Abstract: 1. Process for the production of stepped windows in layers consisting of insulating material (4) and electrode material (3) in the formation of an integrated semiconductor circuit, in which said layers are applied one above another on a semiconductor body or on a layer (2) arranged thereon, and are etched away with the aid of lacquer masks (5, 6) to such an extent that the lower layer (3) which is adjacent to the semiconductor body projects beyond the edge of the layer (4) which is arranged on top, characterized in that a single lacquer mask is used, and in that : - a) after the application of the layers (3, 4), the lacquer mask (6) is applied to the layer (4) which is arranged on the top, and the mask openings of the lacquer mask (6) are so selected that they lie above the windows which are to be etched into the lower layer (3), and are somewhat smaller than these windows ; b) subsequently, the upper layer (4) is selectively etched away through the mask opening, whereby the lacquer mask (6) is underetched by a predetermined length ; c) the lacquer mask (6), possibly after previous swelling, is heated above the flow point until it is deposited on the parts of the surface of the lower layer (3) exposed by the underetching ; and d) finally, the surfaces of the lower layer which are exposed by the lowered lacquer mask (5) are etched away.

Abstract: A coupling unit, for example, for automatic irrigation apparatus, comprises a probe (32) arranged to connect within a mouth (33) of a hydrant to receive a water supply from the supply line (B) connected to the hydrant. The probe (32) is mounted on a chassis (14). The chassis has two wheels (10) by means of which it rides on an upper surface of the supply line (B) and guide wheels (12) which engage the side to the supply line (B) so that the coupling unit will follow the supply line (B). The chassis (14) is also supported from a steering head (28) and a flexible coupling including a bearing (29) and a jack (31), permits limited relative movement between the probe (32) and the steering head (28) to accommodate misalignment of the probe (32) with the mouth (33) of the hydrant. In an alternative embodiment the probe (32) is flexibly mounted on the chassis (14) which is fixed. In both embodiments a sensing mechanism (60) enables the probe (32) to be tilted relative to the hydrant.

Abstract: Under the I/O protocol required by conventional computer architectures, peripheral devices communicate with each other via the CPU of a host computer. That requirement necessitates two separate data transfers and cuts the data transfer rate by one-half. 
     This invention discloses a data processing system having an architecture that will allow high-speed direct device-to-device data transfers independently of a computer memory. The system consists of a host computer (10) interconnected with a remote signal processing subsystem (12). A Direct Device Access Bus (18, 20) and a plurality of data processing devices (22,24, 26, 28) are provided. A controller (16) associated with a Signal Processing Subsystem supervisor (14), selectively interconnects desired ones of a set of data processing devices via the Direct Device Access Bus (18, 20) to provide direct communication between the selected devices within a set. Several sets of devices can be serviced concurrently by the technique of dynamic time slot allocation.

Abstract: A cyclic adsorption process is provided in which two zones are employed - an adsorption zone and a heat storage zone. The adsorption zone consists of an adsorbent material and a heat capacity material in amounts sufficient to provide for the rate of progression of the thermal front through the adsorbent to be substantially equal to the rate of progression of the mass transfer front through the adsorbent when a fluid mixture containing an adsorbate for removal by adsorption is passed through that zone. The heat storage zone consists of a heat capacity material. In operation, as an air drying process for space conditioning, for example (see figure 5) ambient air (101) is passed through the adsorption zone (2) and then through the heat storage zone (3). The moisture in the air is adsorbed by the absorbent and a portion of the sensible heat of the air stream and the heat of adsorption is stored in the adsorption zone (2) for at least a portion of the cycle and a portion of the heat is stored in the heat storage zone (3). Thus, the hot dry air leaving the adsorption zone has its temperature lowered in heat storage zone (3). The dry air (108) then is cooled further in an evaporative cooler (104). During regeneration of the adsorbent, a fluid regenerating stream such as warm moist air from conditioned space (106) is passed through the heat storage zone (3) where it is partially heated. At a point between the adsorption zone and the heat storage zone the regenerating fluid stream (112) is further heated, via an additional heat source (102), and passed through the adsorbent zone (2). The amount of additional heat is sufficient to effectively desorb the adsorbent.

Abstract: An anode with a base of lead or lead alloy is provided with catalytic particles of titanium which comprise a very small amount of platinum group metal or an oxide thereof. 
     These catalytic particles are partly embedded, anchored and electrically connected to the base, so that oxygen. is evolved on these particles at a reduced potential at which the underlying lead or lead alloy of the base remains electrochemically inactive, and the anode base thereby serves only as a stable conductive support to the catalytic particles. 
     Operation of this anode at a reduced potential provides energy savings. It may be used more particularly in cells for electrowinning metals with a higher degree of purity at a reduced energy cost with respect to conventional cells equipped with anodes consisting of lead or a lead alloy.
