Title: Improvements in or relating to power operated spraying machines
IPC: A01M7/00
Filed: 1955-09-19
Abstract: 773,126. Crop sprayers. JONES, S. H. Sept. 19, 1955 [Nov. 19, 1954], No. 26716/55. Class 69 (3). Liquid insecticide &c. from a barrel 14, mounted on a framework 15 secured to the rear of a tractor, is fed through a tap 24 on to a rotor 1 mounted on a shaft 2 and driven at high speed from the tractor power take-off 8. The rotor is dish-shaped with concave vanes 9 extending over the edge of the rotor. The centre line of each vane is tangential to a circle 11, Fig. 2, and the concave surface of each vane faces the direction of rotation. An inwardly bent tip 9a at the outer end of each vane assists the dispersion. To prevent forwardly directed spray reaching the tractor, especially when commencing spraying operations, a conical shield 33 is provided which delivers forwardly directed spray to a second vaned rotor 35 mounted on the rotor shaft. A universally mounted spout may be fitted to the tap 24 so that the position of liquid impingement on the rotor may be varied. A lever regulates discharge from the tap and is controlled from the driver's seat by a rod 26. A float valve in the barrel, or in a smaller container adjacent the barrel, may control the tap valve so that discharge is controlled in accordance with the height of liquid in the barrel. The latter may feed two vaned rotors driven in opposite directions.

Abstract: 1,137,839. Rolling. ROTARY PROFILE ANSTALT. 25 March, 1966 [29 March, 1965], No. 26778/68. Divided out of 1,137,838. Heading B3M. An apparatus for profiling solid workpieces 26 by plastic deformation comprises at least three rollers urged towards each other to deform the workpiece floatably held between them and frictionally rotated by them. The apparatus preferably comprises three rollers 10, 12, 14, each having a recess 22 extending around its circumference so that as the rollers move towards each other the workpiece is progressively squeezed. The rollers 12, 14 are preferably movable whereas the roller 10 is mounted on a fixed axle 18 and is driven from any suitable means. The inward movement of the rollers is limited by the shoulders 33. Escape gaps (34), Fig. 4 (not shown), are formed between the three shoulders at each side of the workpiece through which any excess material may flow. The flash is removed in a subsequent operation.

Title: A manner of and apparatus for closing and securing small bags
IPC: B65B7/08
Filed: 1930-09-09
Abstract: 365,137. Closing and sealing paper &c. bags. BROOKE BOND INDIA, Ltd., 2, Metcalfe Street, and WOOD, C., 3, Hide Road, Kidderpore, both in Calcutta, India. Sept. 9, 1930, No. 26891. [Class 94 (i).] Paper &c. containers are closed and sealed by scoring a line along the flap or portion of the bag that is to be turned over to determine the length thereof, folding over the flap &c. along the scored line, gumming the flap &c. along a determined line and crimping the turned over portion to the container along the gummed line. Small paper bags, previously filled with tea &c., are fed by conveyer bands, with their open ends 16, Fig. 2, uppermost between a scoring disc 13 and rotating plate 18 which crease the upper end of the bag and bend it over towards the bevelled surface 9 of a gumming wheel 1. The gumming wheel is mounted on the shaft 8 of the scoring disc and, being slightly larger than the disc, applies a strip of gum with a wiping action across the top of the bag. During the further progress of the bag, a folding plate bends over the top part of the throat, about the crease 35, Fig. 7. As shown, one side of the bag extends above the other forming a flap 31 and the strip of gum 33 is applied with its centre at the base of the flap. The folded ends pass between crimping or knurling rollers 24, 24a, Fig. 5, disposed between plain rollers 25, 26. The crimping rollers indent the sides of the bag with small indentations in staggered relationship and spaced apart by distances rather more than their width. The plain rollers squeeze the gum and force it mostly into the crimped area. Additional crimpings may be effected above or below or above and below the gummed strip. The arrangement separates the gum from the contents of the bag by a line of crimping and a sharp fold, thereby preserving the contents from contamination by the gum.

Title: Improvements in or relating to electrical circuit interrupters
IPC: H01H9/20
Filed: 1925-10-27
Abstract: 263,217. Harlow, P. L., and Metro politan-Vickers Electrical Co., Ltd. Oct. 27, 1925. Latching and unlatching.-An electric circuit interrupter is provided with a stop which, when the interrupter is tilted from its normal position into a position in which it might be closed through the action of gravity alone, is operated or controlled directly or indirectly by gravity so as to take up a position in the path of the movable member of the interrupter and thereby prevent closure thereof. In Fig. 1, the spring- controlled moving contact 17 is pivoted at 19 to an arm 21 on a shaft 23 which is rotated clockwise to close the switch. If the panel 15 is tilted in a clockwise direction, the contact 17 will tend to close the switch and to prevent this a pin 27 on the arm 21 is made to engage a slot 31 in a pendulum 29 which is free on the shaft 23. In the event of the panel being tilted counter-clockwise a fixed stop 32 engages the pendulum and prevents it from moving the pin and closing the switch. Fig. 2 shows another form in which a closing magnet 33 co-operates with an armature on an arm 37 formed with a toe 39. When the panel is tilted clockwise, a ball or roller 43 moves along a slot 41 and, by engaging the toe, prevents closure of the switch. A recess in the slot prevents, the ball or roller from moving until the panel has tilted through a certain angle. In Fig. 4, a latch 47 is held up by an electromagnet 49 in circuit with which is a mercury tilting switch 51 which, when the panel tilts, de-energizes the electromagnet 49 and releases the latch to prevent closure of the switch. In another form, the latch may have a heavy depending part which prevents closure when the panel is tilted.

IPC: C08F6/14
Filed: 1946-09-10
Abstract: Polymers or copolymers of styrene or styrene derivatives prepared in aqueous emulsion in the presence of an anionic emulsifying agent are precipitated therefrom by means of an aqueous alkaline solution. Suitable alkaline substances are sodium and potassium hydroxides, carbonates, bicarbonates and trisodium phosphate.  Most satisfactory precipitates are obtained by adding the polymer emulsion to the alkaline solution which may also contain a small proportion of water-soluble organic compounds such as methanol to increase the extraction of the emulsifying agent.  The precipitated polymer is then preferably washed with the alkaline solution and dried. Specified anionic emulsifying agents are isopropyl naphthalene sodium sulphonate, decyl and dodecyl benzene sodium sulphonates, sulphated lauryl alcohol, sulphonated poly - alkylene ether alcohols and the dioctyl ester of sodium sulphosuccinic acid.  Polymers specified are those of styrene, methyl styrene, a -methyl-para-methyl styrene, nuclear-halogenated styrenes and copolymers of styrene and methyl methacrylate.
