Title: Spread-spectrum communication apparatus
Inventor: MIKOSHIBA NOBUO
IPC: H04B1/707
Filed: 1992-02-26
Abstract: In a spread-spectrum communication apparatus using convolvers 13, 40 as correlators, demodulating processes in a receiver apparatus using a carrier and a PN code are performed under a non-synchronous condition. Binary data is converted to FSK form, and multiplicatively combined with a biphase coded PN sequence at one of two frequencies. At the receiver, correlation spikes are produced by convolver 13 when one frequency is received, and by convolver 40 when the other frequency is received. Convolvers 13, 40 receive modulated reference PN codes provided by PN code generator 19 and oscillators 38, 38'. In another embodiment (Fig. 11B) a single convolver is employed whose modulated reference signal PN code frequency is switchingly selected between one of two frequencies. The outputs of the convolver(s) are processed by a comparing demodulator 45. <IMAGE>

Title: Propelled pyrotechnic decoy flare
Inventor: TOWNING JAMES NEIL
IPC: C06B27/00
Filed: 1992-09-16
Abstract: An aircraft launched pyrotechnic decoy flare (1) which comprises a pellet (2) configured with a cavity (4) which extends along a fore-and-aft axis (8) of the pellet (2) and is vented at its rearward end (12). Part of the external surface of the pellet (2) is covered with a casing (16) to prevent combustion of said part of the surface. The pellet (2) is made of a gassy pyrotechnic composition including an organic binder, and an oxidising halogenated polymer and an oxidisable metallic material which react with each other on ignition and emit infrared radiation. When the flare (1) is ignited the surface of the cavity (4) combusts and produces hot gaseous products which escape from the cavity (4) through the vent (22) thus propelling the flare (1) in a forwards direction. In this way the flare (1) can be propelled in the same direction as the aircraft to reduce the rate at which the flare (1) separates from the aircraft exhaust. The pellet at figure 1 may be combined with a further pellet comprising discrete pieces of gassy infra-red emitting pyrotechnics composition in a rupturable container. <IMAGE>

Title: Improvements in or related to cleaning aggregate materials
Inventor: TALBOT JOHN EDWARD
IPC: E02F7/06
Filed: 1993-03-08
Abstract: A vehicle for cleaning the aggregate material in a French drain or trench has a chassis (10) supporting tracks (14) for moving the vehicle along the drain or trench.

Title: A welding material for hard-facing
Inventor: IKEDA HIDEAKI
IPC: B23K35/30
Filed: 1995-04-10
Abstract: The material is to be hardened by a supercooling treatment after overlaying onto a cast iron base metal has a basic component composition which meets, in an overlaid condition, both a first condition and a second condition. The first condition is that a nickel (Ni) equivalent and a chromium (Cr) equivalent fall within that region to be defined in Schaeffler's structure diagram in which a difference in hardness before and after the supercooling treatment is a predetermined value or above. The second condition is that a starting temperature of martensitic transformation is a predetermined temperature or below. The components of the welding material are determined by defining in Schaeffler's structure diagram a region in which a difference in hardness before and after the supercooling treatment becomes a predetermined value or above, obtaining a target composition in which the Ni equivalent and the Cr equivalent fall within the region and in which the starting temperature of martensitic transformation is a predetermined temperature or below, and determining the composition of basic components such that the target composition is attained in an overlaid condition. <IMAGE>
