Title: A spheroidal graphite cast iron workpiece cast in sand
Inventor: SCHOCK DR DIETHARD
IPC: C22C37/04
Filed: 1984-10-01
Abstract: To obtain improved plastic deformation properties in spheroidal graphite cast iron workpieces and to avoid precipitation of secondary graphite during martensite hardening and tempering, the workpiece which contains not more than 1% by mass of Si, is free from Al and its structure in the cast state is carbide-free. After heat treatment at least one of the following basic structures is present: ferrite, pearlite, bainite and martensite. These properties are obtained by performing, shortly before solidification - i.e. after the metal leaves the pouring ladle, e.g. in the mould, stream of metal or pouring basin - an inoculation treatment during which 0.1-0.2% by mass of silicon is added to the melt. Solidification is followed by heat treatment to product the aforementioned structure. The iron may contain, in wt.%  vanadium     0-0.5  chromium     0-0.5  manganese    0-1  nickel       0-10  copper       0-3 molybdenum   0-1 %

Title: Grass cutter
Inventor: RAYMOND RICHARD O
IPC: A01D34/64
Filed: 1986-12-05
Abstract: A two wheeled mowing and trimming apparatus is disclosed. A rotating cutting head, positioned out in front of the wheels, can be positioned adjacent to either of the wheels while at the same time being tilted. Control of the cutting head's position is maintained through the use of a handle which allows the operator to tilt the frame. In response to the tilting of the frame the wheels are turned and the apparatus can then be positioned to travel in a direction parallel with a fence or building. With the wheels turned, the vegetation existing along the outside edge of the wheel closest to the structure can be trimmed. Also the cutting head is angled downwardly as a result of the tilting of the frame so that the vegetation can be cut close to the ground.

Title: Scanned surface topography measurement using charged particle beam apparatus
Inventor: NIXON WILLIAM CHARLES
IPC: G01B7/28
Filed: 1990-09-14
Abstract: Scanning electron beam microscope apparatus adapted to display two views of a surface for stereoscopic viewing, wherein two series of electrical signals are obtained by scanning the surface with a normal and then tilted beam characterised by a frame store 36 to which the two series of electrical signals are supplied, the frame store including a feedback loop and input and feedback multiplying means 38, 40 and forming a recursive filter, and signal converter means 42 including an R G B look-up table memory means for generating R, G and B signals for display by a colour monitor 44. Alternate tilting of the beam is achieved by adjusting during alternate scans the currents flowing in the gun alignment coils 12 of the SEM so as to shift the beam, and simultaneously introducing an offset in the signals applied to at least one other element in the beam forming and focusing assembly, to counteract the shift introduced by the alignment adjustment, whereby the point of intersection of the beam axes follows the focal plane as focus is altered. The two video signals may be correlated to produce a correlation signal whose value for each point in the surface indicates the apparent shift in position of that Point as between the normal and tilted beam scans, to produce a signal indicative of the surface topography. The correlating signal may be converted to a focusing control signal and may be enhanced by a process of successive approximations. <IMAGE>
