Title: Improvements in or relating to electrical impulse generators
Inventor: WOODS-HILL WILLIAM
IPC: H03K5/07
Filed: 1952-02-13
Abstract: 703,038. Pulse generating circuits. BRITISH TABULATING MACHINE CO., Ltd. Feb. 13, 1952, No. 3858/52. Class 40 (6) The capacity coupling a source of oscillations to a detecting device is varied mechanically in a predetermined manner to generate a train of output pulses. An H.F. oscillator valve V1 feeds over a brush 6 a rotating metal disc 7 provided 'with teeth 8 and mounted on an insulating ring 9. The disc is rotated by a motor to bring the teeth in turn opposite a screened probe 11 feeding an anode-bend detector V2. The circuit 12, 13 is tuned to the oscillator frequency and capacitor 16 is arranged to have an impedance which is low at the oscillator frequency but high at the modulating frequency. As .the teeth pass the probe the capacity varies to alter the amplitude of the oscillations fed to the valve V2, the standing bias being such that the valve is driven into the fully conducting state when a tooth is opposite the probe. The valve V2 may be rendered ineffective by a negative bias supplied to the suppressor grid. Teeth may be omitted to give spaces in the pulse train, and a number of discs and detectors may be employed to provide a series of outputs. Alternatively a single disc and a number of probes and detectors may be employed when phase displacement only is required. A conducting pattern may be applied to a non-conducting disc and the discs may be attached by clips to a drum. The oscillations may be conveyed to the disc 7 inductively, the brush 6 being dispensed with.

[Also in Group XXIX] A container 1 mounted on a wheeled chassis hauled by a vehicle is filled with liquid manure by creating a partial vacuum within the container by an air pump 6, and drawing the manure through a pipe 33 which is dipped into a manure supply. When the container is filled the pump delivers air to a perforated rubber pipe 35, and air from the perforations passes through the manure and agitates it. This air may also accelerate the discharge from the container by setting up a pressure therein. The perforations, which are arranged along the bottom of the pipe, comprise slits which are opened by the air pressure. The pump, which is carried on and driven by the vehicle, has its suction inlet 10 and delivery outlet 12 connected by pipes 9 and 13 respectively to apertures 7b, 7c in a valve 7. In the container filling position a valve plug 18 is raised to close aperture 7b and suction. is created in the container via a pipe 20. Pump delivery is simultaneously connected through the valve and piping 15 to a silencer 16; a valve 36 prevents air flow from the pump to the pipe 35. When the container is full a float operated valve 23, 24 cuts off the pump suction. In order to agitate the material, in the container the valve 36 is opened, the plug 18 is lowered to close aperture 7c and to open aperture 7b to atmosphere. Container discharge is controlled by a valve 41 operated by a crank handle 46 through a linkage 42-45, and liquid manure is delivered downwardly on to a semi-circular spreader plate 47.
