Title: Improvements in and relating to means for cooling the cylinders of internal combustion engines
IPC: F01P3/22
Filed: 1936-04-29
Abstract: 468,535. Cooling cylinders. RABATEL, H. A. April 29, 1936, No. 12225. Convention date, April 29, 1935. [Class 7 (ii)] Air-cooled ribs 2, radiating from a cylinder, are surrounded by a cooling-liquid jacket 3, the temperature of different parts of the cylinder being thus equalized. Air, blown across the cylinder head through ports 5<1>, draws a further stream up the cylinder as shown by the arrows f<1>. Circulation in the jacket 3, which may be streamlined and arranged in the slip stream of an aircraft propeller, is produced by baffles 6 or by a pump. External cooling ribs 7 may be provided, and the ribs 2 may extend to the base of the cylinder. The cooling-liquid may be ethyleneglycol.

Abstract: 1177653 Super-conductors IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 6 March 1967 [21 March 1966] 12242/66 Headings H1A A5 and A4D A composite conductor is produced by mechanically working the constituents of a superconducting compound and a "normal" metal selected from copper, aluminium, silver and indium to form one or more filaments or layers of the constituents in the normal metal and then heating to form the super-conducting compound. In one embodiment, molten tin is poured into holes in a niobium cylinder which is placed in a copper extrusion can; the whole is evacuated, extruded and drawn into 0À0104 inch diameter wire which is heated at 985C for one hour to form Nb 3 S n  at the interface. If described, annealing heattreatment may be applied at an intermediate stage in the drawing. Alternatively the tin may be in rod or powder form or a compacted powder rod of Sn and Nb may be inserted. Other embodiments comprise (i) Nb and Sn foils rolled around a Nb or Sn rod (ii) a coil of Nb or Sn in a copper container with the other constituent poured in (iii) a block of "normal" material with holes into which Nb and Sn are inserted and (iv) a pair of Nb and Sn foils sandwiched between copper foils. In each case the assembly is extruded, drawn or rolled to provide composite wire or thin strip and heated to form the super-conducting compound. Quoted examples of suitable compounds are Nb3Sn, V3Ga and Ta 2 Sn.

Abstract: 312,770. Marks, E. C. R., (Riley Stoker Corporation). April 26, 1928. Air supply, regulating.-The air supply to the fuel surface of underfeed stokers particularly those of the multiple retort type having moving side walls with tuyeres mounted thereon is regulated by specially arranged dampers adapted to control the air supply to different parts of the fuel bed. As shown in Figs. 1, 2 and 5 tha reciprocating retort side walls 24 supporting the tuveres 25 are hollow and extend downwardly for a short distance into the air supply chamber 52 from which the air flows into the hollow side walls and tuyeres. The hollow walls are divided into compartments by transverse partitions the supply of air to each compartment being controlled by a damper 60 loosely pivoted on a rod 64 mounted in the partition walls. The dampers have downwardly extending arms 66 connected by a rod 67 and a series of the dampers extending across a transverse zone of the furnace are interconnected by an actuating rod 70 loosely engaging by means of notches 71 with the damper rods 67. This arrangement permits reciprocation of the retort walls and dampers relative to the actuating rods 70. Specification 1067/13 is referred to.

Filed: 1937-05-03
Abstract: 479,819. Electric welding. ROCCHI, V. May 3, 1937, No. 12618. Convention date, May 29, 1936. [Class 83 (iv)] In a machine for electrically welding tubes of ferrous metal, two pairs of current con. ducting rollers forming four separate electrodes are used provided with interchangeable connections so that any two electrodes may be connected at will to the positive or negative poles of the current source. The electrodes may be water cooled. For large diameter tubes external and internal electrodes are used, the outer electrodes consisting of conducting rolls 9, 9<1>, Fig. 4, separated by insulation and connected by rows of sockets and plugs 21, 22 and leads 2<1> to the current terminals. The internal electrodes consist of conducting rolls 7, 7 <1>, Fig. 3, separated by insulation and carried by an arm 3 in two portions separated by insulation and provided with sockets for plugs 19, 20 connected to the current source by leads 2. The plugs may be interchanged so that for butt welding the current may pass mainly cross-wise from the outside to the inside rollers, Fig. 6, to heat the vertical edges of the tube, whereas for parts with inclined overlapping edges, the upper rollers may both be positive and the lower rollers negative. The arm is jointed at one end to a slide 5 so that the electrodes 7, 7' may be inserted in the open tube, a tension screw 6 applying welding pressure. The slide carries a guide roller 10. The tube is fed by two pairs of adjustable rolls 11, 13, 14, and is supported by an idle roll 15, and the seam is closed by driven side rolls 16 and roll 18 at the welding point. For small diameter tubes, the internal electrodes and rolls 16, are replaced by a pair of external electrodes 25, 25<1>, the lower parts 23, 24 of which are of insulating material. These rolls also co-operate with the roll 18 to close the seam. The electrodes 25, 25<1> are mounted in arms 3<11> provided with sockets for plugs 19, 20, current being conducted to the electrodes by brushes 26, 27. Switches may be provided so that the machine may be used either for continuous or for spot welding.

Title: Telephone system

Filed: 1967-03-17
Abstract: 1,129,485. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 17 March, 1967 [22 March, 1966], No. 12666/67. Heading H4K. A telephone exchange comprises a plurality of similar modules each incorporating a network of solid state crosspoint devices, a register adjusted to receive a first group of digits of a subscriber dialled number and means to respond to complete the switching indicated by said group and to clear the register for the reception of further digits of the number. The switching is effected in a rapid manner and can be completed during an interdigit period thus a four digit register can deal with numbers of any length. As described the networks are as described in Specification 953,895 and each comprises an array of PNPN diodes. A potential difference applied between a marked inlet and a marked outlet during a time slot associated with the inlet, effects selection on a self-seeking basis, the first path completed removing the potential difference thus preventing the completion of further paths. Figure 2 shows a module including such a network 20. In the event of a call from a local subscriber associated with a line circuit such as 21 a path is completed through the network 20 to a local junctor 23. The local junctor is one of a plurality of control circuits 22 which sequentially mark the outlet side of the network under the control of an allotter 28. A free local register 30 is selected and connected to the local junctor 23 through an auxiliary switching network 31. When the first three digits have been dialled into the register they are applied to a translator 34 which determines whether they represent a local code or a distant code. If they represent a local code, the register 30 is cleared and receives the remaining four digits identifying the wanted subscriber. When these have been received they are applied to the translator which enables the line circuit of the called subscriber over busses 33. A path from the terminate side T is thus effected through the network 20 to the line circuit of the called subscriber. If the first three digits represent a distance code an outgoing trunk 26 is selected by a trunk allotter 37 and the code is transmitted to another exchange or module, subsequent digits being dialled direct into that exchange or module.
