Title: Punching apparatus
IPC: B21D28/14
Filed: 1965-08-17
Abstract: 1,122,286. Sub-press mechanism. MINNIE PUNCH & DIE CO. Inc. 17 Aug., 1965 [2 Nov., 1964; 16 Nov., 1964], No. 35304/65. Heading B3W. A sub-set comprises a magnesium punch. plate 4, a die-plate 6 and guide pins 8. The pins 8 are retained in bushes 12 in the punchplate 4 by circlips 10 and slide in bushes 14 in the die-plate 6. The plates are urged apart by springs 18 and the movement is limited by circlips 16. By this construction the guide pins are made easily removable. The tool shown is a combined blanking and piercing set and includes a blanking die 32 attached to the punch-plate and a blanking punch 56 attached to the dieplate 6. An ejector plate 34 in the blanking die 32 is acted on by disc spring assemblies 29 through pins 36. The movement of the ejector plate is limited by studs (49), Fig. 6 (not shown). The spring assemblies 29 are contained in housings 40 and can be removed by loosening a screw 52 which locks a clamping plate 50. A stripper plate 37 surrounds the blanking punch 56 and is acted on by disc spring assemblies contained in cylinders 28 which also support the die-plate. The springs act on pins 35 which pass through the die-plate. Above each pin 35 a head 39 is positioned on the upper face of the stripper 37 and secured to the pin by a screw 41, Fig. 8. The thickness of the head is at least twice the thickness of the work material 54, so that as the punch-plate 4 moves upward the component part is ejected from the blanking die and then the webbing is stripped from the punch. In a modification. Figs. 10 and 11 (not shown), the ejector plate (127) which corresponds to the ejector-plate 27 of Fig. 2, is held in position in the blanking die by pins (128) which pass through a punch-plate (115) and a backing-plate (124). The pins are acted on by a further plate (132) which is loaded by disc springs (138). There are projecting bosses (139) on the plate (132) which align the disc springs and which enter apertures in a striker plate (131). In both the embodiments described the ejector actuating assembly can be removed from the die set for use in a similar type of set.

Title: Treatment of polyethylene film
IPC: B29C59/10
Filed: 1956-11-21
Abstract: <PICT:0842104/IV(a)/1> To improve the printability of one or both surfaces of polyethylene film, the film is subjected to a corona discharge between electrodes supplied with alternating potential and having a capacitor effectively in series with the electrodes and the source of electricity; the inclusion of the capacitor reduces the variation of current between different areas of the electrodes so that a more nearly uniform treatment of the film is obtained when large areas of film are treated.  As shown, polyethylene film 11 is guided onto a rotating drum 13 covered with a layer of dielectric material 14 to prevent arc-over and provided with a slip ring and brush 16 for electrical contact.  A stator 17 and the drum are connected to an alternating potential source 18 and a capacitor 22 is connected in series with the drum.  The electrodes may comprise a pair of parallel plates and the capacitor may be in series with the primary winding of a step-up transformer, the secondary of which provides the potential to the electrodes.  The film undergoing treatment may have a width of several feet and the area being treated at any instant be several square feet. Specification 715,914 is referred to.

Abstract: 1,080,469. Coating by extrusion. L. ZANINI. Sept. 2, 1964 [Jan. 24, 1964], No. 35894/64. Heading B5A. A method of producing a coating of plastics material on an elongated body of non-circular cross-section comprises passing the elongated body through an extruder nozzle, extruding a plastics tube of substantially circular crosssection from the nozzle, bringing the tube into contact with the body at a distance from the nozzle, and passing the body and the tube through a shaping device which imparts to the tube an outer cross-sectional shape and simultaneously cools it. A wooden rod 1 is milled to a desired cross-sectional profile in a milling device 3 (Fig. 1, not shown), and passed through a priming device (4), a heating device (5), and a guide 27 in an extruder head 6. Plastics material is fed to the extruder head 6 via passages 14 past heating devices 15 and through filters 18, 19 heated by steam or electricity, and passes from a chamber 22 in the extruder head 6 through an annular die 28, 29. The extruded tube 32 is brought into contact with the rod 1 in a profiling device 11 spaced from the extruder head 6. Vapours emitted by the wooden rod 1 are withdrawn by suction from the space 34 between the rod 1 and the extruded tube 32 and in front of the profiling means 11. Plastics material having a colour different from that supplied through the filters 18, 19 may be introduced through a passage 42 to a space between external fins 41 (Fig. 3a, not shown) on the guide 27, to be carried into the main stream of extruded material. Several such passages may be provided for injecting materials of various colours. In the profiling means 11 the plastics tube 32 is drawn by suction against a guide member 48 (Fig. 5, not shown) to shape it to the desired cross-section which may differ from that of the rod 1.

[Class 38 (iv).] The current supplied to a heater 112 is regulated by varying the effective turns of the transformer secondary. 27 by the rotation of a drum carrying a stepped contact strip 38. This drum is mounted on the same shaft as two more drums bearing strips 32, 34 and two motors 36, 37 arranged for operation in opposite directions. When the mercury rises in a thermostat 117, the circuits of relay switches 28 are completed one by one causing them to make contacts 29 and break contacts 30 and thus cause motor 36 to rotate the drums a distance proportional to the number of switches operated. When the mercury falls, contacts 29 are broken and contacts 30 made causing motor 37 to rotate the drums in an analogous manner to motor 36 but in the opposite direction.

Abstract: 1361457 Film scanning EASTMAN KODAK CO 3 Aug 1971 [3 Aug 1970] 36404/71 Heading H4F  The scanning raster of a flying spot scanner (1, Fig. 1, not shown) scanning a continuously moving film is moved vertically to follow the moving film frames in response to a signal SP detected by a photodetector (46) detecting the movement of the sprocket holes of the film, or indicia recorded on the film. If the film. is stopped the flying spot scanner raster is automatically positioned for scanning a stationary frame. The detected film signal SP is fed to multivibrators 51, 54 and NAND gates 57, 58 to produce pulse signals A<SP>1</SP> and B<SP>1</SP>, each of half the frequency of signal SP, 180 degrees out of phase with each other, which are fed to respective sawtooth generators 61, 62 to produce sawtooth waveforms C, D, each of half the frequency of signal SP, and of amplitude such as to deflect the flying spot of the flying spot scanner over two film frame heights, waveforms C and D being 180 degrees out of phase with each other. Multivibrators 92, 93 receiving signals A<SP>1</SP>, B<SP>1</SP>, and television field frequency pulses LP, in combination with multivibrator 96 produce complementary signals E, F, each of which changes state at the occurrence of the first television field frequency pulse LP following the start of each film signal pulse SP. In one state of signal E it earths point 78, whereas in its other state it allows waveform C to pass to OR gate 80. Signals E and F cause gate 80 to pass a signal which is made up of alternate portions (alternately 2 and 3 television field periods long for a film speed of 24 frames per second) of sawtooth waveforms C and D, which signal is added at 87 to a television field frequency sawtooth waveform from generator 82, to provide the vertical deflection signal for the flying spot scanner. If the film frame rate changes differential amplifiers 65 and 67, and current source 70 automatically change the amplitudes of sawtooth signals C and D to give correct scanning. Circuit 73 responds to loss of flyback of signals C and D due to loss of signal SP when the film is stopped to produce a D.C. signal which is added to the output of generator 82 to correctly position the scanning raster.
