Abstract: ABSTRACT OF THE DISCLOSURE      A method of making a fibre reinforced plastics structure having a plurality of layers, including a first layer which is fully consolidated with uniformly dispersed fibres and a second layer which is formed as an absorbent matrix.  The structure is formed from a first sheet of fibre reinforced thermoplastics material which will consolidate when cooled after subjection to pressure at a temperature above the melt temperature of the thermoplastics material of the first sheet and a second sheet of fibre reinforced thermoplastics material which will remain porous when cooled after subjection to pressure at a temperature above the melt temperature of the thermoplastics material of the second sheet comprising.  The method involves a first step of heating the first and second sheets to a temperature above that at which the thermoplastics materials of both of the sheets are caused to melt.  Then, the first and second sheets, whilst in surface contact, are subjected to pressure in a mould, whereby said first and second sheets bond together in conformity with the shape of the mould and form a laminated moulding having a fully consolidated first layer and a second layer at least a portion of which remains porous.

Abstract: Abstract of the Disclosure The wear life of a high-speed tool steel cutting bit is increased by (a) cleansing the bit by subjection to an ion beam; (b) while preventing the temperature of the cleansed bit from rising above 350°C, coating the cleansed bit by condensing sputtered atoms of titanium and boron thereonto, the condensation being carried out to provide a coating thickness of 2-6 microns.  An argon or krypton beam of ions is accelerated to 1300-1800 volts as a broad-beam ion source to sputter a titanium diboride target arranged as a cathode.  The sputtering is carried out for 5-10 minutes while the bit is heated to about 200°C and a soft vacuum of about 4-6 milli-torr is used during the process.

Title: Reverse phase-controlled dimmer
Inventor: MAIALE NICHOLAS F JR
IPC: G05F1/445
Filed: 1988-12-01
Granted: 1995-06-06
Abstract: Reverse phase-controlled dimming of an a.c.-powered load is accomplished by switching power to the load on and off during each half cycle.  In one embodiment of the present invention, power is switched on when line voltage is substantially equal to load voltage and off at a selected time later in the half cycle or at any time that the voltage across the switch exceeds a predetermined value. Preferably, switching is accomplished with a pair of field effect transistors.  The load preferably includes a capacitor from load hot to neutral.  The present circuit permits quiet dimming of incandescent lamp loads without the need for complex circuitry.  It is particularly well adapted for dimming low voltage lamps using a solid state transformer.

Title: Torque hold system and method
Inventor: TORRES CARLOS A
IPC: B25B23/145
Filed: 1989-07-05
Granted: 1993-06-29
Abstract: Abstract of the Disclosure Hydraulic tongs,  used to screw oilfield  tubulars together,  are equipped with torque control means which enable the tongs to rotate the tubulars and then gradually apply torque until a preselected torque value is reached, hold the torque at this value a desired period of time and then release the torque.  In one form of the invention, a tong control restricts the power of the tong motor to enable low torque rotation while limiting the maximum torque which can be produced by the tong motor.  A hydraulic cylinder placed in the tongs' restraining line is controlled to shorten,  hold or extend the line.  When the line is shortened, the tongs are pulled in a direction which increases the torque to a value above the maximum torque produced by the tong motor.   The  system  allows  heavy,  powerful  tongs  to  be  used  to accurately apply and hold a wide variety of selected torque values.
