Title: Improvements in electric switches
Inventor: PEREI LASZLO EDWARD
IPC: H01H21/02
Filed: 1963-07-02
Abstract: 1,026,530. Snap-action switches. L. E. PEREI AUTO DEVICES Ltd. July 1, 1964 [July 2, 1963], No. 26190/63. Heading H2B. An electric switch is actuated by a hollow lever, enclosing an indicator lamp in a translucent head and connected to a resiliently mounted movable contact member which is movable from an " off " position in which it engages a first contact only to an " on " position in which it bridges a gap between the first contact and a second contact. In the latter position also a further connection is made from the second contact, through the movable contact member to the indicator lamp. The hollow handle 29, Fig. 1 (not shown), is pivoted in a boss 23 by grub screws 32, the boss being carried on a plate 24 which is attached to a body 10 by bent-over lugs 25. A lamp bulb 36 is retained within the handle by a translucent cover 37 and its centre contact 35 engages an insulated metal strip or rod 31, the inner end of which carries a compression spring 19 which bears on a metal ball 18, to which it imparts a snap-over action. The body carries two contacts 12, 13, Fig. 2 (not shown), the latter of which is shaped as a channel 17 along its lower link, in which the ball 18 runs. In the " off " position of the switch the ball is held at the right-hand end of the limb 17, in this Figure, but when the switch handle is moved to the " on " position the ball is snapped across towards the left where it also makes contact with the live contact member 12, to complete the external circuit. At the same time connection is made from the contact 12 through the ball 18, spring 19 and rod 33 to the indicator lamp, which has an earth return.

Title: Improvements in bleaching agents, and method of forming the same
IPC: C07C409/34
Filed: 1929-08-29
Abstract: 339,336. Ellis, R. E., (Pilot Laboratories, Inc.). Aug. 29, 1929. Bleaching oils, fats, waxes, and soaps.-Complex organic peroxides formed by treating mixtures of the acid chlorides of higher fatty acids and benzoyl chloride, chlorbenzoyl chloride, or bromobenzoyl chloride with peroxidizing agents are used as bleaching agents for soaps, oils. fats, and waxes. The fatty acid chlorides may be those .derived from caproic, lauric, or oleic acid, or any natural or artificial mixture of such acids, for example, the mixed fatty acids of cocoanut oil. Excess of the fatty acid chlorides is preferably employed in the reaction, so that the products contain simple fatty acid peroxides in addition to the complex peroxides. Solutions of these complex peroxides in animal, mineral, or vegetable, oils may be sprayed or otherwise disseminated throughout the material to be bleached. These complex peroxides are also stated to increase the bleaching power of other peroxides in admixture therewith.

Abstract: 385,037. Feeding webs. GOSS PRINTING PRESS CO. OF ENGLAND, Ltd. and SMITH, E. J., 18, Whitefriars Street, London. Sept. 21, 1931, No. 26385. [Class 100 (i).] Web controlling or braking mechanism for multiple roll carriers is provided with a brake common to the several rolls adapted to be coupled to each roll so that the braking action can be transmitted to the centres of the rolls. The wet roll carrier, for supporting an active roll A and reserve rolls B, C, comprises a spider 3 having three radial arms, and mounted on a shaft 4. The active roll is subjected to the action of braking straps 6, weighted at 9 and fastened at the lower end to a fixed point. In order to prevent the roll from rotating after the outer layers have been stopped, the spindle of the active roll is controlled independently of the action of the straps 6. The web passes round a roller 26 on a spring-controlled arm 27, when the tension of the web decreases, the arm moves into the position shown in broken lines on the left and causes, through links 18 .. 21, a brake band 16 to be applied to a drum 15. The drum is geared with an idler wheel 11 and wheel 10 on the shaft of the active roll so that the braking.action is transmitted to the centre of the roll. Each wheel 11 is adapted to be moved in and out of gear by nuts 14 and bolts 13.

Class 126 [Also in Group XIII] In a combined air and water heating stove (see Group XIII) some of the heated air flowing upwardly through a duct 38 at the front of the stove, passes through a port 38a in the stove casing to support combustion, the quantity of combustion air being regulated by a damper 42 actuated through a manually - adjustable thermally - sensitive element 39 in the water-heating space 4. Combustion may also be regulated by means of a manually-operable damper 28b in the combustion gas outlet from the fire chamber, the damper having an arm 28c pivoted to an arm 28c extending from a control knob 28f as shown in Fig. 5. The grate comprises two sections 6, 7 individually rockable by means of knobs 14. To remove ash a knob 14 is rotated to the extent permitted by a gap 18 in the flange 16 of the knob, the ends of the gap being engaged by a stop 19 to limit the rotational movement. To enable the grate sections 6, 7 to be turned fully to deposit clinker &c. in the ash pan 2e, the stop 19 may be withdrawn against the action of a spring sufficiently to permit the necessary rotational movement of the knobs 14, this movement being limited by the extent of a recess 17 provided in the flange 16 of the knob.

The cut length 12 is fed between a block 15 and leaf spring means 14 by the cutter 10, and engagement by the arm 13 draws it between projecting flanges of a forming roll 16, forming a staple 12a held in longitudinal grooves 17 of the arm by a resilient finger 18. At the stapling position a lever 22 carried on a pivot pin 21 of the cylinder 20 is actuated by the cam means 25, 33 to cause a stapling stroke of the arm 13, pivoting of the member 24 compensating for a greater linear speed of an anvil 27 that that of the cylinder periphery. Feeding of the wire 12 is effected by cooperating rollers (28), (28a), Fig. 3 (not shown), breaks (29) in the periphery of one roller (28) causing feeding to be cyclically interrupted for operation of the cutting means 10. To stop the feed, the rollers (28), (28a) may be disengaged by electromagnetic means (31), a control (39) being provided to interrupt feed when the wire supply is exhausted.

Abstract: 535,189. Marking indications on roads &c. STRUTT, C. B. P. Sept. 29, 1939. No. 26906. [Class 132 (ii)] A marking machine for road surfaces comprises in combination a vehicle, one or more stencil members formed in a surface adapted to roll over the ground and mounted on the vehicle in such manner that they can be brought in contact with the ground during progress of the vehicle and means to apply a marking material such as paint, to the ground surface with the interposition of the stencil member or members. An arm 22 pivoted on a bracket 21 projecting from the side of the vehicle carries a hollow axle 23 passing through the centre of a cylindrical rolling stencil wheel 24. The stencil wheel comprises two end portions 25, 26 adjustably spaced apart to determine the width of the line and bridged by one or more plates 31, Fig. 3. The edges of the plates 31 and of the inturned edges of the end portions 25, 26 define the shape of the mark made on the road. The paint, is sprayed from a gun 33 supplied with paint and air under pressure by pipes passing through the hollow axle 23. Spring-pressed scrapers 41, 43 remove excess paint from the interior of the stencil wheel and direct it into a paint receptacle 39. Further scrapers 54, 57 carried by a framework surrounding the stencil wheel, remove excess paint from the exterior of the wheel. The framework also carries a sprocket wheel 60 and cam 63 diven from the hub of the stencil wheel. At every alternate revolution of the stencil wheel the cam opens the valve to spray the road during the time the stencil wheel takes to roll from one plate 31 to the other thus producing a broken line. By removing the plates 31 and holding the valve 68 permanently in the open position by means of a catch 70 a continuous line may be painted. A handle 65 is provided on the framework to permit manoeuvring of the stencil if it is detached from the vehicle. Two sets of guide rollers 86, 88 are provided to guide the driver of the vehicle along the line to be marked. The road surface is dried by a nozzle 78 supplied with hot gases from the engine exhaust and grit is removed by an air spray 76 and brush 79.
