Abstract: 984,266. Windscreen wipers. J. E. LINDBERG. May 9, 1961 [July 20, 1960], No. 25360/60. Heading A4F. [Also in Divisions F1, G1 and H2] Windscreen wipers are operated by double-ended piston 51 which is contained in cylinders 60, 61 and sealed thereto by flexible, impervious diaphragms 55, 56. The cylinders contain metal hydrides 62, 63 of the type that outgas upon heating and ingas upon cooling which hydrides have embedded therein electric heating filaments 64, 65. The wiping motion is initiated by depressing switch 90 which causes current to flow through filament 64 which heats hydride 62 causing it to outgas and move piston 51 to the right thus compressing the gas in cylinder 61. When the pressure is sufficiently high in cylinder 61, pressure switch 86 is activated by member 87 which causes switch arm 98 to close and switch arm 92 to open, thus filament 64 begins to cools and filament 65 heats up causing hydride 63 to outgas and move piston 51 to the left when the cycle is repeated upon the activation of pressure member 85 similar to above. The cycle continues after switch 90 is released. Specification 961,146 is referred to.

Title: A method and apparatus for operating charging installations for one or more cupola furnaces
Inventor: FAHLAND JURGEN VON
IPC: F27B1/20
Filed: 1959-07-23
Abstract: 925,705. Charging cupola furnaces. BADISCHE MASCHINENFABRIK A.G. July 23, 1959, No. 25384/59. Class 51 (2). [Also in Group XXX] Apparatus for automatically charging a cupola furnace comprises a truck 1 with two skip-receiving areas I and II moving between charging hoppers B and C and an elevator shaft A, skips 2, 2<SP>1</SP> traversing the shaft A carried by the cross-yoke 30 and winch rope 28 of a travelling web, and a spring-pressed feeler member 3 at each receiving area associated through linkage 5-11 with a lever 16 carrying a roller 17 engaging a limit switch E1 or E2 according as there is or is not a skip on the said receiving area. The yoke has rollers 32, 33 engaging guide rails 31 which are helically arranged to turn it through 90 degrees. The hopper B supplies a given weight of lime and coke and hopper C a given weight of scrap metal, Limit switches E1-E9 are so disposed and inter-related that whether a skip is placed on area I or II the truck automatically moves below the charging hoppers in turn, returns to the shaft where the full skip is replaced by the empty one, and then returns to the charging hoppers while the empty skip is being taken to the hoppers for loading, the full skip is raised up the shaft and returned empty. Operation.-The inter-relation and function of the limit switches is as follows: E1 is operated by the lever 16 when a skip is disposed on the appropriate skip-receiving area I or II to stop the truck-driving motor if switches E4 and E5 are depressed. If E4 and E5 are not depressed, switch E1 is shortcircuited, leaving the truck motor to be stopped by the following switch E2. Switch E1 also starts the hoist motor in the " up " direction. E2 is operated by the lever 16 to stop the truck-driving motor when there is no skip on the appropriate area I or II. It also starts the hoist motor in the " down " direction. E3 and E9 are reversing switches for the truck-driving motor. E4 and E5 are depressed by the yoke 30 in its lowermost position. As indicated above and shown in Fig. 1, if the truck approaches the shaft with a loaded skip in area II and an empty skip is at the top of the shaft, switch E1 is operated, but is short-circuited, allowing the truck to stop under control of E2 with area I below the shaft and receive the empty skip. On reverse movement of the truck however, with switches E4 and E5 depressed by the yoke 30, switch E1 will stop the truck with area II below the shaft for removal of the full skip. E6 is operated in one direction by the rising yoke to start the truck-driving motor, moving the truck towards the charging hoppers. In the reverse direction, it is operated by the falling yoke to cut-out the hoist-driving motor. E7 and E8 disposed below the charging hoppers operate so that an empty skip stops below them in turn, E7 operating like switch E1. They also operate hinged doors for the hoppers, closing of which doors starts the truckdriving motor moving the truck towards the elevator shaft.
