Title: Device for automatically detecting abnormal conditions in vehicle tyres
IPC: B60C23/02
Filed: 1972-10-31
Abstract: 1409320 Low pressure indicator for tyres NISSAN MOTOR CO Ltd 31 Oct 1972 [22 Nov 1971] 50102/72 Heading B7C [Also in Division G1] To detect abnormal conditions in tyres of a wheeled vehicle, i.e. too low air pressure and/or excessive tyre temperature, a sensor comprising a pressure switch and a temperature switch is arranged on each tyre assembly, a secondary coil is secured concentrically on each axle of the vehicle for rotation therewith and is electrically connected to its corresponding sensor, a primary coil is rigidly secured to the vehicle frame and concentrically with respect to its corresponding secondary coil so that each primary coil exhibits a marked inductance change upon the abnormal conditions being sensed, a detector is connected to the primary coils to detect any marked inductance change, and an alarm device is provided to warn the driver of any abnormal condition detected. As shown in Fig. 2, each sensor 10 consists of a pressure-sensitive switch consisting of a piston 25 provided with a movable contact 33, and a fixed contact 32, and a PTC thermistor 31. When the air pressure falls below a predetermined level, the switch opens and when the temperature exceeds a preset level the thermistor acts like an open switch. The thermistor and switch are connected in series with a respective secondary coil 41 mounted on the axle 42, see Fig. 6. The respective primary coil 40 is mounted on a housing within which the axle rotates. To detect marked inductance changes, Fig. 8 (not shown), each primary coil is provided with pulses via respective resistors, and the voltage between each resistor and its respective primary coil is compared in a respective comparator with a reference level to provide a pulse when the voltage exceeds the reference level. The outputs of the comparators are connected to respective AND gates whose other terminals are connected to a source of constant duration reference pulses. Any marked inductance change in a primary coil causes the corresponding comparator output pulses to increase thereby providing an output from the corresponding AND gate. The AND gates are connected to an OR gate whose output is applied to an integrator. The integrator output is applied to a comparator which produces an output to activate an alarm, e.g. a light, when the integrated signal exceeds the comparator reference. A sensor for the spare tyre is also connected to the OR gate via a switch. Alternatively, inductance changes may be detected with an oscillation circuit utilizing LC resonance in combination with a frequencyto-voltage converter. Further an A.C. bridge circuit can be employed.

Title: Continuous method for making silica sols
IPC: C01B33/143
Filed: 1963-12-20
Abstract: A continuous method for producing colloidal silica sols comprises repeating in a continuous manner the steps of: (a) contacting an aqueous solution of alkali metal silicate containing at least 5% by weight solids expressed as SiO2 with a resinous body of an acid-regenerable cation-exchange material in the hydrogen form by flowing the solution through the resin; (b) collecting the resultant acid silica sol effluent; (c) terminating the flow of alkali metal silcate solution when the capacity of the resin is exhausted as indicated by a first drop in conductivity of the effluent; (d) backwashing the resin with water to remove entrapped unreacted alkali metal silicate; (e) regenerating the resin with a mineral acid to an original cation-exchange capacity efficiency of at least 60%; and (f) rinsing the resin with water which is free of ions causing hardness in order to free the resin of residual acid.  It is preferred that the silicate solution contains from 5 to 8% by weight solids expressed as SiO2; that the flow of silicate solution is terminated when the conductivity of the effluent first measures between 150 and 400 mmhos; that backwashing is for a time sufficient to reduce the alkalinity of the backwash effluent to below 25 grains per gallon when measured as CaCO3; that the acid regenerant is dilute sulphuric acid; that rinsing is for a time sufficient to reduce the acidity of the rinse effluent to below 20 grains per gallon when measured as CaCO3; and that, in the rinsing, which may be in two stages, the rate of flow of water is sufficient firstly to displace the acid from the resin and latterly to scour the resin. The silica sol may be concentrated by known methods, for example those disclosed in U.S.A. Specifications 2,574,902 and 2,929,790.

Title: Alloy target for x-ray tubes
IPC: C22C27/04
Filed: 1973-11-02
Abstract: 1448488 Mo-W alloys GENERAL ELECTRIC CO 2 Nov 1973 [2 Nov 1972] 51059/73 Heading C7A [Also in Division H1] At least the target area of an x-ray tube anode (e.g. rotating type) consists essentially of a W-Mo alloy, the W being in amount 5 to 35% by wt. (e.g. 30%). Mo produces characteristic radiation at lower voltages than W, as required for diagnostic mammography. The W modifies the ductile - brittle transition temperature and reduces severe cracking at high current operation. Clustering of atoms rather than short range atom order provides increased ductility at low temperatures by removal of interstitial elements (e.g. C and O). The entire anode need not be made of the Mo-W alloy; the base may comprise other materials such as, W and Mo for example.
