Abstract: ABSTRACT OF THE DISCLOSURE           For sinking of shafts, a cutting machine is pro-vided having its cutting arm pivotable around a vertical axis and a horizontal axis.  The cutting arm carries cutting heads which are rotatable around a horizontal axis horizontally extending perpendicularly to the axis of the cutting arm.  The shaft is sunk around its circumference in the direction of its axis for which the uppermost lead of a screw surface is initially prepared.  On this uppermost lead of the screw surface the cutting machine is advanced until the cutting heads contact the shaft wall.  Subsequently, a floor cut is made whereupon a further floor cut is made at a lower level.  Starting from a corresponding position of the cutting machine, surfaces are cut free starting from the shaft wall.  This manner of operation is continued thereby repeating  the previous process steps until the whole screw surface is cut free, the cutting machine thereby being moved in backward  direction.  Any area possibly remaining close to the axis of the shaft and being not within the operating range of the cutting arm can subsequently be broken away or be removed by cutting operating in another position of the cutting machine.

Abstract: CONTROL ASSEMBLY FOR PELT FAT REMOVAL APPARATUS                  MELVILLE R. REID               ABSTRACT OF THE DISCLOSURE           Improved apparatus is disclosed for increasing the output of a machine for removing fat from the inside of an animal pelt, such as a mink pelt.  In such machines, pelts are mounted inside out on rotatable elongate mandrils, and a cutting head resembling a router trims the fat from the pelt.          The improvement includes a control assembly attached to the cutting head for pivotal movement thereof to control the depth of cut.  The control assembly has a flexible extension which permits the cutting head to move freely longitudinally along the mandril.  The control assembly also has a toggle joint and a lever operably coupled thereto to reduce the effort of pivoting the cutting head.  The depth of cut is therefore con-trolled with reduced effort using a lever in a fixed location on the machine.  A reciprocating element controls the longitudinal position of the cutting head.  The reciprocating element is operated by foot controlled drive means including a motor driven reversing clutch.  Also, stops disengage the clutch to limit longitudinal movement of the cutting head therebeyond.

Abstract: ABSTRACT OF THE DISCLOSURE    A compact, portable, clinical instrument dedicated to hemoglobin determination employs an L.E.D. light source with a peak output wavelength of about 553 nanometers and a yellow-blocking filter with a long wavelength cut-off not longer than about 565 nanometers. Thus, the relative amount of energy in-cident upon the blood sample in the 540 nm. hemoglobin absorption band is maximized. In addition to the L.E.D., the photodetector and the amplifying, inverting, log conversion, digital conversion, display and power supply regulation circuits are also exclusively solid-state. The display is of the reflective or liquid crystal type, and the power supply regulator is a sophisticated inte-grated circuit containing the equivalent of many discrete components. As a result, current consumption is minimized, and battery life and instrument accuracy are maximized. As an alternative illumination source, and infra-red L.E.D. can be employed, and the instrument is then capable of blood turbidity measurement. In either case, the L.E.D. illumination source is powered by a constant-current regulator, which minimizes errors due to fluctuations in illumination intensity.

Abstract: ABSTRACT           Dense, strong, composite materials are produced from mixtures of silicon and silicon carbide.  The composite materials are characterized by a mixture of finely-divided silicon carbide in a substantially continuous matrix of silicon.  The composite materials contain from about 40 to about 60 percent by volume silicon carbide and from about 60 to about 40 percent by volume silicon.  The composite materials are produced by initially producing a finely-divided silicon carbide starting component and forming the component into a green body of the desired shape.  The green body is subsequently impregnated with molten silicon in the absence of any substantial amount of carbon.  Suitably, a thermo-plastic resin binder may be added to the silicon carbide starting material to aid in forming the green body.  the impregnation step may be carried out by surrounding the green body with finely-divide silicon metal and heating the covered body to a temperature above the melting point of silicon.  The composite materials described have flexural strength of over about 90,000 psi at 1100°C., elastic modulus of about 38 million psi at room temperature, are essentially non-porous and have densities ranging from about 2.6 to about 2.8 g/cc.

Abstract: ABSTRACT OF THE DISCLOSURE A windmill for generating electricity in which each blade of the air-screw is connected to the hub by means of at least two resilient strips which are oppositely inclined both in the plane of rotation of the blade and in a plane extending through the rotational axis of the hub. This arrangement results in automatic pitch increase of the blades with higher increase air-screw rotation due to the increasing centrifugal force exerted on the blades, This regulates air-screw speed and prevents excessive speed, especially at low load. this pitch-varying mechanism can also be applied top automotive cooling fans. In accordance with another characteristic, the windmill proper consisting of the air-screw and the electric generator driven thereby, is attached to the supporting tower by a spring system, whereby any shock imparted to the windmill by wind gust, or sudden changes of direction of the wind, will be absorbed by this resilient mounting, thereby diminishing the stresses imparted to the support tower.
