Abstract: A resistance element of elastic material has at least an interconnected portion coated with a nonfriable electrically conductive material forming an electrical path that changes its resistance as a function of the state of tension or compression of the resistance element. A conductive material is prepared from particulate electrical conductive material, an elastic binder and a solvent. Pretreatment of an elastic material of elastomer foam prior to application of conductive material produces a useful resistance element.

Abstract: An improved dental endosteal implant (2) is disclosed. The implant comprises a base (4) and a core (6). The base is comprised of a bio-compatible material and has first and second ends (8, 10) axially spaced along the longitudinal axis of the base and side walls (12) which include serrations comprising alternating oblique and substantially planar surfaces (16, 14), the substantially planar surfaces being substantially perpendicular to both the longtidunal axis and the direction of the intended occlusal load, and said oblique surfaces being disposed at an angle to the longitudinal axis of said base. The surface area of the planar surfaces nearest said second end is greater than the surface area of the planar surfaces nearest the first end, the first end (8) being the outermost end upon implantation and the second end (10) being the implanted end. The core (6) is configured so as to permit cooperative engagement with at least one prosthetic crown.

Abstract: The apparatus is intended to discriminate between genuine and undesired documents such as bank notes. The note is illuminated at selected sites and the spectral content of the reflected light is analysed by a photocell. All the test sites are illuminated by a light source within a transparent block of preferably synthetic resin, which distributes the light to opening adjacent the sites. The photocells are mounted in a recess in the block.

Abstract: An improved biodegradable prosthetic implant is disclosed for use in the healing of bone voids. The implant comprises a body member consisting essentially of a biodegradable ceramic material which includes substantially linear pores aligned along the direction of desired bone growth. The implant can be in any shape suitable for use in the healing of bone voids present in bones such as long bones and facial or cranial bones.

Abstract: 1,231,729. Resistance transducers. BATTELLE DEVELOPMENT CORP. Oct. 6, 1969 [Oct. 21, 1968], No.48919/69. Heading G1N. A pressure-sensitive resistance transducer is formed from resilient material with a progressively collapsible skeletal structure e.g. latex foam, whose surfaces are coated with a layer of conductive material, the resistance between opposing external faces being decreased in compression and increased in tension. Details of suitable resilient materials and coatings are given. An element of pressure-sensitive resistance material 80, Fig. 10, is fitted with end-plate electrodes 89, using conductive cement 88. Modifications include a solid spring core Figs. 11, 22 (not shown), a bellows housing Fig. 12 (not shown) and a Bourdon tube arrangement for measuring fluid-pressure Fig. 13 (not shown). A transducer covering two load ranges is formed by stacking one resistance element on top of another, the elements having different modulii Fig. 21 (not shown). A transducer unit may include two active resistance elements 135, 136 Fig. 14, and two passive resistance elements 131, 132 for ambient temperature compensation, inter-connected as a bridge network, or four active elements in a bridge network assembled to act differentially to an applied force Figs. 16, 17 (not shown).

Abstract: 1,255,469. Light distribution and detection apparatus. SCIENTIFIC ADVANCES, Inc. April 13, 1970, No. 17536/70. Heading G1A. Apparatus for providing light of constantly proportional intensities in a plurality of light reception areas 17 on a test surface 14 (e.g. a bank note) and for detecting light reflected from said areas comprising a solid internally transparent light distributer member 11 having a recess 15 with a source of light 16 and a plurality of illumination areas 21 each with a corresponding opening 18 containing a light detector 22 and a filter 23. The surface of the member 11 and the cylindrical portion 19 of each opening 18 may be coated with a light reflective material. Centring of the test surface can be checked by means of an additional light detector 33 in a block 30, the block has a transparent groove 31 around its periphery which allows light to pass from a similar groove 26 if the test object is not correctly centred.
