Title: Improvements in the manufacture of cellulose esters
IPC: C08B3/02
Filed: 1932-04-05
Abstract: Cellulose is esterified in the presence of a hydrohalide acid and a hydrohalide of a nitrogen containing base, and particularly mixtures of hydrochloric acid with ammonium chloride or the hydrochloride of an organic base.  The organic bases used may be methylamine, ethylamine, propylamine, ethanolamine, or the corresponding dialkylamines, aniline, benzylamine, cyclohexylamine, or less advantageously, tertiary bases such as trimethylamine and pyridine. The amount of hydrohalide acid employed is preferably from 5-15 per cent based on the weight of the cellulose, and of the hydrohalide of the nitrogen containing base, up to 50 per cent.  The cellulosic material, which may be pretreated, e.g. according to the process of Specification 263,938, 312,098, [both in Class 2 (ii), Cellulose &c.], or 342,739, is subjected to esterification either in solution, or in suspension in an indifferent liquid, or by the process of Specification 264,937, [Class 2 (ii), Cellulose &c.], in the absence of liquid solvents or diluents.  The following examples are given: (1) Cotton linters pretreated with acetic acid are esterified in a mixture comprising hydrochloric acid, ammonium chloride, acetic acid, and acetic anhydride.  (2) Cotton linters which have been sprayed with concentrated hydrochloric acid and allowed to stand are introduced into a mixture of hydrochloric acid, diethylamine hydrochloride, acetic acid, acetic anhydride, and toluene.  (3) Chemical pulp is boiled with caustic soda solution, washed, and heated with glacial acetic acid.  After cooling, aniline hydrochloride, hydrochloric acid, and acetic anhydride are introduced.  Specifications 207,562, 249,173, 263,939, 326,515, [all in Class 2 (ii), Cellulose &c.], and 395,707 also are referred to.

Abstract: 1,145,420. Current transformers. GENERAL ELECTRIC CO. 29 Feb., 1968 [10 March, 1967], No. 9838/68. Heading H1T. A current transformer comprises a base 10 supporting an insulating column 12, in turn supporting a metal tank 14 through which runs a high voltage primary conductor 40, a secondary winding assembly 50 surrounding the primary 40 disposed within the tank 14; and a tubular metal tension member 18 extending through the column 12, provided with a means to clamp the tank 14, column 12 and base 10 together and compressively preload the column 12. Clamping means may be by a number of studs 30 co-operating with spring washers 36 to clamp flange 34 welded to the bottom of tension member 18 in relation to the base 10. The secondary coils are earthed at one point and are supported by the insulating support 24 which is clamped in position by the aforesaid means. The force produced in spring washers 36 may be varied by adjusting screw means 20 to vary the effective length of tension member 18. Each secondary 50 and 52 has an earthed magnetic core 54 and insulative covering 64, and the whole secondary assembly is enclosed in the grounded metal shielding 60. The tension member 18 serves as a conduit for the leads 66 of the secondary windings. Additional electric shielding 70 and 72 may be provided. The tank and insulating column are filled with sulphur hexafluoride under pressure.

Title: Improvements in or relating to brackets for attaching cap-lamps to miners' helmets
Inventor: HUNT THOMAS ARTHUR
IPC: F21V21/14
Filed: 1963-03-12
Abstract: 1,076,403. Hinges. JOHN T. MOSS Ltd. March 11, 1964 [March 12, 1963], No. 9839/63. Heading B2F. [Also in Division F4]  A bracket for attaching a miner's cap lamp to a miner's helmet comprises a tongue engaging a slot in the lamp or helmet, portions defining a slot for engaging a tongue on the helmet or lamp and means interconnecting the tongue and portions to provide a pivotal frictionally controlled joint for their relative displacement. In the form shown, the first member 1 is angled to provide a tongue 3 to be received in a clip or slot in the helmet and has downwardly depending portions 5 with aligned apertures 6. The second member 2 is U-shaped with aligned apertures 8 and encloses a U- shaped member 10 with aligned apertures 11 and slots 13 which receive pressed-in portions 14 of the member 2. A bolt 7 passes through the apertures 8, 6, 11 and through a spacing washer 16 between the limbs of the member 10 so that the portions 5 of the member 1 are arranged between limbs of the members 2 and 10. The bights of the members 2 and 10 form a slot to receive a tongue on the cap lamp. The tongue 3 can, alternatively, be rigidly secured to the helmet or the members 2 and 10, or the member only rigidly secured to the cap lamp. Control of the pivoting movement is provided by the frictional engagament of members 1 and 2 effected by tightening of the bolt 7, the members being resilient and formed of e.g. sheet metal or plastics material. Also a resilient washer - e.g. of rubber, may be provided between the members and/or their opposed faces may be roughened.

In an internal shoe-drum brake, as shown in Fig. 6, the actuating cams for moving the actuated ends of the shoes 16, 17 to apply the brake also act as abutment surfaces for the other ends of the shoes, but the abutment surfaces for which the centres of curvature are indicated at 24 and 25, are eccentric from the pivotal axes of the cams indicated at 20 and 21, so that both ends of each shoe are simultaneously moved towards the drum, since the levers 22, 23 for operating the cams are linked together. The degree of eccentricity may be adjustable, as shown in Fig. 3, by means comprising a bushing 7 having a part 8 with a slot 81 through which a securing screw is passed. Fig. 8 shows an arrangement in which the brake is fluid pressure actuated, fluid pressure being passed to the actuating cylinders through the pivotal axis of the device 32, this axis 34 being eccentric with the connection 36 of the other shoe. Fig. 9 shows an arrangement using mechanically operated actuator plungers.

Title: Bearing sylicate-gele process for production of metallocene alumoxan cathalisator
Inventor: CHANG MAIN
IPC: C08F4/639
Filed: 1989-03-28
Abstract: This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the slurry, gas or liquid phase polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 10 to about 50 per cent by weight adsorbed water as the catalyst support material. It has been found that such silica gel may be safely added to an aluminum trialkyl solution to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane component of the catalyst system. An alumoxane coated silica gel is formed to which a metallocene may be added. The resulting material can either be used in this slurry state for slurry polymerization or can be used for liquid phase polymerization of olefins.

Title: Fluid heating device
Inventor: NAGAOKA YUKIO
IPC: F23N5/18
Filed: 1985-01-08
Abstract: PURPOSE:To make the detecting part of a fluid heating device simpler by a structure wherein a flow detecting device consisting of a detecting temperature sensor made of a temperature-dependent resistor and a heating temperature sensor to be heated by energizing. CONSTITUTION:When the power supply is put to work and a temperature is set by a user, immediately the maximum flow rate to a heat exchanger 9 is calculated by comparing the signal of a temperature setter 22 and that of an outlet temperature detector 18. Next, when fluid to be heated is supplied to the heat exchanger 9, a flow detecting device 17 detects the flow rate of the fluid to be heated, resulting in causing to supply fuel to a heating device 10 in order to heat the fluid to be heated at the heating exchanger 9. The flow signal of a flow calculating circuit 25 is compared with the set value at a flow setting circuit 24, resulting in displacing a flow control valve 6 by means of a driving device 14 so as to control the flow rate. The motor 12 of the driving device 14 can be rotated in both directions so as to increase and decrease the flow rate by the signal of a flow control circuit 26. Concretely, when the flow rate is larger than the flow rate set at the flow setting circuit 24, the motor 12 actuates so as to close the flow control valve 6, while when smaller, the motor actuates so as to open the flow control valve 6.
