Title: Improved means for the emission of an audible warning if a puncture occurs in a tyre of a motor road vehicle
IPC: B60C23/04
Filed: 1930-02-11
Abstract: 337,185. Baxter, A. E. Feb. 11, 1930. Puncture or deflation, indicating.-In an apparatus for the actuation of a warning or signalling device to indicate that the air pressure of a pneumatic tyre has fallen below a predetermined value, a tube e of extensible material is connected at one end to part of a tyre valve and at the other end to a displaceable member normally held in a stationary or inoperative position by the pressure of air in the tyre. The part c of the tyre valve is connected with the wheel tyre by a tube a. The displaceable member f normally contacts with the control member g of an ordinary clockwork-bell mechanism comprising a ratchet wheel j cooperating with a striker member l. On deflation, the elasticity of the tube e or, the pressure of a spring, releases the member g and causes the bell to ring.

Title: Process for the preparation of therapeutic magnesium aluminate hydrate
IPC: A61K33/08
Filed: 1956-07-18
Abstract: A magnesium aluminate hydrate, probably having the formula <FORM:0810816/III/1> is prepared by reaction of an alkali metal aluminate solution and a magnesium salt solution at not above 50 DEG C.  The aluminate solution contains 3-5 mols. of alkali metal oxide per mol. of Al2O3, and the quantities of reactants are such that the atomic ratio Al/Mg=0.9-3, preferably 2.  The product is separated as a precipitate, washed until it contains not more than 0.5 per cent of water-soluble salts and left undried or dried at not above 120 DEG C.  The magnesium salt may be the sulphate, chloride, bromide, iodide, nitrate or acetate, Examples of some of these being given. The alkali metal aluminate may be prepared by reacting an aluminium salt (such as a sulphate, chloride, bromide or nitrate, all of which are exemplified) and an alkali metal (e.g. sodium) hydroxide in solution, 6-8 mols. of the latter being employed for every gram atom of aluminium.  It is preferred to add the alkali metal aluminate to the rapidly stirred magnesium salt solution in the form of one or more thin jets to facilitate even distribution; alternatively, both solutions may be introduced in the form of jets into stirred water or previously prepared magnesium aluminate hydrate.  After filtering or centrifuging the solid, which in Example 1 is colloidal and washing, e.g. by decantation, the product may be dried, generally at below 70 DEG  C., under vacuum if desired.  Using short-drying times, a temperature of e.g. 110 DEG  C. may be used (roller drying and spray drying with a 6-15 per cent by weight aqueous suspension at 60-100 DEG  C. are mentioned).  Thereafter, if necessary the product is comminuted in a ball or vibratory mill, e.g. to 0.10-0.12 mm. particle size. The product (which may be used as an antacid, see Group VI) has strong buffering properties for acids, in the pH range of 3-5, details being given in respect of hydrochloric acid.  The pH value of a suspension in water is 9-11.

[Also in Division F2] Air under pressure is admitted to organ pipe 24 from a box exterior to moulded plastics housing 10 when internal and external pallets 13 and 14 are moved away from circular holes 11, 12 in the housingwallsbyhingedarmature 18, as electromagnet 19 is actuated, permitting a flow of air through holes 11 and 12. The pallets are rigidly attached to rod 15 and are laterally located by a register 26. Only a small force is required to move the pallets away from the holes, as air pressure forcing pallet 12 against the housing wall is balanced by air pressure forcing pallet 11 away from the housing on its side. When the electromagnet ceases to attract armature 18, spring 17 returns the pallets to their original positions, so that they cover holes 11 and 12 again and cut off the flow of air. Conveniently pallet 14 and hole 12 may be made slightly smaller in area than pallet 13 and hole 11, so that in the closed position a slight net force exerted by air pressure towards opening of the holes remains to be overcome by spring 17.

Title: Improvements in or relating to frequency modulation receivers
IPC: H03G3/34
Filed: 1961-06-22
Abstract: 945,861. Muting circuits. WESTERN ELECTRIC CO. Inc. June 22, 1961 [June 29, 1960], No. 22633/61. Heading H3Q. In a muting circuit for a frequency modulation receiver, in which a muting voltage is developed from the noise present in a noise channel, the band width of the noise channel is varied in accordance with the signal level. In this way operation of the muting system by the higher frequency components of speech modulation of a desired signal is prevented. Audio signals from the discriminator 30 are fed to audio amplifier 40 and thence to reproducer 45. They are also fed to branch amplifier 52 and thence over filter 60 to noise rectifier 53, the output of which is amplified in D.C. amplifier 54 and supplied as a muting voltage to the amplifier 40 in the signal channel. The filter 60 which selects noise components from the output of amplifier 52 for operation of the muting system is of variable bandwidth, comprising series capacitors 61, 62 and a pair of series-connected shunt resistors 63, 64. The resistor 64 is shunted by the contacts of a relay 55 which is operated from the output of D.C. amplifier 54. In the absence of a signal the noise is high and produces a sufficient output at D.C. amplifier 54 to mute the receiver and also to energize relay 55, maintaining its contacts open so that the bandwidth of filter 60 is wide. Upon reception of a signal, the reduction of noise gives an output from D.C. amplifier 54 which is insufficient to mute the receiver and which is also insufficient to energize relay 55, thereby closing the contacts and reducing the bandwidth of filter 60. The muting is then less liable to be operated by higher frequency components of speech modulation. The second contact of relay 55 may also be utilized, to earth the grid of a valve in the amplifier 40 in the muting condition.
