[Class 46.] Steam released from the boiler sludge water is used for heating the feedwater in the second, heating, stage of the process for purifying feedwater, described in the parent Specification and which consists in subjecting the water to chemical treatment and then heating it at high temperature and pressure. The water may be passed through a preliminary heater b into the chemical treatment tank a and thence by a pump p through pipes g, e, to a heater c, from which it is delivered to the boiler D through pipes l, m, by a pump q. The heater c is fitted with a ribbed contact device d. Sludge water passes from the boiler through a pipe o either direct to the heater c or through a vessel k in which steam separates for delivery to the heater through a pipe r, the sludge being passed through a pipe i to the tank a. Steam from the boiler may be supplied to the heater through a pipe f with pressure-reducing valve f<1>. Sludge from the heater c may be passed to the tank a through a pipe h in which a separating device similar to the vessel k may be inserted. In the latter case the steam so separated is passed to the heater b or tank a. The treated water may be passed from the heater c to a storage tank in which water from condensers is collected and from which the boiler is supplied. The steam from the separator k may be sufficient to treat in the vessel c the smaller quantity of fresh feedwater then required. Steam carrying with it any air or gas separated from the water in the vessel c passes away through a pipe x and is used to drive the pump p.

Abstract: 112,230. Trethewey, W. G. Dec. 27, 1916. Ploughs.-A motor-plough provided with creeper chains l has its ploughs 8 attached by links 6 to an inclined cross-bar 1 extending between the side frames 2 and the ploughs are adapted to be raised at their rear ends by links 23 connected to hand-levers 20 pivoted on a platform 18 pivoted at the rear end of the main frame. The points of the ploughs 8 may be raised or lowered by adjusting pins 11 passing through the links 6 in one or other of a series of holes provided at the front of the plough beams. The beam of each plough 's kept in position by a cranked keeper bracket 12. To prevent each plough digging in, a curved plate 13 is adjustably secured to the underside of its link 6; a knife secured to the plate 13 acts as a coulter. The levers 20 are provided with the usual pawl and ratchet control, but the rear parts 22 of the ratchet sectors are cut away to lessen the wear of the pawls. The motor conveys motion through a gear box and differential gear to chains n which drive the wheels h, over which the creeper chains l pass, through short shafts m and pinions h<1>. The creeper chains also extend over wheels k mounted in bearing blocks adjustably and eccentrically mounted in the forward ends of separate frames i which are pivoted on the axle of wheels h and connected together at their forward ends by a spring j. The creeper chains are formed as shown in Figs. 6 and 7. The forward ends of the frames i with the wheels k may be lifted to facilitate the steering of the machine by the operation of a drum o which can be driven in either direction from a shaft u secured to the main shaft of the motor. The drum is stopped to lock the frames i at any desired height by a block z<2> which is pressed by a spring against the edge of the bevel friction wheel t. The block is forced back to permit the rotation of the wheel by the operation of a lever y which forces a pin on the lever w out of a recess in the upper edge of the spring of the block. A buffer i<2> is provided to engage the frames if lifted too high. The forward end of the shaft u is provided with a pulley u<1> to drive any stationary machine. Steering is accomplished by a steering-wheel b operated through a worm wheel and worm. Specification 106,648 is referred to.

Filed: 1945-03-21
Abstract: 589,408. Printing machines; printing - surfaces; feeding sheets. CLAFF, C. L., CLAFF, C. E.; and MOELLER, C. A. March 21, 1945, No. 7205. Convention date, March 25, 1944. [Classes 100 (i) and 100 (ii)] An offset press which is especially adapted for reproducing typed matter or drawings formed on a paper or metal planographic printing-plate is constructed with a plate cylinder 30 arranged vertically above an offset cylinder 10 in a U- shaped frame 16, and an impression cylinder 126 mounted in pivoted arms 130 vertically below the offset cylinder. The cylinder 30 is normally pressed by springs 46 into contact with the cylinder 10, the movement of the bearing blocks 36 being limited by a screw stop 58. The cylinder 30 can be held out of operation by sliding cam bars 50 (Fig. 4) having slotted ends of variable thickness through which pass bolts 42 with nuts 44 which are engaged by thin ends of the bars 50 to permit the cylinders to engage, and bv thick parts to permit the cylinder 30 to be held out of action. The printing-plates are damped while the rollers 30 are tripped by means of a reservoir roller 86 mounted in pivoted members 80 hooked to pins 100 on the frame, and the roller may be removed from the press after damping and supported by a three point support comprising two extensions 96 of the members 80 and the end of a handle 94. Or the member 80 may be engaged by a pin 116 on pivoted members 110 to trip the damping roller.- In some cases the roller 86 may act continuously. The inking roller 120 is mounted similarly to the damping roller, and it is supplied with ink from a plate 163 which may serve to enclose the rollers during transport together with a plate 144 which serves as a detachable feed table, which in operative position is held by screws 148 to a fixed part of the table. The impression roller 126 is mounted in pivoted arms 130 (Fig. 4) and normally is held out of printing position by gravity. A bar 134 secured to the arms 130 rests on an arm 136 of a shaft 138 fitted with an actuating arm 140 (Fig. 1) which is depressed to bring the roller 126 into operative position. This takes place when a sheet is placed on the table 144 in a position determined by adjustable back and side gauges 156, 150. The handle 18, which rotates the roller 10 and by means of gears 20, 84, 142, the other rollers, is rotated clockwise from a position controlled by a mark 158. The printing-plates are formed with perforated ends which are engaged by fixed hooks 66, and hooks 68 (Fig. 6) secured to slotted levers 72 controlled by a bow-shaped spring 76 secured to a gap 62 in the cylinder by means of a central screw 78. The pins 68 are received in recesses 75 in the cylinder.

Title: Magnetic core binary counter
IPC: H03K23/76
Filed: 1963-02-22
Abstract: 956,756. Magnetic storage devices. AMP Inc. Feb. 22, 1963 [March 15, 1962], No. 7242/63. Heading H3B. [Also in Division G4] A magnetic core cascade counter comprises in each stage a number of multiaperture cores arranged in gating relationships, a first input pulse setting a stage into such a condition that a pair of cores oscillate between two states in response to control currents until a second input pulse has been applied to the stage. Multi-aperture cores of the type generally described in the shift register of Specification 899,366 with set, priming, and transfer windings are assembled in groups of four to each stage, Fig. 1. Transfer of " 1 " is effected from cores Y and X by A clock or advance pulses and from cores Z, W by B pulses, Fig. 3, the advance pulse leads extending through the main apertures not being shown. The first input pulse sets Y to " 1 " through minor aperture 20. Cores X, Y and their transfer windings are arranged to form an " Exclusive OR " gate so that Z is set only when " 1 " is advanced from X or Y but not from both. So, after " 1 " has been entered into Y successive advance pulses transfer it to Z and then to X and back to Z and so on. Cores X, Y are also arranged to form an AND gate so that when Y has been set by a second input pulse the next A pulse sets W. The succeeding B pulse clears W and transfers " 1 " to Y of the next stage. As shown at line 9 of Fig. 3 while a stage is in state " 1 " read-out coil 90 of core X produces a succession of alternately poled read-out pulses 86, 88. In Fig. 5 the first pulse sets all stages to " 1 " and subsequent pulses effect a count down, one by one on the binary scale. Modifications are described with reference to Figs. 4 and 6 (not shown).

Title: Improvements relating to accelerometers
Inventor: BARNES JEFFERY WALTON
IPC: G01C21/16
Filed: 1966-02-19
Abstract: 1,109,615. Gyroscopic apparatus. FERRANTI Ltd. Feb. 9, 1967 [Feb. 19, 1966], No. 7378/66. Heading G1C. A double-integrating accelerometer, for measuring the distance travelled by a vehicle on which the accelerometer is mounted, comprises a gyro rotor 16 mounted in inner and outer gimbals 12, 10, a housing 14 enclosing the rotor and carrying the stator 17 of the rotor driving motor, the housing being mounted for limited angular movement about the rotor spin axis 15, a mass 18 attached to the housing 14 so as to render it responsive to acceleration forces acting on the gyro other than in the direction of the axis 15, a pick-off 20 to detect angular rotation of the housing 14 with respect to the inner gimbal 12, the pick-off being connected to a control unit 22 which varies the speed of rotation of the rotor from a datum speed in accordance with the sense and magnitude of the pick-off output by controlling the feed to the stator 17, and a pick-off 26 to monitor the speed of rotation of the rotor and feeding signals to a comparator 28 also fed with signals representing the datum speed from a reference source 27, the difference between the actual rate of revolution of the rotor and the datum speed thus being determined and this will be indicative of the acceleration forces acting on the accelerometer. In operation if the vehicle accelerates along the direction of the arrow A the housing 14 is rotated due to the provision of the mass 18. The pick-off 20 provides a signal to the control unit 22 to accelerate the gyro rotor 16 for example. The reaction to this will cause the housing 14 to rotate in the opposite direction and return substantially to its original position. If the vehicle ceases to accelerate the gyro rotor will be maintained at its increased speed. The distance covered by the vehicle is determined by counting the difference between the number of revolutions of the rotor and that of a motor running at the datum speed. The pick-off 26 gives a pulse train with a frequency dependent on the rotor speed, and a counter 29 connected to the comparator 28 is calibrated in distance travelled. Alternatively, the pulse train may be used to drive a motor connected by differential gearing to a motor running at datum speed, the gearing having an output shaft one revolution of which represents a fixed distance. Also, the acceleration acting on the gyroscope may be used to decelerate the gyro rotor 16. The mass 18 is balanced by a mass 19 on the inner gimbal 12 and this mass together with the pick-off 26 may be mounted for rotation about the axis of the housing 14 to enable them to be positioned in accordance with signals derived from an azimuth gyroscope.
