Title: Method for preserving large sections of biological tissue with polymers
IPC: A01N1/00
Filed: 1980-08-13
Abstract: Method of preserving large sections of biological tissue with curable polymers e.g. acrylic resins, allyl diglycol carbonate, unsaturated polyester resins, epoxy resins, polyurethanes or silicone rubber, by impregnating these large sections with the polymer and pressing the impregnated large sections (b) between flat plates (a), preferably toughened glass plates. These plates are additionally separated near their edges by an elastic material (d), thus providing a flat cell, wherein both cut surfaces of the impregnated large section are abutting against the inner surfaces of the two plates of the flat cell. Thereafter, the cell is filled up with uncured polymer (c) and (g). Air bubbles (h) are allowed to rise, subsequently the polymer is cured whereby the plates are moving toward each other due to the polymers shrinkage during curing. Afterwards the plates are removed. The resulting plastinated sheet is a permanently preserved large section of biological tissue, whose tissue water is completely replaced by a cured polymer. The surface is even, the thickness uniform and about that one of the large section before treatment. Many variations of the technique are possible. For example the glass-plates of the flat cells can be covered with separating foils or casting can be implemented with a large section which is already impregnated with cured polymer. <IMAGE>

Title: Grinding and deburring turbine blades
IPC: B24B5/36
Filed: 1981-03-31
Abstract: A multi-stage compressor or turbine rotor (19) has grinding operations carried out on the successive blades along the workpiece at different radii and at different angles. It is mounted between centres on a slideway (12). A motor driven grinding wheel (43) is mounted in a grinding head (20) mounted on a slide (21) to traverse the grinding wheel towards and away from the workpiece. The grinding wheel is mounted on a carrier (27) pivoting on the slide for rotational adjustment about an axis (29) extending tangentially to the periphery of the grinding wheel (43) which engages the workpiece for adjustment of the angle of cut of the grinding wheel. Since the grinding wheel turns about the axis when its angle is adjusted, the position of the angle of cut is not otherwise varied by the angular adjustment of the grinding wheel. A microprocessor control mechanism (65, 66, 67, 68, 70, 71, 72) is provided for enabling the grinding wheel to be accurately pre-set to a number of pre-determined angles to suit the workpiece to be ground. The control acts via a stepped bar, a spider on an angularly indexed rod contacting the bar, and a lead- screw controlled thereby. The wheel is periodically dressed and readjusted to the tangential position. A de-burring bush pivots about a vertical post to act on the blades after grinding. <IMAGE>

Title: Vehicle cab tilting arrangement
Inventor: PEARCE PETER
IPC: B62D33/067
Filed: 1981-08-07
Abstract: The tilting arrangement includes a hydraulic ram comprising a piston 2 displaceable in a hydraulic cylinder 1 to effect tilting. A by- pass 6, 8, 8a connected between hydraulic pressure spaces 4, 5 on either piston side is controlled by a fluid pressure operated valve to which pressure fluid is also supplied via a line 28 for the cylinder space 4 on the lifting piston side. The valve closes said by-pass for ram extension, said valve comprising a resiliently biased spool 11 displaceable in a transverse valve chamber 10, to control the by-pass. To ensure free movement of the piston (and hence the cab) over prolonged periods of use, resilient bias 19 on the spool 11 normally maintains the latter in a travel position connecting the cylinder spaces 4, 5 via said by-pass. By-pass valve ports 8a, 12 are closely adjacent and the valve spool provides a direct, connection between the ports when in its travel position. The valve spool end faces present equal effective surface ares in said valve chamber, ensuring that the spool remains pressure balanced when in its travel position with the resilient bias continually effective. <IMAGE>

Patent GB-2123950-A (GB)
Title: Intruder detection system
Inventor: SOUTHCOTT PETER
IPC: G08B13/184
Filed: 1982-07-15
Abstract: An intruder detection system uses one or more sheets of obliquely reflective foil on the ground in the region to be protected. Such foil consists of an aluminium foil whose surface is covered with a dense columnar structure of inclined spinules. Light incident on the foil aligned with the spinules is reflected very little if at all, while light at right angles to the length of the spinules is reflected. As used in the present system light from a source (6) is directed along the normal to the pseudo-surfaces (indicated at 3) defined by the spinules, which light is reflected back to the viewer. If an intruder passes the distortion to the foil distorts some at least of the pseudo-surfaces, which reduces the amount of light reflected back. This reduction is readily detectable. The light source can be an infra-red source, in which case detection uses an infra-red detector-alarm arrangement. <IMAGE>
