Title: Half-turn valve
Inventor: SIVER CHESTER A
IPC: F16K5/00
Filed: 1986-06-26
Granted: 1990-12-04
Abstract: ABSTRACT      A plug valve assembly employs a stem having a threaded end, and a shiftable locking key to alternatively interengage the plug with either the stem or the bonnet.  When the plug is locked to the bonnet by the key, the threaded part of the shaft will initially lift it from its seat; shifting the key will permit the plug to be rotated by the shaft to open the valve, and the interengagement established by the key will enable return of the plug to orient it for closure.

Title: Control device for a pump with adjustable flow
Inventor: ENTWISTLE RICHARD T
IPC: F04B49/00
Filed: 1986-12-22
Granted: 1992-05-26
Abstract: Abstract A control  device for a pump with adjustable  flow comprises a control valve (32) with a servo input (38).  A safety valve (40) responds in the case of a fault, separates the servo input (38) from a servo conduit (41) at servo pressure (P2), and connects it to an auxiliary conduit (27) at a resetting pressure  (P3).   A resetting pressure generator (28)  can be actuated depending on the position of the adjusting apparatus (9) and, until reaching the zero position, delivers a resetting pressure (P3) of such a size that the control valve (32) is moved in a direction driving the adjusting apparatus (9) to the zero position.   In this way, one obtains automatic resetting to the zero position when there is a fault.     Fig. 1.

Title: Near-linear spring connect structure for flexible interconnect circuits
Inventor: HARMON JOHN P
IPC: H05K3/36
Filed: 1987-03-19
Granted: 1991-12-31
Abstract: Abstract A printhead for a thermal ink jet printer of the like is brought into good electrical contact with raised electrical contacts on a flexible interconnect circuit by the use of a molded near-linear spring connect structure. This novel structure includes a horizontal central locating member form which a plurality of resilient hollow cylinders extend vertically upward and in alignment with the electri-cal contacts on the flexible interconnect circuit. Since there is a near-linear deflection of the cylinder walls with increasing force applied thereto, good electrical contact is achieved between the printhead and the flex circuit using a minimum of force, thereby minimizing the likelihood of damage to the printhead.

Title: Process to produce a high methane content gas mixture from coal
Inventor: BRUNO GIACOMO
IPC: C10J3/02
Filed: 1987-09-09
Granted: 1994-09-27
Abstract: ABSTRACT OF THE DISCLOSURE:            A  process  is  disclosed  for  producing  a  high methane content gas mixture from coal.  In this process the coal is first ground to a particle size not greater than 5 mm, and preferably not larger than 2 mm.  Then, one or more alkali and/or alkali-earth compounds are added to the ground coal, wherein the alkali or alkali-earth ions are in an amount within a range of from 4% to 20% by weight relatively to dry,  ash-free coal.   The additive-containing coal is possibly dried and possibly pelletized,  so as to obtain pellets whose maximum dimension lies within the range of from 3 mm. to 5 cm. or preferably of from 3 mm to 2 cm. Then the additive-containing coal is gasified to produce gas from the coal and the so produced gas is subjected to methanation,  in  one  single  step  with  a  fixed  bed  of countercurrently descending coal with steam, and in the presence of an amount of air not larger than 35% by weight, relatively to the ash-free dry coal and/or of an amount of essentially pure oxygen in an amount within the range of from 1 to 25% weight relatively to the ash-free dry coal. This gasification and methanation step is carried out at a pressure higher than 25 abs.atm and at a temperature of from 400 to 850°C, preferably of from 450 to 750°C.  Then the unreacted  steam and the condensible compounds that are formed are removed  from  the  gas  produced  during the gasification and methanation step and finally the acidic gases are removed from the high methane content gas mixture that is obtained.

Inventor: OBERSTE-PADTBERG RUDIGER

Granted: 1991-05-07
Abstract: ABSTRACT     The invention concerns a new process for plugging and / or consolidating a permeable geological formation, notably when traversed by a borehole.    The process, according to this invention, comprises the following steps : a) insertion into the formation of an overdelayed gelling compound, composed of a gelable material and a hardener, for which the setting time is considerably longer than the suitable positioning time for the composition, in such a way that this permeates the formation over a significant distance. b) insertion, after a mechanical or fluid plug, of a rapid-action gelling agent, which causes the instantaneous gelling of that part of the overdelayed gelling compound in the immediate neighbourhood of the interface between the zone to be treated and the borehole. Thus preventing displacement of the overdelayed gelling compound toward the interior of the formation. The resultant gelling being both resistant and correctly placed.    The invention application is to oil, gas, water or geothermal drillings.

Title: Electrodes for use in electrochemical processes
Inventor: STEWART RAY F
IPC: C23F13/16
Filed: 1988-02-08
Granted: 1994-08-02
Abstract: ABSTRACT OF THE DISCLOSURE      Electrodes for electrochemical processes, especially anodes for the cathodic protection of metal substrates, e.g.  reinforcing bars in concrete, comprise a conductive core which acts as a current-distributing member, an outer member which provides an electrochemically active outer surface, and an intermediate member composed of a material which is of higher resistivity, and/or which is less electrochemically active, than the material of the outer member.  The higher the resistivity of the inter-mediate member, the more regular the current distribution along the length of the electrode.  When the intermediate member is less electrochemically active, this protects the core from corrosion if the outer member is damaged by physical means or through electrochemical erosion. Preferably at least one of the intermediate member and the outer member is composed of a conductive polymer, especially one comprising carbon black or graphite as conductive filler.
