Title: An apparatus for shaping a beaker container
IPC: B65D1/00
Filed: 1970-12-17
Abstract: 1279059 Making hollow-ware; cupping HAMAC-HANSELLA GmbH 17 Dec 1970 [22 Jan 1970] 59994/70 Headings B3A and B3Q Apparatus for cutting out and shaping a flanged oval or cylindrical cup having a lip c, Fig. 5, on the flange b comprises a die 50 surrounded by a drawing ring 45 and by a blanking tool 40, and a punch 14 surrounded by holddowns 15, 16, the hold-down 16 releasing the flange b before this is drawn by the ring 45 to form the lip c. An inwardly-rolled edge is formed on the lip c during the return stroke, by a groove 34 in the hold-down 16. A screw 54 in the tool 40 passes through a clearance hole 55 in the drawing ring into a groove 56 in the die 50, which is carried by the piston 58 of a pneumatic cushion. A lower pneumatic cushion 19, 20 supports the hold-downs 15, 16 on pins 18. As the upper tool assembly is lowered in a press an upper hold-down 41 secures a sheet metal workpiece during blanking. Cupping follows, until the inner hold-down 15 and the die 50 are arrested by a stop 32, Fig. 4. Continued movement of the tool 40 releases the hold-down 16 from the flange b before a shoulder 47 on the tool 40 engages the drawing tool 45 and moves it axially for forming the lip c. The air pressure in the cushions doubles during the operation.

Title: Brake wear indicator
IPC: F16D55/2265
Filed: 1978-07-19
Abstract: A wear indicator (16) which in use is secured within a bore (7) in the carrier member of a pin-sliding caliper disc brake comprises electrical conductors (29) which are normally electrically connected by a ring (27) secured to a sleeve (24). A probe (19) is secured to the caliper pin (5) which slides in bore 7 by a spring ring (20) and is coupled to the sleeve (24) by a lost-motion connection formed by flanges (25, 26). The indicator is secured in the bore (7) when the brake pads are new, and because the ring (20) will grip the pin-bore (23) at any point along its length the initial position of the flanges (25, 26) shown in the drawing is always obtained regardless of manufacturing tolerances in the brake components. After predetermined brake pad wear the pin (5) will have moved along the bore (7) sufficiently to bring the flanges (25, 26) into contact and move the ring (27) away from the conductors (29) to provide a brake pad wear signal. A coaxial cable may replace the two conductors. <IMAGE>

Patent GB-2046908-A (GB)
Title: Line length navigation system
IPC: F16L1/12
Filed: 1979-10-19
Abstract: The invention is a guidance system used in laying undersea pipe or cable from a pipe-laying vessel when radio transmissions are unreliable. The system processes parameters derived from sensors normally aboard a pipe-laying vessel and sensors cooperating with active winches applying tension to the several anchor lines. The vessel's pitch, roll, and heading angles are supplied from gyrocompass and vertical gyroscopic instruments. Anchor line elevation and azimuth angles with respect to deck coordinates are yielded by conventional angle pick offs associated with fairlead devices, as are the line axial tension and the length of anchor line paid out. Initial conditions, including the initial position of the vessel, are easily obtained in the usual manner. From certain of these parameters, the invention derives intermediate anchor line parameters for use in computing fairlead motion. The intermediate data is used to compute compensated fairlead motion data by first computing apparent fairlead motion from anchor line tension changes. This version of fairlead motion contains undesired terms due to apparent fairlead motion caused by anchor line length changes and also due to actual fairlead motion caused by vessel attitude changes. Therefore, second and third computations are made of the contributions of the latter effects. This is done so that apparent fairlead motion due to anchor line length change and actual fairlead motion due to vessel attitude change may be subtracted from the measure of apparent fairlead motion as calculated from anchor line tension change, yielding the desired compensated fairlead motion value free of significant disturbing components. An estimated value of vessel position change is then obtained by a least squares estimation involving these fairlead motion terms. Correction of vessel position then follows by cooperative operation of the winch and thruster assemblies.
