Title: Improvements in or relating to the manufacture of hydrocyanic acid
IPC: C01C1/12
Filed: 1954-01-12
Abstract: A hydrogen cyanide-containing gas mixture obtained by interacting carbon-containing gases, e.g. carbon monoxide, and ammonia is freed from ammonia by washing with a saturated aqueous solution of hydrogen cyanide, and the ammonia recovered from the washing liquor by treatment with a cation exchanger.  The washing liquor may then be recycled.  The ammonia may be extracted from the cation exchanger by electrodialysis, heating, or treatment with acid, e.g. nitric acid, followed by treatment with a base such as lime, and returned to the synthesis process. Hydrogen cyanide may be recovered from the washed gas by spraying with a liquid condensing agent which is immiscible with and which has a density substantially different from that of liquid hydrocyanic acid, e.g. decalin.  Residual hydrogen cyanide may be recovered by absorption in activated carbon.  The remaining gas may be washed to remove carbon dioxide, passed through activated carbon at low temperatures to remove hydrogen, and the remaining carbon monoxide returned to the synthesis process.

Filed: 1916-01-18
Abstract: 103,168. Roberts, A. Jan. 18, 1916. Coke ovens.-In a gas-fired coke oven, particularly of the kind described in Specification 1570/15, means are provided for heating the air for combustion in the hollow oven walls consisting of independent hollow walls built up of blocks in a similar manner to the oven walls described in the above-mentioned Specification and arranged between the walls of the ovens in such a manner that they are free to expand. The waste gases are led to a regenerator in the base of the oven structure where the air is preliminarily heated before passing to the hollow wall arranged between the ovens. As shown in Fig. 1, the air-heating walls 30 are arranged between the oven walls 22, 23 and separated therefrom by spaces which allow the walls to expand when hot. The walls 30 are built up of recessed blocks in a similar manner to the walls 22, 23 to provide a network of interconnected air passages. The air supplied to the lower end of the wall 30 is previously heated in regenerators situated, as shown in Figs. 8 and 10, in the base of the oven structure. These regenerators comprise hollow air-heating walls 39, 40, 41 built up of alternate rows of plain and recessed blocks, and intermediate flues 42 and 43 for waste gases. Air is supplied to the ends of the hollow walls 39, 40, 41 from pipes 61, 63 and passes upwardly into passages 44, 45, 46, 49, 50, Fig. 16, and finally enters the uptake 56 leading into longitudinal flues 55 communicating with the lower ends of the walls 30. The waste gases from the oven walls pass downwardly into flues 24 connected at their ends by damper-controlled passages to down-comers 57, and thence through openings 58 to the passage 42 communicating with the flue 43 by openings 59. After passing upwardly through the walls 30, the air passes through damper-controlled passages 32, Fig. 17, to burners situated at the top of the oven walls and connected to the gas-main 28 by pipes 29 provided at the top with sight-openings 73 preferably closed by blue glass. The burners are built up of circular sections 27, 68, 69, 70, the parts which engage being recessed and tapered. (For Figs. 1, 8, 16, and 17 see next page.)

Title: Machine for making wired box parts
IPC: B27M3/36
Filed: 1938-01-11
Abstract: 488,833. Making wired box parts or blanks. ROSENMUND, A. L., and STAPLING MACHINES CO. Jan. 11, 1938, No. 881. [Class 18] In a machine for forming a bight B, Fig. 11, in a flexible binder secured to a box part or to a series of such parts constituting a blank and driving the end of the binder into the box part to perpetuate the bight, the box part is fed through the machine by automatic conveyer mechanism. The blank &c. is wired and stapled on a machine similar to that described in Specifications 220,605, 248,735, [both in Class 18], or 413,212, [Group VII], and it runs from the endless-belt conveyer 1, Fig. 5, of that machine between two horizontal endlessbelt conveyers 10 which are spring-pressed against the edges of the blank. As the latter advances it trips a lever 54 which, acting through levers 60, 61, 47, slides a frame 42 to the right and allows an intermittent clutch 35 to engage to place a rotating arm 36 in communication with the power supply. As arm 36 starts to rotate, a lever 38 connected thereto pushes a frame 31 carrying the bight forming mechanism along with the blank. This latter mechanism is similar to that described in Specification 409,995 and it is released in order to make one complete cycle by a pivoted dog 63 which is moved to the release position by the action of lever 61. After the bight-forming &c. mechanism has operated, the frame 31 contacts with a projection 52 on the frame 42 to push the latter to the left and so disengage the clutch, and a spring 34 brings the frame 31, which runs on rollers 32, back to its initial position. The box blanks are supported underneath by rods and on top by presser bars carried by the frame 31 ; and the inner reaches of the conveyer belts 10 may be recessed to allow the mechanism to operate near the edges of the box parts.

Title: Improvements in or relating to the manufacture of endless friction facings
IPC: F16D69/02
Filed: 1937-01-12
Abstract: 488,711. Moulding friction facings. RAYBESTOS-MANHATTAN, Inc. Jan. 12, 1937, No. 942. Convention date, May 31, 1936. [Class 87 (ii)] [Also in Group VIII] Endless friction facings for clutches &c. are produced by folding a strip of fabric, treated with a thermosetting binder, longitudinally into chevron form, winding the strip spirally so that the convolutions internest, and subjecting the body to pressure and heat to compact the convolutions and harden the binder. A flat strip 1 of woven fabric is drawn through a bath 7 of liquid binder such as rubber or synthetic resin, thence through a drying chamber 12 and rolls 13, 16 which give it a longitudinal curvature and a V-shaped cross-section and is finally wound loosely on a mandrel 18. The mandrel has flanges, one of which is detachable to facilitate removal of the coiled annulus. The annulus 30 is then compressed in a hydraulic press, Fig. 7, which may be heated to harden the binder. Alternatively the element may be cured in a separate operation. In a modification the strip may be formed with a double chevron cross-section or the strip may be wound with its concave side outwards. In the consolidated element the two arms of the chevron are brought into substantially parallel position and the element becomes a flat annular disc. Countersunk rivet holes may be drilled in the disc. The strip fabric is woven from asbestos yarn and, as shown in Fig. 4, the central warps 3 may be spaced apart to weaken the central fold. The yarn may be a mixture of asbestos with cotton, wool, &c. and may be reinforced with metal wires 6. The strip may also be cut on the bias from a sheet of fabric.

Title: Image reader
Inventor: TABATA MASAMI
IPC: F21V8/00
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To secure the thickness of a holding means which provides sufficient mechanical strength by forming a polygonal shape of >=5 sides as the shape formed by connecting the respective vertexes of at least partial section of a lighting means by straight lines. SOLUTION: A lighting part consists of LEDs 7 as a read frame type spot light source provided at both ends, a light guide body 8 as a columnar light guide means formed of a light-transmissive member such as acryl resin so as to make the light of the LEDs 7 linear, and a housing 9 which has a hexagonal shape obtained by connecting the respective vertexes of section for positioning and holding the LEDs 7 and light guide body 8 by straight lines. Thus, the shape formed by connecting the vertexes of the section of the housing 9 of the lighting part by the straight lines is made hexagonal, so the sectional area of the housing 9 can be made small to secure a frame of thickness which can have sufficient mechanical strength.  Further, the lighting part sits stably on the frame, so the optical axis can be prevented from shifting, and variance in illuminance on a document read line among products can be suppressed.

Title: Semiconductor device and its manufacture
Inventor: KADOMURA SHINGO
IPC: H01L23/522
Filed: 1994-01-06
Abstract: PURPOSE:To provide the construction and manufacturing method of a semiconductor device with which the etching of a contact hole having minute dimensions and a large aspect ratio can be realized with good reproducibility and uniformity. CONSTITUTION:When a contact hole 7 is formed through an SiO2 system interlayer insulating films 2 and 5 by etching, a wide dummy region 5a is also etched. An etching stopper layer pattern 3a is formed in the part of the interlayer insulating film positioned in the thickness direction beforehand in order not to expose a lower layer wiring 1 in the dummy region 5a. With the progress of the etching of the dummy region 5a, oxygen is released into the etching atmosphere. Therefore, the deposition of excessive CF system products is controlled and side wall protective films can be formed under optimum conditions. With this constitution, the contact hole having an excellent shape can be formed and, further, the particle contamination can be suppressed.
