Title: Improvements in the manufacture and production of binding agents for road surfaces
IPC: C10C3/02
Filed: 1934-07-28
Abstract: Binding-agents for road surfaces are obtained by reacting residues from the distillation of mineral coal tar with chlorinated aliphatic compounds of high molecular weight in the presence of a condensing agent of the kind used in the Friedel-Craft reaction.  The reaction may be effected at 50--200 DEG  C. and organic solvents may be present.  The product obtained on removing the catalyst is substantially free from chlorine, and resembles asphalt.  The aliphatic material which is chlorinated and used in the reaction may be brown coal, or resinous or waxy material extracted therefrom, such as crude montan wax, or paraffin wax or residues from the distillation of oils and fatty acids, e.g. stearine pitch.  The coal tar residue used may have been freed from volatile constituents by heating to 200 DEG  C.

Abstract: 1431200 Encoding apparatus AMERICAN MFG CO Inc 9 May 1973 [10 May 1972] 22232/73 Heading H3H An encoder comprises a rotatable wheel 5 one side of which has a number of grooves 6 including shallow portions 6b and deep portions 6a, resilient members 7 having portions 7a which engage the grooves and portions 7b which are conductive, and a conductive member 8 with which the portions 7b make contact when the associated portions 7a engage the shallow groove portions. Depression of a push button 2 against the bias of a spring (15), Fig. 2 (not shown), enables an aperture 14b of a member 16 to engage a projection (4) on the back of the wheel 5. On release of the push button, the edge of the aperture pulls the wheel into the next digit position which is displayed in a window 18. The member 8 is connected to a voltage source 11 and depending on which of the members 7 are cammed into contact with the member 8, a parallel output of four "1" or "0" bits is fed to a circuit 12.

Title: Pneumatic drives

Filed: 1961-06-21
Abstract: 950,013. Pneumatic engines. E. K. WIESNAGROTSKI, [trading as MASCHINENFABRIK MEMMINGEN KOMM. GES. Inc. THEODOR OTTO]. June 21, 1961 [June 21, 1960], No. 22530/61. Heading F1S. A pneumatic drive to a machine having a number of working members the drive being effective to cause sequential movement of the members comprises a pair of piston and cylinder units, the pistons being pneumatically drivable in the cylinders and each piston being operable to move one of the working members a first one of the units providing a control over the supply of air at a pressure appropriate to move the piston of the second unit such that the piston is not subjected to air at the appropriate pressure until such time as the piston of the first unit has made an operative movement in its cylinder starting with all the pistons brought into one end position by the return springs 5, 18 and 19 if the valve 8 is now opened for example as a result of an automatic operation then compressed air, which flows out of the pipeline 7 into the cylinder 1, moves the piston as far as the point at which the piston 2 exposes the aperture 10. The working member which is not illustrated but which is connected to the piston rod 3 will execute a short movement since the piston 2 has now exposed the aperture 10 the compressed air will flow through the pipeline 12 into the cylinder 14 and displace the piston rod 16 towards the right when the piston in the cylinder 14 has reached its right-hand position the piston 2 moves further to the right until the piston 2 exposes the aperture 11. The piston in the cylinder 15 then executes its working stroke. When the piston in the cylinder 15 has reached its right-hand end position the piston 2 will move further and reach its righthand end position. In this extreme position of the piston 2 the valve 8 is changed over by control means in such a manner that the cylinder 1 and the following cylinders 14 and 15 are vented. The valve 8 is preferably constructed in the form of a quick vent valve or is coupled to a quick vent valve. The cylinders 14 and 15 may include additional vent pipelines which are indicated at 21 and 22 and which are likewise provided with suitable valves. As a result of the venting the return springs 5, 18 and 19 can bring all the working pistons back into their initial positions. When this position is reached the valves change over again and the working cycle begins afresh. The cylinders may be fixed or movable. The movements of two working members may be combined together. The position of the aperture in the cylinder wall may be varied. There may be a plurality of apertures which can be connected to the following cylinder or closed selectively. The invention is applicable to packaging machines, moulding machines and machine tools.

Title: Improvements in or relating to anion-exchange resins
IPC: B01J39/18
Filed: 1947-08-14
Abstract: An anion-exchange material is produced by reacting epichlorhydrin with a tertiary amine, such as pyridine or its methyl or ethyl derivatives, and insolubilising the product by heating it alone or with a phenol and an aldehyde or with a phenol-aldehyde intermediate condensation product.  The heating is carried out at 130 DEG  C. or higher temperatures.  When prepared for use or regenerated with alkali metal carbonates the product removes from solution anions of mineral and strong organic acids. After treatment with caustic alkali, the material absorbs dissolved silica, CO2, or other weak acids.  In examples: (1) the product obtained by reacting epichlorhydrin with pyridine containing methyl and ethyl pyridines is heated at 150 DEG  C. whilst covered with tetralin; (2) an epichlorhydrin-pyridine reaction product is mixed with a phenol-aldehyde condensate and the mixture heated to 190 DEG  C.  The product in each case is granulated and treated with sodium carbonate or hydroxide.  Specified also are tertiary amines: triethylamine, dimethylaniline, and quinoline; phenols: hydroquinone, catechol, resorcinol and pyrogallol.  The products may be used in the process of Specification 655,555.

Abstract: 1,065,672. Compacting powdery substances. WEYERHAEUSER CO. June 4, 1964 [June 12, 1963], No. 23168/64. Heading B5A. Prior to granulating by rolling, powdery material such as powdered epoxy resin is compacted into friable cakes by a plunger 14 which is vertically reciprocated between a hopper 21 and a cylinder 25, the cake being formed as the plunger 14 descends by air entrained in the powder escaping through vents 16 and compression taking place between the plunger and a horizontally reciprocable gate 17. To prevent sticking of the plunger and undue egress of the powder therethrough, two vented plates are mounted in tandem and preferably the lower is provided with a filter-like material such as coarse felt. The gate 17 is provided with cams 17a and cam surfaces 18a which co-operate with cam surfaces 17b and adjustable cams 18b respectively so that a resilient surface 18 is brought into sealing contact with the lower end of cylinder 25. In operation, material is fed to hopper 21 via a funnel (24), Fig. 1 (not shown), when the plunger 14, Fig. 2, is in its raised position and after compression the plunger is slightly raised to relieve pressure on gate 17 and thereafter the gate is moved to allow the cake to be discharged through port 32. If necessary, discharge of the cake may be facilitated by a small downwards movement of plunger 14.
