[Also in Division B8] A protective metal section having a maximum width equal to the thickness of a ligneous sheet material is affixed to an edge thereof by machining the edge such that it fits closely within the section and with the major surface of the sheet material flush with the adjoining surface of the section, and securing the section on the edge by an adhesive. Preferably the adhesive completely fills the space between the section and the sheet. The section is fitted to the sheet by moving it at right-angles to the rebated edge and in the plane of the sheet and is preferably a friction fit thereon to grip the sheet during curing or setting of the adhesive. The ends of the section are mitred to protect the corners of the sheet. Specified adhesives are adhesives having a basis of an epoxy resin or a phenolic, urea or melamine formaldehyde condensation product. A priming coat of adhesive may be applied to the inside face of the section to insure maximum adhesion. The surface of the section to be coated with adhesive may be sand blasted, shot blasted or chemically cleaned and abraded; preferably the ferriferous section is dipped in a solution consisting of 50% industrial methylated spirits and 50% orthophosphoric acid. The section may be of E-section, Fig. 2 (not shown), U-section, Fig. 4 (not shown), or as shown in Figs. 1 and 3. A composite section, Fig. 5, may be provided to form and protect the corners of boxes. Alternatively, Fig. 6, two sections may be provided at the box comer. The sheet material may be plywood, chipboard or a solid sheet of hardwood or softwood and used to construct load-carrying pallets, collapsible and rigid boxes, for shuttering-panels or as support or footways on scaffolding.

Preferred draw ratios may be derived from mathematical formulµ dependent on the values of liquid temperature, and the intrinsic viscosity and mean birefringence of the filaments.

Title: Optical scanning
IPC: G11B7/12
Filed: 1974-10-17
Abstract: 1475179 Automatic control of beam position PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 Oct 1974 [20 Oct 1973] 45091/74 Heading G3R A device for optically scanning an information track on a rotating information carrier comprises a cathode ray tube producing at least one electron beam which is converted into the scanning light beam, and a position detector which feeds a signal to electron beam deflection means in order to correct deviations of the light beam in a direction substantially perpendicular to the information track. As shown, cathode ray tube 10 produces three electron beams 13, 14, 15 which produce corresponding light spots on a luminescent screen 20 and objective 25 images these spots 7, 8, 9 on to the information carrier 1, which may be a video longplay record. The spot images are then directed via semi-transparent mirror 26 on to respective photo diodes 27, 28, 29. The information on carrier 1 is read by spot 8 and fed via photo diode 28 and de-coder 32 to a T.V. display 33. Spots 7 and 9 are used to control the position of spot 8, any difference in the average outputs of photo diodes 27, 29 as detected by amplifier 30 resulting in a correction signal being applied to plates 18 which deflect all three electron beams. This arrangement effects fine adjustment of spot 8 perpendicularly to the information track, scanning of the track generally being effected by mechanical movement of the parts within broken line 35. To avoid fluctuations in the scanning rate due to eccentricities of the carrier 1, the spots 7, 8, 9 may be moved parallel to the track by supplying a signal to deflection plates 17 from an amplifier 31, which detects variations in a carrier wave frequency coded in the track and detected by photo diode 28. A circuit 34 enables spots 7, 8, 9 to be shifted to another part of the track 1. In an alternative embodiment (not shown) there is only one electron beam and corresponding light spot 8. A small 50 KHz alternating voltage is supplied to deflection plates 18, and the 50 KHz component detected at photo diode 28 provides a measure of the size and direction of any beam deviation perpendicular to the track. An appropriate correction signal is then additionally supplied to plates 18.
