Title: Self inflatable life boat equipped with a sailing rig
Inventor: PETRINI LEONIDA
IPC: B63B7/08
Filed: 1982-06-24
Granted: 1985-11-07
Abstract: The self inflated lifeboat is a self contained sailing craft. The boat is compressed air inflated and housed in a metal container (2). This also serves as keel. The container mouth is a hollow metal cylinder. At the base of this, four horizontal arms (4,5) branch out, formed by telescopic rods. On pneumatic expulsion a fifth vertical arm (3), also of telescopic rods, rises from the cylinder. The four arms form jaws to hold the hull (1) along its outside. The cylinder is joined to the boat air chamber by a flexible pipe (8).

Title: Device for aligning a web unwinded from a roll or the like on a guiding or winding element
Inventor: HONEGGER WERNER
IPC: B65H23/02
Filed: 1984-12-14
Granted: 1987-02-19
Abstract: A winding or partitioning strap unwinding from a coil or wound package of printed products as the printed products are unwound is guided through a guide which turns the winding or partitioning strap temporarily through approximately 90 DEG  out of its plane of motion. The winding or partitioning strap is guided in the guide at its flat sides and is aligned with a subsequently arranged deflection roll. The winding or partitioning strap runs from the deflection roll over guide rollers and is subsequently taken up or wound upon a take-up roll or bobbin core. Since the winding or partitioning strap is guided in the guide on the flat sides and not on the edges, an alignment of the winding or partitioning strap unwinding from the coil or wound package in a skew direction with the deflection roll is possible without damaging the strap.

Patent DE-3561714-D1 (DE)
Title: Lifting clamp
Inventor: HOYER PETER DIPL ING
IPC: B66C1/48
Filed: 1985-06-13
Granted: 1988-04-07
Abstract: The hoist clamp has a coupling eye (7) which has a gimbal-type connection by means of the shafts (5,6) to clamp operating crank (14). When a diagonal pull is exerted, the neck (42) of the coupling eye (7) engages against a bracing point (3,4) which is sufficiently high above the shaft (6) to ensure that the lever action provides extra clamping force between the clamps (11,12). When the coupling eye (7) swings about the shaft (5), the coupling eye engages against the upper edges (1,2) of the casing (8), said edges curving outwards, so that additional clamping force is also obtained when the pull exerted is diagonal. Said additional clamping force is only marginally affected by the load (32) held in the load aperture (37).

Granted: 1990-08-23
Abstract: A method and apparatus are described for measuring the velocity, whether rotary or reciprocating, of a servo shaft driven by a motor, without employing a tachometer. From the movement of the shaft is produced a pair of signals in quadrature, with transitions expressible in Gray code for one cycle as 00, 01, 11, 10 and then back to 00. Meanwhile, a clock provides a large number of evenly spaced counts per selected quadrature transitions. The number of counts between two selected quadrature transitions is read and the total number of quadrature transitions between the selected transitions is divided by the total number of counts during the same time.

Abstract: A compaction roller (10) includes improved cleat assemblies (18,19) which employ readily removable wear caps (29, 44). One style of cleat assembly (18) employs means inhibiting twisting of the cap unit about vertical and horizontal axes relative to the support base.

Abstract: A projector lamp comprising a single ended metal halide discharge lamp in a generally spherical reflector has been found to exhibit turbulence when running. The resulting fluctuation of light especially when used in conjunction with the reflector to concentrate the light for studio or theatre applications provides an apparent movement which is extremely disturbing to the eye. It has been found the turbulent movement of gas around the electrodes in the lamp envelope can be regularised by the application of a magnetic field to the envelope. The turbulence is sensitive to conditions within the discharge arc tube and the strength and position of the magnetic field has to be variable to cater for this. The magnetic field is conveniently applied by an electro-magnet using lamp current.
