Title: Improvements in or relating to composite building boards
IPC: D21J1/08
Filed: 1937-04-02
Abstract: Composite building boards are produced by allowing core material to set in contact with a liner or liners which are coated or impregnated with uncured thermohardening resin which is dried without converting the resin to its final condition, and then subjecting the board to heat treatment to harden the resin. Either urea-, thiourea-, or phenol-formaldehyde resins may be used and they may penetrate the liner partially or completely.  In an example a white board was impregnated with a 60 per cent solution of a 50 per cent resin syrup containing 1 1/2 molecular proportions of formaldehyde to 1 of urea and catalysed with 0,1 per cent sulphuric acid.  In a second example the core comprised in addition 15 parts of resin syrup similar to that used for impregnating the liners.  The resin syrups described in Specification 491,882 may also be used and acid catalysts are added to accelerate the resin condensation.ALSO:Composite building-boards are produced by allowing core material to set in contact with a liner or liners which are coated or impregnated with uncured thermo-hardening resin which is dried without converting the resin to its final condition, and then subjecting the board to heat treatment to harden the resin.  The core material may comprise plaster, cement, &c., and the liners may be of paper, pulpboard, &c.  The board may be formed in known manner by passing the liners, with the core material between them, between rollers.  Either urea-, thiourea-, or phenol-formaldehyde resins may be used and they may penetrate the liner partially or completely.  In the latter case and additional paper liner may be used next to the core.  The liner may be decorated by plain or printed colours or by embossing.  In an example, a white board was impregnated with a 60 per cent solution of a 50 per cent resin syrup, containing 1 1/2 molecular proportions of formaldehyde to 1 of urea and catalysed with 0,1 per cent sulphuric acid.  The board was dried at a low temperature leaving the resin uncured and applied on both side of a core consisting of 100 parts by weight of Plaster of Paris, 10 parts of sawdust, and 55 parts water.  The formed board was passed through a drier whose inlet was at a temperature of 150 DEG  C. and outlet at 65 DEG  C., and the board was then ironed at 140 DEG  C. and polished.  In a second example the core comprised in addition 15 parts of resin syrup similar to that used for impregnating the liners.  The resin syrups described in Specification 491,882, [Group IV], may also be used in the present invention and acid catalysts are added to accelerate the resin condensation.  The final board may be baked for 6 hours at 60 DEG  C. to improve its water-resistance.

IPC: F16J15/34
Filed: 1967-03-01
Abstract: 1,145,448. Mechanical seals. CRANE PACKING Ltd. 8 Jan., 1968 [1 March, 1967], No. 9660/67. Heading F2B. In a mechanical seal the axially movable sealing member 4 has a frusto-conical surface in resiliently stressed engagement with a complementary tapered surface of an axially fixed carrier member 6 whereby the said members tend to slide axially apart thereby urging the member 4 into facial sealing contact with its co-operating axially fixed sealing member or seat 5. As shown for a rotary shaft 2, the seat is clamped to the pump housing 1 and the member 6 is secured to the shaft and has a tapered spigot which is forced into a tapered counterbore in the sealing member 4, the resulting hoop stress in the member 4 causing it to be urged against the seat 5. Both the members 4 and 6 may be of P.T.F.E. and may be reinforced with a filler such as glass fibre confined, in the case of member 4, to the sealing face region and, in the case of member 6, to the part secured to the shaft. Alternatively, one of the members may be of P.T.F.E. and the other of a rigid material, e.g. metal. The taper angle of the contacting surfaces 8 must be greater than the friction angle for the materials used. In a modification, the sealing member may have an external taper surface received in a tapered counterbore in the carrier member.

Title: Improvements in and relating to circuits embodying electronic counters
Inventor: BAILEY CHRISTOPHER EDMUND GERV
IPC: G06V10/24
Filed: 1957-03-25
Abstract: 850,583. Comparing digital data. SOLARTRON ELECTRONIC GROUP Ltd. March 17, 1958 [March 25, 1957], No. 9771/57. Class 106(1). Apparatus adapted to be fed with successive groups of pulses and to determine the maximum or minimum number of pulses in a group, comprises two electronic counters and a computor which, after each group of pulses is received, causes that counter storing the higher or lower count to be reset and thereafter activated to count the pulses in the next group. The arrangement shown forms part of a character-reading apparatus as described in Specification 850,581. During each line of a scan, one of the counters 60, 61, determined by the state of bi-stable device 64, counts the pulses received from clock generator 18 until a black element is sensed which triggers bi-stable device 63 to inhibit the counter input gates 65, 67. The voltages on lines 73, 74, which correspond to the values registered on the counters, are then compared in circuit 62 which primes gate 66 or 69 according to whether the higher count is registered in counter 60 or 61. Suppose e.g. that counter 61 has counted the last group of pulses. If this counter registers the higher count, the comparator 62 and device 64 activate gate 69 and thus inhibit associated gate 76; an interline pulse received from circuit 45 then passes through delay network 79 and gate 70, opened by device 64, thus resetting counter 61. If, however, counter 61 registers the lower count, neither of the gates 66, 69 is activated and neither of gates 75, 76 is inhibited; the interline pulse is therefore passed to both inputs of device 64 which is then switched over, thus opening gate 67 to cause counter 60 to be reset by the delayed pulse from 79. When the scanning process is completed, one of the counter outputs A, B will represent the smallest number of blank elements counted (the other counter registering zero), and will thus indicate the number of blank elements separating the most " northerly " point on the character being scanned from the north of the scanning raster. A slightly modified arrangement (Fig. 2, not shown) similarly obtains an indication of the most southerly point. The apparatus of the invention may be employed also for determining the maximum or minimum values of a graph obtained, e.g. from a spectrometer, and scanned photo-electrically, or for determining the maximum or minimum amplitude of pulses. The counter outputs may be recorded, e.g. on magnetic tape or by a printer.
