Abstract: 1,230,125. Turbines; axial flow compressors. LICENTIA PATENT-VERWALTUNGS G. m. b. H. July 11, 1968, [July 14, 1967], No.33163/68. Headings F1C and F1T. [Also in Division F2] A diffuser duct 10, e. g. at the outlet of a steam or gas turbine or compressor having rotor blades 11, has a curved ring 14 mounted adjacent a wall 13 of the duct to define with the wall an accelerating passageway for the boundary layer of the fluid flowing through the duct. The construction tends to prevent detachment of the boundary layer from the adjacent wall and thus improves the efficiency of the diffuser.

Abstract: 1,230,464. Printing machines. ADDRESSOGRAPH MULTIGRAPH CORP. 16 Sept., 1968 [15 Sept., 1967], No. 44003/68. Headings B6C and B6F. In a roller-impression printing machine employing fixed type in the form of a "credit card" and selective type in the form of type wheels, a mask 34 overlies the type and overlaps certain non-indicia bearing areas of the type wheels and "credit card" to control the "interference", i.e. the spacing between the roller platen surface and the type. The thin sheet metal mask 34 has a narrow track edge 36 which traverses the top edge portion of the "credit card" 15, which constitutes a non-indicia pad area outside of the indicia area which contains the raised characters 40. By,positioning one edge of the roller platen 30 to ride on track edge 36, the edge acts as a spacer. If the form set is placed under the track edge 36 and on top of card 15, then the form set causes separation of the roller and the "credit card" to the extent of the form set thickness. If the form set is not placed under the edge 36, a rim 38 incorporated on the platen edge acts as additional spacer means. Type wheels, Fig. 5.-Each wheel 18 is formed with a non-indicia bearing pad 41 adjacent each indicia character. The mask 34 is cut to overlay the series of adjacent pads 41, and together with the form set acts as a spacer means to provide the required interference between the roller platen and the indicia character. In addition, the mask 34 will urge all the pads, and therefore the type, to assume a level position.

A method of parting-off a component 12 from bar stock using a parting-off tool 13 having its front cutting edge 14 inclined to the direction of feed of the tool, comprises machining the bar stock adjacent the component to conical form with the open adjacent the component, and applying a lateral force to the component to shear it off at the apex. This is carried out with apparatus as in Fig. 2, wherein the parting-off tool 13 is fixed to a slide 18 which carries a pusher member 16 A lever 21 connects member 16 to a movable abutment block 24 which is on a fixed block 23. As the parting-off tool moves into the work a pin 31 abuts surface 30 forcing block 24 to the right. When the force on the component is sufficient to shear it off, spring 27 moves block 24 to the left, which forces member 16 to the right relative to the parting-off tool ensuring the cone is sheared quickly and the break off point is comparatively clean.

Abstract: 1,265,017. Semi-conductor devices. MATSUSHITA ELECTRONICS CORP. 11 Aug., 1969 [19 Aug., 1968; 4 Sept., 1968; 4 Oct., 1968], No. 40023/69. Heading H1K. In a Schottky barrier device the semiconductor body is provided with a recess, an insulating layer overhanging the edge of the recess, and a metal layer deposited to cover the recess and the surrounding insulating layer so that it forms a Schottky barrier with the semiconductor within the recess surrounded by a space. The space prevents the formation of an inversion layer due to the insulating layer and thus reduces the reverse leakage current and increases the breakdown voltage. As shown, Fig. 3, an N-type layer 11<SP>1</SP> is epitaxially deposited on a Si substrate 11, an insulating layer 12 of silicon oxide or nitride is formed on the surface and a photoetching technique is used to open a circular window 13 in the insulating layer. A recess 14 is then chemically etched in the layer 11<SP>1</SP> the edge of the insulating layer being undercut. A layer 15b of Mo or W is vacuum deposited or sputtered on to the wafer to form a Schottky barrier in the recess surrounded by an annular space 16. The layer 15b is protected by a layer 15a of Au and an ohmic contact is provided on the lower face of the substrate 11 by depositing a layer 17 of Au 3% Sb covered with a layer 18 of Sn. In a second embodiment, Fig. 5 (not shown), the Schottky barrier forms the emitter junction of a transistor. The base region (22) is a diffused or epitaxial P-type layer on an N-type Si substrate (21) and is provided with two P+-type regions (23) which are contacted by electrode layers (25) deposited simultaneously with the Schottky contact (24) which may be of Mo, W, Au, Pt or Pd. The Schottky barrier may alternatively form the collector junction of the transistor or two such barriers may form both the emitter and collector junctions. In a further embodiment, Fig. 6 (not shown), the Schottky barrier forms the gate junction of an FET. The semi-conductor body comprises a high resistivity epitaxial layer (31) on a lower resistivity substrate (30) and after forming the Schottky barrier source and drain electrodes (39, 40) of Au 3% Sb are provided. The invention may also be applied to ICs.

When the reel is empty the photo-relay stops the press. The strip is fed manually up to a removable gauging stop (47) causing a single stroke of the press, during which the feed cam is disengaged and the blade 9 makes an idle stroke. The strip is fed again manually up to a second removable stop (48) and a second stroke is carried out. The feed cam is then re-engaged and the press operates automatically, the stroke of feed carriage 28 being equal to the width of one lamination and the members 21 alternately engaging in opposite ends of one pair of slots and spanning the bridge 23 between consecutive pairs of slots.

Air under pressure is constantly supplied through a hose 80 into a chamber 34 of a housing 12 so as to urge to the left a piston 66 which is coupled to a sleeve 62 connected to the jaw holder 90. When hydraulic fluid is introduced into the chamber 34 via an inlet 82, it first acts on the rear face of the sleeve 52 so that the jaws 98 are closed on the mandrel and then acts to move the piston 66 and sleeve 62 to the right so as to set the rivet. After setting the rivet, the hydraulic pressure is released and air under pressure is supplied via an inlet 60 to a cylinder 36 of the housing 12 in front of a piston 56 connected to the sleeve 52. The sleeve 52 is thereby moved relative to the sleeve 62 so as to open the jaws 98 before the air pressure behind the piston 66 can return the sleeve 62 and jaw holder 90 to the initial position. A stream of air is supplied through an inlet 112 to provide a rearwardly flowing air current through a tube 104 to enable removal of the broken mandrel through the tube 104..
