Title: Improvements relating to Pick-Up Tube Arrangements
Inventor: LUBSZYNSKI HANS GERHARD
IPC: H04N5/217
Filed: 1965-03-03
Abstract: 1,152,231. Pick-up tubes; cathode-ray tube circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. 1 June, 1966 [3 March, 1965; 10 March, 1965], Nos. 9001/65 and 10079/65. Headings H4F and H4T. The invention is concerned with pick-up tubes in the particular application of detecting stars in daylight, wherein the video signal due to the star is of the same order of magnitude as variations in the video signal due to variations of the target sensitivity. In the arrangement shown in the Figure accompanying the Provisional Specification 9001/65 the star and sky are focused by lens 1 on to the target of tube 2. The target is scanned with a raster of 200 line scans, but with each line of the target being scanned twice in succession, such that the scanning order is:-line 1, line 1 again, line 2, line 2 again ... line 100, line 100 again. The first time a line on the target containing a star image is scanned, a video signal is produced due to the image of the star and to the variations in the target sensitivity, both parts integrated over a frame period. Before said line is scanned again, it is illuminated by light from a flash tube 12 equal in intensity to the integrated sky light. The resulting video signal from the second scan contains only variations due to the variations in the target sensitivity. Thus by delaying the first video signal by one line period in 7, a subtraction circuit 8 fed with the delayed first video signal and the second video signal, produces a video signal resulting from the star image signal only. A gate 9 prevents the passing of signals due to the subtraction of video signals due to the first scan of the next line, and the second scan of the first line. In the arrangement shown in the Figure accompanying the Provisional Specification 10079/65, image splitter lens arrangement 21 produces two star and sky images on the tube target, displaced in the line scan direction by a predetermined amount. The video output of the tube, which uses a normal raster scan, is passed, via threshold amplifier 26, to the two inputs of an AND gate 28, both directly and via a delay 27 equal to said predetermined displacement. The two video signals corresponding to the two star images are thus brought into time coincidence at the inputs of the AND gate, and an output signal is thus produced. If it is known that the target has two regions of high sensitivity spaced by said predetermined amount in the line scan direction, the position thereof can be stored and inhibit signals fed to delay means 27 when video signals corresponding thereto appear.

April 2, 1930, Nos. 10444/30 and 95/31. [Class 39 (i).] The supply of permanent gas in a discharge tube is maintained by means of a substance which gives off vapour at atmospheric temperature, the vapour when decomposed by the discharge producing the required gas. Naphthalene and camphor may be used for producing hydrogen and oxides of carbon respectively. The replenishing substances are placed in a side tube connected with the lamp and are kept at atmospheric temperature. The Figure shows a tube intended to give a blue light characteristic of the secondary spectrum of hydrogen. A hollow iron cylindrical electrode 2 is situated at each end of the tube and near each end is a side tube 3 containing naphthalene 4. The latter is housed in a tube 5 having in its open end a graphite rod 6 which is coated with sealing wax to prevent the escape of vapour. A saw cut 8 is made in the upper end of the rod through which the vapour can diffuse. After pumping and the passage of heavy discharges the tube is filled with hydrogen at a pressure of 0À5 mm. Camphor may replace the naphthalene in which case no gas is introduced after the pumping.

Title: Improvements in the treatment of wool
IPC: D06M11/57
Filed: 1927-04-23
Abstract: 290,805. Craven, J. A., and Yorkshire Dyeware & Chemical Co., Ltd. April 23, 1927. Fibres, treating; yarns, treating with liquids.- The tendency of wool to shrink when washed with alkaline soap solutions is diminished by treating the wool, either as loose wool, yarns, or fabric, with basic salts of chromium, iron. or aluminium, or with a weak and slightly alkaline solution of formaldehyde. These treatments render the fibres plumper and less susceptible to shrinking, than the known chlorination processes, improve the softness to handling and increase the capability of fixing mordant dyes and the resistance to putrificative agencies. Chrome tanning liquor such as is used by the tanner may be used, the basicity being increased by the addition of sodium carbonate. The treated wool is washed with water, neutralized with a mild alkali such as borax or bicarbonate of soda, washed and dried; or it may be fat-liquored with a soap-oil emulsion or a sulphonated oil. The two-bath chrome-tanring method may also be used, sodium bisulphite being used instead of sodium thiosulphate to reduce the chromic acid. A preliminary treatment of the wool with an alkali such as lime water or a weak solution of sodium sulphide is desirable, followed or not by bating with a natural or artificial bate to remove the outer scales of the wool fibre. Examples are also described of the treatment of flannel with a basic solution of iron ammonium alum and neutralizing with borax, and also with a cold weak alkaline solution of formaldehyde, neutralizing with ammonium sulphate, rinsing with aired water, fat-liquoring with sulphonated castor oil or other suitable oil emulsion. Where chromium basic salt is used, the product may be dyed with Hematine and many other mordant dyes.
