Abstract: A rectangular boxlike member containing a light to be applied to the exterior of a building between studs e.g. at the sides of a door or window; a cover for the box, said cover being connected thereto and having a translucent panel of plastic or glass to emit light, said cover extending for roughly twice the length of the box so that the illumination is aligned with the upper part of the door or window, conforming thereto. The rest of the cover is opaque and extends to the ground level or to the bottom of the door or window.

Abstract: A filter construction having a hose attachment therefor comprising a pair of discs one of which is indented at the periphery thereof forming a holder for a snap ring for the mouth of a filter bag, and a screw-on hose attachment extending through one disc and screwed into the other disc, holding the assembly in fixed condition, together with a quick-disconnect attachment for a hose.

Abstract: A cycle rack for a trailer hitch the construction being such as to easily mount and dismount the cycle rack at the same time allowing for the normal function of the trailer hitch.

Abstract: A blister strip package comprising two coextensive sheets of heat sealable material provided with a first row of individual cavities for containing a product to be dispensed in one of said sheets, said first row of cavities being laterally aligned with a corresponding, opposing row of an equal number of second cavities in the same sheet, the cavity bearing sheet being heat sealed to the other sheet except in the areas defined by the cavities and, in one embodiment of the invention, being also heat sealed in areas spaced from the second cavities and adjacent to weakened lines for disruption of the covering sheet, whereby the second cavities can be pushed inwards and thus inverted to bear upon the covering sheet in order to thereby disrupt it at score lines or slits and to form a pull tab which can be grasped and pulled towards the aligned, respective pair of second and first cavities thereby peeling the covering sheet from the cavity bearing sheet and forming a direct access along predetermined lines to a sele

Abstract: An impervious cushion particularly adapted for scrap foam stuffing having vents comprising substantially imperceivable small slits in mutually spaced relation in the box edge between the upper and lower panels.

Abstract: The invention relates to method and apparatus for the treatment of wastewaters using a rotating biological contactor in combination with an adsorbent.

Abstract: An assembly including a series of tubes attached to a base tube sheet wherein the tube sheet is provided with relatively light corrosion resistant material at both sides, the sheet then being drilled through, corrosion resistant sleeves placed in the holes drilled, and corrosion resistant tubes located and fixed in the sleeves by rolling and welding.

Abstract: A circuit which allows for the simultaneous control of the bias voltages applied to the screen grids and control grids of output tubes while maintaining the ratio of said voltages, thereby providing a method for selectively varying a single plate characteristic (Power Output) of a tetrode/pentode vacuum tube.In the case of musical instrument amplifiers, it is a desirable effect to drive the power amplifier (output stage) beyond the point that said power amplifier is able to reproduce its input signal accurately, hence causing output distortion. Said point is known as the "Clipping Point".A clipping point is most usually achieved at high sound pressure levels which are uncomfortable and difficult to work under. By varying said voltages in the previously stated manner, one varies the clipping point accordingly, and therefore is able to obtain output distortion at variable sound pressure levels.

Abstract: An elongated metal bolt embedded in a brick and means at the ends of the bolt for holding the same tightly to the ends of the bricks, and collars inserted between the ends of the bricks and the nuts to balance the difference in expansion of the bolt and the brick under conditions of heat.

Abstract: A flytyer's scissors having a loop to place it on the operator's midfinger to dangle, and including a bowed-out arc to be pressed by the thumb against the forefinger to actuate the blades.

Abstract: An all-inclusive package comprising a book having an easily removable binding and cover, and removable leaves; in combination with a plurality of transparent plastic frames into which individual leaves from the book may be placed temporarily or permanently, means for hanging the frames for display, and means for holding the book, the frames and the hanging means together as a unit.

Abstract: A removable ball guiding attachment to the tongue of a trailer hitch having two diverging members guiding the ball of the trailer hitch in correct position with respect to the clamp on the tongue of the hitch.

Abstract: An effective and inexpensive hackle clamp comprising a loop of flat spring wire having free ends extending from the loop, the free ends being flatly fastened together inwardly from the terminal ends thereof forming a clamp which is easily opened by squeezing the sides of the flat wire in the loop area.

Abstract: A machine for removing stuck eggs from egg trays made of semi-flexible material with a series of depressions holding the eggs therein including plungers located beneath the trays and including means for raising the plungers, pressing them against the egg supporting portions of the depressions to partially invert the depressions, raising the eggs, and thereby releasing the eggs from the material of the egg trays, whereupon the eggs are lifted out and disposed of.

Abstract: A package comprising two sheets of heat sealable material, one of the sheets being relatively stiff and being provided with cavities for dispensing a product, the other sheet covering the cavities and the stiffer sheet. The covering sheet is longitudinally perforated along at least one edge of the package a short distance inward from the edge thereof; and from the area of the perforations inwardly, terminating short of the cavities, there are unsealed areas facilitating pealing the covering sheet in the direction of the cavities giving access thereto, after releasing a portion of said covering sheet from the cavity bearing sheet by bending along the line of the perforations and peeling.

Abstract: Safety device in the general form of an apertured disc which aids in keeping sparks and flames from paper, kindling, wood etc., from shooting up the chimney and possibly causing fire; the device also helps to stop soot build up and it controls the rate at which the wood burns, saving fuel.

Abstract: A wet air combustion system including a reactor, a steam boiler, a pressure control valve (PCV) to regulate the heat exchange of the boiler steam with the reactor effluent, and a sensor/responder coupled to the PCV monitoring the reactor influent temperature after preheat exchange with the partially cooled reactor effluent.

Abstract: A wood carrier in two separable parts, the parts being shaped in complementary angular form to carry wood, store it, and having means to selectively separate the parts to dump the wood.

Abstract: A supplemental clock dial for a clock comprising an annular transparent disc mounted centrally on a bushing driven to turn the hour hand, an hour hand on the annular disc, said disc rotating once in twelve hours and including the names of countries or cities around the world and showing the time in those places, the names of said countries and cities being mounted on balanced swinging members so that they are always upright; and including separate members showing the AM and PM indications for each of said countries or cities these members being swingingly mounted on the first named members and including means to turn them 180.degree. each twelve hours, and having weights for keeping the same in upright position for a period of twelve hours, whether AM or PM.
