Title: Improvements in and relating to the production of washing materials particularly for use as shampoos
Filed: 1935-11-04
Abstract: A washing-material adapted for use as a hair shampoo consists of or comprises at least 2 parts by weight of water-soluble alkali fatty soap, and 1 part by weight of a mixture of a lime-soap dispersing-agent and alkali metaphosphate.  The soap may be the usual potassium sodium and ammonium soaps, or soaps of organic bases such as di- or triethanolamines, and may contain sulphonated oils.  The lime-soap dispersing-agent may be a water-soluble salt of an organic acid having the general formula R--SO3--Me, wherein Me is a salt-forming cation and R is an aliphatic, hydroaromatic, or aromatic residue containing at least 10 carbon atoms, and which may be linked to the sulphonic acid residue either directly or through a nitrogen-containing group or an ester linkage.  Suitable dispersing-agents are salts of the aliphatic sulphonic acids, e.g. dodecyl, octadecyl, or octadecylene sulphonic acids, salts of the aliphatic sulphonic acids with nitrogen in the molecule, e.g. dodecylmethylaminoethane sulphonic acid or oleylmethylaminoethane sulphonic acid, salts of the compounds obtained by the condensation of fatty acids and oxyalkyl sulphonated acids or by sulphonating the acids resulting from the breakdown of albumen, and salts of the sulphonated oils or the chlorinated sulphonated oils.  Additional ingredients may be polysaccharides e.g. starch and buckwheat flour, drug extracts e.g. camomile or henna extract, tar, wood tar, pine-needle tar, sulphur, lipoids e.g. cholesterin and lecithin, hormones and vitamins.  An example of a solid shampoo comprises soap, sodium metaphosphate, sodium salt of oleylmethylaminoethane sulphonic acid, borax, sodium salt of lauryl sulphonic acid ester, sodium bicarbonate, buckwheat flour and camomile extract.  The sodium salt of the oleylmethylaminoethane sulphonic acid may be replaced up to one half by the sodium salt of tetrahydronaphthalene sulphonic acid or of naphthalene sulphonic acid.  An example of a liquid shampoo comprises potassium coconut-oil soap, potassium metaphosphate, triethanolaminolauryl sulphonate, potassium salt of dodecylmethylaminosulphonic acid and water.  Reference has been directed by the Comptroller to Specification 439,493.

Title: Improvements relating to a method of and machine for producing briquettes
IPC: B30B11/12
Filed: 1955-10-27
Abstract: 799,190. Briquetting presses. ZWEIGLE, E. Oct. 27, 1955, No. 30825/55. Class 87(2). [Also in Group XXIV] In a method of producing briquettes, material, particularly waste material, to be compressed is fed into a chamber in a preconsolidated condition, is thereafter first compressed in the chamber by pressure exerted radially of an axis of the chamber and then, without the pressing being interrupted, is further or finish compressed to form a briquette by being displaced from the chamber along its axis against a yielding counterpressure. Material to be briquetted falls from a hopper 6, Fig. 1, into a conduit 7 whence rotating vanes 9 press it into a chamber 54, Fig. 3. Dies 14, 15 having semicircular pressing faces then advance towards each other to produce a cylindrical block. Then a piston 27 having a concave pressing face advances to push the block out of chamber 54 into one of four bores 33, Fig. 5, in an intermittently rotated cylinder 28. Within the bores are disposed two double-sided concave-faced sliding dies 29, 30. The block is compressed by the piston against a die 29 to produce a briquette a having two convex ends, the die being pushed to the right against a spring 55. The piston then retracts out of the cylinder, the cylinder turns 90 degrees counterclockwise to present another bore 33 and die 29 to the piston, and the piston advances to push another block into the bore to produce a second briquette b, Fig. 6, the first briquette a remaining in its bore. This sequence is again repeated and a third briquette c, Fig. 7, is made. As the briquette c is made the briquette a is discharged as shown by the sliding movement of the die 29 or 30. The cylinder 28 is mounted in two rocker arms 46 which are urged to the left, Fig. 1, by springs 47 acting through rods 48, and by adjusting nuts 50 on the rods the spring pressure and hence the pressure applied to the material by the piston may be varied. The machine is driven by an electric motor M which reciprocates piston 27 via belt and sprocket gear 2 ...5 and crank 31. The dies 14, 15 are reciprocated via springs 23 by cams 19 on shafts 18 via mitre gears 17 and shaft 4a. The vanes 9 are carried by a shaft 13 rotated by a sprocket drive 10a, 10b, 10c from a shaft 18. The shaft to which the cylinder 28 is secured is rotated intermittently by a ratchet device (see Group XXIV). A stirring device 11 in the hopper is oscillated vertically and horizontally by a crank drive 12 on shaft 13 which carries sprocket 10b.

Abstract: 742,186. Corrugating paper. HALL, C. T., and MOLINS MACHINE CO., Ltd. Nov. 25, 1953 [Dec. 5, 1952], No. 30944/52. Class 141. [Also in Group VIII] Paper 1 to be corrugated, e.g. at 20 per cent moisture content, passes about driven feed rollers 2, 3, the latter, for wide webs, being a series of short coaxial rollers, over a guide roll 4 under a jockey roll 5, over guide rollers 6 and 7 and between rollers 8, 9 about three teeth of each of which mesh with about three of the other, and which may be heated, these rollers being for corrugating only, and not for feeding the web. The jockey roll 5 runs in self-aligning ball races carried on levers 12 so pivoted, at 31, that the roller can tilt to either side should the web be slacker at one side than at the other. The corrugating roller 8 is mounted on pivoted arms 13, so arranged that slackening or tightening of the whole web, and consequent lowering or raising of the jockey roll 5 moves the roller 8 towards or away from the roller 9 so that slightly deeper or shallower corrugations are formed in the web 1. The web 1 passes to a roller 20 and to another 23, where adhesive is applied for a facing ply, the other surface being also faced, subsequently. Specification 729,750, [Group XXXIV], is referred to.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1925-12-09
Abstract: 244,472. Siemens & Halske Akt.-Ges. Dec. 11, 1924, [Convention date]. Automatic exchange systems. - In a switch having groups of terminals in a single row, each directive impulse causes the wipers to move step-bystep over a group under the control of local circuits completed over an extra wiper. Impulses are received over the a wire, and the removal of battery from the b wire at the end of the impulse train permits the wipers to hunt over the selected group. A second selector is described having access to groups each comprising two lines in Fig. 1 and four lines in Fig. 2, but the latter arrangement is also suitable for groups containing any number of lines, and the number in the various groups may be different. When the selector (Fig. 1) is taken into use, relay T energizes over the test wire, and when battery is applied to the b wire, relay B energizes, connecting up relay C, closing a holding circuit for relay T through relay E and opening the energizing circuit of test relay P. Relay E locks over the test wire, and connects up impulse relay A, which responds to the first incoming impulse, and connects up stepping relay U (I) over front contact 9 and wiper d, so thatmagnet D advances the wipers one step. Relay U (I) falls back, and is again connected up on the termination of the impulse over back contact 14 and wiper d, so that the wipers are advanced a further step to the terminals of the first line of the group G<1>. This action is repeated for each impulse, and when the desired group is reached, relay B falls back, completes the test circuit, and releases relav T. If the first line of the group is busy, relay U (I) is again connected up, and the wipers are advanced to the second line of the group. If this line is also busy, relay U (I) remains operated, and when slow-release relay C relapses, busy relay S energizes, connects busy tone to the calling line, and disconnects relay U (I). Upon release of the first group selector, relay E falls back and connects up stepping relay U (II), which interacts with magnet D to restore the selector. When one of the lines of the group is idle, test relay P operates, shortcircuits its high-resistance winding in the usual way, locks relay C, releases relay U (I) and connects up relay W to provide an impulse repeating circuit for the succeeding switch over the a wire. In the case of a group of four lines (Fig. 2), for movement of the wipers to the terminals of the first and fourth lines, the circuit of relay U<1> (I) is closed over front and back contacts 35, 40 of relay A<1>, while for the intermediate steps it includes an interrupting contact 39 of magnet D'. The initial hunting circuit for relay U' (I) is closed upon release of relay T' as before.
Patent GB-813410-A (GB)
Title: Manufacture of lactams
Inventor: DUXBURY FREDERICK KEITH
Filed: 1956-10-12
Abstract: Lactams are prepared from amino-esters having the formula NH2.R1.COOR2 wherein R1 is a polymethylene radical containing 3-6 carbon atoms, which may optionally bear methyl substituents, and R2 is an alkyl or cycloalkyl radical, by heating the amino-ester in the vapour phase at 250-300 DEG  C. for a time insufficient for substantial polymer formation.  The reaction is preferably effected in the presence of a dehydration catalyst and/or water vapour, generally at atmospheric pressure.  The water vapour may be present in amounts of up to 70 per cent by weight of the amino ester.  The vaporized ester may be diluted with an inert gas.  In examples, isopropyl o -amino caproate or aqueous solutions of that ester or of sec.-butyl o -amino caproate are vaporized and the vapours are passed over activated alumina or Raschig rings heated to between 250 DEG and 275 DEG  C. with contact times ranging from 2-7 secs., yielding caprol lactam, which is isolated by condensing the gases and fractionating the condensate.  Reference is made to the use of the methyl, ethyl, isopropyl and cyclohexyl esters of o -amino-butyric, -valeric, -caproic and enanthic acids as starting materials and, as another catalyst, silica gel.  Amino esters for use as starting materials may be prepared as described in Specification 810,332.

Title: Electric toasters
IPC: H03K17/292
Filed: 1973-06-29
Abstract: 1452332 Toasters BEST PRODUCTS Ltd 27 June 1974 [29 June 1973] 31177/73 Heading A4D An electric toaster has electromagnetic means electrically energized to counteract operation of toast displacement means, the electromagnetic means being de-energized when the slice or slices are toasted to the desired degree to permit the toast displacement means to move the toast away from a heating means. When a toast support 34 is pushed down it closes switch S supplying electricity to elements 20, 22, 24 and winding M of electromagnet 64. Plate 62 is held against pole tips 68, (70) of core 66. Toasting time is varied by knob 80 which varies resistance R6, a thermistor TH1 compensating for the effect of change of temperature on the control circuit 77. When capacitor C2 is charged, thyristor SCR1 receives a pulse from uni-junction transistor Ul and conducts to short out winding M and de-energize electromagnet 64. Support 34 is released and moved upwards by springs 52, 54 to strike a bell 60 and release switch S to de-energize the elements. Various forms of electromagnets and contacting plates are described Figs. 10, 11 (not shown) including two windings in series Fig. 12 (not shown) and in Figs. 15, 16 (not shown) coating an arm (84) of the core 66 with insulating material (86) to reduce the arm's magnetic permeability and extinguish the magnetic field between plate 62 and pole tip (70) very rapidly when the winding is de-energized to rapidly release support 34. In Fig. 17 (not shown) an air-gap is provided for the same effect between plate 62 and pole tip (70) and in Fig. 18 (not shown) the air-gap is variable by a movable strip (88). In Figs. 13 and 14 (not shown), when support 34 is moved down, core 66 attracts a latch member (96) or (108) to engage bar (94) or foot (106) on support 34 to hold the support down. Printed circuits or an integrated circuit Figs. 5, 6 (not shown) may be used. In Figs. 7, 19, 20 (not shown) light from an electric lamp (116) is directed on to the bread and the reflected light is led to a photo-resistor (114) whose resistance increases as the amount of light incident thereon decreases with the browning of the bread, the photo-resistance and variable resistance R6 forming a potential divider network operating transistor Ul when the toast is ready as pre-set on resistance R6. Alternatively Fig. 8, (not shown) signals from photo-resistor (114) and resistance R6 may be compared by a differential amplifier (122) whose output fires thyristor SCR1. In Fig. 21 (not shown) a toasting compartment (140) is fixed on a pivotable arm (142) which is held during toasting by core 66 after the bread has pushed lever (146) to operate switch S. In Fig. 22 (not shown) a pivotable cover (162) is closed to move toast support (34a) against the action of spring 165 downwards, the cover then pressing on switch S and contacting the electromagnet's core.
