Title: Improvements in or relating to devices for measuring the rate of consumption of oxygen
IPC: A61B5/093
Filed: 1937-06-29
Abstract: 497,494. Gas meters; valves. JONES, H. M. June 29, 1937, No. 18061. [Classes 54 and 135] [Also in Group VI] Apparatus for measuring the rate of consumption of oxygen which is particularly suitable for use as a respiratory appliance comprises a bellows 19 which is charged with a measured amount of oxygen or oxygen containing fluid and then collapses at a rate dependent on the rate of consumption. One end of the bellows is fixed with respect to a frame 15 whilst the movable end 38 is carried by a pair of longitudinally movable members 43, 44 which reciprocate in guides 48, 49. The fixed end of the bellows 19 is second to a soda-lime container 18 mounted on the frame and communicating by a passage 79 having a valve 78 with a measuring chamber 17. A mouthpiece 23 is connected to breather tubes 20, 21 controlled by a cock 27. One of the passages from the latter opens into a perforated member 30 exposed to a large surface of soda-lime whilst the other 29 is connected to. a motor-driven pump 32 which draws oxygen from the bellows through a screen 34 and a pipe 35. The movable end 38 of the bellows 19 has a vent opening 40 normally closed by a valve 41 carried by a flexible arm 42 but opened when the bellows expands sufficiently to tighten a chain 37 anchored to a plate 36 and to the valve 41. The end plate 38 is carried by a crosshead 39 clamped to the rod member 43 by a screw 45, but mounted so as to slide and pivot with respect to the other rod member 44 so that binding of the cross-head is prevented. One end of the cross-head has a slot 47 embracing a bolt or pivot 46. The guide 48, 49 are of tubular form and are secured to the frame 15 by screws 53. The ends of the cross-head pass through opposed slots 50, 51 in the guides. Guide blocks 54 ... 57 provided with antifriction rollers 59 for the rods 43, 44 are secured within the guides 48, 49 by the screws 53. A valve device 68 having a restricted passage 74 and 11 check valve 76 is screwed through a wall 72 of the measuring chamber 17 so as to have a small amount of play with respect to an opening 69 and is clamped against this wall by the squared end 64 of an oxygen bottle 16 under the action of a pressure screw 73. The head 64 has an opening 65 and a valve 66. Gaskets 70, 71 are interposed between the wall 72 and the head 64. If the pressure in the chamber 17 registered by a gauge 77 is too great, oxygen may be released by slackening the screw 73. The cock 27 is first turned so that the patient may inhale and exhale through the tube 20, and afterwards so that both passages from the cock are open. The measured amount of oxygen is then delivered to the bellows by opening the valve 78. A pen arm 61 on the rod 43 records the bellows movement on a card driven slowly downwards by clockwork.

Filed: 1974-04-25
Abstract: 1501114 Semi-conductor devices RCA CORPORATION 18 April 1975 [25 April 1974] 18165/74 Heading H1K A patterned layer of P-type silicon with vertical or outwardly sloping edges suitable for the gate electrodes of IGFETs or inter-connections in an I.C. is formed by first diffusing donor impurity from a coating on the surface into a continuous layer of silicon to form N regions defining the edges of a P-type pattern and then exposing the entire layer to a chemical etchant, such as aqueous hydrazine or a solution of potassium hydroxide and propanol, capable of dissolving N-type but not P-type silicon. As described, the continuous layer, of polycrystalline silicon, is first deposited to a thickness of 8000  on a thermal oxide coated monocrystalline silicon wafer by thermal decomposition of silane. In one embodiment the entire layer is rendered P-type, either by adding diborane to the silane or by acceptor diffusion after deposition. Then donor-doped silica is deposited over it by reaction of silane and phosphine with oxygen and photo-etched to define a pattern. Alternatively a pattern of undoped deposited silica is formed and phosphosilicate glass formed on the entire surface by deposition or exposure to phosphorus oxychloride. In an alternative method, in which the deposited silicon is intrinsic a patterned donor doped layer can be formed as above and boron doped silica deposited overall or borosilicate glass formed by exposure to boron in an oxidizing atmosphere. Alternatively a layer of boron-doped silica is first deposited by reaction of silane and diborane with oxygen, then patterned, and phosphosilicate glass formed as before. In all eases subsequent heating causes the impurities to diffuse into the silicon to define the P-type pattern.
