Abstract: The plastic material injection-moulding unit has a supply unit (granules hopper B), arranged on the supply block (10), for feeding the material to be processed via a chute (11) into the plasticising cylinder (15). The supply unit (B) is held by a carrier element (24). The carrier element (24) is displaceable on a guide rail (18) in such a way that the supply unit (B) can be emptied into an emptying channel (23). The guide rail (18) is arranged along the and symmetrically to the vertical plane of symmetry of the injection-moulding unit. Such an arrangement achieves the effect that, with a substantially symmetrical construction, the centre of gravity of the supply unit in the emptying position lies in the vertical plane of symmetry of the injection-moulding unit or is in fact very close to it, it being possible for the transferring of the supply unit (B) into the emptying position to be performed approximately in the plane of symmetry.

Abstract: A hologram recording assembly (10) includes a trans­parent, absorbent member (12) supported on a substrate (14). The transparent member (12) is positioned to be directly incident to an exposure beam (A₁, A₂). The transparent member (12) is out of moisture equilibrium during an exposure time. Consequently, the transparent member (12) increases or decreases in thickness (S) depending on a moisture difference between it and the environment (28). As the thickness (S) changes, a phase shift (A₁°, A₂°) in the light reflections within the recording assembly (10) blurs spurious holograms while leaving the desired hologram intact.

Abstract: A shim set for passively shimming (3,2) and (3,-2) harmonic terms in the field of the magnetic resonance magnet having a cylindrical bore, is provided. Four shims of ferromagnetic material, all of the same size, are secured to the interior of the bore of the magnet. The length of each of the shims is greater than its width. The first two of the shims are secured diametrically opposite one another, near one end of the magnet, with the length of the shims extending circumferentially. One of the first two shims is situated so that a polar angle is created between the axial centerline of the cylindrical bore and an imaginary line extending through the center of the cylindrical bore and the center of the shim, at about 30-44° with 38° being the most desirable location. The second two of the four shims are positioned symmetrically about the axial midplane of the cylindrical bore from the first two of the four shims and rotated 90° circumferentially relative to the first two shims.

Abstract: A connector body (26) which terminates at least one transmission medium includes on each side thereof a cantilevered arm (66) having a latching nub (70) projecting from a free end of the arm. A release cover (80) having a gripping portion (88) oriented toward a cable input end (32) of the connector body is mounted slidably on the connector body with the latching nubs of the arms each projecting through a window (90) in the cover. Conductors in the connector body are connected to conductors of another connector or of a device by inserting the connector body and release cover into a coupling (100) or into a receptacle. The latching nubs of the arms protrude into openings (106-106) provided in a housing (102) of the coupling to secure the connector body thereto. In order to withdraw the connector body from the coupling, a user moves the cover slidably along the connector body toward the cable input end. Walls which define the windows of the cover cam against the latching nubs causing them to be depressed as the free ends of the arms are moved inwardly. Once the nubs have cleared the openings in the coupling or in the receptacle, the connector body and release cover may be withdrawn from the housing. The release cover also is effective when forces of a predetermined magnitude are applied to the connector body to cause the latching nubs to become disengaged from the coupling and allow withdrawal of the connector body therefrom.

Abstract: For more convenient mechanisation, the modulo  m  reduction of a binary number P can be carried out by conditionally summing the modulo m reductions of a power series of two and then modulo m reducing the sum. The modulo m reductions of the series, called the 'residues' of the series, can be pre-calculated and stored but this may be inconvenient if they are long in terms of numbers of bits. Herein, the residues are calculated in sequence by a recursive process, each residue being calculated from the next preceeding one, this leading to a 'serial' arrangement for generating the residues which can be incorporated into a serial modulo m reduction unit. Such a serial modulo m reduction unit is convenient for implementation as an integrated circuit especially as part of an overall circuit for encryption and decryption of digital signals.

Abstract: Packing of a shirred tubular casing section in a tubular net is carried out by, firstly, during shirring with the aid of a stop  which is movable on the shirring tube, leaving an initial section of the tubular casing strand unshirred. After shirring is completed the shirring tube with the stop is withdrawn from the concertinaed tube, and the unshirred tubular casing section is tied off and sealed. Finally, the sealed tubular casing end is pushed into the concertinaed tube and together with this is pushed through a cylindrical carrier, on which a tubular net sealed to form the concertinaed tube is shirred. This net is unfolded by pushing through the concertinaed tube and encloses this along its total length. Finally the tubular net containing the enclosed concertinaed tube is sealed at the other end at two following places and is parted between these. For further processing of the concertinaed tube this only requires to be moistened and to have the end of the net packing torn off, in order to be able to place the concertinaed tube on the filling tube and to begin filling immediately.

Abstract: A positioning controlling device for improving the machineing accuracy of a work of a non-circular shape. A control axis is driven in accordance with an input function consisting of position instruction data corresponding to a machining shape of a work, and a response function of the position of the control axis is measured actually. Then, a transfer function of the servo system is determined from Fourier transformation of the input function and Fourier transformation of the response function, and a corrected input function with which a response function of the control axis ideally corresponds to the machining shape of the work is obtained from the transfer function. Even if the control axis is driven in accordance with the corrected input function, a response function obtained does not correspond to the ideal machining shape of the work. Therefore, the calculations for obtaining an input function described above are sequentially executed until a response function obtained converges to the ideal machining shape. As a result, even if the servo system has a non-linearity, if the control axis is controlled in accordance with an input function finally obtained in this manner, then a response function then corresponds to the ideal machining shape.

Abstract: The heating apparatus comprises metal heating shells (shells 14) each with a single cast-in heating element, which is shaped from a linear pipe to form at least one loop (13). The heating element has supporting faces (13e) which are not covered by the cast metal and on which clearances (14e, 14f) starting from the inner and outer circumferential surface of the shell (14) open out. Such a design achieves the effect that the metal shells can be produced with considerably smaller wall thickness by the pressure diecasting process using relatively high injection pressures. The small wall thickness allows the contact faces (14g) to bear fully against the plasticising cylinder and thus allows more rapid heating (Figs. 7, 7a, 7b).
