Abstract: 1300984 Duplicating magnetic tapes AMPEX CORP 19 Nov 1970 [20 Nov 1969] 55119/70 Heading G5R A recorder 10a, Fig. 3 has its heads wheel 12a, rotated in a sense 29a opposite to that of the wheel 12 of a conventional recorder 10, Fig. 1 in order that the slopes of the tracks 23a recorded on the tape 11a will be mirror images about a transverse plane of conventionally recorded tracks 23; the master tape 11a produced is then suitable for the contact printing of slave tapes for playback in conventional recorders. In order to obtain the desired scanning sequence when the slave tape is played back, the heads 1-4 of wheel 12a are arranged in a different sequence compared with the arrangement on the wheel 12 of the playback recorder; in addition, the control, cue erase and record, audio erase and record, heads 46a, 49a, 48a, 43a, 42a, respectively and the vacuum tape guide 14a are all in mirror image positions about a longitudinal plane relative to the corresponding positions in the recorder 10. Contact printing is effected by winding the master and slave tapes, emulsion face to emulsion face, on a reel and applying a transfer field to the whole reel (Fig. 6, not shown), in which case some re-recording of the longitudinal tracks may be necessary (Fig. 7, not shown), or by running the tapes through a field confined to a small region.

Filed: 1972-12-14
Abstract: 1397459 Fastener driving apparatus HILTI AG 14 Dec 1972 [4 Jan 1972] 57748/72 Heading B4C A device for securing an identity plate to a metal billet &c. comprises a fastener driving tool having means to retain a plate in front of its muzzle and means moveable relative to the muzzle to feed a plate from a supply container associated with the tool to a position in front of the nuzzle as the latter is withdrawn from the driving position. The apparatus described is supported by a carriage 2 from a frame (3) Fig. 1 (not shown) to one side of the path of the billets 4 for movement towards and away from the path. A cartridge operated driving tool 5 has a muzzle portion moveable relative to the tool body and fitted with magnets 34 to retain an identity plate 14a while it advances to engage the plate with a billet 4 and secure it with a nail N. Slidably mounted below the tool is a holder 7 for a plate magazine 8, the plates 14 being stacked in overlapping relationship, Figs. 2, 6, with projections 41 engaging rear ends of adjacent plates so that the whole stack may be urged forward by a slider 11 with a step 13 contacting the lowest plate. A coiled strip spring 12 biases the slider which may be withdrawn by a handle 38 to permit reloading. The plate feed device comprises levers 23 pivoted on opposite sides of the holder 7 and joined by a plate 31, Fig. 5. The levers are biased towards the position of Fig. 7 by springs 26 where the leading end of the uppermost plate 14a is engaged by pivoted spring biased jaws 45. The holder 7 is drawn to a retracted position by springs 9 when the tool 5 is advanced to secure a plate, Fig. 7, but when the carriage retracts the tool, the holder abuts the frame 3 so that the tool moves along the holder and a noze 27 engages one of the levers 23 to swing the feed device to the Fig. 2 position. The plate 14a is pivoted about the projection 41 of the preceding plate 14, Fig. 6, to lie across the tool muzzle and be retained by the magnets 34 when the tool is again advanced. The plates may be retained in the magazine by leaf springs or magnets (not illustrated). The feeder jaws could be adjustable for different sizes of plate. The plates could be fed by a sliding member instead of by the means shown. They could be corrugated for stiffness.

Title: Method of and apparatus for transmitting colour television pictures
IPC: H04N9/69
Filed: 1971-12-13
Abstract: 1373966 Television FERNSEH GmbH 13 Dec 1971 [16 Dec 1970] 57831/71 Heading H4F Luminance signals derived from colour television pictures with a large contrast range are transmitted through one or more channels A, B and control signals derived from the luminance signals are used to control the contrast ratio of the latter only when the control signal exceeds a predetermined threshold value. As shown, channel A contains a linear picture amplifier 3 and channel B a gamma stage 4 with amplitudedependent amplification. Part of the input signal is passed through a separating stage 6 to an integrator 7, 8 to provide a voltage signal dependent upon the mean value of the incoming signal over several picture periods. If the voltage signal exceeds the threshold value of threshold stage 9 a control signal is passed to gamma stage 4 to cause increased amplification in shadow areas and reduced amplification in light areas. The outputs from channels A and B are mixed in selectable proportions in mixer 2. In a modification, Fig. 2 (not shown), the control signal is used to adjust the mixer instead of the gamma stage.

The magnets 15 are circumferentially arranged in a disc 14 keyed to the driving shaft 1. In the clutch engaged position, as shown, the flux paths of the magnets are completed by a series of segmental plates 16 secured to a non-magnetic carrier plate 17 which is circumferentially adjustable within the driving carrier disc 7. Circumferential adjustment of the segmental plates 16 relative to the magnets 15 adjust the clutch engaging pressure. On overload the ball 10 rides out of the recess 12 and moves the carrier 7, 8 right for clutch disengagement. The carrier 7, 8 is held in the clutch disengaged position by the magnets 15, completing their flux path through the carrier disc 8. The clutch is re-engaged manually by a lever 20 which may also be used to disengage the clutch manually. The driving carrier 7, 8 is connected to a disc 3 fast with the driving shaft 1 by a series of tangential leaf springs 5.

Further cooling of the segments, even complete solidification may be obtained by allowing the segments to remain in the bath the appropriate time before collection by the paddle-wheel 120 and/or auxiliary paddle-wheels (140, 150, Fig. 4). Alternatively, further cooling may be obtained by employing a paddle-wheel (280) to feed the segments along a ziz-zag water course formed by vertically spaced apart trays (240-242). The cooling medium is recirculated and chilled by a refrigerator. The segments may be pillow-shaped (Figs. 5-7).
