Title: Improvements relating to the mechanical stress grading of timber
IPC: G01N33/46
Filed: 1979-09-11
Abstract: A machine for stress grading of timber comprising fixed rollers 2, 4, 6 and 8 through which timber to be tested may pass, and movable rollers 14, 16 mounted on a trolley 22. The trolley 22 is movable in a lateral direction (from left to right in Figure 1) by hydraulic means 26 in order to bias one roller 14, 16 or the other against the timber as it passes through, thus applying a bending force to the timber. Once the timber has passed through, the machine in one direction, it is reversed by sensors positioned near the fixed rollers and run back through the machine, the trolley 22, on this reverse traverse, being moved to apply the other roller 14, 16 to the timber, thus applying a bending force in the opposite direction. Sensors 34 and a load cell associated with the cylinder 26 measure the deflection and load on the timber to produce a modulus of elasticity of the span under test. <IMAGE>

Title: Eddy-current distance measuring apparatus
IPC: G01B7/02
Filed: 1980-07-08
Abstract: A resonant circuit comprising a detection coil (3) in parallel with a capacitor (C0) is connected to the feed-back circuit of a positive feedback amplifier (4). A voltage controlled oscillator (5) applies an AC signal to the amplifier, and a phase comparator (6) controls the oscillation frequency in accordance with any phase difference between the outputs of the amplifier and the oscillator so that the oscillator oscillates at the resonant frequency of the resonant circuit. The positive feedback impedance of the amplifier thus comprises only a real component and the feedback factor is maintained constant irrespective of any variation in the detection coil inherent impedance due to temperature change, etc., thereby automatically compensating for the effect of temperature changes on the distance measuring characteristic. <IMAGE>

Title: Improvements In or Relating to Cable Control Attachments for Electrically Driven Apparatus
IPC: A01D34/82
Filed: 1980-10-09
Abstract: Arrangements are described for the the attachment of a swinging cable control arm 1 to mobile apparatus 7 driven by mains voltage from a remote supply through a trailing cable 13. It envisages a pivot 2 supported on a member 5 attached to the handle structure 6 of the apparatus and an arm 1 pivoted at one end on the pivot so that its free end 16 may be swung between extreme working positions in which it projects beyond opposite sides of the apparatus respectively. The supply cable is attached to the arm so that it is held clear of the apparatus while in use. Alternatively the cable may be passed through a hollow arm, in which event it is preferred to provide in-line cable connectors at either side of the arm to facilitate the installation of the attachment. Where the apparatus is required to work on a vertical surface, for example, at least one other working position for the arm may be provided intermediate the extreme positions. <IMAGE>

Patent GB-2084470-A (GB)
Title: Breathing apparatus
IPC: A62B7/00
Filed: 1981-08-19
Abstract: Breathing apparatus such as is used by mine rescue workers or firemen includes a reservoir 6 having two inlets 5, 12 leading to a respirable gas supply connection 1. The inlet 5 has a flow regulator 4 which provides a minimum supply of gas to support life and the inlet 12 is provided with a NOT unit 9 which opens when the pressure in the reservoir falls below a predetermined lower value. An outlet 19 from the reservoir 6 leads through a demand valve 21 to a face mask connection 22. A warning whistle 18 is connected by lines 7, 14, 16 to the gas supply connection 1 through a YES unit 15 which is controlled in dependence on the pressure in the reservoir 6 and opens when this pressure reaches a predetermined higher value. Thus to supply gas for normal breathing, the NOT unit 9 opens intermittently but if breathing drops to a level such that not all the gas supplied through the regulator 4 is breathed, the pressure in the reservoir 6 rises and the YES unit 15 causes the whistle 18 to be sounded. <IMAGE>

Patent GB-2087055-A (GB)
Title: Collapsible Coverboards
IPC: F27D1/18
Filed: 1981-10-19
Abstract: An insulating board for covering the top of a tundish or other vessel, at the start of continuous casting or other operations involving molten metal, combines the functions of a lid and an insulating powder. The board is bonded by a thermally-degradable binder and so disintegrates upon breakdown of the bond when radiantly heated by the molten metal as the metal fills the tundish. The disintegrated board forms an insulating powder which floats on the surface of the molten metal and preferably sinters to form an insulating crust. The board remains intact long enough to confine any splash which occurs as the tundish or other vessel is filled.

Title: Metal containers and method and apparatus for their manufacture
IPC: B21D51/30
Filed: 1981-12-31
Abstract: A cylindrical metal container has a body and end joined by a triple seam having a generally elongate rectangular cross section, the top (5a) and bottom (5d) parts of the seam having a convex substantially semi-elliptical or semi-circular profile. The outer face of the seam bulges outward adjacent its top (5b), or its top and its bottom, and the middle part (5c) between the top and bottom is formed to define a depression interconnecting the top and bottom and substantially parallel to the axis of the container. Body and end flanges (11, 21) are held in overlapping contact with each other in the centre of the seam, a sealing compound (9) being sealed in a void left between the edge of one flange and the curved portion of the other. The seam is formed by nip-bending the edge of the end flange with the first (entry-side) corner of a forming groove in a nip-bending and press forming roll, seaming together the body and end flanges with the forming groove in a seaming roll, then, upon completion of seaming, press forming the seam thus formed into a desired shape with the forming groove in the nip-bending and press forming roll. A nip-bending recess is provided at the first or entry-side corner of the forming groove in the nip-bending and press forming roll. <IMAGE>

Patent GB-2098448-A (GB)
Title: Animal bedding and animal husbandry
IPC: A01K1/015
Filed: 1982-05-14
Abstract: This invention provides for the bedding of animals, including chickens, on litter consisting of a layer of short strips or pieces of absorbent non-toxic paper. The paper, for example in the form of newspaper sheets, is shredded and the shreds are then cut into short strips or small 'diced' pieces which are used as the bedding material and which have a size distribution such that the pieces congeal and form a surface crust or cake at an early stage of use and subsequently break up to form a readily friable material. The layer may take the form of a 'top dressing' covering an existing bedding material to extend its useful life.
