Abstract: 569,561. Locking cycles &c. against theft. MILWAIN, A. June 16, 1943, No. 7015. [Class 79 (iii)] Means for locking a cycle comprise a slidable radial bolt 15 movable by a key-actuated lock 22 through a hole in the steering-head frame tube 12 into a hole in the front fork stem 13 so as to lock the latter in a skew position, the lock having an eccentric pin 25 working in a slot in the bolt and holding the latter in either the locking or the inoperative position. The bolt and the look are carried in transverse bores formed in a casing which may be part of the cycle frame, or it may, as shown, be made in two parts 16, 17 secured together round the tube 12 by means of screws 18. The head of one of the screws 18 is normally covered by a plug 20 having a hole through which the bolt 15 passes, and the head of the other screw is covered by the lock barrel 22 which is secured by a dowel 24. Thus the screws 18 cannot be unscrewed until the lock is removed, after which the' bolt can be withdrawn and the plug 20 removed.

Title: Improvements in or relating to apparatus for carrying out chemical reactions
Inventor: MOULTON ROBERT JAMES
IPC: B01D11/02
Filed: 1962-02-23
Abstract: 971,188. Reactions between solids and liquids; dissolving. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 18, 1963 [Feb. 23, 1962], No. 7126/62. Headings B1F and B1Q. [Also in Division G6] Reactions between solid bodies and liquids, especially the dissolution of radio-active materials such as UO 2  and PuO 2  from cans containing said materials which have been cut into suitable lengths, are carried out in an apparatus comprising a reaction column to the upper part of which the solid bodies are fed, a collecting box connected to the lower end of the column of such a shape and so located with respect to the column that the solids passing down the column form a free surface therein, a discharge column leading from the collecting box at a position adjacent to and generally above said free surface, means for directing pulses to said free surface from a position below said surface and means urging solids disturbed from said surface by said pulses towards and along the discharge column. As shown in Fig. 1, the pulses are applied to a liquid in pipe 4 (covered by grating 5) whereby pieces of cans are caused to enter column 6 and progress up said column by reason of the step members 7 which (see Fig. 2, not shown) are of open construction to permit liquid pulses to pass therethrough. The dissolving liquid, e.g. nitric acid, used in column 1 may be admitted through line 11. Fig. 3 (not shown) illustrates the use of a second column which enters the collecting box at an angle of 45 degrees and a pulse tube lying along the projected axis of said column and entering the side wall of the collecting box below the upper surface of the mass of solids. In this case the column may have steps on the lower side thereof only or a flow of liquid may be admitted through the pulse tube which carries the solids through the second column. In a further embodiment shown in Fig. 4, the second column is shown at 6 and pulses are applied through tube 4. A stream of liquid admitted through additional tube 16 carries pieces of can thrown by the pulses out of the surface 3 into the column 6. The removal of pieces of can may be facilitated by introducing air bubbles into the stream as it enters tube 6.

Class 40(3) [Also in Group XXXVI] In an adjustable voltage dividing device, the input voltage V1, Fig. 1, is applied across a fixed resistance 5 and a light sensitive resistance 6 (see Group XXXVI) connected in series and the output voltage Vu is varied by varying the light incident on the light sensitive resistor. Various methods of varying the light are described, e.g. varying the light source intensity, Fig. 5 (not shown), applying the light via a rotatable disc of varying density or applying the light via a fixed aperture and a rotatable aperture, Figs. 3 and 4, (not shown), which may be formed in various shapes to provide a variety of potentiometer laws. In a further arrangement, Fig. 6, the input is applied to two light sensitive resistors 6, 60 connected in series and the incident light is arranged so that one resistor receives more illumination when the other receives less.

Abstract: 141,331. Soc. Anon. pour I'Exploitation d'Inventions I.S.A., (Assignees of Bogopolsky, J.). April 8, 1919, [Convention date]. Shutters.-A device for actuating a shutter comprises a clockwork-driven disk which is provided with means for producing a reciprocating movement which is transmitted to the shutter lever, the two phases of the movement being adjustable so as to vary the time of exposure. The clockwork-driven disk d has two adjustable arms b, b<1>. The arm b first rocks a lever c pivoted at g<2> and disengages a catch f from a plate i which is moved upwards by the spring r and operates the shutter push k. After a time interval determined by the separation of the arms b, b<1>, the arm b<1> rocks a second lever c<1>, g<1> and disengages a catch f<1> from the casing p containing the spring r, and the casing then descends under the action of the tensioned spring r<1> and that of the shutter push k, thereby closing the shutter. The levers c, c' are returned by a flat spring o. An alternative similar construction is also described, and in the Specification as open to inspection under Sect. 91 (3) (a) a further construction is described in which the shutter push k is actuated by a revolving cam shaped disk with an adjustable portion to control the time for a bulb exposure. This latter modification does not appear in the Specification as accepted.
