Title: A process for preparing an iron compound from solutions of iron and its conversion to iron oxide
IPC: C01G49/06
Filed: 1927-08-09
Abstract: 300,233. Neill, O. S. Aug. 9, 1927. Insecticides; weed-destroying compositions.- In a further development of the process described in Specifications 230,774 and 251,310, [both in Class 1 (iii), Oxides &c., Metallic], an ironcompound containing liquor such as waste pickle liquor or ferrous sulphate is treated by causing the liquor to break up into particles or globules which, by contact with a rapidly rotating element, are given a rapid rotary, gyratory or whirling motion and subjected while in such motion to the influence of a drying medium, such as hot air, or waste gases. The product is obtained in the form of individual hollow bodies or shells, which are particularly useful as an insecticide, or a weed-killer. Two methods of carrying out the invention are described. In the first method, the solution is broken up by causing it to spread by the action of centrifugal force in a thin film on the surface of a rapidly rotating disc, preferably dished, in such a manner that the globules are formed before they are thrown outwards from the disc into the drying medium. For example, the device according to Specification 264,049, [Class 69 (iii), Spray-producers &c.], may be adapted for this purpose. The solution may also be broken up by means of a spray or atomizer, and the globules directed upon the surface of a rapidly rotating element for the purpose specified.

Title: Improvements in and relating to high vacuum distillation
IPC: H04B14/02
Filed: 1937-07-29
Abstract: 500,195. High - vacuum distillation. KODAK, Ltd. (Eastman Kodak Co.) July 29, 1937, No. 21065. Addition to 482,883. [Class 32] The process described in Specification 482,883, in which liquids are subjected to high-vacuum short-path distillation while spread out in films thinner than are obtainable by gravity alone, is improved by collecting the distilland and/or distillate from distilling and/or condensing surfaces by means of a collecting member in motion relative thereto. The distillation may be carried out on a rotating disc 18, Figs. 1 and 2, fed with the distilland by a pipe 22 and provided at its edge with an integral turned-over gutter 20, in which dips a stationary collecting tube 26 facing the direction of motion, to remove residual distilland. Alternative forms of collecting tube are shown at 30, 38, in Figs. 4 and 5. In another form the rotary disc is plane, the collector is a flat scoop, 50, Figs. 6 and 7, and the edge of the disc is enclosed in a guard gutter 48. Another form of collector consists of the enlarged end 60 of a tube 24, Fig. 9, out away so as to embrace the edge of the disc 46. Alternatively' a plane disc 88, Figs. 12, and 13, may be supplied with a V-gutter 26 of adjustable clearance and a scraper 94 which fits resiliently into the gutter and forces the liquid collecting therein' out through a connected conduit. In a complete distilling unit, distilland is fed by a pipe 22, Fig. 14, to the dished centre of a rotating distilling surface 100 heated by a unit 110 ; residual distilland is collected by a scoop 114. The vaporized material condenses on the disc 102 and is collected by scoops 122, 124; the back of the condensing disc is cooled by a liquid of low vapour pressure circulating from feed pipe 116 outwards over the disc to a scoop 118 in the rim 120 and thence back by gravity through a cooling coil 117.' A plurality of these units may be used in one still. An alternative form of integral gutter 134, Fig. 15, may be used to enable distilling and condensing surfaces to be brought closer together.

Title: Improvements relating to dough dividing machines
IPC: A21C5/04
Filed: 1951-09-10
Abstract: 705,315. Dough-dividing machines. MASON, J. V. Sept. 5, 1952 [Sept. 10, 1951], No. 21271/51. Class 87 (2) As the moulding drum 1 rotates, cams 16, 17 engage rollers 14, 15 on a two-armed lever 13 to oscillate a shaft 8 and thus cause a part 9 of the dough hopper to move towards and away from the drum and force dough into the pocket in the drum. As the drum rotates from the filling position, a curved part 11 on the part 9 and a fixed member 12 prevent dough from escaping from the pocket, and a roller 19 moves the piston 2 inwardly to compress the dough in the pocket. After the dough has cleared the member 12, it is ejected by the piston which moves inwardly as the next charge of dough is fed into the pocket. The empty pocket then passes a scraper 18. Blades 24 in the hopper are driven synchronously with the part 9 to separate the dough from the sides of the hopper and feed it towards the drum. A screw 20 is provided for the member 12 for taking up wear. To vary the capacity of the pocket, the piston may be varied in length by forming it in two parts.

Title: Improvements relating to dashpot damping devices
Inventor: WYATT DENNIS
IPC: F16F9/19
Filed: 1960-06-17
Abstract: 994,570. Dashpots. ENGLISH ELECTRIC CO. Ltd. June 9, 1961 [June 17, 1960], No. 21346/60. Heading F2S. A dashpot, e.g. for damping the rapid movements of electric circuit-breakers, comprises a plunger 23 which has a hollow cylindrical portion 16 in which is received, with the interposition of a spring 21, a plunger 13 and which co-operates with a dashpot 22, the plunger 13 being slidably mounted on a reduced diameter portion 15 of a rod 10 which is secured, at its lower end, to the plunger 23 and, at its upper end, to a bushing 11 in a top plate 12. The rod 10 slidably engages within a guide tube 25 which is connected at its lower end, by means of a collar 24, to the dashpot 22 and has a collar 28 attached to its upper end for cooperation with a lift-bridge 29 which is connected to the circuit-breaker operating mechanism, not shown, and is slidably arranged on the tube 25. Compression springs 30, 31 are constrained between the bushing 11 and the tube 25 and the lift-bridge 29 respectively, the spring 30 tending to urge the plunger 23 and the dashpot 22 apart and the spring 31 being compressed when the lift bridge 29 is in its raised position. The cylindrical portion 16 of the plunger 23 has three damping orifices 20a, 20b and 20c and the plunger 13 has three radially-spaced arms 14 whose movement is accommodated in cut-away portions 26, 27 respectively in the collar 24 and the lower end of the guide tube 25. When the circuitbreaker is tripped the lift-bridge 29 moves rapidly downwards and the piston 16 and the dashpot are moved apart due to the action of the spring 30. Towards the end of its travel the lift-bridge 29 strikes the arms 14 of the plunger 13 which is forced downwardly within the cylindrical portion 16 against the action of the spring 21, oil being forced through the orifices 20a, 20b and 20c until the lift-bridge 29 strikes the collar 24. During the contact-closing action the lift bridge 29 picks up the collar 28 so that the plunger 23 co-operates with the dashpot 22 during the final stages of the closing stroke.

Title: Improvements in hand iron pressing machines
IPC: D06F71/32
Filed: 1952-08-26
Abstract: 732,242. Ironing presses. BOOTH, S. July 30, 1953 [Aug. 26, 1952], No. 21403/52. Class 138 (2). A pressing machine including a vertically movable pressing iron 4 adapted to be depressed by fluid pressure means and to be displaced horizontally by hand, has a main fluid control valve 19 adapted to be operated by foot pressure, and a safety device for controlling the operation of the valve 19 provided with operating means requiring a separate operation independent of the foot pressure before fluid pressure can be supplied to depress the iron, whereby inadvertent depression of the iron is prevented. The valve 19 has a plunger 24 which is operated by a foot pedal 20 through a rod 21 and rocking lever 23, but before the pedal 20 can be depressed against the action of a spring 22 to open the valve, a stop element 25 must be moved out of the way of a collar 26 on the rod 21. The element 25 is carried by a pivoted lever 27 operated by means of a Bowden cable 30 and a pivoted lever 31 on the iron 4. The lever 31 also operates a steam valve 32 on the iron. When the valve 19 is open fluid under pressure passes through a line 35 to a cylinder (not shown) whose piston is connected by levers to an arm 5 on which the iron 4 is pivotally mounted. Fluid is also supplied through a pipe 36 and a non-return valve 38 to a cylinder 37 which controls a valve allowing vacuum to be applied to the buck 2 for drawing steam therethrough. When the valve 19 is closed the fluid in cylinder 37 exhausts through an adjustable by-pass bleeder valve 40, thereby delaying the closing of the vacuum valve. The vacuum valve can be operated independently of the valve 19 by means of a pedal 45 which operates a valve 43 in an alternative feed line 42, 44, to the cylinder 37. A hinged or removable pedal (not shown) enables the press to be operated by foot. Modifications.-The stop element, instead of interfering with the operation of the rod 21, may act directly on the plunger 24. The cable 30 may control a master supply valve in the line 35. A solenoid may be used instead of a Bowden cable. The safety device may be operated by foot pressure in place of the hand control 31. Specification 663,131 is referred to.
