Title: Method and apparatus for printing on the surface of plastic hollow objects
IPC: B41F17/18
Filed: 1966-09-01
Abstract: 1,142,496. Printing on surface of plastic hollow Objects. E. I. VALYI. 1 Sept., 1966 [9 Sept., 1965], No. 39154/66. Heading B6C. Deformable plastic hollow objects are printed upon by a process which comprises filling the object with removable particulate material which is inert to the material of the walls of the object and which is of such a size that it remains unembedded in the walls after the printing process; evacuating the hollow object thus rigidifying the particulate material to form a support for the walls; printing on the surface of the object; releasing the vacuum and emptying the printed hollow object (see Fig. 1). Referring to Fig. 3, the hollow object or container 10 is filled with a particulate material 14, which is preferably of glass, metal or refractory beads, and is then vibrated or tamped to compact the material. A cap 15 is affixed to the threaded neck 12 of the container, this cap being provided with a tube 16 and a valve 17 connected to a vacuum source. Fig. 4 illustrates the filled and evacuated container 10 at the printing position, the opposed walls 11 being flattened between a printing cylinder 22 and a pressure roller 23 of an offset printing machine. After printing, the vacuum is released and the free-flowing particulate material removed under gravity by inverting container 10. If the particulate material is composed of magnetizable particles, e.g. iron or steel, rigidity of the container may be obtained by subjecting it to a magnetic field, subsequent de-magnetization facilitating removal of the particles after printing.

Title: Colour killer circuit for a pal colour-information-signal handling circuit
IPC: H04N9/70
Filed: 1970-08-18
Abstract: 1,271,786. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 18 Aug., 1970 [21 Aug., 1969], No. 39731/70. Heading H4F. A colour killer circuit for a PAL receiver comprises a " swinging " burst signal synchronous detector 49 to which a reference-signal from an active chrominance subcarrier generator 43 is supplied, the output of the detector being fed via a filter 67 which passes a signal having a frequency equal to half the line frequency to a detector circuit 73 which includes a minimumsignal-amplitude detector. The colour killer signal is derived from the detector circuit 73 and supplied to chrominance signal amplifier 15. With monochrome reception harmonics of the line frequency which lie immediately on either side of the chrominance subcarrier generator frequency produce a signal of half line frequency at the output of burst detector 49, which signal is amplitude modulated at a frequency equal to the difference between the generator frequency and the mean frequency of the two harmonics. Thus its amplitude becomes zero twice per period of the amplitude modulation and detection of the minimum amplitude of this amplitude fluctuation indicates that the obtained signal of half line frequency does not originate from a received colour signal but from a monochrome signal, only the presence of a steady signal of half line frequency at the output of the burst detector causing operation of chrominance signal amplifier 15. The detector 73 is so arranged that when the amplitude fluctuations occur the minimum-signal-amplitude appearing at output 75 maintains the chrominance signal amplifier 15 cut off.

Abstract: 1369793 Capping bottles METAL CLOSURES Ltd 24 Aug 1972 [27 Aug 1971] 40426/71 Heading B8T. A detachable rotary headset for an application head 1 of a bottle closing machine comprises a head block 53, with cylinders 55 arranged round its axis, each cylinder containing a pressure fluid operated piston 56 with torsion springs 60 to return it to its original position. The pistons 56 activate arms 57 carrying spindles 58 connected to thread roller arms 61 and skirt roller arms 62, carrying thread 63 and skirt rollers 64 respectively, the former being each mounted in a bearing sleeve 65 and the latter in an adjustable sleeve 71. The thread roller 63 is movable in relation to the arm 61 and is biased upward by means of compression spring 66, and the skirt roller is similarly biased with a spring 72. A lower pressure block 73, connected by a screw thread and needle bearing assembly 74, 75 to a hollow pressure stem 17 is adapted to reform the head of the closure with adjustable head pressure being applied to member 79 from the upper pressure block 13, activated by fluid pressure in cylinder 8 acting on piston 9. A cam and roller mechanism 7a, 107 cause cylinder 8 to move down enabling constant fluid pressure in the cylinder to operate piston 9 thereby bringing pressure to bear on block 73 through intermediate numbers 13, 17.  The application of fluid pressure to cylinder 8 is independent of the application of pressure leading to movement of the roller arms 61, 62, and head reforming occurs prior to radial pressure being applied to the closure skirt. Rotation of head block 53 causes rotation of rollers 63, 69 around bottle 3, the headset rotation being activated by a keyed connection to a drive spindle 31 driven by a gear 32. In a modification (not shown) the headset may be arranged so that the skirt and/or thread rollers can pivot on inclined or horizontal pins. A further modification (not shown) provides separate control of the fluid pressure to the skirt and thread rollers respectively by providing separate pressure passages to the respective cylinders in the headset.

Abstract: 1343715 Positional control VICTORY KIDDER Ltd 31 Aug 1971 [8 Sept 1970] 40551/71 Heading G1N In an apparatus for positioning plate and roller mechanisms of a printing press, the desired position is presented on a dial and converted into a voltage which is compared with a second voltage indicative of the instantaneous position of the members to provide an error signal to cause the driving of the members towards the desired position. As shown, a reference voltage derived from the output of a differential amplifier (200), Fig. 3, (not shown), having a resistance network (202) in one of its input circuits the value of which is altered by the dial, is combined with a voltage derived from a movable slide potentiometer indicative of the instantaneous position of the member. The combined signal is amplified at 54 and taken to the positive and negative inputs respectively of 2 further differential amplifiers 58, 60 to yield an output either across resistance 74 or 76 depending upon the polarity of the combined signal. The signal from amplifier 58 is adapted to gate S.C.R. 78 to enable triac 86 to enable a pneumatic or hydraulic valve to cause motion of the member in one direction, whereas that from amplifier 60 gates S. C.R. 80 and triac 94 for motion in the opposite direction. The signals are also used respectively to gate S.C.R. 104 and triac 108 and S.C.R. 114 and triac 118 to enable clutch valves on both sides of the member (the "operator" and the "gear" sides) to apply a drive, these parts of the circuits being interconnected as shown so as to move both sides of the member in one or other direction Relay contacts 120, 122 are provided which when operated remove the enabling power voltage from the valve(s). Under these conditions a remote controller may be used to supply power to a plurality of positioning stations according to a programme. The potentiometers moved by the members may have further resistances in series, Figs. 2a-2c (not shown) shunted by relay contacts which may be selectively operated in conditions when a mechanical constraint etc. necessitates modification of the feed-back signal.
