Abstract: Bone-containing animal material, such as slaughterhouse waste which has been scoured and dewatered by pressing, is separated into a bone-containing phase and a meat protein-containing phase by stirring the material with water after comminution to form a suspension (2) which is subjected to a separation in a hydrocyclone (8). The suspension is hereby separated into a bone-containing phase leaving the cyclone through its bottom nozzle, and into a meat protein-containing phase leaving the cyclone through its vortex detector and being processed into a protein product in a manner known per se.In the phase rich in meat protein at least about 70 weight-% of the dry matter is protein, whereas the bone-containing phase has a protein-content in the dry matter of less than 40 weight-%, including the ossein contained in the bones.

Abstract: A boiler tube gripper including a pair of pivotally connected members each of which is generally hook-shaped and provided with a generally semi-cylindrical inner surface to form a cylindrical opening when the pivotal members are pivoted to a closed position in encircling relation to a boiler tube or pipe with a lift element connected to one of the pivotal members at the periphery thereof to tilt the closed gripper which causes the diametrically opposed upper and lower edges of the closed gripper to engage the adjacent and remote surfaces of a boiler tube or pipe being gripped while being lifted and handled. The free ends of the pivotal members have a pin securing them in closed position with the pin being tethered to retain it in accessible position with the tether also serving to effectively release the pivotal members by pivoting one of the members toward open position.

Abstract: An open ended, flat spiral belt is joined at its ends on a roll to form an endless cover. A spiral belt is fitted with a zipper assist in the seam area to facilitate the joining of the spiral belt on the roll. One part of the zipper assist is removably attached to one end of the spiral belt with the other part of the zipper assist being removably attached to the other end of the spiral belt. When the two sections of the zipper assist are zipped together, they pull the two ends of the spiral belt together, allowing for interdigitation of the spiral loops of the spiral belt, which then forms a channel for the introduction of a seam wire. Once the spiral belt is seamed on the roll, the zipper assist is removed and the roll is set in slow motion at about ten revolutions per minute. The entire fabric is subjected to application of heat from a hot air gun to set the spiral belt, now in the form of a spiral shrink sleeve.

In order to obtain a multifunctional bag which can be easily and economically manufactured and readily recycled, the edge portion of one side wall protrudes beyond the edge portion of the other side wall, the protruding edge portion having a slit-like cut so that the protruding edge portion can be folded over the opposite side of the bag.

Abstract: A suspension system for a vehicle has cylinder devices in which suspension characteristics are changed by controlling fluid supply/discharge to/from the cylinder devices. The fluid pressure in the cylinder devices is sensed, and warping of the vehicle body is computed based on the sensed pressures. Then the fluid supply/discharge to/from the cylinder devices is controlled so as to suppress the warping of the vehicle body by a warp control unit. The warp control unit is provided so as to change the ratio of the fluid supply/discharge to/from the cylinder devices of the front wheels to the fluid supply/discharge to/from the cylinder devices of the rear wheels.

Abstract: A dispensing hopper fastened in a paper roll holder at the bottom for dispensing a paper roll, the improvement comprising a hopper body having a rotary seat revolvably secured thereto at the bottom to hold an oscillating member permitting it to oscillate on an axle disposed in radial direction through said rotary seat, wherein said oscillating member has an opening vertically through the center thereof which is consisted of two opposed tapered holes with a small hole connected therebetween, and two V-shaped retaining notches on the top edge thereof at two opposite locations at right angles to said axle. The leading end of the crepe paper of the paper roll is inserted through the tapered hole on the hopper body and lead out of the opening on the oscillating member. Pulling the crepe paper from the paper roll causes the oscillating member to oscillate to a matched angle permitting the crepe paper to be firmly retained in either V-shaped retaining notch for easy splitting.

Abstract: A multi-stage reactor-separator for the fermentative production of volatile inhibitory products from non-volatile substrate includes a stirred tank reactor and a packed or tray-type gas-liquid contacting column separator. Each reactor and separator form a stage and a plurality of stages may be stacked into a tower, or otherwise placed to operate consecutively, forming a reactor-separator in which stages having gas flowing cocurrent to the liquid flow in the separator portion form an enriching section, and stages having gas flowing countercurrent to the liquid flow in the separator portion form a stripping section. In a method of using the reactor-separator, a volatile fermentation product is produced and simultaneously separated into a gas phase.

Abstract: A magneto-optical storage medium and overwrite system comprises a first magnetic layer (reading/writing layer) (3), a second magnetic layer (auxiliary layer) (5) and a third magnetic layer (initializing layer) (7), each of which is a rare earth-transition metal alloy, and interface layers (4,6) for isolating magnetic exchange interaction between the magnetic layers, respectively. The second magnetic layer is initialized by the magnetization of the third magnetic layer (7) at room temperature. The first magnetic layer and/or the second magnetic layer is heated by a laser beam (P1) for demagnetization and remagnetization. The demagnetized portion of the second magnetic layer is remagnetized to the opposite direction by the demagnetizing field from the periphery. The demagnetized portion of the first magnetic layer is remagnetized to the same direction of the second magnetic layer.

Abstract: Two tape decks are connected to a player that plays back a recording medium. The reproduced sound is recorded on two magnetic tapes by the tape decks operating in parallel. During the recording, one of the decks stops earlier than the other because of difference in tape length and issues a tape-end signal. In response to the tape-end signal, the player is controlled to search for and reach the last recorded piece of music while the tape decks are rewound, paused or otherwise controlled singly or in combination in a suitable time sequence. This makes it possible to edit the tapes of different lengths during continuous recording without leaving blank periods on either tape.

Abstract: A control system for an engine with a turbo supercharger includes a first switching device for switching an introduction of intake gas to the engine in accordance with engine speed between a first intake condition, in which a charging efficiency of the intake gas is improved in a lower engine speed condition, and a second intake condition, in which the charging efficiency of the intake gas is improved in a higher engine speed condition. The control system also includes a second switching device for switching a maximum supercharging pressure of the turbo supercharger from a lower pressure to a higher pressure in response to a switching operation between the first intake condition and the second intake condition. An improved charging efficiency of the intake gas can be obtained in a broader range of the engine speeds reducing the maximum supercharging pressure of the intake gas, thereby preventing knocking of the engine.

Abstract: A cross coil-shaped indicating instrument includes a cross coil structure in which two coils are wound around a coil bobbin at right angles to each other. The coil structure is electrically charged in correspondence to the amount measured so as to form a composite magnet. A magnet rotor is disposed inside the cross coil structure. The magnet rotor has a center rotary shaft rotatable at a predetermined angle in correspondence to the composite magnetic field. A pointer is fixed to the end of the rotary shaft. In order to press the pointer into an appropriate position with respect to the rotary shaft, a pressure recess is formed in the coil bobbin so that a rod-like fixture can be inserted into the recess, and a stopper projects inside the pressure recess to press against the magnet rotor when the fixture is inserted. The stopper makes the magnet rotor stationary. While the rotary shaft remains stationary, the pointer can be fixed to an predetermined indicating position.
