Title: An improved fender for use on motor road vehicles
IPC: B60R19/28
Filed: 1930-11-04
Abstract: 354,637. Collision guards for road vehicles. CARTER, C., 55, Ravensbourne Road, Bromley, Kent. Nov. 4, 1930, No. 33186. [Class 103 (ii).] A bumper for motor road vehicles is formed in a plurality of independent sections extending across substantially the full width of the vehicle and capable of acting together or independently of each other to absorb shocks, each section being resiliently supported, as by compression springs k, on a bar a so that under impact it can move parallel to itself or obliquely. The bar a is fixed to the dumb-irons of the vehicles by stays b and to the front of the bar are secured two pairs of steel or like bars c held by means of knuckle-jointed collapsable elements d, e which may be replaced by or with which may be incorporated shock-absorbing elements. Each spring k is supported between a pair of inwardly projecting lugs f, g. In a modification the supporting bar a is formed with an offset portion to prevent interference with the luggage grid of the vehicle, the sections c have extended bowed portions, and the inner compression springs are made stronger than the outer springs. Reference is made to Specification 339,623, [Class 103 (ii), Rail and road vehicles, Details applicable &c. to].

IPC: C07D201/16
Filed: 1967-07-19
Abstract: 1,175,279. Purification of #-caprolactam. SNIA VISCOSA SOCIETA' NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 19 July, 1967 [27 July, 1966], No. 33197/67. Heading C2C. #-Captrolactam, obtained by the nitrozation of cyclohexyl compounds and containing amidetype volatile bases, is purified by treatment with an alkaline agent in the presence of water and of a halogen or an alkali metal hypohalite to convert the amide-type volatile bases into amine compounds which are then removed. The amine compounds may be separated from the #-caprolactam by use of an ion exchange resin. The crude #-caprolactam may be treated with a stream of gaseous halogen such as chlorine, followed by a solution of an alkali metal hydroxide, and the treatment may be carried out at a temperature of 0 to 70 C. at atmospheric or elevated pressures. The purification may also incorporate other stages already known in the purification of #-caprolactam, e.g. distillation.

Abstract: 1473123 Fluid-pressure control circuits PEINER MASCHINEN UND SCHRAUBENWERKE A G 31 July 1974 [31 July 1973] 33870/74 Heading F1P A pair of actuators 15, 16, Fig. 1, are extended and retracted by a reversible pump 1 and the difference in volumn between the chambers on opposite sides of the pistons is compensated for by returning excess liquid to a reservoir 26 or switching extra liquid therefrom. If the pump is driven to supply liquid to the chambers 11, 12, return flow from chambers 13, 14 is blocked by a pilot-operated check-valve 19 until pressure in the supply line 4 rises to a value high enough to displace a piston 20 through a pilot line 21, so that the valve 19 is opened. Liquid now returns through lines 17, 32, excess returning to the reservoir through a pilot operated check-valve 36, which can open when a pilot line 31 is connected to the reservoir when the piston 20 opens valve 19. If the pump is reversed, pressure in a pilot line 44 opens a check-valve 45 so that liquid from chambers 11, 12 is returned to the pump through lines 9, 4. Extra liquid is drawn from the reservoir through a valve 2. Valves 19, 45 are hydraulically locked against reverse rotation of the pump by pilot lines which lead to both sides of the operating pistons. In the embodiment shown in Fig. 2 liquid from the chambers 11, 12 is returned directly to chambers 13, 14, through lines 29, 28 and pilotcontrolled check-valve 27, without passing through the pump.

Abstract: 1314743 Solid state cells NORTH AMERICAN ROCKWELL CORP 20 July 1971 [21 July 1970 (2)] 34061/71 Heading H1B In a solid state cell having the electrolyte layer disposed between the anode and cathode layers, the cathode contains tellurium tetraiodide or a complex thereof as active electronacceptor material. In these materials the iodine vapour pressure is of no significance and hence the cells may operate in high temperature environments, e.g. 150-200‹ C.; also, since there is essentially no iodine activity cell corrosion is minimized and shelf life is increased. Preferred compounds for forming complexes with TeI 4  are represented by MI and QI where M is K, Rb, NH or a combination thereof optionally including C 5  as a minor constituent, and where Q is a univalent organic ammonium cation. Examples of cathode electron-acceptor material are: Rb 2 TeI 6 .TeI 4 , 4[(CH 3 ) 4 N] 2 TeI 6 . 9TeI 4 . Preferably, the electrolyte contains silver ions and the anode contains silver; however, the anode may contain lithium and the electrolyte lithium ions. In the preferred embodiment, the cathode and anode also contain carbon and the anode additionally contains electrolyte; also, the cathode may contain electrolyte. A typical electrolyte is RbAg 4 I 5 . In one method of making the cell the three layers are deposited in succession upon a substrate by spraying the respective materials in an inert organic solvent, e.g. acetone, and volatilizing the solvent. The cell may be recharged.

Title: Method and apparatus for the generation of steam or other vapour
IPC: B01D1/16
Filed: 1953-12-14
Abstract: <PICT:0764827/III/1> In a distillation process wherein the liquid is brought into direct contact with a finely divided heat carrier material, the heat carrier which, for example, consists of granules of a metal, metal compounds, ceramic substances or graphite of about 1 mm. diameter, is heated in a chamber 7 by the passage therethrough of combustion gases or high temperature waste gases and flows through a lock 3 and a distributer device 4 so that it showers through an evaporating chamber 1.  The liquid to be distilled enters a jacket 2 surrounding chamber 1 through a pipe 11 and passes in a preheated condition into the chamber through atomizer nozzles 13.  The vapour generated by contact with the heat carrier passes upwardly through chamber 1 and is withdrawn through one or more of pipes 16 which are located at different levels to enable vapour to be withdrawn at different temperatures.  The cooled heat carrier discharges through a lock 5, is screened to remove dust and recycled to the heating chamber 7 by means of a conveyer 6.  In some cases the heat carrier may be introduced into the chamber in molten droplet form, the droplets solidifying before they reach the bottom of the chamber and come into contact with the sprayed liquid.  Baffles may be provided in the evaporation chamber to interrupt the free drop of the heat carrier and thus increase its residence time in the chamber.
