Abstract: 1,083,756. Dynamometers; linear dimension gauges. WIRTH, GALLO & CO. Jan. 20, 1966, No. 2672/66. Headings G1M and G1W. A dynamometer or extensometer comprising at least two arms or discs which are rotatable relatively to one another about a common axis so that relative rotational movement of the two arms or discs serves as a measure of the force or extension applied, is characterized by the fact that one or more rods obliquely mounted with regard to the common axis join the ends of the arms or the edges of the discs, to which they are fixed by means of elastic or ball joints. The first arm or disc may be fixed to a shaft and the second mounted for rotation and axial displacement thereon with the rod coupled to the arms or discs by ball joints, Fig. 3 (not shown). Where two discs are used they may be coupled by a plurality of rods which may be formed at their ends with portions of reduced diameter sufficiently elastic to bend when a force or extension is applied Fig. 5 (not shown). A third central disc may be connected to the end discs by two sets by rods arranged with opposite obliquity with respect to the axis, Fig. 6 (not shown).

Title: Pharmaceutical preparations containing choline ester salts
Inventor: NUMEROF PUAL
IPC: A61K31/16
Filed: 1963-01-23
Abstract: Stable pharmaceutical compositions containing a salt of an ester of choline or a homologue thereof are prepared by dissolving a non-toxic salt of said ester in a parentally acceptable, water-miscible organic solvent and adjusting the pH of the resulting solution to 2.8 to 3.5 by adding to the solution a physiologically acceptable organic or inorganic acid or an acidic ion exchange resin.  Suitable salts are derived from bis-esters of choline or its homologues with dibasic acids, e.g. malonic, succinic, glutaric, adipic, pimelic, maleic and fumaric acids.  The anions of the salts may be derived from acids such as, sulphuric, nitric, phosphoric, hydriodic, hydrobromic, hydrochloric, citric, acetic and tartaric acids.  Solvents specified are ethanol, propylene glycol, glycerine, glycerine formal, N, N-dimethylacetamide, dimethyl sulphoxide and dioxane. Acidifying agents mentioned are nitric, phosphoric, hydrochloric, fumaric, adipic, succinic and citric acids, and Dowex 50 W and Amberlite IRC-50 ion exchange resins ("Dowex" and "Amberlite" are Registered Trade Marks).

Filed: 1939-01-21
Abstract: 509,293. Heating food by passage of current ; switches. SALINSKI, B. Jan. 21, J939, No, 2190. [Class 39 (iii)] [Also in Group XXXVII] In apparatus for heating solid foodstuffs, particularly sausages, by passing electric current directly through them, the food to be heated is placed in an open water-bath and between electrodes arranged at its ends, one of which 14 is fixed in the container 13, while the other 23 is movable, and is displaceable under the action of the expansion of the food when it becomes heated. The movable electrode 23 is carried by a rod 21 which is longitudinally guided in the frame 11. The rod 21 is located in the range of movement of a gripping-lever 25, which can be moved by a hand lever 28 into the gripping-position, the hand lever being kept locked by the pawl 31 in the said position. The lever 25 is adjustable to a plurality of heights by means of an eccentric 34 to enable the travel of the electrode 23 to be adjusted. The detent 31 is pivotally mounted at 30 and extends with a tappet 33 at a distance above the lever 25. When the food becomes hot, it raises the electrode 23 and the rod 21, and the latter takes with it the lever 25 which strikes against the tappet 33 and pushes the detent 31 away from the roller 32 so that the lever 28 is moved into the left-hand position under the action of the spring 44. At the same time the switch 18 is put into the released position by the hand lever 28 and the heating-current is switched off.

Abstract: 1,151,561. Admission pipes; valves. H. WESLAKE. April 22, 1966 [Jan.22, 1965], No.2988/65. Heading F1B. Each cylinder of an I. C. engine is provided with two valve-controlled inlet ports, which are both fed with mixture from a single carburetter, and additional valve means are provided for successively opening or successively closing two inlet passages, which passages respectively convey mixture to the two inlet ports of each cylinder. As shown in Fig. 12, the left hand group of three cylinders is fed from carburetter 53 through manifold 47/50, the right hand group being fed from carburetter 54 through manifold 48/51. Manifold branches 47 and 48 are interconnected at 60, are controlled by manually operated, linked throttle valves 55, 57, and feed one set of inlet ports 13. Branches 50, 51, also inter-connected, feed the other set of inlet ports 14 and are controlled by linked valves 56, 58, which are operated by a pneumatic motor 63, responsive to the suction in inter-connecting pipe 60. Alternatively, the motor 63 may be responsive to engine speed. In either case, valves 56, 58 open after and close before valves 55, 57. In an alternative arrangement, Figs. 1-3 (not shown), an elongated, ported slide valve is movable from one extreme position (in which both sets of inlet passages are open) to successively and progressively close one and then both sets of passages. The slide valve may be controlled in response to engine suction or speed or the position of the engine throttle valve. Each cylinder may be provided with one or two exhaust ports. Swirl of the gases in the engine combustion chambers may be promoted by arcuate deflecting members (not shown) on the heads of the inlet valves or by projections formed on the surface of the combustion chamber, Fig. 9 (not shown) or in the valve cavities, over which projections the gases sweep.
