Abstract: 1,129,046. Weighing apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 25, 1967 [Aug. 4, 1966], No.34933/66. Heading G1W. [Also in Division G3] In an automatic feed weigher comprising a weigh pan 1 which is fed with material from a hopper 27 and which is suspended from a pistion 3 movable within a tapered cylinder 4 to provide a variable leak between the piston and cylinder, the cylinder 4 has an inlet port 7 for admitting gas under pressure which opposes the weight of the pan and its contents, and a pneumatically operated switch 14 is arranged to be operated by the gas pressure within the cylinder when such pressure is at least of a predetermined value, the switch when operated being arranged to interrupt supply of material to the pan. The pan 1 which is fed with material from the hopper 27 by a vibratory conveyer 26 is arranged to be tilted by a ram actuated pivoted lever 35 when the pan has received a predetermined weight of material so as to tip the material from the pan. The vibratory conveyer 26, pneumatically operated switch 14 and ram 38 are arranged in such a way that batches of material are weighed successively at regular time intervals, the feed to the pan being cut-off when a predetermined load is on the pan and before such load is discharged by tilting the pan. The switch 14 is so arranged in an electric circuit comprising transistors, relays, cam actuated switches and an electric motor driving the cams that any departure from a required feedrate of material from the hopper during one weighing operation is corrected for the following weighing operation by automatic adjustment of the operation of the conveyer 26. The pneumatically operated switch 14 comprises a pair of contacts 22, 23 arranged at different levels in a tube 16 up which mercury 15 rises by an amount proportional to the pressure below the piston 3 in the cylinder 4, the mercury on reaching contact 23 causing a current to flow via a contact 46 thereby to cause the vibratory conveyer 26 to effect a dribble feed to the pan, the feed being completely stopped when the mercury 15 short circuits contacts 22, 46. A counter may be arranged to count the batches weighed by the apparatus.

Title: Improvements relating to electron discharge amplifying apparatus
IPC: H03F3/28
Filed: 1928-11-28
Abstract: 325,833. Carpenter, R. E. H. Nov. 28, 1928. Thermionic amplifiers. - Use is made of the phase opposition in voltage between the input and output circuits of a thermionic valve to secure " push-pull " amplification, the output voltages being symmetric about a neutral point which is a symmetric with respect to the input. As shown in Fig. 2, the voltage at the point 11, derived from the anode of valve A, is in opposite phase to that at the point 12 which is taken from the the anode of valve B. The point 13 is at the potential of the input terminal 2. To maintain the two outputs at equal amplitude, the grid voltage of the valve B is taken from an intermediate point 10 on the anode resistance 3 so as to compensate for the amplification factor of the valve A. For fined adjustment the grid input of valve B may be taken from a tapping 8a, on the leak resistance. To minimize " hum when the valves are energized from the mains, a symmetrical cross-connection from a tapping 37, Fig. 5, on the anode resistance 9 may be taken to the grid of the valve A. In a modified arrangement, Fig. 6, the necessary fractional grid voltage is fed to the valve B from a tapping 41 on a high resistance 40 shunted across the anodes of valves A, B. A symmetrical cross-connection (not shown) may also be taken from the opposite side of the centre point m to the grid of the valve A to eliminate " hum." In order to ensure a uniform overall amplification, a circuit comprising a resistance 43, Fig. 7, in series with a tuned loop circuit 44, 45 may be inserted across the anodes of an intermediate pair of valves G, H. This circuit is tuned so as to shunt the lower frequencies more readily than those higher frequencies normally attenuated by capacity leakage. The final output currents may feed separate loud-speakers, or may flow through branch circuits comprising different impedances. Specification 314,605 is referred to.

Patent GB-360376-A (GB)
Abstract: 360,376. Transfer mechanism. PETTERS, Ltd. and PETTER, G. B., Westland Works, Yeovil, Somerset. Aug. 1, 1930, Nos. 23257 and 27805. [Class 106 (i).] Transfer mechanism for use with multiple-bank key-set-and-operated calculating machines comprises a cam rotated by means in one denomination, a transfer element actuated by the cam and associated with a pinion in the next higher denomination and means for moving the transfer element out of the path of its associated pinion for a predetermined period before the instant at which transfer is due to take place. The mechanism as shown in Fig. 2, is adapted for a machine having only five keys in each bank, digits of value greater than 5 being registered by depression of two keys in the same bank successively. The cam 6 secured to the lowerorder pinion 1 during the clockwise rotation of that pinion depresses a transfer lever 7 against the action of a spring 12. An arm 10 of the transfer lever 7 moves a lever 11 anticlockwise by a pin-andslot connection, a pawl 13, pivoted to the lever 11 and having a transfer tooth 14, slipping over the higher-order pinion 2 under the control of a spring 15. When the transfer lever 7 slips over the end of the cam 6 the spring 12 causes the actuation of the higher numeral wheel. To prevent overthrow the tooth 14 is lifted out of engagement with the pinion 2 for a predetermined time before transfer by a projection 16 of the cam 6. Since the largest single actuation which can be given to the pinion 1 comprises 5 units the cam 6 is shaped so as not to engage the transfer lever 7 (and so interfere with the completion of a transfer action) until the associated numeral wheel has passed the reading " 4." In the case of banks each containing nine keys the arrangement shown in Fig. 5 is adopted. The cam 18 is secured to the pinion by a yieldable connection 20. A projection 24 on the cam engages a lever 22 and holds the cam immediately after a transfer has taken place until the lever 22 is tripped by a projection 27 on the transfer lever 7 as the latter completes its stroke. In a further modification, Fig. 6, the transfer tooth 32 is secured to a lever 29 engaging by a pin-and-slot connection with the transfer lever 7 and having a slot bearing 30 on the spindle 3. The lever 29 is controlled by a spring 31 and has a projection 33 which is engaged by the overthrow-preventing member 16. In further modifications, the pawl carrying the transfer tooth is pivoted directly to the transfer lever. Also an additional lever, loosely pivoted on the same axis as the transfer lever, may be interposed between the overthrow-preventing member and the transfer tooth carrying pawl. Specifications 360,375 and 360,377 are referred to.
