Title: Improvements in expanding wheel gearing
IPC: F16H15/42
Filed: 1945-09-18
Abstract: 599,566. Expanding wheel gearing. RONAI, E. Sept. 18, 1945, No. 24125. Convention date, Aug. 30, 1944. [Class 80(ii)] In an expanding wheel gear, the transmission means consists of an inner ring, contacting the bevel members, and an outer ring rotatably mounted on the inner ring and arranged to be driven by the inner ring when the latter is deformed by taking the load. Parallel input and output shafts 22, 33 carry on their splined portions 23, 34, the cones 18, 19, 20, 21 of two expanding wheels. Drive between the wheels is transmitted by a rigid ring 5 having bevelled edges 6 and an annular flange on its periphery. A second ring 11 is mounted on the ring 5, and secured thereon by a grub-screw secured collar in such a manner that deformation of the ring 5 in transmitting the drive causes the ring 11 to rotate rigidly with the ring 5. On cessation of the drive, the ring 5 is no longer deformed and the ring 11 is free to revolve on the ring 5 to dissipate its kinetic energy. Lateral adjustment of the cone members 19, 21 is effected by a rack and pinion mechanism 27, 28 on the housing 25 of the bearing 24 for the cone member 19, and by torsion spring adjusted spindle 45 and the slide blocks 42 to a housing 36 for a thrust bearing 35 of the cone member 21.

Title: Self-locking structure
IPC: F16J15/52
Filed: 1962-06-22
Abstract: 945,287. Fluid-pressure brakes; diaphragmpistons. BENDIX CORPORATION. June 22, 1962 [June 30, 1961], No. 24149/62. Headings F2F and F2T. In a fluid-pressure servomotor actuating an automotive hydraulic braking system and having a housing formed by two generally tubular stampings A, B, a piston diaphragm C is sealingly clamped at its outer periphery between an annular shoulder 12, formed internally of a cylindrical end portion 10 on the stamping A, and a peripheral flange 20 on the stamping B which slidingly fits within the portion 10 and is locked therein by a number of resiliently yieldable tabs 26 sheared at angularly spaced intervals in the portion 10 outwardly of, and inclined radially inwardly to, the shoulder 12. The tabs 26 are formed by slotting the cylindrical portion 10 at 22 and bending the parts between the slots and the outer edge 24 of the portion so as to provide a generally conical shape to the tabs 26. During assembly, telescoping movement of the stampings A, B will cause the outer edge of the flange 20 to ride down the inclined surface 30 of the tabs 26 until it slides past and outwardly behind the inner edge 28 of the tabs to lock the stampings together. The diaphragm is formed with an outer peripheral bead 14 to provide the necessary sealing pressure between the shoulder 12 and the flange 20. For disassembly, the tip of a screwdriver is placed over the outer surface of the section 16 of the stamping B to successively pry the inner edge 28 of the tabs 26 outwardly of the flanges 20 whereupon the gasketing pressure of the bead 14 forces the flange 20 outwardly beneath the inclined surface 30.

Abstract: 909,686. Packaging and stacking devices. UNILEVER Ltd. July 22, 1959 [July 28, 1958], No. 24177/58. Class 94(1). Apparatus for stacking articles either on a support or in a container comprises a tilting platform 14 on which a layer of articles is positioned from a supply platform 1 and which platform 14 is tilted through 90 degrees to deposit the layer of articles on to a stacking platform 48 and then returns to its original position. In one embodiment, Figs. 1 and 2, articles are supplied by a conveyer moving in the direction of the arrow A on to the supply platform 1, the foremost article contacting a micro-switch at 2 so that a pusher 4 pushes the row of articles on to fingers 5 forming a slotted zone of the platform 1. A second row of articles forms on the platform 1 and the pusher 4 pushes it on to the fingers 5 and the previous row is pushed on to the tilting platform 14. When the platform 14 is full the front row 44 contacts a lever 40 and this causes the platform 14 to be tilted and its fingers 49 pass upwardly between the fingers 5. The platform 14 is moved forwardly and downwardly so that fingers 46 on its foot part pass through slots 47 on the stacking platform 48 to deposit the vertical layer of articles on this platform. The platform 14 returns to its starting position without its fingers 49 passing downwardly between the fingers 5 on which a row of articles has been deposited. The means for moving the platform 14 comprises a member 17 pivoted to the platform 14 and the frame at 16 and 20 respectively, a member 18 pivoted to the platform 14 at 19 and a member 22 pivoted at 23 and 20 to the member 18 and the frame respectively, the four points 16, 19, 23, 20 forming the four vertices of a parallelogram. The articles may be stacked in a box 51 which is intermittently pushed backwards by the oncoming articles and when full descends on to a roller conveyer 64 and a new box is placed on the platform 48. In a modification, Fig. 4 (not shown), the articles are supplied by a conveyer moving parallel to the direction of movement of the rows across the platform 14. Specification 882,092 is referred to.

Title: An improved centrifugal metal-casting machine
IPC: B22D13/10
Filed: 1945-09-19
Abstract: 598,828. Centrifugal casting-machines. SOC. ANON. DES HAUTS-FOURNEAUX & FONDERIES DE PONT-A-MOUSSON. Sept. 19, 1945, No. 24272. Convention date, Dec. 23, 1943. [Class 83 (i)] Metal - pouring.-A centrifugal casting- machine having at least two troughs 3, 4 of which one is in use while another is being cleaned, is provided with trough-supporting means between the mould and the carriage 5 on which the troughs are mounted. The trough 4 in use is supported by a roller 15 on arms 16 of a shaft 17 mounted on a carriage 2 which supports the rotating mould 1 shown in broken lines in an intermediate position.' As the mould moves towards the carriage 5 to enclose the trough 4, a notched guide-bar 27 carried by a spring-raised lever 28 is moved out of the way by a rod 34 of the carriage 2 engaging a roller 36. When the mould reaches the end of its stroke the ladle 12 is tilted to discharge metal and the rotating mould 1 is moved slowly in the reverse direction so that the metal is deposited therein in the form of a spiral. As the mould reaches the position shown the bar 27 rises to engage both troughs 3, 4 and towards the end of its movement an arm 19 of the shaft 17 engages a fixed ramp 23 and thus moves the roller 15 in the direction of the arrow and away from the trough 4 which is thus lowered on to a rail 39 mounted on the carriage 2. A fluid pressure device 7 then moves the carriage 5, the troughs 3, 4 and lever 28 laterally of the mould, to bring the clean trough 3 into line therewith, moving it from a fixed rail 40 on to the rail 39 and, at the same time, moving the trough 4 from the rail 39 on to a fixed rail 41. The mould is again moved towards the carriage, a ramp 25 causing the roller 15 to return to the position shown and the cycle of operations to be repeated with the trough 3, the rod 35 taking the place of the rod 34. In a modification the bar 27 is replaced by guides movable in other directions, e.g. upwards. The roller 15 may be in two parts adapted to be retracted axially each to its own side.

Title: Method and apparatus for manufacturing synthetic mica
IPC: C01B33/42
Filed: 1957-07-31
Abstract: <PICT:0868826/III/1> <PICT:0868826/III/2> <PICT:0868826/III/3> In a furnace for melting powdered or granulated material, especially for making synthetic mica, by passage of current therethrough between a pair of primary electrodes 16, 18, Fig. 1, extending up into the material in the furnace, two secondary electrodes 20, 22 are connected to the primary electrodes so that they extend up at an angle of 20-50 degrees from the horizontal with their free ends close together.  A layer 78 of lamp black is placed between these free ends for starting the furnace, and a downwardly and outwardly extending pool of molten material is formed.  When this pool has reached the primary electrodes, the thinner secondary electrodes, if not consumed, are removed as in Fig. 2.  The electrodes may be of platinum, molybdenum, silicon carbide or graphite and extend up through apertures in a ferrous base 32 of the furnace.  A suitable batch for making fluor-phlogopite mica consists of K2SiF6 19.4%, orthoclase feldspar 19.0%, SiO2 23.9%, Al2O3 8.8% and MgO 28.9%.  An excess of fluorine and potassium is required.  The heating is continued until a pool 76 of molten material is formed.  The pool is surrounded by a sintered layer 74 of the granular material 68, and in order to allow escape of gas, e.g. fluorine, the top of the layer 74 is broken at 80.  The top of the furnace may be covered by a wooden board 56 with a hood 60 having an aperture 62 for viewing, an aperture 64 for removal of fumes and an aperture 66 for adding raw material through the hole 80 to the melt, in order to keep its surface level with the top of the electrode.  The furnace then cools slowly to allow crystal growth, and its contents are broken up to obtain the product.  The furnace shown in Fig. 5 is rectangular in cross section and contains at least three primary electrodes, two of which (1081) carry secondary electrodes 112 for starting the melting. The primary electrodes extend up through the furnace base preferably in pairs across the furnace, only the pair 1081 at one end being energised at first.  When the pool of molten mica has reached the next pair of electrodes 10811, they are also energised, and as the pool spreads towards the wall 102, each further pair of electrodes is energised in turn.  The electrodes are also de-energised in succession in the same order in which they were energised, preferably so that not more than two pairs of electrodes are energised at the same time.  Hence the molten material cools first at one end of the furnace adjacent electrodes 1081 and then cools progressively towards the opposite wall 102 of the furnace, whereby impurities tend to move towards the wall 102 as in purification by zone heating and on solidification the crystals are oriented to form "books" of mica.

Abstract: 1,009,737. Ramps; platform elevators. J. G. BROWN. Sept. 17, 1964, [June 19, 1963] No. 24361/63. Headings B8E and B8H. Vertical movement of a platform 11 on a ship is controlled by a hinged ramp 12 or sensing arm resting on the quay 14, the arrangement being such that pivoting of the ramp or arm due to rising or falling of the ship main - tains the platform substantially level with the quay. As shown in Fig. 2, the ramp is hinged to the platform by means of an hydraulic rotary actuator 13, and an actuating lever 16 is secured to the ramp or hinge and is arranged to operate the spindles of two opposed valves 17, 18 mounted on the platform and controlling hydraulic apparatus for raising and lowering the platform. The ramp is thereby automatically retained within the limits 12a, 12b defined by the positions of the two valves. In a modification, Fig. 4 (not shown), the lever 16 is mounted on the platform 11 and is rotated by a sensing arm connected at one end to the lever 16 and having its other end resting on the quay. A time delay may be incorporated in the control circuit to prevent movement of the platform in response to movements of the ramp or arm caused by surging of the ship due to sea conditions.
