Abstract: A key cutting device (20), for replacement keys, having a key blank support member (30), a lever-actuated shearing punch (25) for the key blank, and a depth-gauging stop (33) for the support member (30); the shearing punch (25) is formed to provide an optional two-step (44, 46) cut on the key with a control stop (49) for limiting the stroke of the punch to one step or two steps, as desired, for creating different cuts on the key blank; a locking device (63) automatically moves into locking position with respect to the yieldably-actuated support member (30) to prevent its displacement when the operating lever (37) is manipulated for the key cutting operation.

Abstract: A constant pressure discharge nozzle having a pressure-responsive baffle head assembly for varying the size of the discharge opening in response to fluid pressure in the nozzle, and having adjustable stop means, controlled from the exterior of the nozzle, for limiting the pressure-responsive opening movement of the baffle head to selected positions intermediate the minimum and maximum pressure-responsive positions, while still permitting pressure-responsive movement of the baffle head between a selected intermediate position and the minimum flow position.

Abstract: A constant pressure nozzle having a pressure-responsive baffle head movable toward and away from a throat element so as to define a discharge orifice. The throat being movably mounted for retraction by external control means to a debris-flushing position, but means being provided to maintain the throat in a fixed position during normal operation of the nozzle.

Abstract: A heat exchanger unit comprising a particulate heat exchanging mass or pack consisting of mechanically immobilized particles having no more than 750 microns mean diameter and having a thermal diffusivity constant of at least 0.5 cm.sup.2 /sec at 20.degree. C., and compressively retained in an enclosure in heat transfer relationship to each other and to a fluid directed therethrough. Preferred materials for the particles are crystalline carbon, copper and aluminum. The pack may be in cylindrical form or planar form and may be contained within metal conduits or, for solar radiation, within a transparent or translucent enclosure. Interconnected units may be disposed in an array or bank to provide the desired quantitive degree of thermal transfer.

Abstract: A wire grip hose clamp is disclosed, adapted to be applied to a hose by a driving tool having a rotatable socket. The clamp is characterized by having incorporated therein a screw having a relatively long head which is received in said socket, and a base flange formed integrally with said head and of enlarged diameter whereby to provide additional bearing surface for the end of the socket. The base flange has a conical or chamfered surface. These improvements are designed to prevent or minimize any tendency of the socket to become disengaged from the screw during installation of the clamp on the hose. The screw, including the head and flange, are made by forging or cold heading.

Abstract: A hose cutoff device or tool is disclosed which is especially adapted for cutting lengths of hose for use in hose assemblies for automotive air-conditioning systems. The device or tool comprises a base which is provided with axially-spaced, axially aligned, tubes for the reception of the hose to be cut, and with a manually-operable handle which is pivotally secured to the base, and is provided with a cutter blade which is movable through the hose to sever the hose into desired lengths. The cutter blade is of unique design or construction, is removably secured to the handle, and can be quickly and easily replaced when worn. A guard is provided for limiting movement of the handle away from the base and for partially enclosing the cutter blade.

Abstract: A device or tool is disclosed for assembling the hose and fitting of hose assemblies used in automotive air conditioning systems. The device comprises means for supporting the hose and fitting in spaced axial alignment with each other, and means including a handle and linkage responsive to movement of the handle for causing toothed rolls to engage diametrically opposite sides of the hose and force the hose over the end portion of the fitting. The toothed rolls are mounted eccentrically of studs on the handle and linkage, so as to vary the spacing between the rolls to accommodate therebetween hoses of different diameter.

Abstract: A grommet seal is disclosed comprising a cup-shaped part or piece adapted to provide a substantially air-tight seal between a wire, rod or tube and a metallic panel or the like through which the wire, rod or tube passes, and a mating part or piece interfitted with said cup-shaped part or piece, and adapted to act in combination or conjunction therewith to improve or complete the seal. The parts or pieces are provided with tongues which are flexibly movable relatively to the wire, rod or tube, to accommodate the passage through the grommet seal of wires, rods or tubes of varying or different diameters or sizes.

Abstract: A discal diaphragm body with a plurality of radially stress-relieving full-wave annular corrugations and a plurality of circumferentially stress-relieving full-wave radial spokes. The spokes follow and conform to the annular corrugations and are integrated with them to provide dual stress-relief and enhanced sensitivity for a pressure-responsive diaphragm.

Abstract: A spiral meat slicer or ham slicer is disclosed in which a rotating circular or disk like blade is brought into contact with a rotating ham for the purpose of slicing the ham. Means are provided for causing the blade to be moved axially in relation to the axis of the ham, and for canting the axis of rotation of the blade slightly in relation to the axis of rotation of the ham, whereby to form a single continuous spiral slice from the whole ham. Means are also provided for preventing exposure of the blade when not in use, whereby to avoid injury to the operator of the slicer and others. Additional means are also provided for stabilizing the operation of the cutter or slicer unit, whereby greater efficiency in operation and use of the device, as well as an improved product, is attained.

Abstract: Hose clamps are disclosed comprising a band, band section, or attachment to a band, which yields in a direction circumferentially of the band and which possesses a spring-like quality and/or action such that the clamp is essentially self-adjusting to compensate for thermal expansion and contraction of the assembly (clamp, hose and fitting), as well as for the aging or cold set which the hose undergoes, whereby a fluid-tight seal is maintained throughout the intended life of the assembly, without requiring the clamp to be re-tightened. The bands of the clamps are open-ended and of generally circular configuration and are provided with a tangentially located or oriented worm drive screw for closing the clamp and providing a greater and closer range of adjustment in closing the clamp. The clamps, in some cases, have incorporated therein a positive stop, whereby closure of the clamp can be limited to a specified or predetermined size or diameter.
