Abstract: 1281055 Feeding sheets POTLATCH FOREST Inc 22 Oct 1969 [6 Nov 1968] 51771/69 Heading B8R Resilient sheets of material 60, e.g. wood veneers, are conveyed from a supply conveyer (10), Figs. 1 and 2 (not shown), to one or more stacking assemblies 40 by a pair of belts 18 having inwardly facing upright flights frictionally engaging the edges of the sheets 60 which are arched transversely so as to be self-supporting during transport. When a sheet 60 reaches its appropriate stacking assembly a rod 53 is moved by a pneumatic cylinder 57 into the position shown in dashed lines so that the edges of the sheet are moved inwardly and thus freed from the belts 18, whereby the sheet can fall on to a stacking table 61. An apparatus (30), Figs. 1, 2, 5, 6 and 7 (not shown), positioned between the supply conveyer (10) and the belts 18 includes a conveyer belt system which acts on the upper and lower surfaces of each sheet to produce the necessary arched configuration.

Abstract: 1,246,528. Welding by fusion. COMMISSARIAT A L'ENERGIE ATOMIQUE. 23 Oct., 1969 [25 Oct., 1968; 20 June, 1969], No. 51985/69. Heading B3R. [Also in Division H1] In an electron beam welding process the quality of the weld is monitored by recording as a function of time the electron current collected by or reflected from the work. When the collected current is recorded (Fig. 1, not shown) the work must be insulated and may be connected to a recorder directly or through a differentiating circuit. If the weld contains solid occlusions or blisters or voids, the recorded signal will show corresponding peaks or troughs (Fig. 2, not shown), the position of which can be calculated from the known speeds of the welding and of the recorder. When the reflected current is to be recorded, a Faraday cage may be insulatingly mounted from the lens of the welding apparatus to collect the reflected electrons (Fig. 3, not shown). The signal may be amplified before being fed to the recorder and/or differentiating circuit.

Headings G1N and G1S. In a remote control system by which a worktable is returned intermittently to a preset zero position, a motor 2, Fig. 1, driving the table vertically, is connectable through switch 14 either to a pre-selectable voltage supply 17 or a circuit for returning the table to a zero position which is preset by potentiometer 7 and indicated at 8. The position of the table is sensed by a differential transformer 9 whose core 13 moves with the table, its two secondary coils 11, 12 being connected in series opposition with the output from an A. C. energized bridge including the potentiometer 7. In a hardness testing device, the workpiece (24), Figs. 2, 3 (former not shown), is placed on a table (23), mounted on a microscope support (22), whose position is adjusted by adjustment of potentiometer 7, until the microscope (25) is focused on the workpiece. The microscope is then replaced by a testing head 26 which carries a diamond 27 on a spring-loaded member 28. The switch 14 is then moved to connect the motor, driving the table, to supply 17, the switch 16 being closed, whereby the table is driven upwards, compressing spring 30, until pin 32 contacts pin 31 to energize relay 33 and to disconnect motor 2 from the supply. After a certain time, switch 14 is reversed, the table moves down to its original position at which the microscope, replacing the head 26, is focused on the indentation.

Abstract: 1324888 Breaking J O KING Jnr 25 Nov 1970 [4 Dec 1969] 56057/70 Heading B3E [Also in Division G1] An external support for a bearing surface B, Fig. 1 and 2 of a fastener F is formed by circumferentially scoring a groove in a tube T at a distance along the tube equal to the length of the surface B, inserting supports 16 and 34 from opposite ends of the tube so that their ends 17 and 37 abut adjacent the groove, and pivoting the supports about their ends 17, 37 to sever the tube at the groove. When the length of the bearing surface B is known from the dimensions of the fastener, the fastener is inserted in an adjustable recess 21 so that only the surface B and head H are exposed over a surface 14 of a block 10. The support 66 is then adjusted so that the end 17 is aligned with the end of the bearing length B. If the bearing length is not known a pin 34, Fig. 6, is inserted through the hole in the workpieces into which the fastener is to be placed until a surface 31 and a tab 38 bear on opposite sides of the workpieces. After removal of the workpieces, the tab 38 is placed in a groove 24 in the block 10 so that the support 16 can be moved to abut the surface 31 to give the required bearing length. If a tube is to be grooved while supported on support 16 the support 34 is replaced by a pin 119 of a tool 110, Fig. 16. The tube, mounted on the support 16 is pushed over the pin 119 against a spring biased bush 125 so that the ends 17 and 21 abut each other, after which an eccentrically mounted cutter 130 is rotated to score a groove in the tube. Finally the tool 110 is pivoted about end 121 to sever the tube. In another embodiment (Fig. 17) the rotary cutter 130 is replaced by a pair of reciprocating cutters (256).
