Title: Improvements in or relating to the examination of transparent solid materials
IPC: G01N21/88
Filed: 1938-01-24
Abstract: 509,851. Examining transparent sheets. TRIPLEX SAFETY GLASS CO., Ltd., WAINE, A. C., and DIN, F. Jan. 24, 1938, No. 2308. [Class 97 (i)] Transparent sheet material is examined for homogeneity throughout its thickness by directing a beam of light obliquely into the material and viewing the light emerging after reflection within the material. If the sheet is homogeneous, two images are seen, due to reflection at the front and rear surfaces, but if the sheet is laminated, i.e., has an internal layer of material differing from the outer layers, further images are seen by reflection at the internal surfaces. The invention is particularly intended for testing vehicle windscreens to determine whether they are made of laminated glass. As shown, a lamp 12, provided with a slit and lens system to produce a small intense parallel beam, directs light normally on, to the surface 17 of a glass rhomb 15 which is brought into optical contact with the sheet 26 to be examined by means of a film of liquid. The light emerging from the sheet. after reflection is internally reflected within the rhomb and enters a viewing tube 18. The support 13 for the lamp can be adjusted by a screw 14. A film of opaque material may be applied to the rear surface of the sheet to reduce reflection at that-surface. The rhomb 15 prevents refraction at the front surface of the sheet and so increases the angle of incidence at the internal surfaces.

Title: Improvements relating to cathode ray tubes
IPC: H04N3/227
Filed: 1947-01-24
Abstract: 642,719. Cathode-ray tubes. COSSOR, Ltd., A. C., and DUNTHORNE, J. D. Jan. 24, 1947, No. 2310. [Class 39 (i)] A device for centring an electron beam on the fluorescent screen of a cathode-ray tube comprises a cylindrical axially-magnetized magnet surrounding the neck of the tube, an annular polepiece positioned on one end surface of the magnet and two adjusting devices for displacing the pole-piece relatively to the magnet and to the tube independently in two mutually perpendicular directions. The magnet may be either an electrically energized cylindrical coil or a cylindrical permanent magnet. In the construction shown in Figs. 1 and 2 the neck 1 of the cathode-ray tube passes through an aperture 2 in a non-magnetic metal bracket 3 and an annular felt disc 4 closely surrounds the neck 1 and is held in position by an annular disc 5 of a synthetic resin riveted to the bracket 3. Three pillars 8, 9, 10 angularly-spaced by 90 degrees and 135 degrees are fixed around the periphery of an annular polepiece 6 and a cylindrical axially magnetized focusing magnet 14 is kept axially centred by resting on the slightly yielding washers 11, 12, 13 carried by the pillars 8, 9, 10. The magnet 14 is movable along the neck 1 to focus the beam through the slots 27, 28 in the bracket 3 engaging screws 25, 26 in a support. A mild steel polepiece 15 is riveted to a brass plate 16, the periphery of which engages two eccentrically rotatable diecast cams 17 and 18 carried by the pillars 8 and 9 for adjusting the polepiece in two perpendicular directions. The cams 17 and 18 are pressed firmly against the periphery of the brass plate 16 by a spring strip of metal 22, the ends of which rest in grooves 24 in the cams and the middle of which engages a stud 21 on the plate 16 and the cams can be clamped against rotation by lock-nuts 19 and 20. The polepiece 15 can be locked by tightening the nut 31 on the clamping bracket 32 carried by the pillar 10. The cams 17 and 18 may be formed by stamping. The polepiece 15 and the metal plate 16 may be formed in one piece of mild steel. Specification 519,715 is referred to.

Abstract: 507,089. Photo-electric control of printing-machines. SHURLEY, F., and SHURLEY, Q. H. Jan. 24, 1938, No. 2318. Convention date, Feb. 8, 1937. [Class 40 (iii)] [Also in Group XVI] In multi-colour printing on substantially cylindrical articles such as bottles, cans, bulbs, and tumblers, a photo-electric device is provided to determine the position of the article about its axis to ensure correct regis. tration. As shown, the articles 28, Figs. 1 and 2, are carried between chucks 20, 21 on discs 18, 19 on a shaft 12 rotatable on a frame 10 provided with a printer 11. The chucks 20, 21 are rotatable about their axes, and the chuck 21 is also slidable and urged by a coiled spring to grip the article. The shaft 12 is rotated in steps of 90‹ by a Geneva gear 13 driven by a chain 14, Fig. 7, provided with lugs 17 co-operating with a pawl 15. At each operation of the chain, a lug 17 lifts the pawl 15 and turns the gear a quarter turn, whereupon the pawl engages a notch 16 to lock the gear until the next operative step. While the pawl is lifted, a mercury switch 42 linked thereto is closed, and an electromagnet 38, Fig. 2, is energized. This acts on one end of an incomplete circular band 36 connected to brake arms 33 pivoted at 34, so as to apply these brakes to the chucks 20, 21 to hold the articles against rotation about their axes while shaft 12 is making its quarter turn. Each article held in the chucks is brought in turn between a light source or sources 25, Fig. 4, and a photo-electric device 27. In this position, a collar on the chuck 20 is frictionally gripped by a roller 29 driven by a motor 31, and the article is rotated about its axis, which is that of the chucks, until an opaque spot on the article comes in the path of the light beam, whereupon the motor is stopped and a brake applied to the roller 29 ; alternatively, the roller 29 is pulled away from the collar of the chuck. The opaque spot may be a part of a first print on the article.

Title: Improvements in and relating to pneumatically operated timing devices
Inventor: HUGHES WILLIAM
IPC: B22C15/10
Filed: 1950-02-06
Abstract: 677,469. Moulding machines. BRITISH MOULDING MACHINE CO., Ltd. Feb. 6, 1951 [Feb. 6, 1950], No. 3005/50. Class 83 (i). [Also in Group XXIX] A pneumatically-operated timing device, e.g. for controlling the time a mould is jolted, has a valve and a diaphragm arranged so that a steady air pressure can be applied to the valve to keep it shut while a progressively increasing air pressure is applied to the diaphragm and tends to open the valve, the rate of this increase being adjustable to vary the time before the valve is opened. The valve 28 may be held on its seat 30 and in contact with the diaphragm 24 by a spring 26. The steady pressure is applied above the valve 28 via passages 14, 36, 34 and the increasing pressure, via an adjustable needle ball or valve 20, passage 18 and reservoir 12, below the diaphragm. When the pressure supply to 14 is released this releases the pressure on the left side of a valve 48 and the pressure in the reservoir 12 opens the valve 48 and is thus discharged to reset the timer. As applied to a moulding machine J, air to cause jarring is supplied from a main 86 by a valve 64 which is opened by a shuttle 84 moved to the right by air admitted by a hand-operated valve 93 and pipes 95, 92. Air is at the same time supplied by a pipe 100 to the timer T. When the valve 28 opens the air passes, via a pipe 98, to move the shuttle 84 to the left, thus closing the valve 64 and opening a valve 66 to stop the jolting process and exhaust the pipe 100 to reset the timer. This action can be effected before the timer operates, by opening a valve 931.

Title: An improved process for desulphurizing viscose artificial silk
IPC: D01F11/02
Filed: 1935-02-01
Abstract: In a process for desulphurizing viscose artificial silk, the freshly spun artificial filament from an acid spinning bath is washed immediately after its precipitation with diluted, and as far as possible salt-free, sulphuric acid in individual filaments over a filament stretch of <PICT:0432692/IV/1> several metres, then washed preferably with hot water and dried in known manner.  Suitable concentration of sulphuric acid as 80--170 gms., advantageously about 120 gms. per litre.  Any sulphur left in the filament may then be easily removed e.g. by a simple cleansing with soap, such as is frequently involved in the dyeing or preparation of the products.  In a constructional form, the viscose filament 3 issues from nozzle 1 into the spinning bath 2 and is fed by the driven take-off roller 4 to a pair of inclined cylinders 5, 6 along which it moves helically. Dilute sulphuric acid is sprayed at 8 from the supply pipe 9 on to the upper roller 5 in such a limited amount that it spreads over the roller and only runs off into vessel 10 at the lower edge of the cylinder. Preferably hot water is similarly sprayed from the supply pipe 12 through the spray device 13 on to cylinder 6.  The sulphuric acid may be left to allow the removed sulphur to coagulate, filtered, and used again so long as it has not too great a content of salts. Specification 394,216 is referred to.
