Abstract: Abstract of the Disclosure In the process of preparing an ink blend matching a color sample, particularly an ink for multicolor printing, the solvent content and the extender content of the blended ink are adjusted to predetermined, desired values. In order to permit the printer to automatically prepare for each ink duct of the printing units an ink having the correct hue, the correct saturation and the correct color strength in accordance with the color samples, the process is carried out in such a manner that desired values for the hue, the color strength and the saturation of the color blend are determined in accordance with the color sample, the luminance factors of the color sample are ascertained by densitometric measurements using blue, green and red filters, the concentrate is prepared from ink con-centrates corresponding to a number of predetermined primary colors in accordance with the hue values which result from the measured density values, the extender is admixed in the quantity required to obtain the desired color strength, and black is admixed to obtain the desired saturation.

Abstract: ABSTRACT OF THE DISCLOSURE           A self-drilling anchor dowel has a drill head at one end of the axially elongated dowel and a truncated cone-shaped projection at the other end.  The projection fits into an adapter or holder on a drilling device.  Immediately following the drill head is a frusto-conical clamping part which tapers inwardly in the direction away from the head.          A collar extends laterally outwardly from the smaller diameter end of the clamping part.  The outside diameter of the collar is the same as the outside diameter of the drill head.  When the dowel is drilled into a receiving material, such as concrete or rock, and the collar enters the borehole formed by the dowel, the collar prevents the borings formed in the drilling operation from being discharged out of the borehole.          As the collar continues into the borehole, it compacts the borings which anchor the dowel in the borehole.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for freezing confection material includes a plurality of separate mold strips which are indexed in a closely spaced single file over several longitudinally spaced, transversely extending rows of nozzles.  Coolant is forced upwardly from the nozzles in single vertical jets which impinge perpendicularly against the mold strips midway between adjacent mold cups.  The mold cups are arranged with their wide side faces extend-ing in their direction of travel, and the single jets of coolant impinge upon support wall portions of the mold strips which extend transversely between such opposing wide side faces.  The mold strips have intermeshing end wall configurations that enable the coolant to be continu-ously sprayed without concern that the coolant may be injected upwardly between the strips to contaminate the confection material within the mold cups.

Abstract: ABSTRACT OF THE DISCLOSURE             An electrical switching circuit for a multi-phase a.c. supply uses semiconductor rectifier switches SCR1 to 5 to reversibly switch power to a multi-phase electric motor so that the motor can be run in a forward or a reverse direction.  The SCRs are provided in two sets, one for switching power to forward run the motor, and the other set for reverse running of the motor. Inductor elements .DELTA. L are connected in series with the SCRs. The inductor elements comprise coils which in-clude a non-linear permeability core, for example of ferrite or permalloy, which are operative to suppress voltage transients at switch on of the motor.  These transients would otherwise produce spurious firing of the SCRs and could produce a short circuit across the input phases of the a.c. supply.  The circuit is used in a valve actuator.  Improved torque limit switches and position limit switches are disclosed, which operate a low voltage and which use Reed and Hall effect switches.

Abstract: ABSTRACT   IMPROVEMENTS IN OR RELATING TO TELEPHONE TRANSDUCERS          An acoustic transducer of novel structure suitable for automatic assembly is made by arranging with its wall upwards a generally cup-shaped rear cover having a cylindrical wall out-turned at its upper end and extending from the rim of a base divided along a chord into a major segment for receiving an electromagnetic driving unit and a terminal receiving minor segment at a higher vertical level than the major segment. The major segment has on its inner  face fixing  lands disposed symmetrically with respect to a diameter normal to said chord offset away from the minor segment and extending inwards from the side wall.  Each fixing land is formed to define a fixing location and having on its face presented to the minor segment an upstanding locator wall.     A yoke and coil sub-assembly lowered into the rear cover is defined by a cruciform yoke plate of magnetisable material having a magnet at its centre with one pair of upturned opposite arms directed along the diameter normal to said chord the said pair of arms defining pole pieces and carrying coils and with the other pair of upturned opposite arms parallel to the said chord and formed with outturned fixing ears that settle directly on said lands behind  said  locator  wall  with  through-holes  therein aligning with said fixing locations of said lands.     Onto the yoke and coil sub-assembly is placed downwardly an armature formed with depending bearing means that settle on the magnet and permit the armature to rock thereon and a pair of torsion arms extending towards the lands and terminating in fixing ears that settle behind the locator wall on the fixing ears of the coil sub-assembly with through-holes aligning with said fixing locations of said lands. The armature has secured thereto an upstanding connecting rod. The armature is mechanically fixed from above the rear cover in tight contact with the yoke plate and the yoke plate is fixed in tight contact with the lands so that the armature is supported for vibration in said rear cover. Connector terminals are introduced through said minor segment and electrically connected to the coils. A dished diaphragm is placed downward onto the rear cover so that its rim settles on the out-turned end of the cylindrical wall and the connecting rod projects through a through-hole in said diaphragm. Then the connecting rod is adhered to the diaphragm and a front cover is assembled to the rear cover.
