Abstract: ABSTRACT OF THE DISCLOSURE        A well bore tubing system for releasably coupling upper tubing strings with lower tubing strings.  The system includes an orienting body connectible on the upper end of a well packer and having a pair of separate laterally spaced longitudinal bores, each having a locking recess and a seal surface, a longitudinal side orienting surface along the body, an upper end male guide surface leading to the orienting surface, an orienting head assembly to releasably couple with the orienting body comprising an orienting head having two longitudinal bores alignable with the bores in the orienting body and a lower end female guide surface engageable with the male surface on the orienting body, a longitudinal orienting arm secured on the guide head having a longitudinal orienting surface engageable with the orienting surface on the orienting body, and a tubular seal and latch assembly secured at one end in each of the bores of the orienting head.  The orienting body is secured on a well packer set in a well bore supporting two lower tubing strings.  Two upper tubing strings are connected with the orienting head assembly and run into the well bore until the orienting arm engages the orienting body turning the orienting head, upper tubing strings and seal and latch assemblies which are aligned with and telescoped into the bores of the orienting body locking the head assembly into the body.

Abstract: DISPENSING CLOSURE FOR A SQUEEZABLE CONTAINER             Abstract A housing is threaded to the container and includes a valve stem having a flexible valve disc member.  In the housing are upper and lower adjacent valve seats which mate with the disc member to form closed valves therewith.  when in contact with the upper seat the valve can be opened and closed by the pressure differential between the container and the ambient.  When manually placed in contact with the lower seat the disc member snaps in place by flexing over the upper seat into a locked closed valve state with the lower seat and does not open in response to pressure differentials between the container and the ambient.

Abstract: Abstract Of The Disclosure A B-scan ultrasonoscope which can be used for scanning tissue, for example the human eye, and displays the shape and character of the tissue.  The echo pulses received are converted into digital signals whose amplitudes represent the reflectivity of the tissue.  The digital signals are then displayed on a color display in accordance with a desired color scale, with individual digital increments respectively representing preselected colors.          Alternate increments are maintained as black, whereby the active colors are interleaved with bands of black.  In this manner, tissue interfaces are more easily seen and visual acuity is improved.

Abstract: ABSTRACT OF THE DISCLOSURE         A color television receiver system has a cathode ray picture tube including an imaging faceplate having deposits of multi-color phosphor targets thereon.  The tube includes a three-beam electron gun and a color selection aperture mask having apertures in registration with the targets.  A beam-current-control signal is derived from the scansion circuit means of the receiver system; the amplitude of the signal varies monotonically as a function of the distance of the beams from the center of the faceplate.  Means are provided for receiving the beam-current-control signal for modulating the receiver system luminance signal with the beam-current-control signal, which has such characteristics that the modulation causes a predetermined gradational reduction in beam current as a function of the distance of the beam from the center of the faceplate.  The benefits include enhanced color purity and improved resolution, and energy savings.

Abstract: ABSTRACT OF THE DISCLOSURE A connector is provided for connecting one type arm end connector to a cross pin of a cross pin-type wiper blade.  The connector has a body portion having a longi-tudinal axis with one part of the body portion receiving the end of a wiper arm and a second part of said body portion engaging the cross pin of the blade.  Said second part has a pin-receiving slot in the forward facing wall and a pair of sidewardly-urged latch legs having contact surfaces spaced from the transverse axis of said pin-receiving slot.  The legs are squeezed together as the pin-receiving slot is aligned with the cross pin and the squeezed legs are threaded between the side walls of the blade.  The legs are released as the slot of the connector is snapped over the pin.  The connector is rotated about the axis of the pin until the latch legs snap out of the opening between the walls of the blade.  The contact sur-faces of the legs are spaced above the edges of the walls of the blade as the connector and its associated arm are articulated relative to the blade through the normal range of blade and arm movement.  The connector cannot be removed from the blade without first squeezing the legs against the body portion and pivoting the connector relative to the blade to move the legs between the walls of the blades whereupon the connector can be pulled transverse to the axis of the blade to unsnap the con-nector from the blade.

Abstract: Abstract A method is disclosed for achieving a draught-free environment within a defined zone of a larger room by using a heating ceiling.  The heating ceiling is in form of a frame having exchangeable foil sheets intend-ed to reflect heat from any heat dissipating bodies within the zone.  The heating ceiling has a heat loop to produce additional heat complementary to the heat reflected by the foil sheets from the bodies so that a constant temperature is kept within the air volume of the zone.  For control of the additional heat there is a sensor arranged in a chimney-like opening.  The sensor is connected to a control circuit.  With the heating ceiling there is obtained a wall-less and thereby an accessible zone having a well defined environment and a substantially constant temperature.  Examples of applicat-ions for the heating ceiling are in the rearing of animals, the treating of burns and the like where maintenance of draught-free environment and constant temperature is important.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a process for producing ethan-ol by continuous fermentation of polysaccharide-containing raw materials.  The fermentation is carried out in one or several fermentors, a flow of fermentation liquor being separated into a yeast concentrate flow and a yeast-free flow, and possibly one sludge flow, of which the yeast concentrate flow is recirculated to the fermentor, at least part of the yeast-free flow being fed to a simple evaporator unit, corresponding to one or a few dis-tilling stages, wherein it is separated, partly into a first vapour flow, enriched in ethanol, which is fed to a plant for production of the desired ethanol grade, and partly into a first liquid bottom flow, which is at least in part recirculated to the fermentor.  Especially characterizing for the new process is, that a raw material flow is fed to a circulation circuit, comprising said fermentor and said evaporator unit, and that the raw mater-ial flow is hydrolysed, in the evaporated unit, to a fermentable state.  It is especially advantageous to carry out this hydroly-sis by enzymes, preferably by a gluco-amylase at a temperature within the range 35°C to 75°C.

Abstract: Abstract of the Disclosure Subscriber access to the television transmissions of a cable TV system or other wired program transmission is governed by switching means in the remotely controlled unit to which the subscriber's receiver is connected, which switching means is enabled or disabled in response to information coded on the power flow which energizes the controlled unit. The power to the controlled unit may be coded at the cable TV power supply in response to a separate modulated RF carrier signal trans-mitted to all power supply units from the cable television broadcast central station, or other central location. Stated in other words, a program control center generates binary coded instructions including address words which are conveyed in a wired signal transmission system to multiple subscriber stations by encoding in a special way the output of a power supply used to supply energization to portions of the system.          Upon comparison of the addresses, each station addressed is directed remotely by the coded instructions to achieve any of a plurality of switching functions, including the selective connection of program materials to the subscriber's outlet.
