Title: Improvements in or relating to the treatment of gaseous mixtures for the purpose of separating them into their components or enriching them with respect to one or more of their components
IPC: B01D53/04
Filed: 1930-10-15
Abstract: Gaseous mixtures are separated by adsorption in a substance such as active carbon or silica gel, followed by fractional desorption at successively decreased pressures.  The fractions may be subjected to a repetition of the treatment.  The process is particularly suitable for the partial or complete separation of mixtures of permanent gases.  An example describes the separation of water gas into fractions suitable for (1) ammonia synthesis, (2) methanol synthesis, and (3) the conversion of aliphatic alcohols into acids.

Abstract: 1,220,624. Making valves. ACF INDUSTRIES Inc. 28 June, 1968 [25 Aug., 1967], No. 30905/68. Heading B3A. [Also in Division F2] A ball valve has the rotatable ball 34 made up of two hemispherical shells 84, 85 welded to each other and to segments 78 along edges 86, 80, the segments having been previously secured with integral or separate trunnion bosses 74, 76 to a tube 70.

Title: Sighting telescope for firing at a moving target
IPC: F41G1/393
Filed: 1956-10-11
Abstract: 805,908. Telescopic gunsights. FRANCAIS ETAT. Oct. 11, 1956 [Oct. 24, 1955], No. 30956/56. Class 92 Relates to a telescopic gun sight by which the angular speed of displacement of a moving target can be determined and, suitably combined with a time of flight corresponding to a predetermined range, applied to the sight line in the form of angular lay-off. The sighting telescope has vertical and horizontal graticules 4 and 5 visible in its focal field 1 which may be displaced respectively laterally and vertically by turning control knobs 6 (Fig. 5, not shown) and 7 proportionally to the required lay-off, a and to the inverse of the time of flight, T, of the projectile respectively. A grid of vertical lines 3 is arranged optically to move across the field 1 at a speed controlled by the knob 6 such that, when the speed of the grid matches the target's movement across the field, the knob 6 will have set the required lay-off deflection on the graticule 4. Fig. 2 shows diagrammatically a form of the gun sight as illustrated in Figs. 1 and 3. A direct current motor 10 drives a drum 11 at constant speed. The motion of the drum 11 is transferred to a disc 13 by a ball assembly 12 whose position relative to the disc centre varies as 1/T, where a = #T is the required lay-off for a target moving at an annular speed # measured from the gun at a distance equivalent to a time of flight T. The knob 7 transmits its motions through pinions and linkages 20-23 to a lead screw 25 (Fig. 3, not shown), which carries the ball assembly 12; simultaneously, through a pinion 26 and a shaft 27, it displaces vertically in the focal plane of the telescope a glass plate 33 carrying the horizontal graticule 5 to apply to the line of sight the extra elevation due to range. Another ball assembly 14 transfers the motion of the disc 13 to a drum 15. The movement of the ball assembly 14 is effected through other pinions and linkages by turning the knob 6 and is proportional to a. Simultaneously, the same movement displaces in the focal plane of the telescope a glass plate 29 carrying the vertical graticule 4 by the amount of deflection required for lay-off. The speed of rotation of the drum 15 is thus proportional to # = a/T and it can be made to rotate at an engraved drum as at 16 in Fig. 2 or to displace a grating 35 (as in Fig. 3, not shown), either of which can be illuminated and projected optically on to the focal field of the telescope in the form of moving lines 3. In another embodiment the quantities a and 1/T are multiplied electrically by applying them to potentiometers which control the voltages in two inductor windings of a direct current electric motor. (Fig. 7, not shown).

Title: Improvements relating to the detection of faulty vacuumised containers

Abstract: 1,006,543. Measuring the vacuum in a container electrically. BRITISH-AMERICAN TOBACCO CO. Ltd. Aug. 20,1962 [Aug. 31, 1961], No. 31418/61. Heading G1N. The concavity of an end 2 (Fig. 1) of a cylindrical container 3 depends upon the degree of its internal vacuum and controls the amplitude of voltage developed across a tuned circuit energized by a R. F. oscillator 6 and located near the end 2. The tuned circuit, comprising a coil 4 and capacitor 5, is located in a measuring head 7 which fits within the rim 1 and produces a voltage from a tapping 8 on the coil 4 which is rectified. When the vacuum is sufficient and the position of the container end is that shown at 2, the voltage prevents a trigger circuit 9 (Fig. 2) from operating: if the container vacuum is insufficient, resulting in deflection 2a and a voltage below a preset value, the trigger circuit 9 operates to de-energize a pilot relay 11 through an adjustable time delay circuit 10 thus causing a lamp 12 to be extinguish ed and a container rejection mechanism 14 to operate through a further relay 13. The output from the tapping 8 corresponding to the desired degree of concavity is adjusted by moving the coil 4 oxially within the housing 7, and making use of "go", and "no go" gauges. The time delay circuit 10 is adjusted so that the container rejection mechanism 14 operates for a sufficient time from a measuring voltage which may be of a relatively short duration. The head 7 may be incorporated into an automatic system for inspecting containers carried by a conveyer belt.

The buffer 9 abruptly decelerates the trough 1 causing a conveying movement of the material in the direction of the arrows along the trough 1 to a discharge aperture. The cylinder 3 may be suspended as a pendulum itself so as not to apply force to the frame 5.
