The axis of the shank 22 is inclined downwardly from the recess to effect a downward clamping of the bit into the recess 20. Cutting bits.-The cutting bits are formed as oblique prisms having offset principle faces and oppositely facing cutting edges 7 and 8. The prism has a principle axis 5 contained in an imaginary diagonal plane containing the cutting edges 7, 8, and the axis of the hole 11 is oppositely inclined to the axis 5. The bit has an axis of symmetry passing through opposite diagonal corners about which the said cutting corners are reversed. In an alternative embodiment (Fig. 4) the basic prismatic shape has plunge-cutting extensions 47, 48 formed thereon, the cutting holder stock 56 having a recessed part 70, 54a to accommodate the non- cutting extension 48 thereof. The bit is reversible about its axis of symmetry 53.

Abstract: 1,085,107. Control systems for electron beam furnaces. TEMESCAL METALLURGICAL CORPORATION. Aug. 23, 1966 [Oct. 19. 1965], No. 37672/66. Heading H2H. The beam current in an electron beam furnace is limited to a predetermined value by means of a thermionic diode 14 connected in series between the D.C. supply 16 and the cathode 40 of the electron gun 10 of the furnace 12. The D.C. supply is derived by means of a rectifier from a three-phase A.C. supply 18 whilst the heating current for the cathode 26 of the diode 14 and the cathode 40 of the furnace 12 are derived from a single phase of the supply 18 by means of variable autotransformers 32, 46, respectively. Thus the maximum current flowing through the diode 14-and hence the electron beam current-is limited by selection of the current flowing in the filamentary cathode 26 of the diode.

Abstract: A method of making an ester-imide resin according to any of Claims 1 to 4 of the parent Specification, wherein the ester imide formed contains aliphatic residues derived from one or monocarboxylic acids having 6 to 24 carbon atoms, comprises introducing said residues by reacting the ester-imide resin or one of the starting materials for the preparation thereof with monocarboxylic acid or acids.  Specified monocarboxylic acids are those derived from tallow, olive, soya bean, linseed and coconut oil and 2-ethylhexanoic acid.  The examples describe the preparation of modified polyestermides from: (1) a mixed ester derived from dimethyl terephthalate, glycerol, butanediol and coconut oil and a diimide made from trimellitic anhydride and 4 : 41-diaminodiphenylmethane; (2) a condensate from glycerol, natural fatty acids, isophthalic acid and butanediol, 4 : 41-diaminodiphenyl methane and trimellitic anhydride, and (3) a diimide made from 4 : 41-diaminodiphenyl methane and trimellitic anhydride, coconut oil and glycerol.  The products of the examples are soluble in benzene hydrocarbons, chlorinated hydrocarbons, ketones or esters and may be reacted with cross-linking agents for example amino - triazine - alcohol - formaldehyde condensates and stabilized polyisocyanates.

The acid containing hydrogen sulphide is passed through a first tower packed with active carbon having a surface area of 1000 mg.2-1 and a grain size of 3 mm., in 5-10 minutes.  Excess hydrogen peroxide, e.g. 25-250 mg. per litre is added and the liquid is passed through a second tower packed with active carbon, in 3-6 minutes.  Four organic p  impurities are present, the impure acid may be pretreated by passage through a tower containing active carbon before treatment with hydrogen sulphide.

Filed: 1972-08-19
Abstract: 1399936 Lift door operation OAKLAND ELEVATORS Ltd 15 July 1973 [19 Aug 1972] 39051/72 Heading B8L A lift door operator assembly for controlling the vertical opening and closing movement of a lift car door 30 together with an adjacent lift shaft door 39, comprises an electromagnet 22 mounted on the car door 30 and energizable to couple the door 30 to a pick-up plate 37 on the shaft door 39, an electric motor 1 for reciprocably driving a car door driving pin 14 and safety switches 20, 32 on the car door 30 to sense relative movement between the driving arrangement and the car door generated by the baulking of the closing movement of either door, while the electromagnet is energized, to initiate reversal of the closing movement of the drive arrangement. The pin 14 is journalled in endless chains 12 driven through a chain 6 and sprocket transmission from the motor 1, all mounted on the lift car roof, whereby the pin 14 is reciprocated up and down to open and close the doors. One end of the pin 14 is received in vertical slots 23a in a bracket 23 secured to the top of the car door 30 and during lifting the pin reacts against the top of the slots. The electromagnet 22 is supported on an arm 25 pivoted at 25a to a pivot block 28 on the door 30, and is shaped to have an inclined ramp 25b engageable by the drive pin 14 when it moves downwardly in the slots 23a from its normal driving position, to retract the electromagnet 22 from its operative position, a projection 24 also on the arm 25 actuates a switch 16 to stop the motor 1 when the magnet is retracted. In operation, when the doors are selected to open, the motor 1 is started and the magnet 22 is energized and moves to engage the shaft door 39, the drive pin 14 engages the upper end of the slots 23a and both doors rise until a cam track 31 on the car door 30 engages a switch 10 to de-energize the motor 1 only. When the doors are selected to close, the motor 1 is energized in reverse and the pin 14 lowers the doors until the cam track 31 engages a switch 18 which de-energizes the magnet 22 and changes the circuit so that the lower safety switch 20 becomes inoperable and cannot re-open the doors. As the doors reach their lowered position, the pin 14 moves down the slots 23a causing retraction of the magnet and causing projection 24 to de-energize the motor through the switch 16. If during lowering, the shaft door 39 is baulked the motor reversing switch 32 is operated by a cam 27 on the block 28 which moves against spring bias relative to the bracket 23. If the car door 30 is baulked during lowering the motor reversing switch 20 is operated by a cam 15 on the pin 14 which moves against spring bias relative to the bracket 23. A switch 35 on every shaft door 39 must be closed before the main hoist drive motor can operate and this switch also opens the magnet circuit to permit retraction thereof.
