Abstract: A cable lock for doors in which a loop at one end of a cable is attached by a bolt or screw to a building wall adjacent to a door and a larger loop at the opposite end of the cable is applied over and around a doorknob to limit the extent to which the door may be opened. In one embodiment of the lock, a metal sleeve encircles the major portion of the cable between the end loops. The metal sleeve increases the resistance of the device to cutting by bolt cutters, saws, and other burglary tools. A sleeve of resilient material encircles at least part of the cable between the end loops and serves to protect the door and door frame from damage upon contact of the cable therewith.

Abstract: A multi-function valve device for controlling the operation of a pneumatically-driven motor. A spring-biased linkage couples a cam-operated push pin to a valve spool assembly. The valve spool assembly coaxially combines the movable elements of a pressure regulator valve, a run valve, and a park valve into a single unit slidable axially within the valve housing and positioned by the spring-biased linkage. The pressure regulator valve permits an increasing pressure to be applied to a slowed or stopped pneumatic motor, approaching the pressure of the pneumatic source to aid in restarting the motor or to provide the additional force necessary to drive a heavily loaded motor. Automatic park and shutoff functions are also provided.

Abstract: A bag clamp assembly for a liquid filter wherein the clamp part of the assembly includes a cap and ring secured together by lock parts. The filter bag of the assembly is clamped between the rim and the cap to form a liquid-tight seal about the opening edge of the bag.

Abstract: An electrostatic air cleaner wherein the collector plates are uniquely constructed and are thus adapted for cleaning by a scraper. One embodiment uses two separate base members each having multiple spaced plates projecting perpendicularly therefrom. The base members are spaced with each plate of one base member being interposed between and spaced from adjacent plates of the other base member. The base members are shiftable between a use position and a cleaning position. Scrapers are mounted on each base and engage plates mounted on the other base member whereby shifting of the base members from their use position to cleaning position draws scrapers along both sets of plates to clean debris therefrom. Another embodiment includes two spaced apart parallel shafts, each of which carries multiple spaced circular discs. The discs of one shaft are interposed between and spaced from those of the other shaft. The shafts are journaled to rotate the discs through an air stream where they collect debris.

Abstract: A valved discharge member for use with the water supply system for use with cages of fowl and small animals, wherein a valve element in the member engages two spaced valve seats and is unseated by movement laterally and upwardly of a pin extending through a discharge opening and projecting below the housing.

Abstract: A release device for aid in drawing and quickly releasing the string of a bow to facilitate accurate launching of an arrow. A manually shiftable member is carried by the housing. Said member has a cam projection which is positionable between the jaw legs for retaining the jaws in string retaining position during drawing and aiming. The member is pivotable to remove the cam projections from the jaw legs to permit a spring to separate the jaw legs and to release a bow string.

Abstract: A reciprocating piston fluid powered motor providing great flexibility in its mounting and the location of the motor shaft and fluid inlet lines. Relatively few component parts are employed and a number of the components are used as-cast or with minimal machining operations required.

Abstract: A hinge assembly for a filter housing cap. The hinge assembly also serves as a hold-down for the cap. With securing devices loosened, the cap may be lifted from its closed position and remain connected to the housing.

Abstract: A method of and apparatus for compacting backfill in pipe and sewer trenches. A trench is filled with earth after the pipe is laid and an open ended tube is vibrated and lowered endwise into the backfill overlying the pipe while the pipe is substantially filled with water. The apparatus utilizes a vibrator carried by a backhoe and an open ended rigid tube suspended from the vibrator.

Abstract: A method of stuffing an aerated expanded flexible filler into a snug fitting cover, wherein air is evacuated from the filler while resting upon a support so as to shrink the filler and permit rapid application of the cover thereto. The apparatus includes a cantilevered chambered support with multiple openings in its filler supporting surface and selectively operable means for withdrawing air from the chamber and an air impervious sheet draped over the filler and the support.

Abstract: A baffle for use in an alcohol still. The baffle is provided with a concentric series of openings spaced and arranged to accommodate substantially even dispersement therethrough of steam at required temperature and pressure. Ribs on the baffle enhance uniformity of flow through openings throughout the baffle.

Abstract: A pair of doors hinged to a frame and including a self-locking three-point latch and coordinated closing system.

Abstract: A slitter having multiple spaced pairs of arbors supported for pivotal movement upon a frame. A drive located adjacent the pivot axis of the pairs of arbors is provided to make driving contact with one arbor of each of the arbor pairs as such pair of arbors is brought into and positioned across the passline of the slitter.

Abstract: A sponge mitt is covered with an abrasive surface material. The mitt is composed of a sponge material covered with a piece of woven, knitted or mesh material. The mitt is used wet to treat and smooth a joint between plasterboard drywall building panels.

Abstract: A high frequency battery charger operable from a 120 volt AC line power source which is rectified and converted by a blocking oscillator into 20-200 Khz rectified output for battery charging. A sensor for determining full battery charge serves as a power cut off to the battery with provision, if desired, for continued trickle charge of the battery.

Abstract: A method and means for anchoring a dismountable building by means of earth penetrating members. The building includes frame members which bear upon perimeter plates having ground piercing parts. Elongated ground anchors project through openings in the perimeter plates and are secured to the plates. A flexible sheet spans the ground on which the building is erected and is pierced by the elongated anchors and the ground piercing members of the perimeter plates.The method of anchoring the building entails the steps of spreading a sheet at a desired location, advancing auger type anchors into the ground through the sheet at points indicated on the sheet, placing on the sheet at positions indicated thereon perimeter plates with openings fitting over projecting portions of the anchors and with spike portions thereof piercing the sheet and penetrating the ground, and securing the perimeter plates to the anchors.

Abstract: A quick acting suspension means for smoke ejectors. Two opposed spring biased hooks are pivotally connected to a handle. The upper edges of the hooks are so shaped and positioned that, when pressed against a trim or frame member above a door or window opening, the hooks separate to pass around the frame member and then engage and anchor upon the frame member above the door or window opening. The handle unit of the suspension means is connected to a smoke ejector housing to facilitate convenience and ease of handling and suspension of the ejector by an unaided fireman.

Abstract: An improved fluid filter housing and filter bag seal wherein the filter bag includes an annular downturned lip of flexible, shape-retaining material which in part defines an opening into the bag. The housing carries an annular rim in part defining an opening into the housing. The bag lip is forced into sealing engagement with the housing rim by the housing cap to form a fluid-tight seal.

Abstract: A building panel of a layered design with textured inner and outer layers separated by a core to form a wall unit. The inner and outer layers are composed of a mixture of urea-formaldehyde resin, water, plaster and a curing agent. The core is composed of similar materials with an insulation material added.
