Title: Stacked goods wrapped in plastics sheet for forklifting - the sheets comprising one horizontal and one vertical bandage
Inventor: RAGNAR LARS
IPC: B65B11/58
Filed: 1974-10-12
Abstract: A stack of goods is arranged with the bottom layer smaller in plan area than the upper layers and is wrapped in plastics sheet, so that the spaces thus formed in the bottom layer permit the entry of the prongs of a forklift truck. The whole stack is wrapped in two separate plastics sheets, one of which passes around it in a horizontal plane and the other in a vertical plane; the dimensions of the sheets are such that as they are pulled round, their edges are drawn inwards around the stack and pull into the cavity existing in the lowest layer; in this region, the sheets are welded together. The cavities to receive the prongs of the forklift truck may be at two opposite sides of the lowest layer, or inside this layer. The package is moisture-tight. It can be lifted by a forklift truck without the use of a pallet. High stability of the package is obtd. by the mutually crossing and sealed sheets. The sealing of the two sheets together in the spaces penetrated by the arms of the fork ensures high strength in this region, thus enabling the bottom layer to be lifted with safety. The machine used for the packaging operation can handle stacks of goods assembled in other machines.

Title: Speed control of solenoid armature to minimise noise - uses derivative action to introduce damping into second order response
Inventor: THOMA FERDINAND
IPC: H01F7/18
Filed: 1975-05-14
Abstract: Speed regulation of the armature of a relay is used to minimise generated noise during switch-over. The system is particularly suited to internal post systems using pneumatic capsule transport through a tube and where relays are used at branch functions for switch over. Capsules at the inlet to a branch are directed to one of two outlets depending upon the position of a lever. The lever is controlled by the armature of a solenoid, the armature being coupled to the slider of a potentiometer. The potentiometer output is transmitted to an amplifier with an RC characteristic to provide a derivative feedback to control the response of the armature, and the derivative term operates in a known way to introduce effective clamping into a second order response.
