Title: Joint prosthesis having insulated stem
Inventor: BIMMAN LEV
IPC: A61L27/50
Filed: 1995-04-03
Abstract: The prosthesis has head and stem portions 102, 104 and means such as a screw 106 connecting them, the stem comprising a core 110 of strong, resilient material such as spring steel, having flexure characteristics similar to those of bone, and a cover 112 of body-compatible material which insulates the core from surrounding body fluids and tissue. The cover may also insulate the stem core from the head portion to prevent any electrochemical reaction therebetween. Biocompatible material 126 may insulate the screw head from body fluids etc. and an insert 124 may insulate this head from the head portion 102. Anti-rotation means may be provided to prevent relative rotation of the head and stem portions. In an alternative embodiment, the head portion carries a threaded pin for receipt in a hole of the stem. The modular, two-part structure of the prosthesis allows stem and head portions to be selected for best fit. <IMAGE>

Patent GB-2305288-A (GB)
Title: Speech recognition system
Inventor: INTERNATIONAL BUSINESS MACHINE
IPC: G10L15/06
Filed: 1995-09-15
Abstract: A speech recognition system for discrete words uses a Hidden Markov Model (HMM), which is nominally adapted to recognise N different isolated words, but which is trained to recognise M different words, where M>N. This is achieved by providing M sets of audio recordings, each set comprising multiple recordings of a respective one of said M words being spoken. Only N different labels are assigned to the M sets of audio recordings, so that at least one of the N labels has two or more sets of audio recordings assigned thereto. These two or more sets of audio recordings correspond to phonetically dissimilar words. The HMM is then trained by inputting each set of audio recordings and its assigned label. The HMM can effectively compensate for the phonetic variations between the different words assigned the same label, thereby avoiding the need to utilise a larger model (ie to use M labels).

Title: A gate for gating a pig in pipework
Inventor: SEALE DONALD JOHN
IPC: F16L55/46
Filed: 1996-09-24
Abstract: The gate comprises an annular member (26) which, like a ordinary butterfly valve, can be pivoted selectively either to a end-on position, in which it blocks passage of a pig (14) but allows fluid product to flow, or a broadside position, in which both pig (14) and fluid product can pass through the annular member (26), which is always bathed in and washed by the fluid product. The pig (14), when held by the gate (26) is retained by longitudinal rods (18) or narrow flat bars forming a cage, to allow the pig to be washed by the fluid product. Upon gate opening, the pig is either propelled by the fluid, e.g ice cream or cosmetic, or by a liquid (e.g potable water) propellant from a branch, controlled by a valve.

Title: Home security system for detecting an intrusion into a monitored area using an infrared detector
Inventor: DOCKERY DEVAN
IPC: G08B13/19
Filed: 1996-09-25
Abstract: A security system having a free-standing intrusion detector 12 with a radio transmitter 24 coupled with a portable receiver (50, Figure 2) to alert a homeowner that an intrusion has taken place or occurred within a pre-set time period. An area is monitored by an infrared detector that activates the transmitter upon the receipt of abrupt differences in infrared radiation levels, associated with an intrusion. A radio signal is emitted by the transmitter and is modulated 22 for a preselected period of time. The receiver responds to this signal and generates a first signal that is displayed for this preselected period of time, indicating that an intrusion has been detected within this time period and that the probability of the intruder still being present, is great. After the preselected period of time has elapsed, a second signal is generated by the receiver indicating that the time since the intrusion took place is greater than the preselected time period. Once the intrusion detector is activated, the signal is continuously transmitted to the portable receiver until the intrusion detector has been reset.

Title: Manufacture of earth boring drill bits
Inventor: SOUTHLAND STEPHEN G
IPC: B29C67/00
Filed: 1997-07-22
Abstract: A mold 24 is formed for an earth boring bit 26 by designing the bit geometry in three dimensions using a computer aided design (CAD) system and then feeding the geometry data of the design to a layering device. The layering device then builds the mold a layer 20 at a time. Materials used in building the mold include, sand, graphite, ceramic, clay, other refractory materials, plastic, rubber and wax. Once the mold is formed, powdered steel or tungsten carbide is poured into the mold and is cured by press molding or infiltrating with a binder forming a bit body. Cutting elements are then inserted in the bit body forming the earth boring bit. In alternative methods described (i) a wax model of a bit body is formed by CAD layering, a mould is formed from that model and a bit body finally formed in the mould, (ii) formers are formed by CAD layering and interconnected to form a secondary mould from which a primary mould is formed, a bit body being formed in that primary mould and (iii) a master mould is formed by CAD layering, a master bit body formed in that mould, a secondary mould formed from the master bit body and a desired bit body formed in that secondary mould.

Title: Detecting sensor misalignment
Inventor: WINNER HERMANN
IPC: G01S7/292
Filed: 1997-12-04
Abstract: A vehicle 10 is quipped with a gap sensor 11, such as a radar, lidar or infra-red sensor. In order to determine if the gap sensor is misaligned or otherwise misplaced, the vehicle is equipped with a device 13 which measures the inclination of the vehicle, for instance by measuring the extension of the vehicle's springs. Control unit 12 produces a histogram (fig 2a) of the vehicle's inclination over time and a histogram of the output of the gap sensor over time (fig 2b); this latter histogram will have a missing section (24 or 25) if the sensor is misaligned or misplaced; the missing section is located by correlating the two histograms.

Title: Controlling roughness in lean-burn engines
Inventor: MEYER GARTH M
IPC: F02D41/18
Filed: 1997-12-09
Abstract: Roughness is calculated by measuring, at 60, the time interval PIP between an event, Top Dead Centre of one cylinder, and the corresponding event on the next firing cylinder. Differences in PIP values, DPIP, between adjacent cylinders in pairs are calculated, at 62, and normalized, 64. Normalized DPIP in the cylinder pairs are averaged over time, 66, and the instantaneous values compared to the averages, 68. Resulting differences DDPIP are squared, 70, weighted, 72, and the square root ALRGH is taken as the level of actual roughness, 74. This is then compared with a desired level (DLRGH, Fig. 3) derived from engine speed and cylinder air mass detected by an air flow sensor. The resulting error, after suitable gain-processing, is used to correct the air/fuel ratio to bring the engine to the desired level.
