Abstract: 769,627. Granulating urea-formaldehyde fertilizer. DU PONT DE NEMOURS & CO., E.1. April 7, 1955 [June 28, 1954], No. 10309/55. Class III. [Also in Group V] In the granulation of urea-formaldehyde fertilizer by a process involving the recycling of dried fine particles (including those of product size) and moist coarse particles to the granulation process, the proportion of dried fines recycled is directly controlled by the ratio of moist fines and moist coarse particles produced. As shown in the Figure, granular urea-formaldehyde fertilizer is formed by feeding a moist mass, e.g. filter cake from a filter 2, to granulating mills 1, 3, screening the granules product at 4, passing the moist fines to a drier 6 by a weigh belt 5, returning the moist coarse particles to the mill 1 by a weigh belt 14, after crushing at 13, screening the dried granules at 8, 9, returning the coarse granules and fines to the mill 1, and removing the granules of desired size. The rate of feeding of the dry particles to the mill 1 is controlled by adjusting the speed of the screw 11 in accordance with the weights passing over the weigh belts 5, 14. The filter cake may have a urea-formaldehyde mol ratio of 1.4: 1 to 1À6 : 1.

Abstract: 454,589. Television. BAIRD, J. L., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. April 4, 1935, No. 10515. [Classes 39 (i) and 40 (iii)] A beam of light passes through a matrix of electro-optical birefringent light-valves 6 which is scanned by an electronic beam 10. The electronic beam is deflected by plates 9 in the evacuated envelope 7, and the light from the source 11 is projected through a polarizer outside the envelope. At the transmitter the scene is focused on the matrix, or is illuminated through the matrix, and only that cell, on which the electronic beam impinges, passes light. At the receiver the electronic beam is modulated by the received signals, and each cell has a discharging time-constant which is rather greater than the time of a complete scanning. The matrix consists of a sheet of isotropic medium coated on one side with a translucent conducting film and on the other side with small discrete metallic particles. Alternatively, electrodes in the form of a grid are fixed between two transparent plates and the space is filled with nitro-benzene.

IPC: F16D67/00
Abstract: 105,900. Radcliffe, C. R. April 19, 1916, [Convention date]. Clutches and speed-varying mechanism. - In epicyclic variable-speed gearing of the kind in which two of the members are connected by an hydraulic clutch or brake, the clutch is of the centrifugal-pump type, its two constituent parts being connected to the driving-shaft and the sunwheel, respectively. The driving-shaft 14 carries a casing 10 normally connected by a cone clutch 19, 21 with a gear housing 18 carrying planetpinions 25 gearing with an annulus 26 on the driven shaft 17 and with a sun-wheel 27 on a shaft 28, respectively. The casing 10 and shaft 28 carry the parts 31, 32 of an hydraulic clutch or brake of the centrifugal-pump type, in which fluid circulates between radial vanes 33 and passes by centrifugal action outwards in the port 32, which normally tends to rotate the more quickly, and inwards in the port 31, thus completing the circuit, the effect being gradually to bring the parts 31, 32 to the same speed. When the shaft 14 is started, the shaft 17 momentarily remains stationary and the sun-wheel 27 and clutch part 32 are rotated rapidly. As the hydraulic action brakes the sun-wheel, the driven shaft is gradually started. By means of a lever engaging a collar 37, the shaft 17 may be moved to press the shaft 28 axially and engage a cone clutch 34, 35 on the part 32 and casing 10 for high-speed solid drive. If the clutch 19, 21 is now disengaged against the action of a spring 22 and a brake 39 is applied to the housing 18, a slow reverse speed is obtained.

A photographic roll film camera in which the film is advanced by operation of a lever 1 moving wheel 3 engaging pinion 7 associated with a sprocket to move the film is characterized in that the wheel 3 is movable axially relative to the lever 1 and is connected to this lever by a ratchet arrangement consisting of pressed out lugs 1a, 1b in the lever engaging apertures left by pressed out lugs 3a, 3b in the wheel. Towards the end of the lever movement one of the lugs 3a, 3b engages a bar 5 which is thus moved to allow the shutter release 8 to be operated. A cam surface 8a pivots bar 5, upon movement of the release 8 to disengage the bar from the lugs 3a, 3b so that it can slide under the action of spring 9 to lock the release 8. The bar 5 and a ratchet lever 6 resiliently support the wheel against the lever.

Where the polymerizable material contains residual epoxy groups, a cross-linking agent for these may be included, e.g. dicyandiamide (see Example 10). A free radical inhibitor is preferably also included, e.g. hydroquinone. In use the compositions are deposited from solution on to a substrate, e.g. a copper-clad laminate or aluminium, dried, and exposed to actinic radiation, e.g. from a mercury vapour lamp, imagewise if desired.

In a tubulous vapour generator comprising an upright pressure vessel having a cylindrical wall 1, heating fluid, for example the coolant from a liquid-cooled nuclear reactor, enters an inner chamber 10 of circular cross-section through an opening 7 and passes through annularly disposed apertures 13 in a tube plate 9 to a bank 17 of nested tubes of inverted U-shape, the axes of the tubes in each nest lying in upright radial planes, and then via a similar set of apertures 14 to an outer chamber 11 which lies around the inner chamber being separated from it by a wall 12.

Title: Improvements in direct current motor circuits

Abstract: 1,267,961. Control of D.C. motors. LANSING BAGNALL Ltd. 12 Feb., 1970 [28 Feb., 1969], No. 10898/69. Heading H2J. The shunt field winding 17 of a D.C. motor 14 is energized with pulses of current from a D.C. source 10 by a conventional arrangement of thyristor 20 and commutating circuit 21...24, the thyristors 20, 21 being alternately triggered from respective trigger circuits 28, 27 which are controlled by an astable multivibrator 26 whose output to the circuit 27 is fed through a network including a transductor 31 arranged to inhibit operation of the trigger circuit 27 when its core is saturated. The transductor carries a winding 13 responsive to the armature current of the motor, a winding 18 responsive to its field current and a winding 30 controlling the circuit 27, the flux in the transductor core being produced by an adjustable magnet 32 whose effect is augmented by the winding 13 and opposed by the winding 18. The motor drives a vehicle whose accelerator pedal 33 controls the magnet 32 so that the position of the latter determines the power developed by the motor. With the magnet 32 in a position producing maximum flux, the firing of thyristor 21 is inhibited until the field and magnet fluxes balance to produce a "standing field current" whose value is determined by the permanent magnet. Movement of the latter to reduce the transductor flux below the saturation level, produces a reduction of the field current until a predetermined weak value is reached corresponding to the magnet fully out and no inhibition of the circuit 27. Thereafter the field current is controlled by variation of the armature current, the arrangement being such that the field current increases with armature current after the latter has reached a predetermined value (determined by providing non- magnetic members in the transductor core). If the armature current is sufficiently high, inhibition of the circuit 27 occurs to produce a condition of maximum field current. During acceleration of the motor an appropriate proportion of trigger pulses from circuit 27 are inhibited until maximum speed is reached and the armature current falls to a level sufficient to allow normal triggering of thyristor 21 and return of the field current to the aforementioned weak value. When the vehicle encounters a gradient at full motor speed, the armature current increases to increase the inhibition of the circuit 27 and the value of field current as before. The "standing field current" condition determines the field current during rheostatic and regenerative braking. For the latter, the flux produced by the armature current is reversed to oppose that of the magnet and so reduce the field current as the regenerated armature current increases. For the former, no armature current flows and no flux is produced in the transductor core by the winding 13. The armature control circuit 15 may comprise conventional contactors and starting resistors.
