Abstract: 932,931. Stapling-machines. BOSTITCH Inc. March 27, 1962 [June 21, 1961], No. 11596/62. Class 89 (3). A stapling tool 20 comprises a driving mechanism, a guide bar 50 for the staples moved by a pusher 52 connected to a tensioning device, the latter comprising a manual controller 58, slidable in slots 62, the ends 80 of the slots being turned to provide a forward operating position and a rearward loading position for the manual controller, guide means 70, 72 being provided adjacent each end of the guide bar, a coiled spring 68 passing around the guide means, the spring having one end secured to the manual controller and the other end secured to the pusher. The slots 62 are formed in side walls of a base 26 to which the guide bar 50 is secured, a pin 60 of the manual controller sliding in the slots; knobs 64, 66 are mounted on the pin. As shown in Fig. 1, the stapling tool is loaded with staples 76, the controller being in its forward position and the spring 68 being tensioned around guide rollers 70, 72. To reload the tool, the manual controller is disengaged from the end 70 of the slot and moved rearwardly, the pin then engaging with a hook 54 formed on the pusher and thereby lifting the latter to a position shown in Fig. 5; new staples 76 can then be easily mounted on the guide bar 50. The stapler is operated by compressed air acting on a spring-loaded piston 28.

Patent GB-650984-A (GB)
Title: Manufacture of isocinchomeronic acid
Filed: 1948-04-28
Abstract: Isocinchomeromeronic acid is manufactured by oxidizing a 2 : 5-dialkylpyridine with nitrogen tetroxide (preferably in the presence of a solvent) or with nitric acid of 15-95 per cent concentration, at an elevated temperature and superatmospheric pressure and precipitating and filtering isocinchomeronic acid from the acid mixture.  When using nitric acid, the preferred concentration is 40-65 per cent and the net ratio of HNO3 to dialkylpyridine should be between 3 : 1 and 15 : 1, preferably about 6 : 1.  Suitable reaction conditions are a temperature between 75 DEG  and 200 DEG  C. (preferably 160-190 DEG  C.), and a pressure between 30 and 700 lbs. per square inch (gauge).  An oxidation catalyst (e.g. ammonium vanadate or vanadium pentoxide) may be present, and air or other oxygen-containing gas may be passed through the reaction mixture.  At the end of the reaction the liquid product obtained may be diluted with water (e.g. 4-5 times its volume) to precipitate the greater part of the isocinchomeronic acid.  The remainder may be precipitated as its copper salt, or the liquid containing it and the excess of nitric acid may be recycled after adding fresh nitric acid.  Examples describe the oxidation of 5-ethyl-2-methylpyridine with various concentrations and proportions of nitric acid.  2 : 5-Dimethylpyridine is also specified as a starting material.

Patent GB-690875-A (GB)
Title: Method of stabilising against shrinkage textile materials predominantly of regenerated cellulose
IPC: D06M15/423
Filed: 1950-05-12
Abstract: The tendency of textile materials consisting wholly or mainly of regenerated cellulose to shrink or pull out is prevented by impregnating the materials with an aqueous medium having a pH of 1.2 to 6.5 and containing a water-insoluble, alkali-soluble cellulose ether, e.g. hydroxyethyl cellulose, a water-soluble substance, e.g. formaldehyde, glyoxal or a melamine-formaldehyde precondensate or the constituents thereof, which is convertible by heat under acidic conditions to an insoluble resinous condition, a strong mineral acid and an alkali metal salt of the mineral acid, removing excess medium, drying and then heating the impregnated material.  The aqueous medium is prepared by mixing the cellulose ether and the heat-convertible substance with an aqueous solution of sodium, potassium or lithium hydroxide and then adding the mineral acid, e.g. sulphuric acid. Impregnation, drying and heating may be effected with the materials under tension, drying being preferably effected at 200-240 DEG  F., and heating at 300-350 DEG  F., the latter operation being preferably effected by blowing with hot air.  The drying and heating operations are effected in the absence of pressure.  To the aqueous medium plasticizers, e.g. ethylene glycol monobutyl ether, the partial esters of sorbitol, mannitol, glycerol or glycol with stearic, oleic, myristic or lauric acid or a mixture of sorbitan monopalmitate and sorbitan tristearate which has been condensed with ethylene oxide, may be added.

Title: Apparatus for recovering heat from coke, slags, ashes and other solid substances
IPC: F22B1/04
Filed: 1924-05-15
Abstract: 228,406. Bringhenti, P. May 15, 1924. Heating by hot solids.-The heat contained in hot coke, slag, ashes, &c., is recovered by quenching the material in water in a boiler, and subsequently vaporizing the water in another chamber. The hot material passes from a charging hopper T to a heat-insulated receptacle R and thence to a boiler C. The material is removed from the boiler by a conveyer A to a bucket elevator E of sufficient height to balance the pressure of the steam generated. Some of the water is forced through a pipe B to a vessel V where it is partly vaporized, and the steam is drawn off through a pipe D. The water is returned to the boiler by a centrifugal pump P. Gas accumulating in the boiler is drawn off through the pipe G and passes into the boiler feedwater, where any steam is condensed. Any salts present in the hot slag &c., are recovered from the water in the boiler.

Title: Manufacture of concrete and the like pipes
IPC: B28B21/26
Filed: 1950-05-16
Abstract: 667,845. Moulding pipes from concrete &c. FEJMERT. E. V. May 16,1950. No. 12156/50. Class 87(ii). Apparatus for making concrete pipes comprises a vertical cylindrical mould 11 with a closed lower end and coaxial core 12 in it, a downwardly-biassed verticallymovable member 40 extending into the space 39 between the mould and the core and carrying helical blades 44 at its lower end, and means for rotating the mould in the direction (relatively to the hand of the helical blades) such that the blades, pressing on the material, will be raised thereby against the bias applied to the vertically-movable member as long as the material is being fed to the space. A sleeve 20, rotatable on bearings 21, is chaindriven from a motor 25 and transmits its motion through pins 17 and a base plate 15 on which the mould is detachably mounted. The core 12 has a conical spigot 27 by which it is normally supported and has an upwardly-extending shaft 28 by means of which it may be withdrawn from the mould, this withdrawal being effected by a winch and cable 33, 34. Rotation of the core is prevented by a cross-head 30 guided in frame members 31. Raising the core also raises the cylindrical member 40, which shrouds it and is likewise prevented from rotation by having a sleeve 41 with a cross-head 43 guided in the frame members 31. When the core and member 40 are raised the feed table 38 can be lifted from its stop 54, when a catch 53 is released, and swung on a hinge 55 to give full access to the mould. When the core and member 40 are lowered in their working position and the mould is rotating in the appropriate direction, as the concrete is delivered into and falls to the bottom of the space 39 it is caused to rotate by contact with the mould and, passing under the helical blades 44, reacts against their under surface, thus raising the blades and the member 40.and thereby pressing down the concrete in the space 39 towards the bottom of the mould. As the mould rotates in this direction it is vibrated as the result of a toothed ring 47, beneath the base plate 15, running over another toothed ring 48 which is held fast to a table 49 by a pawl. Rotation of the mould in the opposite direction however causes the rings 47, 48 to rotate together. Alternatively, use can be made of an independent vibratory device, .e.g., 56, preferably electrically driven and acting on the mould through the spring- mounted table 49.

Abstract: 198,874. Newbon, H. A. May 1, 1922. Targets; projectiles. -A projectile is made of flannelette, felt or other clinging material and has a superficial area greater than that of a pad of clinging material on a carrier projectile to which it clings during transit. The target used is made of flannelette or other similar clinging material so that the projectile adheres to it on impact, indicating the spot at which the target was hit. The clinging material may be treated with a gelatinous, mucilaginous or starchy agent to increase its faculty for clinging. After applying starch the material is ironed. As shown in Fig. 1, the projectile a is pressed on to a pad b which is secured by glueing or pinning to a cork c, into which fits a rod d. A cushion of rubber may be placed between the pad b and the rod d.
