Abstract: 467,322. Type-bar-making machines. INTERTYPE, Ltd. Dec. 22, 1936, No. 35167. Convention date, Oct. 21. [Class 100 (iii)] Moulds.-Means for selecting one of a number of moulds carried by the mould-disc comprise a hand-rotatable pinion, which is separate from the usual driving-pinion, and has such a number of teeth that one rotation thereof will rotate the disc through the distance between adjacent moulds, the engagement of the handdriven pinion with the mould-disc effecting the disengagement of the driving-pinion therefrom. Special coupling arrangements between the driving-pinion and its shaft are thereby rendered unnecessary. The additional pinion 17 is preferably mounted on the vice-frame of the machine, and can be rotated by means of a knob 19. The pinion-shaft is axially movable, and is held in the forward position, with the pinion out of gear with the mould-disc, by a spring-pressed lever 23. In this position, a hole in the pinion is engaged by a fixed pin on its bearing 20. The shaft 4 of the lever 23 has at its other end a lever 29, the upper end of which engages a groove in the hub of the driving-pinion 13. When the knob 19 is pushed back, the pinion 17 is moved into gear with the mould-disc and the driving-pinion is disengaged, so that the disc can be adjusted. When the vice-frame has been opened, the mould-disc can be rotated, to facilitate inspection and removal of the moulds, by drawing forwards the driving-pinion, so as to disengage it from its shaft, and rotating it by means of a knob. Specification 14582/90, [Class 100], is referred to.

Abstract: 1324181 Inductive signalling H A SCHAAD R L RANDOLPH and W J FOLEY 22 July 1970 [23 July 1969] 35407/70 Heading H4U In an inductive signalling system a signal from a microphone 12M, phonograph 12P, or radio 12R may be selected by a switch 11 and supplied via an amplifier 10, transformer 14 and an insulated conductor 27 to an earth pin 26 and via the secondary of the transformer at 23 to a further earth pin 23. The pins are spaced so that electrical conduction through the earth is negligible in comparison with displacement currents between the pins. This is stated to create in a large mass of the earth an electrostatic field with an associated magnetic induetion field in and above the earth. In order to extend the magnetic field further conductors such as 31, earthed at 30, may be connected to the conductor 27 by a switch 30D remotely controlled by coded signals from a unit 16. Alternatively, the signal may be detected by a pick-up coil, amplified and supplied to a further conductor earthed at each end. The impedance at the earthng point B may be reduced by the parallel connection of a horizontal rod embedded in the earth or one or more further vertical rods, which may be connected in circuit by remotely controlled switching. The receiver, Fig. 6 (not shown), includes a pick-up coil with a high permeability, flat laminated core feeding an amplifier in the form of an integrated circuit, a feedback circuit being included to eliminate noise due to power lines. Filters to eliminate high frequency and low frequency noise may be connected in the input to the amplifiers.
