Title: Magnetic head
Inventor: DOHMEN GERARDUS MARIA
IPC: G11B17/32
Filed: 1985-09-10
Granted: 1989-04-06
Abstract: A magnetic head according to the invention has a contact face (2) for a flexible magnetic information carrier, which can be moved in a direction (V) along the face (2). A transfer gap (3) merges into the contact face (2). The transfer gap (3) lies in a region (6) of the contact face (2), which is curved into a concave shape in the direction of movement (V). On either side of this region (6) there are located regions (7, 8) curved into a convex shape in the direction of movement (V). The contact face (2) is curved into a convex shape transverse to the direction of movement (V). Due to the shape of the contact face (2), an information carrier exerts only a low pressure on and near the transfer gap (3), as a result of which the degree of wear is low at this area and the life of the magnetic head is long.

Inventor: BLUCHER WILLIAM J
IPC: F16B5/02
Filed: 1985-01-14
Granted: 1989-06-15
Abstract: A fastener for use in attaching an expanded metal lath (30) to a support (28) includes a screw (19) and a spacing element (16). The spacing element (16) is arranged to screw into the lath (30) and abut the support (28). The lath (30) is clamped between the spacing element (16) and a head (12) of the screw (10) and is thereby held away from the support (28) to allow plaster to extrude through openings in the lath (39) and key to the lath (39). The spacing element may be formed integrally with the screw (56 Figure 6) but preferably it is formed as a coil (16) having at least one turn (20) engaging the screw (10) and an outwardly helically spiralling portion (18) which engages the lath (30). The fastener may be driven by a nosepiece (80 Figure 7) which is attachable to a driving tool (90) and has rigid prongs (86) which reach through openings in the lath (30). Travel of a bit of the driving tool (90) is thereby limited so that automatic disengagement occurs to prevent over-driving of the screw and the prongs (86) ensure that the lath (30) is held at a predetermined distance from the support (28).

Abstract: In a known method of friction welding two workpieces together, one workpiece is reciprocated relative to the other while the workpieces are pressed together. When sufficient frictional heat has been generated, relative movement is caused to cease and the workpieces become welded. Apparatus for carrying out that method comprises power-driven reciprocatory means (5;5 min ;10;10 min ;9;12;11) which carries the reciprocating workpiece. To balance the reciprocatory means there are counterweights (20;21;27) which move in the opposite direction to the reciprocatory means. Each counterweight is constrained to guide means (98) to move along a rectilinear path. Each counterweight is coupled to the reciprocatory means by reversing means, which comprises a pivoted rocker (14;15;24), first linking means (16;17;25) and second linking means (18;19;28). Each linking means may be constituted by a flexible blade which is anchored in a non-pivotal manner to the reciprocatory means, the rocker or the counterweight, as the case may be.

Abstract: In the mfr. of aq. colloids by mixing in equal proportions two suspensions resp. contg. amphiphilic and lipophilic components with an aq. buffer soln., a thin moving film formed from the first suspension moves outwards from the raised centre of a rapidly rotated disc to enter as a horizontal layer, into a peripheral channel. Here the layer is contacted and mixed with an injected mixt. of fine droplets of the second suspension. The rates of surface formation in film and mist are approx. equal and the suspensions spread with a film pressure of 5-25 dyn/cm. During this contact, the film speed is reduced by 10-50%, while buffer soln. is added in the same ratio. On the underside of the disc a second peripheral channel is filled with high density viscous liq. to dampen the motion.

Date Oct. 20, 1988.Deposition of a first relatively hard material on a second material that is relatively soft using a rotating rod, bar, tube or other body without translation of the rotating body relative to a workpiece of the second material is achieved by positively cooling the interface between the body and the workpiece such that a shear layer at which heat is being generated moves away from the surface in the direction of the rotating body. On removal of the rotating body from contact with the workpiece, the workpiece is found to be surfaced with material from the rotating body. In a second stage the already deposited material from the rotating body may be cooled by a surrounding body of liquid to enable further material from the rotating body to be deposited on the workpiece. The workpiece may be of plain carbon steel and the rotating body may be of high speed steel or a nickel-based alloy.
