Title: Borehole direction measuring device - having single-degree-of-freedom gyro and gravity sensors to give inclination and azimuth
IPC: E21B47/022
Filed: 1977-12-14
Abstract: A bore-hole direction measuring instrument has a gyro rotor mounted in a pair of gimbals to form a single degree of freedom gyro, a pick-up and torquer sensing and cancelling relative movement between the gimbals. A resolver measures the rotation of the torquer relative to the instrument casing and a gravity sensor unit measures gravity components along the axes. To survey a borehole, the pick-up and torquer continually operate to eliminate the relative rotation of the two gimbals and at a series of stations gravity components are sensed in three orthogonal directions relative to the outer gimbal. From these measurements the borehole inclination and azimuth are calculated for each station. The use of a single-degree of freedom gyro simplifies instrument design and makes gimbal bearing friction less critical.

Title: Inhibition of dust from flour by oil coating - using metering device to proportion atomised oil onto flour pref. in an amt. of 1.5 wt. per cent
IPC: A23L19/10
Filed: 1978-05-12
Abstract: Flour, esp. tapioca flour, is rendered dust free by spraying it with atomised plant or animal oil in an atomised condition and in the proportion of ca. 1.5% by wt., this being the best proportion to prevent dust without adversely affecting the fluid properties of the powder. The appts. comprises a feeder/seive for the flour, a metering device for the oil, a mixing arrangement for the flour with the atomised oil and a conveyor for removing the mixt. Used esp. in inhibiting dust pollution of the atmosphere in transferring the flour from sea ships into inland barges or coasters; pref. the installation is built into an intermediate ship between the sea ship and the elevator ship or built into the elevator ship itself. Fluid properties of the flour are not affected and since the oil is applied to the flour in its finest form, there is no subsequent breakdown of the flour particles to reduce the effectiveness of the treatment.

Title: Loading mechanism for ships hold or silo - limits dust prodn during loading of loose material. using hydraulic pump and manually-adjusted regulator
IPC: B65G11/20
Filed: 1987-03-06
Abstract: The material passes from a chute (1) into a tube (2) which has a viewing window (3). At the bottom of the tubes are deflection plates (6) mounted on a central hub (7). The plates impart an angled motion to the material that when it reaches the lower section (9) of the device it transfers energy to the blade (10) of a helical screw. As the screw turns it delivers the loose material via the output nozzle (24). The screw, which is mounted on a central shaft, drives a hydraulic pump (8). The pitch of the screw is not uniform but reduces as it passes down the column. The output of the pump is connected via a reducer (18) to a regulating device (19). The operator can adjust the regulator to reduce the material flow significantly e.g. down to one metre per second. Alternatively the system can incorporate an electric motor and control system in place of the hydraulic system.
