Title: Improvements relating to signalling lamps
IPC: F21V17/02
Filed: 1941-10-22
Abstract: 553,537. Signalling by visible signals. ALDIS BROS., Ltd., and ALDIS, A. C. W. Oct. 22, 1941, No. 13555. [Class 118 (ii)] A signalling lamp for emitting flashes of different colours consists of a number of louvrelike screens adapted to transmit light of different colours and arranged one behind another, and means for actuating the screens. The screens e are contained in a rectangular casing d which is attached to a signalling lamp a and is provided with a handle 15. Each screen consists of a number of slats n of translucent material pivoted at their ends to a frame o, and connected to one another by a link s which is movable vertically to turn the slats from a vertical to a horizontal position. Each link is pivoted at its lower end to a crank u on a shaft t to which toothed segments z are secured. Each screen gives a different colour to the beam of light emitted by the lamp, and a separate opaque screen may be provided for occulting the light between flashes. The screens are operated by rods x each of which is movable longitudinally against the pressure of a spring 3 housed in a bush 2 supported by the casing. Three gapped racks y are secured on each rod, and the bush 2 can be turned to different positions of adjustment to turn the rod and bring a particular rack into engagement with a segment of a particular screen, so that the screen can be operated by sliding the rod. Another rod 8, which can be moved longitudinally against the pressure of a spring 10 by a trigger 16, is provided with an arm 9 for moving the rods x. Another arm 11 in the rod 8 carries a spring-loaded pawl 13 which engages a cylindrical gate 14 composed of parallel strips 18, 19, Fig. 6. In use, the rod 8 is turned through an angle by an arm 21 against the pull of a spring 12, the pawl 13 riding over the strips 18, 19. When the trigger 16 is pulled, the rod 18 is moved inwards and the screens e are operated. At the end of the inwards movement, the pawl 13 passes from a strip 18 into contact with a strip 19, and at the end of the reverse movement it passes into contact with the next strip 18. Thus, with successive pulls of the trigger, the rod 8 is turned backwards to its initial position in a succession of steps, and the arm 9 moves the rods x in succession. The coloured flashes are emitted in a sequence determined by the adjusted positions of the bushes 2. In a modified arrangement, the screens are actuated by separate racks, the signalman manipulating the racks in appropriate sequence.

Abstract: 1,248,122. Tri-aryl lead halides. INTERNATIONAL LEAD ZINC RESEARCH ORGANISATION Inc. 14 March, 1969 [15 March. 1968], No. 13572/69. Heading C2J. Tri-aryl lead halides of the general formula wherein the radicals Ar are substituted or unsubstituted aryl radicals and X is chlorine, bromine or iodine, are prepared by reacting a hexa-aryl di-lead compound of the formula Ar 6 Pb 2  with a hypohalous acid. The aryl groups may contain up to 12 carbon atoms and may be substituted by halogen atoms or nitro or alkoxy groups. The hypohalous acid is preferably formed in situ by reacting a hydrogen halide and an alkali or alkaline earth metal hypohalite at a pH of not less than 4. The medium for carrying out the reaction is either a homogeneous or a non-homogeneous system of solvents, both the hexa-aryl di-lead compound and the hypohalite salt being soluble in at least one component in the case of a non-homogeneous system. The reaction is carried out by adding a hydrogen halide or an aqueous solution thereof to a mixture of the hexa-aryl di-lead salt compound and a slight stoichiometric excess of hypohalite salt in the medium until the whole of the hexa-aryl di-lead compound has reacted.

Title: Improvements in gearing for converting rotary motion into variable reciprocating or variable oscillating motion
IPC: F16H25/00
Filed: 1945-06-05
Abstract: 592,993. Cam gearing. MELDRUMS, Ltd., and WRIGHT, A. N. June 5, 1945, Nos. 14083/45 and 3550/46. [Class 80(iii)] [Also in Groups XXX and XXXVI Cam and follower gearing for converting rotary into a variable stroke reciprocating or oscillating motion is described in relation to an underfeed stoker for feeding solid fuel to a furnace. A main driving motor drives a shaft 31 and a feed screw 18 through worm and wheel gearing 36, 35 and fuel is supplied from a hopper 22 to the screw 18 by means of a reciprocating feed tray 24. The reciprocating motion of the tray 24 is derived from a lever 54 which is oscillated by the engagement of a follower 48 in an endless cam groove 46 on the shaft 31. This cam groove is formed by two sleeves 42, 43, the sleeve 42 being fixed to the shaft by a cross-pin 44 and the sleeve 43 being axially adjustable on a key 45 so as to vary the width of the groove to introduce lostmotion into the drive whereby the stroke of the reciprocating tray 24 is varied which thus varies the rate of feed of the fuel from the hopper. The delivery end of the tray 24 is formed with spaced fingers 28 which prevent the passage of larger lumps of the fuel to the screw 18 and deliver them to a chute 29. The axial adjustment of the sleeve 43 is effected by means of a guide member 57 with a flat surface 59 and side flanges 60, Fig. 4, which allows free rotation of the sleeve 43 and is adjustable axially of the shaft 31 by means of an eccentric 65 and a sheave 61 engaging between the flanges 60. The adjustment of the eccentric thus varies the rate of feed of the fuel to the furnace and this adjustment may be effected automatically according to conditions associated with the furnace, such as steam pressure or water temperature, by a reversible electric motor 66 (see Group XXXV). In the event of the fuel feed being stopped completely the main driving motor may also be stopped by an auxiliary switch. The application of the gearing to a furnace stoker of the sprinkler type is also referred to in which an intermittent rotation of the fuel measuring shaft is effected and made variable by a clutch operated by the follower from the adjustable cam groove.
