Title: Improvements in or relating to arrangements for increasing the range of regulation of carbon column resistance regulators
IPC: H02P9/22
Filed: 1938-12-28
Abstract: 523,210. Compression resistances. BORMANN, O. Dec. 28, 1938, No. 37668. Convention date, Dec. 28, 1937. [Class 37] [Also in Group XXXV] A carbon pile resistance is divided into sections which can be connected in series or parallel to extend its range. An arrangement is shown for maintaining constant the voltage across a load 3 supplied by a generator 1. A carbon pile resistance 4 is divided into three parts which are simultaneously compressed by the armature 5 of an electromagnet excited by a coil 6, which is connected in parallel with the load 3 through a resistance 7. This resistance may be short-circuited by a switch 8 for varying the regulated voltage, e.g. for changing lamps from reduced to maximum luminosity. In the position shown the three sections of the resistance 4 are connected in parallel by switches 9, 10. Increase in voltage causes rotation of the armature 5 and consequent variation of the resistance 4. At the limit of its travel, contacts 15, 16 are connected, closing a circuit through a relay coil 17 which attracts an armature 20 and opens the contacts 9, 10, 11 and closes the contact 14, thereby connecting the section of the resistance 4 in series. At the other limit of the travel of the armature 5 contacts 12, 13 are connected and close a contact through the relay coil 18 which attracts the armature 20 and returns the contacts 9, 10, 11, 14 to the position shown. The resistance 4 may be subdivided into a greater number of sections in order that a greater number of resistance combinations may be obtained. In this case a step-by-step switching mechanism is moved in one direction by the coil 17 and in the other direction by the coil 18. External resistances may be connected in series with the resistance 4 and controlled by a relay.

Title: Apparatus for reproducing mechanical movements at a predetermined ratio
Inventor: HANCOCK LESLIE JOHN
IPC: B23K7/00
Filed: 1962-10-12
Abstract: 977,137. Lirikwork; toothed gearing. HANCOCK & CO. (ENGINEERS) Ltd. Oct. 14, 1963 [Oct. 12, 1962], No. 38734/62. Headings F2K and F2Q. [Also in Divisions B3 and G3] A mechanism for linking two movable members of a machine, particularly a burner carriage 17 and a tracing carriage 22 of an oxygen jet profile-cutting machine, such that one member 17 imparts movement to the other member 22 in a predetermined relationship as to speed and displacement, comprises a crosshead 28 on the burner carriage 17 engaging an inclined slide bar 27 such that horizontal movement of the burner carriage causes a vertical movement of the crosshead in dependence upon the inclination of the slide bar, and means 34 are provided to convert this vertical movement into a movement of the tracing carriage 22. The latter is movable along the same trasverse rails 20 as the burner carriage 17 and carries an electronic tracer 40 adapted to scan a scale drawing on a table 24. The transverse rails 20 are mounted on a main carriage 18 running along longitudinal rails 20. In operation the tracer 40 scans the scale drawing on table 24 and produces electric signals corresponding to any change in direction. These signals control two motors driving the main and burner carriages thereby causing the torch 15 to cut the workpiece 14 along a profile enlarged, e.g. ten times, over the movement of the tracer 40. The crosshead 28 on burner carriage 17 has a roller 33 engaging the inclined slide bar 27. A cable 34 or steel tape anchored at 35 passes over pulleys 30, 31 on carriage 17 and around pulley 32 on the crosshead. The cable is attached at 39 to the tracing carriage 22 and is kept taut by a spring or counterweight 37. Transverse movement of the burner carriage thus produces a variable loop in the cable dependent upon the inclination of the bar 27 and this provides a reduced scale follow-up movement of the tracing carriage. The inclination of bar 27 may be varied or may be reversed so that the carriages 17, 22 then move in opposite directions. Drawing table 24 is movable longitudinally along the rails 26 and is linked to the main carriage 18 by a rack 48 meshing with a pinion 47 on the same shaft as a second pinion 46 meshing with a vertical rack 44, Fig. 2, on a vertically movable crosshead 42 of the main carriage 18. Crosshead 42 has a roller 43 running along an inclined bar 41 whereby the follow up movement of the table 24 is dependent upon the inclination of the bar 41. The rollers 33, 43 may alternatively run along the upper surfaces of their respective bars and the crossheads 28, 42 may be arranged at an angle other than vertical.

Title: Centrifugal separator discharge control system
IPC: B04B1/14
Filed: 1972-08-21
Abstract: 1354810 Centrifugal separators SIGNAL OIL & GAS CO 21 Aug 1972 [30 Aug 1971] 38822/72 Heading B2P A centrifugal separator for separating a mixture of two fluids of different densities comprises means to sense the fluid pressure in the outlet 38 for the centrifugally separated lighter fluid, means to sense the fluid pressure in the separator inlet 44, and a valve 54 in the lighter fluid outlet 38 and operably connected to both sensing means to discharge separated lighter fluid from the separator when the sensed pressure of the lighter fluid exceeds a preselected value above the sensed inlet fluid pressure. The separator may be used for separating an oil-water mixture and comprises a perforateinner drum 12 within an imperforate outer drum 14 and spaced therefrom by radial septa 24 which divide the annular space between the drums into sectors 28. The interior of the inner drum 12 is likewise divided into sectors 32 by radial septa 30. Vanes 36 and 42 are provided between the ends of the inner and outer drums. The whole assembly is rotatably mounted in bearings 46, 50 and driven by a belt 52. The valve 54 is of the diaphragm type and is connected in the outlet 38 by a bearing and seal housing 53. A coil spring may be incorporated in the valve to bias it towards the open position. In operation, the oil water mixture fed through the inlet 44 is forced outwardly into the annular space between the drums 12 and 14 by the vanes 36. Water separated outwardly by centrifugal force in the annular space is directed by the vanes 42 out through the heavier fluid outlet 48. The oil flows inwardly through openings 16 in the iner drum 12 to form a cylinder of pure oil at the centre thereof and is directed to the lighter fluid outlet 38. The septa 24, 30 keep the fluid rotating at the same speed as the integral unit. As shown, one side of the diaphragm tending to open the valve 54 is subject to the pressure in the lighter fluid outlet and the other side tending to close the valve is subject to the pressure in inlet 44. The valve 54 will remain closed until there is sufficient accumulation of oil within the drum 12 to create a pressure greater than the pressure in inlet 44. In another embodiment, Figs. 4 and 5 (not shown), the lighter and heavier fluid outlets are at opposite ends of the separator which has a central, perforated hollow drive shaft through which the lighter fluid is discharged towards its outlet. The interior of both the inner and outer drums are divided by weir-type partitions so that separation occurs by stages in the annular space between the drums.

Title: Improvements in magnetic amplifiers
Inventor: TORREY ROBERT DUTILH
IPC: H03K3/45
Filed: 1956-12-28
Abstract: 853,409. Magnetic amplifiers. SPERRY RAND CORPORATION. Dec. 28, 1956, No. 39500/56. Class 40 (9). A core is pulsed over a positively-poled rectifier from a source of alternating square waveform during negative half-cycles of which the core may be reset from positive to negative remanence. If a positive half-cycle is not preceded by a reset the positive pulse encounters low impedance as the core is driven from positive remanence into positive saturation. At the end of the positive pulse the core may be driven negatively down its hysteresis loop away from full positive remanence by reverse conduction of the rectifier, by discharge of the rectifier due to diode enhancement, or by discharge of the distributed capacity of the core winding. To ensure that the core is held saturated and remains near full positive remanence a positive bias is applied to the core or the core is damped by a low-impedance winding. In Fig. 1 the positive half-cycles of a source 15 are applied to a load 16. Negative half-cycles of source 15 open a rectifier 18 to complete a circuit for a reset winding 11. A positive bias is provided by a potential V connected to the winding 13. With the load 16 in series with winding 13 output is produced in positive half-cycles not preceded by reset. In Fig. 3 a load 36 is connected in parallel with winding 33 driven from source 35 so that output is produced in positive half-cycles only if preceded by reset. In this arrangement the reset winding 31 is gated by a pulse source 39 with the waveform shown in Fig. 5 compared with the waveform of source 35. In Figs. 1 and 3 the bias may be applied to the reset winding, see Figs. 2 and 4, not shown, and the bias may be drawn from the negative halfcycles of the alternating square-wave supply, see Fig. 7, not shown. The circuit associated with the reset winding may be of low impedance to damp the core during negative half-cycles, see Fig. 6, not shown. Bias may be applied to the core by pulsing the reset winding at the beginning and for a fraction of each half-cycle, see Figs. 8 and 9, not shown. The load may be connected to a separate output winding and a separate bias winding be provided, see Fig. 10, not shown.

The crutch E is pivotally mounted on a lever D having rollers H<1> at its lower end engaging the slotted guides and rollers G<1> at its centre adapted to engage the ramps. A link J is centrally pivoted to the lever D and has at its lower end rollers I<2> running on guide surfaces A<1> of the frame. A parallel motion link F connects the crutch to the link J. A sleeve nut K is connected to the lower end of the link J. In operation by means of ratchet or other gearing W, the screw L engaging the nut K is rotated. The link J raises the lever D as the rollers G<1> ride up the ramps C and the rollers H<1> travel down the slotted guides. Continued rotation of the screw then causes the link J to further raise the lever D and crutch. In a modification the parallel motion links are anchored to a guide-plate mounted in an extension of the slot B.
