Abstract: 665,814. Musical drums. SOMERVILLE, J., (trading as RENO ELECTRICAL & ENGINEERING CO.). March 3, 1946. [March 3, 1945] No. 5361/45. Class 88 (ii). The head of a drum is tensioned by pulling it over a ring formed on an inner rigid openwork framework concentric with and fixed to the shell at points remote from the head. The ring is spaced from the flesh hoop as described in Specification 626,688. An apertured inner shell 3, Fig. 1, is provided with rolled over edges 3a to bear against the head 6 and can be moved axially of the outer shell against the tension of the heads. Each head is carried on a flesh hoop 7 which is adjusted to tension the head by pins 10 engaging in inclined slots 9 in the counter hoop 8. The pins are mounted on a ring 11 which can be turned round the inside of the.shell either by a worm 15 and rack 13 as shown for the top head or by a Bowden-cable mechanism 20 operated by a treadle as described in Specification 626,688 and is guided by rollers 12 or other guides. The two heads can be tuned to a selected low note by the worm and rack and can be temporarily adjusted for higher notes by the treadle. The shell is flanged to form a rim 2. In a modification, Fig. 2, the inner shell is replaced by a frame 21 fixed to the shell with intervening washers 22 and carrying pressure rings 21a. The two heads are tensioned independently by separate worm and rack mechanisms 25. The rim 23 consists in an angle member, provided with cam formations 23a to engage with similar formations on the shell. A tripod 29 having a central boss 30 is fitted to the drum shell so that the drum may be mounted on a stand with a universal connection. The rim mav alternatively be formed on the counterhoop, Fig. 3 (not shown). The shell may be formed in coaxial parts which are adjusted by means of pins 46, slots 45 (Fig. 4) or by a screw connection to a part 52 (Fig. 5). The shell may be elliptical (Fig. 6), or polygonal and may have tension-adjusting means 66 indicators 67 and snare control levers 68. Lidlike covers may be fitted over the ends of the drum. The hoops or rims may be covered by an internal frame forming part of a console outfit as described in Specification 650,021.

[Classes 52 (ii) and 52 (iii)] A stool is carried by a collapsable frame comprising at each side an X-frame 19 with pivot rod 21 connecting the two side frames, arms 26 pivoted to the X-frames and to a trunnion 14 at each side of a reversible top 10 one surface of which is padded as at 13 to present a stool surface and the other surface forms a table or a tray, further arms 28 are pivoted to the X-frames and serve as supports for the top 10 in its various positions. By swinging the support arms 28 inwardly and collapsing the X-frames the arms 28 may contact the floor to provide a low stool. In other positions the top may form a foot stool or back rest as shown in Fig. 5 or the top 10 may be supported entirely by the arms 28, the X- frames being totally collapsed, to form a bed tray or a low table. In other positions it may be supported on the arms of an armchair as an auxiliary table. The arms 28 are provided with lugs 30 engageable with the ground or with various members of the frame to prevent undesired collapsing.

Abstract: 812,604. Electric selective signalling systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 21, 1957 [Feb. 23, 1956], No. 5630/56. Class 40 (1). The angular position of a shaft Sh, Fig. 1, is sensed by a brush Br and fixed contacts S and represented digitally by four relays A, B, C, D, Fig. 3, the equipment being characterized in that the sequence of combinations of energizations of the four relays A, B, C, D as the shaft turns through its 15 positions, namely is formed from a basic sequence of combinations B and a logical sum sequence L each combination of which is the logical sum of two adjacent combinations in the basic sequence, the logical sum being computed digit-by-digit on an " or " basis, i.e. 0+0=0, 0+1= 1, 1+0=1 and 1+1=1. In the embodiment described the eight fixed contacts S, connected as shown, Fig. 3, via rectifiers to four relays, are so arranged that as the brush Br wipes them it contacts alternately one contact and then two adjacent contacts. A code having the above properties (that is that it is constituted by a basic sequence and a logical sum sequence) has the advantage, in the type of device described, that it requires fewer diodes than other codes. Other examples of codes of this type are described.

[Also in Group XVII] In apparatus for feeding curved-walled containers e.g. bottles in which the containers are moved between guides 2, 3 over a stationary plate by the pressure of succeeding containers, the stream of containers normally proceeds to e.g. a filling machine between guides 5 disposed at an angle to guides 2, 3 but a gate 4 can be opened to allow ejection of a contaminated container from the stream and, when the gate is opened, a stop 22 is moved into the stream to prevent advance of the preceding container. As shown, a worm 1 is adapted to feed the containers and to hold them stationary for a moment at inspection apparatus located at station B. If the container at B be contaminated a solenoid 6 is energized and raises a plunger 7 in a drum 8 rotated by worm 1 through stepdown gearing the ratio of which equals the number of plungers 7. When the contaminated container reaches gate 4, the raised plunger contacts cam 10 to move lever 11 clockwise about pivot 12. This movement pushes link 13 to turn arms 16, 17 anticlockwise about pivot 15. These arms carry gate 4 and stop 22 respectively and the gate is thus opened to allow discharge of the contaminated container and the stop is moved in front of the preceding container. A spring 21 restores arms 16, 17 to their normal positions. Arm 17 is yieldable against spring pressure relative to arm 16. A ramp 29 restores plunger 7 to its inactive position Specification 849,151 is referred to.

A method of making seamless metal bottles, particularly lacquered and or printed aerosol bottles, in which a cup-shaped hollow body preferably produced by impact extrusion is formed into a bottle by necking, comprises lacquering and/or printing the body, necking the open end by rectilinearly moving shaping tools, making the base convex, cutting the neck to length and beading the rim. Extruded metal bottle blanks 14, lacquered and/or printed, are placed in workholders 11 attached to a rotary carrier plate 10 driven and indexed by a motor 12 via worm gearing 13 and mounted on a press 22. Tools 16 are mounted on a top plate 15 attached to a ram, located by dowels and arranged coaxially with the plate 10. The workholder comprises a shaping element 23 and a closing device 24. The top plate 15 is lowered after each index so that the tools progressively form the blanks 14 into a finished bottle. A convex form is produced in the base of the blank with the device 24 in the unclamped position, the blank is then clamped and a series of drawing tools 16 comprising a mandrel 26 and a shaping element 25 used to neck the blank. Subsequently, a motor-driven tool 18 comprising a cutter 31 inserted in a piloted spindle 33 bearing in a guide 32 and having a packing 35 is inserted in to the open end of the bottle to face it to length. The packing 35 prevents swarf entering the bottle, upon removal of the tool the guide 32 gathers speed and centrifuges the swarf away, preferably it is removed by a suction device. The rim is finally beaded using a series of shaped tools 27 and the bottle removed from the unit in a known manner.
