Abstract: 175,400. Napier & Son, Ltd., D., and Rowledge, A. J. Nov. 15, 1920. Actuated or applied by running axle; forcetransmitting mechanism.-The brakes of motor vehicles are arranged to be actuated by a shaft through which the drive is transmitted to the road wheels by means of a friction clutch which turns a cam engaging a lever connected to the brakes. The sleeve B splined on the end of the driven shaft A and having the usual universal joint member B<1> for connection with the Cardan shaft is provided with a flange B<2> carrying an annular member C forming one member of the clutch. A second clutch member D is mounted to rotate with the member C and to have axial movement relative thereto. Between the clutch members C, D is disposed the driven clutch member H<3> secured to a sleeve H freely mounted on the fixed sleeve F. The sleeve H is provided with a pair of oppositely inclined cam-surfaces J engaging a roller K on a lever K<1> connected to the brakes by a link K<4>, lever L, L<2>, and rod L'. The cam member H, J is normally centralized in the release position shown by a cable connected at one end thereto and at the other end to a spring or weight. To apply the brake a pressure ring D<1> is actuated by the arms E, rockshaft E<1>, and connections E<2>, E<3>, to force the clutch members C, H<3>, D into contact, thereby turning the sleeve H and engaging one or other of the cam-surfaces J with the lever K<1> according to the direction in which the vehicle is running. The clutch shown may be replaced by a cone clutch. Fig. 5 shows a spiral cam by which a more gradual application of the brakes is effected. The clutch member C may be geared to the shaft A instead of being driven directly thereby. Epicyclic gearing may be employed to drive a concentric shaft carrying the member C, or it may be mounted upon a lay shaft. The clutch members and cam may be mounted in a casing M carried on the after end of the change-speed gear box.

Title: Process and Apparatus for Heating and/or Vaporizing a Stream of a Medium in a Furnace containing at least Two Coils arranged in parallel
Inventor: KOETSIER JAN EDUARD
IPC: C10G9/20
Filed: 1968-07-09
Abstract: 1,173,857. Automatic temperature control systems. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. July 9, 1968, No. 32614/68. Heading G3R. In a process for heating and/or vapourizing a stream of a fluid in a furnace containing at least two coils arranged in parallel, between which coils the fluid is distributed, the rates of flow Sj to the individual coils are adjusted so that the individual temperatures Tj of these flows at the leaving ends of the coils differ as little as possible. From a vessel 1 fluid to be heated passes via a line 2 to a furnace having coils 3-6 in parallel which are heated by a burner 8 regulated by a flowmeter 9 and controller 10, the set value for the latter being derived from a temperature sensor 11 and controller 12 into which the set value of the temperature may be injected. Each coil is provided with a flowmeter 13-16 and controller 17-20 respectively providing constancy of the individual flows. Temperatures Tj are measured at the coil outlets by meters 21-24 signals from which pass to a computing element 29 where the average, Tav, of the four temperatures Tj is calculated, the value Tav constituting the set value for integral action controllers 25-28 and the difference between this and the individual coil temperatures each forms a set value for one of the flow controllers 17-20 if the level of the fluid in column 1 does not change hence the flow to each coil is dependent on the temperature deviation from the average temperature value, and it can be shown that the sum of the flows remains constant. To compensate for variation of fluid level a gauge 30 connected to control 31 passes an output signal to computing elements 32-35 which multiply this signal by individual signals representative of temperature differences from the average giving a resultant value such that increase in fluid level increases the flow through all the coils simultaneously. Correction of drift is compensated by ascertaining the average of the four values Tav-Tj in a computing element 36 the output of which is multiplied with the input Tav to controller 25. The control may be continuous or periodic and may be carried out electrically, mechanically or pueumatically. The calculations may be performed by digital means.

Abstract: 524,922. Making compound pipes. ARMSTRONG, J. J. V. (American Rolling Mill Co.). Nov. 10, 1938, No. 32643. [Classes 83 (ii) and 83 (iv)] [Also in Group XL] Soldering.- Relates to apparatus for making tubing from strip metal stock in which portions of the strip are bent to tubular form and then united by molten sealing metal as they pass through a heating zone, and consists in maintaining heat uniformly over a given length of tubing in a zone and directing light from the tubing, within said length, upon a photo-electric cell in a relay circuit adapted to stop the feed of the tubing through said zone and the heat supply thereto if the temperature of the tubing lies above or below a predetermined range of temperature. The machine shown in Fig. 1 is designed to make a tube of the kind shown in Fig. 4 comprising an inner ply 1 with a butt seam and an outer ply 2 with a scarfed seam. The strip 1 for the inner ply is made into a tube by rollers 3, while the strip 2 for the outer ply has its edges bevelled by rollers 4. The strip 2 is then made into a tube around the tube from the strip 1 by rollers 5, after which the twoply tube passes between three sets of rollers 10, 11, 12. The middle set 11 is connected to a bus-bar 15, and the outer sets to a bus-bar 13 ; and these bus-bars are connected to the secondary of a transformer 14, the primary of which can be connected to a power supply by a switch 60 controlled by a solenoid 61. During the passage of the two-ply tube from rollers 10 to rollers 12 the tube is heated by the electric current which causes a coating of soft or hard solder at the joints to melt. On leaving the rollers 12, the tube is passed by rollers 25 to a cooler 26 where the joints harden. The heating can be regulated by adjusting the rollers 10 in relation to the rollers 11 by means of a handle 23 operating a gear 22 on a screw 20 mounted on a frame 16, and adjusting the relation of the rollers 10 and 11 together in relation to the rollers 12 by a handle 24 operating the screw 20 which besides engaging the gear 22 also engages a lug 21 on the housing of the rollers 11. The tube is enclosed by a series of tubular housings 29, 28, 27, and 27a; and when a jointing material such as copper is used, a reducing or neutral gas is introduced into the housings by a pipe 29a.

An apparatus which dispenses predetermined quantities by weight of viscous liquids e.g. liquid resin, comprises a liquid weigh vessel 16 supported on a beam 15 pivoted on knife edge 14 and balanced when empty by a counterweight 17. In operation when a required quantity of liquid is fed from supply pipe 20 to the vessel 16 the beam tilts and causes a switch 25 to close. Thereby a solenoid valve 23 is actuated to shut off the liquid supply and a valve 26 in a compressed air supply line is actuated so that the air is connected to the vessel 16 which forces the liquid up a discharge pipe 19. As the vessel empties the counterweight 17 restores the beam to its initial position and switch 25 opens thus reopening the liquid supply valve 23 and stopping the air supply to the vessel and the cycle is repeated. A time delay mechanism (not shown) is incorporated to ensure that the vessel is empty before commencement of the new cycle. An alarm bell 27 may be provided in the time delay circuit to give warning of faulty operation and prevent overfilling of the vessel.
