Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for controlling the traveling speed of a motor vehicle with an electric control unit acted upon by a speed dependent signal, which unit compares the actual traveling speed with a predetermined desired traveling speed, and upon a deviation transmits a signal, which is dependent on the size of the deviation, to a control stage.  The control stage comprises a pnematic actuator which acts on an element, preferably a throttle valve, which influences the ratio of a fuel-air mixture fed to the motor of the vehicle, as well as two electromagnetically actuatable valves coordinated to the actuator, the valves enabling the actuator to be admitted with reduced- and above atmospheric- pressure, respectively, or normal pressure, respectively.  The control stage includes an electromagnetic system having an excitation coil and an armature cooperating therewith.  The armature is pivotally mounted for smooth pivoting from a rest position, in which position both of the two valves are closed, against the force of a spring, which force is dependent on the stroke of the actuator, into operating positions, respectively, in which positions one of the two valves is opened and the other valve is closed.

Abstract: DRIVE TRAIN AND TRANSMISSION    FOR FORAGE HARVESTER            ABSTRACT OF THE DISCLOSURE A belt transmission has a clutch that keeps both belts moving in the same direction when the transmission is in the forward mode and slackens only one of the belts dur-ing the usually brief interval that the transmission is placed in its reverse mode with the other belt moving in the reverse direction.  Both belts share a common actuat-ing lever having a lost motion coupling with one of the belts so that the lever can be placed in a neutral position in which neither of the belts is driven, even though power continues to be delivered to the transmission.  The drive train that supplies such power accomplishes a substan-tially right-angle drive from the swingable tongue of the machine without a gearbox by connecting a number of uni-versal joints in a series that  cuts across the  corner between the swingable tongue and the main driven shaft of the transmission.

Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus for improved recovery of heat from combustion gases in the convection section of a furnace by improved radiant heat transfer.  Thin strips of selected metals are arrayed and supported on the fluid carrying pipes in the furnace, in such a way that interference to the vertical flow of combustion gases is held to a minimum.  The metal strips are heated by flow parallel to their surfaces of the combustion gases.  Heat is radiated from the metal strips to the pipes with a consequent increase of heat transfer to the fluid within the pipes.

Abstract: ABSTRACT OF THE DISCLOSURE           A flying shear is disclosed in which a shear carriage is arranged to be driven along the pass line of a moving strip, between a pair of spaced shear  platens.  The carriage is con-structed for telescoping movement and mounts a pair of cooper-ating carriage plates.  The platen member are stationary, but are arranged to have relative closing and opening movement, in order to telescopically compress the shear carriage at desired times, to effect a shearing operation.           A novel form of support is provided for the shear car-riage, enabling the carriage normally to be supported from the platen structure by means of antifriction rollers, which accom-modate rapid acceleration and high speed movement of the carriage. At the instant when the shearing operating is to occur, however, the closing movement of the platens serves to effectively disable or retract the antifriction roller support for the carriage and cause the carriage to be supported by relatively broad area, elongated, sliding friction bearing surfaces.  The arrangement is such that the advantages of the antifriction support are re-alized for raped acceleration and high speed travel of the car-riage, while at the same time the heavy shock loading of the shearing operation itself is effectively isolated from the anti-friction elements.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification describes heat-stable pressure-moulded composite explosives which comprise at least one crystalline explosive having a high rate of detonation and, as a synthetic binder therefor, a cross-linked silicone resin.          These composite explosives are produced by coating the crystalline explosive in the presence of water with a thermosetting polysiloxane prepolymer, then drying and cross-linking the moulding powder obtained, and finally cold-compressing the cross-linked moulding powder to form a shaped composite explosive.         These explosives have exceptional mechanical strength at elevated temperatures which enables them to be used in all types of explosive charge.  The process used provides increased safety and results in a lower cost price.

Abstract: ABSTRACT OF THE DISCLOSURE           In a feedlot operation wherein ruminant animals, such as cattle or sheep, are fed ad libitum a high-energy ration or feed, lactic acidosis is greatly reduced or eliminated and weight gain and feed conversion are increased by administering to the animal the micororganism Peptococcus asaccharolyticus upon introduction of the animal to the feedlot.  The microorganism is conveniently administered to the animal, either by direct injection or introduction into the rumen via a needle or stomach tube or in admixture with the reed or ration.  The microorganism is also useful in the treatment of cattle (calves) and sheep ill with lactic acidosis.  Deposit of the microorganism of interest in this invention, Peptococcus asaccharolyticus, has been made with the American Type Culture Collection, 1230 Park Lawn Drive, Rockville, Maryland 20552, U.S.A., and the deposited micro-organism has been assigned ATTC No. 31229.

Abstract: ABSTRACT OF THE DISCLOSURE         A suspended mass is shaped by melting all of a selected portion of the mass and applying acoustic energy in varying amounts to different portions of the mass.  In one technique for forming an optical waveguide slug, a mass of oval section is suspended and only a portion along the middle of the cross-section is heated to a largely fluid consistency.  Acoustic energy is applied to oppo-site edges of the oval mass to press the unheated opposite edge portions together so as to form bulges at the middle of the mass.          In another technique for forming a ribbon of silicon for construc-ting solar cells, a cylindrical thread of silicon is drawn from a molten mass of silicon, and acoustic energy is applied to opposite sides of the molten thread to flatten it into a ribbon.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure describes a method of removing hydrogen sulfide from gases, particularly coke-oven gases and for obtain-ing elemental sulfur.  Hydrogen sulfide is washed out of the gases in a scrubbing unit which uses a scrubbing solution and is expelled from the scrubbing solution by adding water vapor thereto.  The resulting vapours, consisting mainly of hydrogen sulfide are fed to a Claus plant in which most of the hydrogen sulfide is converted into elemental sulfur.  The gases leaving the Claus plant are hydrogenated to form hydrogenated waste gases.  The latter are cooled to form a condensate and are added to the gas to be purified before reaching the hydrogen sulfide scrubbing unit.  This method is less expensive than known methods and provides a thorough environmental protection.

Abstract: ABSTRACT           A power tong includes a frame and a pipe-gripping mechanism associated with a throat at one end of the frame.         Power is transmitted to the pipe-gripping mechanism from a power unit through a drive train.  The pipe-gripping mechanism cooper-ates with the throat to receive a pipe section to be rotated and includes a partial ring rotatably mounted within the frame and having an opening which may be aligned with the throat.  The ring may be rotated in either direction by the power unit.  Mounted on the tong is a die carrier which is rotatable relative to the ring.          Die members are mounted on the die carrier and include dies positioned to grip the external surface of the pipe section.  The die members are arranged to cooperate with cam surfaces on the ring so that, when the ring is rotated relative to the die carrier, the dies are moved rectilinearly into engagement with the pipe section.  After the movable dies have engaged the pipe section further relative movement between the ring and the die carrier is prevented and the pipe section is therefore rotated to make up or break apart the threaded joint of pipe.
