Title: Improvements in or relating to electrical measuring, indicating, recording, controlling or like apparatus
IPC: G01R17/00
Filed: 1946-04-12
Abstract: 621,388. Electric indicating and controlling systems. ELECTROFLO METERS CO., Ltd., and TABOR, H. April 12, 1946, No. 11293. [Class 37] [Also in Group XXXVIII] In electrical measuring, indicating, recording, controlling or like apparatus which is automatically rebalanced after variations of the unknown quantity, accuracy is maintained by periodical standardization of the apparatus in comparison with the potential of a standard cell, the apparatus being adjusted to the standardizing condition by an electromagnet energized from the same source as supplies driving current to the apparatus, so that on failure of current when in the standardizing condition the apparatus is automatically restored to the normal condition, thus avoiding discharge of the standard cell. In a device comprising an automatically balanced slidewire potentiometer in the manner described in Specification 526,057, [Group XXXVIII], the potentiometer slidewire is supplied with current from a battery through a series resistance including a rheostat consisting of a pair of serially connected resistance wires 4, 41 (Fig. 1) contacted by sliders 5, 5<SP>1</SP>, and mounted on the periphery of a drum 2 revolved in a fork 6 by a gear-wheel 7 engageable by a gear-wheel 71 driven by the balance restoring mechanism of the apparatus (not shown). A solenoid 10 has a plunger 10<SP>1</SP>, the ends of which respectively abut on an arm 9 rocking the fork about a shaft 8<SP>1</SP>, and on the centre of three spring contact leaves 11, 12, 13 forming switch 1, shown as S in the potentiometer circuit diagram (Fig. 2). In normal operation, the solenoid is not energized, gear-wheels 7 and 7<SP>1</SP> are disengaged, and an E.M.F. is tapped from the potentiometer slidewire C, which is supplied with current from battery B through rheostat R1, constituted by wires 4, 4<SP>1</SP>. The potentiometer E.M.F. is automatically balanced against the E.M.F. of a thermocouple TC in a galvanometer or other detecting device G controlling the self-balancing mechanism. The apparatus is periodically standardized by energizing the solenoid 10 from the current supply driving the apparatus as a whole, under control of a switch operated manually, or automatically by a cam driven by a motor forming part of the apparatus. The solenoid plunger then moves to the right, engaging gear-wheels 7 and 7<SP>1</SP> and operates the switch 1, shunting the galvanometer with resistance R3. The E.M.F. of standard cell A is automatically balanced against the voltage drop across resistance R2, in the potentiometer circuit, by adjustment of R1 when the current in the slide wire assumes the standardized value for accurate measurement. On failure of the current supply, the solenoid is de-energized and the apparatus is switched back to its normal measuring function.

Title: Apparatus for drying compressed gases
IPC: B01D53/04
Filed: 1973-03-09
Abstract: 1422244 Drying air CHAUMECA 9 March 1973 [10 March 1972] 11532/73 Heading B1L Air delivered by a compressor 1 is dried by passage through a first unit 3 comprising a heat exchanger 9 and a cooler 8, and a second unit 6 comprising a cooler 19 and moisture adsorbent driers 16, 17 provided with valves 15, 18, 21-24 operable to allow use of one drier while the other is being regenerated. With the valves 15, 18 and a valve 11 in the position shown, hot and humid oil entrained compressed air flows in turn through the cooler 8, an oil remover 4, a coil 12 in the exchanger 9 and thence via a non-operative heater 28 to the second unit 6 where it passes through the drier 16 to an outlet pipe 7. When the adsorbent in the drier 16 becomes saturated the valves II and 18 are changed over. This directs the compressor output through the heat exchanger 9 where the heat of compression is given up, the air then passing through the cooler 8 and oil remover 4 before recovering the heat of compression by passage through the coil 12. The temperature of the air is further raised by passage through the now operative heater 28. From the heater 28 the air flows through the drier 16 to effect its regeneration and then via the non-return valve 24, cooler 19, non-return valve 21 and the other drier 17 to the outlet 7. After regeneration the drier 16 is cooled. This is effected by de-activating the heater 28 and returning the valve 11 to its position shown, whereby cool air enters the drier 16. Next the valve 15 is changed over so that the drier 16 is cut out and the drier 17 is used alone. While the drier 17 is in use, the drier 16 is further cooled by being in a closed circuit with the cooler 19 and the non-return valves 22, 24. Regeneration of the drier 17 is accomplished in an analogous fashion when required. Thermostats 25, 26 are provided. Another embodiment Figs. 1-6 (not shown) differs in that the heater 28 and thermostats 25, 26 are omitted and the valves are replaced by four, four-way valves.

Title: Olefin disproportionation
Inventor: MARSHECK ROBERT MILTON
IPC: C07C6/04
Filed: 1966-03-16
Abstract: 1,128,091. Disproportionating olefins. PHILLIPS PETROLEUM CO. 16 March, 1966, No. 11642/66. Heading C5E. In an olefin disproportionation system a feed olefin is converted catalytically into lower and higher olefins, the higher olefin then being converted in a separate zone into the feed olefin, which is recycled, and a still higher olefin. Fig. 1 shows such a system, in which zones C, E, G, I, K, M and O are used for disproportionating propylene-nonene respectively, and fractionating columns A, B, D, F, H, J, L and N each distil an olefin mixture to produce pure ethylene to nonene respectively overhead and a bottoms product which passes to the next column. Values 1, 31 &c. allow for removal of any desired pure olefin or for introduction of supplemental feed to a disproportionation zone. From column A pure ethylene is collected overhead and may be used as such or dimerized or polymerized in reactor 50 to give higher olefins which are returned to the system. The bottoms product from column N is fractionated in column P to give a C 10-16  olefin fraction and a higher olefin fraction, either or both of which may be used as such or cracked in reactors 44 and 46 to give lower olefins which are returned to the system. Any olefin or mixture of olefins may be used as feed for the process, but in the process described propylene is used. Conventional disproportionation catalysts are used in the disproportionation zones, e.g. cobalt molybdate on alumina, tungsten oxide on silica, or tungsten or molybdenum hexacarbonyls on silica, alumina, or silica/alumina.

Abstract: 775,304. Supplying liquid fuel to burners. QUEEN STOVE WORKS, Inc. April 21, 1954, No. 11570/54. Class 75(1) In a mantle lantern liquid fuel is supplied from a tank 21 to a vaporizing tube 42 through a tube 37 extending upwardly from the base of the tank 21 and having a transverse orifice 38 (not shown) above and adjacent the base of the tank and of' a cross-section , substantially smaller than that of the bore of the tube 37, a tube 41 containing a cut-off valve 40 connecting the tube 37 with the vaporizing tube 42, and air under pressure being supplied to the space above the fuel in the tank by a pump 32. At the start air is pumped into the tank 21 and the valve 40 is opened so that air passes through the tube 37 and receives fuel through the orifice 38, the fuel-air mixture passing through the vaporizer 42 and mixing tube 44 to the burner 46 where it is ignited. After the vaporizer 42 has become heated liquid fuel will back up into the tube 37 to prevent the passage of compressed air so that fuel only is supplied to the vaporizer 42 through the orifice 38. When the burner is operating it is not necessary to pump more air into the tank 21, and the valve 40 need be adjusted only at starting. A metal filter screen 39 surrounds the part of the tube 37 in which the orifice 38 is provided.

Title: Process for maintenance of the vitamins in the preservation of vegetable materials
IPC: A23B7/022
Filed: 1930-04-12
Abstract: In a process for preserving vegetable materials, e.g. lucerne, by drying, in which the vitamin content of the materials is maintained, the materials are treated with an acid or acids and a salt or salts and are then dried.  When the materials contain acid this may be used in part substitute for the acid to be added.  The acid and salts may be used simultaneously or in succession, and care is taken that all the material comes into contact therewith. During plasmolysis the solution should have a pH value of 2-6.  In an example, freshly harvested lucerne is immersed in or sprinkled with a solution containing phosphoric acid and common salt, the material being then left for 15 mins. for plasmolysis to take place.  The material is next dried by treatment for about 2 hours with air currents at about 175 DEG  F. until the moisture content is reduced below 10 per cent, and may then be stored.ALSO:In a process for preserving vegetable materials by drying, in which the vitamin content of the materials is maintained, the materials are treated with an acid or acids and a salt or salts until plasmolysis is attained and are then dried.

Abstract: 812,263. Cap spinning &c. machines; yarn package supports. PRINCE-SMITH & STELLS Ltd. April 18, 1957 [April 18, 1956], No. 11780/56. Addition to 794,114. Classes 120(2) and. 120(3) A cap spinning or twisting machine has spindle units adapted to accommodate extensible bobbins as described in the parent Specification. The outer member 19 of each extensible bobbin is carried by a short hollow spindle mounted on a rail 2 and splined with a hollow plunger 5 that carries the inner member 18 of the bobbin and is mounted on a rail 8. A dead spindle 27 supports the cap 31. As described in the parent Specification the rails 2, 8 may be retracted by a chain 21. An alternative form of builder mechanism is driven from a motor 41, Fig. 6,, through a clutch 44, gearing 42f, 42k and worm 421, the latter driving a heart cam 43a. By further worm gearing, drive is transmitted to a shaft 51 and a worm 51a that rotates a chain sprocket 53 around which is wrapped a chain 53a connected through sprockets and a further chain to the rail 2 for the gradual lowering of the latter. Superimposed on the lowering motion is a reciprocatory motion derived from the heart cam 43a through a sliding carriage 50. After the rail 2 has been lowered by the length of the member 19 (Fig. 5), the rail 8 has a lowering and reciprocatory motion imparted to it through a cam 45 and lever 52. In addition to the builder motion, the motor 41 drives the drawing rollers 30a through the clutch 44 and gearing 42f and 33a. In an alternative form, axial reciprocation may be imparted to the dead spindle.

Filed: 1976-03-24
Abstract: 1515245 Testing integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 24 March 1976 [29 April 1975] 11811/76 Heading G1U A logic unit to be tested has a counter connected to each output line to determine the time of response of each output to an input stimulus. The counter and associated logic is as shown in Fig. 2 (not shown). A SET UP pulse via AND gate 20 sets bi-stable 22 to logic 'one', if the unit under test (UUT) output 12 is also 'one', otherwise it remains 'zero'. Thus, exclusive OR gate 24 indicates equivalence, providing a first enabling signal to AND gate 26. At a BEGIN COUNT signal, which also provides the input stimulust to UUT, a second enable signal passes to AND gate 26 which thus allows clockpulses into counter 30 until the output 12 changes resulting in a 'zero' from exclusive -OR 24 which disables AND-gate 26. A RESET pulse returns latches 22, 28 and the counter 30 to zero, for further measurements. Display 16 forms part of a multi-path display for all UUT outputs and may be a single sweep delay oscilloscope. In the Fig. 4 (not shown) embodiment, the AND-gate 26 output feeds an integrating capacitor and digital voltmeter. The capacitor is discharged by the RESET pulse via a monostable and AND-gate.
