Title: Improvements in bale accumulators
Inventor: SAUNDERS PATRICK GEORGE
IPC: A01D85/00
Filed: 1986-03-21
Abstract: A bale accumulator 10 is provided with a bale discharge device 112 at its inlet to receive bales from the discharge end of a baler. The discharge device has a longitudinal passage in which bales moving along the passage are retained until a bale pushes against the rear gate 162 to allow hinged side wall sections, to swing outwardly and drop the bale to the ground in front of the forward diverter gate of the accumulator. The discharge device thus helps to prevent the inlet of the bale accumulator from becoming blocked when a dense amount of material is being baled by bringing a bale into the accumulator over an existing bale. <IMAGE>

Title: Manufacturing crystalline thin films
Inventor: KANOH YASUO
IPC: C30B13/00
Filed: 1986-06-17
Abstract: An energy beam 21 such as a laser beam irradiates a semiconductor layer on a sample 1 to melt the semiconductor layer, and the semiconductor layer is then allowed to recrystallise. Light radiated from the semiconductor layer is detected by a microscope 4 and a television camera 3 and this provides an indication of the melted condition of the semiconductor layer. On the basis of the detected radiated light, the irradiation conditions and other parameters can be controlled so as to produce a high quality recrystallised crystalline thin film. A second energy beam 22 can be provided to preheat the semiconductor layer on the sample 1. <IMAGE>

Title: Reversed-phase packing material and method
Inventor: REGNIER FREDERICK E
IPC: G01N30/88
Filed: 1987-05-13
Abstract: In making the materials, first a thin layer of an adsorbate comprising reactive amine groups e.g. polyethyleneimine is adsorbed to a support material such as silica, alumina or titania. A portion of the reactive amine groups of said adsorbed coating are then reacted with an amount of a hydrophobic reagent e.g. a diepoxide sufficient to effect crosslinking of said coating. At least one remaining reactive amine group, and preferably all of the reactive amine groups of said crosslinked adsorbed coating, are then reacted, preferably in the presence of a proton scavenger, with an amount of another hydrophobic reagent e.g. an anhydride sufficient to form an amide bond with said reactive amine. Alternatively, the same hydrophobic reagent may be used to simultaneously crosslink the coating whilst neutralising the amine groups.

Patent GB-2222554-A (GB)
Title: Sheet and stencil holder
Inventor: TAYLOR LAWRENCE
IPC: B43L13/20
Filed: 1988-09-12
Abstract: A sheet and stencil holder has a well 2 set into the base 1 so as to accommodate a sheet of card or paper. A frame 3 is fixed to the base by hinges 6 and can be raised or lowered with the aid of protusion 5. The area 4 within the frame 3 is of slightly smaller dimensions than of well 2, thus causing the inside edges of the frame to overlap the edges of the well when in the lowered position. This overlap secures the sheet of card or paper in the well 2. Once frame 3 is lowered its inside area 4 forms a second well into which a stencil, of the same dimensions, can be placed. <IMAGE>

Title: Sealed and pressurised hydraulic power-assisted steering system
Inventor: RAYNER ALAN
IPC: B62D5/06
Filed: 1989-06-07
Abstract: A power assisted vehicle steering system has a steering gear (1) with a hydraulic servo motor (6) controlled by an open-centre valve (9). The complete hydraulic system is sealed from atmosphere and the fluid therein is pressurised by gas (typically air) under pressure to a pressure greater than atmospheric, say 2 - 5 atmospheres. To provide such pressurisation the reservoir tank (13) is sealed and provided with a non-return valve (16) which communicates with a headspace (17) in the tank. A gas pressure source (18) is temporarily attached to the valve (16) to effect pressurisation of the headspace. The tank (13) is provided with a gas pressure indicator (19). In a modification, the hydraulic system is pressurised by inflation of an elastomeric bag in the headspace 17. Pressurising the sealed system reduces cavitation, and therefore noise, in the valve and motor and also reduces vibration due to aerated fluid. Leakage from seals is also reduced and the system remains cleaner than conventional systems. <IMAGE>
