Abstract: 282,646. Warner Electric Brake Corporation, (Assignees of Warner, A. P., and Cadman, A. B.). Dec. 22, 1926, [Convention date]. Actuated or applied by running axle or wheel; electric and magnetic; blocks and shoes acting on drums; cone and disc.-A brake for vehicle wheels in which brake shoes or the like are applied to a brake drum by the momentum of the vehicle comprises a pair of annular electromagneti cally attracted friction elements urged towards each other by a spring, one of which rotates with the wheel and the other of which is oonnected to the end of a crank arm on a rock shaft disposed paralles to the axis of the drum, the movement of the shaft effecting the application of the brake. The brake proper comprises a pair of shoes 23 adapted to be applied to a drum 16 secured to the spokes 10 of the wheel and provided with a lining 19. The shoes are adapted to be expanded by either of two cams 28, 28<1> disposed between their ends and carried by shafts 41, 43 mounted in a member 33 fixed to the axle 13. The shafts 41, 43 carry arms 42, 45 respectively, one of which is connected by a rod 46 for direct hand or foot operation and the other to the electromagnetic clutch device. The shoes are positioned laterally in the drum by a pair of adjustable bolts 37 passing through the fixed member 33 and provided with heads engaging slots 38 in the shoes. The electromagnetic clutch for applying the shoes comprises an annular member 47 slidably mounted upon the member 33 and provided with a winder 50 and adapted to engage a flange 21 on the brake drum 16. Bolts 55 hold the clutch member close to the flange 21. Current is supplied to the coil 50 by means of a pair of segmental blocks 72 secured to the member 47 and connected to the ends of the, coil, a pair of spring-urged plugs mounted on the casing 53 and connected with the leads 67 being in contact with the blocks 72. The springs of the contact plugs serve to keep the members 47, 21 in contact, thus maintaining the reluctance of the magnetic flux circuit through these members at a constant low value. The clutch member 47 is provided with a pin 57 working in a slot 58 in the casing 53 and connected by a link 59 to the arm 42 on the cam shaft 41. Thus when current is supplied to the coil 50 the member 47 becomes clutched to and partly rotated by the flange 21 of the brake drum 16 and the cam 28 is thereby turned to apply the shoes 23 to the drum. Covers and protectors for brakes.-The electromagnetic dutch member 47 is encased by an extension 53 of the fixed member 33 which carries the cam shafts 41, 43 of the shoe brakes. An inclined deflecting surface 54 is formed on the flange 21 of the brake drum 16 to assist in preventing water from entering the space between the flange and the casing 53. The slot 58 in the casing 53 through which the pin 57 on the clutch member 47 projects is closed by a plate 61 carried by the pin and guided by a pin 63 passing through a slot 64 in the plate, a spring on the pin 63 serving to hold the plate against the casing.

To ensure that the lower rail of a curved grille does not bend upwardly when the grille is extended a pair of vertical pivoted links are connected between the top and bottom rails.
Patent GB-749881-A (GB)
Title: Octane-1:8-diol
Inventor: ABBOTT LESLIE STEPHEN
IPC: C07C31/18
Filed: 1953-11-27
Abstract: Octane-1.8-diol is prepared by a process comprising reacting together butadiene and isopropylbenzene hydroperoxide in an aqueous liquid medium containing a ferrous salt, hydrogenating the resulting unsaturated compound at relatively low temperatures, the hydrogenation being terminated when substantially all of the ethylenic unsaturation has been removed, and subjecting the saturated compound thereby produced to acid-catalysed decomposition by pyrolysis in the liquid phase.  In the first stage butadiene, isopropyl benzene hydroperoxide and the ferrous salt react to give the bis-a .a -dimethylbenzyl diether of octa-2:6-diene-1.8-diol. This is subsequently hydrogenated to the corresponding saturated diether at a temperature up to about 150 DEG  C.  The saturated diether is then pyrolized using an acidic catalyst, e.g. an inorganic acid, fuller's earths in their acid-activated and heat-activated forms, organic sulphonic acids, sulphonated phenol-formaldehyde and sulphonated styrenedivinyl benzene polymers and substances such as vermiculite, silica gel, kaolinite, illite and attapulgite.  The isopropylbenzene hydroperoxide starting material may be present as the isolated compound or in the form of a crude reaction product obtained, for instance, from the oxidation of isopropylbenzene.  This reaction product may contain by-products such as acetophenone and phenyl dimethyl carbinol.  Ferrous sulphate is the preferred ferrous salt.  The temperature at which the first stage is carried out is preferably below 20 DEG  C. and for the pyrolysis is 150-250 DEG  C. The pyrolysis results in the formation of the diol and a -methyl styrene which may, if desired, be converted to the isopropylbenzene hydroperoxide starting material by hydrogenation and oxidation.

Filed: 1948-12-22
Abstract: 683,464. Tipping containers into vehicles; lever load-handling machines. SOC. SOVEL VEHICULES ELECTRIQUES INDUSTRIELS. Dec. 22, 1948. [Jan. 31, 1948] No. 33065/48. Classes 78 (iii) and 78 (iv). As shown in Fig. 2 a bin 9 to be tipped into a refuse vehicle is supported by hooks 8 from a carrier 6 which is mounted on the body of the refuse vehicle by means of a pair of spaced. quadrilateral linkages 1, 2, 5 pivoted at 3, 4 to the vehicle body and preferably of parallelogram form. The Linkages are operated by cables 16 19 passing round pulleys 14 free on the pivots 3 and round pulleys 13 free on pivots 7 but integralwith the carrier 6, the cables being secured at 15 to the pulley 13. The carrier 6 normally rests on abutments 11 on the links 5 and is held in this position by latches 12 so that when the ends 16 of the cables are pulled the bin 9, carrier and link 5 are raised bodily. This motion continues until a member 17 on the link I engages the latch 12 to release it and simultaneously the links 1 engage fixed stops 18 on the vehicle body. Continued operation of the ends 16 of the cables then cause the bin 9 and carrier 6 to turn about the pivot 7 to discharge the contents of the bin through a loading orifice in the vehicle body. During the latter motion the bin 9 engages a flap in the loading orifice pivoted about an axis 28, Fig. 9, coincident in this position with the axis of the pivots 7, and pushes the flap inwardly, an orifice being formed in the flap to permit passage of the refuse. A hinge is provided to withstand the reaction of the flap on the bin and carrier and comprises arcs 31, 32 carried by the carrier 6 which engage a roller 29 of resilient material and a fixed arc 30 mounted about the axis 28. The cables 16, 19 are operated by one or more hydraulic jacks and by tension springs secured to the ends 19 of the cables. The cables 16, 19 and pulleys 14, 13 may be' replaced by chains and sprockets, and in one construction, an endless chain passes round the sprockets, the sprockets replacing the pulleys 14 being driven by racks operated by hydraulic jacks. The device may also be employed for feeding coal and ore into furnaces or for feeding concrete mixers.

Abstract: Sintered bearing metal is made by a powder metallurgical process from a mixture comprising Al and 0.25 to 2.0 per cent of hard particles of aluminium oxide.  The Al may be pure or may contain one or more of the following by per cent: Si 0.2 to 11, Cd 0.05 to 5, Cr 0.1 to 2.25, Mg 0.05 to 3, Pb 0.1 to 3, Cu 0.1 to 5, Ni 0.1 to 4, Sn 0.01 to 0.3, Bi 0.1 to 5, Iu 0.03 to 0.5, and an impurity quantity of Fe. The aluminium oxide may be in the form of fused alumina "Turkish emery", corundum or tabular corundum, and may be in the form of 100 to 600 mesh power.  The metals may be of 60 to 325 mesh.  The mixture may be briquetted at a pressure of 30,000 to 120,000 pounds per square inch and then sintered in an inert atmosphere for 5 to 120 minutes at a temperature of 1000 to 12000 DEG F.  The inert atmosphere may comprise a mixture of 20 per cent CO, 3 per cent H, and 77 per cent N, or a mixture of 1.5 per cent CO, 1.5 per cent H, and 97 per cent N.  The bearing may be solution heated for 8 to 15 hours at 900 to 1050 DEG F. in an inert atmosphere, water quenched, precipitation heated for 5 to 10 hours at 300 to 400 DEG F., and then cooled in water.  Instead of briquetting under high pressure before sintering, the powder may be loosely filled into a mould and may contain a relatively small amount of an ingredient (e.g. Cd), having a lower melting point than the Al.  Alternatively, before sintering, the powder may be spread on a steel backing strip having a thin electro plated metal on its surface.  The sintered metal may be used for piston pin bushings, camshaft bushings, balancer shaft bushings, and thrust washers.
