Title: Improvements in the treatment of montan wax
IPC: C10G73/00
Filed: 1927-06-09
Abstract: 296,145. Johnson, J. Y., (I. G. Farben. industrie Akt.-Ges.). June 9, 1927. Mineral waxes.-Montan wax which has been bleached by oxidizing agents, e.g. chlorine, chromic acid, or air and nitric acid, is treated to convert the. free organic acids completely or in part into metal salts, esters, anhydrides, amides or their substitution products, ketones, or other substances containing the groups -CO- but not the group -COOH. The wax thus produced does not crystallize, and is especially suited for use in leather and floor polishes. Ethyl alcohol, ethylene or butylene glycol, glycerol, butanol, or mixtures thereof are specified for esterification, zinc hydrate, alkalies, alkaline earths, or mixtures thereof for forming salts. The acids may be in part esterified, and in part formed into salts. Or montan wax, the free fatty acids of which have been esterified, &c., may be melted with wax in which .the free fatty acids have been otherwise modified. For example, a wax with excellent polishing properties is obtained by mixing a calcium-zinc-glycerolester wax with a calcium-amyl-ester wax. In examples, 100 lb. of wax bleached with chromic acid is treated at 110-120‹ C. with a solution of 2 lb. of sodium carbonate or caustic potash in 5 1b. of water, or a 200‹ C. in an autoclave with 25 lb. of glycerol or with gaseous ammonia or at 140‹ C. with 8 1b, of glycol and then at 130-140‹ C. with 2 1b. of calcium nydrate.

Abstract: 779,658. Sonic and ultrasonic pulse-echo systems. BRITISH THOMSON-HOUSTON CO., Ltd. May 19, 1955 [May 25, 1954], No. 15435/54. Class 118 (2). In order to prevent collisions between a moving object travelling along a fixed path, e.g. a travelling crane, and an obstacle, e.g. a building or another crane travelling on the same support rails, a directional sonic or ultrasonic pulse echo sounder is mounted on the moving object or on the obstacle and the echo pulses are applied to a relay through a gate circuit such that the relay is operated only when the moving object is within a predetermined dangerous distance, e.g. 20-30 pt. from the obstacle. The relay may control an aural or visual alarm and/or operate control apparatus which slows down or stops the moving object; the alarm and stop devices may be controlled by separate receivers gated on for different periods.

IPC: C01B32/336
Filed: 1927-06-09
Abstract: 298,546. Schober, O. June 9, 1927. Carbonizing apparatus for use in the production of active charcoal comprises a rotary I retort c fed with coal, peat, or coke from a container a through a heat-exchanger b. Activating gases enter through an opening e, and the product passes through a cooling chamber d to a collecting chamber d'.

Title: A method of producing acid bessemer steel or thomas steel low in nitrogen
IPC: C21C5/28
Filed: 1945-06-19
Abstract: An oxidising agent, e.g. iron ore, soda, scale, is added to a Bessemer converter, before the end of the blow to obtain denitration, the supply of the air blast or of an air blast-gas mixture, being arranged so that it passes only through part of the melt.  To effect a partial blowing through a side-blown converter it is tilted so that the larger part of the melt lies on the converter side, and only a short depth is in contact with the converter bottom and thus is penetrated by the blast.  It may also be carried out by admitting the blast through part of the bottom or through the side wall of an erect converter.  With some oxidising agents additional blast is required and can be added above or below the level of the bath.

Tangential springs 3, transmitting torque between a member 1 and arms 8 on a member 7, are equally circumferentially spaced as by being housed through sliding end caps 4, in pockets 10 in the member 1, the caps 4 being provided with flat surfaces 17 bearing with freedom for axial and radial relative movement on flat surfaces 16 of the arms, and one of each of the pairs of surfaces (as shown, the surfaces 16) being formed on balls 13 universally mounted in the corresponding caps or arms. As shown, the invention is applied to a rail vehicle individual axle drive, the member 1 being a gear journalled in the locomotive frame and driven by a pinion from an electric motor, and the member 7 being keyed to the driven axle 6. The balls 13 are received in split spherical bushes 11 press-fitted into cylindrical bores in the arms 8, and are retained therein by further spherical surfaces 27 on the bushes 11 engaging offset spherical surfaces 26 on the balls. Springs 25 hold the balls frictionally against the surfaces 27 when the surfaces 16, 17 are out of contact, to retain the balls in correct alignment. In Fig. 3 (not shown) the springs and surfaces 26, 27 are dispensed with, the balls being retained simply by extending their normal surface of spherical contact over more than half their total area, and their out-of-contact alignment being maintained by designing them so that their centre of gravity coincides with their geometrical centre.

Title: Envelope stuffing machine

Filed: 1974-04-10
Abstract: 1448938 Clutch-brake combinations MATHIAS BAUERLE GmbH 10 April 1974 [26 April 1973] 15872/74 Heading F2L [Also in Division B8] In an envelope stuffing device (see Heading B8C), fingers 24 for opening the envelopes are driven in a closed curved path comprising two distinct parts by an intermittently actuated eccentric shaft 31, 32. One end of the shaft loosely carries a gear 36 permanently engaged by a continuously rotating drive gear 40. The gear 36 is located between a ring 37 and a bushing 38 both of which are fixed to and rotatable with the shaft and the latter of which is urged by a spring 39 into frictional engagement with gear 36. The bushing carries a pair of axially spaced cam discs 41 and 42 provided with stop cams 43 and 44 respectively which cams are spaced apart by 270 degrees. The stop cams are engageable by one or the other of stop projections 45, 46 located on the forked arms of a lever 49, 54 pivotable about the shaft 50 on which the drive gear is mounted. Normally the upper end of the lever is biased towards the left as viewed in Fig. 2 by a spring 51 but this can be overcome by a solenoid operated arm 53 connected to the lower end of the lever. In use, in the position of Fig. 2, rotation of the bushing and thus the shaft is prevented by stop projection 45, slippage occurring between the bushing and the gear 36. When it is desired to actuate the fingers 24, the solenoid 52 is actuated to move projection 45 to release the bushing for a 270 degree frictional rotation by the gear 36 until projection 46 engages stop cam 44. When further movement of the fingers back to their original position is desired, the solenoid is deactuated to withdraw the projection 46 to allow a further 90 degrees rotation of the bushing back to the position shown in Fig. 2 in which position it is once more halted by the stop projection 45.
