Title: Improvements in and relating to television apparatus
Inventor: TURREL ROBERT AMBROSE
IPC: H04N9/04
Filed: 1963-04-04
Abstract: 1,044,024. Colour-television. RANK-BUSH MURPHY Ltd. April 6, 1964 [April 4, 1963], No. 13381/63. Heading H4F. In a colour television camera arrangement which produces a signal having a component representing sequential line information pertaining to different colours, as for example happens in the Secam system, an optical system projects different colour images of a scene on to the sensitive surface of a camera tube and the images are scanned by common scanning means to provide discrete colour signals. In the arrangement of Fig. 1 a lens system 10 focuses the scene on the target of a pick-up camera tube 11 which produces the luminance signal. Part of the light from lens 10 is diverted by halfsilvered mirror 12 to dichroic mirrors 13 and 15. Dichroic mirror 13 reflects the blue content of the scene and passes the red and green contents to mirror 15 which reflects the red content and passes the green. The blue content image is focussed by a cylindrical lens 14 which increases the aspect ratio, on to the upper half of the target of a camera tube 17. The red content image is similarly increased in aspect ratio and focused on the lower half of the target. Trimming filters may be included in the optical paths to correct the colour balance. The composite image on the target is scanned so that a signal output is produced consisting of line information taken alternatively from the two images. In the arrangement of Fig. 1 this signal output is produced by scanning first one line of one image and then a line of the other image. This necessitates a signal at line scanning frequency, which deflects the scanning beam in tube 17 vertically by the height of one image on alternate line scans. In the arrangement of Fig. 2 (not shown), one of the images is scanned and stored, via a switch 18 in a store 19. The other image is then scanned and the line output fed to switch 20. Switch 20 acts to pass to its output, lines alternately from the stored image and the directly scanned image. By using a single camera tube for both colour images registration difficulties are overcome. Two separate optical systems may be used for the luminance and colour tubes.

Abstract: 1,169,123. Drying cellulose films. E. I. DU PONT DE NEMOURS & CO. 21 March, 1968 [21 March, 1967], No. 13727/68. Heading B5B. [Also in Division F4] A method of drying gel-regenerated cellulose film containing up to 350% by wt. moisture based on the free cellulose content of the film to a moisture content of 2-8% by wt. comprises passing the film over drying rolls and releasing the tension in the film in at least 4 steps such that the film shrinks between 5-11% before 95% by wt. of the initial moisture content is removed, the film always being under tension sufficient to maintain it in contact with the rolls. The film preferably shrinks 3% before 40% of the moisture is removed. In the embodiment shown the cellulose film 10 e.g. produced from cellulose xanthate or cuprammonium cellulose, after being passed through liquid treating baths to wash, desulphurize, bleach and plasticise it, is passed over drying rolls R 1  &c. (e.g. steam or water heated rolls) enclosed in a housing through which warm air is circulated and from which moist air is exhausted. To achieve the desired above mentioned shrinkage the tension build-up in the film is reduced by reducing the peripheral speed of the rolls in the direction of film travel. In the final stages of drying the film is subjected to slight stretching.

Filed: 1917-09-26
Abstract: 118,703. Johansen, J. C., and Johansen (nÚe Hutchins), A. Sept. 26, 1917. Massage and vibratory treatment. -In apparatus in which movement of the applicators is produced by eccentrics, eccentrically - mounted weights, &c., means are provided whereby the throw of the eccentrics may be adjusted during operation, by an axial movement of a part of the mechanism. In the device shown in Fig. 1, the power-driven shaft 1 has mounted thereon two eccentrics 2, 3<a>, the inner one being secured to the shaft 1, and the outer serving to reciprocate the applicator head 4. The relative positions of the eccentrics are adjusted by the longitudinal movement of a screw 7 which passes through a slot 8<a> in the casing and moves a sleeve 5 along the shaft 1, a helical groove 5<a> engaging a pin 1<a >on the shaft 1 and serving to rotate the eccentric 2, thereby altering the effective throw of the combined eccentrics. Rotation of the eccentric 3<a> relative to the sleeve 5 is prevented by a slotted tube 3 secured thereto, which engages a pin 5<b> on the sleeve. A clamping-nut 7<a> serves to retain the device in the adjusted position. In a modification, Fig. 3, adapted to a rocking motion of the applicator, the holder 18 is pivoted at 19 to the front plate 14<a> of the casing 14, movement of an inner sleeve 11 effecting adjustment of the outer eccentric 17 through a sleeve 12 secured to the driven shaft 10. A helical groove 12<b> in the sleeve 12 causes the rotation through a pin 15a of a sleeve 15 mounted on a shaft 13 and connected by a slotted head 15<b> to a pin 17<a> on the eccentric 17, connexion between the parts 12, 13 being effected by a pin 13<b> and a slot 12<a>. Eccentrically-mounted weights may replace the eccentrics in these forms of apparatus. When a circular motion, in addition to the oscillating motion, is required, the inner eccentric rotates within a slot carried by an eccentricallypivoted disk secured to a sleeve, adjustment of which is effected in the manner shown in Fig. 3. An alternative means for producing the axial displacement comprises an external sleeve screwed on the interior to engage threads on a projecting part of a sleeve connected to the part to be adjusted. This device is described as applied to means for giving a circular conical motion to the application.

According to the invention a compartment f is provided below the table top in which the balls collect after passing through the goals, until a pivoted shutter p controlled by coin-freed mechanism is released. The confining walls at opposite sides of the table consist of rails carried upon vertical rods h. The playing surface rises slightly towards the ends and sides to prevent the ball resting in inaccessible positions. Coil springs j return the rods after sliding movement. The balls may be released from the shutter p by placing two pennies in slots t, Fig. 5, in a plunger u and pressing in the plunger. Over-size coins will not enter the slots, and under-size coins fall through to a return coin slot w, Fig. 2. Coins of correct size pass over a projection x, Fig. 8, when the plunger u is pressed in,. and 'drop down a coin slot 13. The inward movement of the plunger causes a fork 15 thereon to raise the shutter p and allow the balls to pass to a trough q. A pin 20 also operates a counter 28. If the plunger u is pressed in without first inserting the coins, two spring-pressed catches 21, Fig. 5, enter the slots t and prevent an effective movement of the plunger to liberate the balls.
