Title: IC engine ion current detection circuit - uses selective masking to eliminate noise pulse component in circuit output signal
Inventor: OHSAWA TOSHIO
IPC: G01R19/00
Filed: 1992-10-02
Abstract: The ion current detection circuit monitors ion current produced during combustion of a gas mixture supplied to an internal combustion engine. Marking of the signal is provided by the circuit during the time intervals in which noise pulses are produced by application of the HV to the ignition coil (1). Pref. the masking interval for the circuit output signal is synchronised with the ignition pulses, in connection with excitation and decay of the ignition coil. The presence or absence of registered pulses is used to determine precisely whether the mixture is combusted or not. ADVANTAGE - Simple elimination of noise pulses.

Title: Long fibre-reinforced product prodn. - involves laying down resin impregnated fibre along axial path between rotating end plates with hooks and after curing resin, using as mandrel for final prod.
Inventor: WAREK MICHAEL
IPC: B29C53/80
Filed: 1992-11-12
Abstract: A filament placing process for prodn. of long fibre-reinforced plastic products involves laying down a continuous fibre (12), pref. impregnated with a crosslinkable resin, between two rotating end plates (22,24) with fibre holding devices (26,28). Fibre is placed by a carriage (46) moving backwards and forwards between the end plates (22,24) to build up a tubular structure comprising axially aligned and if necessary circumferential fibres. On completion of fibre lay down the resin is cured to form a tube which serves as a mandrel for further fibre lay down. Process plant comprises a lathe-type arrangement with head stock supports (32,34) each carrying a rotating plate (22,24) with fibre take-up hooks (26,28) on the rear face, the hooks (26,28) being arranged at the circumference of the product under prodn. A carriage (42) with a fibre feed (46) moves backwards and forwards along a rail (44) to place the fibres (12) over the hooks (26,28) at both ends. The end plates (22,24) can be exchanged and are shaped to suit the profile of the final product. Fibres (12) run over the plate (22,24) edges during lay-down. USE/ADVANTAGE - Used to produce a long fibre-reinforced product, e.g. poles. Eliminates the use of a solid mandrel allowing prodn. of shapes not possible with such mandrels and also accelerates the process.

Title: Adaptor for busbars
Inventor: GOETZ HANS-JOERG
IPC: H01R25/14
Filed: 1993-04-19
Abstract: An adaptor for fitting to a busbar having a plurality of electrical conductors, which are arranged in a plane alongside one another in an insulated manner, has contact elements for application to the electrical conductors, which are blade contacts constructed in a spherical shape on their contact surface. These blade contacts are located at the ends of spring arms of bending springs.

Title: Spectacle hinge
Inventor: HUELLER DIPL-AUTOMOBIL-DESIGNE
IPC: E05D5/12
Filed: 1993-07-03
Abstract: The spectacle hinge which is applied for relates to all types of spectacle frames. The novel hinge has a typical construction in that it has no gaps, screws and pinching points (compression points, crimped points). In the event of a mechanical overload, the hinge, rather than being damaged, comes apart and, as a result of its clip-in mechanism, can be returned to its original functional state by any individual. The basic novel feature of this spectacle hinge results from the commercial suitability and the vast range of design possibilities, derived from the function, which influences the overall aesthetic concept of the spectacles.

Title: Pulse width modulator with temporary memory - has pulse width data input bus, with data inversion and clock pulse signal counter
Inventor: HAN DAE KEUN
IPC: H03K7/00
Filed: 1993-09-03
Abstract: The memory (10) temporarily stores pulse width data fed via a bus and inverted, the data determining the pulse width. The counter (20) handles a clock pulse signal (CK) in response to an external pulse width modulation release signal (RE). A comparator (30) deals with a number of logic 0-bits of the inverted pulse width data of the memory and logic 1-bits of the counter data. It transmits a high level signal, when the number of the logic 0-bits is higher, or equal w.r.t. the logic 1-bits. It transmits a low level signal in a reverse instance. An output device (40) blocks the comparator output signal and transmits a pulse width modulation signal (PWMO). USE/ADVANTAGE - For modulating input signals into desired pulse signals, with simple design, high processing speed and easy integration in single chip.

Title: Removal of hard coatings by ultra high pressure jets - involves nozzle set at certain distance from surface and producing flat pressurised jet
Inventor: RAGHAVAN CHIDAMBARAM
IPC: B26F3/00
Filed: 1993-12-08
Abstract: The nozzle (12) has an inlet opening at one end and an outlet opening at the other end. It is positioned so that the distance between the outlet opening and surface being cleaned is between 1.27 and 2.54 cm. A volume of pressurised fluid is then forced through the nozzle so that the fluid leaves the outlet as a high pressure flat jet which is guided over the surface at a rate of between 10.16 and 40.64 m/min. The nozzle can have an outer surface and inner surface. The inner surface is defined by a conical bore extending through the nozzle from the inlet to the outlet end. A wedge like slit or notch extends from the outlet end to the inlet end so that the shape of the outlet opening is defined by the conical bore crossing the slit which causes the emerging pressurised fluid to leave with a linear contact force. USE/ADVANTAGE - High-pressure fluid jet for cleaning aircraft components gives effective uniform cleaning action.
