Title: Improvements in heating arrangements of railway carriages
IPC: B61D27/00
Filed: 1932-11-02
Abstract: 392,085. Heating vehicles ; supplying feedwater. MIELICH, A., 35, Hallesches Ufer, Berlin. Nov. 2, 1932, No. 30932. Convention date, Dec. 11, 1931. [Classes 64 (ii) and 123 (ii).] Railway-carriage radiators are heated by an electrically heated boiler 1 to which condensed water is returned through an auxiliary heated chamber 23 divided into two compartments 10, 11. Water returns to the top compartment 10 and passes a valve 18 controlled by a float 17 into the compartment 11 where it is electrically heated by an element 16 until pressure overcomes a spring-loaded valve 19 and water returns to the boiler 1. The element 16 is controlled by the float 17, and the valve 18 may be opened against pressure by leverage of the float 17. The valves 18, 19 may be interconnected. Steam passes from the boiler 1 to a ball valve 6 which may shut off a locomotive steam pipe 4 or the boiler 1. The admission of the steam to the radiator is controlled by a valve 7, and condensed water returns past a valve 21 which allows escape of water only if locomotive steam is used, by a pipe 22 to the compartment 10. Any steam formed therein passes through a pipe 20 and returns by the pipe 22. During cold weather additional heating means, e.g. a steam coil 12 which can be turned on when the compartments are emptied, is controlled by a valve 12a connected with draining cocks 13, 13a.

To allow filling of a cable, a plug 3 is secured to the insulated core 2 after it is dried and the sheath 19 is then applied, under vacuum, forming an air-tight joint with the plug 3, access to the cable interior being then obtained by piercing a metal diaphragm 10 in the plug 3. Vacuum conditions are maintained in the cable interior by connecting a vacuum pump to the channel 20 which leads to a groove 6 between seals 5, 5<SP>1</SP>. The diaphragm is pierced by a member 14 moved by a hand wheel 18, vacuum conditions being maintained around the member 14 by bellows 16. To draw oil into the cable via pipe 13 a similar plug at the other end of the cable provides a connection for a vacuum pump.

Title: Organic zirconium compounds
Inventor: EMBLEM HAROLD GARTON
IPC: C04B33/13
Filed: 1961-08-31
Abstract: Refractory articles are made by mixing a liquid composition comprising a zirconium ester of formula Zr(ORX)4 where R is C2-4 alkylene and X is Cl, Br or I and an aliphatic hydroxyamine containing up to 12 carbon atoms with water or a solution of water in a mutual solvent for water, the ester and the amine so as to cause the formation of a gel, adding to the liquid prior to gel formation a refractory powder such as zircon or alumina, shaping the resulting mixture, allowing to gel, and the shape to harden and then firing. Preferred amines are of type R1NHR2 where R1 is C2-4 hydroxyalkyl and R2 is hydrogen or C1-4 alkyl or hydroxy-alkyl. In examples, crucibles are made, firing temperatures being 1000 DEG  C. for zircon and at least 1400 DEG  C. for alumina.ALSO:The invention comprises zirconium esters of formula Zr(ORX)4 where R is C2- 4 alkylene and X is Cl, Br or I.  They are prepared by reacting ZrCl4, ZrBr4 or ZrI4 with a C2- 4 epoxy-alkane. An inert solvent may be used.  Compositions with aliphatic hydroxyamines may be hydrolysed to form gels (see Division C4) which may act as binders for refractory powders in making refractory articles (see Division C1).ALSO:Adhesive gel-forming compositions comprise a zirconium ester of formula Zr(ORX)4, where R is C2-4 alkylene and X is Cl, Br or I (for preparation see Division C2) and an aliphatic hydroxyamine containing up to 12 carbon atoms, the amount of the hydroxyamine being such that the composition is capable of forming a gel by hydrolysis.  Preferred amines are of the type R1NHR2, where R1 is C2-4 hydroxyalkyl and R2 is hydrogen or C1-4 alkyl or hydroxyalkyl. Gels may be formed by addition of water alone, but it may be necessary to use a solution of water in a mutual solvent for water, the ester and the amine, e.g. a lower aliphatic alcohol.  Some solvent may be included in the mixture of ester and amine.

Abstract: 996,029. Fluid-pressure servomotor systems. R. MARTINON, and H. CABIGO. Aug.16, 1962 [Sept. 28, 1961], No. 31484/62. Heading G3P. The supply of water to a horticultural sprinkler is controlled by a main valve 38, Fig. 1, with a port 40 therethrough whereby the chamber behind the valve is open to the water inlet 35; the chamber is connected to outlet 36 and flow thereto is regulated by an auxiliary valve 45 actuated by a float 23 either hollow or made from a light-weight material e.g. polystyrene, through a permanent magnet 30 separated from the valve 45 by a diaphragm 33. The float 23 is housed in a double-walled vessel 10, the annular space 14 between the walls incorporating ports 15 leading into the bottom of the float chamber, and wicks 18. An adjustable spray nozzle directed on to the float-chamber lid 21 is connected to the outlet 36. With the float chamber empty the magnet 30 contacts the diaphragm 33 and magnetically unseats the auxiliary valve 45 so that the main valve 38 is opened by the supply pressure whereby water is led to the sprinkler and spray nozzle; water from the latter runs from the lid via the space 14 into the float chamber. The float 23 is lifted and the auxiliary valve 45 closes causing the main valve 38 to seat. Water in the float chamber evaporates from the space 14 directly and through the wicks 18 until the water level in the float chamber has reduced sufficiently to enable the magnet 30 to again open the auxiliary valve. A bimetallic strip 70 holds the float in the raised position so preventing operation of the sprinkler when the ambient temperature is above a given level.

Abstract: 749,549. Regenerative heat-exchangers. SVENSKA ROTOR MASKINER AKTIEBOLAG. Nov. 13, 1953 [Nov. 14, 1952], No. 31522/53. Class 64(1). Relates to rotary-matrix type regenerative heat-exchangers in which the rotor 10 rotates on a vertical axis within a stationary housing including a central member 18 separating two end plates 24, 26 apertured to allow the heatexchanging fluids to flow through the rotor in the usual manner. According to the invention, the upper end plate 24 is rigidly connected to an upper support beam 14 preferably by a tubular member 25, the lower end plate 26 is rigidly connected to a lower support beam 28 preferably by a tubular member 27, and the central housing portion 18 is connected to both beams through spaced vertical members 20 which are rigidly secured to the housing portion 18. This arrangement permits relative movement between the housing 18 and end plates necessary under operating conditions, and leakage, due to this movement, at the joints between the end plates and the end faces of the housing portion 18 is prevented by the provision of flexible seals. In Fig. 5, the seal comprises an annular bellows 33 extending between the end plate and a flange 35 on the housing 18 as shown. Pins 37 extending from the housing 18 are received in radially-extending slots 36 which allow radial expansion and relative radial motion between the upper end plate 24 and the housing member 18 while at the same time preventing relative transverse motion. Fig. 6 shows an alternative seal comprising an annular member 61 of U-shaped cross section. As shown in Fig. 1, the preferred arrangement is such that the rotor 10 and the housing are independently suspended from the upper support beam 14 which in turn is supported by girders 16. The spaced vertical members 20 are connected at their ends to the beams 14, 28 through links 21 or alternatively Fig. 4 (not shown), links 21 are omitted and the entire structure is carried on feet secured to the vertical members 20.  Reference has been directed by the Comptroller to Specification 719,173.
