Abstract: 618,555. Antiseptic toothbrush containers. BOOSS, E. Oct. 28, 1946, No. 31874. Convention date, Nov. 1, 1945. [Class 81 (i)] [Also in Groups XVII and XXIII] A toothbrush container having a compartment containing a germicidal volatile substance is characterised in that the compartment has the form of a twopiece capsule push-fitted into one end of the container in such a manner that the outer end of the capsule is flush with the adjacent rim of the container barrel and removably maintained therein by friction. In the form shown in the drawing the container barrel 1 is closed at the bottom end by a detachable cap 2, and has its top end closed by a pressed in capsule the outer end of which is flush with the adjacent rim 1a of the barrel. The capsule consists of a top 3 with a flanged edge and a bottom 4 with a similar flanged edge and when closed the top and bottom are joined by the overlapping flanged edges. The germicidal substance is in the form of a pellet 5 which can vaporise into the barrel of the container through holes in the bottom part 4. The flanged edges of the top 3 and bottom 4 are each provided with radial slits 8 which divide the edges into separate segments. These segments spread slightly when the capsule is removed from the barrel so that in the closed position shown they press against the side of the barrel 1 effecting a frictional closure. The pellet 5 is removed by removing the cap 2 and pushing the capsule 3, 4 out of the barrel by means of the tooth brush contained therein.

Boxes; locking-followers.-In a filing-cabinet of the type provided with a fall-down front and with a transverse rod countersunk in the bottom of the cabinet parallel to the hinge axis of the front, and passing through files and guide cards held vertically at right-angles to the front, a followerblock having a base-piece with an extended bearing on the rod serves to hold the files and cards vertically. The rod may be countersunk in a false bottom of the cabinet, the front being so hinged that, when in its lowermost position, it forms an even surface with the true bottom to facilitate forward movement of the false bottom on to the lowered front. In the form shown in Fig. 1, the rod 7 is introduced into the slot 6 in the bottom of the cabinet through an aperture in one side, the end of the rod being screwed into a nut member 8 by means of a countersunk screwhead 9 on the rod. The guide cards 10 and follower-block 13 have perforated extensions entering the slot 6 and engaging the rod 7, that of the block 13 being sufficiently extended to give a good locking action between the block 13 and rod 7. The top of the cabinet may have a flange 20 to form a receptacle for loose papers, and the front may be guided by slotted quadrants 3 and fastened in its closed position by a spring-ball catch 16. Dust-excluding strips 15 lined with material such as felt may be provided on the sides and top of the cabinet. In a modification, the rod may be introduced into the slot 6 from the front of the cabinet, its ends being engaged bv fittings such as snap fastenings within the slot.

Fixed-chamber apparatus for semi-liquids, valve systems for; varying quantity measured in.-Means for dealing with molten tar comprises a measuring cistern 1 with inlet pipe 3, outlet pipe 11 and overflow pipe 6, the inlet and outlet pipes being controlled by valves 4, 10 interconnected by a rod 21 and operated by a chain-wheel 16. The inlet pipe leads from a pump which forces tar from a boiler and the inlet valve 4 has a passage leading to the overflow pipe 6 so that when the delivery valve is open the valve 4 is turned to put pipes 3 and 6 into communication, diverting the flow back to the boiler. Within the chamber is an inclinable delivery pipe 7 jointed at 8 to a pipe 9 connected to the delivery valve 10 ; the inclination of this pipe can be varied by turning a pointer 12 outside the cistern, and the pipe can be fixed in any position by a nut 14. The amount delivered is thus the value between the overflow pipe 6 and the delivery pipe 7. A valvecontrolled drain pipe 24 is connected between the base of the cistern and the overflow pipe 6.
