Abstract: An emergency exit indicator that will signal the location of an emergency exit by a high intensity smoke piercing light and audible alarm, becoming activated automatically when smoke reaches a predetermined level. This indicator is particularly useful in movie theatres, night clubs and similar places where it is necessary to utilize subdued exit lights that will not be distracting. In cases of emergency involving smoke, the emergency exit indicator of this invention becomes activated automatically, thereby emitting a powerful beam of light capable of piercing through substantial distances of dense smoke. However, when the indicator is not activated it will not cause a distraction.

Abstract: A color recognition system is used to distinguish between objects of various colors. A plurality of light sources are arranged at a sensing station to reflect light from the object as it passes the sensing station to a plurality of cooperatively mounted light detectors. The signals produced by the plurality of detectors are compared with a reference voltage and the comparison utilized to differentiate between objects of different colors passing the sensing station. In a particular embodiment of the invention, the color recognition system is incorporated in a ball separator for a pool table to separate the entirely white cue ball from the partially or wholly differently colored object balls and to divert the cue ball into a first storage station and the object balls into a separate storage station.

Abstract: A sports practice device for practicing the stroking motion used in games such as tennis, baseball, squash and the like includes a pair of guide rails mounted to the floor and ceiling of a room, a pair of carriages constrained to move relative to the rails between stops mounted in the rails, and a ball secured to an elastic cord which in turn is secured to the carriage members thereby suspending the ball a pre-determined distance above the floor at a hitting position. When the ball is hit, motion is imparted to the carriage members which move along the guide rails until their motion is stopped by the stops. The ball continues to move stretching the elastic cord which after full stretch snaps the ball back to its initial position.

Abstract: To defrost a selected evaporator, in a system including at least two evaporators, the system condenser is isolated from the compressor and the selected evaporator receives hot, compressed refrigerant vapor directly from the compressor. The liquid refrigerant formed in the defrosting evaporator flows to the other evaporators in the system to permit them to continue in the refrigeration mode. A pressure regulated control system is provided which causes excess liquid refrigerant in the defrosted evaporator to be pumped out of that evaporator before the evaporator is reconnected to the compressor suction line. In a preferred embodiment, each evaporator includes a coil having a plurality of circuits connected between its inlet and outlet and each circuit is disposed in a horizontal plane at a different elevation from any of the other circuits.

Abstract: This device intended for crack removing machines comprising a frame structure, a post and a first fluid-actuated cylinder connected to a two-armed lever pivotally connected to an arm supporting the grinding wheel comprises a third cylinder connected in parallel to the first cylinder and having one point of its cylinder and another point at the end of its piston rod pivotally connected the former about a vertical axis fixed in relation to the frame structure of the machine and the latter about another axis fixed in relation to the post and not coincident with the pivot axis of this post.

Abstract: A surface for mounting an item in a container is provided with clamping members which restrain the item against the surface. Each clamping member includes a frustum-shaped lug having a gripping portion on its periphery, and also has a resilient member for mounting the lug to the mounting surface so that at least a portion of the lug is movable in a generally perpendicular direction with respect to the mounting surface. In use, a plurality of clamping members are secured to the mounting surface so that their gripping portions engage the perimeter of the item when it is received on the mounting surface. With the item in this position, the clamping members restrain it against the mounting surface.

Abstract: The invention provides a sealing strip and a frame, for instance a door frame, for use therewith. The frame includes a groove, to receive the strip, which is integrally formed in the material of the frame and which is so positioned and orientated that the strip is retained in an optimum position for firm contact by, and sealing with a closure, such as a door, to provide a barrier against passage therethrough of moisture, foreign matter, sound and heat.

Abstract: A pressure responsive diaphragm has on its periphery axially spaced annular projections to define a peripheral annular groove therebetween which receives an annular projection at the coupling surface of a coupling flange. The diaphragm is thus releasably retained on the coupling flange and encloses a recess formed in the flange which recess communicates with the instrument. A compressible sealing ring for the recess within the flange is positioned on the peripheral surface of an annular projection of the diaphragm. The diaphragm may also be provided with an axially extending annular projection which is received in a corresponding axially opening groove formed in the coupling flange. A compressible sealing O-ring may be positioned within this axially opening groove radially outwardly of the diaphragm projection or may be positioned on the peripheral edge of the second annular projection of the diaphragm and arranged so that the O-ring contacts two or three metal walls of the coupling flange.

Abstract: Novel paint compositions which may be universally applied to a variety of substrates such as metals or plastics without the use of an intermediate primer layer are formed from a mixture of a polymerizable vinyl monomer, an epoxy pre-polymer, a urethane resin, a peroxide polymerization initiator and a silver graft initiator in a suitable solvent. Conventional paint additives are also included in the composition. A one-coat application of the paint followed by conventional oven curing results in a painted object in which the paint is chemically bonded to the object and exhibits superior chemical and mechanical properties.

Abstract: The present invention relates to a game of logic which matches the skill and strategy of one player against the other. This game includes a game board having a central display portion wherein a plurality of display devices such as electric lamps are activated by the actuation of the proper combination of switches in the control console at each player's end of the game board. Each switch at one player's console is dependently connected to the corresponding switch at the other player's console and to an electric lamp in such manner that either player can activate or deactivate each lamp in the central display portion of the game board. In play, each player attempts to activate the lamps on the central display area of the game board whereby patterns contained on any of a number of playing cards associated with the Game of Logic are duplicated in the central display area.
