IPC: G01S7/41
Filed: 1985-12-20
Abstract: A radar target identification system which operates analogously to a hologram comprises a radar transmitter (1) spaced apart by some distance from a receiver (5), the transmitter having a transmission antenna arrangement for transmitting microwave energy directly to an aerial array of the receiver (5) and to a target (3) so that the aerial array (5) of the receiver receives microwave energy reflected from the target (3) and directly radiated microwave energy, the aerial array (5) which feeds the receiver comprising a planar array of individual aerial elements (7), each individual element (7) being connected to a fast Fourier transform unit (9) whereby an interference pattern present at the aerial is processed for providing an electronic representation of the target (3) shape. The electronic representation may be displayed on a VDU (11) or compared with previously stored information in a comparator (12). <IMAGE>
Patent GB-2175353-A (GB)
Title: Plain bearings
Inventor: IPPOLITO RODOLFO MORENO
IPC: F16C33/26
Filed: 1986-05-14
Abstract: A plain bearing (10) is formed by helically winding a wire to form a bearing surface (10B) for supporting a rotating member (20). During the winding operation the bearing surface of the wire becomes convex. This convexity, in conjunction with the helical winding, provide some degree of hydrodynamic lubricating force even in slowly rotating, highly loaded bearings such as rotary drill bits. The convex bearing surface also accepts misalignment of the bearing surfaces with generally evenly distributed loading among all coil segments. <IMAGE>

Patent GB-2216593-A (GB)
Title: Connectors for use with strapping
Inventor: CLARK DAVID FRANCIS
IPC: A44B11/00
Filed: 1989-05-25
Abstract: The connector comprises a first and second component (1) and (2) each made as unitory plastic moulding: the first component (1) comprises a plate formed with a longitudinal central slot, while the second moulding is shaped like the letter D, having a bar (4) and an attachment portion (5) the bar being unable to pass through the slot. A bight (7) of the strapping extends through the slot and around the bar. The strapping and connector may constitute part of personal harness. Reins may be attached to portion (5). When the strapping is tensioned the position of the connector cannot be adjusted, but when it is slack the position of the connector can be adjusted along the strapping. The bar (4) is of circular cross-section to enable it to rotate. In a preferred construction resilient jaws (3) on the plate releasably secure the bar in place, the bar being snapped between the jaws which are formed with grooves facing each other. The bar (4) may have a central gap so that bight can be introduced into the component (2) by manipulating the bight through the gap. <IMAGE>

Title: Retractable parking and docking mirrors
Inventor: REEVES BRIAN CHARLES
IPC: B60R1/00
Filed: 1989-08-10
Abstract: Extendable and retractable, universally adjustable, friction set mirrors (1, 2) are used in their elevated states to provide rearward and forward vision of areas normally hidden by bodywork of vehicles or hulls of boats and aircraft during parking and docking. The extension systems (3 and 4) are elevated by telescopic or other suitable means and driven by electricity, mechanical force or hydraulics. They retract the mirrors into relatively dirt proof receptacles mounted in or on the vehicle bumpers or bodywork and in the case of boats and aircraft, in or on the hulls or deck housings, after use, to prevent damage and restore visibility. The system enables parking or docking to take place without assistance or guesswork, protects the mirrors, guarding against damage to themselves or other parties and keeps them clean for subsequent use. <IMAGE>

Title: Voice activated access control system
Inventor: CASSIDY GERALD ANTHONY
IPC: G07C9/00
Filed: 1989-11-15
Abstract: An access control system includes a pair of lockable doors 12, 14 and input means (a key pad) 24 for initiating a voice recognition procedure. The system includes a microphone 20, memory means for storing a voice-print of a predetermined password and processor means for analysing the microphone output and for comparing the microphone output with the stored voice-print.

The embodiment of Figure 1 has solenoid controlled latches 16 and a microswitch 18 for each door 12, 14. The user may open outer door 12 to enter booth 10 and operates key pad 24 with a unique four digit code; a loudspeaker 22 then prompts user to speak password - this is compared with voice-point and the direction which person should have come into booth 10 is also checked. In a 'high security' mode a number of passwords are spoken and checked. Figures 2-6 show flow charts. <IMAGE>

Patent GB-2231632-A (GB)
Title: Pressure balanced hydraulic coupling
Inventor: SMITH III ROBERT E
IPC: F16L37/35
Filed: 1990-06-18
Abstract: A pressure-balanced hydraulic coupling, for use in undersea drilling and production operations, has radial passageways (34, 85) communicating between the male (10) and female (20) members such that substantial fluid pressure is not exerted against the face (45) of either member during coupling or uncoupling or during the coupled state. Check valves (33, 82) in both the male and female members are opened when the male member probe (44) is fully inserted into the receiving chamber (107) of the female member. Mutually opposed valve stems (65, 106) extending from each check valve contact one another to effect the simultaneous opening of each check valve, and allow fluid to flow through a valve port and then radially through matching fluid passageways (38, 85) of the male and female members match up at their longitudinal surfaces so that fluid pressure between the male and female members is in a substantially radial direction and is not exerted at the end face of either member. <IMAGE>

Title: Drilling unit of assembly robot
Inventor: SUZUKI TAKASHI
IPC: B23Q9/00

Abstract: The unit is mounted on an arm of the robot. To enable a drill bush 21 of a nose piece 20, for guiding a drill 12, to be adjustably moved into exactly registering relation with a bore of a template 22 laid on a workpiece 13, the nose piece 20 is mounted on a first cylindrical member 18 which is mounted on a second cylindrical member 25 through a first compliance mechanism comprising elastic support members 29 which constitute oblique links of a trapezoidal link mechanism having an imaginary intersection of the oblique links at a front end of the drill bush 20. The drill bush 20 can therefore make a swinging motion about the intersection. The second cylindrical member 25 is mounted on a guide plate 34 through contact by a laterally slidable flange 26 forming a second compliance mechanism which enables the second cylindrical member and hence the drill bush to adjustably move in a radial direction of a rotational shaft 10 of the drilling unit. Each compliance mechanism can be locked against use by respective actuated pin units 31, 37. After adjustment of the nose bush 20 in the template bore, angular rotation of the nosepiece 20 occurs to bayonet lock with bolts 24. <IMAGE>
