Title: Wedge arrangement for removably affixing a work tool or work tool holder to a base member on mining machinery and the like
Inventor: KREKELER CLAUDE B
IPC: F16B2/14
Filed: 1976-07-16
Granted: 1978-12-19
Abstract: ABSTRACT OF THE DISCLOSURE          A wedge arrangement for removably affixing a work tool or work tool holder to a base member on mining, road working or earth moving machinery, and the like, and being particularly useful in the mining, road planing and earth digging areas.  The arrangement is such that the removable member may be readily replaced and wear and tear on the base member greatly reduced to the extent that such base member will not he destroyed or otherwise rendered useless: such base member may be a part which is permanently secured to the basic machine or it may in fact be the machine itself or some integral part thereof.  The base  member is preferably provided with n slot of a size sufficient to receive both the removable member and a wedge element; such member and element may be placed within the slot from above thereof, lateral entry of the removable member and wedge element into the slot often being unnecessary.  Means are provided to move the wedge element so as to effect a frictional engagement between the removable member and the base member to effect an interference fit in which there is no relative motion between these members and thus virtually no wear.  (It is possible to reverse this arrangement and provide the removable member with the slot and the base member with a suitable male element which, along with, the wedge element, will be received in the slot.)  The re-movable member may be provided with a bit, road planing device or  digging tooth, which working elements may in turn be re-movably affixed to and/or within the removable part.

Abstract: Abstract of the Disclosure Substantially inert gases such as exhaust gases are added to the air-fuel mixture inducted into the combustion chamber so that the weight ratio of fuel combusted in the combustion chamber and the substan-tially inert gases falls within the range from 1:13.5 to 1:22.5.  The fuel mixture mixed with such a high rate of the substantially inert gases is effectively ignited by a spark plug or spark plugs located suitably for shortening the combustion time of the air-fuel mixture in the combustion chamber.   Additionally, a reactor is installed downstream of the combustion chamber to treat the exhaust gases discharged from the combustion chamber.

Abstract: ABSTRACT OF TEE DISCLOSURE        A ventilator for use with sheet metal roofing.        The sheet metal panels covering the rood are lap-joined at the ridge of the rood and a ventilator opening is cut in the overlapped end portion of the sheet metal panels and in the under-lying roof structure on either side of the ridge of the roof.  The ventilator consists of a base member which is secured to the roof and a cover member which fits over the base member, both members being formed from sheet metal panels.  The sheet metal panel from which the base member is formed has a centrally located cut-out conforming to the size of the opening in the roof structure and has its side edge portions folded upwards and inwards upon them-selves to form flanges, and are further folded upwards at right angles to the flanges to form upstanding side walls.  The end por-tions of the base sheet metal panel are folded to form curved wind-breakers projecting outwardly between the ends of the upstanding side walls and are further folded to provide baffle walls extending between the side walls at a location close to the centrally loca-ted cut-out.  The sheet metal panel from which the cover member is formed has its side portions bent downwards at right angle to the plane of the sheet and the edge portions are then folded inwards and upwards to form reinforced side walls, while the end portions of the panel are folded downward and inwards to form angled de-flectors.    A second baffle is fitted to the under side of the co-ver member with the baffle portion being located in outward spaced apart location with respect to the baffle in the base member.        Both the base member and the cover member are bent trans-versely midway of their length to conform with the roof angle on either side of the roof ridge and when assembled, the angled de-flectors of the cover member are spaced outwardly of the wind-breakers of the base member.

Abstract: ABSTRACT:             An arrangement for simultaneous two-way data transmission of data signals with a given symbol frequency over two-wire circuits of n type found in telephone networks or of a comparable type. The arrange-ment comprises an echo canceler with an adaptive filter for producing from transmit channel signals approximated echo signals which are differentially combined with re-ceive channel signals for forming substantially echo-free residual signals.             A special type of code conversion is em-ployed in the transmit channel, whereby p-level data sym-bols are converted into modified p-level data symbols which are thereafter converted into (2p-l)-level data symbols.          The echo canceler comprises a digital adaptive filter to which the modified p-level data symbols and the resi-dual signals with a sampling frequency equal to the symbol frequency are supplied. These measures result in a trans-mission signal having favourable spectral properties, a simple inverse code conversion and an echo canceler which combines simplicity of implementation with favourable con-vergence properties.

Abstract: Abstract of the Disclosure A bellows arrangement for forming a gas leakage resistant pressure seat between ceramic heat exchange tubes has an elong-ated metallic bellows defining a central passageway with first and second ends. A metallic tube passes through the bellows and freely moves with respect to the second end of the bellows while defining a gas chamber between the tube and bellows. Axial expansion of the bellows under the influence of the in-ternal pressure when such pressure is higher than the external pressure which may be the atmosphere acts to apply a force at the interface between the bellows assembly and the ceramic heat exchange tube which is proportional to the internal pres-sure of the heat exchange tube, thereby accommodating movement of the heat exchange tube and providing a pressure seal that is leak resistant.   1.

Abstract: ABSTRACT An improved method of modifying fixed instructions in a read only memory in a data processing system is described.  The instructions stored in the read only memory are made modifiable by data stored in a random access memory.  In operation, an instruction is retrieved from the read only memory and data is retrieved from the random access memory in accordance with a previously retrieved instruction.  When the last retrieved instruction is to be modified an indexing gate enables the data from the random access memory to be combined with the last retrieved instruction in an adder or like logic device. The output of the adder or like logic device is the modified instruc-tion.  This simple arrangement enables a read only memory instruction set to be modified without limit.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a plasma display panel drive circuit using low voltage controlled self-actuating devices as clamp circuits for selection of drive lines to be driven.  Since such clamp circuits are in a normally ON condition for the sustain mode, the clamp circuits are self-actuating to transmit sustain pulses.  The clamp circuits must be selected OFF to prevent the transmission of write and erase pulses in a self-actuating mode to the selected drive electrodes so that only the desired drive electrodes receive write and erase pulses.
