Title: Improvements in and relating to a method of and a device for grinding
Inventor: WILSON JOHN CLIFFORD
IPC: B24B53/00
Filed: 1949-02-17
Abstract: 663,227. Dressing grinding-wheels. THOMPSON GRINDER CO. Feb. 17, 1949, No. 4347/49. Class 60 A grinding-machine has a grinding-wheel 22 arranged in alignment with two spaced dressing rolls 32, 46 so that by moving the grinding wheel and the dressing rolls in a single plane relative to each other the grinding wheel may be positioned opposite either of the dressing rolls. The dressing rolls are mounted on the table 12 of a surface grinder which is the same as that described in Specification 658,306. The roll 32 is used for routine dressing until it becomes worn when the roll 46 is positioned opposite the grinding wheel by moving the table 12. This movement causes a cam on the table to open-circuit and dynamically brake the grinding wheel motor after which downfeed is manually imparted to the grinding wheel until it is in contact with the roll under pressure. The roll is now rotated by a motor 31 and further intermittent down-feed is automatically applied to the wheel by its feed mechanism until a limit switch is opened to stop the feed. At this point, the wheel is raised either manually or by coupling its feed mechanism to an electric drive and the roll 32 which is rotated by a motor 30 is brought opposite the wheel. The latter is rotated at grinding speed as it is brought into contact with this roll. When the feed limit switch is again operated, the wheel is rapidly raised clear of the roll to prevent the formation of a flat on the latter.

Abstract: 644,933. Valve gating circuits ; radio direction-finding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 17, 1948, No. 4669. [Classes 40 (vi) and 40 (vii)] In a circuit for sequentially reversing -the phase of a H.F. signal, a switching voltage and the H.F. signal are applied to different control electrodes of two valves which are alternately rendered conducting by the switching voltage, to connect their input circuits to a common output and the currents in the circuits are maintained equal by means of a common feed impedance. The Figure shows a circuit for use in a radio direction-finder of the switchedcardioid type in which the signal from a loop aerial (not shown) is applied across the tuned circuit 1. Valves V1 and V2 are alternately rendered conducting by successive positive and negative going half-cycles of the switching voltage applied from terminals 6 to the suppressor grids of the valves so that the input signal appears successively in reversed phase across the output tuned circuit 5. The currents in the valves V1 and V2 are maintained substantially equal by the common feed-back impedance 9. In a modification, Fig. 3 (not shown), resistors in the suppressor grid circuit limit the effect of suppressor grid conductance during the positive half-cycles of the switching voltage.

Filed: 1926-02-18
Abstract: 247,981. Poulsson, T. H., (Assignee of Hamm, W. F.). Feb. 18, 1925, [Convention date]. Steering-gear.-In automatic steering-gear of the kind in which two magnetic compasses operate the steering gear through electromagnets, of which one acts for variations of course to port and one for variations to starboard, provision is made for adjusting at least one of the compasses in relation to its north direction, and a member, such as an electromagnetic relay, is incorporated for preventing control of the steering gear when the corresponding contacts of both compasses are closed simultaneously, as when the ship is rolling. Electric lamps are also coupled to the controls for indicating the actual course in relation to the set course. The compasses 1, 2, Figs. 1 and 5, are mounted on frames 66, 67 which are adjustable by worm gears 71, 72 and 74, 75 respectively for relative adjustment and for setting a new course. The card 3 of compass 1 has a projection 13 which engages a pivoted lever 12 carrying on a bar 11 four contacts of which the centre ones dip into cups 6, 6, Fig. 4. One outside one touches the material in the cup 5 and the other one is short of the material in the cup 7. On the card turning counter-clockwise the lever is swung, to break the contact 5, and further turning makes the contact 7, whilst on turning clockwise, the contact 5 is merely further immersed. The compass 2 is similarly fitted, but with the contacts of opposite hand. The circuit includes six electromagnets 25 - - 30, five electric lamps 31 - - 35, two regulating resistances 36, 37, and two electromagnets 38. In the neutral position, the circuit which includes the lamp 33 is complete, and the lamp 33 indicates that the ship is on its course. Upon small deviation, one of the lamps 32 or 34 is lit and the magnets 26 or 27 are energized to turn the rudder and restore the course. On a larger deviation one other of the, lamps 31 or 35 is' also lit and the magnets 28, 29 or 25, 30 are energized. When the ship rolls, movements of the corresponding contacts of the two compasses either are both closed or both open together, in the former case the magnets 38 operate to cut out the circuit to the magnets of the steering gear. Specification 214,642 is referred to.

Abstract: 470,762. Electrolysis. DELAVENNA, L., and MAILLARD, J. Feb. 18, 1936, Nos. 4958 and 4959. Convention dates, Feb. 25, 1935 and Jan. 7, 1936. [Class 41] A saturated solution of sodium chloride is electrolyzed under pressure and with high current density, e.g. 12-18 amps. per sq. dcm., in a cell 1, Fig. 1, provided with a rising pipe 7 and a falling pipe 6 connected at the top by a vessel 11. Circulation is effected by the ascent of hydrogen through the pipe 7. Saturation is maintained by the addition of fine crystals of sodium chloride through the openings 12 and 13, this, together with cooling in the vessel 11, producing a precipitation of sodium chlorate crystals which collect in a basin 14 provided with a tap 16. The pipes 6, 7 may be provided with cooling jackets or cooling coils may be arranged in the pipes or in the cell 1. Hydrochloric acid may be added to the electrolyte continuously or intermittently preferably at the same temperature as the electrolyte ; the acid together with the saturated brine may be introduced at the cell level by means of a pump. The cell 1 is provided with a plug 3 through which the pipes 6, 7 pass, the end of the pipe 7 being flush with the lower side of the plug and the end of the pipe 6 projecting below it. The pipes 6, 7 and the vessel 1 may be cooled. A filter may be arranged in the pipe 7, or in a byepass thereto. Taps 9, 10 are provided for sampling. The anode 2 consists of a cage, e.g. of platinum wire, the vessel 1 constituting the cathode. The apparatus and the circulating system may be used for other electrolysis processes in which a precipitation of products from a saturated solution is effected. In a modification, Fig. 3, the cell 1 is of moulded material and the anode consists of graphite bars 2 alternating with cathode bars 17. In this form circulation is caused to proceed in the direction shown by reason of the asymmetric shape of the bottom 18. In other modifications the fall pipe 6 enters the cell at the bottom or the side. The apparatus may be used for the production of hypochlorites, the solution being continuously removed at a suitable part of the circuit when a sufficient yield is attained, and make-up liquid added, the circulating electrolyte always, however, being maintained saturated with sodium chloride.
