Title: Plant or apparatus utilizing a universal straightening-bending machine
Inventor: DEL FABRO MARCELLO
IPC: B21D11/12
Filed: 1989-11-07
Abstract: ABSTRACT       The invention discloses a straightening-bending device or apparatus utilizing a universal straightening-bending machine, preferably associated with wire stock feeding means.  The straightening-bending machine has a pivotable working plane on a hinging horizontal axis, and advancing and straightening means with opposed rolls to straighten and advance in a longitudinal path the stock which lies on the working plane and associated with eventual guiding means.  The cutting means lies on the same working plane for cutting the stock material and bending means for bending the stock material by means of central anvil means and bending nib, rotating around.  The respective working plane pivoting means is conceived to orient the working plane from a first approximately horizontal position (.beta.°= 90°0) to a second positive inclined position (0°<.beta.°<90°) in which the working plane faces frontally and upwards to a third vertical position (.beta.° = 0°) in which the working plane faces frontally and to a fourth negatively inclined position (0°<-.beta.°<90°) in which the working plane faces frontally and downwards.  The respective pivoting axis of the working table is displaced downwards in respect of the longitudinal stock material advancing path when the working plane is oriented in the third vertical position and the fourth negatively inclined position.

Title: Method for packing a tubular casing length gathered into a hollow cylindrical shirring into a tubular net for subsequent processing as sausage casing in an automatic sausage making machine
Inventor: KOLLROSS GUNTER
IPC: B65B9/10
Filed: 1990-03-07
Abstract: A B S T R A C T          The packing of a tubular casing segment which has been shirred together into a hollow cylindrical shirring formation occurs in a tubular net of such configuration that first, with the shirring accomplished with the aid of an abutment which is movable on the shirring tube, a certain initial segment of the tubular casing length is allowed to be left unshirred.  Following termination of the shirring, the shirring tube is withdrawn with the abutment from the tubular shirring formation, and the unshirred tubular casing length segment is narrowed down or swaged and is sealed.  Finally the sealed tubular casing length tip is inserted with force into the shirring and together with the shirring is thrust through a cylindrical carrier, in which a tubular net is recovered which is sealed to the tubular shirring.  This is turned inside out with the thrusting through of the tubular shirring and surrounds this part along its entire length.  Finally the tubular net with the tubular shirring incorporated therein is sealed at the other end at two points one after the other in sequence and is separated between said two points.   With the further processing of the shirred formation this formation need only be irrigated and the opposite end of the packing need only be torn away, in order to be able to place the shirred formation on the stuffing horn and to be able to begin the filling immediately.

Title: Insulation monitoring system of a direct current power supply system
Inventor: SCHUSTER PHILIPPE
IPC: H02H3/17
Filed: 1990-03-27
Abstract: ABSTRACT            INSULATION MONITORING SYSTEM OF A DIRECT CURRENT POWER SUPPLY SYSTEM            Insulation monitoring of a direct current power supply system is achieved by application of an alternating current and the detector is constituted by a current transformer and a Hall-effect current sensor. This Hall-effect sensor controls a direct current generator, which supplies a compensation winding of the current transformer, so as to prevent saturation of the toroid of this current transformer. When a ground fault occurs, the alternating current generator generates a fault current detected by the transformer.     Refer to figure 1.

Abstract: In the method, particles (16) are classified by locating them in a resonance cavity (10) and applying a swept range of microwave radiation to the cavity. The transmitted signals are detected and analysed. The particle is then assigned to a classification in accordance with changes in the dielectric characteristics of the cavity as a result of the presence of the particle. The radiation is polarised and is applied in at least two mutually orthogonal directions. With the particle located at the centre of the cavity, where the E-field is a maximum, and with signals propagating in at least two mutually orthogonal direction, account is taken of dimensional and orientational inaccuracies from particle to particle.   <IMAGE>
