Abstract: A glassware-making apparatus has a premold adapted to make a parison and a final mold spaced from the premold and adapted to receive and blow-mold the parison. An arm removes the parison from the premold and displaces it along a path to the final mold. A scrap chute can be displaced by a controller into a position intercepting this path to catch the parison and divert it to a recycle/scrap bin when the controller detects a malfunction at the final mold or downstream therefrom.

Title: Current transformer with annular case to be built in a metal cast high-tension switchgear installation
IPC: G01R15/18
Filed: 1981-07-11
Granted: 1984-09-26
Abstract: A current transformer having at least one ring-shaped core with a secondary winding mounted thereon, and a primary conductor, located within its casing. An inner tube is provided between the ring-shaped core and the primary conductor, one end of the tube being electrically connected to the casing and its other parts electrically insulated therefrom. A cylindrical, electrically conductive screening shield at least partially overlaps the inner tube and is electrically connected to the casing on the side of the ring-shaped core which is distal from the electrical connection between the casing and the inner tube, while the other parts of the shield are electrically insulated from the casing. This overlap forms a short-circuit loop for any steep progressing wave which is generated when switching on a potential-free part of the circuitry, or when due to an interruption, a small capacitive current breaks off. The short-circuit loop thus prevents the generation of high inductive voltages at the secondary leads of the current transformer. The overlap also enables a steep progressing wave to progress without reflection and without capacitively influencing the potential of the secondary winding.

Abstract: A subscriber line interface circuit is described wherein current supplied to a telephone subscriber line from a shared voltage source such as a DC/DC converter is regulated thereby permitting a regulated line current to be supplied to a plurality of line circuits from a single shared voltage source. In accordance with the present invention, both the dc line feed and the ac transmission requirements of a subscriber line interface circuit for a telephone exchange are implemented in a single circuit incorporating ac and dc impedance synthesis techniques. A significant reduction in the heretofore required expensive and bulky discrete components of the subscriber line interface circuit is achieved.

Abstract: PCT No. PCT/US81/00881 Sec. 371 Date Aug. 27, 1982 Sec. 102(e) Date Aug. 27, 1982 PCT Filed Jun. 26, 1981 PCT Pub. No. WO83/00211 PCT Pub. Date Jan. 20, 1983.In one exemplar embodiment, an improved evaporating coil defrost control (28) for use in a refrigeration system is disclosed, and which includes a pair of thermostatically controlled switch contacts (42, 44) positioned adjacent the evaporator coil (14) and responsive to the temperature of the coil, the contacts being heated by a resistor or thermister heater (46) to maintain the temperature of the contacts above a predetermined "low" temperature level. The refrigerator compressor (18) is operated through one of the normally closed switch contacts (42) when the switch (40) is maintained above the "low" temperature level. A defrost initiation means (48) de-energizes the heater (46) when defrost is necessary, permitting the thermostatically controlled switch contacts (42, 44) to cool below the "low" temperature level and closing the normally open switch contact (44) to actuate a defrost means (26) to defrost the evaporator coil (14). The defrost means (26) heats the evaporator coil (14) until the melting point of the frost or ice is reached to remove frost and ice, and in turn heats the switch contacts (42, 44) until a predetermined "high" temperature level is reached for changing the state of the switch (40) and re-energizing the compressor (18), cooling the evaporator coil (14), and de-energizing the defrost means (26). The resistor or thermistor heat (46) is re-energized to maintain the temperature of the thermostatically controlled switch contacts (42, 44) above the "low" temperature.

Abstract: The disclosure relates the strength of ends (10) used on metal beverage containers. 
<??>Such ends generally comprise a central panel portion of a substantially planar character, a surrounding U-shaped sidewall having inner and outer legs, a curved intermediate portion integrally joining the inner leg to the U-shaped sidewall, and the peripheral curl extending from the outer leg for double seaming the end onto a can body. 
<??>The intermediate portion and adjacent central panel portion are firmly supported by a die (27) while a clamping force is placed on an annular band of the upper surface (45) of the end at the intermediate portion. The clamping force is increased until metal flows inwardly and outwardly from the contact point (34) resulting in a free compression doming of the center panel and an outward deflection of the inner leg. An end of increased buckle resistance is thereby produced which end is approximately within standard dimensions such that customers can use the end of the existing seaming equipment without alteration. An optional feature is provided to minimize the compression doming by clamping a peripheral band of the end with a hold-down pad (44) while the metal flowing is accomplished. This reduces the dome depth and results in a strengthened end having a dome depth very close to standard specifications.

Abstract: Ultraviolet radiation is the wavelength range between 150 and 300 nanometers, which both generates ozone (O3) and has a germicidal effect both in ambient air and in a pure oxygen atmosphere, is performed in a highly energy-efficient manner, by utilizing a low-voltage, low-pressure gas discharge lamp, by using a radiation-transparent quartz tube, by equipping it with a long-lasting sintered electrode pair and filling it with a mixture of gas vapor and mercury vapor, by disposing a circuit device between the mains and the gas discharge tube which rectifies the mains alternating current and effects smoothing voltage multiplication, and by coupling this circuit device with an automatic, dry-switching commutator device for the direct current of the gas discharge lamp, in order in principle to avoid a mercury-vapor dissociation (cataphoresis) which would reduce the effectiveness of the radiation. As a result of the direct current operation, the energy efficiency of the UV radiation generator is improved by up to 30%, as compared with direct operation of the gas discharge lamp with alternating current and a standard alternating current choke, because of the reduction in heat losses both in the gas discharge process and in the voltage multiplier choke.
