Title: An improved anti-roll and shock absorber assembly for vehicles
IPC: B60G15/06
Filed: 1936-10-29
Abstract: 488,091. Vehicle spring-suspensions. MONROE AUTO EQUIPMENT CO. Oct. 29, 1936, No. 29481. Convention date, April 6. [Class 108 (ii)] In a vehicle-suspension system of the kind in which a stabilizing device in the form of a transverse torsion rod 19, Fig. 1, is combined with shock-absorbing means, the torsion rod is mounted upon either the spring or unsprung assembly and has its ends cranked and connected to the other of such assemblies, while a single shock-absorber is employed having one end connected to the torsion rod and the other end to one of the assemblies. In the arrangement shown the side arms 21 of the stabilizer are connected by means of links 22 to clamping plates 18 for the main suspension springs 16, the joints at the ends of the links 22 preferably being of an elastic nature, and the torsion rod 19 being also mounted in rubber blocks 28 in clamps 29 secured to the frame 10. The single shock-absorber 31, which may, as shown, be of the kind described in Specifications 481,869 or 481,935, is secured at its lower end by an arm 34 to the axle 14 and at its upper end to an arm 36 fixed to the centre of the rod 19, the arm 36 extending in the opposite direction to the arms 21. In a modification, the arm 36 is mounted to extend in the same direction as the arms 21, while in a further construction, Fig. 7 (not shown), the shock-absorber is connected between the torsion bar and a sprung part of the vehicle. The Specification as open to inspection under Sect. 91 comprises also modifications in which two shock-absorbers are combined with the torsion bar. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to signal operated visual indicators for use in wirelessnavigation aiding systems
IPC: G01S1/02
Filed: 1934-10-15
Abstract: 429,001. Directive wireless signalling; valve circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Oct. 15, 1934, No. 29493. Convention date, Oct. 13, 1933. [Classes 39 (i) and 40 (v)] In an aerial navigation system, one or more short wireless impulses are caused to give corresponding visible indications, of longer duration, by utilizing " triggered " glow-discharge lamps. When an aeroplane is approaching the aerodrome f along a radio guideline C, Fig. 1, two vertical beams b, a of different wave-length, or differently modulated, may be used to give the pilot an indication of his height and distance. In order to allow the transient incoming signal to produce a more lasting indication, the last stage d of the wireless receiver on the aeroplane is coupled through tuned circuits k1 k2, to two " triggered " glow-lamps g<1>, g<2>. The threshold voltage for the lamps is supplied from the source S which is " stabilized " by a similar glow-discharge device St in series with a resistance r. The glow-lamps g<1>, g<2> are coated with red or yellow varnish to prevent them from reacting on each other, and have differently-shaped cathodes or different gasfillings, so that one is readily distinguished from the other. The tuned circuits kl, k2 may be replaced by band-pass filters.

Abstract: 1,176,768. Sampling particles. O. WEISS. 21 June, 1968 [27 Sept., 1967], No. 29699/68. Heading BIT. [Also in Division El] In a method of serial prospecting by the collection of airborne mineral particles, the particles are collected on a thread of synthetic polymer material. The thread may be composed of a monofilament or staple fibres of nylon, a polyester, a polyolefin, or an acrylonitrile polymer. One or more threads may be attached to a tow line suspended from an aircraft and carrying ballast weight. Alternatively the thread may be wound about a frame carried by the tow line. While one tow line is being winched into the plane to replace the thread, a second tow line is dropped out. The particles may be removed from the thread for analysis by passing the thread between overlapped portions of a folded pad of a nylon micro web, or of alpha-cellulose or polyolefin fibres. Alternatively the thread may be passed through a central bore of a cylinder with the particles being deposited primarily on the inlet end of the cylinder which is then cut off. A split cylinder may be used.

Title: Power measuring and fuel leakage detection system in a nuclear reactor installation
IPC: G21C17/04
Filed: 1972-06-26
Abstract: 1356511 Monitoring reactors WESTINGHOUSE ELECTRIC CORP 26 June 1972 [12 Aug 1971] 29774/72 Heading G6C A nuclear reactor installation (Fig. 1, not shown) includes a power measuring and fuel leakage detection arrangement in which a gamma detector 10 provides a first signal responsive to gamma activity in the coolant (e.g. in a hot leg 60 of the coolant piping 12), a neutron detector 14 provides a second signal responsive to neutron activity in the coolant and in which first and second compensating means including amplifiers are arranged respectively to compensate the first signal for the component contribution from failed fuel so as to provide a first compensated signal proportional to reactor power and to compensate the second signal for the component contributions from N<SP>16</SP>, N<SP>17</SP> and uranium surface contamination so as to provide a compensated second signal indicative of failed fuel within the reactor. Thus, the output of channel 16 remains proportional to N<SP>16</SP> activity, and hence reactor power, independent of fission products arising from failed fuel. Where total transport time in the coolant loop is too short to permit complete decay of the monitored activity, a build-up compensation system is employed in the outputs of the detector circuits, as shown. An alternative compensation arrangement is described (Fig. 3, not shown), and as a further alternative, digital techniques can replace the use of analogue circuits. In the installation, which has a domed concrete outer containment (72), the reactor vessel (50) is surrounded by a concrete blast shield (74) outside which the steam-generating sets are arranged. The reactor is of the pressurized water type. A single detector having, respectively, gamma- and neutron-sensitive sections may be used instead of two detectors.

Title: Improvements in or relating to the manufacture of maleamic acid
IPC: C07C235/00
Filed: 1946-10-08
Abstract: Maleamic acid is produced by passing gaseous ammonia into a solution of maleic anhydride in an inert organic solvent, the ratio of maleic anhydride to solvent at the commencement of the reaction being at least 1 : 10 by weight and the temperature of the reaction being below the temperature at which the maleamic acid resinifies. Preferably the ratio of maleic anhydride to solvent is about 1 : 5 by weight and the temperature of reaction between 50 DEG  C. and 100 DEG C.  The solvent should be one in which maleic anhydride is readily soluble yet maleamic acid is insoluble or only sparingly soluble and is preferably an aromatic hydrocarbon or a chlorinated hydrocarbon but any inert organic solvent may be used.  In four examples dry gaseous ammonia is passed into a solution of maleic anhydride in xylene, trichlorethylene, tetrahydronaphthalene and dioxane respectively, in a flask fitted with a reflux condenser and a mechanical stirrer.  The passage of ammonia is continued until it is evolved from the top of the reflux condenser, the reaction being then stopped and the precipitate filtered off, washed and dried.  Benzene and chloroform are also mentioned as solvents. Specification 597,590 is referred to.

Title: An improved process for defecating and purifying sugar-juices
IPC: C13B20/00
Filed: 1930-10-08
Abstract: Raw sugar juices are defecated and purified by treating them with the optimum economical quantity of lime calculated to produce an effective precipitation of the impurities and to ensure a ready separation thereof on subsequent filtration, the addition being made at a low temperature and followed by a rapid heating.  The juice is then treated with an electrolyte, such as aluminium sulphate, in an amount adapted to fix and disperse the remaining colouring matter and colloidal impurities and the necessary quantity of a suitable acid reagent is added to impart the requisite degree of alkalinity required for the usual subsequent working after filtration.  Thus, lime in amount of 0,5 per cent of the weight of fresh beet is added to raw juice at 40-50 DEG  C. and the juice is then heated to about 75 DEG  C.  Aluminium sulphate in amount of 0,3 per cent of the weight of fresh beet is added, and the subsequent acid treatment is effected by calcium phosphate, carbon dioxide or sulphur dioxide so as to bring the pH value of the juice to 7,5-8 if the juice is to be concentrated and sulphited or to 7 if the juice is only to be treated with decolorizing carbon.
