Patent GB-2136202-A (GB)
Title: Photodiode
Inventor: GUNDNER HANS MARTIN
IPC: H01L31/11
Filed: 1983-03-02
Abstract: Selective detection of light signals of two different wavelength bands is accomplished by two separate pn junctions (13, 14) which are disposed on two different sides of a substrate (1) and are optically in series. The pn junction (13) lying in front in the light path responds to light of, e.g., 850 nm, but not to light in the range from 950 nm to 1,650 nm. The substrate acts as a filter and passes the light of longer wavelength while blocking the 850-nm light, 50 that the second pn junction (14) is only reached by light in the range from 950 nm to 1,650 nm. The device may be used in optical data communication. <IMAGE>

Title: Improvements in metal pouring devices
Inventor: WILKINSON HARRY
IPC: F27D99/00
Filed: 1984-07-24
Abstract: A coreless type induction heating coil (44) surrounds a lower portion (42) of a refractory lined heating chamber (20). The latter is sealingly closed by a cover (46) so that the surface level (52) of the molten metal in a reservoir (36) of a tapping spout (24) can be held constant by applying air pressure to the heating chamber (20). Fresh charge is introduced from time to time into a filling and emptying spout (22) to maintain the surface level of the molten metal in the chamber (20) at all times above the junctures (33,35) of the oblique channels (32,34) with the chamber (20). Because of the absence of a channel inductor, it is practical to empty the pouring device during short shutdown periods with less risk of the refractory lining cracking and cleaning is easier. <IMAGE>

Title: An agricultural machine
Inventor: VAN DER LELY EDWIN
IPC: A01D78/10
Filed: 1985-03-05
Abstract: A hay-making machine comprises a sub-assembly provided with two rake members (2,3). The sub-assembly is connected to a frame (6,9) for pivotal movement about a pivotal axis (11). The axis (1) slopes to the rear from bottom to top. The centre of gravity (22) of the sub-assembly is ahead of the axis (11). Locking means (24,26) is provided for retaining the sub-assembly in a required working or transport position with respect to the frame (6,9). The disposition of the centre of gravity (22) and the axis (11) is such that, when the locking means (24,26) is released, lifting of the machine above the ground causes the sub-assembly to swing automatically about the axis (11) towards a transport position. If the machine is lifted further, the sub-assembly swings automatically towards the working position. <IMAGE>

Title: Adjustment and removal means for plaster casts and orthoses
Inventor: YOUNG DAVID ERNEST
IPC: A61F13/04
Filed: 1985-06-07
Abstract: A device for making orthopaedic casts and orthoses adjustable has a bridge piece supported on upstands at each end, each upstand arising from an optionally splined capture plate. A second bridge piece, identical to the first also having upstands with splined capture plates, is preferably spaced away from the first bridge by narrow membranes extending between corresponding capture plates on each bridge piece. A length of hook tape is doubled around the first bridge and sewn to a length of pile tape to form a strap. The capture plates are firmly bound into a cast during construction, leaving the bridges exposed. A full length narrow strip of the cast is cut away between the bridges, severing the membranes. The strap is now passed around the second bridge, pulled to the tension required to tighten the cast and secured to itself. <IMAGE>

Patent GB-852591-A (GB)
Abstract: 852,591. Gyroscopic apparatus. FRANCAIS ETAT. April 29, 1958 [April 30, 1957], No. 13642/58. Class 97(3) In a gyro-vertical, erection by a circling ball type erector is suppressed by trapping the balls when an applied horizontal acceleration exceeds a pre-determined value, accordingly the effect of the horizontal accelerations of an aircraft which are of sufficiently long duration to displace the gyro-rotor axis considerably from the vertical is obviated since these accelerations also have a sufficiently high value to operate the trapping device. As shown, balls 3 are pushed round stationary circular track 9 by rods 2 carried by rotary plate 1. A horizontal acceleration in a constant direction oscillates pendulums 5 mounted on plate 1 cyclically as the plate revolves and each arm 7 moves downwards when its ball 3 is about to be accelerated away from its rod 2 and upwards when the ball is about to be accelerated towards the rod 2. The downward motion of the rod 7 thus has a braking action on the ball 3 unless the horizontal acceleration is sufficiently great to move the rod 7 below the centre of the ball when the subsequent movement of the latter traps the rod 7 in the lowered position instead of riding it into the upper position and abutting rod 4. The ball 3 is thus held by rod 7 against rod 2 until the revolution of plate 1 reverses the direction of the horizontal acceleration on pendulum 5 and, when the ball is about to be accelerated towards rod 2, rod 7 is freed and rises. In another form (Fig. 5, not shown), the end of rod 7 is provided with a plate which engages ball 3 tangentially. When a number of balls are provided they may be trapped successively as the acceleration increases.
