Abstract: A machine control panel includes a matrix of pressure sensitive switches (10) and a matrix of LED's (12) in a substantially coplanar array. An aperture array (18) formed by a flexible cover sheet (16) having an opaque coating (20) surrounding a matrix of transparent apertures (18) is positioned on top of the LED and switch array with corresponding ones of the LED's and apertures in alignment. Unused apertures in the aperture matrix corresponding to unused LED's are selectively closed by opaque aperture covers (19). Switch identifying covers in the form of labels (22) are positioned on top of the aperture array to visually indicate selected ones of the switches (16). A flexible transparent overlay located on top of the aperture array may be used to protect the labels and aperture covers white enabling a switch operating pressure to be transferred to the switches.

Printing is effected by vaporization of a portion of ink in a section of the nozzle between the electrodes, which expels the said depth of ink. the container is closed by an insulating plate (30) over which extends a metal strip (37) of smaller width than the diameter of the nozzle. The nozzle is formed by means of a single hole through the plate and the strip, whereby the strip is separated the two electrodes. The metal strip may be disposed between the plate and a front dielectric alyer43. The latter may also be covered by a second insulating layer having a front part of the nozzle therethrough, while the first dielectric layer may have a hole which is larger in diameterthan the nozzle so as to create a reserve of ink for the frequent dots. For a multi-nozzle head, the nozzles are produced through an insulating plate over which extend the strips for a plurality of pairs of electrodes.

Abstract: Disclosed is a method for continuous production of anhydrous potassium tert.butoxide from aqueous potash lye and tert.butyl alcohol in a packed distillation column. The water of reaction and the water brought in by the starting products is distilled out at the top of the column with the aid of a withdrawing agent. In the bottom of the column an alcoholic solution of the potassium tert.butoxide is produced, which is withdrawn and then processed for isolation of the anhydrous salt. The tert.butyl alcohol is used in excess such that a 10 to 18 weight-percent solution of the salt in alcohol is produced in the bottom of the column. The amount of tert.butyl alcohol together with the amount of the withdrawing agent is selected such that the tert.butyl alcohol content in the gas mixture at the center of the column will be between 50 and 90% by weight. The bottom of the column is continuously maintained at ebullition. A gas mixture of 20 to 50 wt. -% of tert.butyl alcohol and 50 to 80 wt. -% of the withdrawing agent is withdrawn from the top of the column at a temperature between 65 DEG  and 75 DEG  C. Cyclohexane or hexane is used as withdrawing agent in accordance with the invention.

Abstract: In a self-service shop, sales packages are used for sewing implements of various type and/or thicknesses, such as knitting needles, which implements are employed for the manual production of tied, woven, knotted or meshed sheet-like yarn structures, such as knitted fabrics. These sales package is designed as a blister package and possesses a base plate with a transparent bowl attached thereto, in which sewing implement is accommodated. In order to demonstrate an obvious use of this sewing implement, it is proposed that the base plate be employed on the display side, in a visual illustration, as a tensioning surface for a sheet-like structure which can be produced as a yarn product by means of this sewing implement. This yarn product also extends over the region of the transparent dish, so that the sales package simultaneously forms a visual member for the yarn product of the specific type, the transparent dish simultaneously forming the glass cover for the visual member. <IMAGE>

Abstract: A two-pole limited angle torque motor (1) including a rotor assembly (2) having one or more permanent rotor magnets (5) and a stator assembly (6) including a stator coil (9) and a pair of circumferentially spaced stator pole structures (10, 11). Each pole structure (10, 11) includes a generally axially extending stator pole blade (14) about which the stator coil (9) circumferentially extends. A radially outwardly extending flange (15) is at one end of one of the stator pole structures (10) and at the opposite end of the other stator pole structure (11). The stator pole blades (14) have a greater radial thickness (20) adjacent the flanges thereof than at the opposite end of the blade to reduce the magnetic flux density of the stator pole structures in the region of the blades adjacent the flanges thereof. Also, the axial outer end faces (21) of the flanges (15) desirably protrude axially outwardly adjacent the radial inner ends thereof to make use of the fringing fields of the rotor magnet at the ends of the rotor assembly to increase the reluctance torque of the motor. At the ends of the stator assembly (9) opposite the stator pole flanges (15) on opposite sides of the rotor assembly (2) are additional stator pole pieces (24). The blades (14) of the stator pole structures (10, 11) terminate short of the other ends of the rotor magnet (5) to provide room for the additional stator pole pieces (24) at such other ends for a given rotor length whereby the motor has a substantially higher reluctance torque without significantly reducing the torque due to interaction of magnetic fields. Surrounding the stator assembly in an outer magnetic housing (16) comprising two semi-cylindrical parts (30, 31) with air gaps (17, 18) between opposite sides thereof, said housing parts being rotatable relative to each other to change the size of one gap relative to the other or otherwise machinable to change both gaps equally for adjusting the reluctance torque of the motor.

Abstract: Apparatus (10) for the concentration and beneficiation of particulate matter by froth flotation employs a constriction plate (14) which separates verti­cally arranged flotation (17) and hydraulic (18) com­partments. A discharge duct (29) may be used to extend through the hydraulic compartment (18) and to open through the constriction plate (14) centrally thereof. Orifices (16) in the constriction plate (14) are in communication with the hydraulic compartment (18) to provide a uniform dispersion of air bubbles in the flotation compartment (17). Aerated water distribution manifolds (22, 42) within the hydraulic compartment (18) and within the lower portion of the flotation compart­ment (17) are provided to enter the aerated water into the flotation compartment substantially uniformly throughout a horizontal cross-section thereof. In order to minimize the energy consumption of the apparatus (10) and to provide for the introduction of aerated water at a reduced flow rate, amenable to the separation of aqueous pulps having a low concentration of solid matter by volume, such as sulfides, a stream of pressurized air is passed through an eductor (53) wherein a mixture of water and, if desired, an appropriate surfactant is aspirated into the stream of flowing pressurized air. The flowing stream of pressurized air and the aspirated water and surfactant are then passed through a venturi region (59), producing a highly aerated, low water volume stream of aerated water for delivery to the hydraulic compartment (18).
