Title: Electronic weighing machine proof against vibration - continuously remeasures deflection of grating or screen
IPC: G01G23/375
Filed: 1973-04-11
Abstract: Electronic weighing machines rely on a loaded pan moving a screen to uncover, or cover, a proportional number of opaque lines on a grating. The number of lines uncovered is repeatedly counted by a beam of light moved up and down perpendicular to the lines by an oscillating plane mirror. The mirror is itself moved by an electromagnet. A conventional photocell and electronic counter is used. Any electrical or mechanical transient in the system shows up by a slightly changing readout amd so can be allowed for. A screen 15 fixed to the base plate of the machine blocks out the lower part of the grating and is located so that its movement under vibration cancels the effects elsewhere in the optical system.

Title: End braking system for pneumatic cylinder movement - hydraulic cylinder connects to reservoir through a cut-off valve
IPC: F16F9/06
Filed: 1973-09-13
Abstract: The brake and stop for parts which have a rectilinear motion produced by a pneumatic cylinder gives precise control at low cost. The button (3) on the moving part (1) strikes the head (4) of the braking cylinder (5) and pushes back the piston (6). Hydraulic fluid (12) passes through a restrictor (14) on pipe (8), thus slowing the part. A photoelectric cell (15) operates just before the stop position and a valve (13) cuts off oil flow into the reservoir (9) and stops the part (1). On retracting, the valve (13) opens and the air space above the oil in the reservoir is pressurised. Oil is forced into the cylinder (5) and the brake is ready again.

Title: Seismic exploration by groups of constant frequency wave trains - involves variably weighting detected signals before recombination
IPC: G01V1/28
Filed: 1974-01-10
Abstract: A group of wave trains of constant frequency is emitted in the direction of the ground and the resulting signals are detected at a point spatially separated from the point of emission and are combined. A weighting is applied, variable with time, to the amplitude of the signals detected before this combination. This takes account of the variations in the attenuation offered by the ground as a function of frequency. The median frequencies of the wave trains may form an arithmetic progression or a geometrical progression. The emitted wave trains, may be amplitude modulated. Preferably a narrow band filter is used for the detected signal.

Title: Transmission for underground drilling motor - with axially displaceable coupling for locking the motor stator and rotor to release a jammed drill bit
IPC: E21B17/046
Filed: 1974-01-22
Abstract: Device for permitting the rotor of an underground drilling motor to be locked relatively to the stator, has (i) the shaft of the underground motor provided with a sliding sleeve fixed to the drill bit and normally retained by suitable devices in a first axial posn. with respect to the motor shaft, which permits the axial force and normal rotational couple of the motor to be transmitted to the drill bit, and (i) (ii) devices for retaining the sleeve in this first posn, such that if the drill bit jams, the sleeve can take up a second axial posn. with respect to the shaft so that it and the drill bit is directly fixed to the motor body. Thus when the drill bit has jammed on the bottom of the borehole, it becomes possible to apply a very high torque above that which can be supplied from the motor, via the drilling pipe string and the motor body, so as to release the drill bit.
