Title: A new or improved machine for making washers or the like
IPC: B21D53/20
Filed: 1939-10-27
Abstract: 533,279. Making washers. GUEST, KEEN & NETTLEFOLDS, Ltd., and CHAPPUIS, J. A. Oct. 27, 1939, No. 28807. Addition to 520,121. [Classes 83 (ii) and 83 (iv)] The machine for making washers from wire according to the parent Specification has modified coiling mechanism, shearing-adjunct, blank transferring means, and ejecting mechanism. Coiling.-The wire 193, Fig. 3 is fed under a grooved guide roller 192, mounted on an arm pivoted at 190 and adjustable at 194, to shunt rollers 205 mounted on brackets radially adjustable at 200, 201, the mounting being pivoted at 203 and adjustable at 206. The wire passes between the flared mouth of a sleeve 158, Fig. 6, and the coned end 175 of a mandrel mounted with lateral float at 181 in a nest 179 that provides axial adjustment. The sleeve is mounted in a spindle 157 having a lining 208 rotatable independently of the spindle that is driven intermittently through pawls and ratchet wheel 163 from a pinion 116 oscillated through one turn, more or less, by a sector 155 linked to a crank 150 on the side shaft 40, the connection with the sector being by a radial slot to permit adjustment of the amount of oscillation. A permanently applied brake 161 prevents reverse rotation of the spindle under the drag of the pawls but permits slight reverse rotation if necessary under the resilience of the coil, that passes from the lining 208 over the nose 210 of a grooved mandrel 209, the end of the coil being engaged by a pivoted stop 230, after somewhat less than a complete turn. The stop is spring controlled and is swung aside by an adjustable abutment 234 on the slide 24 that engages the heel 235 of the stop just prior to the action of the cutter 216. Shearing, adjuncts.-The cutter is carried by a slide actuated by an arm 219 on a rock shaft 214 having a second arm in contact with a plunger 221, Fig. 9 (not shown), traversed by an abutment 222 on the slide 24. A member 228 on a third arm is engaged by the surface 226 for the return stroke of the cutter. Blanks, transferring.-The cut-off ring is received and transferred to the flattening and consolidating dies.by a slide 245, Fig. 7, reciprocated by a link adjustable at 243 from an arm adjustable at 241 on a rock shaft 238 oscillated by a cam attached to or formed on the bevel wheel that drives the cross shaft 40 from the press shaft. The slide has a fixed lower jaw 247, with abutment 248 and serrations 249 extending parallel to the direction of movement, and an upper jaw 253 curved to receive the ring, pivoted at 252 under the influence of a spring plunger 255 and stop 256, and engaging a bevel-ended pin 257 that is engaged by a corresponding shoulder on the flattening and consolidating punch 250 to free the blank for transfer to the die of the punch. Ejectors.-The ejector 124, Fig. 6, is actuated by a stud 268 on a lever 261 pivoted at the upper end instead of the lower end as in the parent Specification, so that any error in the actuating cam due to wear is transmitted to the ejector in diminished instead of augmented amount.

Title: Tool supporting apparatus
IPC: B23Q16/06
Filed: 1966-06-29
Abstract: 1,119,383. Tool posts. A. B. CREED. 29 June, 1966, No. 29134/66. Heading B3T. An indexable tool post comprises a body portion 10 which is mounted for rotation on a spigot 11 which is attachable to a machine tool by a T-bolt 12, the upper portion of the spigot having a threaded portion 23 to engage, when the body and spigot are assembled, a clamping nut 28 with an actuating handle 31 and which in operation clamps the body to the spigot in one of a plurality of positions, the upper surface of the body 10 being recessed to receive a combined ratchet and cam member 41, 42 which co-operates with a pin 35 slidably located in a bore 34 parallel to the axis of the spigot, the lower end 38 of the pin being shaped to engage V-grooves in the conical base surface 25 of the spigot and the upper end of the pin having a roller 37 which engages a ramp surface 45 on the cam ring 43. A cover ring 39 is positioned over the body recess and when the parts are assembled spring-loaded pawls 54 extending from bores 53 on the underside of the nut 28 engage in the ratchet teeth 41. In operation, anticlockwise rotation of the handle and nut 28 unclamps and indexes the body portion 11 carrying the tools 18. Rotation of the nut effects rotation of the ratchet ring by means of the pawls 54 which effect the disengaging of the pin 35 from the spigot 11 by the action of the spring plunger 48 acting on the cam ring surface 47 which at the same time urges the body portion to rotate in advance of the handle 31. The roller 37 of the pin subsequently partially disengages from the ramp 45 so as to permit the end 38 of the pin 35 to engage the conical surface of the spigot until by movement of the body it engages the next slot. Rotation of the handle and nut clockwise clamps the tool body in the new position.

Abstract: 1401424 Grain drying and storage E H BENTALL & CO Ltd 22 June 1972 [22 June 1971] 29328/71 Heading A2Q [Also in Division F4] Grain is stored and ventilated and/or dried in a container 4 provided with perforated air ducts 2 supplied with heated or unheated air, an air supply control unit 18 being connected to two electrical-resistance temperature sensors 14 and 16, and providing the facility for altering the resistive value of the upper sensor 16 and hence the difference in resistance between the sensors 14 and 16. The moisture content of the grain is sensed as this difference. Ambient air is first passed through the grain by means of a low volume fan 8 to homogenize its temperature and moisture content, then the grain is dried by passing air through it by means of a fan heater 10 either at 9‹C above ambient or at ambient temperature when the relative humidity is less than 65%, and finally the grain is cooled with ambient air from fan 8. The control unit 18 de-energises the heater elements of fan heater 10 and operates visual or audible alarms when the desired moisture content has been reached. The control unit 18 also de-energises the heater elements if it senses the relative humidity of the air is less than 65% and de-energises fan 8 when the desired grain temperature is reached. The required drying time can be established by measuring the moisture content of a sample of grain.

Title: Preservation of natural rubber latex
Inventor: COLLIER HUGH MARTIN
IPC: C08C1/06
Filed: 1958-09-13
Abstract: Increased preservation of natural rubber field latex, both at normal concentration and when mechanically concentrated by centrifuging, by electrodecantation, or by heating with agitation, is obtained by maintaining the free ammonia content of the latex at not less than 1,25% of the weight of the serum in the latex and adding thereto a compound which maintains the redox potential of the latex in an oxidative condition but has no appreciable deleterious action. Preferably, the compound is added in a proportion of 0,01%-0,25% by weight of the serum in the latex, to produce redox potentials of the rubber latex immediately after the addition of at least 125 mv. but not greater than 200 mv. Examples of compounds which can be used are the borates, iodates, bromates, dichromates and ferricyanides of the alkali metals and ammonium.  According to an example, the ammonia content of a field latex was adjusted to 0,35% NH3 immediately on receipt and 0,02% of ammonium laurate was added to give increased stability to the latex.  The latex was then divided into two halves, one of which was used as "control" and to the other 0,15% of boric acid was added as a solution in ammonium hydroxide.  The two portions of latex were concentrated by centrifuging to a 60% dry rubber content and the ammonia content was adjusted to 0,55%. After subjecting both portions of latex to the conditions of bulk transport for 6 weeks the redox potential of the latex containing ammonium borate was + 138 mv., whereas that for the control was - 117 mv.  In other examples, potassium dichromate and potassium periodate were employed instead of ammonium borate.
