Abstract: 753,563. Steam cookers. SJOLUND, V. V. Feb. 18, 1952 [Feb. 19, 1951], No. 4296/52. Class 28(1). Several steam cooking chambers 7, 8, 9 for different foods are superposed above a bottom water boiling chamber which is divided into horizontal side by side compartments 1, 2, 3 each of which is connected to a separate pair of steam ducts 13 joined by a top channel 26, each water boiling compartment supplying steam to its own cooking chamber through its own ducts and apertures, the steam passing out and back into the ducts through higher up apertures. Fig. 1 is a sectional front view and Fig. 2 is a sectional side elevation on the line II-II. Steam is supplied by pairs of ducts 10, 11 and 12 from each of the water boilers 1, 2 and 3, the steam being deflected inwards by inclined baffles 16 &c., to pass through holes 20, 21 and 22 into the back of each of the cooking chambers 7, 8, and 9 and escapes into the ducts through upper holes 23 &c. Condensed steam can drain back through a lower hole or slot such as 201 in each of the chambers 7, 8, 9. This condensate along with condensate in the channels 13 flows back through narrow slots 19 into the water chambers, this flow blocking any upward flow of steam into the condensate path. Each water chamber 1, 2, 3 is connected to a common water supply conduit 29. A valve 31 &c., for each chamber is automatically actuated by a float 34 in each chamber to maintain the water level inside. Electric heaters 37 for each water chamber 1 &c. are operated by independent switches 40 which may be adjusted to different temperature ranges for each chamber. Alternatively the water temperatures in each chamber may be controlled by thermostat. To prevent vacuum or excess steam pressure in the conduits, one way valves 41 &c. may be incorporated to prevent vacuum and other one way valves 44 &c. may prevent excess pressure. To prevent an outrush of steam when the door is opened a wire 50 connected to the door handle is arranged to open valves 47, 48, 49 to exhaust any pressure steam in a cooking chamber to atmosphere. Side supports for dishes may be provided in each cooking chamber to allow steam heat to the underside of dishes placed thereon. The sides, back and doors are suitably heat insulated. Dampers may be provided to cut off any of the steam supply to the cooking chambers, to regulate or allow cooking by dry heat only, or to provide a warming box only.

An adjustable socket for an ink roller of a printing press comprises mounting means in the socket body for receiving an end of the roller shaft, a cut-out in the body comprising a track, a plurality of rectangular lugs mounted on the machine frame with at least one of said lugs slidably engaging the edges of said track, an adjusting screw threadingly engaging another of said lugs and passing through a bore in said body with a portion of said screw operatively engaging said body, whereby, as the screw is rotated, the body will be caused to move with respect to the frame, and clamping means independent of said screw for locking the body to the frame when in the clamped position to prevent movement of the body with respect to the frame. A socket body 20, Fig. 2, and cap 21 secured thereto by screws 22, 23 form a receptacle to receive an anti-friction bearing 24 for an ink roller shaft 25. A cut-out 27 in the body 20 slidably receives a lug 28 pivoted to the machine frame, while a lug 30 fixed to the frame threadedly receives a screw 31 rotatable to move the assembly 20, 21, 25 relative to the frame in a direction to move the inking roller equally towards and away from a plate cylinder and an ink drum or two ink drums. A second screw 32 causes the assembly to swing about the pivot of the lug 28, this being permitted by a rotatable insert 33 receiving the screw 31, to compensate for skew or alter the pressure against one of the members in contact with the roller. Clamping screws 41, 42 secure the body in adjusted position to the frame. For unidimensional adjustment, the screw 32 is omitted and the lug 30 is also received in a cutout in the body. A device for adjusting the roller with a predetermined pressure comprises a compression-spring 60, Fig. 6, bearing on a journal 62 and on a spring cover 61 bearing on the head of the screw 31. The force exerted by the spring to urge the roller into operative contact with a drum or cylinder is a function of the length of the spring, which can be read by indicating means and adjusted by rotating the screw 31. The spring may be replaced by a plurality of Belleville washers. In another form for uni-dimensional adjustment, one of the clamping-screws is slidably accommodated in a groove in the body, rotation of the adjusting screw causing the assembly to pivot about the other clamping screw.

Abstract: 806,516. Steam superheaters. COMBUSTION ENGINEERING Inc. Feb. 16, 1955 [Feb. 16, 1954], No. 4646/55. Class 123(3) A superheater disposed in the outlet pass 10 from a boiler furnace 18 consists of five groups I...V of vertical, tubular panels which are spaced across the pass. As shown in Fig. 2, four panels A...D form the group V and are each made up of a pair of nested U-tubes connected to an inlet header 22, the U-tubes forming the panels A, C being connected by respective tubes to the group I panel at the inlet of the pass 10 where the tubes are bent to form a panel E, the pair of tubes from panel A extending down the leading edge of the panel E to its midpoint where they are reversely bent at 26, while the pair of tubes from panel C extend down the trailing edge of the panel E and upwardly along the leading edge to the midpoint where they are reversely bent as shown at 28. From the respective reverse bends the tube pairs are bent in a serpentine manner to form the remainder of the panel E, the two pairs of tubes then being led rearwardly to the location of the group III panel where they are bent as for the panel E to form a panel F, the final limbs of this panel connecting to an outlet header 24. The pairs of tubes forming panels B, D extend upstream through the pass 10 to the location of the group IV panels where they are bent to form panels B<SP>1</SP>, D<SP>1</SP> respectively, after which they combine to form panels G, H in the groups II, III respectively, the panels G, H both being formed in the same way as for the panel E. The final limbs of the panel H are connected to the header 24. The panels of groups I and II are widely spaced to prevent slag bridging whilst the reverse bending of the two pairs of tubes to form the leading edges of panels E...H which are exposed to furnace radiation and impingement of high temperature gas provides a doubled steam flow in these panel edges, thus reducing metal temperature in this region and prolonging tube life. In the complete installation, sufficient interconnected panel arrangements as shown in Fig. 2 are provided to extend wholly across the gas pass 10. Specification 806,517 is referred to.
