Title: Removal of acid-produced staining from paper sheet
Inventor: MILLS BRIAN WALTER
IPC: B44D7/00
Filed: 1984-06-07
Abstract: Staining of paper sheet caused by acidity in the paper is removed by treating the paper sheet with ozone, with or without other gases, in a chamber until the said staining is eliminated or reduced and then removing the sheet from the chamber and treating it with alkali to raise the pH value of the paper to an alkaline pH. The procedure is useful for removing overall staining such as is caused by over acidity of the paper, and overall or localised spot staining due to micro-organisms that produce spots of high acidity upon their decomposition.

Title: Trailer/launching apparatus
Inventor: FISHER ERNEST ENOS
IPC: B63C3/12
Filed: 1985-03-29
Abstract: A boat trailer 1 has variable buoyancy units 3a, 3b, 3c and 3d so that the buoyancy of the trailer may be raised before the trailer and boat are launched into the water and so that the trailer floats with the boat. The buoyancy of the trailer is then lowered by lowering the buoyancy of units 3a, 3b, 3c, 3d until the trailer sinks leaving the boat floating on the water. The buoyancy units 3a, 3b, 3c, 3d may be connected to any convenient pressure source and, for example may be connected to a compressor driven from a vehicle engine. In an alternative embodiment a standard trailer and boat may be driven onto variable support means located at a launching site and the variable support means operated to lower the boat into the water whilst allowing the trailer to sink in a controlled manner. The trailer/launching apparatus may also be used to retrieve a boat from the water. <IMAGE>

Title: Fuel injection pump
Inventor: PRUNEDA DOMINGO CABARROCAS
IPC: F02M41/14
Filed: 1986-03-06
Abstract: A fuel injection pump of the rotary distributor type has a piston 35 for adjusting the timing of fuel delivery, a valve member 28 adjustable to determine fuel quantity and a low pressure pump which supplies fuel at a pressure varying with speed. Fixed orifices 60, 74 are connected in series between the outlet of the low pressure pump and a variable orifice 53, 76 defined by the member 28, the variable orifice allowing fuel flow to a drain. The piston is subject to the pressure intermediate the fixed orifices. A first valve means 45 is responsive to the pressure drop across the orifice 60 and acts to maintain the pressure drop constant on reaching a predetermined value and a second valve means 46 is responsive to the pressure between the orifices and when this attains a predetermined value it opens a flow path from downstream of the orifice 74 to a drain at 54. <IMAGE>
