Title: Improvements in or relating to apparatus for perfuming or sterilising the atmospheres of rooms and like enclosed spaces
IPC: A61L9/12
Filed: 1935-10-22
Abstract: 464,850. Holders for vaporizable materials. WALKER, Ltd., W. & F., and FREESTONE, J. T. Oct. 22, 1935, No. 29072. [Class 81 (i)] A holder for volatizable material, such as ammonium carbonate or impregnated absorbent material, comprises an exterior member or cap 10, Fig. 1, moulded from synthetic resin, and an interior perforated container 11 which is a frictional sliding fit in the cap 10, so that the parts may be adjusted to vary the rate of evaporation, and is adapted by means of a slightly coned part 14 and a flange 14a to make a gas-tight connection with the cap 10 when closed. A cartridge, Fig. 2, for use in the container 11 comprises flanged end caps 16 holding an ammonium carbonate block 18 mounted on a conical spool 19 and surrounded by a tubular coil 17 of blotting paper impregnated with oil of lavender. In a modification for pocket or like use the perforated container or cage 33 telescopes within a cap 32 and is provided at its base with metal lugs 38a which, on assembly, spring over an internal flange 35 on the cap 32, but present complete separation of the parts. A cap or stopper 40 has a threaded portion 41 engaging the cage 33 and a threaded portion 42 engaging the cap 32. The cage contains a roll 44 of impregnated blotting paper enclosing tablets 45 of compressed ammonium carbonate, or may contain either alone. According to the Provisional Specification the inner perforated member may consist of a wire mesh screen mounted on a plinth and having, at its upper part, an outwardly turned springy lip or lugs to co-operate with notches on the outer member to hold the parts in adjusted position. The lugs may be barb-shaped to co-operate with a barb-shaped lip on the outer casing to prevent complete separation of the parts. The outer casing may have a sliding cover plate or screw cap to permit recharging an impregnated tightly compacted roll of impregnated blotting paper contained in the inner perforated member. In a modification the outer member has a spring pressed catch to engage the perforations of the inner member. The outer member, or the base of the inner member, may have lugs whereby the appliance may be secured to a wall.

Abstract: 700,655. Refrigerating. BRITISH THOMSON-HOUSTON CO., Ltd, Dec. 12, 1951 [Dec. 21, 1950], No. 29105/51. Addition to 688,190. Class 29 A frost indicator for domestic refrigerators shown in plan in Fig. 2 comprises a spring- pressed sliding feeler bar 7, similar to the feeler bar of the parent Specification but twisted into a spiral at 34 to rotate an indicating disc 51 with a pointer 50 showing the amount of frost. The evaporator 4 extends across the full width of the food chamber and is closed by a door 5 on horizontal bottom hinges biased to the closed position by a spring 38 acting on an arm 39. When the door 5 is closed an abutment 47 on the arm 39 engages a depending member 48 on the slide 7 and moves the slide rearwardly against the action of a spring 35 so that the frostengaging portion 10a is spaced from the frost on the evaporator. On opening the door 5 the abutment 47 moves forward allowing the spring 35 to move the slide 7 forward a distance depending on the thickness of the frost on the rear wall of the evaporator. The spiral portion 34 of the slide engages an elongated slot in the end cap 25 of a tubular member 17 rotatably mounted in a bracket 18 and carrying at its front end the indicating disc 51 visible through an aperture in a filler strip 52. The sides of the slot in the end cap 25 are rounded to prevent binding of the spiral 34.

Abstract: 1,019,705. Winding armatures. G. A. RIX. July 22, 1964 [July 26, 1963], No. 29683/63. Heading B3A. In a method of winding armatures an armature core 4 is given a linear motion through the guide means or head stock, so that the wires 12 are laid in the core slots, until the core has passed the wire inlet region. The core 4 is rotated and given a reverse linear motion, the process continuing until the production of the required number of windings, whereupon the wires are severed. For the initial stroke through the headstock a location ring 23 is fitted to guide the wires into a gripping collar 21, which has a sleeve 24 to align the ring 23 with the armature slots. After the initial stroke the ring 23 is replaced by a collar 22. When the winding process is completed, the armature is withdrawn from the headstock and a core is mounted on the opposite side thereof. The new core is moved into the headstock, the ring 23 picks up the severed ends of the wires and the winding process continues as before.

Title: A new or improved coin insertion prepayment mechanism
IPC: G07F15/02
Filed: 1951-12-24
Abstract: 733,156. Prepayment meters. METROPOLITAN GAS METERS, Ltd., and HARRISON, S. Oct. 31, 1952 [Dec. 24, 1951], No. 30104/51. Class 27. A prepayment mechanism for gas, electric, water and other meters and operable by a selected coin of two different diameters has a single coin slot 1 and detector means 14 for detecting the insertion of a coin of intermediate diameter and preventing operation of the mechanism consequent upon such insertion. A pair of interlocking pressings 9, 10 are secured to the rear of a disc 4 rotatable on a disc 2 adjustably fixed on the meter housing by serrations 3 and between them, in register with the coin slot, a plate 21 is slidable against the action of a spring 26 and is connected by a pin 23 to a striker 25 projecting through a slot 27 in the pressing 10. The spring-loaded detector lever 14 is pivoted at 15 and has a roller 13 projecting across the coin pocket between the pressings 9, 10 and a lug 19 projecting through a slot 20 into a slot 22 in the plate 21, the slot 22 being formed with recesses 31, 32. If a sixpence is inserted, it clears the roller 13 but depresses the plate 21 until the lug 19 engages the top of the recess 31, so setting the striker 25 to engage a quantity wheel corresponding to the value of sixpence. If a shilling is inserted, it depresses the roller 13 and pivots the lever 14 so that the projection 19 moves into the longer recess 32, thus allowing a greater movement of the plate 21 and setting the striker to engage a further quantity wheel corresponding to the value of a shilling. If a coin of a diameter intermediate a sixpence and a shilling is inserted, as shown in Fig. 4., the projection 19 engages below the leg 33 between the recesses thus preventing depression of the plate 21 and full insertion of the coin. The mechanism is rotated to set the selected quantity wheel by a shaft 6 having a projection 7 that engages the side of pressing 10 and a lug 34 and projection 30 limit the return rotation of the mechanism. As a further safeguard, the shaft 6 may have a leaf fitted between the discs 2, 4 so as to engage a coin that has not been fully inserted and thus prevent rotation of the mechanism. In a modification, Fig. 6, the lever 14 has a detector lug 44 and a hook-shaped end and the pin 23 on the plate 21 projects through a slot 40 in the pressing 9. Coins of the prescribed diameters either set the lever 14 so that the recess is below the pin 23 or move the lever clear of the pin and coins of intermediate diameter bring a projection 43 below the pin to prevent depression of the plate 21. Specification 704,477 is referred to.

Title: Improvements in or relating to ferrous alloys and methods of making same
IPC: C21D8/00
Filed: 1934-01-01
Abstract: In a method of making ferrous alloy articles as described in the parent Specification, the articles after heating to a temperature above the critical point are cooled from that temperature and then subjected to further heat treatment to harden the surface of the articles.  The heat treatment involves heating to temperatures from 900-1800 DEG  F., and quenching, and may be applied to a selected part or selected parts of the article.  The alloy may contain 1,5-2,5 per cent of carbon and 0,6-0,9 of silicon, but if the alloy contains 1,5-2,0 per cent of carbon and up to 1 per cent of manganese the silicon content may be increased to 1,3 per cent.  The alloy may also contain 0,75-2,0 per cent of nickel, 0,2-0,5 of molybdenum, 0,5-15,0 of aluminium, 0,5-18,0 of chromium and tungsten and up to 1 of vanadium.  The Specification as open to inspection under Sect. 91 states that the process described in the parent Specification may be applied to ferrous alloys containing molybdenum with or without nickel or silicon.  This subject-matter does not appear in the Specification as accepted.
