Title: Improvements in turbine locomotives provided with a device for supplying steam for heating purposes
IPC: B61D27/00
Filed: 1922-04-10
Abstract: 179,153. Krupp Akt.-Ges., F. April 29,1921, [Convention date]. Heating vehicles. - In a heating system for railway trains in which the steam is supplied from a turbine locomotive, the supply pipes g, h are connected to the turbine at points 1, 2, 3 at which the steam has performed a portion of its work and its pressure has been reduced to the desired value. In the arrangement shown, a three-way valve a operated from the driver's cab connects the steam-supply pipe g with the forward-driving turbine, while the steam-supply pipe h connects with the backward-driving turbine, both pipes g, h being fitted with automatically closing check-valves c so that the valve closes in the pipe not in use and prevents backflow of steam or air into the turbine. The steam passes from the pipes g, h into a valve-body i, to which a steam-supply pipe d from the driver's cab is also connected, and then by a pipe e to the heating-conduit f. If the pressure falls below the desired value, steam flows into the conduit f from the pipe d through a reducing-valve k. A valve in the body i prevents access of steam to the pipe e when the heating by steam is entirely cut off.

Title: Polymerized nitriles and processes of preparing the same
Filed: 1937-04-10
Abstract: Aliphatic straight-chain nitriles containing at least 5 carbon atoms are polymerized to oily products by treatment with a chloride of aluminium, zinc, iron, tin, sulphur or phosphorus, or phosphorus pentasulphide or sulphur or phosphorus.  A solvent such as kerosene or an aromatic hydrocarbon may be present, which to some extent may combine with the polymer.  Suitable nitriles are capro-, caprylo-, capri-, lauro-, myristo-, palmito-, and stearo-nitriles, and the nitrile mixtures made by cracking nitriles of high molecular weight. Examples describe the polymerization by means of aluminium chloride of mixed palmito- and stearo-nitriles, the mixed nitriles from cracked cotton-seed fatty acid nitriles and from cracked stearo-nitrile; and the nitriles of lard fatty acids alone or in the presence of kerosene and naphthalene or of naphthalene only.  The process is effected similarly with the other catalysts specified. When sulphur- or phosphorus - containing catalysts are used, the product may contain traces of sulphur or phosphorus.  More than one of the catalysts may be used, for instance, a mixture of sulphur and aluminium chloride.

Abstract: 662,976. Spinning and winding thread. COURTAULDS, Ltd., and CURTIS, G. April 18, 1950 [April 19, 1949], No. 10311/49. Class 120(ii) [Also, in Group XXIX] In a' spinning or winding machine, particularly a box-spinning machine for viscose rayon threads &c. comprising a number of traversing rails each reciprocating one or more thread guides, the traversing rails are traversed in synchronism by the reciprocatory motion of the pistons in a number of hydraulic cylinders connected in series with a common pressure fluid supply, and the reversal of motion of the pistons is effected by a single reversing valve in the fluid circuit, the operation of the valve being effected by a traversing member. As shown, filaments are fed by godets 8 to traversing funnels 2 to be laid in centrifugal boxes 3, the funnels 2 being attached to traverse bars 1 reciprocated by the pistons 26 of hydraulic cylinders 6a, 6b arranged in series in a casing 7. The cylinders are fed with fluid from a sump 11 by a motor-driven pump 9. the fluid entering a reversing valve 14 by way of pipe 13. and in the position shown, leaving the valve by pipe 15 and moving the pistons in both the cylinders 6a and 6b upwardly by reason of the connection 19. From the cylinder 6b a pipe connection 20 to the cylinder 6 will ensure that, at the same time. the pistons in the next pair of cylinders 6 and 6c will move downwardly. When the rail 1a has reached the top of its motion, it will contact a stop 22 on the spindle 18 of the valve 14 to move the pistons 17, 23 therein to reverse the liquid flow, i.e. pressure fluid will leave the valve 14 by the pipe 16 to move the pistons in the cylinders 6 and 6c upwardly and those in the cylinders 6a and 6b downwardly. Contact of the rail 1a with the stop 25 at the bottom of its motion will effect the next reversal of the valve 14. Displaced liquid returns to the sump through pipes 21, 24. The hydraulic pistons may be spring-loaded to ensure prompt reversal and a port may be provided in each piston rod arranged to allow excess fluid to flow therethrough when one piston reaches the end of its stroke in advance of another. Relief valves 29, 30 are provided on each pair of cylinders and at the pump outlet, respectively. To avoid pattern winding, the rate of flow of liquid to the cylinders may be varied. Specifications 631,857 and 650,366 and U.S.A. Specification 2,427,373 are referred to.

Abstract: 1,145,421. Measuring flame intensity electrically. ROLLS-ROYCE Ltd. Feb.28, 1968 [March 6, 1967, No.10481/67. Heading G1N. The intensity of a flame is calculated from measurements of the rise in temperature and rate of flow of a fluid passing through a conduit held in the flame. As shown, water is forced at high velocity through a spiral conduit 16, Fig. 2, of heat-resistant material, e. g. stainless steel, held in the flame. Two junctions 28, 30 of thermocouple 27, 29 are arranged at the inlet and outlet of the spiral and are connected in series with a meter 32. The rate of flow is measured by meter 33, connected to indicator 34, at the water outlet. Water flows to and from the spiral conduit by conduits 14, 18 surrounded by a water-cooled jacket 23 closed at the end adjacent the flame by an aluminous cement plug 26. A further hot junction 36 of a thermocouple 35, housed in a tube 22 also encased by the jacket 23, is provided at the centre of the spiral to sense the mean temperature of the flame, indicated on meter 41, whereby the calculations from the readings on meters 32, 34 may be checked. The intensity of H of the flame is calculated from the formula H = K(T 2  -T 1  )F where K is a constant, F is the rate of flow of water and (T 2  -T 1 ) the temperature difference sensed by thermocouple 27,29.
