Title: Drying tunnel for skins - overhead fan system is reversed to reverse hot air flow around sides
IPC: F26B15/00
Filed: 1974-10-04
Abstract: A rectangular section drying tunnel particularly for skins has a chamber above the tunnel with a fan in the middle, with ducts extending from each side, directing the flow of air towards a steam heated grid, the air then travelling downwards to enter the side of the tunnel. The flow is periodically reversed, so that hot air travelling down one side is extracted at the other side and fed back towards the middle of the upper chamber, where part of the wet air can be exhausted and replaced by dry air from outside. Another system uses oppositely rotating fans which are reversed periodically. A further system employs swinging flaps to reverse the flow.

Title: Refractory support for single-side welding metal plates - using flexible assembly of glass fibre and cardboard
IPC: B23K9/035
Filed: 1974-11-19
Abstract: The support, pref. used in conjunction with a semi-automatic machine for welding the bottom seam of the joint, consists of an assembly formed by glass fibres and a section of cardboard contg. a groove or channel. This support pref. uses only layers of glass fibre, with no other refractory material and with no flux; it is pref. flexible so that it can easily be applied to the bottom surface of the joint, the cardboard channel forming the lower part of the support. The device is used in joining metal plates, esp. in shipbuilding, using V-seams for butt joints, the support being located underneath the base of the V to stop molten metal falling through the gap when the first pass, i.e. the bottom seam, is made. It is easily adapted to fit flat or curved plate and sheet, giving a defect-free bottom seam.

Title: Agricultural hoe with variable blade spacing - has lever operated parallelogram linkage deformable against chassis member to displace blades
IPC: A01B39/18
Filed: 1976-07-27
Abstract: The hoe comprises blades carried on tines supported by longidutinal beams whose spacing may be varied by means of a lever. Raising or lowering of the lever causes a parallelogram linkage to be deformed against a chassis member. The lever is connected directly to an upper rod and by a link to a lower rod, so that the rods move in opposite directions when the lever is moved. Raising of the lever causes the parallelogram linkage to be broadened, and thus the hoe blades are moved apart. The upper rod is fixed to one end of the parallelogram linkage and is slidable along a fixed shaft, and the lower rod merely slides along the shaft.

IPC: B41F30/04
Filed: 1977-02-10
Abstract: To avoid undesired bulging at the trailing end of the rubber blanket, seen in the direction of rotation of the rubber-covered cylinder of an offset printing machine, at least one of the two tensioning spindles (4) serving for tensioning the rubber blanket and arranged in the gap of the cylinder (1) is connected to a spring element (10). The spring element (10) in the form of a torsion bar is arranged in the tensioning spindle (4) of hollow construction.

Title: Measurement of dynamic potential in electrolytic bath - using interrupted electrical supply to measure electromotive force
IPC: G01R19/00
Filed: 1977-03-08
Abstract: Measurement of the dynamic potential at the electrode surface of an electrochemical bath involves interrupting the current flow through the bath and then directly after this measuring the electromotive force between the electrodes and a probe immersed in the bath. The interruption and reconnection of the circuit through the bath is carried out at a constant frequency, each being for a constant time period. The measurement of the electromotive force is carried out for a fixed period. The repeated information obtd. from the measurement of the electromotive force is used to control the current in the bath. This controls the electro-motive force and consequently the current density within close limits. For measuring the dynamic potential in electrochemical baths so that the polarisation of the electrodes can be determined. Laboratory methods for doing this are known but the method claimed is also applicable on an industrial scale.
