Title: Process for acetylating cellulose material
IPC: C08B3/06
Filed: 1928-01-28
Abstract: 310,563. Ogden, S. A. Jan. 28, 1928. Cellulose acetates. - The cellulosic material prepared by the process described in Specification 246,476 is partly acetylated by treating it, either in the dry state or whilst wet with a trace of sulphuric acid, with acetic acid and then heating the product until dry. The partly acetylated product can be treated in known manner with acetic anhyride or other acetylating medium until it is completely acetylated or until the desired degree of acetylation is obtained. No further catalyst is normally required for the acetylation process since there is usually sufficient unremoved sulphuric acid present in the starting material but, if necessary, one 1/2 per cent of sulphuric acid may be added to 100 parts of the material. In an example, one hundred parts of the cellulosic material are mixed with about 2-4 parts by weight of acetic acid according to the strength of the acetic acid, which may be between 40 and 100 per cent, and heated between 40‹ and 100‹ C. until the product is thoroughly dry. The amount of anyhdride required for acetylation is less than the normal.

Title: Ignition circuits for high pressure mercury lamps
Inventor: STRAUCH ERHARD
IPC: H05B41/231
Filed: 1969-01-17
Abstract: 1,254,892. Central systems for operating high pressure mercury lamps. HONEYWELL Inc. 17 Jan., 1969 [20 Jan., 1968], No. 2810/69. Heading H2H. A control means for operating a high pressure mercury lamp comprises means whereby starting pulses are repeatedly applied to the lamp for ignition thereof during such times as the lamp is not ignited. A high pressure mercury vapour lamp QL is supplied from an A.C. source 1-4 by way of a transformer T1 and a rectifier bridge GB, the output of which is smoothed by capacitors C1-C3, the normal running current for the lamp passing through the secondary winding L2 of a transformer T2. The primary winding L1 of this transformer is connectedwhen a thyristor Q1 is made conductive-to a voltage doubling circuit CR3, CR4, C5, C6, R9, R10 which is supplied from a secondary winding on the transformer T1. Control of the thyristor Q1 is by way of a relaxation oscillator circuit comprising a unijunction transistor Q2. A voltage proportional to that across the lamp QL is taken from a voltage divider R5, R6 and applied to the emitter of the transistor Q2. The voltage applied to the bases of the transistor Q2 is derived from a voltage divider R2, R3. When the lamp is not ignited the voltage across the lamp is high and causes oscillation of the oscillatory circuit such that triggering pulses are applied to the thyristor Ql and hence ignition pulses are repeatedly applied to the lamp QL. When the lamp ignites, the voltage thereacross falls to a value incapable of sustaining the oscillations and thus terminating the generation of ignition pulses for the lamp.

Title: Improvements in the manufacture of calcium hypochlorite
IPC: C01B11/06
Filed: 1945-02-05
Abstract: Calcium hypochlorite is prepared by reacting a basic (e.g., dibasic or hemibasic) calcium hypochlorite substantially free from lime with hypochlorous acid substantially free from chloride, preferably in the presence of a slurry of neutral calcium hypochlorite.  The dibasic calcium hypochlorite may consist of particles several hundred microns in diameter and 1-5 microns in thick-per cent. of the diameter or of particles 20-50 microns in diameter and1-5 microns in thickness, and may contain water (e.g., 14 per cent.) and be washed to less than 0.5 per cent. calcium chloride by water or a solution of calcium hypochlorite.  Preferably, the basic hypochlorite and acid are added simultaneously to a slurry of neutral hypochlorite while stirring, but they may be admixed at a temperature of -15 DEG C., and subsequently added to the neutral slurry kept at ordinary temperature.  When a slurry is made and is filtered to produce solid calcium hypochlorite, the filtrate may be converted into the dibasic hypochlorite by treatment with lime and used for a further reaction.

Title: Improvements in protective equipment for winding and haulage installations
IPC: B66B5/06
Filed: 1946-01-31
Abstract: 604,819. Haulage control. WORRALL, R. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 31, 1946, No. 3131. [Class 78 (v)] Winding control means includes a mercury switch 1 which is so mounted on a carrier 3 rotated in proportion to the winder speed that at a predetermined speed it is actuated by centrifugal force acting against gravity bias on the mercury and causes the speed to be reduced ; and means whereby the predetermined speed may be varied in accordance with the position of the cage. In the diagram, switch 1 is positioned slopingly on pivoted arm 2 with counterbalance 5, and the pivotal support of the arm is positional radially on disc 3 which is driven by gears from driving sprocket 9. The end of arm 2 is supported and adjusted by rod 6 passing through hollow shaft 4, rod 6 is supported adjustably by lever 7, and lever 7 is actuated by cam 8 which also is driven by gears from winding sprocket 9. Cam 8 which is shaped in accordance with cage position, thus controls the inclination of arm 2 and therefore the speed unit of the winder at which the mercury moves against gravity and actuates the switch to reduce the speed of the winder. Switch 10 is an additional overwind switch. Alternatively, the speed control switch may be normally inoperative, but be rendered operative over certain portions of the run by a limit switch operated by the cage, or by a limit switch actuated by the winder drum. Several switches may be mounted on the same or different rotating discs to operate from different cams at differing positions of the cage. The switch may also be made sensitive to acceleration as well as velocity by mounting it obliquely to the radial position on the rotating disc.
