Abstract: 1,175,501. Change-speed gear and control. TWIN DISC Inc. 5 Feb., 1968 [13 Feb., 1967], No. 5681/68. Heading F2D. A variable speed drive for a vehicle such as a tractor comprises constant mesh gearing providing four forward and reverse speeds selected by hydraulically operated duplex clutches, the hydraulic control system including a modulating valve influenced by a flow sensing valve for temporarily reducing the hydraulic pressure during a shift to produce gradual clutch engagement. Gearing.-An input shaft 1, Fig. 1, driven through a torque converter TC drives a gear 18 secured between the casings 6, 7 of a pair of clutches E 1 , Eg either of which may be operated to drive gears 20, 21 freely rotatable on the shaft. Gear 18 is in constant mesh with a gear (28) on a reverse shaft (2), gear 28 being secured to a pair of clutches (A 1 , A 2 ). The gears 20, 21 are in constant mesh respectively with gears 38, 42 on an intermediate shaft 3, freely rotatable reverse gears 30, (31) on the reverse shaft, which may be driven by clutches A 1 , A 2  respectively, also being in constant mesh with these gears, the gear 42 being splined to shaft 3 and gear 38 being secured to clutches S 1 , S 2  also splined to shaft 3 and operable to drive either of gears 40 and 41 freely rotatable on the shaft. Gears 40, 41 are in constant mesh with gears 52, 50 respectively on a pair of output stub shafts 46, 47 coupled to the front and rear wheels respectively of a tractor. Gear 50 is splined to shaft 47 whilst gear 51 is rotatable on shaft 46 but has external splines 53 engaging a shifting collar 54 which also engages splines 56 on shaft 47. As shown, a two wheel drive is provided through shaft 47 but collar 54 may be shifted to the right in the figure so that its splines also engage splines 57 on shaft 46 whereby a four wheel drive is provided through both shafts. Control system.-A pump P, Fig. 2, supplies hydraulic fluid to the clutches through manually operated speed and direction selecting valves SV, DV respectively. Fluid line 68 to the valves incorporates a flow sensing valve FS having a spring loaded spool 72 with a central orifice 77 through which fluid flows to the valves. On operation of a clutch, the rise in pressure shifts spool 72 to the right in the drawing against a stop 79 and opens a line 81 to the sump via an annular groove 73 in the spool and an orifice 82. Line 81 extends from a modulating valve MV connected to the fluid line and on being opened, releases the pressure in a cavity 84 behind a piston 84a, the resulting rightward movement of which fully uncovers a vent 84b and releases fluid in the supply line to a reservoir R. The pump pressure is therefore temporarily reduced and the ensuing gradual build-up of pressure caused by the return of spool 72, closing of line 81 and the return of piston 84a to close-off vent 84b, produces smooth clutch engagement. A brake-pressure operated dump valve 67 is provided.

Title: Polycaproamide filament yarn
Inventor: MIZUTANI SHIGERU
IPC: D02J1/22
Filed: 1969-02-03
Abstract: 1,234,872. Polycaproamide filaments. TORAY INDUSTRIES Inc. 3 Feb., 1969, No. 5787/69. Heading B5B. [Also in Division B8] A method for manufacturing an improved polycaproamide filament yarn comprises making the average moisture content of the yarn below 2À5% at the end of a drawing operation, and immediately after drawing sealing a package of the yarn in a bag made of material having a moisture permeability capable of keeping the average moisture content of the yarn below 2À5%. Thus the yarn may be heated during drawing to make its moisture content below 2À5%, or preferably below 2À0%. Such heating is suitably effected by winding the yarn around a heated roller at least five times. Alternatively, the yarn may be heated after drawing so as to make its moisture content below 2À5%. The bag for sealing the package is suitably made of a film of polypropylene, polyethylene, polyvinyl chloride or polyester. A variety of methods may be used. Thus a moisture content of from 4 to 6% may be bestowed on an undrawn nylon filament yarn, the yarn heated after or simultaneously with the drawing operation so as to make its moisture content less than 2À5%, and the yarn then taken up on to a package while being kept at the lowered moisture content and the package sealed in the bag. Alternatively, the package of the yarn may be placed within an air-conditioned cabinet (e.g. held at 25‹ C. and 75% relative humidity) made of a heat insulating material and provided with only a small slit for inserting the yarn and discharging it from the cabinet and delivering to the drawing stage. After being delivered from the cabinet the yarn is subjected to a drawing operation. The take-up roller of the drawing stage is suitably heated and the yarn wound around the roller several times, suitably at least five times, so as to evaporate excess moisture contained in the yarn. The yarn is then taken up on to a package and immediately thereafter sealed in the bag. The method is especially useful in the direct spinning and drawing process. In such processes, relatively easy and quick moisture absorption of the yarn being manufactured causes frequent yarn breakage during the warping operation in later weaving or knitting preparation steps. By using the method of the present invention in such processes, the number of yarn breakages in warping may be considerably reduced. A typical application in such a process comprises oiling suitably an undrawn filament yarn, drawing the oiled yarn by passing through drawing rollers which are heated so as to evaporate excess moisture contained in the yarn, taking up the drawn yarn on to a package and sealing the package immediately in the bag. Examples are given, in which a polypropylene bag is used, and drawing effected at 30‹ C. to 160‹ C.

Abstract: 287,519. Krupp Akt.-Ges., F. March 23, 1927, [Convention date]. Surface and outline gauges. - Comprises an internal thread gauge provided with two feeler pieces for engaging the thread movable relatively to one another at right angles to the longitudinal axis of the bodv to be tested and in the direction of the feeling bolt of an indicator to which the movement is transmitted against the influence of a spring or equivalent. One feeler piece b is fixed to and projects laterally from a frame a while a corresponding feeler piece c is fixed to a block f bored to receive a spring d against the influence of which the block f may shift relatively to the frame a. A bolt k fixed on the bottom of the frame a passes through the block f and engages the feeler bolt i of an indicator h carried by an extension of the block f. Upon pressing the hand lever e down the pieces b, c are moved together so that a nut to be tested can be slid over the threads on them the piece c being moved to engage the nut threads when the lever is released. If the indicator has been adjusted to a standard nut, deviations from the standard are readily seen. To test intermediate diameters of thread, the feeler pieces n, p are arranged as shown in Fig. 5 and provided with heads to correspond to the intermediate diameter enclosed in a centering sleeve v corresponding to the clear diameter of the piece to be tested. In this form the block f is moved by a lever q and slow motion eccentric r. The two different shapes of feeler pieces may be arranged on the same gauge so that the same instrument may be use for both purposes.
