Patent GB-798150-A (GB)
Title: Improvements in or relating to electric frequency dividing arrangements
IPC: H03B19/12
Filed: 1957-01-16
Abstract: 798,150. Frequency dividing circuits. STANDARD TELEPHONES & CABLES, Ltd. (Nippon Electric Co., Ltd.). Jan. 16, 1957, No. 1591/57. Class 40 (6). In an electric frequency dividing arrangement in which an oscillator B is synchronized at a frequency fo/n which is a sub-harmonic of the frequency fo of a second or driving oscillator A, a positive voltage E is applied to the cathode of the first oscillator B sufficient to prevent oscillation. When the driving oscillator A is working, a part of its output is tapped off and rectified to provide a positive bias which is applied to the grid of the first valve B to enable it to oscillate. Thus a monitor circuit D connected to the output of the first oscillator B will show an indication if either of the valves ceases to oscillate. The system may be extended if more dividing stages are used, and may be applied to a series of multivibrators.

Title: Improvements relating to sewage purification plant
Inventor: STRETTON HENRY JACKSON
IPC: C02F3/12
Filed: 1965-01-14
Abstract: A sewage purification plant comprises an aeration tank and a settlement tank and means for transferring the sewage being treated from the aeration tank to the settlement tank at a substantially constant rate other than by natural flow.  The transferring means may be an airlift, a rotating drum, an endless band, a centrifugal pump, chain buckets, screw conveyer, propeller pump or roller pump.  In Fig. 1, comminuted sewage from aeration tank A is lifted into transfer box 2 by air lift 1 from whence some flows over weir 3 into settlement tank B and the rest flows over the sides of tank 5 back into the aeration tank A, said sides being higher than the height of the weir 3 which height is adjustable.  If there is a sudden increase of flow from the air lift into the box 2, the relative shortness of weir 3 compared with <PICT:1106561/C1/1> <PICT:1106561/C1/2> the sides of the box 5 ensures that most of the overflow is over the side of the box, and there is only a small increase of flow over weir 3. The height of antisurge plate 9 may be adjustable, and a larger plate (81 in Fig. 4, not shown) may be placed similarly to scum barrier plate 8 but nearer to plate 9.  In Fig. 2 which employs a pump line 1 and a transfer box 2 similar to the transfer box of Fig. 1, the level in aeration tank A is kept substantially above a certain minimum by floating ball 14 which allows return flow from settling tank B at a certain level of sewage in tank A.

[Class 100 (i).] Sheet separators and carriers. - To increase the speed of sheet - separating mechanism, the separator is arranged to act on the front edge or side of the sheet which is at once displaced forwardly and laterally by the separator or by a sheetforwarding device, so that the separator can act on the edge or side of the next sheet before the uppermost sheet is withdrawn completely from the pile, and the withdrawal of.the second sheet is assisted by the one above it. A suction separator 14, Fig. 1, acting on the front side edge of the pile is carried by an oscillating arm 12 which is operated by a cam 9 on the main driving shaft 1. The separator 14 feeds the top sheet to a suction roller 8 which is rotated by gears 5, 6, 7 from the shaft 1, and is reciprocated laterally by means of a slotted arm 22 on an oscillating shaft 20 which is connected by bevel gears to a shaft 19 oscillated from a cam 16 by means of a lever 17.
