Title: Improvements in or relating to indexing tables and the like
IPC: B23Q16/06
Filed: 1965-03-10
Abstract: 1,078,652. Indexing table. TRANSFER TOOLS Ltd., and D. R. PATERSON. March 9, 1966 [March 10,1965], No. 10245/65. Heading B3B. [Also in Divisions E2 and F2] An indexing table assembly has an indexible table (10) (Fig. 2, not shown) and a two-arm latching lever that comprises a straight arm 35 carrying a roller 36 and a D-shaped arm 38 that has a notch 34, for engaging projections 30 on the indexible table (10) for locking the table at the indexed position. Rollers 57 are positioned on each side of the notch 34 and are spaced apart to a distance slightly less than the diameter of the projection 30 to ensure interference contact therewith. The rollers engage the projection 30 until a line joining their centres passes behind the centre of the projection to make the latch self-locking. The latching lever is spring-loaded into the engaged position by springs 45 (Fig. 1, not shown) acting through a toggle linkage (42), (43). The latching lever is released before indexing by a cam 29 connected to the electric motor drive of the indexible table (10). The drive to the table (10) includes a Geneva mechanism 15 for indexing the table so that the projections 30 align with the latching lever. The D-shaped part of the latching lever includes an opening 61 and a slit 62 leading therefrom to enable an adjusting device 65, 64 to vary the distance between the rollers 57. Electric switches (74), (75) (Fig. 1, not shown) control indicators showing that the latching lever is engaged and that the table has reached its indexed position. The catching device may be used on rectilinearly movable tables or supports movable from one to another of several fixed positions. The latching lever pivots on a pin (47) (Fig. 3, not shown) having oppositely tapered portions (48), (49) and resilient pads (55) urge the split internally tapered inner bearing parts (54) of the pivot bearing (51) along the tapered portions (48), (49) to take up wear and prevent play from developing in the bearing.

Title: Improvements in or relating to Switched Voltage Regulator Arrangements
IPC: H02M3/156
Filed: 1967-03-03
Abstract: 1,172,544. Automatic voltage control. MARCONI CO. Ltd. March 3, 1967 [March 7, 1966], No.10275/67. Heading G3R. A voltage regulator of the type in which a transistor 2 is switched on and off by a comparator control circuit comprising members 3, 4, 5, 10, power being supplied by storage members 7, 8, 7<SP>1</SP> , 8<SP>1</SP>, when transistor 2 is off, also includes a protective arrangement comprising members 15-- 23 which operates when the current flowing through resistor 19 exceeds a predetermined value to control the comparator control so that the output current is regulated to a substantially constant value by reducing the mark/space ratio of the transistor 2 to a value determined by the time constant provided by members 20, 22. In a typical cycle of operation, excess current causes members 15, 21 to conduct and transistor 3 is switched well into conduction to cut off transistor 2, which causes the immediate cut off of transistor 15 and the cut off of transistor 3 after a time delay determined by members 20, 22. Members 24, 25, 26 cause transistor 3 to operate as a linear amplifier with a high emitter resistor under overload or short circuit conditions, thus limiting the base current of transistor 3 and isolating the Zener diode 5. Members 27, 28 produce voltage and thermal balance in the comparator amplifier and isolate the resistor 20 from the bias network of transistor 3. Members 10, 11, 12 control the rise of charging current for the capacitor 8 when first switching on the regulator. The integrating circuit 13, 14 controls the rate of rise in the reference voltage during the switch-on transient period, causing switching to commence early.

Title: Improvements in or relating to motor road vehicles
IPC: B60G17/027
Filed: 1919-04-25
Abstract: 143,006. Mole, L. E. de. April 25, 1919. Springs, arrangement of.-In a vehicle having at least four pairs of road wheels, the supporting- spring for each wheel is subjected to a stress of the same order as that due to the normal load, so that the springs do not come into action unless the wheel is raised 'by a projection on the road, while the wheels are held up so that they cannot follow road depressions. A dash-pot prevents too rapid lowering of the axle after it has been raised. Between each end of the axle 3, Fig. 2, and the frame is placed an elliptic or other bearing-spring, the expansion of which is limited by the bolts 6 carrying a dash-pot, shown in section in Fig. 3. The dash-pot consists of a piston 7<a> moving in a cylinder 7 contained in an outer cylinder 16, the inner cylinder 7 and the annular space between the two cylinders being connected by relief-holes 24 and a valve 12, so that the piston can move upward freely, but can only descend slowly. The piston 7<a> is connected to a plate 17 which is guided vertically on the bolts 6 and also carries bolts 18 connected at their upper ends by the plate 20. Springs 19 around the bolts 18 bear downwards against a plate 21 secured to the axle 3. When the axle 3 is raised by a projection on the ground it moves upward by means of the plate 21, the piston 7<a>, the plate 17, and the bolts 18 and associated parts, until the upper ends of the bolts bear against the hanger 22, after which the axle moves upwards alone, the springs 19 being compressed. The return of the axle to its original position is retarded during the latter part of its movement by the dash-pot.

Filed: 1930-04-02
Abstract: 351,117. Regulating. ROYCE, SIR F. H., Nightingale Road, Derby. April 2, 1930, No. 10442. [Classes 7 (iii), 7 (iv), and 7 (vi).] In an aircraft engine having an aneroid device controlling the throttle valve, the timing of the ignition, or the petrol-metering device, a hand control is combined with the automatic control by means of a floating lever connected at one end to the pilot's control lever, at the other end to the aneroid device, preferably through a relay, and at an intermediate point to the part to be adjusted. The Figure shows the lever h connected by a rod h4 to the hand-control, by a rod h<1> to a relay piston d controlled by a valve b<3> and aneroid b, and by a rod h<2> to the throttle valve a<4>. The pressure in the outlet a<2> of the blower a<3> is led by a pipe e to the casing b<1> of the aneroid, and is admitted by the valve b<3> to one or other side of the piston d, the pressure at the inlet a<1> of the blower being admitted by a pipe e<1> and the valve b<3> to the other side of the piston, which is thus operated in the required direction. Instead of using the blower pressure to actuate the relay, other liquid or fluid pressure may be used, the pressures in the lubricating or water-cooling systems being mentioned in the Provisional Specification. Means for protecting the aneroid device from damage due to back-fires or excessive vacuum may be used as described in Specification 346,503. The relay devices described in Specifications 344,041 and 349,209 may also be employed.

Abstract: 1,045,556. Stretching. TRUNINGER A.G. March 16, 1964 [March 19, 1963], No. 11013/64. Heading B3E. A machine for stretching and straightening hollow steel-section members includes vices for gripping the two ends of the member, one vice being adapted to be moved towards and away from the other vice by means of a carriage, and props, provided at short intervals between the vices, which can be raised by a common control element into respective operative positions for constraining the member into arcuate form while it is being stretched. A tube Ro of rectangular section is gripped at one end by a gripper 4 pivoted on a cross-bearer 3 on a machine bed 2 and at its other end by a gripper 5, Fig. 5 (not shown), pivoted on a carriage moved away from the gripper 4, to stretch the tube, by hydraulic cylinder means 6. Hydraulic cylinders 14 spaced along the bed 2 between the grippers 4, 5 move thrust members 16 so that the tube Ro is lifted to an arcuate position. The tube Ro is stretched after it has been lifted by the members 16. This compensates for uneven stretching of the tube so that when the tube, thus stretched, is released from the grippers 4, 5 it assumes a straight, uncurved state. The grippers 4, 5 are rotatable synchronously to bring the tube for stretching into the correct plane. The members 16 may be positioned by screw means driven from a horizontal shaft, different transmission ratios being provided for the screws of each member 16 or, with a single transmission ratio, the screws have differing pitches.
