Title: Re-processing of crosslinked polyolefin foam waste
Inventor: PARKINS JOHN CHRISTOPHER
IPC: C08J9/00
Filed: 1987-01-08
Abstract: Crosslinked polyolefin e.g. polyethylene foam waste can be successfully used with fresh uncrosslinked polyolefin e.g. polyethylene in the manufacture of a further polyolefin e.g. polyethylene product, after first subjecting the foam waste, in comminuted form, to controlled shear treatment, preferably in a continuous mixer extruder, at a temperature greater than 170 DEG C in order to reduce the degree of crosslinking and the viscosity of the waste material. The further product may be further crosslinked and/or foamed.

Title: Suction actuated lifting apparatus
Inventor: WALKER PETER DAVID
IPC: B66C1/02
Filed: 1987-01-22
Abstract: The lifting apparatus is of the type in which reduced pressure is continuously applied to the inside of an extensible tube (5) which is suspended at its upper end (4) and has a suction foot (6) at its lower end for holding an object to be supported and lifted. The suction foot incorporates a suction control device having an air chamber (10) communicating with the interior of a suction cup (7) of the suction foot (6). The air chamber (10) has a sleeve (100) defining an aperture for outside air to enter the chamber, and a plug (12) which is locatable into or out of the sleeve (100) for obstructing the aperture to a greater or lesser extent, to control the air inflow and hence the pressure within the chamber (10) to produce the suction effect at the suction foot (6) and a lifting force by causing tube (5) to be compressed. The plug (12) is carried on a shaft (11, 13) having a handle (25) which is pulled or pushed to move the plug (12) relative to the sleeve (100) for controlling the suction effect. The plug may be tapered and have a non-uniformly varying cross-section. <IMAGE>

Abstract: The apparatus comprises a bifurcated head 1 so that edge-plates 2 and 3 can be brought into contact with the periphery of a relatively rotating object 30. The points of contact B and C with objects of different diameter progress along location locus lines JL and KN which intersect at an apex A. Means 4,6,7 for responding to and detecting inaccuracies of the periphery is directed theretoward at an angle GAMMA with respect to a median line 1A passing through the apex A. In accordance with the invention, the detection means 4,6,7 is adjustable relative to the head 1 to accommodate test objects of different diameters, and this axis of adjustment 5A is so oriented that the point of contact G between the detection means and object will, between objects of different diameter, progress along a straight line parallel with the adjustment axis 5A intersecting the apex A. Proximity detection means (not shown) may be substituted, for the physical contact at point G. <IMAGE>

Patent GB-2241325-A (GB)
Title: Fiber optic gyroscope
Inventor: HUANG YUNG-YIEN
IPC: G01C19/72
Filed: 1990-11-13
Abstract: A fiber optic rotation sensing technique and a optical fiber gyro are provided which exhibit increased sensitivity to and linearity of rotation measurement by using a special dual-section, counter-wound fiber coil for measuring the Sagnac phase shift resulting from rotation of the coil. The optical fiber coil is formed of at least two separate interconnected coil sections 32, 34 each having a predefined number of turns of fiber. In the gyro arrangement, the separate sections are axially disposed adjacent to each other in such a way that the direction of winding of the turns in one of the coil sections is counter to the direction of winding of the turns in the other of the coil sections. The plurality of turns in each coil section is selected to be such that the sum of the effective lengths defined thereby is sufficient to realize the desired gyro modulation frequency. At the same time, the Sagnac phase shift for a given rotation rate is made proportional to the difference between the effective lengths of the coil sections and remains within a desired threshold level even if the overall effective length of the fiber coil is increased. <IMAGE>

Title: A method for producing skimmed milk powder
Inventor: LONERGAN KIERAN RICHARD
IPC: A23C1/04
Filed: 1991-06-10
Abstract: A method for producing skimmed milk powder from concentrated skimmed milk with a total solids content in the range of 34-42% TS comprises pasteurizing the concentrated skimmed milk at 34-42% TS in a direct steam injection pasteurizer and then raising the solids content of the pasteurized concentrated skimmed milk to in the range of 45-53% TS in a finisher. The concentrated skimmed milk is then pumped by a high pressure/homogenizer pump through a preheater into a main dryer from which the skimmed milk powder with a moisture content of approximately 6% by weight is produced. The temperature of the concentrated skimmed milk is raised up to 75 DEG C in the preheater. A secondary dryer reduces the moisture content of the skimmed milk powder to approximately 3.5% by weight. The method is also suitable for producing fat filled skimmed milk powder.
Patent GB-2264123-A (GB)
Title: Syphoning device
Inventor: DYER BRIAN
IPC: F04F10/00
Filed: 1991-11-22
Abstract: The syphoning system illustrated in the drawing is designed to be easily operated by one person. The first arrangement of the system requires one side nozzle of the T-shaped coupling 10 to be connected to a tap with the other side nozzle attached to the outlet hose. The syphoning process is initiated as follows. With the T-shaped coupling 10 held under water, a finger is placed over the unconnected nozzle of the coupling and the tap is turned on. After a short time the tap is turned off and the finger is used to sense whether or not water is being sucked into the unconnected nozzle. If not, the process is repeated until suction indicates that syphoning is taking place. The second arrangement of the system requires one side nozzle of the T-shaped coupling 10 to be blanked off using the cap 11 with the other side nozzle connected to the outlet hose. The operator connects the other end of the outlet hose to a tap and turns the tap on. Once bubbles cease to emerge from the open nozzle of the T-shaped coupling 10, the hose is fully charged and disconnecting the outlet end of the hose from its tap will result in syphoning taking place. The sucker ensures that the T-shaped coupling 10 is held under water. <IMAGE>

Filed: 1992-06-09
Abstract: A spot-type disc brake comprises a stationary brake carrier 19, a floating caliper 1 slidingly guided on the carrier, circumferentially spaced brake shoes 5, 7 fixed to brake pistons 13, 14, and a third brake shoe 6 fixed to the caliper such that its friction area point of gravity (36, Fig. 3) is circumferentially between those (35, 37) of the other two brake shoes 5, 7. In an alternative arrangement, there are two brake shoes on the opposite side of the disc which are more widely spaced circumferentially than the brake shoes 5, 7. Braking noises and brake rubbing are eliminated by these arrangements. The two-part caliper has apertures 2, 3, 4 for brake shoe replacement. In use, circumferential forces acting on the brake shoes 5, 7 are transmitted directly to the carrier and those acting on the brake shoe 6 are transmitted to the carrier via the caliper 1 and a guide pin 27. The shoes are fixed to the pistons and caliper by springs 50, 55 biassing projections 42 on the shoes into engagement with recesses 47 (43, Figs. 11-13). <IMAGE>

Title: Offset calibration of a DAC using a calibrated ADC
Inventor: SOOCH NAVDEEP SINGH
IPC: H03M1/10
Filed: 1992-08-21
Abstract: The output of a delta-sigma converter (44) is input to a one-bit DAC (48) and the analog output is filtered by an analog low pass filter section (50). During a calibration procedure, a calibrated analog-to-digital converter (ADC) (22) receives the analog output of the DAC with a "0" value being input through a multiplexer (58). The output of the ADC (22), which represents the inherent error in the delta-sigma converter (44) and the analog filter section (50), is stored in a register (62). in a second step of the calibration procedure, the contents of the register (62) are input through an interpolation circuit (40) for interpolation and storage in an offset register/latch circuit (56). The contents of the latch circuit (56) are summed with the output of the interpolation circuit (40) for input to the delta-sigma converter (44). By utilizing the interpolation circuit (40) in the calibration procedure, its gain can be compensated by the value stored in the register/latch (56). <IMAGE>
