Title: Improvements in or relating to the colouring of wood
Inventor: LUDERS WALDEMAR
IPC: B27K3/06
Filed: 1962-03-15
Abstract: 1,027,221. Dyeing wood. AARONSON BROS. Ltd. March 6, 1963 [March 15,1962], No. 10033/62. Heading D1B. [Also in Division A1] A method of colouring wood comprises drilling a plurality of networks of intersecting drill holes in the trunk of a living tree each network being formed by a first plurality of drill holes which intersect with a second plurality of drill holes, the drill holes comprising the respective networks being arranged out of vertical alignment with one another, feeding into said networks a colouring liquid and sealing said networks so that the liquid may leave the said networks substantially only through the wood of the tree. The colouring liquid may be an aqueous solution of a dye, e.g. an acid dye, or it is possible to introduce two different liquids into adjacent networks whereupon they react to form the colouring material within the tree, e.g. solutions of ferric chloride and potassium ferrocyanide. Alternatively different colouring liquids may be introduced into different networks. Especially suitable dyes are acid dyes of the azo series. When the tree is topped prior to the drilling, the networks of drill holes may be drilled in the trunk near to the top but this method is preferably carried out at a time of year when the sap is tending to fall. Normally however the drill holes are made towards the foot of the trunk up to a height of 10ft. The present method may be applied to trees of many types, e.g. alder, maple, sycamore, lime, birch, beech and poplar. The coloured wood so produced may be used as logs, boards, or especially veneers or bonded veneers, boards bonded with veneers, all in block form or as veneers cut from such blocks. The preferred arrangement of drill hole networks is shown in Figures 4, 5 and 6 wherein the first network is made up of drill holes 32-43 and the second network is made up of drill holes 22-31 which drill holes are so spaced that, e.g. hole 33 is vertically below the mid point between holes 22 and 23.

Title: Improvements in or relating to rotary engines
IPC: F03C1/34
Filed: 1920-04-13
Abstract: 168,093. Montgrand, L. de. April 13, 1920. Rotary and oscillating cylindrical valves.-A rotary engine of the revolving cylinder and reciprocating piston type is arranged for expansive working. A single admission valve and a single exhaust valve in conjunction with ports in the cylinders covered by the pistons controls the distribution to all the cylinders. Other valves located in the passages connecting the cylinders are rotated through 90‹ when it is desired to reverse the engine. Admission takes place at the cylinders A' only, and exhaust from the cylinders B, B<1> by ports X, as controlled respectively by distributors 2, 9. Fig. 1 shows the engine set for rotation in the direction indicated by the arrow. The inlet port commences to open when the roller 20 actuated by the cylinder A<1> is at the point I and is fully open when the point H is reached, at which the stroke of the piston commences. During the stroke the piston uncovers a port leading to the cylinder A, but the piston in this cylinder does not move until the first piston has completed its stroke on account of the shape of the cam surface. The inlet port may remain open if desired until the point C is reached. The piston in A' then remains stationary over the concentric part CD of the cam, and the working stroke of A takes place. The steam passes similarly in succession to the cylinders B', B and is finally exhausted from these cylinders at the moment when the piston in the cylinder B has just completed its working stroke and that in B' is about to commence its return stroke. The volume initially admitted to the small cylinder A' is thus expanded to the volume of the two larger cylinders. Admission to the cylinder A<1> takes place a second time at the point E, and so on successively. By rotating all the valves, such as 3, controlling the connecting passages between the cylinders, through 90‹ the engine may be reversed. Figs 5 and 6 show the arrangement of the distributing valves 2, 9.

Title: Spark ignition systems
Inventor: GILBERT BRIAN
IPC: F02P3/08
Filed: 1965-03-11
Abstract: 1,109,157. Ignition systems. JOSEPH LUCAS (INDUSTRIES) Ltd. March 3, 1966 [March 11, 1965], No.10330/65. Heading F1B, An ignition system comprises first and second terminals which in use are connected to a D. C. source, a control inductor 17 connected across the terminals in a series circuit including switch means 16 which is turned on and off in timed relationship with the engine so that when the switch means is closed energy is stored in the inductor 17, a control capacitor 21 to which the energy stored in the control inductor is transferred when the switch means opens the control capacitor being charged by the control inductor and then commencing to discharge, astorage inductor in which energy is stored when the switch means is closed and a storage capacitor to which energy stored in the storage inductor is transferred when the switch means opens the means operable by the initial discharge of the control capacitor for turning on a switch, providing a discharge path for the storage capacitor so as to produce a spark while the switch means is still open. As shown the switch 23 is a controlled rectifier. When the storage 17 inductor transfers its energy to the storage capacitor, the storage capacitor first charges and then starts to discharge at which point the voltage across the diode 22 turns the controlled rectifier on. The energy may be transferred from the storage inductor to the storage capacitor by way of a transformer the primary winding of which is constituted by the storage inductor. A second diode may be included between the capacitor and switch means, providing a charging path for the capacitor. The interrupter 15 could be a semi-conductor switch controlled by pulses from a magnetic generator operated by the engine. In a modification the transistor 16 may be replaced by the interrupter itself. The storage inductor may have a core which saturates to limit the energy stored in the inductor. Alternatively or in addition a resistor with a large positive temperature coefficient can be connected in series with the inductor 17. Other modifications are described.
