In the continuous casting of bars, vibrations are applied to the cast bar being withdrawn from the lower end of the mould either at the point of application of the withdrawing means or at a point between said means and the mould. A bar 4 is withdrawn intermittently from a mould 3 by pinch rolls 5 mounted in a housing 7 supported by springs 9 and vibrated vertically by vibrator units 10. If the vibrators are electrically operated, they are preferably coupled to a control unit 14 so that they are operated only when the rolls 5 are not being driven and are held by brakes 12 so that the vibrations will not be absorbed by the backlash in the roll driving mechanism. Alternatively mechanical or pneumatically-operated vibrators may be used. Horizontal vibrations could be applied to the bar by a mechanical hammer 15 between the mould and the rolls.

Title: Improvements in and relating to damping rotor oscillations in synchronous electrical machines
IPC: H02P9/10
Filed: 1961-08-16
Abstract: 967,964. Measuring electrically. BROWN, BOVERI & CO. Ltd. Aug. 16, 1961 [Aug. 18, 1960], No. 29540/61. Heading G1N. [Also in Divisions G3 and H2] The electrical angular position of a synchronous machine rotor with respect to the system voltage, i.e. load angle, is measured as a voltage by feeding the output of a pulse generator, mechanically driven from the synchronous machine, and the system voltage to a gating/inverting/ filter network. On no load, pulses 1 from the pulse generator which are aligned to correspond with the peaks of the system voltage 2 control the gating/inverting circuit to allow either the wave or the inverted wave to pass giving waveform 3, whose mean value at the filter output is zero. On load the pulses 4 are displaced in time by an amount proportional to the load angle, but the system waveform remains fixed, and after gating/ inverting waveform 5 is obtained whose mean value is now a voltage proportional to load angle. This measuring system may be used in a regulating circuit where oscillations of the rotor are damped out by varying the machine excitation (see Division H2).

[Also in Group XVI] A printing plate has a series of spaced slots at one edge to receive tabs and a series of information tabs retained in the slots, each tab serving to lock in position all the other tabs of the series which lie to one side of it, the end tab of the series being releasably 'locked in position by a resilient locking member. One edge 2 of an address printing plate 1 is folded upon itself and formed with slots 3. Information bearing tabs 4 of metal or synthetic plastic material each have a slotted tongue 5 adapted to fit in one of the slots 3 and to be retained therein by engagement of the material between the slots in the slot of each tongue. A keeper tab 6 having a slotted tongue 7 defines one end of a group of information tabs. The tab 7 is also slotted at 8 for engagement with a spring member 9 inserted in the bore formed by the folded over edge 2. The member 9 has projections 10 and 11 which engage the first two of the slots 3. The projection 11 also engages the slot 8.

Abstract: 1,094,277. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. July 13, 1965 [July 14, 1964], No. 29641/65. Heading H4K. In an exchange in which calls are established over links AVS, BVS and switching networks IRKF, MKF under the control of a common marker, the dialled number is referred to apparatus which determines whether the called party is entitled to hold the connection by means of a suitable signal which may be sent by dialling to identify an anonymous caller, and if that is the case, the marker is controlled to route the call through a call-trace link FgVS instead of through the link BVS. In the event of an incoming call from another exchange over a link CVS the re-routing is suppressed as call-tracing is not considered feasible. In another arrangement the by-path route includes switches which enable the calltrace link to serve a number of switching groups controlled by different markers.

Class 137 [Also in Group XIII] Ventilation apparatus, e.g. for a room, comprises a cooler 2 and a smaller heater 3 connected in a conventional type of refrigerant circulation system, having a reversible compressor 1, the cooler 2, of larger heat exchange capacity than the heater 3, being housed in a duct 11, through which outside air is circulated by a centrifugal fan 10, and the heater 3 being arranged in a duct 12 through which an axial flow type fan 10a circulates room air. A fixed restrictor 19, in parallel with a spring loaded pressure control device 16, controls the flow of refrigerant to the low pressure side of the circuit. A spring- loaded modulator 17 is connected in a feedback line 18 to relieve the pressure head of the compressor 1, the line 18, which becomes hot, being used to super-heat the refrigerant entering the low pressure side of the compressor. If the apparatus is used to cool air in the room, the outdoor air is passed over the cooler 2 and then into the room, flap valves, not shown, being provided in the ducts to control the flow of air. Filters, such as 14, may be arranged in the ducts

Abstract: 816,499. Steeve couplings. BURNDY CORPORATION. Sept. 24, 1957 [Oct. 17, 1956], No. 29938/57. Class 38 (1). An electrical cable connector has an inner metal ferrule joined to an outer concentric sleeve having an insulating cover, the centre conductor of a shielded cable passing through the ferrule while the shield is joined to a conductor in the space between ferrule and sleeve when the sleeve is collapsed. The centre conductor and insulation 26 of the cable 32 pass into the ferrule 16 which is joined to the sleeve 12 by the end wall 20. The braided shield 30 goes over the ferrule 16 and contacts the bared conductor 34 which may be inserted from either end. The outer sleeve 12, which may be tapered inwardly towards the end wall, is then crimped to grip the shield 30 and conductor 34. The external insulation 14 is long enough to cover the bared conductor and braiding as well as the connector and may be secured to the outer sleeve by adhesive or retained in position by internal shoulders.

Title: Tube tapering device
IPC: B21C37/18
Filed: 1966-07-04
Abstract: 1,095,230. Drawing. NORTH AMERICAN AVIATION, Inc. July 4, 1966 [July 2, 1965], No. 29983/66. Heading B3P. A tube tapering device comprises a tapering head and means for effecting relative movement between the head and the tube to be tapered to cause the tube to pass through a tapering orifice in the head, the tapering orifice being defined by at least three convergent equidistant jaws having grooves in their ends and the device also comprising means for following a template defining the required taper and for moving the jaws radially inwards and outwards in response to the contour of the template. The workpiece 13 is held between two chucks 15 and 16 mounted on a base 11. The chuck 15 rotates the tube and the chuck 16 is movable axially to maintain the tube in tension. The tapering head 19 is guided by rails 17 and is moved along the base 11 by a lead.screw 20. A three-jaw chuck 37 is bolted to a plate 63 and the scroll is actuated by a gear 95 which is connected by gears 89 and 79 to a shaft 73, which in turn is linked by gears 81, 85 and 87 to a rack 97. An hydraulic rotary valve 25 is mounted on the head 19 and a proportioner control valve 29 is mounted on an arm 33 which is fixed to the rack 95. The valve 29 has a stylus 21 which co-operates with a template 27. A pump in the base 11 supplies pressure fluid to the valves through lines 35 and 36. The chuck jaws each have a bell-mounted groove 51, which has its smallest radius (105), Fig. 7 (not shown), at the middle of the jaw. Operation.-As the head 19 moves along the rails 17 the rotary valve 25 tends to turn anticlockwise, Fig. 2, thus moving the rack 97, the arm 33, the valve 29 and the stylus 21 towards the template 27 and rotating the scroll to move the jaws 39 inwardly towards the work. When the stylus contacts the template it actuates the valve 29 so that the rotary valve 25 remains stationary. When the stylus is displaced by a change in the template contour the servo-loop constituted by the valves 25 and 29 operates to produce a corresponding movement of the jaws 39. The Specification states that the tube could be pulled through the head and/or the chuck could rotate instead of the tube.
