Title: Wrapping stacks of packages in stretch film - by sticking packages on pallet which is raised by power cylinder
Inventor: HINNERS FRANZ
IPC: B65B9/13
Filed: 1990-10-11
Abstract: Sacks filled with bulk material are stacked in layers on a pallet and are then secured to the pallet by a covering of stretch film. The pallet (8) is supported by a telescopic power cylinder (7) which is installed with its axis vertical in a pit (2). The pallet (8) is initially on a level with the surrounding floor and as the height of the stack of sacks increases, the power cylinder is retracted so that the upper surface of the stack is level with the surrounding floor.  When the stack has reached the required height a cover made of stretch film is pushed over the stack from a machine which runs on rails alongside the pit. The cover is held over the stack as the stack is pushed upwards into the cover by the power cylinder (7). USE - Securing stacks of packages to a pallet.

Patent DE-4103974-A1 (DE)
Inventor: BAAS DIETER
IPC: G11B21/10
Filed: 1991-02-09
Abstract: In CD players, which are prior art optical sound-reproduction devices, a beam of light is focussed, using a focussing-control circuit, on the compact disc and guided, using a tracking-control circuit, to stay on the data track on the disc. If the light beam encounters a damaged area on the disc, e.g. a scratch or holes, this can lead to failure of both focussing and tracking control. In order to prevent failure of the focussing-control and tracking-control circuits (also referred to as servo circuits) with a damaged disc, the control signal from each servo circuit is stored for at least the last rotation of the disc. During a period in which signal interference occurs, the final control element (SG) is not supplied with the control signal produced by the control unit, but with the stored signal. The invention may be used in CD players, video disc players, DRAW disc players and magneto-optical devices.

Title: Solar panel arrangement for yacht - has fixed, folding and sliding solar panels to provide auxiliary motive power
Inventor: KRANERT KLAUS DR ING
IPC: B63H21/12
Filed: 1991-11-05
Abstract: The self-sufficient auxiliary power source utilises solar panels disposed in various locations around the yacht.

Alternatively, the solar panels may be located on sliding panels that extend outwards from under a false deck when in use. Power from the solar panels is fed either to a drive motor or to lead-acid batteries located as ballast in the keel of the yacht. The latter may also be charged when under sail by using the flow of water past the propeller to turn the drive motor thus generating electrical power. ADVANTAGE - Utilises existing surfaces/locations to provide a secondary power source for yacht propulsion.
