Abstract: 375,324. Typewriters. ROYAL TYPEWRITER CO., Inc., 2, Park Avenue, New York, U.S.A.-(Assignees of Davidge, E. A. ; 53, Dartmouth Road, Hendon, London.) March 21, 1931, No. 8757. Convention date, June 7, 1930. [Class 100 (iv).] Platen rotation for condensed billing.-In arrangements comprising a hand-lever provided with a pawl for turning the platen or feed-member backwards and forwards, the forward feed being greater than the backward, spring means is provided for holding the pawl in engaged or disengaged position, and the stop-means for the hand-lever consist of a circumferentially adjustable stop-pin and a radially movable stop-arm co-operating.with a stationary stop, the stop-pin being retractable to permit of feeds of more than one revolution. In the apparatus shown in Figs, 1, 3 and 6, a ratchet wheel 16 on the platen shaft B cooperates with a pawl 19 pivoted on a handlever 17 and formed with a recess 21 which engages a pin 23 on a bell crank 24 pivoted on the hand-lever. The pawl and bell crank are connected by an over-centre spring 25. The pin 23 co-operates with an adjustable stop-pin 12, and a stop 29 formed on a loose radial arm 27 which abuts on a pin 26 on a stationary disc 7. The stop-pin is mounted in a sleeve 11 on a loose arm 10 and normally projects through one of a series of holes 9 in the disc. The stop-pin can be retracted by means of a knob 13 passing through a slot 14 having a recess for holding the stop-pin in the position shown in Fig. 3. The pin 23 co-operates also with a fixed pin 31. Initially the pin 23 abuts on the stop 29 and rests in the front of the recess 21, the pawl being disengaged. When the handlever is advanced, the pawl remains disengaged until the pin 23 engages the pin 31 and is moved to the rear of the recess, the pawl being thereby positively coupled to the ratchet wheel. Further movement of the hand-lever turns the platen backwards to feed backwards the recordsheet and invoice, feed continuing until the pin 23 engages the stop-pin 12. After substitution of another invoice the hand-lever is returned to feed forwards the record-sheet and invoice. During return of the hand-lever, the pin 23 passes idly under the pin 31 and the pawl remains coupled to the ratchet wheel until the pin 23 engages the stop 29, the forward feed of the record-sheet exceeding the backward feed by one line-space. If it is required to turn the platen through more than one revolution, the stop-pin 12 is retracted to the position shown in Fig. 3. During advance of the handlever, the pin 23 passes the stop-pin and carries forward the arm 27, the movement continuing until the arm engages the stop-pin. During return of the hand-lever, the pin returns the arm to initial position.

[Glass 108 (iii)] [Also in Group XXIV] A resilient mounting for a machine &c. comprises two or more resilient supporting systems and adjusting means whereby one or more of the systems may be partially or wholly disconnected so that for slow ranges of speed of the machine the natural frequency of the mounted part may be arranged to lie above these speed ranges and for high ranges of speed of the machine the natural frequency of the mounted part may be lowered to lie below these speed ranges by disconnecting wholly or partially one or more of the supporting systems. As shown, a motor 1 drives a testing machine 3 at various speeds and is mounted on a base 4 supported on a cylindrical rubber mounting 6 carried on a pedestal 9 operable by a lifting device 10. Supporting blocks 13 of rubber are arranged around the base 4 and a further elastic system 15 may be connected to the base. When the frequency of the exciting forces lies, say, above 300 r.p.m., the mounting 6 only is operative and due to its arrangement and dimensions causes the natural frequency to lie below the exciting frequency. When the testing machine rotates at a lower speed, the exciting frequency is lower and the base is lowered until it is partly or wholly supported on the elastic mounting system 13 so that the natural frequency lies above the excitation frequency.

Abstract: 794,200. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd..March 28, 1956 [March 30, 1955], No. 9216/55. Class 39(1). [Also in Group XL(c)] In an image pick-up tube subjected to interlaced scanning and particularly in a fieldsequential colour camera tube to prevent colour " hang-over," means are provided to cause the beam scanning non-consecutive lines to scan the interlaced lines during line retrace intervals, the beam intensity being increased during line retrace and the beam velocity simultaneously increased to maintain the beam in focus whilst discharging the interlaced lines towards or below the normal cathode potential. The C.P.S. pick-up tube 1 has a photo-sensitive mosaic 5. and normal scanning and focusing coils 9, 10, 11. A potentiometer 12 has tapping points connected to the gun electrodes 2, 3, 4 and to the wall electrodes 8, 6, its end being connected to the join between resistors 14, 15 applied between electrode 3 and ground. In shunt with resistor 15 are a valve 16 and a diode 18, each connected through a source 17 to ground. A pulse generator 24 yields negative pulses during line retraces for several purposes (a) to feed into scanning circuit 23 and displace the beam backwards, (b) to feed into amplifier 25 and cut-off during line retrace, and (c) to derive positive pulses from polarity reversing amplifier 27. These positive pulses may be cleaned up by catch diodes or by causing the amplifier 27 to function as a limiting amplifier and they are fed to control electrode 3 to intensify the beam from cathode 2. These pulses are also fed via capacitor 21 to the control electrode of valve 16 which becomes conducting and reduces the potential between resistors 14, 15 bringing the cathode 2 a few volts negative of its usual value. The diode 18 also becomes conducting at the appropriate potential and prevents the potential of cathode 2 falling below that value. The potentials of anodes 4 and 8 are also lowered and the beam velocity is increased sufficiently during line retrace to maintain the beam in focus whilst keeping the secondary emission at the target less than unity. The nodal displacement of the beam is arranged to be small or an integral multiple of the distance between nodes. This may be achieved by polarising wall anode 8 from a separate source. The consequential charging of the interlaced lines to a potential more negative than normal cathode potential may be corrected by bias lighting or by using a leaky dielectric for the target and applying a positive potential to the signal plate. Displacement backwards of the beam during line retrace may be achieved by auxiliary frame scanning coils or deflecting plates. Instead of lowering the cathode potential during line retrace, that of the signal plate may be raised by an equivalent amount. The beam may be cut-off during line suppression intervals to provide a datum level for D.C. restoration purposes.
