Title: Improvements in rail vehicles
IPC: B61F5/18
Filed: 1956-06-11
Abstract: 807,135. Mounting bodies on railvay vehicles. MASCHINENFABRIK AUGSBURG-NURNBERG A. G. June 11, 1956 [July 7, 1955], No. 17929/56. Class 103(6) A rail vehicle body is supported at each end by a two-part spring cradle on a bogie guided by a pivot pin of the vehicle body, an upper part of the cradle being supported at both ends, by vertically compressible cradle springs, on a lower part of the cradle, the arrangement being such that longitudinal forces are transmitted directly between the vehicle body and bogie and transverse forces are transmitted initially by way of the cradle and thereafter directly between the vehicle body and bogie frame. In the construction shown the vehicle body 2 is supported by rollers 39, 40 on a cradle 3 comprising a pair of upper spring troughs 8, 9 and a pair of lower spring troughs 10, 11 with intervening helical springs 6, 7, the lower troughs being suspended by swing arms 33 from a bogie frame 1. The troughs 8, 9 are connected together pivotally by a link assembly 4 consisting of two tubular members 17, 18 united in a single bearing 23 adjacent the trough 8 and braced by a tubular member 21 adjacent the trough 9. The troughs 10, 11 are similarly connected together by a link assembly 5 consisting of tubular members oppositely united and braced relatively to the sides of the vehicle. The vehicle body is pivoted with a pivot pin having bracing ribs 41 and tubular segments 42 43 with wearing plates 44, which bear against pressure pieces 46 these pieces are connnected to a stiffening sheet 48 held between the tubular members 17, 18. The pivot pin at the bottom is provided with an elastic bush 49' and a crowned bush 50 located in a guide tube 51. The guide tube is supported in a crosshead 52 held at its ends by links 53, 54 which are attached to the bogie frame 1. The guide tube extends through and guides the link assembly 5. The pivot pin has transverse movement relatively to the bogie frame 1, there being a space S between the segments 42 and resilient stops 55. Transverse forces on the vehicle body are not directly transmitted to the bogie frame until the space S between a segment 42 and a stop has been closed.

Abstract: 552,879. Partial esters. ATLAS POWDER CO. Dec. 21, 1940, No. 17985. Convention date, Dec. 21, 1939. [Class 2 (iii)] [Also in Group VI] Water dispersible partial esters are prepared from a hexitol or inner ether thereof and lauric acid, coconut oil or mixed fatty acids of coconut oil. Substances other than the partial esters are formed which serve to confer water dispersible properties on the hexitol-lauric acid ester. A composition of the kind stated may be obtained by reacting mannitol with lauric acid or mannitol with coconut oil in the presence of an alkaline catalyst e.g. Na OH or Na 2  CO 3  at 200‹-300‹C. Sorbitol is also mentioned.
Patent GB-386665-A (GB)
Title: Improvements in the manufacture of hardened iron and steel alloy articles
IPC: C23C8/02
Filed: 1931-06-22
Abstract: In the manufacture of hardened iron or steel alloy articles, the article is roughly fabricated from alloys containing a nitrogenizing element such as aluminium, chromium, molybdenum or manganese and a precipitation-hardening element such as copper, beryllium boron or titanium is cooled from a temperature lying between the nitrogenizing temperature and 1300 DEG  C. in water, oil or air, is fabricated or worked to its final shape and then subjected to the usual nitrogenization process which also produces precipitation hardening. The articles may be tempered at a temperature below the critical temperature but above the nitrogenizing temperature before it is fabricated or worked.  In a modification, the article is produced by working, is then nitrogenized, cooled quickly from the nitrogenizing or a somewhat lower temperature and then hardened by tempering a temperature below that of nitrogenizing or allowed to age at room temperature. Alloys are referred to containing specified quantities carbon, aluminium, manganese, chromium, silicon, molybdenum, copper, boron, and nitrogen.

Title: Improvements in and connected with lock-nuts and the like
IPC: F16B39/32
Filed: 1920-07-02
Abstract: 160,706. Mansell, W. H. July 2, 1920. Locking nuts.-A nut-lock of the ratchet type comprises a plunger B to which is pivoted a disc E, the plunger being located in a bore A in the nut &c. opening into the threads. The disc is adapted to bind between the wall of the bore and the bolt &c. upon reverse rotation, and is maintained in position by a spring C interposed between the bore wall and the plunger head or between the end of the bore and the end of the plunger. The plunger projects beyond the end of the bore so that when a spanner is applied to the nut the plunger is forced inwards bringing the disc out of engagement with the bolt and permitting reverse rotation. If desired, two locking devices may be applied to a nut so as to prevent rotation in both directions. Specification 141,936 is referred to.
Patent GB-1016192-A (GB)
Title: Polymerization process
IPC: C08F210/18
Filed: 1963-05-08
Abstract: A process for the continuous copolymerization of ethylene with at least one olefinic compound to produce a copolymer containing between 10 and 90 mole per cent ethylene, in a system in which the relative rates of polymerization of ethylene and the olefinic compound differ by a factor of at least 2, comprises continuously feeding to a reaction zone containing a rapidly agitated reaction mixture having turbulent randomly directed flow, a feed stream comprising the monomers and a catalyst, and continuously withdrawing at the same rate from the reaction zone a liquid product stream so as to maintain a constant volume of liquid in the reaction zone and to establish steady state conditions and a residence time of predetermined duration.  The copolymerization is preferably effected both in the presence of hydrogen and in the presence of an organic liquid which is a solvent both for the monomers and for the copolymer produced. Many such solvents are specified of which hexane is exemplified. Comonomers exemplified are propylene, butene-1 and dicyclopentadiene; many others are specified including pentene-1, butadiene, isoprene and 2,3 dimethyl butadiene. The catalyst system, which must be soluble in hydrocarbons, comprises a transition metal compound and an organo-metallic reducing agent which are introduced into the reaction zone in separate feeds.  Long lists of suitable catalyst components are given; those exemplified are vanadyl chloride; tri-n, sec- and tertbutyl vanadates, aluminium diethyl chloride and aluminium ethyl dichloride.  The product stream is flowed into ethanol to precipitate the copolymer which is then refluxed with methanol. The copolymers produced are amorphous and rubber like, and are completely free from crystallinity as determined by X-ray measurements. The copolymers may be vulcanized with conventional vulcanizers and accelarators.

During movement of a pin carriage 39 a guide arm 14 with a setting lever 13, with an abutment and a pin 12, pivoted thereto at 15 limits the deflection of the setting lever 13 according to the position of the pin carriage 39 such that the returning force on the pin carriage 39 from a cam 2 on the main shaft 1 rocking a draw lever 4 is proportional to the distance moved. The setting lever 13 pivots with the draw lever 4 until the abutment registers with a shaft 19 and then pivots on the guide arm 14 with a pin 12 registering in a recess on the draw lever 4. A pin 21 on the guide arm 14 cooperates with a draw hook 23 with a hooked end 28 which engages a pin 31 such that when the draw lever 4 returns to its initial position a bellcrank 30 and link 34 return the pin carriage 39.
