A common sensor 6 for the rear wheels the sensors delivering outputs dependent on rotary wheel speed, an evaluation channel 12 for evaluating the sensor outputs, a switchover device for switching the sensor outputs in turn to the channel 12 and means for sensing the start of a braking operation, such as a brake light switch 23, and acting on the switch over device to switch a front wheel sensor to the channel 12 on the start of a braking operation. The sensors are connected by means of AND gates 7, 8, 9 and an OR gate 10 to a transmission element 11 and the channel 12, the output of the latter being connected by gates 13, 14, 15 to valve arrangements V 1 , V 2 , V 3  controlling brake pressure. The valves may be two-way valves or inlet and outlet valves, in the latter case the channel 12 having two output lines. Gates 7, 8, 9, 13, 14, 15 are connected to the three outputs of a counter comprising two bi-stable trigger circuits 16, 17 and an AND-gate 18, the counter being also connected by means of an AND-gate 20 to an impulse generator 19. In the starting position of the counter pulses cause signals to appear in turn at the outputs of AND-gate 18 and bistables 16, 17, a resetting of the counter into starting position by way of AND gates 21. Timing elements 22 extend the output signal of AND-gates 21 and effect a holding of circuits 16, 17 in the output position until after the disappearance of the generator pulse and the output signal of circuit 17. The closing of the brake light switch 23 permits changeover of a multivibrator 24 which sets circuits 16, 17 into the starting position.

The web to be treated may have an opaque porous structure or it may be well formed and dense, have a basis weight of 40 lbs. per sq. ft. or be fairly closed in structure and non-porous. In the latter case, for example, the arc over which web-to-heated roll contact occurs is restricted by fly rolls and these are preferably positioned so that the web moves to and from the nip in a plane whereby contact is only at the nip. The rolls may be of cast iron or steel and they may be heated by passing steam or other heated fluid through passages in them or by electrical heating coils in them. The calender may have two or more rolls. The web may be passed successively through two or more nips at which successively increasing pressures are exerted on it. The web speed may be as low as 10 ft per min or as high as 2000 ft per min. The calender may form part of a paper-making machine or it may be a separate unit. The calender shown in Fig. 3 comprises rolls 10 to 24, the rolls 14 and 16 being at a high temperature, e.g. 300F, and the other rolls being at a low temperature, e.g. room temperature. Fly rolls 28, 30 prevent the web 26 from wrapping around the rolls 14, 16. More than two high temperature rolls may be provided. with further associated fly rolls. The calender is loaded through roll 10 and driven through roll 24. The finished paper may be used in the production of photographic papers, i.e. carrying one or more lightsensitive silver halide emulsion layers, especially papers intended for manufacture of photographic paper base of the resin coated type used for photographic papers used in diffusion transfer processes.

Abstract: 1443543 Grinding SARATOV POLITEKHICHE INST and TRETY GOSUDARSTVENNY PODSHIPNIKOVY ZAVOD 6 Dec 1973 56661/73 Heading B3D A method of machining a workpiece 2, Fig. 1, such as a bearing race comprises linearly displacing the workpiece and a grinding wheel 1 relative to each other, and rocking the grinding wheel about its axis through an angle α, the peripheral speed of the grinding wheel being no more than 100 m./min., and the peripheral speed of the workpiece being not less than seven and a half times that of the wheel. In apparatus for carrying out the method, the workpiece is rotatably mounted on a table 3b, Fig. 3, movable along a pair of guides, and the grinding wheel is mounted on a spindle 19 carried by a saddle 3c movable along transverse guides. The grinding wheel 1 is mounted on one end of the spindle 19, the other end of which has a pulley 18, Fig. 5, by which the wheel can be continuously rotated during rough and fine grinding. During finishing the grinding wheel is rocked by oscillation of a shaft 9 which is axially movable by a piston 16 in a cylinder 17 to engage a friction lining 32 on a disc 31 at one end of the shaft with the pulley 18. The shaft is rotatably mounted in the piston 16 and is keyed to a gear 8 engaging a rack 7, Fig. 4, the gear being in two parts 11, 12 whereby backlash between the gear and rack is eliminated. The rack 7 is secured to a piston 44 reciprocatable within limits determined by adjustable stops 49, 50 to effect rocking of the shaft and hence the grinding wheel when the friction lining 32 engages the pulley 18. The magnitude of the angle α is determined by a control consisting of a fork 53, Fig. 6, which is secured to the shaft 9 and has adjustable screws 54 for actuating a lever 55 of a slide valve controlling the hydraulic or pneumatic pressure supplied to the cylinder 5 of piston 41. In operation, upon actuation of the slide valve, piston 41 is displaced to cause movement of the rack 7 and angular movement of the shaft 9. Simultaneously, piston 16 is moved to engage the friction lining 32 with the pulley 18. Locking of the shaft 9 causes the fork 53 to move the lever 55 of the slide valve so that the piston 41 moves in the reverse direction, and so on until a timer actuates the slide valve to bring the rocking movement to a stop and to disengage the friction lining from the pulley. The rocking angle may be reduced during grinding to zero, the peripheral speed remaining constant. Rocking of the grinding wheel is stated as causing a reduction in the number of abrasive grains contacting the workpiece, the grains thus becoming loaded and resulting in a higher grade of finish.

Abstract: 1391556 Monitoring nuclear reactors WESTINGHOUSE ELECTRIC CORP 11 Dec 1972 [10 Jan 1972] 57005/72 Heading G6C [Also in Divisions G1 and H4] A system for displaying a profile of a parameter monitored over a defined area divided into a plurality of zones comprises a sensor positioned to monitor a part of a zone, each zone having and associated sensor, means to provide interpolated values of the parameter corresponding to the zone parts not directly monitored and a display which displays the profile of the parameter over the defined area. The system is applied to display of the profile of temperature in the core of a nuclear reactor. Each group of four fuel assemblies is monitored by a thermocouple connected to one of the assemblies and the thermocouple outputs are connected via suitable circuits to a resistive matrix whose nodes represent the fuel assemblies. Resistances between the adjacent nodes provide interpolated values at those nodes not having associated thermocouples. Outputs from the nodes are representative of the temperatures in the assemblies and are displayed, in a pattern corresponding to the pattern of assemblies in the core, either on a luminescent display (Fig. 6, not shown) or on a TV monitor (Fig. 7, not shown). For finer resolution, the resistive matrix is replaced by a resistive plate with terminal areas. In any instance where adjacent nodes receive inputs from thermocouples, there are no intermediate resistances. An alarm is given when any thermocouple output lies outside a predetermined range. The alarm may be given by causing the corresponding area of the display to flash. Similarly, an area of the display is used to indicate thermocouple failure.
