Title: Improvements in and relating to revolution counters
IPC: G06M1/06
Filed: 1923-06-21
Abstract: 214,127. British Thomson-Houston Co., Ltd., (General Electric Co.). June 21, 1923. Transmitting actuation to counters actuated by revolving-mechanism. - The driven spindle is formed in two parts adapted to be connected by an electromagnetic clutch so that the counting- mechanism may be started without loss of time. The spindles 16, 17 are mounted in bearings 13, 14, 15 on the frame 10, axial movement being prevented by collars 18. Splined to the spindle 16, on which is placed the contact tip 19, is a clutch collar 20. The other clutch member 21 is fixed on the spindle 17. A worm 22 on the spindle 17 meshes with a worm wheel on a shaft 24 to which a graduated indicating dial 25 is secured by a spring washer 26 and thumb nut 27. The dial is read against a vernier 28. The clutch collar 20 is actuated by a fork 32 secured to the armature 31 of an electromagnet 30. The clutch is biased to the closed position by a spring 33, and is opened when the coil 30 is energized. When it is desired to count the drift revolutions made by an electric motor after the current has been cut off, the electromagnet of the counter may be shunted across the terminals of the motor with a suitable resistance in circuit. The clutch of the counter will then be operated when the main switch of the motor is opened. The counter may be mounted adjacent to the end of the revolving element.

Title: Improvements in and relating to electrical switches of the gas blast type
IPC: H01H33/76
Filed: 1939-06-01
Abstract: 533,008. Gas-blast switches ; arc-rupturing in switches. FARRER, S., PAILIN, G., and FERGUSON PAILIN, Ltd. June 1, 1939, No. 16170. [Class 38 (v)] When the movable contact rod 4 is moved to open the circuit, the arc drawn between movable contact 7 thereon and a fixed annular contact 6 generates a pressure that acts through a passage 11 on the arc subsequently or simultaneously formed between the end 5 of the rod 4 and the contact 3, and drives it into the chute through openings 12, 14. If desired, the cross-passage 13 and 15 (if provided) leading to the openings 12. 14, may be obstructed by the contact so as to enable adequate pressure to be developed. An insulating sleeve 9, the member 10 containing the passage 11 and a member 20 are of gasevolving material such as carbamide resins, vulcanite, fibre, ebonite, aminoplasts, halogenated diphenyl ketones or dibenzyls and methyl methacrylate. The shoot is divided into two by a partition 18 and is further sub-divided by partitions 19, on which abut electrodes 21 connected to tappings of a resistance (not shown) connected to the contact 3, the arc-sections being thereby short-circuited in turn and the current reduced in the remainder of the arc. Spaced, parallel, metal plates 17 are also located in the shoot. In Fig. 3, a single arc is drawn between the movable and fixed contacts 33, 30 the arcchamber being largely filled by a cylindrical mass 36 of gas-evolving material through which the contact 33 passes. The mass 36 contains two sets each of, for example, eight radial passages 37. The movable contact obstructs the crosspassage 39 so building up the gas-pressure until the passage is opened, whereupon a blast occurs through the parallel passage 38 and is deflected into passage 39 and across the arc-portions at the latter. Gas-production may be increased by an insulating rod 45 extending into an axial bore 44 in the contact 33, and electrodes connected to a resistance may be fitted as in Fig. 1. The contacts 38 may be of square cross-section so as to reduce gas-leakage. Such a structure may be combined with an isolating break in a single unit resembling an oil circuit-breaker, the " head" " of which supports lead-in, bushings carrying the arcing-chamber and a fixed isolating contact. The contact 33 and movable isolating contact are mounted at opposite ends of a bridge-member, and the "head" is supported by a framework enclosed by side-plates, Fig. 8 (not shown). In a modification of Fig. 1, the fixed contact 3 is replaced by a nozzle-contact, between which and contact 6 are spaced annular insulating discs having perforations, and a block of gas-evolving material traversed by the movable contact and having axial passages coinciding with the disc-perforations. The spaces between the discs provide radially-directed lateral blasts as they are uncovered by the movable contact, Fig. 7 (not shown).

Title: Rim spacers for vehicle dual-wheels
Inventor: WALTHER WILLIAM DEAN
IPC: B60B11/06
Filed: 1970-04-06
Abstract: 1,236,899. Dual wheels. DAYTON STEEL FOUNDRY CO. 6 April, 1970 [2 July, 1969], No. 16210/70 Heading B7C. An annular dual-wheel rim spacer 10-1 has radially outwardly directed edges 31 and a circumferentially extending medial portion between said edges having one or more annular flexible ribs axially elastically compressible, so that in use when the spacer is located with its edges between and contacting the inner and outer rims of a dual-wheel and rim clamping means on the wheel are tightened, the spacer deforms elastically and maintains the rims mutually spaced apart axially of the wheel. The inner rim 11 is located on the wheel 14 by a conical flange 20, at 28 degrees to the axis, engaging a complimentary conical surface 19 on the wheel, while the outer rim 12 is maintained on the wheel by an annular clamp lug 16 which slidingly engages a belly surface 15 of the wheel to bear against a conical mounting surface 21 on the rim 12. The two rims are separated by the spacer 10-1 which has annular ribs 32 formed in its medial portion and is carried by the belly surface 15. Tightening a nut 17 on a screw 18 attached to the wheel 14 causes the nut to bear against the lug 16 to move the outer rim 12 towards the inner rim 11 and compress the spacer 10-1 by elastically deforming the ribs 32. The spacer can be made from sheet or tubular steel 0.0625 inch, or 0.125 inch thickness and the nut tightened to a torque of 190 footpounds. An alternative spacer (Figs. 3 and 4, not shown) has one rib (52) formed by two intersecting conical surfaces.

Title: Improved means for adding insoluble or granular solid to liquid
IPC: C02F1/68
Filed: 1948-06-16
Abstract: 658,521. Mixing fluids in flow in proportionate quantities. PATERSON ENGINEERING CO., Ltd., and BAILY, E. W. June 16, 1948, No. 16240. [Class 86] Apparatus for entraining filter aid or other granular solid material into a liquid comprises a tank 10 provided with a tapering base in which an ejector 21 is fitted the ejector nozzle being surrounded by an annular space to which a regulatable proportion of the supply to the jet can be byepassed. The ejector is connected to a point in the main 40 at a point upstream of a cock or flow restricting device 48, and a pipe 25 opens directly above the ejector 21 and is connected to the main 40 downstream of the cock'48. Filter aid material is placed in the tank 10 together with some of the liquid flowing in the main 40, and with the cock 48 partially closed, the flowing liquid will pass through the ejector and entrain a proportionate amount of filter aid material. By means of a pipe 30, connected to the top of the tank 10 and to a point up-stream of the ejector the pressure in the closed tank is prevented from falling. The proportions of flowing liquid and filter aid may be controlled by cocks 34, 36, 37. Opening the branch controlled by cock 37 allows flowing liquid to enter into the ejector space and thus reduces the amount of filter aid entrained; closing this branch and opening branch 34 ensures that the filter aid material is kept agitated and increases the feed rate. Similarly, cock 36 controls the feed rate of filter aid. A modification is described in which the pipe 25 is vertical and opens into the top of the tank 10 where the mixture 01 liquid and filter aid is drawn off.

Title: Improvements in electrical systems of remote supervision
IPC: H02J13/00
Filed: 1950-06-29
Abstract: 678,770. Electric selective signalling systems. GENERAL ELECTRIC CO., Ltd., and POPE, B. W. April 26, 1951. [June 29, 1950] No. 16266/50. Class 40 (i). Apparatus for indicating two kinds of alarm, e.g. permanent or temporary, from a number of apparatus groups at a power station comprises synchronously stepped switches at the transmitter and receiver, two contacts in each of two switchbanks associated with each alarm point, and means for transmitting a characteristic signal, e.g. a positive potential, through said contacts to indicate at the receiver the characteristic alarm at the transmitter and appropriate apparatus group. A permanent alarm is produced by the closure of switch P, Fig. 1, associated with one particular apparatus group, causing energization of relay PR, which locks itself, and de-energizes relay ST, to break the circuit through stepping magnets S and T, Fig. 2, at the receiver, subsequently re-energized by the operation of slow-to-operate relay PS. Thus, the switch contacts S1-S4, T1-T3 step forward one step, and continue stepping in synchronism for one cycle through S4 and impulsing contact IP.. At contact 6, relay PG is energized through Sl and locks itself, while S2 transmits a positive potential to the receiver, where relays Q, QA are operated and lock themselves, contact QA2 applying an intermittent voltage to lamp LA via leads FS, FL. T1 applies the necessary positive potential to IP to cause the stepping magnets S, T to proceed one step to the seventh contact, when relay PA is energized via Sl, and S2 again sends a positive potential to T2 to operate relays QB, QC in succession, and again T1 supplies the positive potential to IP to cause the magnets S, T to complete the stepping cycle. Thus, the operation of the permanent alarm P causes all the relays to be energized and lamp LA to light intermittently. The signal is acknowledged at the receiver by the operation of key AK, when relay QA is released and lamp LA is continuously lit. The release of permanent alarm switch P initiates another stepping cycle, when all the relays are returned to normal and lamp LA is extinguished. A temporary alarm, produced by the temporary closing of switch F results in a signal from S2 at the sixth contact but not on the seventh. Thus, at the sixth contact the lamp LA is intermittently lit, but at contact 7 relays QB, QC are not operated, so that the operation of key AK causes lamps LA and RA to light steadily, the circuit being returned to normal by the operation of key RF. The signals sent from the transmitter to the receiver may be positive potentials as above, or any other method of signalling, e.g. pulses or V.F. signals.

Title: Improvements in contact converters for the production of sulphur trioxide
IPC: C01B17/80
Filed: 1957-05-22
Abstract: <PICT:0841636/III/1> In a method for the production of sulphur trioxide wherein sulphur dioxide and oxygen-containing gases are passed through a vertical series of perforated trays containing catalyst, heat exchangers are arranged after and between the catalyst trays, some of the heat exchangers constituting pre-heaters for the reaction gases which are passed internally therethrough on their way to the first catalyst tray, and through the other heat exchangers is passed a heat absorbing medium.  A mixture of sulphur dioxide and oxygen-containing gases is fed from a conduit 26 through a heat exchanger 11, a conduit 28, a heat exchanger 9, a conduit 29, a heat exchanger 8, a conduit 30, a heat exchanger 7 and a conduit 31, to heat the gas mixture to a suitable temperature, which is controlled by shunting some of the gas past the heat exchangers via conduits 34 and 35 and portions 36 and 37 of conduits 30 and 31.  The gases then pass down through catalyser units 1, 2, 3 and 4, comprising beds of catalyst on perforated plates, where the sulphur dioxide is partly oxidized to sulphur trioxide with evolution of heat which is removed by heat exchangers 7, 8 and 9. After catalyzer unit 4 the gases flow past a heat exchanger 12, through a catalyzer unit 5, and past a heat exchanger 13 and heat exchanger 11, and leave by an outlet 24.  Steam is passed from a line 18 through heat exchangers 12 and 13, being controlled by valves 57 and 60, to absorb heat generated in catalyzer units 4 and 5, and super-heated steam is removed by a line 19.  The operation is commenced by first blowing cold, dry air from a pump 44 through the catalyzer units and heat exchangers, then the circulating air is heated by means of steam in the heat exchangers 12 and 13, followed by heating the preheated air in an electrical heating device 48.  Sulphur dioxide is then fed into the circulating heated air through a valve 20 to start the reaction, which is continued as above.

Abstract: 946,515. Magnetic compositions. AMPEX CORPORATION. April 30, 1962 [May 26, 1961], No. 16501/62. Heading H1H. A dense magnetic ferrite body is produced by sintering a mixture of metal oxides to form a body, vacuum impregnating this body with a salt solution which decomposes on heating to yield the oxides of this same ferrite in the correct proportion and reheating the impregnated body to effect this decomposition and to sinter the oxides so formed to form the ferrite in the interstices of the main ferrite body. The ferrite body may be NiZn, NiCuZn, ZnMn, or NiMg ferrite and is formed by grinding the metal oxides, mixing with resin and lubricant pressing under 5-8 tons/sq. inch, heating to 400‹ C. to decompose the binder, and sintering at 800-1100‹ C. Impregnating takes place by immersion in an appropriate mixture of salt solutions (preferably sulphates) under a high vacuum for half an hour. The body is then sintered at temperatures up to 1400‹ C. Cooling, which depends on the ferrite, may be in air or N 2 . Complex heating schedules are disclosed for both the sintering steps.
