Title: Improvements in or relating to fluid heaters
IPC: F23N1/08
Filed: 1933-06-22
Abstract: 403,312. Fluid actuated valves. DEHN, F. B., 103, Kingsway, London.- (Askania Werke Akt.-Ges. vorm. Centralwerkstatt Dessau und C. Bamberg-Friedenau; 87, Kaiserallee, Friedenau, Berlin.) June 22, 1933, No. 17832. [Class 135.] A fluid heater is provided with means whereby the supply of fluid is controlled by the temperature of fluid entering the heater so that a constant heat supply is required to maintain a constant outlet temperature. In the form shown in the Figure a diaphragm actuated pressure regulator 9 maintains a constant difference of pressure across an adjustable constriction 3. This constriction is adjusted by a thermal element 2 arranged in the inlet conduit and coupled to a valve 3<1>. The coupling may be arranged to compensate for the varying efficiency of the heater when dealing with varying quantities of liquid. The supply of fuel is regulated by a heat sensitive device in the outlet conduit which may directly control the supply or it may adjust a quantity or pressure regulator in the supply conduit. As shown in the Figure the thermal element 13 acts through a bellows 14 and lever to varying the tension of the loading spring 15 of a diaphragm actuated pressure regulator 18. In a modification the two valves 9 and 18 are arranged co-axially and the actuating diaphragm of the valve 9 is coupled with a second valve arranged in the gas conduit and adapted to function as a water deficiency cutoff valve.

Title: Improvements in electrical signal or speech transmission systems
IPC: H04B3/06
Filed: 1929-06-11
Abstract: 334,899. Electrical Research Products, Inc., (Assignees of Mitchell, D.). Dec. 29, 1928, [Convention date]. Two-way repeating systems. -The volume or power level in a signal transmitting system is controlled by a valve having its anode circuit in parallel to the signal circuit and its grid potential controlled in accordance with the signal intensity. The control is particularly adapted for two-way signalling systems in which loss devices are provided in each channel and are oppositely controlled. The Figure shows a system in which the output energy level controls the grid bias of valves VI, V2 across the circuit L1, L2, and also oppositely controls the grid bias of valves VI, V2 in the circuit L1, L2. Echo suppressing relays are provided, the relay 21 normally short-circuiting the line. Incoming signals from L<1>1, through amplifying detector AD2 close relay 22 to render the line L1 inoperative while signals from L2 through amplifying detector AD1 open relay 21 and close relay 23. Delay circuits DC1, DC2 allowing the relays to operate before the signal arrives. Repeating coils RC1, RC2 give a high step up and a high step down respectively to the circuit so that between these coils the circuit is of high impedance. The grid bias of valves V1, V2, V<1>1, V'2 is determined by the charge on condenser C1. This condenser may be charged by either valve V3 or V4 but these valves are normally negatively biassed. The control is effected by the amplification of part of the signal current by valve V7 which reduces the current in the plate circuit of detector V6 and renders the valve V5 effective. If the power level at the output is correct the removal of the voltage drop across resistance R is counterbalanced by impulses received through the repeating coil RC3. If the power level is too low the plate current of valve V5 is decreased and resistance R1, adjusts the grid voltage of valve V3 so that condenser C1 is charged so as to increase the negative bias applied to valves VI, V2. Excess of power on the line L2 through repeating coil RC4 renders the valve V4 conductive to oppositely charge condenser C1.

[Also in Group XL (c)] Apparatus for visually comparing the gains of plural electric amplifying devices comprises a signal source, a switching means for successively and automatically applying the signal to the amplifier inputs, a goniometer whose exciting coils are respectively connected to each of the amplifier outputs, and a search coil rotatable in the combined field of the exciting coils whose voltage output energizes the deflecting element of a cathode-ray oscillograph, which element is rotated about the oscillograph axis in synchronism with the goniometer search coil, so that the size of each separate C.R. display represents the output of a particular amplifier. Fig. 1 shows part of a known Adcock directionfinding system wherein the inputs from the antennae 1, 11 are connected to the grids of triode amplifiers 2, 22 whose anodes are transformer coupled to the quadrature spaced stator coils 41, 42 of a goniometer 4 having a rotary search coil 43 energizing through amplifierdetector 5 the rotary deflection coils 7 of a cathode-ray oscillograph 6, which are driven by motor 8 in synchronism with the goniometer rotor. According to the invention the two input channels of the system are balanced by the provision of a polarized switching relay 18 operated at a frequency equal to or less than the rotational frequency to alternatively apply a suitable carrier voltage from generator 13 to the grids of triodes 2, 22 whereby two figure of 8 traces at right angles (Fig. 2, not shown) are displayed in known manner on the C.R. oscillograph, and are adjustable for equality by voltage regulating potentiometers 10 in the anode supply circuits of the triodes. The excitation outputs may be switched alternatively to a single goniometer stator winding, while multiple outputs may be switchably and sequentially connected thereto. The apparatus is applicable to comparison of the gains of more than two amplifiers by using a goniometer having a corresponding number of switchable excitation coils.

[Also in Division B5] A thermoplastic net infusion bag, e.g. for tea, is made by folding a single sheet in half, heat sealing the two parallel open sides, introducing the tea, and sealing the open mouth of the bag, e.g. by high-frequency impulse sealing. Alternatively, a length of thermoplastic net may be folded along its longitudinal axis, and transverse seals formed to produce a number of joined open-mouthed bags. Preferably, no two bags have a common heat-sealed join. After filling, and heat sealing the bag mouths, the bags may be separated. Portions of tea may be placed in the net before forming the transverse seals. The bags may be left joined and packaged in a waterproof container. The net is produced by the biaxial stressing of a sheet of a thermoplastic material, e.g. high density polyethylene, having a regular pattern of embossments or depressions on at least one surface.

Title: An improved process for the cracking of hydrocarbon oils
IPC: C10G9/00
Filed: 1944-09-22
Abstract: <PICT:0593418/III/1> A continuous process for cracking hydrocarbon oils in which a mass of powdered or granular, fluidized, non-catalytic material such as pumice or sand is maintained above 1200 DEG F. in a reaction zone into which the oil is injected in at least partly liquid condition.  Contaminated non-catalytic material is continuously withdrawn from the reaction zone and conveyed to a combustion zone where the contaminants are burned off; the purified material is then returned, substantially uncooled, to the reaction zone. The products obtained are high in aromatics; large quantities of olefins are also produced.  Cold gas oil (boiling range 400 DEG -800 DEG F.) and steam are introduced, through lines 12 and 10 respectively, into refractory-lined reactor 1 in which is maintained fluidized non-catalytic material in the form of particles of about 1/8 inch average size at a temperature greater than 1200 DEG F.  The reaction product vapours are quickly cooled to 700 DEG  to 1100 DEG F by the injection of water or steam through line 14, withdrawn from the reactor through line 15, further cooled in waste heat boiler 16 and fractionated into normally gaseous hydrocarbons, gasoline, light gas oil and bottoms in fractionator 20.  The bottoms fraction is recycled to feed line 12 via line 28 but a portion may be continuously withdrawn from the system through line 30.  The solid particles in reactor 1 accumulate coke and are continuously withdrawn through pipe 6, mixed with air from pipe 11 in mixer 9, and conveyed pneumatically via line 32 into combustion zone 33 where the coke is burned off. The purified particles are freed from combustion gases in separators 42 and returned to reactor 1.  If the heat generated by the combustion of the coke is insufficient to maintain the process, extraneous oil or other combustible material may be introduced into combustion zone 33 via line 34.  Specification 542,989 is referred to.
