Title: Improvements in or relating to protective headgear
IPC: A62B17/04
Filed: 1948-05-13
Abstract: 647,106. Respiratory appliances. CALDERBANK, A. May 13, 1948, Nos. 13105/48, 27196/48, 3231/49 and 4742/49. [Class 81(ii)] A protective headgear, of the type comprising a helmet enclosing the head and a cape connected thereto and fastened about the shoulders, has the outer part of the helmet made of rubber or similar material homogeneously formed with the cape and supported by a relatively rigid internal former inseparably associated, or in close contact, with the helmet so as to provide a substantially continuous support for the helmet from the crown to below the vision opening. The rigid former may be either a complete shell made, for instance, of ebonite or synthetic resin or it may be of metal, in which latter case it may support the hood or it may be embedded in it during manufacture. In one form a domed ebonite helmet 15 is covered by a rubber outer layer 14 which is continued downwards to form the cape 16 and is bonded to the ebonite. A window 28 of transparent material such as cellulose acetate is provided at the front of the helmet and air is admitted through a pipe 25 leading to a nozzle 29 which directs the air downwards over the window. In an alternative form the rigid support does not extend down to the shoulders but the weight is taken partly by an internal caplike fitting, which engages the crown of the head, and partly by the portion of the cape which is around the neck, this being suitably reinforced with stiffening material such as canvas, (Fig. 5 (not shown)). This latter type enables the hood to be moved with the head. The window may be formed by slipping a sheet of transparent material under a peripheral beading, by sliding it into a slot formed between the surface of the hood and an attached frame which is open at the top or by holding it in position by a rubber frame, reinforced with ebonite or metal, with one edge bonded to the material of the helmet.

Title: Improvements in or relating to amplifying systems for weak electric currents
IPC: H03F3/32
Filed: 1929-05-01
Abstract: 310,857. Bristol Talking Picture Corporation, W. H., (Assignees of Thompson, L.). May 1, 1928, [Convention date]. Thermionic amplifiers.-Valve amplifiers are arranged to work without a negative bias on the grid by connecting a unilateral conducting device, preferably in the form of a second valve, in shunt across the input circuit, said device being designed to pass a current during one half-cycle equal to the grid current of the amplifier during the other half-cycle. As shown in Fig. 1, a microphone 19 feeds a transformer 10, the secondary of which is connected across the grids of two amplifying valves 13, 20. The grid of each amplifier is connected to the filament of the other. The output may be taken from the plate circuit of either valve, or from them both jointly by a differentially wound transformer (Fig. 2, not shown). The inputmay be taken from the plate circuit of a preceding valve 30 which may have a choke coil 31, Fig. 4 in its plate circuit, or a resistance (Fig. 5, not shown), or a transformer (Fig. 6, not shown). Fig. 7 shows a modification in which the plate of the second valve 40 is inoperative or is absent. A variable resistance 41 is in this case included between the grid of the amplifier 43 and the filament of the auxiliary valve 40. In Fig. 8, there is also a second amplifier valve 47, which has its grid-filament path in series with the grid-filament path of the amplifier valve 46. The valve filaments are energized by separate batteries or by separate secondary coils on a supply transformer (Fig. 9, not shown), the arrangement being stated to eliminate the hum due to the alternating supply. The grid of the amplifying-valve may be given a positive bias to enable it to work on a straight portion of its grid-current grid-voltage curve.
