Title: Gear drives of cyclically varying angular velocity output and  a method of obtaining their pitchline profile geometries
IPC: F16H55/08
Filed: 1973-01-11
Abstract: 1418161 Toothed gearing HALLDEN MACHINE CO 11 Jan 1973 1457/73 Heading F2Q A pair of meshing gears 10, 12 producing a cyclicly varying output speed from a constant input speed have each symmetrical half of each gear constructed with the pitchline formed of pairs of successive curves of which the curves of each pair (two pairs as shown) have different polar equations. As shown for gear 10 one half of the gear is formed by curves c 1 , c 1 <SP>1</SP> and c 1 <SP>11</SP>, having junctions at points j 1  and j 2 , the curve c 1  giving the desired variation in output speed as it meshes with the teeth of curve c 2  of gear 12, the output gear. The curves c 1 <SP>1</SP> and c 1 <SP>11</SP> and the corresponding curves c 1 <SP>1</SP> and c 2 <SP>11</SP> of gear 12 are chosen so that the formation of a node or a cusp is prevented where the angle # 1  or # 2  is zero or 180 degrees. The values of the radius r 1  or r 2  of the gears for all values of # 1  and # 2  is found by first setting up the polar equations for the curves and then solving them knowing the centre to centre distance g between the gears (constant throughout rotation) and using the facts that the gears (in the embodiment shown) have equal perimeters, and at each point j 1  and j 2  the curves have equal angles of obliquity, angular velocities, radius and known angle 0. Balance gears 30, 32 for the gears 10, 12 can also be constructed using a known relation: (r 1 /r 2 )<SP>2</SP> + x<SP>2</SP>(r 2 /r 4 )<SP>2</SP> = Z in which r 3  and r 4  are the radii of the balance gears 30, 32 and x and z are constants which can be determined. The balance gear 30 is mounted on the same shaft as driving gear 10. True dynamic balance is only achieved over the curve portions c 1  and c 2 . In an alternative embodiment the driving gear has twice the perimeter of the driven gear (Fig. 8, not shown), with the driving gear having two perpendicular axes of symmetry, each quadrant mating with a symmetrical half of the driven gear. There may be more than three curves in each half of each gear.

IPC: H01L21/16
Filed: 1928-01-19
Abstract: 283,901. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Slepian, J.). Jan. 19, 1927, [Convention date]. Static contact rectifiers, arrangement of. - In rectifiers of the type utilizing the asymmetric conducting property of the junction between a metal body and a metallic compound formed thereon, a neutral contact with the layer of compound is obtained by subjecting a part of the layer to electrolytic reduction. For example copper discs 1 are heated to temperatures between 500‹ C. and the melting point of copper in an oxidizing atmosphere until a layer 2 of cuprous oxide surrounded by a layer 3 of cupric oxide is formed thereon. The oxide layers are then removed from one side and the inner edge of each disc, and the discs are mounted in pairs as shown in Fig. 5 on a conducting arbor 6 in a bath containing an electrolyte such as dilute sulphuric acid, sodium hydroxide, potassium fluoride, or ammonium chlorate solution. Graphite electrodes 10 are mounted on insulating collars 8 between each pair of discs, and connections are made between the arbor 6 and the electrodes 10 to a source of current. Either D.C. or A.C. may be used since in the latter case, the asymmetric conducting property between the oxide and copper serves to ensure that current will flow only in a direction to cause reduction of the outer surface of the oxide layer to metallic copper. Preferably A.C. is used for the first minute, and then D.C. at a lower current density for a further fifteen minutes. A number of treated discs consisting of the original copper, a cuprous oxide layer, and a layer of reduced copper are then mounted on an insulated bolt to form a rectifier, or two sets of discs connected in opposition may be used to form a condenser. Specification 277,684 is referred to.

Filed: 1946-01-21
Abstract: 626,849. Wood forms; veneering. LEINO, E. M. Jan. 21, 1946, No. 2010. Convention date, May 19, 1945, [Classes 145(i) and 145 (ii)] Uneven wooden plates are finished by a method in which the work-piece is fed through a machine slot the width of which corresponds to the desired thickness of the work-piece the one side of the machine slot being formed of a support base and the other of the shearing line created by the cutting edges of one or more cutter blades stiffly supported but vertically adjustable with regard to the support base, performing the finishing movement, which direction is parallel with the support base and forms an angle with the direction of feed, while the workpiece is bent and pressed tightly against the support base by pressers on one or both sides of the cutter irons in such a manner that no shearing line or its tangent will touch the point of contact between the nearest presser and the work-piece. Referring to Figs. 1 and 2 a large toothed cutter disc 1 revolves around axle 2 which is parallel with the feed direction. Workpiece 5 rests on a support base 3 with a curved working surface, this base sliding in guides 4. Pressers 6 are fixed tightly on both sides of the cutting disc. The finishing slot 7 between support base and disc can be carved either with the permanent teeth of the disc itself or with special toothpieces temporarily fastened to the disc edge and extending beyond the points of the permanent teeth. Then the support base is moved to the other end position, the workpiece placed on it, and both fed past the rotating disc which finishes the work-piece smooth. In the modification of Figs. 3 and 4 several narrow cutting discs 1 are fitted to a common axle 2 at set intervals, the axle being at an oblique angle to the feed direction and pressers 6 are placed both between and on the sides of the cutter discs. Figs. 5 and 6 show a modification where the the cutter disc is a short cylindrical piece that rotates around its axle 2 fitted at right angles to the flat surface of base 3. The modification of Figs. 7 and 8 depicts a cutting mechanism made up of several straight blades 1 moving in a straight line and placed at an angle to both opposite feed directions. For use on a curved support base the support base and cutter are so fitted that they are adjustable both horizontally and vertically whereas for a flat working surface only vertical adjustment is necessary. For work-pieces which resist bending e.g. plywood a fixed short support base along which the work-piece glides through the finishing slot e.g. by means of feeding rolls is used.

Abstract: 723,299. Wrenches. GOULD, J. P. E. April 6, 1951. No. 2032/53. Divided out of 723,209 [Group XXVIII]. Class 61. Apparatus for coupling or removing a screw closure connection 16 from an oil well head 11 or other vessel while under fluid pressure comprises a flow control valve C detachably screwed onto external threads on the tubular base A which communicates with the head 11, and a tool D releasably carried by the flow control C. The flow control C has openings 46, 47 at each end and a seat 48 for a plug 49 which has a transverse opening 50 and can be rotated by a handle 51 to establish an opening in communication with the base A. The tool D comprises a closed chamber in a housing threaded at 61 for engagement in the opening 47 of the flow control valve and a shiftable member insertable through the opening 50 in the plug 49 into coupled engagement with the screw closure 26 and retractable to withdraw the closure from the base A through the plug valve. The shiftable member comprises a rod 63 slidable in the end closure 62 of the chamber, the outer end of the rod being secured to a head 66 provided with handles 78. The head is attached to a sleeve 67 surrounding the housing and is sealed against the housing and closure member 62 respectively by packing. Between the packings the outer diameter of the housing is less than the inner diameter of the sleeve 67 to provide an annular chamber the length of which varies according to the position of the sleeve 67, ports being provided to connect the chamber with the interior of the housing. The coupling member comprises a stem 93 having a sleeve 90 by which it is adjustably fixed to the rod 63 by a set screw. A wrench socket 94 to fit the polygonal end 26 of the closure is.provided at the end of the stem 93. A guide element 95 having a spring detent 96 engages within the bore 37 and holds the socket in engagement with the closure. The stem 93 is of less diameter than the diameter of the interior of the housing to provide communication between the interior of the housing and the plug opening 50. As soon as the seal between the screw closure member 26 and tubular base is broken the pressure fluid in the member 11 flows into the housing and through one of the ports into the annular chamber thus causing the rod 63 to move longitudinally.
