Title: A high voltage isolating switch
IPC: H01H31/28
Filed: 1949-05-24
Abstract: 659,360. Air break switches. AKTIESELS KAPET PROTON, and MORCH, J. May 24 1949, No. 13872. [Class 38(v)] A high voltage isolator switch especially suitable for outdoor use has contacts. which cannot be easily iced-up and comprises a resilient contact blade 1 mounted with its greater width transverse to the swing- ing plane by means of a plate-spring hinge 5. The blade may be made of hard rolled copper or bronze and carry the current, but preferably the current is carried by a cable on the underside of the blade Fig. 2 (not shown) and the blade is of spring steel. The fixed contact 6 is of round-section copper bent into an open frame to provide a main contact 11 and spark contact 12, the contact 12 being higher than contact 11. The coacting surfaces of the contacts 1, 11, 12 may be coated with silver. The blade 1 is operated by an insulator 19 connected by an arm 20 to a crank 16 on a shaft 15 whereby when the latter is rotated clockwise by a chain 14 to close the switch, the blade 1 first engages the spark contact 12, and then on continued movement of the insulator 19 the blade is flexed, engaging the main contact 11 and leaving the spark contact 12. On opening the switch the blade again flexes and finally breaks circuit at the spark contact. This flexing also causes longitudinal movement of the blade contact-end whereby the coacting contact surfaces are kept clean, and the effect may be improved by making the blade concave on its contact-making side. The crank 16 rotates through slightly over 180 degrees between the open and closed positions and thus holds the switch locked. The blade 1 may carry a weight at its free end to act as a hammer in breaking the ice, and several switches may be mounted together and operated conjointly, in which case the shaft 15 may have a counterweight to balance the insulators 19. The fixed contact 6 may be mounted higher than the hinge 5 to hinder an arc being forced along the blade by a strong wind. In a modification, the blade is moved rectilinearly by compressed air to make a double-break.

Title: Manufacture of fertilisers containing trace elements
Inventor: MALEWSKI ANDRZEJ MARIAN
IPC: C05D9/02
Filed: 1956-05-07
Abstract: A fertilizer or fertilizer supplement is prepared from waste dry cells or batteries of the Leclanch<\>ae type, or from mercuric oxide-zinc cells after evaporation of the mercury, by comminuting the cells and thereafter heating with sulphuric acid to obtain a sulphate solution containing manganese, zinc, and, from Leclanch<\>ae cell terminals, copper.  In the case of mercuric oxide-zinc cells, a manganese dioxide material is added prior to the acid treatment. Excess acid is preferably employed and neutralising is then effected as a final stage with quicklime or ammonia.  The sulphate solution produced may be evaporated to crystallize the sulphates and the mother liquor recycled, or the solution may be evaporated to dryness and the sulphates decomposed by heat.  The sulphur trioxide is adsorbed.  Further elements such as copper or boron may be added before the acid attack and the sulphate solution produced may be employed as a fertilizer spray. Alternatively the solid products may be added to superphosphates.

Title: Improvements in or relating to absorption refrigerating machines
IPC: F25B17/00
Filed: 1928-05-14
Abstract: 295,371. Sulzer FrÞres Soc. Anon. Aug. 11, 1927, [Convention date]. Thermally-actuated valves. - The supply of heat to the generator-absorber A of a refrigerating system is cut off automatically by means operated by a thermostat influenced by cool refrigerant overflowing from the evaporator. As shown, heating current is supplied to the vessel A through a tilting switch 48 so long as cooling. water flows to a waste pipe 20 through a counterbalanced tank 45, but is cut off when the water is diverted by a valve 18 through the cooling- coil 13 of the generator-absorber by the control means. A thermostatic element 27 arranged in the part of the generator-absorber communicates with a bellows member 25 connected to a spring arm 30 pivoted at one end at 29, and another thermostat 28 is arranged in a passage 9 and communicates with a bellows member 26 connected to another arm 38 pivoted at the point 29 but intermediate its ends. These arms are provided with pawls 31, 39 adapted to engage a notch 32 in a disc 34 on the spindle of the valve 18 which directs the water flowing through pipe. 17 from the condenser either through pipe 21 to waste or through pipe 19 to the generatorabsorber cooling coil 13. At the beginning the valve is set by hand or otherwise against the action of a spring so as to cause the water to flow through pipe 21 and thus initiate the heating period, and the pawl 31 of the thermostat 27, which is cold, locks it in this position. When the hot gas begins to flow around the thermostat element 28 it causes the bellows 26 to expand and push the other pawl 39 into the same locking position, while after a time the first thermostat becomes heated and releases its pawl 31. When generation is complete the cool excess refrigerant returning to the tube 9 causes the bellows 26 to contract and release the pawl 39 and so unlock the water valve to establish the absorption period. The movement of the bellows 26 may be adjusted by a nut 50 so as to ensure overflow of more or less cool refrigerant before the reversal.
