Abstract: Abstract of the Disclosure A single lighting fixture for mounting in front of a large billboard having a horizontal length approximately two times as long as its vertical length is disclosed. The lighting fixture comprises lamp housing having a lamp positioned therein with the lamp being approximately horizontally positioned in the housing. A new and novel reflector is positioned on one side of the lamp and is designed to reflect the light radiating from the lamp in such a manner that the bottom surface of the reflector is utilized to light up the approximate central portion of the billboard while the sides of the reflector are used to light triangular shaped side corners of the billboard. A refractor is positioned on the lamp housing to totally enclose the lamp with the refractor comprising in part three phase light control prism elements for stray light control.  The combination of the reflector and refractor is designed so as to illuminate the opposite adjacent corners of the billboard with approximately 80% of the light quantity illuminating  approximately  30%  of  the  billboard  corners  and approximately 20% of the light quantity illuminating 70% of the edge of the billboard.

Abstract: Abstract A self-emulsifying anaerobically curable composition is disclosed.  The composition is rendered self-emulsifying upon mixing with water by incorporating certain polymerizable monomers with surfactant properties, referred to as surfactant monomers,in a concentration range of about 1% to about 80% by weight of the composition.  The preferred surfactant monomers are the reaction product of a surfactant, containing an active hydrogen atom, particularly from an hydroxyl or amino group, and an isocyanate acrylic monomer.  The surfactant monomers can be used in any anaerobically curing monomer or monomer mixture in which they are compatible.    These self-emulsifiable compositions have the advantages of being readily removable from surfaces by washing with water, without the disadvantages of loss of bond strength, solvent resistance or migration of the surfactant to the surface of the cured composition.  The surfactant monomers are co-polymerizable with the anaerobically curable monomers.          These self-emulsifiable compositions are especially useful in impregnation processes where uncured resin must be removed from areas which are difficult to wash, such as small, blind holes.

Abstract: ABSTRACT: "A push-pull amplifier".             For a satisfactory cross-over behaviour of the transistors T1 and T2 of a push-pull amplifier com-prising an input 2 and an output 3, it is necessary that the sum of the base-emitter voltages of the transistors T1 and T2 remains substantially constant. For this purpose a first voltage-current converter 5 is coupled between the base and the emitter of transistor T1, the inverting input of this converter being coupled to the base of transistor T1 via a first reference-voltage source 8 and the non-inverting input to the emitter of transistor T1. Similarly, a second voltage-current converter 9 and a second reference-voltage source 12 are arranged between the base and the emitter of transistor T2. The output currents of the first and the second voltage-current converters 5 and 9 are compared with each other in the combining circuit 14 which drives the control amplifier 15, which in its turn controls the base-emitter voltage of transistor T2 in such a way that the sum of the base-emitter voltages of transistor T1 and T2 remains constant. The push-pull amplifier exhibits a  mini-mal amount of second-harmonic distortion, because only the difference of the errors introduced by the first and the second voltage- current converters 5 and 9 is of importance in this respect and these errors are substantially equal to each other due to the method of fabrication of the voltage-current converters.

Abstract: ABSTRACT OF THE DISCLOSURE      A nucleic acid hybridization assay involving a labeled probe and formation of a hybrid having epitopes for an antibody reagent.  The label provides a detectable response which is measurably different when the labeled probe is comprised in a hybrid that is bound by the antibody reagent compared to when not comprised in such a hybrid.          Particularly useful antibody reagents are antibodies such as anti-DNA'RNA, anti-RNA'RNA and antibodies to intercalated duplexes which do not bind substantially to single stranded nucleic acids.  Modulation of the label response can be accomplished in a variety of ways such as by steric inactivation or hindrance or by labeling the antibody reagent with a second label which interacts with the first label. The assay is particularly advantageous because no separation of hybridized and unhybridized probe is required.

The damper is characterized by includ-ing a frame mountable to and extending above the chimney flue, a damper plate suspended from the frame, above and in alignment with the flue opening, by an expansion spring, and a vertical stern resiliently at-tached to the damper plate and extending downwardly therefrom.  The stem is mounted to the chimney flue so as to allow vertical movement thereof, and is con-nected by a cable to a control mechanism mounted in the fireplace opening.  The control mechanism, in co-operation with the expansion spring, allows selective movement of the damper plate toward and away from the flue opening to control or eliminate movement of air through the flue.  The resilient mounting of the stem to the damper plate allows the latter to pivot with respect to the stem, promoting a tight seal between the damper plate and the flue.

The font cartridge unit has a memory area divided into a plurality of page areas, and comprises memory groups consisting of ROMs and RAMS storing character pattern data in units of page areas.  A CPU sets a predetermined page address in a page address register in the font cartridge unit when dot printing of characters other than standard characters is performed.          The CPU reads out desired character pattern data from the page area of the memory group corresponding to the preset page address.  The CPU recognizes that no ROM is mounted at a position corresponding to the page area when predetermined data cannot be read out from the ROM.          The CPU writes the predetermined data in the predeter-mined page area, and thereafter, when the predetermined page area is accessed, if the predetermined data cannot be read out, the CPU determines that no RAM is mounted at a position corresponding to the page area.
