Patent GB-293851-A (GB)
Abstract: 293,851. Bosch Akt.-Ges., R. July 14, 1927, [Convention date]. Systems, electric; incandescent igniters. - A generator 1 is arranged in circuit with a starting motor 2, switch 3, main accumulator 4 and lamps 5, and also with an auxiliary accumulator 9 used for heating to incandescence the filament igniters 11. Electromagnetic switches 6, 7, or a single combined switch, effect the change-over from battery working when the output of the generator becomes adequate. The armature of the combined switch carries two contacts insulated from each other and connected one to each battery. In the Specification as open to inspection under Sect. 91 (3) (a) an arrangement is described in which the switch 3, Fig. 3 (Cancelled), comprises a press-button switch 22 for the starter 2, and contact-springs 23, 24 which may be caused to engage contacts 18, 19 by turning a cam 26. An incandescent lamp 8 serves as a resistance between the generator and the ignition battery 9. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to a method of magnetically separating ores from gangue and the like
IPC: B03C1/015
Filed: 1954-10-13
Abstract: Finely ground magnetic ore, e.g. Wolframite, Feberite, Columbite, Tantalite, Ilmenite, Cassiterite or Monazite or mixtures thereof, is mixed and agitated with a mineral acid, then washed and dried and subjected to magnetic separation. Hydrochloric, sulphuric and nitric acids of various strengths can be used, hot or cold.  In one method 5 cwt. of minus 100 mesh ore is covered with 30 gallons of water in an acid proof vessel, 40 gallons of concentrated sulphuric acid are pumped in and the mixture is agitated for one hour.  The liquor is drained and the residue is washed, dried and magnetically separated. In a modification the ore water and acid are mixed together, the rise in temperature and reaction providing sufficient agitation without mechanical stirring.

Title: Three point linkages
Inventor: HANKINS MICHAEL EDWARD
IPC: A01B59/041
Filed: 1969-06-13
Abstract: 1,270,702. Tractor power lift mechanisms. M. E. HANKINS and W. P. WALKER. 14 Sept., 1970 [13 June, 1969], No. 30039/69. Heading A1P. A three-point linkage for attaching agricultural implements to track-layers or heavy-duty tractors can be operated hydraulically to move the implement vertically or horizontally. The implement to be attached is connected to the flanges 26 of the arms 10, 10A of the threepoint linkage, to one of which, 10A, is connected one end of a double acting ram 14, the other end being pivoted to the back-plate 11 of the tractor. The ram 14 is operated hydraulically by a lever to swing the arms 10, 10A to the right or left. The lever is mounted on a four-position valve chest 30, the four positions of which are lift, lower, hold, and float, the latter allowing the implement to ride over rough ground, and this valve chest controls the upward movement of the arms 10, 10A. This is effected by means of a lifting ram 20A and a lifting and levelling ram 20, connected at their bottom ends to the arms 10A, 10 respectively by forks 25, and at their top ends to lugs (23) (Fig. 5 not shown) attached to the back-plate 11. A rock shaft 34 extends from ram 20A to ram 20 and serves as a pivotal axis for a pair of rods (42) rigidly mounted on the rock-shaft and carrying microswitches (44, 44A) (Fig. 8, not shown) which are held in contact with the rams 20, 20A respectively. Upward movement of the arm 10A causes the rods (42) to rise and causes the microswitch (44) to break contact with the ram 20, upon which the microswitch (44) operates the solenoid of a control valve 32 to raise the ram 20 until it is level with ram 20A. Similarly downward movement of the ram 20A causes the microswitch (44A) to lose contact, and the control valve 32 is activated to lower the ram 20 until it is level again. The rock shaft 34 is mounted on the tractor back-plate 11 by means of self-centering bearings (40, 40A) to one of which (40A) a device is fitted to tilt the rock shaft and hence the implement. The double-acting ram 14 could be attached to arm 10 near the end attached to the frame, instead of to the frame itself.
