Abstract: SLAVE SHIP HANDLING     ABSTRACT     In order to expedite the passage of vessels through a locked canal system it is advantageous to eliminate the lines handling procedure and associated manoeuvring by introducing techniques long proven in the materials handling discipline.     To this end powered rotarary cushion fenders are introduced along facing lock walls mounted on axes which can be extended towards one another across the width of the lock such that the cushion fenders will embrace between them any vessels entering or leaving the lock. The said axes are also arranged to follow the level of the water within the lock so that they will rise and/or fall with the vessel as the lock is filled or emptied.     The cushion fenders are arranged to rotate in union for the purpose of feeding a vessel into or out of a lock without the assistance of the vessels own machinery or that of tugs.     SPECIFICATON     This invention relates to means for assisting a ship to transit one or more locks in a canal system by providing a plurality of opposed pairs of autorotatable fenders adjustably mounted in relation to the lock basin walls such that they may be relocated to suit the differing configuration of individual ship hulls entered between them for the purpose of locating, advancing, retarding, and stopping said ship hull or "Slave Ship" transmitting a lock so provided. One preferred such means is provided by equipping each lock basin with a plurality of pairs of opposed autorotatable fender wheels rotatable about movable vertical axes such that the perimeter of each said fender wheel may be brought into positive contact with one or other side of an entering "Slave Ship" hull to thereby locate and restrain said "Slave Ship's" hull between said opposed fender wheels and to thereby propel said "Slave Ship" through a lock system by rotation of said fender wheels without the intervention of the said "Slave Ship's" machinery or labour.

Abstract: ABSTRACT      A ball valve is provided especially for use between adjacent sections of a pipe line conducting an inflammable fluid and comprises a valve housing, a valve ball (2) in the housing and having a through passage, a trunnion in the housing projecting into a first socket in the ball, and a control shaft projecting into and drivingly engaging a second socket in the ball diametrally opposed to the first socket. A pair of annular valve seat members (4) spaced axially of the pipe line carry sealing rings (8), spring means (9) urging the seat members towards the ball,  Each seat member at its end adjacent the spring means has a frusto-conical portion (11) which tapers from a shoulder (12) on the seat member towards the end face (4A) of the latter.  A graphite ring (13) is fitted between the frust-conical portion and the adjacent peripheral wall of the housing and a first spacer ring (14) is located between  the graphite ring and the shoulder.  Furthermore, an annular pressure plate (15) is located between the end face of the seal member and the spring means and is abutted by the latter and has an annular lip (15A) abutting the graphite ring.  Additionally, a second spacer ring (16) is provided between the end face of the seat member and the pressure plates.  In the event of fire in the pipe line, the sealing ring and spacer rings disintegrate so that the spring means pushes the seat member into metal-to-metal sealing contact with the ball, and pushes the pressure plate relative to the seat member so that the lip on the pressure plate pushes the graphite ring along the frusto-conical portion towards the shoulder so that the graphite ring becomes tightly wedged between the frusto-conical portion and the adjacent peripheral wall of the housing and seals the clearance passage therebetween against the spread of fire therealong.

Abstract: PRESSURE DIFFERENTIAL CIRCULATING VALVE         ABSTRACT OF THE DISCLOSURE         Disclosed is a pressure differential circulating valve which can be connected to and form a portion of the tubing string disposed in casing for flow of fluid from a formation traversed by the casing and the tubing. Advantageously, the pressure dif-ferential circulating valve has an unrestricted passageway of substantially the same size and shape as that of the tubing string, yet is small enough in external diameter to be disposed in normal casing set in a well bore, can be set to open at any flow pressure and can be placed at any depth. Thus, in pumping fluids down the tubing, such as hot oil to remove paraffin from the inside of the tubing and pump rods and the like, or other treating fluids, such as to treat corrosion problems, the pressure dif-ferential circulating valve opens at the predetermined pressure permitting flow of fluid therethrough into the annulus between the casing and tubing string. The pressure differential cir-culating valve automatically closes when the flow pressure drops to below the predetermined pressure, such as normal flow pressures. Also, it the flow line from the well becomes plugged, or in the event of human error in closing a valve and there is a buildup of flow pressure in the tubing string and hence in the pressure differential circulating valve, it will open and circulate fluid in the annulus until the problem is corrected.

Abstract: 6694     INVENTORS: J?RG MUGGLI and GUSTAV PFISTER         INVENTION: ALARM DEVICE WITH A CONDITION SENSOR ELEMENT                        ABSTRACT OF THE DISCLOSURE                       In an alarm installation containing a central evaluation unit and alarm devices arranged re-motely therefrom, the transmission of energy from a radiation source and the reporting back of the signal occurs exclusively according to optical principles by means of radiation conducting elements, so-called light guides or conductors, by means of which the alarm de-vices are connected with the evaluation device. The alarm devices contain a preferably high-ohm sensor element, for instance a smoke-sensitive ionization chamber, whose operating voltage is infed by means of a solar cell which is irradiated by a light guide and whose output signal is fed back to the evaluation device by means of a high-ohm electrical transducer and a light guide. Such type alarm installation preferably is used for fire detection purposes, for gas, smoke temperature detection or intrusion protection, and is particularly suitable for use in an explosion-endangered environment or one subjected to electrical disturbances.

Abstract: A b s t r a c t A light-guide unit comprises coaxially disposed a light forming and a light transmitting rods made from a light-perme-able, corrosion-resistant refractory material, in particular from a synthetic corundum. The length of the first of said rods is equal to the thickness of the metallized layer of the lining, and that of the other rod is equal to the non-metall-ized portion of the lining. The rods are connected to each other through a protection sleeve made from a material featur-ing plasticity at the operating temperature of the lining, and are disposed in a tube filled with two different refractor-materials. The tube portion wherein the light forming rod is disposed is filled with a material having a sintering tempera-ture not higher than the sintering temperature of the lining, and whose resistance to action of the products of melting is similar to that of the lining. At the operating temperature of the lining this material has the same linear expansion coeffi-cient as the said rods, and forms a viscous mass which does not fuse with the light forming rod. Silicon oxide powder is used, in particular, as said refractory material.  The tube portion wherein the light transmitting rod is disposed is fil-led with a material having a sintering temperature higher than the operating temperature and the sintering temperature of the lining, which refractory material may be, for instance, corun-dum powder.     Such construction of the proposed light-guide unit prov-ides for a flexible connection between the component members of the unit, due to which the probability of its being damaged is lower, and the light transmitting rod can be used repeatedly.

Abstract: 1197.006 S P E C I F I C A T I O N            RADIATION INSPECTION SYSTEM FOR A MATERIAL MAKING    APPARATUS AND METHOD USING A BETA RAY GAUGE               INVENTOR:  COLE H. BAKER     ABSTRACT OF THE DISCLOSURE     The beta ray gauge is augmented with a radiation inspection system for automatically improving products formed into a continuous web such as non-woven paper, non-woven textiles, plastics, etc.  For example, the basis weight of a continuous web of paper is measured by passing the web through a beta ray gauge which generates a first signal based on the weight of the paper web.  The first signal generated by the beta ray gauge is compared with a predetermined preset reference signal representing the basis weight desired.  After the beta ray gauge measures the basis weight in the paper making process, a light inspec-tion system applies a light source across the paper web and detects the light emanating therefrom to provide a second signal based on the characteristics of the paper web.  The light inspection system continuously generates the second signal across the entire width of the web, and accordingly rapidly inspects the entire web with greater spatial resolution than the beta gauge which is stationary or slow moving.  The first and second signals are compared producing a control signal which is used to regulate the dispensing of the paper stock forming the continuous paper web or to otherwise monitor and grade the continuous web output.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method of using the same to separate a heavy crude oil emulsion into gas, brine and oil, as the emulsion flows longitudinally through first, second, and third elongate zones of a treater.  Heat is applied to the emulsion in the first zone to allow free brine and gas to separate therefrom, and in the second zone to further reduce oil vis-cosity and thus allow the emulsified brine to separate.  Oil thus heated containing the remaining emulsified brine flows in horizontal stream flow into the third zone to be subjected to at least one horizontal high potential electrical field. In the presence of this electrostatic field the dipole mole-cular structure of water promotes the coalescing of droplets of brine remaining therein into drops.  These drops of brine then settle by gravity to the bottom of the third zone.  A wall maintains the liquid level in the third zone at an elevation where the electrodes that supply the high potential electrical field are at all times immersed in the oil, and also prevents the brine-free oil in the reservoir from comingling with oil that is being treated in the third zone.  Gas separating from the emulsion accumulates in the upper portion of the first, second and third zones and water in the lower portion of the zones.  The gas and brine that so accumulate are withdrawn to desired external location as the treating operation proceeds.  The electrodes forming the electrostatic grid are adjustably mounted to form variable horizontal gaps which may be modified for optimum electro-static coalescing.

Abstract: ABSTRACT OF THE DISCLOSURE          A  method is disclosed for improving the ecological conditions in a thermally or chemically  stratified lake or other water basin especially as regards the oxygen content of its waters at greater depth.  The method involves conducting the topwater from the same water body or from another source into the sub-water close to the bottom where it exerts a favourable effect on this deep water's oxygen content and also on its temperature in the respect that the density of this water is favourable with a view to keeping it at the desired depth and, furthermore, preventing e.g. undesirable participation of the sediment's capillary water in the oxygen economy. The topwater is propelled, e.g. through a wide tube by energy derived from an external source, or carried from higher altitude by siphon effect, and baffles may be provided at the discharge point to aid the desired distribution.  To the topwater being thus conveyed may be adjoined various chemi-cals or other beneficial agents.
