Abstract: 1,127,766. Drying process. PULP & PAPER RESEARCH INSTITUTE OF CANADA. 1 Nov., 1965 [27 Oct., 1964], No. 43872/64. Heading F4G. A process for drying wet porous material in the form of mats of discrete particles or continuous webs 31 comprises simultaneously subjecting the material to percolation of gas through the material by a difference in gaseous pressure between two faces of the material and to heating by radiation and convection, wherein the heating by convection is provided by hot gas having a velocity sufficient to effect transmission from laminar to turbulent flow in the boundary layer at the area where the hot gas impinges on or contacts the material. The material 31 passes about a perforated roller 15, in a compartment 11, the majority of the interior of which roller is at reduced pressure, and is simultaneously subjected to radiant heat from gas or electrically fired radiant heaters 12 while hot air at the above stated velocity enters the compartment 11 through valved lines 13. Infra-red heaters may replace the radiant heaters 12, and additional microwave, H.F., induction or conduction heating may be used. The hot air may also enter the compartment, perpendicularly, tangentially co-current or tangentially counter-current to the direction of movement of the material.

Abstract: 1,150,346. Drying and separating gases. RIMER MFG. CO. Ltd. 22 Sept., 1966 [18 Oct., 1965], No. 43957/65. Heading B1L. Compressed air or an oxygen-containing gaseous mixture is dried or fractionated by passing it alternately or consecutively at atmospheric temperature to two or more drying or fractionating vessels in such manner as to provide continuous flow through each vessel during drying or fractionation, and subsequently regenerating absorbent material in the vessels in a timed cycle solely by vacuum and without purging by reducing the pressure in the respective vessel below atmospheric. As shown, vessels 1 and 2 are filled with desiccant, and air to be dried, entering at 3, passes into the vessel 1, dried air leaving at 9. Shortly before the end of a drying cycle, vessel 2 is pressurised, and the air is then diverted to pass therethrough. The air in a wet desiccant in vessel 1 is exhausted to atmosphere through valves 6 and 15; a vacuum pump or ejector 16 then causes valve 15 to close, and the moisture vapour is then exhausted and trapped in a separator 17 or passed to atmosphere until the desiccant in vessel 1 is regenerated ready for the next drying cycle.

Abstract: 959, 024. Flyer spinning apparatus. M. SHINO. Dec. 23,1960, No. 44286/60. Heading D1D. A method of spinning roving or yarn comprises twisting sliver or roving b during passage through a rotating pipe d, causing the sliver or roving by the force of draught air to pass through the pipe from an inlet e coaxial with a bobbin spindle p to an outlet m radially outwardly offset from the axis of the spindle, and winding the roving or yarn emerging from the outlet on to a rotating bobbin n automatically by suction means. Roving or sliver b passes through the front rollers a of a drafting device and is blown downwardly through the pipe d by air blown from a nozzle c. After the roving has passed through the curved and lower portions k, l respectively of the pipe it is caught and wound on to the bobbin n. A suction pipe 25 is provided and a partition 26 separates neighbouring bobbins. The piped is supported at an oblique angle by an arm f having bearings g, is driven by a pulley h from a belt (not shown), and is fixed to a spinning cylinder j. The paper bobbin n is positioned on a spindle p which comprises a shaft 1, Fig. 2, having a conical top 3 which frictionally engages a recess 6 in a shell 5. Bearings 4 allow the shell 5 and hence the bobbin n to rotate relative to the shaft 1 when variations in the thickness and tension of the yarn occur. A shaft 21, Fig. 4, drives the spindle shaft 1 through a conical pulley 12, a belt 13, a conical pulley 11, a pulley 10, a belt 9 and a pulley 2 secured to the shaft 1. The belt 13 is raised and lowered by thread shafts 14,15,the shaft 14 being driven by a rack 20 and a pinion 19. The rack 20 moves transversely in accordance with the up and down motion of a rail (not shown) which imparts copping motion to the spindle n, The arrangement varies the speed of rotation of the shaft 1 so that the yarn is wound at an approximately uniform speed.

In a boiling water reactor in which heavy water is both the coolant and moderator, rapid shut-down in an emergency is effected by the expulsion of part of the moderator by the steam. The reactivity is reduced owing to the replacement of liquid moderator by steam and by the rise of the temperature of the remaining moderator due to heat transfer from the steam condensed by the liquid. The moderator is contained in a calandria tank into which steam may pass from the steam space. In an emergency, a stop valve associated with the calandria is opened and liquid moderator is expelled by steam pressure.

Four lenses 3, 4, 5, 6 are mounted on a rotatable turret 1, e.g. for a television camera. Each lens has an adjustable element (e. g. a diaphragm, or a variable-density filter) which is automatically adjusted to the same value as the lens is swung into the operative position, occupied in the drawing by lens 3. Each lens has a toothed diaphragm-adjusting ring 18, engaging a gear 19 on the same shaft as a pinion 16. Engaging pinion 16 is a toothed sector of a cranked lever 13 pivoted to the turret at 14. The other end of lever 13 carries a follower roller 12. Secured to the front panel 2 of the camera is a guide member 11, whose walls 26 flare outwards at its upper and lower ends. The position of member 11 can be adjusted radially to turret 1 by a rack 9 engaged by a motor-driven pinion 8. As turret 1 rotates to bring a lens into the operative position, roller 12 enters guide 11, and lever 13 is guided by the converging walls . 26 to pivot to a particular position, so causing the diaphragm of that lens to be adjusted to a particular setting. Thus whichever lens is swung into the operative position has its diaphragm automatically set to the same value as the previous` lens diaphragm.

A machine develops vibrations which have a rotational component and a translational component in the direction of the axis of the rotational component. Elastic members interconnect a base 1 and a member 6, such as a part of a screw conveyer, to be vibrated. The arrangement is such as to cause simultaneous resonance in rotation and in translation irrespective of the desired operating frequency. To this end the product of the sum of the reciprocals of the masses of the base 1 and the vibrated member 6, by the linear elastic constant in translation of the elastic interconnecting members, is equal to the product of the sum of the reciprocals of the inertias of the base and the member 6, by the elastic constant in rotation of the interconnecting members. The base is mounted on elastic blocks la and has fixed thereto a tubular member 2, 4 from which is spaced radially a second tubular member 5 carrying the screw 6. Rubber blocks 11 are arranged between the tubular members and similar blocks 12 outside the tubular member 2 are held by outer securing panels 13 bolted through to the member 2. These panels carry unbalanced motors 14, 15 which are adjustable about radial axes to drive the vibrator. Further resilient block devices 19 connected between the members 4 and 5 are arranged at a suitable angle to the vertical axis so as to correspond with the required resonance in rotation and translation. The vibrating part of the apparatus rests on a rubber mounting 8 on the base.
