Abstract: A firearm enclosure for enclosing a firearm, such as a black powder pistol or rifle, and includes and elongated sleeve portion having an opening at one end into which the firearm is inserted. This opening forms a watertight seal and enclosure, preferably with a resealable closure arrangement. The other end of the sleeve is closed and receives the muzzle of a firearm. This end of the sleeve is enclosed by a material which, while being waterproof, offers little resistance to puncture by a bullet exiting a muzzle, thereby minimizing any deflection or loss of momentum of the bullet. Use of the enclosure protects the firearm during use from the elements such as rain, sleet, snow, fog, and external humidity.

Abstract: A compensating device which includes a weighted lever adapted to be selectively disposed in restraining relation to a trip arm of an electrical switch controlling member responsive to head pressure in a reservoir main for cutting in or cutting out reservoir filling pumps, and operating for selectively delaying pump cut-out.

Abstract: A balance beam adjustable for a desired liquid level in a reservoir is under the control of a device responsive to pressure head in a main leading from, and reflecting the liquid level in, the reservoir, the beam being in charge of a pump control for one or more pumps for activating the pumps when required when the liquid level drops in the reservoir, whereby to substantially maintain the liquid level. A timer-operated anti-stagnation or anti-icing control device is provided in association with the beam.
