Abstract: ABSTRACT:          Semiconductor device.         The thermal behaviour of a semiconductor body (2) is considerably improved by giving parts of high and equal dissipation (3, 31, 32, 33, 34) the same surface area and situating these regions so that the edge (5, 6) of the semiconductor body (2) constitutes a mirror surface for a row of such regions (3). These regions may comprise subtransistors (31, 32, 33, 34) of power transistors or a Darlington circuit. In the latter case, a further improvement is possible by thermal cross-coupling. The additional space at the edge (5, 6) which is required to apply the reflection principle can be used for non-dissipating elements.

Abstract: Title: Apparatus for and methods of bending metal strip ABSTRACT     In a bending machine, metal strip (42) is bent by a sequence of steps including longitudinal advance of the strip (42) alternating with bending of the strip by a movable tool (18) which engages and deflects the strip when the latter is restrained against longitudinal movement.  Provision is made for checking or inspecting the permanent angular deformation of each bend applied to the strip, to take account of the tendency of the metal strip to spring hack after bending.  Compensation for spring-back is achieved by use of a previously described characteristic relating displacement of the bending tool to the resultant permanent angle of bend applied to the strip.  Further compensation is provided to remove an error which can arise if the bending tool is movable along a line of action spaced from the point of bending of the strip by an amount greater than the incremental advance of the strip.

Abstract: Abstract A novel method of processing and storing human blood platelets  is disclosed which comprises  the  replacement  of about 35-45 mls of plasma per unit of blood platelets with a synthetic storage medium.   This synthetic storage medium comprises a buffered Ringers-citrate solution which prefer-ably contains a platelet permeable substrate for oxidative phosporylation.  In the resultant platelet suspension,  the amount of  glucose  available  for glycolysis  is  preferably limited to less than about 10 mM, preferably less than about 5.0 mM.   This platelet suspension  is  stored  in an oxygen permeable container at about 20°-24°C until needed for use.          Using this method and medium platelets will maintain their viability for up to as long as about 7 days.  Another form of the invention  involves obtaining  a platelet pellet  and resuspending the pellet in a medium consisting of a balanced physiologically compatible saline solution, an anticoagulant, and additives selected from nutrients, and buffering agents.

Abstract: ABSTRACT OF THE DISCLOSURE    An improvement is provided for the manufacture of perhalogenated polymer, e.g., PTFE, bonded electrodes. The formulation comprises a mixture of an active material is carbon monofluoride (otherwise known as fluorinated graphite or fluorinated carbon or CFx or (C2F)n); a conductive carbon additive, such as acetylene black or graphite; and polytetrafluoroethylene (PTFE).    The process comprises high shear mixing to cause the PTFE to fibrillate.  The mixture is then wet with a non-polymeric pore-former to make the mixture more pliable and to create micropores in the electrode when the solution is removed by evaporation.  The wet mixture is then sequentially suitably formed into a, e.g., extruded, or calendered or pressed to flatten the mixture to a thin sheet and rolled up and folded and pressed out again until a uniform sheet is obtained and the like.    The resulting product affords a sheet which is relatively flexible, and stronger and allows a lower PTFE loading than has been obtained with other electrode sheet materials formed with fibrillatable polymers.  The higher the PTFE content, the higher the voltage losses for the electrode.

Abstract: Application Of:  James E. Nocek, et al For:  Method For Quantitating Non-Structural Carbohydrates in Feedstuffs and Ration Formulations Based Thereon Abstract Of The Disclosure A novel method of determining the portion of a given dairy cow feedstuff which is attributable to non-structural carbohy-drates is disclosed.  The method includes the steps of analy-tically determining the percentages of crude protein, lipid and ash in the dry matter concentration of a first feed sample, and in the neutral detergent fiber which has been separated from the soluble matter of a second sample of the same feed, and subtracting the amounts of crude protein, lipid and ash in the neutral detergent fiber from the respective amounts of the same substances in the original sample.  The three difference figures are totaled and subtracted from the percentage of the second sample represented by neutral detergent solubles, i.e., 100-neutral detergent fiber, thereby providing an accurate indication of the percentage of non-structural carbohydrate in the feedstuff.  The method is applied to both forages and grains, and is employed in the formulation of dairy cow rations wherein ration is adjusted to optimize milk production, the preferred percentage being from about 30% to about 45% depending on forage type.

Abstract: ABSTRACT      A highly portable pressure intensifier for use with a borehole dilatometer head having an expandable body defining an internal cavity to measure deformation properties of in-situ rock masses.  The housing of the intensifier comprises two axially aligned interconnecting cylinders, one of which is of substantially larger diameter. The larger cylinder has a reciprocating piston mounted therein, the piston having a plunger portion which extends axially into the smaller cylinder.  The smaller cylinder is connected to the cavity of the dilatometer head by means of high pressure tubing.  The larger cylinder is filled ahead of the piston with a first working liquid. The second cylinder, the dilatometer head cavity and the interconnecting tubing are filled with a second working liquid.  Increasing the pressure of the first working liquid displaces the plunger portion into the smaller cylinder, substantially increasing the pressure of the second working liquid, which latter increase causes the dilatometer head to expand so as to deform the rock of the borehole in which it is placed.  A pressure transducer and a linear variable differential transformer are provided for deriving signals representing changes in pressure and volume respectively.
