Abstract: ABSTRACT OF THE DISCLOSURE      A curb marking gage having a generally L-shaped frame upon which are mounted a plurality of vertically oriented wheels adapted to roll over the top surface of a curb construction and a plurality of horizontally oriented wheels adapted to be roll-able over the side surface of the curb construction.  A depth marking assembly is adjustably mounted on the frame and incor-porates a vertical arm having a scale inscribed thereon for height gaging purposes.  A paint container mounts at the bottom of the scale and feeds paint peripherally outwardly to a circular brush which is arranged for rotation relative to the frame for curb marking purposes.  The paint container is pivotally mounted and spring biased to continuously urge the circular brush against the curb during all periods of use.

Abstract: ABSTRACT OF THE DISCLOSURE         Paneling of thin walled metal containers subjected to vacuum conditions after filling is minimized by pressurizing the container at pressures substantially above atmospheric pressure with an inert gas having low absorption in liquids. By imposing an internal positive pressure in the container of about 5 to about 25 psig with a gas such as nitrogen, metal containers having wall thicknesses of 6 mils or less can be utilized in hot filling operations without encountering paneling after the sealed container and its contents have cooled to room temperature.

Abstract: ABSTRACT OF THE DISCLOSURE           In the proposed high frequency tubular ozonizer one common housing contains several ozonizing elements, each of these elements having a high voltage and a low voltage elec-trodes, both embodied in the form of coaxially disposed pipes coated with a dielectric material on the side of the reaction zone and provided with a circulation liquid cooling.  The cooling efficiency of the high voltage and the low voltage electrodes is increased by providing a core fitted in the expanded portion of each of the high-voltage electrodes, whereas each low voltage electrode is made of two coaxially arranged pipes with the cooling liquid circulating between the pipes. The ends of the high voltage tubular electrodes of the ozonizing elements are secured in the walls of manifolds serv-ing as admitting and discharging conduits for the cooling liquid, whereas the high voltage electrodes are arranged coaxially of the low voltage electrodes and are centered with high precision. The ozonizers of the proposed design allow the output thereof to be increased 50-100 times, that is instead of 1-2 kg of ozone per unit per hour they permit the production of 50-100 kg of ozone per hour, or even more.  This drastically reduces capital investment required for the manufacture of high-power ozonizers.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to an article for increasing the life expectancy of filament light bulbs. It has been known to rewire electrical circuits feeding light bulbs to include conventional power decreasing and/or transient limiting devices therein.  However, because of the inconvenience of this approach, it has been used to an insignifi-cant extent.  Heretofore, there has been no simple and efficient way to insert convention power decreasing and/or transient limiting devices such as a diode in a home light bulb circuit.  The present invention overcomes these problems. According to the present invention, there is provided an article positionable in a conventional light bulb socket, which article includes a standard, conventionally packaged, power decreasing and/or transient limiting device, such as an axial lead diode, for decreasing by a factor of approximately two and for limiting the turn-on and turn-off transients from the power input to a filament light bulb inserted into the socket.

Abstract: RECOIL REDUCING AND PISTON SHOCK ABSORBING MECHANISM     ABSTRACT OF THE DISCLOSURE             A firearm recoil system that reduces the maximum recoil force felt by the shooter.  The recoil force applied to the shooter's shoulder is interrupted by tapping off explosive gases produced by firing a cartridge and directing the gases into a gas cylinder to actuate a piston rearwardly and at the same time provide a forward force to the firearm opposite to the rearward recoil movement of the firearm.  The rearward piston movement is slowed down by compressing air trapped within the cylinder and then venting the compressed air so that the remaining recoil energy in the piston is gradually phased out.  This results in a substantially lesser peak or maximum shoulder force.

Abstract: Abstract of the Disclosure An electric car has powered drive (and braking drive) controlled by controlling the current through n d.c. motor by means of an on-off chopper.  When the car is below a pre-determined speed the field coil of the motor is in series connection with the armature to achieve full field control.          When it is above the predetermined speed the field coil is changed-over to shunt connection to achieve weak field control.      The duty cycle of the chopper is controlled by the running state of the car in order that the field current after change-over from series to shunt connection nay become substantially equal to the value, thus suppressing the transient change of the current.

Abstract: ABSTRACT OF THE DISCLOSURE         A heat reclamation system particularly adapted to recover otherwise rejected heat from the refrigerant gas flowing through air-conditioning and refrigerating systems.  The appara-tus includes a counter-flow heat exchanger for transferring heat to a medium such as water, the heat exchanger being installed in the tubing between the compressor and the conventional con-denser.   A pump circulates water through one side of the heat exchanger.  Hot refrigerant gas from the compressor is circulated through the other side of the heat exchanger.  The various para-meters of the heat exchanger are chosen so as to remove the superheat of the refrigerant and also to partially condense the refrigerant to a degree such that the refrigerant, upon its emer-gence from the above-mentioned heat exchanger will be partially sub-cooled, but generally not to a level where the quality of the refrigerant will go below about 0.25.           The apparatus of this invention is readily adaptable for use as part of a new air-conditioning and refrigerating system or as an addition to an old system, of varying capacities, without adversely affecting their performance and reliability in other respects.  Moreover, it not only will permit efficient use of excess heat reclaimed from the refrigerant gas, but also will cause the air-conditioning and refrigerating system itself to operate more efficiently.
