Abstract: A hanging picture gallery or album comprises a plurality of relatively large plastic sheets, each formed with a large number of pockets adapted to retain individual photographs. In the preferred embodiment, the pockets are formed on both sides of each sheet, and the plastic sheets are vertically retained on a special multiple hook support in turn adapted to hang from the top of a door. The number of plastic sheets is limited only by the size of the hooks on the special multiple hook support. Ten to fifty sheets may be accommodated on a special multiple hook support without unduly stressing a solid properly hung door. Each sheet may have twenty to fifty pockets for photographs on each side, all on one side viewable at the same time. In the preferred embodiment, the sheets are slightly less than 30? wide to conveniently be hung from the hooks on the back side of a closet door or bedroom door.

Abstract: A sheet handling system having a number of sheet processing modules (1-4) linked together to enable sleets to pass between them. Each sheet processing module (1-4) includes at least one sheet monitoring or handling component and a set of nodes (23, 32, 43, 62), each including a processor, wherein each sheet processing module is controlled by one or more nodes. A distributed control system is arranged logically into a number of subsystems, the functions of each subsystem being performed by one or more of the nodes. A communications network (24) links the nodes together to enable the nodes to operate in synchronism and to communicate with each other.

Abstract: A method and apparatus for measuring pulmonary blood flow in a subject by pulmonary exchange of oxygen and an inert gas with the blood using a divided respiratory system. One method of isolating two or more divisions of the respiratory system uses a multi-lumen cuffed endobronchial catheter. In one embodiment, a triple-lumen cuffed endobronchial catheter is provided. In another embodiment, gas mixtures are supplied to each lumen using a bag-in-a-box type ventilator for each breathing system for synchronizing the rate and pressure of mixed gas supplied to the lumens.

Abstract: A compensation device receives an inlet fluid flow and adjusts the pressure at an outlet so as to maintain a constant Reynolds number throughout the operating temperature range of the fluid. This is accomplished by a metering valve device in the nature of a fluted pin which becomes displaced in response to fluid temperature variations. This displacement varies the exposed cross-sectional area of a fluted end of the pin as it becomes seated to a greater or lesser extent in response to temperature variations. This results in corresponding changes in pressure between the inlet and outlet of the device while maintaining a constant Reynolds number. An additional embodiment includes an unfluted pin which becomes seated in a fluted bore located in a removable knurled knob. This allows one to insert various knurled knobs with fluted bores which have geometric configurations particularly adapted for particular fluids. Such a modular approach avoids the necessity of dismantling the device.

Abstract: New echiboline derivatives with opioid properties which are 6-hydroxy-9-methyl-echiboline derivatives having, in the 10-position, a hydrocarbon substituent of up to 4 carbon atoms--preferably a group R.CH.sub.2 -- (wherein R represents a hydrogen atom or a hydrocarbon group of up to 3 carbons) and especially a methyl, cyclopropyl-methyl or allyl group.These are made by dealkylating corresponding 6-alkoxy-9-methyl-10-substituted echibolines, thereby converting the 6-alkoxy group to a 6-hydroxy group, especially using boron tribromide as dealkylating reagent.Specific examples are 6-hydroxy-9,10-dimethyl-echiboline, 6-hydroxy-9-methyl-10-allyl-echiboline and 6-hydroxy-9-methyl-10-cyclopropylmethyl-echiboline.The compounds may be in free base or salt form, and be incorporated as active ingredient into pharmaceutical compositions.

Abstract: In wool scouring systems in which scouring liquor is continuously withdrawn from the scouring bowls for separation of solid contaminants and wool grease and then recycled to the bowls, improved separation of solids is achieved by adding a soluble silicate, and preferably also a polyelectrolyte to the liquor before solids separation. Silicate can advantageously replace soda as scouring agent. Improved operation can also be obtained by controlled flow down from the circulatory system, as at 27, and by passing the jet phase from a disc centrifuge 17 to a decanter centrifuge 15 for further separation of solids. Alternatively, the entire liquor circulation may be passed first to the disc centrifuge and only the jet phase to the decanter, the middle liquor phase being recycled.

Abstract: Thermoplastic yarn is texturized by the known method of forwarding it in a heated condition to a crimping zone at the entrance of a stuffer chamber (7) so as to form a plug (8) of crimped yarn within the chamber and withdrawing the yarn from the other end of the plug at a speed which is related to the input speed. The improvement comprises deriving signals from the speed of the yarn plug (8) in the stuffer chamber (7) by means of a sensing wheel (11) which drives a gapped monitoring disc (13). The disc (13) operates to intercept a beam of light from a source (14) which is directed on to a photo-sensor (15). The output of the photo-sensor is supplied to an electrical controller (36) which measures the time during which light is received for each gap in the disc (13) to provide a measure of the speed of the yarn plug.

Abstract: The invention relates to herringbone struts, in particular to such a strut made from a single piece of metal and having a cross-section of generally 'M'-shape in transverse cross-section with end flanges which are inclined at angles of greater than 90.degree. to the longitudinal axis of the strut so that in use the strut is inclined when it is secured between two joists.

Abstract: Elements for forming a frame such as a metal door frame having spring clips by which a head rail and side members are connected, and a spacer or tie bar by which the elements can be stabilized during erection of the frame in a door way.

Abstract: The invention relates to members for forming in use a complete guttering system which can be used for any slope of roof. There are two members, one a gutter-fascia member and the other a soffit member, and each member has a complementary part of a hinge or pivot so that when the two hinge or pivot parts are connected, a hinge or pivot is formed which allows relative rotation of the two members so that any roof pitch can be accommodated.

Abstract: A lintel for a double-skin wall including a first member secured to the inner skin and a second member secured to the outer skin and adapted to be disposed over an aperture or opening formed in said wall. The first member has a downwardly extending flange portion disposed within the cavity between the inner and outer skins and spaced a slight distance from the adjacent surface of the inner skin. The second member is secured to the outer skin, as by having a substantially horizontal flange disposed below a course of blocks or the like. The second member has a sloped plate secured to the inner edge of the horizontal flange and extending upwardly into and across the cavity. The sloped plate has an upwardly extending flange on the upper free edge thereof which extends into a recess defined between the inner skin and the downwardly projecting flange associated with the first member.
