Title: Hydraulic control circuit for self-loading scrapers
IPC: F15B11/17
Filed: 1964-08-04
Abstract: 1,062,280. Earth moving equipment. CATERPILLAR TRACTOR CO. Aug. 4, 1964 [Aug. 1, 1963], No. 31373/64. Heading E1F. [Also in Division F1] A hydraulic control system Fig. 1, (not shown) comprises a valve assembly (12) selectively operable to direct fluid supplied by a pump (21) to motors (91, 61) or to a motor (41), and also operable to direct the output of a pump (37) to the motor (41) or to a sump (22). The valve assembly comprises three spool valves (13, 14, 16) respectively controlling e.g. the bowl positioning motors (61), the bowl ejector motor (91), or the elevator motor (41) of a self-loading scraper. With the spool valves in their central positions the output from the pump (21) is returned to the sump (22) through a line (23), intercommunicating passages (26, 28, 31, 33, 46) and a conduit (36), the output from the pump (37) also passing to the sump (22) through lines (39, 38), a bore (32), the passage (33) and the conduit (36). If valve spool (16) is moved to the right communication between the valve bore (32) and the passageway (33) is blocked and the output from the pump (37) drives the motor (41) and returns to the sump (22) through a conduit (43), passages (52, 46) and the conduit (36). If the valve spool (16) is moved further to the right the output from the pump (21) passes from passage (31) to a passage (51) to thereby act with the output of the pump (37) to increase the speed of the motor (41). Movement of the spool (16) to the left directs fluid from the passage (31) to the conduit (43) whereby the motor is driven by the pump (21) in the reverse direction. To lower the scraper bowl the spool (13) is shifted to the left (L) whereby passages (56, 57) and lines (58, 59) are pressurised from the passage (26) to act on the rod sides of the motors (61). Pressurisation of the line (58) also pressurises a conduit (71) to move a pilot piston (73), Fig. 2 (not shown), arranged to open a spring loaded relief valve (76) whereby fluid in the head ends of the motors (61) passes through line (63), passages (67, 68), (69, 33, 46) to the sump (22). To raise the scraper bowl the spool valve (13) is shifted to the right. Valve spool (14) is moved to the left when the ejector motor is to be operated and directs fluid in passage (28) to the passageway (57) thereby pressurising conduits (58, 92). The motors (61) cannot retract since discharge from the head ends through line (63) is prevented by spool valve (13). Pressurisation of the line (92) retracts the motor (91) and opens a valve (93) to allow fluid to discharge from the head and through a conduit (94), passages (96, 69, 33) and conduit (36). When valve spool (14) is shifted to the right passage (28) is connected to line (94) which thereby returns the motor to its original position. In the construction of Figs. 3 and 4 (not shown) the system is adapted to control a plurality of sequentially operable ejector motors.

Title: Process for the production of titanium dioxide pigments
Inventor: RICHMOND JAMES THOMSON
IPC: C01G23/053
Filed: 1955-11-03
Abstract: Titanium dioxide pigments are obtained by hydrolysing titanium sulphate solution and calcining the precipitated titanium dioxide, the hydrolysis or calcination being carried out in the presence of a nucleating agent or seed respectively, capable of promoting rutile formation, wherein the precipitated titanium dioxide is treated in the presence of water with an ammonium compound of alkaline reaction, preferably NH4OH or (NH4)2CO3, t neutralise substantially all the sulphuric acid and produce a pH in the range 5-8.  The precipitate is then washed to remove (NH4)2SO4 with water substantially free from calcium, magnesium, and silicate ions, preferably distilled water, and finally calcined at a temperature such as to yield a titanium dioxide pigment of good colour and substantially wholly in the rutile form.  The temperature used is preferably not more than 100 DEG C. above the minimum temperature required to obtain 95% rutile formation.  If desired, a water insoluble zinc compound, preferably ZnO, Zn(OH)2 or ZnCO3, may be incorporated with the precipitate after the neutralisation of sulphuric acid and before or after washing to remove ammonium sulphate.  Specification 623,813 is referred to.

Abstract: 208,559. Colleye, A., and Willem, H. A. Dec. 16, 1922, [Convention date]. Stands or supports for vehicles. - Relates to mechanism for turning a four-wheeled motor or other vehicle in a restricted space, comprising a fork pivoted to the frame and carrying an additional wheel normally out of contact with, but adapted to be lowered on to the ground so as to raise the steering wheels. A braking device is provided for the additional wheel when it has been lowered into contact with the ground with its fork in an inclined position so that movement of the vehicle automatically causes the fork to raise the steering wheels. The additional wheel 4, or a pair of wheels arranged side-by-side, is mounted in a fork 6 pivoted on an horizontal pivot 7 in bearings 8 carried by a plate 9 having a vertical pivot 10 extending through the front portion of the vehicle frame 11. The pivot 10 is provided with a hand-wheel or other operating member and ball bearings 25 may be interposed between the plate 9 and frame 11. The wheel 4 when lowered, bv means such as a cable 21. into contact with the ground as shown in dotted lines, engages a shoe 12 pivoted to the plate 9 at 13 and controlled by an adjustable spring 17, the engaging surface 24 of the shoe preferably being serrated.

Abstract: 1,217,647. Alarm timepieces. EASTERN TIME Ltd. June 26, 1969, No.32386/69. Heading G3T. An alarm timepiece includes a hammer 3 pivotally mounted for reciprocal movement to intermittently engage a bell or the like to produce an audible noise, and a trip spring 4 and a pin 1 each movable between a hammer restricting and a hammer releasing position. Lugs 7 on an hour wheel 6 driven by a mainspring are normally out of engagement with openings in an adjustable alarm time setting wheel 5 so that the spring 4 mounted on a front plate 9 has its L-shaped end biased into engagement with a lug 3a of the hammer to prevent the hammer striking the bell. At the pre-set time and with the pin in its upper position as shown, the spring 4 releases the hammer which is reciprocated against the bell by an escapement driven by an alarm gear train. At the end of the alarm period the spring 4 is biased back into engagement with the lug 3a and may intercept the hammer between the hammer and its rest position. Depression of the pin 1 however causes rotation of the hammer so that the inclined face of the lug 3a cams the spring towards the other face of the lug thus enabling the hammer to return to its rest position.
