Abstract: A one-piece filter plate comprises a pair of webs surrounded by a flange, the webs and flange being integral with each other and of one-piece plastic construction. A pressure medium can be introduced between the webs to force them apart to dewater a filter cake that has built up between the outer surfaces of the webs and the corresponding outer surfaces of the next-adjacent filter plates. The filter plate can be made by vulcanizing together two halves along a medial plane of symmetry.

Abstract: A measuring instrument for the depth of the periodontal cavity comprises a probe needle (2), a needle holder (3) and a handle (1). The needle (2) with the needle holder (3) is restrictedly pivotable from a start position determined by an abutment against the action of a bias spring, the deformation of which caused by the needle movement causes no substantial change of the spring force. To this end the needle holder (3) and the handle (1) each are attached to parts of a hinge (4). The hinge parts (5, 6) are biased to the closed position of the hinge (4) by a spring (8, 12, 13, 14) with a spring characteristic which is substantially flat at least within the restricted pivoting range of the hinge. 
<??>In this manner the hinge of the measuring instrument can be made compact and especially flat whereby the user of the instrument has a good view on the probe position under all circumstances. The measuring instrument is constructively simple, can be manufactured relatively cheap and can be more easily sterilized.

Abstract: Centrifuge apparatus includes a timing and control mechanism including a piston (10) to which is attached a cam (39, 51) having cam surfaces (5) which interact with flexible tubing (36) to control the rate of flow of blood through the tubing. The velocity of the piston (10) in the centrifugal force field of rotor (34) is determined by the resistance to flow of a viscous oil which the piston displaces with cylinder (12). The movement of the cam (39, 51) is, therefore, a measure of the magnitude and duration of the centrifugal force acting to process the blood.

Abstract: This invention relates to an improved integral manifold for a sprue gated multi-cavity injection molding system and a method of manufacturing the same. The manifold has an inner body portion which fits into a hollow retaining ring portion to define a circular peripheral space between them. The inner body portion is formed of a corrosion and abrasion resistant material such as stainless steel and has a number of straight melt ducts extending through it from a common inlet to spaced outlets each leading to a central bore in separate heated nozzles. The peripheral space contains an electric heating element surrounded by a highly conductive material such as copper. The manifold is manufactured by assembling the retaining ring portion on the inner body portion with the heating element in the space between them. A filler tube is located on the retaining ring portion in alignment with a filler duct therethrough and all the joints are sealed by brazing the assembly in a vacuum furnace. A copper slug is then inserted into the filler tube and the assembly is again heated in a vacuum furnace to cast the copper into the peripheral space around the heating element. This provides an integral unit with an improved combination of the characteristics of corrosion and abrasion resistance and thermal conductivity, as well as straight melt ducts which facilitate cleaning.
