Title: Process for the manufacture of non-foaming resin dispersions with prolonged storability
IPC: C08J3/03
Filed: 1964-09-28
Abstract: Non-foaming emulsifier-containing resin dispersions are obtained by adding 2.5 to 20% based on the weight of the solids content of the dispersion of a defoaming agent containing a weakly hydrophilic group bound to a hydrophobic fatty alkyl group, a hydrophobic fatty acyl group or a hydrophobic alkaryl group to the emulsifier-containing resin dispersion.  The defoaming agent may be added before or after polymerization.  Defoaming agents may be oxyethylated fatty alcohols, oxyethylated fatty amines, oxyethylated alkyl phenols, oxyethylated fatty acids, addition products of polypropylene oxide with ethylene oxide, which per mol contain 2 to 30 mols of ethylene oxide, or tertiary esters of ortho-phosphoric acid in which the alcohol derived groups, which may be the same or different, each containing at least 5 carbon atoms, or mixtures of any of these compounds.  The emulsifiers are conventional anionic, cationic,non-ionic or high molecular weight surface-active compounds. Resins specifically exemplified are:-copolymers of butyl acrylate/methyl methacrylate/acrylic acid; butyl acrylate/methyl acrylate/acrylic acid; ethyl acrylate/methyl methacrylate; vinyl benzene/ethyl hexyl acrylate/acrylonitrile/acrylic acid; vinylidene chloride/methyl methacrylate / methyl acrylate; vinylidene chloride/ethyl hexyl acrylate/butyl acrylate; vinylidene chloride/acrylonitrile/methyl methacrylate; butadiene/styrene; butadiene;acrylonitrile; ethylene/propylene; vinyl acetate/ethylene; vinyl chloride/butyl acrylate/acrylic acid; polymers of polyvinyl acetate and polyvinyl propionate and natural latex.ALSO:Concrete and mortar are rendered impermeable to moisture by the addition of a non-foaming emulsifier-containing resin dispersion containing as defoaming agent a compound having a weakly hydrophilic group bound to a hydrophobic fatty alkyl group, a hydrophobic fatty acyl group or a hydrophobic alkaryl group (see Division C3).  The examples describe the effect of the defoamed dispersions on mortar comprising 1 part by weight of Portland cement, 3 parts by weight of sand having a grain size of up to 3 mm. and mixing water and a lime mortar comprising 1 part by weight of white lime hydrate, 3 parts by weight of sand having a grain size up to 3 mm. and mixing water.

Title: Flat tire warning device
IPC: B60C17/01
Filed: 1960-11-17
Abstract: 907,277. Tubeless safety tyres. GOODYEAR TIRE & RUBBER CO. Nov. 17, 1960 [April 4, 1960], No. 39484/60. Classes 144 (1) and 144 (2). In a tubeless safety tyre embodying either an internal diaphragm 5 anchored at its edges 6 to the tyre beads 7, or an inner tube, which divides the tyre space into separately inflatable inner and outer compartments 8, 9, the outer periphery of the diaphragm 5 or tube which provides for support of the tyre tread in the event of deflation of the outer compartment is constructed so as to provide at least one radial protuberance in operation sufficient to cause vibration of the wheel and thereby give warning of the deflation. The diaphragm or tube is constructed of stretch-resistant material such as parallel cord plies, and the protuberance may be provided by the use of cords 14 around at least a 120 degree arc, of greater stretchability than those 13 used in the remainder of the diaphragm circumference. Such a construction provides a uniform cross-section when the pressures are equal in the compartments 8, 9 but permits stretch of the diaphragm to the contour 15, on deflation of the compartment 9, over that arc formed by the cords 14. Alternatively, the diaphragm or tube may comprise sections of hard rubber of greater stretchability than cord plies used in the intervening sections, or alternate sections of single and double cord plies. In a further arrangement shown in Fig. 3, the diaphragm 16 is moulded with diametrically opposed permanent depressions 17. The depth of the protuberances in all cases may be from 3/8 to 3/4 of an inch.

Abstract: 1531930 Photo-electric defect detectors ARGUS ELECTRONIC VOLE IVERSEN 27 Sept 1976 [3 Oct 1975] 40058/76 Heading G1A To detect various forms of holes in a moving knitted fabric three photo-detectors are arranged behind a slot which is disposed transverse to the direction of motion, and the outputs of the detectors are summed to indicate defects extending across all three detectors, and are also compared to indicate defects adjacent only one or two of the detectors. In Fig. 1 the signals from detectors 1-3 are all fed to operational amplifier 12 where their sum is found; they are also each fed to operational amplifiers 4-6 where each is compared with the mean of the other two. After rectification at 7-9 and summation at 10 the result is displayed at 11. If a hole extends across all three detectors the signals on all the inputs to 4-6 are equal and cancel, so the only output is from 12; for any other sort of hole there will be an output at 11. Circuit details are given, Figs. 2, 3 (not shown), as are setting-up procedures.

Abstract: 1437078 Measuring frequency digitally; alarm senders GENERAL ELECTRIC CO Ltd 31 Aug 1973 [7 Sept 1972] 41441/72 Headings H3H and H4K [Also in Division G1] A waveform is analysed to derive a histogram of its frequency spectrum by timing intervals between successive positive (or negative) going transits of the waveform through a reference level for each of a plurality of different reference levels covering the amplitude range of the waveform, and counting, in respective counters, the occurrences of timed intervals within each of a plurality of time ranges. The reference levels may be monitored for transits simultaneously or consecutively, for which purpose a monotonically increasing staircase or ramp reference signal may be employed.  As shown in Fig. 5, a ramp reference signal R is compared with the input waveform W, each positive going transit of R by W causing a clock 14 to be reset and, after a delay M2, counter 18 to be cleared, thereby to begin timing a new interval. The contents of the counter for a just completed interval are strobed out through gates DG1 ... DG7 and bi-stables DT1 ... DT7 to open an appropriate one only of gates GC1 ... GC6 depending on the range in which the interval falls to increment by 1 the associated counter OC1 ... OC6. Latches OL1 ... OL6 enable respective gates OG1 ... OG6 when their respective counters have been incremented by preset amounts and decoder 26 gives an output signal if appropriate patterns of gates OG1 ...

The invention may be applied to apparatus for automatically sending messages recorded on a tape loop to a series of telephone numbers.
