Patent GB-2149241-A (GB)
Title: Control apparatus for hoisting drum elevator
Inventor: NOMURA MASAMI
IPC: B66B1/28
Filed: 1984-08-21
Abstract: A hoisting drum elevator having a cage 13 driven by an induction motor 1 which is energized by 3-phase power when ascending and by single-phase when descending. Comparator means detects whether the rotational speed of the motor rotated by the cage's own weight in the down-movement exceeds a predetermined value, and if so change-over control means (4a, 4b) connects single-phase electric power to the motor so that the motor is allowed to continuously rotate even if holding torque is generated by the single-phase excitation to ensure a positive downward running of the elevator. <IMAGE>

Title: Spectroscopy sample handling system
Inventor: SHIELDS J
IPC: G01N33/04
Filed: 1988-08-27
Abstract: System has an inlet (12) for a liquid sample, eg milk, connected to a sample cell (22) e.g. an i.r. cell and to a heat exchanger (24), a cylinder and piston (26, 28) connected downstream of the heat exchanger, and a one way valve (40) connected downstream of the sample cell. Retraction of the piston (26) draws sufficient fresh sample through the system to purge the previous sample.

Patent GB-2262009-A (GB)
Title: Beamforming communications
Inventor: WILKINSON ROBERT G
IPC: H01Q3/26
Filed: 1989-11-22
Abstract: HF aerials for ship-shore communications consist of spaced dipole arrays, 22. By appropriate adaptive phasing very high gain HF aerials are formed. On transmission a feedback signal is required from the receiver 24, otherwise similar algorithms are used to control the beamforming. A random phase algorithm (Fig 7) has been devised for the phases applied to the array aerials, operating in four tranches of 100 iteration steps with progressively reduced maximum phase variation. The initial step has a phase variation in the range +/-180 DEG . The algorithm has the advantage that there is a high probability that a relatively high gain beam will be immediately formed in the required direction and thus the system can quickly settle towards a direction where the signal is weak. When in the transmit mode the receiver returns a signal to the transmitter giving the step number of the random phases which gives the maximum received signal. A decision tree algorithm may be used in one direction of communication, (Fig 4). <IMAGE>
