Title: Improvements in or relating to automatic electric regulators
IPC: G05F1/00
Filed: 1936-07-24
Abstract: 478,681. Automatic control systems. SOMERVILLE. T. B., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. July 24, 1936, No. 20568. [Class 38 (iv)] Electromotive force, power, &c.-Apparatus for regulating any condition of an electric circuit, other than its frequency, and adapted to adjust for example, a speed governor in the case of load control, or an induction regulator or stepped transformer in voltage control, comprises servo-means such as a reversible electric motor for effecting the adjustment under the control of switching means operated respectively by a timing device and by an integrating device responsive to the controlled condition which upon departure from synchronism between the two devices at the end of each period determined by the timing device applies to a control circuit an impulse of duration determined by the extent of the departure which effects a correction and also wholly or partly restores synchronism, and so prevents hunting. Means may be included to limit the degree of departure and to prevent adjustment with an impulse of short duration. The speed of the timing means may be subject to adjustment to determine the duration of the periods or to variation in accordance with a desired variation in the quantity. A cam 25 is driven by known means 5, 7, 12, so as to integrate the power in a circuit 1, and a similar cam 41 is driven similarly at a substantially constant speed. Switch members 26, 42 are operated respectively by the cams to make contacts alternately and simultaneously at 30, 37 and 29, 40 so long as the cams are in synchronism. When the power integrated by a revolution of the cam 25 is such as to cause this cam to be slow on cam 41 a circuit will be made between contacts 29, 37 through relay coil 36a. Contact 56 will thus close for a period depending on the degree of departure from synchronism and a motor 60 will be energized to apply a correction during this period; at the same time a contact 55 will be opened to stop the drive of the timing cam 41 until synchronism is again attained by the continued movement of cam 25. Conversely contacts 30, 40 will close simultaneously for a period depending on the degree of departure in the other direction when the integrated power is too great and relay 38 will be energized to effect an opposite correction by closing contacts 57 and to restore synchronism by interrupting at contacts 11 the drive to cam 25. To limit the degree of asynchronism a constant torque is applied by elements 5a, 17, 18 through the contacts 11. In a modification, Fig. 2 (not shown) for controlling voltage by adjusting an induction regulator, in which the timing cam is not necessarily electrically driven asynchronism is limited by a mechanical device interconnecting the cams and synchronism is restored by contacts controlling the circuits of main and auxiliary driying coils on the integrating device. A time delay relay may be inserted in the circuit of the adjusting motor.

Abstract: 757,153. Clamps. GEWERKSCHAFT REUSS. July 15, 1954 [July 15, 1953], No. 20706/54. Class 44. [Also in Group XXVIII] In a quick-release coupling for flanged tubes comprising a plurality of U-shaped clips 5, 5<SP>1</SP>, Fig. 1, the arms 6, Fig. 2, of each member having sloping inside faces which are pressed radially against the flanges 3, 4, there is an undivided flexible steel-band 20, Fig. 1, which connects the clips with each other and with a tensioning device 23, 24, the tightening of the latter, by the action of the sloping clip faces against the flanges 3, 4 serving to press the flanges together. Packing, not shown, may be interposed between the flanges. One clip 5<SP>1</SP> is enlarged and formed with a slot in each flank so that upon the tensioning wedge 23 being driven both through the slots and a movable bush 24, Fig. 2, therebetween, the clips are urged against the flanges due to effective shortening of the band 20, the ends of which are connected to the bush 24 and clip 51, respectively. Upon the wedge being partly withdrawn the coupling is released due to the resilience of the band. One of the two arms 6, of each clip may be longer than the other to prevent unintentional detachment of the clips from one pipe whilst the other pipe is released; with this construction the wedge must be completely removed, after withdrawing a locking member 18 therefrom, before the coupling can be disconnected.

Abstract: 961,030. Granulating-machines. MOTOMCO Inc. June 16, 1960 [June 16, 1959], No. 21250/60. Addition to 926,409. Heading B5A. [Also in Division B1] A readily dispersible, granular, free-flowing and substantially dust-free material is obtained from a solid, finely divided material when the latter is fluidized and conveyed on a vibrating inclined surface while being sprayed with a swelling agent, new surfaces of the particles continuously being exposed to the spray by the vibration which also separates the treated particles from the untreated ones, the former being conveyed downwardly on the inclined vibrating surface while the latter are conveyed upwardly to be subsequently exposed to spraying. In one form of apparatus (Fig. 1), finely divided material 12 is fed through a hopper 10 to the trough 1, the bottom plate 5 of which is inclined at an angle of 10 degrees to 60 degrees, preferably 15 degrees to 35 degrees, with the horizontal and is vibrated by a device 8, such as an electromagnetic, pneumatic, spring or eccentric-operated vibrator. The upper and major portion of the plate 5 is unsupported, the ratio of supported to unsupported surface being, for instance, 1:1“ to 1: 2. The vibration rate is 1000 to 5000, preferably 3000 to 4000, impulses per min. at strokes of <SP>1</SP>/ 125  to # inch, preferably <SP>1</SP>/ 64  to <SP>1</SP>/ 16  inch. A spraying device 11 impinges a spray or mist of a desired swelling agent on the material 12 and the granulated material is removed through outlet 4. At least the lower portion of the bottom plate 5 may be heated, e.g. by the use of infra-red radiation. It is advantageous to incline the vibrating device 8 so that the treated particles are repeatedly thrown upwardly and forwardly in synchronism with the pulsations. In a modified apparatus (Fig. 5), the trough 1 is provided with an inclined shoot 23 so that untreated material removed along with the granulated material flows back into the vibrating trough, thus increasing the efficiency of granulation to essentially 100% per pass. The angle of inclination of the shoot 23 should be less than that of the trough 1, preferably 2 degrees to 5 degrees less.
