Title: Improvements in the control of parallelled alternating current electric systems
IPC: H02J3/38
Filed: 1935-07-16
Abstract: 443,942. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(AUgemeine Elektricitõts Ges. ; 2, Friedrich Karl-Ufer, Berlin) July 16, 1935, No. 20280. [Class 38 (v)] In a switching arrangement for separating two sources of A.C. when they fall out of synchronism, means responsive to a current in excess of a predetermined value which occurs when hunting is present, is employed forinitiating the operation of a relay responsive to the hunting frequency which controls the switching operation. As shown in the Figure, the control relay comprises an arm 5 driven at a speed dependent upon the system frequency by a synchronous motor 26 through a magnetic clutch 22 and a second arm 6 driven at a speed dependent upon the hunting frequency by a step - by-step mechanism comprising an electromagnet 27 whose spring-retracted core 10 acts as a pawl to step round a ratchet wheel 7 connected to the arm 6 through gearing 8. On the occurrence of the excess current which is associated with hunting, the arm 6 commences to move and catches up with the arm 5 when a predetermined value of hunting frequency is exceeded. 'The knob 1 then closes contacts 2 in the circuit of a relay 12 which closes at contacts 13 a maintaining circuit and at contacts 14 the circuit of a trip coil 25. The arm 6 ceases to move as the circuit-breaker connecting the controlled circuit is opened. The arm 5, however, continues to revolve until the knob 3 engages and closes contact 4. This energizes relay 15 which completes its maintaining circuit at contact 16 and energizes a time-lag relay 19 through contact 17, which relay controls the clutch 22 so that the movement of the arm 5 is also arrested. The circuit of relay 12 is also interrupted at contacts 18 of relay 15 so that the arrangement is again ready for operation. The relays may be brought into their initial positions by operation of pushbutton 20.

Title: Improvements in gauging machines
IPC: B07C5/06
Filed: 1922-07-25
Abstract: 203,472. Marks, E. C. R., (Bock Bearing Co.). July 25, 1922. Separating and sorting gauges.-A machine for gauging and sorting objects such as bearing rollers comprises means for feeding automatically y the objects to calipering jaws mounted on the rim of a rotating table, the diameter of the object through linkwork giving a setting to a brush which ultimately, through one of a series ot stepped contacts closes a circuit and causes the positive ejection of the object to a sorting compartment. The fixed frame 13 supports a table 15, rotated by a wormwheel 16 from a pulley (not shown), carrying a gear 78 driving, through wheels 100, 98 in a shaft 89 carrying a cam 91, and, through a wheel 77, a sleeve 76 upon which is mounted a feed table 80. The rotating feed table 80 has, in its surface, notches into which the objects are fed through an opening 88. When a recess. in the table registers with a calipering- device, mounted on the table 15, the cam 91 actuates a pivoted lever 94 which carries the object between the calipering jaws. Ten identical calipering devices are mounted upon the edge of the rotating table, 15 each device comprising a frame 26, Fig. 3<a>, fixed to the table and carrying a fixed jaw 33 and a movable jaw 27. The latter is pressed downward by a spring abutting a plate 37 but can be moved upwards for releasing the objects through links 47, 46<1>, 43 by a cam on a shaft 46. A notch in the movable jaw, through knife-edged levers 58, 56, gives a setting to an arm 62, mounted on an adjustable bracket carrying a brush 63. This brush as the table 15 rotates passes over a series of contacts stepped upwards and mounted upon a stationary table 21, and ultimately through contacts 72, 73 completes circuit through a solenoid 126 which breaks circuit through a solenoid 118 and allows a spring 114 to turn a shaft 46 carrying a cam 45 into cocked position for tripping the lever 43 and releasing the object. The object is correctly positioned in the jaws of the callipering device by a stationary cam 110 first 'releasing the moving jaw 27 whereupon a spring plunger 106 presses the object against a guide 94. The plunger 106 assists the ejection of the objects into the sorting compartments. In operation, the feed table transfers objects to each of the calipering devices, the objects are then positioned and the appropriate brush 63 is set. When this brush touches a contact the object is released and ejected to a compartment associated with the contact.

Title: Key-actuated electrical musical instruments
IPC: G10H1/057
Filed: 1966-05-09
Abstract: 1,133,140. Musical instruments. HAMMOND CORP. 9 May, 1966 [24 May, 1965], No. 20360/66. Heading G5J. Tone signals in a musical instrument are amplitude modulated by a diode gate in accordance with applied gating potentials. In the electrophonic organ shown in Fig. 1 tone signals from each tone generator 10 are potential divided as at R16, R18 and applied through a corresponding diode gate 24, 30 to a common terminal 36 connected to the amplifier. In accordance with the setting of a common hand operated selector switch 62 various low or negative potentials can be applied to each diode gate as at 38 to maintain each in the cutoff condition to various degrees of hardness. When the corresponding key switch 46 is closed a positive potential sufficient to open the gate is applied to its terminal 38 and to a corresponding capacitor C52 which it charges. Thus each tone is sounded continuously while the associated key is maintained closed and decays exponentially at a rate dependent on the setting of the selector switch when the key is released. In a modification (Fig. 9) each key switch 86 is connected to its terminal 38 and its capacitor C88 through a differentiating capacitor C80. Thus each tone sounds in decaying manner even if the corresponding key is maintained closed. Diodes 90 may be included to prevent sudden discharge when the keys are released thus causing the tones sounded to continue but at increased rates of decay. Diode 24 is biased to conduct before, and be cut off after the diode 30 and this is stated to provide a better decay envelope.

[Also in Divisions B1, C3 and G2] A process for monitoring the concentration of living polymer chains in a homogeneous solution polymerization reaction mixture comprises removing a stream therefrom, treating a portion of the stream with a de-activating agent to produce a de-activated reference portion, and comparing the light absorbance characteristics of the reference portion with those of a second, active portion of the stream at the same narrow band wavelength of transmitted radiation. The results may be shown graphically or used to control and modify the polymerization process, particularly in relation to molecular weight and-distribution. In the preferred procedure, samples are removed from polymerization zone 10 and passed in part via line 18 to cell 30 and in part via line 16 to cell 28. Light from source 34 passes via filter 36 to cells 28 and 30, and thence via filters 42 and 44 to photo-tubes 46 and 48, the output from which is fed to control or record station 50. The sample portion flowing in 18 is de-activated from store 20 via line 22. Partial de-activation of the sample portion flowing in 16 may also be effected via line 26. The process may also be applied to monitoring the purification of reactants prior to polymerization. In examples, polybutadiene, polyisoprene, butadiene-styrene random and block copolymers are prepared using butyl lithium initiator in cyclohexane or cyclohexaneisopentane mixture. Analogous monomers, solvents and initiators are-stated in one example to give similar results.
