Title: Improvements in or relating to display arrangements
Inventor: ROBSON LESLIE JOHN
IPC: G08G5/00
Filed: 1961-01-03
Abstract: 967, 303. Electric selective signalling systems. AUTOMATIC SWITCHING Ltd. April 3, 1962 [Jan. 3, 1961], No. 193/61. Heading G4H. In a data transmission system a sequence of digits is transmitted by a dial, successive digits being registered at both the transmitter and receiver on three-bank uni-selectors DA, DB... DE, and immediately after each digit is registered the receiver transmits back to the transmitter a voltage that corresponds to the digit just registered where it is compared, by two polarised-relays PN, PP, with a similarly locally generated voltage and any disagreement causes an alarm to sound. To effect a transmission a reset/dial switch is first set to "dial". This picks up relay AV, which via contact AV1 picks up relay A at the receiver. This, in turn, results in the picking-up of relays B and BV and in the advance of digit selecting switches SS, at the transmitter and receiver, to their first position in readiness for the first dialled digit, The pulses of the first dialled digit are repeated, in particular at contacts AV1 and A1, from where they pass via switches SS2 to be registered on switches DA. While this is happening extra banks DA1 on the switches DA tap off voltages from a potential divider which are applied via switches SS1 to the polarised relays PN and PP. Any difference in these voltages causes one or other of these relays to pick up which causes a relay M to dropout and an alarm to sound. The switches SS are stepped to their second positions at the end of the first digit by means of relays CV and C. These relays both receive the dial pulses via contacts AV2 and A2 but they are arranged to be sufficiently slow-to-release so as not to drop-out until the end of the first digit, whereupon they advance digit switches SS. The system described also has the following features. After the first digit is dialled a relay E, at both the transmitter and receiver, picks-up and causes a "dial" lamp at the transmitter to flash intermittently to indicate that further digits have yet to be dialled, and a "data change" lamp at the receiver to light to indicate that the data is in the process of being changed. When the change of data is complete the lamp at the receiver is arranged to flash intermittently for about 45 seconds to draw a viewer's attention to the fact that the data has changed. If an error is detected by the polarised relays PN, PP, the relay M dropsout, which causes relays AV and A and then relays BV and B to drop-out and then the system reverts to its reset condition.

Title: Foaming agent concentrates
IPC: C08J9/06
Filed: 1965-01-05
Abstract: A foaming agent concentrate consists of a foaming agent dispersed in a normally solid amorphous propylene polymer, the weight ratio of foaming agent to polymer being 2:5 to 4:3.  The foaming agent is one which causes foaming by undergoing thermal decomposition or chemical reaction, e.g. azodicarbonamide, N,N1 - pentamethylenetetramine, benzene-1,3 - disulphonyl hydrazide, 4,41 - oxybis-(benzene sulphonyl hydrazide) and sodium borohydride.  The propylene polymer may be polypropylene or a copolymer of propylene with another 1-olefin, and preferably has a ring and ball softening point of 90 DEG  to 120 DEG C.  The concentrate is produced by mixing the foaming agent with a molten propylene polymer at a temperature below the characteristic temperature of the foaming agent, and between 90 DEG  to 140 DEG  C., and is suitably used to foam alkene and vinyl polymers, e.g. polythene, crystalline polypropylene, polystyrene and polyvinyl chloride.

Abstract: 1528272 Fuelling reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 2 Dec 1976 [7 Jan 1976] 00460/76 Heading G6C  A nuclear reactor of the kind comprising a reactor core submerged in a pool of liquid coolant contained by a primary vessel, e.g. a liquid metal cooled fast breeder reactor, is provided with an inclined shoot 13 for guiding a bucket 17 containing a fuel element assembly in to and out of the primary vessel and a shock absorber 16 at the foot of the shoot 13 for arresting a falling bucket. A vertical shaft 18 displaceable along its longitudinal axis has a horizontally pivoted hooked link 19 adapted to engage a radial projection 21 on the bucket 17 when in an inclined position and, by upward displacement of the shaft 18, to pivot the bucket 17 about its base into a vertical position (as shown in broken outline). A carrier 14 slidable along the shoot 13 under the control of a cable 15 carries the bucket 17. The carrier 14 is open at its uppermost side to enable the bucket 17 to be raised from its inclined position. To facilitate pivoting of the bucket 17 about its base, the base and the abutting surface of the carrier 14 are of complementary part-spherical shape and the pivot P is displaced from the axis of the shaft 18 so that the bucket 17 tends to fall into the carrier 14, the hooked link 19  merely controlling the fall of the bucket. In a particular embodiment, the shoot 13 is of  rectangular section and carries a pair of square  section carriers 14 each housing a bucket 17.  A fuelling machine withdraws a spent fuel element assembly from the core and deposits it in one of the buckets 17 when vertically  positioned, then engages a new fuel element  assembly disposed within a second bucket 17 alongside the first and transfers it to a vacant position in the core. A second inclined shoot (not shown) complementary to the first, enables spent fuel element assemblies to be transferred to a coolant-  containing storage chamber located within the concrete vault structure of the reactor.

As shown, the catalyst 12 which may comprise platinum and aluminium oxide is maintained at a temperature between 50 and 250C. in a cartridge and is connected at one end by pipes 16, 18, 22 and T-pieces 17, 21 to a multi-port valve 24 and at its other end by pipes 41, 43 and a T- piece 42 to a hydrogen indicating instrument 40 and a flow meter 47. The multi-port valve 24 has an inlet 27 connected to the gas mixture to be investigated, and an inlet 29 in connection with a hydrogen gas source. This gas source can be connected to the instrument 40 and flowmeter 47 by way of a valve-by-pass loop 37 and the catalyst and/or a further by-pass loop 44 for calibrating the instrument 40 and for ensuring that the catalyst is saturated with hydrogen. Subsequently, the gas mixture to be investigated can be connected to the catalyst when readings on the instrument 40 and flowmeter 47 are noted. Then the hydrogen source is re-connected to the catalyst for a predetermined interval and further readings are taken which allow the oxygen content of the gas mixture to be calculated. The instrument 40 may be a katharometer and the flowmeter 47 may comprise a graduated tube 50 along which gas is arranged to flow behind a soap film, the soap being housed in a deformable bulb 59.
