Abstract: ABSTRACT OF THE DISCLOSURE :           Washing basin within a laundry machine wherein independently pivoting washing bars are attached at suitable spacings to the basin.  Said washing bars may be pivoted to any angle by means of the water flow.  The toughness and flexibility of the washing bars disrupt the water flow, fric-trionally engage the items being washed and knock the items so as to enhance the cleaning process.  The independently pivoting washing bars have spherical bases which are pivotably position-ed on the outer wall of the laundry basin by packing rings and sockets.  The washing bars extend through soft water proofing washers protecting caps on the inner surface of the basin wall.          When a bar is struck by the rotating water, the spherical base may freely rotate within the socket permitting the bar to rotate so as to disrupt the water flow and to frictionally engage the items being washed.  The flexing of the washing bars caused by the water flow will make more turbulent the water flow in order to facilitate the washing effect of the laundry machine.

Abstract: ABSTRACT         In the manufacture of glazing panels com-prising sheets marginally bonded together, in order to simplify and speed up production, the invention provides a new method of effecting bonding by means of a solder between at least two such sheets and at least one metallic spacer member assembled in marginal contact with such sheets and intervening therebetween, to form an assembly.  The method comprises bringing the assembly within the effective sphere of operation of a treatment means which is carried by a frame and causing such treatment means to act simultaneously on each side margin of the assembly around the whole margin of the assembly while the assembly is stationary with respect to the frame, to bond the assembly together by melting the solder.  This new method of effecting such bonding can be performed more rapidly than previously known methods in which the various side margins of such an assembly are treated successively, and is there-fore more suited to use in series production of glazing panels.  The invention also provides an apparatus for carrying this method, which is characterized in that it comprises a frame including at least three beams each of which extends along one side of the assembly, each beam being coupled at one end to a movable coupling slidable along the direction of an adjacent beam whereby the end of that beam is relatively movable along another beam in the direction of whose length its end coupling is movable, so that the size of the frame can be adjusted, treatment means carried by each of the beams arranged for simultaneous energisation to treat each side of the assembly and a support for the assembly to bring the assembly within the effective sphere of operation of the treatment means.

Abstract: ABSTRACT             The invention is concerned with a drill rod centering device including a housing connected with a ro-tating mechanism actuated by a hydraulic drive.  The center-ing device of the invention is characterized in that it has at least three link gears with roller bearings.  The roller bearings are uniformly circumferentially spaced within the housing and mounted each on a vertical spindle for radial displacement by the action of the hydraulic drive by means of the rotating mechanism and the link gears.  The roller bearings have their external side surfaces permanently urged against the drill rod to define the centering diameter.          The centering device is also provided with hydraulic valves underlying the roller bearings.  The roller bearings are spring-urged along their axes and are mounted for axial dis-placement so that upon a certain friction value developing between the rod and the roller bearings, the roller bearings travel jointly with the rod in the direction of drill to engage the hydraulic valves, whereby the valves exert a force setting the centering diameter to correspond with the drill rod diameter.

Abstract: FLUID FILLED BEDS AND THE LIKE     ABSTRACT OF THE INVENTION     Apparatus and method are disclosed which pertain to inflatable structures useful as air beds and the like.  Shape and load con-trol are facilitated by a plurality of bladders that are located within an inflatable chamber of the structure and are joined to opposed imperforate walls thereof.  The bladders are provided with vents which lend to the interior of the chamber, and upon inflation of the structure and resultant separation of the opposed walls of the chamber, the bladders are caused to extend from a flattened state, become filled with the fluid used for inflating the structure, and assume a roughly cylindrical con-voluted configuration.  Being made of a flexible, substantially non-extensible material, such as vinyl plastics, there is a limit to which the bladders can extend, and further vertical separation or lateral shifting of the attached opposed walls is thereby restrained.  When the bladders are provided with vents, they "breathe" when a physical load is applied to the inflated struc-ture or removed from it, hence, regulating resiliency by means of an "air spring" effect.

Abstract: Kockums 24 c+us/w RESILIENT POSITIONING APPARATUS     ABSTRACT OF THE DISCLOSURE           Resilient positioning apparatus for sus-taining repeated shock loads from heavy work pieces, with ability to reposition work pieces accurately and quickly with negligible loss of accuracy after long service.  Apparatus has telescoping assembly having two portions which can be accurately posi-tioned relative to each other and a gas cylinder which has a partition cooperating with one of the portions.  The partition defines a chamber with the portions of the telescoping assembly, and the cham-ber is exposed to pressurized gas which forces the partition, and with it the telescoping assembly against a datum,  When the telescoping apparatus is subjected to shock load from a work piece, it is momentarily shifted off the datum, thus cushioning the telescoping assembly, and is then quickly return-ed due to force from the gas cylinder.  The invention is simple and eliminates complex valving associated with shock absorbing hydraulic circuits and is not subjected to buckling under compression loads.

Abstract: COLOUR CATHODE-RAY TUBE APPARATUS WITH SHADOW MASK         ABSTRACT     In shadow mask colour cathode-ray tube apparatus, the shadow mask is provided with slits or rows of slots extending from side to side of the mask and a line raster is con-strained so that the lines of the raster are collinear with the slits, there being just one slit to each line of the raster. Open loop control may be used to achieve collin-earity but closed loop control is preferred.  Beam position signals may be derived from the shadow mask by sensing secondary emission from different phosphors on the gun side of the mask or by sensing currents generated in the mask.  In the preferred embodiment the beams are dithered as they traverse the raster and the difference in the currents generated by a beam at the mask and at the conductive layer at the tube screen is detected.  The first fundamental of the difference current indicates by its amplitude and phase the amount and direction of the misregistration of a beam and a slit.  Different beams are distinguished by frequency multiplexing.

Abstract: ABSTRACT OF THE DISCLOSURE Bitumen in oil sands is recovered from an in-situ or subterranean deposit thereof by forming a cavity in the deposit, sloughing or crumbling the oil sands from the cavity wall, formation of an oil-in-water emulsion from the bitumen in the sloughed material and removal of the emulsion from the cavity.  The emulsification is effected using de-aerated sodium hydroxide solution and the bitumen is recovered from the oil-in-water emulsion by inversion of the emulsion to a water-in-oil emulsion using slaked lime and dewatering of the water-in-oil emulsion.  The continuous sloughing of the oil sands from the cavity wall and formation of the emulsion from the sloughed material causes the cavity to move through the deposit.
