Abstract: VALUE MEANS                          Abstract A valve means to be  installed in a string of drill pipe above a bottom hole positive displacement motor com-prises a hollow housing having an inlet and an outlet for the passage of a drilling fluid therethrough, the wall of the housing having through holes to communicate the inte-rior of the housing with the annular space of the well bo-re. Secured in the housing substantially above the through holes is a transverse plate or partition provided with a plurality of calibrated openings intended to produce a pressure drop. The housing further accommodates a chamber communicating with the through holes and provided with an open face in the upper portion thereof, the chamber being arranged such that through passages are formed between the chamber and the housing. The housing further comprises a se-aling couple intended to prevent the through holes from com-municating with the interior of the housing in the course of drilling operation. A valve seat of the couple is adapted to fit the circumference of the open face in the upper portion of the chamber, whereas a spring-loaded valve ele-ment of the couple is capable of being moved axially under the action of the pressure drop, the valve element having a tail-piece the end of which is adapted at least to level with the upper surface of the partition.

Abstract: FEED SYSTEM FOR RADIATING ELLIPTICALLY POLARIZED ELECTROMAGNETIC WAVES IN MICROWAVE OVEN                 ABSTRACT OF THE DISCLOSURE          The heating uniformity of a microwave oven is significantly improved by a feed that radiates elliptically polarized electromagnetic waves.  A pair of corssed slots in the feed rectangular waveguide has directional characteristics and radiates energy with right-hand and left-hand circular polarization.  A variable phase shifter in the waveguide changes the phase of one of the polarizations. Both polarizations interfere in the oven cavity and produce rotating elliptically polarized waves.  The circular polarizing element can be a 3-dB hybrid coupler or a turnstile junction.

Abstract: ABSTRACT OF THE INVENTION     The invention relates to a process for producing ready-to-use slats from semifinished slat portions for a slatted Venetian blind with vertically directed slats, as well as retaining means suitable for the same.  In connection with the process the slat portions are in each case cut at their free lower end to the length corresponding to the installation height, plus an extra length taking account of a wrap-over portion.  The wrap-over portion of a slat is in each case wrapped over at a bending edge predetermined by the use length.  The lower end part of a slat is provided in the vicinity of a wrap-over portion with a system of perforations consisting of at least two holes for receiving the retaining pins of a retaining means.  The retaining pins are passed through the holes and locked.  The retaining means is characterized in that the retaining pins (41) to be passed through the holes (37, 37') have a substantially cylindrical pass-through portion, (42), whose diameter (d) is substantially the same as the diameter of the holes (37, 37') and which can be locked by means of a locking means (43) and that the pass-through portion (42) is followed by a head (44) which is larger than the latter and prevents the pin from slipping through the particular hole (37 or 37') (Fig. 6).

Abstract: Abstract of the Disclosure A circuitless particle beam device for relatively high frequency amplifier or oscillator applications that eliminates the requirement for an internal RF slow wave structure.  A circularly polarized RF energy wave propa-gates on a relatively high density particle beam within an oversized waveguide and interacts with the beam which exhibits a relatively high dielectric con-stant.  The high density beam acts as an active dielectric waveguide serving the dual purpose of a slow wave circuit and amplification source, and according-ly guides and amplifies the RF energy when a condition of beam and wave syn-chronism is met.

Abstract: ROW DRIVER CIRCUIT FOR SEMICONDUCTOR MEMORY            ABSTRACT   A circuit (10) is disclosed for use in a semiconductor integrated circuit memory.  The integrated circuit memory includes row lines (102-108) which serve to activate the access transistors for memory cells (102a-108a) within the memory circuit.  A row decoder circuit (36) receives a plurality of first address bits and produces a drive signal output when the decoder circuit is selected.  A transition detector circuit (24) produces a transition signal whenever the state of any of the address bits is changed.  A clock decoder circuit receives a plurality of second address bits together with the transition signal to produce a selected clock signal (.PHI.A-.PHI.D)-  The combination of the transition signal and the output of the row decoder circuit (36) serves to precharge the gate terminals of the row driver transistors (80-86) for the row lines (102-108).  The selected row line receives the active state of the clock signal (.PHI.A-.PHI.D) which causes the gate terminal of the selected row driver transistor to be capacitively coupled to a higher voltage than the clock signal to therefore supply the full clock signal voltage to the row line (102-108).  The voltage on the row line then activates the access transistors (118, 120) for the memory cells (106a) on the row line (106). This enables a maximum charge to be stored in or read from the memory cell (106a).

Abstract: ABSTRACT          A process for preparing polycarbonate type nonionic surfactant compositions comprising monohydroxy alcohols capped with polycarbonate groups.  The sur-factant compositions comprise aliphatic, nonaromatic cycloaliphatic or aromatic alcohols which have been capped with block polycarbonate groups formed by the reaction of the alcohols with ethylene carbonate in the presence of an alkali metal salt catalyst.  The sur-factant properties are varied by first reacting the alcohols with ethylene oxide to form a block polyether group cap on the alcohols before the reaction with ethylene carbonate or by further reacting the poly-carbonate capped alcohols with ethylene oxide to form a terminal polyether block group.  The surfactants are formed by reacting 2-20 moles ethylene carbonate and 3-50 moles ethylene oxide per mole of the alcohols.   27,098A-F

Abstract: ABSTRACT OF THE DISCLOSURE          OPTICAL FIBER CONNECTOR AND HOUSING STRUCTURE FOR OTHER APPLICATIONS         The hybrid connector concurrently connects electrical conductors and optical fibers terminated in the connector to electrical conductors and optical fibers respectively terminated in a mating array of electrical contacts and optical fiber connecting elements.  This mating array may be in a mating connector.  Each optical fiber is clamped within the connector housing and surrounded by a guide which extends from the clamp toward the mating end of the housing for abutting the fiber connection elements of the mating array.  The clamp and the fiber guide form the optical fiber connector and are mounted within the housing for retractive movement against spring action in a direction away from the connector mating end relative to the electrical contacts of the connector.  Upon the mating engagement of the connector with the array of electrical con-tacts and optical fiber connecting elements, the clamp and the fiber encompassing member cooperate to gauge the connections between an optical fiber held by the clamp and another optical fiber of the array independently of the connection between the electrical contacts of the connector and mating electrical contacts of the array.  The connector housing structure com-prises two hermaphroditic-housing half shells which may be coupled together to form a connector housing that can be inter-locked to another housing similarly formed from two half shells by sliding the two connector housings together so that flex-ible fingers on one housing engage latches on the other housing. Cantilever release arms are positioned adjacent to the latches to facilitate disconnection of two interlocked connector hous-ings.
