Title: Improvements in apparatus for cooling clinker and the like
IPC: F27B7/38
Filed: 1926-08-10
Abstract: 274,656. Allen & Co., Ltd., E., and Coles, W. J. Aug. 10, 1926. Ccoling discharged materials.-A rotary cooling drum for cement clinker and the like is of short length relative to its diameter, e.g. its length is only slightly greater than the diameter, and is rotated at a high speed, e.g. 25 revolutions per minute, so that the material is carried round by friction with the drum, cascaders being thus unnecessary. The drum a, shown as receiving clinkers from rotary cement kiln d, is lined for a portion of its length with fire-brick e, and is provided with a central tyre b, supported on rollers, and a toothed driving ring c. To ensure that there shall always be a predetermined charge in the drum it is tapered towards the discharge end or, as shown., provided with an internal annular diaphragm f. The drum is further supported in a bearing i and, on the discharge side of the diaphragm f, there is provided an outlet port g adapted to discharge into a hood h which communicates with an elevator. The cooling is effected by a current of air supplied by a fan l, a perforated screen k being provided to equalize the blast over the whole cross-section of the drum.

Title: An aerial assembly
IPC: H01Q3/44
Filed: 1962-05-22
Abstract: 1,005,221. Aerials. C.S.F. COMPAGNIE GENERALE TELEGRAPHIE SANS FIL. May 22, 1962 [May 30, 1961], No. 19737/62. Heading H4A. Relates to a directional aerial system comprising an array of equi-spaced radiating elements 2 coupled to a circular waveguide 1, as shown in Fig. 2, the direction of maximum transmission or reception # relative to the axis of the waveguide 1 being controlled by adjustment of the phase velocity of the waves in the guide. When used for transmission a linearly polarized wave launched in the direction left to right in the guide by a probe 4, Fig. 3, coupled to a transmitter 3 is converted by a #/4 dielectric strip 5 into a right-hand circularly polarized wave whose wave number K+ (K=2#/#) and hence phase velocity, varies as shown in Fig. 5 with the intensity of a variable axial magnetic field H applied by means of a solenoid 7 to a ferrite rod 6 in the guide, a directional beam of radiation being produced by the elements 2 only when the value of K+ is less than a predetermined value Ko related to its free space value. In such a system it is found that the presence of the elements 2 produces in the guide 1 a secondary wave of smaller amplitude also travelling from left to right but circularly polarized in the opposite sense, i.e. left-hand. The wave number K- of this secondary wave varies with H as shown in Fig. 5 and in order to prevent secondary radiation lobes due to the secondary wave, the value of H is maintained within the limits Hm and HM as shown in Fig. 5, so that K- is always greater than Ko. When the system is used for reception a wave received from the direction # will produce in the guide 1 a left-hand circularly polarized wave of wave number K- travelling in the direction right to left which is converted by the dielectric - strip 5 into a plane polarized wave polarized in a plane orthogonal to that of the wave launched by the probe 4, the received wave being collected by a probe 9, Fig. 4 (not shown), orthogonal to the probe 4.

Title: Electric measuring, indicating, recording or controlling apparatus
IPC: G01R27/02
Filed: 1942-05-01
Abstract: 558,647. Impedance measurements. REDIFFUSION, Ltd., and ADORJAN, P. May 1, 1942, No. 19869/43. Divided out of 558,614. [Class 37] An apparatus for observing the impedance of a load comprises means serving to obtain a direct potential which is a function of the voltage of an alternating or pulsating E.M.F. being applied to the load, means serving to obtain a direct potential which is a function of the current being passed through the load by this E.M.F., and means automatically operative, when the relative values of these potentials depart from a predetermined relationship, to re-establish this relationship and in so doing perform an indicating, recording, or controlling operation. In the apparatus shown in Fig. 1 a transformer 4 supplies a load circuit represented by a resistance 5, inductance 6, and condenser 7, which circuit may be, for example, a public telephone line or a broadcast rediffusion network. Two pairs of terminals 8, 9 and 10, 11 are normally connected as shown in dotted lines but for measuring the impedance of the load they are connected to the measuring apparatus by terminal leads 12, 13, 14, 15. A potential transformer 16 and a current transformer 17 are connected as shown. Rectifiers 18, 19 are connected in series with the secondary windings of these transformers and a resistance 21 having a sliding contact 22 is connected between sides of similar polarity. The slider 21 is. adjusted by means of a reversible motor 20 until the potentials across the two halves of the resistance 21 are equal, the position of the slider then being dependent on the impedance of the load circuit at the frequency of the alternating E.M.F. A scale calibrated in terms of impedance may be provided. Fig. 2 shows a modification in which the change in load on the transformers 16, 17 by movement of the slider 22 is avoided. A rectifier 23 and resistor 24 are connected to the sliding contact 22 of a potentiometer resistance 25, which is connected in series with a fixed resistor 26 across the secondary of the transformer 16. Across the secondary of the transformer 17 is connected a tapped resistor 27 with a tap-selecting switch 28. This is connected to a rectifier 29 and resistor 30. A reversible motor 20 is connected between corresponding ends of the resistors 24, 30, and adjusts the slider 22 of the potentiometer resistance 25. The tapping switch 28 enables the range to be changed. The transformers 16, 17 may be tuned or filter networks may be provided so that the values of the two direct potentials are primarily dependent on E.M.F.s of a predetermined frequency. Electromagnetically operated or controlled stepping mechanism may be employed instead of a reversible motor. Differential relays may be employed to connect additional amplifying equipment in accordance with the impedance of the load on a main amplifier. Specifications 558,614, 558,645 and 558,646 are referred to.

Filed: 1921-07-26
Abstract: 185,593. Vickers, Ltd., and McKechnie, Sir J. July 26, 1921. Regulating.-In gear for controlling an engine and reversing it under mechanical power, the starting-air and fuel supplies are under the control of levers held in the off position by an interlocking-device during the movement of the reversing-mechanism and released for actuation only after the reversing movement has been completed under power. In the form shown, the reversing-lever is connected by a link to an arm on a locking-shaft 24 carrying notched discs 23, 48, Figs. 4 and 5. The disc 23 is engaged by a lever 20 when a starting-lever is actuated, and the disc 48 is normally engaged by a lever 45 released by the depression of a fuel cut-off lever 40, so that reversal can only be effected when the supplies of fuel and starting-air are both cut off. To prevent operation of the starting and fuel cut-off levers 15, 40 except when the reversing-mechanism is in one or other of its extreme positions, a pair of notched discs 120 connected to the levers 15, 40 are normally engaged by levers 122, Fig. 6, connected by a spring 122a and engaging an arm 130 on the locking-shaft 24. The levers 122 are controlled by a lever 123 pivoted at 124 and connected by a link 125 to the reversing-mechanism. The fuelspraying valves 25 are actuated by cams 26 on the shaft 14 through levers 28 pivoted on eccentrics 29 on the shaft 30. The eccentrics 29 are adjusted, for controlling or cutting off the fuel supply, by the lever 40 acting through a link 41 and a lever 42 carried by a shaft 36, on which are pivoted levers 35 connected to the eccentrics 29 by links 34, 32 and levers 33, 31. The valves may be controlled individually by means of a handle 38 on the lever 35, which is normally in engagement with a common control lever 37 on the shaft 36, but can be disengaged and brought into engagement with a fixed arm 39.

Abstract: 1,043,556. Rolling. ARMCO STEEL CORPORATION. May 21, 1963 [May 31, 1962], No. 20156/63. Heading B3M. [Also in Division G3] A tandem train of cold rolling stands for strip rolling includes entrance and exit stands having automatic screwdown control, and an intermediate stand having speed control of its rolls, the entrance stand having speed control dependent on the strip tension after the stand, and the exit stand having speed control dependent on the strip tension before the stand and also dependent on changes in roll loading in the stand. Strip 6 from a decoiler 5 passes to a coiler 7 by way of 4-high stands 1 to 4. X-ray gauges 8 and 11 supply signals to signal impulse generators with variable time delay 9, 10 and 12 to control the screwdown of stands 1, or 2 and 4. Stand 3 which is a stand near to the middle of the train is controlled only by the I.R. system in which a secondary field coil in a motor-generator set causes compensation for changes in load on the working rolls by varying the motor speed. Stands 1 and 2 have a tensiometer control and stand 4 a combination of I.R. and tensiometer control. In each tensiometer control system the strip tension is measured by a meter 13, 29 or 44, compared with a reference 16, 32 or 47 and the output signal fed to a generator field coil to appropriately vary the speed of the working rolls. Tensiometers 13 and 29 control stands 1 and 2 respectively while tensiometer 44 controls the following stand 4. A master rheostat 20 is mechanically connected to rheostats 50, 35 and 19 to give the field control devices the required sensitivity for different speeds.

Title: Improvements in railway track circuits
IPC: B61L1/18
Filed: 1937-07-21
Abstract: 488,240. Railway signalling systems. GENERAL RAILWAY SIGNAL CO. July 21, 1937, No. 20249. Convention date, Aug. 21, 1936. [Class 105] The supply to a track circuit with a directly connected track relay which is maintained energized consists of voltage pulses having a steep wave form and of short duration relatively to the time space between the pulses. Such a supply may be derived from a normal sinusoidal wave form supply by a transformer having a secondary winding 8 on a core limb which becomes saturated..In parallel to this limb is a limb 10 with an air gap. When a supply from the generator G and of normal sinusoidal wave form A, Fig. 3, is applied to the primary winding 7 of the transformer the fiux in the secondary limb is of the wave form B and so the secondary winding 8 gives the spaced voltage pulses C of steep wave form and alternating in polarity. For direct-current track relays the transformer secondary is connected through a rectifier to allow only unidirectional pulses. This latter arrangement provides for ballast compensation in a manner similar to the arrangement described in Specification 445,515,

A temperature control system incorporating a Wheatstone bridge and having an amplifier for the bridge output operating a switching relay for controlling a temperature regulating device, the amplifier including adjustable positive feed-back whereby an adjustable differential is achieved in the operation of the relay. As shown, a Wheatstone bridge comprises a platinum resistor 2 serving the temperature to be controlled, a manually adjustable resistor R8 for setting the desired temperature and a pre-set resistor R7 for determining the range of temperature over which resistor R8 has control. The output of the bridge is fed to a balanced push-pull transistorised amplifier having stages 9-12 and a relay 13, for operating a temperature regulating device, connected in series with the collector of a transistor in stage 12. Positive feedback to stage 9 from stage 12 is derived from a slider of a potentiometer R2, connected as shown, to provide an adjustable differential in the operation of the relay 13. Balancing of stage 9 is effected through a potentiometer R1 having a slider connected to the negative side of the circuit. The relay 13 is slugged by a capacitor C3. For certain applications two amplifiers are connected to the bridge and their associated relays are arranged to operate at slightly different temperatures by adjustment of the balance potentiometers R1. The resistor R7 can be remotely mounted from the rest of the instrument and the amplifier can be constructed as a plug-in printed circuit panel.
