Title: Self-crosslinking interpolymers
IPC: C08F2/22
Filed: 1963-11-05
Abstract: Self-crosslinking interpolymers are prepared by polymerizing in aqueous emulsion at 37-70 DEG  C. a monomer mixture comprising 0.9 to 2.7 mole per cent of glycidyl acrylate, 2.9 to 15.4 mole per cent of styrene, from 80 to 94 mole per cent of ethyl acrylate, and from 0.8 to 5.5 mole per cent of acrylic and/or itaconic acid, the total emulsion comprising 45-65% by weight of water.  The emulsifying agent used is preferably nonionic but an anionic emulsifier may additionally be present; various examples of these are listed. Suitable polymerization catalysts include alkali metal and ammonium persulphates and perborates, hydrogen peroxide, t.-butyl or cumene hydroperoxide and t.-butyl perbenzoate; these are preferably used together with a reducing agent such as bisulphites, thiosulphates, hydrosulphites and salts of metals that can exist in more than one valency state, e.g. sulphates of Co, Fe, Ni or Cu. Monomer and catalyst components may be added during the course of polymerization. After polymerization the pH of the emulsion is desirably adjusted to 4.0 to 7.5 with a suitable base, when the emulsion is to be used, for example, in coating applications.  Coatings produced therefrom cross-link on air-drying although the process can be accelerated by the application of heat.  The polymer products are also suitable as binders for non-woven fabrics and for pigments.ALSO:Self-crosslinking interpolymers containing 0.9 to 2.7 mole percent of units of glycidyl acrylate, 2.9 to 15.4 mole percent of units of styrene, 80 to 94 mole percent of units of ethyl acrylate and 0.8 to 5.5 mole percent of units of acrylic and/or itaconic acid are suitable for use as binders for non-woven fabrics (unspecified).ALSO:Self-crosslinking interpolymers containing 0.9 to 2.7 mole per cent of units of glycidyl acrylate, 2.9 to 15.4 mole percent of units of styrene, 80 to 94 mole percent of units of ethyl acrylate and 0.8 to 5.5 mole percent of units of acrylic and/or itaconic acid are suitable for use as backcoatings for textile fabrics such as upholstery fabrics and rugs.  The interpolymer may be applied in the form of an aqueous emulsion using conventional means such as brushing, spraying, dipping, roller-coating or casting.  The emulsifier present is preferably nonionic although an ionic agent may additionally be present.  The emulsion is stabilised by adjusting its pH to 4.0 to 7.5.  Conventional additives may be present, e.g. binders, filler, filler dispersants, wetting agents, thickeners, plasticisers and anti-foams.  Crosslinking of the coating takes place simply on air drying although the process may be accelerated by the application of heat.

Title: Safety apparatus for use in controlling a railway vehicle
IPC: B61L3/00
Filed: 1962-11-19
Abstract: 1,021,835. Train stopping arrangements. MASCHINENFABRIK OERLIKON. Nov. 19, 1962 [Nov. 24, 1961], No. 43726/62. Heading B7N. A safety device for a railway vehicle controlled by an unaccompanied driver includes means for producing warning signals and for stopping the train if a dead man's handle is released and for producing the same action each time the train has travelled through a predetermined distance unless the driver takes preventive action. The device responds, quickly to the first condition and slowly to the second. Warning device 10 and switching circuit 11 for stopping the train can be operated by associated bi-stable circuits 8, 9 which receive an input from OR gates 5, 6 controlled by the output of AND gates 3, 4 and the output b from the high stages of a distance measuring counter 7 suppled from. a pulse generator (not shown). Zero output on contact 1 of a dead man's handle in its operated position blocks the AND circuits 3, 4. If the handle is held operated the distance count eventually reaches the high stages b of the counter when a signal on line 17 passes via OR gate 6 and triggers bi-stable circuit 9 to a state in which it operates device 10. If the driver takes no action the following signal on line 18 actuates the train stopping circuit via OR gate 5 and bi-stable circuit 8. If, however, the driver partially releases the handle a positive signal on contact 1 triggers monostable circuit 2 which supplies an output via OR gate 15 to reset the counter. Should the handle be released negative potential on contact 1 opens AND gates 3 and 4 and signals from the low stages a of the counter operate the warning and stopping circuits via OR gates 5 and 6 and bistable circuits 8 and 9.

Title: Toaster
IPC: A47J37/08
Filed: 1968-09-13
Abstract: 1,236,267. Electric toaster. SUNBEAM CORP. 13 Sept., 1968 [15 Sept., 1967], No. 43746/68. Heading A4D. A "pop-up" type toaster 20 is characterized by pneumatic means for releasably holding the bread carriage 45 in its lower toasting position, said pneumatic means including a vertically extending cylinder 62 from which the air is expelled by the piston 63 when the bread carriage 45 is lowered and which releases the bread carriage by admitting air to the cylinder, due to the movement of a bimetallic strip, at the end of the toasting cycle. The air is displaced from the cylinder 62 first through the aperture 81 (not shown), and when the piston 63 has passed said aperture in the cylinder wall, through the valve port 80 (not shown). The lower valve port is blocked by a horizontally movable pad 83 (not shown) and a partial vacuum is created which holds the bread carriage in the toasting position against the action of the return spring 53. A bimetallic strip is actuated by the temperature of the bread slice which causes the pad 83 (not shown) to be removed from the valve port 80 (not shown), thereby allowing air into the cylinder 62 and the bread carriage 45 to return to its upper position. The bread carriage may be returned to its upper position from the lower position at any time during toasting by operating the handle 58. The toasting time may be pre-set by the knob 125 which affects the position of the bimetallic strip. The performance of the present invention involves the use of the invention described and claimed in British Patent Specification 1,125,184.

Abstract: 450,576. Photometric apparatus. BOLTON, E. R., and WILLIAMS, K. A., 6, Milner Street, Chelsea, London. April 26, 1935, No. 12586. [Class 97 (i)] In apparatus for measuring the colour of transparent or opaque substances by a photo-electrical measuring device, the infra red or other undesired rays transmitted by the filter are prevented from impinging on the light-sensitive element. For transparent liquids, light from a lamp 2 is condensed by a reflector 3 and lens 4 into a beam which passes through an adjustable stop 5 into a cell 6 fitted with transparent ends 6a and containing a liquid such as a solution of copper sulphate to absorb infra-red rays. The light then passes through a colour filter 7 into a tray 10 movable on rails 1i and containing two adjacent cells 9, in one of which is a standard liquid and in the other the liquid under examination, each liquid being brought alternately into the beam by sliding tray 10 on the rails. The light finally impinges on a photo-electric cell 11 connected to a galvanometer 12, the reading of which is taken for each liquid alternately, thus allowing the absorption of the examined liquid to be compared with that of the standard. The process is repeated with different colour filters 7 and the spectral absorption of the liquid determined. The scale of the galvanometer may be calibrated to read directly the percentage absorption of light by the liquid, the reading of the standard liquid being first brought to a predetermined value by means of stop 5. For opaque substances the amount of light reflected by the substance may be compared with that reflected by a standard surface such as one of magnesium oxide.
