Title: Improvements in and relating to integrating mechanism for liquid meters
IPC: G01F15/07
Filed: 1923-07-21
Abstract: 221,613. Clayton, G., and Palatine Engineering Co., Ltd. July 21, 1923. Integrating; modifying scale of readings. - In a liquid-meter the integrating of the rate of flow with regard to time is effected on a counting train through a pivoted clock-driven member and an independently pivoted element that forms an abutting connection between the driven member and the actuating means of the counter, the position of the independent element varying with the rate of flow. As shown a float 5, Fig. 1, controlled in the known manner by a Venturi tube or other means actuates, through cams 8, 10, a recording pen 4 in contact with a chart drum 1. The cams, Figs. 2 and 3, are so constructed that the unequal movements of the float produce equal movements of the pen 4. The cam-shaft 9 carries a pinion 37 engaging a rack 36 on a slide 34 to which is pivoted an independent element or lever 31 having rollers 32 in contact with pivoted arms 14, 22. To the arm 14 is adjustably secured a slide 13a to which is pivoted a link 12 that is connected at its other end to a lever 18 provided with a cam slot 19 and pivoted at 21 to an arm 16 carrying a pawl engaging the teeth 15 of the hour wheel 11 of the clockwork mechanism. The position of the lever 18 is adjusted by means of a button 20 carried on the link 12. The teeth 15 rock the arm 14 periodically and the movement is transmitted through the independent element 31 to the arm 22 which terminates in a toothed sector 23 engaging a pinion 25 having a pawl 27 adapted to actuate a ratchet wheel 28 integral with the units wheels of the counting mechanism 30. The arm 22 is held in its adjusted position by a pawl 47 engaging a fixed rack 46 and which is freed, to permit return of the actuating parts to normal position under the action of a weight 39 secured to the wheel 25, by means of a trip bar 45 adjustably mounted on a lever 43 adapted to be rocked by a pin 42 on a catch 40 engaging the teeth of the hour wheel 11, the pawl 47 being released when a tooth 15 has passed the nose of the pawl on the lever 16.

Abstract: A calcined briquette of crystalline carbon having a sulphur and ash content each less than 1 per cent, a real specific gravity of at least 1.96, preferably 2.02-2.08, a volume resistivity of not greater than 0.008, preferably 0.00615-0.0055, ohms per c.c. and a hardness of at least 6, and preferably 7, Moh, is made by compressing and calcining a mixture of finely divided, amorphous and substantially water-free carbon having a sulphur and ash content each less than 1 per cent, and uncalcined carbonaceous binder material.  The calcined briquette may be made in a weight of 23-116 grm.  The amorphous carbon preferably comprises at least 25 per cent, preferably 50 per cent, or more of "coarse and crude oil carbon black" having a particle size of 200-600 millimicrons.  Other materials which may be used are petroleum, pitch or tar coke, retort carbon, graphite and lamp black.  The binder material may be a residual pitch of asphalt base petroleum softening at 70-127 DEG C.  Mixing may be effected at 149-204 DEG C. and the proportions may be such as to produce a powder (e.g. 80 per cent carbon and 12 per cent binder) or a paste (e.g. 77 per cent carbon and 15 per cent binder).  The volatile organic matter of the carbon black is preferably retained during the mixing. Calcining is effected in the absence of air.  It may include a period of at least 45 min. at a temperature of at least 1288 DEG C.  A number of the calcined briquettes, in an amount of 40-90 per cent, may be mixed with a mixture of carbon filler, preferably comprising crushed briquettes, and carbonaceous binder material and charged into a metal shell so that the briquettes abut one another and the inner surface of the metal shell, thus forming a Söderburg electrode.

Filed: 1960-06-01
Abstract: 909,620. Automatic voltage-control systems. LUCAS (INDUSTRIES) Ltd., JOSEPH. May 30, 1961 [June 1, 1, 1960], No. 19348/60. Class 38 (4). A control system for controlling the output of a generator is provided with means for preventing the output current of the generator from exceeding a predetermined value. The output from a generator is fed to terminals 1, 2 to feed a load, such as a battery, connected to terminals 3, 4. The generator field 13 is normally energized over a transistor 11, the base of which is connected to the collector of a further transistor 8. If the output from the generator rises above a predetermined value a Zener diode 9 becomes conductive whereupon the voltage distribution across resistors 16, 17, connected between the emitter and base of transistor 8, becomes such as to cause transistor 8 to become conductive thus causing the base of transistor 11 to be biased to reduce its conduction and to reduce the current flowing in the generator field 13. The emitters of transistors 8, 11 may be connected to terminal 1 by way of a common resistor to make the output of the generator dependent upon its speed or the upper end of potential divider 5, 6, 7 may be connected to terminal 1 to render the response of the circuit earlier than with the circuit shown in Fig. 1. The resistor 7 may be a thermistor situated adjacent the battery forming the load so that the control may be effected in dependence upon the battery temperature.

Title: Method of superimposing a foreground or image upon a background in photography
IPC: G03B15/08
Filed: 1929-06-24
Abstract: 333,010. Walker, W. D. June 24, 1929. Drawings to Specification. Composite photographs; catatype processes.- Composite photographs, especially kinematograph films, are produced by photographing a transparent film on the background illuminated from the rear, in superposition behind a film of the foreground illuminated from in front, in which the image is opaque to but reflective of light. The parts surrounding the images on the foreground film are transparent, the actors &c. being photographed in front of a white screen to produce a positive or a black screen when a negative is required. To render the images on the foreground film opaque, the emulsion side is coated with a mixture containing a colloid such as gelatin, a chromate or bichromate, e.g. ammonium bichromate, and a white pigment, e.g. Chinese white. In contact with the silver of the image the colloid becomes insoluble, binding the pigment, the mixture being then washed off the silver free parts of the film. The bichromate may be applied first and then a mixture of colloid and pigment. For television motion pictures a dark pigment, e.g. ultramarine, is used.

Abstract: 493,966. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. July 14, 1937, No. 19540. Convention date, Sept. 2, 1936. [Classes 40 (iii) and 40 (v)] In a short-wave oscillator whose frequency is stabilized. by means of Lecher wires or coaxial cylinders, instability due to the reactance inherent in the valve is avoided by coupling the valve to a quarter-wavelength loop by means of a network whose electrical length is half a wavelength ; and damping of the loop through dissipation in the valve and its leads may be minimized by connecting the loop at points near its short-circuited end. The interelectrode capacity 3 resonates with a limped inductance 2 and capacity 1 at the operating frequency, so that the network 1, 2, 3 behaves like a half-wavelength line. The quarterwavelength Lecher - wire loop 4 therefore behaves as if it were connected to a valve with negligible interelectrode capacity and leads of zero impedance. Further, detuning of the resonant line 4, which occurs as a result of energy-dissipation in the valve when the latter is connected to the open end of the line, as shown in Fig. 5, may be obviated by connecting the valve to points near the short-circuited end of the line, which may be a coaxial cylinder, as illustrated in Fig. 6 (not shown). The output circuit 7 is tuned approximately to the operating frequency.

Abstract: In contact processes involving a cycle of operations effected in presence of the same contact mass which contains a component favourable to one operation and unfavourable to another operation, the said component is alternately deactivated for the operation for which it is unfavourable and restored to activity for the p operation for which it is favourable.

To promote the regeneration a compound of iron, manganese, nickel, copper, or cobalt is incorporated in the contact mass.  To avoid an adverse effect on the cracking operation this compound is rendered inactive by treatment with hydrogen sulphide or an organic sulphide, and it is restored to activity by the regenerating gas or by a preliminary treatment with steam or hydrogen.
