Abstract: 1,013,412. Stereophonic systems; sliding bias amplifiers. TESLA NARODNI PODNIK. June 29, 1964 [June 29, 1963 (2)], No. 26790/64. Headings H3T, H4J and H4R. An asymmetrical push-pull amplifier stage for stereophonic signals comprises, Fig. 3, a pair of similar amplifying elements V 1  and V 2  connected in series across a power supply B 1 , B 2 . The stereophonic channel signals are applied, one direct to element V 1  and the other in reverse polarity to V 2 , it is shown that between tapping a and the centre tap S of the transformer connected in series between the amplifying elements appears one channel signal while the other channel signal appears between the tap b and the centre point S. A sum signal may be obtained between the centre tap S and the centre tap of the power supply O. Negative feedback may be taken from points Zp and Zl and the valves V 1  and V 2  may be replaced by common emitter transistor amplifiers, Fig. 4 (not shown). The outputs from additional windings on the transformer Tp may be rectified and fed back to vary the bias on the amplifying elements so that while no signal is passing they are biased in class B but as soon as a signal is present the bias is changed to class A. The bias may be applied direct to the output amplifier elements. Fig. 5 (not shown) or to previous amplifier stages of c coupled to the output elements as shown for the driver stage Q 4 , Fig. 6.

Title: Improvements in or relating to cutting machines
IPC: B23Q7/00
Filed: 1927-10-18
Abstract: 279,451. Sussman, M. H. Oct. 19, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Circular-saw machines.-In a machine for cutting or severing travelling work such as bars or pipes, the bar stock travelling to the right passes between clamping jaws 57, 58 on a carriage running on frame bars 5, which jaws at the beginning of a cut are closed by cams 62 operated by the descent of a tool carriage 53, which carries a saw 54 and its driving motor and is hung from a bar 34 supported between two plates 32, 33 which are intermittently rotated from the main driving motor 7 through an electrically-operated one-revolution clutch 16. Thus as the saw carriage 53 begins to slide downwards on guides 66 it also starts moving to the right with the work and continues so to move, until the jaws 57, 58 are opened by the completion of the rotation of the plates 32, 33. The tool carriage is then returned to its left hand position by the lower run of a chain 48, which is engaged by a spring catch 79 on the carriage as the latter is returned to its upper position. At the end of this return travel the carriage is disengaged from the chain by a cam 86, checked by spring buffers 88, and held by a catch 89, which is released by the downward movement of the carriage at the beginning of another cutting operation. The piece cut off is carried away by a chain 98, driven faster than the chain 48, and is delivered to a receiver 111. The moment of actuation of the clutch 16, and therefore the length cut off, is electrically controlled by means of a gauge switch 121 adjustable along a bar 113. The end of the severed piece moving along with the chain 98 strikes a verticallyhanging latch 122 and actuates a spring-mounted slider 125 to close the switch against a spring 126, which opens it again as soon as the latch slips under the lower end of the slider. A solenoid 135 is excited on the closing of this switch 121 and closes a switch 138 which brings the clutch 16 into operation. At the same time the solenoid 135 closes a switch 140 which keeps the solenoid in excitation until a switch 142 is opened by cam action from the clutch 16. Separate hand-operated switches such as 144 may be arranged to allow extra cuts to be made as desired. The machine is constructed without a bed plate, the end frames being connected by pairs of frame bars 5, 6.
