Title: Reinforcement particles pre-coated with metal matrix; particle-reinforced metal matrix composites
Inventor: WARD-CLOSE CHARLES MALCOLM
IPC: C23C14/50
Filed: 1993-10-14
Abstract: Ceramic reinforcement particles are coated with sufficient matrix material such that, on hot consolidation, the deposited material superplastically deforms and diffusion bonds to produce a fully-dense metal matrix composite without the addition of further matrix material. The ceramic powder may be coated using any known physical vapour deposition technique, on condition that a suitable arrangement is provided to ensure that the particles become evenly coated. During the coating process the powder is contained in a tray exposed to the deposition flux, even coating being achieved by motion of the tray (eg by tilting as illustrated in Fig 1) or by stirring of the particles. The tray may also be subjected to periodic shock or impulse loading. In another embodiment the tray may be rotated, a stationary comb being mounted above the tray with its teeth in contact with the charge. Upon rotation the charge is stirred by the teeth of the comb to expose fresh surfaces of the ceramic particles to the coating flux. More than one physical vapour deposition step may be employed. The ceramic particles may be formed of silicon carbide and the metal matrix material may be Ti-6Al- 4V alloy. <IMAGE>

Patent GB-2302281-A (GB)
Title: Control for psoriasis
Inventor: PHILLIPS ROBERT IRVINE
IPC: A61K9/00
Filed: 1995-06-20
Abstract: A medicated shampoo effective against Psoriasis is used on Psoriasis on the parts of the body, other than the scalp. The shampoo is applied to wetted skin, lathered up and left to dry. Use of the shampoo will, in effect, gently but painlessly, burn the skin and the red Psoriasis spots will be burnt out, leaving the affected area a pinkish colour; one then ceases using the shampoo and allows the area to dry and the skin to flake off as new skin grows; no creams, lotions or oils of any kind should be used to assist the dry areas. The method is painless and harmless and takes no more layers of skin off than using a facial scrub.

Patent GB-2312104-A (GB)
Title: Deceleration warning system for a road vehicle
Inventor: WATSON STEPHEN GEORGE
IPC: B60Q1/44
Filed: 1996-04-10
Abstract: An externally perceivable signal on a road vehicle is actuated in response to a high rate of deceleration of the vehicle. Deceleration above a threshold level may close an inertia switch 10 thereby energising a set coil 32 of a bistable relay 30 so that contacts 34 of the relay 30 close to energise a further relay 38 whereby the hazard warning lights 13 are activated through a switch 42 of relay 38. The hazard lights 13 remain energised until the normal brake light switch S opens. Opening of the brake light switch S is sensed by a differentiating circuit 46,48 and a diode 50 resulting in an amplification and de-bounce circuit 51 momentarily energising a relay 40 causing momentary energisation of a reset coil 36 of bistable relay 30, such that contacts 34 and 42 open in turn to deenergise the hazard lights 13. The inertia switch 10 may have a mass (20, Fig.2) slidable against the bias of an adjustable spring (26), or an inertial mass (78, Fig.4) adjustably attached to the operating lever (76) of a microswitch (72). In alternatives, one or more indicator lights may be activated instead of the hazard lights 13, the reset coil 36 may be energised by a manually operated switch, and deceleration may be sensed by means responsive to brake fluid pressure or may be calculated electronically from the vehicle speed indicated by the speedometer or by a sensor on a vehicle wheel.

The guide plate portions 4 include chamfers 7 that release the plates from the guiding portion 6 when the male screws 2 have been screwed down sufficiently to reach the respective terminal strips 11. This allows the washers 3 to pivot and thus accommodate differently sized contacts. The covers 10 can be formed integrally with an arc quenching cover for the electromagnetic device.
Patent GB-2316696-A (GB)
Title: Release mechanism
Inventor: DYBEVIK ARTHUR HRRMAN
IPC: E21B23/04
Filed: 1996-08-27
Abstract: A tool I can be released from a tool string in a wellbore by setting the tool and applying reverse torque to the tool string for an extended period. The release mechanism (200) comprises a latch (250) including a plurality of collets (253) which are held in a radially extended position to secure the tool to the tool string. A first member (201) is connected to the tool string and to the latch (250). A second member (202) is connected to the latch. After the tool is set reverse torque is applied to the first member (201) to rotate it relative to the second member (202) which is constrained against rotation by the action of the tool on the latch. When the first member (201) has rotated sufficiently the first and second members occupy a release position in which downward movement of the first member (201) relative to the second member (202) (which was previously blocked) is permitted. This movement releases the latch (250) and hence allows separation of the tool and the tool string. In order to prevent accidental release relative movement between the first member (201) and second member (202) is inhibited by providing both members with vanes (204, 208) and filling the chamber therebetween with hydraulic fluid. The damping is preferably arranged so that a significant reverse torque, for example 3500ft/lbs must be applied for a prolonged period, for example 30 seconds, before the latch can be released. The mechanism may form a primary or a secondary release arrangement.

Patent GB-2312094-A (GB)
Title: Stacked capacitor type DRAM
Inventor: ARATA SHINOBU
IPC: H01L21/768
Filed: 1997-04-09
Abstract: In a stacked capacitor type DRAM having an intermediate conductive pad 5 which is contacted at one end with one source/drain region 11 and at the other end with a capacitor lower plate 9 of the stacked capacitor, the intermediate conductive pad is patterned at the same time as bit lines (20, fig 4) are patterned, so that the number of manufacturing steps can be reduced, and the manufacturing period can be shortened. Furthermore, the intermediate conductive pad 5 is patterned to cover a word line 3a, so that the intermediate conductive pad acts as an etching stopper when an anisotropic etching is conducted to form a contact hole 8 for interconnecting the intermediate conductive pad 5 and the capacitor lower plate 9. Therefore, even if misalignment occurs in the patterning, it is possible to prevent a short-circuiting between the capacitor lower plate and the word line.
