Abstract: ABSTRACT      A captive dispensing cap construction for a container, comprising a body part having a discharge passage, and a stopper extending upwardly from the passage.  A screw cap part is carried by the body part and has a discharge open-ing into which the stopper extends when the screw cap part is screwed to its full-on position.  The screw cap part and body part have two pairs of mutually engageable portions, one comprising cooperable screw thread means for moving the screw cap part axially on the body part as the cap part is turned, and the other comprising a cam track on the body part and a follower portion on the screw cap part.  The thread means has sufficient backlash to enable the screw cap part to have an initial unscrewing turning movement from its fully screwed-on position through an angle essentially in excess of 20° before axial outward displacement of the cap part occurs.          The advantage of the present invention is that less clogging occurs than with prior devices.  The initial rotation without axial displacement loosens previously crusted product from the screw cap, since the stopper tends to retain part of the crusted product during such initial rotation.  Thereafter, the axial movement of the cap forcibly loosens such crusted pro-duct from both the cap part and the stopper.

Abstract: Process for Recovering a Solid Bitumen Product from Tar Sands Abstract A principal object of the invention is to pro-vide an economically feasible process for recovering bitumen from tar sands.  The process comprises subjecting the tar sand having a particle size not in excess of about minus 1 inch to a drum leach with a light relatively volatile hydrocarbon solvent, centrifuging the resulting slurry to separate the bitumen loaded solvent from sand and distilling the pregnant solvent to recover a solid flaked bitumen product with almost complete recovery of solvent.  As shown in the drawing, the solids from the centrifuging step  are further pro-cessed in a series of successive agitation leach and centrifuging steps as recovered solvent and make up solvent are added to the system, the bitumen loaded solvent from the second centrifuging step being returned to the first leaching step.  Solids from the final centrifuging step are thermally distilled and the recovered solvent returned to the system. As a result of the further processing, a high recov-ery of bitumen is obtained and the pregnant solution sent to solvent and bitumen separation for final solid bitumen recovery is substantially free of fines and particles.

Abstract: Abstract of the Disclosure A subscriber line circuit comprises a controllable DC to DC converter for producing a converter output signal which becomes a loop signal comprising a DC signal and/or a communication signal of a communication fre-quency band.  First and second voltage signals are dependent on the current and the voltage of the loop signal, respectively.  One of the voltage signals is amplified with different transfer functions at DC and in the communication frequency band.  The converter is controlled by an error between a first sum of the amplified signal and the other voltage signal and a second sum of a reference voltage and a signal supplied from an output of an exchange.  A sub-tractor supplies a difference between the exchange output signal and the second voltage signal to an input of the exchange.  Preferably, terminals for connection to a subscriber substation are isolated at DC from terminals for connection to the exchange input and output.  The invention enables subscriber line circuits which are compact, light weight and low power consumers to be realized.

Abstract: Abstract In a stabilising circuit for an inverse rectifier motor control, a genererator is provided for the inverse rectifier frequency that is substantially proportional to a frequency control voltage (Uf).  A control circuit depending on the existing voltage of the intermediate circuit leads the frequency control voltage (Uf) to follow a measuring voltage (?m) which is equal or proportional to the existing voltage.  The freqency control circuit comprises a frequency dependent filter and is so designed that, with increasing oscillation frequency of the A.C. voltage component, the frequency control voltage (Uf) is corrected in two respects relatively to the measuring voltage (Um): 1.  The mean value (?f) of the frequency control voltage is altered relatively to the mean value (?m) of the measuring voltage in the sense of increasing the inverse rectifier frequency. 2.  The amplitude of the A.C. voltage component of the frequency control voltage (Uf) is reduced relatively to that of the measuring voltage (Um).     Fig. 5.

Abstract: APPARATUS FOR CONTROLLING THE COLORS DISPLAYED                 BY A RASTER GRAPHIC SYSTEM                        ABSTRACT     Apparatus for controlling the colors displayed by a raster graphic system, which includes a color cathode ray tube.   The tube is provided with an orthogonal array of picture elements (PIXELS), with each PIXEL having a unique binary address.   An addressable  memory  is  provided  with  memory  locations,  the addresses  of  which correspond  to  those  of  one  of  a  set  of PIXELS.    The  information  stored at  each  addressable  location includes a set of background/foreground control bits and a group of behavior bits.   The background/foreground control bits  are read out of a memory during a memory cycle and stored in a shift register.   At the same time, the behavior bits are read out of the memory and are applied to an escape-code detector and to a foreground behavior register and a background behavior register, each of which is capable of storing a group of behavior bits.          The shift register shifts out one background/foreground control bit  for  each  PIXEL  clock  pulse  which  determines  the  set  of behavior bits stored in the background and foreground registers to be used in forming a color  index.   The color index, which includes a group of behavior bits and the background/foreground control  bit,  is then  used  as  an  address  to  a  color  look-up memory,  and  at  which  each  addressable  location  are  stored typically eight bits which determine the color.   Color control signals read out of the color look-up memory are applied to D/A converters to produce analog signals to control the intensity of the red, green and blue guns of a cathode ray tube.  One set of the  behavior  bits  is defined as constituting an escape  code.          Whenever this particular set of behavior bits is read out of the behavior memory, that set is not stored in either the background or  foreground  behavior  registers.    When  the  escape  code  is detected, the next set of behavior bits read out of the behavior memory is stored into the background behavior register.   In the absence of an escape code being detected, the behavior bits are stored in the  foreground behavior  register.   The bits  in the background  behavior  register  remain  the  same  until  the  next escape code is detected, at which time the next set of behavior bits is stored into the background behavior register.
