Title: Improvements in or relating to drafting aprons for textile machinery
Inventor: WHITEHEAD KENNETH EDE
IPC: D01H5/74
Filed: 1952-06-17
Abstract: 708,166. Compound sheet material. ANDRE RUBBER CO., Ltd. June 17, 1952, No. 15224/52. Class 140 In a drafting apron for textile machinery consisting of an elastomeric material such as natural or synthetic rubber, the reinforcement, consisting of circumferential ties of continuous synthetic monofils or of non-twisted bundles of continuous synthetic monofils extending substantially parallel with one another circumferentially of the apron, is situated in a zone nearer the outer fibre-contacting surface than to the inner roller-contacting surface of the apron. The rubber of either or both layers of the apron may preferably be of the butadieneacrylonitrile copolymer type, and either layer may be compounded with or without carbon black; both layers may be compounded with suitable vulcanizing and accelerating agents and anti-oxidants. Preferably the monofils are of high tensile strength. Materials specified include regenerated cellulose and cellulose ester rayon, copolymers of vinyl chloride and vinyl acetate or cyanide or vinylidene chloride, polyurethanes and polyamides. As shown (Figs. 3 and 5) the drafting apron comprises a relatively thin outer fibre contacting layer of rubber 1 having a matte fibre working surface 4, a relatively thick inner roller contacting layer of rubber 2 and an interposed reinforcement layer 3 comprising single monofils 6 (Fig. 3) or untwisted bundles of monofils 7 (Fig. 5), preferably of nylon or perlon "U". The apron may be manufactured by wrapping a sheet of unvulcanised rubber preferably containing carbon black upon a mandril to form the layer 2, and scarf-jointing the meeting edges. Helical convolutions of the reinforcement may then be wound, with or without adhesive, upon the scarfed sheet. A further thin sheet of rubber, preferably free from carbon black, is then wrapped with or without adhesive round the convolutions and its meeting edges scarfjointed. The assembly may then be vulcanized and the outer surface ground smooth as necessary.

Title: An improved metering device for use in connection with milking machinery
IPC: A01J5/04
Filed: 1957-05-16
Abstract: 861,018. Measuring average and minimum values of a fluctuating pressure; indicating vibrations. PHILLIPS, E. M. May 16, 1957, No. 15605/57. Classes 106 (2) and 106 (4). A metering device (Fig. 1) for indicating the ratio of vacuum to air impulses in a pulsation line of a milking-machine installation has two chambers 10A, 10B interconnected by a restriction 14, chamber 10A being connected to the pulsation line through another restriction 13, and a pressure-gauge 17 in communication with chamber 10B. The effect of the restrictions 13, 14, is to damp out the pressure changes and so give an average value of the pressure on the gauge 17, which is calibrated to indicate the ratio of vacuum to air impulses. In a modification, Fig. 2, the restriction 14 is replaced by a non- return valve 21. Thus, as the pressure in chamber 10A falls, valve 21 opens, and the pressure in chamber 10B falls, but when the pressure in chamber 10A rises above that in chamber 10B, the valve 21 remains closed. So, after a short time, the pressure in chamber 10B will be equal to the minimum pressure in chamber 10A and this will vary with the number of impulses in a given time, if the ratio of vacuum to air is 1-1. In this case the pressure gauge 17 is calibrated in terms of the pulsation rate. A tap 22 is connected to the chamber 10B to enable the pressure therein to be returned to atmospheric after a test. In a modification, the passage linking the chambers divides into two alternative passages, the entrances to these being controlled by a twoposition manually-operated tap, one passage containing the restriction 14 and the other containing the non-return valve 21. In this case the gauge 17 is calibrated in terms both of the rate and the ratio.
