Patent GB-2004732-A (GB)
Title: Bracelets
IPC: A44C5/20
Filed: 1978-08-09
Abstract: A bracelet securing means intended to secure a pair of end plates 17,18 of the bracelet in face to face abutment, includes a hook 21 and an aperture 19 provided on the respective end plates. The hook 21 is not aligned with the aperture 19 except when the bracelet ends are twisted or sprung apart to a stressed-condition which enables the hook to enter the aperture. When the bracelet is then released, the hook is trapped behind the end plate 17 having the aperture. The arrangement enables a face to face fixing to be obtained even where the end plates are a very small surface area but provides a relatively large bearing area and hence is unlikely to distort and become insecure in use. <IMAGE>

Patent GB-2009973-A (GB)
Title: Control circuit for flat-irons
IPC: D06F75/26
Filed: 1978-11-10
Abstract: In an electrical control circuit for a flat-iron a sensing resistor 7 has a resistance which depends upon the temperature of the heating element 2 and the voltage drop across the resistor 7 is compared with a reference voltage adjustable for different required temperatures, to control the supply of current to the element 2. A current sensor 22 monitors current flow through resistor 7 and blocks the supply of current to the element 2 should the current flow be below a pre-set limit. The circuit may alternatively be arranged to block the supply of current to the element 2 if the sensing resistor current is above a pre-set limit or outside pre-set upper and lower limits. The means for detecting whether the monitored current is outside the specified limit(s) is a differential amplifier comprising two Darlington-connected pairs of transisors. <IMAGE>
Patent GB-2008219-A (GB)
Title: Pipe Connection
IPC: F16L21/00
Filed: 1978-11-16
Abstract: In the pipe connection a sealing sleeve (3) is pushed over the pipe ends (1, 2) which are to be joined together and which abut axially. The outer surface of the sealing sleeve (3) widens conically from its ends towards the longitudinal centre. Over the conical outer surface parts are placed clamping means (4, 5, 6) enabling the sealing sleeve to be pressed radially against the pipe ends. In order to prevent the pipe connection from leaking after a short time through the flowing of the plastics material of the sleeve it is proposed that a crystalline proportion of more than 24% should be present in the plastics material. If the joint is to be bridged electrically. contact clips (7) can be pushed onto the ends of the plastics sleeve to provide contact between the pipe ends and clamping means. A corrosion-resistant sealing ring (8) may be trapped between the pipe ends within the sleeve. <IMAGE>
Patent GB-2267555-A (GB)
Title: A magnetic proximity fuse for use against ferrous targets
Inventor: THOMAS WILLIAM PAUL
IPC: F42C9/14
Filed: 1978-12-19
Abstract: A magnetic proximity fuze for a missile warhead switches to a mine mode if the missile fails to pass within detonating distance of a ferrous target. A voltage is developed in a coil 5 to detonate the warhead in the vicinity of the target but, in the event of a miss, a voltage of opposite polarity is generated in the coil by movement of a magnetic core 4 upon impact of the missile with the ground to thereby effect switching to the mine mode. The core is moved by inertia or by a button 6. <IMAGE>

Patent GB-2042717-A (GB)
Title: Method and Apparatus for Examining Objects
IPC: A01D33/04
Filed: 1980-01-18
Abstract: Potatoes carried on a roller table conveyor 12 are presented in transverse rows at an inspection area illuminated by lamp 15 from a first direction and observed by a line imaging camera 18 along a second direction arranged by a mirror 17 to be approximately at right angles to the first direction. The camera 18 scans repeatedly across each row and provides an output detection signal representing the reflected radiation. The camera 18 observes a sharply illuminated boundary of the potatoes against a dark background and a signal processing unit 20, e.g. a micro computer, processes the detection signal to provide an information signal representative of a dimensional parameter of a potato, for example the length of a potato along the direction of its row. Size grading, for example, may be effected by directing potatoes along different routes by deflecting fingers 22 controlled in dependence upon the information signal. In a further embodiment, Fig. 4, the potatoes are illuminated and viewed from two different directions and at spaced apart locations to provide a measurement of the potatoe's width or girth. The apparatus for examining objects may be combined with sorting apparatus disclosed in co-pending Patent Application No. 7938336 to allow an operator to indicate a potato to be rejected by subsequent deflecting means. The deflecting means may be actuated in dependence upon an identifying signal identifying the reject potato and an information signal representative of a dimensional parameter of the potato to allow appropriate actuation of the right number of deflecting fingers, corresponding to dimension of the object being rejected. <IMAGE>
