Title: An improved method and apparatus for testing thermosetting plastic materials
IPC: G01N11/02
Filed: 1934-01-31
Abstract: 432,646. Testing thermosetting plastic materials. BAKELITE, Ltd., 68, Victoria Street, Westminster.-(Bakelite Corporation ; 247, Park Avenue, New York, U.S.A.) Jan. 31, 1934, No. 3276. [Class 106 (ii)] Thermosetting plastic materials arc tested by subjecting a predetermined quantity of the material to heat and pressure in a mould provided with a channel along which the material may flow maintaining heat and pressure until the material sets, and measuring the extent and /or rate of flow along the channel. Formed in a heavy frame 52 is the moulding chamber 50 in which the ram 2 has a sliding fit. The upper end of the chamber is closed by a coned block 38 which may be made in two sections and is formed with a channel 8 much smaller in diameter than the chamber 50. The block is driven tightly into the seating 44 and held in place by a strap 40 and bolts 42. Holes are formed in the block to receive a thermometer. Both block and chamber are heated by steam, as is also the hollow ram 2. The latter is mounted on a support 20 sliding in a base 22 and attached to a crossbar 24 from which chains 26 pass over pulleys 28 to a lower crossbar 30, from the centre of which weights 4 are suspended. The tip 54 of a follower 10 has a sliding fit in the channel 8. The follower passes through a guide yoke 56 and is provided with a shoulder 60 and adjustable collar 58 to limit up and down movement. A rod 62 slidable in a guide 64 rests on the follower 10 and carries a weight 66 to afford a counter pressure. A pair of pulleys 68, 70 on same spindle are connected by chains 72, 74 with the rod 62 and recording stylus respectively. The support 80 and associated parts may be tilted about the pivot 82 to disconnect the recording mechanism. This comprises a chart drum 89 driven through a clutch 88, 84 from a spring motor. In use, the temperature is adjusted and the required weights 4 applied. The ram 2 is now drawn down through pinion and rack mechanism by turning the handle 34 and is held down by inserting a pin 36 in its hole. The clutch 88, 84 is now engaged until the stylus rests on a convenient line of the chart and the trigger 96 of the stylus engaged with the end 94 of the clutch lever to hold the latter disengaged. A tablet 6 of test material is now placed on the ram 2 and the pin 36 withdrawn. The tablet is raised and the tip 54 moved back until flush with the bottom of the channel 8. This initial movement releases the trigger 96 when the chart moves and the test really begins. Material flows into the channel 8 until hardened sufficiently to withstand pressure. A curve of extent of flow against time is recorded.

Title: Improvements relating to the spinning of textile yarns
Inventor: ARMITAGE ALAN RALPH
IPC: D01H5/36
Filed: 1956-02-02
Abstract: 832,616. Spinning textile yarns; fabrics. ARMITAGE & RIGBY Ltd. April 24, 1957 Feb. 2, 1956], No. 3298/56. Classes 120(2), 120(3) and 142(4) [Also in Group XXXVII] In spinning textile yarns, the count and twist are both varied automatically during spinning by varying at least two of the following: the speed of the spindles, the speed of the front drafting-rollers and the speed of the rear drafting rollers, each speed so varied being varied in such a way as to maintain a selected relationship between the count and the twist. The variations may be instantaneous or gradual and may be made at regular or irregular intervals and by electrical or mechanical means. The changes of count and twist produced in this way give a random or pattern effect in fabrics made from the yarn. In the preferred form, in which the relationship is according to the expression T=K#C the spindles 5, Fig. 1 of a ring-frame are driven through the tin rollers 4 from a constant speed motor 1, and the drafting rollers are driven by variable speed motors 8, 17. The motor 8 drives the shafts 14, 16 of both sets of front rollers through a wheel 10, in the one case through a gear 11 and chain 13, and in the other through reversing-gearing 12, 15. The other motor 17 drives the shafts 23, 26 of the back rollers through a reduction unit 18 and a chain 19, in the one case through a gear 20 and a chain 22 and in the other case through reversing gearing 21, 24 and a chain 25. A punched tape, punched cards or magnetic storages in a reader CR operates, according to a pre-arranged programme, relays in a cubicle &c. RC to switch in or out of circuit a selection from a number of potentiometers in selectors SS to vary, through motor controllers MC, the voltages applied to the armatures of motors M1, M2 driving the drafting rollers. The punched tape &c. determines also the periods for which particular speeds are operative, through cams driven by a synchronous motor and brought into operation by magnetic clutch means controlled by the signals from the tape &c. The tape may embody a 5-column code, each column representing a particular voltage and alternate rows across the tape representing the intervals for which the voltage selected by the previous row is to operate. Each potentiometer can be pre-set to correspond to a selected speed and whenever a relay is made operative it is locked in and the others rendered inoperative. Each relay cubicle may control a number of selectors SS and each selector may feed up to four motor controllers MC. To ensure that the twist/count relationship is maintained despite the inertia of the spindles during stopping and starting and that spindles and drafting rollers come to a stop together, the motor 1 has a generator 27 feeding current to the field windings of the motors 8, 17. Alternatively, an electronic timer may be used to delay the switching-off of the motors 8, 17.

Title: Improvements in and relating to multicylinder heavy oil engines
IPC: F02D17/02
Filed: 1926-02-05
Abstract: 251,238. Brown, E. April 27, 1925, [Convention date]. Regulating delivery by opening suction valves, and by bye-passes.-In multicylinder oil engines required to operate for long periods at greatly reduced powers, such as marine engines working at low cruising speeds, a greater efficiency during such periods is obtained by regulating the fuel pumps so as to suppress the fuel injections for every other power stroke, or for two out of every three or other ratio of the power strokes successively throughout the whole or a number of the cylinders. or, in the case of double-acting engines, of the combustion chambers. Fig. 13 shows means for controlling the fuel injections produced by a pump comprising a plunger 63 actuated by a cam 60 so as to draw oil through a suction valve 64 and discharge it through a conduit 66 to the injection valve. When injections are to be suppressed, a cam 75 is moved axially, or vertically about the centre 81, into engagement with a plunger 77 so as to hold open the suction valve 64 at every alternate or other number of power strokes. The regulation of the amount of fuel injected is obtained by means of levers 67, 68, 69 which open to a greater or less extent a by-pass valve 71, and the cam 75 may be arranged to act on this by-pass valve instead of upon the suction valve. The Specification as open to inspection under Sect. 91 (3) (a) also describes the following subject-matter, which does not appear in the Specification as accepted. A modification of fuel pump is provided with two sets of cams, one cutting out alternate injections, and the other two out of three injections, which are brought into action automatically at the appropriate speeds by a hydraulic relay controlled by a governor driven from the propeller shaft of a ship. The governor may also actuate the lever 69 to control the amount of fuel injected.

Abstract: 908,671. Friction clutches. REGIE NATIONALE DES USINES RENAULT. Feb. 2, 1959 [Feb. 18, 1958], No. 3611/59. Class 80 (2). To oppose the effect of centrifugal force acting upon a mass of fluid introduced under pressure into a space 7 to engage a clutch and tending to increase the force engaging the clutch, centrifugal masses 19c are formed on extensions of levers 19 through which the clutch engaging force is transmitted to a presser plate 20. The levers 19 pivot on pins 18 fast with a driving clutch housing 8 and engage between a plate 14, axially slidable upon a hub 12, and the presser plate 20, to increase the clutch engaging force applied by the fluid under pressure. Springs 16 bias the plate 14 to the disengaged position, and springs 21 bias the presser plate 20 to the disengaged position. The space 7, to which pressure fluid is introduced through passages 4 . . . 6, is formed on one side by the rotating clutch housing 8 and on the other side by a diaphragm 9 clamped thereto. The size of the masses 19c may be so selected as to exactly negative the effect of centrifugal force acting upon the mass of fluid in the space 7, in order that the clutch engaging force may be constant irrespective of the speed of rotation, or alternatively, the size of the masses 19c may be increased, so that at high speeds, the clutch engaging force is partly relieved; in this form, the clutch may be combined with an hydrodynamic torque converter, the torque which can be transmitted through the clutch being reduced at high speeds when the torque transmitted through the converter is correspondingly reduced by the high speed of operation.
