Abstract: A vehicle braking system of the electronically compensated type wherein driver demand signals to inner closed loop pressure systems for the front and rear brakes are adjusted in accordance with load signals obtained from load sensors (42a, 42b) associated with front and rear axles of the vehicle respectively, these load signals themselves being modified to take account of the weight transfer effect from the rear axle to the front axle during braking. Weight transfer is calculated from the expression: 
Weight transfer = Vehicle Decleration x      the deceleration, gross vehicle weight, height of the centre of gravity of the vehicle and the vehicle wheel base being calculated and stored and manipulated electronically to provide dynamic load apportioning between the various inner closed loop pressure systems controlling the front and rear brakes, respectively.

Abstract: A large number of local area networks (52, 58) are each connected to a backbone network (80) through a network interface module (NIM) (82-88). The NIM transmits messages from one local area network to another local area network across the backbone network by enveloping the local area network message inside the data field of a backbone network message. Each of the NIM constructs a table of addresses. The backbone network messages are each addressed to the particular destination NIM. The destination NIM receives the backbone network message and de-envelopes it for transmission over its own local area network.

Abstract: In a hinge for connecting a temple to a hinge piece of spectacles, at least one hinge eye is located on only one of these elements (hinge piece or temple). The hinge pin extending through this eye is constructed in one piece with the other element (temple or hinge piece). For this purpose, either the hinge pin, consisting of plastic, is injection-moulded into the opening of the hinge eye, or the hinge eye, consisting of plastic, is injection-moulded around the hinge pin. In this case, the procedure is preferably such that one of the two elements is firstly produced with the associated hinge eye or hinge pin, and this firstly produced element forms a part of the surface of the cavity of the injection-moulding tool for the other element, so that the other element is cast directly onto the firstly produced element. The high load-carrying capacity of this hinge prevents breakage due to wear, as a result of which service life is increased, on the one hand, and the hinge can have small dimensions, on the other hand.

Abstract: The opposite ends of a printing plate for rotary printing are mutually joined together in order to produce a cylindrical printing plate which is capable of being mounted on to a printing cylinder, for example a printing cylinder where the diameter is capable of being enlarged. The join is made in such a manner that the photosensitive coating of the printing plate is removed at two end edges, that a right-angled bend bent round at the end is constructed at one end of the plate and that the other end, bent through 90 DEG , is set into the U- bend. The join can be made along a generating line of the cylinder or along a line angled to the generating lines of the cylinder. 
<??>The plate can be mounted with the bent edges directed radially inwards or these edges can be inclined to the cylinder radius. The space which is formed between the two adjacent right-angled bends of the end edges of the printing plate is filled with curing material. In this way, a join is produced which forms a continuous smooth surface for the printing plate in the circumferential direction. The filling material can be removed after the printing plate has been used, thus enabling the printing plate to be stored flat. Alternatively, the join of the plate ends can also be made permanent by introducing an adhesive between the right-angled elements in order, thereby, to create a permanent join in the axial direction.

Abstract: A web or structure is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated on a moving conveying screen that is moved parallel to the axes of the lickerins. Segmented baffle plates may be inserted into the mixing zone to control the lateral or cross-sectional composition of a web formed by the fibers accumulated on the screen. A segmented feed may be used to advantageously deliver different fiber materials at different rates to each lickerin. Radially layered composite web structures having circular cross-sections may be formed with the same apparatus by forming the conveying screen into a U-shape and selectively controlling the air flow through the screen.
