[Also in Group XXXVI] A terminal construction for a sheathed wire heating element comprises an insulating bushing 6 spacing the terminal pin 2 at the end of the wire heating resistor from the metal tubular sheath 1; the bushing is soldered at 11 to a sleeve 4 hermetically connected to and constituting an extension of the sheath 1, the bushing being also soldered at its recessed outer end 8 to the terminal pin 2. The bushing is metallised at the areas 7, 10 where it is to be soldered. The copper tube 4 is brazed at 5 to the sheath 1. The bushing 6 extends into the sleeve 4 and is separated from the end of the sheath 1 and the mineral insulant 3 therein by a plug 12 of a deformable insulator, e.g. a silicone elastomer. The exposed surface of the insulant 3, e.g. magnesia, is first impregnated with a silicone oil which is then polymerized at 300‹C. The deformable insulator 12 is then placed in the end of the sheath and compressed by placing over the pin 2 a plug of steatite of the same shape as the bushing 6, whereby part of the insulator 12 is forced to flow to the area 13 at the inner end of the sheath. The steatite plug is removed and the bushing 6 is soldered in place.

The emulsion is made by forming the silver halide in a solution or colloidal suspension of the colour former. An emulsion may be subjected to ripening processes with the colour former remaining in the gelatin, thereby permitting grain growth with the colour former still attached to the silver halide crystals. Colour sensitized emulsions containing different colour-formers may be mixed together, or coated in superposed layers, reference in this latter connection being made to Specification 376,795. Alpha-naphthol, paranitrobenzylcyanide and other colour-formers are specified and also developers therefor (e.g. paraphenylenediamines and paramidophenols).

Title: Improvements in or relating to dough-rolling machines
IPC: A21C3/02
Filed: 1964-01-14
Abstract: 1,002,094. Dough rolling. G. A. SEEWER. Jan. 14, 1964 [Jan. 22, 1963], No. 1674/64. Heading B5A. In a dough rolling machine substantially as described in Specification No. 919,750 the pass between rollers 1 and 2 may be adjusted either by means of a hand wheel 9, or by means of a control lever 34, the operation of which also actuates the drive mechanism of roller 1 and controls the relative speeds of the feed and carry off conveyers as is described in the above Specification. The upper roller 2 is suspended from an adjusting shaft 5 by means of eccentrically mounted discs 3 and is vertically guided by guides 6. A pinion mounted upon the shaft 8, of hand wheel 9, engages a gear 11 carried by a shaft 12 on which is mounted a slider 13 comprising parts 13b and 13c. Part 13c carries a pin 13d on which is pivotally mounted a rocker 17 having a central aperture in which a member 15, 15a, mounted upon the adjusting shaft 5, slides. When the hand wheel is turned slider 13 is rotated thus causing rocker 17 to pivot about pin 13d, and member 15 to slide within said aperture and to pivot about the axis of shaft 5. The consequent rotation of shaft 5 raises or lowers the upper roller, the parts 13, 15 and 17 being so disposed that the ratio of the size of the roll gap after adjustment to the size of the roll gap before adjustment, for a given rotation of the hand wheel is constant irrespective of the size of the initial roll gap. In the alternative adjusting mechanism segment 32, journalled to shaft 33 of control lever 34, is provided with a cam portion 37 which co-operates with a roller 38 of a member 39 resiliently pivoted to a member 40, rotatable about shaft 12. When segment 32 is rotated by means of lever 34 the member 39 is pivoted in an anti-clockwise direction as viewed in Fig. 2, bringing pawl 46, carried by member 40, into engagement with serrations 13e on member 13b of slider 13. Further rotation of the lever 34 causes slider 13 to be rotated in an anti-clockwise direction as viewed in Fig. 2 and a consequent actuation of members 15 and 17 resulting in a decrease of the roll gap. A rotatable stop eccentric 50 determines the initial position of the pawl relative to the serrations and this governs the amount of subsequent movement of member 13 and thus the size of the decrease in the roll gap. Releasable means for preventing upward movement of roller 2 during rolling, and means to adjust the lower terminal position of said roller, are provided. If this terminal position of the rollers is reached by rotation of lever 34 before the switch actuating the roller 1 is operated the resilient linkage between members 39 and 40 allows the lever to be further rotated to facilitate said actuation. To change over from adjusting means 33, 34 to handwheel 9 the stop eccentric 50 is turned through approximately 180 degrees to raise the roller 38 clear of cam 39 and thus effectively disengage said means.

Title: Improvements in or relating to the treatment of ricinoleic acid and its esters
IPC: C07C51/00
Filed: 1956-01-18
Abstract: Ricinoleic acid or an ester thereof is pyrolysed in admixture with water vapour to yield n-heptaldehyde and undecylenic acid or an ester thereof.  The acid or ester is preferably admixed with 0.3-3.0 times its weight of water vapour and heated to pyrolysis temperature in a separate zone or dispersed in superheated steam. Heating is effected at 500-700 DEG  C. generally for less than 5 seconds and suitably by passage over or through extended surfaces of heat-conducting material such as steel, graphite or molten lead.  Conditions are preferably such as to give 70-95% decomposition of ricinoleate per pass. Products ar cooled rapidly, freed from water, and fractionated in vacuo.  Esters of aliphatic alcohols of up to 4 carbon atoms are preferred starting materials.  In examples, methyl ricinoleate obtained by alcoholysis of commercial castor oil, isopropyl ricinoleate, castor oil, and ricinoleic acid are treated.
