Abstract: 179,754. Kling, F. E., and Weidlein, L. B. March 21, 1921. Filtering.-A gas-cleaner comprises a battery of separate units each having a chamber divided by a vibrating screen with an inlet below and an outlet above the screen, the screens being shaken by means common to the whole battery while the outlet valves are simultaneously closed. Fig. 3 shows a filtering-chamber of a battery, in which a sub-chamber is formed by partitions 9, 10 and contains a filter mat 12 which may be formed of metallic wool held between sheets of wire gauze and provided with stiffening means; above the sub-chamber a pair of filter mats 16, 17 are disposed.

Title: Improvements in apparatus for the irradiation of biological specimens
IPC: G21K5/02
Filed: 1963-03-05
Abstract: 1,086,721. Irradiation apparatus. G. DIVITA and J. L. HAYBITTLE. June 5, 1964 [March 6, 1963], No. 8776/63. Heading H5R. Apparatus for the irradiation of biological specimens, e.g. small animals, living tissues, plants &c., comprises a cylindrical chamber, a radio-active source movable into the centre of the chamber and means for individually rotating the specimens within the chamber. The chamber 13, Fig. 1, is formed at the bottom of a pit in the concrete floor, the walls of the pit being lined by an annular lead shield 11 and the space in the pit above the chamber 13 being occupied by a cylindrical lead block 12. A circular frame 24, which can be lowered into the space between the block 12 and the outer shield 11, is connected by four rods 21 to a lead ring 20, which plugs the top opening of this space, and around which are attached cylindrical wire specimen cages (Fig. 4, not shown). The irradiation chamber is made gas-tight by two circular rubber washers 22, 23, one either side of the flange of ring 20. The ring is suspended from an overhead frame 35, by a number of springs, which allows it to be moved up and down by hand. The radio-active gamma source 41, of, for example, Co 60, is sealed in a stainless steel capsule screwed to the lower end of a stainless steel rod 42 which fits in the central bore of the block 12 and is also suspended from the frame 35. The source can be raised from its protected position below the pit, after release of an automatic locking device which prevents its movement when the lead ring 20 is not completely down, to a position at the centre of the chamber 13. The specimen cages are individually rotated about their own axes by an electric motor and gearing system above floor level, in order to obtain even irradiation of each specimen. Atmosphere control inside the chamber is by means of spiral input and output tubes 60, 61. Phantom specimens containing micro-detectors are used to obtain measurements of the exact doses given to living specimens.

Abstract: 565,900. Root crop harvesters. HALL TELEPHONE ACCESSORIES (1928), Ltd., and WILTON, H. J. HALL-. June 10, 1943, No. 9349. [Class 6 (iii)] [Also in Group XXX] A root crop harvesting machine is provided with a laterally projecting elevator which, when not in operation, can be folded to lie on the main frame of the machine. The elevator shown comprises a casing A housing a chain conveyer B which delivers potatoes to a trunk C for discharge into a cart. The conveyer chains pass over sprocket wheels D driven by a shaft E, the lower end of which is connected by a shaft G to a driving shaft H on the main frame J of the machine. The shaft E is made in two parts connected by a coupling F and the casing A is formed of two sections joined to each other by a hinge N against the coupling. Thus, by disengaging the coupling the upper section of the elevator may be folded over to lie on the frame J. The shaft H also drives a conveyer (not shown), which feeds the potatoes to a conveyer K which discharges on to a grid L, the latter having spaced bars so that fingers M on conveyer B can pass between them to carry the potatoes to the top of the elevator.

Abstract: 558,530. Mercury switches. SCHELLENTRAGER, E. W. July 6, 1942, No. 9351. Convention date, July 3, 1941. [Class 38 (v)] [Also in Group XVIII] An adjustable electric switch mechanism incorporated in the indicating dial of a weighing scale and which may be used for cutting off the flow of material passing into a scale car hopper employed for charging blast furnaces comprises a rotatable arm supported on the dial cover of the scale coaxially with the dialpointer, a setting device for the arm situated outside the dial cover and a switch part on the arm operated by the pointer. As shown, the rotatable arm 12 is mounted on the glass dial cover 16 co-axially with the indicating pointer 10 and may be rotated for setting purposes by a knob 20. Freely pivoted on the spindle of the arm is a frame 25 carrying a mercury switch 24 capable of tilting from the horizontal position to the inclined position shown. A counterweight 31 holds the frame in an upright position irrespective of the rotary adjustment of the arm 12. The mercury switch 24 is tipped to break or make the feed-operating circuit by the axial movements of a disc 30 connected by shafts 44, 41 to a V-crank 40, 40a. Fig. 4, which is thrown over by a pin 10a on the pointer. The mercury switch is in unstable equilibrium except at its extreme positions so as to free the pointer from load after being tripped. The switch device may be set to any point of the dial by means of the knob 20 and, by swinging open or removing the supporting cover, may be conveniently exposed for repair. The position of the arm is read on the dial by means of a pivoted extension 45. By advancing the position of the extension relative to the arm allowance may be made for the material dribbling into the scale hopper at the moment the switch is operated.
