Title: Improvements in and relating to heating systems employing a circulating heating medium
IPC: F24D3/10
Filed: 1933-10-19
Abstract: 427,481. Valves. FARRER, J. 0., 27, Chancery Lane, and KOCH, E. A. J., 64, Victoria Street, both in London. Oct. 19, 1933, No. 28969. [Class 135] [See also Group XIII] Valves are actuated by floats through mechanism which only operates the valve when the speed of movement of the float exceeds a fixed limit. In one construction a float 9 in a liquid containing vessel 1 is connected to a piston 14 working in a cylinder 15 having a byepass 16. When the speed of fall of the float exceeds .a fixed value the bycpass proves insufficient to equalize pressure on both sides of the piston and the cylinder is raised operating valve 20 which admits fluid above a piston 22 and closes the valve 4. The float may alternatively release a weight 54 through a hydraulic transmission comprising pistons and cylinders 47 and 48 with an adjustable leak in their connecting pipe, the weight operating valve 4. In an alternative construction the float may be attached to a sector 57 meshing with gearing 60, 61, and 62. The whcel 62 is provided with a ratchet drive 63 preventing it exceeding the speed of the constant speed motor 64. Thus when the movement of sector 57 exceeds a fixed rate the wheel 60 is forced to swing on its link 59 and operate control means through a rod 66. Specification 413,667, [Group XIII], is referred to.

Abstract: 745,188. Extruding. SCHLOEMANN AKT.- GES. Oct. 21, 1953, No. 29040/53. Class 83 (4). An extrusion press, for producing conical and similar articles whose cross-section varies along the length thereof, has an extrusion ram 22, Fig. 1, operated by pressure fluid under the control of a throttle valve 43, and an extrusion die formed by a number of slidable die parts 15, Fig. 2, which are moved during extrusion for varying the die opening by a driving mechanism which also controls the throttle valve 43 so that the speed of extrusion is dependent upon the die opening. The die parts 15 are actuated by spindles 16 carrying bevel gears which are all connected together, so as to operate the die parts in unison, by intermediate bevel gears 17. Two of the spindles 16 are driven by motors 20, and another spindle 16 is connected through a spindle 21, bevel gear 4, gearbox 6 and bevel gears 7 with the throttle valve 43. The press may be used for solid bars or tubes. In the latter case a conical mandrel which moves longitudinally during extrusion, is employed.

Abstract: 1402374 Feeding and delivering sheets BURROUGHS CORP 19 June 1973 [3 July 1972] 29095/73 Heading B8R A unitary feeding and stacking attachment for an accounting or other sheet-handling machine comprises a supply hopper 41, Fig. 1, from which documents piled on edge are fed one by one by rollers on shafts 121, 125 along guides 47 to and through the throat 37 of the machine, and after processing are passed along guides 49 and by rollers on shafts 151, 149 into a receptacle 43. Alternatively, a document is delivered to a hold station at the level of the shafts 151, 149, returned to the machine for further processing, and then delivered to the receptacle. In response to signals from the machine, a reversible motor 87 is driven in one direction while a clutch control solenoid 106, Fig. 3, is energized, to feed a document from the hopper, in the opposite direction for a shorter or longer time to deliver a document to the hold station or to the receptacle, and in the first direction without energization of the solenoid to return a document from the hold station to the machine. The hopper and receptacle are formed of wire-like members and divided by a pivoted divider 45 which moves counter-clockwise as documents are fed from the hopper and to the receptacle to enlarge the latter while diminishing the former. To accommodate documents of different widths, an adjustable end plate is provided, being inserted into selected grooves in lateral support shafts 59, 63, 69. To prevent double feed, the lower feed rollers co-operate with adjustable scrub rollers 138 defining a gap sufficient for one document, the rollers 137 rotating so as to urge a second document upwards.

[Classes 20 (i), 20 (ii) and 20 (iv).] The invention of the parent Specification is modified to comprise the use of structural members the lengths of which differ in amounts which are equal to or are integral multiples of the sectional dimensions of the members disposed at rightangles to these structural members plus a constant which equals the sectional dimensions less a predetermined spacing distance at the ends of each element. By using such constructional units, the girders are spaced from the columns at their ends by standard amounts, and may be supported on brackets B, Fig. 2, or may be interlocked with the columns at 32, 33, Fig. 4. This spacing may be filled with concrete in the finished structure. A form of wall constructed with these structural members comprises flanged pillars P<1> with supporting brackets 67 for the girders 74 and cradles 85 attached to the girders for supporting the intermediate members 86. The girders are formed hollow and comprise side members 74 with perforated upper and lower plates 72, the perforations being spaced according to the module employed for the lengths of the structural members. The intermediate posts are formed hollow of perforated channel sections 96 and endplates 98, the apertures 109 in the endplates registering with the apertures 80 in the upper plates of the girders, so that poured concrete may pass through the girders to the posts and form filling portions 104 for the wall slabs 100, wooden filling pieces 114 restraining the concrete within the posts. Downturned lugs 69 on the ends of the girders serve to connect them with the posts.
