Title: Apparatus for purification by sublimation
Inventor: BALANGE PIERRE HENRI
IPC: B01D3/12
Filed: 1957-12-03
Abstract: An apparatus for purification by sublimation, by heating the substance in a vacuum to a temperature below its boiling point and collecting the sublimed solid, comprises a plate formed from two angularly spaced sectors of a circle secured at their apices to a common support; means for heating the plate; a cooled rotating disc which is disposed in closely spaced relationship, i.e. a few millimetres above the fixed plate and scraping means disposed between the sectors so that the purified condensed material is scraped off the condensing plate or disc and falls between the sectors and can be collected.  The material on the fixed plate can be mixed with inert material for heat conduction and large surface area.  The whole apparatus is enclosed in a vacuum chamber.  Substances can be obtained in a high state of purity by this method and the size of the crystals of the purified products can be regulated by allowing them to grow more or less large in the sublimation chamber.ALSO:Meta-nitro-para-toluidine in a liquid state at a temperature of 15 DEG  C. is introduced at a flow rate of 100 cc. in 4 minutes on to a heated plate maintained at 120-122 DEG  C.  The liquid vaporizes and the vapour condenses directly as a solid on the cooled surface of a superimposed disc maintained at 15 DEG  C. and rotating at 1.4 revolutions per minute.  The plate and disc are enclosed in a casing maintained at low pressure.  The solid obtained by sublimation is in the form of orange yellow crystals (M.P. 115 DEG C.).  It is removed from the disc by means of scrapers and collected. The product is obtained in a high state of purity and may be subjected to diazotization by standard methods without leaving any residue.

Title: Circuit for indicating a delay time of a delayed pulse
IPC: H03K17/28
Filed: 1970-08-05
Abstract: 1325456 Pulse generating circuit IWATSU ELECTRIC CO Ltd 5 Aug 1970 [27 Aug 1969] 37765/70 Heading G1U A circuit is described which produces an output pulse a predetermined time after an input pulse, and which also indicates whether the predetermined time exceeds the time taken by an oscillator to generate a pre-set number of cycles. In a first embodiment, Fig. 1A, an input pulse 1, Fig.1B sets a bi stable gate signal generator 3 ON to produce a high output. This initiates a linear ramp signal 29 within a first delay pulse generator which is compared (also within the first delay pulse generator) with a pre-set reference level 28 supplied by a delay time calibrating signal generator 7 to produce an output pulse 6 when the ramp rises to the level of the reference. The output pulse 6, which thus occurs a pre-set time (determined by the rate of rise of the ramp and the reference signal) after the input pulse 1, is fed back to reset the gate signal generator - which has a duration equal to the pre-set time - and is applied to a signal generator 8 causing it to produce a burst of pulses proportional in number to its duration. These pulses are counted by a selector 9 which if a pre-set count is exceeded, produces an output pulse 11 to turn ON a trigger 12, 13 to produce a resulting delay time indicating first signal 24. The trigger 12, 13 is reset by the leading edge of the signal 25 from the gate signal generator 3 - via a differentiator 21, 18 and rectifier 14 - and if the signal 25 from the gate signal generator 3 is not sufficiently long, as determined by the frequency of the signal generator 8 and the count pre-set into the selector 9, then the trigger 12, 13 remains reset. In a modification Fig.2A (not shown) a second trigger (31, 49) is provided which is arranged to be turned on by the trailing edge of the signal 25 from the gate signal generator 3, if the signal 25 is not sufficiently long to produce an output pulse 11 from the selector 9.

Title: Improvements in or relating to apparatus for use in connection with sound recording upon film
IPC: G11B7/00
Filed: 1930-12-17
Abstract: 369,989. Optical sound - recording apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, and ROUND, H. J., Westfield, Muswell Hill, both in London. Dec. 17, 1930, No. 38085. [Class 40 (ii).] Relates to apparatus for recording sound on a film by the " variable area " method, and consists in providing a device comprising auxiliary mirrors and a ground glass screen for enabling the narrow beam of light used in recording to be accurately adjusted and for allowing the movements of the beam to be observed during the working of the apparatus. The recording beam is concentrated by a cylindrical lens C upon the film F, and between the lens and the film is a member K which carries a mirror M arranged at an angle of 45‹, and which is adapted to slide between two adjustable stops S<1>, S2. When the carrier K is moved by a handle H, against the action of a spring, until it abuts against the stop S<1>, the edge E of the mirror is exactly in line with the edge El of the film, and a line L on the mirror is exactly in front of the position R on the film which is to be the centre line of recording. In this position of the mirror, the recording beam is reflected by the mirror M and by a second mirror M<1> on to a ground glass screen G, which enables it to be properly focused. The image of the line L on the screen serves as an indication for setting the light recording edge, for example by adjusting the oscillograph mirror. When this adjustment has been made, the carrier K is allowed to spring back against the stop S<2>. The mirror M is then in the position shown in Fig. 2, where it remains during recording, so that it reflects a portion only of the vibrating beam on to the screen G. The amplitudes of vibration may thus be seen on the screen, by direct observation or by means of a rotating mirror or the like.
