Title: Television pick-up and display system
IPC: H04N7/18
Filed: 1975-02-28
Abstract: 1499888 Television systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 Feb 1975 [4 March 1974] 8435/75 Heading H4F The system employs a display unit which operates according to a standard employing two interlaced line-scanning rasters and which receives an image signal from a pick-up unit either directly or via a store. In a known system of this type two fields are stored for display in the normal manner. In the present system, however, when the image signal is to be stored a sync. pulse generator is switched to cause the pick-up unit to produce a line scanning raster which has an integral number of lines instead of the fractional number produced when it feeds the display directly. A single such field is stored and is read out repeatedly to the display. The pick-up unit, e.g. a vidicon, may view an object illuminated by light, infra-red radiation, or X-rays, e.g. for surveillance or medical purposes. If the object is subjected to continuous illumination the pick-up unit feeds the display directly for interlaced display in the normal manner. Alternatively, if the object is to be illuminated only briefly, e.g. by X-rays generated in the blanking period preceding a raster, the display is fed by the store. In this instance the field sync. generator is switched to ensure that there is an integral number of lines in the raster, i.e. the raster contains an odd number of half lines more or less than the fractional number of lines in the normal raster. As only a single raster is stored the display is non-interlaced and will be free of flicker at frame frequency even if the object was moving when scanned. In one arrangement the sync. pulse generator (Fig. 2, not shown) includes a crystal oscillator (13), or an oscillator locked to the mains frequency, having a frequency 2n times the line frequency. The oscillator output is divided by n to provide a signal at twice the frequency and then by 2 to give a line frequency signal (H) to the pick-up unit. The twice line frequency signal is fed to a circuit including a gate (17) and divider (16), to provide field sync. pulses (Vc) when the pick-up feeds the display directly. The circuit has a selectively operable feed-back path from the output of the divider to the gate, the path including a differentiator (22, 23) and bi-stable (18), so that when rendered operative one pulse of the twice line frequency signal is prevented from reaching the divider, whereby the period of the field sync. pulses is extended by the duration of half a line to ensure that the raster now contains an integral number of lines.

Title: Apparatus for forming stacks of a predetermined number of flat workpieces
IPC: B65H29/68
Filed: 1974-02-26
Abstract: 1462078 Packaging machines; sheet ordering apparatus WINDMOLLER & HOLSCHER 26 Feb 1974 [8 March 1973] 8661/74 Headings B8C and B8R In a machine for providing a series of stacks of flat superposed workpieces, supply conveyer 5 delivers workpieces to a slower moving conveyer 7 in an overlapping formation due to the velocity difference, the flow of workpieces being interrupted, after a predetermined number have passed, by brake means operative to move downstream at the same speed as conveyer 7, while the conveying run of the conveyer extends at that speed. During this interruption, workpieces below the brake means are moving on to a further conveyer 8 moving faster than conveyer 7 to deposit workpieces at a stacking section 9 on a final conveyer 31 to accurate stacking between a vertically reciprocating abutment 32 and an oscillating slide 33. The belt runs 7<SP>1</SP>, and 8<SP>1</SP> of conveyers 7 and 8 are driven by rollers 16 and 17 respectively, and pass over rollers 18, 19, 20, 21. Each belt is led through a U-shaped loop on a carriage 22 movable on wheels 23 in a trackway parallel to the conveyers. When a clamp 37 on carriage 22 operates to clamp belt 7<SP>1</SP>, the carriage is carried downstream with the belt so extending the effective length of the conveyer 7. Clamp 37 is actuated by control device 4 in response to signals from a workpiece counter 3. Movement of carriage 22 stops feed of workpieces to conveyer 8 via roller 19 and gravity pressure roll 29, as roller 19 no longer turns. When conveyer 8 is cleared, carriage 22 is returned to the upstream end of conveyer 7 by a chain drive 41 actuated by device 4. Other systems for changing the length of the conveyer runs as carriage 22 moves are disclosed.

Title: Improvements in or relating to polythene films
IPC: B29C59/00
Filed: 1945-04-09
Abstract: Preformed polythene films are subjected on one or both sides to a superficial treatment with chlorine.  Films of good heat-sealing properties are obtained by chlorination in the dark or in the presence of a liquid medium preferably such that the film contains 25-100 mgms. of chlorine per 100 sq. cms. surface area.  Chlorine saturated with carbon tetrachloride vapour may be used. Chlorination may be carried out in a liquid medium such as water by passing chlorine therethrough.  Other liquid media such as trichloracetic acid or carbon tetrachloride at low temperatures may be used.  Films of high surface hardness may be produced by chlorination in an illuminated zone in the absence of liquid media.  Films produced as above have increased dye affinities and may be printed.  In an example, a polythene film is chlorinated for 5 minutes in a slow stream of chlorine while subjected to actinic light radiations.  The resulting product may be heat sealed at temperatures below 100 DEG C.  In the second example, a polythene film is passed slowly through a chamber filled with chlorine so that it is chlorinated for a period of 15 minutes at 30 DEG  C.  The product can be sealed at temperatures of 70-90 DEG  C. Specifications 474,426 and 481,515 are referred to.
