Abstract: An expansion chamber (12) has front and rear end closures (14, 16), a diffuser (18) extending axially along the chamber from a forward closure aperture (17), with at least one aperture (15) into the chamber. Discharge pipes (24) extend along the chamber and through rear closure apertures (26). - The forward ends of the pipes terminate short of the chamber closure and each has an air inlet tube (22) projecting into it, via an aperture in the closure. There is a gap between the tube and pipe. The formed restricted passage (36), together with that (35) between the pipe and closure, generates a high velocity reduced pressure zone in which the indrawn air is heated, CO in the exhaust gases is exothermally converted to COl, and the reacting gases expanded to leave the pipe at high speed.

Abstract: After preliminary-grinding to a maximum size of 6 mm the coal is micronized by wet milling in a first mill containing water and suspension-stabilizing additives, the weight ratio between the solid and water being comprised within the range of from 35/65 to 60/40 preferably 51/49; the additive content being within the range of from 0.3% to 3% by weight relative of the solid. The aqueous suspension containing the solid is micronized to a maximum size of about 20  mu m and is used as a diluent medium in a second mill; into which is fed a charge constituted by ground solid and by the above mentioned aqueous suspension, the weight ratio between the above mentioned aqueous suspension and the ground solid being within the range of 46/54 to 75/25 preferably 51/49. The milling in the second mill allows a suspension to be obtained, wherein the average size of the micronized solid is substantially unchanged and the product obtained does not require further mixing or water separation stages in order to obtain the suspension at the desired concentration.

Abstract: In an automobile, a knee bolster is provided, with either an airbag or shoulder belt, for capturing and absorbing the translational kinetic energy of the occupant's lower torso, for prevention of submarining, and for controlled rebound. The bolster includes a member for capturing and dissipating a portion of the kinetic energy of an occupant during a collision, and a member for storing another portion of said kinetic energy. A collision between the lower portion of the body of the occupant and the bolster tends to restore the body in such a way that the rebound impact against the seat is applied to the occupant's back rather than his head or neck.

Abstract: A driving device (1) for substantially linear movement of a driver (29) included in the device comprises a shaftless spiral (10) rotatable around its longitudinal axis. The spiral encloses at least one sliding body (30) which is provided with at least one element (31) projecting from the sliding body which passes between two spiral turns (16a,16b) of the spiral located adjoining one another. The sliding body co-operates by means of elements (31) with an element (60) secured against rotational movement corresponding to the rotation of the spiral which prevents the sliding body during rotation of the spiral from rotating synchronously with the same. An elongated element (22) oriented in the axial direction of the spiral (10) is connected at its one end to the sliding body (30) and at its other end to the element (60) to form the driver (29). On rotation of the spiral the sliding body (30) and consequently also the driver (29), are moved in the axial direction of the spiral for moving the element (60).

Abstract: The invention makes it possible to produce from a blank an article whose contour is altered, preferably linearly enlarged, with great precision in relation to a corresponding contour of a used model (1c). A copying machine is used in the production. The machine comprises, on the one hand, a first pair of units (1, 2) which are arranged so as to be rotatable. The model (1c) is arranged on the first unit (1) and the blank is arranged on the second unit (2). The machine also comprises a pair of second units (24, 25) in which one supports a detecting member (24a) which is brought into cooperation with the model, and the second unit supports a machining or actuating member which is brought into cooperation with and acts on the blank. The said pairs of units are displaced from and towards each other during production. In each pair of units, the units are also controlled individually so that the one unit executes second displacement movements relative to the other unit in such a way that the desired alteration is obtained.

Abstract: The invention relates to a method of separating sulphur from a cellulose cooking process of a sulphate cellulose plant and of recycling it for being reused. In the method, the sulphur is separated and recovered as odour gases produced at various stages of the process, which gases are passed to combustion of odour gases and oxidated after that by means of a catalyst into sulphur trioxide, which as an aqueous solution produces sulphuric acid. The sulphuric acid again is used for replacing the outside sulphuric acid needed by the plant. (Figure 1)

Abstract: The differential delay element includes a pair of inverters. One inverter delays the first or second edge of an individual pulse in a data bit stream. The second inverter restores the second or first edge of the pulse to maintain the pulse width of information in the data bit stream. - Preferably, the delay element has a controllable delay for positive and negative pulse edges. Each inverter acts as a level restoring stage which restores an influenced and delayed edge to a correct logic level. The cascade coupled inverters are constructed symmetrically to ensure that pulses are of equal length.
