Abstract: ABSTRACT An improved engine construction is disclosed having a valve train including valves and corresponding valve stems for controlling the intake and exhaust ports, cams for imparting reciprocating motion to the valves by way of the valve train, and a valve spring for biasing each valve toward its closed position and the valve train into tracking relation with the cam.  The only element of the valve train coupling a cam to a stem is a cam follower with a depression for receiving the corresponding stem end and a cam engaging surface opposite the depression with the cam follower being held captive intermediate the stem and cam solely by the spring biasing of the stem toward the cam and the engagement of the stem end and the depression.  The spring biasing is provided by a coiled wire spring having outwardly extending legs each of which engages a corresponding stem to urge the valves toward their closed position.  The bight or coiled portion of the spring is held in a relatively fixed position by a portion of the engine casting.  Another feature of the engine resides in the engine block casting which includes an exhaust gas passageway extending from an engine cylinder and including near the end thereof remote from the cylinder an enlarged cavity which defines at least a part of a muffler shell.  Numerous other elements may be cast integral with the engine block including a boss for attaching a pull rope recoil starter assembly along with an anchoring point for one end of the rewind spring of that starter assembly and retaining guides for the rope of the starter assembly.  The locator, such as a stud for the intake and exhaust poppet valve biasing spring, may also be cast integrally with the engine block.  A further feature of the engine resides in a combination crankcase breather mechanism and oil fill cap which due to its remote location from the engine crankshaft as well as the tortuous air flow path through the cap to the atmosphere minimizes the egress of oil from the engine through the breather mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE         A mixer for mixing a body of receiving liquid with solids, liquids or gases introduced therein.  The mixer includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and at least one thin annular ring mounted on the disk-like member spaced from, parallel to and con-centric with it.  The flow of liquid perpendicular to the annular ring through the inner opening thereof, when the mixer is immersed and rotating in the body of receiving liquid, is unimpeded by any structural mem-ber.  The annular ring may be mounted on either side of the disk, and a plurality of annular rings may be employed.  The annular ring or rings may be mounted on the disk-like member by at least three elongated support posts spaced equally around the outer perimeter of the disk, the transverse cross-section of each post being curvilinear, preferably circular, in shape.  The mixer is disclosed for use in a tank.  The vertical position of the rotatable disk-like member in the tank produces a flow pattern in the body of receiving liquid that is characteristic of the particular position selected.

In a first step, a strip of tape is applied onto the sheet of veneer close to each of its edges to be trimmed.  In a second, subsequent step, the tape-reinforced edges of the sheet of veneer are trimmed by shear, preferably using a pair of overlapping cutting discs positioned to produce the requested shearing action.  A machine especially designed for carrying out this method is also disclosed.

Abstract: ABSTRACT     The protection circuit for inner elements such as metal insulator semiconductor (MIS) field effect transistors in a semiconductor device of high packing density has been improved. The protection circuit comprises protective elements of two types.  The first one has a deep diffusion region providing the element with high surge capacity (an ability to withstand incoming surge energy) and the other one has a shallow diffusion region providing a low breakdown voltage.  With the combination of these protective elements of two different types, the protection cir-cuit can withstand a high input surge energy and, at the same time, provide a low protection voltage suitable to protect the inner elements from breakdown.

Abstract: A B S T R A C T             IMPROVEMENTS RELATING TO SEISMIC SURVEYING        A 3-dimensional seismic survey of subsurface strata produces reflection samples relating to common source-detector midpoints on a rectangular grid in which the lines of the grid in at least one direction are in groups in which the lines are more closely spaced than the nearest lines in adjacent group.  The bunching of lines into groups has no effect on the accuracy of the crossline interpolation but enables a group of lines to be surveyed at the same time by a vessel using more than one separate seismic source and/or more than one streamer value of seismic receivers.  It is of particular value when the survey has widely spaced lines so that the surveying of two lines of an evenly spaced grid at once would involve an impractically wide separation of the sources or streamer cables.

Abstract: Abstract High Voltage Connector A high voltage  connector is provided for interconnecting a power cable to an apparatus such as a transformer. The cable is securely coupled to the connector, which is then mounted on to the transformer bushing.  The bushing and cable electrical contacts inside the connector are spaced apart, and electrical connection is achieved therebetween by inserting a continuity plug into a socket of the connector.  Electrical isolation between the cable and transformer may be effected without physically moving either piece of equipment, by removing the continuity plug and replacing it with another plug that introduces sufficient electrical insulation between the equipment contacts to allow operating and test voltages to be applied to one of the cable and transformer without flashover occurring to the other of said pieces of equipment.  Other interchangeable plugs may provide earthing for a selected one of the pieces of equipment, also without requiring physical movement of the equipment.

Abstract: ABSTRACT OF THE DISCLOSURE        Novel plasmidic expression vehicles and methods of using them in the production of useful polypeptides by recombinant bacteria are described.  The plasmids employ a tryptophan  promoter-operator system from which the attenuator region ordinarily present has been deleted.          Bacteria containing the plasmids can accordingly be repressed by the addition of tryptophan against expression of desired polypeptides coded for by inserted genes while they are grown to levels suitable for industrial-scale production.  Additive tryptophan may then be withdrawn, essentially derepressing the pathway and permitting efficient production of the desired product in high yield.

Abstract: Abstract:          A transfer sheet comprises a flexible substrate, a laminated image part composed of a metal layer and a printed film layer, and an adhesive layer formed on -the image part. The printed film layer has an elongation at its breaking point greater than approximately 4%, and has a thickness greater than approximately 4 µm.  The peel strength between the sub-strate and the metal layer is smaller than approximately 10 g/25mm width, and the adhesion strength between the metal layer and the printed film layer and between the printed film layer and the adhesive layer is greater than approximately 4 kg/cm2.  Because of these values, the transfer sheet permits the image part including the metal layer to be released with-out breakage and provides improved transfer characteristics, especially onto curved surfaces.

Abstract: ABSTRACT   An improved composite, pre-stressed structural member and method of forming such a member of the type provided by upside down forming which includes connecting the steel beams of the composite member to the upper side of a mold so that a parallel deflection of the mold and beams occurs as the mold is filled with concrete.  The improvement comprises utilizing a steel beam having a flange at or near the neutral axis with respect to a vertical deflection of the support member.  After the composite structure is formed, the flange is away from the neutral axis with respect to a vertical deflection of the composite structure.  This flange, therefore, significantly increases the section modu-lus of the composite structure while not adding signifi-cantly to the resistance to bending of the beam during pre-stressing.  Stacked and welded I-beams are an example of a support in accordance with this invention.
