Filed: 1960-01-12
Abstract: 873,104. Automatic position control systems; converting. PERKIN-ELMER CORPORATION. Jan. 12, 1960 [Jan. 14, 1959], No. 1119/60. Classes 38 (2) and 38 (4). [Also in Group XL (b)] A system for determining the angular deviation of a distant object from a normal position and supplying a correcting error signal comprises means providing a pair of radiant energy beams modulated in phase opposition and means directing them to a reflective part of the distant object. After reflection the beams are received back at the transmitting position and that portion of the received energy passing through an entrance slit investigated. In one embodiment a truncated radiation transmissive prism 15 has its two side faces 21, 23 made reflective. Gas discharge lamps 13 and 14 are modulated about a constant level in antiphase at a frequency of 400 cycles per second and energy from them directed to a reflector 11 on the object 10 under investigation and returned back to prism 15. That part of the beam received along the axis of the system passes through the end face 24 of the prism, which acts as an entrance slit, and is directed to photomultiplier 25. When the reflector 11 is perpendicular to the optical axis of the system the beam 19 from source 14 is reflected back to surface 21 of the prism and the beam 22 from source 13 to surface 23. Only small portions of the two beams will enter the slit 24 and the 400-cycle modulation of these will cancel due to being 180 degrees out-of-phase. Any angular deviation of reflector 11 will cause one or other beam to predominate in the entrance slit and the corresponding output from photo-multiplier 25 can be fed to a phase-discriminator to derive a correction signal of appropriate sign. This is used in known manner to bring the object back to correct alignment. As described so far the tube 25 gives a zero output both when the object is correctly aligned and when it is so far displaced that the reflected beam misses the entrance slit completely. To distinguish between these two conditions the lamps 13 and 14 are also modulated in phase at a different frequency so that the slight illumination passing through slit 24 at correct alignment is capable of giving an output signal to inhibit operation of a drive which would otherwise rotate the object 10 to search for the alignment position of mirror 11. It is preferred to make the different frequency used for this purpose 800 cycles per second and to derive it from the 400 cycle signal as shown in the lamp modulation circuit of Fig. 4. Here the 400 c/sec. input is applied to transformer 26 whose secondary is centre-tapped to give out-of-phase modulating waveforms to valves 29 and 31 which control discharge tubes 13 and 14. Signals from the extremities of the secondary winding are fed respectively through resistors 34, 35 and rectifiers 36, 37 to a common output 38. This arrangement doubles the frequency and the resultant 800 c/sec. signal is applied to transformer 33 to modulate the two discharge tubes 13 and 14 in phase.

Abstract: 368,905. Master control of motors. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Clarke, J. A. ; 6144, Penn Avenue, Pittsburg, U.S.A.) Jan. 13, 1931, No. 1131. Convention date, Jan. 30, 1930. [Class 38 (iii).] Checked by motor current.-A number of accelerating switches for a vehicle motor are controlled by a sequence drum which is actuated step by step under the control of a sequence relay and a current limit relay, and means are provided for effecting a step-by-step operation of the sequence drum independently of the limit relay. When a controller 17 is moved to position a, the actuating coil of a valve 32 of an air engine 16 is energised, and the engine is stationary. On moving the controller 17 to position b, the energizing coil of a valve 35 ot the engine 16 is energized over contacts of a sequence relay 39 and a current relay 41. The sequence drum 15 is thus driven by the air engine until a contact 48 is engaged by a contact 30 when the relay 39 is energized to break the previous circuit of the coil of the valve 35. A second circuit for this coil is provided, however, by a contact 49 engaging the contact 30, so that the sequence drum continues. to move until the contacts 48, 49 leave the first projecting portion of the contact 30. During this movement an accelerating relay 13 is closed to exclude part of a resistance 11 in the motor circuit. Thus when the sequence drum has come to rest, with the contacts 48, 49 situated between two of the projections on the contact 30, the relay 39 is de-energised and after a time period sufficient to allow the current relay 41 to operate, falls to re-close its contacts, and then a second step of resistance exclusion is carried out. To close the second accelerating relay 14, independently of the current relay 41, the controller 17 is moved to position c when a notching relay 58 is closed to supply the coil of the valve 35, independently of the relay 41. At the same time a coil 47 of the relay 39 is energized which is sufficient only to retain the relay lifted. Thus when the sequence drum has been moved one step and the relay 39 lifted, it is necessary to move the controller 17, to de-energize the coil 47, before a second step of acceleration can be made.

Abstract: 668,062. Coke ovens. SOC. DE TECHNIQUE INDUSTRIELLE. Jan. 14, 1948 [April 11, 1947], No. 1150/48. Class 51 (ii). In a coke oven in which the distillation chamber has a trapezoidal shape in horizontal cross-section and horizontal distribution ducts of uniform cross-section are provided in the lower part of the oven for the supply of gas to the heating flues and the discharge of combustion products therefrom, these ducts are provided at various points with devices for reducing their effective cross-sectional area so as to cause a drop in the pressure of the gases, whereby a greater delivery of gas to the flues running perpendicular to the wider part of the chamber and a smaller delivery of gas to the flues running perpendicular to the narrower part of the chamber may be ensured. In Fig. 1, poor gas is supplied through horizontal ducts 5 under the control of reversing valves 4 to regenerators 6, 7 communicating with heating flues 35<SP>1</SP>-35n, and the combustion products discharged through parallel ducts to a main flue 10 under the control of reversing valves 9.

Abstract: 524,862. Detecting faults. BUSHING CO., Ltd., and BROWN, W. J. Jan. 13. 1939. No. 1185. [Class 37] An insulator of a power conductor is tested by coupling to the live conductor an indicating apparatus tuned to a frequency of the order of 1500 kilocycles per second and serving to detect a high-frequency disturbance superimposed on the normal current wave, thereby indicating the presence of ionization. The indicating apparatus shown comprises a highfrequency input transformer A1, A2, a valve detector E, and an amplifier K. The primary winding A1 of the input transformer is connected across a search coil B placed in the field of the main conductor. Alternatively this winding may be connected across the secondary winding of a current transformer or in the earth lead of an ionization-free condenser. The secondary winding A2 is connected through a grid leak C and condenser D between the grid of the detector valve E and earth F. Across the secondary winding A2 is a tuning condenser G, and between the anode of the detector valve E and earth are a reaction coil H and a variable condenser J. The amplifying valve K is coupled to the detector valve E by a transformer L and includes in its anode circuit an indicating device such as a telephone P, a cathode ray oscillograph, or an ammeter. The indicating apparatus is tuned to a frequency of the order of 1500 kilocycles per second, a disturbance on the main current wave being detected as a buzz in the telephone, a deflection on the ammeter, or a disturbance on the wave form in an oscillograph. If a current of the same frequency as the main current but in opposite phase is injected the main current wave in the oscillograph is neutralized and only the image of the disturbance appears.

Abstract: 818,903. Shaft couplings. CREED & CO. Ltd. Jan. 10, 1958 [Jan. 14, 1957], No. 1283/57. Class 80 (2). [Also in Group XL (b)] In facsimile apparatus the message-supporting drum 20 is coupled to the drive-shaft 4 via a linkage 5, 12 incorporating a spring 10 so that, when the synchronous drive motor 1 is connected to shaft 4 by operation of a clutch 3, the torque load applied to the motor is limited by extension of spring 10. Subsequent contraction of spring 10, after the drum has reached synchronous speed, to realign linkage 5, 12, results in an acceleration of the drum above synchronous speed with consequent overshoot against a resilient stop 6 and a period of oscillation before the drum settles down at the correct speed and phase position. In accordance with the invention this effect is prevented by the provision of an escapement mechanism 13, 14, 17 which is set into oscillation during the contraction of spring 10 to provide a braking force. The force which is proportional to the relative velocity of the two parts of the linkage is effective to reduce the velocity to zero at the instant of alignment so that no overshoot occurs. According to a modification (not disclosed in detail) spring 10 may be allowed to accelerate drum 20 through the aligned position and the braking means arranged to become effective in response to resilient stop 10 when it acts to restore alignment.
