Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a heat exchanger panel for use in a solar energy collector system.  The panel includes a plurality of spaced parallel internal tubular passageways connecting opposed headers defined by numerous island-like bonded portions connected by a plurality of tubular channels passing therebetween.  The headers are generally triangular in shape and include entry and exit portions to the panel.  The entry and exit portions are laterally displaced from the center of the panel to permit a heat exchange medium to flow into the panel and across the headers so that the medium flows through each of the plurality of spaced parallel individual internal tubular passageways connecting the headers.  At least one of the headers includes as part of the bonded portions alphanumeric indicia to define and assist in the correct placement of the panel within the collector system.

Abstract: 21.8.1979                   1                   PHN.9292 ABSTRACT:             A digital-to-analog converter is described for converting (b+a)-bit code words into an analog signal by means of a b-bit auxiliary digital-to-analog converter. In order to reduce the quantizing noise introduced by the indispensible quantizing of the (b+a)-bit code words for obtaining the b-bit code words these (b+a)-bit code words are applied to an integrating network which has its output connected to an amplitude-limiting device which brings the integrated signal in the signal range of the auxiliary-D/A converter. The output signal of the amplitude-limiting device is now quantized and this quantizing signal is ap-plied to the auxiliary D/A converter which produces analog output signal samples which are applied to, possibly, an analog output filter through a cascade arrangement of an am-plitude-restorer and a difference network.            The (b+a)-bit code words are assumed to occur with a frequency which is higher than the Nyquist sampling frequency associated with the analog signal represented by these (b+a)-bit code words.

Abstract: TIRE PRESSURE COMMUNICATION DEVICES     ABSTRACT OF THE DISCLOSURE           Disclosed are devices for transmitting signals from a rotatable tire to a stationary recei-ver which correspond to the internal pressure of the tire.  In one embodiment, a Bourdon tube communicates with internal tire pressure to regulate the magnetic gap of an electromagnetic induction configuration. Changes in the magnetic gap result in corresponding changes in an output signal strength.  In another embodiment of the invention, a bellows is provided in communication with tire pressure for regulating the position of the core of an LVDT.  The core position and, accordingly, the output of the LVDT corresponds to tire pressure.  In yet another embodiment, strain gauges or other appropriate electrical signal genera-tors are connected to the tire and interconnected with a rotating race.  A plurality of ball bearings are maintained in a preloaded condition between the rotating race and a stationary race, the latter race communicating signals to a tire pressure meter or the like.     .

Abstract: Abstract The invention relates to an optical information processor comprising a semiconductor laser device which has a rectangular light emitting region, a disk, and an optical system which includes a prism for converting a non-circular beam emergent from the laser device into a circular beam, the circular beam being projected onto the disk by the opti-cal system thereby to record or play back predetermined information.  This means of converting a non-circular beam into a circular one avoids the prior art disadvantage  of reducing the amount of light reaching the disk and thus the efficiency of the laser device.

Abstract: ABSTRACT OF THE DISCLOSURE          A soap solution dispenser for use in public and private lavatories, washrooms and so forth, has a refill cartridge for aqueous  soap solution.  This exchangeable refill or supply cartridge has a flexible connecting member mounted upon a hollow plug element of a solution level indicator.  During use of the dispenser, first the cartridge is emptied, then the solution level indicator, and only then a reservoir within the dispenser.  Thus, the contents of the cartridge can be used up completely, while the dispenser still remains operative because of the reservoir volume, until such time as the cartridge can be conveniently replaced.  For higher contrast indi-cation of the solution level, the indicator can contain an optical body or element which is immersed in the soap solution.  The optical element only becomes totally internal reflecting when the refill cartridge is empty.          Prisms can be provided so as to optimize the use of existing sources of light, and optical filters can be employed for an indication in color.

Abstract: TITLE: FLUID FILTER AND INDICATOR INVENTORS: BRIAN A. FOORD and DONALD C. LEUTZ                       ABSTRACT   A versatile filter structure adaptable for use in differently ported configurations includes accommodation for variations of bypass and shutoff valving and for filter element replacement from either end or centrally of the structure. A head casting is secured to a tubular housing and either may be the mounting device for the filter. A funnel shaped diverter having an oblique edge is removably mounted in the head casting and provides separation between inlet and outlet portions of the filter structure by means of an eliptical o-ring seal at the edge which engages the interior of the head casting. The diverter provides a smooth transition for fluid flow to the interior of the filter, supports one end of the filter element in the tubular housing, optionally houses a shutoff valve operative automatically upon filter element removal, and further houses a bypass valve for safeguarding against filter element blockage. The remote end of the housing which also supports the filter element consists in the different configurations of a welded-closed or removable end assembly, with or without a port and shutoff valving. An indicatormounted on the head casting is in fluid communication with opposite sides of the o-ring seal to monitor inlet and outlet pressure differentials. Dual diaphragms actuate and isolate a sensing piston in the indicator and a dual spring arrangement biases the piston for normal operation and to provide an indication of lack of filter element in the housing.
