Convention date, Sept. 1, 1933. [Class 98 (i)] In a camera in which there is a view finder chamber above the exposure chamber and in which the view finder objective and the main objective are connected to each other for simultaneous focusing adjustment, a fixed system of lenses is associated with the view finder objective. If a reflecting mirror b is employed in the view finder chamber a, a positive lens d is used to reduce the length of the pencil of rays from the objective c to the screen f. If a dihedral mirror or prism is used, a negative lens is mounted behind the view finder objective to lengthen the path of the rays and enable the dihedral mirror or prism to be unmutilated.

Title: Improvements in or relating to the dyeing of fabric
IPC: D06P5/13
Filed: 1928-08-21
Abstract: 305,922. Spectrum Dyes Proprietary, Ltd., (Assignees of Lloyd, G. F.). Feb. 11, 1928, [Convention date]. Bleaching, processes and materials for.-The colours of dyes fabrics are transformed by saturating the fabrics with a first solution obtained by treating sodium bisulphite solution with zinc, adding a second solution obtained from sodium bisulphite, zinc and the liquor resulting from the treatment of crude coal tar naphtha with dilute sulphuric acid, raising the temperature until the pre-selected colour, available within the range of transformation, appears, and finally arresting the transformation and fixing the colour by adding a suitable reagent, such as acetic acid or sodium bisulphate solution. With fabrics formed of cotton, cotton unions (with wool or silk), or silk, dyed with aniline dyes, the first treatment may be carried out by adding a solution of sodium bisulphite to a wooden vat containing a sheet of perforated zinc supporting the fabric. After treatment with the second solution and the addition of acetic acid or sodium bisulphate to arrest the transformation, the fabric, may be removed and washed with a solution of sodium bisulphate to fix the colour. Small quantities of dyestuffs may be added to the mixed solution to produce colours or shades not normally within the range of transformation. In examples, the colour of silk dyed with aniline black is changed to yellow, red or green by adding small quantities of Chlorazol fast yellow, Safranine, T, or Union pure blue BB to the second solution. The Specification as open to inspection under Sect. 91 (3) (a) describes also the transformation of the colours of dyed fabrics by the action of slowly-acting stripping solutions in general, and is not restricted to the use of the particular solutions referred to above. This subject-matter does not appear in the Specification as accepted.

Title: Improved apparatus for producing perfectly potable distilled water
IPC: C02F1/16
Filed: 1921-09-09
Abstract: 189,879. Calafat, J. Sept. 9, 1921. Water, distilling; evaporators and condensers in structural combination; film evaporators. - Water flows from a tank s over the top of a drum d and down the fabric-covered outer surface of a drum e, star-shaped in cross-section, through the interior of which hot gases rise from a burner r. The gases are deflected against the walls of the casing by a baffle i. The water vapours are condensed on the inner surface of a water-jacketed drum d and condensate flows through an outlet q. Unevaporated water passes to an outlet p. The distilled water may be hardened by adding to the water in the tank s, materials which evolve carbon dioxide, for example, sodium bicarbonate and tartaric acid, and passing the distilled water, in which some of the gas becomes dissolved, through a tank t containing marble.

Abstract: 1,011,333. Piles. COMPOSITE PILING and FOUNDATIONS CO., Ltd. June 21, 1963 [June 22, 1962], No. 24137/62. Heading - E1H.  A locking means for the post-tensioning cables or rods of pre-cast concrete piles and pile sections comprises a pair of frusto-conical members 5 and 6, each with a central bore through which a cable or rod 4 may pass, located in a tapered wall recess 1 having a wall of, e.g. plastic in the upper end of a concrete pile or section. The members 5 and 6 are formed as two complimentary parts such that movement of the cable or rod in one direction during tensioning may take place but reverse movement is prevented by the binding action of the frusto-cones. The wall 1 is provided with an extension 2 for locating the end of a tube 3 through which the cable or rod passes. A number of pile sections may be partly posttensioned as they are driven and tensioned to a higher degree when driving of the pile is completed. Specification 1,011,331 is referred to.

Abstract: 1,260,618. Semi-conductor devices. SOC. GENERALE SEMICONDUTTORI S.p.A. SGS. 19 May, 1970 [9 Aug., 1969], No. 24140/70. Heading H1K. A thin layer 11 of weakly conducting material overlying an oxide layer 5 interconnects opposite sides of a planar PN junction 8, 9 which emerges at a surface of a semi-conductor body 4 below the oxide layer 5. The layer 11 provides a distributed electrostatic potential in the surface of the body 4, and improves the breakdown characteristic of the junction 8, 9. The body 4 may be of Si, the junction 8, 9 being formed by oxide-masked diffusion of B from vapour. The thickness of the weakly conducting layer 11 may vary as shown to control its resistance, or the same effect may be obtained by varying its surface configuration along its length. Discrete highly conductive areas (13a-13d), Figs. 4 and 5 (not shown), may be provided above or below the weakly conducting layer to modify the potential distribution induced in the semi-conductor. The invention is applicable to integrated circuits, diodes, transistors and thyristors.

Title: Improvements in or relating to relieving gearing for lathes
IPC: B23Q5/14
Filed: 1920-08-19
Abstract: 171,766. Drummond, A., and Harris, R. Aug. 19, 1920. Backing-off lathes.-In a lathe for relieving cutters having spiral flutes at rightangles to helically-arranged teeth the relieving-cam is driven through differential gearing to which an additional motion is imparted through change gears to adapt the relieving operation to various spiral angles. The lead-screw B is driven through the usual gearing from the spindle A, which, through bevel - gearing, drives a shaft C connected through a differential D and gears h to a shaft H operating the relieving-cam J. By altering the gears h, the same cam-wheel may be employed to relieve any desired number of teeth on the work. Reduction gearing G is driven from the shaft C and is connected through change gears F to the wheel d<1>, the motion of which gives the required compensating movement to the cam-wheel. The Specification describes the method of calculating the ratio of the gears F, which is equal to tan <2># where # is the angle of the thread helix of the work.
