Title: Improvements in and relating to variable speed gears and the controls thereof, for power driven vehicles and the like
IPC: F16H15/50
Filed: 1922-02-09
Abstract: 197,715. Dolton, J. H. Feb. 9, 1922. Variable-speed and reversing epicyclic gearing comprises two continuously - variable trains with spheres as described in Specification 173,899, combined and working differentially. An anangement in which the trains are combined in a single unit is shown in Fig. 1. The two sun gear pairs 6, 7 and 8, 9 turn with a driving-shaft 1, which is in line with a driven shaft 24. The planetary spheres 10, 11 are supported respectively by a brake ring 17 and by a driven sleeve 19. The outer pairs 12, 13 and 14, 15 arc carried by an idle barrel 16 which connects the trains, which are operated to change the speed by sliding a collar 20 to which the elements 6, 9 are secured. When the ring 17 is held by a brake 18 and the collar 20 is in mid position, the trains just neutralize one another. and the sleeve 19 is at rest. On moving the collar 20 one way or the other, the sleeve 19 is driven at increasing speed in one direction or the reverse. A clutch sleeve 23 slides on the end of the shaft 24 by means of which that shaft can be clutched to the sleeve 19, or to the shaft 1 for direct driving, or can be disconnected from both. In a modification, the planetary spheres are coupled and an outer pair is differentially driven. These forms are suitable for the main driving-gear of motor-vehicles and may be operated by a lever 26, Fig. 7, in a gate 27, Fig. 8. The movements in a slot 28 correspond to the movements of the collar 20 to vary the speed forwards or backwards. The transverse movement to point O has through a lever 29, Fig. 7, moved the clutch sleeve 23, Fig. 1, to neutral. The position P, Fig. 8, corresponds to the sleeve 28 having been moved to direct drive. Single trains may alternatively be used for the differential driving of a vehicle in steering. The combined trains may be used for driving a motorboat, being situated at 2, 2<a>, Fig. 9. The separate variable-speed and reversing gears 2, 2<a> are operated by levers 50, 51, Fig. 10, normally coupled together for simultaneous operation by a bolt 52. By lateral movement the levers may be separated so that the propellers though driven by a single motor may be differently actuated to manoeuvre the vessel.
Patent GB-909032-A (GB)
Title: Method for tracing separation processes
IPC: G01N25/14
Filed: 1959-02-03
Abstract: The proportion of an element or of a com<PICT:0909032/III/1> ponent of a compound or mixture in a separated stream from a separation process such as fractional distillation, solvent extraction, crystallization, or reaction with, e.g. an acid is traced by introducing a known quantity of a radio-active isotope, isotopic with the element or component to be traced into the material to be separated and, after separation, using a radiation detector to produce pulses detected and integrated to give an indication of the amount of the component present in one of the streams from said process.  In the embodiment described a separator 10 is fed with a mixture through inlet pipe 11 via total feed meter 12.  Outlet conduits 13 and 14 lead out first and second separation products through respective flow-meters 281 and 282.  A proportion of the flow in these conduits is tapped off and fed through radio-activity measuring devices.  If the radio-active isotope is hydrogen-3, carbon-14, or some other isotope emitting soft beta rays these devices may comprise means mixing a metered amount of scintillation liquid such as terphenyl into the measuring stream and a counter cell sensitive to the light flashes produced.  The cell, as shown, comprises an opaque outer container 40 filled with a transparent liquid in which is a transparent walled coil 42 through which the sample stream passes.  One or more photo-cells 43 connected to suitable integrating devices view the interior of the cell. Intermediate product streams such as 47 may also flow from the separator and contain similar flow meters and radioactivity measuring devices.  Where three components are to be separated from a mixture of the three, e.g. in the separation of paraxylene, metaxylene and orthoxylene, three radio-active tracer liquids 21, 22 and 23 may be made available so that any one of them can be separately released into the input to give results showing the fraction of each input substance present in each of the outputs.  The invention may also be applied to the monitoring of paraxylene/ethylbenzene distillation, crystallization of paraxylene from metaxylene, hydrolysis of xylene sulphonic acids and to acetic acid present in phenol production.  In these cases hydrogen 3 and carbon 14 may be used.  Cobalt-60 and caesium-134 are also mentioned.

Abstract: 974, 761. Potentiometer voltage measurement; indicating-apparatus. FIELDEN ELECTRONICS Ltd. Jan. 25, 1961 [Feb. 8, 1960], No. 4324/60. Headings G1J and G1U. [Also in Division H3] An oscillator 17, 23, 24 has its output applied to a transistor squarer circuit 33 to derive pushpull rectangular waveform outputs applied to a transistor chopper circuit 51 for correspondingly interrupting, at oscillator frequency, a D.C. modulation input at 52, 54 thereby producing pulses of amplitude and polarity corresponding to the D.C. input, which are applied to the oscillator to correspondingly modulate its amplitude about a mean value. (The positive input to the chopper across resistors 63, 61 ensures that, when transistor 59 is conductive, the output voltage at the junction of resistor 56 and capacitor 57 is zero when the D.C. modulation input is zero.) The pulses may be applied to the transistor oscillator base electrode 20 after amplifying at transistor 5. The oscillations may then be rectified and a constant D.C. voltage corresponding to the oscillator mean output deducted, thereby forming a D.C. linear amplifier of the D.C. input. This may be applied to a transistor phase inverter circuit, e.g. paraphase amplifier or long tailed pair, to give a push-pull D.C. output applied to a D.C. servomotor adjusting a selfbalancing potentiometer connected across a D.C. source of opposite polarity to the input D.C. so that the sum of the latter and the potentiometer output is applied to the chopper and is maintained zero by the servo loop. A further potentiometer for the D.C. input enables a range of D.C. inputs to be handled. The self-balancing potentiometer slider may be connected to a recorder for recording variable D.C. inputs. The chopper switching input may also be connected by a capacitor to the selfbalancing potentiometer tapping or to the motor D.C. control voltage to introduce an anti-hunting voltage proportional to the speed or acceleration of the motor. In addition to the potentiometer the motor may drive a pointer over a scale through a friction drive, to this end being mounted on a spring biased counterweighted arm so that its spindle bears against a friction disc driving the pointer.
