Title: Implement lift hitch assembly
IPC: A01D34/64
Filed: 1973-05-18
Abstract: 1406145 Implement lift hitch assembly F M C CORP 18 May 1973 [4 Dec 1972] 23744/73 Headings A1F and A1P A left and right hand lift hitch assembly 15 for hitching an implement such as a mower 24 to a tractor or other vehicle, co-operates with the left and right hand vehicle lift assembly 19 which includes a pair of lift arms 22a, 22b mounted on a lay shaft 20 pivoted by an hydraulic power unit 23. Each pair of lift arms 22a and 22b supports and retains with snap rings 50 and 52 a lift element consisting of a pin 44 loosely encircled by a resilient plastics or metal sleeve 48. The right and left hand hitch assemblies have links 56 and 58 with slots 68 and (70) Fig 2 (not shown) at their upper ends and are pivotally connected at their lower ends to the implement by cap screws 60 and 64. The front end of the implement is connected to the vehicle by drag links 26. Slots 68 and (70) have segmental circular portions 71 slightly larger than the entry portion 71a which in combination with the resilient sleeve 48 forms a retaining action for the pin 44 with the slots. A spring 72 further prevents dislodgment of the pin 44 from the links 56 and 58 but will allow pivoting of the links by hand to detach the slots for unhitching the implement after the latter has been lowered to the ground. The spring 72 will provide sufficient hitching engagement without the sleeve 48 but the latter is for safety. When out of use the spring 72 holds the links 56 and 58 below the upper surface of the mower. A mower which is wider than the vehicle may be slid into position transversely. When an implement has been positioned below the vehicle the hitch links 56 and 58, drag links 26 and drive shaft 30 can be connected ready for use.

IPC: G01N21/31
Filed: 1965-06-03
Abstract: 1,104,636. Photo-electric absorption investigation. BOEING CO. June 3, 1965 [June 10, 1964], No. 23809/65. Heading G1A. In an infrared absorption determination of the concentration of constituents of the atmosphere a single beam of infrared radiation after passing through the atmosphere is chopped and split by mirrors into several chopped beams each of which is reduced by a filter to a narrow range of wavelengths, each range either containing an absorption band of one or more constituents or acting as a reference range containing no absorption bands. A comparison of the intensity of two filtered beams, one containing the absorption band of the wanted constituent and one not which may or may not be the reference beam, leads to the concentration of the constituent. The filtered beams are received by lead sulphide photo-resistors whose outputs are selectively applied to a logarithmic amplifier and difference potentiometer to give a logarithmic ratio. Determining air polution and the concentration of oxygen and water vapour in the atmosphere is considered.
