Filed: 1939-07-13
Abstract: 530,363. Spring upholstery. DAVIS, J. M. July 13, 1939, No. 20453. [Class 52 (iv)] [Also in Group XXII] Coiled springs are con nected together to form a spring interior for mattresses, cushions &c. by assembling an end row of springs on a support which is moved relatively to a second support into which parallel rows of springs are successively placed and attached to the previous row by the wires, the end row of transverse springs 9 is placed in a trough 12 and the springs secured together by a helical tie wire. The assembly is then placed in an inverted trough 13 which is fed upwards by a cable or chain 16, Another row of springs is then inserted in the trough 12 and attached to the previous row by a tie wire 1. The trough 13 is fed upwards step by step and between each step another row of springs is attached to the preceding row. The springs may be held in the trough 13 on short projections 18 or removable pins or one wall may carry pins and be removable or hinged. The trough 13 may be guided on posts 14, the extent of each movement being indicated by slotted bars co-operating with pegs on the cables or graduated uprights co-operating with pointers or with the guides 15 on the trough 13. A number of assemblies may be made by placing pairs of troughs in frames 32, Fig. 18, radiating from and preferably swung about a vertical column 19. Each frame may be pivoted about a vertical axis mounted between upper and lower axis radiating from the column. The tie wires may be formed with a series of lateral U-bends each limb of the bend being of S-form as shown in Fig. 3 and described in Specification 515,821.

Patent GB-777936-A (GB)
Title: Improvements in and relating to colour switching circuits including reflector type colour television receiver tubes
IPC: H04N9/16
Filed: 1953-07-23
Abstract: 777,936. Colour television tubes. GENERAL ELECTRIC CO. July 23, 1953 [July 24, 1952]. No. 20469/53. Class 39(1). [Also in Group XL(c)] The colour switching circuit of a cathode ray receiver of the reflex type is such that the colour switching voltage is applied between the gun on one hand and the reflector and screen electrodes on the other hand, while the potential difference between screen and reflector is always constant. In one form, Fig. 1 (not shown) the colour switching voltage is applied between the gun on one hand and to the second anode and reflector on the other hand, the second anode being connected through the metal cone to the screen. In a modification, Fig. 2, the circuit allows the average beam intensity to be increased when the beam strikes the red phosphor to compensate for the lower luminosity of the red phosphor as compared with the green and blue phosphors and differences between the luminosities of the green and blue phosphors can also be compensated in this manner. This is done by using a stepped colour switching waveform applied at 31, 32 so that due to top 41 the potential of the first anode varies relatively to the cathode and control electrode. In another form, Fig. 4, a condenser 43 helps to ensure that there is no varying potential component between the screen and reflector. The second anode 19 is connected by spring fingers to wall coating 14 and cylindrical insulators space and support the gun electrodes. Specifications 713,875 and 726,214 are referred to.

Title: Improvements in or relating to ironing machines
IPC: D06F65/08
Filed: 1959-06-15
Abstract: 854,872. Ironing-machines. IRONRITE Inc. June 15, 1959 [June 18, 1958], No. 20482/59. Class 138 (2). In an ironing-machine, movement of a rotatable ironing roll 26 towards and away from a stationary shoe 24 is effected by a cam 74 which is rotatable through 180 degrees at a time by coupling it through a clutch 82 to a motor 38. The cam 74 is mounted on a shaft 52 and bears on a spring 76 rigid with a tube 30 supporting the roll 26. A spring 78 maintains the spring 76 and cam 74 in contact. The clutch 82 comprises a sun-gear 62 (Fig. 5), planet gears 64, a planet carrier 72 (Fig. 4), a ring gear 68 and a yoke assembly 84 for selectively restraining either the ring gear or the carrier. The yoke assembly 84 comprises two legs 92, 100 interconnected, by a spring 97, the leg 92 being fixed to and the leg 100 rotatable on a shaft 86. When a projection 94 on leg 92 engages in either of two notches 96 in the carrier 72, the carrier is prevented from rotating, and the roll is held in either shoe-engaging or retracted position. By raising a control pad 110 (Fig. 2) pivoted at 112 adjacent a feed board 116, the shaft 86 is rotated to withdraw projection 94 from notch 96 and move a tooth 104 on leg 100 into engagement with teeth 70 on the outer side of ring gear 68. The ring gear 68 is thus held stationary and the carrier 72 rotated by means of the sun and planet gears. When the carrier 72 has rotated through 180 degrees the cam 74 has moved the roll 26 from one position to the other and projection 94 engages the other notch 96 to stop further rotation of the carrier 72 and cam 74. The control pad 110 is connected to the shaft 86 through the linkage shown in Fig. 2. The roll 26 is driven by the motor 40 through gearing in a housing 32, a shaft 34 in the tube 30, and gearing 36 in one of two arms 28 supporting the roll. Figs. 7 to 14 (not shown) illustrate modified forms of control members.

Title: Improvements relating to the generation of electrical signals representing colour components of an image
Inventor: PERKINS DENIS GORDON
IPC: H04N9/07
Filed: 1963-05-16
Abstract: 1,092,882. Colour television cameras. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 19, 1964 [May 16, 1963], No. 20563/64. Heading H4F. [Also in Division G2] Image light is focused on the target 3, Fig. 1, of a pick-up tube 2 by a lens 4 and is divided into its component colours by means of two filter gratings 1 which are spaced from each other and are located in the path of the convergent light from the exit pupil of lens to the target in a position so that they are not in focus on the target surface. The Specification discusses the relationships between the grating constants and their spacings from the target which are necessary to produce desired colour shadow patterns whereby the colour components may be distinguished. A first arrangement, Fig. 4, is concerned with the generation of simultaneous colour signals and uses gratings as shown at 9 and 10 with strips disposed at right-angles to the line scanning direction and formed in a repeating sequence of white (W), yellow (Y), cyan (C) and green (G). The gratings allow green light to pass without modification but impose line structures on the red and blue light with the blue pattern period half that of the red. As a consequence, during scanning, green appears as a conventional video signal whilst red and blue appear simultaneously as carrier signals with frequencies in the ratio 1 : 2: Fig. 5 (not shown) illustrates a modification in which the second grating 12 is formed with only white (W) and green or black strips. A second arrangement, Fig. 6, uses gratings as shown at 13 and 14 (the unreferenced shaded strips being black) and produces a shadow pattern giving a light distribution along a scanning line as shown at (c) whereby dot sequential signals are produced. A third arrangement, Fig. 7, is employed for the generation of line-sequential colour signals and utilizes horizontal strip gratings as shown at (a). The green strips are uninterrupted, but the red and blue strips are interrupted by black section as shown shaded. The number of black sections in the blue strips is twice that in the red strips. The vertical light distribution is as shown at (b), the intensity peaks corresponding to scanning line spacing. Red, green and blue signals thus appear in sequence at line rate, the red and blue signals being carrier signals which are distingushed in frequency. This third arrangement may be utilized in the apparatus described in Specification 1,092,881 where the line-sequential signals are subsequently converted to simultaneous signals. The gratings may be in the form of lenticulations which have a focusing effect.
