Abstract: Abstract of the Disclosure A lateral bipolar transistor has a semiconductor substrate of first conductivity type with an epitaxial layer arranged thereon of second conductivity type.  Collector and emitter zones of first con-ductivity type are laterally arranged in the epitaxial layer. A base terminal contact zone connects with the epitaxial layer and a buried layer of second conductivity type is placed in the epitaxial layer below the emitter and collector zones.  The buried layer has a doping concentration higher than the epitaxial layer so that a minority carrier current emanating from the emitter zone in a vertical direction is minimized.  A doping profile of the emitter zone and portions of the base adjacent thereto is provided such that an additional potential barrier is created adjacent to and directly beneath the emitter zone in order to further minimize minority charge carriers emanating at a vertical direction from the emitter zone.  The doping profile does not create any additional potential barrier in a lateral direction with respect to the emitter zone and the emanation of minority carriers from the emitter zone in a lateral direction is substantially uneffected.

Abstract: Application for Patent of Clarke Reynolds and Richard J. Quigley for RAIL FASTENER               ABSTRACT OF THE DISCLOSURE        A rail fastener includes a rail plate, a layer of elas-tomeric material between the plate and a support structure, and a pair of posts for laterally and longitudinally restraining the rail plate, with elastomeric material mounted between the posts and cooperating surfaces of the rail plate.  The rail plate, the layer of elastomeric material, and the support structure on which it is mounted form a shear pad.  The posts are partially embedded in the support structure and extend through respective openings in the rail plate, the inner peripheries of which are covered with elastomeric material, to provide lateral and longitudinal restraint to the rail plate.  Each of these posts is preferably formed of two parts, one of which is embedded in the support structure, and the other of which is an eccentric which is releaseably attached thereto.  Rotation of the eccentrics provides lateral and longitudinal adjustment of the rail plate with respect to the support structures, thereby providing lateral adjustment of the rail with respect to the support structure.  The elastomeric material is preferably polyurethane having a relatively high resistance to abrasion and a known, predictable and wall defined coefficient of friction.  The posts are of a size which eliminates the possibility of any move-ment thereof under ally expected lateral shear loads which may be imposed on the rail plate.

Abstract: ABSTRACT OF THE DISCLOSURE        A fuel pumping apparatus for supplying fuel to an internal combustion engine includes a plunger reciprocable within a bore, pump means for supplying fuel to the bore to urge the plun-ger in an outward direction, a cam for impating inward movement to the plunger to displace fuel form the bore through an outlet and stop means for determining the maximum outward movement of the plunger.  The stop means includes a stop member which can be positioned by first and second devices one of which determines whether excess fuel will be supplied for starting purposes and the other of which determines the normal maximum amount of fuel for operation of the engine once it has started.  The engine is super-charged and the device includes a pressure responsive diaphragm which is subject to the outlet pressure of the supercharger.  The diaphragm effects movement of a member from a first position to a second position and the member is operatively connected to a further member which determines the setting of said stop means.  In the second position of the member an increased quantity of fuel is supplied to the bore for subsequent delivery to the engine when the supercharger of the engine is in operation.

Abstract: ABSTRACT OF THE DISCLOSURE           This circuit breaker comprises closing-assist means for opposing the contact-repulsion forces developed when a high current flows through the circuit breaker.  This closing-assist means comprises spaced segments of high permeability material fixed to opposite sides of the usual movable contact rod and projecting laterally there-from.  Two stationary bridging members of high permeability material are located at opposite sides of said contact rod, and each extends between said segments when the contacts are engaged.  The segments are located in proximity to but slightly spaced from the bridging members when the contacts are engaged so that said bridging members and said segments define a high permeability path around the contact rod containing short gaps between said segments and said brid-ging members.  The flux resulting from current through the contact rod traverses said high permeability path and produces an attractive force between the bridging members and the segments acting on the segments in a direction to hold the contacts closed.      Opening-assist means of a construction similar to that of the above-described closing-assist means acts to assist an opening operation when the contacts are separated a short distance by an opening impact.

Abstract: ABSTRACT OF THE DISCLOSURE         A novel animal foodstuff and process for preparing the same is provided herein.  The feedstuff comprises (a) from 25 to 95% by weight dry-matter of at least one comminuted, solid, structured fibrous, agricultural by-product, having a low nutritional value and a length in the range be-tween 10 and 160 mm to provide structure, selected from the group consist-ing of cereal straw, leguminous straw, maize columellae, maize-husk-spacix grist, feedstuff cereal mixture, flax plant chaff, flax plant capsules, fibrous fruit peel, fibrous fruit skin and malt sprouts; and (b) from 75 to 5% by weight dry matter of at least one digestible, non-structured, in-dustrial by-product or residue with nutrient value, selected from the group consisting of whey, protein-enriched residues from milk treatment processes, molasses residues, vinasse, .alpha.-celluloses, starch, brewer's yeast, brewer's grains, brewing residues, distillery residues, fermentation residues, dregs, kieselguhr residues and chitin.  The process involves first inten-sively mixing the ingredients (a) and (b); then partially drying the mix-ture so obtained and then processing the mixture into a compressed product. The drying and processing  is such that feedstuff has a moisture content of 8 - 14% by weight, and the structured ingredient (a) retains its structured integrity.  This provides chewability and bite to the animal feedstuff. Accordingly, certain environmental problems are alleviated, capacity and load problems of certain processing plants are alleviated, and fodder pro-blems with respect to ration balancing are solved.
