Title: Thermoelectric fluid sensor
IPC: G01F23/24
Filed: 1965-07-23
Abstract: 1,120,442. Sensing liquid level, electrically. TRANS-SONICS Inc. July 23, 1965 [July 24, 1964; May 28, 1965], No. 31647/65. Headings G1H and G1N. Liquid level in a tank e.g. engine lubricating oil is sensed by a transducer comprising a thermocouple the hot junction of which is heated by a resistance heating element or by thermo-electric means using the Peltier effect or by-a combination of both. The thermocouple output is dependent only on whether the thermocouple is immersed in the liquid or in air above the liquid, an alarm being operated thereby when the liquid level falls below the transducer level. Resistive heating embodiment. The sensor Fig. 2 & Fig. 1 (not shown) comprises a U-shaped heating filament 28 and a U- shaped wire thermocouple 30 supported by an insulating block 42, the thermocouple having sections 30a, 30b, 30c meeting respectively at a junction 32 which abuts or is welded to the heating filament and at junction 34. Section 30b is of different material from the other sections. Holes 46 in a cylindrical housing 44 admit environmental fluid. To minimize the effect of voltage drop across the junction point 32 on the thermocouple voltage the hot junction 32 may be joined to the heater by a short conductor. Fig. 3 (not shown). When the liquid level is above the sensor it removes heat from the hot junction 32 until the temperature thereof is about the same as that of the liquid. Thus the temperature of the cold and hot junctions are about the same and the thermocouple develops zero voltage. When the liquid level drops below the sensor the cold junction 34 assumes the temperature of environmental air which does not remove heat from the hot junction as rapidly as the liquid so that the temperature of the hot junction increases to a value above that of the cold junction and an output voltage is produced which operates an alarm. Peltier effect heating embodiment Fig. 4 & Fig. 5 (not shown). As shown the sensing thermocouple has a sensing junction 68 and a cold junction 74, the sensing junction being welded to a conductive strand 88 which may also be a resistive heating filament. The material of strands 88, 92, 94 are such that current having a certain polarity, from a source 98, passing through junctions 82, 80 transfers heat from junction 82 to junction 80 according to the Peltier effect. A bridging section 88a of strand 88 conducts heat to sensing junction 68 and when the liquid level drops so that the sensor is exposed to fluid of low thermal conductivity e. g. air, the junction 68 will be at a higher temperature than junction 74 and a voltage is developed at terminals 76, 78. There may be two (or more) sensors Fig. 5 (not shown) to indicate for example maximum and minimum levels in one tank.

Title: Process for the manufacture of pyridyl acetic acid sodium salts and esters therefrom
Filed: 1958-10-03
Abstract: The sodium salt of a 2- or 4- pyridyl acetic acid, which may be alkylated in the nucleus, is prepared by reacting phenyl sodium with 2- or 4-methyl pyridine or an alkyl-substituted derivative thereof and reacting the organo-metallic compound obtained with carbon-dioxide.  The sodium pyridyl acetate so formed may be esterified to a pyridyl acetic acid ester.  Suitably, the methyl pyridine is added dropwise at about room temperature to a suspension of phenyl sodium, obtained from sodium and chlorbenzene in an inert solvent, and the product poured onto a mixture of solid carbon-dioxide and ether.  The resulting pyridyl acetic acid sodium salt may then be reacted with an alcohol, e.g. ethanol, in the presence of a strong mineral acid.  Examples describe the preparation of the sodium salts and ethyl esters of (1) 2-pyridyl acetic acid from 2-methyl pyridine, (2) 4-methyl pyridyl acetic acid from 4-methyl pyridine and (3) 2- (5-ethyl) pyridyl acetic acid from 2-methyl-5-ethyl pyridive and (4) the sodium salts and ethyl esters of 2-(6-methyl) pyridyl acetic acid and pyridyl-2 : 6-diacetic acid from 2 : 6-dimethyl pyridine.

Abstract: 1,256,005. Making pipe fittings; spinning; tube expanding; cutters. M. GRANGER. 24 June, 1969 [25 June, 1968; 13 Aug., 1968; 2 June, 1969], No. 31901/69. Headings B3A, B3C and B3J. Apparatus for flanging around a hole T1, Fig. 2, in a plate or tube T or expanding a tubeend comprises a screw 1 having spinning elements 2 urged outwardly of an end of the screw by a member 3 slidable axially of the screw, and a nut 4 on the screw and engaging the work T so that rotation of the screw rotates the spinning elements 2 and moves them axially relatively to the nut. One, two or more balls 2 are extended through openings in the tubular screw by the end of a plunger 3 slidable in the screw, which may have a left-hand thread. The screw is now rotated, drawing the balls 2 through the hole T1 and forming the flange. If the hole is oval the edge of the flange formed may be in one plane. A washer (7), Fig. 10 (not shown), may be used between the nut and a workpiece (E) if this is flat. If the nut is cut obliquely, oblique flanges may be formed in flat or tubular work, Fig. 11 (not shown). In a modification, Fig. 14, the balls 11 are carried in a separate cage 10 which is rotatable independently of the screw 13, by a drilling machine M. Axial feed is effected by the screw, through a bearing 14 and a flange 10d on the cage 10 which is hollow for reception of the expanding member 12 operated by a pin 12a in a bayonet slot 10a. In another form, Fig. 17, the screw 16 passes through the cage 18 and has a head 16d for expanding and rotating the balls 17. Recesses (not shown) in a part 16c of the screw accommodate the balls when they are contracted in the cage. Cutting.-A milling cutter 21, Fig. 22, may be mounted on the end of the tool which is fixed to a pipe T by a clamp 22. The screw may be rotated by a ratchet -lever, Figs. 18 and 20 (not shown), or the expanding member may be rotated independently by a machine (Fig. 21) or by a ratchet (Fig. 19) for rotating the balls about their centres. In another embodiment, Fig. 24, the end of the screw 45 is formed as hole-cutter 45<SP>4</SP> or is attached to a cutter. The nut 44, formed as clamping jaw, is externally threaded for endwise movement by a nut 40 which is mounted in a bearing 42 on a part of the opposed jaw 39<SP>1</SP>. The jaws are fixed to a bench by a clamp 54. An operating member 47 for extending the balls 48 has a reduced end on which a knob 50 slides between a shoulder 47<SP>3</SP> and a nut 51. For drilling, the screw is turned by a handle 46. With the balls 48 inside the tube T they are expanded by moving the member 47 until the knob 50 engages the end of the screw. The screw is now withdrawn to form the flange, after which the nut 51 is moved within the handle 50 to eject the blank from the drill by means of a projection 47<SP>2</SP> on the member 47. Tube expanding.-In this form, Fig. 23, several tiers of balls 35 are provided of increasing diameter, and/or the operating member 38 may increase in diameter.

Abstract: 1472043 Automatic control of speed UNITED STIRLING (SWEDEN) AB & CO KB 1 Aug 1975 32170/75 Heading G3R [Also in Division H2]  In a generating set, a heat engine 1 driving a generator 2 is operated at varying speeds to allow the speed of the generator to be kept constant as the load varies, and in order to avoid fluctuations in the speed of the generator during periods in which the engine speed is adjusting from one value to another a flywheel and gearing system are used whereby energy is delivered to the generator from the flywheel when the engine speed is increasing, and energy is delivered to the flywheel from the engine when the engine speed is decreasing. The engine is always run at maximum output for each speed, its efficiency then being greatest for each speed. In the arrangement shown, the engine 1 drives the generator 2 via a belt 3 in engagement with a pulley 4 and an axially displaceable roller 5, and the engine 1 drives a flywheel 6 via a belt 7, the roller 5 and a pulley 8. The roller 5 is moved axially to vary the transmission ratios and to vary the energy transmission, as required. Speed responsive devices, e.g. centrifugal governors and servomotors, may be used to monitor the speeds and to shift the roller 5 accordingly.

Abstract: 1521604 Selective signalling INEX Inc 3 Aug 1976 [4 Aug 1975] 32203/76 Heading G4H Apparatus identifies articles from one or more selected ones of a plurality of sources at an identification area spaced from an area at which the articles from all the sources are formed into rows. In glass bottle manufacture, the bottles from a plurality of molds are formed into rows and passed on a belt via a lehr to an identification area. In Fig. 2 (top left), a shift register 36 receives a data pulse each time a row is formed, the speed of the conveyer being detected at 38 to produce a clock pulse train of frequency corresponding to the speed which via an adjustable divider 42 shifts the register 36. An adjustable tap 48 on register 36 in series with an adjustable delay 50 provides a system start pulse when the row of bottles reaches the identification area. In response, a row clock 58 produces a pulse per bottle in the row, stopping under control of a counter 62. Counters 64, 66 are driven in parallel with counter 62 and are reset when counter 64 reaches the number of molds in use. Counter 66 scans (at multiplexer 74) control switches 78 set to indicate molds producing defective bottles, to feed a shift register 76 shifted by the row clock 58. The parallel outputs of shift register 76 actuate respective markers 84 to mark the bottles (for later removal), when enabled by a driver clock 82, a counter 86 counting off the required number of marks per bottle. A unit 60 (between row clock 58 and counters 62, 64, 66) divides by n if only every nth marker is usable (permitting large bottles to be handled) The defective bottles may be removed instead of marked.

Title: Improvements in and relating to diplexing systems
IPC: H01P7/04
Filed: 1962-08-22
Abstract: 1,011,737. Diplex radio signalling. A. ALFORD. Aug. 22, 1962, No. 32259/62. Heading H4L. Relates to a diplexing system in which an aerial is fed through a single feeder from two independent sources operating in frequency bands relatively close to each other, e.g. television sound and vision transmitters. As shown in Fig. 1, the diplexing filter comprises resonators A to E tuned to resonate at or near the sound carrier frequency, and the vision and sound modulated carriers are supplied via lines 1 and 2 respectively. The line 1 is connected direct through the line 3 to the common output line 4 and the line 2 is connected via resonators A, B to the line 4. Sections 8, 9, 10, 12, each of which are equivalent to quarterwave sections at the sound carrier frequency connect the resonators E, D, C, B to the line 3 via coupling loops 13 to 16 and are spaced along the line a quarter wavelength apart. Because of the high impedances appearing at junctions 5, 6, 7, 11 the vision signal is transmitted over the line 3 without excessive reflections and the resonators A, B block the vision signal from the sound signal source feeding line 2. The sound signal is passed with little loss by the resonators A, B to the output coupling line 12. Since the resonator C is resonant at or near the sound carrier frequency a low impedance appears at junction 7, this low impedance appearing as a high impedance at junction 11 and substantially blocking the sound signal from the line 3. Any of the sound signal passing the point 7 is removed by the short circuit at point 6 provided by the resonator D. The coupling requirements for loops 13 to 19 are discussed. In the preferred arrangement resonators C and D are tuned so that one resonates 20 kc/s. above the sound carrier frequency and the other resonates 20 kc/s. below, the resonators A, B being tuned to the sound carrier frequency, so that a wider band of unwanted frequencies is rejected. Resonator E is tuned to or slightly above the sound carrier frequency and is arranged to provide an approximately matched load to vision signals approaching the frequency of the sound carrier. Means for compensating for temperature changes of the resonators A, B &c. as described in Specification 1,011,738 may be included.
