Title: Passageway lining cutter
IPC: F16L55/26
Filed: 1982-02-19
Abstract: A cutter device is used especially in an underground passageway which has been lined with a rigid resin lining, the cutter device cutting the lining where it covers lateral connections which must be re-opened. The device has a rotary cutting bit or liquid jet which is moved in an orbital fashion to enable the line of action of the cutter to be maintained parallel to the lateral connection. The cutter 18 is mounted on an axially adjustable front portion 20 of a passageway travelling unit. During cutting, a motor 36 rotates the cutter on a shaft 40, which, combined with the axial movement by a motor 24, provides the orbital movement. Cutter penetration movement is by motors 50 moving the cutter 18 about a shaft 46. Before cutting, the cutter axis is aligned with the connection axis by a motor 30 operating gears 32, 36 to rotate the front portion. Twin, independently and conjointly operated fluid cylinders may alternatively provide the orbital and penetration movements via a parallelogram linkage. <IMAGE>

Title: Method and apparatrus for use in temporal analysis of waveforms
Inventor: DAVIS GRAHAM ROY
IPC: A61B5/0488
Filed: 1983-07-07
Abstract: In single fibre electromyography it is useful to be able to measure intervals between waveforms (obtained from needle electrodes inserted into muscle fibres) reaching certain levels. A circuit is described, which is of general application, and which allows such intervals to be measured. Two comparators 22 and 23 which have adjustable reference levels receive an incoming waveform and, by means of polarity select circuits 27 and 28, provide outputs only when the reference levels are passed by waveform portions changing in selected respective directions. The time at which the comparator 22 is satisfied is available from a counter 33 but it is only passed to a computer interface 36 when the comparator 23 has also been satisfied. Enable circuits 29 and 30 prevent an output to the computer unless the comparators are satisfied within selectable time intervals. <IMAGE>

Title: A method of weighing-in milk tankers and a milk tanker for carrying out the method
Inventor: ANDREASEN CHRISTIAN MOLLER
IPC: B60P/
Filed: 1983-02-23
Abstract: A method of weighing-in milk in milk tankers for collecting milk from suppliers, in which the milk is pumped into a weighing tank (5) and during travel from one supplier to another is pumped fro m the weighing tank (5) into collection tanks (3, 4).
