IPC: H04R1/12
Filed: 1933-04-29
Abstract: 418,620. Mouthpieces; sanitary and hygienic devices. COLASSI, W. L., Mark Lane Station Buildings, London. April 29, 1933, No. 28372. Divided out of 402,444. [Class 40 (iv).] A telephone mouthpiece comprises a sound passage, a perforated platform disposed at or adjacent the end of the sound passage nearest to the microphone unit and a chamber, primarily for disinfectant, in the wall of the sound passage, said chamber being disposed wholly or partly in front of the perforated platform and communicating by relatively long and narrow passages with the sound passage behind the perforated platform. The construction described with reference to Figs. 1-6 (not shown), is identical with that described with reference to Figs. 7-12 of Specification 402,444 whilst a modification of such a construction formed in one piece is also described, Fig. 7 (not shown). Fig. 9 shows a construction of two - part mouthpiece for a pedestal type telephone in which one part 20 is threaded at 22 to screw into the microphone cover and at 23 to engage an internal thread 24 on the second part 21. The part 20 is formed with perforations 26, a circular groove 27 and slant passages 28 countersunk at 29 whilst the part 21 has an imperforate flare portion 30, the back end of which is adapted to enter the groove 27, and a chamber 31 adapted to be packed with solid disinfectant, the vapour from which passes through the passages 28 and perforations 26 into the sound passage m. If desired, straight passages may be substituted for the slant passages 28. According to a modified construction, Fig. 12 (not shown), the perforated platform is formed across the inner end of the flare 30 instead of on the part 20, this latter part having a large diameter central hole formed with a ledge adapted to receive and be engaged by the platform. A modification of this construction is described, Fig. 14 (not shown), in which the slant passages 28 are dispensed with and the central hole in the part 20 is made slightly larger so as to leave a narrow annular passage surrounding the end of the flare 30. Figs. 15 and 16 show constructions in which the flare 30 is formed partly on the part 20. In the form shown in Fig. 15, slant passages 28 are employed and the outer periphery of the flare portion on the part 20 is cylindrical so as to receive a ring-shaped mass of solid disinfectant before the parts are screwed together. In the form shown in Fig. 16 which employs straight passages 32, a larger capacity chamber is obtained, but the solid disinfectant has to be formed in two or more pieces to enable it to be placed in position. Breather holes may be provided leading from the chamber 31 to the atmosphere.

Abstract: 1,152,489. Transistors. INTERNATIONAL BUSINESS MACHINES CORP. 24 June, 1966 [30 June, 1965], No. 28385/66. Heading H1K. A field effect transistor comprises first and second semi-conductor regions of one conductivity type separated by a cup-shaped third region of the opposite type and an insulated gate electrode over the rim portion of the third region controls current between source and drain electrode on the first and second regions. Fig. 1 shows such a device produced by diffusing boron through an aperture in oxide layer 20 in phosphorus doped N-type silicon body 12 and then diffusing in phosphorus through the same aperture so that cup-shaped P-type region 14 underlying N-type region 18 results; surface concentrations and layer thicknesses are quoted. Alternatively, the layer structure may be produced by epitaxial deposition into a cavity. Source 24, drain 22 and insulated gate electrode 26 are provided, using molybdenum, aluminium or other metal. If desired, heat treatment of the gate electrode in the presence of the oxide layer may be performed after the diffusion processes which result in boron atoms diffusing into the oxide and phosphorus atoms accumulating under the oxide, thus providing a narrow N-type channel at the rim of the P-type cup-shaped region 14; the arrangement can thus provide either a normally ON or a normally OFF field effect transistor. A plurality of transistors in a single wafer may be made by simultaneous diffusion into a plurality of apertures, the processes being controlled to provide both ON and OFF types of devices simultaneously. In another embodiment (Fig. 7, not shown), an ohmic electrode is provided on an extension of the P-type zone 14 (without any conducting surface channel region) so that the device may also be used as a bi-polar transistor, region 14 constituting the base zone.

[Also in Division E1] Concrete or plaster mouldings of an improved surface finish, e.g. large concrete panels, with an exterior smooth, textured or patterned concrete surface and a plaster interior surface, or panels with two smooth plaster surfaces and which may be provided with reinforcement or cored with insulating material such as polystyrene, wood wool or foamed concrete, are produced by casting in a preferably vibrated mould in contact with a membrane 4, e.g. of rubber or plastics, which is extendable and flexible at atmospheric temperatures and which is drawn into the mould form by a vacuum source 7, which vacuum is released after the material has set, and may be replaced by a higher than atmospheric pressure, to facilitate release from the mould. The mould sides are preferably hinged to the base and a panel may be produced by using a pair of open-topped moulds (Figs. 5 to 7, not shown), the bases (1) whereof are pivoted into the vertical closed position and vibrated after each mould has been filled. Additional moulding material may be added between each mould. Hooked lifting rods may be incorporated into the panel. The inner mould surfaces are preferably permeable to air and water, e.g. of wood, and the exterior mould surfaces impermeable, e.g. of varnished wood, and the membrane 4 may vary from completely impermeable to a high degree of permeability, e.g. interconnected cell foamed latex or, with an impermeable mould, the surface of the membrane 4 adjacent the mould may be permeable or roughened to facilitate the application of vacuum. Retarder additives, e.g. sugar solution, may be introduced into the membrane to produce a roughened concrete surface finish upon subsequent brushing. A template may be arranged between the mould base and the membrane 4. The membrane 4 is preferably sealed to the mould base 1 between a pair of air inflated tubes (13) (Fig. 8, not shown) and is retained around a similar pair of tubes by a third inflated tube (15) (Fig. 9, not shown) when used for more than one adjacent mould. The membrane 4 may be allowed to remain on the moulding during the curing period and to effect protection during storage and transport. The membrane employed is preferably extendable from 1000% upwards and capable of being drawn into the mould under negative pressure of 2 to 28 inches of mercury.

Variable-speed and reversing gearing comprising a set of worms 7 - - 10, Fig. 2, slidable on a driving-shaft 20 and adapted to be enmeshed alternatively with a nest of driven worm-wheels 11 - - 14 is operated by a single rod 4 which turns and also slides. The shaft 20 is supported in a bracket 17<1> supported on a pair of toggle links 18 articulated to shoes 19 which latter normally lodge in transverse slots 21 in a fixed frame 22. In gear position, this bracket 17<1> is locked by pins 17 projecting through holes in a laterallyslidable plate 15 which carries the worm-wheels. As shown in Fig. 1, the worm-wheels 11 - - 14 slide together on a differential sleeve 1 and the nest as a whole drives forwardly through a pawl 32 and rearwardly through a pawl 33. When the speed is to be changed, a main driving clutch is disengaged and the rod 4 is turned so that arms 5 upon it through links 6 withdraw the shoes 19 from the grooves 21. At the same time the bracket 17' falls and the pins 17 are disengaged. The rod 4 is then thrust longitudinally carrying with it the bracket and set of worms, the shoes 19 sliding in a long groove. This longitudinal movement through a bell-crank 23, Fig. 3, moves the plate 15 and nest of worm-wheels transversely. When the proper worm is under its worm-wheel, a turning back of the rod 4 straightens up the toggles 18 and holds the worm gearing firmly in mesh. The pitch of the worm 7 for reversing is of opposite hand to the others.
