Abstract: 一种能够保持恒定信标周期、保证传送质量、并可靠地进行间歇接收的无线通信系统。无线通信管理设备将信标间隔信息传送到主信标和副信标。根据信标间隔信息，无线终端设备分割要传送的传送数据，使得在开始传送主信标之前完成传送数据的传送。因而，有可能防止信标和传送数据的传送定时的重叠，从而保证恒定的信标周期。因此，有可能保证传送质量、可靠地进行无线终端设备的间歇接收、并提高整个系统的数据传送效率。

The heater, Fig. 1 (not shown), comprises inner and outer wick tubes 5, 3 having a tubular wick 4 therebetween which dips into a fuel tank 1. The fuel trap comprises an impermeable membrane 9 which closely embraces the wick and is sealed to the tank. A perforated gallery 2 surrounds the outer wick tube 3 and is surrounded by a cone 8 and a chimney 7. The gallery 2 may be surrounded by a cylindrical wall which prevents burning fuel from leaving the gallery 2. In an alternative fuel trap, a tube surrounds the wick 4 and is sealed at the top and bottom to the tank, so that fuel must pass to the wick through perforations provided near the bottom thereof. The means for arresting outflow of oil from the chimney 7, Figs. 3-8 (not shown), may comprise an annular baffle, a circumferential trough, or a combination thereof. Drains may be provided in the chimney below the baffle or in the trough of a diameter which causes burning oil passing therethrough to be extinguished. The chimney 7 may be provided at its open end with a normally retracted plug urged to a closed position by a spring released by a catch in the event of the heater overturning. In the event of the heater overturning the burner flame may be extinguished by causing a reversal of the draught in the chimney, Figs. 10-12 (not shown). The draught may be reversed by providing the wick tube 5 with upwardly angled baffles or an annular baffle which is closed by a spring-loaded valve automatically released if the heater is overturned. Alternatively, the chimney may be provided with a coaxial inner tube.

The propylene polymer is either a homopolymer or contains up to 15 wt. per cent of units of other ethylenically unsaturated monomers, and the solvent may contain up to 15 wt. per cent of other materials. The solution is heated in an autoclave until the required temperature and pressure are reached, and is then passed into the spinneret shown in Fig. 2. The solution passes through the letdown orifice 12 into the letdown chamber 13 where it precipitates rapidly, and is then discharged through the orifice 14 into the atmosphere in a finely divided dispersed form. The solvent evaporates instantaneously and forms bubbles which break out of the polymer and leave a solid fibrillated strand. In order to reach the required solution pressure in the autoclave, nitrogen or other inert gas may be introduced, or pumps or pistons may be used. The resulting fibrillated strands have good continuity and uniformity and high tenacity (at least 1À0-2À0 g.p.d.).

Abstract: 1,225,959. Filing papers &c. KING JIM CO. Ltd. 14 July, 1969 [26 Sept., 1968], No. 35347/69. Heading B6E. A document holding clamp moulded integrally of a plastics material comprises a cover plate 1 provided with prongs 4 and articulated by flexible hinge members 7 to a base-plate 4 which is provided with sockets 5 co-operating with the prongs 4. Opening of the clamp is facilitated by provision of a co-operating brims 9 and projections 10, the brims 9 forcing the cover plate 1 upwardly when the prongs are released from frictional engagement with the sockets 5. The clamp may be attached to a filing folder along its spine or an upper marginal edge.
