Title: Tension apparatus for use in the draft system of textile machines
IPC: D01H5/26
Filed: 1965-07-15
Abstract: 1,098,799. Drafting-apparatus. S. KITA MURA. July 15, 1965, No. 30086/65. Heading DID. Means for tensioning the lower apron of drafting-apparatus comprises a tensor-bar urged against the apron by a reciprocable slide movable under spring-action over-an inclined member depending from the bar. A tensionbar 8 is common to a number of aprons and has a depending member 8' on which are mounted a number of sliding members 12, one for each apron. These members are guided while they slide by pins 16, 17 on the member 8', the former pins being disposed in slots 15 and the latter engaging the sides of the slide. The slides are arranged in pairs; between each pair and the tensor-bar is a spring 13 adjustable by a set-screw 32. The slides have skirts 11 bearing against the apron at the opposite reversal point to the tensor-bar, and guides 12, 12' for the apron. Above the slides and below a fixed cover plate 19, is a plate 22 movable to right or left by a handle 28 to an extent limited by a member in a slot 23. The plate 22 carries a spring 25 for each associated pair of slides, the spring having at each end pawls 26 downturned into apertures 14 in the slides divided by a lug 29 into front and rear portions 14', 14". When the apron is under tension, the parts are in the positions shown, with the plate 22 to the right and the pawls 26 in the openings at 14", the slides being thus free to be moved by the springs 13. When it is desired to change an apron, the plate 22 is moved to the left and the slide is pushed back against the springs 13 so that the corresponding pawl moves into the opening 14' and retains the slide by engaging the lug 29, thus releasing the tension in the apron. To .tension the apron, the plate 22 is moved to the right to release the slide by withdrawing the pawl. The skirts 11 are interchangeable to suit aprons of different widths.

A railway vehicle buffer comprises a spring 21 having a rising load/travel characteristic A, and a piston and, cylinder 12, 8 which upon buffer compression displaces liquid into a reservoir 17 through orifices such as 15 whose effective area falls during compression, wherein the rate at which the effective area falls during compression is so reduced that for a specified vehicle weight and maximum permissible velocity of impact, the resistance provided by the orifices has a falling load/travel characteristic B which added to the spring characteristic A provides a substantially uniform characteristic C. To achieve this the velocity of the plunger 3 should fall uniformly from the moment of impact, and the flow of liquid displaced by the piston from the cylinder should also fall uniformly. The orifices 15 should be either uniformly spaced and increase progressively in hole size towards the headstock 1, or should be of the same hole size but spaced progressively closer together as shown. A split ring 5 sliding in a bore 6 provides an inner bearing for the plunger 3 and an extension limit stop.

Title: Improvements in or relating to navigational guide systems

Filed: 1930-10-17
Abstract: 356,969. Electric signalling systems. HAMMOND, J. H., Hesperus Avenue, Gloucester, Massachusetts, U.S.A. Oct. 17, 1930, No. 3119. Convention date, Oct. 29, 1929. Addition to 356,906. [Classes 40 (i) and 118 (ii).] A visual indication of his actual position relative to the landing field is transmitted by wireless to an aviator as he approaches an aerodrome. His course through the air is followed by directional loop aerials on the ground, changes in the angle of orientation being used to control the frequency of a train of wireless signals transmitted from the ground whereby the angular changes are repeated on the aircraft and employed to give the required visual indication. The setting of each loop aerial 45, Fig. 2, controls through a shaft 125, Figs. 2 and 4, and bevel gearing 74, 75, the setting of variometers 126, and therefore the frequency of the oscillations generated by the valve 128. These are imposed as a note signal on a carrier-wave and transmitted to the approaching aircraft from the aerial 135. In the output of the aircraft receiver, Fig. 5, is a dynamometer indicator 152 which, when the beat note between the incoming signal and a local oscillator 146, has a predetermined frequency rests midway between the contacts 153, 154. As the frequency of the incoming signal changes (with the orientation of the ground loop) the beat note alters and the needle 152 moves against one or other of the stops 153, 154. This drives a motor 157 to rotate a shaft 140 until the variometers 147 adjust the oscillation period of the valve 146 to give the predetermined beat frequency. In this way the angular movement of the ground aerial is repeated by the shaft 140. The corresponding movement of the shaft of the motor 157 is transferred to repeaters 213 on the optical indicating device shown in Fig. 6. This indicator which is mounted behind the instrument board on the aeroplane, comprises a source of light 219 feeding rays through horizontal tubes 208 having downward extensions arranged over a map at positions corresponding to those of the direction-finding loops on the landing field. The repeaters 213 control the projection of the light rays 34, 35, 36, Fig. 8, so that the latter converge at a point 222 on the map which corresponds to the location at any given moment of the aeroplane relative to the landing field, particularly at night or in foggy weather. The ground direction-finding loop aerials may be replaced by equivalent sound-ranging devices.
