Title: Television scanning disc
IPC: H04N3/04
Filed: 1938-03-07
Abstract: 506,691. Television. RADIOAKT.- GES. D. S. LOEWE. March 7, 1938, No. 7085. Convention date, March 8, 1937. [Class 40 (iii)] In scanning discs through which a light beam is passed obliquely in order to avoid keystone distortion, the resultant distortion of a polygonal or circular aperture is overcome by using apertures of shape such that their projections on to a plane perpendicular to the light beam are a regular polygon or circle respectively. The holes 12, Figs. 2a, 2b, are preferably formed in relatively thin material 22 arranged to cover larger holes in the disc 11. In a modification, where the thickness of the material 22 is of the same order of magnitude as the diameter of the hole, this may be punched obliquely so that its walls are parallel to the axis of the light beam.

Title: Improvements in or relating to mosaic screens
IPC: H01J29/43
Filed: 1947-03-14
Abstract: 634,318. Cathode-ray tubes. CASSMAN, H., and SALMON, J. G. March 14, 1947, No. 7085. [Class 39 (i)] In a method of making a mosaic screen, insulating material is introduced into the interstices of a mesh carried by a support, the interstices being more open on the outward face; and subsequently the mesh is dissolved leaving a multiplicity of discrete undercut protuberances upon which conductive material is evaporated so as to leave mutually insulated conductive elements thereon. In one method, a layer of lead glass 2 is applied to a support 1, e.g. the glass window of a television tube, and when cool, a flat metal mesh 3 of triangular section, low shadow ratio and fine pitch is laid upon it. The window is heated so that when the glass is sufficiently molten the mesh sinks in up to the ridge 5. Glass may be added to ensure the mesh being covered. The layer is polished away so as just to expose the ridges of the mesh and the latter is dissolved leaving a multiplicity of undercut discrete elements of glass 6. Metal, e.g. antimony or silver, or a compound of these two metals is evaporated in vacuo on to the exposed surfaces 8 of the elements 6 and on to the areas 9 of the window between the elements, thus forming a conducting signal grid 10, which is insulated from the individual elements 8. The latter may be photo-sensitized or caesiated as required. In a modification, finely-divided glass may be settled on to and into the grid mesh, e.g. by water-settling, and cemented with ethyl silicate solution. Material other than glass, e.g. an enamel, may be used.

Patent GB-697642-A (GB)
Title: Improvements in or relating to circuits embodying cathode-ray tubes
IPC: H01J31/06
Filed: 1949-03-17
Abstract: 697,642. Cathode-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 17, 1949 [March 20, 1948], No. 7319/49. Addition to 684,552, [Group XL(c)]. Class 39(i) [Also in Group XL(c)] The multistable cathode ray circuit arrangement claimed in the parent Specification is modified. by moving the beam from one stable position to another by an impulsive change in the strength of the beam current in response to means independent of the tube, the change being such that while it persists not more than two stable positions remain available and when it ceases the beam assumes the desired stable position. As shown, the beam is moved from one stable position to another by applying a positive voltage pulse 16, Fig. 1, to control electrode 15. It is explained that the effect of the pulse is to increase the beam current and consequently the feedback current ia to a position on the dotted line curve 17, Fig. 2, so that the stable points 11, 12, 13, 14, disappear and there are at most only two stable points at the extremities of deflection. When the beam has been deflected to a position corresponding to a new stable point on the original ia-v characteristic 8 the pulse ceases and the original characteristic 8 now obtains so that the beam is held stable at the new position. The electrode 3 is an apertured plate and the electrode 4 connected by feedback path 7 to one deflecting plate 2 is arranged behind it; the apertures in electrode 3 are so designed as to produce a series of maxima and minima on the curve 8 whose values decrease with increasing values of v, as shown in Fig. 2. The electrode 4 is connected to the positive voltage source via conductor 7 and resistance 6, and one end of resistance 6 is connected to a deflecting plate 2; electrode 3 is connected directly to the voltage source by conductor 5. The pulse duration is not critical since if the pulse ceases when the beam is slightly displaced from a stable position, there will be a tendency for the beam to move to the stable position. If it is desired to move the beam in the opposite direction, a negative pulse is applied to electrode 15.
Patent GB-712514-A (GB)
Title: Process for the preparation of tuberculin
IPC: A61K39/04
Filed: 1952-03-21
Abstract: Tuberculin is prepared by a process characterized by entraining tuberculinic substances from filtered cultures of the bacilli by a precipitate of an acid in the nascent state, formed at pH 2.3-3.5. Thus, sodium salicylate, sodium para-aminosalicylate, sodium para-aminobenzoate or sodium borate may be dissolved in the culture medium, and the corresponding acid precipitated by the addition of hydrochloric acid.  The precipitate is dissolved in an organic solvent, e.g. acetone, which precipitates the tuberculinic substances.  The latter are dissolved in water, the pH is brought to 6.5-8 by sodium bicarbonate, and tuberculin is then precipitated by another organic solvent, e.g. alcohol.  It is washed with alcohol, then with acetone, and dried under vacuum.

[Class 100 (iv)] A hood or top plate for covering the ribbonspools and the internal mechanism of a portable or other typewriter is detachably secured to the framework by means of spring clips and a positive latch, the arrangement enabling the hood to be removed without the aid of tools. The hood may have hinge-pins detachably engaging the spring clips. The hood 6 shown in the Figure is provided with hingepins 11 engaging spring-clips 8 on the framework 1, and is secured by a spring-urged latch 14 which is pivoted on the framework and has a lug 17 engaging a hook 29 on the hood. The latch is released by pressing a button 16, and the hood can then be swung backwards, or removed bodily. To prevent release of the hood when it is obstructed by the line-spacing lever or other member on the carriage 4, the carriage-rail 28 co-operates with a lever 21 in connection with a rock-shaft 25 having a finger 26 co-operating with a member 19 depending from the latch. Until the line-spacing lever has moved to one side of the hood, the lever 21 is held in displaced position, the finger 26 obstructs the member 19, and the latch cannot be released.

Title: Improvements relating to flooring and walls
IPC: B61D17/10
Filed: 1931-03-10
Abstract: 370,604. Vehicle and other walls and floors; compound sheet materials. ROBERTS, Ltd., J. W. and ROBERTS, W. N., Armley, Leeds. March 10, 1931, No. 7415. [Classes 103 (iv) and 108 (i).] A floor, wall or wall covering, particularly for a vehicle, is built up from a metal sheet 2 formed with a number of parallel channels of dovetail or other key section and one or more sheets of a non-metallic resilient and deformable material, such as compressed granulated cork, having ribs that are forced into and engage with the undercut metal channels. In the construction shown in Fig. 1, the deformable sheets 1, which are initially provided with a series of parallel rectangular ribs 3, Fig. 3, of a width slightly greater than that of the channel mouths, are applied to both sides of the metal layer, the ribs being initially compressed in forcing them into the channels and then being allowed to expand. If the cork layer is disposed on one side only of the metal sheet it may serve, when secured on the upper side, as a tread surface or, when secured to the under side, as an insulator for sound and vibrations, e.g. in a railway vehicle. A suitable binding- agent may be incorporated with the cork granules, or rubber sheets may be substituted for the cork, while the layers may be cemented together by the use of a bituminous or oxychloride cement or rubber solution. For railway vehicles the metal sheet may conveniently be made of steel, while for motor vehicles aluminium may be employed.

Abstract: 695,321. Automatic temperature control systems. BROWN, W. J. April 4, 1951 [April 7, 1950], No. 7763/51. Drawings to Specification. Class 38 (iv). [Also in Group XXXVI] The detector of a temperature control system consists of one or more condensers having a temperature sensitive dielectric (Rochelle salt, or barium or strontium titanate) connected in series with an inductance forming part of a phase-shifting network controlling the firing point of one or a pair of thyratrons. The network is of the kind disclosed in Specification 656,816. The thyratron controls the temperature corrector which is diagrammatically shown as being: (1) a variable speed electric blower passing air over heater or refrigerator coils for space heating or cooling; (2) an electromagnetic valve by-passing the flow from a boiler to a radiator; (3) a variable speed stoker motor for a boiler; (4) a resistance heater element immersed in a liquid; (4) the supply of electric current to electrodes immersed in a liquid; (6) the supply of high-frequency energy to an ultrasonic transducer heating a liquid; (7) the excitation of an alternator, the temperature of whose armature windings is to be limited. The operating temperature is predetermined mainly by the nature of the dielectric, but may be adjusted by either: ordinary condensers in parallel with the sensitive condenser; varying the inductance in series with the condenser; locally heating the condenser; applying a D.C. bias across the condenser; or adjusting the phase of the voltage applied by the network to the thyratron by a further network.
Patent GB-939987-A (GB)
Title: Gear testing machine
IPC: G01B5/20
Filed: 1962-02-28
Abstract: 939,987. Gear-testing apparatus. FELLOWS GEAR SHAPER CO. Feb. 28, 1962 [April 14, 1961], No. 7774/62. Class 106 (2). In a gear-testing machine in which a retractable feeler 136 is intermittently inserted between successive pairs of teeth of an intermittently rotated gear wheel W and a recording pen 182 makes a record on a moving chart of the feeler movement (via a transducer), the work spindle 69 carrying the gear-wheel is driven intermittently (always in the same sense) by means of a spider 100 to which it is periodically clamped (in a manner to be described below) and which is connected at 40 to a crank-shaft 26 the throw of which, and hence the amount of rotation of spindle 69, is accurately (and adjustably) limited to correspond to the pitch of the gear-wheel being inspected by means of adjustable anvils 45, 46 against which the spherical end 42 of the crank-shaft strikes to limit the throw. The crank-shaft has a telescopic portion 34 to allow this. Mounted on the spindle 69 is an upper spider 101 carrying three pneumatic pressure pads 107a, 107b and 107c (see Fig. 11), which act on the upper surface of a resilient index disc 70 fast with spindle 69 to press the disc rim against a fixed part of the machine and thus arrest the spindle 69 while the spring- loaded feeler 136 enters between the gear teeth. The air-line 163 for supplying pressure to retract the feeler is at this time in exhaust while air-line 159 supplies pressure to move the piston 147a to the left and, via the pawl 161 and ratchet 162, advance the charting paper. As the driving shaft 5 for the crank mechanism rotates, actuating portions 19 and 20 carries by it alternately depress pairs of the four pressure limit-switches 148-151 to so condition the two four-way valves 145, 146 alternately to carry out the pressurizing operations just described and then to reverse them. Pressure pads 113a, 113b and 113c carried by the lower spider 100 now clamp the disc 70 from below against the upper spider 101 and the spindle 69 will now rotate with the throw of the crank-shaft. (The rotation is always in the same sense because during the opposite throw the disc 70 is unclamped from the driving spider 100.) The Specification gives details of an electric circuit for stopping the driving motor when a complete revolution of the gear-wheel has been made. Provision is made for varying the motor speed.
