Abstract: ABSTRACT OF THE DISCLOSURE          The improved system of the present invention comprises a plurality of electrically interconnected power modules, each module comprising a sealed pressure vessel containing a volume of hydrogen and a plurality of batteries connected in parallel and disposed in a removable rack. Each battery comprises a stack or pile of series connected metal-hydrogen cells.  Means are provided for recirculating the hydrogen in the vessel around and between the cells and for cooling the hydrogen.  The cooling operation for the modules may be carried out internally or externally of the vessel. A blower or the like may facilitate the recirculation of the hydrogen. The modules are series connected to supply a desired large amperage, for example to take care of peak load requirements for a commercial power generating station or the like.  The system is capable of rapidly absorbing power from the station during periods of low demand and rapidly releasing the power during peak loads so as to level the load requirements.  The system provides optimum performance over a long period of time at low cost.

Abstract: ABSTRACT OF THE DISCLOSURE A control system for a power driven operator for gar-age doors and the like comprising an operator control circuit having a DC voltage source operating as the power supply for an electronic flip-flop device responsive to successively applied input signals to alternatively establish circuits of opposite direction through a reversible electric motor; i.e. one actuation causes the motor to run in one direction and the next actuation causes it to run in the opposite direction. The operator is sub-ject to actuation by both a hard wired push button or an auxiliary device such as a radio receiver which is responsive to signals from a remote transmitter. The operator control circuit includes a feature which electronically prevents the simultaneous ener-gization of the reversible electric motor in both directions. A further feature is a provision for de-energizing the operator motor control circuit relays after a period during which no actu-ation occurs, or after an interruption of the line voltage, the interruption being caused by a thermal switch or by external means. Still another feature is a provision to energize external devices such as garage lights for a period following actuation of the motor control.

Abstract: ABSTRACT OF THE DISCLOSURE     Wood pulp is dried by contacting it with heated air and subjecting the air and pulp to turbulence in a dryer comprising relatively contrarotating members which intermesh on rotation so that dried wood pulp fibres are suspended in the air issuing from the dryer.  The heated air is produced by heating air in a burner to a temperature of from 300° to 600°C by burning a fuel in the air.     The dried wood pulp fibres are separated from the air and a portion of the air thus separated is recycled to the burner.  The air admitted to the burner comprises fresh air and recycled air, the proportion of fresh air being such that the heated air contacting the pulp has an oxygen content of less than 10 per cent by volume.  The use of recycled air reduces the risk of fire when drying the wood pulp.

Abstract: SELF-DEPLOYING CHIN SPOILER        FOR A VEHICLE                                         ABSTRACT                      The combination of a laterally extending bumper mounted on the front end of a vehicle and a chin spoiler mounted beneath the bumper, the vehicle bumper having an ornamental face bar and a reinforcement member concealed therebehind.  The chin spoiler comprises a support means fastened by conventional fastening means to the bumper re-inforcement and an airfoil.  The airfoil is contoured along its leading edge to complement the frontal contour of the bumper face bar.  A hinge means secures the airfoil along its rear edge to the support means rearwardly of the bumper rein-forcement.  Biasing means interposed between the support means and the airfoil normally biases the latter towards the under-side of the bumper face bar in a concealed position beneath the vehicle.  The hinge means provides a hinge axis extending laterally of the vehicle about which the airfoil is deployable. The biasing means resists such deployment until the speed of the vehicle reaches a predetermined velocity at which the air pressure exerted upon the upper surface of the airfoil over-comes the biasing force of the biasing means causing the air-foil to pivot downwardly to present greater frontal area to the air stream trying to pass under the vehicle.

Abstract: BLOOM, D. M. 1-5 CREATION OF F? COLOR CENTERS            Abstract of the Disclosure Production of F? color centers in alkali halide crystals with densities high enough for efficient use in lasers is achieved by a two-step, highly selective photoionization mechanism.  This mechanism is coupled with the use of suitable divalent metal ions as efficient and stable electron traps to allow nearly 100 percent conversion of F2 color centers to F? color centers.  The two-step photoionization mechanism comprises photo-exciting the F2 color center to the first bound state, which requires lower energy than the corresponding transition for F color centers, then photoionizing the F2 color center from the first bound state, and finally, capturing the electron thus liberated on the divalent metal ions.
