Title: Improvements in or relating to electrolytic plating and anodizing systems
IPC: C25D21/00
Filed: 1956-11-16
Abstract: 812,208. Electroplating and anodizing. PFAUDLER PERMUTIT Inc., [formerly PFAUDLER CO.]. Nov. 16, 1956 [Nov. 18, 1955], No. 35131/56. Class 41. An electrolytic plating or anodizing system comprises a bath and a still arranged to allow electrolyte to circulate from the bath through the still and to return; the still being capable of being subjected to vacuum for evaporating a portion of the electrolyte introduced into the still. An illustrated embodiment comprises plating bath 10, rinse baths 12 and 14, still 24 surrounded by steam jacket 26, separator 40, condenser 38 and vacuum source 36. Rinse water is supplied to bath 14 through pipe 16, to bath 12 through syphon 18 and to bath 10 through syphon 20. The articles to be plated are successively conveyed into bath 10, thence to bath 12 and thence to bath 14. Initial heating of the electrolyte in bath 10 to operating temperature is accomplished by drawing off electrolyte through pipe 22 to steam-jacketed vessel 24 and thence circulating it back to bath 10 through valves 30 and 32, pump 28 and pipe 33. Upon passing current in bath 10 during plating operations heat is generated. To maintain bath 10 at an optimum temperature the vessel 24 is operated as a still at subatmospheric pressure using vacuum source 36. Electrolyte is drawn into vessel 24 from bath 10 through pipe 22 and nozzle 23 by vacuum; a portion of the water is then evaporated and the concentrated electrolyte remaining is withdrawn and returned to bath 10 by pipe 33. The heat of vaporization cools the concentrated electrolyte in vessel 24 and this electrolyte, on return to bath 10, effects cooling thereof. Water vapour from still 24 is drawn by the vacuum through separator 40, where entrained particles of liquid are removed, and thence through conduit 35 to condenser 38. Liquid collected in separator 40 is returned to vessel 24 through trays 44. The distilled water condensed in condenser 38 is returned to bath 14 through pipes 46 and 16 and pump 48.

Title: Improved buttonhole and machine for producing the same
IPC: D05B73/12
Filed: 1928-11-29
Abstract: 317,694. Fairweather, W., (Singer Manufacturing Co.). Nov. 29, 1928. Buttonhole sewing-machines, needles, vibrating laterally.-A buttonhole machine has a needle vibrating in the direction of the slit to simulate the stitching of a hand-sewn buttonhole. The stitch - forming mechanism and work-clamps are held stationary during the interval between two reciprocations of the needle. The machine is of the type described in Specifications 197,463, 197,629, and 198,628, and the stitch-forming mechanism is similar to those described in Specifications 15048/15 and 179,278, except that the present mechanism includes also means for vibrating the needle in the direction of the buttonhole slit. The usual rotary and reciprocating -needle-bar 28 is journaled to the bushing 29 and carries the yoke 30 and carrier 32 for the. needle 5. The carrier 32 has two spaced parallel plates 33, 34 of which the plate 33 is held by a spring 35 against the yoke 30. When the needle carrier 32 is in the slit-stitch position on the pin 31 as shown in the full lines, Fig. 14, the carrier may have a limited tilting movement on the pin 31 as shown in dotted lines, Fig. 8. When the carrier occupies the depthstitch position, the plate 34 engages the lug 30<1> on the yoke 30 and is held rigidly in the vertical position as shown by the dotted lines in Fig. 14. The carrier 32 is moved along the bearing pin 31 by the lever 36 pivoted on the cross-bar 38, and the bell-crank lever 50 vibrates the needle transversely of the slit. The needle is vibrated longitudinally of the buttonhole by the following mechanism. A block 45 carries a pair of links 59 carrying the cam-plate 60 yieldingly urged upwards with a link 59 in engagement with a pin 62. The plate 34 of the needle carrier 32 has a tooth 63 which, when the needle is rising, engages the cam-plate 60 as shown in dotted lines in Fig. 8, to tilt the needle carrier, thus shifting the needle along the slit in a direction opposite to the direction of feed. This motion wipes the needle over any cut thread-ends in the slit and neatly covers the cut material after the manner of the hand-sewn buttonhole. The needle-thread is carried forwardly and bent over the cut edge at a point opposite the ensuing depth-stitch. After the needle rises from its depth-stitch descent, the feed of the work takes place and the lateral vibration of the needle to the slit-stitch position lays the thread in a vertical plane normal to the slit as shown in Fig. 22, so as to concatenate the thread in the slit to cover the cut material entirely, even though the stitching is approximately as coarse as in hand-sewn buttonholes.

[Class 126.] In a gas cooking-oven having a flue passage 18 extending from an opening 21 at the front of the oven and between spaced inner and outer crown plates 11, 10, to an opening 17 at the rear, the flue 18 is formed as a channel in the plate 11 having mounted over it a cover plate 22 formed with or carrying a seat 28 for a valve 36, the gases passing by this valve to the space over the cover plate 22 and thence to the outlet 17. In the construction shown, the valve seat 28 is formed as a separate member, having a flange 29 projecting into a channel 26 which surrounds the opening in the cover plate 22 and contains sealing composition. The valve seating is inclined, as shown, and secured by a screw 31 to the top plate. The valve 36 is adjusted by rotating a screwed stem 35 on which it is mounted, rotation of the valve being prevented by an arm 38 on it engaging a stop 39. A gas outlet 14 is also provided at the bottom rear part of the oven, the gases passing up a flue passage 15 formed by a rearwardly dished part of the outer rear wall 12 of the oven and a cover plate 16. An enamelled sheetmetal plate 4 is secured behind the opening 14, and two small flue outlets 9 are formed behind it in the rear wall.

Abstract: 901,450. Refrigerating liquids. PORMOR Ltd. Aug. 5, 1958 [Nov. 26,1957], No. 36748/57. Class 29. Liquid, e.g. draught beer, is cooled by a compression system, the maximum suction pressure of which corresponds to an evaporating temperature which is as close as possible to the desired liquid temperature, the expansion valve being held wide open until the liquid temperature reaches a predetermined amount above the maximum evaporating temperature and then gradually closing so that the evaporating temperature falls as the liquid temperature approaches its desired final temperature, During this last stage, the predetermined difference of temperature between the liquid and the evaporator is maintained constant and is such as to be the lowest at which complete evaporation occurs. As shown, beer is supplied to one or both of two thermally insulated chambers 10, 11 from a plurality of sources selectively and can be led therefrom selectively to dispensing points. The chambers are cooled by an internal or external evaporator coil 24 and may have vertical internal baffles. Preferably, the inlets and outlets are so located that some beer is left in the chamber when the supply stops and sediment is trapped. The compressor 25 is controlled by the outlet temperature of the beer detected by a thermal element 61. Evaporators 24 for the two chambers are connected in parallel and have their own expansion valves 30, 31 controlled by thermal elements 55, 56 responsive to suction temperature to ensure complete evaporation in the evaporators. An element 59 stops the compressor when a minimum suction pressure is attained. For heating the liquid, the supply of refrigerant to the expansion valves can be interrupted by solenoid-operated shut-off valves 32, 33 and hot gas can be supplied direct to the evaporators from the compressor discharge by way of solenoid-operated valves 34, 35 and heaters 28, 29.
