Title: Lift truck
IPC: B62B3/06
Filed: 1944-03-15
Abstract: 578,450. Elevating trucks. TRIGGS, W. W. (Yale & Towne Manufacturing Co.). March 15, 1944, No. 4847. [Class 108 (i)] In a lift truck having an elevating platform 10 and a lifting head 15, the lifting device 35 is pivoted directly both to the platform and to the lifting head. As shown in Fig. 1, the lifting truck comprises the elevating platform 10 formed by two horizontal legs 13 joined at the rear by a cross-bar 14 and a front standard 11. The lifting head 15 is provided with a steering head 16 with handle 18 and wheels 19 and is connected to the standard by the lifting device in the form of a ratchet link 35, Fig. 5, pivoted to the lifting head at 36 and to the standard at 37. A dashpot 30 is pivoted at 31 to the lifting head and at 32 to the standard 11. The rear supporting wheels 20 are carried on axles secured to lifting links 21 pivoted to the elevating platform and are movable by rods 23 connected at 27 to a link 25 pivoted to the platform at 24 and to the lifting head 15 at 26 whereby elevation of the standard 11 causes the levers 21 to rotate and raise the rear end of the platform. The standard 11, shown in Fig. 5 in the raised position, is raised relatively to the lifting head 15 by a ratchet device 35, 39, and is held in any position by a ratchet bar 50 which can be released by a treadle 58 turning a holding shaft 55, the treadle being returned to its normal position after release by a spring- operated toggle bar 76 actuated by a lug 82 on the standard on its descent from the raised position. The ratchet is operated by an up-anddown movement of the handle 18 to reciprocate a strut 45 to move a lifting lever 41 about its pivot 42 to permit a pawl 39 to engage one of the pins 38 on the ratchet link 35. The ratchet bar 50 is pivoted to the ratchet link at 51 and is provided with notches 52 adapted to engage a cut-away portion of the shaft 55 pivoted in the lifting head 15. The treadle 58 is U-shaped and is loosely pivoted on the shaft 55, the lost motion being limited by a pin 65, and the arm 62 opposite the treadle arm is shaped to engage a pivoted lever 70 adapted to tilt the pawl 39 out of engagement with the pins 38 when the treadle is depressed. The first action on depressing the treadle is to disengage the pawl 39 and then rotate the shaft 55 to dislodge the ratchet bar 50 away from the shaft. If the bar is not released, the lug 64 on the treadle is carried round to complete the dislodgment. When the treadle is fully depressed it is held in that position by the spring-operated rod 76 which has its pivot on the treadle moved beyond the dead centre until the standard 11 descends when the lug 82 thereon strikes a lug 83 on the treadle to break the toggle joint and return the treadle to its normal position. In a modification the ratchet link is provided with teeth operated by the pawl and the ratchet bar is replaced by a holding pawl adapted to be released by the treadle.

Title: Improvements in sols containing actinide metals
IPC: B01J13/00
Filed: 1963-02-06
Abstract: The invention relates to sols in which the particles, which are preferably 10 to 120 millimicrons in diameter, consist of an intimate mixture of hafnia or zirconia, and an oxide of a quadrivalent actinide metal, e.g. urania.  The hafnia or zirconia and the actinide metal oxide may be in solid solution, and the particles may contain less than 40 mol. per cent hafnia or zirconia.  The sols are prepared by autoclaving at a temperature of at least 100 DEG  C., e.g. 100 DEG to 200 DEG C., preferably 150 DEG C., and under a nonoxidizing atmosphere, e.g. nitrogen, (1) a freshly-prepared sol of hafnia or zirconia or a solution of a salt of zirconium or hafnium with a non-oxidizing acid, with (2) a freshly prepared sol of the actinide metal oxide or a solution of a salt of the actinide metal with a non-oxidizing acid, for a time sufficient to give the required sol, e.g. 2 to 40 hours, preferably about 20 hours. The solutions of both components may be the chloride or oxychloride.  The autoclaved sol may be deionised by passing it over an ion exchange resin, and the particles in the autoclaved sol may be separated and redispersed in deionised water.  Example 1 refers to the dilution of a mixed solution of uranous oxychloride and zirconyl chloride with deionised water. This solution was sealed into a glass pressure vessel under nitrogen and autoclaved for 20 hours at 150 DEG  C. without agitation. The thus obtained sol was deionised and then concentrated and redispersed in a minimum amount of deionised water.

The J shoot comprises an upper part having fixed walls 4, and walls 5, 6 which are reciprocated by shafts 13a, 13b, 14a, 14b rotated by a motor 24 and chain drives 23, 21, 16, which shafts rotate eccentrics 11a, 11b, 12a, 12b and move connecting rods 9a, 9b, 10a, 10b attached to the walls.  The lower part of the J shoot has a curved bottom 42, and a curved top 43 which is pivoted about a spindle 44 by an eccentric 46 and crank 45, the lower part of the shoot having holes 4a which allow the tank liquid to enter the shoot.  Rollers 50 and squeezing rollers 55 remove the fabric from the shoot past fresh water jets 51 into a rinsing chamber 52 where ultrasonic vibrators or agitators 54 swirl the water.  In operation, reciprocation of the funnel 28 by crank 31 and connecting rod 30 folds the sprayed fabric into the uppor portion of the J shoot to rest upon a partition 49 which has been moved into a position 49a.  The walls 5, 6, of the shoot meanwhile are reciprocated to cause the fabric layers to rub against one another. When the shaft of the shoot is full the partition 49 is slid aside to allow the fabric to fall into the lower curved portion of the shoot where it floats in the liquid and is kneaded by pivotal movement of the plate 43.  The fabric then passes to the rollers 50 and the rinsing chamber 52. In a modification, Fig. 4 (not shown), the upper part of the shoot has its sides 5, 6, perforated and enclosed by bellows which are flexed by eccentrics and rods to give alternating sucking and expelling effects ensuring relative movement between the superimposed fabric layers.  In a further modification, Fig. 3 (not shown), the shoot is an integral whole not provided with a pivoted plate 43, but is reciprocated bodily by an A.C. energized solenoid moving a plunger rod attached to the shoot.  Another embodiment has the shoot provided with internal ribs to prevent lateral collapse of the fabric pile, or the movable walls 5, 6, may be formed as gratings whereby the fabric penetrates slightly through the mesh and is prevented from collapse.
