Title: Improvements in or relating to mechanical drawing
IPC: B43L13/14
Filed: 1953-11-13
Abstract: 763,075. Projection drawing apparatus. HOLMDAHL, R. Nov. 13, 1953 [Nov. 13, 1952], No. 31523/53. Class 97(3) A central projection of an object is drawn mechanically by drawing rod 33 as the end of bar 31 moves from point to point on the surface of an object on table 11. All angular movements of bar 31 are transmitted to rod 33 through shaft 21 and rods 46, 54 which slide in bearings 56 and 47 and are connected to one another by slidable rotatable sleeve 41. The two halves 42, 43 of the sleeve 41 are angularly adjustable relative to one another so that the rods 46, 54 can be arranged other than collinearly. The radial movements of bar 31 are not transmitted to rod 33 and the radial position of rod 33 is continuously determined by the contact of its drawing point 36 with the surface of table 37. The movement transmitting linkage between bar 31 and rod 33 is carried in frame 14 which can be slid up and down on guide 12, 13 on turning threaded bar 65 by means of handle 71. Horizontal sections of an object may be used instead of the object itself and instead of arranging the sections at their correct respective heights above the table 11, the table 37 may be arranged to move with the frame 14 and at a fixed distance determined by the rod 39 from it, and the frame 14 may be moved down towards the table 11 as successively higher sections are placed on it. An elevation of the object may be provided on board 125 attached to frame 14, and thread 129 is then adjusted to the level which corresponds to the section on table 11, by turning handle 71. Many applications are described. When the rod 31 is used, as shown, in a nearly horizontal position, a vertical pilot pin 98 may be provided and is carried on a stand 101. A device operated by thread 105 and pedal 118 may be used to remove the drawing point from contact with the surface of table 37. Since the bar 31 merely gives the direction of various points on the object and not their distance from its centre of angular movement, for very large objects the bar can be replaced by a sighting telescope mounted in sleeve 30 and attached to rod 46. The bearings and other functionally important parts of the apparatus are described in detail.

Title: Improvements in and relating to the treatment of phosphate rock
IPC: C05B11/06
Filed: 1930-10-21
Abstract: Phosphoric acid; ammonium phosphate; calcium and potassium nitrates.--In treating phosphate rock with nitric acid and separating calcium nitrate by crystallization from the resulting solution as described in Specification 339,340, [Class 1 (ii), Inorganic compounds, other than &c.], the crystallization is carried out without the previous removal of insoluble impurities, the calcium nitrate being separated from the mother liquor by centrifuging settling or filtration in such a way that a considerable part of the insoluble impurities remain with the mother liquor on separation of the latter from the coarse nitrate crystals.  The calcium nitrate crystals may be centrifuged or filtered from the mother liquor on a wide-meshed filter cloth or wire netting and are subjected to continuous washing with stirring and decantation with separately applied cold mother liquor from prior operations.  The insoluble impurities may be subsequently removed from the mother liquor either before or after the neutralization of its free acidity, for example with ammonia. The calcium nitrate may be freed from its insoluble impurities by melting it in its water of crystallization and filtering at 75 DEG  C., any free acidity in the crystals being neutralized previously if desired.  If the mother liquor is treated with ammonium sulphate to precipitate the remainder of the calcium from the solution or if the calcium nitrate is reacted with potassium sulphate to form potassium nitrate, the insoluble impurities may be removed together with the calcium sulphate precipitate formed in these reactions.

Title: Resusitator
IPC: A61M16/00
Filed: 1958-10-06
Abstract: 832,474. Respiratory appliances. STANTON, P. L. Oct. 6, 1958 [July 14, 1958], No. 31854/58. Class 81(2). Forced respiration apparatus in which the change-over from inhalation to exhalation is effected by means responsive to the pressure in the lungs, has an auxiliary chamber connected to the patient's supply line to delay the changeover, so as to compensate for the flow resistance of the trachea in children or other small patients. In the control mechanism described, air enters from a tube 7, Fig. 1 (not shown), and passes through an adjustable needle control valve 28 to a chamber 31. From this point its passage is controlled by a doubleheaded valve 32, 33, actuated through a toggle linkage 35 by a piston 36. With the mechanism set as shown in Fig. 3, the gas passes through a conduit 38 to a chamber 39 and thence through a duct 42 to the face mask, until the pressure is sufficient to lift the piston 36. When this occurs, the toggle mechanism changes over and the valve head 32 closes duct 38, while an upper duct 38<SP>1</SP> is opened. This directs the gas to a nozzle 47 and Venturi tube 40<SP>1</SP>, which draws air out of the chamber 39 and face mask, through an orifice 48, and passes it to atmosphere through an outlet 41, until the pressure in chamber 39 has fallen sufficiently for the piston 36 to be drawn back to its lower position. A slight leak always occurs from chamber 39 through the orifice 48 and, in order to reduce this to such a point that the pressure in chamber 39 can build up sufficiently to operate the plunger 36, the orifice is partially closed by a pivoted plate 50 to limit its effective area to a point at which, dependent on the minimum rate of flow through the needle valve 28, the apparatus will still function satisfactorily. According to the invention an expansible container is connected to a further outlet 45 and, serving as a reservoir in parallel with the lungs, slows down the operation of the mechanism and thereby assists complete filling and emptying of the lungs, when the patient has a small or restricted trachea. The control casing carries safety release valves which limit the maximum and minimum pressures in the space 39.

The clamping is affected by a clamping circuits T 5 , T 6 , T 7  fed from an amplifier T 4  whose contrast determining gain is set by the contrast potentiometer K such that varying the gain varies the video signal and the added pulse wi whereby the distance of the maximum C.R.T. white signal level d, Fig. 3, from the pulse wi remains unchanged and only the black level pedestal is displaced. Variation of the brilliance control H also varies the gain of the amplifier but also simultaneously adjusts the clamping level, whereby said distance changes and said black level pedestal is displaced so that the contrast remains substantially constant (Fig. 4).
