Title: Emergency trip device
IPC: F01D21/18
Filed: 1976-06-18
Abstract: The emergency triggering means is arranged in the hydraulic line via which the main valve of a steam turbine is controlled. An inlet line (33) is connected, via an inlet valve (24) which is closed in the rest state by a spring (21), to a chamber (35) which is connected, via an outlet line (37), to the actuating means of the main valve of the turbine. A second branch of the inlet line (33) acts, via an orifice plate (39), on the one hand, on the actuating piston (17) of the inlet valve in the opening direction and, on the other hand, on a disc-shaped outlet valve (50) together with a spring (59) in the closing direction. During normal operation, the inlet (33) is therefore connected to the outlet (37) and the inlet pressure acts on the actuating mechanism of the main valve. In the case of disruption, the second branch of the inlet line is emptied, via a further valve (70), to a return flow (77). The inlet valve (24) closes, and the outlet valve (50) opens the chamber (35) to the return flow (77), with the result that the main valve of the turbine closes rapidly. All three valves in the emergency triggering means are designed as seat valves, and this permits reliable operation. <IMAGE>

Title: Improved abrasive wheels
IPC: F01N1/04
Filed: 1955-09-09
Abstract: An abrasive wheel of bonded abrasive grains has at least one pre-formed reinforcing ring adherently affixed approximately concentrically within it, the ring comprising a number of continuous glass filaments that extend generally in alignment with the annular contour of the ring and are embedded in and individually surrounded by a strong abradable unifying binder matrix for uniting and protecting the filaments.  A ring may be formed by winding glass yarns, each consisting of a large number of loosely twisted filaments, on a grooved mandrel, the binder matrix being a reaction product of bisphenol A and epichlorohydrin, with diethylene triamine as accelerator.  The bond for the abrasive may be powdered solid phenolic resin, or a rubber composition comprising smoked sheet natural rubber, sulphur, polysulphide polymer, zinc oxide, accelerators and antioxidants.  Alternatively, a polyethylene coated kraft paper lining is coated with a liquid composition comprising rubbery butadiene-acrylonitrile copolymer, zinc oxide, oil-soluble phenol-aldehyde resin, esterified pinewood resin insoluble in petrol, salicylic acid, dibutyl phthalate and methyl ethyl ketone and dried at less than 150 DEG  F.  The exposed surface of the coating is reactivated with methylethyl ketone solvent and coated with a single layer of glass yarns, each formed of 204 loosely twisted hair-like continuous glass filaments and having approximately 100 yarns per inch of width laminated thereto; the yarns run lengthwise of the sheet and are parallel to each other.  The sheet is then coated with further composition, and the sheet dried at less than 150 DEG  F. The liner is stripped from the sheet which is then wound under slight tension to a thickness of about 20 ply on an aluminium mandrel preheated to about 200 DEG  F.  The mandrel with the winding thereon is then cured at 200 DEG  F. for two hours, cooled and disassembled. The formed cylinder is slit, along planes perpendicular to the axis, into rings.

Title: Counter structure
IPC: G06M3/00
Filed: 1975-06-18
Abstract: 1504958 Counters SUN OIL OF PENNSYLVANIA 18 June 1975 [17 July 1974] 25921/75 Heading G4D In a counter such as that described in U.S.A. Specification 2,814,444 an arm 20 supported by but not rotatable about the shaft of the number wheels carries buttons 26, e.g. of nylon, which frictionally engage the driven gear 12 of the lowest order number wheel to prevent overrunning when the drive is stopped. The counter is employed in a petrol dispenser; with increasing prices it is necessary to reduce the speed of the counter by a factor of 10 and give the lowest wheel 100 graduations so as to increase the total price displayed; the braking action of the buttons 26 ensures accuracy of the display. The Specification also describes a more accurate resetting mechanism for the counter. The counter wheel comprises a numeral drum 30 attached to a hub 23 upon which is loosely mounted the driving gear 12. The gear 12 has an annular indented portion 31 bearing teeth 39 which in the counting condition co-operate with a coupling blade 33 which is pivoted in a slot in the hub 23 so the gear and drum rotate as one. For resetting the shaft is moved axially so that a part 41 of the blade 33 is forced out of an annular groove in the shaft and disengages the drum from the gear. At the same time another blade similarly mounted is forced out of the groove and a allows a spring driven plunger 45 to couple the drum to a resetting gear 52 whereby the drum is driven back towards zero. At the zero position the blade 36 drops back into a longitudinal slot 53 in the shaft 11 to disengage the drive. To increase the accuracy of the zero position the blade 33 has an arm 38 which in the resetting position is axially aligned with a latch 54 pivoted to fixed part of the structure adjacent the rim of the drum 30; in the zero position the latch 54 snaps into engagement with the arm 38 to accurately determine the zero position. If the drum is at 1 or 99 when resetting the blade 36 can drop prematurely into an oversized or worn slot 53 so that no resetting drive occurs. To prevent this latch 54 has an arm 67 which when the latch is displaced by arm 38 pivots a linkage 65-69-71 which pushes the blade 36 out of the slot 53 until the drum is properly reset.
