Title: Leak detector
IPC: G01N27/62
Filed: 1970-10-08
Abstract: 1330685 Molecular pumps SARGENTWELCH SCIENTIFIC CO 8 Oct 1970 [27 Oct 1969] 47858/70 Heading F1C [Also in Division G1] A leak detecting system comprises an evacuation pump 32 with an inlet for connection to a vessel to be tested and an outlet connected by a fore pump line 64 to a fore pump 62 the two pumps co-operating in use to evacuate the test vessel, a detector pump 36 with an inlet 56 connected to a low molecular weight gas detector 50 and an outlet 60 connected to the fore pump line 64, the evacuation pump 32 and detector pump 36 being a single turbomolecular pump having a pair of rotor and stator assemblies separated from each other by a substantially gas impermeable partition 44. When a high vacuum exists through the system (10 <SP>-6</SP> to 10<SP>-12</SP> torr in the low pressure regions of the molecular pumps), hydrogen or helium surrounding the test vessel enters the vessel through a leak (if present) and is pumped, together with other leaked in gases to the fore pump. At these low pressures, no set gas flow occurs in the analyser pump 36, but the low molecular weight gases H 2 , He accumulate dry diffusion at the low pressure end 86 of the analyser pump 36 and high molecular weight gases e.g. O 2  N 2  accumulate at the, relatively, high pressure end 88. The low molecular weight gases are thus concentrated and are detected by the mass spectrometer arranged to detect them thus increasing the sensitivity of the leak detector.

Title: Magnetic recording and reproducing system
IPC: G11B5/127
Filed: 1966-11-04
Abstract: 1,120,085. Magnetic tape erasing. SONY CORP. 4 Nov., 1966 [4 Nov., 1965 (2)], No. 49494/66. Heading G5R. A method of erasing portions of spaced recorded tracks oblique to the longitudinal axis of a magnetic tape comprises moving the tape along its longitudinal axis and in contact with an erase head having a gap disposed perpendicular to the longitudinal axis, and providing additional transverse movement between the tape and the erase gap at such a rate that the direction of erasing is parallel to the direction of the recorded tracks. One apparatus consists of an erase head 17, Fig. 2, having an erase gap 18 of length equal to the width of the tape 10 and driven by a screw 21 transversely of the moving tape at a rate such that the relative tape-head motion is along the oblique tracks 11. When the stage shown in the third diagram of Fig. 2 is reached, lateral traverse of the head is stopped while tape movement continues so that total erasure of all tracks is effected for a predetermined time. Thereafter, lateral traverse of the head is resumed in the same direction and at the same speed. In an alternative arrangement a stationary head 23, Fig. 4, having an erase gap 27, is surrounded by a non-magnetic cylinder 24 having an oblique slot 26 and rotated by a motor 28 so that the gap may be first incrementally exposed and then correspondingly obscured at appropriate stages of the process. Fig. 5 shows apparatus for recording control signals in tracks which are parallel to the main (e.g. video) tracks. Tape 38 is partially trained about two highly-polished stationary drum segments 31, 32, separated by a gap 33 in which rotates an intelligence-recording head 34, the tape being moved at constant speed. A head 39 for applying spaced control signals is mounted on drum segment 31. Signal and intelligence tracks, being parallel, may both be erased in one pass. The tape resulting from the Fig. 5 system also permits compensation for tracking errors caused by deviations in tape width.

Abstract: 1,058,006. Processing magnetically recorded signals. BRITISH BROADCASTING CORPORATION. Dec. 2, 1965 [Dec. 10, 1964], No. 50389/64. Heading G5R. To reduce blemishes on a reproduced picture due to drop-outs in playing back a tape, the signals, after passing a head changeover switch and head amplifier 10, are passed to a normal amplitude limiter and discriminator 11, where they are recovered from the FM carrier played back and, in the absence of serious drop-outs, are passed through a switch 27 to normal output means 12, 13. The signal, before limiting, is passed to two level detectors 20, 20a. If the drop-out is slight (6 dB or less) detector 20a does not operate switch 27, but detector 20 operates to switch the bridge 17 and isolate capacitor 18 from the output at 16. Due to the high timeconstant of 18 and 19 the output of 19 is the steady signal level at which onset of the dropout occurred. If, now, the drop-out becomes worse (typically 30 dB) detector 20a opens switch 27 and the stored level at the output of 19 is passed to the output means 12, 13 until recovery from the drop-out reinstates switch 27. A simpler embodiment, operative to " freeze " the output at all levels of drop-out is described also in the Provisional Specification.
