Abstract: A helical scan magnetic recording and reproducing system is of the type where time compressed audio signals are recorded in extensions of the video tracks. In orderto avoid a time delay of the reproduced audio relative to its original relationship to the video, additional audio playback heads (S1, S2) are located on the helical scanner so as to read the audio information sufficiently in advance of the video heads (P1, P2) to allow restoration of the original audio/video synchronism. The audio is recovered by a switch (26), de-interleaving circuit (28) - and time expansion circuits (30, 32). The arrangement allows full flexibility in audio editing even when the recorded audio signals are digitally encoded and interleaved. In order to avoid a time delay of the reproduced audio relative to the video when played back, additional audio recording heads are located on the helical scanner so as to record the audio information on tracks that when played back are reproduced sufficiently in advance of the video to allow restoration of the original audio/ video synchronism. The arrangement can thus can be employed to produce prerecorded tapes having time advanced audio such that synchronous audio/video is reproduced on conventional playback reproducing systems.

Abstract: O A display arrangement utilises a fluorescent screen 3 to provide readily alterable bright displays. The arrangement can provide a fairly large display surface, but can be of very small thickness. It contains electron emissive cathodes 5, and field electrodes 7 positioned closely adjacent to the cathode to control the emission of free electrons. Electrons which are freely emitted are accelerated to a mesh electrode 4 which is held at a modest positive voltage. A fluorescent screen 3 having a positive potential of several thousand volts is positioned closely in front of the mesh electrode. The preferred embodiments of the invention, a number of separate cathodes and/or separate field electrodes are provided, so that selected regions of the screen can be illuminated to provide desired display patterns. Individual regions of the screen can be switched on and off (i.e. rendered bright or dark) by the application of very low switching potentials to the field electrodes and/or the cathodes.

Abstract: A measuring system is described which includes a scale which defines a measuring graduation and an array of reference marks. The reference marks are positioned at predetermined absolute positions with respect to the graduation and are used to generate reproduceable electric reference control pulses. In order to identify each of the reference marks a serially allocated code mark is provided which is made up of at least one nonzero code mark segment. Each nonzero code mark segment agrees in spatial pattern with the nonzero associated reference mark in the measuring direction. In order to distinguish nonzero code mark segments from reference marks, the width of the nonzero code mark segments perpendicular to the measuring direction is made less than the width of the reference marks.

According to the invention the heating effect (P) of the heating equipment (1) is governed in accordance with the room temperature (T h ) and time (t) so that upon the room temperature falling below the corresponding temperature setting value (T a ) which is being maintained, the surface temperature (Tp) of the heating equipment is raised by a correspondingly calculated known value (ΔT 1 ) for a known time period (6t), the regulation cycle being thereafter repeated.

Abstract: The relase mechanism of an electronic timelock employs two bistable electromagnetic actuators 1 and 2 to control the "on-guard" and "off-guard" conditions of the lock, each actuator comprising an element 4 of ferro-magnetic material whose magnetic polarity serves as the "memory" of whether the lock is in an on- or off-guard period and which polarity is reversed by single magnetising pulses through the associated coils 3 when each successive on-and off-guard period is programmed to commence. 
     More particularly, when on-guard the coils 3 are pulsed in one direction to magnetise the elements 4 so that they are attracted by poles P1 of the field magnets 5. In this condition they block a beam 10 which is pinned at 11 to a bolt 8 which in turn blocks a bar 6 which is attached to the door's boltwork. When off-guard the coils 3 are pulsed in the opposite direction to reverse the magnetisation of elements 4 so that they are attracted by poles P2 of the magnets 5. This enables the beam 10 to be lifted with the bolt 8 as a spring snib 12 on the bolt rides up a notch 19 in the bar 6 when the latter is retracted. If the bar6 isforced when the mechanism is locked the snib 19 is turned until a face 20 on the bar is blocked by the bolt 8, thus limiting the upward force which can be applied through the beam 10 to the elements 4. If one actuator should for any reason fail in the on-guard position the lock can still be released when the other actuator switches to the off-guard position, by pivotal movement of the beam 10.

Abstract: A lead frame that is suited for use on array types of integrated circuit packages to provide a high degree of compliance for absorbing mechanical stress induced by thermal changes includes a series of individual terminal elements that are connected in a strip form by means of break tabs disposed between adjacent elements. Each terminal element provides two spaced, generally parallel mounting surfaces that are resiliently connected to one another by means of an integral intermediate section. While the terminal elements are interconnected in strip form, one of the mounting surfaces of each element can be bonded to an associated attachment region on the semiconductor substrate. After all of the terminals of the strip have been so bonded, the break tabs between adjacent terminals can be removed to thereby separate the terminals from one another. The package which then results contains discrete compliant terminals which are suitable for subsequent surface attachment to the printed circuit board.
