Patent GB-696093-A (GB)
Title: Improvements in attachments for controlling the filling and permitting the emptying and draining of tanks
Inventor: DAVIES ROBERT HENRY
IPC: G05D9/04
Filed: 1951-04-03
Abstract: 696,093. Filling and emptying tanks. PARKER APPLIANCE CO. April 3, 1951, No. 7667/51. Class 21 [Also in Group XXIX] A device for controlling the filling and permitting the emptying of a tank comprises a housing 1, Fig. 2, fixed to the wall of a tank 3 and having an inlet 7 normally closed by a spring-loaded valve member 17 engaging a seat 8, and an opening 10 having a seat 11 and leading via ports 13 to the interior of the tank, the closure member being attached to a diaphragm 15 controlled by a floatoperated valve 33 positioned adjacent the top of the tank. To fill the tank, a nozzle 25 is attached to the housing by a coupling 27 and a closure member 29 is unseated by operation of a rod 30 thereby moving the member 17 to a position intermediate the seats 8, 11 and admitting liquid to the tank. Some of the liquid passes through a line 45 to the valve 33 the piston member 35 of which connects the line 45 to the space above the diaphragm whereby the member 17 is held against the member 29. When the level in the tank raises the float 51, the piston member moves to connect the line 45 to the space beneath the diaphragm, and the space above the diaphragm to exhaust through a port 53. Thus the diaphragm moves the member 17 onto seat 11 to stop flow into the tank. When the supply pressure is removed by seating the member 29, the pressure beneath the diaphragm bleeds off through an orifice 54 permitting the spring 23 to move the member 17 onto the seat 8. The nozzle may then' be removed. To empty the tank, a nozzle containing means for unseating the member 17 is connected to the housing. In another arrangement, the supply pressure acts beneath the diaphragm 68, Fig. 4, and also in a chamber 79 above the diaphragm through a passage 77. An outlet 81 from the chamber 79 is controlled by a float-operated valve member 84, opened when the liquid in the tank raises the float 91, whereby the pressure beneath the diaphragm moves the member 64 onto its upper seat 63. On closure of the nozzle valve, the pressure acting beneath the diaphragm falls to that due to the liquid in the tank and substantially equals that acting above the diaphragm, thus permitting the spring 76 to move the member 64 onto lower seat 59. Specification 663,749 is referred to.

Abstract: 1,166,205. Mixing apparatus. A. J. LUSCOMBE. 21 Feb., 1968, No. 8419/68. Heading B1C. [Also in Division B8] A trailer vehicle for mixing animal feeding- stuffs has a generally rectangular, container with bottom, top and front mixing conveyers BC, TC and UC respectively, the bottom conveyer being driven at a slower rate than the other two. As shown they consist of endless chains as at 25 with widely spaced slots as at 25a. The apparatus is loaded through the runs of the top conveyer and is discharged by pivoting the upper part of the upright front conveyer UC about a shaft 22a into the position shown by broken lines, when it conveys material through a shoot 24 on to a transverse screw conveyer A. The front sprocket shaft 26a of the top conveyer has short screws (28 -Fig. 2, not shown) at each end to clear material from the container walls; the top conveyer may be replaced by three parallel endless chain or screw conveyers (see Figs. 5 and 6, not shown), the middle one being driven at greater speed or having greater pitch than the other two. The apparatus is driven by a power take-off P from the tractor, through chain gearing (see Figs. 1, 2, 4 and 7, not shown). The bottom conveyer may be reversible to load and discharge material to be mixed, or packaged goods for transportation, through the hinged tail-gate 15.

Title: Improvements in centrifuges for separating solid particles from gases
IPC: B01D45/14
Filed: 1942-06-19
Abstract: 560,172. Centrifugal separators. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. June 19, 1942, No. 8425. Convention date, June 21, 1941. [Class 23] A centrifuge for separating solid particles from a gas stream comprises, either, several coaxial cylinders providing annular spaces through which the gas passes in an axial direction, or, a spiral surface of several convolutions between which the gas passes from the centre to the periphery. In the former case, the gas is introduced to the annular spaces through nozzles which give it a tangential velocity conforming to the peripheral velocity of the adjacent cylindrical walls. In the latter, the radial depth of the spiral passage decreases towards the periphery so that the gas is speeded up to correspond with the increase in the peripheral velocity of the spiral walls as the diameter increases. The gas to be cleaned is pumped into a space 34a, Fig. 1, where it is subjected to water sprays from nozzles 36. Thence it passes through nozzles 40 which give it a tangential velocity, to the annular spaces between cylindrical walls 20. Between the inner walls there are entry blades 27 which reduce the ingoing tangential velocity to conform to the velocity of the adjacent walls. The gases emerging at the upper end pass between guide blades 38 which convert the gas velocity into an axial one. Water sprays 52 are' directed against the outgoing gas. To secure a constant velocity with varying flow volumes, the walls 41 of the nozzles 40, Fig. 2, are flexibly mounted and are moved, to vary the nozzle openings, by means of a device 46 responsive to the drop of pressure in the nozzles. The walls 20 may be replaced by a spirally wound sheet. For the removal of solid deposits on the cylindrical walls, in a four-walled construction, the first and third walls are rigid with the shaft. The second and fourth walls are driven from the same shaft but through ratchet pawls which by a secondary movement cause one to rotate a little faster and the other a little slower than the first and third walls. The first, second and third walls carry hinged scrapers which press on the next outer wall under centrifugal force 'and dislodge solid deposits.
Patent GB-1456492-A (GB)
Title: Method of moulding a deformable fabric or thermoformab
IPC: B29C51/00
Filed: 1975-02-28
Abstract: 1456492 Sheet forming J SANSON 28 Feb 1975 [19 March 1974] 8579/75 Heading B5A A sheet of hot- or cold-deformable fabric which has been made airtight by applying an elastic covering to one of its faces, or a sheet of thermoformable plastics material, is moulded in a female mould by sealingly fixing the sheet on the periphery of the mould cavity with a permeable elastic diaphragm interposed between the sheet and the cavity, and establishing a vacuum within the cavity which causes the sheet to adhere to the diaphragm and the sheet and diaphragm to be deformed into conformity with the surface of the mould in such a way that the sheet is caused to undergo uniform stretchthroughout its area. In a first embodiment (Fig. 1), the elastic diaphragm 9 is of varying cross-section, the thinner portions 9a corresponding to the shallower regions 3a of the mould cavity, and the thicker portions 9b corresponding to the deeper regions 9b. A layer 14 of non-slip agent, e.g. polyisobutylene, so that the sheet 8, when adhered to the diaphragm under vacuum, cannot move relative thereto. On the application of vacuum to the mould cavity via connection 6, the thinner portions 9a of the diaphragm deform first, the thicker portions 9b (and therefore the areas of the sheet 8 adherent to the portions 9b) remaining substantially unstretched. When the thinner portions 9a of the diaphragm come into contact with the corresponding regions 3a of the mould surface (Fig. 2, not shown), deformation of these regions ceases, and the thicker regions 9b then deform until the diaphragm is wholly in contact with the mould surface (Fig. 3, not shown). By a suitable choice of profile for the diaphragm 9 it is possible to ensure that the areas of the sheet facing the thinner portions 9a of the diaphragm are stretched as much in the first stage of deformation as are the areas facing the thicker portions 9b in the second stage, so that the sheet is uniformly stretched over its whole area. In an alternative embodiment (Fig. 4) the diaphragm 19 is of uniform thickness and is coated on its face facing the sheet 17 with a coating 20 of a non-slip agent, e.g. polyisobutylene and on the surface facing the mould with a coating 21 of lubricant, e.g. silicone grease, PTFE grease or emulsion, or talc. Such lubrication ensures that during forming of the sheet the diaphragm can slip on the mould surface so that internal stresses can maintain uniform thickness of the diaphragm and so of the sheet adhered thereto. This second embodiment is stated to be applicable to moulds of simpler profile than those to which the first embodiment is applicable. Foam may be cast in the formed sheets to form cushions.
