Abstract: The  invention  relates  to a self monitoring/calibrating phased array radar in which the operating path for transmission and the operating path for reception may  be monitored/calibrated  by  the  addition  of  a corporate calibration network coupled at the plural end to the antenna elements and at the singular end to the exciter/receiver,  and  switching means to selectively route the monitoring/calibrating signal derived  from the exciter  in  a  transmit  path  to calibration path sequence  or  in  a  calibration  path  to  receive path sequence.      In one embodiment of the invention, a phase shifter common to transmit and receive paths is adjustable in increments  under  active  logical  control  for  calibration, while power and gain performance is monitored but not actively controlled.  A novel T/R sub-assembly houses  the  operating  electronics  for  four  antenna elements in the form of four T/R modules with a one to four divider network in the transmit/receive path and in the calibration path.  The four antenna elements are an integral part of the T/R sub-assembly.

Abstract: The invention is concerned with treatment of gelatins, so as to remove or reduce off-flavours.  It has been determined that the off flavour may be reduced by membrane filtration to remove a low-molecular weight fraction.            The invention provides gelatine substantially without a low molecular weight fraction and a process for the purification of gelatine which comprises removal of a low-molecular weight fraction by membrane filtration.            While it is difficult to be precise about the substances responsible for the off-flavour, it is believed that 4-and 5-methyl indane are removed by the filtration. Accordingly, a further aspect of the present invention provides gelatine substantially free of 4- or 5-methyl indane, and a gelatine preparable by membrane filtration under such conditions as to substantially remove 4- and 5-methyl indane.  While it is not confirmed that the methyl indanes are the per se cause of the off flavour it is proposed that the off flavour promoting species are removed under conditions which also remove the methyl indanes.

Abstract: METHOD AND APPARATUS FOR IMPROVING THE   REGULATION OF THE SPEED OF A MOTOR                          Abstract An automatic braking and speed control for a device driven by an electric motor. A controller provides a pulsed output voltage having a pulse wide dependent upon the load seen by the motor (16). When the drive pulses are present two diodes (52,54) and a transistor (66) serve to maintain a power transistor (56) in the off condition. When the controller is not providing drive pulses and the motor (16) is being turned by the momentum of the mechanical device or by some outside force, such as gravity, the motor (16) functions as a generator and turns on two transistors (56,67) so that two resistors (51a,51b) apply a load to the generator (16). This provides a braking action between the output pulses so that the net speed of the motor (16) and its associated mechanical device is more dependent upon the output pulses provided by the controller. A shunting diode (42), in conjunction with two resistors (51a,51c) provides a braking mechanism in the event that the motor (16) should begin turning in a direction reverse to that desired. A switch (64) allows reversing the polarity of the voltage provided to the motor (16) so that the motor (16) may be made to run in a clockwise or a counterclockwise direction, as desired. The result is an apparatus which can be easily retrofit onto existing systems so as to provide for automatic braking and improved speed control for a device driven by an electric motor.

Abstract: DEVICE FOR SENSING CONTINUITY IN A CIRCUIT HAVING AN OPEN CIRCUITED APPARATUS               Abstract of the Disclosure The  two  wire  device  tests  the  continuity  of conductors  in  a  monitoring  circuit  having  an  open circuited apparatus.  The device has a switch which is controlled by  a  sequencer  and  a  clock.    Upon  the application of power, the device is energized if the continuity of the conductors is present.   The clock provides a train of pulses that alternately opens and closes  the  switch.    When  the  switch  is closed, continuity  across  the  conductors  is  provided  to illuminate an indicator lamp.  When the switch is open, a  power  storage  unit  charges  from  the  monitoring circuit power supply.  The power storage unit provides operating power to the sequencer and the clock.   The output of the clock has a long duty cycle so that the time when  the  switch  is  open  is very brief,  thus causing  the  lamp  to  be  perceived  by  a  human  as unaffected.    The  sequencer  counts  the  number  of oscillations  produced  by  the  clock  and  when  a predetermined number has occurred, turns off the clock and leaves the switch open.   In another aspect,  the circuit has parallel branches with a device on each branch.  The devices communicate with each other on the conductors to determine if continuity exists in each branch before illuminating the lamp.

Abstract: An extract component is separated from a raffinate component contained in a feed mixture by a process in which a unidirectional fluid flow system is maintained through a series of separating units through which the components travel at different rates. A component concentration distribution is established within the system of units and divided into specific zones. Feed and displacement fluid are passed into the inlets of two of the units and extract and raffinate are taken as the entire streams from outlets of two of the units all at appropriate points on the component concentration distribution. Other inlets and outlets of the various units lying in the same zone are interconnected. At the appropriate times the inlets and outlets are shifted so as to simulate movement of the units in a direction co-current with the fluid flow and thereby enable the inlets and outlets to continually lie in the appropriate zones. Zones may be combined as zone pairs, each such pair thereupon being considered a single continuous zone.

Abstract: A single-core electrical power cable for use at 400 kV for example has a relatively high-resistance inner shield located between and insulated from the central core of the cable and its low resistance metallic outer sheath. The inner shield is kept continuous throughout the cable run of installations where, for avoidance of currents circulating in the cable sheath, the sheath continuity is broken at spaced-apart locations. By virtue of such continuity, the inner shield provides a continuous path for surges developed in the cable as the result of lightning strikes or switching operations thereby preventing the development of corresponding high transient overvoltages at the outer cable sheath and particularly at the discontinuities therein. It is thus possible to dispense with the surge voltage limiters previously required to be coupled to the outer cable sheath at intermediate positions of cross-bonded systems.
