Abstract: 323,947. Tait, W. H., and Cave, L. C. H. Feb. 8, 1929. Revolvingcarrier apparatus; electrodes; connections; electrodes, moving; metals and alloys, depositing. - Electrolytic apparatus for coating gramophone record dies with metal, of the type comprising a flat disc carrier to hold a number of record members and capable of axial rotation above an annular anode whose outside diameter is much larger than that of a record member, is characterized in the provision of means for effecting fine adjustment of the clearance between the anode and cathodes. An annular anode 2 in a single piece or built up of strips or plates or the like, and whoee radial thickness is approximately equal to the diameter of a record member, is supported on suitable insulators 3 in an electrolyte bath 1, Fig. 3. The record members 4 are detachably supported by and in electrical contact with holders 6 on the lower face of a rotatable disc or annular plate 5 of insulating material or of metal coated with such material, the disc being on the same axis as the anode but narrowly spaced therefrom. The holders 6 are connected by leads 7 to a common member 8 engaged by a brush or other suitable contact 10. A central hub 12 formed in the disc 5 is threaded on to the upper end of a rotating shaft 9 and is engaged by the set screw 12a. The gap between the anode 2 and cathodes 4 may be adjusted by means of the thread on the shaft 9, or by any other type of screw-feed adjustment, or the shaft 9 may engage in a footstep bearing capable of vertical adjustment as, for example, by engagement with a cam. A radial gap equal approximately to the diameter of a record member is formed in the anode. Fig. 3 illustrates a method of supporting the members 4 in the carrier 5. The carrier is provided with circular holes 23, each hole having an annular ledge 24 upon which rests the ledge 25 of a disc 26 of insulating material. A member 4 is supported by the ledge of a circular metal ring 27<a>, the ring being detachably affixed to the disc 26 by bolts or studs 27b and nuts 28. One or more of the bolts 27b are electrically connected to the appropriate terminal, and the ring 27a is covered with insulating material except for the upper surface of the ledge in contact with the member 4. Turn buttons 29 may be provided to secure the members 26 in position. Instead of being stationary, the anode may be moved relatively to the cathode.

The thiazole may have methyl, ethyl or phenyl substituents, or may be a benzthiazole optionally substituted by nitro or hydroxy groups. The quinone may carry non-interfering substituents such as alkyl, alkoxy, nitro or hydroxy groups. Suitable starting materials are listed.  Examples show the preparation of 2-(2-benzthiazylthio) -, 2 - [2 - (41 : 51 - dimethylthiazyl) - thio]- and 2-[2-(41-methylthiazyl)-thio]-1 : 4-dihydroxybenzenes.  As a side reaction some disulphide is formed and some of the product is oxidized to a quinone; the latter then combines with a further molecule of 2-mercaptothiazole to give a di-substituted hydroquinone.

Title: Improvements in or relating to pulse-carrying circuit arrangements
IPC: G01R31/30
Filed: 1959-02-11
Abstract: 917,119. Electric selective signalling systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 11, 1959 [Feb. 14, 1958], No. 4782/59. Class 40 (1). [Also in Group XXXIX] Bi-stable cores are used to detect false signals in a two-out-of-five code transmission system. The five signalling wires are connected to a common output giving a resultant pulse of two units strength. Taking i/2 as unit current, the arrangement detects signals of 3i/2 or more and signals of i/2 or less. Pulses from two sources 50, 51 are tested by cores 52, 54 and 53, 55, respectively. Core 54 (or 55) has a continuous bias of i/2 from source 65. The i/2 read-out pulse from source 64 at time t2 together with the i/2 bias gives an effective read pulse of i setting the core to " 0." In view of the i/2 continuous bias, a signal i from 50 at t1 is insufficient to switch 54 to " 1 " but a signal of 3 i/2 will do so. The output signal is amplified at 68 and gated at 81 during interval t2. Core 52 (or 53) is set to " 0 " by source 66 at interval t4. Core 52 remains in state " 0 " if the signal pulse from 50 is i/2 (less than i) but is switched to " 1 " by the read-out pulse i from 63 at interval t2. The gate 81 is open at time t2 to gate the output signal on 74. Core 60 is used to transmit a confirmatory signal at time t3 if there is no error signal. Thus 60 is set " 1 " by the reset pulse from source 66 at time t4 and is restored to " 0 " by an error signal in lead 74 at time t2. If there is no error signal, the core 60 is restored to " 0 " by source 67 at time t3 when the gate 82 is open to accept an output pulse induced in lead 74. Cores 56 to 59 compensate for parasitic pulses induced in cores 52 to 55.

Abstract: 701,987. Manufacture of cup-like articles. MILKFILLERS, Ltd. Feb. 28, 1952 [Feb. 28, 1951], No. 4894/51. Class 100 (2) An apparatus for producing cup-like articles such as bottle caps comprises a punch 1 which can reciprocate to and from a fixed die or former 2, an embossing member 4 removably secured in a recess 3 in the die so as to be capable of embossing an inscription on an article while it is being formed, an ejector member 9 slidable to protrude into the recess 3 to eject the embossmg member, and an operating plunger 10 which protrudes from the side of the die and is slidable against the action of a spring 12 to engage a cam surface 10a thereof with the ejector member so as to urge it into the recess 3 and eject the embossing member. The apparatus shown is for producing bottle closures from a strip of aluminium foil, the punch and die co-operating to first punch out a disc and then press a peripheral portion around the die to form a cup. The member 4 is held in the recess 3 by a spring retaining ring 5 located in a groove in the member. The members 9 and 10 are accommodated in bores 7 and 8, the member 10 being urged outwardly by spring 12 and limited in movement by a shoulder engaging a stop 13, and bevelled at 10a to coact with the part spherical lower end of the member 9.
