Abstract: The invention relates to a method of making a metallic strip-type composite article adapted for expansion by the application of internal pressure to provide a plurality of tubular passageways therein. This method comprises providing a pattern of weld inhibiting or stop-weld material between two superimposed strips of metal and pressure welding these strips together so that the adjacent areas of the strips which are not separated by the stop weld material become bonded together, forming the composite article. The outer surfaces of these two metal strips are provided with a clad layer of brazing alloy. At any suitable time after the bonding, the areas defined by the pattern of weld inhibiting or stop-weld material may be expanded in the composite article to form multi-holed strip-type tubing clad with brazing alloy. The novel multi-holed strip-type tubing clad with brazing alloy can be used for producing heat exchanger assemblies and other products in which a brazed form of construction is used.

Abstract: An amorphous silicon semiconductor alloy (32 and 34) having multiple layers (38 and 58) (42 and 60) is used to form a photoelectrode (either a photoanode (14) or a photocathode (16) for use in a photoelectrochemical cell (10) for the photoelectrolysis of water to produce hydrogen or the conversion of solar energy into electrical energy. Each layer of the semiconductor alloy has a different dopant concentration ranging from no dopant to a heavy dopant concentration. The semi-conductor alloy of the photoelectrode is a -Si:F:H or a-Si:H x  deposited on a reflective layer (28 and 30) of aluminum of molybdenum which is deposited on a substrate (24 and 28) of glass or stainless steel. A tunnelable oxide layer (62) can be deposited or intrinsically formed to cover and protect the top surface (60) of the semiconductor alloy body. The photoanode is of an n-type configuration while the photocathodes can be either a p-type or a P-I-N type configuration.

Abstract: The invention provides a coffee machine, with a housing, a fresh water supply reservoir mounted therein, a heating means adapted to heat the fresh water and a feeding pump to supply the heated fresh water to a brewing chamber under pressure. The brewing chamber comprises a closure means and an inlet for coffee powder as well as an outlet for coffee. If appropriate, an installation for pushing out and removing, respectively, the leached-out coffee powder out of the brewing chamber and from the brewing chamber, respectively, may be provided. All parts of the apparatus which are subjected to contamination by the coffee powder or by the coffee, namely the brewing chamber, the closure element, the coffee powder inlet, the coffee outlet and eventually the installation for pushing-out and removing the coffee powder, are combined to a modular unit, which is removably inserted into the housing of the apparatus. The remaining parts, particularly the water reservoir, the heater and the pump as well as the required driving, control and operating elements are fixedly installed in the housing and are adapted to be operatively coupled to the modular unit upon insertion thereof into the housing. Thereby the contaminated parts can be cleaned easily and without danger, since the modular unit can be pulled out of the apparatus and rinsed as a whole.

Abstract: In a time base corrector incorporated a video tape recorder, if a time during which a vertical synchronizing signal is written in a memory unit (2) exceeds one horizontal period segment, the video signal stored at the first address of the memory unit (2) is dropped out during data reading operation. To overcome the above problem a write address designation signal (ADW) is once latched in response to a vertical synchronizing signal (PBV) a predetermined number is subtracted from the latched address number; the subtracted a address number is loaded in a counter (16) in response to a reference vertical synchronizing signal (REFV) and is incremented in response to a reference horizontal synchronizing signal (REFH) in order to shift the read start address, thus preventing video signals stored in the memory unit (2) from being dropped off.

Abstract: In an oversampling type digital-to-analog converter, which has.a light gradient overload and a high signal-to-noise ratio in spite of a comparatively low sampling frequency, the difference (1-1) between an oversampled digital input signal (xn) and a feedback signal (qn) is taken, such differences are integrated (1-2), the integral value is quantized (3) to obtain the feedback signal (qn), and part of the feedback signal is used as an analog output signal. The circuit (3) for the quantization is constructed of a circuit which converts the integral value into a digital signal smaller in the number of bits than the digital input signal (xn), and the feedback signal (qn) is obtained by integrating the outputs of the quantization circuit (3) by means of a digital integral circuit (1-4).

Abstract: A system for detecting missing or crossed cords in cord reinforced tyre fabric. The entire width of the fabric as it is being made is scanned by a highly collimated X-ray source and a sensor. A change in the amount of X-ray radiation penetrating the fabric indicates the presence of the cords. A counter which counts at a fixed rate is gated on during the time that a cord's presence is detected. The total count in a small section of the fabric, called a slice, is proportional to the number of strands in the slice. Since the counting rate is relatively high with respect to the scan time, the system can easily detect missing or overlapping cords.
