An economical liner-free aluminum handle embodiment has reinforcement and scarring-preventing spacers adapted for press-fit assembly. Clip-on attachment and other structure provide plier sections. A container provides advantageous "T"-handle facility for boring with the system, protrusive head pivotal fasteners facilitate scraping operation, and novel storage provisions are described.

Abstract: A module of a filing cabinet houses in a pivotal-lid covered filing cabinet a pendent file. Four castors at respective corners retract upward into the housing for providing compact, fixed-location, vertically stackable storage of a plurality of such modules. With the castors extended a module can be drawn along behind the user at the end of a length of line, transporting heavy loads of documents held in the pendent file. A lever-powered spring-biased system actuated by lines holds the castors up-or-down as desired, and a key-lock may be used to secure the lid.

Abstract: Holding tanks in an extremely simple vacuum-sewage system can provide high volume storage against emergencies such as vacuum pump failure, while providing under normal circumstances frequent, sudden, small-volume discharges in which any one holding tank discharge may trigger one or more others as in a cascade sequence, precluding conditions that might produce septic accumulations. Each holding tank has a float valve with a float that can be held on the respective valve seat, against buoyancy by sewage, by conventional vacuum pumping of the main. When vacuum in the main is degraded by use of a special valve or switch for the purpose or by holding tank discharge, holding tanks are selectively discharged as a result.

Abstract: A portable locking system for hinged door improves on the type having a right-angle end of a first member for engaging a strike plate in a door frame and second member with a right angle end for pressing against the door and laterally and detachably engaging the first member. The detachable lateral engagement of this invention includes a series of holes tangential to each other in the first member and a plurality of juxtaposed pins protruding from the second member in position for adjustably engaging any corresponding selected holes in the first member. The system preferably includes a "U"-shaped keeper for holding the first and second members together for carrying them, or after installation. For identification in the dark and for ease in handling, a second angled-end of the hole plate is made longer than the first end. Similarly, one of the legs of the "U"-shaped keeper is made longer than the other.

Abstract: A wirestripper for thermal stripping a length of insulated wire includes a "V"-shaped flat metal strip of nickel chrome alloy 0.2 mm thick and having first and second arms 1 mm wide and 3.2 cm long extending from a vertex. The "V"-shaped strip is supported between a support post at the vertex and a respective electrode post at the end of each of the arms, with the electrode posts and support post being parallel and biased apart to tension the "V"-shaped strip. The electrode posts are spaced apart a sufficient distance to permit the length of wire to be stripped to be passed laterally therebetween and between the first and second arms into the vertex for stripping. The serial resistance of the "V"-shaped strip between the electrode posts sufficient for energization of the strip by a 1.2 volt battery connected to the electrode posts.

Abstract: A system for preventing debris from a sloping roof from clogging a gutter provides a panel of fine screening such as insect screening stretched taut between an upper margin cemented to a roof and a lower margin cemented to the outer edge of a gutter. A plurality of resilient tubular spacers in parallel downward array beneath the screening space it from the roof, causing water to flow through the screening and pass down the roof between the screening and roof. Water is retarded in the process, inhibiting overshoot of the gutter. Water may drop directly into the gutter at the lower border; the lower border is steeper in slope than other portions to shed debris better.

Abstract: A system for preventing accumulation of partially used fingernail finishing materials includes four disk-shaped containers, each with a capacity for containing one application of a nail finishing material of a set, such as nail polish, cuticle remover, ridge filler and top polish. A flexible holder has a cylindrical shape proportioned for holding four containers in coaxial relation, and a door-closable opening proportioned for fitting the containers so that the containers snap-fit through the opening. The containers have flexible handles on which the door presses when closed. A tree, that preferably is supplied in kit form, holds four containers comprising typically a one-month supply, one to an arm protrusive from the tree stem, which is fitted to a supportive base.

Abstract: A bump-actuable filament feed for vegetation trimmers; when the cutting length of filament breaks or wears short, the user without interrupting cutting simply bumps the cutting head on the ground deploying a fresh cutting-length of filament. Bumping causes a spring-restored spool latch to yield an increment of spool rotation, feeding a corresponding increment of filament from the spool. For replenishing the filament supply when exhausted, the spool snaps out in one embodiment on pressing a button, and a fresh spool as easily snaps into place.For applications in which bumping the cutting head against the ground is not desired an analogous operation is provided by adaptation of the basic structure.

Abstract: An electro-mechanical heart compressor system for use in rendering first aid in cases of heart stoppage provides a constant-stroke-length, motor driven reciprocating plunger extending downwardly through a first or upper mounting plate. A second or lower mounting plate with uprights at the ends provides a support for a patient and adjustably holds above it the upper mounting plate in position with the plunger above a mark designating the proper location for the patient's heart. The reciprocation is provided by an electric motor acting through a crank and slotted yoke adjustably affixed to the shaft of the plunger, which shaft is held in guides.

Abstract: A system for use in swimming pool construction for temporarily holding a rounded coping to a wall form during pouring of concrete, making the coping a permanent part of the swimming pool but permitting quick removal of the wall form, includes, at intervals, a lag screw rotatably mounted on the top of the wall form in position for the threaded pointed end of the lag screw to engage a vinyl liner slot in the coping, and when rotated to draw the coping against the wall form. To prevent the screw from "walking" in the slot when rotated and to assure coping level, an even coping line and straight wall construction, a coping alignment track on the wall form has a lateral protrusion fitted into the vinyl liner slot and length extending longitudinally of the coping from one lag screw to the next.

Abstract: A stove guard prevents small children from operating front-mounted controls of a conventional kitchen stove having an open door hinged at the bottom. The stove guard has a front panel portion for extending at a vertically outward angle across the front of a stove. The front panel portion is integral along a transverse lower portion with a horizontal panel portion that projects rearwardly from the transverse lower portion as a shielding bottom and a mount for the stove guard when a rear portion of the rearward projection is clasped between an oven wall and top of oven door, on closure of the oven door. First and second trapezoidal-shape end portions integral with the front panel portion and the horizontal panel portion close off access at the ends of the stove guard.

Abstract: An internal combustion power plant system provides a rotary engine and a rotary fuel/air mixture compressor for the rotary engine on a common driveshaft, coaxially mounting each end and supported between them by a gearbox which synchronizes operation of various ignition and valve and abutment components of the system; compressed fuel/air mixture is supplied to and ignited in a valve-isolated manifold chamber in the rotary engine in successive charges following which each ignited charge is valved radially into one of plural expanding chambers defined by the rotary engine rotor and abutment mechanism, where it urges rotation of the rotor and then exhausts radially; in preferred embodiment the exhaust actuates a parallel fuel-feed which booster pumps fuel/air mixture into the manifold chamber; detail improvements disclosed include designs of runners, abutments, valving and rotary compressor mechanism.

Abstract: An improved magnetic thermal generator has axially aligned, spaced-apart shafts, each with an electric motor at the outer end and on each inner end a permanent cylindrical magnet rotor with alternate north-pole and south-pole disposition of magnets parallel to each other in a circle about the shaft axis. In the spacing between the inner ends of the shafts a boiler is axially affixed. The boiler is of steel, is cylindrical in cross-sectional shape, and has at each end a steel disk-shaped end closure on the outside of which is bolted a copper disk of the same size. Fixed to the copper disk and extending hermetically through the end closure are a plurality of copper heat sinks, with axially alternative larger and smaller diameters; preferably the copper heat sinks from the respective ends are coaxially disposed and terminate within the boiler adjacent to each other but not touching.

Abstract: A rotary cutting and finishing head of the flail type can use common commercially available sandpaper or emery cloth or other sheet material. A hub of the type rotatable by drill press or hand drill, mounts, in plane, uniform length and width strips or ribbons of any of these materials on slotted tube posts coaxially fixed to the hub. Each slot is of a size to capture a fixed end of a respective ribbon on assembly. In one version, every second post is provided with a ribbon. The ribbons are then wound in a substantially circumferential direction in and out among the posts, the odd posts being merely supports for the staggered partially overlying ribbons. On rotation of the hub at high speed, when the flail end of a ribbon wears from flexing at a post, it may part and release a fresh length or flail end at adjacent location. Alternately, fresh lengths of ribbon may be deployed manually by cutting off or tearing off worn flail portions.

Abstract: A hand tool for sheet metal workers notches and soft-noses an end of a sheet metal drive in one operation, and saves time and prevents injuries as compared with use of tin snips to do the same job. Paired handles of the tool are held in one hand while, with the other hand, the end of a sheet metal drive is slid onto an upper plate and against a stop. The upper plate, a lower plate fixed to it, and a blade shaped to engage portions of the periphery of the upper and lower plates form a shear in which a lower plate fixed in parallel spaced relation to the upper plate serves to support a portion of the drive. Shape of the shear causes the drive to be notched and soft-nosed with a squeeze of the handles.

Abstract: A system for reducing wavelength error caused by angular motion of the moving mirror of an interferometer, such as a Michelson interferometer having fore-optics introducing a beam of radiant energy for impingement on the moving mirror, teaches reducing, without necessary loss of energy, the width of the beam before impingement on the moving mirror; other advantages also accrue to use of the reduced width beam, such as facility in use of absorption cells and multiplying clear path length, when desired.
