Title: Improvements in or relating to linear-dimension gauging devices
IPC: B07C5/08
Filed: 1943-07-22
Abstract: 596,359. Weighing-apparatus. SHEFFIELD CORPORATION. July 22, 1943, No. 11949. Convention date, Aug. 28, 1942. [Class 143] [Also in Group XIX] Articles, such as cartridges, which have passed through a linear-dimension gauging machine (see Group XIX) are fed to a weighing apparatus which sorts them into two groups depending upon whether each is or is not below a standard weight. The cartridges are delivered to a hopper having at its base a feeding wheel 113 which feeds them one by one to trays 115 on arms 96 on a rotary table 95. The feeding wheel 113 is operated by cams on table 95 which rock a lever 124 to reciprocate a slide 126 carrying a pawl 127 which drives the feeding wheel as a tray 115 passes beneath the hopper. The lever 124 is in two parts connected by a spring which allows relative movement if a cartridge jams in the feeding wheel, this movement opening the circuit of a driving motor. The ends of the arms 96 engage a fixed cam 119 to keep the trays 115 lowered while receiving a cartridge. If the cartridge is not below the standard weight, the tray remains lowered when the end of the arm leaves the cam 119 and the cartridge is later deflected by a fixed stop into a hopper. If the cartridge is too light the arm 96 rocks clockwise to elevate the tray 115 so that the cartridge meets another stop and is directed into another hopper. Cartridges passing to the first hopper close contacts operating a counter.

Abstract: 1,151,326. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. 14 March, 1968 [28 April, 1967], No. 12567/68. Heading G6C. A fuel element comprising fissile material between blanket layers of fertile material is made by adding precalculated quantities of the different materials which are of the same relatively large diameter to a container in succession, the container being vibrated to compact the material into layers within the container. A pressure thimble containing a screen having openings smaller than the large diameter material is applied to the material to hold it in place and prevent comingling between layers. Successive amounts of smaller diameter materials are then added to the container in the same order as those already in the container and are also compacted by vibrating the container. The amount of each smaller diameter material which is added in precalculated to just occupy the space remaining in the existing layer of the same material. A simple electromechanical vibrator operating at 60 c/s. provides adequate axial vibration to compact the materials and transverse shock or vibration to prevent bridging is imparted to the container by a rattle cage placed over it which bounces back and forth against the container side because of the axial vibration. The density of the fuel element may be further increased by the addition in a similar manner of materials of a still smaller diameter.

Abstract: 528,388. Feeding articles to weighing and other apparatus. BEST, C., and MOLINS MACHINE CO., Ltd. April 27, 1939, No. 12618. [Class 143] In apparatus wherein a conveyer delivers articles in succession to a receptacle (for example, a scale pan) the conveyer has a pocket arranged to move through an arcuate path while delivering articles to the receptacle, the pocket being so arranged that the top of the leading wall of the pocket is at a greater distance from the centre of the arcuate path than the top of the rear wall and passes through a position to be occupied by an article on the receptacle. As shown in Fig. 1, a rotatable suction device 9 picks up cigarettes c successively from the catcher band 11 of a cigarette-making machine and carries them into the path of a pair of prongs 8 projecting from a rotary conveyer 3. The prongs 8 remove the cigarettes and in co-operation with fixed guides 15 deposit them successively into a scale pan 2 where they are retained during the weighing operation by a flexible prong 6 as described in Specification 425,700. The weighed cigarettes are positively removed from the scale pan by prong 7 and are guided back to the catcher band by a pivoted flap 17. In a modification, Fig. 3, for dealing with heavier articles, e.g., cardboard containers filled with tablets, the articles are transferred from a shoot 38 to a recess 32 in a rotating conveyer 31 by means of a rocking arm 34 and as the conveyer rotates, roll into a recess 33. A cam portion 35 of the rotating conveyer thrusts the previous article (resting on a V-shaped scale pan 24) off the scale pan, and the article in the recess 33 is deposited on the pan as the conveyer continues its rotation. A grooved guide 30 limits the movement of the pan. The scale beam 20 pivots about a stretched wire as described in Specification 527,983 and is provided with a pointer 22 co-operating with a graduated scale. The rotating conveyer 31 may be modified by replacing the cam 35 by cam-operated pawls which eject the articles from the scale pan by a lifting action. In a further modification, Fig. 6 (not shown), the articles' are removed from, and deposited on, the scale pan by two separate conveyers. Specification 425,721 also is referred to.
