Patent GB-894799-A (GB)
Title: Graph plotting mechanisms
Inventor: BEAKLEY WALTER ROBERT
IPC: G06K15/22
Filed: 1960-01-21
Abstract: 894,799. Electric selective signalling systems. AVIATION, MINISTER OF. Oct. 4, 1960 [Jan. 21, 1960], No. 2231/60. Class 40 (1). [Also in Group XIX] A graph plotting mechanism includes a rotatable cylindrical drum 5, a printing head 17, means 1, 11 for moving the printing-head parallel to the axis of the drum, a first pulse generating means 12, for generating a count pulse each predetermined incremental rotation of the drum, a second pulse-generating means 23 for generating a datum pulse each time the drum is at a datum rotational position and means 22 for changing the operational state of the printing head when the number of count pulses  occurring after a datum pulse equals a value to be plotted. As described, the ordinate of a point to be plotted is entered into a register 26 from where it is transferred to a subtractor, for example as described in Specification 884,533, which is referred to, to which are applied count pulses via a gate 21 which is opened at the beginning of a drum revolution by a datum pulse. When the subtractor reaches zero it emits a pulse which closes gate 21 and causes the printing head 17 to mark the graph paper, which is preferably electro-sensitive paper. The zero pulse output from the subtractor also causes, via a short delay 27, the ordinate of the next point to be plotted to be transferred to the subtractor. The successive points to be plotted may come from a computer under the control of a master pulse generator 2 forming part of the computer. As shown in the drawing the head 17 is moved uniformly parallel to the axis of the drum by a shaft 11. It may, however, be positioned manually or under the control of a servo system controlled by a further variable. A counter 14 coupled to the shaft 11 causes the printing head 17 to print a time scale on the graph. The count pulses may be produced, as shown, by photo-electrically sensing uniformly-spaced lines on the graph paper, or by magnetically sensing spots on the drum. In a modification (complete drawing not shown) the shaft 11 is driven step-by-step by a Geneva mechanism. Specification 717,114 also is referred to.

Filed: 1973-01-17
Abstract: 1408084 Vehicle crash restraint cushions SOC NATIONALE DES POUDRES ET EXPLOSIFS 17 Jan 1973 [19 Jan 1972] 2449/73 Heading B7B A vehicle safety cushion is provided with means for allowing atmospheric air to flow into or from the cushion interior, in-flow occurring at a first rate through inlet openings normally closed by flap valves and out-flow occurring at a second lower rate, through permanently open orifices, this arrangement allowing reinflation of the cushion following an initial impact. In a first example, Fig. 5, the cushion is formed with inner and outer chambers 8 and 7 of which the outer chamber is inflated from a pressurized gas source and the inner chamber is erected and filled with atmospheric air via orifices 10 during inflation of the outer chamber. The orifices 10 are controlled by inlet flap valve members 11 in which permanently open orifices 12 of small cross-section are defined. When a person is thrown against the inflated cushion air is forced out through the orifices 12 until the person stops pressing on the cushion, the outer outer chamber then re-erects the inner chamber and air is drawn in again through orifices 10. In another double chamber cushion, (Fig. 3, not shown) the inner and outer cushion walls 5, 4 are sealed together at various points so that the outer chamber is formed by a series of inter connected pockets. In this case the orifices 10 and flaps 11 are provided singly or in groups at the sealed areas. In a single chamber cushion arrangement, Fig. 6, the cushion is inflated by the joint action of springs 21 and gases generated from a pyrotechnic device and is provided with the same orifice/flap member arrangement as the above cushions. The springs effect re-erection of the bag between first and second impacts of the vehicle passenger. In further embodiments helical springs (Figs. 12 and 13, not shown) and leaf springs (Fig. 9, not shown) fitted respectively internally and externally of the cushion are provided to cause re-erection of the cushion.

Abstract: 650,029. Removing foreign bodies from webs of textile fibres. CLARK, D. M. (Forte, Dupee, Sawyer Co.). Jan. 27, 1947, No. 2472. [Classes 120(i) and 120(iii)] [Also in Group VIII] A fibrous web produced on a carding or similar machine is reduced to substantially single fibre thickness, with the fibres extending in a direction predominantly parallel to the direction of movement of the web, by damping the fibres and causing them to cling to a supporting surface advancing at a greater surface speed than that of the web; the web is then subjected to pressure to disintegrate foreign bodies present therein. A web F may be stripped by a comb C from a doffer 2 of a carding machine and carried by a belt 3 to rolls 16, 7. Roll 16 may be rubber covered and rotates more slowly than steel roll 7, so that moistened fibres in the web tend to be drawn parallel with the direction of movement. when their forward ends contact the roll 7. Moisture may be applied to the fibres by nozzles at S1 or S2, or by running roll 7 partially immersed in a water reservoir 12. Foreign bodies in the web are crushed between rolls 7, 8, the latter either being smooth, or having circumferential disintegrating elements, preferably formed by turns of steel wire. From the disintegrating rolls, the web F is carried by a rotary brush 17 to drying cylinders 30, 31, over which banks of lights 30a, 31a are provided. A series of rotary brushes, card clothed cylinders, or alternately located brushes and card cylinders 33, 34, 35, 36, 37 then pass the web of fibres to another main carding cylinder 38, most of the fragments of foreign matter being removed during their passage.

Title: Improvements in tungsten carbide purification
IPC: C01B32/949
Filed: 1958-01-27
Abstract: The content of trace metal impurities such as Fe and Mn, in tungsten carbide is reduced by heating a mixture of tungsten carbide and an alkali metal pyrosulphate to a temperature at which the pyrosulphate salt is molten, mixing the fused mass with water and treating the mixture with a base or thereafter washing the separated tungsten carbide with a dilute acid and then with water. Tungsten carbide is mixed with an alkali metal pyrosulphate, particularly potassium pyrosulphate, in proportion 1 : 1 to 1 : 20 or with at least sufficient pyrosulphate to react with all the trace metal present, and the mixture fused at 300-500 DEG  C., say 350 DEG  C., for 5-120 minutes, preferably 10-20 minutes.  The fused mass after cooling is mixed with water and the mixture treated with ammonium hydroxide and the tungsten carbide subsequently being separated by filtration and washed with dilute hydrochloric acid and finally with water to give a purified product. Alternatively, tungsten carbide may be mixed with potassium hydrogen sulphate or potassium sulphate moistened with sulphuric acid which then forms potassium pyrosulphate in situ on heating, subsequent treatment of the melt being as described above.

Drawings to Specification. [Classes 97 (i) and 98 (ii)] In the projection or projection-copying of lenticular colour or stereoscopic films, the angle subtended from the optical centre of each lenticular element, by the entrance pupil of the projection objective, is approximately equal to the sum of the angle subtended from the optical centre by the image of the exit pupil used in recording, which image is produced by the film in the focal plane of its lenticular elements, and of the angle subtended from the optical centre by the radiating surface of the light source. The angle subtended by the light source should be as small as possible, and the first-mentioned angle then approximates to the second. In the projection or projectioncopying of lenticular colour films of which the lenticular surface faces the projection objective, the angle subtended by the light source not being zero, the colour filter carried in the projection objective diaphragm has, in addition to the normal three bands, supplementary bands on either side of the normal bands, each of the same size as a band of the normal filter, and the bands being disposed in the same order as in the usual filter. In the projection of lenticular stereoscopic films on transparent screens comprising cylindrical optical elements, a light source is used, the radiating surface of which subtends a minimum angle in all directions at the optical centre of the lenticular elements, a narrow diaphragm is placed in the projection objective transversely of the lenticulations of the film, and the lenticulations are inclined to those of the screen.
