Title: Method and apparatus for wire drawing
Inventor: NEWBERRY JOHN
IPC: B21C1/12
Filed: 1990-03-01
Abstract: The apparatus comprises a plurality of dies 2 in series and a drawing block 4 for drawing the wire through each die. Each drawing block is driven by independently adjustable means which derive their motive power from a common source which is itself adjustable and which also provides power to a take-off reel 14, also independently adjustable. Each of the drawing blocks has a plain cylindrical surface in driving engagement with the wire. The torque exerted by each drawing block is adjusted in sequence so that the force required to draw the wire through the die and around the drawing block and subsequent dies and drawing blocks is a minimum. Once each of the drawing blocks and the take-off reel is set in this manner the machine can be run up to speed by adjusting power from the common source. The apparatus enables wire of high surface quality to be manufactured by avoiding slip between the wire and drawing block. <IMAGE>

Title: Improvements relating to spreading machines
Inventor: LUPTON WILLIAM GEORGE
IPC: A01C3/06
Filed: 1990-03-22
Abstract: The invention provides a spreading machine comprising a hopper 10 with sloping sides and an auger 21 in the base of the hopper.

Title: Inspection aperture plug assembly
Inventor: HIRST ROY TALBOT
IPC: F01D21/00
Filed: 1990-05-17
Abstract: An inspection aperture plug assembly (19) suitable for use in an inspection aperture (16) in the casing (10) of a gas turbine engine comprises a body portion (18) which locates in the aperture (16) and a removable plug portion (23) which locates in an aperture (22) extending through the body portion (18) for normally sealing an aperture (15) in a pressure vessel (11).

Title: Measuring calliper
Inventor: BEST ROBERT EDWARD
IPC: G01B3/38
Filed: 1992-09-18
Abstract: A calliper, useful for measuring how much fat can be pinched beneath the skin, comprises jaws (4, 6) mounted for relative pivotal movement. The movement is amplified by a gear train (22, 24, 26, 28 and 30). The final gear wheel drives a toothed wheel (32) the movement of which is sensed by an opto sensor (34). Pulses from the opto sensor (34) are counted by an up/down counter. A direction sensor provides a signal indicative of the change of jaw direction to the up/down counter. A digital readout indicates the spacing between the jaws for indicating the spacing between measuring surfaces of the jaws. In contrast to conventional callipers, which are used only to transfer a dimension from an object to be measured to a measuring device, the callipers disclosed give a direct reading of the spacing between the measuring surfaces. The surface (16) of jaw (4) may contain a pressure sensitive switch. <IMAGE>

Title: Knocking detection system and method for an internal combustion engine
Inventor: SOGAWA YOSHIYUKI
IPC: F02P5/152
Filed: 1992-01-30
Abstract: A knocking detecting system comprises a microcomputer with an A/D converter 4 which receives a frequency signal processed in accordance with the vibration signal of a knock sensor 1. The microcomputer carries out the A/D conversion steps (S1 - S4, Fig 2, not shown) of continuously sampling digital values, the steps (S5 - S9) of integrating the differences between the digital values and a background level over a detecting period, and the steps (S10 - S12) of comparing the integrated value with a judgement level, thereby to judge the presence of knocking and to evaluate a knocking level. The background level is determined by the microcomputer by averaging digital values from the A/D converter, calculating a weighted average of the averaged digital value and multiplying the weighted average with a coefficient. Thus, the knocking is detected, and the background level is calculated at high precision. <IMAGE>
