Abstract: 465,316. Addressing - machines. ELLIOTT, H. P. May 11, 1936, No. 13356. Convention date, March 20. [Class 100 (ii)] An address is printed on a record sheet and data associated with the address is recorded on the same sheet by means of a printing- plate provided with address-printing characters and with means, such as perforations, the positions of which determine the data they represent. Each one of a series of stencil-cards 16, Fig. 8, carries a stencil 72, and a part 74 divided by printed lines into rectangles each of which is numbered and may have a printed circle 78 showing where the perforation can be punched. Each rectangle represents an item of statistical information, relating to the addressee according to a code, the address and information being printed on a sheet bearing a printed form corresponding to that on the stencil. The code may be printed on the stencil or on a separate sheet. The stencils are passed through an addressing-machine in which perforating-pins are carried by a plate 96, Fig. 5, spaced above a stationary guide-plate 88 and pressed upwardly against stops by springs 100. Pins 108 are placed in selected coinciding apertures in the plates 88, 96 and are depressed for punching by a soft rubber pad 114 secured to arms carrying an inked impression roller.

Title: Apparatus for cooking in heated liquor
IPC: A21B5/08
Filed: 1927-05-18
Abstract: 278,621. Bergner, J. C. May 18, 1927. Apparatus for cooking in fat and oil.-Articles are cooked in liquor which is whirled in a gyratory course to convey the articles through the apparatus. The apparatus shown comprises a receptacle 1 for the liquor, which is heated by a burner 61 and whirled by a submerged paddle 6 mounted on a shaft 7 driven by a motor 9. The articles to be cooked, for example doughnuts, are dropped into the liquor through a central aperture 5 in the cover 3 of the apparatus, and are carried by the movement of the liquor around a spiral path formed by a foraminous spiral guide 12 carried by a spider 13 removably supported on lugs 15. At a point about midway of their path, the doughnuts are successively inverted by a device comprising a number of radial supporting surfaces 19, Fig. 5, which is intermittently turned, through the medium of shafts 20, 29, and 28, by a geneva mechanism 23, 24 carried on a bracket 21 and driven by a gear wheel 26 on the shaft 7. At the end of their path, the doughnuts enter an offset or trap 35 and are carried up out of the liquor by an elevator 36 intermittently operated through a vertical sliding rod 41, link 43, and lever 44 by a crown cam 47 on the shaft 7. A depending guard 38 carried by the elevator prevents doughnuts entering the trap 35 when the elevator is raised. The cam 47 causes a dwell of the elevator in the lower and upper -positions, and during the latter period the doughnuts are swept off it into a basket 50 by a curved arm 48 carried by a pivoted shaft 49 actuated, through an arm 52 secured to it, a rod 53, and a bell-crank lever 54, 57, by a cam 59 on the shaft 7.

Patent GB-632822-A (GB)
Title: Process for the production of substituted thiophanes
Filed: 1947-05-21
Abstract: Substituted thiophanes are obtained from 1-nitro-2-halogen-2-alkyl-ethanes, where the alkyl group carries a hydroxyl, alkoxyl, halogen, formyl, carboxyl, carbalkoxyl, carbamido or cyano substituent, by condensation with mercapto-acetal and alkali to substituted diethyl sulphides; the acetal group is hydrolysed to the aldehyde group with an acid and the product ring closed with ammonia to a 2-substituted - 3 - nitro - 4 - amino - thiophane; the nitro group is finally reduced to an amino group.  Reduction may be effected with aluminium amalgam and ether, or with iron or zinc with hydrochloric or acetic acid.  The example shows the product with o -carbethoxybutyl as the 2-substituent.  The starting material is obtained from an adipic acid semi-ester chloride (e.g. the ethyl ester) which is converted into a -formyl-valeric acid ethyl ester by treatment with hydrogen in xylene in the presence of a palladium-barium sulphate catalyst.  The aldehyde-ester is treated with nitromethane to yield 6-hydroxy-7-nitro-1-heptanic acid ethyl ester and the product treated with phosphorus pentachloride to give 6-chloro-7-nitro-1-heptanic acid ethyl ester.  This is now converted by the process of the invention into 2-(o -carbethoxy-butyl)-3 : 4-di-amino-thiophane, from which biotin may be obtained by the action of phosgene in alkaline solution.  According to the Specification as open to inspection under Sect. 91, 2-substituted-3 : 4-diamino-thiophanes can be obtained from 2-substituted 3 - nitro - 4 - hydroxy - thiophanes by esterification of the hydroxy group and treatment with ammonia to give 3-nitro-4-amino-compounds via the 3-nitro-3 : 4-unsaturated compounds.  The nitro group is then reduced.  An example is given of the acetylation of 2 - methyl - 3 - nitro - 4 - hydroxythiophane, treatment with ammonia, and reduction with iron and acetic acid (or hydrochloric acid) to yield a mixture of stereoisomeric 2 - methyl - 3 : 4 - diamino - thiophanes from which a dihydrochloride, diacetate, dibenzoate and dipicrate can be obtained.  The diamine can be ring closed with phosgene and alkali to give 2-methyl-3 : 4-(21-ketotetrahydroimidazolo)-thiophane.  The production of mercapto-acetal from bromoacetal and potassium hydrosulphide is also mentioned.  This subject-matter does not appear in the Specification as accepted.

As shown in Figs. 1 and 2, contacts P, R upon the plug engage with contacts c<3>, b<5> in the box, the contact b<5> being carried by the spring-controlled switch arm B which is operated by the plug to close the circuit at the contact b<1>. The contacts c<1> are secured bv screws c<3> to a part c<5> on a base C and extend through openings c<7> in a sleeve c<4> into engagement with the plug contact P. The plug is retained in its two positions by the engagement of a pin h<4> with either notch g<2> or notch g<3> in slot g<1>, or the plug may be completely removed and the socket closed by a cap g<4>. In a modification, the parts R, b<5> are not conductors, but the plug is provided with a second contact similar to the contact P to engage with fixed spring contacts in the box. The slot g<1> may be of cam or helical form, and may be provided on the plug to engage with a pin on the socket.
