Title: Transcendental function generator

Abstract: 1,242,142. Transcendental function generator. RCA CORPORATION. 30 Aug., 1968 [7 Sept., 1967], No. 41540/68. Heading G4A. The invention relates to a transcendental function generator that can generate hyperbolic or tangential sine and cosine functions as a result of a two-part evaluation, i.e. a divisionlike operation followed by a multiplication-like operation. A vector rotation can be performed in a number of fixed angular increments where R is the radix of the number system used. In Fig. 2 where, for a vector of unit length Y i  = sin #, X i  = cos #. If Z i = R<SP>i</SP>Y i  and rotations in both clockwise and anticlockwise directions are possible and R = 2, Using a binary system of numbers R=2. The values of qi above determine the direction of rotation of the vector and are determined by division-like operations as quotients. If the angular constant is added to # the quotient is "0", if subtracted the quotient is "1", the values of the quotient Q then controlling addition or subtraction operations in equations where the powers of 2 represent successive shifts of the number. In these equations the final value when i = i 0  of Z and X give the values sin # and cos # but since in Fig. 2 the length of the vector varied with each rotation a correction factor must be incorporated as the initial value of X. A flow chart of the division-like operations producing Q and the multiplication-like operations producing the final values of X and Y is given in Figs. 7 and 8 (not shown). The system performing the calculations is shown in Fig. 3. Registers X-AR, Q-AR are cleared and the argument # is transferred from the Master Storage Unit MSU to register Z-AR. The Count Register CR is cleared and program instruction words are entered into IR from the MSU. A constant Ki for i = i 0  is loaded into register X-AR. The sign of the Z-AR register is determined and if negative the appropriate Q bit is set to 0. If positive the appropriate Q bit is set to 1 and the X number is added to or subtracted from the Z number respectively. If i is less than n - 1 it is incremented by 1, the appropriate registers are left shifted and the process is repeated. If i = n - 1 then Q has been calculated and is used to carry out the multiplication-like operation in a process similar to the above Hyperbolic and exponential functions can also be obtained.

A fire brigade ladder of three or more sections extended by a known rope and pulley arrangement has a four-armed locking lever 20 pivoted on the or each intermediate section 2 to ensure sequential extension and retraction of the sections. During extension of the section 1 relative to section 2 lever arm 21 engages a detent 19, preventing extension of section 2 relative to section 3. A cam 18 engages a pin on the arm 23 of the lever 20 when section 1 is nearly fully extended, and rotates the lever to the position of Fig. 4, freeing section 2 which is then extended by the rope and pulley system. A cam 14 on section 3 engages a pin on the arm 24 of the lever so that arm 21 engages a detent 16 on section 1, locking it in position relative to section 2. A resilient detent 25 holds the lever in either of the two locking positions. In another embodiment (Fig. 2, not shown) two two-armed levers are operated in place of the four armed lever. The embodiment of Fig. 9 operates in a similar manner, the arms 31, 32 of the V-shaped lever carrying rollers 34 which are guided in cams 37 and engage detents 38 to lock the sections.

Abstract: 1506489 Moulding heat exchanger tubes UNITED KINGDOM ATOMIC ENERGY AUTHORITY 7 Oct 1976 41647/75 Heading B5A [Also in Division F4] A heat exchanger tube is made by winding a phenolic resin impregnated carbon fibre material upon a metal mandrel and converting the resin to the B stage. The tube 1 thus formed is removed from the mandrel, filled with a particulate conductive material 2, such as graphite powder, and heated to about 80‹ C. to render it deformable by passing an electric current through the conductive material using a pair of electrodes 3. The deformable tube is then helically wound around a second mandrel, removed from the mandrel, slowly heated to about 180 degrees to cross-link the resin, and then further heated to carbonize it. The carbonized tube is finally treated with a hydrocarbon gas such as methane, propene, or xylene to render it gas impermeable. Also disclosed is the heating of the particle filled tube to render it deformable by locating it in an oven.

Abstract: 1529935 Steam turbines BBC BROWN BOVERI & CO Ltd 13 Oct 1976 [15 Oct 1975] 42509/76 Heading FIT [Also in Division F4] In a steam turbine installation, when the load on two-stage turbine 4, 6 is dumped a safety and regulating device 11 calls for closure of governor valve 3 and interceptor valve 7 via signals 14, 16, and if valve 3 fails to close then logic circuit 27 responds to the disparity between signal 14 and a signal 26 from a sensor 25 monitoring the pressure drop across stage 4 of the turbine and after a delay of 0.2-0.5 secs the circuit trips device 11. Upon being tripped, device 11 calls for closure of stopvalves 2, 8 and partial opening of vacuum break valve 20 via signals 12, 18, 21. If valves 2, 8 close, then valve 20 is reclosed after the vacuum has been lowered a small amount. If, however, sensor 25 still detects a pressure differential 1-5 secs after device 11 is tripped then the circuit 27 provides a signal 29 which serves (a) to fully open the vacuum break valve 20, (b) to open valve 34 to admit water to cooling nozzles in the second stage of the turbine, (c) to close down the steam generator (51) which may be part of a nuclear power plant. The device 11  may also be tripped by sensors monitoring other parameters, e.g. bearing temp. A second logic circuit 37 is included which receives signals 16, 18 and a signal 36 from a sensor 35 monitoring the pressure drop across the second stage of the turbine and which responds similarly to circuit 27 if valves 7, 8 fail to close.

The sealing device comprises a pipe having an axially movable collar at each end. A respective sealing gasket is disposed adjacent each collar on the side nearest the ends of the pipe, and a respective ring is placed adjacent each gasket. Axial movement of the collars compresses the gaskets against the rings thus causing them to radially expand to grip the tube walls beyond the opening. As shown the collars and rings are screwed on to screw threaded portions of the pipe, and the collars are provided with sockets 54 to take a thomas bar or the like. In practice the sealing device is inserted by sliding one end into the enlarged opening until the other end may be inserted in the opening and then moving the sealing device back until both sealing gaskets bear on sound parts of the tube wall. The tube 16 may be one of a plurality of parallel tubes interconnected by longitudinal ribs to form a furnace wall.
