Title: Apparatus for use in the control of distillation
IPC: G01N25/14
Filed: 1961-07-06
Abstract: 953,906. Determination of the end-points in the distillation of liquids. BRITISH PETROLEUM CO. Ltd., and W. H. TOPHAM. June 14, 1962 [July 6, 1961], No. 24459/61. Heading B1B. [Also in Division Gl] In an apparatus for the determination of the end-point in the distillation of a liquid, the supply of heat to the still is reduced or cut-off electrically by a temperature controller 8 responsive to a signal received from e.g. a thermocouple 7, located in the still bottom or in the heater, when the temperature of the still bottom rises above a preselected temperature. The overhead temperature is detected and recorded electrically and, preferably, the detector 4 is disconnected from the electric recorder 5 by the action of controller 8 so that the recorder 5 registers a peak value of the overhead temperature at the end point of the distillation. Preferably the heater used is an electrical heater. At the start of the determination, switch 11 is closed, and push button 14 is depressed to connect relay 10 with a source of electricity. When relay 10 is energized, it closes contacts 12, thus maintaining the circuit between relay 10 and the source of electricity. The relay also closes contacts 9, thus supplying electric current to heater 6, and opens contacts 13. When the still bottom reaches the preselected temperature, the controller 8 opens switch 11 to disconnect relay 10. Contacts 9 and 12 then spring open, thus switching off heater 6, and contacts 13 close, thus shorting out detector 4.

Abstract: 337,094. Colassi, W. L. Jan. 29, 1930. Magnetic instruments. -The reed of a loudspeaker or other soundreproducing apparatus of the kind which comprises a diaphragm operatively connected with a reed having lateral supporting arms under tension and supporting the reed in a magnetic field is directly mounted by the extremities of its supporting arms 29a in such manner that tension is applied to to the arms during the act of mounting. The arms 29<a>, Fig. 1, may be integral with the armature portion 29 of the reed and disposed and tensioned in the same plane as the armature, and may be arranged in the form of a T, X, or Y with the central portions 32 of the arms apertured or reduced in thickness for lightness. The ends of the arms 29a are clamped by nuts 26 to bolts 21 which are secured at their lower ends to a base 2 of non-magnetic material, the bolts being spaced slightly further apart at their lower ends than the holes in the arms of the reed so that tension is applied to the reed when the securing nuts 26 are tightened. A platform 5, to which a horseshoe magnet 17 with pole pieces 19 and voice coils 22, is clamped is pivotally attached bv trunnions 6 to pillars 3 carried by the base 2. Small springs 8, 9 tend to turn the platform 5 about the pivots 6 in one direction against a much stouter spring 10 on the opposite side of the pivots, a set screw limiting the movement. The platform and magnet are adjusted relatively to the reed by a screwed rod 11 screwed to the platform 5 and passing through a bush or sleeve 13 carried by the base 2. A lock nut 14 is provided for mounting the unit, which is enclosed in a dust-proof cover. In a modified construction of reed, Fig. 17, two reeds 29a similar in construction to the ones described above are superimposed and spaced apart at their outer ends and are placed in further and adjustable tension by drawing them together at the centre.

Title: Process for the production of an improved cellulose
IPC: C08B1/00
Filed: 1927-09-20
Abstract: 288,997. Wolff & Co., and Weingand, R. April 19, 1927, [Convention date]. Preparatory treatment of cellulose.-Cellulose which has been freed from hemicellulose, wholly or in part, by treatment with alkali is treated with a salt solution or an aliphatic alcohol prior to washing with water, whereby the formation of further amounts of hemicellulose is avoided. Suitable salt solutions are solutions of sodium chloride and potassium sulphate. In an example, ordinary cellulose is stirred with soda lye, the bulk of the lye is removed by means of a centrifuge, aspirator, or cell-filter, and the soda cellulose so obtained is treated with sodium chloride solution, either directly or after a further washing with a small amount of alkali lye, and is allowed to stand. Then, after removing the liquid, the cellulose is washed with water until the washings are only feebly alkaline, the residual alkali is removed with hydrochloric acid, and the cellulose is thoroughly washed and dried. The washings may be used again in the process.

A spacer grid for supporting and spacing the fuel rods of a nuclear reactor fuel bundle comprises a peripheral support band, a plurality of divider means forming a plurality of separate fuel rod passages of square cross-section, one for each of the fuel rods, and a plurality of spring assemblies providing a spring member extending diagonally into each fuel rod passage for resiliently restraining lateral movement of the fuel rods, the divider means including protuberances of limited area extending into the fuel rod passages to limit the area of contact between the fuel rods and the divider means, In one embodiment, a first group of spaced divider members 21 formed of sheet metal is rigidly supported between opposite sides 20(1), 20(3) of a peripheral support band 20 and a second group is rigidly supported between opposite sides 20(2), 20(4), the divider members of the two groups intersecting at right angles and being appropriately slotted to interlock at the intersections. In addition, divider wires 2 are arranged in vertically spaced pairs with a first group supported between sides 20(1), 20(3) and a second group between sides 20(2), 20(4). Each of the divider wires 22 is crimped along its length to form a series of S-shaped curves centered along the sides of the fuel rod passages. Supported at each intersection of the divider members 21 is a four-sided spring assembly 23 slotted along each side edge and with each side curved outwardly to form outwardly extending spring members supported between upper and lower end portions.

One of the audio signals is modulated on a subcarrier at 4 before being passed to the audio carrier generator 2. The two video signals from 5 and 6 are passed to a carrier generator 8 by a switching circuit 7 which switches between the outputs of 5 and 6 to pass the output of 5 during alternate line periods and the output of 6 during the intervening line periods. The switching circuit 7 comprises a bi-stable multi-vibrator 12, Fig. 2, operated by the horizontal synchronizing pulses from a synchronizing signal generator 9 via transistors 48, 54. The output of multivibrator 12 alternately switches on and off transistors 24 and 33 so that the signals from 5 and 6 are fed to carrier generator 8 on a linesequential basis. During the vertical blanking period the vertical synchronizing signals from generator 9 are integrated by resistor 58 and capacitor 59. When the integrated signal reaches a predetermined value transistor 69 is cut off and the collector voltage of transistor 69 rises, and triggers a monostable multivibrator 75. The output from the multivibrator 75 is passed to a multivibrator circuit 77 which includes a transistor which is cut off by this output, so cutting off the power supply to bi-stable multivibrator 12 for a predetermined period. The output from monostable multivibrator 75 also cuts off transistor 54 for a longer period, so that the output of the multivibrator 12 is zero during the vertical blanking period, transistor 24 being biased on and transistor 33 off, and all the vertical synchronizing signals from generator 5 are transmitted, so that the first complete line of each field transmitted is derived from generator 6.
