Filed: 1917-07-21
Abstract: 116,397. Taylor, W. July 21, 1917. Lenses &c., grind. ing and polishing. -Lenses that have been rough-ground are smoothed by a lap shaped to fit the curve of the lenses, the lap and the lens-holder being mounted upon spindles arranged at an angle to one another. The lap is adapted to seat itsel f upon the lenses without constraint except that due to the feeding-force, which is in the direction of the axis of the lap. The detritus is washed away continuously by a supply of water, and the smoothing abrasive may be supplied in suspension in the water or may be fixed in the lap. The lap D is mounted upon a hollow spindle C mounted in fixed bearings C1, C2 and rotated by a pulley C<4>. The liquid or liquid and abrasive are supplied through the hollow spindle, and are led through grooves I in the lap surfaces, or through the spaces between a number of lenses, to all parts of the surface to wash away the detritus. The grooves in the face of the lap aro arranged in such a manner that the liquid has to traverse substantially the whole of them before it escapes. The lens or lenses F4, F5 are mounted on a holder F2 secured by a chuck F3 to a spindle F carried in a frame F. The frame is secured to a bar F6 mounted to slide in the direction of the axis of the lap spindle C in bearings F7, F8, and is counterweighted. The spindle F is driven by a belt G passing round guide-pulleys G1, G2 on a fixed bracket and a pulley F11 on the spindle. A strut is interposed between the frame F and the axle carrying the pulleys G1, G2 to take any strain due to the tension in the driving-belt and to prevent any constraint being put upon the frame. The spindles are set at an angle to one another,- about 20 degrees if the surface to be smoothed is approximately hemispherical,-and the feed is obtained by pushing the bar F6 through its bearings. The angle between the spindles may be adjusted by mounting the spindle F in a frame carried in circular slides on a part secured to the bar F6. The bearings F7, F8 are open at the top and bottom respectively to allow the bar F6 to be tilted to facilitate attachment or removal of the work.

Abstract: 1319712 Rope railway BALZER & DROLL KG 21 April 1971 [24 April 1970] 10516/71 Heading B7L [Also in Division B3] Apparatus for winding and placing coils in stators of electric machines includes a plurality of transfer tools mounted on carriages 2 which are movable along a track or rail 1, each tool comprising means for holding wound coils and a stator core 6, at least one winding station B, at least one transfer station D where wound coils are transferred to the stator, and drive means for moving the carriages along the track independently of each other. Coils of different configurations are wound at some or all of stations B, E, F1, F2, H1, H2 and the coils are placed on the tools. When the coils are in position, the stator cores are placed on the tools which are then transferred to stations D, G or K where the coils are placed in the stator core slots. Since the coils differ at each winding station, their winding times are different and provision is made for the carriages to by-pass winding stations at which winding is taking place, so that there is no delay in getting the wound coils and stator cores to the placing stations. The length of the guide rail 1 can be varied to suit the number of work stations to be used, e.g. in its simplest form the apparatus comprises the stations A-D. The drive means comprises a chain moving along the rail 1 and a sprocket (17) on each carriage 2, Fig. 3 (not shown). The sprocket is locked by a clutch in response to a control impulse thereby allowing the carriage to move with the chain.

IPC: F16D41/22
Filed: 1929-04-08
Abstract: 331,905. Bolton, A., and English, J. April 8, 1929. Clutches, free-wheel ; differential gearing. - A free-whel clutch, wherein a friction member constituted by a floating nut engages automatically under the torque of the drive, is provided with manual locking means operable independently of which is the driving or driven shaft. In the form shown in Fig. 1, providing forward and reverse drives with overrunning in both directions, a conical shell b forming the driven member is engaged, according to the direction of rotation of a driving-shaft d, by one or other of two cones a', a<2> mounted on opposite threads e<1>, e<2> on shaft d. Light springs (not shown) tend to keep the cones in engagement with the shell so that the drive is automatically taken up when the driving shaft commences to overrun. Locking-means comprise a washer m, rotatable with the shell, and movable axially into frictional engagement with the cone a<2> so that, if the driven shaft is overrunning, the cone will be caused to overrun its thread and lock the parts. The washer, which may be used to brake the shell b, is moved by an operating- fork situated in a collar formed by the shell and a flange a<4>carried by a cylindrical extension of the cone. In a modification using a single cone, the shell is locked to the driving shaft by a dog-clutch member slidable thereon and a radial stop is provided in the thread to limit outward movement of the cone. In this form the shell is enclosed and mav contain lubricant. In a further modification, Fig. 4, the thread is carried by a sleeve v feathered to the shaft. The thread has a radial stop p and locking is effected by moving the sleeve in the direction of the cone, whereby disengagement thereof is prevented by the stop p. The clutch is shown applied to a differential gear for motor vehicles. Two clutches are provided, one at each side of the driving bevel wheel, each conical shell being connected to a road-wheel. Sliding-dog locking-means are provided for one of the clutches. The solid cones shown mav be replaced by hollow cones having external shells.

Patent GB-428413-A (GB)
Title: Improvements in the reactivation of adsorbents
IPC: C01B31/08
Filed: 1934-04-11
Abstract: The reactivation of adsorbents, such as active carbon or silica gel, which have been used for removing hydrocarbons, e.g. benzol, from gases is modified by using coal gas, town's gas or similar industrial gas instead of pure hydrogen in the destructive hydrogenation of the fouled adsorbent.  Preferably, the gas used for the destructive hydrogenation has been purified from sulphur and freed from benzol. As catalysts, any of those described in the parent Specification may be employed, e.g. active carbon is treated with an aqueous solution of ammonium vanadate and used for the removal of benzol until exhausted, after which the fouled carbon is subjected to the action of a stream of town's gas at 200 atmospheres and 440 to 450 DEG  C. The products of destructive hydrogenation are removed by condensation after the release of pressure from the gas.

Title: Apparatus for the digital measurement of an electrical charge fed to a load
IPC: H02H3/20
Filed: 1966-03-11
Abstract: 1,109,953. Measuring electric charge. CIBA Ltd. 11 March, 1966 [24 March, 1965; 3 Sept., 1965], No. 10914/66. Heading G4H. Apparatus for measuring the electric charge fed to a load includes an oscillator the frequency of the pulses from which is controlled according to the current applied to the load, the pulses being fed to a counter for the time period during which the current is applied to the load so that the count in the counter represents the charge on the load. In the embodiment described a constant frequency # 0  is applied to a voltage divider 7 (Fig. 2) contacts (3c, 3d, Fig. 3a, not shown) then positioned to selectively connect into the circuitry resistors (10b, 24a, 24b, 24c) to control the rate of charge of two capacitors (14, 25) and so determine the frequency of the output pulses to the counter. The value of the current applied to the load charge 5 is varied by contacts 3a connecting resistances (63, 64, 65) selectively into the circuitry of a constant current supply (Fig. 4, not shown). A switch (67) may be used to alter the load current by a factor of 0À96487 so that apart from a decimal point, the count in the counter is in Á Val instead of Coulombs. When a fault develops in the apparatus resulting in too high a current being applied to the contact 4a (Fig. 2), (70, Fig. 6, not shown), and consequently a high voltage drop across a load resistor (R 1 ), a relay (105) is energized so that the current supply to a relay controlling the switch contact is de-energized and the switch opened. A lamp (107) is lit to indicate the fault.

Abstract: 459,600. Delivering measured quantities of granular &c. materials. PAGE, E., 267, Falloden Way, Golder's Green, London. April 10, 1935, No. 11036. [Class 106 (v)] In apparatus for delivering measured quantities of granular and like materials a pocketed measuring rotor 13, Fig. 6, mounted between a supply hopper 10 and an outlet 12 is adapted to be rotated by an operating member 27 acting in conjunction with a scale or its equivalent 30, Fig. 3, and capable of being moved from a position of rest into a position determined by a stop, the extent of the movement being selected in accordance with the scale so that the contents of one or a number of measuring pockets may be discharged by a single movement of the operating member. The capacity of the measuring pockets may be varied by means of projections 21 carried by a plate 19 and adjustable axially within the pockets by means of a screwed spindle 22 which is held in adjusted position by the engagement of a spring 25 in depressions 20 on the plate. The operating drum 27 drives the rotor through gearing and is formed with slots 29 for engagement by the finger of the operator who rotates the drum until the finger presses down a lever 31 against the action of a spring until it engages a stop pin 41 (not shown). As the rotor turns, its pockets discharge into a tray 34 which is tipped by the downward movement of the lever 31 to discharge its contents. A scale 30 indicates in what position on the drum the finger should be placed for the delivery of a given quantity of material. In a modified form the rotor is operated through ratchet mechanism by a number of keys or levers. In a further form, Fig. 1, the rotor e moves about a vertical axis over the bottom of a container a and is actuated from a rotatable lid h having a number of depressions p, one of which is selected to be engaged by the finger of the operator, and the lid rotated until the finger contacts with a stop formed by an arm j which carries a circular scale plate q.
