Abstract: A grommet (150) is securable to and along an edge (46) of a wall (36) of an enclosure (10) to provide sealing about lengths of cable extending through recesses (48) along the edge (46). Grommet (150) includes a cable-receiving section (152) having a diaphragm (168) traversing each of the recesses and includes a virtual slit (156) extending from a thick top edge portion (154) and through the diaphragm to the thick bottom edge portion (158). A cable (22) is insertable into the virtual slit (156) until seated in and through the diaphragm; stiff opposed portions (176) of the top edge (154) of the grommet close after being deflected temporarily as the cable is urged therepast; thin resilient opposed strips (170) of the diaphragm (168) similarly close upon said cable being urged therepast, while strips (170) adjacent the cable remain deflected by and biased against the cable. Upstanding wall sections (50,52) of the enclosure wall (36) are received through apertures (164) through the grommet and latch therewith.

Abstract: An electrical component (10, 110, 210, 310) for electrically connecting insulated electrical conductors (56) thereto comprises a dielectric housing (12, 112, 212, 312) including a first housing section (20, 118, 218, 318) and a second housing section (22, 120, 220, 320), first and second electrical contact members (42, 44, 158, 160, 240, 242, 334, 336) disposed in the dielectric housing and having first contacts (42a, 44a, 158a, 160a, 240a, 242a, 334a, 336a) extending into the second housing section and second contacts (42b, 44b, 158b, 160b, 240b, 242b, 334b, 336b) positioned within the first housing section, insulation-displacement contacts (42a, 44a, 158a, 160a, 248, 348) as part of the first contacts along which the insulated electrical conductors are positioned, and conductor-moving members (16, 18, 154, 156, 250, 346) for engaging the insulated electrical conductors and moving them into the insulation-displacement contacts thereby forming electrical connections between the insulation-displacement contact

Abstract: A flame cover device for use with mechanical candle holders, especially for use with candle holders in which the candle is spring-driven to the top of a tube as the candle is consumed. The apparatus may be removably disposed upon the top portion of the tube of the mechanical candle holder, where it remains motionless while the candle is burned by combustion, yet provides protection from and to the burning flame. A base of the device is engaged with the tube of the mechanical candle holder, with vents in the base providing adequate ventilation to the flame. A transparent shell extends up from the base to provide flame protection. A ring damper is provided for covering the vents in the base to assist the flame in windy conditions.

Abstract: The invention is directed to a bus bar contact having a body with two mating ends. One of the mating ends has a tab contact portion. The other of the mating ends having a receptacle contact portion. The receptacle contact portion has a plurality of resilient fingers for providing an electrical interface. The resilient fingers are stamped and formed from the body member wherein adjacent resilient fingers are sheared from each other thereby removing no material from between the adjacent resilient fingers.

Abstract: An abrasive throwing wheel assembly comprises a throwing wheel having parallel annular side plates (29) joined by spacers with the facing surfaces of the side plates having angularly-spaced registering throwing blade locating slots (30) and throwing blades (20) with lateral rails or edges (22) for location in the slots. The side wheels slots are wider than is customary and contain central radially-extending projections (30c). The lateral rails or edges of the throwing blades are grooved (28) from the tips inwardly for at least part of their lengths. The throwing blades are located by interengagement between the sidewall projects and the rail or edge grooves of the blades. This reduces the surface contact between the blades and the side plates with consequent reduction in the accumulation of jamming abrasive during use. Throwing blade removal is thus facilitated.

Abstract: Nitrate-polluted run-off water from a field is conveyed via land drains to a reservoir. The reservoir is large enough to contain excess quantities of storm water from the field. From the reservoir, the run-off water enters a tank which contains wood or other organic carbon material. The wood is kept under water, i.e. under anaerobic conditions, whereby the nitrate is broken down by bio-chemical action. Sufficient wood is provided, and the flow rate is so adjusted, that the nitrate-polluted water spends many hours in contact with the wood.

Abstract: A blade for use in a blast impellor wheel for use in cleaning castings has both faces identical and symmetrical about its longitudinal axis so that both faces can be used as abrasive throwing faces. The blast impellor wheel comprises two interconnected parallel side plates each of which has a central opening. Opposed pairs of slots are provided in the inner faces of the side plates and these slots are transversely stepped so that protruberances on the side of a blade can abut against the ledges so formed.

Abstract: An apparatus is disclosed for removing molding sand from a cast part. The apparatus includes an open framework vibratory mechanism for causing movement of the molded parts through a tunnel-like member. This movement shakes and jolts the parts to loosen sand and free it from the casting. Also provided are particulate blasting means located at strategic positions in the tunnel enhancing removal of the mold sand.

Abstract: A packaged core is obtained using a conventional core barrel system. A lining is provided in the core sample container of the core barrel. The core barrel is connected to a drill string extending into a borehole. As the drill string is rotated, the core sample moves into the sample container and inside of the lining. When the core barrel arrives at the surface, the sample core may be removed from the core barrel packaged in the lining. The core may be examined on site or the ends of the lining closed and the core completely packaged for shipment to the laboratory.
