Abstract: 1,186,057. Dental vibrator device. B. A. O. EKMAN. 24 Oct., 1967 [26 Oct., 1966; 12 May, 1967], No. 48217/67. Heading A5R. A vibrator device for dental work, e.g. for application to amalgam fillings, comprises a first member 1 having a portion in the form of a sleeve and a second member 5 adapted to be fitted into the sleeve portion, the first member being adapted for being connected to driving means (e.g. a dental handpiece) by which the first member may be rotated about its longitudinal axis, there being means 7 suitable for preventing relative rotational movement between the first and second members, and there being means on the first and second members for imparting a vibratory movement to the second member when the first member is rotated. As shown, the device comprises a first member 1 to be rotated by a dental handpiece, the second member 5 fitting into a tapering socket 3 in the first member and having an arm 7 which bears against the handpiece (Figure 2, not shown) so that the second member 5 does not rotate. Cam surfaces 8, 9 ensure that, when pressed onto an amalgam filling with the member 1 rotating, the member 5 vibrates longitudinally. In an alternative embodiment (Figure 3, not shown) the second member (15), when the first memher (11) rotates, is given an oscillatory motion transverse to the axis of the device by an offset peg (14) on the second member engaging with a non-circular or offset bore (Figures 4, 5, not shown) in the rotating first member (11). The first and second members may be magnetically held together and it is stated that in a third embodiment the second member may be given the longitudinal vibratory motion of the device of Figure 1 combined with the transverse oscillatory motion of the device of the second embodiment.

An adsorption device comprises within a common outer casing adsorption units and heat exchanger units in series, separated by partitions which only serve to retain adsorbent in place, but which do not substantially alter the total internal cross-section over which the gas flows, which cross-section extends over the entire interface between the units. Successive adsorption units may be of different kinds and may be arranged' in groups each containing two or more units in series, such groups being separated by heat exchanger units, or alternatively adsorber and heat exchanger units may alternate in sequence. In Fig. 2, an adsorber (shown with the shell removed) has adsorption units 1 and cooling sections 2 comprising tubes 5 for the coolant. Gas passes up from 8 to 9. In Fig. 3 (not shown), the cooling section is restricted in cross-section by an obstacle 6 in the middle which may suitably be rounded or streamlined, so that gas flow through the cooling section is accelerated and becomes turbulent.

Abstract: 973,063. Weighing apparatus. E. L. CLEMENTS. Dec. 31, 1962, No. 49163/62. Heading G1W. [Also in Division B1] A mixing system has in combination, means 29 for delivering a predetermined weight of one component e.g. a mineral filler or aggregates such as stone or lime dust or cement, a mixer 31 comprising an open-topped container 33 and a rotary mixing element 32 disposed lengthwise of the container to provide a mixing space 35, Fig. 7, along the container between the side wall and the peripheral radial extent 32a, of the mixing element, and means 34 for accumulating a predetermined weight of a second component e.g. asphalt, water, or cement, the means 34 being disposed to dump the material contained therein through the top of the container 33 along the length of the mixing space 35, the material being dumped in a direction common to that of movement of the element 32 adjacent the mixing space. Fig. 1 shows an asphalt plant in which aggregates from a hopper 10 are conveyed to a drier 12, which is of the rotary cylindrical type with interior lighting flights, and is fixed by an oil burner 13, the aggregate then being fed to a vibratory screen 18 to grade the aggregates into compartments 19, 21, 22, 23 in a bin 24. Mineral filler is fed to a bin 27, the filler and aggregates being fed to the means 29, which is in the form of a weighing hopper adapted to register an exact predetermined weight of each size of aggregate from the bin 24 together with filler from the bin 27. When these weights have been attained the feed is stopped and the weighed mass is discharged to the mixer 31 via a hood 53, Fig. 2, covering the means 34, the hood serving to distribute the aggregates and filler to the mixing spaces 35. Simultaneously hot asphalt from a tank 42 is fed to the means 34 which takes the form of one or more trough-like members mounted for rotation on shafts 37. The asphalt is fed through branches 45 of a supply conduit 44 and the trough-like members are supported by a framework 38 attached by lever arms 39 to a weighing apparatus. When the predetermined weight of asphalt has been attained, the weighing apparatus serves to stop the feed of asphalt and to operate an air ram 50 to move a toothed rack 51 against the action of a spring 52 to rotate pinions 41 on the shaft 37 so that the asphalt is dumped into the mixer 31 along the length of the mixing spaces 35 as shown in Fig. 7. The mixer element or elements 32 has paddles mounted for rotation therewith for speedy mixing. The trough-like members may have integral deflectors 79, Fig. 2, at their ends to direct some of the asphalt from the ends of the mixer. The branches 45 may have flap valves as shown in Fig. 5 to prevent dripping of the asphalt, and these valves and the supply of asphalt may be controlled so as no delivery takes place unless the trough-like members are suitably positioned. Different arrangements of single and double trough-like members and mixing elements are described in the Specification.
