Void [Published under Sect. 91 of the Acts]. [Class 98 (i).] A grid for intercepting secondary radiation consists of at least two parts, the laminations of which are arranged with their longitudinal axes entirely or partly oblique to the direction of travel and which are located relatively to one another in such a manner that the projections on the plane of the picture of the one part cut those of the laminations of the other part whilst these two parts travel in substantially opposite directions. The grid may be constituted by the two parts of an endless travelling chain, having strip shaped laminations oblique to the direction of travel. To ensure that the laminations readily pass round the rollers they may consist of a plurality of juxtaposed elements 3, Fig. 2, which join to elements of the preceding and following lamination so that the projection has the shape of a large number of intersecting lines. Alternatively the laminations may form zig-zag or modulating lines and with contiguous tops, Fig. 4. The laminations take up only a slight distance in the direction of travel. For guiding the laminations, chains, bands or other flexible members may be used. Each lamination may be mounted in or on a material transparent to X-rays.

Patent GB-673433-A (GB)
Title: Improvements in and relating to the production of secondary cyclic amines
IPC: C07C209/18
Filed: 1950-04-06
Abstract: Secondary cyclic amines are prepared by treating a primary cyclic amine with an aliphatic carbinol in the presence of a catalyst comprising a mixture of metallic copper, alumina, and one or more difficulty reducible metal oxides.  The alumina is preferably activated alumina.  The other difficulty reducible metal oxide used acts as an activator and for this the metals of Group II are specially advantageous.  Examples of suitable oxides in decreasing order of preference are the oxides of calcium, zinc, chromium, magnesium, ferrous iron, cadmium, and potassium. Preferred amounts of copper in the catalyst comprises from 2-20 per cent.  The molar ratio of activating difficulty reducible oxide to copper is from 0.2 : 1 to 4 : 1.  The catalyst is prepared by impregnating alumina with a salt of copper and of the difficulty reducible metal oxide selected, and calcining at 250-400 DEG  C.  If desired the catalyst may be supported on a carrier.  The reaction of the amine with the alcohol takes place at 200-275 DEG  C., preferably as a continuous process. It is stated that by the use of the special catalysts according to the invention, and by the use of an excess of alcohol, the substantial total suppression of the formation of tertiary amines is possible. Amines mentioned which may be produced according to the invention include N-methylaniline, other N-alkylanilines, N-alkyltoluidines, N - alkylnaphthylamines, N - alkylcyclohexylamines, and secondary heterocyclic amines.  When unsaturated alcohols are used such as allyl and methallyl alcohols, the product is a saturated amine if the treatment is carried out in the presence of hydrogen.  Polyhydroxy alcohols, such as glycol and diethylene glycol may also be used.  Examples of varying reaction conditions and different catalysts are given.

The casing 3 is in two parts, 4, 5, the former providing an exhaust chamber 8 which has a vent 9 and the latter providing an outlet chamber 7 separated by a partition 6 from a space 51 below a diaphragm 24 which is clamped between the two parts. The 'valves 13, 14 are connected by a rod 15 and the inlet valve 14 is located in an inlet housing 10 which has a valve seat 12 against which the valve 14 is pressed by a spring 16. The valve is moved from its seat by a plunger 17 which contacts the exhaust valve after a limited downward movement. Passages 18, 19 in the plunger connect the chambers 7, 8. The plunger 17 has a shoulder 22 which engages the diaphragm 24 after a limited downward movement, the plunger having a close sliding fit in the diaphragm. The plunger is pressed upwardly by a spring 23 acting on a nut at its lower end and the diaphragm is similarly pressed upwardly by a spring 25 against a piston 28 with ports 32. A restricted passage 52 connects the chambers 7 and 51 so that pressure builds up less rapidly in the latter than in the actuator 49. The pedal 37 is mounted on the casing by ears 32, 34, and a pin 35. The plate 36 is similarly mounted on the pin 35. Four leaf springs 39, 40, 41, 42, are secured to the pedal 37 by a rivet 44. A bar 43 on the plate 36 passes through the pedal 37 and engages the spring 39 which at its free end engages a pin 31 slidable in the piston 28 so as to contact the upper end of the plunger 17. The free end of the spring 42 engages a stem 30 on the piston 28- On depressing the plate 36, the lost motion 53 between it and the pedal is taken up, the spring 39 is stressed and the exhaust valve is closed due to the depression of the plunger 17 the shoulder 22 on which now engages the diaphragm. On further depression of the plate 36, the plate and the pedal move together to open the inlet valve 14 and admit pressure fluid from the reservoir 46. The diaphragm 24 subsequently rises to close the valve 14 and open the valve 13 under any pressure in excess of that corresponding to a given setting of the pedal assembly. Preferably the spring 42 is stiffer than the spring 39.
