Filed: 1943-07-17
Abstract: 566,190. Making set-screws. NEWALL, A. P. July 17, 1943, No. 11650. [Class 83 (ii)] In the manufacture of socketed-head setscrews, a head is forged and/or machined on one end of a blank and at least a part of the shank is extruded or swaged to a reduced diameter and provided with a rolled thread, preferably by die rolls. A cylindrical socket is formed in the head which is then extruded or swaged to close the socket around a former of the shape required for the socket, and the head is heat treated in a manner to cause local internal hardening of the lateral walls of the socket.

Abstract: 336,935. Commercial Alcohol Co., Ltd., Arthur, J. S., and Gogarten, R. April 20, 1929. Glucose &c.-Decomposition products such as polyoses and monoses are made, from cellulose or cellulose-containing materials by treating the starting material, having a moisture content adjusted by drying or steaming so as not to exceed 50 per cent, with a volatile acid gas such as hydrochloric or hydrofluoric acid gas under cooling to low temperatures, preferably below 0‹ C., and saccharifying the decomposed material without previous removal of the acid by a mixture of steam and acid gas at about 60-75‹ C. The material is partially de-acidified and treated with steam under pressure to convert the sugars to monoses, or boiled with acidified water. Liquefied hydrochloric acid may be used to secure cooling during the treatment of the starting material. An example of the treatment of sawdust is given. Specification 292,919 is referred to.

Title: Improvements relating to control mechanism in tractors for hitched implements
IPC: A01B63/10
Filed: 1958-04-21
Abstract: 886,677. Tractor power lift mechanisms. MASSEY-FERGUSON Inc. April 21, 1958 [May 6, 1957], No. 12499/58. Class 79(1). In a tractor hydraulic power lift system a control valve 82, Fig. 3, operated from draft and position control levers 61, 62 to effect movements of the ram 68 at different speeds according to the valve deflection has means for damping the movement of the valve to prevent actuation of the linkages at excessive speeds. The position control lever 61 actuates the valve 82 through cam 117, cranked follower 121, lost motion linkage 127, 128, lever 113 and plunger 111. Follow-up for returning the valve 82 to neutral is provided from a stud 146 on an arm 74 of the lift arm cross-shaft 76 which moves a spring-loaded link 124 to which the hinge pin 122 of the cranked follower 121 is attached. In the event of rapid movement of the lever 61 the link 124 acts as a safety device to permit delayed response in the follow-up system, the movement of the valve 82 being limited by a stop (not shown) engaged by the lower end of the link 127, and by an adjustable cam stop 176 engaging the top surface of the cranked follower 121. Adjustable damping for limiting the speed of movement of the valve 82 is provided by a plunger 184 coupled to the lever 113 through a push rod 187 to provide a one-way connection and having a needle valve 199 adjustable by a manually actuated cam 207 to control the fluid flow between opposite ends of the plunger 184. The control lever 62 for automatic draft control adjusts the valve 82 through a second cam 152 and cranked follower 156 coupled to the lever 113. Movements resulting from changes in draft loads in the draft links 19 are transmitted to the hinge pin 163 of the cranked follower 156 through a bell crank 169 engaging a stop 171 on a spring-loaded draft responsive frame 22 carrying the draft links. Various lost-motion or one-way connections provide for either the position or the draft control to over-ride the other. The draft responsive frame 22 carrying the draft links 19 is generally "A" shaped and is attached to the underside of the tractor by links 41, Fig. 2, at the rear end while the forward end is slidable longitudinally between plates 34. Longitudinal movement of the frame 22 according to the draft loads is balanced by a spring 53. Rollers 37, 49 mounted on the tractor underside and engaging guide ways 38, 50 in the frame prevent side-ways movements. Alternative attachment points 20 are provided for the top link 18 so that adjustments may be made according to the degree of pitching, soil conditions expected on different implements. Specifications 886,678, 886,679 and 886,680 are referred to.

The stalls support a vacuum line, milk line and wash line and milk receiving vessels 76 for each stall, milk being discharged from the vessels through valve 80 into a common shoot and thence to a collecting vessel located within the working area 5 of the building 1. Chains 63 prevent cows from leaving the stalls the chains being fastened by quick release means. Each stall may be provided with a manger into which rationed feed is delivered and means for washing the teat cups are also provided. A scraper rotating with or independently of the platform is used to push dung into a collecting pit. The common milk collecting vessel may also be located outside the building 1.
