Title: Tyre pressure monitoring arrangement
IPC: B60C23/00
Filed: 1974-08-23
Abstract: 1484341 Indicating abnormal pressures in vehicle tyres SAFETY RESEARCH & ENG CORP 23 Aug 1974 [4 Dec 1973] 37239/74 Heading B7C An arrangement for monitoring the pressure in at least one pneumatic tyre of a motor vehicle, comprises a respective pressure responsive signal generating device for mounting on the or each wheel, which device, in use, generates no signal when the tyre pressure lies within a predetermined range and generates a sonic or ultrasonic signal when the pressure changes to a value outside the range, a respective signal sensing means, associated with the or each device and adapted to be mounted on the vehicle, for sensing a signal generated by the device, and alarm means operatively connected with the or all the sensing means and adapted to provide an alarm in response to the detection of a signal by the or any of the signal sensing means. When in use on a vehicle, a device is fitted to each wheel (including the spare) and a sensor is mounted on the vehicle body adjacent each wheel. Upon the pressure in one tyre becoming outside the predetermined range visual and audio warning devices (DS1) (B1) will be activated provided that the ignition switch (147) is on, by a circuit (140) (Fig. 2, not shown). Even when the ignition switch is off, the circuit will still be conditioned, if the pressure of a tyre becomes outside the range, so that upon switching the ignition on, the driver will have an immediate indication of an abnormal pressure. Different warning lights may be provided for the nearside and offside wheels and different devices, e.g. producing different frequencies may be associated with the nearside and offside wheels. As illustrated the or each device comprises a housing 18 accommodating a piston 34 and a stem 32 attached to the piston and including ports 40 providing a sonic or ultra-sonic signal when air from the tyre passes therethrough When the air pressure is between upper and lower values it acts against bias of spring 46 to prevent the piston moving to a position in which air from the tyre and below the piston can pass via a recess 48 or 50 and bores 42, 38 to the ports 40. When the air pressure exceeds the upper value air passes the piston via recess 48 and when the air pressure is below the lower value air passes via recess 50. The stem may additionally have two coloured bands thereon both or neither being shown being indicative of an air pressure not between the upper and lower values. Projection 60 maintains the tyre valve open. In a modified device (Fig. 3) the tyre valve 98 is mounted in a bore 84 provided in the stem and upon inflation of the tyre the piston is moved by gas pressure to the lower end of the housing so that the gas can pass into the tyre via grooves 100, 102. In a further modification the piston is movable within a sleeve (116) (Fig. 4, not shown) which is mounted on an expansion member (126) or the spring (122) is mounted at one end on an expansion member and in either case the device compensates automatically for differences in ambient temperature.

Title: Yarn piecing apparatus data communicating means and method
Inventor: LEE C
IPC: D01H15/013
Filed: 1971-08-09
Abstract: 1353552 Piecing arrangements; signalling PARKES-CRAMER CO 9 Aug 1971 [10 Aug 1970] 37344/71 Headings DID and D1F [Also in Division G4] An operation of a tending apparatus movable along a textile yarn forming apparatus is monitored to produce and communicate a signal indicative of states of the monitored operation, such signals being processed to permit determination therefrom of cause of failure of the monitored operation. A yarn piecing apparatus is movable along a textile yarn forming machine for locating ends-down and piecing up such ends-down. For piecing up, yarn from a supply package is threaded through a tensioning guide to pass generally-horizontally to a lower distending gripper, the yarn contacting a feeler actuating a first switch to indicate presence of the yarn on the way. An upper yarn gripper is moved down and then up to engage a free end of the yarn and draw it up. If the yarn breaks, the loss of tension in the yarn permits the upper gripper to rotate, actuating a second switch. An auxiliary gripper is also provided which clamps the length of yarn adjacent the upper gripper, and lack of tension due to breakage permits this auxiliary gripper to rotate, actuating a third switch. The states of the switches are entered into a first set of flip-flops, transferred to a second set of flip-flops, then serialised for transmission as in Specification 1353551 (referred to), to a receiver to detect the cause of any failure (taking into account the steps in the sequence of operations at which signals occur), and may cause abortion of the piecing-up operation. Failure to piece up caused by failure of the spinning mechanism, e.g. absence of a traveller from a spinning ring, may also be detected and signalled. Ends-down may also be detected and signalled.

Title: Uranium recovery and purification process and production of high purity uranium tetrafluoride
Inventor: BAILES RICHARD HAZEL
IPC: C01G43/06
Filed: 1954-12-31
Abstract: Uranium values are recovered from an impure source material by leaching with hydrochloric acid and an oxidizing agent increasing the chloride ion concentration to above 5M to convert the uranium to an uranyl chloride complex anion which is then adsorbed on an anion exchange resin together with the impurities; the resin is washed with hydrochloric acid of above 5M concentration to remove impurities and leave the uranium values which are then eluted with water; they are recovered from eluate preferably by electrolytically reducing to the tetravalent state and precipitating with hydrogen fluoride as uranium tetrafluoride. The source material may be an ore such as pitchblende, phosphate rock, carnotite, or a material, mainly in the form of uranous phosphate or sodium uranyl fluoride, obtained by eluting uranium values from an ion-exchange resin with 1M Na Cl, adding HF, adjusting the pH to 2,5-3,5 and adding a reducing agent.  The preferred oxidizing agent for the leaching is sodium chlorate. Any dissolved pentavalent vanadium may be selectively reduced by adding sodium acid sulphite, sulphur dioxide or hyposulphite. Strongly basic anionic exchange resins are preferably employed, and the impurities are eluted therefrom by hydrochloric acid of concentration of above 5M after which the uranium is eluted with water and passed to the cathode compartment of an electrolytic cell having a mercury cathode. After reduction to the tetravalent state the uranium is precipitated as the tetrafluoride by treatment with hydrogen fluoride solution.

Abstract: 1311066 Processing seed for human or animal consumption C W PIERCE and J L TAYLOR [trading as CHARDO PIERCE MICRONIZING CO] 7 Aug 1970 [2 Sept 1969] 38198/70 Heading A2Q Whole seed is processed to render it more suitable for human and animal consumption by a method comprising the steps of heating the whole seed by subjecting it to infrared radiation for a period of time only sufficient to convert the seed into a soft turgid, malleable and plastic form, but avoiding drying and parching, and immediately thereafter rolling the seed while hot and in said soft turgid and malleable form, whereby the seed is converted into wafers or flakes which have a bulk increase not in excess of 50 per cent and which do not crack nor crumble. The method may be applied to grain sorghum, milo, corn, wheat, rye, barley, soy beans, navy beans, peas or pinto beans, and is stated to be particularly suitable for seed from grain sorghum or milo. When treating sorghum, heating is preferably conducted for a period of time sufficient to but less than 1 per cent of the seed pop before reaching the rolling step. In apparatus for carrying out the method, the seed passes from a supply hopper 12 having a kicker 14 to a cleaning screen 16. A blast of air may be used to assist the cleaning action. From the screen 16 the seeds pass to an inclined plate which is vibrated by a rotating crank 24 and link 23 so that the seeds move downwardly along the plate past a series of infrared heaters 26, the speed of travel of the seed being adjusted so that the seed is exposed to heat for from 20 to 30 seconds. The seed then passes to a hopper 32 at the outlet of which is positioned a pair of driven flaking rollers 34, 35 one of which is adjustable towards and away from the other. The rollers have helical grooves to mark a pattern on the resulting flakes or wafers. The flakes or wafers produced are arranged to be of thickness not greater than 0.05 inch. Each wafer is arranged to have a density of about 35-37 pounds per bushel, and a moisture content of about 8 per cent. A compacting cylinder having an auger may compact the flakes or wafers so produced.
