Title: Ring spinning test machine
IPC: D01H1/02
Filed: 1968-01-29
Abstract: 1,215,832. Ring frame. TEXTILE & ALLIED INDUSTRIES RESEARCH ORGANISATION. 29 Jan., 1968 [28 Jan., 1967], No. 4490/68. Heading D1D. In a ring spinning machine the reciprocating building motion originating at a cam 42 is transmitted to the ring rail 69 via spring loaded, telescopic arrangement 61, 62, 63 whereby the rail is pulled down, e.g. by a chain 60 against the action of the spring and lifted by the spring when the chain is released, means being provided to superimpose a progressive lift on the reciprocating motion. As shown, cam 42 rocks a lever 44 to which a chain 49 is attached to transmit the motion. Chain 49 passes about a jockey roller (50b) see Fig. 2 not shown which is mounted on a threaded shaft (96) rotated by a ratchet wheel indexed by a lever 90 connected to lever 44; thus chain 49 is progressively "paid out" during the build and the lift provided. The machine is provided with a high degree of adjustability to make it suitable for testing. The spindles 68 are driven from pulleys 105 on a main shaft 6 driven from a motor 2 via an opposed core pulley variable speed arrangement 5a, 5b, 5c, 5d. The ring rail 69 is provided with large ring receiving apertures and adapters to mount different sized rings. The builder motion lever 44 is provided with adjustable pivot and the link 90 therefrom which operates the ratchet mechanism of the pick motion is adjustable in a slot in the lever. The ratchet may be provided with a shield so as to shield an adjustable number of ratchet teeth from the pawl. Different lengths of spindles may be fitted on the spindle rail and to accommodate different spindles the drafting mechanisms are mounted to be vertically and horizontally adjustable by handwheels, The tilt of the drafting mechanisms may also be adjusted. The lappet rail is arranged to be traversed with the ring rails and the height of the lappet rail is adjustable. The block (100) Fig. 2 not shown which carries the jockey pulley and is moved to provide the gain is arranged to operate a limit switch (LS) which stops motor 2 when the bobbins are full. To reset the gain mechanism for a fresh wind the ratchet pawl is lifted by an eccentric and the jockey pulley wound back to its starting position by a handle (99). The machine may be movable on castors (1b).

Title: Improvements in or relating to propellers

Filed: 1943-03-19
Abstract: 578,998. Screw propellers. MILNER, H. L. March 19, 1943, No. 4531. Drawings to Specification. [Class 114] The blades of an airscrew or marine propeller are each set at such an angle relatively to the basic pitch angle that the torque force of the blade is substantially the same as that of a datum blade, whereby the propeller is dynamically balanced. The variation in the angular position of the zero-lift line from that of the datum blade is first measured at various positions along the blade, e.g. by means of the gauge described in Specification 578,994. From the data thus obtained the variations in torque force are calculated and the pitch angle, at which the blade should be set to make the forque force substantially the same as that of the datum blade, estimated. In another method a blade pitch setting is also calculated by the same method in order that the thrust moment may be the same as that of the datum blade and the blade is finally set either at this angle or the torque angle or at some intermediate value. Specification 578,993 also is referred to.

Title: Process for the preparation of an aqueous suspension of finely-divided water-insoluble silicates capable of cation exchange
IPC: B01J39/10
Filed: 1977-02-04
Abstract: An aqueous suspension, suitable for further processing in detergents and cleaning agents, of a water-insoluble silicate of the general formula I: (Cat2O)0.8-1.3.(Al2O3).(SiO2)1.75-2.0 (I> in which Cat is an alkali metal cation, is obtained by mixing alkali metal aluminate dissolved in water with alkali metal silicate dissolved in water in the presence of excess alkali. In order to meet the requirement for a process which, in a particularly short reaction time and with a high space-time yield, produces aluminium silicates of the abovementioned formula, which are extremely finely particulate but at the same time have a narrow particle size spectrum, the aqueous solutions, whose arithmetic overall composition in terms of their Al2O3 and their SiO2 content corresponds to the abovementioned formula, but which in total have at least 2.5 mol of Cat2O per mole of Al2O3 and at most 80 mol of water per mole of Al2O3 of the formula, are mixed rapidly and with vigorous stirring and the suspension obtained - before the solutions have been combined completely, if appropriate - is passed at least once - and at least for as long as the solutions have not been completely mixed - through a size reduction appliance.
