Abstract: 1281211 Decorative articles CONSOLIDATED PRODUCTIONS Inc 24 July 1969 37381/69 Heading B6G As shown in Figs. 1-4, plastics articles are produced by (1) helically winding a plurality of overlapping layers of twisted plastics strip(s) 7 on a rotating mandrel 11 having two longitudinal slots 11b and 11c and a single longitudinal slot 11d, the strip(s) being guided to the mandrel by guide plate 12 mounted on longitudinally moving carriage 61, (2) radially heat sealing together the helically wound plastics along a relatively narrow longitudinal path e.g. by moving the wound mandrel 11a on holder 16 towards heat sealing device 17 carrying a double row of teeth 18 which puncture the wound plastics material and enter slots 11b and 11c and (3) longitudinally slitting all of the layers of helically wound plastics using slot 11d as a guide means so that after being freed from the mandrel and suitable shaking unsealed layers of plastics project radially from a centre core comprising the heat-sealed portion. As shown in Fig. 2 a reinforcing element, e.g. a wire or plastics band reinforced with a fibreglass, may be laid on top of the wound plastics material over centre ridge 15 between the two slots of mandrel 11 which has been stopped, the mandrel set in motion again and the carriage returned to its original position to encompass the reinforcing element. The plastics may be polyethylene. The article may be a rigid or flexible garland, a pompon, a snake, a Christmas tree, a rug; an item, e.g. a dog, may be constructed from a number of wire reinforced articles. Two tone effects may be achieved by using two carriages supplying differently coloured strips. Apparatus for producing the wound mandrel (Figs. 6 and 7, not shown), and for puncturing and heat sealing the wound mandrel (Figs. 11 and 12, not shown) is described in detail. Certain portions of the plastics material may extend radially beyond the main body portion of the article (Fig. 20, not shown) this effect being achieved by attaching to carriage 61 guide means for plastics strip adapted to swing in a pendulum manner as the carriage reciprocates so that additional strips of plastics are applied at a greater angularity over the helically wound mandrel (Fig. 24, not shown). In other embodiments: (a) a mandrel for producing two separate plastics articles is provided with two heat sealing slots and two cutting slots (Fig. 25, not shown; (b) a mandrel for producing a ruglike article has a cross-sectional polygonal shape provided with a number of heat sealing slats and a single corner cutting slot (Figs. 26 and 27, not shown); (c) a mandrel for producing a Christmas tree has a general, right-triangle cross-sectional configuration tapering in thickness (Figures 28 and 29, not shown); and (d) a mandrel of variable cross-section for producing a snake is provided (Figs. 30, not shown).

The arm 1a is secured to an angle member 4 projecting through the table 3, and the arm 1b is resilient and secured to a support 2. When an electromagnet 5 is energized the arm la is forced to the right into the position of Fig. 1, flexing the arm 1b and causing the joint 1c to move upwardly and to the right so that documents are deflected downwards. On de-energization of the magnet, the switch returns to the position of Fig. 3. Movement of the switch is permitted by a portion 8a of the guide-plate 8 being bent upwards. Alternatively, the magnet may be in the region of the plate portion 8a. Deflected documents are guided on to the support 9 by cords 10. Each document is moved against a stop 13 by a driven roller 12 mounted on an arm pivoted at 15, and as the stack grows the roller is raised and actuates a switch 16 to lift a locking-plate 18 and allow the support 9 to fall under the weight of the stack 14.

A second conveyor 23 is located above the main conveyor 11 and directly below a hopper 22 containing soil 28 the height of which inside the hopper determines the rate of flow of the soil and is controlled by a switch 27 which controls the drive of a conveyor 30 which carries soil to the hopper 26. A scraper bar 36 removes soil from belt 23 and scrapes excess soil from the top of each pot to a pre-determined level. The belt 23 is height adjustable by means of a jack 38 and moves at substantially the same speed as belt 11 so that pots 14 pass between the two belts and the soil is compacted by the bottom run 37 of the belt 23. Guides 44 take the pots 14 across a narrow bridge which allows spilled soil to fall into casing 48 from whence it is conveyed on belt 54 back into hopper 26. As each pot 14 passes over bridge 47 it is taken up by a conveyor belt 57. Each pot 14 is engaged by guides 61 and has a hole punched in the soil therein by an adjustable punch 67 operated by a motor 63 and actuated by switch 62 which itself is actuated by the pot. After punching, the pot 14 is moved along by conveyor 57 to have cuttings, seedlings or the like planted therein.

Title: Improvements in and relating to colour television and like apparatus
IPC: H04N9/24
Filed: 1960-11-23
Abstract: 912,312. Television. PHILCO CORPORATION. Nov. 23, 1960 [Nov. 23, 1959], No. 40268/60. Class 40 (3). In a colour television receiver utilizing a beam indexing tube 10 (Fig. 1) having auxiliary (run-in) indexing stripes 40 (Figs. 1 and 2) of pitch n outside the picture area and conventional indexing stripes 44 of pitch m associated with the colour phosphor stripes 30, 32, 34, the beam of the tube is modulated by a signal of   frequency (m/n - 1) fw (where fw is the "writing-   frequency " and m and n are integers greater m than unity and - is also greater than unity) n from an oscillator 52 which is pulsed " on " only during the scanning of the " run-in "  stripes 40 so that the effective indexing signals produced by scanning the stripes 40 have the   same frequency m/n #w, as the indexing signals produced by scanning the stripes 44 during which period the beam is not modulated by oscillator 52. A single amplifier 50 tuned to the   frequency m/n #w then suffices for both sets of   indexing signals. During the scanning of the " run-in " stripes the phase and frequency of the " writing-frequency " oscillator 56 is controlled by the output of mixer 54 which derives the difference between the outputs of amplifiers 50 and oscillator 52. During the picture area scanning period oscillator 56 is controlled by the output of mixer 64 (gated " on " during this period by a pulse from generator 58), which derives the difference between the multiplied outputs of oscillator 56 itself and amplifier 50. The phase of the " writing-frequency " oscillator 56 is thus initially established absolutely by the stripes 40 during the " run-in " period and then subsequently controlled during the picture area scanning period by the rate of scanning the indexing stripes 44. The output of oscillator 56 is then employed to control the application of chrominance information in the form of a phase and amplitude modulated sub-carrier wave to the modulator electrode 14 of the tube. This is brought about by combining in mixer 70 the outputs of the further mixers 66, 68 to which are respectively supplied the output of multiplier 60 together with the chrominance subcarrier wave and the output of multiplier 62 together with a reference wave of sub-carrier frequency. The output of mixer 70 then comprises a wave at the " writing-frequency "  modulated by the chrominance information such that the " colour phase " thereof corresponds at any instant with the position of the scanning beam relative to the colour phosphor stripes 32 ... 34. This wave is supplied to the modulator electrode 14 together with the separately derived luminance information.
