Abstract: ABSTRACT A  method and apparatus is provided for continuously hydrolizing finely comminuted fiber material and continuously extracting acid hydroly-sate.  The fiber material is fed into a steam phase at the top of a stand-ing, closed reaction vessel.  In this phase the material is heated to approx-imately 170°C.  Further down in the vessel, the material is exposed to a short liquid phase, concurrent impregnation, and simultaneous short concur-rent hydrolysis.  Still further down in the vessel, in a counter-current part having twice the diameter of the concurrent part of the vessel, the material is exposed to a liquid phase, a countercurrent wash and simultaneous countercurrent hydrolysis with pre-heated wash liquid.  This liquid is intro-duced by distributing means close to the bottom of the vessel and is at a temperature of around 170°C.  Displaced liquid containing a major part of the dry substances in the hydrolysate is extracted and removed from the vessel at the upper end of the counter-current treatment section.  The fiber mater-ial relieved of the hydrolysate is discharged from the lower part of the ves-sel and preferably fed directly to a succeeding sulphate digester.

Abstract: ELECTRONIC SYSTEM FOR AUTOMATICALLY TUNING TO A SELECTED TELEVISION CHANNEL                                 ABSTRACT       An all electronic tuning system is described for establishing a frequency of a local oscillator in a television receiver.  When a channel selection is made, a number representing the desired channel is entered in a memory circuit.  A first plurality of frequencies is generated in response to a channel selection, and a VCO employed as a local oscillator is caused to increase in frequency.  When the VCO frequency differs from the first plurality of frequencies by a predetermined amount, a second plurality of frequencies is generated.          Each frequency generated in said second plurality of frequencies is compared with said VCO frequency.  When a predetermined difference exists between said VCO frequency and said second plurality of fre-quencies, a count is recorded.  When the recorded count is equivalent to the number obtained in the memory circuit, the VCO tuning is inhi-bited and the VCO frequency is stabilized until a subsequent channel selection is made.

Abstract: Abstract of the Disclosure A security device for preventing unauthorized separation of a door from a cooperating buck assembly, in which first and second plate members are respectively car-ried by the door and the buck assembly and cooperate with each other to prevent movement of the door in a lateral direction when the door is closed.  The first plate member is of unique configuration and is arranged to interlock with adjoining structure on the second plate member to keep the door from moving in its plane.  In certain em-bodiments a Z-shaped support element separate from the plate members is mounted on the buck assembly in juxta-position with the second plate member, and in some cases either the first plate member or the second plate member includes a pivotally supported cam element which moves into cooperating relationship with the other member as the door reaches its fully closed position.

Abstract: HIGH VOLTAGE SWITCH MECHANISM           ABSTRACT: Disclosed is an interrupter switch mechanism for interrupting current flow in a high vol-tage electrical circuit.  A tubular switch blade is mounted for linear movement to engage and disengage a stationary contact.  A spring is positioned within the hollow interior of the tubular switch blade so that it can be biased in either direction by sliding plugs also positioned within the tubular switch blade.  The sliding plugs include pins which engage a slot in a plate member so that movement of the plate member in either direction causes one or the other of the plugs to move to bias the spring in that direction.  The plate member has gear teeth formed thereon for engaging mating teeth on a tool engaging disk.  The tool engaging disk has an opening therein for engaging the end of an insulated tool which may be rotated to operate the mechanism.  The plate member also has cam surfaces which engage first and second cam follower members to cause these cam follower members to pivot.  The cam follower members also include stop arms which engage the tubular switch blade and prevent it from moving until the spring is fully biased and then releases the switch blade so that the switch blade will move rapidly to either engage or disengage the stationary contact.  The invention may also include fuse contact members which are operated by the tool engaging disk to engage a fuse or other electrical component when the tool engaging disk is rotated in one direction and to disengage the fuse or component when the tool engaging disk is pivoted in the opposite direction.

Abstract: ABSTRACT OF THE DISCLOSURE A jacking assembly for moving a load, in steps, axially of a pipe comprises two pawl boxes having lateral platens and which are mounted at axially spaced positions on the pipe.  The pawls of the boxes slope towards the pipe and exert a grip on it which allows relative movement between the boxes and the pipe to occur in one direction only. In-flatable hoses connected to a low pressure water supply are sandwiched between the platens and exert a thrust, when dilated, which increases non-linearly with water pressure, to move whichever of the pawl boxes is carrying the load. This movement, which provides the working stroke, is followed by a recovery stroke during which the pawl box not carrying the load is moved up to the other pawl box under the action of springs or a second inflatable hose. The assembly is able to lift a heavy load with a low pressure water supply and has no moving seals.  Its operation in parallel with other such assemblies is also described for house building and slip forming purposes.
