Abstract: A pad for use with a hockey stick having a handle and a blade includes a generally flat pad element capable of covering at least a portion of a side surface of the blade. An adhesive layer securely affixes the pad element to the blade. The pad element is securely affixed to a side surface of the blade such that at least a bottom edge portion of the blade is not covered by the pad element.

Abstract: A game has a pair parallel walls defining a space therebetween, at least one of the walls being transparent to permit viewing of the space from the exterior of the game, and a liquid-light seal around the space, with a liquid retained in the space by the seal. Buoyant balls immersed in the liquid include a ferrous material, and a retainer extends partially across a lower portion of the space for releasably retaining the balls. A magnet at the exterior of the space is manipulable for displacing the balls from beneath the retainer; and ball receptacles located above the retainer each have a downwardly facing ball reception opening dimensioned to receive the balls therein as the balls rise buoyantly through the space on release of the balls by the magnet.

Abstract: A roof shingle has parallel top and bottom marginal edge portion which are turned inwardly of a central area and are interengageable with like bottom and top marginal edge portions, respectively, of like roof shingles. The shingle further comprising, at each side thereof, an upper side marginal edge portion and a lower side marginal edge portion, which are inclined relative to said parallel top and bottom marginal edge portions, respectively, so as to converge with one another; and are interengageable with like lower and upper side edge marginal portions, respectively, of like roof shingles.

Abstract: An ear irrigation device has a pump communicating with a water container for pumping water through a tube to a handpiece nozzle, for discharge into a person's ear. A control circuit operated by a switch energizes a motor, for driving the pump. The control circuit generates pulses to intermittently energize the motor, and the pulses are automatically controlled so as to positively restrict pressure discharge of water from the nozzle to a low pressure on actuation of the switch and subsequently to permit an increase in the pressure of the water discharge only after a predetermined time interval.

Abstract: A method of forming an object includes depositing a flowable material onto an area of forming surface and allowing the deposited material to at least partially harden on the forming surface to form a portion of the object, and then displacing the forming surface relative to the portion so as to expose at least a part of the area. Further material is then deposited onto the exposed area and above steps are repeated until the object has been formed.

Abstract: A screen printing machine has a bearing supporting a first arm structure for rotation about a vertical axis, the first arm structure comprising first arms equiangularly distributed about the vertical axis and extending radially outwardly of the vertical axis. The first arms each carry, at a free outer end thereof, a printing screen support platen. A second arm structure has second arms equiangularly distributed about the vertical axis and extending radially outwardly of the vertical axis, the second arms each carrying, at a free outer end thereof, a squeegee mechanism and a printing screen support for holding printing screen below the squeegee mechanism.

Abstract: In a method of and apparatus for accelerating and pressurizing a fluidized stream of particulate material, e.g. for blast cleaning by ice particles, the stream flows through a constriction in a flow passage. A flow of blast medium is discharged from a blast nozzle at supersonic speed into the fluidized stream so as to form within the fluidized stream a flow front which is impenetrable by the fluidized stream and which co-operates with the constriction to form an effective nozzle for accelerating the fluidized stream. Grounding is provided controlling electrostatic charges for either better work effect or neutralization in unwanted or hazardous conditions, and safety pressure relief, blast intensity control, articulation and changement of final nozzles for effective operation are also provided.

Abstract: A sheet metal slope and skew hanger connector has first and second side support members located at opposite sides of a backplate and being bendable relative to the backplate. Each of the side support members is formed with a pair of parallel ribs extending along a marginal edge portion thereof and with nail holes in each of the ribs to facilitate nailing of the connector to a first wood member, the nail holes extending through the connector at laterally outermost sides of the ribs. The connector includes a seat base extending from a bottom portion of the backplate for supportingly engaging an underside of a second wood member, with a pair of seat sides extending from opposite sides of the seat base, and a pair of tab members spaced apart from one another with a portion of the backplate therebetween, with nail holes in the tab members to facilitate nailing of the tab members to the opposite side faces of the second wood member.
