Abstract: METHOD AND APPARATUS FOR CHANGING FILTERS IN NUCLEAR POWER STATIONS                ABSTRACT OF THE DISCLOSURE          A remote control apparatus for removing from one of a number of filter pits, and loading for protective storage in a disposal drum, radioactive filters used in nuclear power generating stations, and for replacing spent filters.  The apparatus includes a transportable base adapted to be placed adjacent the respective filter pit and a hoist mechanism mounted on the base.  The hoist mechanism includes a vertical tower or mast mounted on the base, a generally horizontal boom mounted on and extending outwardly from the top of the mast, a grab mechanism for engaging various specially adapted articles, including spent filters to be removed and new filters for replacement, means for operating the grab mecha-nism from a remote location, a lift mechanism for supporting the grab mechanism from the outer end of the boom and for raising and lowering it in a vertical path, and means for operating the lift mechanism from the remote location.  A drum turret is mounted on the base for rotary movement about a vertical axis spaced from the vertical path, to and from a filter receiving position wherein a storage drum carried thereby is placed in the aforesaid vertical path to receive a removed filter to be lowered therein by the lift mechanism. The drum turret is adapted to be operated from a remote loca-tion.  A second turret is mounted on the mast intermediate the base and the boom for rotary movement about the aforesaid vertical axis and has preferably two radially extending plat-forms adapted to be positioned selectively in alignment with the vertical path of travel to receive from or locate for the grab means a spent or new filter or other article to be sup-ported by the second turret.  The second turret is also adapted to be operated from a remote shielded location.

Abstract: Abstract A process for the synthesis of compounds which are known intermediates for the pyridyloxyphenoxy herbicides as well as intermediates used in the process. Propionaldehyde and an acrylic compound, two readily available starting materials, are reacted to form a 2-formylpentanoic compound which is cyclized to a dihydro pyridone which is then oxidized to the 2-hydroxy pyridine. The hydroxypyridine may be halogenated to a 2-halopyridine.

Abstract: ABSTRACT     An expanding anchor assembly for insertion into a bore  in  ground.   The assembly comprises a one-piece expanding sleeve divided by longitudinal slits into seg-ments.   A conical expander engages the bore internal end of the expanding sleeve for expanding same.   A bolt is also provided and has  a bore  internal end engaging the expander and a bore external end.   A tightening member is  provided on  the bore external end of the bolt.   A spacer bushing  extends  around the bolt and  engages  a sleeve-like tube section.   A washer is provided beneath the  tightening  means  for clamping  a workpiece  against the surface of the ground.  The sleeve-like tube section is a soft steel tube section having a pronounced plastic flow limit.   The tube section has a predetermined wall thickness such that, upon application of a setting force specific for the bolt anchor, compression stresses will prevail in the tube section which equal the stresses pre-vailing  in  the material  of  the  tube  section when  the plastic flow limit is reached.   The tube section has a hardened thin surface layer breaking in a brittle fashion when the sleeve-like tube deforms axially after attaining the anchor specific setting force.

Abstract: A B S T R A C T  TITLE: A SUPPORT BRACKET FOR A VENETIAN BLIND HEADRAIL       A support bracket for  a venetian blind headrail which is in the form of an open sided box structure including a top (14), bottom (10) and a side (16) and/or rear wall (12) and a separate front wall (18, 20) which is pivotal about a vertical axis with respect to the top and bottom walls, and which includes top and bottom flanges (22).  This pivoting is effected by a pivotal connection including a guide aperture (30) formed preferably in the top and bottom flanges, the aperture providing two guide surfaces (32, 34) angled with respect to one another, a hinge element (28) in the top and bottom walls engaging in each aperture. whereby the front wall can be pivoted between an open position and a closed position transverse to the open position.  A latch (38, 40) is provided on the top and bottom flanges and on the top and bottom walls, the latch being spaced from the pivotal connection and prevents pivoting of the front wall away from the closed position.  Unlatching is effected by moving the front wall (18, 20), when in its closed position, away from the side wall (16) so that the hinge element moves on one guide surface (32) to the junction of the guide surface and then the front wall can be pivoted to its open position, the hinge element then moving along the other guide surface (34) during the pivoting motion.

Abstract: VERTICALLY INTEGRATED CMOS LOGIC GATE Abstract of the Disclosure A vertically integrated CMOS logic gate has spaced semiconductor layers with control gates located between the layers and insulated from them by gate oxide.  Transistors formed in one semiconductor layer are vertically aligned with transistors formed in the other semiconductor layer.  Pairs of vertically coincident transistors have common control gates and certain of the pairs have integral drain regions.  Transistors in one layer are series connected in an open loop configuration and transistors in the other layer are parallel connected in a closed loop configuration.  The logic gate function depends on voltages applied to the common control gates and to the open and closed loops.  By the vertical integration, a two-input NAND or NOR gate can be made using less area than that required for two simple MOS transistors.    -i-

Abstract: ABSTRACT      A knife for trimming wallpaper has two tapered body parts 8 and 9 between which is held a tipped cutting blade 5.  The body parts have external side faces which are flat around central recesses.  When the side face of a body part is in engagement with a flat surface 4, such as a wall, the tip of the blade is a predetermined distance from the plane of the flat surface.  When the end face of the body is brought into engagement with a surface transverse to the flat surface, such as an architrave 3, the knife can be drawn down in a stable manner to cut the wallpaper at the predetermined distance in a neat fashion.    The two parts of the body are identical and contain crossing inclined grooves to contain the blade so that it projects from a corner of the body.     Figure 2.
