Patent GB-2199713-A (GB)
Title: Optical communication system
Inventor: GODDARD ISOBEL JENNIFER
IPC: H04B10/25
Filed: 1986-12-31
Abstract: A difficulty in optical systems, especially where polarisation-dependent (PD) elements are used, is that the light to be dealt with is subject to fading. To minimise this, the input beam, e.g. from an optical fibre, is applied to a polarisation beam splitter (1), which resolves it into two orthogonally-related beams (2, 3). These are applied to PD elements (4, 5) and therefrom to two detectors (6, 7), or to one detector (6). In an alternative arrangement, only one PD element is used. Such an arrangement, in its "all fibre" version is usable at the input of a node of an optical fibre LAN. <IMAGE>

Patent GB-885109-A (GB)
Abstract: 885,109. Detonator control system and apparatus. SOC. D'ELECTRICITE MORS. Dec. 21, 1959 [Dec. 19, 1958], No. 43320/59. Class 105. In a system for positioning detonators on a rail track when a train passes a danger signal each positioning device comprises, mounted adjacent the track, a frame 3, Fig. 1, supporting a tube 4 within which is housed an interchangeable cartridge 5 containing a detonator 6 carried by a rod 7 attached to a piston 8 which is retained in a retracted position, against the action of a spring 9, by a bar 12 which can be shattered by an explosive charge 13 ignited by current in the wire 14. A group of five such devices are controlled by the circuit shown in Fig. 5 in which, when a vehicle passes a signal at danger, relays CC and V<SP>1</SP> are released and a pedal Pd is operated. As a result, relay CA releases and at its back contact a applies a positive voltage to five parallel circuits each comprising in series a high resistance winding a and low resistance winding m of a relay (A1-A5) and a charge ignition wire (F1-F5). The first relay to operate, e.g. A3, operates relay AUX via front contact A3d whereby the positive supply to the relays is broken at contact AUXa. Relay A3 is maintained energized via b.c. c of relay A1, b.c. c of relay A2, f.c. b of relay A3, the low resistance winding m of relay A3 and the ignition wire F3. The initial current through the circuit, including the high resistance winding of the relay, increases as this winding is switched out of the circuit to a value sufficient to heat the wire F3 (14 in Fig. 1) to a temperature which ignites charge 13 and the detonator is pushed forward by spring 10 to position 61 where it is detonated by the train wheel. Figs. 2-4 (not shown) indicate alternative arrangements using a fusible link or magnetic circuit for retaining the piston against the action of the spring.

Patent GB-906659-A (GB)
Abstract: 906,659. Voltage measurement SCHLUMBERGER WELL SURVEYING CORPORATION. July 29, 1960 [Aug. 3, 1959], No. 26516/60. Class 37. [Also in Group XL (c)] Acoustic well-bore logging apparatus is characterized by an electric circuit responsive to a selected half-cycle of the received signal to supply to a recorder a signal corresponding to the peak amplitude thereof. The output of magnetostrictive receiving transducer R2 is fed to a pulse generator 31 having a bias control circuit (not shown) coupled to a surface sensitivity control 17 adjusted above the peak level of the first half-circle of the amplified receiver output but below the expected peak level of the second half-cycle; errors due to low amplitude noise are thus avoided. Generator 31 is controlled also by a gate circuit (not shown) which applies a pulse to the generator immediately prior to the earliest possible arrival of a transmitted sound pulse at transducer R2. Peak voltage measuring circuit 40 remains inoperative until generator 31 produces a pulse to trigger multivibrator 42. Measuring circuit 40 comprises a normally-conducting triode 55 such that cathode follower 51 output is insufficient to cause diode 56 to conduct; the multivibrator produces a pulse to cut-off triode 55 for the second half cycle of the received wave. The time constants circuits 57, 58 and 61, 63 are made sufficiently long to ensure that the peak voltage is recorded. Transistor pulse circuits, Fig. 3. In an alternative peak voltage measuring circuit monostable multivibrator 81 is triggered by generator 31 to gate the receiver output via amplifier 68 in series gating circuit 77, 80 the output from which is applied to cathode follower 91 via current-amplifying transistor 83a which charges capacitor 86 via diode 85.

Title: Contaminant-proof collapsible container
Inventor: TSAO YE-MING
IPC: B65D21/02
Filed: 1991-12-06
Abstract: A contaminant-proof collapsible container (10) comprises a body (11) on which a neck (20) is mounted and a non-return valve that allows liquid to flow out easily but restricts the ingress of liquid or air located in the container neck, said valve having a plurality of elastic webs (14) around it to press a convex portion (13) against the outlet, and consequently prevent external air or liquids from flowing into the body unless specific tools are used. An indentation (16) is provided in the bottom of the container large enough to hold the neck of another like container. When pouring liquid out of the container, liquid flows out past the convex portion (13) and the decrease in volume is followed by contraction of the container facilitating visual inspection of the amount of residual liquid. Such contracted containers can be joined end to end to facilitate recycling and to minimise the volume for recycling. <IMAGE>
