Title: Phenol furfural resin compositions
IPC: C08G8/06
Filed: 1963-12-09
Abstract: Polyphenols comprising hydroxylated aromatic nuclei separated by and including at least 2 aliphatic carbon to carbon chains of at least 10 carbon atoms are condensed with furfural. They may be modified with another phenol, e.g. cresol or resorcinol, or aldehyde, e.g. formaldehyde or acetaldehyde.  The products are stated to cure to elastomeric products, to be soluble in alcohol, and to be compatible with addition polymers and lacquers and aqueous emulsions thereof. They may be used to plasticize and donate thermosetting properties to thermoplastic resins and flexibility to other thermosetting resins. Specified combinations include 2 to 98% of the condensate with olefine, vinyl ester, vinyl halide, styrene and acrylate polymers; phenol- or urea-formaldehyde resins; polyesters; polyurethanes; polyamides; cellulose esters; epoxy, silicone fluorocarbon, furane, terpene and petroleum resins; and various natural and synthetic elastomers.  The condensates and compositions thereof may also include pigments, plasticizers, lubricants, stabilizers, metal soaps and fibrous and particulate fillers such as glass and cellulosic fibres, asbestos, wood flour, carbon black, saw dust, diatomaceous earth, clay, metal oxides and carbonates. Specified application of the products are impregnating woven and non-woven fabrics; laminates; coatings; moulding compositions; adhesives; and bonding agents for friction bodies.  In Example 4 the condensate is incorporated in a polyvinyl acetate emulsion which is cast into a curable flexible transparent film.

Title: Vibratory mechanism
IPC: E02D3/074

Abstract: 1,098,287. Vibratory mechanisms. L. MUELLER. Nov. 16, 1965 [Dec. 12, 1964], No. 48602/65. Heading F2X. In a vibratory mechanism two out-of-balance members 5a<SP>1</SP>, 5b<SP>1</SP> capable of limited relative rotation with respect to a third out-of-balance member 6 are provided on each of a pair of parallel shafts, such as 9<SP>1</SP>, having separate chain drives from a motor 1, the members 5a<SP>1</SP>, 5b<SP>1</SP> being connected by pins 8 with arcuate slots 14 in the sprockets of the chain drives so that their position relative to the member 6 is altered when the drive is reversed. A different vibration characteristic may also be obtained by interchanging the sprockets of each drive. The chain drive 46<SP>1</SP> may be omitted and a disc with an arcuate slot to receive the pin 8 of the member 56<SP>1</SP> be mounted on the shaft 9. To ensure that the disc and sprockets of each shaft are correctly related in size to each other, switches controlling the drive motor are actuated by feelers engaging the periphery of the disc and a cylindrical flange on the sprocket.

Title: Improvements in or relating to diverter switches for tap changers
IPC: H01H33/12
Filed: 1966-10-31
Abstract: 1,098,147. Regulating switches. BROWN, BOVERI & CO. Ltd. Oct. 31, 1966 [Nov. 2, 1965], No. 48690/66. Heading H2B. A diverter switch for on-load tap changing comprises a moving contact assembly 4 having an arm 9 carrying a . main contact moved alternately by means not shown between fixed contacts 10 and 11 connected to taps 2 and 3 of transformer 1 (tap selector not shown for clarity), arms 5 and 6 carrying auxiliary arcing contacts, and an arm 18 coupled via an hydraulic drive to a change-over switching arm 13 for appropriate connection of a transition resistor 17 before arm 5 (or 6) breaks with resiliently mounted contact 7 (or 8). The arm 18 is articulated to two pistons 21 moving in a cylinder 22 which is itself slidable in a fixed cylinder 23 immersed in oil. Upon switching from the position shown the left hand piston 21 first closes port 25 and then moves cylinder 22 to the left, thereby pivoting arm 13 to leave contact 15 and engage contact 16 before arm 5 has left contact 7. When ports 24 leave the end of cylinder 23 the piston 21 can move relative to cylinder 22 allowing the assembly 4 to complete its travel while the slight pressure as oil is forced through the ports 24 ensures that cylinder 22 maintains arm 13 against contact 16, this action being assisted by the suction produced by the right hand piston 21. In a modification (Fig. 2, not shown) the ports 24 are spaced from the end of cylinder 22 and the final movement of piston 21 compresses oil in the end of cylinder 22 to provide a braking force on assembly 4 which is determined by the size and position of ports 24 and of a groove (27) in piston 21.
