Patent GB-472916-A (GB)
Title: Improvements in the control of electric winches
IPC: B66C13/24
Filed: 1936-04-04
Abstract: 472,916. Control of D.C. motors. SCOTT, W. H. April 4, 1936, No. 10024. [Class 38 (iii)] Controlling means for electric winches comprise a switch operable by a mechanical brake to bring about a change in the circuit conditions to suit the slowing down of the motor by the brake, in combination with a diverter resistance which is automatically connected across the motor armature as the mechanical brake is applied, while bringing a main resistance into circuit. The Figure shows a step-up main resistance 3, which may be the usual starting resistance, in series with the field winding 2 and the armature 1. The diverter resistance is indicated at 7, and is adapted to be thrown in or out by a relay switch 8 the control coil of which is shown at 9. The contacts 4 of the resistance 3 are operated by coils 5 shown in series with one another, and with a master controller 6 and the'coil 9 , which controller 6 and coil 9 have a brake switch 11 connected across them. Any suitable mechanical connection is provided between the switch 11 and the foot brake lever, so that while the brake is " off " the switch 11 is closed, and when the brake is applied, the switch 11 is opened. The controller 6 is a switch which, in the particular arrangement shown, effects energization of the first coil 5 while short-circuiting the others, and then breaks the short-circuit of each of the other coils 5 in turn, thus closing the contacts 4 in succession to cut out the resistance 3 gradually. Alternatively the switch 6 may allow the contacts 4 to re-establish the full resistance 3 when the first step has been passed, and to connect the diverter resistance 7 across the armature 1 instead of interrupting the controlling circuit. To present a " flash-over " occurring at the armature owing to a too high speed of the armature existing when the resistance 7 is switched in, the diverter relay 8 is prevented from moving by a lock-out means consisting of a switch-arm tail-piece 12 which is attracted by an electromagnet 13 connected across the armature, preferably through a ballast resistance 14. While the voltage across the armature is above a given value, the switch 8 cannot close, and the speed of the motor has to be reduced initially solely by the mechanical brake. The contact of the switch 11 may, however, be arranged to allow the diverter resistance circuit to close when the brake lever is only partly operated.

Title: Improvements in or relating to magnetic materials

Abstract: 696,216. Magnetic compositions.PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 25, 1950 [April 28, 1949], No. 10153/50. Class 38 (ii).

Air under pressure also is admitted above the sand 16 by a pipe 27 leading from the chamber through a check valve 27<a> and a gate valve 28, the valves 28, 31 normally being so adjusted that the pressure in the mixing chamber substantially balances the pressure due to the air in the reservoir together with that due to the weight of the sand. The reservoir is closed by a cover 33 in which is a valve 35; this valve is normally held closed, but may be opened to allow reserve sand from the cover to enter the reservoir, by a rod 36 moved by a piston 37 in a cylinder 38, air being admitted to one or the other end of the cylinder through pipes 39, 40 as the valve 23 is operated. The mixing chamber 18 has therein a sleeve 49 held in position by a cover 50 and shoulders 47, 48, and the sand passes into the chamber through a port 52 having its end walls inclined in the direction of the blast, the effective size of the port being adjustable by means of an adjustable gate 57. The mixing chamber is divided horizontally into two passages 55<a>, 55<b> by a removable baffle plate 55 carried by the sleeve 49. The sand and air pass from the mixing chamber to a concentrating chamber 20 and thence to a nozzle.

Title: Improvements in or relating to voltage regulator circuits for direct voltage
IPC: G05F1/607
Filed: 1949-04-20
Abstract: 666,078. Automatic voltage regulation. RADIO CORPORATION OF AMERICA. April 20, 1949 [April 24, 1948], No. 10483/49. Class 38 (iv). In a system for automatically regulating a low direct voltage across a variable load, the load is connected in series with a dropping resistance across a source of higher voltage stabilized by a shunt-connected constant voltage-drop tube, and a variable resistance, a control element of which is supplied with a selected fraction of the voltage across the constant voltage-drop tube, shunts the load. In the Figure, a low D.C. voltage, negative with respect to earth, e.g. for amplifier grid bias, is developed across a load 18 in series with a cropping resistor 17 across the output of a fullwave rectifier 1, the higher voltage of which is stabilized by a constant voltage drop tube 15, e.g. of the cold cathode glow discharge type. The voltage across resistor 17 is applied as negative grid bias to a triode 20 in shunt with the load so that variations of anode current compensate for variations of load current, thereby maintaining a constant voltage across the load. Positive bias for triode 20 is derived from a potentiometer 24 across tube 15 the setting of which determines the load voltage. A resistor 16 may or may not be necessary to limit the current through tube 15.

Title: Process for cracking hydrocarbons and a combination fluid solids reactor and thermal cracking unit
IPC: C10G9/32
Filed: 1957-04-01
Abstract: <PICT:0803104/III/1> Heavy residual petroleum stock is cracked by contacting it with a fluidized bed of hot solid particles to crack and to convert at least part of the stock to vapours, the vapours comprising cracked and vaporized stock, removing the vapours from the bed, through a disperse phase above the bed, to a recovery zone where a gas oil is recovered, thermally cracking a feed comprising the gas oil and passing the hot thermally-cracked products into the dispersed phase.  In a preferred embodiment, a heavy residual petroleum stock is fed to a system through an inlet line 21, a surge drum 23 and a line 29 into a fluidized bed of solids such as finely divided petroleum coke preheated to 900-1150 DEG  F. before coming to a reactor 11.  As fast as the feed is converted, the vapours pass through the interface between the bed and the disperse zone above it as indicated at 31.  The vapours pass into a scrubbing unit 39 and are fractionated in a tower 43 into coker naphtha and gases.  A gas oil is taken off through line 47 and passes through a surge drum 91 and to a thermal cracking circuit 17 operating at 20-300 p.s.i.g. The outlet temperature from the cracking coil should be 950-1200 DEG F.  The thermally-cracked gas oil emerges from the furnace through line 121 and passes through one or more lines 123 and 125 into the dispese phase at the top of the reactor.  The thermally cracked vapours thus introduced into the disperse phase pass upwardly through the cyclone 33 and through its outlet 37 into the scrubber section 39 and fractionator 43 above it.
