Filed: 1975-05-07
Abstract: A method for controlling and regulating the working cycles of a machine tool on a workpiece, including the steps of measuring the workpiece during the machining and programming the feed speed of the tool depending on another variable quantity, which foresees generating a signal responsive to the elastic strains suffered, during the machining, by the kinematic chain comprising the workpiece and the tool, as a consequence of the tool thrust. The signal is used for controlling the feed speed. An apparatus for controlling and regulating the working cycles of a machine tool including a measuring device for the measurement of the sizes of the workpiece being machined, a stepping motor, a digital counter, a digital analogue converter and adapter responsive to the position of the tool relative to a reference position, a differential amplifier, a program unit for programming the feed speed of the tool and a control unit for varying the feed speed. The stepping motor, digital counter, digital analogue converter and adapter responsive to the position of the tool and the measuring device are connected to the differential amplifier adapted to provide a signal responsive to the elastic strains suffered, during the machining, by the tool, workpiece and kinematic chain, due to the tool thrust. The output of the differential amplifier is connected to the program unit for varying the feed speed of the tool depending on the elastic strains.

Abstract: To determine thrombin or enzymes which cleave the substrates in the same way as thrombin, the material in which the enzymes are to be determined is brought into contact with a novel substrate of the formula I <IMAGE> In the substrate, R2 is a chromogenic radical which is eliminated by enzymatic hydrolysis in the form of the corresponding amine which differs in its absorption spectrum from the substrate of the formula I so that quantitative determination of the enzyme present in the material is possible because the amount of amine which is formed is proportional to the amount of enzyme which is present. In the substrate, the substituents have the meaning stated in Claim 1, and the optionally substituted 1-amino-2-phenylpropionic acid in the peptide chain must be in the D form so that attack of aminopeptidases on the substrate, which would interfere with the determination, is prevented.

Abstract: A garbage suction system having a number of chutes connected to a common horizontal main transport duct, leading to a collection centre having a suitable air suction means, is provided with specially constructed air inlet valves at selected locations. Each chute is provided with a fork type obstruction at the bottom to loosely suspend the garbage, and the air inlet valves are located in the main transport duct at locations such that at least one chute is between the valve and the suction means. In operation a valve will first sense the suction effect and open the transport duct to the atmosphere, thereby providing a sufficient pressure drop across the garbage loosely suspended in a chute so as to cause the restrained garbage to be sucked away. The valve is provided with an automatic closing means so that the operating sequence may be then repeated.

Abstract: METHOD AND APPARATUS FOR TRACKING OBJECTS Two spaced bodies each including three independently oriented radiating antennas are in communication with each other by such means as an electromagnetic or a sonic field.  A first body receives radiation transmitted from a second body and establishes the pointing angles to the second body with respect to the first body.  Further, the radiation received by the first body can include information defining the second body's pointing angles to the first body.  These pointing angles are sufficient for determining the orientation of the second body relative to the first body.  Analogously, radiation received by the second body can include information defining the first body's pointing angles to the second body for determining the orientation of the first body relative to the second body.  Distance between the two bodies can be determined by phase-locking techniques thus providing the capability of a full sixdegree-of-freedom measurement system.

Abstract: The bi-metal spring is composed of three plates, and located in a special chamber. This chamber is filled with water from the closed system, flowing in through connecting holes. These holes are so positioned and dimensioned that communication between the chamber and the remaining fluid volume is limited, thus maintaining a different temp. in the part volume from the remaining fluid. The bi-metal spring exerts a pressure on the valve spindle so that the valve cone locates against the valve seat, preventing fluid from flowing through. The container limiting the bi-metal space is enclosed by an electrical resistance for heating the fluid in it. (Provisional Basic advised week 85/09)

Abstract: The invention relates to a coupling between a drill bit (7) and a drill shaft (6), which at least in an end position in one rotation direction gives an interlocking free from play between the elements, whereby simultaneously the drill bit (7) can be freely rotated in relation to the drill shaft (6) in opposite rotation direction. The drill bit (7) is at the inside provided with a helical spline (11) in which a parallel helical spline (10) arranged on the drill shaft (6) is engaged. The axial motion of the drill bit (7) is delimited by aid of a joint consisting of a peripheric notch (9) cut into the drill shaft (6) and a pin (8) firmly connected to the drill bit (7). The splines (10, 11) have the same pitch s, which is greater than the sum of the spline widths b'+b'', and this brings about that the drill bit (7) can be freely rotated on the drill shaft (6) between two end positions.

Abstract: Apparatus and method for heat sealing a selected segment of a web of at least two layers of biaxially oriented plastic film. The web layers are pressed together and a selected segment of the pressed web is heated above the bonding temperature of the plastic while adjacent web segments are maintained below that temperature. The surfaces pressing thus the heated web segment has a relatively lower surface friction than the surfaces pressing the adjacent web segment, whereby the layers of the heated segment of the web are physically unrestrained against shrinking during heating and are allowed to shrink back to their pre-oriented molecular configuration while the adjacent segment is restrained against movement. A hermetic bead seal is thus formed between the web layers. A product heat sealed according to the novel method is also disclosed.
