Title: Process for the hardening of rail heads
IPC: C21D9/04
Filed: 1952-10-23
Abstract: A process of hardening the heads of railway rails comprises cooling and examining the rails coming from the rolling mills, selecting rails having no surface defects, heating a layer on the surface of the heads to a hardening temperature and quenching, and finally heating the rail foot to a temperature sufficient to provide heat to temper the quenched layer, the temperature and duration of heating the rail foot being such that the finished rail-heads are straight or convex when viewed from the side.  The rails may be preheated to 400-500 DEG  C. before heating to the hardening temperature, and the rail foot may be heated to 375 DEG C. for 4 minutes for tempering.

Abstract: 1439341 Handling packages L SOLTANOFF 7 June 1973 27180/73 Heading A4T [Also in Division B8] A method of package identification and handling, e.g. for luggage, comprises training a belt 28 around the package (60), Fig. 3 (not shown), and joining portions 28a, 28b of it together to form a tight loop, at least one portion of the belt having a destination identification 82 on it which may be read subsequently in order that the package (60) may be moved to the respective destination. Belts of heat shrinkable material may be applied at a station 10, the portion 28a being attached to a pressure-sensitive adhesive layer 40 on a sheet 36 fixed to the end 28b. The packages (60) are then fed through an oven 12, where shrinkage of the belts 28 causes them to become tight, and they may proceed directly to a reading station 14 in advance of exit conveyors 21-24, e.g. for transporting baggage to an appropriate aeroplane. At the station 14, the packages (60), are fed on two series of rollers 92 at least one series being driven, and optical scanners 90 read the code represented by the bars 82 on the belt 28, the scanners 90 being directed at different regions of the belt 28 in case any region should be distorted. A lamp 130 and photo-detector 132 monitor the packages (60) leaving the station 14 so that any package (60) leaving without having been correctly read may be directed into an error exit, an alarm also being sounded. The bars 82 preferably run longitudinally of the belt 28, but groups of transverse bars may be provided, Fig. 8 (not shown).

Title: Improvements in or relating to speed limiting apparatus for lifts and hoisting gears
IPC: B66D5/04
Filed: 1964-07-02
Abstract: 1,042,553. Overspeed-prevention devices for lifts. INVENTIO A.G. July 2, 1964 [July 30, 1963], No. 27282/64. Heading B8L. [Also in Division F2] A speed limiting device for lifts and hoists consists of a braking arrangement including a rotating carrier, e.g. in the form of a pulley wheel 2, which is connected by a cable 3 to the lift cage or a stopping device on it, at least one centrifugal body pivoted on the carrier for outward movement into contact with a stationary drum 1.3 against the force of a spring, when a predetermined speed is exceeded, and a stop limiting inward movement of the body, the body being arranged to pivot during such outward movement, whereby the spring is adapted to go over-centre and thus exert a reverse torque on the body on contact of the latter with the drum, which maintains such contact. The body preferably has a self-wrapping effect upon contact with the drum so that the carrier is locked to the drum. In the embodiment shown, four bodies 6, 7, 8 and 9 are pivoted on the carrier, two being arranged to lock the carrier in each direction of rotation. Each such pair of bodies are linked by a respective loosely mounted ring 24, 25 on a shaft 4, by which the pulley 2 is journalled in the casing 1.2 of the stationary drum 1.3, each ring being connected to the associated bodies by links 20, 21 and 22, 23 respectively. Adjustable stops 6.2, 7.2, 8.2, 9.2 engage abutments 10, 11 secured to the carrier to fix the inner positions of the bodies. Springs 12, 13, 14, 15 normally keep the bodies against the stops and their lines of action are arranged to pass through the positions of the body pivots prior to engagement of the bodies with the drum, i.e. pass " over-centre " and thus cause the carrier to be permanently locked once the predetermined speed has been exceeded. In a modification (Figs. 4 and 5, not shown), employing only two bodies 40, 41 which lock the carrier in one direction of rotation corresponding to downward movement of the lift cage, a re-setting arrangement for the bodies is provided comprising a knob 49 adapted to be manually rotated to act via a transverse pin 50 and slots in ring 46 which interconnects the bodies, so that the bodies can be brought back, after outward locking movement, into contact with abutments 42, 43 on the carrier 34. Also, in this embodiment, the pulley wheel 36 is separate from the carrier and coupled with it through a slipping clutch.

IPC: C07F7/24
Filed: 1927-10-14
Abstract: 283,913. Daudt, H. W. Jan. 20, 1927. [Convention date]. Lead tetra-alkyls are obtained in one' operation by the reaction of magnesium, an alkyl halide and a lead salt. In an example, a suspension of lead chloride and magnesium turnings in dry ether is placed in a vessel provided with a reflux condenser, and ethyl bromide is added. The temperature is gradually raised to 30-35‹ C. When the reaction has started it may be necessary to apply cooling. More ethyl bromide is added and the temperature is maintained at boiling point (35-39‹ C.) for 12 hours after all the ethyl bromide has been added. The mass is then, drowned in water and enough caustic soda is added to give a red colour to Brilliant yellow paper. The ether is distilled off at a low temperature and them the lead tetra-ethyl is distilled off in steam. Instead of alkyl bromide there may be used another alkyl halide such as iodide or chloride but when chloride is used it is usually necessary to add a catalyst such as methyl iodide and iodine. Instead of lead chloride another lead salt mav be used. A diluent such as gasoline, benzene, or toluene may be added.

A friction clutch of the plate or disc type in which the clutch is engaged by interposing between a fixed collar a and an annular plate b, which applies pressure to a presser plate c for pressing the plates or discs together, a ball race d having a number of cylindrical slots e extending therethrough at equal distances round the race and parallel with its axis. A radial cylindrical slot f breaks into each axial slot at a midpoint, and three hardened steel balls g fit each radial and axial slot. The ball in the radial slot bears upon and between the other two balls in the axial slot. A sleeve h, having an internal conical portion for pressing the balls further into the radial slots causes the balls in the axial slots to protrude and so exert closing pressure between the clutch plates or discs.

A spring loaded and headed plunger m is located in the annular plate b and is adapted to enter any one of a series of holes in the presser plate. A pin extends through members a, d, b, so that they turn together. To adjust for wear a key is adapted to be passed into a peripheral hole p in the annular plate and, when turned, moves plunger m clear of the presser plate, so that the key can be used to turn b, d and a upon an internal sleeve q until the plunger m aligns itself with the next hole in the presser plate.
