Patent GB-2081340-A (GB)
Title: Deformable mine prop
IPC: E21D15/02
Filed: 1981-07-13
Abstract: A prop made from an elongate timber element. The cross-sectional area of the element is reduced in at least one region e.g. by tapering the element, forming circumferential grooves in it, or boring holes axially or transversely into or through the element. The region of reduced cross- section is reinforced by means of bands or a sleeve which extends circumferentially around at least part of the region. The reduced cross-sectional area promotes deformation of the prop and the reinforcement controls the rate of deformation. <IMAGE>

Title: AC motor control
IPC: H02P1/42
Filed: 1981-08-03
Abstract: An energy-saving control for an A.C. motor operates to feed a high average value of voltage to the motor during a starting period of predetermined duration and after a predetermined time to automatically switch the voltage supplied the motor to a lower average voltage of substantially fixed value. This lower value of average voltage is determined without feedback to the control circuit. The control circuit is simple, reliable and inexpensive. It may be designed for use with single phase or multiple phase motors and for motors of various different power ratings.

IPC: B65H23/24
Filed: 1983-08-15
Abstract: Air bars 12 extending lengthwise parallel to one another are mounted on the front of a plenum chamber 10 with their front walls 28 lying substantially on an arc around which a moving web W is guided. Each air bar 12 has a pair of elongate Coanda nozzle outlets 29, extending along the opposite longitudinal edges of its front wall 28, through which pressurised air from the plenum chamber 10 emerges as streams that converge across the front wall 28 and which support the web W without contact between the web W and the front wall 28.

Abstract: An adjusting device consists essentially of two angle pieces (3, 5) which fit into one another with a spacing between them, each having a leg (11, 16) extending in parallel with a stationary support (1). The horizontal leg (11) of the lower angle piece (3) is connected to the support (1) via a hinged joint, while a further hinged joint (4) connects vertical legs (12, 13) of both angle pieces (3, 5) to one another. On the horizontal leg (16) of the upper angle piece (5), the object to be adjusted is disposed either directly or in the receptacle (15) of an adjustable stage (9) mounted on the leg (16), for moving the object in the direction of the Z coordinate. The receptacle (15) is so designed that its centreline is in agreement with that of the object to be adjusted. Moreover, the vertical legs (12, 13) are dimensioned to have such lengths that the swivel axis of their hinged joint (4) lies horizontally in one plane next to the centre line of the object receptacle. By swivelling both angle pieces (3, 5) about the axis of the lower hinged joint, the object is displaced in the direction of the X coordinate, and by swivelling the upper angle piece (5) about the axis of its hinged joint (4), the object is displaced in the direction of the Y coordinate. <IMAGE>

Title: Ignition regulation in an internal combustion engine
Inventor: BERCHTOLD MAX
IPC: F02P19/02
Filed: 1985-01-24
Abstract: The ignition timing is controlled by increasing the temperature of an electrically heatable ignition device 20 in the region of the required instant of ignition. A constant current source 30 supplies current to the device 20, the actual temperature of which is compared with a reference temperature in a comparator 28. The comparator is connected to a control 31 which also receives signals relating to engine operating parameters such as engine speed, accelerator pedal position, fuel/air ratio, engine temperature, &c. The control 31 switches on a transistor 22 to allow an increased current flow to the ignition device in the region of the calculated ignition instant.
