Polyacrylic latex, polyvinyl-alcohol and -acetate are specified as resins. Further additives are epoxy oils and aliphatic silanes.
Patent GB-506927-A (GB)
Abstract: 506,927. Electric signalling systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and SAVILLE, W. Dec. 6, 1937, No. 33737. [Class 40 (i)] In a mine signalling system employing a pair of signalling leads, the haulage is adapted to be stopped automatically in response to a signal but cannot be restarted by another signal until an operation has been performed by the engineman, who is enabled to judge whether the two signals came from the same locality. When the two signalling leads, extending from terminals 11, 12 along the haulage way, are connected, relay L operates, causing relays TD, LA to operate,in turn so that S falls away, breaking the driving control circuit 15, 16. MA is energized over contacts ONW causing the driving magnet WM to step switch W until a Wheatstone bridge arrangement of which banks W1, W4 form the variable arm is balanced, polarized relay BR operating to stop WM and lock up MW, a white light being shown from switch banks W3, W6. Switch R now steps round until it finds the potential from wipers W2, W5, whereupon CR oporates to stop the switch, a red. light being shown in a corresponding position to the 'white one, and relay MR locking up to keep the switch stationary. The engineman operates the white light cancelling key WCK, completing a homing circuit for switch W, RCK being ineffective if operated before WCK. When the start signal is received, the switch W is again positioned and the engineman starts the engine if the white lamp energized is sufficiently close to the red lamp. The start signal may consist of two pulses and if the first ceases before switch W has rotated sufficiently, the switch restores, but PO having operated has cut out TD, so that the second pulse pulls up LA immediately to prevent delay in the starting of the switch. The engine is restarted by the engineman lifting the armature of S, completing the locking circuit, and the circuit over wires 15, 16. The signalling leads may also be used for code signalling using short pulses which are insufficiently long to operate TD.

Title: Improvements in apparatus for supplying fibres to a textile machine
IPC: D01G23/08
Filed: 1964-12-15
Abstract: 1,096,886. Feeding fibres to machines. F. REITERER and L. WINDISCH. Dec. 15, 1964 [Dec. 21, 1963], No. 51040/64. Heading DIN. Fibres supplied to a vertical shaft forming a feed element of a textile machine are conveyed in an air stream from which they are separated while being maintained in open condition by extracting part of the air from the air stream at the upper end of the vertical shaft. The initial air stream carries fibres through a duct 5 to an area immediately above the vertical feed shaft and which is partially bounded by screens 6, 6' within a compartment from which air is positively exhausted through ducts 7. Adjacent to the screens the cross-section of the duct 5 increases considerably, resulting in a reduction in the velocity of the air stream and a slowing of fibre movement. The rate at which air is extracted through the ducts 7 is slightly less than the rate at which it is supplied through duct 5, in consequence of which fibres tend to float within the area bounded by the screens until removed by a flap 11 that is mounted to rotate through 360‹ and to reverse its movement when in its lower vertical position. Mounted on the same shaft as flap 11 for partial rotation therewith through a slipping clutch arrangement is another flap 12 which has the effect of partially closing the screen area from the vertical feed shaft beneath. This flap 12 is also utilised as a detector which is affected by the presence of fibres at the top of the feed shaft in order temporarily to cut off the fibre supply from a preceding machine. An arrangement of push buttons 14, 14', 15, 15' and stops 16, 17, 19 associated with the two flaps are effective to this end.

Title: Opening of paper constructions
IPC: B65D27/32
Filed: 1972-11-07
Abstract: 1415674 Unpacking THOB DAHL Inc 7 Nov 1972 51335/72 Heading B8C [Also in Division B6] In a method of separating two parts of a piece of paper, a sensitizing agent is applied to a portion of the paper and a developing agent is added to release a degrading agent from the developed sensitizing agent to degrade the portion. The method may be applied to opening of three edges of four-edged envelopes. The sensitizing agent, which may be applied before or after envelope manufacture at the fold lines by a roll, spray or pad, e.g. in a printing process, may be a higher molecular weight alkyl sodium sulphate, e.g. sodium lauryl sulphate, but is preferably a lower molecular weight compound, e.g. 10% n-propyl sodium sulphate in an isopropyl alcohol solution. An aqueous solution may alternatively be used, and wetting and viscosity control agents employed. The developing agent is a strong organic acid, e.g. acetic or oxalic acid applied by roll, spray or pad and preferably dried by an air blast. Subsequent heating hydrolyses the alkyl sodium sulphide releasing sulphuric acid which degrades the paper which may be removed by a rotatable nylon brush.

Filed: 1974-12-05
Abstract: 1446800 Aerials TRW Inc 5 Dec 1974 [6 Dec 1973] 52649/74 Heading H4A An artificial dielectric unit 16, Fig. 4, which is dimensionally stable over a pre-determined range of temperature, comprises a substantially rigid ring 22 having a dielectric material membrane 20 so pre-tensioned across it that throughout said range the membrane remains under tension without its maximum permissible stress value being exceeded. Electromagnetic wave obstacle means are carried by the membrane 20, either in the form of an array of discrete conductive areas (phase delay type), or of an array of apertures in a conductive coating (phase advance type). The membrane may be made of plastics film, and the ring of a material having a coefficient of thermal expansion which is either substantially equal to that of the membrane, or differs therefrom. The two are bonded together so as to obtain the desired result. If their coefficients of thermal expansion are not the same, bonding may take place at a temperature which is outside the pre-determined range, and with the membrane in a non-slack and non-tensioned condition. The pre-tension arises as the unit cools down or heats up to a temperature within the pre-determined range. A lens 10, Fig. 7, comprises a stack of units 16, which are joined together by means of bolts 18 through holes provided in the rings. As shown, the patterns of obstacles are so graded as to form a collimating lens for radiation from a horn 14. Outer protective units 40 are similar to the units 16, but their membranes have no electromagnetic wave obstacle means.
