Title: Latched accumulator fractional n synthesis with residual error reduction
Inventor: ALEXANDER W HIETALA
IPC: H03L7/183
Filed: 1992-04-29
Abstract: A latched accumulator fractional-N synthesizer having reduced residual error for use in digital radio transceivers is disclosed. The divisor of the frequency divider (103) of the synthesizer is varied with time by the summation of accumulator carry output digital sequences which result in frequency increments equal to a fraction of the reference frequency. The accumulators (615, 617) are latched such that upon the occurrence of a clock pulse, data is transferred through each accumulator one clock pulse step at a time, such that the delay through the system is equal to that of only one accumulator. The latched output of the second highest order accumulator (619) is subtracted from the latched output of the highest order accumulator (621) and differentiated before being applied to the loop filter (109). <IMAGE>

Title: Rapid clothing manufacture
Inventor: JOHNSON KEITH DAVID BEBB
IPC: D04H1/64
Filed: 1993-03-19
Abstract: A process for the rapid manufacture of clothing, e.g. panties and bra, by mass production techniques is based upon the use of a body-form 10 which is hollow, but has walls which are in part polished and impermeable 11, and in part porous 13. The porous parts correspond to the shape of garments which are to be made. Suction can be applied to the space within the body-form via a tube 20. By placing the body- form into one or more vessels filled with a fluidised bed of fibres and fluids, and applying a suction pulse or pulses to extract an appropriate volume of fluid, fibres are deposited as a mat of appropriate thickness upon the porous areas. Thereafter the mat is subjected in a separate vessel (43) to a tacking process which joins fibres to each other and converts the mat into a fabric. The tacking process may utilise laser beams, a spray of flexible bonding agents, heating, or electrostatic attraction of droplets of chemically active adhesive. The body-forms are recycled and reused using them in train on a track 25. Variations of detail enable the articles of clothing to be of different forms, of different sizes, of different and varied thicknesses (14) or with patterns (17), areas of different colour (61), lacelike patterns (17), or button-holes (66), pockets (51), and fullness outside a normal body as in a dress (Fig. 6 not shown). <IMAGE>

Title: Software installation in data processing network.
Inventor: HOGGARTH ROGER PHILIP
IPC: G06F9/445
Filed: 1996-03-18
Abstract: A client is arranged so that at power up it makes a request to a server for first boot code which allows the client to boot from its own mass storage. Since the OS is not sent from the server over the network, traffic flow is eased whilst strict control of client software type is maintained. The configuration of a client may be checked prior to software, particularly OS, installation by a server. The server, detecting a new client on the network, down-loads scan code onto the client. The client then runs the scan code and returns hardware configuration data to the server. If the OS of the client is to be modified then the server sends different, second boot code to the client which instructs the client to boot (a new OS) directly from the server. The OS from the server is then installed on the client mass storage device, and subsequent IPLs take place using the first boot code.

Title: Propulsion device using reciprocal motion
Inventor: SHIMSHI EZRA
IPC: F03G3/00
Filed: 1995-02-09
Abstract: Mechanical structures adapted to produce thrust. Said structures include components and mass that rotate about two axes of rotation (20, 10) perpendicular to each other and in two-to-one relationship. In operation, the radius of the rotating mass lengthens and shortens so as to cause unequal forces and unequal pressures to develop at predetermined sections in the cycle of rotation. One structure includes two chambers (21) each having a length and a width and each adapted to permit an inflow (45) and outflow (46) of fluid. The other structure includes a shuttle having two sets of mass members (31), one set of mass members in each chamber. During operation the length of the front chamber aligns vertically, while the length of the back chamber aligns horizontally and the set of mass members within each chamber aligns angularly to said length. The unequal pressures and centrifugal forces (42, 43) cause inflow of fluid into the front chamber and outflow of fluid from the back chamber and the unequal centrifugal forces pull the front mass members apart and the back mass members together which propel the shuttle in a linear movement backward (41). In reaction to the flow of fluid and to said linear movement the frame moves forward (44').
