摘要:
A method of producing a tool insert which comprises a central metal portion having edge regions of superabrasive material bonded thereto and presenting cutting edges or points for the tool insert is disclosed. A body (50) having major surfaces on each of opposite sides thereof, each having spaced strips (64) of superabrasive material, typically abrasive compact such as PCBN or PCD, for example, separated by a metal region or regions, such as cemented carbide, is provided. Each superabrasive strip of one major surface is arranged in register with a superabrasive strip of the opposite major surface. Alternatively, each superabrasive strip extends from one major surface to the opposite major surface. The body is severed from one major surface to the opposite major surface along at least two sets of planes intersecting at or in the respective superabrasive strips to produce the tool insert.

A method of producing a tool insert having superabrasive cutting points or edges is disclosed. A body (10) of a hard metal having major surfaces (12, 14) on each of opposite sides thereof, such as a cemented carbide disc, is provided. Each major surface of the body has an array of pockets (12) filled with a superabrasive material, typically an abrasive compact such as PCBN or PCD, for example. A pocket of one major surface is arranged to be in register with a pocket of the opposite major surface. The body is severed from one major surface to the opposite major surface along at least two sets of planes intersecting at or in respective superabrasive filled pockets to produce the tool insert. The severing of the body is carried out in such a manner as to expose the superabrasive material to form a cutting tip or edge in the tool insert.
摘要:
An arrangement for pressurizing an inflatable sleeve (2) that can be applied, for instance, to the arm of a patient for measuring the patient's blood pressure, or that can be applied to an infusion bag for forced infusion of said infusion to a patient, wherein the device further includes a sleeve-connected pressure gauge (3), a hand pump (30) which is connected to the sleeve (2) via line (54,2) and which includes an air inlet (31) that has a check valve (32), wherein the device also comprises a manually actuable air release valve (55) for controlled release of gas from the sleeve interior, wherein a box (5) is connected in the line (52,4) between the sleeve (2) and the air release valve (53); wherein the box (5) is connectable to a pressurized gas source (20) by means of a hose (8), wherein the hose (8) connects with the interior of the box (5) via a check valve (7) and a manually controllable valve (6) for the input of gas from the pressure gas source to the sleeve (2) via the box (5).
摘要:
A process for manufacturing a decorative mainly isometric thermosetting laminate (1) comprising an isometric core (2), a primary surface layer (10) and optionally a secondary surface layer (20). 85 parts by weight of preferably organic particles are mixed with 15-85 parts by weight of a thermosetting resin such as phenol-formaldehyde resin, melamine-formaldehyde resin, urea-formaldehyde resin or mixtures thereof under powerful kneading in an extruder sot hat friction heat forms. The thermosetting resin is hereby bonded to or impregnating the particles. The particles possibly bonded to one another are parted whereby an agglomerate of resin and particles is formed. The particle/resin mixture is then dried to a water content of below 10%. The dried particle/resin mixture is then evenly distributed and continuously or discontinuously compressed in one or more steps under heat and pressure so that the resin finally cures, whereby an isometric core (2) is formed. The core (2) is during or after the pressing provided with a primary (10) and optionally a secondary (20) surface layer. The invention also relates to a laminate obtained through the process and use thereof.

Materials and methods for inducing an IgG anti-IgE response in a human. The methods can include administering to a human subject a polypeptide comprising a human CH3 domain of IgE located between an opossum CH2 domain of IgE and an opossum CH4 domain of IgE, wherein the polypeptide is administered at a dose from about 30 μg to about 600 μg.
