Title: Organo-silicon polymers
IPC: C08G59/02
Filed: 1959-02-09
Abstract: An epoxy-organopolysiloxane, in which an oxirane ring is connected to a Si atom through a saturated C atom connecting bridge, may be made by forming a siloxane polymer or copolymer containing Si-bonded alkenyl radicals from the corresponding silane or silanes and then epoxidizing the alkenyl radical or radicals by means of H2O2 or an organic peroxide.  In Example (1) a siloxane copolymer, made by hydrolysing cyclohexenyltrichlorosilane and dimethyldichlorosilane, was dissolved in toluene and epoxidized by adding formic acid and H2O2 thereto; the resulting polymer was separated and purified to yield a 3:4-epoxycyclohexylmethyl siloxane having a R/Si ratio of 1,64; in other examples similar preparations gave (2) a 3:4-epoxycyclohexylethylsiloxane resin; (3, 4) a 3:4-epoxycyclohexylphenylsiloxane-dimethylsiloxane copolymer; (5) a 3:4-epoxycyclohexylphenylsiloxane - phenylmethylsiloxane copolymer; (6) 9:10-epoxyoctadecylphenylsiloxane and also an epoxidized copolymer of the hydrolysate of crotyltrichlorosilane and dimethyldichlorosilane.  Uses: As potting compounds, since they can be polymerized through the epoxy groups by means of cross-linking agents, e.g. primary and secondary amines and acid anhydrides to yield hard infusible polymers; for modifying other resins containing hydroxyl, carboxyl or oxirane groups, e.g. a mixture of equal quantities of a commercial epoxy resin (reaction product of bisphenol A and epichlorohydrin) and the epoxy-siloxane of Example (3) was cured with phthalic anhydride and tetrapropenylsuccinic anhydride; for making laminates, either alone or in conjunction with epoxy resins; for making silicone rubbers filled with C black or other fillers, e.g. the epoxy-siloxane of Example (4) was milled with a silica filler and hexahydrophthalic anhydride, sheeted and cured at 177 DEG C. under pressure, the curing or cross-linking being effected via the epoxy groups.

Title: Improvements in or relating to valve mechanisms
Inventor: MACGREGOR FRANK ALEXANDER
IPC: F16K31/524
Filed: 1954-02-16
Abstract: 783,516. Valves. HUMPHREYS & GLASGOW, Ltd. Feb. 3, 1955 [Feb. 16, 1954], No. 4555/54. Class 135. Valve mechanism for operating a hinged valve comprises a bent lever 13, Fig. 1, connected at one end by a pivot-pin 24 to a valve disc 10 closable on an annular seating 11 and at its other end to a movable pivot-pin 16 carried by links 17 rotatable about a fixed pivot 18 disposed between the pins 24 and 16 such that when the valve is seated all three pins lie in the plane of the valve seating. The lever is formed with first and second arcuate cam surface 25, 27 which coact with a roller 21 fixed to angle brackets 22 mounted on the valve casing, and a spring 23, Fig. 2, connected to the pin 16 and the bracket 22 urges the pin upwardly and the cam surfaces into engagement with the roller so that in the seated position of the valve the spring exerts a closing force on the valve disc. The lever 13 tends to rotate about an instantaneous centre 26 disposed at the intersection of the plane containing the pivots and a plane containing the axis of the roller 21 and the point of contact between the roller and the surface 25. As the valve is opened by downward pull on an operating rod 20 having a pin and slot lost-motion connection 19 with the lever, the surface 27 engages the roller 21 and the instantaneous centre moves to a position between the pin 16 and the rod 20 to provide a turning moment which partly counterbalances the weight of the valve. Upward movement of the pin 16 when the valve is near fully open position is checked by a stop 28 and when fully open the valve closes a circular aperture 14 in a stack casing in which it is fitted to isolate the lever and other working parts from the hot gases in the stack. If the surface 25 of the lever 13 is convex as in Fig. 1 and the valve lifts under internal pressure, the instantaneous centre will move nearer to the spring 23 to reduce the loading on the valve which thus acts as a pressure-relief valve which triggers open at a predetermined pressure. A torsion spring 29 may be provided around the pin 16 to place a turning couple on the links 17 to counterbalance the weight of the valve.

A continuously-variable line, e.g. for use as a variable feed-back path in a tunable R.F. amplifier, comprises a flexible conductor 3 which may be wound off a conductive, rotatable, cylindrical carrier 2 on to a similar insulating carrier 1 and vice versa, whereby a variable length of conductor may be inserted between a conductive, sprung contact 4 and a further sprung contact 9 which engages a slip-ring 8 connected to an anchorage on the carrier 1 for one end of the conductor. The other end of the conductor is anchored by a screw 16 to the conductive carrier 2. That portion of the conductor which is wound on the carrier 2 is short-circuited and rendered ineffective. Both carriers are provided with spaced spiral grooves for the conductor and are connected together by gearwheels to rotate together at the same speed. The conductor 3 is made of lossy material such as steel wire. An outer metal shield 12 provided with a longitudinal slot 22 and an inner metal shield 11 together form the earthed electrode of a condenser whose other electrode is formed by the turns of wire upon the carrier 1. Thus, as the carriers are rotated to vary the length of the line a variation in the shunt capacity is obtained.
