Title: Improvements in or relating to heating means for type casting or compositing machines
IPC: B41B11/76
Filed: 1928-03-16
Abstract: 306,882. Bader, T. Feb. 27, 1928, [Convention date]. Metal-pots.-The metal-pots of type-bar-making, type-casting, and like machines are adapted to be heated either simultaneously or alternatively by gas and electricity, without any alteration or adjustment of the apparatus, the change from one heating power to the other being effected automatically. The failure of either heating power is caused to bring the other into action under the control of an automatic temperature-regulating device. The gas heating means comprises burners 1, 2, Fig. 9, for the pot and the mouthpiece respectively, the flames being drawn through draught passages 3, 4, 6, 8, Figs. 3 and 4. Replaceable electric heating-elements 9, 10, 11 rest in arcuate pockets in the interior of the pot, and a tubular heating-element 12 is arranged in the passage 8, so as not to interfere with the draught. A flexible heating-element 13 is mounted on the casing-mouth passage, to which it is adapted by rows of screws 13, the element as a whole being adjusted by means of a screw 17. The temperature-controlling means includes a mercury-filled spiral 20, Fig. 8, connected to the metal-pot, and acting on a rod 21, which carries an adjustable nut 23. The nut 23 acts through a lever 25 on a tipping switch 28, consisting of a glass tube, rotatable about a pivot 29, and having contacts 30, 31 which, when the tube is horizontal, are connected by a strip of mercury insidei the tube. The rod 21 also acts on an indicating-finger 34, moving over a temperature scale 35, and adapted to strike contacts 36, 37 located at opposite ends of the scale, whereby the electrical power is switched on or off, and one or other of two signal lamps 38, 39 is lighted, or other signals are actuated. The electrical heating means are connected to the mains through a hand-operated switch 41. A second switch 42 is adapted to be actuated automatically by a clockwork 43, or by electromagnets 44, 45 when, on the attainment of the maximum or minimum temperature, the finger 34 strikes one of the contacts 36, 37. The current passes from a line 47 through a variable resistance 49 to the mouthpiece heating-element 13, and back by a line 46. A branch 48 from the line 47 leads through the tipping switch 28 to the other heating-elements 9, 10, 11, which are thereby cut out, when the temperature rises, before the element 13 is effected. The resistance 49 may have a number of steps, and may itself serve as a. heating element. The gas supply is under the control of a clock 58, and also of a valve 59, which is operated by a clockwork 67, and controlled by an escapement 60. Adjustable stops 64, 65 connected to the escapement are adapted to be displaced by a finger 66 on the rod 21, so that a half-rotation is given to the valve 59, as the temperature rises and falls. The clocks 43, 58 affect an automatic switching over at predetermined times, in accordance with the more favourable tariff.

Abstract: 1,242,923. Drive device for toy. J. A. VIDAL. 14 Feb., 1969 [20 Feb., 1968], No. 8194/69. Heading A6S. A drive device for a toy has a spindle 7 on which is mounted one end of a spring 11 for frictional attachment thereto when the spring is wound up or tensioned, the spring, when in use being anchored to the toy at its other end, the spindle also being attached to a braking device which is in the form of a cylindrical casing 1 filled with a viscous fluid and containing a vane device 10 on a spindle 8 rotatable in the casing but, in use, non rotatably mounted in the toy, the cyindrical casing itself acting as a rolling surface and traction means. A regular drive speed is thus produced. The inner end of the spring 11 terminates in a loop 12 which when the spring is tensioned grips flat faces 13 formed on a boss 5 of the spindle 7. If the spring is untensioned, however, and then is wound in the wrong direction the loop will slide loosely about about the spindle, thus avoiding damage to the spring. The toy may rest on two rounded pins 23 in addition to the casing 1.

Filed: 1971-04-02
Abstract: 1390357 Television flight simulator REDIFON Ltd 28 March 1972 [2 April 1971] 8509/71 Heading H4F In a colour television display for a flight simulator, the detail of the image of the ground or sky in selected bands of the display can be progressively replaced by featureless areas to represent ground fog and/or low cloud and these bands varied in position and slope in accordance with flight computers readings of aircraft pitch and/or roll. In the display of Fig. 1, the simulated aircraft has a roll to the right of # and pitch upwards (horizontal line H-H<SP>1</SP> below centre O). The area CDEG is at maximum clarity, the area ABLJ is at minimum clarity or clouded; and the area EGLJ varies in clarity from maximum (line EG) tominimum (line JL). If the amplitude Z of a cloud video signal to be progressively substituted for the ground/sky video signal, varies in the Y (frame) direction according to M = slope of brightness change, y 1  = co-ordinate of zero amplitude and a simulated roll shift of # occurs, then the band should shift to a position defined by and the circuit of Fig. 3 is required to produce such an analogue variation on the green (68), red (67) and blue (70) video signals of the normal input. The flight computer provides signals representing Sin # and Cos # from 1 and feeds them to integrators 6 and 8 together with x and y deflection signals. The resulting x Sin # and y Cos # signals are combined with Sin # and Cos # signals in subtracting amplifier 12, via weighting resistors 11. The instructor sets, in a console 30, the relative visibilities of cloud and ground, the colour of cloud and/or mist at day, dusk and night andthe thickness of the cloud and/or mist. Signals proportional to these factors are combined at 66, 67 with computer derived pitch and aircraft height data to give position data for the cloud and/or mist and are also fed via red, blue, green colour gates 43-48, to variable cloud/mist amplifiers 18, 20, 22 for control by function (A). The ground/sky tricolour signals are similarly fed to variable amplifiers 17, 19, 21, for inverse control by function (A), with corresponding colour cloud/fog and ground/sky signals being combined at 23, 24, 25.
