Abstract: 1526957 Respiratory apparatus R L HESSE 19 Sept 1975 [20 Sept 1974] 38634/75 Heading A5T [Also in Divisions B1 and G3]  A gas supply device for controlling the discharge to a patient of one another or a mixture of two or more gases, one from a non-pressurised source, comprises a selfexpanding lung ventilating bladder 9, Fig. 5, with an outlet 10 to the patient and an inlet having a check valve, 6, 7, permitting gas flow only into the bladder, an inlet valve connected to the bladder inlet via a central outlet opening 4 of a housing 1 enclosing a cylindrical vortex chamber 1' having at least one suctional intake opening 2 in communication with said non-pressurised source, and at least one nozzle 3 for connection to a pressurised gas source which discharges substantially tangentially into the inlet valve such that a pressurised gas supply controls the intake through the opening 2 by arranging the pressure drop between opening 2 and the outlet opening 4. The suctional intake opening 2 may be a slot extending along an arc of a circle. Arrow 8 indiciates the vortex flow of pressurised gas from nozzle 3 during bladder expansion and arrow 12 the flow, Fig. 4, of non-pressurised gas from intake opening 2 when no gas flows from nozzle 3. Fig. 5 shows the two gas flows together, the now spiral flow 12 causing a pressure difference between the intake 2 and the outlet 4 and as more gas flows from nozzle 3, less flows from opening 2, until only pressurised gas flows. In the expanded condition of rest of the bladder, some gas from nozzle 3 flows into the bladder and some flows out through the intake opening 2, Figs. 9, 10 (not shown). The embodiment of Fig. 11 (not shown) includes a gascollecting chamber 15 for recovery of gas exiting through opening 2. The check valve may be situated either on the bladder inlet, Fig. 12, (not shown) or the inlet valve outlet. The embodiment of Fig. 13, (not shown) has two substantially tangential nozzles (3') for different gases and intake openings (2').

Abstract: 342,463. Boiler furnaces. KATZ, H., 91, Vogelsangerstrasse, Ehrenfeld, Cologne Germany. Dec. 17, 1929, No. 38652. Con vention date, Dec. 17, 1928. [Class 51 (i).] In a boiler furnace of the type provided with grids arranged in the exhaust flue and means for blowing supplementary air or steam into the waste gases, blast pipes h with nozzles k are arranged behind the grids c and d which are located above or directly behind the fire bridge, so that highly heated supplementary air can be blown into the waste gases in the form of a counter current. The supplementary air is heated by a preheater v. Above the grids is a funnel e connected with the suction side of a blower f and adapted, when the development of smoke is very great, to draw off the smoke to be mixed with the supplementary air which is supplied through a pipe g. In order that the heated mixture of supplementary air and exhaust issuing from the nozzles k may have a high velocity, it is led to the nozzles through counter current passages h and at the point where the direction changes an additional high velocity current of steam or the like is introduced by inlets i, and has an injector action on the main current.

Title: Method and apparatus for condensing aluminium in gaseous distillation process
IPC: C22B21/00
Filed: 1960-11-10
Abstract: <PICT:0947227/C3/1> Thermally unstable gaseous compounds of aluminium, such as sub-halides, are decomposed by passage along a path defined by surfaces of graphite having an apparent specific gravity of greater than 1.5, the graphite being cooled at such a rate as to maintain its surface temperature between about 1200  DEG C. and 660  DEG C.  Cooling may be effected by allowing heat to radiate from the graphite to a surrounding thermally conductive body spaced therefrom, said body being cooled if necessary by liquid coolant. Excessive cooling at the outlet end of the condenser may be avoided by interposing thermal shielding between the graphite and the outer body.  In the form illustrated, the graphite forms a column of trays 44 and 45, each having a perforated bottom plate, the holes in alternate plates being offset, and the column is closed by cover 49, and by well 50.  The entire graphite assembly is enclosed in steel shell 52, which may be cooled by coil 53.

As shown, the filter is movable between two positions and in the monitoring position a switch 48 actuated by a filter support arm 16 closes a circuit such that any signal received on the cell 44 may be amplified at 60 and applied to the base of a switching transistor 66; a signal of positive polarity, opposite to that of a reference potential in the circuit allows the transistor to conduct energize a relay 68 which actuates switch 70 of an alarm bell or a flashing light circuit 76. The filter, which may be dichroic, is movable by solenoids 22, 24 actuated by switch 26 forming part of a circuit responsive to the amount of primary colour in the printing beam. A switch 48 prevents the photo-cell from being energized when the filter is in the printing position. The monitoring light beam is provided by a lamp 30 and a directional filter 42 is present in the beam 36 for passing only perpendicularly incident light. The term 'light" includes infrared, ultraviolet and X-rays.

Title: Synchronizing circuits

Filed: 1974-09-09
Abstract: 1480355 Transistor bi-stable circuits INTERNATIONAL STANDARD ELECTRIC CORP 9 Sept 1974 [28 Sept 1973] 39208/74 Heading H3T An arrangement for synchronizing a data signal R with a clock signal S comprises: a first bi-stable B fed with the clock signal and the data signal; a second bi-stable A fed with the clock signal and a delayed version of the data signal, the delay, unit 2, being greater than the time taken by the bi-stable to settle down into a stable state when triggered; a variable delay circuit Tc supplying, in response to the clock signal S and the output of one of the bi-stables A, a signal delayed with respect to the clock signal by time dependent according to the relative phase conditions of the clock and data signals; and a coincidence circuit, e.g. an AND gate 3, providing an output representative of the state of the output of the other bi-stable B, in response to the output from the delay circuit Te. Between the time at which a bi-stable is triggered and the time at which it responds by assuming a stable output state, an "unstable state" occurs. Due to the input delay circuit 2, if bi-stable B is in the unstable condition then bi-stable A has a stable "0" at its QA output, and if bi-stable A is in the unstable condition, then bi-stable B has a stable "1" at its QB output. If the R and S inputs are such that bi-stable B is "unstable" and bi-stable A has output QA=0, then the "1" level of the signal S charges capacitor C through resistor 4 until it reaches the threshold of comparator 6 which then produces a "1" level at its output to open output to open gate 3. The delay produced in Te is sufficient to allow bi-stable B to produce a stable "1" at its QB output, which is then passed to output F. If the circuit is such that both bistables have stable "1" outputs, capacitor C receives charge from QA via resistor 5 as well as the charge from S via resistor 4, thus reducing the delay time. If the output QA is in its "unstable" state, then the charge via resistor 4 will be augmented by some charge from the QA output, and the delay produced by Te will lie between that produced when QA= "0" and that produced when QA="1". With the above described arrangement, synchronization takes place on the leading edges of the data signals. In a modification Fig. 3A (not shown) synchronization may be made at either leading or trailing edges. In this arrangement, the data signal and delay data signals are fed to an AND gate and an OR gate whose outputs are fed to the two bi-stables respectively. In a second modification Fig. 4 (not shown) the output AND gate 3 is replaced by a third bi-stable (19) and reset circircuits are provided for the bi-stables.
