valve 96 senses the pressure existing in that chamber. The relief valve is adjustable to open automatically when the pressure sensed by it exceeds a preselected value to channel hydraulic fluid from the high pressure chamber back to the reservoir and allow the piston-rod to extend so that tension in the backstay is limited to a level determined by that preselected pressure value.

Title: Improvements in or relating to electric route-setting equipment for railways
IPC: B61L19/06
Filed: 1952-02-07
Abstract: 713,037. Railway route locking. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 7, 1952 [Feb. 7, 1951], No. 3284/52. Class 105 The electric locking of the points in a set-up route is effected by a route locking relay which is normally held by its magnetic remanence and is released for route locking by a demagnetizing current pulse, the relay being operated again for releasing the route locking by a magnetizing current. To this end the relay is provided with a steel core and one winding for magnetizing said core and another winding for demagnetizing said core. As shown the magnetizing current of the route locking relay TR is made dependent on the contacts X being properly conditioned, on the contact S2 of the signal relay S and on the contact A2 of a releasing relay A (not shown) which is operated when the train leaves the route. Thus with relays S released and relay A operated relay TR receives magnetizing current which is interrupted by contact A2 opening when relay A falls away, but relay TR remains operated on account of the remanent magnetism. To clear the signal a switch at the control switchboard is operated to close contact MS1 and complete the circuit through TR1 for the demagnetizing current impulse by energizing lower winding of relay TR which releases So opening contact TR1 and closing contact TR2 to operate relay S since contact MS2 is closed simultaneously with closing of contact MS1 assuming the other contacts Y are suitably conditioned for the route. Relay S is held over contact S1 and the signal can be cleared. Contact TR3 being now open prevents the panel points levers MM + from operating relays PP+ which control the operation of the points. Thus the points art locked. When the train leaves the route relay A is briefly energized to open contact A1 to release relay S and close contact A2 preparing the magnetizing circuit of relay TR which is completed at contact S2 when relay S drops away.
