Abstract: 1,260,674. Temperature responsive actuating elements. FUNDITOR Ltd. April 23, 1969 [April 26, 1968], No.19936/68. Heading G1D. A temperature controller comprises a spring- loaded piston 19 adapted to be moved along a cylinder bore by the thermal expansion of a fluid in a tube 38 and a bulb 40, a sleeve 20 secured to the piston and a seal 22 between the piston and the cylinder bore, the sleeve having a portion of reduced diameter so that during the stroke of the piston the working surfaces of the seal and the sleeve do not slide over any common portion of the cylinder bore working surface. The bore is formed by a sleeve 17 cemented in a body 3 and the spring-loading is provided by a spring 28 which engages the flange 27 of an operating plunger 26. The sleeve 20 is made of nylon whilst the sleeve 17, the piston 19 and the body 3 are made of mild steel, and the seal 22 is made of neoprene. The expansible fluid may be mercury and the element 1 is mounted in a housing 34. Expansion of the fluid in the bulb 40 causes the plunger 26 to rotate a beam 42 about its pivot 37 thus causing a link 43 to extend a spring 461 and a rack 48, connected to the beam by plates 45 and a pin 52, to move upwardly. The rack is biased into engagement with a pinion 50 by a spring 49. A pointer 58 is secured to the pinion 50 so that movement of the rack rotates the pinion thereby moving the pointer 58 over a scale 60 marked in degrees. A second pointer, the position of which on the scale may be pre-selected and an arm carrying a micro-switch are adjusted by an external knob to a position corresponding to the pre-selected temperature. When the pointer 58 reaches this temperature a rod 68 operates the micro-switch to switch off a heating current thus allowing the material in which the bulb 40 is immersed to cool.

Filed: 1962-05-24
Abstract: 1,001,894. Compression moulding device. C. BALLHAUSEN. May 24, 1962 [May 24, 1961], No. 20105/62. Heading B5A. [Also in Division B1] Substances are subjected to omnidirectional compression in a device which comprises a plurality of sector-like pressure transmitters 5c forming a die cavity 1c, means operative to compress the substance in the cavity by axial compressive forces, e.g. two opposed axiallyaligned punches, and means 14-19 for applying radial inward pressure to the sector-like transmitters 5c during the compression operation. A die cavity 1c is surrounded by sectorlike pressure transmitters 5c the cross-sections of which increase in a direction away from the die lc, each sector 5c being made of several different materials 11-13 depending on the pressure applied thereto. The sectors 5c are relatively spaced by gaps 7c of sufficient width to prevent them being forced into contact during pressing. A resilient ring 14 surrounds the ends of the sectors and around this assembly is fitted a constraining ring 15 with an annular groove forming a cavity 16. An hydraulic medium is connected to the cavity which is sealed with ring 14 at 21. Thus hydraulic pressure can be applied in cavity 16 against the ring 14 and is then transmitted through the sectors 5c to the die 1c to prevent radial expansion of the die during the compression operation. The ring 14 is preferably made of graphite which is superficially sealed either by impregnating with a suitable fluid or enclosing in a thin sleeve. It is essential that the outer ends of the sectors are higher than the die 1c. An alternative form of holding the constraining ring 22 and resilient ring 14a to form a cavity 16a is shown in Fig. 3. In other embodiments the pressure to the sectors may be applied by dished springs compressed by the means which operate the punches for the die, Fig. 6 (not shown), and the resilient ring 14 may be omitted and replaced by shaped steel pieces held in place by pins fitted across the flattened ends of the sector-like pressure transmitters, Fig. 5 (not shown).

Title: A process for the production of benzoic acid and benzoates
IPC: C01G37/02
Filed: 1932-07-20
Abstract: Bichromate used as oxidising agent in the process of the oxidation of toluene to benzoic acid is regenerated by treating the chromic oxide-containing residue with sodium chromate and caustic alkali, alkaline earth or alkali or alkaline earth carbonate or magnesia or magnesium carbonate and oxygen-containing gases under pressure.  A similar regeneration may be effected when magnesium bichromate is employed in the first instance as oxidising agent.ALSO:Benzoic acid and benzoates are obtained by oxidation of toluene with bichromates or monochromates at temperatures above 100 DEG  C. and under pressure employing, in addition to the material employed for oxidation, excess bichromate or a further bichromate to neutralise the alkaline substances formed in the course of the reaction.  Alkali, alkaline earth and magnesium bichromates are mentioned as suitable additional bichromates.  The oxidising agent may be regenerated by adding caustic alkali, alkaline earth, alkali or alkaline earth carbonate, magnesia or magnesium carbonate, and subjecting the mixture to oxidation with an oxygen-containing gas under pressure.  According to an example pure toluene is treated with sodium bichromate solution at 250--300 DEG  C. under pressure in sufficient quantity to neutralise the alkali formed during the reaction, and the products are worked up for benzoate and monochromate, the oxidising agent being regenerated by oxidation.
