Patent SE-8103451-L (SE)
Inventor: PERSSON A
IPC: E21B10/16
Filed: 1981-06-02
Abstract: A boring head with bearing brackets for cutting cylinders in pairs, has at least a first and a second set of cutting cylinders. The cutting cylinders have a number of rows of cutting elements formed e.g. by hard metal inserts which extend in rows around the circumference of the cylinders, and are offset axially to each other. The cutting cylinders of each set have the same number of rows of cutting elements, so that the number of rows on a first cylinder of a first set is at least as large as the number of rows on the second cutting cylinder of the second set. The pairs of bearing brackets are arranged one on each side of the axis of rotation of the cutting head and at the same distance from it. Each cutting cylinder of the first set can be replaced by any cutting cylinder of the second set. To alter the pitch circles along which the cutting elements engage with the rock, the first cutting cylinder in a first bearing bracket of a pair of brackets is replaced by the second cutting cylinder. At least one row of the cutting elements of the second cutting cylinder engages along a first circle which has the same radius as that of the circle along which a row of cutting elements in a third cutting cylinder of the second set moves when these are mounted in the second bearing in the one pair of brackets. It provides a boring head on which a process can be carried out for altering the pitch of the rows of cutting elements. The process is partic. of value in lift boring by means of a pilot hole between a lower and a higher level in a mine. The objective is to achieve the highest possible boring speed through rocks of different hardnesses by increasing the pitch of the rows of cutting elements in softer rock.

Abstract: The invention relates to the welding and deburring of chain links prebent in the form of a C and joined to form a chain, the process taking place in a single pass of the chain through a welding and deburring station. The chain links each belong alternately to one of two groups. The welding or deburring of one link of one group of links is performed simultaneously with the deburring or welding of a link of the other group. A system for the manufacture of a chain is equipped with a welding station (1) and a deburring station (6), which are set up opposite one another. A vertical axle is mounted in the centre between the stations, about which axle two horizontal arms (10, 11) can be pivoted. The two arms are each equipped with a device for clamping (29, 30) and positioning (25, 26, 27, 28, 49, 56) the chain link (58, 60) to be processed of the corresponding group and with a device (33, 34) for the stepwise advance of the chain. By means of the pivoting of the arms, the links to be processed are fed alternately to the welding station and the deburring station. <IMAGE>

Abstract: A centrifuge drum with a beveled-plate insert consists of individual plates held apart by spacing strips. The plates are mounted on a distributor foot. The bottom of the distributor foot has channels through which the liquid to be centrifuged is conducted into the separation space. There are ribs in the separation space. Between the ribs are lifting channels into which the channels in the distributor foot empty. The lifting channels are formed by the ribs and are positioned behind the spacing strips in the direction in which the drum rotates. The layout of the lifting channels prevents the liquid flowing into the plate insert from mixing with the solid particles that have been centrifuged out and are sliding out of the insert.

Abstract: The roller blind consists of a narrow tube, on which the blind material can be wrapped, which is fitted in two identical holders.  A sleeve whose hole at the outer end is circular and at the inner end   square, is pressed into the roller blind tube ends and fitted to a tube shaped spring from the holder with the same outer diameter as the sleeve hole's inner diameter. Rolling the blind up and down is effected by a ball chain meshed with a chain wheel set in between the legs of in the U-shaped holder, and the chain wheel's rotation is guided by a pin which sticks out into the sleeve. The ball chain's ends are joined together with a lock (49), which simultaneously acts as a stop for the blind's up and down motion; the lock can also be fitted as a stop for any desired position of the chain.  The lock consists of a slotted plastic sphere and the slot is fitted with an opening (49) to pull in and lock a ball on the chain into a recess (48). This recess is asymmetrically placed in the lock to give one half ball spacing difference for the stop, depending on how the lock is used.<IMAGE>

Abstract: To brake a sabot accelerated in a launcher of a recoiless rifle tube a mandrel shaped braking sleeve is disposed in the tube and an intermediate space is provided between a tapered surface of the mandrel and the tube into which the material of the front edge of the sabot expanded. In this way when the sabot is accelerated against the mandrel, its front edge slides along the tapered surface, radially outwardly into the intermediate space. This functions to deform and positively stop the movement of the sabot before it leaves the tube.

Abstract: A method wherein two light fluxes I1 and I2, spectrally encoded by interspersing or alternating line frequency spectra, are transmitted through an optical fiber from a transducer to an evaluation unit which generates an indication signal in relation to the ratio of the optical power of the two light fluxes. Both light fluxes I1 and I2 are generated with distinctly different narrow-bandline structures of the spectral distribution of their optical powers with the spectral separation of adjacent lines of the two line fluxes being greater than the linewidth of these lines. The optical power of the spectrally interposed light fluxes I1 and I2 are measured individually after spectral separation by filters which are selected to the specific distribution of the light fluxes I1 and I2.

Abstract: The clamping of the plate group (5) by the pressure spring (16) causes the movable part (4) of the chair to be locked in a specific position. A tension bolt (10) acts against the effect of the pressure spring to change the union from the clamped position to one where is is free. The union has three counterpieces, of which two (11,17) are fixed to the tension bolt. The third (15) is movably located in the housing (2) and displaceable relatively to the tension bolt. A second pressure spring (13) is fitted between the plates and one of the counterpieces (11) on the tension bolt to impart a specific residual clamping characteristic to the union in the freed position.

Abstract: The invention relates to a device for maintaining a constant supply quantity, preferably for pressure-dependent installations, by means of which device freely selectable throughput quantities per time unit can be set and the pressure changes which occur can be kept constant in a flow installation which is operated with an impeller pump with a specific throughput quantity per time unit, independently of self-induced pressure behaviour. This is achieved in that, in the pipe between the installation and a pump operated by an inductive motor, a pressure-independent quantity meter is arranged, which is electrically connected via a transmitter and a controller to a rotary-current frequency inverter which adjusts the rotational speed of the induction motor by changing the frequency as a function of the quantity delivered by the pump.

Abstract: The present invention relates to artificial onlay tooth crowns or inlays composed of a prefabricated core designed for preparations for onlay tooth crowns or inlays in natural teeth. The core is preferably fabricated from a high strength densely sintered ceramic material by copy milling from a negative reproduction from the prepared cavity to a compacted body or a presintered ceramic material. During the copy milling the sintering shrinkage is considered by enlargement of the copy milled compacted body or the presintered body corresponding to the sintering shrinkage. The onlay tooth crowns and inlays are given the final shape by shaping the surfaces outside the cavity of the compacted or the presintered body. After the final sintering the external surface can be shaped before a veneer material is attached to the external surface of the core by e.g. firing of dental porcelain. To manufacture onlay tooth crowns or an inlay according to the method of the invention decreases essentially the manufacturing time for onlay tooth crowns and inlays and at the same time the strength and the accuracy to shape increase.
