Title: Phosphoric acid production
IPC: C01B25/22
Filed: 1967-11-07
Abstract: 1,201,200. Phosphoric acid ; calcium sulphate semi-hydrate. DORR-OLIVER Inc. 7 Nov., 1967 [8 Nov., 1966], No. 50575/67. Heading ClA. Phosphoric acid containing 37 to 45% by weight P 2 O 5  is produced by acidulation of phosphate rock with phosphoric and sulphuric acid using in a first treatment zone 10 (Fig. 2) phosphoric acid containing 37 to 45% P 2 O 5  and insufficient sulphuric acid for stoichiometric reaction with the calcium producing a slurry of calcium sulphate semi-hydrate suspended in phosphoric acid and containing dissolved monocalcium phosphate and then acidulating in a second zone (20) wherein the sulphate ion concentration is in excess of the amount necessary to stoichiometrically react with the availabe calcium and is maintained in the range 3 to 6% by weight to precipitate all the calcium as calcium sulphate semi-hydrate and give the phosphoric acid product. Semi-hydrate is filtered in 30, washed with the initial filtrate from 50, repulped with subsequent filtrate from 50 and recrystallized as gypsum in 40. Phosphate rock may be added at 28, or to the product acid at 62 to reduce the sulphate ion concentration. Evaporative cooling in 16 to which slurry produced in 20 is circulated helps maintain the required temperature in the acidulation zones.

The polymer is preferably formed from 10-30 parts by volume of acrylic or methacrylic acid and 50-90 parts by volume of a C 1-4  alkyl acrylate or methacrylate, per 100 parts by volume of the total monomers. The polymer may also be additionally formed from 5-20 parts by volume of a C 8-18  alkyl acrylate or methacrylate as the same basis. The polymer is preferably initially formed into an article such as a contact lens, which is then dipped into a solution of the imine, and neutralized. It is then capable of absorbing, and gradually releasing medicaments such as pilocarpine hydrochloride.

Title: Rotating-anode x-ray tube
IPC: H01J35/30
Filed: 1973-11-01
Abstract: 1469932 Automatic control of speed NATIONAL RESEARCH DEVELOPMENT CORP 23 Oct 1974 [1 Nov 1973] 50841/73 Heading G3R A rotating anode x-ray tube wherein the x-rays are extracted in a direction nearly parallel to the axis of rotation, comprises an anode in the form of a wheel 2 with a uniformly serrated rim, the electron beam being scanned across the rim. The frequency, phase and waveform relationships are discussed and are such that the spot will appear stationary when viewed in a direction lying in a plane passing through the axis of rotation and making with the axis an angle, e.g. 4 degrees, whose tangent equals the serration depth/the length of scan. The scanning waveform may be triangular for a V-shaped serration, e.g. a 90 degrees V-shape serration in a Cu block, the pitch being twice the radial depth of 1 mm, or a more nearly sinusoidal waveform for a radiused channel section to avoid overheating at the point of scan reversal. Fig. 3 includes sensor 18 monitoring shaft rotation, its output being converted to equivalent scanning frequency for comparison with scanning waveform generator 19 output. A difference signal from comparator 20 corrects either generator frequency or rotary drive speed. A second output from sensor 18 cuts off the h.v. power supply to the gun if the anode speed is seriously reduced. Anode serration position is monitored optically by means incorporated in x-ray camera 22 or mounted at a separate port, an indexing signal to generator 19 controlling phase. The scan width and gun supply are controlled manually.

A displaceable wall member 17 of the magazine is acted on by the cigarettes so that when a pre-determined maximum number of cigarettes is piled up above the shoots 11 a switch 19 is operated, thereby stopping the cigarette making machine. The machine may also be stopped by extreme positions of the feeler 19. Cigarettes are distributed in the magazine by rotary members 33 and further rotary members 29 each of substantially square cross-section and which carry distributing arms 32.
