Abstract: Abstract of the Disclosure The invention relates to a method for die casting lead-alloy battery terminal connectors through an aper-ture in a plastic battery case.  This involves providing a battery case containing a cellular partition and having an aperture in its wall.  Molds are positioned on opposite sides of the wall to form a die mold about the aperture. One of the molds has an opening for introduction of molten lead and a heater in the opening to prevent solidification of the lead.  Molten lead is then injected at a preselected pressure around the heater through the opening to form the terminal connector.  This produces a connector having a significantly reduced tendency to allow leakage of battery electrolyte.

Abstract: ABSTRACT            A method of forming a simulated lead light involves the application of opaque canes to the surface of a transparent or translucent sheet of material, in which the opaque canes are built up successive applications of adhesive and opaque particulate material, such as silicon carbide.    The adhesive can be screen printed onto the carrier surface and the particulate material can be dusted onto the printed adhesive.  The application of adhesive and particulate material can be repeated until a raised cane of desired thickness is built up on the carrier surface to simulate a lead cane.  The method can also be used in conjunction with the screen printing of colours onto the carrier surface to simulate stained glass separated by simulated lead canes.

Abstract: ABSTRACT OF THE DISCLOSURE     A wick assembly for a liquid fuel combustion apparatus is structured by laminating a main wick and an auxiliary wick, and sandwiching a separator of an oil-impermeable material therebetween.  By being so structured, deterioration of the main wick can be avoided which otherwise would result in a loss of heat production.  A material having a large oil containing ability can be selected for the main wick, and the distance between the oil level and top of the wick can be made shorter.  Fire-spreading time of the wick assembly after a lapse of long service period is still as short as that at the beginning of the service, and generation of an objectional odor and carbon monoxide at the time of ignition can be suppressed.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to a new, generally applicable method for opening mineral deposits for prospection purposes and for subsequent mining, where necessary ramp systems, drifts or tunnels (developments), which previously were laid in dead rock, now entirely or substantially entirely are laid in the ore.  The method further renders it possible, that the deposit can be pre-developed, i.e. that within the deposit different ore grades such as ore types and/or contents are exposed and made immediately and continuously accessible in such a manner, that the subsequent mining at every given occasion can be adjusted and controlled in the desired direct-ion, whereby an adjustment to the market outlook can be made The method, therefore, must not only be regarded as a new method, which during the prospection phase of a deposit reduces the venture risk and during the subsequent mining maximizes the income, but also as an entirely new mining strategy, because the method produces ore, i.e. economically mined deposits of mineralizations which previously did not enconomic-ally justify mining.

Abstract: ELECTRONIC SENSING AND DISPLAY   SYSTEM FOR A REFRIGERATOR     ABSTRACT OF THE DISCLOSURE         A sensing and display system for a refrigerator includes a plurality of sensors which are sequentially monitored at a first rate in order to determine whether certain conditions in the refrigerator are within predetermined ranges.  If the sensed conditions are within their ranges, a first plurality of visual indicators are sequentially energized at a second rate and a separate indicator is continuously energized to indicate normal operating conditions.  If the system detects that one or more of the sensed conditions are not within their ranges, the first plurality of indicators and the separate indicator are de-energized, and one or more of a second plurality of indicators are energized to inform the user of the existence of one or more abnormal operating conditions.  The system delays an abnormal condition indication, such as an overtemperature condition, until the condition has existed for a predetermined period of time.  The system also provides separate and distinct indications for a presently existing overtemperature condition and a previous overtemperature condition which has since disappeared.

Abstract: INDUCTOR AND METHOD FOR ANNEALING WORK HARDENED PORTIONS OF STRUCTURAL BEAMS     Abstract of the Disclosure A method and inductor are provided for annealing the corners of an elongate hollow structural beam in which the corners become work hardened when the beam is produced by cold working initially flat metal plate to the hollow beam configuration. The corners of the beam are inductively heated progressively along the length of the beam in a manner which concentrates heat in the corners and controls the spreading of heat into the sides of the beam from the corners so that the work hardened areas are annealed to provide for the corners and walls to be more uniform in hardness and strength in connec-tion with use of the beam as a structural member.  The inductor for so controlling the heating encircles the beam and has arcuate portions each magnetically coupled with a corner of the beam and progressively diverging with respect to the walls of the beam adjacent thereto, and portions between the arcuate portions which overlie the side walls of the beam and are offset radially outwardly with respect to the arcuate portions.

Abstract: ABSTRACT OF THE DISCLOSURE, A method for making a direction sensitive contrast enhancement filter for a shadow mask color cathode ray tube is disclosed to minimize the amplitude of moire interference patterns to unnoticeable or unobjectionable levels.  For a particular color cathode ray tube phosphor dot size, the light transmission through a direction sensitive enhancement filter having a given hole size and spacing is determined mathematically. The filter is then moved a number of fixed increments with respect to the phosphor dot and the light transmission is determined for each incremented position. The variation in light transmission as the filter is moved incrementally  across the phosphor dot is the data recorded.  This procedure is repeated for different hole sizes and different hole spacings and the data graphed to find the minimum light transmission variation.  At this minimum light trans-mission variation moire patterns are reduced to unnoticeable or unobjectional levels.  A selected planar material then has holes or optically clear channels  of the selected radius and spacing placed therethrough to make the filter.
