Title: Apparatus for disassembling wooden structures
Inventor: WILTSHIRE CECIL KENNETH
IPC: B23P19/04
Filed: 1988-04-05
Abstract: A pallet disassembly machine has a rigidly supported horizontal laterally expansible beam structure 31 and parallel to it a rigidly supported H-section beam part 37. Two independently freely rotative cutter-edged discs 23a, 23b, are supported at their hubs by bearing means within a block which is attached to two laterally spaced rollers (not shown) respectively running on flanges 75a, 75b, at opposite sides of the beam part 37. The discs 23a, 23b, are yieldably biassed towards one another so as to contact the outer surfaces 35a, 35b, of the beam structure 31. A pallet is, in use, hung on the beam structure 31 from a stringer thereof. Actuation of the structure 31 causes lateral expansion, side walls of the structure bearing outwardly against the pallet platforms. The discs sense and track this expansion and in so doing are automatically aligned with the joint lines between stringer and platforms. Following such alignment, movement of the discs 23a, 23b, along the beam part 37 severs the nails connecting the pallet parts along the joint lines. <IMAGE>

Patent GB-2226016-A (GB)
Title: CO2 Absorber material
Inventor: VAN DER SMISSEN CARL ERNST
IPC: B01J20/04
Filed: 1989-10-13
Abstract: Known absorber materials for CO2 in protective respiratory apparatus do not granulate very easily. The granules have a low cohesion and tend to form dust. Harder granules which no longer permit formation of dust are obtained by addition of an alkaline salt of an oxyacid, preferably sodium hoxamotaphosphate, to the calcium hydroxide paste before granulating. Other salts of oxyacids e.g. orthophosphoric acid, sulphuric acid, permanganic acid, chromic acid and vanadic acid, can also be used. In this way the cohesiveness of the calcium hydroxide granules is increased considerably without the absorbing capacity for CO2 being impaired.

Title: Controlling access to a keyboard-operated computer system
Inventor: DEVANY JOHN ROBERT
IPC: G06F21/32
Filed: 1990-09-13
Abstract: A method of controlling access to a computer system is provided wherein the delays between successive key depressions of a password are measured, S3, and are compared with stored delays, S4, the differences between successive delays are determined, S5, and are compared with stored differences, S6, and a "degree of belief" score in the range -N to +N is assigned on the basis of the two comparisons, S8. If this score is more positive than a predetermined value +M which is indicative that the delays and differences are those of an authorised user whose characteristic delays and differences are stored in the computer system, then access is allowed immediately. If the "degree of belief" score is more negative than a predetermined negative value -M then access is prohibited. If the "degree of belief" score is in the range -M to +M then the process is repeated. <IMAGE>
