The manifold comprises a body portion (31) having at least one initiation port (32) for receiving an initiator device and at least one coupling flange (38) mounted on the body portion for engaging the expansion member and having a flange bore (40) for receiving the detonation fuse (16), the flange bore (40) being in detonation communication with the initiation port (32). The coupling flange (38) has in cross section an oblong configuration having a major axis and a minor axis and is dimensioned and configured so that the containment tube (20) can be flared for receiving the flange without significantly deforming the oblong configuration of the containment tube (20).

Abstract: A coupling device (10) for coupling a detonator cap (22a, 22b) with a detonating cord (82) features a sleeve member (12) having a longitudinal bore (18) extending therethrough for receiving a detonator cap (22a, 22b) in one end and a detonating cord (82) in the other. The coupling device (10) includes a nut member (14) having an aperture for receiving the cord (82) and having a compression surface (34) for bearing against a compression portion defined below when the nut member (14) is secured onto the sleeve member (12). The nut member (14) may be secured to the sleeve member (12) with its aperture aligned with the bore (18). A compression portion (31) associated with the sleeve member (12) responds to pressure from the compression surface (34) of the nut member (14) for gripping a cord (82) when the nut member (14) is secured onto the sleeve member ( 12). Thus, a cord can be securely disposed in detonation signal transmission relation to a cap without having special coupling hardware, e.g.

Abstract: An igniter (18) provides rapid longitudinal and radial propagation of the ignition reaction. The igniter may comprise a pyrotechnic material and an inorganic binder, such as silica, carried on a carrier web (10) which may be fiber-glass. One or more layers of coated web (10) are disposed to provide an igniter (18) of cylindrical configuration and having a hollow core. The coated layers are permeable to the ignition reaction to facilitate radial propagation of ignition. The hollow core and the continuous nature of the pyrotechnic layers promotes longitudinal propagation of ignition. The igniter may consist mostly or entirely of inorganic materials to reduce or eliminate the formation of carbon monoxide upon ignition, and may be contained within a radially perforated sheath (20) to form a radial ignition device (25).

Abstract: A forced air furnace (11) has a heat exchanger (35) with one or more tube pack assemblies (10). Each tube pack assembly (10) has a burner (21) situated to fire into a primary fire tube (30) which is mechanically connected through a transition cap (36) to a plurality of secondary tubes (37, 38, 39, 41) returning combustion products from the primary fire tube (30) to a collection manifold (24) at the intake end of a draft inducer assembly (23) for discharge of the combustion products to a flue. In the preferred embodiment, the transition cap (36) is connected to the primary fire tube (30) and to the secondary tubes (37, 38, 39, 41) by a mechanical interlock.

Abstract: An aerosol-dispensable foodstuffs parting composition for coating cooking surfaces comprising a water-in-oil emulsion containing natural lecithin, refined lecithin or a chemically modified lecithin selected from the group consisting of acylated, preferably acetylated lecithin, hydroxylated lecithin, and acetylated-hydroxylated lecithin, or mixtures thereof; an edible oil; an emulsifying agent; water; and a pressurized, normally gaseous propellant suitable for discharging the composition as an aerosol spray. A procedure for preparing the water-in-oil emulsion comprises mixing together the aforesaid ingredients except the propellant with about 7 to 21% of the total water, to form a concentrate. The remainder of the water and the propellant are added later. The emulsion may also contain one or more of a humectant, a suspending agent, a release agent and a blocking agent.

Abstract: A board press (10) comprises a dog member (12) dimensioned and configured to grip a joist (14a) and a lever (16) attached to one end to the dog member (12) by a ball and socket mounting (18) for pivoting of lever (16) about a pivot axis P--P. The ball and socket mounting (18) enables the pivot axis to be angularly displaced about a point on pivot axis P--P, thereby permitting the user to pivot the lever (16) perpendicularly to the edge (27) of a board (26a) being pressed despite twisting of the dog member (12) on the joist (14a) during use. A method of pressing one or more boards disposed on a joist includes using the board press and pivoting the lever in a pivot plane which is kept perpendicular to the edge of the board while simultaneously twisting the dog member to seat it upon the joist.

Abstract: A riding toy mechanism which provides both lateral and vertical reciprocating motion in which the amplitude of the vertical reciporcating motion is not determined by the amplitude of the lateral reciprocating motion. The mechanism includes a slide member (20) slidably mounted on the mechanism, a pivot member (24) pivotably mounted on the mechanism, and dual reciprocating means (28) for imparting harmonic lateral reciprocating motion to slide member (20) and independent vertical pivoting motion to pivot member (24). Dual reciprocating means (28) may include a cam (30) mounted to pivot member (24), a drive gear (31) for rotating the cam (30), and a connecting rod (32) pivotably and eccentrically attached at one end to one of the cam (30) and the drive gear (31) and at the other end and to mooring means (17). The mechanism includes cam follower means (40) upon which cam (30) rests.

Abstract: A connector system for providing electrical connection between two mutually opposed arrays of circuit contact pads including a housing (26) having an array of cells (30) corresponding to the arrays of circuit contact pads, with each cell containing a resilient connector element (21). Connector elements (21) are formed from connector blanks (10), each having a bow-shaped body portion (12). The body portion establishes a connector axis (20) and terminates at its opposite ends (14a, 14b) in respective first and second flag members (16a, 16b) which extend axially away from the body portion in respective opposite directions and terminate in electrically conductive contact surfaces, (17a, 17b, 18a, 18b, 56) to establish conductive contact with the circuit contact pads. The body portions (12) are disposed in a serpentine, single layer configuration defining an interior region into which the flag members radially extend.

Abstract: A parting composition for cooking foodstuffs includes a release agent which is a phosphate salt derivative of mono- and di-glycerides of edible fats, oils and/or fat-forming fatty acids, together with an edible oil and a pulverulent blocking agent. The edible oil may be any suitable vegetable or animal oil or shortening, and the blocking agent may be any edible clay, magnesium aluminum silicate, sodium bicarbonate, baking powder, ground limestone, calcium carbonate, calcium or magnesium stearate, flours or edible starches. For example, the blocking agent may comprise cereal flour or cornstarch, or a pharmaceutical kaolin, a food grade benetonite, calcium carbonate, or a mixture of two or more thereof. Preferably, the release agent is a mono-sodium glyceryl oleate phosphate. The composition may also include one or more of water, a suitable suspending agent such as fumed silica, and ethanol; a pressurized hydrocarbon propellant may be added when packaging the composition in a pressurized aerosol container.

Abstract: A dual piston rotary pump (10) having a housing (12) equipped with two ports (13a, 13b) to accommodate fluid flow through the housing (12) and having two generally cylindrical chambers (14a, 14b) within which cylindrical pistons (16a, 16b) are disposed. The chambers (14a, 14b) intersect to form a passage (15) therebetween and to allow the pistons (16a, 16b) to engage in tangential contact. Each piston (16a, 16b) rotates within its chamber (14a, 14b) in a direction counter to the direction of the other piston while maintaining tangential contact with the other piston and at least one piston is in tangential contact with its chamber wall. The pump includes variable offset transmission means (52a, 50a, 48a, 54a) to change the offset of the center of the piston from the center of rotation of the piston during the course of each rotation to allow the pistons (16a, 16b) to remain in mutual tangential contact at all times.

Abstract: An outlet chute (10) for a blower device to guide the expulsion of leaves, grass or other debris, having an inlet portion (26) and a bifurcated outlet portion (28) including a first outlet duct (30) and a second outlet duct (32) which direct debris in opposing lateral directions. A deflector vane (34) is disposed within bifurcated outlet portion (28) to deflect expelled debris to one of the first outlet duct and second outlet duct. The first outlet duct (30) allows for the expulsion of debris in substantially the same direction in which it leaves the blower housing and is configured to expel the debris closer to the ground than second outlet duct (32), which expels debris with less thrust and at higher elevation. A method of using a blower device equipped with the chute includes making a series of parallel passes with each pass in a direction opposite to that of its adjacent passes.
