Title: Improved construction of machine frameworks
IPC: B30B15/04
Filed: 1942-07-23
Abstract: 560,229. Machine frames; hydraulic presses. HYDRAULIC ENGINEERING CO., Ltd., and MANGNALL, A. R. July 23, 1942, Nos. 10311/42 and 2078/43. [Class 80 (iv)] [Also in Group XXIX] A laminated machine framework comprises a cross frame part connected between a pair of laterally spaced column parts, wherein each such part is composed of a plurality of plate elements connected together by connecting means which, when a bending stress is applied to the cross frame permits the plates of the latter to move relatively to the plates of the column parts in the direction of the applied stress so that this stress may be converted wholly into tensile stress in the plates of the column parts exerted in the direction of the length thereof. As applied to a press, the framework, which comprises a base 1, a head 2 and vertical columns 3, Fig. 1, is built up from a number of flat plates generally of steel assembled and secured together by transverse screw-threaded rods 4 furnished with nuts to form a laminated structure to or from which parts can be added or removed at will. The plates 5, 6, Fig. 3, of the'head and base alternate with the plates 8 of the columns which may be single vertical plates or opposite pairs of such plates joined together at their top and bottom ends. Each column plate 8 has apertures 9, Fig. 4, near its ends which correspond with apertures 7 in the plates 5, 6. Bushes or collars 10 fit the rods 4 closely and are somewhat thicker than the plates. The plates 5 in the head may have cantilever extensions which may serve to enclose horizontal side rams. The holes 9, 7 are larger respectively than the rods 4 and collars 10 and bearing strips 7b, 9b are inserted in the clearances after which all play is taken up by a wedge action as in Fig. 5. The plates 8 have lateral lugs 13 with a tongue portion 13a engaging a recess in a stretcher block 14, 14a adapted to bear on a head plate 5 or base plate 6. A conical plug 16 forced into a taper socket 15 exerts the necessary stretching force. A press of the down stroke type with a laminated frame made as described above is shown in Fig. 13. The frame serves to guide a box 29 housing the conventional rubber pad 30, the box being moved up and down by side rams 33 to bring it towards or away from a table 34 the pressing operation being performed by overhead cylinder 31 and ram 32. The plates of the laminated box may pass through the spaces between the plates of the columns. Units of pre-assembled plates may be used. The spaces between the plates may accommodate guides for the press table, or parts of the mechanism of the machine, e.g. hydraulic pipes. The transverse plates are preferably so constructed as to . provide compensation for unequal expansion of the base and head plates due to temperature changes. They may be divided into parts 18, 18a, Fig. 8, and connected by links 20 or, in a modification, by a strip of spring steel. In a further modification, Fig. 12, the inner end of one section of plate 25 may have a knob 26 adapted to enter a slot 27 in the other plate section 28.

Abstract: 514,243. Making mineral wool. DEUTSCHE EISENWERKE AKT.-GES. April 3, 1939, Nos. 10324 and 10325. Convention dates, April 16, 1938, and July 30, 1938. [Class 56] Relates to the production of mineral wool by the blast process and consists in using a flame as the blast jet, which shreds the molten material, in order to prevent excessive chilling of the material. The flame may be produced by the combustion of compressed coke oven gas, acetylene, or other suitable gas. Alternatively, uncompressed combustible gas may be fed into a jet of compressed air which has been preheated to 600-800' C. The gas may be fed into the air jet either before or after the air meets the molten material, the position being regulated according to the position desired for the zone of highest temperature. Instead of a flame, gas which has been preheated to a temperature above 800-1,000‹ C. may be used. The air that carries the fibres away from the jet may also be heated to anneal the fibres.

Filed: 1941-08-14
Abstract: 546,607. Air conditioning apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 14, 1941, No. 10340. Convention date, Aug. 14, 1940. [Class 137] [Also in Group XIII] A portable air-cooling unit for rooms comprises a casing 10 having an outlet 35 for discharging the cooled air into the room and a second outlet 15 for discharging air to the outside, and two inlets, one between the casing and a cover 11 for room air and one 14 for fresh air. Air passages within the casing provide circulating paths from the inlets to the outlets under control of a single damper 43 so that either fresh or room air may be cooled by passage through an evaporator 30, forming part of a refrigerating machine, before admission to the room, the room air or fresh air being passed to the outlet 15. The casing is divided into compartments by a partition 19, the compartment below the partition containing a compressor 21 driven by a motor 20, and three fans 23, 24, 25 driven by a motor 27. The compartment above the partition houses an evaporator 30 for cooling the air, and a condenser 31 separated by a partition 29. Air from fan discharge outlets 32, 34 is delivered into the rear compartment, and that from outlet 33 to the front compartment and through the cooler 30 and a grille 35 into the room. A rectangular chamber 37 communicates by openings 38, 39 with fan casings 24, 25, the front end opening into the cabinet and receiving the room air, while the rear end receives fresh air. With the single damper 43 in the position shown in full lines in Fig. 2 the fan 41 draws in fresh air and the fan 42 room air, and in the position shown in dotted lines, fans 41 and 42 draw in room air and fresh air respectively; an intermediate position of the damper causing a mixture to be delivered to both fans. Vertical louvres 47, 48 ensure that a small proportion of fresh air will enter the room through the fan 41 with the damper as shown in dotted lines, but these louvres offer more resistance to the air flow with the damper as shown in full lines. Moisture condensed on the evaporator 30 runs down the partition 19, collects at its lower end, is vaporized by heat from warm refrigerant liquid in a receiver 54, and is carried away by the stream of air to the outlet 15. Excess water drips on to the blades of fans 40 and 42 and is dissipated. Fan 40 draws in fresh air through opening 36, this air circulating around the refrigeration plant and being discharged to outlet 15, carrying away fumes from the plant.
