Abstract: ABSTRACT OF THE DISCLOSURE       An R. F. power transistor device is disclosed wherein the common lead inductance may be controlled to any desired value from zero to relatively high values.     The transistor device includes an insulating member of beryllium oxide to one side of which there may be bonded the usual metal heat sink. On the other side of the beryllium oxide member there are metallized areas to which the input and output ground conductors are bonded, the input lead is bonded, the output lead is bonded and the collector of the transistor chip is bonded.  One plate of an MOS capacitor is bonded to the input ground lead.  In the case of grounded emitter applications, short, small wires are connected from the emitter areas of the transistor in each direction to the input ground leads and the output ground leads respectively. The base areas of the transistor are connected by short, small wire leads to the other plate areas of the MOS capacitor and to the input lead.  The metallizations to which the input ground leads and output ground leads are bonded and the input and output ground leads are separated by gaps.          This has the result of reducing the common lead inductance to as near zero as possible.  One or more short, small wire leads are jumpered across the gap to give an added, but controlled, amount of inductance.  On each side of the gap the ends of the input and output ground leads may have lateral extensions to which the jumper leads are connected at a particular lateral locations to give the desired inductance.

Abstract: MATERIALS DELIVERY SYSTEM FOR OFFSHORE                    TERMINAL AND THE LIKE                  ABSTRACT OF THE DISCLOSURE             A spar having fluid flow lines or material con-veyors extending along the same is anchored by a ball joint, U-joint, elastic joint or the like to a base on the bottom of a body of water, such as a sea bottom.  The spar has a buoyancy chamber near its upper end for applying an upward tension thereto at all times.  When a vessel is adjacent to the upper end of the spar, tension means extends between the spar and structures on the vessel bow to couple the two together.  The tension means provides a lateral force exerted on the spar to bias the spar toward the vessel even as the latter changes position relative to the spar due to current, wave and wind action.  Several embodiments of the tension means are disclosed.  The fluid flow lines carried by the spar connect a base manifold on the bottom of a body of water with delivery hose4s or other conductors which can provide flexibility and are connected to the vessel for the transfer of crude oil and other fluids thereto.  In lieu of fluid flow lines, material conveyors carried by the spar, such as bucket or pneumatic conveyors, can be used to raise paricle material, such as manganese nodules and ore.

Abstract: SURFACTANT OIL RECOVERY PROCESS USABLE IN HIGH TEMPERATURE, HIGH SALINITY FORMATIONS               (D#74,285-1-F) ABSTRACT OF THE DISCLOSURE         Many petroleum formations contain water having high salinity and/or high concentrations of divalent ions such as calcium or magnesium dissolved therein, and are additionally at temperature from about 70°F. to about 300°F. Most surfactants suitable for use in oil recovery operations are either ineffective in high salinity or high hardness waters, or cannot tolerate the higher temperatures en-countered in many such formations.  An aqueous fluid con-taining a water soluble alkylpolyalkoxyalkyl sulfonate or alkylarylpolyalkoxyalkyl sulfonate and a water-insoluble polyethoxylated aliphatic alcohol or polyethoxylated al-kylphenol nonionic surfactant is effective in formations containing water whose salinity is from 70,000 to 220,000 parts per million total dissolved solids and also having temperatures as high as 300°F.  The fluid is phase stable over a wide range of formation temperatures and water sa-linities and hardness values.

Abstract: ABSTRACT     A power-driven drill and screwdriver includes a housing and a drive motor mounted in the housing. A case is attached to the housing and has a spindle bearing mounted therein. A first clutch is rotatably mounted in the case axially of the bearing and is operatively connected to the drive motor. An output spindle is journalled in the bearing and has a flange formed thereon. A second clutch is formed on the flange so as to be adjacent the first clutch. The output spindle is slideably mounted in the bearing so as to cause the second clutch to be movable relative to the first clutch between a first location whereat the second clutch firmly en-gages the first clutch and a second location whereat second clutch is dis-engaged from the first clutch. A spring resiliently biases the second clutch into the second location. An eccentric member is journalled in the case and is rotatable from one position corresponding to the screwdriving mode of the tool to another position corresponding to the drill mode of the tool. The eccentric member is arranged in the case with respect to the second clutch to counteract the urging force of the spring and to dis-place the second clutch into the first location when the eccentric member is rotated from one position to the other position. A handle is attached to the eccentric member at the outside wall surface of the case for man-ually rotating the eccentric member between the two positions. A first detent and a second detent coact with a detent member in the handle for defining the respective positions of the handle. The handle is connected to the eccentric member so as to cause the first detent to correspond to one of the positions and the second detent to correspond to the other one of the positions.

Abstract: Abstract Ammonia Synthesis In an ammonia synthesis process at a pressure under 120 bar abs. ammonia is recovered from incompletely reacted synthesis gas by absorption in water.  Unreacted synthesis gas is dried preparatory to further reaction by passing it through a charge of regenerable solid absorbent until that charge is loaded with water and switching its flow to a fresh or regenerated charge.  The loaded charge is regenerated by passing ammonia-containing reacted synthesis gas through it, the displaced water being separated in the ammonia absorption step.  Alternatively or additionally the water content of the unreacted synthesis gas is decreased by contacting it with liquid aqueous ammonia at below 0°C.

Abstract: A B S T R A C T The invention relates to a method of manufacturing of an electro-chemical cell or battery, consisting of a stack of plate-shaped elements, including at least two electrode elements.  The elements consist of a sheet or plate of electrode material which is mounted in a frame consisting entirely or partly of a thermoplastic material, in such a way that gas or liquid chambers are formed between the elements.  These elements contain apertures which in the completed stack form channels for the supply or removal of liquid or gas.  The thermoplastic material of adjacent elements are welded together by fusing the thermoplastic material and hardening it again. At least one of the contact faces of successive elements is pro-vided with welding ridges consisting of the thermoplastic material around the edges of the orifices and along the inside and/or outside edge(s) of the element.  The elements are attached to one another by vibration welding. The method according to the invention is particularly suited for application to the manufacture of an electrochemical cell or battery in which gas and/or liquid transport occurs, as the channels serving for this are formed in a very simple way.

Abstract: ABSTRACT:                          Low-pressure mercury vapour dis-charge lamps of  the fluorescent type are known which com-prise two nesting glass members so grooved as to provide between their nesting surfaces a circuitous ("folded") discharge path between two electrodes, the length of the discharge path being considerably greater than the physi-cal distance between the electrodes. The whole surface of each glass member is coated with luminescent material with the result that, when the lamp is in use, the portions of the members not surrounding the discharge appear dark due to their poor light transmissibility. According to the invention, these portions of the two members are not coated with luminescent material and thus act as windows for light generated in the luminescent layers facing the lamp axis. Preferably, a fluted reflector is provided inside the lamp.
