Abstract: 203,329. Roucka, E. Sept. 1, 1922, [Convention date]. Tell-tale apparatus.-In receiving apparatus for periodically measuring physical value by electric impulses, the position of which in a time interval forms a measure of the value, an auxiliary force such as the tension of a spring is varied periodically and is caused by an impulseto transmit its momentary value to an indicating. &c. part. The Figure shows a system in which indications as to variations of fluid flow are transmitted during regular intervals of time determined by the rotating cam 182 and are recorded by sychronous apparatus at the receiver. Receiving apparatus. A cam 6, driven by a. sychronous motor 2, oscillates the arm to vary continuously the tension in the springs 44, 46, 58, 60 and oscillate the shaft 32. The end of the spring 60 is connected to an arm 56 carried by a sleeve 62 loose on the shaft. The sleeve 62. carries a brake segment 66 normally engaged by a strip 108. The strip 108 is held in engagement with the segment 66 against the action of a resilient strip 112, with which it is connected. by a rod 114, by a lug 128 on a lever 136 which carries the armature 142 of electromagnets 144. The shaft 32 carries a brake segment 68 which cooperates with a strip 110. When an impulse occurs, the electromagnets 144 attract the armature 142 and the strip 110 is moved into engagement with the brake segment 68 to hole it against movement, the segment 66 being simultaneously released to allow the sleeve 62 to oscillate under the tension of the springs 44, 46, 58, 60 into a position corresponding to the position of the segment 68 when its movement was interrupted. The link 120 is constantly oscillated by the cam 6, and returns the strips 108, 110 to their normal position at the beginning of the next interval of time. An indicating arm 76 is operated through a spring 70 by an arm 64 on the sleeve 62 and carries a pointer 82 movable over a scale 84 of length corresponding to a time interval. The spring 70 allows the points 82 to assume its indicating position slowly. For recording the positions of the pointer 82, a pen- 86 movable over a travelling record strip 92 is provided. Transmitting apparatus. Upon a difference of pressure at opposite sides of an orifice 152 in a pipe 150 through which a fluid flows, a fluid in receptacles 156, 158 is displaced so as to affect the weight of the receptacle 158 which is carried on a pivoted lever 164. The tension of spring 172 is varied periodically by a cam 182 driven by a synchronous motor 186. The lever 164 carries a contact which co-operates with a resilient strip 170 and when the weight of the vessel 158 balances the force of the spring 172 an impulse is transmitted to the electromagnet 144. A switch 190 prevents the electric impulses from being produced except during the correct intervals of time.

Liquids are purified and freed from microorganisms by spark or arc discharge of pulsating current of high voltage generated by charging a capacitor from a D.C. source and discharging it through electrodes immersed in the liquid, the pulses and voltage being sufficient to provide a total energy of 0.05 to 5 kWh. per cubic metre of liquid. The process may be applied to waste waters, polluted well water and may be first filtered to remove coarse impurities. Salts and organic impurities flocculated by the electric discharge are filtered off. For example, a conduit for polluted water 2, includes a chamber 12, provided with electrodes 4, 5, one of which is movably controlled by an electromagnet 13. In operation, the electrodes are initially in contact and are separated by pulses from a capacitor charged at 60,000 volts. The discharge spark passes and the electrodes then move into contact until the next electric pulse.

Abstract: 644,874. Engine stop-gear. CLARK, G. M. (Auto Research Corporation). Aug. 8, 1947, No. 21875. (A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 8, 1947.) [Class 122(iv)] [Also in Groups XXI, XXXIV and XXXVII] In a force-feed lubricating system comprising a central pump, a central reservoir and a branched conduit system having a plurality of flow metering outlets to bearings to be lubricated, a control or signal system is provided to indicate exhaustion of lubricant in the reservoir or drop of pressure in the tubing system, the control or signal system being operated by an oscillating mercury switch. A float 61, Fig. 2, is secured to the lower end of a rod 58 within a reservoir 10, the upper end of the rod 58 being connected to a bracket 55 pivoted at 56 and carrying a mercury switch 42 comprising a glass bulb into which two contacts extend which are normally connected by a globule of mercury. In operation, when the level in the reservoir falls below a predetermined level, the mercury switch opens, thus operating a bell or light or stopping the machine. In a modification, Fig. 5, the mercury switch itself forms a float which is pivotally secured to a lug 79. In an arrangement in which the switch 42<SP>3</SP> is operated by lubricant pressure, Fig. 12, a spring-pressed plunger 131 having a collar 132 is constantly biassed in the direction of the arrow 135 by an arm 137 and spring 136. When the lubricant pressure is sufficient the plunger will be moved to the left, thus operating the switch and permitting operation of the machine. The switch may be arranged so that when it moves back to a horizontal position due to decrease in lubricant pressure the machine is stopped. The Specification as open to inspection under Sect. 91 includes an arrangement wherein a float 61<SP>5</SP>, Fig. 15 (Cancelled), maintains a knocker member 217 out of contact with a bell 218 when there is sufficient lubricant in the reservoir. The knocker is oscillated by a boss 203 on a rotating shaft 201. It includes also a further arrangement wherein warning is given or the machine is stopped when a bearing overheats due to lack of lubrication by means of a thermostatic device. The latter comprises a bi-metallic strip 260, Fig. 16 (Cancelled) secured to one terminal 262 and normally spaced from the other terminal 265. On overheating of the bearing, the end 270 contacts terminal 265, thus completing the circuit. The thermostatic device may be contained in a plug screwed into the bearing. This subjectmatter does not appear in the Specification as accepted.

Title: Process for the production of metals or metalloids or mixtures or alloys thereof in a very pure state
IPC: C01B33/06
Filed: 1959-06-25
Abstract: <PICT:0926362/III/1> B or Si or mixtures or alloys of these are produced by passing the corresponding halide, hydride or hydrogen-containing halide or mixture thereof in the gaseous or vaporous form through a fluidized bed of the element to be produced or an inert material heated to above the decomposition temperature. Inert or reducing gases or vapours may be passed in with the gaseous starting materials.  The Figure shows an apparatus in which an upflowing stream of gases or vapours from 2, preheated at 3, fluidizes a particulate bed contained between a and b.  The issuing gases pass out through filters 5 and 6 and a condenser 7, and a part or all of them may be recycled through a pump 12.  The element produced deposits on the particles of the fluidized bed until these fall and are discharged at 9.  Simultaneously fresh particles are formed in the bed and further material deposits on these. By increasing the velocity of the upflowing gases these fresh particles may be removed and collected at the filter 5.  Mixtures of elements may be produced by passing mixed gases into the bed and the particles produced may be alloyed if the bed temperature is correct.  The process may also be used for producing fine Si particles from by passing Si Cl4 or Si Br4 through a bed of coarse Si particles at above the decomposition temperature. The fluidized bed may be heated by electric induction or resistance heating or by periodically supplying a gas (e.g. H2 or HCl) which reacts exothermically with the bed material.

Abstract: 1345774 Wells &c ESSO PRODUCTION RESEARCH CO 19 April 1971 [16 Feb 1970] 21921/71 Heading E1F A method for the consolidation of a subterranean incompetent formation surrounding a well bore, comprises sequentially injecting into the formation at least two mutually reactive resin-forming components, of which one component is a curing agent, and permitting them to react therein to form a solid resin, one of the reactive components being injected through a first conduit which extends from the surface to an elevation in the well bore proximate to the formation, and the other of the reactive components being subsequently injected through a second conduit which extends to a similar level in the well. The first and second conduits may be provided by a tubing string and the casing-tubing annulus respectively or by parallel tubing strings. The first component may be a liquid thermosetting resin such as a phenol-formaldehyde type resin obtained by the reaction of an aldehyde with a low molecular weight hydroxy aryl compound, an epoxy resin or a furfuryl alcohol resin. The resin may be in the form of a solution. Many curing agents, particularly organic acids and amine bases are specified. An injection procedure is described in which the well is first killed by pumping salt water down the casing, a tubing string is run, the salt water is replaced by circulating diesel oil, and a curing agent solution is pumped through the casing-tubing annulus followed by diesel oil and halted a few feet above the lower end of the tubing. An epoxy resin solution is pumped down the tubing preceded by an ethylene glycol monobutyl ether pre-flush and followed by a diesel oil after-flush, and the resin solution and curing agent solution are sequentially displaced into the formation by pumping their respective diesel oil after-flushes. A separation ball may be inserted in the stream between the diesel oil and preflush and between the preflush and resin solution.

Abstract: 1,110,751. Stretching polyester cords. GOODYEAR TIRE & RUBBER CO. 25 May, 1965 [22 June, 1964], No. 22059/65. Heading B5B. [Also in Division D1] A polyester cord or fabric is subjected to a first treatment stage in which it is stretched by 2 to 10% for a period of 30 to 70 seconds at a temperature exceeding 440‹ F.; and a second treatment stage in which it is allowed to shrink by 30 to 50% of the amount by which it has been stretched, said shrinking taking place for a period of 30 to 70 seconds at a temperature at least 10‹ F. higher than the temperature of the first stage; and then maintaining the residual stretch while the cord is cooled. The cord may be polyethylene terephthalate. In Fig. 1 the fabric is withdrawn from storage roll 1 or 2, passed through a storage compensator 4 insuring a continuous flow, an adhesive container 6, a first warm-up oven 10, and thence through a drying oven 11 maintained at about 260‹ to 300‹ F. in which the adhesive is dried. The fabric, for its first stage of treatment, then passes through a third oven 12 maintained at 460‹ F., a chamber 17 at room temperature, and tension rolls 15. The tension rolls 15 cause the fabric in the oven 12 to stretch by 5%. The rolls 19 in chamber 17 are connected to the rolls 20 in the oven 12 so that the setting of the rolls 20 can be varied to predetermine the time of passage of the fabric through the oven 12. The fabric may pass through a second adhesive chamber 25. For its second stage of treatment the fabric passes through an oven 26 maintained at 470‹ F., each fabric portion being treated for substantially 53 seconds, this period being equal to the period in the oven 12. The fabric then passes to a cooling chamber 33 and tension rolls 28, the tension rolls 28 creating less tension than the tension rolls 15 so that the fabric in the oven 26 can shrink. The treated fabric passes to a wind-up roll 40 via a storage compensator 35. The cord or fabric may be used for tyre reinforcing.

Abstract: 1,262,544. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 1 May, 1969 [10 May, 1968], No. 22234/69. Heading H1K. An ohmic contact to a zone of a semi-conductor device or integrated circuit comprises a layer of rhenium overlaid by a layer of high conductivity metal. The integrated circuit of Fig. 5 is formed from a P-type Si wafer by planar diffusion steps to form first the N-type zones 31, 35, then the P zones 32, 34, thirdly the N+ collector contact and emitter zones 36, 33 and finally the boron diffused P + base contact zone 38 and resistance contact zones 39, 40. On the appropriately apertured oxide layer 37 rhenium, gold or copper, and rhenium layers are successively deposited by evaporation or R.F. sputtering and shaped by photoresist and etching steps, using specified etchants, to provide the contacts and interconnections shown. After deposition of a further oxide layer 43 apertures are etched to expose certain of the interconnections and contacts as at X, where rhenium is then removed and replaced by superposed layers of rhenium and gold which are etched to form a desired interconnection pattern as before. Ohmic contacts with expanded bonding pads can similarly be provided on passivated planar transistors in a common slice from which single devices can be divided. In this case platinum may first be deposited on the contact areas and heated to form platinum silicide prior to deposition of rhenium and gold layers. Contact resistance is lowest when the contact areas are heavily P or N doped (>10<SP>21</SP> atoms/c.c.) or precoated with aluminium.
