摘要:
A croquet wicket lighting unit to provide illumination in the vicinity of a wicket to facilitate playing the game of croquet under conditions of low illumination. Components are attached to a mounting plate 11 that straddles the wicket. The mounting plate universally and firmly attaches to any size or style of wicket by means of retaining straps 24 and friction pads 25 in combination with universal engaging slots 12. The illumination element directs an intense beam of focused light through a hole 13 in the mounting plate and onto the playing surface immediately under the wicket to clearly reveal the passage of a ball through the wicket. The illumination scheme also casts a larger area of more diffuse light on the playing surface immediately adjacent to the focus spot to reveal croquet balls resting therein and facilitate play around the wicket. Batteries contained in a battery holder 15, with an on-off electric switch 18, provide power through a resistor 16 to a light emitting diode 14 as the source of illumination. Light emitting diodes are selected with predetermined brightness and cone of focus to provide both intense and efficient lighting. Component selection, and design are such as to provide impact tolerance against the environment of mallet and ball strikes inherent in croquet play.

An infra-red remote personal alarm system consists of a portable transmitter unit (10) which is intended to be worn or to be manually carried by the user, and which is operable by the user at any particular location to transmit an alarm signal in an emergency and which is to be received by a central receiving station (41) so that appropriate action can be initiated in response thereto. The transmitter unit is electrically operable and includes means (15) for transmitting pulsed infra-red alarm signals which can be picked-up by an infra-red signal receiver at the location of the user, and then retransmitted as an oscillating electrical signal via direct wiring (38, 39, 40, 42, 43) to the central receiving station (41) as a warning signal indicative at location monitoring points (43, 44) of the location from which the emergency call has been made. By making the transmitter units capable of transmitting infra-red pulsed warning signals, and suitably designing the receiver units to recognize and to receive the pulse signals for conversion into electrical signals for onward transmission to the central control station, it is possible to obtain transmission units which are robust and reliable in operation. Test facilities are also provided to enable continuous monitoring of the operational status of the transmission units and the receiver units, so as to minimize the risk of initiated emergency action of the transmission units being undetected.

A method of fabricating a plurality of seat elements is provided. The plurality of seat elements are styled to have a range of styling features. The method includes a step of determining the range of styling feature by selecting characteristics of a middle ply of foam and/or the exterior ply of the trim cover and selecting a number and position of panels that are sewn to form the trim cover. The seat elements are fabricated on a common mold apparatus.

A takeout jaw for handling glass bottles includes a holder for both fixed and floating inserts. This design allows an insert to be in a fixed position when the insert is provided with a nominal thickness. When a floating insert of a lesser thickness is installed, the spring clip does not engage the floating insert, which allows the floating insert to move vertically or float. The takeout holder contains either type of insert within the pocket with retaining clips that engage chamfers formed on the inserts.

A frangible projectile (1) is provided which has a conical nose (5) with an included angle in the range 40-41 degrees. The conical nose (5) has a forward end (9) which is blunt. The projectile is made from a mixture of a metal powder and a thermoplastic resin of nylon 11. The metal is about 80% by weight and the projectile has a specific gravity in the range 2.35 to 5.7. The projectile exhibits desired ballistic characteristics for distances up to about 150 m and can disintegrate on impact with solid objects. In addition a projectile made according to the preferred embodiment and fitted in a 5.56 mm.times.45 mm military cartridge case (equivalent to a 0.223 inch Remmington case) charged with a propellant such as type AR2207 (by ADI Ltd.) in the range of 25-26 grains, exhibits particularly suitable characteristics for use in firing ranges.
