Title: System for measuring a variable impedance at a distance
IPC: G01K1/02
Filed: 1965-09-07
Abstract: 1,126,381. Measuring temperature electrically; resistance measurements. BUZZARDS CORP. Sept. 7, 1965 [Sept. 11, 1964; April 29, 1965], No. 38234/ 65. Headings GiN and G1U. Temperature at a remote location is measured by a thermistor 25 (Fig. 2) whose resistance is compared with that of an adjustable variable resistor 30. Each resistance 25, 30 is shunted by a diode 28, 34 respectively, poled in opposite directions, and connected in series to a constant current D. C. source 36 which is reversed at a regular rate, so that the voltage across the appropriate resistor in the half-cycle when its diode shunt is open-circuit is proportional to the value of the resistance. The voltages are composed in a differential amplifier, and a servomotor adjusts the standard resistor 30 until the difference is zero, simultaneously driving a recorder 44. Alternative methods of inter-connecting the thermistor 25 and adjustable resistor 30 are described Figs. 6a, 6b, (not shown). The system is described in relation to apparatus for determining the relationship between temperature and depth in a body of water, and comprises a probe released from a ship to record temperature against depth and optionally also velocity of sound as it falls through the water. The thermistor 25 is located in the nose of the probe, and connected to the ship by a single core cable 16, using the sea as the signal return path 22 between electrodes 18 on the probe and 20 on the ship. The resistances 23 of the cable and return path are common to the measurements in both half-cycles, and so do not affect accuracy. The rate of reversal of the applied D. C. is continuously reduced as the probe falls to keep the effect of the shunt capacity between the electrodes 18, 20 at a minimum.

Abstract: 1,178,697. Hydrazonium compounds; isocyanates. ASHLAND OIL & REFINING CO. 26 Aug., 1966 [7 .Sept., 1965], No. 38455/66. Heading C.2C. :[Also in Division C3] 11 The invention comprises compounds of formula where R is a divalent hydrocarbon radical or a radical of formula -R<SP>1</SP>-O-R<SP>1</SP>-, -R<SP>1</SP>-SR<SP>1</SP>-, or -R<SP>1</SP>-SO 2 -R<SP>1</SP>- (where R<SP>1</SP> is a divalent hydrocarbon radical), R 1 , R 2  and R 3  are aliphatic, aralkyl or aryl radicals (aryl being an aromatic radical in which the unsatisfied valence is at a carbon atom of the aromatic nucleus), and R 1  and R 2  may, together with the N atom, form a heterocyclic ring. They are made by quaternizing a compound of formula with a compound R 3 X where X is a radical capable of forming a quaternizing anion and subsequently eliminating HX from the quaternary compounds by treatment with a base or by treating the above acid hydrazide with a compound R 3 X in the presence of an alkali metal alkoxide. The acid hydrazides are made from the appropriate di-acid di-chlorides and unsym. hydrazines preferably by reaction below 15‹ C. in the presence of a solvent. When R 3  is benzylic or allylic the R group in the diacid dichloride should, to prevent the formation of other than the desired products, have a greater migratory aptitude than R 3 . R is preferably a divalent hydrocarbon radical. Preferably R 1  and R 2  are alkyl groups of 1 to 6 C atoms, phenyl and substituted phenyl groups and radicals of such heterocyclic ring compounds as pyrrolidine, pyrrole, pyrroline and piperidine. X is preferably Cl, Br or I. R 3  is preferably an alkyl radical of 1 to 6 C atoms or a phenyl alkyl radical. Preferred diaminimides have the formula where n is 1 to 12, R 1  to R 3  are alkyl groups of 1 to 6 C atoms and Y is H or an alkyl group of 1 to 6 C atoms. The diaminimides may be pyrolysed at above 150‹ C. to form the corresponding diisocyanate and tert. amine. Examples illustrate the preparation of the following products: bis - trimethylamine - (1) - sebacimide, (2) and (3) - azelaimide, (4) - adipimide, (5)- maleimide, (6) - cyclobutane - 1,2 - dicarboximide and (7)-isophthalimide. On pyrolysis the diaminimides yield diisocyanates and tertiary amines and in combination with polyhydroxy compounds provide a stable one-package polyurethane system from which the polyurethane is formed on heating.

Abstract: 1,244,830. Automatic milking barn. A. J. FLOCCHINI. 12 Aug., 1970, No. 38899/70. Heading AIM. In an automatic milking barn apparatus consisting of a number of milking stalls 14-20 and an equal number of holding stalls 24-30 each aligned with a milking stall, cows are fed and prepared for milking in the holding stalls and are automatically forced backwards by push gates 74-80 into the corresponding milking stall when it is vacated. Entrance gate 12, exit gate 52, and stall gates 34-40 and 44-50 are operated automatically in a sequence that enables the cows to move as follows: A cow enters the first holding stall 24 via passage 122 and as it approaches the feed receptacle 72 it operates the feeler switch 62 which starts sprays 64 to wash down the cows rear and closes the stall gate 44. The other holding stalls 26-30 are filled similarly in turn and when the cows have been prepared for milking the first cow is pushed backwards into the milking stall 14 by the push gate 74 which carries feed receptacle 72. This gate stops short and the cow is pushed completely into the stall by the stall gate 34 which carries another feed receptacle 116. When the cow's rump activates the feeler switch 102 the stall gate stops closing and thus different sized cows can be accommodated. The other milking stalls 16-20 are similarly filled in turn and when the holding stalls have been emptied more cows are directed into them. When a cow has been milked it is released along passage 122 and exits through gate 52. The cow from the corresponding holding stall is then pushed into the vacated milking stall.

Abstract: 1,025,235. Hydraulic couplings. SCHWITZER CORPORATION. Oct. 19, 1962 [Jan. 11, 1962], No. 39630/62. Heading F2C. In a viscous fluid coupling, for driving a vehicle radiator cooling fan, substantially as described in Specification 979,629, supply of fluid from a reservoir 23 through a port 35 to a working chamber 24 is controlled by a valve 34 pivoted at 36 to a partition 19 of the driven casing of the coupling, centrifugal action on a mass 38 on the valve 34 urging the latter towards the post 35 against a spring tab 39 so that with increasing output speed the port 35 is progressively closed to reduce the fluid supply to the drive chamber, which, since fluid drains continuously through a port 45 from the drive chamber to the reservoir, causes increasing slip, to limit the fan speed. In Fig. 7 (not shown), an alternative valve 40 pivoted at 42 is urged radially outwardly by centrifugal action against a spring 43, stops 47, 47a limiting the valve movement. The spring 43 may be replaced by a torsion spring wound round the pivot pin 42.

Title: Improvements in and relating to automatic temperature control systems
IPC: G05D23/275
Filed: 1957-12-30
Abstract: 875,077. Automatic temperature-control systems. MACLAREN & CO. Ltd., ROBERT, MACLAREN, I. G., and ADAM, I. R. Dec. 29, 1958 [Dec. 30, 1957], No. 40252/57. Class 38 (4). [Also in Group XXXVII] A thermally sensitive device controlling a main switch in series with an electric heater also controls a switch in a circuit including two auxiliary heaters which modify the effect of the thermally sensitive device when the main switch is open and closed respectively, the main switch opening and closing intermittently to maintain a constant temperature. In an automatic temperature-control system, e.g. for a room or furnace, a rod and tube expansion device 22, Fig. 1, responsive to the temperature, operates a lever 20 so that when the temperature rises to a value determined by the setting of a screw 28 a switch 26 is closed to energize, as shown in Fig. 2, an auxiliary heater 19 causing expansion of a tube 18. The movement of lever 20 and the expansion of tube 18 combine to open a snap-action switch 10 and thus interrupt the supply to the room or furnace heater 10a. The supply to auxiliary heater 19 is also interrupted by the opening of switch 10 so that tube 18 cools and permits switch 10 to re-close. Heater 10a is thus energized intermittently with the ratio of the on to off periods variable to maintain the desired temperature. A high-resistance heater 17 which is energized when switch 10 is open causes expansion of an adjustable tube 14 to assist reclosing of switch 10 thus reducing the temperature differential of switch 10.

[Also in Divisions D1 and F2] In a machine for binding packages P, Fig. 1, the leading end of a binder L is engaged in a clamp 10, which is carried by a driven endless chain C round the package. A knotting unit 9 (see Division D1) then knots the two ends of the binder. The binder is fed from a reel L<SP>1</SP>, round tensioning rollers, and a guiding finger 15 to clamp 10, Fig. 6 (not shown), where it is gripped between a washer (11) and a spring- loaded disc (12). Alternatively the clamp may comprise a rod (44), Fig. 21 (not shown), over which the binder (L<SP>4</SP>) is passed, fixed on a plate (43) mounted on an endless chain (C<SP>1</SP>). A pivotable jaw (45) on the plate (43), spring biased against the rod (44) into gripping position, prevents the binder from slipping off. The clamp is opened by a stationary cam. A block (49) of flexible material, or a spring, fixed on the inner surface of the lever (45) controls the slipping of the binder when released during the knotting operation. After the package has been encircled by the binder, the clamp 10 engages the binder coming directly from the reel, Fig. 4 (not shown), and the knotting unit 9 is advanced transversely above the lengths L, L<SP>2</SP> to knot the ends of the binder together. A bar 37, which clamps the package on to a roller support 5 during binding may also hold in position panels of cardboard or other material fed from magazines B, B<SP>1</SP> which are designed to protect the corners of the package P during binding. Several machines may be coupled together and may be worked alternately.

Title: A method and a device for the continuous refining of molten pig iron
IPC: C21C5/35
Filed: 1965-09-23
Abstract: Pig iron is continuously refined by introducing it as a stream 8 into a refining bath where partial refining has already been effected and remote from where an oxidizing gas is blown in, e.g. through porous refractory elements 13, 24 and <PICT:1114961/C6-C7/1> 26 attached to sealed wind boxes 13a, 24a and 26a in the bottom of the bath tank, so as to cause the metal in the bath to circulate, as shown by arrows 16-20.  The mean carbon content of the bath does not exceed 0.5% to prevent red fume formation and that in contact with the oxidizing gas is 0.2% or less.  As shown, the tank is divided into three compartments 2-4 by two refractory partitions 5 and 6 inter-communicating through openings5a and 6a at the bottom, and the refined metal discharged continuously over pouring tip 9. Lance 14 feeds a slagging agent such as lime suspended in air and lance 15 feeds cooling additives such as lump or pulverulent ore suspended in nitrogen.  Mixing may be assisted by electromagnetic agitation.

Abstract: 1400579 Electro-chemical analysis BAILEY METER CO 1 Sept 1972 [1 Sept 1971] 40592/72 Heading G1N [Also in Division G3] In a solid electrolyte gas concentration cell the reference gas is sealed inside a hollow body formed of solid electrolyte material. The oxygen detector of Fig. 1 includes a zirconium oxide electrolyte tube 16 closed at one end 17 which is provided on its top surface with platinum electrode 22 connected to contact band 24 and on its inner surface with a platinum electrode 30 which extends to the exterior of the tube to connect with band 32, the region of overlap 34 forming the sensing area. A copper-copper oxide reference system 18 fills the tube 16 and is sealed therein by a zirconium cap 12 and high temperature braze alloy 14. Temperature of the cell is measured by a thermocouple formed by platinum electrode 22 and a thick film gold thermoelement 26 at right angles thereto which extends along the top surface to contact band 28. Meter 36 gives the temperature of the cell and meter 38 the difference in gas concentration between the reference and sample. If the operating temperature is kept constant meter 38 gives the partial pressure of the oxygen of the sample directly. This may be achieved Fig. 3 (not shown) (see Division G3) by surrounding the tube 16 at the end 17 with a heating coil the power to which is varied in accordance with variations in the average temperature of the cell as sensed by two thick film thermocouples mounted opposite each other on the inner and outer surfaces of part 17 of tube 16. In an alternative arrangement the cell 10 is insulatingly mounted in a gas sampling chamber with part 17 exposed to the gas being sampled and which flows through the chamber. The temperature signal may be fed through an analogue multiplier into a summing circuit together with the detector cell output to directly compensate for temperature variations.
