Title: Coating metal with nickel
IPC: C23C16/16
Filed: 1955-10-03
Abstract: 783,380. Coating metal with nickel. COMMONWEALTH ENGINEERING CO. Oct. 3, 1955, No. 28037/55. Class 82(2) Metals, especially iron and steel, are coated with nickel by decomposition from the carbonyl after the surface has been treated by exposure to carbon, monoxide contacting with unoxidized nickel, with a resultant increase in adherence of the coating. An apparatus for the purpose comprises a glass vessel 1 with a removable stopper 3. A vacuum is set up by extraction of air through valve 11 and then the carbon momoxide is admitted at 37. A layer 19 of nickel on a support 17 is heated by an induction coil 35 and contacts the carbon monoxide before it meets the object 16 to be plated, also heated inductively by a coil 33. The carbonyl may be admitted through a pipe 39. Water jackets 23, 27 permit cooling of the nickel and object. In use, the nickel is heated to 1200‹-1525‹F. and the object about 500‹F. and less than 750‹F. The carbon monoxide flow is established and then nickel carbonyl is also admitetd. The temperature of the object is then allowed to fall to a normal plating temperature (250‹-450‹F.) and the nickel to less than 100‹F. for the actual coating Step

Abstract: 817,515. Measuring continuous lengths. TELEVISION AUDIENCE MEASUREMENT Ltd. Oct. 15, 1956 [Oct. 13, 1955], No. 29175/55. Class 42 (2). [Also in Group XX] Apparatus for reading indications recorded on an elongated track (e.g. a tape) at different positions relative to a datum the length of the track differing from a predetermined length, comprises moving means for moving the track past an index, indicating means controlled by said moving means and adapted to indicate the position relative to the datum of that indication on the record track which is adjacent the index and means also controlled by the moving means for automatically moving the index relative to the apparatus whereby errors in indicating the position of an indication on the track due to the differences between the length of the track and said predetermined length are compensated. The apparatus may be used to read the indications recorded on a tape by the device described in Specification 781,084, [Group XIX], and, as shown, includes spools 2, 3 between which the tape 6 is fed across a bed plate 10 and a sprocket roller 7, which is geared to a time indicator 8 through a releasable clutch. The tape passes under a cursor 9 carried by a slidable member 11 so that cursor 9 is capable of movement parallel to the tape. Member 11 is connected to a slide 29 by a pivot 30, and the slide is carried by a bar 24, one end of which is pivoted at 25 to a bar 13 and the other end of which can be clamped at 28 to a quadrant 26 provided on the bar 13. This bar 13 is slidable at right-angles to the tape in a guide 14 and is driven by gearing from the indicator 8. In use, sprocket 7 is rotated by knob 34 until a stop at the end of bar 13 remote from the quadrant 26 abuts a fixed part, the cursor 9 then being directly above the axis of bar 13. Sprocket 7 is then rotated further until indicator 8 registers the time of the " off " mark on a tape which is about to be placed on the apparatus. The clutch between sprocket 7 and the indicator 8 is then released and tape 6 is placed in the apparatus with its " off " mark under the cursor 9. The clutch between sprocket 7 and indicator 8 is then reengaged and the tape is wound on to a spool 2 until the time of its " on " mark is shown on indicator 8. If the tape record has departed from the nominal scale to which the indications were made during the recording thereof, the " on " mark will not be under cursor 9. Therefore, arm 24 is pivoted to move cursor 9 into registry with this " on " mark and is thereafter clamped. The apparatus is now set up and tape 6 can be read, any departure from the nominal scale being corrected by movement of bar 13 as the tape 6 is moved.

Abstract: 325,015. Marshall, R. April 30, 1929. Steam traps. - To prevent pitting and scoring of automatic discharge valves for steam traps, the co-acting valve surfaces are surrounded by a finely perforated cylinder, and a masking device, associated with one of the valve surfaces, slidably fits the cylinder, delaying passage of the fluid until the surfaces have been separated to a certain extent, also preventing direct impingement of the fluid upon one or both surfaces. Float - controlled discharge valves for steam traps are shown in Figs. 4 and 6, the floats 31, which rise and fall in the casings 30, surrounding stationary discharge pipes 32 and being formed with finely perforated inner walls 41 to impede passage of solid particles. In the form shown in Fig. 6, the valve member 54, closing the outlet 34, remains seated until, as the float descends, a cross bar 56 in the foot 57 of the float, engages the flanged end 59 of the valve stem. Until the valve has been thus opened, a skirt or flange 51 depending from the outlet member 52 masks the perforations 47, preventing passage of fluid. A cross bar 55 in the outlet member guides the stem. In the modification shown in Fig. 4, piston members 36, 37 on the valve stem slide in a closed cylinder 38, delaying passage of the fluid until ports 48 are uncovered. This device supplements the action of the skirt 40 masking the perforations 47. A bore 49 in the valve stem allows passage of fluid to equalize pressures in the chambers 33<1>, 38<1>.
