Abstract: 1,207,202. Injection moulding. ECKERT & ZIEGLER G.m.b.H. 24 April, 1968 [7 June, 1967], No. 19359/68. Heading B5A. [Also in Division F1] A floating piston 5, 6 is movable through an adjustable stroke in a closed cylinder 4, thereby to displace a predetermined volume of hydraulic fluid from a chamber 9 through a line 15 to a cylinder chamber 14 and thus cause proportional displacement of a piston 2 operating the ejecting device of a moulding machine. The stroke of the piston 5, 6, and consequently the piston 2, is adjusted by a setting pin 11 screwed into the cylinder 4 and locked by a sleeve 12. To move the floating piston 5, 6 to the right, a valve 19 is operated to cause pressurization of a line 22. Movement of the piston 5, 6 expels fluid from an annular space 8 in the cylinder 4 through a non-return valve 26 and lines 27, 28, 24 to a tank 21. Reversal of the valve 19 pressurizes the line 24 to return the piston 2. At the end of the return stroke, the resulting pressure build-up in the line 28 opens a valve 25 thereby connecting the annular space 8 to pressure and ensuring the complete return of the piston 5, 6. Leakage from the chambers 9, 14 and the line 15 is made-up through a line 16 including a non-return valve 17.

The internal friction of a wire (7), Fig. 1 (not shown), is measured in terms of the energy input required to maintain oscillations of a torsional pendulum the spindle (2) of which is attached to the wire, and carries four arms 3, 4, 5, 6, Fig. 2, the said energy input being controlled by any departure of the amplitude of pendulum oscillation from a required value as detected by pairs of capacitors 20, 21 and 22, 23 which vary the frequencies of respective oscillators 26, 25. The frequency excursions produced in the two oscillators are equal and opposite, and these frequencies individually beat with a reference frequency 31 in a frequency changer 30, the outputs of which are fed to a discriminator 32 which compares the frequencies, and a differential amplifier 37 which receives at 35, 36 a voltage having an amplitude proportional to the difference between the two frequencies. A memory device 40 is provided with the amplifier 37 to store a voltage appearing at 35, 36 for one cycle of the pendulum oscillation, whereby the amplitude of successive oscillations are compared and any difference in amplitude used to control the energy supplied from terminals 42, 43 to coils 16 to 19 which act upon magnets 14, 15 carried by two arms of the pendulum. A meter 48 indicates the energy supplied. The enclosure 8, 9 may be heated to measure the temperature dependence of the internal friction, and the frequency of the pendulum oscillation may be measured to give the Young's modulus of the wire.

A method of coating a hydrophilic sheet material comprises applying an aqueous dispersion of a coalescable coating composition to one surface of the material and passing the coated material through a path whilst supported on the uncoated surface to prevent curling of the edges, the path being long enough to coalesce the coating, applying an aqueous dispersion of a coalescable coating composition to the second surface of the sheet material and passing the coated material through a second path whilst supported on the first coated side, the path being long enough to coalesce the coating, and then drying the coated material. The coating composition is preferably an aqueous dispersion containing 33.3% by weight of solids, and may be a dispersion of a copolymer of vinylidene chloride with one or more copolymerisable monomers. in which the vinylidene chloride content exceeds 85% by weight. The hydrophilic sheet material may be regenerated cellulose film, hydroxyethyl cellulose film, carboxymethyl cellulose film, cellulose ether film or paper. In apparatus for carrying out the method, the aqueous coating composition is applied by means of a roller dipping into a trough containing the composition, and the applied coating is doctored by means of an air-knife. Each path through which the material passes subsequent to the coating operation comprises a series -of spaced rotatable guide rollers arranged on the line of an arc. Spreading rollers may be arranged between the guide rollers. The coated. material is dried by passage through a hotair dryer, the material passing vertically upwards and downwards through the dryer whilst hot air is directed symmetrically at both surfaces.

Filed: 1936-07-17
Abstract: 463,768. Friction clutches. BORG & BECK CO., Ltd. July 17, 1936, No. 19908. Convention date, March 2. [Class 80 (ii)] A steel clutch disc 3 has its peripheral portion slotted to form two concentric sets of circumferentially - extending flexible wings 5 and 6 bent out of the plane of the disc. The wings of the two sets extend in opposite directions and are tapered towards their ends. The outer ends of the wings 6 are curved back towards the disc. One friction facing 7 is secured to the middle of the wings 6 by rivets 12, while the other facing 8 is secured to the back of the disc by rivets 11. The outer ends of the wings 5 contact with the facing 7 at all times, these wings acting as cantilever supports. The outer ends of the wings 6 may contact with the facing 8 at all times, these wings then acting continuously as semi-elliptic supports. Alternatively, the outer ends of the wings 6 may, in the disengaged condition of the clutch, be spaced slightly from the facing 8. During clutch engagement, the wings 6 act in this case initially as cantilever supports and finally as semi-elliptic supports, thus giving a two-stage cushioning action. Openings 14 may be formed in the wings 6 to increase their flexibility.
