Title: Improvements in or relating to blast etching machines
Inventor: MACMILLAN WILLIAM ROBERTSON
IPC: B24C9/00
Filed: 1965-03-01
Abstract: 1,067,943. Blasting. TILGHMAN WHEELABRATOR Ltd. Feb. 24, 1966 [March 1, 1965], No. 8616/65. Heading B3D. A blast etching machine comprises; (a) means for providing a stream of air under pressure; (b) means for controllably introducing abrasive particles into the stream; (c) means for projecting the abrasive-containing stream against a workpiece over substantially the full width of the workpiece; (d) means for moving the workpiece relative to the projecting means; and (e) means for separating the spent abrasive and air and recycling them for further use. In a machine for providing a fine matt finish to materials such as glass, tin foil, stainless steel and aluminium sheet, the work is fed through the blasting zone (e.g. at 1-3 feet/minute) by rollers 14. A fan 4 operating at low pressure (e.g. 27<SP>11</SP> S.W.G.) and high volume (e.g. 640 cubic feet/minute) and driven by an electric motor (e.g. at 2900 r.p.m.) delivers air through a duct 6 to a fish tail 7 located above a mixing box 8 extending across the whole width of the rollers. Abrasive (e.g. aluminium oxide, glass beads, stainless steel, aluminium, brass or copper preferably having a grain size 200- 400 B.S. mesh) is stored in a hopper 11 having a feed slot 12 controlled by a gate valve and opening into a funnel 13 extending across the full width of the mixing box. Abrasive entrained in the air passes through a slot in the base of the mixing box extending across the full width of the rollers. Spent air and abrasive pass to a hopper 17 below the rollers and thence by duct 19 into a cyclone 10 the air outlet of which is connected by a duct 9 to the suction side of the fan 4. Abrasive separated in the cyclone 10 builds up until its weight is sufficient to open rubber flap valves and fall into the storage hopper 11. A bleed duct 20 connected to the duct 6 from the pressure side of the fan 4 communicates with an exhaust box containing a filter. The fan casing is thus kept under slight suction to minimize dust leakage, and dust which is too light to be separated in the cyclone is removed. A Rootes blower or air compressor may be used instead of the fan.

Title: Improvements in the production of chloramino-s-triazines
Inventor: GRAUER THEODOR
IPC: C07D251/50
Filed: 1968-02-23
Abstract: 1,222,102. Chloramino - s - triazines. J. R. GEIGY A.G. 23 Feb., 1968, No. 8790/68. Heading C2C. Chloramino - s - triazines containing one or two amino groups, optionally substituted by organic radicals, are obtained by reacting cyanuric chloride with ammonia or water-soluble primary or secondary amines in the presence of acid binding agents and in aqueous reaction media which are mixtures of water and inert partially water-soluble aliphatic ketones, e.g. methylethyl ketone, methyl - n - propyl ketone, methyl - iso - propyl ketone and diethyl ketone. The acid-binding agent may be an oxide, hydroxide, carbonate or bicarbonate of an alkali metal or it may be provided by a molar excess of the water-soluble amine reactant. The production of chlorodiamino - s - triazines may be effected in two stages, e.g. using a molar excess of amine in the first stage and effecting the second stage by the addition of a separate acid-binding agent, in which case unsymmetrically substituted triazines may be obtained by using two different amines as reactants.

Abstract: 925,844. Massage appliances. A. WINKLER. March 9, 1962, No. 9192/62. Class 81 (2). [Also in Group XXIII] An appliance for massaging the teeth and gums comprises a hollow handle 1 carrying a rotating massage member 20 and means for supplying water and a treating fluid to the member. In the form shown, the member 20 is driven by a water turbine 8 through a shaft 9 and bevel gears 10, 11. At the same time, part of the water from the turbine casing passes to the space around the shaft 9, through apertures 17 in the surrounding sleeve, to a chamber 18, whence it passes through a duct 19 to the bevel housing and so through a central bore in the shaft 12 to the massage member 20. The outer wall of the chamber 18 is formed by a rubber sleeve 21 which thus separates it from a second chamber 22 into which medicament is introduced through a filler 23. With this arrangement the water pressure, in chamber 18, is communicated to the medicament chamber, the contents of which are consequently forced out through a second duct 24 to mix with the water stream flowing to the member 20. An adjustable cock, as 24a, may be fitted in each of the ducts 19, 24 to determine the relative proportions of water and medicament. In one modified form of the device the axis of the massage member is aligned with that of the turbine while in another, the medicament chamber is separate from and mounted above, the hand-piece, the liquid from it being withdrawn either by gravity or by an ejector action.

Title: Improvements in and relating to testing apparatus
IPC: G01N3/06
Filed: 1946-03-26
Abstract: 642,887. Automatic control systems for material testing devices. BRITISH THOMSON HOUSTON CO., Ltd. March 26, 1946, No. 9350. Convention date, March 31, 1945. [Class 38 (iv)] In a machine for testing textile strength of materials, the rate at which the load on the specimen increases is maintained constant by controlling the motor extending the material, in accordance with the difference between a signal dependent on the rate of increase of load and a constant signal corresponding to the desired rate of increase of load. The material is held between two jaws 1, 2 so that as the lower one is pulled down by motor 6 the upper one rotates a drum 8 to lift a pendulum 9b whose angular position is a measure of the load on the material. When the material breaks, the pendulum is held in its raised position by a pawl and ratchet device to indicate the breaking load. The drum 8 drives a rotor 15b to generate an A.C. voltage proportional to the load, and this voltage is rectified at 19 to give a D.C. voltage across resistor 20 which is differentiated by condenser 22 and resistance 23 to apply a voltage proportional to the rate of change of load to the grid of valve 39. A.C. in the secondary winding 11b of the mains transformer 11 is rectified at 12 to provide a voltage across resistance 13 proportional to the desired rate of application of the load, and this is applied to the grid of valve 39 in opposition to that from resistance-capacity combination 23, 22. Valve 39 forms part of a phase-changing circuit including diode 40, resistances 32; 33 capacitances 34, 35, so that as the conductivity of valve 39 varies with the difference between the two signals applied to its grid, the phase of the A.C. applied to the grids of thyratrons 28, 29 is varied to alter the voltage supplied over lines 26, 30 to the armature-6b of motor 6 and thus vary its speed to maintain the rate of increase of load constant at the required magnitude. To counter the effect of the R.I. drop in the armature 6b upon starting, a third bias potential is applied to the grid 39c over contacts 46 and is produced by the effect of the armature current at the resistors 41, 44. This bias is removed after a small initial movement of drum 8 by the operation of switch 46. Upon fracture of the test piece the lower jaw 2 is moved rapidly to its lowest position and then returned to its uppermost position.
