Title: Protection rings for a storage tank wall
Inventor: VATER RICHARD ADAMS
IPC: B65D90/02
Filed: 1981-09-04
Abstract: Large openings in a vertical storage tank wall caused by cracks appearing therein are prevented by surrounding such wall with a plurality of rings 30 which are spaced apart from the wall to be structurally independent of that wall and do not exert a force to the wall until a crack in the wall causes the wall to expand. Such structurally independent rings serve to abut a cracked expanded wall to prevent widening of the crack beyond a size determined by the size of the gap 34. <IMAGE>
Patent GB-2086109-A (GB)
Title: Control system for a dot matrix character printer
IPC: G06K15/10
Filed: 1979-10-10
Abstract: A dot matrix character printer can print characters at variable speeds and with variable pitches (widths), using transition and increment counter means (86) comprising programmable radix counters which control actuation of the printing solenoids based on print head position, with the actuation position being varied with print head velocity, to compensate for the distance travelled by the print head during the time between solenoid actuation and print wire impact; this permits operation at variable printing rates. Printing rate is limited by the cyclic rate of the print head, with an additional limitation based on dot printing density which prevents excessive heating of the printing solenoids. <IMAGE>

The dispensing member (120) may form part of the container; may be inserted as a separate member in the container; or it may be located in the cover (12) for the container. <IMAGE>
Patent GB-2092561-A (GB)
Title: Sintered high density spherical ceramic pellets
IPC: C01F7/025
Filed: 1979-11-22
Abstract: Spherical sintered ceramic pellets, for example of bauxite, have a density in excess of 95% of the maximum theoretical density of the ceramic and repeated random samples of such pellets indicate an average sphericity of greater than 0.82 with 95% confidence limits. In a process for manufacturing spherical sintered ceramic pellets a sinterable ceramic powder composition having an average particle size up to 5 microns is added to a rotatable table mixer provided with a rotatable impacting impeller. The table is rotated at 10-60 rpm and the impeller is rotated with a tip speed of 25-50 meters per second. Sufficient water is added to cause spherical ceramic pellets to form and 5 to 15 per cent of additional ceramic powder is added. The impeller is then rotated with a tip speed of 5-20 meters per second for 1 to 6 minutes while the table is rotated at 10-60 rpm. The pellets are dried at 100-300 DEG C and subsequently furnaced to maximum density. If bauxite is the selected sinterable ceramic powder it will preferably have a maximum average particle size of 4 microns.   The pellets may be used for propping open fractures in a gas or oil well.

Title: Vent-relief valve for a wet motor gerotor fuel pump
Inventor: CARLETON WILLIAM A
IPC: F02M37/20
Filed: 1984-10-26
Abstract: A fuel pump vent-relief valve for venting a vapor pressure less than a working pressure and relieving the fluid pressure when in excess of a predetermined relief pressure includes a valve body having an inlet passage (300), an outlet passage (296), and a valve bore (294) containing a ball valve (292) and a tubular valve (302), the tubular valve and the valve body cooperating to define a relief passage between the inlet passage and the outlet passage. A first spring (306) between the ball valve and the tubular valve biases the ball valve towards the inlet passage and the tubular valve towards the outlet passage, the ball valve being adapted to cooperate with the inlet passage to establish a vapor bypass passage therebetween when the ball valve contacts the inlet passage, the tubular valve having a vent passage (314) therethrough adapted to be closed by the ball valve. A second spring (310) between the tubular valve and the outlet passage biasses the tubular valve towards the inlet passage, to normally close the relief passage. Thus, vapor pressure is vented through the bypass passage and the vent passage until the fluid pressure overcomes the first spring to cause the ball valve to close the vent passage. Subsequently, a rise in fluid pressure above a predetermined relief pressure causes the tubular valve to move towards the outlet passage to open the relief passage. The bias on the ball valve may be provided by gravity. <IMAGE>
