Title: A device for use in filling tumblers and other containers with liquids liable to froth
IPC: B67C3/26
Filed: 1937-05-10
Abstract: 493,641. Dispensing liquids. HARVEY, R. May 10, 1937, Nos. 13254 and 28427. [Classes 106 (v) and 116] A device for filling tumblers and the like with a liquid liable to froth comprises a container 2, Fig. 1, having at the base an inlet 4 and outlet 5 controlled by a rotary cock 6, and an additional inlet valve 11 operated by a freely moving float 14 which rises on the top of the liquid and is of such a size as to cover substantially the whole surface of the liquid and so prevent contact of the liquid with the atmosphere. The cock is formed with a diametric passage 7 and with a right-angled passage 8, the two passages being connected by an axial bore 9. In one position of the cock both inlet and outlet are closed ; in another the inlet and outlet are directly connected and the cock acts as an ordinary tap. In a third position the outlet is closed and liquid passes from the inlet, through a chamber 10 to the container 2. When the float reaches an adjustable stop 18 on a spindle 12, the spindle is raised to close an air vent 16 by means of a valve 15 and the inlet from the chamber 10 to the container by means of a valve 11 which latter is then kept closed by the liquid pressure in the chamber 10. In the fourth position of the cock both chamber 10 and container 2 are connected with the outlet. In a modified form, Fig. 11, liquid is supplied through a counter fixture 25 to short vertical passages 40, 41 at the ends of radial passages 37, 38 in a fixed valve member 30 at the base of a container 35. On rotating container 35 and a moving valve member 31, arcuate passages 46, 47 put the passages 40, 41 into communication with the container which fills with liquid. This rotary movement of the container operates through a spindle 48 and lever 51 to tension a spring and a locking device co-operating with a roller 53 on the lever 51 holds the container in the filling position. When a float 36 raises a ring 60 and spindle 59 the locking device is released and the container and valve automatically rotated to cut off the supply. Further rotation effects the discharge of the container.

Title: Control systems for rolling mills
Inventor: SIMS RAYMOND BERNARD
IPC: B21B37/16
Filed: 1961-04-13
Abstract: 999, 761. Automatic control of rolling mills. DAVY & UNITED INSTRUMENTS Ltd. April 12, 1962 [April 13,1961],No. 13318/61. Heading G3R. In an automatic control system for a tandem rolling mill, errors in thickness of the rolled material at one stand, detected by means responsive to the rolling load at that stand, control roll separation at that stand by adjusting means which also determine proportional adjustment of roll separation at a preceding stand. As shown, in a six-stand hot strip finishing mill the strip moves from left to right and signals dependent on the rolling load and screw-down position at stand F3, derived from pick-offs 12 and 15 respectively, are compared with a signal, representing desired thickness, from a device 16 and the resultant signal, representing thickness error, applied through an amplifier 18 to control a follow-up servomotor 20 adjusting an A.C. signal generator 22 to a corresponding position. The output of signal generator 22 is applied to a gating circuit 25 so that when the error exceeds a value determined by the setting of a device 26, a signal is applied through a gating circuit 27 to actuate a screw-down motor 13 of stand F3 to partially correct the error which is further corrected by the proportional adjustment, through a synchro 28, of screw down motors associated with preceding stands F 1 , F 2 . Operation of the screw-down motor is prevented if the rolling load becomes excessive by a signal applied from load pick-off 12 to gating device 25 through a limiting device 36. By changing over a switch 37 temporarily at the start of rolling a servomotor 39 sets device 16 to correspond with the thickness of the strip which is thereafter maintained at that value. Tension detectors L1-2 to L5- 6 between each pair of stands respectively control the speeds of the rolls of adjacent stands to maintain constant tensions. A further control system responsive to the thickness of the strip at stand F5 which controls the speed of the rolls of stand F6 for small errors and the screw-down motors of stands F4 and F5 for large errors may be provided.

Title: Improvements in or relating to electric motor control systems
IPC: H02P7/282
Filed: 1956-05-02
Abstract: 802,184. Automatic speed-control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 2, 1956 [May 6, 1955], No. 13494/56. Class 38 (4). In a speed regulating system for a D.C. motor 1 wherein a signal proportional to speed developed in a tachometer generator 9 is compared with the same type of signal from a reference source 16 to produce an error signal, a transistor switch 49 coupling the motor to a direct current source 57 through the emitter to collector conduction path is selectively biased to one extreme ofcollector conduction current (saturation or cut-off) and a pulse generator 26 is arranged to produce pulses which bias the transistor switch to the other extreme in a manner whereby the average collector current is such as to restore the motor speed to the desired speed in accordance with the error signal. Triangular pulses derived from alternating current source 22 by rectifier 23 and linear and non-linear resistors 27 and 25, are applied to the base of transistor 41 and the emitter which is biased from point 18 in the combining circuit 13 determines the peak amplitude. The output across resistor 35 is limited by a Zener diode 37 to supply rectangular pulses the duration of which is proportional to the error signal to the base of transistor 49. A modified arrangement in which the frequency of an A.C. tachometer generator is compared with the frequency of a reference source to produce from a singleshot transistor multivibrator, constant width pulses having a repetition rate proportional to the error signal is described with reference to Fig. 2, (not shown). Reference has been directed by the Comptroller to Specification 775,827.

Abstract: 1,094,001. Error correcting means. GENERAL ELECTRIC CO. Ltd. March 30, 1966 [March 30, 1965], No. 13534/65. Heading H4P. Apparatus for correcting errors in a received signal comprises means for determining which one of a plurality of discrete states the received signal was in longest during a bit period. In the embodiment describod, output signals from a teleprinter on six leads 4 (Fig. 1) are successively sampled in a multiplexer 5, the time division multiplexed signal being fed to a transmitter where it modulates a radio frequency carrier wave in a conventional manner. The transmitted signal received by an aerial 8 is fed to a receiver 9 for demodulating and then demultiplexed before being fed to a distributer 11. A second group of six binary coded signals are applied to the distributer 11, the signals having been received via a second radio link, and a third group of six binary coded signals from local signal sources 12 are also fed to the distributer where they are rearranged into three different groups of six signals each. The signals of one of the new groups are fed via error correction circuits 15 to e.g. teleprinters, the other groups being fed to multiplexers where they are time division multiplexed for transmission to a further part of the system. The error correction circuit (Fig. 2) comprises a six-stage shift register 28 which receives a binary signal, the shift register operating under the control of clock pulses having a repetition rate equal to eight times the digit rate of the received signal. The outputs from each stage of the register together with the received signal are added and applied to a level detecting circuit 29 which produces a signal " 1 " or " 0 " depending on whether the input signal is greater or less than half the magnitude of its input when all the inputs are one. The output signals from the level detector 29 are fed to logic circuitry including two monostable circuits 35, 36 which when triggered to their unstabled state remain in that state for a duration corresponding to seven-eighths of a bit period, so that any spurious short pulses are ignored.

Title: Process of and apparatus for bright annealing metals
IPC: C21D1/74
Filed: 1929-05-03
Abstract: 332,656. Metallges. Akt.-Ges., Forster, H. von, and Lay, E. May 3, 1929. Resistance furnaces.-Apparatus for annealing metal sheets, wire and the like in a non-oxidizing atmosphere comprises an open-bottomed furnace 1 disposed above a charging and cooling chamber 7, the two chambers being relatively movable in a vertical direction so that they can be brought into close contact, a gas-tight joint being made by the engagement of a flange 7a on the upper end of the chamber 7 with the wall surrounding the opening in the bottom of the furnace. As shown, the chamber 7 is carried by a carriage 10 which is raised to press the chamber tightly against the furnace by a ram 11. A modified construction is described in which the chamber 7 is constituted by a pit, the furnace 1 being movably mounted so that it may be lowered on to and raised from the mouth of the pit. A non- oxidizing atmosphere is maintained in both chambers by supplying combustible gas, e.g. hydrogen, through pipes 4, 12, the chamber 7 being provided with a safety device 20 and with an outlet 13 to which a flame 14 of the escaping gas is maintained. The charge 16 is disposed upon a support 17 which is lowered into the chamber 7, the latter being closed by a cover 6 and run into position below the furnace. The cover 6 fits into a recess in a slide 5 which is withdrawn and a rod 3 connected at 18 with the support 17 which can thus be drawn upwardly into the furnace. On the termination of the heating operation the charge is lowered into the chamber 7, the rod 3 detachade, and the cover 6 replaced by returning the slide 5. The chamber 7 is then removed from the furnace and the charge allowed to cool, the cover 6 being tightened, if desired, by clamps 15. By employnig a series of chambers 7, the apparatus can be operated continuously. A modification is described in which the cover 6 is constituted by an upper plate of the charge support 17, the slide 5 being in this case omitted. The chamber 7 may be formed around its upper end with an annular sealing-trough to receive an additional bell-shaped cover and may also be provided with a water-jacket to accelerate the cooling, the supply of inert gas being taken from a gas-holder of the floating bell type which prevents fall of pressure and consequent infiltration of air. Fig. 5 shows a further construction suitable for use when impure coal or producer gas is used as the inert atmosphere, the charge 16 being contained in a thin-walled pot 32 between the cover 26 of which and a perforated plate 34 is disposed purifying material 33 such as cast-iron turnings. When the apparatus is used for annealing copper, the first part of the cooling operation is effected by supplying steam, the steam being replaced by the inert gas when the temperature approaches that of the condensation of steam.

Abstract: 1507195 A cable device; slack take-up mechanism EMDA FABRIK ELEKTROMEDIZINISCHER UND DENTALER APPARATE GEORG HARTMAN GmbH & CO KG 4 April 1975 [6 April 1974] 13821/75 Headings B8M and B8B [Also in Division F2] A device for the withdrawal of and for taking up slack of a cable (not shown) comprises a locking means 24, 27 and a reversing device 29, 30, wherein alternate pulls on the cable cause the reversing device to move the locking means into engagement with a serrated track 8 to lock the device, and pulls between the alternate pulls cause it to disengage the locking means from the track to unlock the device. If the cable is pulled from the device-locked position (see Fig. 4) a retractable pin 29 of the reversing device moves the locking member 27 out of engagement with the track clockwise (see Fig. 1). A cam 33 having a recess, and a web 34 move clockwise so that a spring pin 31 rides up a top shank of the cam 33 and drops into the recess to define a released position of the device. By further pulling the cable the device rides along tracks 8, 10 and dispenses more cable length. The device can now be locked in the cable extended position by releasing the pull on the cable and then giving it a further pull which causes the pin 31 to drop out of the recess and to ride the bottom shank of the cam 33 to assume the locked position. If, however, the extended cable is released while the device is still in the released position a return spring 20, which is stressed due to the pulling of the cable, returns the device back to its original position to take up the cable slack. The device can then be locked in this position by pulling the cable to cause the pin 31 to drop out of the recess and assume the locked position.
