Abstract: 788,990. Electro-acoustic transducers. BENDIX AVIATION CORPORATION. Dec. 12, 1956 [Jan. 3, 1956], No. 37996/56. Addition to 774,043. Class 40 (4). In a motion transformer for producing compressional waves in liquids and comprising a plurality of legs of the type described in the parent Specification, lateral strut means is provided between the legs to modify the natural lateral vibration periods so that they cannot adversely affect the longitudinal vibrations. As shown, Fig. 1, the strut means consists of a web consisting of three portions 16a ... 16c. In the case where four legs are used, continuous webs may be used connecting the legs and diaphragm to form a continuous surface preventing the liquid from reaching the back of the diaphragm and causing corrosion. Thus the motion transformer, Figs. 8, 11, consists of a hollow member, the thickened parts 33 of the walls corresponding to the legs and the thin parts 34 to the webs. The member may be made in two parts 30a, 30b, which are brazed or cemented together at a conical interface. Radial stiffening ribs 37 may be provided for the diaphragm. In a modification, Figs. 9, 10 (not shown), the interface between the two portions is horizontal. In a further modification, Fig. 14, the interface 41 between the two portions is vertical, each portion consisting of a wedge-shaped part 42 having a cross-section as shown in Fig. 16.

The apparatus maintains its own supply of tubes from a magazine charged with rods formed by "telescoping" or nesting several tubes. As shown in Fig. 1 a mobile package/tube changing apparatus 30 is driven by electric motor 31 to shuttle along and serve the winding stations. The elevator magazine 54 comprises (ten) pivotallysupported, chaindriven, tube-rod supporting troughs 62 each successively raising a rod to a top position whereat, with apparatus 30 in end position shown, a trough is on the same level and in alignment with the supply trough 36 of a tube accepting and storage apparatus 35 (forming part of and moving with apparatus 30). Actuation of an end switch 74 connected to a programmed switch installation 76 starts a motor 72 which, through a chain drive 71, operates a transfer apparatus 64 wherein a plunger 68 attached to a carriage 65 enters a rod and shifts it for presentation to apparatus 35 wherein one or more empty tubes, as may be necessary to restore a complete rod (or set thereof) for subsequent servicing to winding stations, is/are detached, as by hooked members, from the supply rod and added to the service rod(s). The otherwise continuously moving apparatus 30 is normally only arrested for package changing and take-over of empty supply - tubes.

A housing for enclosing a semi-conductor element has a first housing part connected directly or indirectly by hard soldering or welding to a second housing part, and has a shield between the joint and the semiconductor element protecting the latter from material produced by the jointing process and acting as a guide to locate the second housing part relative to the first. Two embodiments are illustrated in which silicon rectifiers are enclosed in casings differing mainly in the formation of their shields. Fig. 1 shows an embodiment having a shield 8 integral with the base-plate. This is surrounded by a ring 9 of a metal such as iron which is hard soldered to the base-plate. When the other part of the housing is projection welded to this ring at the ridged portion 9a, sputtered material cannot reach ,the semi-conductor element. In the embodiment shown in Fig. 2 the shield is formed by an upturned part of the ring 15 which is hard soldered to the base-plate and to which the cap is subsequently welded. The rim of the ring 15 which contacts the inner surface of the cap may be slightly studded, Fig. 3 (not shown), or insulated over most of its area to prevent substantial current from by-passing the desired welding area along ridge 9a. The outer surface of the upper part of the shield 8 in the first embodiment may be similarly treated. It is stated that the shield may be one of a number of portions of the housing parts which interengage to form a labyrinth.
