Title: Method and apparatus for the manufacture of tempered glass pieces
IPC: C03B27/06
Filed: 1969-04-21
Abstract: 1,263,286. Tempering glass. VETRERIA MILANESE LUCCHINI PEREGO S.p.A. 21 April, 1969 [20 April, 1968], No. 20244/69. Heading C1M. Glass pieces having at least two plane sides 11 joined along an edge by a curved portion so that the plane surfaces are at an angle, e.g. a U- shaped channel piece, are tempered, after formation and cutting of the piece, by rapidly cooling the glass with a cooling medium, preferably gaseous (e.g. air), such that the highest cooling rate is at the concave (i.e. interior) surface of the angle 10, the lowest at the convex (exterior) surface, and the plane surfaces are cooled at an intermediate rate, so that the heat dissipation is uniform, giving a uniform stress distribution. A channel shaped piece may be tempered in the apparatus shown which comprises two sets of chambers 20, 21, each chamber being supplied with gas via header tubes 32, 33, and the gas being emitted through slots 26, 27 and 29. Slots 26 and 27 are narrower than slots 29: thus a higher cooling rate is maintained at the concave (interior) surface of the angle. A similar device, in which the slot width is narrower at the corners, is used as the complementary part 20 (Fig. 7, not shown). Glass pieces may be tempered by this method whose radius of curvature at the inside of the angle is less than the thickness of the glass.

Title: Improvements in tube bending apparatus
IPC: B21D11/07
Filed: 1950-08-16
Abstract: 674,589. Making metal fabrics. GENERAL MOTORS CORPORATION. Aug. 16, 1950 [Aug. 27, 1949], No. 20294/50. Class 83 (iv). Corrugating.-A machine for bending a plurality of tubes into serpentine shape comprises grooved rolls, between which the tubes are fed and clamped, mounted on shafts which are coupled to and uncoupled from rotators in such a manner that during the turning of a coupled rotator the rolls not aligned therewith will move orbitally about the axis of the coupled rotator. Tubing T is fed through a guide C and between grooved rolls A, Band the roll A is swung to position A<SP>1</SP> to effect bending and is then restored to position A. The tubing is again fed forward and the roll B is swung about the roll A to position B<SP>1</SP> to form a serpentine bend. Bars 59, 60 moved in opposite directions by wedge cams operated by a fluid cylinder have sockets 109, 110 in alignment with rods 111, 112 passing through grooved beading rolls A, B, and secured to a plate 120 with latch plate 123 co-operating with a latch 124 on a gear 126 rotated in alignment with rod 111 of rolls A. A shaft 131 vertically moved by cylinder 150 carries a tongue 130 engageable with a slot in a rotator 141 and in alignment with the rod 112 and rolls B and actuating the latch 124. When the rod 148 is raised by the cylinder 150 the shaft 131 is connected to the shaft 141 and the latch 124 is retracted so that the plate 122 may be rotated by the shaft 131 causing the rolls A to move orbitally about rolls B. The shaft 131 is rotated by a gear 155 meshing with a rack 158 actuated by a fluid cylinder. To allow the rolls B to move orbitally the cylinder 150 is energized to lower the shaft 131 to disconnect the shaft 141 and to latch plate 122 to gear 126. The gear 126 is then rotated from a rack operated by a cylinder to move rolls B about rolls A to the position B<SP>1</SP>, Fig. 5, to produce the second bend and then to restore the position of the rolls B. A table for supporting the tube is moved during the orbital movement of the rolls A, B, but remains stationary during restoration. The tubes are clamped by grooved jaws, Fig. 22, not shown, connected to a fluid cylinder and to a hand-actuated cam mounted on a slide actuated by another cylinder, Fig. 10, not shown, to effect the feed. A combined electrical and fluid cylinder mechanism Fig. 43, 44, not shown, comprises electromotor driven pump supplying fluid to valve actuated by cams on a shaft clutched to a driven shaft by an electromagnet to effect the tube feed, the coupling and uncoupling of the rotators and the rotation of the rotators in correct sequence.

Title: Improvements in or relating to arrangements for the automatic control of tractors and other mechanically propelled vehicles
Inventor: GILMOUR WILLIAM DUDLEY
IPC: B62D1/26
Filed: 1957-06-28
Abstract: 897,897. Steering tractors. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 18, 1958 [June 28, 1957; Aug. 21, 1957], Nos. 20412/57 and 26339/57. Class 79(5). The steering means of a tractor is associated with a non-rotatable drag which engages the lowermost part of a previously formed furrow, means being provided whereby the steering means are adjusted if the tractor deviates from a path substantially parallel to the furrow. The drag comprises a heavy chain 2 depending from the arm 3 into a furrow 1. The arm 3 is connected to a piston 4 in a hydraulic circuit controlling the tractor steering. If the tractor tends to move such that the chain leaves the furrow in one direction or the other, the arm 3 is moved causing the piston 4 to move and thus the pistons 8 and 9, from which the steering mechanism is controlled whereby the tractor is returned to its original course. Instead of the chain, a rod may be used, and the hydraulic system may be replaced by an electrical or mechanical system.

Title: Monitoring angular velocity of vehicles
IPC: B61F5/22
Filed: 1971-04-19
Abstract: 1291018 Railway vehicle undercarriages KNORR-BREMSE GmbH 19 April 1971 [26 Jan 1970] 20423/71 Addition to 1246688 Heading B7L [Also in Division G4] The parent Specification is modified in that when the angular velocity signal w or -w has fallen off a first or second control signal SL or SR is delivered when a tilt sensitive switch 32 indicates that the longitudinal plane through a sprung part and an unsprung part of the vehicle are deflected from each other in one or other direction by more than a minimum value. As described an inverter circuit 80 receives signals from both contacts of the tilt sensitive switch 32. A negative differentiating circuit 83 receives an input whenever an angular velocity signal w or -w is present. The circuits 80, 83 are connected to a bi-stable 84 the output of which is connected to AND gates 77, 78, the bi-stable being normally kept in a first state of the output of inverter 80. When the angular velocity drops to zero the output of circuit 83 switches the bi-stable if one of the contacts of switch 32 is energized. One of the gates 77 or 78 is then enabled to deliver the signal SR or SL to cause erection of the vehicle through its inclination adjusting means. This ensures that if the speed of the vehicle drops while travelling in a curve or if the vehicle whilst still tilted passes from a curved to a straight section a control signal is derived to erect the vehicle.

Title: Improvements in and relating to duplex tool boxes for metal planing and like machines
IPC: B23D1/18
Filed: 1921-08-02
Abstract: 167,476. Dusenbury, J. D. July 31, 1920, [Convention date]. Planing.-In a duplex tool-holder for a planing- machine means are provided for varying the amount of overlap of the return cut over the forward cut by adjustably inclining the plane containing the tools to the line of cut. As shown in Fig. 1, the head or clapper box 10 having clappers 12, 12a pivoted at 15 is provided with a shank 13 angularly adjustable in a sleeve 14 secured to the machine. The tools 11, 11<a> are slidably secured in slotted bolts 16 passing through apertures in the clappers and secured by nuts 21. Abutments 22 limit the pivotal movement of the clappers. By loosening a nut 23 the head 10 may be turned and fixed in any desired angular position to vary the overlap of the tools, as shown in Fig. 5. As shown in Fig. 7, which shows the adjustment for cutting rising surfaces, the tool-holder is inclined to the surface of the work to enable the inoperative cutter to clear the work. Alternatively, the clapper shown in Fig. 8 having inclined grooves 20a, 20<b> may be used for cutting rising surfaces. In this case, the tool cutting on the forward stroke is adjusted to extend below that cutting on the return stroke and the angular adjustment of the shank 13 may be used to equalise the cuts of the two tools. Figs. 10 and 11 show a device by which the tool-holder may be secured to the clapper of a machine of ordinary construction. A slide 31 on a guide 32 pivoted to the cross-feed saddle carries a pivoted clapper box 33 angularly adjustable by means of an arcuate slotted member 35 having a clapper 34 pivoted at 34<a>. The tool-holder is secured by straps 39, 40 to the clapper 34, the normal movement of which is prevented by means of an adjustable brace 44, Fig. 11, bearing at one end on the strap 40 and at the other on a spherical recess in a bracket 43 removably secured to the slide 31.

Title: Apparatus for Controlling the Supply of Electrical Power to a Load such as an Electric Motor.
IPC: H02P23/10
Filed: 1968-05-01
Abstract: 1,163,685. Control of A.C. motors. HONEYWELL Inc. 1 May, 1968 [17 May, 1967], No. 20676/68. Heading H2J. A capacitor motor 20 is supplied through a triac 26 associated with a triggering transformer 75 having a primary winding 76 connected across the current-carrying terminals of the triac which has the secondary winding 80 in its gate circuit. The transformer also has a winding 77 which is adapted to be short-circuited by a transistor 83 cyclically to disable the signal-generating operation of the transformer. Due to the inductive nature of the load, an appreciable voltage is applied to the winding 76 when the current through the triac drops to zero so that winding 80 is energized to produce a new triggering pulse immediately provided that transistor 83 has turned off so that winding 77 is not shortcircuited. If less motor power is called for, transistor 83 will still be conductive at this instant to short-circuit the winding 77 and preclude induction of any voltage in the winding 80 until the transistor 83 becomes non-conductive. The transistor 83 is controlled by a circuit comprising capacitor 62 which discharges through a transistor 63 when the potential at rectifier-terminal 37 drops to zero at the beginning of each half-cycle of the supply voltage applied to transformer 15. After a brief period, transistor 63 turns off and capacitor 62 recharges at a rate determined by the voltage across capacitor 43, which in turn depends upon the value of a temperature or other conditionresponsive resistor 57. When capacitor 62 is charged sufficiently to render transistor 55 conductive, transistors 46, 83 are turned off and the short-circuit is removed from winding 77 for the remainder of the half-cycle. A low-voltage winding 17 on the transformer 15 overcomes the voltage-drop across diodes 85, 86, and transistor 83 to render the short-circuit across winding 77 more effective. The triac may be replaced by a pair of thyristors.

Title: Improvements in or relating to the manufacture of sintered alloys
Inventor: BUSWELL RONALD WILLIAM ALFRED
IPC: C22C1/04
Filed: 1959-06-16
Abstract: A sintered alloy body comprising as major constituents chromium and nickel and/or cobalt and one or more essential minor constituents such as titanium, aluminium, zirconium, carbon or boron, is prepared from a powder mixture of the constituents in which at least one of the minor constituents is introduced in the form of a ternary master alloy with chromium and either nickel or cobalt.  The major constituents are preferably added as finely divided binary master alloys and in the case of cobalt and chromium the preferred weight range of the binary master alloy is from 40 : 60 to 60 : 40.  The ternary alloy containing up to 20% by weight of the minor constituents contains the cobalt and chromium in the same relative proportions as the binary master alloy.  The other constituents such as nickel are added as elemental powders or in the case of zirconium as the hydride and the boron may be added as an alloy with cobalt. In an example an alloy composition of 20% Cr, 16% Co, 2,35% Ti, 1,35% Al and the balance Ni was prepared from a mixture of powders of a Cr-Co master alloy, Cr-Co-Ti master alloy, Cr-Co-Al master alloy and carbonyl nickel-powder.  The mixture was pressed at 35 tons p.s.i. and sintered in vacuum at 1300 DEG C. for 20 hours.  A reducing or inert atmosphere may also be used for sintering.  Specification 887,852 is referred to.

Title: Improvements in the automatic steering of aircraft
IPC: G05D1/08
Filed: 1938-07-13
Abstract: 520,176. Controlling aircraft. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. July 13, 1938, No. 20798 [Class 135] Steering or course stabilisation of an aeroplane is effected by automatically operating the rolling controllers, such as ailerons, in accordance with the time integral of the angle of bank of the craft. To provide damping the rolling controllers may also be automatically operated in accordance with the angle of bank. Side-slip may be avoided without operation of the rudder by the inherent stability of the craft provided the rudder is suitably trimmed or it may be prevented by manual operation of the rudder or the rudder may be automatically controlled by means for detecting lateral acceleration or sideslip to adjust the rudder to reduce such lateral acceleration or side-slip. One form of apparatus comprises a gyroscopic controller as described in Specification 422,813, [Group XXXIII], modified by the addition of a viscous link 33 between the ailerons servomotor 27 and the follow-up ring 7 and by biassing said ring to a normal central position by springs 30, 31. These springs are mounted in a slidable carrier adapted to be moved by a rod 36 to steer the craft. The viscous link may comprise a piston and cylinder charged with fluid, a restricted passage connected opposite ends of the cylinder. The automatic device for minimizing side-slip is shown in Fig. 3 and comprises a servomotor 46 for actuating the rudder controlled by a valve 45 with moving valve casing follow-up. This valve is actuated by a pair of opposed diaphragms 40, 41 connected to the valve by a lever 43 and link 44 and subject to the pressures in two Pitot tubes inclined respectively to the right and left of the centre line of the craft. A pendulum may be employed in place of the diaphragms and Pitot tubes. According to the Provisional Specification a bubble side-slip deflector may be used to control the rudder.
