Abstract: ABSTRACT OF THE DISCLOSURE         A position detecting and control system for a vehicle including a low frequency transmitter and associated antenna with an associated fault indicating circuit, and a receiver and associated antenna  with an associated fault responsive circuit. one of the antennas is mounted on the vehicle so the distance between the antenna carried by the vehicle and the other antenna is determined by the amplitude of the signal induced in the receiving antenna.  The frequency of the transmitter is such that the distances to be monitored are a small fraction of the wave-length of the frequency involved, and any significant signal variations due to signal reflections which can reinforce or can-cel the received signal are avoided.  When the transmitter and receiving channels are operating properly the system monitors at least two different spacings between the transmitting and receiving antennas where the signals received at the receiving antenna are of widely different orders of magnitude.  Separate range detecting circuits are coupled to a common point of the receiver, each of which includes an attenuator at the input thereof for adjusting the level of the signal to be fed to an associated signal level detector which operates a control device when the signal at the receiver output point involved reaches a level indicating the associated spacing to be monitored.

Abstract: ABSTRACT     The invention relates to a clamping ring and closure means made of plastic material comprising a closure head integrally formed at one end of a clamping ring  of U-shaped section and which has a passage into which the opposite end (in the form of a tongue) of the clamping ring, can be inserted.  Interlocking saw or locking teeth are provided on the side edges of the tongue and on the side walls of the passage, and the side walls of the closure head are connected together by non-overlapping spacer webs which bound the passage on the upper side of the closure head and at the exterior of the base of the clamping ring.     The sawteeth on the two side walls are in each case disposed opposite one another at the points of attachment of the spacer webs, and the saw or locking teeth on the tongue, extend outwardly at an acute angle in relation to the longitudinal axis of the clamping ring.  The end surfaces of these teeth extend approximately perpendicularly to said longitudinal axis, and along one side edge of the tongue a reinforcing strip is formed which projects in the direction of the open section side of the clamping ring and whose inner side is provided with sawteeth. The locking teeth formed on this side edge are widened  over the outer side of the latter so that the lower spacer webs lying at the exterior of the base of the clamping ring section have, in each case, a portion which lies at the extremities of the limbs of the U-section and which is offset in step form bounding a deeper portion of the passage corres-ponding to the reinforcing strip, a bent-over portion of the spacer webs having a sawtooth facing the deeper portion of the passage.

Abstract: ABSTRACT         The invention provides a process for recovering aluminium values from aluminium-containing minerals, such as oxides of aluminium and aluminosilicates.       The process involves heating an intimate mixture of an aluminium-containing mineral and a solid carbonisable organic material, preferably a fibrous cellulosic material, so as to carbonise the organic material, and chlorinating the solid residue from the carbonisation step.  The solid residue contains carbon in very finely divided form distributed throughout the aluminium-containing mineral,  The surface area and reactivity of this carbon is much higher than that of powdered coal and the chlorination reaction thus takes place in a most efficient manner.

Title: Paralleling of inverters for low harmonics
Inventor: KLEIN FRANK N
IPC: H02M7/49
Filed: 1976-05-04
Granted: 1978-10-24
Abstract: ABSTRACT OF THE DISCLOSURE         Two switching-type three-phase inverters are connected to supply electrical power to a common load in such a way that the load voltage has lower harmonic content than that of either inverter alone.  Harmonic content is reduced by interconnecting the inverters by means of transformers to cancel some of the harmonic voltages, but a main component of output power of one of the inverters is used directly without being trans-formed, so that the total required KVA of the transformers is relatively small.  Each phase of load voltage is produced from four or six component phasors, by adding two or three voltages from one of the inverters and two or three voltages from the other.

Abstract: Abstract of the Disclosure Water-containing solid fuels, particularly brown coal or lignite, must be dried before conveying to a gasification reactor operating under pressure.  A process is provided for treating the coal whereby water or steam is added to the coal to yield a mix-ture having a ratio of water to coal (computed on a dry basis) of approximately 2.5-3.5 to 1.  The coal-water moisture is then maintained at a temperature of approximately 200-300°C and a pressure higher than that of the gasifier and in the range of about 15-110 bars until the coal has substantially lost its colloidal structure and the water separates from the coal in liquid form.  After separation from the water, the coal is transported to the gasifier. Preferably, the solid fuel used has a granular par-ticle size of about 0.1 to 10 mm and the coal-water mixture is pre-heated prior to pressurization.  Op-tionally, the dried coal may be heated and/or lowered in pressure prior to entering the gasifier, and residual adhering water may be removed by post-treating with heated or unheated inert gas.

Abstract: ABSTRACT OF THE DISCLOSURE              Apparatus for baiting fishing hooks attached at spaced intervals by snoods to a long line comprising guide means for receiving the lines, snoods and eyes of the hooks to channel them longitudinally and unobstructedly through said apparatus and restrict them against lateral displacement out of the guide means.  Orienting and tensioning means, laterally offset from the guide means, momentarily engage each hook to progressively rotatably orient it while increasing the tension on the hook and its associated snood.  As the hook then leaves the orienting and tensioning means, it flips into a baiting chamber to securely impale bait supplied thereto.  The baited hook leaves the apparatus together with the snood and main line, thus reducing the chance of loss of bait by a whiplash action, in which the hook and snood have to be separated from the main line before passing through the baiter.  In addition, according to the present invention, the hook orientation is carefully controlled from the moment the hook enters the apparatus to the moment it leaves the orienting and tensioning means, to ensure effective baiting.

Abstract: ABSTRACT         First and second pairs of mirrors are oriented to intercept first and second regions, respectively, of a diffraction pattern and deflect these regions to individ-ual detectors so that simultaneous analysis of the regions of the diffraction pattern can be carried out. The pairs of mirrors can be spaced along the optical axis in a man-ner to provide focused regions of the diffraction pattern at the detectors wherein the diffraction pattern itself is imaged at two spaced focal planes resulting from astig-matic conditions.  The physical arrangement not only over-comes problems introduced by astigmatism but also permits practical physical positioning of individual photo-diode arrays such that simultaneous processing of the regions in the diffraction pattern can be carried out.
