Title: Improvements in or relating to the speed regulation of alternating current induction meters
IPC: G01R11/36
Filed: 1929-07-30
Abstract: 318,857. Blathy, O. T. Sept. 10, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Induction motor meters.-An adjustable magnetic bridging- member is inserted in or adjacent to the air gap of the magnetic shunt of the voltage magnet so that the reluctance of the air gap can be varied. As shown the magnetic shunt f for the voltage magnet b surrounds the magnet in the form of a casing, so that an air gap is formed between the polepiece c and the casing f. A screw h, of magnetic material, is screwed into the wall e of the shunt casing f so that its disc-shaped head i extends into the air gap g between the pole-piece c and the wall e. By adjusting the screw h the magnetic reluctance of the gap g, and consequently the speed of the meter for a given load, may be varied. In a modification, the head i is omitted and the free end of a spring finger extends into the airgap g and is adjusted by the screw h. In another form, a non-circular disc is rotatably adjustable on a pin secured to the wall e, so that a greater or. smaller part extends into the airgap. In another construction a magnetic member is rotatably adjustable about a screw on the front of the pole shoe c, and has a portion bent over at right angles forming a pole face which can be moved nearer to or further from the wall e. In a modification for a two-limbed voltage magnet having horns with an airgap between them forming the magnetic shunt, a brass screw with an iron head is screwed between the ends of the horns.

Title: Improvements in or relating to the polymerisation of ethylene
Inventor: DOBSON LESLIE
IPC: C08F10/00
Filed: 1953-08-26
Abstract: In a process for the polymerization at elevated temperature and pressure of ethylene alone or admixed with one or more other compounds having at least one ethylenic double bond, the ethylene used contains up to 2 per cent ethane but is substantially free from other impurities such as saturated and olefinic hydrocarbons, permanent gases, aldehydes, ethers and alcohols.  A catalyst, e.g. oxygen, benzoyl peroxide, di-t-butyl peroxide or ammonium persulphate may be present.  The polymerization may be carried out in aqueous or other liquid medium at 150 DEG  to 300 DEG  C. and above 500 atmosphere pressure.  The presence of impurities is avoided by controlling the dehydration of ethanol, followed by adsorption, e.g. by water scrubbing and fractional distillation (see Group IV (b)). Specifications 471,590, 497,643, 578,584 and 579,938, are referred to.ALSO:Ethylene, containing up to 2 per cent ethane but substantially free from other impurities such as saturated and olefinic hydrocarbons, permanent gases, aldehydes, ethers and alcohols is prepared by dehydrating ethanol by passing the vapour through a catalyst, e.g. gamma alumina packed in tubes.  The ethanol vapour is introduced, preferably at 325 DEG  to 375 DEG  C., to a catalyst surface at 425 DEG  to 475 DEG  C., and the ethylene and impurities leave at 350 DEG  to 400 DEG  C. when the catalyst surface temperature is reduced by 10 DEG  C.  The remaining impurities are removed by water scrubbing and fractional distillation.  Polymers and interpolymers of the ethylene may be prepared at elevated temperature and pressure in the presence of a catalyst.  Specifications 471,590, 497,643, 578,584 and 579,938, are referred to.

Title: Improvement in method of reclaiming rubber and fabric from scrap
IPC: C08J11/20
Filed: 1926-09-25
Abstract: 274,797. Hercules Powder Co., (Assignees of Smith, L. T.). July 20, 1926, [Convention date]. Devulcanizing rubber. - In the reclaiming of rubber and fabric from scrap a terpene derivative mixture is used having a boiling point range of 160-200‹ C. and a specific gravity of 0.86. This derivative may be the fraction of the extraction of pine wood distilled between 160-200‹ C., and consists mainly of dipentene, but also contains pinene, terpinen, terpinolene, fenchene, camphene, cymene, menthane and limonene. As solvent may also be employed pine oil which has been heated with a dehydrating agent such as fuller's earth, iodine, or sulphuric acid. According to an example, one part of scrap rubber is heated to 100-180‹ C. with 1-5 parts of solvent as above until dissolved, and is strained through a screen. The fabric remaining on the screen may be heated again with further solvent. The solution, after further straining, is distilled to remove the solvent with which the sulphur has combined. The solvent may be freed from sulphur for future use by fractional distillation or by heating with caustic soda.

Contamination of rollers used in the treatment of cloth e.g. dyeing, is prevented or reduced by keeping the temperature of the roller surface adjacent to the dew point of the atmosphere around the roller. This may be achieved by passing a heating medium within the roller which is formed of a non- corrosive metal, e.g. stainless steel provided with a coating of hard chromium plating. Each batch of cloth may be connected to a cleaning band which has a cleaning fluid absorbed therein and which cleans the roller surface as it passes there over. The cleaning band may be coated on each side with a spongey material. Water spraying apparatus may be located relative to the roller so that water can be sprayed onto the cleaning band before it passes over the roller surface.

Classes 44 and 65 (1) In a refrigerator cabinet, cupboard or the like an apertured catch plate 2 on the door 1 engages in a hole or slot 3 in the door post and a sliding bolt 6 is provided within the door post, which is engageable by spring means 21 in the aperture of the catch plate by longitudinal movement thereof, whilst a pedal lever 9 projects from the lower part of the cabinet, cupboard or the like, and is adapted to effect longitudinal withdrawing movement of the sliding bolt from the catch plate. The bolt 6 is connected by a rod 7 to a pedal lever 9 and the spring means 21 is trapped between a collar on the rod 7 and a bracket 5 projecting from the wall of the cabinet, cupboard or the like. The bolt is latched in the disengaged position by a detent 22 which is urged by a spring 25 into a notch below the bolt head. The detent is mounted on a pivoted arm 23 which is engaged by the end of the catch plate 2 when the door is closed to release the detent from the notch in the bolt so that the bolt can engage the aperture in the catch plate.
