Abstract: A device for catching cartridges ejected from a fired weapon. The device includes a fabric catch bag mounted on a frame and attached by means of a swivel mount to an extendable, base-mounted support rod. The frame may rotate about an axis parallel to the support rod or may pivot vertically. Cartridges ejected from a gun being fired adjacent to the bag will enter the bag and be contained therein, rather than falling onto the ground.

Abstract: Game apparatus (10) comprising a body (11) which has a perforated playing surface (13) and a border (14) upstanding from and extending around the playing surface (13), said border (14) having two opposite openings (15). Two flippers (16) are provided on opposite sides of each opening (15), which are pivotable by an operating mechanism (17). A motor-driven fan unit is provided under the playing surface (13) for driving air through the perforated playing surface (13) in order to create an air cushion thereon. A disc (19) is to be placed on the playing surface (13), while the fan unit is in action, for the flippers (16) at one opening (15) to strike to move into the other opening (15) and for flippers (16) at the other opening (15) to block against entry.

Abstract: An electric hair drier comprises a shallow housing 10 having an apertured boss 11 formed on its base. An electric motor 12 drives a thin cup shaped impeller 15 which in use draws air in through apertures 14 in the boss 11 and blows air radially towards a heating coil 17 surrounding inside peripheral surface 25 of the impeller 15. The impeller has external blades 26 which in use draw air from the inside peripheral surface 25 towards a central axis of the drier at the mouth of the drier. The drier has an array of comb members 20 at its mouth. The thinness of the impeller 15 and the inherent even distribution of air passing over the coil 17 provides a hair drier which can be much thinner overall, and hence more comfortable to use, and in which the air is effectively and evenly heated.

Abstract: The present invention provides an apparatus and method for monitoring vehicular impacts using magnetostrictive sensors. The apparatus includes at least one and sometimes a plurality of magnetostrictive sensors positioned about a motor vehicle at locations appropriate for detecting and measuring stress waves in the structure of the vehicle caused by a vehicular collision or crash. Signals from the magnetostrictive sensors are collected and analyzed in a signal processing system that identifies a severe crash condition and commands a restraint trigger control system to activate one of a number of vehicle occupant restraint systems. The magnetostrictive sensors are structurally simple and mounted to integral elements of the vehicle by adhesive or mechanical attachment. Use of such magnetostrictive sensors in place of more conventional sensors (e.g. accelerometers) provides the opportunity to recognize and react to impact conditions within a significantly reduced time-frame.

Abstract: A spray bottle which comprises a bottle body having a mouth around which an annular groove is formed and a spraying pump having a stem located through the mouth of the bottle body for pumping up and spraying out liquid contained in the bottle body. The spraying pump includes a press-knob incorporating a spraying nozzle provided at an upper end of the stem and a cap provided co-axially around the stem for locating the overall spraying pump in position upon fitting over the mouth. An O-ring is located in the annular groove for engagement with an inner side of the cap for sealing.

Abstract: A pen self-illuminating when being used is disclosed. The pen includes a barrel with an ink reservoir therein. The ink reservoir has a pair of opposed ears extending from a middle portion thereof and a first spring mounted on the pair of opposed ears. A clip is disposed on the barrel and a switch member is disposed on the clip. The switch member comprises a cover, a mercury battery, a conducting strip, a spacer and a lamp. The cover has an electropad and a terminal thereon. The electropad is connected with one electrode of the mercury battery. The lamp is connected between the electropad and the terminal. The spacer is disposed between the mercury battery and the conducting strip. The conducting strip defines a central opening therein, an elastic trip extending from a periphery defining the opening and a contact strip extending upwardly from a periphery thereof.

Abstract: A device for attaching to a doorknob and a method for attaching the device to the doorknob, the device comprising a body having two arms and an elongated handle member with a removed end and a near end, a pin extending from the body between the two arms, and fastener means for engaging the surface of the doorknob after the pin has been inserted therein for holding the body to the doorknob.

Abstract: An atomizer comprises an atomizing head having a spray nozzle, an assembly part mounted over the atomizing head, a fan mounted in front of the assembly part and driven by a motor inside the assembly part. The fan has a jet head, the jet head being provided at a center of the front of the fan. A delivery tube is connected between the jet head and the spray nozzle, the delivery tube is located by a cramp disposed on the frame of the fan. The fan comprises a frame disposed therearound, by which the delivery tube is guided and further comprises a hole defined beneath the frame, a first conduit and a second conduit. The first conduit is connected between the spray nozzle of the atomizing head and the hole and the second conduit is connected between the hole and the jet head of the fan.

Abstract: An adaptor mounting a drill stand on an I-beam comprises a base plate which is clamped to a flange of the beam by clamping arrangements. A table of the drill stand is then bolted to cross-members slidably mounted on the base plate. In another arrangement, the pillar of the drill stand 11 is fitted in a collar housing which is slidably mounted on a base plate. In yet another arrangement, the pillar of the drill stand is mounted on the flange of an I-beam by opposed jaws which are slidable along the pillar and locked in position by screws.

Abstract: A fastening belt includes a first end, a second end, a first side and a second side. A corrugation extends from the first side thereof near the first end and a plurality of holes are defined in the fastening belt near the second end. A plurality of teeth extends from the second side of the fastening belt and are located between the corrugation and the second end such that the first end of the fastening belt is utilized by overlapping the first end thereof on the second end thereof with the teeth inserted into the holes corresponding thereto.

Abstract: A chain consists of at least a pair of chain links, a pair of side plates mounted between the chain links, a chain roller composed of at least two rolling elements mounted between the side plates, and a rivet extending through the chain links, the side plates and the rolling elements, wherein the rivet is tightly fitted with the chain links and loosely fitted with the side plates and the rolling elements so that the side plates and the rolling elements can have a pivotable movement relative to the chain links and the rivet.
