Title: Improvements in or relating to photographic cameras with focusing range finders
IPC: G03B13/20
Filed: 1937-02-25
Abstract: 490,149. Photographic cameras and coupled range finders. BAUSCH & LOMB OPTICAL CO. Feb. 25, 1937, No. 5673. Convention date, Feb. 25, 1936. [Class 98 (i)] The objective of a camera is connected through a cam to a slidable lens of a coupled range-finder, said lens being one of three negative lenses and adapted to cause the images formed by the other two lenses to be brought into coincidence. The range-Under comprises two spaced lenses 10, 13, an eye lens 12, and a laterally adjustable lens 11. A reflector 14, a semi-reflecting element 15 and compensating lens 16 bring the image forming beams into the eye piece. A bracket 25 is secured to the front wall 24 of the camera and carries a dovetail guide 27. In this guide 27 moves a slide 28 supporting the lens 11, the slide also carrying a roller for co-operation with the cam 30 on the focusing objective. A sleeve 37 supporting the eye lens is slidable in another sleeve 38 on the camera, and is retained and actuated by catches and springs respectively. The objective mount (Fig. 5) comprises an outer sleeve 46 secured to the front wall 48 of the camera by a locking ring 49. A flange 50 on the sleeve 46 conformed with a slot 61 through which passes a pin 60 connecting the cam 30 to an intermediate sleeve 56, screwthreaded on the outer sleeve 46. A pin 58 on the sleeve 56 co-operates with a cam slot 59 on the objective carrying sleeve 54, the latter being prevented from rotating on its guide sleeve by a key 541. When the sleeve 56 is rotated the objective moves and the cam 30 is simultaneously rotated. The slot 61 extends for about half the circumference of the flange 50. Interchangeable objectives can be used, each objective carrying its own cam 30 and focusing mechanism as a unit. Specifications 419,502 and 440,353 are referred to.

Title: Improvements in or relating to the Processing of Textile Yarns or Filaments
Inventor: SHAW WALTER
IPC: D06B19/00
Filed: 1966-02-02
Abstract: 1,191,281. Textile-treating apparatus. W. SHAW. 2 May, 1967 [2 Feb., 1966], No. 5701/66. Heading D1L. Textile material is treated by passing it "through a passage formed with undulating walls whilst a gaseous stream is passed through the passage, the path of the material in the gaseous stream being substantially straight between a material inlet and a material exit, and the gaseous stream travelling in the same direction as the material throughout the length of the passage. The apparatus shown (Fig. 1) is for applying a dye to a single thread 10. The thread 10 is drawn from a package (not shown) and passed through a dye bath 12. It then passes over a roller 13 and enters a glass tube 14 having a series of depressions 15 along opposite sides. At both ends the tube is reduced in diameter and near the entering end of the tube there is provided a branch 17 which is connected to a power driven fan fnot shown). Air blown in via branch 17 builds up pressure in the tube so that there is a flow of air outwardly through the entering hole 16 thus preventing globules of dye carried by the thread from entering the tube and evening out the level of dye on the thread. Also the air blown in creates a stream of air through the tube in the same direction as the thread, but turbulence is created by the undulations 15 and the thread is held suspended in the air stream. Heat is applied to the tube e.g. from an infra-red heater 18 under the tub's and a reflector 19 above the tube and thus the thread is subjected to a drying/action as it passes through the tube. On leaving,the tube the thread is collected into a, package 20 in a hot air curing or steam development chamber 21 according to the type of dye used. Two or more sets of such 'apparatus may be arranged in series. In a second embodiment threads from a warp beam are formed into a sheet and passed through a chamber having an undulating bottom and a lid with an undulating under surface. Air can again be blown through the chamber and can be recirculated 'through a return chamber situated beneath the treatment chamber. Steam, preferably superheated may be introduced into the return chamber.

Abstract: 547,922. Loud-speakers ; measuring sound intensity. STANDARD TELEPHONES & CABLES, Ltd. May 2, 1941, No. 5719. Convention date, July 17, 1940. [Classes 13 and 118 (ii)] [Also in Group XXXIX] In a method of absorbing sound waves, e.g. at the back of a loud-speaker diaphragm, or in apparatus for measuring the intensity of sound the sound waves are transformed from their natural velocity to a high-particle velocity and then absorbed. This may be done by a tapered horn having sound absorbing material in its throat portion, or the walls of the horn may be of sound-absorbent material. The portion 34, Fig. 3, of the horn near the diaphragm 30 may be cylindrical for a distance not exceeding a quarter wave length of the lowest frequency to be absorbed, followed by a portion having a taper exceeding the exponential curve, and a third portion having an exponential taper. The horn may vary in cross-section from point to point, Figs. 2, 2A, 2B, or be coiled to reduce its length, or may be divided into a number of tapered portions by axial partitions, Fig. 5 (not shown). For measuring sound intensity, a microphone or Rayleigh disc may be mounted in an outer tube leading into a tapered horn, Fig. 1 (not shown).

Abstract: 703,006. Regulation of pumps. TUHNER TANNING MACHINERY CO., Ltd., and HALL, C. Feb. 4, 1952 [March 13, 1951], No. 6039/51. Class 102 (1). [Also in Groups VIII and XXIX] In a leather working machiue, in which a roller 43 is mounted on swing arms 40 so as to be movable into co-operative relation with a roller 17 and a rotary tool 17, the mechanism effecting the movement of the arms 40 is hydraulically controlled, and comprises piston rods 51 directly articulated to the upper free ends of the arms, and provided with pistons 52 arranged to work within cylinders 55 pivoted to the sides of the machine. The hydraulic mechanism, shown diagrammatically in Fig. 5, comprises motor-driven low pressure-high delivery and high pressure low delivery pumps 83, 84 respectively, which at the appropriate setting of valve 67 by treadle. 76, deliver oil from reservoir R through pipes 92, 65, 63 to the lower end of cylinder 55 thereby causing speedy movement of piston rod 51 and arm 40. Oil in the upper part of the cylinder discharges through valve 99. As the stops 113 are forced back by abutments 112, the increasing oil pressure moves a spring loaded piston 100a in valve 100 so as to cause the low pressure pump 83 to discharge through pipe 107, the full working pressure being built up by pump 84. A manually adjustable relief valve 103 is provided in the high pressure line. On release of the treadle, the oil feed is transferred to pipe 71, and the piston is forced down the cylinder, oil in the lower portion being discharged through pipes 64, 65, 97. Near the completion of the stroke, oil beneath a choke piston 53 escapes through a bleed hole 54 therein, thereby providing a dash pot effect. The pumps and valve 67 &c. feed two cylinders &c. one at each side of the machine.

Abstract: 1,135,031. Shrinkproofing wool. PRECISION PROCESSES (TEXTILES)) Ltd. 10 Feb., 1966 [11 Feb., 1965], No. 6077/65. Heading D1P. Wool and wool-containing materials are rendered shrink resistant by continuously passing them in a continuous form at substantially constant speed through a bath containing an aqueous liquor containing a shrink-resistance imparting oxidising agent for wool, a water soluble salt and a wetting agent e.g. the condensation product of trimethylnonyl phenol with 6 moles of ethylene oxide and continuously withdrawing the treated materials after a predetermined sojourn in the bath liquor, during which sojourn reaction takes place between the oxidising agent and the materials, whilst continuously withdrawing bath liquor at a predetermined rate and continuously introducing fresh aqueous liquor containing the oxidising agent, salt and wetting agent at a rate just sufficient to replace the withdrawn liquor, the concentration of oxidising agent in the fresh liquor just sufficing to replace the amount of oxidising agent consumed in the bath and any residual oxidising agent present in the withdrawn liquor whilst the concentration of wetting agent is substantially the same as that in the withdrawn liquor and the concentration of water-soluble salt in the initial bath is adjusted so as to be substantially equal to the concentration thereof in the fresh aqueous liquor so that the concentration of oxidising agent in the bath rises or falls with passage of the materials until an equilibrium is reached when substantially the desired consumption of oxidising agent takes place whilst the concentration of water-soluble salt therein remains substantially constant. The oxidising agent may be permonosulphuric acid and the water-soluble salt ammonium or potassium sulphate, or the oxidising agent may be sodium or potassium dichloroisocyanurate acidified to pH 2 with hydrochloric or sulphuric acid and the watersoluble salt sodium or potassium chloride or sulphate. If the woollen materials contain oil, an oil may be dispersed in the initial bath liquor in an amount at least sufficient to reduce overall gain of oil by the bath liquor during passage of. the -woollen materials therethrough. The materials may subsequently be treated with a reducing agent, e.g. sodium and potassium sulphites and bisulphites and mixtures thereof.
