Title: Improvements in or relating to apparatus for selecting samples
IPC: G01N1/04
Filed: 1949-04-06
Abstract: 659,935. Punching-apparatus. UNITED ENGINEERING & FOUNDRY CO. April 6, 1949, No. 9370. Convention date, May 4, 1948. [Class 31 (ii)] [Also in Group XXII] In a machine for punching out samples from a moving strip a selectively-operated punch and a co-operating die are carried in a pair of drums between which the strip passes. The drums 17, 19 are keyed on intergeared shafts 22, 23 in frames 12, 14 on a trolley 11 which is moved along tracks 16 by a hydraulic piston 28 to make cuts over any part of the width of the strip S. An electric motor 27 mounted on the trolley 11 and controlled by a rheostat 27a drives the drums and is coupled to a tachometer generator 34. The punch 21 slides in a radial slot in the drum 19 and is projected beyond the drum face or retracted by solenoids 41, 42 operating through a crank 45, ball-jointed pushrod 49 and toggle links 51, 52 pinned at 54, 58 to the punch and a diametrically opposite abutment on the drum respectively. The co-operating die 71 is slidably mounted in a cylinder 18 containing a resilient ejector 72 and located in a large aperture in the drum 17 by bolts which permit adjustment for registration with the punch 21. The drums 17, 19 have bevelled edges and are enclosed in casings 78, 83 flared in line with the bevels to act as guides for the strip which, after passing between the drums, is subjected to an air blast from a shoot 85 for deflecting the sample upwards, the strip then being deflected downwards over a roller 91 while the sample passes to a collector 86. The solenoids 41, 42 are arranged to operate the punch 21 to take a single sample as required by a system. of electrical relays, the first of which is brought into operation when the voltage of the tachometer generator 34 reaches a predetermined figure, whereupon the solenoid 42 is operated to withdraw the punch 21 within the drum. When a sample is required to be cut a push-button is depressed which brings a further relay into operation which permits a cam-type limit switch 31 on the drum shaft 23 to switch on the solenoid 41 through a further relay, causing the punch 21 to project from the drum and after a cut has been made to switch on the solenoid 42 again so that the punch is withdrawn. The final movement of the switch 31 simultaneously releases the relay closed by the push-button so that the cutting operation is not repeated until required.

Title: Monitoring and controlling the halogen content of a liquid
IPC: G01N27/06
Filed: 1973-02-26
Abstract: 1423314 Electro-chemical analysis HALOGEN CONTROLS Inc 26 Feb 1973 9457/73 Heading G1N [Also in Division G3R] The halogen content of a liquid is monitored by pulsing a parallel combination of a capacitor and a pair of electrodes which are disposed in the liquid and monitoring the decay of the stored charge in the capacitor through the liquid between the charging pulses. The invention is based on the fact that at low voltages e.g. 0.6v across the electrodes the conductivity of the liquid is due only to the halogen content. Fig. 2 shows the invention as applied to a water treatment system such as in a swimming bath or water supply 11. The water is circulated by pump 12 through a conduit 13 in which are disposed electrodes 17, 18 back to the reservoir 11, the addition of chlorine from chlorine source 15 being controlled by a pump 16 controlled by system 14 to keep the chlorine content constant. Circuit details. A uni-junction transistor oscillator 21, Fig. 3 (not shown) drives a pulser 20 connected across capacitor 19 connected in parallel with the electrodes and between pulses capacitor 19 discharges through the water between the electrodes with a discharge rate determined by the resistance of the water which is dependent on the chlorine content of the water. The voltage across the electrodes is fed via the pulser to a high input impedance operational amplifier 22 in the form of a trigger circuit and then to an integrator 23. In one mode of operation the integrator 23 integrates the pulse waveform of the trigger circuit, which is triggered when the voltage across the capacitor 19 falls to 0.1v, relative to the duration of the oscillator pulse and the integrated signal is fed to a meter 26 to provide a reading of the chlorine content. In the second mode of operation the feedback of the amplifier is adjusted so that its output is the decay waveform of the input (inverted) so that less output from across the probe provides a greater output. After intergration the signal is fed to a detector 24 and control circuit 25 the latter including a relay which is de-energized to cause the pump 16 to be activated when the level of the integrated signal is at a level indicating the addition of chlorine. When the chlorine content increases and is detected by the electrodes 17, 18, the integrated signal results in the relay being energized to de-activate the pump 16.

Title: Improvements relating to the production of sulphonamide compounds
IPC: C07D277/52
Filed: 1940-05-31
Abstract: 542,319. Sulphonamido compounds. LEWENSTEIN, M. J. May 31, 1940, No. 9585. [Class 2 (iii)] Para-substituted benzenesulphonamido derivatives of pyridine, quinoline and thiazole are prepared by reacting an alkali metal derivative of an amino-pyridine, -quinoline or - thiazole, preferably under anhydrous conditions, with a benzenesulphonyl halide substituted in the para-position by halogen or a nitrogen-containing group readily convertible into an amino group. The products may be converted into the para-amino compounds, e.g. by treating the halogen compound with ammonia, by hydrolysing an acylamino group or by reducing a nitro or azo group. Nuclear substituents may be present in the benzene ring or heterocyclic residue, and the alkali metal, derivative may have an alkyl, aryl or aralkyl substituent in the amino group. According to the examples, p-acetylaminobenzenesulphonyl chloride is reacted with the sodium derivatives of 2-aminopyridine, 2-aminoquinoline, 5-aminoquinoline, 8-aminoquinoline, 2-aminothiazole and 6-methoxy-8-aminoquinoline, and the products then hydrolysed. Specifications 512,145, 517,272, 531,167, 531,957, 533,495 and 536,216 are referred to. The Provisional Specification also describes the use of a p-aminobenzenesulphonyl halide and of the sodium compounds of 6-aminoquinoline, 6-aminoquinaldine, 4-aminopyridine and 2- amino-4-methylthiazole. The sodium derivatives used in the examples are obtained by grinding the amino compound with sodamide in benzene and refluxing until all ammonia has been removed, except that in the case of 2-aminothiazole, conversion is effected by treatment with a solution of sodium in liquid ammonia.

Title: Improvements in or relating to shuttleless looms with continuous weft supplies
IPC: D03D47/40
Filed: 1956-03-28
Abstract: 837,271. Shuttleless looms. ETABLISSEMENT MATEX. March 28, 1956 [March 28, 1955], No. 9637/56. Class 142(2) Selvedge mechanism, Fig. 3. Mechanism for interlacing a selvedge thread with the looped ends of the weft picks in a ribbon loom consists of a carriage 15 reciprocated vertically on guide rods 7, 8 and on aligned posts 9-12 having gaps between their ends; a bobbin holder 16, also sliding on the posts 9-12, is loosely embraced by arms 17, 18 of the carriage so that a clearance occurs at d when the carriage is rising and at e when the carriage is descending due to friction between the bobbin holder and the posts 9-12. The weft inserting needle carries one limb' of the weft loop through the gap between the posts 9-12 and through the clearance e (which then registers with the gap) and withdraws it when the clearance d registers with the gap, the weft loop being thereby taken round the selvedge thread and also round a wire 37, Fig. 5, carried by the bobbin holder. In a modification, the carriage 15 is pivoted so as to move in an arcuate path, the rods 7, 8 being omitted and the posts 9-12 being replaced by a single pair of curved posts with a gap between their ends. Bobbin holder, Fig. 5. The bobbin 25 is braked by a spring-loaded blade 28, the thread 23 passing over a roller 34, through an eye 35, and over a pulley 36. Immediately under the eye 35, the thread passes through an eye (not shown) on a spring- loaded rod 53, the tension in the thread keeping the rod retracted; if the thread breaks or runs out, the rod is projected to block the clearance e, Fig. 3, to prevent the weft from passing round the bobbin and round the wire 37. Weft inserter, Fig. 4. The weft inserting needle 14 is carried by a plate 39 pivoted at 52, and oscillated by a pin 41 on an oscillating lever 42 engaging a slot 40; the lever 42 also actuates the reed 47 through a link 45. In the position shown, the part 40<SP>1</SP> of the slot is concentric with the pivot 43 of the lever 42, causing the needle 14 to dwell whilst the reed beats-up the weft. Specification 662,195 is referred to.

[Classes 7 (ii) and 7 (vi)] [Also in Group XXIX]  In aircraft engines having the usual supercharger b a second supercharger m supplying its charge by a long pipe to the carburetter e, which supplies the inlet of the first supercharger b, the air inlets to the two superchargers are controlled by valves h, o the former of which is operated concurrently with the driving-gear of the supercharger m. The pipe j is preferably formed with cooling-fins x and a jacket y to which air is supplied at 11 and discharged at 12. The pumps are driven from the crankshaft through twospeed gears t<SP>1</SP>, t<SP>2</SP>, but the second pump , m may be driven by an exhaust turbine. At low altitudes the inlet valves h, o of both pumps are open, but the pump b only is driven through low gear. At a certain altitude a capsule 37  closes a switch 38 to energize a solenoid 36 and adjust the gears t<SP>1</SP> to high speed through a servomotor 26. At a further altitude stage, another capsule 45 energizes a solenoid 44 through a switch 46, whereupon the valve his closed through a servomotor 15, and hydraulic pressure is also conveyed by a pipe 41 to a piston 50 which operates a clutch w to bring the second pump m into action. A further capsule 60 at a still greater altitude moves the gears t<SP>2</SP> to high speed through a solenoid 57 and a servomotor. The inlet valve o of the pump m is then controlled in accordance with the pressure in the outlet k of the pump, by means of a capsule 54 and servomotor 51.
