Abstract: 1,008,554. Endless elevators for articles. H. M. SAWRIE. Nov. 3, 1961, No. 39456/61. Heading B8A. As shown in Figs. 1 and 5 a continuous lift comprises two pairs of chains 5, 6 and 21, 22 with platforms 31 supported by flat bars 36, 37 connected between the chains. Platform chains 31A, 31B have bar segments 42 to prevent the bending of the platform when horizontal, the load B being carried by rods 44 connected between links 40 of the platform chains. At the top of its travel each platform 31 changes direction from vertical to horizontal discharging its load B on to a take-off conveyer 73 and, by virtue of its platform chains fold flat into the plane defined by the descending flights of chains 5 and 6. A load B may be fed from a conveyer 60 on to a treadmill 55 comprising rollers 56 and is held by a stop 61 to await collection by a platform 31. The lift and treadmill are synchronized so that the platform rods 44 mesh with the treadmill rollers 56 and are thus able to pass beneath the load B prior to changing direction vertically to lift the load. In a modification as shown in Fig. 5, the treadmill is replaced by fixed stub rollers 72 and the platform is of double cantilever form.

Title: A method for the high-speed extrusion of polypropylene
IPC: D01F6/04
Filed: 1965-09-20
Abstract: 1,073,264. Melt spinning isotactic polypropylene. J. UI. Sept. 20, 1965, No. 40044/65. Heading B5B. Isotactic polypropylene is melt spun at a shear rate within the range extending from the shear rate at which the filaments formed no longer exhibit primary melt fracture to the shear rate at which they exhibit secondary melt fracture. When a high molecular weight polymer is melt spun at a shear rate exceeding a certain limit the filaments produced have a rough surface. This phenomenon is termed " primary melt fracture ". In the case of isotactic polypropylene, if the polymer is extruded at a shear rate much above that at which " primary melt fracture " first occurs and at a temperature which exceeds the melting point of the polymer but is lower than the melt spinning temperature normally employed, e.g. below 200‹ C., the extrudate no longer exhibits melt fracture. Further increase in the shear rate of extrusion however results in the extrudate again exhibiting melt fracture. This subsequently occurring melt fracture is termed " secondary melt fracture ". The polymer may be extruded at a temperature which is above but not more than 50‹ C. above its melting point. The polymer may be extruded at a shear rate in the range of 1 x 10<SP>2</SP> to 1 x 10<SP>4</SP> see. It may be extruded through a nozzle or nozzles having a diameter of 0À5 to 2À0 mm., a length more than five times the diameter and an inlet duct in the form of a truncated cone the apical angle of which may be zero.

Abstract: 1,071,220. Milling; grinding. CARL HURTH MASCHINEN UND ZAHNRADFABRIK. Oct. 6, 1964 [Oct. 9, 1963], No. 40670/64. Headings B3B, B3D and B3K. A machine tool for cutting or grinding a two-sided groove (such as a key-way) comprises a crank mechanism 19, 22 for feeding the tool along the groove, a steplessly variable drive 32 for modifying the quasi-sinusoidal motion of the crank drive by varying the speed of input to the crank mechanism, and means 74 for enabling the tool to be displaced transversely after making a cut. The work 9 is clamped on a slide 12 mounted on a slide 5 carried on a vertically-movable knee 3. The belt-driven tool 16 is carried in an axially-movable sleeve 17 in a slide 15. The slide 15 is reciprocated by the adjustable crank 19, Fig. 4, rotated by a motor 38 through the steplessly-variable gearing 32, belt or change-speed gearing 48 to 58, and a worm 24, the gearing being continuously adjusted by a cam 36 and a lever 35 to produce a substantially constant speed of the slide. A further crank 67 rotates linkage 69, 71 to oscillate a pawl 73 which rotates a ratchet 74 to feed the work towards the tool. A clutch 82 transmits the rotation of the ratchet 73 or of a worm wheel 85 to a screw 80 which feeds the slide 5. The worm wheel 85 is rotated by an electric motor to enable a rapid return motion or a drilling feed to depth to be effected. The screw may also be rotated manually and the pawl 73 may be lifted clear by power means. Cams 88, 89, 91, 92, 93 operate hydraulic or electrical control means. The work can be fed vertically by rotating a screw 114 by an hydraulic or electric motor. Alternatively, a cam 108 is rotated by a motor 117 to move a lever upon which the end of the screw 114 rests. The fulcrum of the lever 106 may be adjusted manually or automatically by a motor applied to a connection 102a thus - enabling a conical key-way to be cut or wear of a grinding wheel to be compensated. Adjustment of the fulcrum also determines the width of slot to be cut. In operation, the work is fed into the cutter to drill the end of the slot centrally, the cutter is traversed the length of the slot to take a rough cut, the work is then raised or lowered and, on a return tool traverse, one side of the slot is finished. Finally, the work is moved in the opposite direction and the other wall is finished. More than one finishing cut may be made with in-feed between cuts. Since the cutter is moving while the work is raised or lowered, the end of the slot is curved. In a modification, the tool is mounted in a planetary carrier so that it can be moved in a circular path to machine the end of a slot. Further modifications include processes in which the centre of the slot is milled to depth in several passes and the sides are each finished in a single pass, or one side of a slot is first milled and then the other.

Title: Semi conductor translating devices and apparatus
IPC: H01L29/02
Filed: 1959-12-02
Abstract: 941,368. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Dec. 2,1959 [Dec. 11, 1958], No. 40899/59. Heading H1K. A semi-conductor device comprises P and N type zones each provided with a spaced pair of low resistance contacts and forming a PN junction. A typical device (Fig. 2) is made from a slice of 20 ohm. cm. P-type silicon by coating with a solution of phosphorous pentoxide in ethylene glycol monomethyl ether, heating for 12 hours at 1300 ‹ C. to produce surface N-type layers 0.0028 inch thick and then lapping one surface down to a thickness of 0.0056 inch. After coating the P-type surface with a solution of boron chloride and heating to 1000 ‹ C. for an hour to provide a good contact surface, both surfaces are plated with gold, and the wafer cut into circular discs. Annular trenches 14, 15 are cut in the faces of the discs to within 0.0013 inch of the junction and after etching the N surface flat headed gold wires 21-24 are compression bonded to the central and peripheral gold layers on each face. The N and P faces are then separately etched chemically to bring the resistance of the narrow annular regions to an optimum value. In an alternative annular P and N-type annular zones formed by diffusion into the disc replace the trenches 14, 15, respectively. When connected as shown, schematically in Fig. 3, such a device functions as a voltage controlled resistor. The N and P regions are connected in parallel in an alternating signal current circuit. The bias 43, by controlling the extent of the depletion layers, which is independent of the signal current amplitude, determines the resistance of the zones. The signal current amplitude is not limited by the junction breakdown voltage nor is the frequency response affected by the junction capacitance which is not in the signal current circuit. In another application in which electrodes 31, 34 are used as input and output and electrodes 32, 33 are interconnected the device operates as a negative resistance element. If, on the other hand, electrodes 32, 34 are both earthed and electrodes 31, 33 so biased that the junction is reverse biased and current flows in opposite directions in the N and P zones the device functions as a transformer. In a further application as an impedance inverter or gyrator (Fig. 7) the biasing arrangements are such that the junction is reverse biased and the currents in the N and P regions flow in the same direction. Specifications 748,487 and 896,246 are referred to.
