IPC: F04C18/16
Filed: 1936-02-03
Abstract: 460,865. Meshing - screw compressors. AKTIEBOLAGET MILO. Feb. 3, 1936, No. 3263. Convention date, Feb. 12, 1935. [Class 110 (ii)] In a meshing-screw type of compressor, a difference in pressure arising in two working spaces such as P, R, which are approaching one another, is prevented by means of communication being provided between the spaces before they merge into one space, so that the same pressure exists in the two spaces. Inlet and outlet ports 62, 64 for the gas being compressed are provided. A passage 80 may be provided in the casing allowing the spaces P and R to be in communication during compression. Fig. 3 shows another method in which a.plate 88 cuts off an area e, f, g, h, k, m. The space P is open to the induction side until the front edge a of the thread T<1> has reached the positon a<1>. At this moment the point G on the thread S moves past the point M, and compression takes place in the spaces P, R, simultaneously. In place of the plate 88, the casing part 30 may be provided with channels which connect the space P with the induction side until the edge a reaches the position a<1>. The rotors 10, 12, are mounted in roller bearings 16, 18, 20, 22, which take up radial pressure, and ball-bearings 24, 26, to take the axial loads. Packings 32, 34, 36, 38, are provided. Gears 42, 44, couple the rotors together so that the rotors do not make contact with each other. Cooling liquid is circulated through the rotors by way of inner tubes 46 and return spaces 46<1> outside the tubes 46. A packing ring 71 may be provided.

Title: Improvements in and relating to the manufacture of titanium dioxide
Inventor: BRISTOW HOWARD ARTHUR STANLEY
IPC: C01G23/07
Filed: 1958-01-31
Abstract: In the manufacture of titanium dioxide by vapour phase oxidation of titanium tetrahalide with an oxygen containing gas, wherein the reaction is effected in a fluidised bed of refractory particles at 750 to 1,500 DEG C., the size distribution of the particles of the bed is controlled by withdrawing, continuously or intermittently, particles from the bed and replacing them by particles from an outside source having a mean particle size smaller than that of the particles withdrawn.  The added particles may be alumina, silica, zirconia, zircon or preferably titanium dioxide.  Such a process produces pigmentary titanium dioxide which is entrained and removed, as well as a hard titanium dioxide which is retained as an accretion on the particles of the bed.  It is preferred that at least 40% of the titanium dioxide produced is so retained.  If a pure titanium dioxide product is required, the titanium dioxide particles added may be in the form of aggregates formed by drying a slurry of finely divided titanium dioxide for example by spray drying; preferably titanium dioxide particles withdrawn from the bed are reduced to the required size and recycled.  Alternatively if composite material for use in vitreous enamels is required, containing for example up to 20% of silica, alumina, zirconia or zircon, the material added to the bed consists of particles of such components.  According to an example, a bed of titanium dioxide particles was heated to 950 DEG C. and then fluidised with a mixture of titanium tetrachloride, oxygen and carbon monoxide, the latter providing additional heat to maintain the reaction temperature.  The particle size distribution and the volume of the bed were kept substantially constant by withdrawing about 10% thereof by weight per hour and replacing it by titanium dioxide particles having a smaller mean particle size.  Approximately 50% of the product was carried overhead as pigmentary titanium dioxide while 50% remained behind as accretions of the initial particles; the latter was employed, after grinding for use in a vitreous enamel.

Title: Improvements in or relating to hermetically sealed tins, canisters, jars and like containers
IPC: B65D43/02
Filed: 1937-02-04
Abstract: 489,859. Closures for cans and other containers. BENNETT, G. H. Feb. 4, 1937, No. 3339. [Class 125 (iii)] A container 1 is adapted to be hermetically sealed by a jointing ring 4 which fits between the lower part of a groove 3 in the container wall and the beaded edge of the peripheral flange of the sheet metal cover 2. This flange has internal projections 5 which engage the upper edge of the groove 3, being snapped into position when the cover is forced on to the closing position in which the edge of the flange engages the ring 4 prior to the vacuumization of the container. The locking projections 5 are far enough apart to enable any excess of gas within the container to escape by springing the cover between the projections. The container may be of circular or rectangular cross - section and the cover may be of dished form as shown in Fig. 1. There is sufficient clearance between the flange and the container to permit a lateral compression of the cover, after the ring 4 has been moved from its normal position, to disengage the projections 5 from the groove so that the cover can be removed. Specification 474,226 is referred to.

Abstract: 798,937. Battery charging systems. STONE & CO. (DEPTFORD), Ltd., J. Feb. 1, 1957 [Feb. 3, 1956], No. 3456/56. Class 38 (4). In a battery charging system for, say, a vehicle, having a voltage and current operated cut-out, the voltage winding 20 is arranged to be responsive to the difference between the generator voltage, and only part of the battery voltage. A battery 1 is connected to a potential divider 13 and also to a variable speed generator 2 through normally open contacts 5 and a current coil 22. A potential coil 20, together with a rectifier 14 and normally closed contacts 21 are connected across contacts 5 and part of divider 13. When the generator voltage exceeds the fraction of the battery voltage determined by tap 12, coil 20 will be energized closing contacts 5. When the generator voltage falls below that of the battery, the reverse current flowing through coil 22 opens contacts 21, deenergizing coil 20 and opening contacts 5, breaking the current through coil 22 and reclosing contacts 21. The potential divider 13 may be omitted and tap 12 taken to a tap on the battery. In another arrangement a contact on an auxiliary voltage-operated relay is connected in series with divider 12 to disconnect it from the battery, and a separate voltage coil employed in conjunction with coil 22 to operate contacts 5.

Reeling - machines; swifts.-The swift 8 in a reeling-machine is supported on an arm 2<1> oscillatably mounted on a stud 2, and it comprises a hub 10 fixed on a sleeve 9 and provided with arms 11 which carry hank-supporting frames 14, the frames 14 being also jointed by links 15 to arms 16 on a collar 17 slidable on the sleeve 9. The swift is driven by means of a wheel 13 on the hub 10 from a wheel 12. A spring tends to force the collar 17 away from the hub 10 and thereby to maintain the hank supports 14 in their operative positions. The sleeve 9 is fixed in position between the arm 2<1> and a set-ring 21 on an internal sleeve 20, which is clamped to the arm 2<1> and is provided at its outer end with a sliding member 22. The movements of the member 22 are limited by a screw 23 engaging a slit 24 in the sleeve 20. The member 22 carries an axial rod 25 to which is attached one end of a tension member 26 that passes through the arm 2<1> over pulleys 27 - - 29 through a hole 30 in the frame 1 and carries an adjustable stop 31 and a weight 32. During winding the swift is held in the position shown in full lines by the engagement of a spring-pressed lever 6 with a nose 7 on the frame 1. When the hank is wound the drive is stopped, the lever 6 is disengaged from the nose 7, and the arm 2<1> is turned down into the position shown in broken lines in Fig. 2. During this movement, the weight 32 is raised until the ring 31 is arrested against the frame 1, and, on further downward movement of the arm 2<1>, the sleeve 22 and collar 17 are displaced towards the hub 10 and the diameter of the swift thereby reduced. The hank is then removed and the arm 2<1> swung upwards, the members forming the swift resuming their original positions under the action of the spring 18.
