Title: Improvements in or relating to sheet metal articles and the formation of joints therein
IPC: B65D6/00
Filed: 1932-10-14
Abstract: <PICT:0408938/IV/1> <PICT:0408938/IV/2> In articles such as dye vats, having sides and a bottom made wholly of stainless steel or other metal in sheet form in combination with wood as a reinforcement, the meeting pieces of the sheet-metal sides extend together as at 1, 2, Fig. 1, from the inside to the outside of the article between the adjacent opposed portions of the reinforcement so that the joints are securely made without the necessity of working the sheet metal as by soldering, welding or brazing, when the composite sections of the article are bound together at the joints as by a tie-bar 7.  Further, in one form, at each of the joints between the sides of the article, the metal overlaps only those portions of the reinforcement which are adjacent the joint so as to clamp the metal and reinforcement together, as at 1<a>, 2<b>, Fig. 1; and in another form, Fig. 3, the sheet-metal portions after extending together at 1<f>, 2<d>, are bent back at 1<g>, 2<e> and are enclosed by a strip 13<a> of which the marginal edges are located under the edges of the sheet metal.  In the latter form, the joint may be used between mitred or rabbetted coacting members, and either form of joint may also be applied to the joints between the bottom and side-members.  The joints may be sealed by the use of solder or a filling-medium such as rubber latex or strips of rubber moulded or stuck together at their meeting edges. Further, screws, nails, rivets &c. may be employed for securing the backing to the reinforcement.

Title: Improvements in or relating to terminal or relay equipment for carrier systems
IPC: H04B3/10
Filed: 1958-09-11
Abstract: 885,338. Automatic volume control. GENERAL ELECTRIC CO. Ltd., and CROSS, F. D. Sept. 10, 1959 [Sept. 11, 1958], No. 29150/58. Class 40 (4). In a carrier telephone relay or terminal equipment of the kind in which a pilot signal is extracted from the output of an amplifier and is fed back to control a regulator which adjusts the gain, the extracted pilot signal is applied to the input terminals 10, 11 of a comparison circuit (Fig. 2) which produces an output signal at terminals 12, 13 only when the instantaneous voltage of the pilot signal exceeds the Zener voltage of a Zener diode 14, the smoothed output signal being fed to the regulator. As shown, the Zener diode 14 and a rectifier element 15 are connected in series between the terminals 10 and 12 such that the direction of reverse conduction through the former and that of higher conductivity through the latter are each towards terminal 12. During negative half-cycles of the pilot signal, the rectifier 15 will be non-conductive and no signal will appear at 12, 13 ; whereas during positive half-cycles the Zener diode will not conduct until the pilot signal voltage exceeds the Zener voltage. The output signal is therefore normally zero but its waveform will include the positive peaks of the pilot signal where they exceed the Zener voltage. In the case of direct working (i.e. increase in pilot level produces an increase in control voltage) this signal is smoothed and supplied to the regulator; but in the case of inverse working it is smoothed and backed-off by a fixed bias voltage, the resultant signal being supplied to the regulator. Smoothing circuits for both types of working are described with reference to Figs. 3 and 4, respectively (not shown). Reference has been directed by the Comptroller to Specification 752,412.
