Title: Improvements in fire escapes
IPC: E06C9/08
Filed: 1949-09-20
Abstract: 685,632. Fire-escape ladders. BERNER, C. A. O. Sept. 6, 1950 [Sept. 20, 1949], No. 24193/49. Class 20(ii) A telescopic fire escape ladder A, B, C, when inoperative, is nested on a carrier 2 and its movement to operative position is controlled by radius rods 5 connected to the top (in the operative position) ladder section A at one end and guided in horizontal slots 73 in the carrier at the other end. In operation, a shaft i, on which the section A is freely mounted, is driven by an electric motor or by hand and drives, by means of a sprocket, a chain 23 connected to both ends of the ladder and the ladder and radius rods move horizontally until slots in the ends of the latter engage a rod 6, about which the rods 5 pivot and the ladder tilts and moves outwardly and downwardly from the building into the operative position. The rods 5 move in slots in the floor of the carrier 2 adapted to be covered by plates 7 moved into position by hinge connections 8 to the rods 5. When the ladder moves to inoperative position the plates 7 move from a rod 11 and dip under the floor of the carrier. The ladder sections are provided with speedgoverning devices 30 driven by chains 31 connected to the ends of the ladder sections, the devices 30 having free wheel sprockets to allow the ladder to be raised. The upper and lower ladder sections may be connected by chains 40, 44, Fig. 6, passing over sprockets 42 on the ends of the middle sections. The carrier 2 may be mounted on wheels 3 or fixed in position. The top section may carry a tripping mechanism to release the second section after predetermined travel of the top section. Specification 664,632 is referred to.

Title: Improvements in, or relating to lawn mowing machines
IPC: A01D34/54
Filed: 1923-10-01
Abstract: 219,210. Hadley, I. A. Oct. 1, 1923. Lawn-mowers. -- To adjust the height of cut the rear roller e is mounted in brackets g having inclined forward portions h provided with rectilinear inclined slots i through which the clamping screws n. for the brackets pass. Each bracket is adapted to move along a slight channel in the side plate parallel to the axis of the slot j. Adjusting the height of the roller to give a closer cut simultaneously lengthens the wheel base of the machine and so minimizes the tendency of the machine to lift. In a modification the roller is mounted in a vertical bracket which is secured at each side bv a clamping screw passing through an inclined slot in a rearwardly extending portion of the frame. In each form the adjustment along the slot may be accomplished by rack and pinion gearing.

Title: Improvements relating to space heater appliances
Inventor: RAVENSCROFT GREVILLE SANDFORD
IPC: F24F3/12
Filed: 1963-06-21
Abstract: 1,026,966. Space heater incorporating air conditioning. ENGLISH ROSE KITCHENS Ltd. May 19, 1964 [June 21, 1963], No. 24681/63. Heading F4V. A space heater, heated by electric or gas-fired heating elements 3, includes air conditioning means wherein a convection current of heated air draws off vapour from a liquid vaporizer comprising upwardly directed tubes 14 in which a static liquid level is maintained, the tubes being open at their upper end for the discharge of vapour therefrom into the path of the heated air. In the form shown, a heated convection air duct 6 is provided between a metal casing 2, and a metallic reflector 4 which becomes heated by close contact with the heating elements 3. The duct may be divided into two sections by a vertical partition 8, Fig. 2 (not shown). The vaporizer tubes 14, preferably of rectangular cross-section, are brazed or otherwise fixed to the reflector 4. Heat from the reflector vaporizes the liquid in the tubes and the vapour is sucked through the discharge openings 15 into the convection current due to a low air pressure region around the openings brought about by a narrowing 9 in the air duct. Liquid in the tubes is kept at a static level by a constant head device 12, Fig. 4, which is fed via inlet 22 from a reservoir 10. Outlet 19 supplies liquid to the vaporizers and the constant head is maintained by an air conduit 27, terminating in a flared open end 28 which replaces liquid lost from the reservoir by air until the liquid level in the device reaches end 28 so that further flow of the liquid ceases. The level of the liquid may be varied by moving the constant head device up or down in a metal slideway 31 by a control 33. To accommodate this movement the associated conduits are made of flexible tubing provided with a drain plug 36.

A throttle member 30, disposed coaxially within the top section 12 of a chimney 10 to define therewith an annular gas exit passage, is designed to vary automatically the crosssectional area of the gas exit passage in accordance with variations in the rate of flow of gases entering the chimney from a furnace so as to maintain the exit speed of the gases issuing from the top of the chimney substantially constant. The throttle member 30 has an axial passageway 29 slidably mounted on a tube 2 1 which is secured to the chimney by a spider 20. Vertical movement of the member 30 is effected via a piston-rod 27 which is connected to an hydraulic cylinder 23 housed within the tube 21 and supplied with fluid through feed lines 25 (26, Fig. 2). In operation the vertical position of the throttle member 30 and thus the gas exit cross-section is automatically adjusted according to the furnace burner setting, the member 30 being in its lowest position (dash-dotted line) for a maximum burner setting and in its highest position (as shown) closing the gas exit when the burner is shut off. In an alternative embodiment shown in Fig. 3 the throttle member 50 comprises an inverted frusto cone, its operation being the same as de3cribed above.

Abstract: 205,301. Weyman, G. Sept. 14, 1922. Packing and filling ammonium sulphate into sacks.-Ammonium sulphate which may be neutralized in the centrifuge, as described in Specification 183,089, is fed from the centrifuge by a conveyer c from which it falls upon a pivoted' screen or sieve d, which is mechanically agitated by a chain e, lever f, and arms g carried on the upper sprocket of the conveyer, and then falls in a shower h on to a distributing arrangement consisting of grids or hurdles k, l leaning against one another to form a ridge (as shown) or to form a pyramid or cone. The salt is made to fall mainly on one side of the grids until a heap n has formed, and is then diverted in any manner, for instance by moving the conveyer, or by screens, so as to fall upon the othar side to form a heap m. After a short time the salt is removed from the heap n by being allowed to fall through a valve q into sacks. Similarly the heap m is withdrawn at r and a heap o, which forms between the grids, is withdrawn at s. Two or more sets of grids may be employed, the shower of salt being diverted to each in rotation, and the floor on which the heaps rest may be movable for instance as a platform on rails. When the salt is to be in large heaps an arrangement of grids is built up as shown in Figs. 2 and 3, the hurdle grids t being supported by cross-pieces u, v.
