Title: Improvements in and relating to the acceleration of the vulcanisation of natural andartificial varieties of rubber
IPC: C08K5/00
Filed: 1931-04-23
Abstract: Thioamine derivatives.--Vulcanization accelerators for natural and artificial rubber and containing the grouping <FORM:0377730/IV/1> are obtained by the action of N-halogen compounds of secondary amines on vulcanization accelerators containing the group <FORM:0377730/IV/2> Alternatively such compounds may be prepared by the action of secondary amines on disulphide derivatives of vulcanization accelerators containing the grouping <FORM:0377730/IV/3> Secondary amines such as dibutylamines, piperidine, hexahydroethylaniline or morpholine may be employed, and accelerators suitable as starting materials are mercapto-thiazoles, -oxazoles, -thiodiazolthione, dithio acids, dithiocarbamic acids or xanthic acids.  Thus N-chlorpiperidine may be reacted with the potassium salt of 3 - phenyl - 5 - mercapto - 3 : 4 - thiodiazolthione to give a thiopiperidide derivative, and the reaction products of N-chlorpiperidine, N-chlormorpholine, dimethylchloramine and dibutylchloramine with mercaptobenzthiazole are also mentioned. Alternatively piperidine may be reacted with 2 : 2<1>-dibenzthiazyldisulphide in toluene solution to give a 2-thiopiperidide derivative.ALSO:The acceleration of the vulcanization of natural and artificial rubber is effected by the application of products obtainable by replacing the sulphydryl group ­C-SH in accelerators containing the same by the grouping <FORM:0377730/V/1> A favourable critical temperature in the vulcanization process is obtained by the introduction of this group into such accelerators as mercaptothiazoles, -oxazoles, -thiodiazolthione, dithio acids, dithiocarbamic or xanthic acids, and the activity of the products can be increased by employing them in conjunction with other suitable accelerators.  The products may be prepared by the action of N-halogen compounds of secondary amines on accelerators containing the ­C-SH group.  Alternatively the disulphides R-SSR of mercapto compounds RSH exerting an accelerating action may be reacted with secondary amines such as dibutylamine, piperidine, hexahydroethylaniline or morpholine.  Thus N-Chlorpiperidine reacts with the potassium salt of 3-phenyl-5-mercapto-1 : 3 : 4-thiodiazolthione to give a thiopiperidine derivative, and 2 : 21-dibenzthiazyldisulphide may be reacted with piperidine in toluene solution to give a 2-thiopiperidide derivative of benzthiazole.  Data illustrating the accelerating action of these two products in the vulcanization process are given, as well as the action of the reaction products of mercaptobenzthiazole and N-chlormorpholine, dimethylchloramine, dibutylchloramine and N-chlorpiperidine, in the latter case the product being used alone and in conjunction with (1) diphenylguanidine and (2) dibenzthiazyl-2 : 21-disulphide. Artificial varieties of rubbers such as the masses derived from butadiene hydrocarbons may be similarly treated with equal effect.

Abstract: 1,080,364. Diffraction gratings. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 23, 1964 [March 28, 1963], No. 12406/63. Headings G2J and G2M. Gratings for "soft" X-rays are produced by providing a support having an optically finished surface with a series of solid parallel strips to form a grating of the desired line spacing, and then making a negative cast of the grating. A coating of metal, e.g. aluminium, on an optical glass surface may be ruled by a diamond tool and then etched to remove residual metal from the ruled grooves to form a grating pattern in relief. The structure so produced may be coated with a thin gold layer which is cemented to a back-plate by an adhesive, e.g. an epoxy resin, and finally, when the resin is set, the back-plate carrying the adhesive and the gold is removed from the original to form the required diffraction grating. Other gratings may similarly be produced from the same "master". The "master" may be produced by the use of a photographic resist and the cast produced as above.

Abstract: 636,487. Magazine gramophones. PAILLARD & CIE SOC. ANON., E. May 9, 1947, No. 12562. Convention date, June 5, 1946. [Class 40 (ii)] A record magazine for a gramophone comprises two or more shafts 5, arranged around the turntable 1, each shaft being rotatable between limits and carrying a set of main supporting members 15 and also a set of auxiliary supporting members 14 which are angularly displaced from the main set. The arrangement is such that if the shafts are rotated in one direction by operating member 13, the records supported individually by each pair of members 15 fall on to the next lower pair of auxiliary members 14, and when the shafts return to their normal position due to the action of spring 10 the records fall again on to the main members 15. Each record is then supported by the pair of members 15 immediately below the pair by which it was previously supported, and the lowest record has been released on to the turntable. The member 13 may be operated manually or automatically under control of the pick-up. A modification is described in which the auxiliary members 14 are mounted on a sleeve which rotates with shaft 5 but rises and falls during the movement so that the records are transferred from one set of supporting members to the other smoothly.

Title: Automatic electric arc welding apparatus
Inventor: MARSDEN ROY
IPC: B23K9/028
Filed: 1962-04-02
Abstract: 1,031,821. Welding by fusion. SUPERHEATER CO. Ltd. April 2, 1963 [April 2, 1962], No. 12629/62. Heading B3R. [Also in Division H2] In an automatic arc welding machine for joining tubes end-to-end by relative movement of a non-consumable electrode and the tubes, the heat input from the electrode to the tubes is reduced at a predetermined instant during the welding cycle to prevent over-penetration. This is effected by reducing the welding current and/ or increasing the traverse speed. The tubes A, B, Fig. 1, and Fig. 2 (not shown), are located by an abutment 12 and held in chucks 6 of rotary carriers 5 driven in unison by a motor 17 connected to a D.C. supply T6, T7. The output of a three-phase rectifier MR1 is connected to the electrode 7 and to brushes 44 mounted on leaf springs and engaging slip rings 46 on the carriers 5. The rectifier MR1 is supplied by the secondary windings TR1S of a main transformer controlled by a magnetic amplifier MTR having D.C. control and feed back windings. A control ring 27 journalled on one carrier 5 and rotated at a lower speed than the carrier 5 has projections actuating switches MS1, MS2. In operation after a preheat period the motor 17 is started and almost immediately switch MS2 energizes relay RL to drive the motor at a speed determined by resistance R1 and to set the full welding current determined by a resistance R3 in the control circuit of the magnetic amplifier MTR which control circuit is fed through a transformer TR2 from one of the primary windings TRIP of the main transformer. After, say, 270 degree rotation of the tubes, switch MS1 operates relay RL to short circuit resistance R1 to increase the speed of motor 17 and to connect resistance R2 in series with resistance R3 to reduce the welding current. When the weld is completed the tubes are rotated a further 30-90 degrees with steadily reducing welding current. In a two-pass weld, the tubes are halted after one revolution and the current is maintained to raise the temperature. The second pass is performed as described for a single pass weld, but with an increased current. The welding head 8, Fig. 5 (not shown), is water cooled, has a tungsten electrode 7, a ceramic nozzle 21 through which argon and hydrogen are passed and an enclosure 23. A block 24 pivotally mounted on the machine supports the welding head 8 by the cooling water pipes 9. Argon is supplied to the interior of the tubes.
