Abstract: An orthodontic appliance closely adapted to a patient's teeth for holding the same securely in place and a method for forming the same. A preform having a trough formed between a labial-buccal flange and a lingual flange is designed preferably for only one of the upper or lower row of teeth. It is formed of a material which is quite hard, i.e. essentially non-resilient, and it has the property of becoming soft for non-elastic reshaping at a temperature above body temperature and below 212 DEG  F. The preform is heated and when soft it is placed within the patient's mouth and reshaped to precisely the contour of at least some if not all of the teeth of the row to which it is applied. The appliance is then cooled, preferably while still in the patient's mouth, after which the flanges are preferably trimmed back to the gum line and even beyond that for the portion of the labial-buccal flange against the labial surfaces of the anterior teeth.

Abstract: The invention relates to a mounting device for panel elements, especially for buildings and the like, which mounting device includes a number of mounting bars, which are mounted on the surface to be covered by the panel elements which are provided with a number of mounting ribs for cooperation with the mounting bars. The object is to provide a simple device of this kind, which device allows mounting without requirement for accurate alignment of the different details. This is accomplished in that each mounting bar carries a number of retaining members for cooperation with the mounting ribs. The retaining members are locked against movement perpendicularly to the longitudinal axis of the mounting bar but are freely slideable along the mounting bars to enable adjustment of the retaining members relative to the mounting ribs. Each retaining member includes two jaws facing each other, said jaws being directed outwardly at an angle to the mounting bar and at their outer ends being connected by means of a connecting member which defines an upwardly open and in the initial position of the jaws substantially trapezoidal recess, in which the mounting rib fits and which, when the panel element is pushed inwardly, closes around the mounting rib, so that the jaws retain the same.

Abstract: Procedure for preparing thermomechanical pulp from wood chips, wherein the chip flow is conducted from a storage reservoir under normal pressure through a first lock feeder into a pressurized steaming chamber, where the chips stay for a few minutes and are heated to an optimum temperature of 100 DEG  to 125 DEG  C., and from the steaming chamber through a second lock feeder to a feed means which supplies the chips into an enclosed hot refiner. In the procedure the steam discharging from the throat of the refiner against the chip flow is utilized for heating the chips in the steaming chamber, and the steam separated from the mechanical pulp is led off for use elsewhere. The steam utilized for heating the chips is conducted in complete counter-current fashion with regard to the chip flow, that is through the feed means, second lock feeder, steaming chamber, first lock feeder and reservoir under normal pressure into the open atmosphere, and the refining of the chips is carried out at a substantially higher temperature than the heating of the chips preferably not less than 135 DEG .

Abstract: A total hip joint prosthesis has a ball, replacing the ball of the hip joint ball and socket, affixed to the femur by a stem. Stem stress is reduced by providing a rounded cross-section of the stem truncated along the lateral side in the critical section subject to greatest cyclic loading. The stem is of controlled low flexibility so that when the bone cement and stem composite structure is in place, the bone is subject to a maximum percent of normal stress from bending moments. By virtue of the truncated shape and its size relative to the bone cavity, stress in the stem is minimized when the stem alone carries the load.

Abstract: A method of and apparatus for separating a medium into components of different particle masses by means of centrifugal force in equipment, e.g. cyclones, operating with turbulence free flow. The invention serves to reduce friction between a vortex and a chamber by removing part of a chamber wall from between parallel vortexes. The supporting action of a chamber wall is compensated for by colliding parallel oppositely rotating vortexes with each other at angle of 0 to 90 DEG . Adjacent to a separating vortex is a forced vortex rotating in opposite direction. Vortex separators can be built up into extensive systems with parallel vortexes positioned e.g. peripherally or in a regular square net. Thus, separating vortexes and forced vortexes alternate in such a system.

Abstract: A process for producing pig iron from iron ore concentrate, at which in a reactor vessel iron ore concentrate, coal, oxygen gas and slag formers are injected beneath the surface of a molten iron bath. According to the invention, the ratio CO2/CO in the waste gas (11) from the reactor (2) is caused to increase to a value higher than corresponding to the condition of equilibrium at atmospheric pressure. Hereby a greater heat development is caused to take place in the bath for a certain coal amount. The injected amount of coal in relation to injected amount of concentrate is predetermined to be sufficient for finally reducing pre-reduced iron ore concentrate (4) in the reactor (2). According to the invention, CO and H2 in the waste gas is passed to a pre-reduction step (1), where unreduced iron ore concentrate is pre-reduced and thereafter can be injected into the reactor. 
<??>According to a preferred embodiment, the reactor (2) is pressurized to cause the CO2/CO ratio to increase.

Abstract: A container rearranging station wherein bottles or other containers enter in single file and are discharged with several of them abreast of each other. The station is comprised of three parallel running conveyor sections. All the sections are tilted at the same angle so as to provide a smooth inclined plane. A supply conveyor on which the bottles arrive in single file is the highest of those on the inclined plane and runs at the highest speed of any of them. The adjacent intermediate conveyor runs at a slightly slower speed and the adjacent lower most discharge conveyors run at a uniform but still slower speed. Inclination angles of the conveyors between the input region of the station and the output region where the containers are abreast are preferably adjustable between 8 DEG  and 11 DEG  so that the containers drift from the supply conveyor through the intermediate conveyor to the discharge conveyor. On the highest supply conveyor side there is a guide surface or deflector which is operative to deflect the containers off of the supply conveyor if they do not drift off early enough. Only bottles with exceptionally rough bottoms generally reach the deflector. Most of the containers slide off of the supply conveyor randomly before they reach the deflector. Thus, container collisions and noise are substantially reduced.
