Abstract: A tag particularly a brass ear tag for marking animals such as cattle which have passed an official test comprises a strip (1) formed into two limbs (2,3) and a hollow rivet (5) standing up at the free end of one of the limbs (2), the rivet comprising a stock portion (6) and a head portion (8) with a weak portion (7) of reduced wall thickness therebetween, and a receiver hole (17) through the strip near to the free end of the second of said limbs (3), the receiver hole being of sufficient diameter to receive the head portion of the rivet when the tag is being closed, the head portion (8) being deformed radially outwardly to a splayed configuration after passage through the receiver hole (17), and the metal of the strip which defines the receiver hole being a hardened zone (83, 84) which is adapted to interact with the splayed rivet (5) to cause it to break at the weak portion (7) if an attempt is made to force the limbs (2, 3) of the tag apart after it has been closed. The hardening of the zone (83) around the receiver hole (17) has been effected by working the brass. A zone of the strip surrounding the receiver hole (17) is shaped as a raised annular rim (83) adapted to shelter the splayed head (8) of the rivet in the closed configuration of the tag, the raised rim (83) being provided by deforming and thereby hardening the metal of the strip. The rivet (5) may be a separate component from the strip (1) or may be formed from the material of the strip. An insert for a tagging tool is also described.

Abstract: A video display system employs a memory arrangement for the video data which is sequentially accessed for serial read-out of the bit-mapped video information at a high clock rate, and also randomly accessed in parallel by a microcomputer for generating and updating the information to be displayed. Parallel access to the memory by the microcomputer can occur while the serial video data is being clocked out, so microcomputer I/O and video output conflict only a very minimum amount. Dynamic MOS RAMs with a serial register added provide this dual port memory.

Abstract: A digital signal processor has timing means (5, 8) for providing a succession of sample intervals (ut) in which an incoming digital signals may have discrete values (e(o)). A serial delay (40, 52) such as a multi or single bit shift register progressively delays a digital signal giving a delayed signal (e(m)). An arithmetic section (36) has a plurality of elements (41, 54) such as multi or single bit multipliers, or difference squares. Each element operates on non delayed signals (e(o)) and signals (e(m)) from an associated stage of the delay (40, 52). An accumulating store (37) has a plurality of channels (45, 57) each associated with an arithmetic element (41, 54). Collectively the channels (45, 57) provide the required mathematical operation, auto or cross correlation function or structure function calculation. The interval of delay between channels (45, 57) is arranged to increase substantially geometrically e.g. by V2. The overall delay increase may be variable and geometric although increases between adjacent channels (45, 57) may be approximations to a geometric increase. A variable clip level circuit (53) may be incorporated into the input to the serial delay (52). In one configuration the delay intervals may be adjusted to be the same between each channel.

Abstract: A Josephson junction memory employs memory cells each of which includes only one Josephson junction for writing, together with another in the sense line for reading, and which does not require bipolar control currents or an initializing operation different from the normal write operation. 
<??>Each cell comprises a ground plane pattern (105) on which is deposited a left branch line (107) connected to the counter electrode (108) of the Josephson junction and a right branch line (106). A base electrode line (113) is connected to the base electrode (109) of the Josephson junction and to the junction point (114) of the conductor (116). Leads (117) and (118) provide for the flow of bias current through the loop so formed, and x and y control lines (115, 116) are inductively coupled to the Josephson junction. An aperture in the ground plane layer (105) surrounding the region of the Josephson junction ensures that the control lines (115, 116) are coupled directly to the Josephson junction, but that there is no inductive coupling through the ground plane; this enables symmetrical operation to be obtained using only a single Josephson junction for the write gate in each memory cell.

Abstract: Beim druckluftunterstützten Trennen einer Modelleinrichtung mit einem Modell (6, 6') von einer Formeinrichtung mit einem Formkasten (10, 10') lässt sich dadurch auf wirtschaftliche Weise eine Beschädigung der Formkanten durch plötzlich entweichende Druckluft vermeiden, dass ein Ausgangszustand mit gegenseitiger Abdichtung von Modelleinrichtung und Formeinrichtung hergestellt wird und dass diese Abdichtung bei Druckbeaufschlagung der modellseitigen Formstoffoberfläche zumindest so lange aufrechterhalten wird, bis sich das Modell (6, 6') vollständig von der Formstoffoberfläche abgelöst hat und zwischen diesen ein spaltförmiger, nach aussen abgedichteter Zwischenraum entstanden ist, und dass die Druckluftbeaufschlagung dieses Zwischenraums eingestellt wird, bevor die gegenseitige Abdichtung zwischen Formeinrichtung und Modelleinrichtung aufgehoben wird. Hierdurch wird erreicht, dass sich die in den spaltförmigen Zwischenraum eingeleitete Druckluft bis zum Aufheben der Abdichtung bereits weitgehend entspannt hat.

The fixing roll has in contact therewith a porous sheet or tube of poly(ethylene tetrafluoride) resin through which the release agent is applied to the fixing roll. Pores in the areas of the porous sheet ortube of poly(ethylene tetrafluoride) resin which are not needed for passing release agent therethrough during normal copying operations are closed to form closed-and open-pore areas. A width of the open-pore area is smaller than the width of the surface that which the porous sheet or tube contacts the fixing roll. Preferably, the porous sheet or tube has a pore size in a range of 0.1 to 10 microns and a porosity in a range of 50 to 85%.
