Abstract: ABSTRACT           A method of in vitro clonal propagation of plantlets from excised gymnosperm tissue in which the excised tissue is pulse treated on a nutrient medium containing at least about 10 mg/L, preferably at least about 20 mg/L, of a cytokinin for a time sufficient to induce formation of adventitious buds on the excised tissue and is then transferred to a nutrient medium free of exogenous growth factors and maintained thereon until the induced adventitious buds produce rootable shoots.          The rootable shoots may then be rooted by conventional means but preferably are pulse treated on a nutrient medium containing a phenolic compound, preferably in an amount of at least about 5 mg/L, and an auxin, preferably in an amount of at least about 5 mg/L, for a time sufficient to induce formation of adventitious roots and then transferred to a nutrient medium free of exogenous growth factors until the shoots are rooted.

Abstract: A B S T R A C T     An apparatus for the automatic dispensing of a gas from a bank of supply tanks to a cylinder. The apparatus is particularly suitable for the charging of vehicle cylinders with Compressed Natural Gas (C.M.G.). The C.N.G. is stored in tanks held  at progressively higher pressures charging of a cylinder being achieved by way of the pressure differential. As this approaches equalisation the apparatus switches up to a supply tank at a higher pressure to thus maintain the charge flow. The apparatus includes control circuitry and processor units to provide the above functions together with various safety checks and monitoring of the charge.

Abstract: Abstract A gas plug for metallurgical vessels consists of a porous, gas-permeable brick of refractory material, a gas-tight partial encasing for the brick comprising a metal jacket extending around the lateral circumferential area of the brick and a metal cover for the outer face of the brick, and a pipe for supplying gas to a central gas inlet orifice of the metal cover.  To prevent clogging of the brick in the gas outlet area and in order thereby to ensure purge readi-ness, a constricted cross-section is provided in the gas supply pipe at a distance from the gas inlet orifice of the metal cover, there being provided in the pipe between the metal cover and the constricted cross-section a closure body, which is movable at least in the axial direction of the gas supply pipe and is, for example, a copper ball or the like, the cross-section of which is smaller than the inside diameter of the gas supply pipe and greater than the constricted cross-section.  The closure body, together with the constricted cross-section, thereby forms a non-return valve, which prevents a pressure drop occurring in the brick after switching off the gas supply.

Abstract: A twin hydrocyclone used for instance in cellulose and paper mills for purifying pulp suspension said twin hydrocyclone consisting of two hydrocyclones mounted with their larger ends against each other and having one common infeed connector     and one common purified fraction discharge connector    . The hydrocyclones of prior art have the drawback of complex design and of division of the feed flow causing disturbances in the feed flow in view of the hydro-cyclone's operation. The twin hydrocyclone of the present inven-tion, meant to solve these problems, is characterized in that the feed flow from the common infeed connector     of the hydrocyclones is directed to each hydrocyclone as a separate feed flow by means of a helical member     the helices of which constitute, in each hydrocyclone, feeding ducts confined by the walls of the hydro-cyclones.

Abstract: Abstract of the Disclosure A system for filtration of matter from a liquid suspension through a membrane uses a rotor within a concentric shell rotating with a surface velocity which, together with the rotor-shell gap and suspension viscosity, establishes vigorous vortex cells about the rotor.  At least one of the rotor and shell surfaces include a filter membrane. Tangential velocity components at the membrane surface constantly sweep the membrane surface to limit cell deposition tendencies while constantly replenishing the medium to be filtered. The vortex cells are established along the length of the membrane despite the constant extraction of filtrate and the resultant change in physical characteristics of the suspension.

Abstract: ABSTRACT           A motor-compressor unit comprises a motor including a magnetizable stator; an armature oscillatable about the motor shaft axis; two coils arranged opposite each other on the stator; and a magnetizable core extending between the coils.  The stator has opposed sections spaced from each other and arranged to define air gaps between such stator sections and the core at the end faces of the coils remote from each other, such air gaps being concentric about the motor shaft axis.  A permanent magnet is disposed between each stator section and the core, a pole of each magnet facing the core.  A plurality of pole elements is associated with the armature and is arranged such that oscillation of the armature causes one pole element to move into its respective air gap and another pole element to move out of its respective air gap.  The coils and the core are arranged such that passage of an alternating current through the coils causes flux alternately to increase in a first air gap and to decrease in a second air gap and then to decrease in the first air gap and to increase in the second air gap.  The compressor includes a linearly reciprocating piston, and a lever connecting such piston to the motor shaft.

Abstract: PALLET BASE ASSEMBLY FOR A SHIPPING CONTAINER A pallet base assembly for a shipping container, which includes a pallet base and two cargo supports mounted thereon. The two cargo supports are also utilized to form ramps for unloading the cargo from the base. Each cargo support includes a relatively flat support element providing a ramp surface when the support is used as a ramp and a cushioning element which is interposed between the support element and the cargo when the support is mounted on the pallet base for supporting the cargo. The illustrated form of the pallet base assembly further includes two deformable cushioning elements, mounted on the pallet base, to serve as the principal cargo supports. Each deformable cushioning element includes an opening within which is received a removable support insert. Removal of the support insert weakens the deformable cushioning element, allowing the element to deform, lowering the cargo onto the pallet base.

Abstract: ADJUNCT MACHINE              Abstract of the Disclosure Adjunct virtual machines are disclosed that are connected to an existing base virtual machine to provide for the creation of service processors each providing a service to the base virtual machine.  All communication with the user takes place through one console that is shared by the base virtual machine and its adjunct virtual machine.  That is, all messages and responses between the base virtual machine and the adjunct virtual machines are directed to only one console such that each adjunct machine does not require its own separate console.  Even though only one console is used, there is no requirement for one machine to log off while an operating system control program (SCP) function is executing in the other machine.  As a result, implementation of the adjunct virtual machine permits the construction of host SCP console functions that have sustaining dialogs with the user while all other SCP functions are available to the user during the dialog.  A single directory is used to define the architecture of the adjunct virtual machine which can be used, as a prototype, by all base virtual machines. The adjunct machine gains control when it is dispatched with a suitable program status word.
