[Class 20 (ii).] The head 1 of a pit prop is normally supported on the lower arm 10 of a crankec lever which is pivotally mount ed on the body of the prop and to one side of a vertical central plane thereof, and the other arm 11 of the lever is adapted to be releasably locked to the head at a point disposed to the other side of the said plane for retaining the lever in operative position. The head of the prop consists of a plate 1 having two vertically-depending legs 2, 3 which are disposed on opposite sides of the web 4 of the I-section girder constituting the body of the prop. A bolt 5 connecting the legs 2, 3 passes through a vertical slot 7 in the web 4. The arm 10 of the cranked lever is pivoted on a horizontal rod 8, Figs. 2 and 3, which is mounted between the opposite flanges of the girder, and the arm 11 extends upwardly and passes through a slot 14 in a plate 13 resting on the upper end of the girder. The leg 3 passes through a slot 12 in the plate 13, and a pin 15 locks the arm 11 to the plate 13. Normally, the longer leg 3 rests upon the arm 10 of the cranked lever. To release the prop, the nut 6 of the bolt 5 is released, the locking pin 15 removed, and the plate 13 raised until it is clear of the arm 11. In the modification shown in Fig. 6, the legs 2, 3 are provided with two bolts 5 passing through the slot in the web 4, and the prop is erected with the head in contact with the roof, but with the lower end of the leg 3 disposed above the arm 10. The bolts 5 are tightened sufficiently to yield as the roof yields, thereby allowing the head to move downwardly until the lower end of the leg 3 rests upon the arm 10. The Provisional Specification describes also the provision of two cranked levers for supporting the head of the prop.

Title: Automatic computer for use with mass spectrometers
Inventor: MORGAN WALTER AVERY
IPC: H01J49/02
Filed: 1963-06-05
Abstract: 979, 958. Electric analogue calculating. ESSO RESEARCH & ENGINEERING CO. June 5, 1963, No. 22353/63. Heading G4G A computer for determining the mass to charge ratio of particles analyzed in a mass spectrometer comprises means for obtaining a first current proportional to the ion accelerating voltage; means responsive to the first current for obtaining a second current inversely proportional to the ion accelerating voltage and including a solenoid, and a first Hall Effect Transducer in close proximity to the solenoid, the first current being fed through the transducer and the second current through the solenoid, and means responsive to the second current for obtaining a voltage proportional to the mass to charge ratio of ions brought to focus at the collector and including a second Hall Effect Transducer mounted between the pole faces of the mass spectrometer analyser magnet. The equation to be solved is M = k B<SP>2</SP>/V where M is the mass/ charge ratio, B is the magnetic field of the mass spectrometer, V is the accelerating voltage of the mass spectrometer, and k is a constant. A voltage proportional to V is tapped off resistance R2 and fed to amplifier A1 to produce an output current i1 proportional to V which is fed through a Hall generator T1 and feedback resistance R3. The magnetic field B1 of the Hall generator is produced by the output current i2 of amplifier A2, the input of which is the difference between a fixed voltage ER4 and the output of Hall generator T1. It is shown that i2 is then inversely proportional to i1 and to V. Hall generators T2 and T3 are situated in the magnetic field of the mass spectrometer and are used to multiply i2 by B successively to produce an output proportional to B<SP>2</SP>/V which is fed to a recorder 30 or a digital voltmeter. The circuit can alternatively be used to calculate k (YZ/X) by providing a voltage X across resistance R2 and feeding currents Y and Z to coils 32 and 33 providing the magnetic fields of Hall generators T2 andT3.

Title: Improved tape transport brake system
IPC: G11B15/43
Filed: 1964-06-03
Abstract: 1,032,385. Control of two motors. AMPEX CORPORATION. June 3, 1964 [July 12, 1963], No. 23052/64. Heading H2J. Tape 10 is adapted to travel in either direction between motor-driven reels 11, 12, a tapetension control circuit 14 and a tape-speed control circuit 16 being respectively connected to the pulling motor and holding-back motor. In response to the closure of any one of the switches 40, 42, 44, the tape is driven in the forward direction and memory circuit 56 is driven to a first state. Actuation of stop switch 36 energizes relay 30 to change contacts 18, 24, whereby the tape is decelerated under controlled tension. Circuit 72 indicates zero speed, so that circuit 74 causes memory circuit 56 to assume a second state, a circuit 76 then being energized to apply mechanical braking to the tape. If a rewind switch 52 is closed initially, coil 30 is energized and the tape is driven in the reverse direction. Actuation of stop switch 36 now de-energizes relay 30 to decelerate the tape. At zero speed, sensing circuit 72 operates switching circuit 74 to cause memory circuit 58 to assume a second state, thereby applying the mechanical brakes. The memory circuits 56, 58, each comprise a self-holding relay, the coils of which are connected in series with a first-transistor which forms part of the circuit 74. The circuit 72 comprises a potentiometer whose slider is coupled to the tape and engages a negative terminal at zero speed. When the tape-speed reaches zero a second transistor is forwardbiased so that the first transistor is biased-off to de-energize the relay-coil, Fig. 2 (not shown).
