Title: System and method for pausing an ongoing transmission in a communication system
Inventor: WIATROWSKI DAVID G
IPC: H04W72/12
Filed: 2008-05-07
Abstract: A system and method for pausing communications from a transmitting radio for a certain period of time in order to allow transmission of other messages. When a first radio determines that a message needs to be transmitted either to a second radio or the transmitting radio, the first radio determines whether there are any available forward channels to transmit the call. If no forward channel is available, the first radio determines a period of time required to transmit the message and sends, on a reverse channel, a "request to pause" signal to the transmitting radio identifying that period of time. Upon receiving the "request to pause" signal, the transmitting radio ceases transmission on the forward channel for the specified period of time, during which time the first radio transmits the message.

Title: Improvements relating to hydrogen-ion-exchange processes for the treatment of water
Inventor: BLIGHT FRANK CHARLES
IPC: B01J39/04
Filed: 1952-04-23
Abstract: 724,003. Purifying water. PERMUTIT CO., Ltd. April 9, 1953. [April 23, 1952 ; April 8, 1953] Nos. 10244/52 and 9556/53. Class 46. Water is treated by passage through two beds of hydrogen-ion-exchange materials, one bed containing strong groups and few or weak groups, and the other weak groups and few or no strong groups, the water under treatment flowing first through the bed containing the weak groups and then through the bed containing the strong groups, and the beds are regenerated by an amount of acid in excess of that required for regeneration of the strong groups, all the regenerating acid flowing through the bed containing the strong groups and either all or all but an initial fraction of the effluent acid from this bed flowing through the bed containing the weak groups. The exchange materials are preferably synthetic resins, that containing the weak groups having a smaller specific gravity than, or smaller. particle size than, that containing the strong groups, a bed of the former resting upon a bed of the latter. Water to be treated is passed downwards through the beds in succession. After backwashing prior to regeneration the beds re-settle as before. Regenerating acid is then passed upwards through the beds in succession, excess from the strong group bed regenerating the weak group bed. Remaining acid is washed from the strong to the weak bed by upflowing wash water where it effects further regeneration. Ordinary water, used for washing, leaves metallic cations in the bottom part of the strong bed which would in turn be taken up by downflowing water in the subsequent service run, such water having become acidic by contact with the preceding part of the beds. This may be avoided by putting the beds in separate containers. Fig. 4, and passing regenerant downwards, first through the lower bed and then the upper ; the washing water follows the same path. The beds may be in one container with an additional distributing device A, Fig. 5. Regenerant from the bed S alone is collected in a tank T, Fig. 5, thence pumped to the top of the bed W, Fig. 6, from which it is removed by the device A, now (after appropriate alteration of valves) acting as a collecting device. Where the water contains much calcium permanent hardness, and sulphuric acid is the the regenerant, the deposition of calcium sulphate in the bed W may be avoided by passing to waste at P, Figs. 4 to 6, that portion of effluent regenerant from the bed S having a high calcium content. Specification 684,848 is referred to.

Abstract: 800,521. Removing moulds from cast concrete articles. TRIP'S BETONMAATSCHAPPIJ N.V., E. H. April 4, 1956 [April 20, 1955], No. 10336/56. Class 87(2). Apparatus for use after moulding objects of concrete with straight sides comprises a rope 18 passed over a guiding member 15 and serving to hoist the mould from the object and members 14 for holding down the object, the holding and guiding members being suspended from a common part above the mould and associated with means for counterbalancing the weight of the mould and holding members. Fig. 1 shows the apparatus applied to a mould for casting concrete pipes of square section, but it is applicable to moulds for all sections whose walls are straight and parallel. A beam 10 is pivoted to the top of a standard 9 and carries at one end, forming the above common part, a cross piece 13 and at the other end a counterweight 12. A plate 22, apertured to fit between the inner and outer mould walls 16, 17, Fig. 3, is placed on the surface of the concrete in the mould and on the upper side of the plate, the feet 14a of the holding-down members 14 rest, the uprights of which extend to the cross piece 13, on which they are pivoted. The tops of the mould walls are flanged and under the flanges fit hooks in a member 21 which hangs from the rope 18. The rope is guided round a pulley 11 to a drum 19 mounted on the standard 9. The mould is stripped from the casting by winding the rope 18 on the drum, the holding-down members 14 preventing the casting from being carried up with the mould. The lengths of the hooks from the members 21 can be arranged so that the inner mould part is raised shortly before the outer and vice-versa. By moving the counterweight, adjustment may be made for the pressure exerted by the holding down members to equal the frictional force between the casting and the mould. For casting a rectangular container a mould as shown in Fig. 7 may be used, which is inverted in order to apply the stripping apparatus. To facilitate the inversion semi-circular hoops 25 may be fitted to one side of the mould.

Abstract: 632,286. Audible and like signalling apparatus. SUBMARINE SIGNAL CO. June 29, 1943, No. 10567. Convention date, Aug. 2, 1939. [Class 118 (ii)] [Also in Group XXXIX] Apparatus for transmitting or receiving compressional waves by means of a circular radiating surface having linear dimensions large compared with the wave-length is designed so that the vibrational amplitude of the elemental parts of the surface is uniform along each line 5 parallel to a given diameter but decreases progressively across the surface from the diameter to the circumference in such a way as to produce a radiation pattern in polar co-ordinates substantially limited to a plane perpendicular to the parallel lines 5 and having in that plane a main central lobe and considerably reduced subsidiary lobes on each side. The Specification contains a mathematical formula connecting amplitude and distance from the main diameter and a graphical method for determining the desired amplitude distribution. In the construction shown, a large number of magneto-strictive oscillators 3 are fixed in parallel rows to the radiating surface and the number of ampere turns in the exciting coils is the same for each row but differs in different rows. Specifications 632,284 and 632,285 are referred to. The Specification as open to inspection under Sect. 91 states also that the same effect may be produced by the use of a radiating or receiving surface vibrating with uniform amplitude but shaped so as to taper in a direction perpendicular to the central elemental row, e.g. a diamond or square. This subject-matter does not appear in the Specification as accepted.
