A magnetic transducing device comprises an electron gun 11 having an external magnetic core 30 whose pole-pieces 31, 32 form a non- magnetic gap 33 co-operating with a magnetic record medium 34, the signals from which produce magnetic variations in the core which interact with the electron stream whereby a varying electric potential is obtained between electrodes 21, 22. An isolating tube 10 of magnetic material for screening the transducer from external fields may be provided and this may be filled with damping material 45 to prevent microphonic effects. In the absence of a magnetic potential at the polepieces 31, 32 the electron stream is evenly distributed between the electrodes 21, 22, but with the application of a field to the polepieces 31, 32 the electron beam is directed to one or other electrode to produce an electric potential between them. In an alternative construction the envelope 135, Fig. 15, containing the electron gun is reduced at 136, and this part is surrounded by pole-pieces 153, 154 defining a non-magnetic gap 160. Modifications of this embodiment are described and output circuits are shown.

Title: Improvements relating to the manufacture of helically grooved roller covers, sleeves, tubing and the like
IPC: B29D23/18
Filed: 1949-03-01
Abstract: 662,168. Moulding rubber &c. tubes, roller covers &c. NORTH BRITISH RUBBER CO., Ltd., and McGOWAN, R. Jan. 3, 1950 [March 1, 1949], No. 5611/49. Drawings to Specification. Class 87(ii) A process of manufacturing helically grooved sleeves, roller covers or tubing from an extruded or otherwise formed tube of rubber or like vulcanizable material comprises inserting the tube in a helically wound wire former having the diameter and gauge which will give the desired helical grooving, expanding the tube against the former by the application of internal fluid pressure to the tube, heating the expanded tube so that it is vulcanized and the helical grooving of the former is permanently impressed thereon, and removing the former from the tube after the latter has been cooled or allowed to cool. An inflation compound, e.g. ammonium carbonate, may be inserted in the tube and the ends thereof sealed by plugs, e.g. of unvulcanized rubber, held by adhesive tape. The heat of vulcanization causes the compound to decompose into gas and provide the fluid pressure. The plugs become bonded to the ends of the tube and enable it to be withdrawn from the coil by pulling one of the sealed ends, which are afterwards cut off.

Abstract: 755,751. Bottle washing machines. SEITZWERKE GES. Feb. 26, 1954 [Feb. 28, 1953], No. 5643/54. Class 138(1) In a bottle washing machine of the type comprising a plurality of bottle baskets 13, Fig. 1, movable intermittently through the machine by means of an intermittently acting driving wheel 11 and spray pipes 24 insertable into the bottles 31, Fig. 2, when the baskets are stationary, each basket 13 has end rollers 29 adapted to run on guide rails 30 and is separately removable from the rails at the front end of the machine by guide wheels 12, Fig. 1, driven from the wheel 11 which is simultaneously adapted to operate the movements of the spray pipes 24, by means of a linkage system 16, 17, 18, into and out of the bottles 31 in the baskets 13 positioned above the spray pipes. The gear wheel 11 also drives a pinion 14 carrying an eccentric pin 15 connected by a rod 16, bell crank 17 and a rod 18 with a slide 19 mounted on a fixed rod 28. The slide 19 has a bracket 22 carrying a support 23 for the spray pipes 24 slidable in fixed guides 25. During a period of rest of a basket 13 on the rails 30, the gear 11 rotates to cause the pipes 24 to be moved into and out of the bottle in two adjacent baskets 13. Whilst inserted in the bottles the pipes 24 are supplied with liquid from the support 23 by a pipe 26. The baskets are secured in their stationary positions by a centering comb 21 (the actuating mechanism of which is not shown) which is lowered to engage basket rollers 20. The connecting rod 18 comprises two parts resiliently connected together by a compression spring 35. The spring is disposed between a collar 34 on the upper end of a rod part 33 and a flange on the lower portion of a housing 32 secured to the other part of the connecting rod. A lug 37 on the rod part 33 normally engages a, switch 36 carried by the housing 32 to close the electric circuit of the driving mechanism of the machine. If the spray pipes encounter an obstruction such as a closed bottle, the two parts of rod 18 move relatively to one another against the compression of the spring 35 and the lug 37 is disengaged from the switch 36 which opens to stop the machine.

Title: Improvements in or relating to the production from paper or cardboard of tubes having a polygonal cross-section
IPC: B31C11/02
Filed: 1957-02-19
Abstract: 813,873. Moulding resin-impregnated cardboard &c. tubes. ETABLISSEMENTS J. J. CARNAUD & FORGES DE BASSEINDRE. Feb. 19, 1957 [Dec. 21, 1956], No. 5658/57. Class 87(2). A paper or cardboard tube of polygonal crosssection is produced by axially moving a rotating helically wound tube from a mandrel of circular cross-section, on which it is formed in known manner, over a freely rotatable mandrel of polygonal cross-section so that the cross-section of the tube is changed from circular to polygonal. A tube of square cross-section is produced by the apparatus illustrated in which the tube is initially formed by winding gummed paper on a round mandrel 1 and is rotatably and axially moved onto a mandrel of generally square crosssection having three parts ; a chamfered first part 12; a second part 18 of cross-section greater than part 12 and perimeter equivalent to that of mandrel 1, and a third part formed of four rods 22 rigidly coupled to part 18 ; the parts 18, 22 being rotatable independently of part 12. As the tube passes onto the part 18 it rotates it and the faces of the tube are flattened by the transverse tension between the chamfered edges 20. These faces are then engaged by the axially extending steel strips 29 which are carried on a ring 25 rotated by the rotating mandrel. This ring when at rest is supported by two peripherally grooved rollers 26 carried by a stationary annular plate 2. The steel strips 29 force the tube walls into the concave faces 19 of part 18 to form concave tube walls ; the purpose being to compensate for the elasticity of the walls, which are almost flat when they reach said rods 22 which are adapted to serve as supports for the tube when engaged by a saw.

Title: Improvements in and relating to treatment of metals and alloys to protect them from corrosion
IPC: C23C22/33
Filed: 1932-03-02
Abstract: Metals and alloys, e.g. iron, steel, aluminium, or aluminium alloys, are treated to protect them from corrosion by immersion in a hot or boiling aqueous solution of phosphoric acid and one or more of the chromium compounds chromic acid, chromic anhydride, chromates, and dichromates.  The treatment is stated to remove occluded hydrogen from the surface of the metal.  The treatment may be applied to non-ferrous metals and alloys, e.g. aluminium alloys, which have been treated by the process described in Specification 396,746, the original phosphate coat being reinforced by the deposition of chromium phosphate.  Steel tools, e.g. drills and cutters, may be treated by the process to remove the surface hydrogen to render the cutting edge less susceptible to corrosion-fatigue.

Filed: 1921-02-25
Abstract: 181,070. Pollock, S. A. Feb. 25, 1921. Commutator switching-arrangements.-In a rectifying- system, particularly adapted for load circuits containing storage batteries or other sources of back electromotive force, each positive and negative half - wave of current passes in series through the polarized armatures d, c of two relays D, E, the electromagnets of which are energised by currents having a phase difference for the purpose of interrupting the load circuit during the period of each half - wave when the applied voltage is equal to or less then the back electromotive force of the load. In the arrangement shown in Fig. 1, the windings D<1>, E' o! the electromagnets are energized in shunt circuits connected to the alternating-current source A, and the phase differences are produced by capacities F, G, of such a value that the angle of lag between the current and the applied electromotive force in one circuit is equal to the angle of lead in the other circuit. The alternating-current source A is connected to the primary winding a of a transformer with two secondary windings b, c. which are a.lternately connected to the battery or other load O through contacts b<1>, b<2> or c<1>, c<2> on the relays. The connections to the load circuits are only completed when both armatures d, c occupy similar positions, which, owing to the phase differences in the currents energizing the windings D<1>, D<2>, only occurs during a part of each half-wave of the alternating-current. In a modification, Fig. 2, the phase differences in the electromagnetic fiuxes are varied in accordance with the actual back electromotive force existing at any moment. For this purpose a third relay R is provided, with a winding R<1> connected in shunt with the alternating-current circuit through a resistance or reactance s. A polarized armature t of this relay connects the battery O alternately to windings D<2>, E<2> and D<3>, E<3> on the relays D, E. These windings are arranged to increase the angles of lag and lead in the electromagnets of the relays D, E by equal amounts, the actual value of the increases depending on the back electromotive force of the battery. In this arrangement, the capacities F. G in the circuits of the main windings D<1>, E<1> of the relays D, E are of such values that the currents in these windings are in phase with each other. The currents in the windings energized from the relay R are in Quadrature with the currents in the windings D'. E', the windings E<2>, E<3> being connected in reverse direction to the windings D<2> D<3>. Specification 119,081 is referred to.
Patent GB-620744-A (GB)
Title: A process for preparing 2-amino-thiazole derivatives
IPC: C07D277/44
Filed: 1940-04-10
Abstract: Di-acyl derivatives of 2-amino-thiazole in which the acyl groups are p-acylamino-benzene-sulphonyl groups are obtained on acylation of one molecule of 2-amino-thiazole with more than one molecule, preferably at least two molecules, of an active acid derivative of p-acylamino-benzene-sulphonic acid in the presence of either alkali bicarbonates, or aqueous alkali, e.g. sodium hydroxide, solutions, or dimethylaniline.  It is stated that one of the acyl groups is attached to the amino nitrogen atom and the other to the nitrogen atom of the nucleus and that on hydrolysis with alkalis the latter acyl group is removed and the former converted to the free p-amino-benzenesulphonyl group so that a mono-p-amino-benzene-sulphonyl-2-amino-thiazole results.  The acylation is preferably effected in the presence of a diluent such as acetone and with a considerable excess of acylating agent above the theoretical requirements of two molecules.  Mono-acyl derivatives which may be formed in small quantities are removed by washing with aqueous alkalis.  As acylating agents sulphonyl halogenides, e.g. p - acetamino - benzenesulphonyl - chloride are preferred.  The 2-amino-thiazoles may be substituted in the heterocyclic ring with alkyl or aryl groups as in e.g. 2-amino-4-methyl- and 2-amino-4-phenyl-5-methyl-thiazole.  In examples: di-(p-acetylamino-benzenesulphonyl)-2-amino-thiazole is obtained by treating 2-amino-thiazole with p-acetamino-benzene-sulphonyl chloride in the presence of (1) sodium bicarbonate and dry acetone; (2) acetone and 2N-aqueous sodium hydroxide; and (3) dry acetone and dimethyl-aniline; and is then hydrolyzed with aqueous sodium hydroxide to p-amino-benzene-sulphonyl-2-amino-thiazole.  By similar methods it is stated that 2-amino-4-phenyl-5-methyl-thiazole and 2-amino-4-methyl-thiazole may be acylated, the latter compound yielding di-(p-acetylaminobenzenesulphonyl)-2-amino-4-methyl-thiazole which on hydrolysis with 10 per cent sodium hydroxide yields p-amino-benzenesulphonyl-2-amino-4-methyl-thiazole.
