Patent GB-710729-A (GB)
Title: Improvements in or relating to high ph aqueous solutions of dihydrostreptomycin sulfate
IPC: C07H15/238
Filed: 1952-01-16
Abstract: A dihydrostreptomycin sulphate product of pH above 6, and preferably of pH 7 to 8, when dissolved in water, is obtained by preparing a mixture of sesqui sulphate (C21H41O12N7)2 3H2SO4 and mono sulphate C21H41O12N7H2 SO4.  An acid salt of streptomycin, which is more soluble in a particular solvent than dihydrostreptomycin sulphate, is reacted in a solvent such as water with a sulphuric acid salt, e.g. ammonium sulphate or an alkyl or alkylol sulphate, which is more soluble than dihydrostreptomycin sulphate in the solvent, so that less sulphate is introduced than is required to convert all the dihydrostreptomycin to (C21H41O12N7)23H2O.  It is preferred to have a sulphate concentration of 1.2 to 1.4 mols. per mol. of dihydrostreptomycin base; the mixtures contain 70-85 per cent of the sesqui sulphate and 15 to 30 per cent of the monosulphate.  Aqueous solutions of 25 to 50 per cent high pH dihydrostreptomycin sulphate have a pH of 7.0-8.0.  Specified salts are the acetate, formate, nitrate, hydrobromide, hydrochloride and tartrate of dihydrostreptomycin; dimethylamine sulphate and triethanolamine sulphate.  Alternatively, the desired amount of sulphate ions may be removed from normal dihydrostreptomycin sulphate, i.e. the sesqui sulphate by anion exchange resins on the hydroxide cycle by passing a solution of dihydrostreptomycin sulphate down a column of the resin. Suitable resins are melamine and phenol formaldehyde resins such as Ionac A-300 (R.T.M.), Amberlite 1R4B (R.T.M.), Dowex 1A and Duolite 3A.  High pH dihydrostreptomycin sulphate is recovered from the solutions obtained by either of the above methods by the addition of a water-miscible solvent such as methanol (preferred), ethanol, isopropanol, ethylene glycol or acetone.

Title: Improvements in or relating to presetting and registering means for liquid measuringand delivery apparatus
IPC: G01F11/00
Filed: 1932-01-21
Abstract: 394,047. Liquid-meters ; valve-actuating mechanism. LIQUID MEASUREMENTS, Ltd. and HAMMOND, F., Victoria Road, North Acton, London. Jan. 21, 1932, No. 1875. [Classes 69 (i) and 135.] In apparatus for delivering measured quantities of liquids of the kind in which a control valve connects a pair of measuring vessels alternately to supply and discharge and a presetting device, automatically zeroized as the quantity is delivered, permits a supply valve to close when it reaches the zero position, the single normally closed supply valve is opened by the presetting device after the completion of the presetting movement. The quantity to be delivered is preset by pushing in a knob 39 on an axially movable shaft 37 to engage clutch parts 41, 43, and zeroize pointers 3 through lever 35 and gear sector 33, and turning the shaft 37 until a pointer 47 indicates the quantity desired on a scale 49. A disc 55 fixed to the shaft 37 is thus turned so that its slot 63 is out of alignment with an arm 65 connected by an arm 73 with the supply valve 75. The knob 39 is then pulled outwards to turn the arm 65 into the position shown, opening the valve 75 and inserting a stop member 69 behind the disc 55 to prevent the knob being pushed inwards. A vertical rod 15 is depressed each time the control valve is operated to empty a measuring vessel, releasing pawls 11, 13 from a ratchet wheel 7 on the shaft 1 of the pointers 3 so that the pointers move through one division. A pawl 79 on the vertical rod 15 also moves a ratchet wheel 61 on the shaft 37 to return the presetting pointer 47 towards zero together with the disc 55, and when the predetermined quantity has been delivered the arm 65 enters the slot 63 in the disc and the supply valve 75 is closed by its spring. A serrated disc 80 on the shaft 37 is acted on by a roller to prevent the presetting pointer 47 being set in a position intermediate the standard volume units.

Title: Improvements in tacheometers
IPC: G01C3/22
Filed: 1924-01-24
Abstract: 210,763. Zeiss, C. [Firm of]. Feh. 2, 1923, [Convention date]. Tacheometers.-For reducing the readings to the horizontal plane in tacheometers in which two images are produced by the inclusion in the optical system of a pair of relatively adjustable half-lenses, at least one of the fittings of the halflenses is caused to abut against a plane surface or to be actuated by gearing so as to be automatically displaced when the elevation of the telescope is varied. The invention is applicable to instruments of the fixed angle type and also to those of the fixed subtense type. Figs. 1 and 2 show the application of the invention to an instrument of the former type, both the halflenses being displaceable. The fitting for each of the half-lenses c<4>, c<5> is provided with two rods c<6>, c', the rods e<7> carrying balls c<8> which are pressed against the plane surfaces of plates d. The plates d are mounted on vertical pivots d<2> on the cradle b<1> which supports the telescope c, the plane of the pivots containing the axis of elevation Y-Y of the telescope. One of the plates d can be clamped by a screw d<1> and the other can be angularly adjusted by a head d<3> which also rotates a gear wheel d<4> meshing with a wheel e to rotate a graduated drum e<1> beneath a fixed pointer b<2>. The head d<3> is turned until the separation of the images is an exact number of graduations of the staff sighted. The plates d cause the separation of the half-lenses to be diminished as the telescope is elevated, the readings being thus reduced to the horizontal. The stadia lines are carried by the plate c<3>. In the modification shown in Fig. 5 the half-lens c<4> is fixed and the rod c<7> of the half-lens c<5> carries a slotted bar c<10> engaged by a pin f<1> on a bevel pinion f which gears with a bevel pinion b<3> carried by the telescope, c so as to be rotated when the telescope is turned in altitude. In a further modification, the telescope carries a pin adapted to traverse a slide when the telescope is turned, and the slide has a wedge-shaped extremity engaging the ball c<8>.

Patent GB-469400-A (GB)
Title: Improvements in the manufacture of abrasive articles
IPC: B24D3/18
Filed: 1936-01-23
Abstract: Porous abrasive articles are made by placing a slip containing abrasive grain, (e.g. fused alumina) ceramic material, granular combustible material, (e.g. coke) and a decomposable gas-evolving substance (e.g. hydrogen peroxide) in a mould so that the gas-evolving substance decomposes therein before the slip sets, drying the resulting article and burning it in a kiln to vitrify the bond and burn out the combustible material.  In this way an article is produced having rotund voids (formed by the gas) interconnected by irregularly shaped voids (caused by burning out the coke &c.)  Sodium pyrophosphate or sodium stannate may be added to the slip to regulate the decomposition of the hydrogen peroxide; these ingredients also tend to separate the coke into individual particles and thus assist the formation of voids of uniform size.  U.S.A. Specifications 1,948,878 and 1,980,954 are referred to.
