Title: Improvements in and relating to sewing machines
IPC: D05B71/00
Filed: 1943-07-01
Abstract: 564,468. Sewing machines. UNION SPECIAL MACHINE CO. July 1, 1943, No. 10661. Convention date, Nov. 9, 1942. [Class 112] Lubricating reservoirs.-In a sewing-machine of the lockstitch type, lubricant is fed from a reservoir 94 in the standard 11, to the raceway of each vertical rotary hook and to associated parts. The supply may be shut off by a valve, and adjustable regulating means are provided. The supply pipe 106 being long and substantially vertical, air contained in the lubricant bubbles back to the reservoir. Curves 124 in the pipes feeding the hook parts 38, 39, allow longitudinal adjustment of the hook shafts towards, or away from each other. A further small reservoir of lubricant is contained in each chamber C at the base of a hook shaft for lubricating escapement mechanism 84, 85, actuated by an eccentric 86 to rock a vertical shaft upon which a finger is oscillated to carry its end into engagement with a projection on the bobbin carrier for the purpose of turning the latter slightly against the frictional drag of the rotary hook. Another supply of lubricant is contained in the base of the standard 11 to be dipped into by a gear 34 and rocking arm 26. A dipstick 135 is provided. The hook shafts 42 are driven by spiral gearing 40, 41 through a shaft 35, and supported in brackets 43 which are adjustable towards or away from each other. The pipes 108 supply lubricant to inlets 60, Fig. VIII, each leading to a chamber 63, 64. From this chamber, during rotation of a hook shaft, lubricant flows through one or more holes 74 to lubricate a raceway 59 which supports a stationary bobbin - holder 57. An annular channel is arranged under the frusto-conical hook-shaft head. An oil sling 72 prevents oil from leaking outside a cover-plate 65. A spiral groove 75 allows some lubricant to pass downwards and lubricate the bearing for the hookshaft and the teeth of the gears 40, 41. During rotation the sense of the groove 75 tends to cause lubricant to be pumped upwards. The pitman 85, used to oscillate a vertical shaft as described above, is a tight fit on a pivot 88, but a loose fit on its driving eccentric 86. An oil passage leads to the vertical shaft and seeps down to the chamber C. Some oil will work upwardly into a bearing 51. The reservoir 94 may be of sheet metal or plastic material and have an opening 100. A tapered dipstick 101 may be provided. A spring-pressed valve may be operated by a hand wheel 127 to admit, or shut off, lubricant supply to the pipe 106, which may be of brass or plastic material. The lubricant flow to the inlets 60 is controlled'by adjustable needle valves in a manifold 112. The lubricant in 94 is preferably of a light stainless type. That in the base of the standard is preferably heavier.

Title: Process of preparing a uniformly palatable soybean protein concentrate
Inventor: SAIR LOUIS
IPC: A23J1/14
Filed: 1959-04-01
Abstract: A uniformly palatable soybean protein concentrate food additive is prepared by subjecting mechanically divided soybean material containing natural water-soluble ingredients to the dissolving action of water at a pH in the vicinity of the isoelectric pH of the protein content of the material, separating the solids from the resulting solution, and removing substantially all the beany-taste ingredients therefrom by washing the separated mass of solids with water.  The separated mass of solids may be further treated by elevating its pH to a value not over 10,5 by addition of an alkaline material and/ora buffering compound which is or becomes edible.  The thus treated mass may then be suspended in water at a pH not below 6, heated to a temperature of from 100 to 180 DEG F. to render the suspended solids dispersible and the suspension a translucent viscous mass which may be spray dried.

Abstract: 843,313. Bearings. CARRIER ENGINEERING CO. Ltd. April 9, 1958 [July 8, 1957], No. 11243/58. Class 12 (1). [Also in Groups XXVI and XXXV] A pump for use in an installation in which it is exposed to a metal plating action comprises an impeller shaft bearing having co-operating stationary and rotary members, one of the members being tapered so that relative movement of the stationary and rotary members occurs automatically to compensate for plating of the bearing surfaces, thereby preventing seizure of the bearing. The pump shown in Fig. 2 is used in an absorption refrigerator for pumping an absorbent, such as a solution of lithium bromide, the bearings 107, 108 being lubricated by absorbent taken from the pump discharged through lines 116, 117. Copper dissolved from copper-containing parts of the refrigerator by the solution is deposited on the bearing surfaces, consequential seizure of the bearings being avoided by making them of frusto-conical form so that the shaft can ride upward to compensate for the deposit. The movable part of each bearing may be longer than the stationary part, to ensure adequate contact between the parts despite a substantial upward movement. The pump may be submersed in the solution as shown in Fig. 3, the bearings then being lubricated by direct contact with the solution.

Abstract: 610,648. Densitometers. HORNER; R. G., and ILFORD, Ltd. April 12, 1946, No. 11313. [Classes 97 (i) and 98 (i)] A densitometer comprises a panel with two light-diffusing apertures behind which are disposed similar light sources, the apertures registering with apertures near the ends of a closed tube, located on the panel and having mirror elements to direct the light passing through the apertures axially along the tube on to diffusely reflecting elements, which form a comparison field to be received through an eye-piece and another aperture in the tube, a movable density wedge being provided between one pair of the registering apertures and having associated therewith a scale and index and means for effecting relative movement thereof to permit of zero adjustments. As shown in Fig. 2, the densitometer comprises a box 10, the upper wall 13 of which is a ground-glass panel, housing a dry battery 14 supplying light bulbs 16, 17 when a switch is closed by downward movement of a plunger 42; the upper end of which, when not in use, rides in a cut-away portion of a ring 32 rotatable about a spindle 39. A scale indicating optical densities is provided on the rim of ring 32 and has cooperating therewith an index mark on a glass plate 33 carried by the ring. The ring also carries a plate 35 fixed as at 36 to the box 10 and a density wedge 34 which alone rotates upon movement of the ring 32. Plates 33, 35 have apertures to allow light from lamp 16 to pass therethrough for reflection at a mirror 24 in a cylindrical passage 22 of a member 20, which is pivoted on a yoke 19 on the box 10. Light from the mirror 24 is diffusely reflected at 26 along another passage 21 and forms one half of the comparison field observed in an eyepiece 23. The other half of this field is formed by light passing from the element 26 to which it has been directed from a mirror 25 receiving light from the lamp 17 through an aperture in a loosely mounted socket 29. The underside of the ground-glass panel 13 is provided with a safolight filter coating except at the small areas thereof immediately about the bulbs 16, 17. In use, member 32 is rotated to close the battery switch and the two parts of the comparison field are made of equal brightness by rotation of wedge 34. The plate 33 is then rotated so that the index thereon coincides with the zero of the scale. The member 20 is pivoted away from the panel and a photographic negative is disposed below the aperture in socket 29. The member 32 is again rotated to give equal brightness of the two parts of the field, the scale reading then giving the density of the negative. Specifications 361,103 and 378,967 are referred to.

Filed: 1950-05-08
Abstract: 688,394. Manure distributers. WHITE, G. J., and KNAPMAN, C. H. April 30, 1951 [May 8, 1950; Feb. 15, 1951], Nos. 11444/50 and 3758/51. Class 6(i) [Also in Group XXX] Relates to manure spreaders of the type described in Specification 595,687, wherein endless screw conveyers 12 feed material to outlets at one end of a wheeled container 8 where it falls on to rotary vaned-discs 96, the screws being mounted in the container so that they continuously engage the upper surface of the material and are lowered automatically as the level sinks. According to this invention, the feed screws are mounted for pivotal movement about an axis A parallel to their axis of rotation. In one form, the screws 12 are mounted on arms 22 pivoted to the end-walls of the container, the drive to the screws being derived from a power take-off on the towing tractor and being transmitted through belts 66 to pulleys 68 coaxial with the axis A and thence transmitted to the feed-screw shafts 14. The feed-screws are of open work construction and are lowered by a winch 28 and cables 24. Rotation of the winch 28 is controlled by a further winch 38 which is connected to the speed-control mechanism 36 described in Specification 641,578, [Group XXIV]. This includes a wheel 42 frictionally rotated by a land-wheel 4 of the machine and connected to the winch 38 through the mechanism 36. The lowering of the feed-screws occurs under gravity but the rate is controlled by the device 36 to prevent the screws from embedding themselves in the material. A handle 40 is used for raising the screws initially. A rotary agitator 84 is mounted above the outlets which are adjustable by sliding doors 104, operable, through cables 108, by a lever 106. The doors have shoots 114 pivoted to their rear edges to direct the discharged material on to the rotary discs 96. The angle of inclination'of the shoots is adjustable so that material may be discharged on to different parts of the discs to vary the extent of spreading. In a modification having a single feed-screw, the levers 22 are mounted on links pivoted to the chassis so that the pivotal axis A is movable.
