Patent FI-970334-A (FI)
Inventor: MORRISON BRUCE ROBERT
IPC: C23C2/00
Filed: 1997-01-27
Abstract: A hot dip coating pot (2) having a strip inlet passage (3) and electro-magnetic plugging means to prevent leakage of bath liquid from the pot through that passage, wherein: the plugging means comprises two magnetic field generators (7) disposed one on each side of the passage; each generator projects an oscillating magnetic field into the passage from at least two poles of opposite polarity that are adjacent the passage and spaced apart in the through direction of the passage; the said at least two poles of each generator are respectively in substantial alignment with the corresponding poles of the other in the transverse direction of the passage; the magnetic fields projected by the generators have flux patterns which are substantially mirror images with reference to a plane of reflection coinciding with a centre plane of the passage; and both generators operate at a frequency of more than seven kiloHertz. When no strip is present the fields combine and extend transversely of the passage. When a strip is present the fields not only plug the passage but also provide restraining forces to prevent deviation of the strip from its intended pass line.

Abstract: 1475632 Boring earth &c NEW JERSEY ZINC CO 15 Jan 1975 [19 April 1974] 1790/75 Heading E1F A core barrel of the type which can be pumped down a drill string 12 and latched to the drill string when it reaches its operative position adjacent the bit includes an actuating member 78 movable between a first position (Fig. 1A) in which it holds the latch 76 in its latched condition and a second position (Fig. 2) in which it holds the latch 76 in its unlatched position, the actuating member 78 being biased towards its first position and being moved to its second position to free the core barrel by an overshot assembly 154 (Fig. 4) which is pumped down the drill string and engages the core barrel. As described the latch 76 consists of two latch arms 80, 82 pivoted on a pin 84 fixed in housing 74. The actuating member 78 consists of a hollow sleeve 136, valve block 130 and a rod 108 carrying a cam block 124 and a lug 122, the assembly being movable in the housing 74. A spring 120 urges the actuating member 78 into its first position (Fig. 1A) in which the lug 122 engages face's 104 on the latch arms 80, 82 to hold them in their latched condition and in which passages 132 in valve block 130 register with passages 138 in the housing 74 to permit the flow of drilling fluid. Depressing sleeve 136 moves the actuating member 78 to its second position (Fig. 2) in which the cam block 124 holds the latch arms 80, 82 in their unlatched position and in which the flow of drilling fluid through the valve block 130 is stopped. The sleeve 136 is depressed by pumping an overshot assembly 154 down the drill string, a block 170 on the overshot assembly 154 engaging the sleeve 136 as its fingers 164, 166 engage the fishing neck or spear point 152 on the core barrel. The core barrel and overshot assembly can then be retrieved by a wireline (not shown) or by reverse circulation of the drilling fluid.

Abstract: 545,338. Extension couches. BURGESS, A. F. (Simmons Co.). Feb. 11, 1941. No. 1854. [Class 52 (ii)] In an extension couch, a movable section 24 .. 27, Fig. 1 is supported (as shown in Fig. 2) in a substantially concealed position beneath the couch, by means of a pivoted ramp 46 one end of which may be lowered to the floor to permit the movable section to be run down the ramp into the forward position shown in Fig. 1. In withdrawing the movable section, a pivoted supporting leg 55 thereon is rocked manually in a forward direction to release a retaining catch and to allow the ramp 46 together with the movable section to be tilted downwards about a pivot 50 so as to clear the lower edge of the couch, when the movable section is drawn forward and down the ramp. Camlike members 49 on the movable section slide over pins 50 on the ramp to steady the forward movement of the section, and a detachable lazy tong mechanism maintains the movable section in parallel relationship with the couch. The movable section may be raised to the correct level relative to the couch by manual operation of a throw-over linkage connected to cross-legs 29, 30. After reversal of the throw-over linkage to collapse the cross-legs, the movable.section may be pushed back on to the ramp until pins 87 interlock with recesses 88 in the ramp after which the ramp and movable section may be swung upwards as a single unit into the locked and concealed position shown in Fig. 2. The combined ramp and movable section substantially balance about the pivot 48 to facilitate manipulation.

Title: Improvements in or relating to liquid-absorbing inlays for compresses
IPC: A61F13/15
Filed: 1964-01-15
Abstract: An absorbent pad for compresses, sanitary towels and babies' diapers, is made of a fibrous web material, e.g. a web of fibrated wood pulp, which has alternating compressed and non-compressed areas defining grooves in its two opposed major faces (Fig. 1, not shown), and which is closely zig-zag folded along lines parallel with said grooves (Figs. 2 and 3, not shown) so that each web portion between two adjacent folding lines is approximately perpendicular to the two major faces and so as to place compacted areas of the web inside the pad between its two major faces and to place non-compacted areas in the two major faces.  The construction of the pad permits better lateral spreading of liquid within the pad.  The alternating compressed and non-compressed areas of the web may be formed by passing the web through fluted rolls.  The folded web may be held in the closely folded condition by known types of wrapping.

The locking means consists of two pawls 95, 95<SP>1</SP> each held in alignment by a spring with a pivoted link 91, 91<SP>1</SP>. The two pivoted links are constrained by a member 98 to move in unison under the influence of a push-rod 90 when a bellows 83 is expanded by mercury vapour in a capsule 82. Operation of a member 70 pivots the pawl 95<SP>1</SP> relatively to the link 911 so that the member 43 is released while operation of a member 74 pivots both pawls and thus releases members 41, 43 simultaneously. In a simpler arrangement, operation of either member (70, 74, Fig. 1) releases both locking pawls through a lever (88, 89). The locking means is used with the gas flow control device of Specification 1,357,141.

Abstract: 772,465. Stuffing-box substitutes. BOURCIER'DE CARBON, C.M.L.L. Jan. 21,1955 [Jan. 23, 1954], No. 1939/55. Class 122 (5). The piston-rod 3 of a telescopic shockabsorber is packed by a washer 8 of resilient material clamped between two flanges 6, 13 axially located in the shock-absorber casing 1 by circlips 10, 12, the inner flange 6 being provided with a guide sleeve 7 of plastic material such as a superpolyamide or superpolyester, for example, nylon for the piston-rod. The outer flange 13 is of metal and has spot-welded thereto a metal cover 15 enclosing a felt washer 14 and supporting a bellows 17 for protecting the rod from mud and dust. The inner flange 6 and the sleeve 7 may be formed as an integral unit of nylon. To prevent extrusion of the resilient washer along the rod 3 the hole in the washer is of frusto-conical shape with the rim of smaller diameter abutting the sleeve 7. The packing unit is entered in the casing 1 by means of a sleeve 22 (Fig. 6) having a recess 24 in one end in which the casing fits, the inner diameter of the sleeve being the same as that of the casing 1 for most of its length but flaring outwards at its other end as at 28. At least three spring- loaded retractable balls 18 project radially inwards in a common plane from the inner wall of the sleeve, the amount by which the balls project being limited by contracting their housings adjacent the inner wall. To assemble the shock-absorber, after the piston 2 and rod 3 are inserted in the casing 1 and the inner circlip 10 is positioned in its groove 9, the sleeve 22 is placed on the casing and the inner flange 6, washer 8, outer flange 13 and outer circlip 13 are threaded in sequence on the rod until they are stopped by the balls 18. A mandrel 23 is then placed on the packing unit and pressed downwards so that the balls 18 are forced outwards and the packing enters the casing until it is stopped by the circlip 10 and, after being compressed, located by the circlip 12 engaging its groove 11.
