Abstract: In a connecting device for a switch actuator and/or a lock for movable parts of a railway switch or crossing, including a rod assembly, in particular a sliding rod or a locking rod articulately connected with the movable part, the movable part or the rod assembly, in particular the switch tongue (2), is rigidly connected with a strap (4) engaging from behind a pin (5) connected with the rod assembly or the movable part for transmitting tensile forces. Between the rod assembly and the strap (4) or the movable part is arranged at least one elastic compression element, which is compressible by the rod assembly in the abutment position of the movable part on a rigid rail part, the strap (4) being displaceable out of abutment on the pin (5).

Abstract: The method for granulating liquid slag melts, in particular blast furnace slag, in which the melt (2) is ejected into a cooling chamber via a slag tundish (1) and in which fluid under pressure, in particular compressed gas, vapor or pressurized water, is injected in the direction of the slag exit (6) in order to eject said liquid slag, is characterized in that the pressure fluid jet discharges into a throttle pipe (3) which is immersed in the slag bath and whose lower edge is mounted so as to be adjustable in the height direction (4). The corresponding device comprises a lance (7) which is surrounded by a height-adjustable throttle pipe (3) whose lower edge (5) is immersed in the slag bath (2) contained in the tundish (1) and forms a throttling cross section between the slag exit (6) and the slag bath (2).

Abstract: A snow thrower of compact proportions is obtained by a single piece housing which supports an engine having a vertical output shaft extending within the housing. The housing also supports a horizontally disposed auger drive shaft. A belt drive connects the engine drive shaft and the auger drive shaft via a pair of idler pulleys, one disposed at an inclined angle and the other being mounted on an idler arm pivotally mounted within the housing. The belt and idler arm pass through an opening in the housing to achieve the belt drive connection. A control member is provided to move the idler arm to tension the belt for driving the auger drive shaft or to relax the belt to interrupt the belt drive connection. In the latter condition, the belt is braked while retaining light contact between the engine and auger drive pulleys.

Abstract: In a process for granulating and disintegrating molten slags, in particular blast furnace slags, with water, a compressed water jet is directed into the slag and the slag is ejected as the jacket of the compressed water jet. The device for carrying out the process comprises a slag vessel for molten slag including an outlet opening for the molten slag, wherein a lance opens into the axis of the slag outlet opening such that the molten slag is ejected by compressed water or vapor introduced through the lance.

Abstract: A dry shaver includes at least one shaving blade which is arranged in a pivotable head frame closed on its sides and which cooperates with cutters oscillating in the longitudinal direction of the shaving blades. The head frame is detachably connected with a base part which includes a cutter driving mechanism. The head frame is designed in two parts, wherein an outer head part carrying the shaving blade(s) is pivotally connected with a part of the head frame that is detachably fixed to the base part, the pivotal connection being about an approximately central pivot axis extending transverse to the oscillation direction of the cutters.

Abstract: Isotactic poly(glycidyl nitrate) useful in solid propellants is produced by polymerizing chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate. Chiral (R) glycidyl nitrate or its enantiomer is prepared by sequential treatment of chiral (S) glycidyl tosylate or its enantiomer with nitric acid and sodium hydroxide. Chiral (S) glycidyl tosylate or its enantiomer, (R) glycidyl tosylate, can be produced by Sharpless epoxidation of allyl alcohol or by direct tosylation or commercially available chiral glycidol. Likewise, chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate, can be prepared directly via nitration of (S) or (R) glycidol, respectively.

Abstract: Propellant compositions have an elastomeric binder formed by curing a hydroxyl-terminated polyether or polyester prepolymer with cis-,cis-1,3,5-tri(isocyanatomethyl) cyclohexane. The propellant compositions also include high-energy particulates and high-energy plasticizers. The use of cis-cis-1,3,5-tri(isocyanatomethyl)cyclohexane increases the energy of the propellant per binder weight and in several cases substantially improves the mechanical characteristics of the propellant composition.

Abstract: This invention is for new compounds, namely, diethanolammoniummethylcubane nitrates, a composition of diethanolammonium methylcubyl nitrates - hydroxylammonium nitrate (HAN) solutions and their method of use as aqueous liquid gun propellant ingredients.

Abstract: The invention is a propellant rocket motor case designed to meet insensitive munitions requirements comprising a propellant surrounded by a case having slots therein, and a wrapping around the case, the wrapping comprising a load bearing material which can withstand the hoop load on the case during normal firing of said rocket, the material also having the characteristic of losing strength or melting at undesired temperatures above normal storage temperatures, but below the autoignition temperature of said propellant, so that during undesired high storage temperatures the propellant will exhaust any subsequently generated gases, due to any subsequent propellant burning, by venting through said slots thereby avoiding any explosion or undesired operative one-way thrust.
