Title: Battery economy apparatus
IPC: H04B1/16
Filed: 1969-11-27
Abstract: 1325880 Radio signalling PYE Ltd 20 Nov 1970 [27 Nov 1969] 58147/69 Heading H4L In a radio receiver including a calling arrangement in which the battery supply is interrupted periodically during idle periods to conserve battery power and is made continuous on the reception of a predetermined sequence of calling tones, the economizer circuit E, Fig. 2, is of the type disclosed in Specification 1,185,909, which includes an electronic switch and stabilizer ESS driven by a multivibrator MV and a clamp L which can hold the switch closed by means of a control signal applied to a delay unit D. The unit D provides a delay in reversion to periodic switching on cessation of the control signal to allow for temporary drop-out of the signal. The received signals are demodulated at R and supplied via de-emphasis and volume control stage DVC, gate G1, which is blocked via circuit HPF, S, in the presence of noise, and amplifiers AD, AOP to the loud-speaker LS, the amplifier AD being cut off by gate G4 prior to the receipt of the calling tones A and B. The output of R is also supplied via amplifier and limiter TPA, filter AN for tone A and amplifier AA to a detector ATD and via filter BN for tone B and amplifier BA to a detector BTD. In the absence of correct tones the multivibrator MV is running and the switch ESS provides interrupted D.C. to the major parts of the receiver. During conduction periods of switch ESS the presence of a carrier of correct frequency reduces the noise output on line 17 and opens gate G1. The output of each detector ATD, BTD is 0 and under these conditions an output of 0 is supplied to gate O from a bi-stable BM together with the output 0 from detector ATD resulting in gate G2 conducting to short the input of delay D. Gate G4 also conducts due to the 1 output of bi-stable BM to mute the amplifier AD, and gate G3 conducts due to the inverter I to short circuit the input of the filter BN. When the tone A is received the output from detector ATD via gate O blocks gate G2 so that the capacitor of delay D is charged via line 17 and R2 to operate the lock L to hold switch ESS conducting. The charge on the capacitor via inverter I blocks gate G3 so that filter BN is operative and when tone A ceases the input is removed from delay D which holds gate G3 open for the delay period. In Fig. 3 (not shown) the output from D via inverter I is dispensed with and gate G3 is controlled by the output of detector ATD via an additional delay circuit (DG). In either circuit when the tone B is received the output of detector BTD changes over bi-stable BM to block gate G4 to allow signals to reach the loudspeaker and gate G2 becomes conductive. This condition is retained by the bi-stable BM until a switch DS in the supply line is operated causing the economizer to revert to periodic switching after delay D.

Title: Optical fibre manufacture
IPC: C03B37/023
Filed: 1972-01-04
Abstract: 1328612 Drawing glass fibres STANDARD TELEPHONES & CABLES Ltd 4 Jan 1972 227/72 Heading C1M An optical fibre 10 is produced by forming a glass rod 8 having a core region 7 of higher refractive index by causing molten glass 1 in a crucible 2 to flow under gravity over the rim of a tube 5 and out through its bore, the tube 5 extending vertically through the base of the crucible, the surface of the glass 1 in the crucible being in contact with a substance, such as a tube 4 of a modifying oxide, which reacts with the glass 1 to provide, at least in the region surrounding the rim of the tube 5, a surface layer 6 of higher refractive index than that of the underlying regions of glass 1, which surface layer 6 is entrained down the centre of the tube 5 to form the core 7 of the rod 8 which rod is drawn down to form the fibre 10. The substance may be a vapour, liquid or solid giving either a straight diffusion or an ion exchange. As shown, for a sodium calcium silicate glass 1, the tube 4 is of barium oxide. The crucible 2 is heated by a coil 3 and the level of glass 1 is maintained by the addition of a ring of powdered glass 11 outside the tube 4. Heaters 9 allow the final drawing of the fibre 10 from the rod 8.

Title: Mobile apparatus for producing a levelled or inclined surface on the ground over which it moves
IPC: E01C19/00
Filed: 1971-07-14
Abstract: 1338572 Automatic attitude control ROBERT McGREGOR & SONS Ltd 14 July 1971 [7 Aug 1970] 38235/70 Heading G3R In a road making machine, e.g. a concrete paving machine, a known type course sensor on the machine cooperates with means defining a datum level (e.g. a single guide wire) to control the height relative to the datum level, of one end of a road surface forming member extending transversely to the direction of movement of the machine, while a spirit level sensor arrangement controls the transverse slope angle of the said member. The spirit level 16 (Fig. 5) has three electrodes immersed in electrically conductive fluid, movement of the bubble causing it to function as a variable potentiometer when connected in an A. C. bridge 17. The bridge, is balanced when the level sensor is horizontal. Any unbalance is amplified and rectified at 18 and applied to a relay 19 which selectively operates one of a pair of normally closed pilot relays 20 depending upon whether the bridge output is high or low. Relays 20 in turn operate a respective relay 21 having a time delay facility, to cause operation of an electro-hydraulic valve 22 controlling a hydraulic ram 14. The ram accordingly tilts the machine until the bridge is rebalanced. To accommodate cross fall angles from 1 in 14 to level the spirit level is mounted on a pivoted beam or sine bar 25 Fig. 6 which is biased by springs against a spindle of a micrometer 28. With a distance of 10" between fulcrum 26 and the spindle a direct sine reading can be obtained using a 2" micrometer. The micrometer spindle is driven by a servomotor 30 via a gearbox 31. Thus to surface a length of road from level to say a crossfall of 1 in 25 at a constant rate of change, a programme can be set up whereby the servomotor speed and direction is controlled in relation to the machine advance rate and the desired change in crossfall, the spirit level acting to adjust the machine to follow the programme. The hydraulic system is damped to prevent over-run and hunting also the time lag on relays 21 prevents 'flapping' of the valve 22. Alternatively pneumatic rams or mechanical actuators may be used.

Abstract: 1343981 Protective arrangements DEFENCE SECRETARY OF STATE FOR 17 May 1972 [21 May 1971] 16182/71 Heading H2K An arrangement for controlling the supply to a load 2, includes a current sensor 4, a pulse shaping circuit 6 which provides a single pulse of predetermined shape, magnitude and duration when the current sensor output exceeds a predetermined magnitude, and a comparator circuit 7 which provides a control signal whenever the current sensor output is greater than the instantaneous voltage of the pulse. The control signal may cause the opening of a "contactor" formed by an electromagnetic relay or a thyristor switching circuit. The current sensor may be a magnetic amplifier if the power supply is from a D.C. source, or one or more current transformers if the supply is a single phase or multiphase A.C. source. A switch 8 is closed, when the contactor 3 is closed, to provide an input to a threshold circuit 5 which also has an input from the sensor and provides a signal to the pulse circuit 6 when the current sensor output exceeds the predetermined magnitude. A pulse shaping circuit is described, Fig. 2 (not shown), and provides a pulse shaped so that opening of the contactor does not occur under normal motor starting conditions or short transient overload conditions.

Title: Method and apparatus for activity-based collaboration by a computer system equipped with a dynamics manager
IPC: G06F15/00
Filed: 2002-01-17
Abstract: An activity-based collaboration system provides communication and other shared and mutual activities between individuals and small groups in shared private spaces, called "telespaces". In the system, participants or members of a telespace interact through personal computers, Internet appliances or other network-capable devices, which can communicate with one-another over a network, e.g., the Internet. Each telespace is an instantiation of an activity operable on each of the network-capable devices of members of the telespace. Each activity includes a tool for initiating data change requests (called "deltas") responsive to telespace member interactions, and a data-change engine, separate from the tool, for maintaining telespace data pursuant to a common data model, usually activity-specific, in memory. Each network-capable device also includes a dynamics manager, responsive to the deltas, for directing the data-change engine to make changes to the local copy of data.
