Title: Improvements in or relating to the Sealing of Petrol Tins and other Stoppered Vessels or Containers.
Inventor: JOHNSON HARRY WILDAY
IPC: B21D51/42
Filed: 1916-03-28
Abstract: 104,760. Johnson, H. W. March 28, 1916. Sealing petrol tins &c.-Petrol tins and other stoppered vessels or containers are. sealed by metal or like seals 9, Fig. 8, passing over the stopper, the ends of the seal being forced into an undercut recess or groove 6, of channel or U shape in crosssection, formed in an overhanging flange or rim 5 on the neck of the container. A device for applying a seal comprises a hollow cylindrical fitting 10, Fig. 3, containing a spring-pressed plunger 11 and carrying two levers 18, which operate sliding members 14 on the open end of the cylinder 10. Fittings 15 at the inner edges of the members 14 have knife-edged projections 21 adapted to enter the recess 6 in the rim of the petrol tin, &c. When the handles 20 of the levers 18 are pressed inwa.rdly, the members 14 are retracted against the action of springs 16. The plunger 11 is formed with recesses 22 to engage the projections 2 on the stopper, and is embossed or inscribed with any matter it is desired to imprint on the seal. When sealing is effected, projections 24 on the plunged 11 lie at the wide upper ends of slots 25 in the casing 10, so that the fitting can be rotated relatively to the plunger and the surplus ends of the seal cut off. On removing the fitting from the stopper, the plunger 11 is turned backwards by the projections 24 engaging the inclined sides of the slots 25. Fig. 11 shows the device 10 carried by a weighted lever 27 pivoted to a stand 26. The plunger 11 is forced down by a rod 32, which passes through the screwed top 28 of the fitting 10, and is acted upon by a lever 33 pivoted to the lever 27. The tins are fed down an incline 34 so as to be presented to the sealing-device with the top of the stopper horizontal. Fig. 12 shows a sealing-device in which the material 40 from which the seals are made is fed automatically from a reel 39 carried by a bracket 35 on the casing 10. The upper feed-roller 37 is geared to a wheel 41 connected to a free wheel 42 operated by a spring- pressed toothed quadrant 45, which has an extension 46 lying in the path of one of the plunger projections 24. On removing a sealed tin from the sealing-device, a pivoted lever 48, which carries a piece 50 to bear against the neck of the tin, is rocked by a spring 51, whereupon the quadrant 45 is drawn upwardly by its spring 47 and the strip 40 fed forward ready for the next sealing operation. The invention is applicable to vessels formed of glass, earthenware, &c.

Abstract: 1,080,591. Automatic speed control for zoom lenses. RANK PRECISION INDUSTRIES Ltd. [trading as RANK ORGANISATION RANK TAYLOR HOBSON DIVISION]. Jan. 30, 1964 [Feb. 5, 1963], No.4640/63. Headings G2J and G3R. [Also in Division H2] A television camera has a zoom objective comprising movable members associated with drive member B5 which is coupled to motor E. A zoom control element is constituted by a hand lever which is spring-biased to a central zero position and adjusts potentiometer D. The output from this potentiometer is opposed by the voltage of tachometer generator E1 for application to amplifier F which supplies the motor. To prevent impact with an end stop, over-riding control is provided by potentiometer G whose contact is coupled to the member B5 and provides feedback which reduces the motor speed as the member B5 approaches either of its limiting positions. Movement of the member B5 from an end-position is not impeded by the potentiometer G. The potentiometer G may have low-resistance end-portions or spaced parts separated by insulation. Alternatively, a slip device is employed in the drive between member B5 and contact G1 so that the contact is moved over the end portions of the range of movement. In another arrangement, the motor E drives a front member of the zoom objective which is movable for focusing by a hand-wheel coupled to tachometer generator K. As the driven member approaches a limit position, contact G1 approaches the upper end, for example, of the winding of potentiometer G. Current from generator K then passes to earth through Zener diode L1 to reduce the voltage applied to the servomotor. If the handwheel is now turned in the opposite direction, the low impedance path to earth is blocked so that the servomotor operates at full speed. A pair of Zener diodes M may clip the voltage output of the generator K. The tachometer generator E1 may be replaced by a bridge circuit for detecting the back-electromotive force of the motor. In another embodiment, the hand-wheel acts through a variable speed gear to drive the objective movable for zooming, the gear comprising two oppositely directed rotatable cones with an intermediate part slidable between them. Cams are brought into action to drive a pinion gear and shift the intermediate part so that the member B5 is driven at a minimum speed. The drive may be duplicated for reversible operation of the member B5. When a hydraulic transmission is employed, the feedback means may act to vary the angle of a swashplate at the end portions of a range of travel.

Title: Improvements in supports for lids of boxes and the like
IPC: E05C17/34
Filed: 1927-02-18
Abstract: 286,439. Gramophone Co., Ltd., and Buckle, H. L. T. Feb. 18, 1927. Stays.-The hinged lid of a gramaphone cabinet and the like is held in an open position by jointed stay-arms 1, 2 connected to attachment brackets 16, the joint connecting these arms comprising balls 7 which are seated in apertures or depressions in the arm 2 and project through holes in the other arm 1 so as to be engaged by spring arms 9 of a disc 11. The' members 1, 2, 11 and washers 13, 14 are held together by a pivot pin 5. The springs 9 are formed by working a pair of S-shaped cuts in the thin disc 11 of spring steel, this disc being then pinned to the arm 1 at 12 so that these members move together. When a light pressure is applied to close the lid the relative movement of the jointed arms 1, 2 as they fold causes the balls 7 to ride out of the holes in the arm 2 and the springs 9 to be deformed as shown in Fig. 7, the arrangement providing a brake for the closing movement of the lid.

IPC: G01R35/04
Filed: 1950-02-23
Abstract: 695,364. Supply meters; power measurements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 13, 1951 [Feb. 23, 1950], No. 4719/50. Class 37. In order to measure volt amperes or voltampere-hours, a watt meter or watt hour meter has both current and voltage coils energized in accordance with either the voltage or current of the circuit. The meter M has its voltage coil 3 connected across the mains 1, 2 and its current coil 4 connected across the mains 1, 2 in series with an operating coil 5 of a torque balance relay TR, a ballast resistor 6, and the contact arm 7 of a potentiometer 8 connected across the mains 1, 2. The relay TR includes a second operating coil 9 energized in accordance with the current in the main 2 through a current transformer 10. The relay TR is of the induction type and is driven in opposite directions by the coils 5, 9 so that its moving contact 11 engages one of two contacts 16, 17 according as the ampere turns of the coil 5 are greater or less than those of the coil 9. The contact arm 7 is driven through a reduction gear 12 from a reversible motor RM having a winding 13 connected across the mains 1, 2 and a winding 14 connected between the moving contact 11 and the centre tapping of a resistor 15 connected across the mains 1, 2. The motor RM drives the contact arm 7 in one direction or the other according to the relative senses of the currents in the coils 13, 14, which depends upon which of the contacts 16, 17 is engaged by the moving contact 11. The potentiometer 8 is thus adjusted so that the current in the coil 4 is maintained in proportion to that in the mains 1, 2. Since the currents in both coils 3, 4 are derived from the mains voltage they have a predetermined phase relationship which is unaffected by the phase relation between the current and voltage in the mains. This phase relationship may be modified by a resistance or reactance so that the meter M may operate at any desired power factor. Alternatively the current coil 4 may be energized directly in accordance with the current in the circuit by means of a current transformer, whilst the voltage coil 3 is supplied from the same transformer under control of a motor operated rheostat controlled by a torque balance relay operating in accordance with the voltage of the circuit. Modifications are described for use in balanced or unbalanced polyphase systems. Specification 670,536 is referred to.
