Title: Improvements in diaphragm sounders
IPC: G10K9/04
Filed: 1924-11-29
Abstract: 225,569. Krupp Germaniawerft Akt.- Ges., F. Dec. 1, 1923, [Convention date]. Horns, construction of.-In a horn of the type in which sounds are produced in a fluid stream by a diaphragm B covering the end of a supply pipe D, and in which the temperatune of the operating fluid, for example, steam or carbonic acid, is considerably above or below the temperature of the atmosphere, the temperature of the diaphragm is permanently kept in the neighbourhood of the temperature of the fluid either by the fluid itself or by a separate heating device such as an electric heater. For example, in the steamoperated horn shown, the diaphragm is heated by the permanent passage of the steam through a chamber E. In order to prevent the diaphragm from changing its temperature owing to contact with the outer air in the casing A, it is formed with an insulating layer; for example, in the diaphragm shown in Fig. 3, a layer of air is enclosed within a flat annular groove in the outer layer N. In an alternative construction of diaphragm, two metal layers are covered with a third layer of asbestos, which is fixed by an outer thin brass plate bent over the edge of all the layers.

The system of the main patent (Specification 1,129,502), in which binary data representative of Alpha-Numeric information in binary coded form is converted into video signals and supplied under the control of a clock to the video signal circuits of a cathode-ray picture tube at a speed corresponding to the video signal utilization rate of the tube and in synchronism with sweep control signals from the clock is modified by the provision, inter-alia, of a cyclic distributor operating on a time multiplex basis to distribute to respective ones of a plurality of cathode-ray picture tubes video signals derived from sequences of binary coded signals from a plurality of sources. As shown in Fig. 1, the sources comprise keyboards 20, each associated with a respective cathode-ray picture tube 22b, 22c constituting line display terminals of which a larger number, e.g. thirty-two may be employed in practice. The keyboard of a supervisor display terminal 22a also provides binary coded signals and provision is made to receive data from and to communicate with a remote data processor 19 via telephone data sets 17 and 18. The signals produced by the keyboards 20 are supplied via a selector 28 and multiplexer 69 to a memory store 33 in which they are stored in different assigned portions under the control of timing signals from a clock 44. Also, under the control of the latter, the stored binary coded signals are cyclically supplied to a character generator 34 which produces the actual video signals required to produce the displays and such signals are cyclically distributed to the various display terminals on a time multiplex basis via a distributor 35 controlled by the clock. The character generator and the display production operation is similar to that described in the main patent. The information displayed on units 22b and/or 22c may be displayed on the supervisor unit 22a separately or in combination with further information from a television camera 25 and a tape recorder 26 and the keyboard of the supervisor unit may be utilized to modify the information from the other keyboards which is stored in the memory. The assigned portions of the memory comprise four separate main memory units (Fig. 2, not shown) and to increase the capabilities of the system the amount of stored information to be displayed on each display unit may be reduced by up to a factor of eight so that each main memory unit serves eight display units making a total of thirty-two units. Details of the various elements of the Display controller 21 are described with reference to block circuit diagrams (Figs. 2 to 5, none shown).

Title: Separating Condensable Vapours from Gas Mixtures
Inventor: SPENCER JOHN RAYMOND
IPC: C10G5/02
Filed: 1968-06-18
Abstract: 1,187,938. Separating hydrocarbon gases. CONTINENTAL OIL CO. 18 June, 1968 [10 Aug., 1967], No. 29058/68. Heading B1L. Condensables are removed from a hydrocarbon feed gas, e.g. natural gas, by sorption, the sorbent e.g. activated carbon, being subsequently desorbed and regenerated by means of a heated gas stream, a surge zone being provided which communicates both with the feed line and with the regeneration circuit. As shown, in a 3-phase cyclic process, feed gas is passed by lines 1 and 2B to sorbent bed in adsorber 6, effluent depleted of condensables and other constituents leaving by lines 7B and. 3. Meanwhile, adsorber 5 is being desorbed and regenerated by a heated gas stream which arrives by lines 8, 9A and 2A, the rich effluent which leaves by lines 10A, 11, 12 and 13 passing through coolers 14 and 15 to scrubber 16, the condensables condensed therein being withdrawn as product by line 17. The effluent gas therefrom passes by line 18, booster 19, line 20, heat exchanger 21 and line 22 to heater 23 before recirculation by line 8. Surge tank 24, filled with glass fibre or containing baffles, is connected to scrubber 16 by line 25 and to feed line 1 by line 26. At the same time as adsorber 5 is being desorbed, adsorber 4 is being cooled prior to coming on stream by means of a cool residue gas stream fed by lines 27, 30 and 2. The effluent heated gas then passes by lines 29 and 28 to heat exchanger 21 to heat gas in the regenerating phase leaving scrubber 16 and then passes by line 31 and either out of the system through lines 32 and 3, or is recirculated by lines 33, booster 34 and cooler 36, or both. At the end of the regeneration phase, coolers 14 and 15 and scrubber 16 are bypassed by opening valve 21 and closing valve 22 so as to displace hot gas from adsorber 5 to adsorber 6 until the displacing gas just reaches the outlet of adsorber 6; at this point, valve 21 is closed and valve 22 reopened, and the adsorbers switched so that adsorbers 6, 5 and 4 are operated in the regeneration, cooling and sorption phases respectively. If preferred, the displacement gas may be drawn from lines 27, 30A and 2A into adsorber 5, in which case coolers 14 and 15 and scrubber 16 are not by passed. The flow rates of feed and of the circulating gas stream in the regeneration circuit is controlled automatically at the points indicated by controller R.F.R.C. The inclusion of surge tank 24 provides a volume into which the gas in the regeneration circuit can expand when pressure therein rises quickly at the start of this phase because of the initial preferential desorption of non-condensables and this expansion may pass gas through the tank and back into the feed line, later in the phase, as condensables are desorbed and condensed, pressure drops and the gases which have expanded into the tank pass back into the regeneration circuit.

Title: Process and apparatus for increasing the viscosity and water-solubility of plastic materials
IPC: C11D13/00
Filed: 1950-11-28
Abstract: <PICT:0727646/III/1> <PICT:0727646/III/2> The viscosity and water-solubility of plastic materials containing a crystalline phase (e.g. soaps and synthetic detergents such as sulphated monoglycerides) is increased by forcing the solid plastic material through a shearing and compacting zone comprising a pair of walls substantially uniformly spaced apart a distance of the order of not more than one sixty-fourth of an inch, the shearing and compacting being caused by relative movement of the walls in a direction substantially parallel to their length.  The pressure applied to the plastic material entering the shearing and compacting zone is sufficient to ensure that the material completely fills the zone, while the temperature of the material passing through the zone is maintained below its melting point.  In Figs. 1 and 3, a metal band 3 is mounted on driven wheels 1 and 2 and passes through metal die slot members 7 and 8.  Plastic material enters die slot members 7 and 8 through plodder-type feeding devices 6 and leaves via hoppers 13 and 14.  Die slot members 7 and 8 are provided with a slot 21 through which the band 3 passes, the clearance between the band and the walls of the slot being not more than about one sixty-fourth of an inch across the breadth of the band.  Slot 21 is provided with a labyrinth seal 23 at its entrance, in order to prevent escape of plastic material which is introduced into p  chamber 20.  Plastic material adhering to band 3 as it leaves slot 21 is removed by knives 35 in the form of flakes or chips.  Slot 21 may be provided with expansion chambers 29, and also stripper chambers 30 wherein the plastic material is stripped from band 3 by means of knives 31 and then allowed to recoat the band again. Gases such as air may be introduced into stripper chambers 30 through line 15, for example in the production of aerated soap or synthetic detergent, particularly floating soap.  Alternatively, line 15 may be connected to a source of vacuum in order to remove gases from the plastic material.  The die slot members 7 and 8 may incorporate cooling chambers and band 3 may also be cooled.  Soap flakes or chips obtained by the process may be compacted into tablets, or used to prepare shaving creams or powders.
