Abstract: "ROCK OR STUMP REMOVER ASSEMBLY" ABSTRACT OF THE DISCLOSURE          A rock or stump remover includes a frame with a pair of hooks cut from heavy-duty plate depending there-from in spaced and parallel relationship and pivotally attached to the frame and detachably held in the working position by shear bolts which shear and allow the hooks to pivot individually relative to the frame.  The frame is designed to be detachably connected to the three-point hitch at the rear of the tractor.  In contrast to exist-ing devices, the shear bolts yield individually at a pre-determined load thereby preventing damage not only to the assembly but also to the three-point hitch connection.

Abstract: 49,370 ABSTRACT OF THE DISCLOSURE High-intensity-discharge  lamp of  the  mercury-metal halide type efficiently illuminates objects with excellent color appearance.  The  arc  tube  filling com-prises the usual inert, ionizable starting gas and mercury in predetermined amount as required to provide a predeter-mined operating voltage drop between the lamp electrodes. The metal halide filling substantially comprises a prede-termined limited amount of thallous iodide,  a predeter-mined limited amount of stannous iodide and a predeter-mined  limited  amount  of  calcium iodide.  The  stannous iodide is used in such amount that it serves primarily to enhance the emission of the calcium iodide and the amount of stannous iodide is sufficiently limited to curtail the generation of the characteristic continuous tin emission. The calcium iodide is present in greater gram amount than the tin iodide so that the effects of the calcium iodide emission are predominant.  The resulting discharge has its emission concentrated in three selected wavelength por-tions of the visible spectrum, namely, blue violet which is due primarily to the calcium iodide emission,  green which is due to the thallium iodide emission,  and red which  is due  to the tin-iodide-enhanced calcium iodide emission.  The efficiency of the composite discharge is good and the color appearance of illuminated objects is excellent.

To produce the shaped brick, the mixture of binding agent, granular aggregate material and water, if necessary after a matur-ing, is shaped and subsequently, particularly in autoclaves, hard-ened, or under addition of reaction-prompting and boiling point elevating substances, such as sodium hydroxide, hardened at normal pressure, if necessary in a steam chamber; therewith the mining waste material is first ground to a grain band up to a maximum 15mm grain size with a finest grain portion under 0.2mm from 10 to 45% by weight, in particular having been obtained through milling or separation measures.  Through particular choice of granulation and density, the mining waste material can be adjusted to desired quality characteristics and the physical characteristics of the shaped brick varied, corresponding to utility.

A data signal receiver for a bi-phase modulated signal comprises a filter 1 feeding a sampling switch 2 which feeds a polarity detector 3 from which the decoded data is reproduced. The phase of the sampling switch 2 is controlled by the output 6-Q of a ? 2 frequency divider 6 which is driven by a phase-locked loop 5 which in turn is driven by a zero-crossing detector 4 at twice the bit frequency.  A monitoring arrangement 8 has sampling switches 10 and 11 driven by outputs 6-Q and 6-Q of the frequency divider 6. The data signal applied through a full-wave rectifier 9, is sampled at instants to and t1, at twice the bit frequency.  The outputs of the sample switches 10 and 11 are fed to minimum voltage detectors 12 and 13 which detect the minimum value of the samples over a number of cycles of the input and apply this value to the inputs of a comparator 14.  If the output of detector 12 is more positive than that of detector 13 the receiver is correctly synchronised but if the output of detector  13 becomes more positive than that of the detector 12 the output of the comparator changes state and causes a pulse to be applied to input 6-1 of the divider to change the phase of the divider output 6-Q.

Abstract: Attorneys Docket No. 6957 CAN          INVENTOR:   HANS SIGG          INVENTION:  CLUTCH ARRANGEMENT FOR A MARINE VESSEL DRIVE               ABSTRACT OF THE DISCLOSURE        A normally driving or drive shaft is connected with a drive-side coupling half of a synchronizing tooth clutch as well as with a primary part of a fluid coupling, whereas a normally driven shaft is connected with a clutch half of the tooth clutch arranged at the power take-off side as well as with a secondary part of the fluid coupling.  The tooth clutch has a clutch star which is axially displaceably guided by means of a first straight tooth system at the drive-side clutch half due to continuous meshing of the teeth, and can be engageable with a second straight tooth system provided at the power take-off side clutch half.          Threadably connected with the second clutch half is a screw socket which is connected by a pawl blocking device with the clutch  star  and  is  conjointly  axially  displaceable therewith.   The pawl blocking device engages and brings about a screw-like relative movement of the screw socket in relation to the power take-off side clutch half and which causes an engagement of the clutch star, when the rotational speed of  the drive-side clutch half,  during the normal forward rotational direction, is in the process of falling below the rotational speed of the power take-off side clutch half.  This affords the advantage that for engaging the tooth clutch the rotational speed of the normally driving shaft need not drop below the rotational speed of the normally driven shaft.  The time span, during which upon synchronization and engagement of the tooth clutch there is interrupted the power transmission, is therefore appreciably shortened.  Additionally, there are not required any special measures or facilities for protecting the pawl blocking device.

Abstract: ABSTRACT      A bulk belt conveyor has a boom joined to an upright framework or leg by a bend unit. In this bend unit the carrying run of the belt of the conveyor is supported by a train of turning rollers with the top part of the train fixedly supported along a curve while the lower part of the train is in the form of a flexible tail, the tail han-ging downwards under its own weight when the boom is in a lower position, and being supported along a curved line, for bending the carrying belt of the conveyor, when the boom luffed into an upper end or resting position. For sup-porting the tail of the train in its curved position it is possible for the tail to be made up of links withoutwardly running stops of wedge like form on one side of the tail for limiting bending of the tail. It is furthermore possible, however, for the downwardly hanging framework at the end of the run to have a ramp for supporting the rollers of the tail by way of trunnions at the ends thereof, the ramp underlapping the tail step by step as the boom is luffed upwards.
