The loader is mounted on a frame 42 pivotally mounted about a horizontal axis 46 at one end and resting on fixed parts 56 at the other end. The shoot which is fed from a hopper and is shaped to orientate the workparts, includes a limit switch which in the event of a shortage of workparts in the shoot de-energizes the loader. Workparts on the support 58 are fed into position beneath the picker 62 by a feeder piston and cylinder 80, 82 and in the absence of a workpart under the picker, the loader is de-energized by a limit switch. The picker 62 is mounted on a carriage 64 reciprocable along a pair of parallel shafts 44 of the frame 42, and is vertically movable by a ram along a plate depending from the carriage and pivoted thereto to permit swinging of the picker if the carriage is jammed and the conveyer 12 still moves, the workpieces being clamped by a pair of picker jaws 128, pivoted to a linkage system 150, 152 and controlled in clamping by a ram 132. As the jaws 128 are lowered links 152 which are geared together for symmetrical movement, engage a stop plate 158 whereafter the jaws 128 pivot about their connections with the links 152 causing the jaw ends 154 to grip the workpart. As a workholder 14 passes the carriage 64, a plunger and block interengagement occurs and the carriage is moved along with the holder, during which time the picker moves down to force the workpart into jaws 32, 34 on the holder 14, these jaws being locked by a cam bar 40 on the holder engaging a stationary track, once the holder 14 has passed under a presser foot 290 for seating the workpart in the holder, and a gauge 298. If the latter is pivoted by a badly aligned workpart, a limit switch L7 is operated and the loader de-energized. The carriage 64 is returned to its starting position by a ram 268 and the picker jaws have released the workpart and have been raised. The whole loading system operates cyclically under the control of limit switches.

Filed: 1935-06-17
Abstract: Copper oxychloride of the general formula nCu(OH)2 CuCl2.mH2O are prepared by reacting compounds of the formula 4Cu(OH)2. RCl (R being calcium or barium), which are described in Specification 425,395, with a suitable salt or acid; or by making a mixture of finely divided metallic copper with copper sulphate or chloride and barium chloride and allowing it to stand in air for several days.  Suitable salts and acids for conducting the first mentioned reaction include cupric sulphate or chloride, the sulphates of aluminium, zinc and nickel, and hydrochloric, nitric, sulphuric and acetic acids.  The presence of a small amount of an ammoniacal salt accelerates the second-mentioned reaction.ALSO:A cupric mixture for agricultural purposes comprises a cupric oxychloride of the formula nCu(OH)2.CuCl2.mH2O and a soluble salt of barium and is neutral or slightly acid in reaction.  Sulphur and soluble or insoluble filling materials, e.g. talc or alkali or alkaline earth metal nitrates and chlorides, may also be present in the mixture.  The mixture may be prepared by reacting compounds of the formula 4Cu(OH)2.RCl (R being calcium or barium), which are described in Specification 425,395, with a suitable salt or acid, a certain amount of a soluble salt of barium being added if such salt is not formed during the reaction. Suitable salts include cupric sulphate or chloride, or the sulphates of aluminium, zinc, and nickel. Suitable acids include hydrochloric sulphuric, nitric or acetic acids.  The soluble barium salts which may be added include the chloride, nitrate and acetate.  The necessary acidity may be provided by the presence of a small amount of a free cupric salt such as the chloride; or alkali or alkaline earth metal acetate may be added which through double decomposition produces cupric acetate and hydrochloric acid.  Alternatively, the cupric mixture may be prepared by making a dry mixture of finely divided metallic copper with copper sulphate or chloride and barium chloride and subjecting this mixture to oxidation, say by allowing it to stand in air for several days.  The presence of a small amount of an ammoniacal salt accelerates the reaction.  According to one example, a cupric hydratecalcium chloride compound, either pure or containing calcium chloride, and diluted with water, is admixed with a slight excess of hydrochloric acid or cupric chloride.  A quantity of calcium sulphate is also added to permit subsequent filtration. After filtration the product is dried and mixed with barium chloride which eliminates the soluble sulphates and in part remains unconverted.

Abstract: 947,181. Copy grinding; milling. LANDIS & GYR Ltd. May 18, 1961 [May 18, 1960], No. 17559/60. Headings B3D and B3K. In apparatus for machining by means of a rotary cutter or grinding-wheel the workpiece is able to be rotated and simultaneously moved at right angles to its axis of rotation in response to the radial movement of a follower in engagement with a rotary cam having a profile corresponding in shape to the shape which the finished product is intended to have, the cam follower is moved in a straight path by rotation of the cam and rooks a biased beam about a pivot, and a housing in which the workpiece to be machined is gripped bears on the beam and is moved thereby in a path parallel to that of the follower by movement of the follower, means being provided to rotate the workpiece at the same speed as that of the cam. A grinding machine attachment comprises a profile cam 2 mounted on a shaft 3 having a worm-wheel 5 meshing with a worm on a shaft 4 driven by a motor 6. The shaft 8 of a collettype chuck 9 holding a workpiece 10 is mounted in a housing 14 and has a worm-wheel 7 meshing with another worm on the shaft 4. The cam and workpiece revolve at the same speed. A follower 11 bears against the cam 2 so as to be moved up and down in a straight path by the cam. A beam 12 pivoted at 13 is biased by a tension spring acting on its outer end into contact with the follower 11 and with the housing 14, whereby the latter is moved up and down in guides 15 along a path parallel to that of the follower. The beam 12 has an alternative pivot hole 16 to give a different size ratio between the cam and the workpiece. The cam-engaging surface of the follower has a radius at least ten times that of the grinding wheel. To allow for the varying angularity of the shaft 4 the bearing blocks of each worm are mounted on a common slide 17 so that they can move to and from each other in a straight line, and the shaft 4 is split midway of its length, each part engaging and sliding on a square section 18. Each worm-wheel has mounted on its shaft a pulley, the two pulleys being of equal diameter and engaged by a belt under tension. The driving motor is preferably a pneumatic motor acting through a flexible coupling transferring rotary motion but not axial thrust. The motor exhaust is preferably directed on to that area of the workpiece engaged by the grinding wheel to remove swarf and to cool the workpiece. For machining a part of circular cross-section a pin is passed through a hole in the frame and a hole 19 in the beam. The housing may carry means for dressing the grinding wheel.

Abstract: 534,850. Liquid-raising apparatus. KNOX, G. S. June 16, 1939, No. 17667. Convention date, June 23, 1938. [Class 102(ii)] A gas lift pumping unit for oil or other wells comprises a valve 33 and port 45 for entry of the oil, a pipe 12 through which the oil is lifted to the surface, a gas pipe 14 and valve 21 having a smaller area exposed to the gas pressure than to the liquid pressure in the pipe 12 so that it opens when the ratio of the liquid to the gas pressure exceeds a pre-determined value and closes when if falls below this value A part of the upper face of the valve 21 is closed off by a metal bellows 18 filled with gas, e.g. at atmospheric pressure, if, e.g. it is desired that only a small difference of pressure in pipes 12, 14 will open but that a comparatively great difference is required for closing the valve 21, this is formed with a cylindrical extension 23, Fig. 12, coacting with a reduced bore 65 which causes a reduction, when the valve opens, of the gas pressure in the chamber 61 which acts on a portion 62 of the upper face of the valve 21. Preferably instead of or in addition to the valve 33 a spring closed oil valve 31, Fig. 3, is provided and is opened by gas from above the valve 21 passing through bores 25 into a small bellows 27 connected to a spring lifted plunger 30. When however the valve 21 opens and hence the pressure in the constricted space 24 falls the springs 32, 29 are sufficient to close the valve. The valve 31 may comprise a pilot 51, Fig. 5, which is opened first and controls a main valve 52 in the form of an annulus by causing a pressure drop. At one or more points above a packed joint 13, Fig. 1, and a port 15 which admits the compressed natural gas or air &c. supplied to the well casing 10 into the pipe 12 an auxiliary pump is provided comprising a valve 37 which is held shut by the gas pressure below it until a float 40, lifted by plug of rising oil until it engages a stop 42, is allowed to fall when the lifting gas reaches it and strikes a pin 39. When the wad of oil reaches the surface the pressure of gas above the valve 37 is reduced and the increased flow closes it. This pumping unit will operate against a back pressure, e.g. of a pressure gas trap or separator at the surface.
