Abstract: ABSTRACT OF THE DISCLOSURE         An endotracheal tube holder includes a thin contoured plate fitting over the patient's nose with openings for the nostrils, a supporting member extending downward from the nose plate, and a tube holder attached to the supporting member having a C-shaped channel into which the endotracheal tube may be in-serted laterally and held firmly in place by the walls of the channel.  The contoured plate is held in place by an elastic strap attached to either side of the plate and extending around the back of the patient's head.  A pair of supplemental elastic straps are attached to the supporting member, the opposite ends being fastened to the first strap at locations near the middle of either cheek.  The supplemental straps pass through small con-stricting openings in the main strap at these locations, being squeezed and frictionally fastened to the main strap, and they may be tightened by pulling them through the openings.

Abstract: ABSTRACT OF THE DISCLOSURE         A disposable dental impression tray is provided in its bottom with a number of inlets for injection of the impression material, preferably one inlet at each tooth.  Each inlet has a connecting member, preferably defining a conical opening snugly receiving a tubular nip at the discharge end of a syringe. The syringe can thus be removably applied at any selected inlet of the tray to substantially reduce the pressure required for an accurate impression of the required area, as compared with known impression trays having only a single opening for in-jecting the impression material to obtain impression of several teeth, which often produces relatively poor impressions of the teeth remote from the opening.  The readily detachable connection between the syringe and the tray provides for quick and convenient selective injection at the desired location.  The tray is preferably produced from a generally transparent plastic material by injection molding and can thus be made as a disposable element.

Abstract: DEVICE FOR SORTING OBJECTS          Abstract of the Disclosure A device for sorting objects includes a plurality of substantially parallel and mutually transversely spaced conveyor belts on which the objects rest during their ad-vancement.  A plurality of sorting assemblies is provided, each including a plurality of sorting rollers which can be lifted from their retracted positions in which they are out of contact with the objects into their extended po-sitions in which they alternate with the conveyor belts and extend to above the same to engage the objects from below.  Rotation of the sorting rollers in one sense or the other will displace the objects to one of two lateral outputs of the respective sorting assembly, so that the sorting device distributes the objects to a number of out-puts which is twice the number of the sorting assemblies.          The sorting assemblies can be arranged in succession as considered in the advancement direction of the objects, or at several levels, or both.  All of the conveyor belts are driven by a single motor and a transmission.  The plurality of conveyor belts may consist of several sets of such con-veyor belts, each of the sets being associated at least one of the sorting assemblies.  The conveyor belts of each set are trained about respective input and output reversing rol-lers.  Transition conveyor belts may be trained about the output reversing roller of a preceding, and about the input reversing roller of a succeeding, ones of successive sorting assemblies.  The transition conveyor belt may also be used to transmit motion between the successive conveyor belt sets.

The attachment device is substantially contained within the hood portion of the vehicle and includes a pair of vertically aligned support members fastened to the frame of the vehicle.  A first pair of swinging arms are pivotally attached to the support members and extend forward thereof to merge into a single pivot point.  A second pair of swinging arms are also pivotally attached to the support members, below the points of attachment of the first pair of swinging arms and in a parallel fashion thereto.  The forward ends of the first and second pair of swinging arms support an adjustable implement.  The swinging arms are vertically adjustable by a pair of lifting means, such as hydraulic cylinders, which are pivotally attached at a lower end to the frame of the vehicle and are rotatably attached at their upper ends to the first pair of swinging arms.  By extending and retracting the hydraulic cylinders, the swinging arms can raise and lower the attached implement relative to the ground.

Abstract: S P E C I F I C A T I O N          "Method of operating a vortex bed furnace by using a dust burner  and a vortex bed furnace for carrying  out this method"               ABSTRACT OF THE DISCLOSURE         Known vortex bed furnaces have a relatively high structural volume in relation to the firing performance.  In addition, special devices are necessary for supplying the vortex bed with fuel and with sulphur-absorbing additives.  Without subdividing the bed, a partial load can only be achieved with a vortex bed furnace which differs from the full load by only a small percentage.  In order to solve these problems, it is proposed according to the invention that the fuel for the vortex bed should be blown with air via at least one dust burner, unsifted, into the combustion chamber, whereby the fine portion of the fuel conducted in is burnt in the dust flame and the coarse portion drops from the dust flame into the vortex bed.  The dust burner serves on the one hand to load the vortex bed and on the other hand to increase the relative firing performance, and can be used to improve the scope for partial load.
