Abstract: TEMPERATURE COMPENSATOR FOR A CARBURETOR                 CHOKE VALVE                        ABSTRACT         A carburetor comprises an air induction passage and a choke valve movable in the air induction passage between a fully closed position and a range of positions advanced of the fully closed position.  A predetermined second position of the choke valve is located within this range of positions.  A stop mechanism is selectively movable into and out of the path of movement of the choke valve to prevent and permit choke valve movement from its second position toward its fully closed position.  A thermo-sensitive element controls the movement of the stop mechanism such that the stop mechanism is disposed in the path of choke valve movement whenever the ambient temperature around the carburetor exceeds a predetermined level.

Abstract: ABSTRACT OF THE DISCLOSURE    In a data processing system, a system memory includes first memory modules having a data path of a first bit width and second memory modules having a data path of a second bit width with the first bit width being less than the second bit width.  A central subsystem includes a cache memory unit and processing units for initiating requests for data transfers of the second bit width between the system memory and the subsystem processing units.  An interface coupling the system memory and the central subsystem for bidirectional data transfers generates, in response to a memory request of a second bit width wherein the requested data is stored in a first memory module, additional memory requests until sufficient data has been retrieved from the system memory to satisfy the central subsystem request.          The interface also monitors data transfers between the system processing units and the system memory and transfers the data transfers to the central subsystem in order to update and to re-tain the integrity of the cache memory in the central subsystem.

Abstract: ABSTRACT            A hermetic seal, primarily for compressors (12) for use in refrigeration of air conditioning systems but having use in apparatus wherein a seal is required between two elements (14, 14) reciprocating substantialy distances relative to each other, comprising a bellows having a plurality of sections of convolutions (17, 19, 21) with positive displacement means (25, 26, 27, 28) associated therewith that assures simultaneous movement of most of the convolutions upon rapid acceleration of relative movement between the two elements.  This prevents excessive stress and strain on any one or more convolutions or on the end convolutions in particular, that could cause failure thereof, by distributing  he stress over a large number of the convolutions rather than just a few at any one instant.  The stress in each convolution of the bellows depends upon the natural frequency and spring rates of any given bellows diameter and number of convolutions.  Also, the stresses in the various convolutions depends upon the location  of and the number of sections that have positive displacement means for actuation thereof,  (engine) speed and piston acceleration.  By proper selection of the number of convolutions in each section, which should decrease in numbers sequentially from a fixed end thereof to a movable end thereof, it is possible to make a bellows of substantial length wherein the maximum stress level in each bellows section will be substantially equal.

Abstract: ABSTRACT:               COMBINED SHIFT CONTROL A combined shift control for a change speed gear transmission and a two-speed axle for motor vehicles, whereby, for instance, a five speed gear box with one reverse gear is extended to provide a seven speed gear box with one reverse gear.  The gear box includes three parallel shift rods (12, 13, 14) each carrying a respective selector block (15, 16, 17). The slot (18) of the fourth/fifth selector block (17) is is deeper than usual so that the gear lever (21) can operate it in two different transverse positions.  In one position the gear lever (21) actuates the fourth and fifth gears, but in the second position, after overcoming a spring-loaded plunger (20) and operating two micro-switches (24) which serve to change the axle ratio to a higher value, the gear lever (21) effectively actuates two further gears (sixth/seventh) when selector block 17 is caused to move the shift rod 14 to engage fourth and fifth gears again.  In order to retain the gear lever (21) in the high axle ratio position when the driver lets go of the lever means such as a slidable gate (22) which is locked into position when the higher axle ratio is selected via the micro-switches (24) are provided.  Alternate forms of switch and retaining means are described with reference to other Figs.  An embodiment is disclosed (Figs. 12, 13) for use with a selector finger mounted on a cross shaft rather than a pivotable gear lever of Fig. 4.

Abstract: SPEECH RECOGNITION MICROCOMPUTER      Abstract of the Disclosure A simplified, speaker independent, selected vocabulary, word recognizing microcomputer functions without the use of a typical front end filtering network.  The microcomputer identifies vowel-like fricative-like, and silence signal states within a word or phrase by counting speech pattern zero crossings during sequential time periods.  Variable zero crossing count thresholds are used to identify states based upon previously identified states, and histeresis is provided, through the use of state time measurement, to prevent state oscillations which would result in erroneous state sequences.  The microcomputer, by monitoring zero crossings, defines words as a sequence of vowel-like, fricative-like, and silence states.  By limiting the recognizable vocabulary to words which have dissimilar sequences, the incoming speech pattern may be recognized by comparison with state templates defining the limited vocabulary stored in the microcomputer's memory.

Abstract: ABSTRACT OF THE DISCLOSURE       _ _    . . . _ _ A process is disclosed for the manufacture of glass sheets, particularly electrically heated backlites (EHB's).  The process includes the steps of selecting a glass sheet and then applying an opaque band to a surface of that sheet. The opaque band is formed from a radiation curable paste which includes both a filler material which can fuse to the glass sheet when heated to a fusion temperature and a radiation curable material which is heat decomposable into components which are nonreactive with the glass sheet when heated to a fusion temperature.  The radiation curable material is cured thereby to form a temporary bond of the radiation curable paste to the surface of the glass sheet.  As an optional step in order to form an EHB, a pattern of electrically conductive material is deposited on the surface of the glass sheet. This conductive material contains at least one component which is heat fusable with the surface of the glass sheet when heated to the fusion temperature.  The glass sheet is passed through a heating lehr which heats the various elements to the fusion temperature whereby the fusable materials are fused to the surface of the glass sheet and the radiation curable material is heat decomposed into components which are nonreactive with the surface of the glass sheet.

Abstract: Abstract of the Disclosure In accordance with one embodiment of this invention, a bis-(cyclopentadienyl)chromium(II) compound is introduced onto an activated phosphate-containing support and utilized in conjunction with an organo-metal cocatalyst, such as an alkylaluminum. In accordance with another embodiment of this invention, a phosphate-containing zerogel is formed by removing water from an aluminum phosphate-containing hydrogel by means of azeotropic distillation or washing with a volatile, water mis-cible organic compound, activated and thereafter a bis-(cyclopentadienyl)-chromium(II) compound is incorporated therewith. In other embodiments of this invention, a phosphate-containing support is formed by forming alumi-num phosphate from an aluminum alkoxide or from a melt, or by phosphating silica or alumina, or by forming an aluminum phosphate/silica combination. A support thus formed is activated and a bis-(cyclopen-tadienyl)chromium(II) compound added. Alternatively in all embodiments, the chromium and phos-phate components can be added separately. The resulting catalysts are capable of giving narrow molecular weight distribution polymer because of the inherent high molecular weight of the polymer produced, and the unusual sensitivity to hydrogen, a broad spectrum of polymers can be produced so far as molecular weight is concerned. The catalyst is ideally suited for forming olefin polymers such as ethylene and ethylene copolymers in a slurry system.
