Filed: 1944-09-25
Abstract: 594,886. Speed governors. CHILMAN, J. A., MAPP, A. G., MORRIS, E. H., and ROTOL, Ltd. Sept. 25, 1944, No. 18302. [Class 57] [Also in Group XXXV] In a synchronizing and speed control for engines driving propellers of a multi-engined aircraft, and of the kind described in Specification 515,934, automatic means adjust to a predetermined value the length of the operating member connecting the pilots manual constant speed control lever with the means varying the loading of the speed governor spring whenever the synchronizing control is not operating. When the synchronizing control is switched off and stator winding of each electrical differential, normally responsive to the difference between the speeds of master and slave engines, is short-circuited, the remaining stator winding is connected through a reversing switch 36 which is operated by a follower 35 and cam 30 driven by the rotor shaft 20 and capable of continuous rotation. The cam 30 is mounted on a shaft 21 on one end of which is a crank-pin 22 which, in one construction, is linked to a lever 24 pivoted on a radius arm 26 ; the pilots control lever is connected through points 28 and 29 on the lever 24. When the synchronizing control is inoperative the rotor will revolve in a direction depending on the position of cam 30 until the reversing switch is in its off position, determining the effective length of the pilot's control connection. When applied to a hydraulic system the crank-pin 22 determines the amount of fluid in the connection.

Title: Antenna commutating arrangements

Abstract: 1323278 Radio navigation; aerials MARCONI CO Ltd 20 April 1972 [20 April 1971] 18370/72 Headings H4A and H4D An aerial commutating arrangement such as is used for a Doppler V.H.F. omni-range system, and in which the movement of an aerial around a circle is simulated by sequentially activating the fixed elements of a circular array, features the division of the elements into two groups each occupying a semi-circle, and each having a respective group distributer, to which the elements are connected via individual switches, and to which either upper or low side-band R.F. power is fed via a changeover switch. As described a circular array comprises 48 elements. The odd-numbered elements 1, 3, 5, ... 23 occupying one semi-circle are connected via switches to a group distributer 51, which is also connected to a changeover switch 53. The odd-numbered elements 25, 27, 29, ... 47 occupying the other semi-circle are connected via switches to a group distributer 52, which is also connected to the changeover switch 53. A switch is also provided for each element so that it may be earthed when not in use, to prevent interaction with radiating elements. In the Figure, the switch 53 is positioned to supply LSB power to the distributer 51 and USB power to the distributer 52. The element 3 is connected to the distributer 51 and the diametrically opposite element 27 is connected to the distributer 52, all other elements being earthed. Sequential switching takes place so that the simulated rotation takes place in onethirtieth of a second, the next pair of odd elements to be activated being nos. 5 and 29, when nos. 3 and 27 are disconnected from the distributers, and are earthed. When the elements 25 and 1 are to be activated, following the elements 23 and 47, the switch 23 changes over, so that USB power is supplied to the distributer 51, and LSB power is supplied to the distributer 52. The element 1 may lie substantially in the direction of magnetic north with respect to the centre of the array. A similar arrangement is provided for the evennumbered elements of the array, but in order more closely to simulate the rotation of a radiating aerial at constant speed and to reduce amplitude modulation caused by the switching operation, bursts of energy from adjacent elements are arranged to overlap in time by half the burst period. That is, sideband energy is switched directly between consecutive oddnumbered elements (1, 3, 5,...) and is concurrently, but displaced in phase by half a burst period, switched between consecutive even-numbered elements (2, 4, 6 ...).

Title: Improvements in or relating to the production of cellulose derivative compositions
IPC: C08L1/28
Filed: 1938-06-21
Abstract: 516,145. Cellulose derivative compositions. HOUGHTON, A. A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 21, 1938, No. 18467. [Class 2 (ii)] Cellulose derivative or conversion product compositions are obtained by subjecting an insoluble effect material to a mechanical dispersing operation while in contact with a comminuted water-wet cellulose derivative or conversion product which is soluble in cold water, but not in hot water, the mechanical treatment being effected at such a temperature that the cellulose derivative remains undissolved, and then cooling the resultant mixture to ordinary temperatures in the presence of sufficient water to ensure solution of the cellulose derivative. The mechanical operation may be conducted in presence of a quantity of water insufficient to dissolve the cellulose derivative even at ordinary temperatures, and more water may be added while the mixture is still' hot. The dispersion treatment may be continued during the cooling with the progressive addition of further amounts of water. The cellulose derivative may be a methyl, ethyl, or methyl-ethyl cellulose ether. The effectmaterial may be a pigment, pigment lake, filler, e.g., talc, china clay, barytes, graphite, carbon black, zinc oxide, or metal flake powder, or a natural or synthetic resin or wax, e.g., carnauba wax, chlorinated naphthalene or diphenyl derivatives, or urea-formaldehyde resin, paraffin wax, or cetyl alcohol, or a fibrous filler, e.g., cotton fibre, or fibrous ethyl or benzyl cellulose. The compositions may be used in the production of crayons, pencils, furniture and floor polishes, or as printing or resist compositions for textiles, or compositions for filling, weighting, colouring, or modifying the handle of textiles.

Abstract: 329,872. Nimmo, J. June 17,1929. Wire-cloths; guiding and stretching mechanism.-In means for automatically maintaining belts and the like, for example, the wire cloth at the wet-end of a paper-making machine, on the centres of their pulleys or rolls, one end of the roll 1 is supported by a saddle 4 pivotally carried on a bogey 6 which moves to right or left under the control of blades 19 arranged on either side of the belt 2. The blades are linked to a pawl 13 which is supported by a link 18 and constantly raised and lowered by a crank, eccentric, &c. connection 16, 17 to the rotating roll, the pawl being moved into engagement with one of two ratchet wheels 11, 11a according to the direction of lateral wander of the belt 2.
