Title: Film frame counter
IPC: H03K5/26
Filed: 1972-12-12
Abstract: 1404160 Cinematography SINGER CO 12 Dec 1972 [21 Dec 1971] 57269/72 Heading G2E [Also in Division G4] A film frame counter uses two sensing devices A, B which sense simultaneously two longitudinally separated film perforations these devices being separated such that when one senses the upper half of a film perforation the other senses the lower half of another perforation. A logic circuit is provided, Fig. 2, which receives the outputs of the sensing devices and only when predetermined sequences of outputs are received will the circuit register a forward or reverse movement of the film. For use with the circuit shown the sensing devices comprise a bundle of light transmitting fibres surrounding a single light receiving fibre. Two signal levels at the output of the device are possible, one corresponding to light being reflected back from the film and the other when no reflected light is sensed, a perforation then being aligned with the device. The devices' outputs are amplified and then inverted at 35. The outputs of the devices pass along lines 39, 49. When the sensing devices detect a perforation this corresponds to a logical 1 (columns A, B in table) and a logical "0" when no perforation is detected. The table presents the predetermined forward and reverse sequences to be received by the logic circuit. Identical latches 45, 51, 55, 59 are initially switched to produce a "0" output. When the input C at each latch is changed from "0" to "1" the D input is outputted at Q. When two "1" inputs are received at the AND gates 47, 57 then a forward or reverse count respectively is registered by counter 52. Two "1" inputs to one of the gates 47, 57 are only possible by completion of the sequences shown in the table. The values registered by the counter 62 are divided by the number of perforations per film frame. At the completion of each sequence the two logical "1"'s on lines 39, 49 are forwarded by AND gate 61 to multivibrators 63, 65 which apply or pulse to each latch to return it to its initial position.

Abstract: 1361192 Voltage regulators JOSEPH LUCAS (INDUSTRIES) Ltd 16 Nov 1971 [11 Dec 1970] 58865/70 Heading G3R A transistorized voltage regulator for charging a vehicle battery from a generator includes a positive feedback circuit for controlling the markspace ratio of the generator field winding supply. The regulator components include silicon chips mounted on a printed circuit board, and a blade which conducts heat from an output transistor to a container. In the circuit shown, a potential divider 15, 16 senses the voltage across a battery connected to terminals 11, 14. The field winding of the generator, which may be an alternator, is connected across terminals 12, 13 and is supplied through a Darlington pair 21, 22 when a transistor 18, controlled by Zener diode 17, is turned off. When the battery voltage increases, the diode 17 conducts and turns a transistor 18 which diverts base current from transistor 21 and turns it off. An RC circuit 23, 24 provides positive feedback causing oscillation between the conductive and non-conductive states. A capacitor 25 reduces radio interference, and a resistor 26 provides stabilizing negative feedback. The resistor 16 may be a ceramic which is abraded to produce a desired regulated output level. Transistors 18, 21, 22 and diode 17 are formed as integrated circuit silicon chips mounted on a printed circuit in a container. A conductive blade (32) enables heat to flow from transistor 22 to the container, Figs. 2-5 (not shown).

Apparatus for gas analysis in which it is necessary to maintain a constant number of molecules of gas to be analyzed in an analysis chamber 1, e.g. an optical absorption analyzer, comprises a heat-insulated vessel 4 open to atmosphere containing the analysis chamber 1, and also a closed manometric pressure responsive cell 5 with a movable wall 8 connected so as to operate a switch 9 in circuit with a heater 6, the arrangement being such that variations of atmospheric pressure which would affect the number of molecules of gas in the analysis chamber 1 are compensated for by raising or lowering of the temperature of the chamber 1 inside the vessel 4 by switching on or off the heater 6. Dynamic pressure losses at the outlet 3 of the chamber 1 may be compensated by the provision of a spring (not shown) acting on the wall 8 the spring pressure being equivalent to the pressure loss, and also the operational temperature may be made adjustable by providing a device for varying the volume of the cell 5, which will contain a gas at a reference pressure corresponding to the minimum atmospheric pressure encountered at the place of use of the apparatus. Variations of temperature of the gas in the analysis chamber 1 may be accounted for by providing a modified construction in which the gases leaving the chamber 1 pass to the outlet 3 via a jacket surrounding the cell 5. In another construction the interior of the cell 5 is connected to one arm of a mercury containing manometer with contacts acting as a mercury level switch in place of the mechanical connection shown in the figure.

Abstract: 1298820 Analogue to digital converters INDUSTRIE AUTOMATION GmbH & CO 18 Dec 1969 [18 Dec 1968] 61854/69 Heading G4H In an analogue to digital converter in which the analogue input E to be converted is compared in a comparator V with a reference signal U D  which is progressively switched in steps until the comparator detects that the reference signal has changed from being smaller to being larger than the input signal or viceversa there is provided a contact d u1  which initially feeds the mid-value of the reference signal to the comparator, this value being compared with the signal E, and a contact V u  controlled by the comparator to switch, by means of contacts d 11 -d 52 , the reference signal only for values above the mid-value or only for values below the mid-value depending on the initial comparision. The reference signal is tapped from a resistor chain in which resistors R r1  and R l1  have five times the value of each of the other resistors. Initially the contacts d 12 - d 52 , which are controlled by relays D 1 -D 5 , are positioned so that the mid-value of the reference signal is compared with the signal E. If the signal E is less than the reference signal the comparator V moves the contact V u  to energize the relay D 1  thus closing the contact d 12  and opening the contact d 11 . If the comparator now measures a positive difference voltage the contact V u  enables energization of a relay D u  to change over the contact d u1 , close contact d u2  and thus sequentially close contacts d 2 -d 5  to switch in reference signals of 1/10 U D , 2/10 U D , &c. until the reference voltage equals the signal E whereupon the contact V u  returns to its central position, The relays D 2 -D 5  also control switches which enable the energization of counting tubes or printers representing the digits 0 to 9 in a decoder.

Title: Discharging rotary furnaces
IPC: F27B7/33
Filed: 1978-08-07
Abstract: A refractory siphon tube 14 is inserted through the axial discharge opening of a rotary melting furnace 2 and down through the slag 9 into the metal 8 within the furnace. Molten metal is withdrawn continuously by suction through the tube 14 into an enclosed chamber 13 maintained under a controlled negative suction pressure through a suction manifold connecting with a receiver 19 vacuum pump 20 and pressure controller 21. The enclosed chamber discharges by gravity through a bottom opening, either emptying into a launder with an overflow weir, 52 or discharging directly out through a bottom nozzle equipped with a slide gate shut-off. The metal is discharged continuously at a controlled rate irrespective of any variations in the feed rate and metal depth in the furnace. The metal depth can be varied by periodically varying the suction pressure and thus can provide for intermittent slag discharge by overflowing the annular discharge opening. The depth of the enclosed chamber may be varied as desired, a high vacuum pressure being logically employed with the deeper units which thus also act as vacuum degassers for removing dissolved gases in the molten metal. <IMAGE>
