Abstract: ABSTRACT OF THE DISCLOSURE The game playing apparatus disclosed herein employs an array of essentially transparent finger contact sensors and, under-lying said sensors, a corresponding array of solid state light sources.  The sensors and the light sources are independently connected to electronic circuit means, including a digital processor and a readable memory store, so that each of the light sources can be energized independently of the actuation of the respective sensor.  Light sources are energizable in either of two states, a blinking state and a steady state.  The processor, operating under instructions contained in the memory store, establishes overall light patterns on the light source array in response to sequences of actuations of the sensors.  In addition to generating light patterns, the processor preferably also controls sound generating means for interaction with a game player.

Abstract: ABSTRACT         In the manufacture of a flexible, laminated composite body, a perforated film of shrinkable, thermoplastic material is fed over a guide path, which is continuously curved in one direction and heated by a heating means to the thermoplastic condition.  With the shrinkage of the thermo-plastic material, a net structure forms when the perforations open up.          Using the heat still present from the shrinking step, a carrier web of material on one side of the net structure is bonded, with the aid of the net structure, to another web of material by a pair of pressure rollers to form a composite body.  By means of the curved guide path, an auxillary clamping of the perforated film takes place, by which the inward shrinkage of the peripheral zones is substantially reduced.  Following adhesion, the net structure extends substantially right up to the edges of the webs which it is used to bond together so that there is a uniformly strong adhesion over the whole working width.  The net structure may be bonded only to the carrier web where it is not desired to bond the other web to the structure at that time.

Abstract: ABSTRACT OF THE INVENTION     EXPOSURE CHAMBER    A chamber for exposing animals, plants, or materials to air containing gases or aerosols is so constructed that catch pans for animal excrement, for example, serve to aid the uniform distribution of air throughout the chamber instead of constituting obstacles as has been the case in prior animal exposure chambers.  The chamber comprises the usual imperforate top, bottom and side walls.  Within the chamber, cages and their associated pans are arranged in two columns.  The pans are spaced horizontally from the walls of the chamber in all directions. Corresponding pans of the two columns are also spaced horizontally from each other.  Preferably the pans of one column are also spaced vertically from corresponding pans of the other column.  Air is introduced into the top of the chamber and withdrawn from the bottom.  The general flow of air is therefor vertical.  The effect of the horizontal pans is based on the fact that a gas flowing past the edge of a flat plate that is perpendicular to the flow forms a wave on the upstream side of the plate. Air flows downwardly between the chamber walls and the outer edges of the pan.  It also flows downardly between the inner edges of the pans of the two columns.  It has been found that when the air carries aerosol particles, these particles are substantially uniformly distributed throughout the chamber.

Abstract: OSCILLATOR HAVING LOW NOISE SIGNAL EXTRACTION CIRCUIT          Abstract of the Disclosure A method and apparatus for minimizing the noise component of the output signal from a resonator oscillator. A single transistor or Darlington pair of transistors in the common base configuration is placed in series with the crystal resonator of the oscillator with a selected output load impedance connected between the base and collector of the transistors. By making use of this configuration, it is possible to use the crystal resonator as an initial filter to minimize the noise component of the output signal contributed by the oscillator loop as well as minimizing the inherent noise component from the output buffer ampli-fiers in the output signal.  A common base configuration of both of these embodiments provides a low impedance load on the oscillator loop thus minimizing the effect on tuning or Q of the oscillator while making it possible to select an output impedance load that is of sufficient size to present an output signal having a sufficiently high signal to noise ratio to provide the minimization sought.

Abstract: UNIVERSALLY ADJUSTABLE LAMP FIXTURE            ABSTRACT OF THE DISCLOSURE     A universally adjustable lamp fixture includes a separate base plate, light shield and lens assembly.  The shield and base plate are releasably connected together to permit the single base plate to be connected with shields having different shapes, depending on the use to which the lamp fixture is to be applied.  The shield is rotatable with respect to the base plate which, when a non-symmetrical shield is used, provides control of the orientation of the light patterns.  The lens assembly includes a rotatably mounted lens having an engagi socket formed therein to permit it to be rotated by a complemen-tary formed key.  This permits control of the light pattern even after the lens has become too hot to safely touch.

Abstract: A TOOL AND METHOD FOR TERMINATING ELECTRICAL        CONDUCTORS IN CONTACT MEMBERS                     ABSTRACT The present invention is directed generally to solderless electrical connections and, more particularly, to a novel tool and method for terminating a conductor into a portion of an electrical contact premounted in an electrical connector. Prior art solderless, insulation piercing connectors are available, but such con-nectors tend to develop high contact resistance, especially if the conductor is an insulated con-ductor having a stranded wire core.  The high con-tact resistance results from the tensile forces applied to the conductor when its insulation is pierced as well as from cold flow of the insulation surrounding the core which permits the individual strands to move with respect to the insulation-piercing contacts.  This problem with prior art connectors is solved according the disclosed tool and method for terminating conductors wherein the conductor is inserted into a contact and elec-trically engaged with at least one conductor engaging element of the contact and simultaneously portions of the contact other than the at least one conductor engaging element thereof is crimped onto the conductor to mechanically retain the conductor in electrical engagement with the con-tact member.  The contact may be premounted in an electrical connector assembly prior to termi-nating the conductor.

Abstract: ABSTRACT OF THE DISCLOSURE        A distance R to be measured is derived by measuring the spacing xm between a fixed transmitter Tx and a movable receiver Rx, and comparing this with the reference spacing xref between a fixed transmitter Tx' and receiver Rx.  Each spacing is measured by passing a large number of pulses sequentially from receiver to transmitter through a coupling medium, the receipt of one pulse triggering transmission of the next.  The spacing is derived from the time T taken to pass n pulses; preferably n is fixed and T is measured.

Abstract: ABSTRACT        The invention relates a process for preparing concentrated sulfuric acid by conducting a gas stream containing SO3 and H2SO4-vapour in a sulfuric acid tower in countercurrent to liquid sulfuric acid formed through a concentrating zone containing filler bodies trickled with sulfuric acid and an absorption zone where sulfuric acid vapour is absorbed in recycled sulfuric acid on filler bodies trickled therewith. A very substantial reduction in the amount of acid mist formed in conventional processes of this type is obtained by maintaining such temperature conditions in the tower that the recycle acid is withdrawn from the tower at a temperature T4 determined by the formula T4 >  140 + 6.alpha. + .beta. + 0.2(T1-Td) where .alpha. is the concentration of SO3 + H2SO4 vapour in the inlet gas to the tower, .beta. the concentration of water vapour in the same inlet gas, T1 the temperature in °C of the same inlet gas and Td the dew point of the sulfuric acid vapour in the same inlet gas. She filters to catch  cid mist may be smaller and they will only cause a very small pressure drop. The dimensions of the tower may be diminished to produce the same amount of concentrated sulfuric acid.
