Abstract: APPARATUS FOR LOCATING ACCESS OPENINGS FOR ELECTRICAL OUTLET BOXES IN COVERING MEMBERS     ABSTRACT OF THE DISCLOSURE   The apparatus disclosed includes a locator pin assembly for mounting on the outlet box before the covering member is placed over the box. It includes one or more pins, depending on the type of outlet box, that are attached to and extend perpendicularly from opposite sides of the mounting plate. The pins are sharp on both ends and pierce the covering member when the member is positioned over the box. A template is mounted on the protruding pin or pins to guide a cutting tool as it cuts the access opening for the box. The pin or pins extend different distances on opposite sides of the plate. On one side, the pins extend a relatively short distance for use with relatively thin covering members, such as wood paneling. On the other side, the pins extend a relatively long distance for use with relatively thick covering members, such as wallborad. An extractor is provided to attach the template to the locator pin assembly through the covering member to hold the template in position during the cutting operation and to allow the scrap and locator pin assembly to be removed together through the access opening.

Abstract: ABSTRACT OF THE DISCLOSURE      A memory access control system which is provided between one or more accessing devices and a main memory composed of a plurality of independ-ently accessible logic stores and receives a request from the accessing device based on the status of the main memory to permit access to one of the logic stores. The memory access control system comprises a shift register  composed of stages corresponding to the cycle time of the main memory for storing address information sufficient for identifying a busy one of the logic stores and sequentially shifting  the stored content in synchronism with a clock signal and a comparator circuit for comparing the content of each stags of the shift register with address information of the logic store designated based on the request from the accessing device, receiving the request  based on the result of the comparison and generating a control signal  for accessing to the designated logic store. Using the shift register, one of the logic stores to be accessed can be checked whether it is busy or not, so that even if the number of logic stores is increased with an increase of the capacity of the main memory, the scale of the memory access control system is not enlarged. The shift register has stored therein also the codes of operations, the codes of the accessing devices, etc., and is capable of identification of the accessing device to which data read out from the main memory is to be send back, and a partial write control.

Abstract: ABSTRACT         In a microwave lens of the Rotman type for a scanning beam antenna a plurality of radiating feed probes are spaced along the focal arc.  An illumination function is then commutated around the focal arc by energizing groups of the feed probes simultaneously in accordance with weighting functions to thereby cause the resulting radiated beam to scan in small equally spaced increments while the array factor re-mains essentially constant.  Methods of calculating the weighting func-tions and feed probe spacing are shown.

Abstract: Abstract of the Disclosure A diaphragm-type check valve for vacuum pipes is provided which enables opening of the valve using substantially less operating force than is required in conventional valves of the same size and type.  The valve includes a flexible diaphragm which is disposed in the pipe and is held in its closed position by the vacuum in the pipe.  A mechanical operator such as a vacuum-actuated piston causes opening of the valve.  A cavity located on the side of the diaphram opposite that which is exposed to the pipe vacuum is selectively connected to a source of suction or vacuum (preferably that provided by the pipe itself) so as to substantially equalize the pressure on both sides of the diaphragm and thereby enable opening of the valve with a less bulky operating mechanism that provides only the reduced operating force referred to above.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of contacting gas and liquid is described in which gas and liquid are introduced into a column, the liquid being introduced into the top of the column in the form of a stream of liquid of velocity suff-icient to generate in the upper region of the column a sub-stantially continuous foam.  The geometry of the column and velocity of the inlet stream of liquid are adjusted so that there is a tendency of the incoming stream of liquid to dis-perse and reentrain coalesced bubbles, separating gas or larger bubbles at the top of the column into the foam.  The method can be carried out continuously and very efficiently with economic energy usage.  It is particularly of value in dissolving gases into water, particularly dissolving oxygen into water.

Abstract: CHANNEL SELECTING APPARATUS                   ABSTRACT OF THE DISCLOSURE     Channel selecting apparatus for use with first and second electrically tunable tuning devices.  A selectively operable channel selector, common to the first and second tuning devices, generates and supplies channel selector sig-nals to the first and second tuning devices to determine the tuning condition of both devices.  A control circuit selectively produces a lock-out control signal; and a locking circuit is coupled to the second tuning device and is responsive to the absence of the lock-out control signal to enable the tuning condition of the second tuning device to be determined by the channel selector signals at the same time that the tuning con-dition of the first tuning device is determined by the channel selector signals; the locking circuit being responsive to the presence of the lock-out control signal to lock the second tuning device to the tuning condition which was determined by the channel selector signal generated immediately prior to the lock-out con-trol signal, regardless of the subsequent generation of different channel selector signals.         One advantageous application of the channel selecting apparatus is with a common channel selector for use with a tele-vision receiver and with a VTR, wherein it is necessary to prevent the broadcast channel to which the VTR is tuned from being changed during a recording operation, even though the television receiver can be tuned to any other different broadcast channel, -i-
