Abstract: Compounds of formula I ##STR1## are described which are useful to inhibit the formation of serum cholesterol by virtue of their ability to inhibit .beta.-hydroxy-.beta.-methylglutaryl-CoA(HMG CoA), the rate-controlling substance in the synthesis of serum cholesterol.

Abstract: A paramagnetic metal species-containing diagnostic agent is disclosed which comprises a non-radioactive paramagnetic metal species and, as a carrier therefor, a physiologically tolerable, water-insoluble, hydroxyl group-containing, particulate macromolecular product consisting essentially of at least one polymeric or polymerized carbohydrate or polymerized sugar alcohol or derivative thereof.

Abstract: A high leakage reactance transformer especially for current limited control of gas discharge lamps and other electrical discharge loads has a core with three legs defining two magnetic loops. A first leg has an air gap with a fixed reluctance, a second leg is common to both loops and has a primary winding, and the third leg has a supply winding for connection to the discharge device as well as a control winding connected to a control circuit. The control winding has an adjustable load to vary the reluctance of the third leg and control the current limit of the supply winding. Linear and proportional control circuits are shown.

Abstract: A hand-fed data-card reader compatible with cards of different widths and having a selectively actuable perforator for conveying cards past a reader head and for selectively cancelling desired cards via the perforation thereof. Cards are conveyed via a belt/pulley drive train that is operably coupled to a spiked perforator that engages each card at a preset one of two pressures so as to selectively convey the card with or without embossing the surface in a chadless fashion and whereby cancellation is achieved. Data media of differing widths are accommodated via an adjustable, lower, spring loaded guide assembly.

Abstract: Tall oil pitch neutralized with calcium oxide to an acid number between 0 and 7 mg KOH per gram acts as an anti-rust or corrosion preventing agent. The agent may be used most conveniently in solution form. The agent is produced by neutralizing tall oil pitch with an acid number of 20-70 mg KOH per gram with a solution of calcium oxide at elevated temperature to the desired acid number between 0 and 7 mg KOH per gram. Application of this agent to a material normally subject to corrosion acts to prevent corrosion from occurring.

Abstract: In a method for compacting compactable soils by vibration while using a compacting apparatus comprising an elongate member having a vibrator mounted on one end thereof, and further having laterally projecting fins arranged along at least part of the length thereof, the elongate member is inserted to a given depth into soil to be compacted and there vibrated to densify and compact soil surrounding said elongate member while withdrawing the elongate member from a compacted location when the load required to lift the elongate member together with the vibrator from said location, while the member is vibrating, is at least equal to a previously established set-point value corresponding to a desired degree of compaction.

Abstract: In order to fix the position of two printed wiring connectors located on the same circuit board an attaching bar is used. This bar is laid over the connectors and is provided with positioning pins adapted to engage the attachment holes of the connectors. The bar is provided with mounting studs having mounting holes at some distance from the edge of the card so that corresponding holes in the card will not weaken the edge.

Abstract: A diagnostic agent for intravascular administration into blood vessels composed of radioactively labelled particles suspended in a physiologically acceptable aqueous liquid, said particles having a size so selected that they clog fine blood vessels having a diameter within the range 5 - 300 .mu.m, said particles consisting of a three-dimensional, water-insoluble, hydrophilic, swellable, cross-linked network of polysaccharide substances, and the method of using this diagnostic agent.

Abstract: The present invention relates to an agent for intravascular administration, said agent consisting of a suspension of minute polysaccharide particles having a size such that subsequent to being administered intravascularly, they block the finer blood vessels of the body and a diagnostic agent.

Abstract: A tactile feel device which provides a characteristic resistance to movement, and breakaway feel to signal the operator that movement and accompanying function, such as switching, has been accomplished. Resistance to movement is provided by spring biasing means for the initial stroke of the device, by spring biasing means plus magnetic force at the end of the initial stroke, and by spring biasing means only, after magnetic breakaway at the end of the initial stroke, to provide a characteristic breakaway feel. The device is shown and described in connection with a light pen which generates a signal when pressed against a cathode-ray-tube faceplate. The characteristic breakaway feel signals the operator that the tip or probe of the pen has been sufficiently pressed against the cathode-ray-tube to generate the appropriate signal in the light pen.

Abstract: A pharmaceutical product containing amino groups, which product:A. is comprised of residues of one or more diamines of the general formulaH.sub.2 N.CH.sub.2. phenylene.CH.sub.2.NH.sub.2 (I)which residues are interconnected by bridges between the residues to form a three-dimensional network, the bridges being bound to nitrogen atoms in the residues (I) and comprise straight or branched aliphatic, saturated hydrocarbon chains substituted with one or more hydroxyl groups and containing 3-30 carbon atoms, preferably 3-16 carbon atoms and which are optionally broken by one or more oxygen atoms, the amino groups being present in a free form or in the form of (the cation portion of) a non-toxic salt, andB. is insoluble in water or other solvents, but capable of swelling in water to gel form, 1 g of the dry product in the form of an HCl salt in the presence of water swelling to at least 5 ml and to at most 50 ml, preferably to at least 5 ml and to at most 25 ml, andC.
