Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides an electronic detector arranged in such a way that the electrical conductivity between e.g. a surgeon and a patient can be measured.  The detector is pre-ferably placed in the shoes of the surgeon and is through contact members connected to the surgeon's body and to the base on which the surgeon stands, preferably a floor having a certain electrical conductivity, or a disc for this purpose.  AS an electrically conductive operating table is also electrically connected to the same base the patient will be galvanically connected with said base.  The detector can detect the conduc-tivity between the surgeon and the patient and makes it possible to control possible biological leakage, e.g. germ-containing liquid, through perforations in the operating gloves of the surgeon, at which infections in incisions can be avoided to a great extent.

Abstract: ABSTRACT OF THE DISCLOSURE      A trailer mounted wood cutter and loader for cutting tree length material or logs into pulpwood, saw logs, and the like.  The wood cutter and loader includes a framework supporting a plurality of conveying and feeding chains having outwardly extending concave log engaging latches thereon for receiving a tree length log and moving it transversely to feed the logs under a plurality of overhead saws with the cut lengths of logs free falling unto a loading conveyor.  A spring loaded latch assembly is associated with the saws to catch or engage the tree length material prior to the saws engaging the tree length material.  The chain mounted latches combined with the spring loaded latches and a slight upward incline of the conveying and feeding chains co-operate to prevent kickback of the cut length logs and to prevent binding of the logs in relation to the saws.  The loading conveyor includes a pair of aligned but spaced conveyors which enables short wood or logs to be discharged from the loading conveyor so that only the desired cut length logs will be carried by the loading conveyor to a truck body or other area adapted to receive the cut length logs.

Abstract: ABSTRACT OF THE DISCLOSURE            A method is described for sequential replacement of the lining in a rotating mill according to wear of the lining.  Generally, such a lining consists of adjacent zones parallel to the rota-tional axis of the mill, the height of these zones varying periodically in the peripheral direction of the mill.  Accord-ing to the invention rubber beams of equal width are used, and for the replacement operation completely fresh beams of only one height are employed, this height representing the highest one of only a few preselected categories of beams. Upon removal of worn beams, these are reassorted according to the selected categories and those beams worn-out and unfit for even the lowest category are discarded.  Thus, the reassort-ed beams not rejected can be reused properly positioned so as to maintain a suitable variation of the beam height in the peripheral direction of the mill, and only one height of fresh beams need to be held in stock.  When replacing, the particular beam category may be retained at a certain beam position, or completely fresh beams may be inserted at positions of beams completely discarded, whereby the desired variation of beam height in the peripheral direction is obtained by suitable re-placement or rearrangement of the remaining beams.

Abstract: IMPROVED CONTROL SYSTEM FOR REGULATING LARGE          CAPACITY ROTATING MACHINERY            Abstract:    The control system disclosed herein regulates a centrifugal compressor which has inlet guide vanes adjustable to vary the compressor capacity.  A variable speed motor is connected to drive the compressor, and variation of this motor speed provides another input for regulating the compressor capacity.  A control system (104) achieves optimum energy efficiency, while avoiding surge, by the manner in which the motor speed and the inlet guide (PRV)  vane positions are regulated. To do this, a control signal (on 124) must be derived to indicate the compressor head value.  This signal is achieved by providing two signals, one related to the absolute condenser pressure, and the second related to the absolute evaporator pressure.  The control system operates on these two signals to provide a third signal which is a function of a ratio, in which the numerator is the difference between the condenser and evaporator pressures, and the denominator is the evaporator pressure  .    Alternative measurement and processing techniques are described.  This signal affords a very good indication of the compressor head and thus achieves increased efficiency of system operation, with consequent energy conservation, especially at lighter loads and low heads.

Abstract: ABSTRACT          A hollow tubular shaft, containing optical elements for use in a helical scanning facsimile transceiver, is supported horizontally by air bearings and translated linearly along its major axis through cylindrical reading and writing stations by means of a pneumatic cylinder and piston coaxial with the shaft.  An integral reaction-powered air motor provides shaft rotation, and laser beams perform the reading and writing operations, both of which may take place within the same apparatus or either one of which may be executed at a location remote from that of the other. The reading station contains an optical encoding pattern enabling continuous control of the position of the radiation beams relative to the indicia being read, and an electronic memory facilitates the temporary storage and manipulation of information to be recorded by the writing station.  A fail-safe system prevents damage to the scanning mechanism in the event of interruption of the pneumatic or electrical supplies. The apparatus finds particular utility in the production of printing plates for use in Graphic Arts reproduction processes.

Abstract: ABSTRACT OF THE DISCLOSURE               PROCESS FOR COLORING (PRINTING) OF WEB-LIKE OBJECTS, ESPECIALLY SKI COVERINGS, AS WELL AS SIMILAR OBJECTS            The invention refers to a process of coloring (printing) of web-like objects, especially ski coverings of thermoplastic, such as olefins, especially high and low pressure polyethylene where, the layer is broughtcontinuously as a hot foil, essentially in a state of fusion, in contact with a print carrier, on which there has been deposited a print pattern of a dye which transfers first by sublimation and then diffusion.  A transfer of the dye onto foil occurs in a short time and only essentially along a small areal strip perpendicular to the common direction of conveying of layer and print carrier.  It is preferred that the transfer of dye occurs in the gap between rollers through which the foil and the print carrier are guided.  This allows the obtainment of warpage-free print patterns on relatively thin-walled web-like objects in a continuous process, where it is assured that no warpages occur after cooling or reheating of the printed layer.  Also, migration problems are avoided by means of short-term locally limited penetration under high pressure in the roller gap.
