Title: Improvements in or relating to a device for cooking eggs and for like purposes
IPC: A47J29/02
Filed: 1957-08-09
Abstract: 813,029. Boiling eggs. STEPHENS, R. R., and LEVITT, H. N. Aug. 9, 1957, No. 25198/57. Class 28 (1). [Also in Group XXXVII] Eggs are boiled in an upper chamber 2 filled with boiling water from a closed lower chamber 1 when boiled by a heater 4. Transfer of the water from 1 to 2 actuates a pre-set timer 16, electrical or clockwork, which at the end of the set time allows the water to be sucked back by the cooling vacuum into the lower chamber through aperture 17 in the water tube 6. The timer 16 after setting is held against actuation of the switch by a brake 15 which is released to allow the timer to start when the liquid is boiled over into the cooking chamber 2. A float 12 holds the brake 15 on until the level falls. The float 12 actuates through linkage 14 on the brake 15. Each time the clockwork timer 15 is set, it winds up a spring. If the timer 15 is electrical a bi-metal operates an electric switch to the heater 4. The water tube 6 is provided with a deflecting hood 8. The eggs are located in holes in a rack 11 which may be lifted out and used as a table stand. A two-heat element may switch on to low by the float 12 when the water has been transferred to the upper chamber. An indicator light 22, Fig. 1 (not shown) shows on, and a second light may be switched on when the time-switch brake 15 is released. With a hand-wound time clock wound up, the cessation of ticking indicates when the eggs are cooked.

Filed: 1922-09-19
Abstract: 187,585. Akt.-Ges. Brown, Boveri, et Cie. Oct. 19, 1921, [Convention date]. Addition to 14498/15. Automatic circuit-breakers with time limit actuation for ordinary overloads and instantaneous actuation for short-circuits wherein the armature acts upon the time-limit mechanism through a spring which is overcome on heavy overload as in the parent Specification, have the armature 3 mounted so as to have movement independent of the tripping lever 5 and the spring 6 connected between an extension 26 of the armature and the pawl 7. This arrangement ensures that the timemechanism pawl can never be acted on by a force greater than the force of the spring 6. In order to cut out the instantaneous action when desired a set screw 27 which normally passes through the eye 28 in the tripping lever and holds the armature and lever together is removed and inserted in the eye 29 where it locks the tripping lever and the pawl 7 together. Specification 103,113. is referred to also.

Title: Improvements in xerographic development
IPC: G03G9/12
Filed: 1963-06-26
Abstract: 1,035,236. Electro photographic processes. RANK XEROX Ltd. June 26, 1963 [July 2,1962], No.25392/63. Heading G2H. A method of forming, on a web 14, a visual record of a latent electrostatic image 11 on a support 12, comprises placing a quantity 15 of particulate toner which may be liquid or solid suspended in a non-conductive liquid carrier and establishing a line of contact between successive portions of the web and support member, whereby toner particles 17 are deposited on the web in the configuration of the image. The support 12 may be a xerographic plate. The web may be brought into contact with the support 12 by a roller 13, such that the quantity 15 of toner advances across the surface of the support 12 in front of the line of contact between the roller and support. The toner is charged with the same polarity as the image 11 for positive to positive reproduction and is stated to be repelled by electrostatic force towards the web 14. The toner is oppositely charged for reversal development and the roller may be electrically conductive in which case an electric potential may be applied to the roller to improve print quality. The image formed by toner particles 17 may be fixed by heat fusing or the toner may be self-fixing e.g. by solidification of wax on cooling. Examples of carrier liquids are hydrocarbons such as benzene, xylene, hexane, naptha, cyclohexane, trichlorethylene, chloroform, Frean (Registered Trade Mark), Genetrons and other liquids such as silicone, liquid and turpentine. The viscosity of the carrier liquids may be increased with the addition of paraffin wax and petrolatum. Toners include pigments, dyes, resins, metals, charcoal and graphite.

Abstract: 818,531. Valve gear. WINSLETT, B. H. M., and COXON, J. R. Feb. 21, 1958 [Nov. 22, 1956], No. 25667/56. Class 7(6) A poppet valve 3 is actuated positively in both directions by a pair of cams 13, 14, acting on a rocker lever 4 the pivot 9 of which is connected to a floating member 21 held in position by a piston 23 loaded by fluid pressure and yieldable against said pressure when the force between the valve and its seat exceeds a predetermined value. The inlet and exhaust valve 3, 3<SP>1</SP> are operated by identical mechanisms, the rocker pivot 4, 4<SP>1</SP>, being connected by links 20, 20<SP>1</SP>, to a common member 21. Each rocker is built up of plates 10, 11, and has.an opening through which passes the camshaft 15, Fig. 2, on which a pair of cams 13, 14, cooperates with cam followers 16, 17, carried by the rocker. If the valve 3 or 3<SP>1</SP> is prevented from closing fully on its seat, strain in the rocker mechanism is avoided by lifting of the pivot 9 or 9<SP>1</SP> against the force exerted on member 21 by the piston 23 which is loaded e.g. by the lubricating oil pressure. An initial clearance which exists between the block 21 and rocker box 1. when both valves are closed permits piston 23 to take up clearance between the valve and its seat, which arises through thermal expansion. Each rocker actuates its valve through a pair of pins 6 engaging between collars 7 on the valve stem, the valves being free to rotate when open; this rotation is assisted by having the pins 6 staggered relatively to one another and by having serrations on the pins and collars.
