Filed: 1929-09-14
Abstract: 319,015. Electrolux, Ltd., (Assignees of Lenning, A.). Sept. 15, 1928, [Convention date]. Refrigerating, absorption machines for.-In continuous-cycle inert gas systems, means are provided for varying the proportion of circulating refrigerant to inert gas during operation, in order to vary the capacity in accordance with the load. In the apparatus shown, comprising the known arrangement of generator 1, rectifier 3, condenser 4, refrigerant receiver 6, heat exchanger 10, evaporator 11, and absorber 13, with connecting pipes, a dish 23 is arranged at the bottom of the absorber, with its rim above the bottom of the return pipe 12 from the evaporator, so that refrigerant or strong solution from the evaporator may be trapped in the space 24, which communicates with the inside of the dish only by a restricted opening 26. While the trap is full the liquor in circulation is weakened and the capacity of the machine is increased. As soon as the load is reduced and the whole of the circulating refrigerant is being evaporated, the trapped portion gradually passes back into the circulating cycle and normal conditions are restored. In place of the dish, a transverse baffle or dam may be used. A baffle may be arranged to direct the falling liquor into the dish.

Filed: 1924-11-21
Abstract: 225,543. Soc. Anon. Eternit Pietra Artificiale. Nov. 26, 1923, [Convention date]. Moulding pulp.-In the production of seamless pipes of fibrous matter, such as asbestos fibre and hydraulic cement, means are provided to give a uniform pressure along the whole length of the pipe during its formation, so as to eliminate equally the surplus water which hinders the setting of the cement. The pressure rollers D are carried by hydraulic rams working in cylinders A and these rams also carry a beam B on which is mounted supplementary pressure rollers E which distribute their pressure equally over the pressure rollers D. The formed tube F is supported by a lower roller G and apron M, and another apron K passes around the pressure rollers, which are driven independently by gearing P, 0, of which one of the intermediate gears 0 is mounted on a link carried by the centres of the gears P and one of the rollers D. In a modification, the supplementary pressure cylinders are dispensed with and supplementary rollers E are carried directly by the beam B at distances from the ends of the pressure rollers equal to 0.21 of their lengths. In a further modification, the supplementary rollers E, instead of being carried by the same cross frame, are carried on each side by independent inclined rams of supplementary cylinders C, which are also mounted on independent beams B, Fig. 5. In a further modification, a single pressure roller D only may be employed, and double support rollers beneath the formed cylinder, the supplementary pressure rollers being situated at regularly disposed intervals or at two positions only similar to the arrangement shown in Fig. 3. In a further modification, the pressure from the hydraulic cylinders A may be transferred to the pressure rollers by means of internal bearings V, Fig. 10. As the diameter of the tube increases the pressures in the cylinders A and C are decreased.

Title: Improvements in or relating to methods for generating steam in forced-flow boilers and to apparatus for regulating such boilers
IPC: G05D16/20
Filed: 1955-09-30
Abstract: 798,243. Automatic control systems for boilers. ZUPPKE, B. Sept. 30, 1955 [Sept. 30, 1954], No. 27973/55. Class 38 (4). In a control system for a forced flow boiler, the fuel supply to the boiler is automatically regulated in dependence on variatinso of water pressure in a water section of the boiler. In Fig. 2, water supplied to a forced-flow boiler through a conduit f passes through an economizer a to a radiation heater b in which it is converted into steam which passes through a supercharger d and a reheater e on its way to a discharge conduit g. Conversion to steam may be completed in a further heater located with the economizer and reheater and connected between the radiation heater b and superheater d. Outlet steam pressure is maintained constant by a pressure detector i controlling a valve h in the discharge conduit. Changes in inlet water pressure at a point P1, consequent upon a change in the relationship between the rate of supply of heat and the rate of supply of feed water are detected by a flow meter Mo, in. a conduit between the inlet and discharge conduits, which controls a rheostat M<SP>1</SP>0 in a bridge circuit, Fig. 2a, to energize a two-way relay r and thereby operate a motor RM in the appropriate direction to alter the supply of coal dust to burners I by adjustment of a speed regulator RK for a motor MK driving a fuel distributer K. Alternatively the pressure in the inlet conduit at P1 may alone control potentiometer M<SP>1</SP>0. To compensate for variations in load on the boiler a flow detector Q in the inlet conduit operates a potentiometer Q<SP>1</SP> to alter the balance point of the bridge circuit. A detector T responsive to the temperature of steam in the discharge conduit adjusts a rheostat T<SP>1</SP> to prevent temperature deviation beyond predetermined limits. Discharge pressure detector i may control the supply of fuel and feed water instead of valve h to maintain constant discharge pressure.

Abstract: 191,838. Freeman, S. Oct. 21, 1921. Mats.-Blocks f, Figs. 1, 2, and 3, of resilient material of circular or polygonal cross-section, are threaded on bars, rods, or tubes a, which are carried between two sides only of a boundary frame c. The blocks have a number of tread surfaces g, each of which can be exposed to wear by rotating the rod &c., and by splitting the block into a number of sections, local wear may be distributed by rotating some of the sections on their rods, or by redistributing them if the rods are square. The rods may be spaced near enough to permit the interlocking of adjacent blocks, and they may be curved, as shown in Fig. 8, to form a quadrantal mat. The blocks rest on the floor and support the frame clear of the floor to permit drainage. The frame may be made of sheet metal, as shown in Fig. 7, with holes e and alternate lugs d bent to position the rods and pressed back to fix them. The metal frame may be replaced by a non-articulated frame of flexible material, Fig. 10, showing the bars a provided with pins m to engage with the flexible frame ends, as shown in Fig. 12, and the ends being held together by tenoned side pieces. Hook bolts k and wing nuts l fix the mat in position. If the blocks are of different colours, variable patterns may be produced. The mat may be used on the running-boards of motor-cars.

Abstract: 158,712. Pelling, E. R., and Mattick, V. A. Nov. 12, 1919. Ploughs. - A motor-propelled anti-balance plough is provided with a tractor frame e on which the plough frame a is pivoted by a draw-bar c vertically adjustable in hanging brackets d and projecting through the inclined slots b<1> in the central blocks b of the plough frame. The plough frame is hauled by cables f extending to the brackets d. The plough frame at each end is further connected to the tractor frame by a cable or chain h which is attached to the end of the plough frame, passes over a pulley or sprocket m on the tractor frame and a second pulley n secured at approximately the middle of the plough frame and is then attached to the tractor frame. When the plough is reversed at the headlands, as the tractor frame moves relatively to the plough frame the one cable automatically lifts the inoperative plough frame while the second cable is relaxed, allowing the other plough frame to engage the ground. To assist the shares in penetrating the ground, the plough frame may be positively tilted by turning the sprockets m by hand-levers o which engage the sprocket-wheels through one-way clutches.

IPC: G21C3/32
Filed: 1962-07-24
Abstract: 1,035,487. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. July 1, 1963 [July 24, 1962], No. 28407/62. Heading G6C. An elongated fuel element for axial insertion into a coolant-conducting passageway of a nuclear reactor carries at least three lateralsupport members free to be displaced radially outwards by coolant flow along the passageway so as to reach the wall of the passageway and restrain any tendency for coolant flow-induced vibration of the fuel element. In the embodiment described (Fig. 2, not shown), the fuel element 1 comprises a cluster of sheathed fuel rods 23 end-located in grid-like support structures 24 and housed in a graphite sleeve 25. An annular support 28 attached to an extension 25a of the sleeve 25 carries six pairs of downwardly extending brackets 30 between which six support members 4 are pivoted. The fuel element 1 is shown in the act of being axially inserted, under load, into a vertical standpipe 6 of a gas-cooled reactor, the coolant flowing upwards and displacing the members 4 radially outwards so as to reach the wall of the standpipe 6 and thus give lateral support to the fuel element. Movement of the members 4 is limited by pins 38 projecting upwards from a lower annular base 35 through longitudinal slots 40 in stop members 39 carried at the lower ends of the members 4. The annular base 35 is attached by webs 37 to a boss 36 at the lower end of a column 32 extending downwardly from a boss 33 attached by webs 34 to the annular support 28. The fuel element 1 is raised and lowered by means of a grab suspended by a cable from a hoist disposed within an " on load " charge machine on the charge face of the reactor, the grab engaging with the upper end of a tie-rod 26 which extends through the fuel element. The reactor 2 (Fig. 1, not shown) is connected by coaxial ducts 14, 15 to a heat exchanger 16 and a blower assembly circulates reactor coolant (CO2 gas) through the annular space 18 between the ducts 14, 15, down between the core 7a, 7b and the pressure vessel 8 and, optionally, down through channels (not shown) between adjacent graphite blocks of the core 7a, 7b and through annular channels between the graphite sleeves 25 and the walls of the fuel channels 9, up through the graphite sleeves 25 to cool the fuel rods 23, into a header vessel 10 and from thence to heat exchange elements 19 within a heat exchanger 16 by way of the duct 14.

Title: Improvements in arrangements for controlling the damping of oscillatory circuits
IPC: H03G5/26
Filed: 1939-10-23
Abstract: 533,253. Automatic selectivity control. PHILIPS LAMPS, Ltd. Oct. 23, 1939, No. 28509. Convention date, Oct. 25, 1938. [Class 40 (v)] Relates to selectivity controls for radio receivers of the kind in which a control voltage is used to vary the damping effect of a diode valve on a tuned circuit, and consists in varying the bias on the diode by means of resistances acting as load resistances to that diode and to a second diode fed from the output of a valve the amplification of which is controlled in accordance with the control voltage. As shown, the damping diode 2 is connected in series with a resistance 3 across the oscillatory circuit 1. This is coupled to the grid circuit of an amplifier 6 having a band-pass output circuit 11, 12 across which the second diode 13 is connected through a resistance 15, 17. The amplifier gain is determined by an A.V.C. connection 19, and with normal signal strength, the voltage of the junction of resistances 15, 17 is equal to that of the cathode end of resistance 3. With louder signals the gain is reduced, and rectified current flows through the diode 2 to both resistances 3 and 17, giving increased damping and less selectivity ; with weak signals the opposite effect is produced. By rearranging the elements, all the cathodes may be earthed, and the two diodes and the triode may use a common cathode in a single tube. The circuit 1 may be inductively coupled to the grid circuit of the amplifier, and the three resistances 3, 15, 17 may be replaced by a single resistance in the lead to the common cathode. A tapping on this resistance may feed the rectified low-frequency signals to an amplifier, and an A.V.C. voltage may be taken off through a filter.
