IPC: C07C45/50
Filed: 1955-01-04
Abstract: In the conversion of olefinic compounds having n carbon atoms in the molecule to primary alcohols having 2n + 2 carbon atoms in the molecule, the olefinic compound is passed, together with hydrogen, carbon monoxide, a cobalt carbonylation catalyst and a zinciferous reaction modifier, into a carbonylation zone in which carbonylation temperatures and pressures (e.g. 230-375 DEG  F. and 1500-4500 p.s.i.g.) are maintained, and the aldehyde product withdrawn from said zone is hydrogenated without the intermediate heat-soaking step of the parent Specification, but preferably after removal of metalliferous components.  The reaction modifier, which is preferably employed in an amount of 0.05-0.5 per cent by weight based on the olefinic compound, may be a zinc salt and may be water-soluble or oil-soluble, and in the latter case may be dissolved in the olefinic compound.  The carbonylation catalyst is advantageously cobalt oleate, preferably in an amount equivalent to 0.2-0.5 per cent by weight of cobalt based on the olefinic compound, or cobalt acetate. A suitable arrangement of apparatus is described with the aid of a drawing.  Examples illustrate the application of the process to the conversion of heptenes to primary isohexadecyl alcohols, using as reaction modifiers mossy zinc, granulated zinc, zinc acetate, zinc oxide and zinc oleate.  Also specified are zinc hydroxides, zinc carbonates and the zinc salt of cobalt hydrocarbonyl.

Title: Improvements in and relating to the heat-treatment of metals
IPC: C09D11/00
Filed: 1958-01-03
Abstract: A method of heat treating a ferrous metal workpiece, normally non-austenitic at room temperature, comprises heating and cooling the workpiece at such a rate that austenite is retained at least at the surface of the workpiece.  The rapid heating may be accomplished by producing friction by rapid relative movement between the workpiece and a tool, e.g. a rapidly rotating steel disc having a smooth, ground polished or honed surface.  The quenching may be by dissipation of heat from the small area treated to the remainder of the workpiece and may be assisted by a current of air entrained by the wheel.  The treated workpiece may be subjected to stress, e.g. mechanical shock, to provide a hardened surface.  Specification 884,447 is referred to.

Title: Improvements in or relating to high frequency resistances
IPC: G01R21/00
Filed: 1942-01-09
Abstract: 554,630. Resistances; power measurements. MULLARD RADIO VALVE CO., Ltd., and LATIMER, K. E. Jan. 9, 1942, No. 380. [Class 37] A resistor is so constructed as to have a constant value, apart from skin effects, up to a frequency such that the wave-length may be considerably shorter than the dimensions of the resistor. The resistor shown comprises a cylindrical core 10 of dielectric material such as porcelain, glass, ceramic material, polystyrene &c. On the surface of the core is a resistance element 11 consisting of a coating of resistance material such as a sprayed or adhesively-bonded coating of carbon, or a metal coating of tungsten, platinum applied by sublimation, sputtering, or sintering, or of coppernickel alloy produced by electrodepositing copper and nickel separately and heating to a temperature below the melting point of the alloy or its constituents. Electrical connection with the ends of the resistance element 11 is effected by bands 12, 13 consisting of a coating of silver or other low resistance metal. Surrounding the resistance element is a metal sleeve 14 in the shape of a logarithmic horn. This sleeve is of brass which is electrolytically silver plated and rhodium flashed. The sleeve itself may form part of the resistance element, in which case it may consist of a thin shell of metal or a moulded matrix of carbon suspended in a binder. The throat of the sleeve is soldered or brazed to the terminal band 13, external connections being made to the band 12 and the flared end of the sleeve 14. For connection to a concentric transmission line the dimensions of the sleeve 14 and the element 10, 11 are so chosen that the connecting portions coincide with the outer and inner conductor. High-frequency power may be measured by the temperature produced in the resistance element, as by filling the tube 10 with a fluid such as monostyrene or benzine and measuring its thermal expansion by a pressure-measuring instrument calibrated in watts. Alternatively a thermocouple may be positioned within the resistance element and connected to a voltmeter calibrated in watts. Instead of a coated core the resistance element may be formed of a number of thin wires braided together.

Abstract: 1,078,363. Road traffic signals on vehicles. SWF - SPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU G.m.b.H. Jan. 5, 1965 [Feb. 14, 1964], No. 434/65. Heading G4Q. A vehicle signalling system adapted to supply direction indicating lights 4 and 5 and to give warning signals (flare operation) using one or more existing pairs of lights, is characterized in that a common flasher unit is used for both signals and that the flare switch 2 is connected between the flasher 1 and the turn indicator switch 3. In Fig. 1 the output of the flasher normally passes via contacts 12 and 13 to the switch 3 and lights 4 or 5. The brake lights 7 and 8 are connected to respective contacts 23 and 22 of brake switch 6. When switch 2 is operated terminal 26 is connected to terminal 13 to supply one output from the flasher 1 to brake light 8, and terminal 12 is connected to terminal 23 to connect another output from the flasher to brake light 7. In a modification, Fig. 2 (not shown), the brake switch has a single contact and energizes a relay which energizes the lamps. The warning system may be made operable by switch means responsive to the ignition, the hand brake, or the speedometer, so that it can be used only when the vehicle is stationary.

Title: Rebound dampening devices for printing hammers
IPC: B41J9/42
Filed: 1952-01-07
Abstract: 706,877. Typewriters &c. NATIONAL CASH REGISTER CO. Jan. 7, 1952 [Jan. 12, 1951], No. 445/52. Class 100 (4) Hammer-impression arrangements.-The rebound of a printing hammer is prevented by absorbing the return energy by the displacement of one or more elements, e.g. cam plate 70, Fig. 1, or balls 86, Fig. 5, disposed within a bracket 72 or a chamber 87, respectively. The cam plate 70 is pivotally mounted on a stud 71 in the bracket 72 and has a stud 73 projecting into an aperture 74. When a cam edge 76 on the hammer engages the cam plate 70 the energy is absorbed by a weighted end 75 until the stud 73 strikes the side of the aperture 74. In a modifi - cation, a further surface pivoted on the cam 70 is first engaged by the hammer and pushed against a spring until this further surface engages the cam 70 which then functions as before. In the embodiment shown in Fig. 5, the hammer energy is absorbed by a series of balls 86 which are pushed up the sloping sides 89 of the chamber 87. The hammer is actuated three times in each cycle or revolution of a shaft 49, by the studs 47 engaging a three-armed lever 37. The right arm 39 of this lever has a stud 40 which engages a finger 41 of a pawl 24 and pivots it counterclockwise as the studs 47 engage and pivot the lever 37. A pin. 22 on a hammer arm 17 is thus unlatched from a notch 23 on the pawl 24 and is drawn into contact with a ledge 38 of the arm 39 by a spring 30. When the nose 46 passes each stud 47, a spring 50 drives the arm 39 counterclockwise and ledge 38 effects an impression stroke to the hammer through the pin 22. The movement of the arm 39 is limited by a lower arm 36 of the three arm lever 37 engaging a resilient adjustable stop assembly 34, 53, 54, 55, and the hammer completes its stroke by momentum. The hammer drops back to its normal position and the pawl 24 having been released by the stud 40 and pivoted by a spring 26, re-engages the stud 22 to prevent the hammer rebounding and causing a second impression. With the rapid repeated impressions in each cycle the rebound, without the energy absorbing devices described would be too rapid for the pawl 24 to prevent a second hammer stroke.

Title: Improved means for measuring the weight flow of materials in spouts or ducts
Inventor: HEAUME FRANCIS HERBERT DU
IPC: G01G19/00
Filed: 1952-01-07
Abstract: 700,959. Measuring weight flow. 'SIMON, Ltd., H. Dec. 29, 1952 [Jan. 7, 1952], No. 455/52. Class 143 [Also in Group XXIX] The weight flow of fluid material passing down a shoot a, Fig. 1, is measured by actuating a valve c to divert the flow into a by-pass shoot b containing a weighing device the valve c automatically reverting after a predetermined time so that the weight flow can be calculated. The diversion may be made manually as desired, or at regular intervals by a suitable operating mechanism. Valve operation. The valve shutter c is moved from the position in Fig. 2 to that in Fig. 4 by rotating in an anti-clockwise direction a handle 19 Fig. 2 which is loose on shaft s, Fig. 5; the handle 19 carries with it plate 21 which rotates about shaft s against the action of a spring 22 attached at 18 to a cam plate t, Fig. 5, which is keyed to shaft s and is held against rotation by a detent 15; the valve shutter c is also keyed to shafts. The rotation of plate 21 pulls down arm 27 to pull down rod 12, Fig. 5, against the action of a spring 13 until a stud 30 on plate 21 impinges on 29 to displace the arm 27 so that a pin 25 on plate 21 engages the straight portion of a slot 26 in arm 27, so that the rod 12 is free to move up under the action of spring 13 and an escapement clock-work mechanism 14. At the termination of the rotation of plate 21, a projection 17 thereon displaces the detent 15, Fig. 5, releasing the cam plate t so that it quickly follows the plate 21 under the action of spring 22 and moves the valve shutter from the position shown in Fig. 5 to that of Fig. 4. The rod 12, Fig. 5, now moves upward until after a time determined by the clockwork 14, a collar 11 engages lever 10 to release catch plate w so that spring 23 returns arm 21 to its position in Fig. 2. carrying with it pin 18 on plate t and so quickly returning the shutter c to its Fig. 5 position. Spring balance. The weighing device comprises a bucket d, Fig. 2, suspended by springs e; a pin m on the bucket engages a slot in a quadrant rack n carrying a pointer p moving over a dial. A reference pointer r can be set to any desired position. The bottom of the bucket can be opened by a handle j.
