Title: Improvements in or relating to farm tractors having a power operated implement raising mechanism
IPC: A01B63/112
Filed: 1949-06-24
Abstract: 665,504. Agricultural implements. FORD MOTOR CO., Ltd. June 24, 1949. [July 28, 1948] No. 16806/49. Class 6(i). A tractor power mechanism for controlling an implement in accordance with the draft force exerted by the implement is arranged so that it may be used with implements having widely different draft characteristics. As shown a cultivator is attached to draft links 29 which are raised or lowered by a hydraulic piston and cylinder 15, 14. The piston is controlled by a valve 21 operated by a lever 22 connected to a cam member 25 which may be moved by a handle 26. A portion 40 of a rod 37 acts as a fulcrum for the lever 22 and the rod 37 is moved against the action of a compression spring 39 by the reaction of the implement on a link 33 which is connected to a yoke 34 pivoted to the rod 37. The yoke 34 is provided with a plurality of holes 35 for attachment to the link 33 so that by connecting link 33 to the yoke 34 using the upper hole the leverage exerted on the spring 39 may be increased when an implement such as a cultivator exerts a relatively light draft force on the link 33. The link 33 is connected to the yoke 34 using the lower hole when a plough is carried. When the implement draft force compresses the spring 39, the fulcrum point of lever 22 is moved which operates the valve 21 to raise the arms 29 until the lever 22 returns to a point of balance when the valve 21 is closed. Specification 253,556, [Class 89(ii)], is referred to.

Title: Method of producing alkali metal hydrosulphites from formates
IPC: C01B17/66
Filed: 1971-05-25
Abstract: 1309982 Alkali metal hydrosulphites VIRGINIA CHEMICALS Inc 25 May 1971 [16 Nov 1970] 16891/71 Heading C1A  In a process for the production of alkali metal hydrosulphites solutions of (a) SO 2  in a water miscible alcohol and (b) alkali metal hydroxide and formate in water are added to (c) a heated stirred water miscible alcohol containing as an added reactant a formate derived from the alcohol. The preferred temperature range is 60-90 degrees at a preferred press. of 10-50 p.s.i.g. Thus in an example using the apparatus illustrated 1100 p.b.w. of methyl alcohol and 150 p.b.w. methyl formate in reactor 10 were stirred at 83‹ C. and 25 p.s.i.g. A solution of 650 p.b.w. NaOH and 1190 p.b.w. in 880 p.b.w. H 2 O was prepared by heating to 160‹ C. and this solution was added to the reactor via line 16 over 60 minutes. Six minutes after commencement of this addition, addition of a solution of 1920 p.b.w. SO 2  in 2700 p.b.w. CH 3 OH was commenced via line 18 at such a rate that when all the aqueous NaOH/HCO 2 Na soln. had been added 26% of the SO 3 /MCOH solution remained, and this was then added over a further 104 minutes. Throughout these additions the conditions within the reactor were maintained at 83‹C./25 p.s.i.g. and such conditions were maintained for a further 76 minutes before cooling the reactor contents using coils 12 and then the slurry was removed via line 28, the product rinsed with 1200 p.b.w. methanol and dried at 70‹ C. under vacuum to yield 2269 p.b.w. of 92% anhydrous sodium hydrosulphite. During the reaction the pressure was maintained by venting CO 2  evolved and other vapours evolved, e.g. HCO 2 CH 3  were condensed in condensers 22 and 29 and returned to the reactor.

Title: Improvements in or relating to electrical circuits of the kind including an electro-magnetic device
IPC: H01H67/06
Filed: 1955-06-13
Abstract: 785,894. Electric selective signalling systems. GENERAL ELECTRIC CO., Ltd., and SMART, N. C. July 3, 1956 [June 13, 1955], No. 16999/55. Class 40 (1). [Also in Group XXXIX] Means responsive to the receipt of impulses causes each impulse to be applied to a capacitance which is thereby charged, the said means acting at the end of each impulse to connect the capacitance in a closed circuit with the operating winding of an electromagnetic device which is thus operated by the discharge of the capacitance, the arrangement being such that the power supplied to the operating winding upon the termination of an impulse is greater than would have been supplied if the impulse had been applied directly to the operating winding. As shown, Fig. 1, relay A responds to an impulse received at line terminals 1 and 2, connecting condenser 5 to be charged by the impulse. At the end of the impulse, relay A releases and condenser 5 discharges through the winding of the driving magnet 7 of an uniselector 8 which is thereby moved on through one step. With the high-resistance winding of relay A and condenser 5 connected across the line terminals 1 and 2, the potential difference produced between the terminals (and hence across the condenser 5) is greater than if the relatively low-resistance winding of the magnet 7 were so connected, and therefore the initial current through the magnet winding is also correspondingly greater. In the modification shown in Fig. 2, relay B is energized during an impulse train but releases at the end of it so that any subsequent impulse (the switch 13 now being off-normal) does not re-energize relay B and the ensuing discharge of condenser 5 is applied to the release magnet 14, enabling switch 13 to go home.
