Title: Proportional and Integral Action Controller for Sampled Data Control System
Inventor: TAKADA KEISUKE
IPC: G05B11/42
Filed: 1967-05-31
Abstract: 1,190,955. Automatic sampling control. TOKYO SHIBAURA ELECTRIC CO. Ltd. May 31, 1967 [June 2, 1966], No.25110/67. Heading G3R. In a proportional plus integral sampling control system, error signals are applied to a correction amplifier the output of which is stored during sampling periods and applied to the amplifier during succeeding intervals, the amplifier output also being separately stored during the intervals and applied to the amplifier during succeeding sampling periods. In Fig. 2, a signal corresponding to deviations of a variable from a reference valve is continuously applied to terminals 20a, 20b and periodically sampled by repeated synchronous operation of the switches shown. Closure of switches 21a, 21b during sampling introduces an adjustable RC network 25, 26 to add an integral component, and closure of a switch 27c applies the resultant through an amplifier 29 to correct the variable by controlling a device 23. Capacitive feedback is provided by a condenser 32. During sampling closure of a switch 27d charges a condenser 31 with the feedback voltage so that during the succeeding interval its voltage, applied as shown to the input of amplifier 29, maintains the output of amplifier 29 unchanged. During the closure of a switch 21d charges the feedback condenser 32 with the feedback voltage, and opening of switch 21b isolates integrating condenser 26, so that these condensers retain their charges to avoiddisturbance in the succeeding sampling period. Use of transistors instead of switches, and inclusion of pneumatic actuators are referred to.

Title: Improvements in or relating to densitometers for measuring the specific gravity of liquids
Inventor: HONICK KENNETH ROBERT
IPC: G01N9/20
Filed: 1952-10-15
Abstract: 731,702. Determining specific gravity.SIMMONDS AEROCESSORIES, Ltd. Oct. 15, 1953 [Oct. 15, 1952], No. 25806/52. Class 97 (3). A remote indicating densitometer includes a float totally immersed in a liquid to tend to rise or sink therein to a position determined by a stop, remotelycontrolled magnetic means acting against the tendency, and remote means indicating when the action of the magnetic means is sufficient to shift the float from the stop. As shown in Fig. 3, a. cylindrical casing 13 immersed in the liquid, the specific gravity of which is to be determined is divided by a partition 15 into a liquid-tight chamber 16 and a chamber 17 which liquid may enter through holes 18 in the walls. An electromagnet 11 is housed in chamber 16. The leads to magnet 11, and to contacts 19, 20 on the underside of partition 15, are connected to a three-way connector 21. A hollow cylindrical float 12 is guided for up-and-down movement in chamber 17 by rods 25, 26, 27, and is weighed by lead shot 22 set in resin cement so that it just sinks in the densest liquid to be encountered to rest on adjustable stops 28, 29, 30. Magnet 11 is excited., by an increasing currentuntil its attraction for an armature 23 on the float raises the float until a silver contact strip 24 thereon bridges contacts 19, 20. The increasing current is applied by a potentiometer 33, Fig. 1, connected across D.C. supply terminals. 31, 32. When contacts 19, 20 are bridged a lamp 36 lights, and the current through the magnet, measured by a meter 35, gives an indication. of the specific gravity of the liquid. If desired, meter 35 may be ommited and the setting of potentiometer 33 used to indicate specific gravity. Where an A.C. supply is used, Fig. 2, contacts 19, 20 are omitted. Magnet 11 is of horse-shoe form and is shunted by a condenser 40. Current from the potentiometer through the magnet also passes through a rectifier bridge 43 supplying a coil 45 of a device 46 which may be a relay. Current also passes through a resistance 41 to a rectifier bridge 42 to a second coil 44 of the relay 46. coils 44, 45 act in opposition so that relay 46 is not actuated until the float is raised and armature 23 bridges the poles of magnet 11. Condenser 40 is so chosen that it forms with magnet U when its poles are bridged to a tuned circuit resonating at the supply frequency. The change in current in coil 45 causes the relay to operate, and the current in coil 44, measured by meter 35, is a measure of the specific-gravity of the liquid. Alternatively the potentiometer setting indicates the specific gravity, as above. In either of the circuits shown, the potentiometer may be driven by a motor. The rise of the float may interrupt the current supply to the motor, or the potentiometer may be circular and continuously driven, recording means being actuated when the float rises during each revolution.

Abstract: 242,430. Willatt, F. H. Nov. 1, 1924. Lace. - Looped fabrics somewhat resembling knitted fabrics but less liable to ladder are made on twist lace or like machines by causing slack bobbin threads to loop or hank with the warp threads. The mechanism described in Specification 242,397 may be used for this purpose. Fig. 1 shows a one-and-one ribbed fabric there being a pair of warp threads to each bobbin thread b - - b<3>. The bobbin threads co-operate as shown with warp threads fw - - fw<3>, one from each pair, on the front motions and with the warps bw - bw<3> on the back motions. Other combinations of ribs such snch as three-and-two are obtainable. If all the warp threads coact with bobbin threads on the front or the back motions only a fabric with ribs on one face only is obtained. Fig. 4 shows a fabric in which each bobbin thread b co-operates with three warp threads which plait together. Fig. 5 shows a fabric in which there is provided one warp w - - w2 to each bobbin thread b - - b<2> and each bobbin thread loops twice round each adjacent warp while adjacent bobbin threads rest. Other patterned fabrics can be made by preventing bobbin threads which otherwise would loop with warp threads from doing so at predetermined intervals.
