Title: Improvements in or relating to the animation of articulated figures
IPC: A63H7/00
Filed: 1946-11-06
Abstract: 621,905. Articulated figures. PELHAM, R. H. Nov. 6,1946, No. 33016. [Class 132 (iii)] An animated articulated figure comprises a loosely jointed body portion a, b Fig. 4 with loosely jointed articulated legs and arms through which cords 8 are passed and is mounted on a base 11, the cords of the individual limbs being attached directly to keys or levers 9 rockingly supported springs 12 Fig. 3 acting on said levers to tension the said cords.. The springs may be on either side of the lever fulcrum, so that the tension may be relaxed causing the figure to collapse by upward or downward pressure whichever is appropriate. Squeakers 7 or other sound producing devices may be placed between the levers and the base platform, and if these are provided with internal compression springs the tension springs 12 may be omitted. The head may be attached to the body by a flexible coil or leaf.spring. The levers , may, be replaced by rotatable pegs 9 (Fig. 5) mounted freely in the base. As shown (Fig. 5) each arm is controlled by two cords passing through separate bores in the articulated parts (Fig. 7) one end being attached to the terminal hands and the other wound several times round grooves or small pulleys 10 on the pegs. The cords may be continuous or separated, and they are wound round the pegs a sufficient number of times for the tightening of one cord when the peg is 'rotated to balance the slackening of the other. This enables lateral movements to be made. Stop collars 13 limit the outward movement of the pegs. Modifications for use on miniature stages are described in which the pegs are on the same side of the base and in which a number of figures can be operated by the same pegs. If desired the levers may be suitably weighted instead of spring controlled. The Provisional Specification describes in addition a modification in which the feet of the figure may be shuffled backwards and forwards. The base is provided with slots instead of holes through which the cords 8 pass, and the levers are so mounted as to be capable of sideways as well as upward and downward movement.

Filed: 1920-11-23
Abstract: 178,878. Bell, A., Laundy, P. H., and Scarlett, A. E. Nov. 23, 1920. Concentric straight-tube apparatus.- In apparatus for cooling the hot oil from the jacket of an electric transformer by means of water, and for other purposes, of the kind having concentric tubes disposed between tube-plates, the inner and outer tubes are so mounted as to allow of expansion with respect to each other and with respect to the casing. Tubes b in a casing a are secured to tube-plates c, d, and are surrounded by open-ended tubes e supported by cross plates f, g. The plates d, f, and g are free to slide in the casing. The oil or other fluid to be cooled enters through an opening p at the top of the space between the tube plate c and the cross plate f, and is directed forwards and backwards by partitions n, o downwardly through the annular spaces between tha tubes. The outer tubes may be formed with helical grooves. Water or other cooling-medium entering through the connection j at the bottom of the casing flows forwards and backwards through the inner tubes to the outlet k. The oil is allowed to flow into the space between the cross plates, thus equalizing the pressure on the opposite sides of the plates. In a modification, the front cross-plate is dispensed with, and horizontal plates extending between the front tube-plate and the rear-cross plate are provided to direct the oil in a forward and backward course.

Title: Process and apparatus for electrical resistance welding of sheet edges
Inventor: TAPPOLET KARL HEINRICH
IPC: B23K11/087
Filed: 1969-07-02
Abstract: 1,274,022. Welding by pressure. TAGERS G.m.b.H. 2 July, 1969 [5 July, 1968], No. 33387/69. Heading B3R. In resistance welding the edges of a metal sheet or sheets marginal portions are bent over to form an acute angle with the adjacent portion of the sheet or sheets, the bent over portions are hooked together and are pulled by forces applied to the sheet or sheets until the portions extend substantially at right angles to the adjacent portions of the sheet or sheets and welding electrodes are pressed upon the edge portions in the direction in which they extend and current is passed between the electrodes. A metal sheet has its ends 1, 2, Fig. 1, bent through about 110 degrees and these ends are interlocked and pulled by forces Z to bend the ends to a position substantially normal to the remainder of the sheet, current and pressure then being supplied by elongated electrodes pressed against the sheets in the directions of the bent portions. To produce a car body an apparatus is used comprising a cylindrical mandrel 27, Fig. 3, having opposite movable jaws 28, a feed means 29 for pushing a flat sheet with bent ends over the mandrel, two curved bending jaws 33 on a pivot axis 32, an upper elongated welding electrode 25 in the mandrel and a lower elongated movable electrode 26. The sheet with bent ends as in Fig. 1 is pushed over the mandrel, the bent ends being guided in rails 31, the two jaws are swung to bend the sheet and the bent ends are interlocked. The electrode 26 is then moved upwardly rapidly at first and then more slowly to avoid impact with the bent ends and to apply a light pressure against the ends. The jaws 28 are then moved apart by means of wedges on a central rod 35 into the position shown in Fig. 6 to straighten the bent ends and then the lower electrode 26 is pressed harder against the bent ends and current is supplied to effect welding.

Abstract: 1,196,546. Positive clutches. HITACHI SEIKI K.K. 15 July, 1968, No. 33598/68. Heading F2C. [Also in Division B3] In a positive clutch, the spacing of pins 3 differs from the spacing of apertures 4 in relatively rotatable coupling members A, B1, B2 such that, when the pins are moved towards the apertures and two of the pins wholly engage in corresponding apertures, Fig. 4 (not shown), then the pins on either side of the wholly engaged pins partially engage in corresponding apertures, Fig. 6, and backlash between the coupling member A and one or other of the coupling members B1, B2 is eliminated. When the coupling members A, B1 or A, B2 are so positioned that no pin completely engages in an aperture, Fig. 5 (not shown), there is still partial engagement by a number of the pins and apertures, Fig. 7, and coupling without backlash is again provided. Fig. 1 represents the use of the clutch in a machine, tool having a carriage (not shown) which may be advanced by a screw shaft 5 rotated, via the clutch and two-speed gear 6-9, actuated by a pulse motor 11. The speed is selected by fluid pressure applied at inlets 13 or 14, causing the pins 3 to move toward coupling member B1 or B2 respectively. The pins having been extended, fluid pressure applied to an inlet 16 causes the pins to be secured by lateral pressure. Mechanical or electromagnetic means may be used for operating the pins 3. In a further application, Fig. 8, a coupling body A is secured to a carriage 2 by bolts 7, the post 2 sliding on a lathe bed 6 provided with a rack B. When a member 5 vertically slidable in the body A is pushed upwardly a number of the pins 3 are spring urged into engagement with some of the spaces between the rack teeth and the tool post 2 is positively located relative to the rack B and the bed 6.

Title: Improvements in or relating to froth flotation concentration processes
IPC: B03D1/14
Filed: 1933-11-30
Abstract: 434,352. Concentrating ores. TAPLIN, T. J., 6, Walpole Gardens, Strawberry Hill, Middlesex. Nov. 30, 1933, Nos. 33668/33 and 13294/34. [Class 82 (ii)] In order to ensure good contact between the air bubbles and the mineral particles in froth flotation concentration a vibratory movement is imparted to the pulp in addition to the normal movement produced in the aeration by agitation or by the direct introduction of air, the vibratory movement being produced by imparting vibration to an impermeable surface in contact with the pulp on one side only. The vibration may be of sonic or supersonic frequency and is preferably applied in a direction transverse to the general movement of the bubbles in the pulp. In the form shown in Fig. 1, air is introduced through a pipe 15 and a porous false bottom 14 to ore pulp in a cell 11 having an overflow lip 13 for the froth. An aperture 19 in one wall of the cell is closed by a rubber diaphragm 20 which is connected by washers and clamping nuts to a rod 24 united by a coupling 38 to a push rod 33 held by a spring 36 against a cam 30 which is rotated at a speed sufficient to vibrate the diaphragm 20 at a frequency of about 300 cycles per second. Alternatively the diaphragm 20 may be vibrated by an intermittently energized electromagnet. Fig. 3 shows a pneumatic flotation cell in which the vibratory movement of the pulp is effected by imparting vibrations to a liquid in a rubber bag 44 on the end of a pipe 45 depending into the pulp from above. The liquid in the bag is deaerated and a pump may be employed or the height of the pipe 45 may be made sufficient to maintain the liquid under superatmospheric pressure to prevent cavitation. In the form shown in Fig. 4, two pneumatic cells 50, 51 are located side by side with a compartment 52 between them, the partitions 53, 54 being thin enough to transmit vibrations. The compartment 52 is partly filled with water and a flexible diaphragm 57 is vibrated by cam mechanism or by means of an electromagnet and causes the water to vibrate, the vibrations being transmitted to the pulp in the cells 50, 51 through the partitions 53, 54. The compartment 52 may be closed at the top so that the water may be maintained under superatmospheric pressure. To prevent cavitation the vibrations may be periodically interrupted, for example when using an electromagnetic vibrator a relay device may be provided which interrupts the vibrator when the power required to effect the vibrations falls owing to cavitation. U.S.A. Specification 1,910,386 is referred to.

Title: Picture control apparatus for a television receiver
IPC: H04N5/16
Filed: 1964-08-18
Abstract: 1,057,474. Controlling television picture signals. HAZELTINE CORPORATION. Aug. 18, 1964 [Sept. 18, 1963], No. 33689/64. Heading H3Q. A television receiver includes a keyed A.G.C. circuit which is responsive to the blanking level of the video signal and develops a signal jointly representative of variations in received signal intensity and of variations in average scene brightness, whereby the black level is stabilized and the cathode-ray tube beam current is limited on scenes of high average brightness. In Fig. 1, the video amplifier 13 is connected to the cathode of the picture tube via a control circuit 14 in which the A.C. component of the signal is passed on in full via capacitor 24 while the D.C. component is attenuated by a potential divider 25, 26. The variation in black level so produced is compensated by a keyed A.G.C. circuit 27 fed with positive flyback pulses from the line output circuit at 28. The resulting signal is integrated by capacitor 33 and used to control the gain of the earlier stages of the receiver. The net effect is that the black level is stabilized while variations in the beam current (and hence the mean brightness) are reduced. In an alternative arrangement (Fig. 3, not Shown), the resistor 26 is omitted so that the cathode-ray beam current flows through resistor 25 and there is no attenuation of the D.C. component. The A.G.C. signal is now dependent directly on the beam current and acts to reduce mean variations thereof as well as stabilizing the black level. In another version (Fig. 5, not shown), the resistor 25 is replaced by a diode (see Specification 1,008,010) so that the D.C. component is attenuated only for scenes of high average brightness. The circuit of Fig. 6 (not shown) can be used when the signal is applied to the grid of the cathode-ray tube. The video signal is inverted in a second amplifying stage 70 and A.C. coupled to the tube, D.C. restoration being effected by a diode 74 to which flyback pulses are applied through winding 75. The A.G.C. circuit 27 of Fig. 1 is supplemented by a transistor amplifier 72 which passes on the D.C. component of the video signal via line 85, the A.C. component being shunted to earth by capacitor 81. For use with a positive modulation system the circuit of Fig. 1 can be modified (Fig. 8, not shown) by feeding the signal on to the tube grid instead of the cathode, and shifting the capacitor 24 to be across the lower half of resistor 26. This results in attenuation of the A.C. component to a greater extent than the D.C., in contrast to the arrangement of Fig. 1.
