Title: Container/dispensing apparatus for wafer cones
Inventor: CARROLL GERARD
IPC: A47F1/08
Filed: 1991-02-26
Abstract: A container/dispensing apparatus for wafer cones comprises a container which is subdivided into a plurality of compartments, each of which may contain a stack of wafer cones. Each compartment is provided with a perforated lab (30) which is removable to reveal an orifice through which a wafer cone may be extracted. Each compartment is also provided with at least one flexible retaining finger (32) which is capable of supporting a stack of cones when the perforated tab has been removed and is sufficiently flexible to allow a wafer cone to be extracted from the container without the cone being significantly damaged. The removable perforated tab (30) includes a segment (31) which is removable to reveal a finger access portion, through which a user may insert his finger in order to exert a force on the tab, thereby breaking the perforation and effortlessly removing the tab (30). <IMAGE>

Title: "cellular telephone system"
Inventor: TARGETT DAVID JOHN
IPC: H04W16/32
Filed: 1991-03-22
Abstract: A macrocellular cellular telephone system has cells (macrocells) CI and CII. All the cells CI broadcast a particular Location Area Identity (LAI), and all the cells CII broadcast a different LAI. Upon receipt of an LAI, a macrocellular mobile station (MS) responds and the network thus knows its whereabouts. Communication is thus established with that MS by broadcasting from all cells within the appropriate area I or II. The network is also capable of offering a more restricted service to subscribers to a microcellular system - for example, service in large cities or towns identified at A,B and C. Microcells in these areas transmit LAI's which differ from the LAI's transmitted by the cells available for macrocellular subscribers. By means (for example) of its lower power level, a microcellular subscriber MS can be distinguished from a macrocellular MS and can be denied service unless it is within an area A,B or C. <IMAGE>

Title: Aircraft aircrew life support systems
Inventor: FOOTE JAMES CONWAY
IPC: A62B17/00
Filed: 1991-06-12
Abstract: Inflation pressure of an aircrew G-suit is controlled by an aircraft systems computer 120 sending a pressure demand signal PDEM to a dedicated electronic control unit (ECU) 123 to operate a pressure servo loop 124-129. The computer 120 stores schedules of G-suit inflation pressure against increasing acceleration Gz and decreasing cabin ambient pressure PAMB and outputs the higher to the ECO. The ECU compares an existing G-suit inflation pressure P0 signal with the inflation pressure demand signal and generates a compensated error signal which is combined with the inflation pressure demand signal to provide the servodemand signal. Servo-pressure is regulated by a torque motor controlled valve 124, 125 which receives a servo-demand signal from the ECU 123 and controls movement of inflation gas supply and vent valves 126 and 127, respectively. The use of the ECU for the computationally intensive control task optimises the use of the aircraft systems computer. A combined breathing demand regulator and G-suit inflation pressure control valve which continues to function in the absence of electrical power after bail-out from an aircraft is also disclosed. <IMAGE>

Title: Method of making silicon quantum wires
Inventor: CANHAM LEIGH-TREVOR
IPC: H01L29/06
Filed: 1992-05-01
Abstract: A method of making semiconductor quantum wires employs a semiconductor wafer (14) as starting material. The wafer (14) is weakly doped p type with a shallow heavily doped p layer therein for current flow uniformity purposes. The wafer (14) is anodised in 20 % aqueous hydrofluoric acid to produce a layer (5) microns thick with 70 % porosity and good crystallinity. The layer is subsequently etched in concentrated hydrofluoric acid, which provides a slow etch rate. The etch increases porosity to a level in the region of 80 % or above. At such a level, pores overlap and isolated quantum wires are expected to form with diameters less than or equal to 3 nm. The etched layer exhibits photoluminescence emission at photon energies well above the silicon bandgap (1.1 eV) and extending into the red region (1.6 - 2.0 eV) of the visible spectrum. <IMAGE>

Title: Multiplexed communication with record-format conversion
Inventor: OKAMOTO NAOKI
IPC: H04L69/14
Filed: 1993-12-13
Abstract: A method of multiplex communication control and a multiplex communication controller 6 allow improvement of processing efficiency and effective use of CPU resources when multiple communication lines TL1 - TL3 are connected via the controller to a computer 1 such as a personal computer (PC) or workstation (WS). Data records which are transmitted and received through the communication lines in respective formats are collected by the controller, and are converted to or from a common record format which the computer uses. This reduces load on the CPU and the operating system and loss time due to communication control instructions and stand-by time occurring when multiple communication sessions are simultaneously maintained by a single computer. <IMAGE>
