Title: Improvements in and relating to electric motor control systems
IPC: B60L15/34
Filed: 1935-08-08
Abstract: 461,246. Master control of motors. BRITISH THOMSON - HOUSTON CO., Ltd. Aug. 8, 1935, No. 22420. Convention date, Aug. 8, 1934. [Class 38 (iii)] A multiple-unit control system in which the step-by-step movements of the several controllers Sz are synchronized, comprises two through control lines 6, 7, connected in parallel, contacts in one of the control lines and closing contacts in the other, at each step movement, and each controller having a controlling electromagnet Sa, Sb, which is energized through the driver's controller Sw to initiate a step movement when a circuit through either of the two through control lines is completed. Upon operation of one of a series of direction switches Rw reversing relays are operated and.the remaining switches Rw present operation of corresponding drivers' controllers Sw. When the effective controller Sw is operated to a position " UP ", a controlling electromagnet Sb for each controller is energized through the line 6, the several controllers being initially in their " off " positions, and the several contacts in the line 6 closed. The circuit for the electromagnets Sb includes contacts of motor isolating contactors T1, T2, which are closed as the controller Sw passes to its first position and maintained over a through control line 2. Energization of the control magnets Sb causes each controller to move one step. The contacts in the line 6 are thereby opened and as each controller completes its step movement it closes contacts in the line 7. When all the controllers have completed the step the electromagnet Sb is again energized this time through the line 7. The operation is repeated while the controller Sw is in its position " UP " but if the controller Sw is returned to the position " RUN " the supply to the electro magnet Sb is interrupted and the controllers Sz are not further advanced. By moving the controller Sw to its position " DOWN " the electromagnets Sa are energized and the controllers Sz moved in the reverse direction with similar synchronizing control. When the controller Sw is moved to its " OFF " position the contactors T1, T2, are de-energized and at contacts 441 complete a circuit for the electromagnets Sa to return the controllers Sz to their initial positions. Switches 3<11>, 4<11>, operate as limit switches at the full on and the off positions respectively of the controllers Sz. When a coach is disconnected the lines 5, 7 are bridged at the non-coupled ends of a coach by means of switches K, and a similar bridging is effected if motors are isolated by de-energizing the contactors T1, T2.

Abstract: 797,896. Valves. SAUNDERS VALVE CO., Ltd. Oct. 4, 1956 [Aug. 5, 1955], No. 22615/55. Class 135. In a fluid control valve of the kind having a non-rising spindle 1 with the operating mechanism enclosed in a bonnet 2, the spindle has a longitudinal groove 5 in which slides a graduated indicating member 6, the inner end of the member coacting with a stationary screw thread 8 of a bush 9 in which is secured the bonnet. Rotation of the handwheel 3 attached to the spindle by a pin 4 causes the indicator to move up or down. The pitch of the thread 8 may be varied so that the movement of the member 6 is any desired proportion of the movement of the closure member. The member 6 is made in a soft ductile material so that closing the valve to draw the member 6 into the groove 5 will straighten the member if it has been bent. Specification 516,526 is referred to.

[Class 38 (ii)] An adjustable inductance comprises a plurality of metallic tubes which telescope inSide each other and which possess an expansible member within the innermost, tube so that external operation of this member can be made to bind the tubes together and prevent telescoping action. This expansible member consists preferably of two discs with bevelled edges to form a V-shaped groove in which lies a spring ring which expands and binds the tubes when the discs are forced together: In combination with the above tubes are used tubular connectors which possess clamps at their ends to grip the telescoping tubes and which can be released by rotating the body of the tube to operate a turnbuckle arid their metallic strips.. In Fig. 3 an adjustable inductance comprises telescoping tubes A2, A3, of which A2 is fixed to a support by means of brass base and stud connection and this tube is expanded by two discs A6, A8 and spring A7 which are operated by rod A13 actuated by a rotating head A10. In Fig. 10 a tubular connector comprises clamps B8 having strip metal clasps B7 which can be tightened by operation of turnbuckle B4 passing through the square.hole B2' in turning plate B2 fixed to the copper tube B1.

Abstract: 1469587 Printers INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [28 June 1974] 22875/75 Heading G4H A printer includes an array of type characters arranged in a plurality of groups presented successively in front of a print position, and means whereby, when successive print positions require use of the last group followed by the first group, printing and movement of the array along the print line are inhibited for at least one passage of a group past the print position to allow hammer recovery. As disclosed, there are two groups, one for lower case and numerals, the other for upper case and special characters, and as long as successive characters to be printed are in the same group, hammer recovery occurs during presentation of the other group, the two groups being respective halves of a multi-fingertype rotating print wheel, one character being printed per revolution, in the absence of inhibition. The wheel is driven along the print line by selective engagement with a constantlyrotating lead screw. Provision is also made for small lateral movements of the hammer.

Title: Improvements in the working of aluminium and aluminium alloys by drawing through dies
Inventor: KEEFE EDWARD JOHN
IPC: B21C3/02
Filed: 1950-09-19
Abstract: 695,029. Drawing. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Sept. 19, 1951 [Sept. 19, 1950; April 9, 1951], Nos. 23010/50 and 8203/51. Class 83 (iv). Aluminium, or alloys in which aluminium predominates, is drawn through an unlubricated die having a non-metallic working surface which is hard, tough, and of uniform texture and has a good polish. Suitable die materials are (a) synthetic resinous or plastic materials such as phenol formaldehyde, or urea formaldehyde resin or polytetrafluorethylene, (b) laminated paper or fabric bonded with synthetic resinous material, (c) fine-grained hardwoods such as ligmun-vitae, teak or boxwood, (d) a solution and dispersion of mica in glass, known under the Registered Trade Mark " Mycalex," (e) physically stable mineral materials bonded by means of synthetic resinous material, for example asbestos, talc and molybdenum disulphide bonded with a resin of the phenol formaldehyde type. The molybdenum disulphide may be in its natural form of molybdenite or in an artificial equivalent form. Graphite powder may be incorporated in intimate mixture with such mineral materials. The materials may form the whole of the die body on a lining carrying the operative surface. A die for bending strip transversely to tubular form is made of a number of plates, each formed of layers of paper bonded together with phenol formaldehyde resin, clamped together to form a die block, and the die aperture is formed by tuning. The parts subjected to greatest wear may be renewed by replacing some of the layers and remaking the aperture. The absence of lubricant enables the tube to proceed direct to the seam welder. The method is also stated to be applicable to the drawing down of tubes, for example to serve as electric cable sheathing, the clean surface promoting adhesion of a protective coating and preventing corrosion.
