Abstract: 201,646. Craymer, H. J. May 3, 1922. No Patent granted (Sealing fee not paid). Breaking and scutching apparatus.-In the decortication of fibrous material the material is fed step by step through devices comprising needles which are during the feeding movement reciprocated laterally to pierce the material and also longitudinally along the material. The machine may also comprise a device operating in a similar manner to brush or scrape the material after it has been pierced. The piercing-devices A, B, Figs. 2 and 6, comprise a pair of opposed plates 17 carrying a series of needles 18 arranged in irregular lines. The needles pass through perforated plates 19 connected to the plates 17 by screws and nuts 21 but held apart from them by springs 22. The plates 19 have studs 23 and corresponding holes to ensure correct registration. One plate 17 is secured to a base plate 10 reciprocated by a crank 3. The other plate is connected by rods 25 sliding through the plate 10 to arms 28 pivoted to the main frame. Rotation of the crank first causes the plates 19 to press on the material and then the needles to pass through the plates into the material. Movement of the plates takes place both laterally and longitudinally. The plate 10 is connected by pivoted links 13 to a yoke 14 carrying the ram 15 of a force pump 16 whereby water is sprayed through pipes 31 when the plates 17, 18 are separating. The needles may be soldered to the plates 17 or be of staple form secured by a second plate 17<b>. The needles of the device B are finer and closer together than those of the device A, and the throw of the crank is reduced, the speed of the crank shaft being increased. The brushing or scraping device C comprises plates 58 with transverse or zig-zag rubber or other bars 61. The means for operating this device are similar to that for operating the piercing-devices. The crank shaft is arranged 180‹ in advance of the crank of the device B. The material is fed by rollers or into a holding-device comprising a bar 32 and a counterweighted plate 33. Rollers 36 are provided between the devices A, B, and C. The material is delivered on to an inclined belt 41 and passes out through rollers 44. The expressed juices drain into a sump. The rollers 36 and delivery devices are rotated intermittently by ratchet wheels operated by suitable links from the central crank-shaft. The various devices may be suspended from the main frame by springs 57. The number of devices may be varied and the scraping &c. device may be omitted.

Title: Fire extinguishing device
IPC: A62C37/12
Filed: 1924-05-26
Abstract: 229,539. Woosnam, A., (Ohio Automatic Sprinkler Co.). May 26, 1924. Sprinklers, automatic.- A sprinkler valve is released by a thermostat responsive to a predetermined rate of rise of temperature. A diaphragm C is held between the halves D, D<1> of a vessel containing gas. The half D<1> is thicker than the other so that the air contained therein is more slowly heated and the greater expansion of the air in the half D causes movement of the diaphragm C, which moves a lever I pivoted at S, releasing a crank J on a pintle J<1>, struts L, K, and the, valve N. A vent V is provided in the diaphragm C to allow the pressures in the two halves D, D<1> to equalize on a slow rise of temperature, and when an excessive temperature is reached slowly a stiff diaphragm C<1> is moved to release the sprinkler valve by arms H, H<1> connecting it to the diaphragm C. The arm H<1> engages a slot in the arm H by a hook, so that there is no interference with the normal,action of the diaphragm C. A plate G acts as a stop to the diaphragm C. The crank J passes through a flexible diaphragm 2 supported by a metal washer below and acting as a sealing means. A looking clip M pivoting on the face of the strut K facilitates assembly. A casing T rupturable by the escaping fluid may be held lightly on a ledge of the base O by a cement softened by heat.

Title: A Process for Diffusing Impurities in In-As Crystal
IPC: H01L21/225
Filed: 1967-03-20
Abstract: 1,156,602. Semi-conductor devices. MATSUSHITA ELECTRONICS CORP. 20 March, 1967 [28 March, 1966], No. 12981/67. Heading H1K. One or more group II elements are diffused as impurity into an In As semi-conductor monocrystal through a surface layer of silicon oxide between 0À8 and 1À5 Á thick. Such a layer allows the dopant to pass through but prevents the formation of the deleterious polyorystalline layer which is produced when such dopants impinge on an exposed semi-conductor surface. The effect of polycrystalline contamination is to destroy the optically flat property of a previously polished crystal surface and it is thus a bar to the production by diffusion of the optically flat PN junctions required in injection lasers. After formation of the oxide, which may be SiO or SiO 2  deposited on the crystal surface by vacuum deposition or pyrolytic decomposition, the subsequent diffusion is by a conventional vapour phase process performed either in an open tube or a closed chamber. In the latter case (Fig. 3, not shown) the parts of the chamber containing dopant and the crystal to be doped lie within separate tubular heaters so that they may be brought to appropriately different temperatures. The Group II impurity may be Zn, Cd or Hg and its introduction may merely change the impurity concentration in the In As crystal or reverse its type to produce a PN junction; for example in transistor production the invention may be employed to form the base region of an NPN structure or the emitter region of a PNP structure.
