Filed: 1947-08-11
Abstract: 629,396. Wheels for vehicles. WHITEHEAD, W. R. Aug. 11, 1947, No. 22228. [Class 144 (i)] A detachable wheel is secured on its hub, brake drum or like rotary mounting by a locking means movable solely in one plane (normal to the hub axis) and always remaining on such hub, the locking means in its locking position lying under abutments provided on the hub and pressing body portions of the wheel against the hub, but in its inoperative position allowing free passage of such body portions so that the wheel can be detached ; the hub has a conical portion for centralizing the wheel and the radial faces of the abutments serve to transmit torque to the wheel. A disc wheel 1 has four inwardly-directed segments 3 which seat between four part-circular torquetransmitting projections 6 provided in a ring 7 attached by screws to a groove 8 in, and concentric with, a brake drum 4. The projections 6 have conical wheel-guiding lead surfaces 17 on their radially outer periphery and inwardlydirected lips 11 arranged to retain and overlie the outer portions of radial segments 12 of a locking ring 13 loosely mounted on a flanged bush 14 screwed to the brake drum 4. The width of the segments 12 is such that in the locking position they bridge adjoining pairs of lips 11, and in the release position they are lapped by the lips 11 and allow removal of the wheel. The locking segments 12 have an inclined inner face to wedge against the wheel segments 3 in the locking position and spring- urged pawls 24 fixed to the brake drum 4 engage the trailing edges of the segments 12 to prevent rotation to the release position. Alternatively the pawls 24 may be anchored centrally and engage both the trailing and leading edges of adjacent segments 12 in the locking position or may be in the form of a spring-urged detent extending the width of the gap between the segments 12, to prevent rotation in either direction. In a further arrangement, a stop-pin may be provided near the end of one of the lips 11 to engage arcuate slots in the adjacent radial edges of a pair of locking segments 12. A hub cap 22 snap engages over a bead 20 on the projections 6. A tool to depress the pawls or detents 24 and rotate the locking ring comprises a tubular body 30 with a handle 31 at one end and at the other end, four dogs 32 arranged to fit between the locking segments 12. Alternatively the locking ring 13 may be toothed and rotatable through reduction gearing by a small articulated handle housed behind the hub cap and secured by a clip against inadvertent rotation. In lieu of the retaining lips 11 the locking ring 13 may be retained by a detachable ring or flange on the bush 14 having its inner face stepped or intermittently inclined to wedge the locking segments 12 in the locking position.

Title: Improvements in or relating to gate valves
IPC: F16K31/143
Filed: 1932-08-11
Abstract: 389,724. Fluid-actuated valves. HALL, C., 63, Calle de Amberes, Mexico City. Aug. 11, 1932, No. 22477. Convention date, June 23. [Class 135.] A device for attachment to gate valves of the normally manually operated type whereby the valve may be opened or closed from a distance, comprises double-acting piston means adapted to be mounted on the cover of the valve after the removal of certain of the manual actuating elements. Fig. 5 shows one form of attachment for use with valves of the " non- rising stem " type, and is adapted to be put in place after the removal of the existing handwheel, valve spindle and stuffing box. It comprises a pair of cylinders 26 joined by a bridge 27 and mounted on an adaptor 39 adapted to be secured to the cover of the valve casing. Each cylinder contains a piston 28 provided with leather packing 44 and metallic packing rings 43 and mounted on a rod 29 secured to a yoke 30. The yoke 30 carries a spindle 31 adapted to be passed through a stuffing box 41 in the adaptor and screwed into the valve member. For manual actuation a split nut 35 and bracket 36 is temporarily secured in position with the nut engaging a screw thread 31a on the spindle so that as the nut is rotated the valve spindle and valve are raised or lowered as required. Fig. 8 shows a form for use with the same type of valve having a single actuating cylinder 48. With this form manual actuation is obtained by supplying pressure to the upper side of the piston and manipulating a hand-wheel 55 in the upper end of the spindle whereby the thread 46 is screwed into the valve member to move the latter to its open or closed position. When the form of attachment shown in Fig. 5 is used with a valve of the "rising stem type the spindle 31 is replaced by a short spindle having a socket adapted to screw on to the end of the existing valve spindle. When a single cylinder is used with this type of valve, the cylinder is arranged to one side of the valve spindle and the upper end of the piston-rod has a bracket carrying a rotatably mounted nut engaging the existing spindle. By applying pressure to the upper side of the spindle and rotating this nut the valve may be manually actuated. Pressure may be supplied to the cylinder or cylinders to actuate the valve from a pump or any source of air or other fluid under pressure. When water is used the control pipes are initially filled by opening cocks in the cylinder ends of the control conduits and supplying water until it overflows through these cocks after which they are closed. Fig. 6 shows one arrangement for supplying the controlling pressures. Each control conduit is provided with a safety valve 20, an exhaust cock 18, a supply cock 16 and a pressure gauge 24 and the two conduits are connected to the outlet of a pump 15.

[Class 94 (i).] A device for opening flattened bags and feeding them to a packing machine comprises means for engaging the flat bottom of the lowermost bag of a pile of bags and transporting it into a channel-like guideway in which the individual bags are conveyed to a device for opening the bag into rectangular form and then conveyed to the receiving station of the packing- machine. An oscillating knife 22, Fig. 2, engages the lowermost bag of a pile B resting on an inclined plate 1 having a cut-away part 1a adapted to expose the bag and allow the knife to enter between the folded bottom and the body of the bag and to feed it to feed and guide rollers into a channel 35 having an inclined wedge part 41 and guides 42, 44, the bottom of the bag resting on a rail 38 rigid with the bottom 39 of the channel. The bag is then moved along the channel to the opening means by drivers 46, 47 slidable on a shaft 53 in a direction parallel to the length of the channel 35. The drivers then turn about the shaft to clear the bag and to perform their return movement. The opening device comprises a reciprocating pipe 65, Fig. 4, connected to an air supply and provided with a spring- controlled slide 70 having an inclined lower edge co-operating with an inclined part 74 on the channel 35 to grip the edge of the left side of the folded bag shown in dotted lines. An inclined nozzle plate 78 of the pipe 65 has projections normally supporting a bifurcated hook 90. As the nozzle descends, it enters the bag and allows the hook to move to the right while supported on a roller 87. When the nozzle is in the bag, air is blown through the pipe and a finger 82 passing through an opening 35a in the channel engages the bottom of the bag to facilitate its opening into rectangular form. The hook is then returned to the left and the nozzle in its upward movement engages it and moves it clear of the bag. Drivers similar to the drivers 46, 47 and mounted on the same supports then move the opened bag further along the channel 35 to the receiving station of the packing-machine.

Title: Method of determining the internal resistance of an electrolysis cell and an apparatus for carrying out this method
IPC: G01R27/16
Filed: 1975-05-23
Abstract: 1514182 Measuring resistance ALUMINIUM PECHIN 23 May 1975 [5 June 1974] 22748/75 Heading G1U In determining the internal resistance of an electrolysis cell, a small A.C. signal i c  is superimposed on the normal cell D.C. from the current i c  and the cell terminal voltage the active part r f  of the cell impedance is determined and this value is extrapolated to zero frequency to provide a measure of the resistance. The cell 1 is for extracting aluminium from an electrolyte of alumina dissolved in cryolite, and has current supplied over busbars 3. A current injection circuit 8 superimposes a small A.C. of frequency f on the cell current between the poles 50, 51. An inductive probe 4 Fig.2 (not shown) detects the A.C. signal and produces an output i(f) corresponding thereto which is fed to a synchronous detector 11. The voltage between the cell poles passed via over-voltage protection 6 and A.C. separator 7 to an input of a second synchronous detector 11. The reference inputs to the two detectors 11 is a squarewave derived from the generator 9 supplying the injected A.C. The detector outputs are thus representative of the moduli of the alternating current and voltage components. These are supplied to a divider 12 which provides an output corresponding to the active component of the cell impedance, this being indicated at 14. Determination of this active component at several frequencies, allows an extrapolation back to zero frequency, which provides an indication of the cell resistance R. In a further embodiment Fig.22 (not shown), a current shunt (207) outside the points 50, 51 provides a measure of the cell D.C. and this is multiplied by the resistance R and subtracted from the D.C. component of the terminal voltage, to indicate the cell counterelectromotive force in this embodiment.

Abstract: 1,091,278. Carrier frequency systems. SIEMENS A.G. May 23, 1966 [May 24, 1965], No. 22805/66. Heading H4R. In a carrier frequency communication system in which a basic group of twelve inverted speech bands is produced by a method including the modulation of each speech band to a common frequency band from which individual carrier frequencies modulate the respective speech bands to their final position in the basic group, the common frequency band is lower than, and the individual carrier frequencies are higher than, the frequency range of the basic group, and the common frequency band outputs are selected by mechanical channel filters. Fig. 3 illustrates the formation of a basic group of twelve speech bands in the range 60 to 108 kc/s. by a premodulation of the 4 kc/s, speech band with a 48 kc/s. carrier from which the upper sideband is selected by means of mechanical filters such as those of Specification 1,075,556. The speech signals in the common band of 48 to 52 kc/s. are modulated by respective carriers 112, 116, 120 ... 156 kc/s. to the group frequency range 60 to 108 kc/s. where they are selected by a group filter. Carrier frequencies are generated from a basic 4 kc/s. signal by multiplication in V1, Fig. 5, to form auxiliary frequencies 12 and 20 kc/s. Further multiplication in V2 forms some carrier frequencies direct while others are developed by intermodulation in modulators M1 to M8. Prior art modulation systems are described with respect to Figs. 1 and 2 (not shown).
