Title: Pulse operated two-axis positioning device
IPC: B23Q1/62
Filed: 1974-08-21
Abstract: 1477741 Linear motors FUJITSU FANUC Ltd 21 Aug 1974 [31 Aug 1973] 36706/74 Heading H2A The two-axis positioning device described in Specification 1,474,408 is modified by arranging the energizing members (toothed polepieces) such that at any time, the force of attraction between the stator and the sliding member is fixed. The energizing members comprise pairs of toothed elements of pitch P (e.g. X A , Xa) arranged symmetrically of the centre point O. Thus since the pairs (X A , Xa) are energized together, the force of attraction always operates at O regardless of which pairs are energized. The Specification states that this reduces vibration and positioning errors.

An electron beam apparatus for treating a workpiece comprises means for focusing an electron beam on the workpiece, means for deflecting the electron beam across the workpiece, a detector for detecting the incidence of the electron beam on a workpiece datum point, having particular characteristics of electron reflection and/or absorption, a computer to which the outputs of the detector is fed and which is pre-set with the co-ordinates representative of a treatment point on the workpiece relative to the datum point, and control means responsive to the computer output to relatively move the workpiece and electron beam so that it impinges on the treatment point. When searching for the datum point the workpiece is scanned under computer control by being divided into several small regions. In order to eliminate spurious signals the datum points comprise pairs of v-shaped notches, the separation distance between which is used as a recognition pattern in a delayed-pulse signal discriminator. Rotational orientation is effected by determining the angle, with respect to co-ordinate areas, of a line between two datum points.

Abstract: 1480168 Forming and bonding metal; superplastic forming ROCKWELL INTERNATIONAL CORP 16 Sept 1975 [3 Oct 1974] 38076/75 Headings B3A B3Q and B3V A method of making a structure from a metal blank having two opposed principal surfaces, and a further workpiece, comprises clamping the blank between two dies with the further workpiece in a cavity in a die, heating the blank and workpiece, inducing tensile stress in the blank and deforming it into intimate contact with the shaping member and further workpiece by a pressure differential between the surfaces, and maintaining the pressure differential and temperature to produce bonding between the blank and further workpiece. In Fig. 2, a lower die 14 receives the further workpiece 29 surrounding a die part or shaping member 22. The blank 24 is placed on the lower die, and surmounted by upper die 32. The assembly is held by the weight of the upper die, or by clamping means, or by ceramic press platens 40, with resistance heaters 42. The workpieces are of titanium or an alloy thereof, so that when a suitable temperature is reached, e.g. 1700 F., and a suitable pressure differential set up between chambers 33, 18, e.g. 60 p.s.i. the blank deforms superplastically into chamber 18, and the temperature is held, and the pressure maintained or increased so that the blank and further workpiece became diffusion bonded over a total time of 3 hours. The pressure differential is established by argon under pressure applied to chamber 33, chamber 18 being vented or evacuated. A titanium ring seal 120 and sealing compound 122, 124 may be used. To prevent bonding of the shaping member 22, it may be made of an iron base alloy of low nickel and 0À2 to 0À5% carbon. Alternatively or additionally, a stop-off coating such as graphite or boron nitrile may be used. The further workpiece may occupy part only of the floor of the lower die, and may be partly or wholly received in a groove therein. The lower die may contain a male die 172, Fig. 9, which may be flanked by further workpieces, or as shown in broken line the further workpieces 158 may initially be held against the blank 24 by shoulders in the die, and will then be superplastically deformed with the blank. Two blank forming arrangements may be employed in mirror image relationship, argon under pressure being introduced between the two blanks 24, to form two structures at once, which may be bonded together between the upper and lower dies to form a hollow enclosure.
