Title: Improvements relating to nuclear reactors
Inventor: DEIGHTON THOMAS
IPC: G21C1/08
Filed: 1960-01-20
Abstract: 887,252. Cooling reactors. BABCOCK & WILCOX Ltd. Jan. 13, 1961 [Jan. 20, 1960], No. 2069/60. Class 39(4) [Also in Group XIII] A reactor has an emergency heat exchanger in a cooling circuit which is normally ineffective and through which convective flow is caused by expansion of liquid in the main cooling circuit of the reactor. The pressurized water reactor shown is connected by a riser 12 to an electrically heated pressurizer 13 into which water can be sprayed at 25. If cooling of the reactor by the main circuit fails, thermal expansion makes the water level 18 in the pressurizer rise until it reaches a pipe 14; convective flow can then begin in a circuit including pipes 12 and 14 and a heat exchanger 15 which loses heat to a heat sink, e.g. the sea. If the reactor is isolated by valves 20, 23, convective flow through the core can still take place by way of holes 22 or control rod channels.

Abstract: 100.709. Durand. A. Feb. 11. 1916. Hand-irons; steaming and damping apparatus.-Pressing-irons equipped with steam-generating means for damping the fabric are fitted with special valve mechanism for regulating the supply of water to the steam-generator. In the construction shown, the iron is heated by a gas burner 4 supplied through a valved mixing-pipe 9 working on the Bunsen system, but other heating-means may be used. The combustion chamber is in the lower portion of the iron and is provided with side and rear air-holes. The steam chamber 22 in the upper portion of the iron is provided with gills 23 and delivers steam to the fabric through a strainer 20 and passages leading to holes 17 arranged in the toe of the iron, as shown in Fig. 4. The water supply comprises a valved pipe 27 passing through the handle and delivering into a chamber 35 through minute holes in the piston 43. On depressing the press-stud 41 against the action of the spring 44, the valve 46 is opened and the piston 43 acts as a pusher to force the accumulated water into the steam chamber. The pressure of the steam closes a ball valve 50 and prevents steam from passing back into the water-pipe.

Abstract: 162,093. British Thomson - Houston Co., Ltd., (General Electric Co.). Jan. 27, 1920. Induction motor relays; protective arrangements.-An induction-type relay comprising an induction disc 5 moving between opposed electromagnets 1, 3 is given an inverse time-characteristic up to a certain value of current above which the time-characteristic is constant irrespective of the current by exciting the winding 6 of the electromagnet 1 by a resultant voltage derived from a transformer 10 excited by the primary winding 11 from the current transformer in the protected line, the resultant voltage being a measure of the primary current up to a predetermined amount and thereafter constant. As shown, the winding 6 is excited by the transformer winding 8 through the adjustable resistance 15 across which an opposing voltage is impressed derived from the connection of the resistance 15 in the adjustable primary circuit 11 of the transformer. Up to a value of current sufficient to saturate the transformer 14. the current in the operating-winding 6 varies with the load current and, consequently, the time of operation of the relay varies correspondingly. Above that current, the opposing voltage at the resistance 15 maintains the current in the winding 6 and, consequently, the time of operation of the relay constant.

Title: Improvements in or relating to steering control mechanism for aeroplanes
IPC: B64C13/00
Filed: 1931-01-26
Abstract: 371,922. Aeroplane controls. PETERSEN, A. G., 318, Ovington Avenue, Brooklyn, New York, U.S.A. Jan. 26, 1931, No. 2578. Convention date, Jan. 25, 1930. [Class 4.] The aileron controls of an aeroplane are so arranged that whilst sidewise movement of a control lever causes differential movements of the ailerons forward or rearward movement of the lever to cause up or down movements of the elevator also causes simultaneous downward movement of both ailerons, combination movements of the lever causing combination movements of the ailerons and elevator. A shaft 14, Fig. 1, is mounted transversely in the machine and is free to rotate in bearings in longitudinal fuselage members 17. A lever 15 is pivotally mounted on shaft 14 so as to be capable of sideward movement in the plane of the shaft 14. Shaft 14 and lever 15 are rocked by a column 18 mounted on the shaft and the lever 15 is rocked about its pivot by chain and sprocket connections between the upper end of the lever and a hand-wheel 19 on the column. Rods 37 connected to levers 35, the effective lever arm of which can be varied, on shaft 14 operate the elevators. Universally jointed to the outer ends of shaft 15 are triangular frames 25, of which the lower inner apices are interconnected by a rod 23 connected at 16 to lever 15, and the outer apices connected by rods 29 to operating arms 31 on ailerons 12. From Fig. 2 in which the ailerons are shown turned through 90‹ it will be seen that transverse movement of lever 15 causes one aileron to move upwardly and the other to move downwardly through a greater angle. From Fig. 3 it will be seen that rotating shaft 14 to operate the elevator also causes fore or aft movement of the lever 15 producing downward movement of both ailerons, this movement being very small for normal elevator movements. According to modifications the connecting-rods 29 are pivotally connected to the ends of bell-crank levers rocked about pivots disposed on upwardly, Fig. 8, or downwardly directed radial arms formed on the transverse shaft by means of pull and push rods connected to lever 15. The lengths of levers and links may be adjusted to give equal aileron movements for given sidewise displacements of lever 15.

Abstract: 1450821 Forming grooved bell ends on pipes JOHNS-MANVILLE CORP 21 Jan 1974 [23 Oct 1973] 2684/74 Heading B5A [Also in Division F2] An internal groove is formed in the bell end of a PVC pipe by pushing the pipe over a hard rubber sealing gasket projecting from a supporting core so that a groove is formed by the gasket, and then deforming the groove (see Fig. 12) to reduce its extent. The gasket is left in the groove or can be replaced; several gaskets and retaining members can be used. As described, the gasket 26 (Fig. 10) is seated in a recess of a lubricated and heated steel core 54. A plurality of pivoted ramp bars 68 are projected from the core by rods 73 actuated by a frusto-conical surface 71 (Fig. 5). The heated pipe end is pushed over the core, ramp bars and gasket until it meets a stop 56, whereafter the ramp bars are spring retracted flush with the core (Fig. 12) and the pipe end is drawn on to the core by suction and air pressure. A plurality of plungers 90, 104 mounted on an annular support 72 (Fig. 5) are operated by pistons or linkages to deform the pipe groove about the gasket (Fig. 12) to lock the gasket in position. After fluid cooling, the pipe is withdrawn from the core, with the gasket riding up an inclined surface of the core recess. The plungers 90, 104 comprise a plurality of straight edged members 94 (Fig. 7) that form a plurality of opposing or staggered locking projections in the pipe. Alternatively, arcuate plungers form a continuous locking projection adjacent the groove edges or in the body of the groove.
