Abstract: 554,517. Storage cabinets. FAULKLES, T. E., and CO-OPERATIVE WHOLESALE SOCIETY, Ltd. Feb. 12,1942, No. 1880. [Class 52 (1)] A storage arrangement comprises containers mounted in rows for relative lateral movement the containers having their front access faces all in same direction and the containers in one row mating by stepped or inclined face with those of an adjacent row, the depth, length and height of the storage supports in the containers or the containers themselves being graded so as to provide storage spaces of different proportions. Fig. 2 shows a fixed row 10 of containers and a sliding row 13 the contiguous faces being stepped. Shelving is provided which is graded in depth and vertical divisions may also be provided so that the storage space may be economically utilised by articles of different sizes and the arrangement is such that the articles stowed within normal reach i.e., within the height defined by the lines A, B, are duplicated by those stowed in the heights above and below such height. To obtain access to the fixed row of containers the front row 13 are slid laterally. Figs. 4 and 7 indicate examples of arrangements in which the back row is fixed and the other rows are movable laterally, the various or graded depths of the shelving being indicated by dotted lines. Fig. 12 shows an arrangement in which the units 53- 59 in a row are graded as to length, a space length 60 equal to the length of the longest unit being provided whereby the units may be moved laterally to expose one or more units in an adjacent rear row. In another arrangement the units may be superposed the open access faces being at the top, somewhat resembling the units shown in Figs. 4, and 7 laid on their backs. Specification 470,516 is referred to.

Title: Process for the production of easily filterable magnesia and ammonium-magnesium-double salt
IPC: C01F5/20
Filed: 1950-01-25
Abstract: Magnesia is prepared from a solution containing a magnesium and ammonium salt, e.g. the sulphates, representing a mother lye recycling from the process, by simultaneously introducing the solution and gaseous ammonia, the latter in twice the theoretical amount, with continual stirring, into another part of the lye, whereby precipitation of magnesium hydroxide occurs above 50 DEG C, e.g. 60-80 DEG C, up to a concentration of over 15 per cent ammonium salt, filtering off the magnesium hydroxide, expelling excess ammonia by heat or vacuum, adding to the solution solid magnesium salt the same as that present therein to form an ammonium magnesium double salt, filtering and recycling the mother lye. In a modification, instead of adding solid magnesium salt, the ammonium magnesium double salt is recovered by evaporation, and the liquor is then enriched with magnesium salt.

Title: Improvements in electric flat irons
IPC: H05B1/02
Filed: 1923-01-23
Abstract: 213,712. Hoofnagle, W. T. Jan. 23, 1923. Electric hand-irons.-The iron consisting of a sole-plate a containing the heating resistance and covered by a handled-top b made of heat insulating material such as asbestos composition is provided with a hollow plug containing an accessible fuse and an inaccessible fuse of different melting points and with a filament visible through the top of the plug to indicate when current is flowing. The plug comprises an insulating body externally screw-threaded and metal-sheathed to contact with a fixed threaded metal sleeve 17 in electrical connection by a plate 17<a> with one terminal of the iron. A circular hole 24 in the plug slidably receives the shank 32<a> of a metal head 32 prevented from rotating by a square ring 32<b> received in a square continuation of the central hole of the plug. A metal ring 26 secured in place and connected to another metal ring 27 by bolts 28 surrounds a boss 25 on the plug and forms, with head 32, a clamp to hold the fusible strip 33. When the plug is screwed down the head engages a contact plate d in electrical connection with the other terminal of the iron. The head 32 is grooved and the plate d is dished to catch any fused metal. The ring 27 and sheath 18 are connected by a filament 31 visible through the transparent cover 20 and by a fuse wire 30 which by reason of its location is not accessible and serves as a further safety fuse. Spare fuses 13 are kept in a recess in the top covered by a metal plate 14.

Abstract: 620,627. Cooling resistances. SUNBEAM COMMERCIAL VEHICLES, Ltd., and DABBS, J.C. Jan. 24, 1947, No. 2210. [Class 37] [Also in Group XXXI] The banks of resistances used in controlling the current in acceleration and deceleration of an electrically-driven vehicle are enclosed completely within a duct having an opening at each end in the direction of running in order that a current of air may be directed along the duct, thereby assisting in the cooling of the resistances and preventing access of foreigh matter to them. The end of the duct in the direction of running is preferably sloped downward toward the opening. As applied to a vehicle for unidirectional travel, such as a trolley bus, the banks of resistances 10, Fig. 1, are longitudinally spaced in the vehicle and enclosed in a duct 14 having a rectangular cross-section. The base of the duct 14 is sloped upward to pass over the wheel axle 15 and then has a downwardly sloped portion to the end 12 of the duct. This end 12 is immediately behind the front portion of the bodywork, having an aperture 17 over which is fitted a grill 18. Air passes through the grill 18 along the duct 14, cooling the resistances, and' is exhausted at 13. If the vehicle is adapted to drive in two directions, the opening 13 may be replaced by a similar arrangement to that shown at the front. According to the Provisional Specification, baffles may be fitted in the duct.

Class 126 A draught regulator for use with an open fireplace comprises a carrier plate adapted to be fixed across the upper part of the open front of the fire space, and carrying a horizontal baffle on which a slidable damper is mounted for co-operation with the upper part of the fireplace back to control the size of the chimney throat. The carrier panel 1, which has a bowed portion 4 forming a canopy across the upper part of the fire space, is removably secured to the front of the fireplace by screws and clamping nuts 3. A baffle plate 5, extending nearly the full width of the fire space and halfway towards the fire back 6 is spaced from the carrier plate 1 by a slot 8, the width of which can be varied by adjusting screws 13. A sliding damper 17, controlled by push-pull rod 18, moves in guides 16 and carries pins 20, Fig. 5, which move in slots 11 formed in the fixed baffle 5 to clear them of soot. An inverted trough 9 mounted on the underside of the fixed baffle 5 has slots registering with the slots 11 in 'the baffle plate. Clearances 21 are provided at the side of the baffle to allow an additional escape path for smoke when the damper is closed. In a fireplace with a back boiler, Fig. 9, the inspection plate 24 closing the front of the boiler flue 22 is forwardly inclined at its upper end to form an outlet 25 with its top edge level with the top of the fixed baffle 5. The sliding damper 17 can be partly closed so that the draught all passes round the boiler flue or adjusted so as to close the boiler flue, or to regulate the draught through the main fire space while leaving the boiler flue open. According to the second Provisional Specification the boiler flue may be made open to the fire space immediately above the boiler, the up-draught passage associated with it being closed by a substantially horizontal plate, and the open end of the flue above the boiler having a hit-and-miss damper mounted on the inspection plate and operated from the front of the inspection plate. In addition, a raised horizontal grill may be provided, forming the floor of the flue beneath the boiler, together with a rear vertical grill.

Filed: 1955-01-27
Abstract: A cable conductor is enclosed in a laminated body built up from insulating strips and permeated with a gel formed by subjecting a liquid organo polysiloxane to high energy irradiation.  When the cable is irradiated before sheathing, the impregnant used has a viscosity such that it will be retained in the laminated body until it has been gelled.  Alternatively, a temporary or permanent sheath of a kind which does not absorb sufficient radiation to form an effective screen may be applied directly after impregnation. Preferably one or more electron accelerators are used as the radiation source, the beam of high speed electrons having a speed equivalent to not less than IMeV. Alternatively, the radiation may be produced in a nuclear reactor and have an intensity of not less than 1014 thermal neutrons/sq. cm./min., or from X-rays or radio-active isotopes giving a radiation of not less than 1,000 Roentgens/min. Specification 182,510 [Class 36] is referred to.
