Title: Improvements in or relating to the manufacture of knitted fabrics
IPC: D04B9/18
Filed: 1922-10-05
Abstract: 209,190. Stibbe, C. H. D. C. Oct. 5, 1922. Circular machines; knitting, methods of.- A tubular fabric knitted from two or more yarns by continuous circular knitting the fabric in one . part of the tube being composed mainly of one yarn while the fabric in the other part is composed mainly the other or others is obtained by the use of yarn feeds at different levels and different clearing levels for the two sets of needles. Cams are employed to raise the needles of the two sets to clear and take yarn at different levels, the low level feeder being moved to a high level when necessary to prevent the wrong needles from taking yarn therefrom. When the leg of a hose or similar part is being knitted, a cam 1 acts upon long butts 2<a> and short butts 3a of the needles 2, 3 to cause all the needles to clear and take yarn at a high level feeder 4. When the split foot effect is to be made, the cam 1 is moved out by the action of a pattern drum so as to miss the short-butt needles which are then raised bv a clearing cam 5 to take yarn from a low level feeder 6. A few needles take both yarns in order to join the sole and instep fabrics together. The unknitted yarn floats across the inside of the tube and is subsequently cut away. The low level feeder 6 is moved upwards to miss the longbutt needles when required by any well known means. The instep fabric may be horizontally striped.

Title: An apparatus for artificial respiration and pressure regulation during gas anesthesia
Inventor: STANTON PHILIP LOCKLAND
IPC: A61M16/00
Filed: 1951-11-23
Abstract: 714,777. Respiratory appliances. E. & J. MANUFACTURING CO. Nov. 23, 1951, No. 27561/51. Class 81(2) Apparatus for artificial respiration and pressure regulation during gas anaesthesia comprises a device for connection with an airtight container for a bellows of an anaesthetic machine and including a case divided by an airtight diaphragm into an airtight chamber and a chamber open to the atmosphere, said airtight chamber communicating with said container, said diaphragm having a toggle mechanism which actuates a valve to open and close a first passage communicating with a source of air pressure and the airtight chamber, a Venturi tube positioned in the first passage and arranged to withdraw air from a second passage communicating the airtight chamber to the atmosphere via said first passage. A bellows 1 is attached by a T-joint to a conduit between the source of anaesthetic and the mask. An airtight chamber 6 surrounds the bellows 1 and is in communication with an airtight chamber 17 in a pressure regulating device 5. A diaphragm 18 separates the airtight chamber 17 from a chamber 21 which communicates with the atmosphere through a port 35. Compressed air enters the pressure regulating device 5 through an adapter and a valve 29 and when the pressure in the airtight chamber is at a minimum it flows through a venturi tube 30, passages within the wall of the pressure regulating device and past a valve 27 into the airtight chamber 17. The resultant increase of pressure in the chamber 6 compresses the bellows 1 so that anaesthetic is supplied to the patient. When the pressure within the airtight chamber has reached a predetermined maximum (13mm. of mercury above atmospheric pressure), pressure on the diaphragm 18 causes a toggle mechanism to snap over with the resultant closing of the valve 27 and opening of a valve 26 on the same stem 24 which is connected with the toggle mechanism. Air within the airtight chamber 17 is then drawn by the action of the Venturi tube 30 into passages in the walls of the regulating device 5, to a chamber 33 and thence past the second valve 26 to a port 39 connected with the atmosphere and covered by a felt-lined sound-suppressing strip 50. The reduction of pressure within the airtight chamber 17 and the chamber 6 allows the bellows 1 to expand as the patient exhales. When the pressure within the airtight chamber 17 has reached a predetermined minimum, the diaphragm 18 causes the toggle mechanism to snap over in the reverse direction so that the first valve 27 is opened and the second valve 26 is closed. Pressure can again build up within the airtight chamber 17 and chamber 6 as the cycle is repeated. Housings 40, containing spring held plate valves 41 respectively, are provided to keep the pressure within the airtight chamber 17 within a predetermined maximum and minimum respectively.

The duct may also be formed by milling, or otherwise producing, a groove in one side of the strip or bar and closing the mouth of the groove by means of a cover or ribbon soldered or brazed to the edges.

Title: Semiconductor device
IPC: H01L29/68
Filed: 1961-07-31
Abstract: 966,989. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 31, 1961 [Nov. 21, 1960], No. 27670/61. Drawings to Specification. Heading H1K. In a tunnel diode, surface current leakage is reduced by increasing the resistivity, i.e. to above degeneracy of the semi-conductor material where the junction is exposed to the surface. For example in P-type germanium it is stated that by increasing the resistivity from 0.003 ohm cm. (5 x 10<SP>19</SP> impurity centres per c.c.) to 0.03 ohm cm. (less than 10<SP>19</SP> centre per c.c.) in the surface region near a PN junction, then the greater part of the tunnelling current will flow within the main body of the material. The corresponding figures for N-type germanium are 0.001 to 0.01 ohm cm. One method of obtaining such a tunnel diode consists in doping germanium with arsenic until a concentration of 5 x 10<SP>19</SP> impurity atoms per c.c. is reached and then heating this material for thirty minutes at a temperature of 600 C. under a pressure of 10-<SP>7</SP> m.m. of mercury, which reduces the surface impurity concentration to about 10<SP>16</SP>. A narrow junction (less than 150 Angstroms) is then made by allowing to the above N type germanium an indiumgallium mixture. A brief reference is also made to an epitaxial-growth method of making the junction.

Filed: 1926-11-05
Abstract: 261,022. Soc. des Magnetos R. B. Nov. 7, 1925, [Convention date]. Spray carburettors.- To prevent waste of fuel when the engine is rotated by the kinetic energy of the vehicle, e.g. on down grades, a valve controlled by electric current supplied by a generator driven by the engine is provided to automatically cut off the supply of fuel to or from the slow-running nozzle when the engine reaches a predetermined speed. As shown, the outlet from the slowrunning nozzle 2 is controlled by a valve 5 held open by a spring 6 or by gravity, and closed by an electro-magnet 7 which attracts a soft-iron disc 8 on the valve spindle when the engine reaches a certain speed. In carburettors in which the slow-running nozzle also supplies fuel for accelerating, means are provided to prevent the closing of the nozzle when the main nozzle is in action; the means may comprise a cam on the throttle valve spindle acting on a bell-crank lever one arm of which bears against the disc 8 when the throttle is open, or a contact piece on the controlling-gear of the throttle valve may out off the current to the valve controlling the slowrunning nozzle when the throttle is in the normal running position. The Specification as open to inspection under Sect. 91 (3) (a) comprises also modifications in which the valve 5 is operated either by a centrifugal governor driven from the engine, or by a piston operating in a cylinder to which a fluid under pressure is supplied by an engine-driven pump, e.g. a pump employed in connection with the lubricating or cooling system. This subjectmatter does not appear in the Specification as accepted.
