Patent GB-1311712-A (GB)
Title: Carburettors for internal combustion engines
IPC: F02M7/08
Filed: 1970-06-23
Abstract: 1311712 Spray carburetters SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 23 June 1970 [21 July 1969] 30367/70 Heading F1B In a carburetter having main and slow speed supply sytems, a starting choke valve 8, for increasing fuel flow during starting and cold running of the engine, and an accelerator pump 2 which via linkage 14, 22, 19 is caused to effect a pumping stroke on opening of the throttle valve 3, the delivery capacity of the pump is increased when the choke valve is utilized so that increased acceleration fuel is delivered when the engine is cold. Closure of choke valve 8 by rod 27 angularly adjusts an eccentric shaft member 20, 24 and thereby moves the pivotal axis C of lever 19 away from the axis of actuating pin 18 of pump diaphragm 15. Thus the effective stroke of the pump diaphragm and thereby the quantity of fuel delivered during engine acceleration, is increased. Cam 11 and lever 12 cause the throttle valve to open slightly when the choke valve is closed. The choke valve may have an eccentric axle so as to be opened automatically by the air flow.

[Also in Division G1] To measure the speed of decomposition of a synthetic polymer the sample 11 is heated in a thermolysis chamber 5 to a thermolysis temperature, the thermolysis products are entrained in an inert scavenging gas, e.g. helium, flowing through the chamber at constant flow rate, the effluent is oxidised in a chamber 15 to covert the products to carbon dioxide and water vapour, the water vapour is then absorbed in column 23 to eliminate it from the effluent, and finally the concentration of the carbon dioxide in the remaining effluent is measured and gives a direct measurement of the speed of thermal decomposition of the polymer. The oxidation is generally carried out over a catalyst such as activated or pure copper oxide with e.g. phosphoric anhydride deposited on pumice stone as the water vapour absorbent. The carbon dioxide concentration can be measured by measurement of the thermal conductivity (as with device 24), or by flame ionisation, infrared absorption, or mass spectrometry.

Abstract: 962, 655. Cooling reactors. BABCOCK & WILCOX CO. Sept. 8, 1960 [Sept. 10, 19591, No. 30981/60. Heading G6C. In a pressurized water nuclear reactor the water pressure is maintained at a constant value by means of a vessel, connected to the water system, which accommodates changes in the water volume due to alterations in its temperature. As shown, water is circulated through the reactor 9 and the heat exchanger 13 by the pump 15. The spherical vessel 12 is connected to the circulating system through pipe 16 so as to partially fill with water. The upper volume of 12 contains steam generated by vapourization of the water in 12 by the electric heaters 14. Expansion of the coolant water causes a flow of water into 12 and a consequent reduction of the steam volume. A contraction of the coolant water causes an expansion of the steam volume and the steam pressure is such as to prevent boiling of the water within the reactor. To limit pressure rises, cool water may be sprayed into the upper portion of vessel 12.

Title: Improvements in shock absorbers for railway vehicles
IPC: F16F9/48
Filed: 1927-11-18
Abstract: 280,949. Lotte, L. Nov. 19, 1926, [Convention date]. Fluid-friction vibrationdampers.-In a one-way hydraulic shock - absorber adapted to check the rebound of the springs in railway rolling stock, the motion of the piston is arrested bv the first tendency to displacement and flow of liquid is permitted after an appreciable time interval. A chambered piston B slides in a cylinder A and is free to move upwards under the influence of a spring D which acts on a valve E seating in the lower end of the piston. Liquid then flows freely from the interior of the piston to the cylinder through the central tube F and the ports J. The tube F forms part of the cylinder and the valve E slides on it. The rate of flow of liquid from the cylinder to the piston is regulated, during downward movement of the piston, by a member L at the upper end of a stem K having a bell-shaped piston N of larger diameter at the lower end. When the piston B is forced downwards, the rise of pressure in the cylinder A forces the piston N and stem K downwards until the piston bears on the plug I; the member L then closes the passage in tube F and locks the apparatus for a short interval. Air trapped inside the piston N is compressed during this action and liquid passes through the groove M in the piston N to equalize the pressures so that the piston N rises and the member L moves slightly out of the tube F and allows slow leakage of liquid upwards, the piston B consequently moving slowly downwards. The range of movement of the piston N may be varied by screwing the plug I in or out so as to vary the length of the interval between complete stoppage of the piston B and the commencement of the slow movement.

[Also in Division C3] Trioxane is separated from a mixture of trioxane and polyoxymethylene by treating the mixture with gaseous trioxane or a mixture of at least one inert gas and trioxane in which the partial pressure of trioxane is at least 60 mm. of mercury, the trioxane or the mixture thereof with the inert gas being at a temperature of from 65‹ to 130‹ C. In a preferred embodiment the process is performed in a vertical tower into which the polymer is inserted for extraction and in which a flow of gas melts and subsequently evaporates the remaining monomer. The temperature of the incoming gases is adjusted to 120‹ C. by a heat exchanger at the bottom of the tower. After becoming charged with trioxane, the gas flows into a cyclone where the drops melted at the beginning of the process are collected, and then into a condenser where some of the trioxane vapours condense. The gas leaving the condenser is taken up by a superheated fan and recycled at the head of the tower.

Abstract: 877,626. Superconductor modulators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 30, 1958 [Sept. 30, 1957], No. 31160/58. Class 37. A super conductor modulator comprises, as shown in Fig. 2, a sheet of a suitable superconductor material 16, preferably tantalum held at such a temperature that, in the absence of a magnetic field, it is superconducting, having coils .14 and 18 mounted one on each side of the sheet their planes parallel to the sheet, and a conductor 22 passing through the centres of the coil and through hole 20 in the sheet. The superconducting sheet 16 effectively screens coil 14 from 18, however application of a signal from source 13 to conductor 22 produces a magnetic field around conductor 22 which takes a surrounding portion of plate 16 from its superconducting to its resistive state and allows signals to be transmitted, via magnetic coupling between coils 14 and 18, from source 10 to utilization circuit 12. The current in conductor 22 therefore modulates the signal passing between coils 14 and 18 without there being any direct coupling between conductor 22 and coils 14 or 18 since the conductor 22 is perpendicular to the plane of the coils.
