Title: Improvements in the Optical Systems of Rangefinders and the like Telemetric Instruments.
Inventor: TAYLOR ALFRED
IPC: G01C3/22
Filed: 1917-07-31
Abstract: 128,312. Taylor, A., and Gray, P. W. July 31, 1917. Range-finders ; optical systems.-A pentagonal prism or optical square pivoted about an axis parallel to the planes of its reflecting surfaces and srranged between the object-glass and the eve'- piece of a telescope is used as the measuring device, the angle through which the prism is turned being a measure of the range. Eig. 1 is a plan view of one end of a short-home-base rangefinder. The pivoted prism 6 is arranged to cover half of the eye-piece field-lens 9, and is rotated by means of a cam 15, against which bears a lever 14 connected to the prism; an operating handle and an indicating dial 16 are provided for the cam 15. Light enters the end shown through the objective 5, and is received by the prism 6 ; light from the other end of the instrument after deflection by an optical square is received by the objective 12 and enters the fieldlens 9 directly. A roof-edge prism 11 is placed between the eye-piece components. An instrument of the Mekometer type is shown in Figs. 2, and 6; Fig. 2 is a plan of a left-hand instrument, and Figs. and 6 are plan and sectional elevation respectively of a right-hand instrument. The four-lens eye-piece 17, Fig. 6, receives in one half light from the pivoted prism 19, to which is attached a lever 21 engaging a cam 22 carrying a graduated dial 25 and provided with an operating head 24; the prism 17 is used for viewing with the aid of an interposed objective a mark on a pivoted plate 28 on the other instrument, a direct view of the object, ranged on being obtained through another objective 27 directly in line with the eye-piece 17. The left-hand instrument is also provided with a pivoted pentagonal prism for viewing a mark on the pivoted plate 37 of the other instrument; zero correction is obtained by means of an adjusting screw 34 bearing on a lever 33 attached to the prism. The preferred axis for pivoting the prism is coincident with the intersection of the normals through the centres of the incident and emergent surfaces; this maintains the focal plane constant in position. In certain cases, compensation for movement of the focal plane is obtained by displacement of the objective by a ccnnexion to the prism. The focal plane of the objectives is preferably at or substantially near the emergent surface of the prism. In order to obtain a better illumination at the centre of the field, the prism may be moved slightly back from the focal plane and raised together with the other objective slightly out of line, the consequent deviation being corrected by means such as a tilted parallel plate or an achromatic prism. In instruments other than short home-base, logarithmic scales may be provided for enabling the base used to be varied and the range to be read off immediately, as described in Specification 1589/15, [Class, 92 (ii), Ordnance &c.].

Patent GB-467812-A (GB)
Title: Improvements in or relating to the production of artificial filaments, threads, films and the like
IPC: D01F4/00
Filed: 1935-10-22
Abstract: Artificial filaments, threads, or films are obtained by extruding a solution of casein in aqueous urea solution through an orifice into a diluent or other regenerating medium.  The urea solution has a denaturing effect on the casein dissolved therein. Round, elliptical, solid, or tubular filaments may be obtained. The viscosity and stability of the casein solution may be adjusted by the addition of a small proportion of glyoxal polymer, formaldehyde, benzaldehyde, ethylene oxide, glycide, salicylic acid, gelatin, acetophenone, triacetin, sorbitol, glycerol, glucose, polyglycol, triethanolamine, or thiourea.  These auxiliary substances may also be added to the coagulating bath or a subsequent treatment bath.  The regenerating medium may be water, dilute solutions of sodium or ammonium sulphate or sulphite, zinc chloride, sulphuric acid, acetic acid, or mixtures of these substances.  The mechanical strength of the filaments may be increased by immersing them in solutions of formaldehyde, dichromate, chrome alum, tannic acid, picric acid, potash alum, aluminium chloride or sulphate.  The softness may be enhanced by immersion in solutions of waxes in oils or alcohol.  In an example, sheet gelatine, formaldehyde, salicylic acid and urea are dissolved in water.  The solution is stirred with casein until the latter is dispersed.  The resulting solution is centrifuged, ripened, and then extruded into a solution of ammonium sulphate, zinc chloride, glacial acetic acid, and water.  The filaments obtained are wound on a spool which dips into a solution of glycerol and water, or sorbitol and water.  The wound spool is immersed in a third bath of the same composition as the second. The filaments are then treated with formaldehyde, washed, and p  dried.  They may be treated with a softening solution containing a small proportion of urea, and also with a solution of paraffin wax in olive oil.ALSO:Dispersions of casein in aqueous urea solution are rendered more stable by the addition of a small quantity of glyoxal polymer, formaldehyde, benzaldehyde, ethylene oxide, glycide, salicylic acid, gelatin, acetophenone, triacetin, sorbitol, glycerol, poly-glycols, glucose, triethanolamine, or thiourea. In an example, sheet gelatine, formaldehyde, salicylic acid, and crystalline urea are dissolved in water.  The solution is then mixed with casein which is added slowly with stirring.  The casein disperses rapidly to form a viscous solution which is subsequently extruded to form filaments or films.
