Title: Sliding-bolt fastening device for hinged side panels and tailboards of utility vehicles
IPC: B62D33/037
Filed: 1976-01-30
Abstract: 1505455 Bolts F HESTERBERG & SOHNE 30 Jan 1976 [1 Feb 1975] 03784/76 Addition to 1420587 Heading E2A A bolt 4 slides in a channel formed in a housing 3. An extension 19 of the bolt is linked by pivot 6 to one arm 5 of a toggle, the other arm 8 being attached by pivot 10 to the housing. Arm 5 forms a handle, pulling or pushing which causes bolt 4 to slide and head 18 to engage or disengage with keeper 20. Spring clip 15 is provided to hold the toggle arm in the closed position (Fig. 5). To provide additional security, a screw 24 carrying either a pin 25 or a cam can be used. Tightening this screw causes the cam- or, as shown, the pin 25-to bear on the clip and prevent the release of handle 5. Instead of connecting arm 5 to an extension 19 integral with the bolt, rods may be provided to link pivot 6 to a pin provided on the bolt (Figs. 3, 4 not shown). Bevels on the bolt head 18 and keeper 20 provided a camming action to assist closing. Others forms of bolt-head such as an eyelet or a claw may be used.

The gear 11 engages gears 16 which engage gears 13 fixed to the cylinders 14, and the cylinder 12 is driven frictionally from the cylinders 14. The shaft 10 is fitted with a sliding gear which can engage either a gear 7 or a gear 6 fixed concentrically to a gear 5, and the gears 5, 7 are mounted in a frame 3 which is angularly adjustable by worm gearing 2 to bring either of the gears 5, 7 into engagement with the gear 11. The gears 16 are mounted in curved slots 22 in a sector-shaped frame 18 and sub-frame 25 which is adapted to act as a gear guard and prevent the catching of obstacles in the bite of the gears 11, 16. The frames 18, 25 are angularly adjustable about the shaft by means of screws 21, and are secured in adjusted position by bolts 20. The gears 16 are secured in the required position by means of washers 26, Fig. 6, held by dowels 33 to the frames 18, 25, and nuts 23<1> are finally screwed on the screwed ends of the spindles 23 on which the gears 16 are freely mounted.

Title: Improvements in the production of nickel-chromium alloys
IPC: C22C19/05
Filed: 1957-02-07
Abstract: Ductile and malleable nickel-chromium alloys are produced by melting Ni and Cr together, deoxidizing and degasifying the melt, e.g. by addition of small quantities of carbon, then adding Al and Si to give a final content of Al 4-6 per cent and Si 1-2 per cent, and if desired Mn in amount up to 1 per cent.  Mg may be added as a deoxidizer before the addition of Al and Si and rare earth metals may be added just before tapping the ladle.  A preferred alloy so produced has the perecentage composition: Cr 15.0-25.0, Al 4.0-6.0, Si 1.0-2.0, C 0.03-0.25, Mn up to 1.0, Ni with unavoidable impurities and residual deoxidizers the balance. Electrical resistance wire is formed by casting the melt into ingots, forming the ingots into wire, annealing the wire at a temperature between 1700 DEG F. and 2000 DEG F. and then submitting it to a temperature between 900 DEG F. and 1200 DEG F. for 1 to 20 hours.
