Title: Automatic and combined containment and flow diversion system
Inventor: BACK BRIAN MORRIE
IPC: F16K7/10
Filed: 2009-10-16
Abstract: A system that can be installed via the inspection chamber of a drainage system as illustrated in Fig 1 through to Fig 7 that simultaneously deploys an inflatable bladder 6 and suction hose 4 by virtue of the pressure exerted during the inflation of the inflatable bladder alone 6 acting against the roof of the drain 2 and the hose itself. The hose which is connected to a pump 7 then operates, diverting the flow into a storage tank 8 or foul sewer, hence increasing the on site capacity to deal with spills of hazardous materials, firewater or overflows from oil interceptors. Upon deactivation the whole assembly automatically retracts under the force of gravity by virtue of the counterweight 5 acting about a fixed pivot 14 near the top of the inspection chamber 1, thus leaving the flow unimpeded. The system also has the ability to raise an alarm upon activation or system failure using audible and visual means locally or remotely using any available form of telemetry or signalling via the controller 10.

Title: A process for the concentration of partially polymerised esters
IPC: C08F18/08
Filed: 1948-04-15
Abstract: Polymers of a polymerizable organic ester which, when completely polymerized, gives rise to cross linkage between polymer molecules, are concentrated by contacting a partial polymer of the ester with a mixture of two liquids so as to form two phases, the proportion in which the polymer is divided between the two phases being different from the proportion in which the unpolymerized ester is divided between the two phases and separating the two phases.  The process is particularly applicable to diallyl phthalate which preferably is polymerized to an extent of from 20 to 40 per cent.  The two liquids may be acetone and water, benzene and isopropanol, acetone and isopropanol, methyl ethyl ketone and water, methyl ethyl ketone and isopropanol, or toluene and methyl alcohol.  After separation of the two phases the lower phase, which contains most of the polymer, may be treated with a fresh quantity of a mixture of the same two liquids again to form two phases, and the phases formed then separated.

Title: Improvements in signal amplitude control systems employing semi-conductor devices
IPC: H03G1/00
Filed: 1950-04-28
Abstract: 673,258. Semi-conductor amplifiers. RADIO CORPORATION OF AMERICA. April 28, 1950 [May 28, 1949], No. 10525/50. Class 40 (iv). A variable impedance device comprises a transistor having impedance elements connected in circuit with the respective base, emitter and collector electrodes, an input signal being connected across at least a portion of one of the impedance elements, and means being provided to vary the current flowing through at least one of the electrodes to control the amplitude of the output signal from one of the electrodes. Fig. 1 shows a circuit arrangement comprising a transistor having a semi-conductor body 10 of N-type germanium, and emitter and collector electrodes 11, 12 biased positively and negatively respectively with respect to base electrode 13. Base electrode 13 is grounded through resistances 14 and 15, the input signal being applied across resistance 15. The output signal may be taken from terminals 21 between base electrode and ground, or from terminals 28 between collector and ground. It is shown that if the collector current is varied by altering the collector bias by means of tap 25, or by varying resistance 26 in the collector circuit, the impedance between the base electrode and ground is varied over a range of positive and negative values, thereby giving control of the amplification or attenuation of the signal. Alternative arrangements are described in which the input is applied across part of the impedance in the collector and emitter circuits, and the output may be taken from the collector, base or emitter electrodes. The impedance between any of these electrodes and ground may be made positive, infinite, negative or zero, and control of this impedance may be affected by varying the collector or emitter bias, or the value of the impedances in the collector, emitter or base electrode circuits. The control facilities may be applied separately or simultaneously, whereby the amplitude of the output signal is a function of four variables. The device may be used in servo systems or as part of an analogue computer. Condenser 20 in Fig. 1 is provided to assist stability. The semi-conductor body may also consist of boron, silicon, tellurium or selenium. A constant-current source may be used in place of the emitter bias sourse to maintain the emitter current constant.

Title: Improvements in indicating systems for electrical signals
IPC: H04L15/28
Filed: 1942-07-28
Abstract: 559,062. Indicating systems for interlocked dotdash electrical signals. STANDARD TELEPHONES & CABLES, Ltd., EARP, C. W., and WESTON, J. D. July 28, 1942, No. 10544. [Class 40 (v)] A system for distinguishing between complementary dot and dash signals, particularly those received from overlapping beams defining a navigational path comprises means for removing the unidirectional component from the received signal wave and for applying the resultant wave to the coil of an indicating instrument through two parallel paths, one of which produces in one direction through the coil a current dependent on the amplitude of the positive parts of the resultant wave, and the other produces a current in the reverse direction dependent on the amplitude of the negative parts of the wave. In the system shown the demodulated signals from the overlapping beams are applied to a valve V, in the anode circuit of which is a condenser C1 which removes the continuous current component, giving a wave-form as shown either to the left or to the right at a, Fig. 2, according to whether dots or dashes are being received. This wave is applied in parallel circuits to reversely-directed rectifiers W1, W2. The first passes only the positive parts of the wave, giving a voltage across R1 of one of the forms shown at b, according to whether dots or dashes are received, and the second passes only the negative parts of the wave, similarly giving a voltage across R2 of one of the forms shown at c. The voltage waves across R1 and R2 are respectively passed through networks C2, R3 and C3, R4 which remove the unidirectional components and are applied through reversely-directed rectifiers W3, W4 to a centre-zero direct-current measuring instrument A. The curves d, c show the wave forms of the voltages across R3 and R4 respectively. If dot signals are reecived, the wave-forms shown on the left at d, e will be applied respectively through the rectifiers W3 and W4 to the instrument, which will accordingly be affected by the negative parts of the d curve and the positive parts of the e curve, and since the amplitude of the d curve is greater than that of the e curve the integrated current through the instrument will be negative. Similarly, when dashes are received the amplitude of the e curve is greater, and the integrated current is positive. The condensers C2, C3 are preferably large, but small condensers may be employed which pass only pairs of oppositely-directed pulses as shown at d1, e1. The rectifiers W3, W4 may both be connected in the reverse direction to that shown. If the rectifiers W1, W2 have an appreciable backward conductance C1, R1 and R2 may be omitted.

Title: Improvements in or relating to means for injecting liquid-fuel into internal-combustion engines
IPC: F02M67/02
Filed: 1924-04-30
Abstract: 237,651. Olsen Engine Syndicate, Ltd., and Olsen, S. D. April 30, 1924. Cylinders receiving liquid fuel.-Liquid fuel, mixed with air abstracted during the compression stroke from the cylinder, is injected into the combustion chamber by a spring-actuated plunger c, Fig. 1, which is retracted by a cam and which surround a valve member d actuated by a separate cam. Fuel is supplied to the space below the piston d through a passage k while the valve d is closed, and on the opening of the valve the fuel is mixed with air entering from the working cylinder through a tangentially disposed orifice i. The valve d is never lifted sufficiently to remove the lower end of the stem from a cylindrical orifice h. At the commencement of injection the valve d closes slightly. in order to bring an atomizing device f carried by the valve into position in the passage h<1>, so that the fuel and air entering the combustion chamber are compelled to pass through a restricted passage surrounding the atomizer f, the conical upper surface of which scatters the charge in the combustion chamber. In an alternative construction, shown in Fig. 8, fuel is supplied to the upper face of the piston c, and is delivered to the lower end of the injector cylinder on the raising of the piston c through a by-pass i. The valve member e<1> and atomizing device f<1> are carried by the piston c, which is an easy fit in its cylinder, and is provided with a spring-pressed member l which tightly seals the fuel inlet orifice k<1> when the piston is raised. The upper end of the piston may be inclined so that by turning it the degree of clearance at the orifice k<1> may be exactly adjusted. A needle valve may be provided into the oil supply pipe k, the fuel being sucked into the space above the piston c on the downstroke of the piston. According to one of the Provisional Specifications, the atomizer may consist of two annular projections on a stem such as f<1>. These projections fit in the fuel injection passage and are provided with staggered longitudinal grooves through which the charge passes to the combustion chamber; below them a conical member such as f may be provided. A passage such as i, Fig. 1, may open into the seating of the valve d.
