Title: Improvements relating to fluid pressure operated variable load vehicle braking apparatus
IPC: B60T8/18
Filed: 1953-12-16
Abstract: 725,548. Variable load braking apparatus. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Dec. 16, 1953 [March 10, 1953], No. 35020/53. Class 103 (1). The invention relates to a valve assembly for variable load braking apparatus in vehicles and as shown it operates to pass air from a supply port 4 connected to the brake cylinder to an outlet port 10 connected to a variable volume chamber. Supply port 4 is connected to a supply chamber 5 and outlet port 10 to an outlet chamber 6, communication between the chambers 5 and 6 being controlled by a valve 9 urged against a seat 8 by a light spring 11. The valve may be lifted off its seat by a spindle 12 operated by thrust through a member 38' of a leafspring arm 47 having a fixed pivot at one end and connected at the other end by link 50 to a spring buckle 49 of the vehicle. Since the valve is operative to pass air from the brake cylinder into a variable volume chamber, it is arranged that the spring arm 47 shall take up a position 51 if the vehicle is empty, and is moved to a position 52 as the vehicle becomes loaded so that the thrust on spindle 12 is thus reduced and there is less tendency to open the valve 9 to pass air to the variable volume chamber. If the valve was operative for passing air directly to the brake cylinder, it would be necessary to make the valve open increasingly with load. Since the pressure in the outlet chamber 6 is operative upon the right hand side of a diaphragm member 19 secured to the valve spindle, the valve tends to close as soon as a pressure proportionate to the vehicle load has been attained. Movements of the valve spindle are damped by plates 26 and 27 secured thereto which displace liquid in chambers 24 and 25 through a restriction 22. In a further embodiment described in which the valve is used to vary the pressure in a reservoir, an exhaust port is formed by an axial bore through the valve spindle

Title: Method of tool control
IPC: G05B19/4103
Filed: 1973-07-27
Abstract: 1439373 Interpolation XENEX CORP [27 July 1973 35975/73 Heading G3N In the control of a tool drive in at least X and Y co-ordinates, in which a tool path is represented by a plurality of segments{e.g. (70, 72), Fig. 3 (not shown)}, the tracking of a given segment is terminated when the value of a function representing the distance of current X & Y values from the succeeding segment changes sign. The function may include an offset allowance, to allow for tool width. If the succeeding segment is linear, the function represents the perpendicular distance from current X, Y values to the succeeding segment plus offset correction, or, for a circular succeeding segment, the length of a line from the above X,Y to the circular segment, and perpendicular thereto at the point of intersection therewith, plus offset correction. Algebraic expressions for both these distances are given. In tracking the current segment, the same functional forms, for a linear, resp. circular segment, are used as a measure of deviation of the actual path from the current segment{still including offset allowance}and are kept as close as possible to zero during incremental tool motion under control of X & Y pulses. When the sign of the distance passes through zero, the succeeding segment becomes the current segment and what was the distance signal becomes the initial deviation signal. Alternatively the register storing the deviation is reset to zero when the distance signal changes sign. Computer 22 calculates a new, initial distance signal, relative to the next succeeding segment. For providing a circular fillet between linear segments (80, 82) Fig. 22 (not shown), the actual current X,Y values may be replaced by "pseudo" values representing a line parallel to (80), and passing through the centre of arc 86. When the distance signal for the "pseudo" path changes sign, the tool then follows the arc 86. The tool may be controlled in three;axes, and segments other than circular or linear may be used. Circuitry for unit 20 is detailed in Figs. 4-21 (not shown). A computer program is disclosed.

Air enters centrally of the machine below a baffle, and after passing round the ends thereof, is withdrawn from a central position above the baffle into a duct provided with a fan which supplies the air in a similar manner to the next compartment. In the form shown, divisions b, b<1> divide the casing a into compartments c, c<1>, c<2>. Baffles d and d' are provided in compartments c<1>, c<2>, and a row of steam pipes s is provided between each two adjacent stretches of the fabric e. Air admitted at the ends of the bottom compartment c is drawn into openings such as o<1> provided in tubular members o communicating with openings j, past the fan m, through openings j<1> and tubular members, and into the space beneath the baffle d. After passing round the ends of this baffle, the air is again drawn out, by a fan m<1>, and is supplied to the space beneath the baffle d'. From this upper compartment c<2> the air is exhausted through openings j<4> and r, r<1>. Thus, on entering the drying chamber the fabric is treated with hot, moist air, and in passing through the machine encounters gradually cooler and drier air. The openings in the tubular members o point respectively fore and aft of the machine, and are provided with midfeathers to divide and distribute the air streams.
