Title: Improvements in pirn or tube winding machines
IPC: B65H54/14
Filed: 1919-12-17
Abstract: 162,023. Boyd, T. A., Boyd, H. A., and Boyd, Ltd., J. & T. Dec. 17, 1919. Winding-machines.-In pirn and tube winding machines a revolving shaft serving two or more spindles is provided with a rack pinion for each spindle which meshes with a screwed spindle or rack so as to regulate the position of the spindle relative to its yarn guide, and the pinion and rack may be disconnected so that each spindle may be adjusted by hand. A pinion 20, Fig. 1, loosely mounted between a fixed collar and a spring-pressed friction ring on a shaft 19 driven through reducing-gear from the shaft of the roller 7 that drives the spindles, engages a screwed spindle or rack 14 upon which is mounted a bracket 16 carrying a step spindle 17 which supports and presses the outer end of the tube holder. In this arrangement a cup 10 is used to effect the movement of the spindle after the cop-bottom has been wound, and the shaft 19 is driven at such a speed that the tube is pressed back by the pinion 20 at a less speed than it is by the pressure of the yarn in the cup. The yarn is traversed by a reciprocating guide 13. In arrangements wherein the cup is dispensed with, the tube spindle is carried in a bearing mounted between collars on the rack, or, as shown in Fig. 4, in a U-shaped bracket 78, the front end of which is hinged, mounted on the rack. In this arrangement, the tube spindle is supported laterally at its inner end by the spindle when running, and in a hole in the U-bracket when at rest. The rack may be provided with a thumb collar so that it may be rotated by hand to restore the tube to its correct position relative to the guide, in the event of such adjustment being disturbed, a pointer being provided on the front rail 68, Fig. 4, to facilitate the adjustment. For large adjustments the rack may be disconnected from its pinion and moved longitudinally.

Title: Improvements in or relating to Recording Apparatus.
IPC: H04N5/84
Filed: 1968-07-03
Abstract: 1,196,854. Television. HONEYWELL Inc. 3 July, 1968 [3 July, 1967], No. 31742/68. Heading H4F. Apparatus for recording an image on a recording medium comprises a cathode ray tube adjacent to the face of which is supported the recording medium, horizontal and vertical sweep generators synchronized by separate pulse inputs, and means for blanking the video signal during the horizontal and vertical flyback periods. As shown, television pictures are recorded on a UV sensitive recording medium moved across the fibre optic face plate 28 of a CRT 24 (the recording medium is illustrated in a disengaged position). The pictures originate from a camera 82 which views the scene 86 via a mirror 88 to laterally invert the image and produces a video output at terminal 96 and horizontal and vertical synchronizing pulses at terminals 92 and 94 respectively. The sync. pulses are applied to monostable multivibrators 98 and 112 the outputs of which are connected to integrators to produce the horizontal and vertical scanning signals for the CRT 24. The outputs of the monostable multivibrators 98, 112 are also connected to further monstable multivibrators 108, 122 which gate the video signal to provide blanking during flyback. The recording medium moves continuously in the opposite direction to the vertical scan and at the same speed. The height of the raster displayed is reduced to half its normal value to compensate for the movement of the recording medium. In a first mode of operation a bi-stable multivibrator 124 is triggered by the vertical sync. pulses and is utilized to blank the video during alternate fields so the recorded pictures do not overlap one another. In a second mode of operation a single vertical scan is produced for alternate vertical sync. pulses so that the display comprises two fields arranged one above the other, and due to the movement of the recording medium it can be arranged so that the two fields are recorded in an interlaced manner. A system for recording oscilloscope-type traces is also described in which the input signals are applied to the vertical deflection plates of the CRT. Since the recording medium is moved vertically across the screen during the horizontal sweep the recorded trace would be skewed and to counteract this effect signals derived from the horizontal sweep generator 46 and the recording medium drive system 58 are applied to a skew correction circuit 60 which adds a sawtooth voltage to the vertical deflection signal.

In Fig. 2, input element 26 is a spring loaded plunger which engages a lever 28 engaging a second lever 30 via crossed rollers 34, 36, Fig. 4. Lever 30 is secured to the same pivot 32 as that to which feeler 38 is adjustably clamped. Movement of lever 30 and hence feeler 38 may be prevented by spring-loaded pin 50 engageable with bore 58 in lever 30, the bore being counterbored to allow movement of the feeler only within the scale limits of the indicator when the pin 50 is retracted. The spring bias on the feeler may be reversed by stronger spring 46 acting on lever 30, the spring being disengageable from the lever by rotating pin 50 which has a lug 54. The indicator is mounted in bearing 20 so that as the body rotates the indicator dial may be stopped by magnets 24.

Title: Improvements in thermionic vacuum tubes
IPC: H01J43/06
Filed: 1949-12-19
Abstract: 673,024. Electron multipliers. RADIO CORPORATION OF AMERICA. Dec. 19, 1949 [Dec. 18, 1948], No. 32544/49. Drawings to Specification. Class 39 (i). In an electron discharge tube in which a dynode is exposed directly to an oxide-coated cathode, the tube life is increased by controlling the rate of deposition of cathode material on to the dynode at an optimum value. It is stated that this optimum rate does not only not contaminate the dynode, but may actually improve its secondary emission, and a conjectural explanation is advanced. Several methods of control are described: (1) since the deposition say f(T), will be dependent on the cathode temperature, this may be held to a suitable value ; (2) the cathode coating and base may be chosen to yield a suitable value of f(T) for a desired cathode temperature. An example is given of a cathode base consisting of 99.8 per cent Ni and Co, the remainder of materials capable of reducing the oxides of the coating, and coated with a BaCO 3  and SrCO 3  spray; (3) the fractional ratio a of evaporated material intercepted by obstructions, e.g. other electrodes, may be chosen to provide a suitable reduction in the evaporation rate ; (4) if Ac is the active cathode area, and Ad the active dynode area, the geometrical configuration of the tube is designed so as to give a suitably large value of the ratio Ad/Ac. This is exemplified as about 200, and alternatively defined in terms of a solid angle. An embodiment is described in which a cylindrical cathode is surrounded by a cylindrical dynode. The final collecting anode may be mesh-like and inside the dynode, or it may be outside, the dynode being broken up into a turbine-like configuration. The tubes may have control, screen, and suppressor grids; (5) these methods may be used in any combination. The dynodes may be made of a silvermagnesium alloy containing about 1.7 per cent magnesium. This is heated in an oxidizing atmosphere so that the magnesium diffuses to the surface and forms a thin surface layer consisting principally of MgO, which may also contain some free silver, magnesium, or oxygen. Alternative materials for the dynode surface are BeO, BaO, and Al 2 O 3 . Practical manufacturing details are given, such as dimensions, operating voltages, activating schedules, &c. Comparative curves are given plotting dynode voltage against secondary emission ratios for different dynodes and cathodes, and showing variation of secondary emission and transconductance with elapsed operating life. It is stated that a satisfactory life of at least 200 hours, and possibly much more, is obtained. The tubes may have more than one stage.
