Abstract: - I -ABSTRACT OF THE DISCLOSURE       "THERMOPLASTIC POWER TRANSMISSION BELTS"     A method of manufacturing a thermoplastic transmission belt having a reinforcing element in the form of a tape woven from synthetic filamentary fibre yarn and an apparatus for performing the method.    A thermoplastic body element is extruded around the reinforcing element.  The reinforcing eliminates heated prior to the extrusion stage and after extrusion the formed belt is cooled.  The reinforcing element is held in tension during the heating, extruding and cooling stages.  A constant tension is applied to the reinforcing element by suspending a discrete weight from the reinforcing element.  A haul-off mechanism is provided and comprises two rotatable opposed endless belts which grip the formed belt to pull the reinforcing element through the apparatus.  A bonding agent may be applied to the reinforcing element by passing it through a dip tank.

Abstract: ABSTRACT OF THE DISCLOSURE     A digital circuit requiring minimum power for accurate-ly and reliably measuring the average pulse rate of a periodic signal.  The circuit includes a plurality of flip-flop stages adapted to be configured by control gates either as a binary counter or a shift register in response to the pulses of the pe-riodic input signal.  Through a series of configuration gates, each pulse momentarily configures the circuit as a shift register and effects a shift operation, e.g. a divide-by-two operation. After each pulse, the circuit resumes a counter configuration and counts the clock pulses of a crystal controlled clock oscillator. After a few input pulses, the contents of the counter immediately after each shift operation indicates the average periodic rate of the periodic signal in much the same manner as a conventional R-C network.  However, the digital circuit is not suseptable to drift caused by temperature changes and also moderates the effects of momentary irregularities in the periodic rate of the signal.  In application of the digital circuit, a digital comparator of an implanted cardiac cardioverter compares the counter contents with a preset value which, when exceeded, triggers a cardiac analyzing circuit which determines whether the automatic cardioverter is appropriate.

Abstract: Improved Methanol Carbonylation Process Abstract of the Disclosure  An alcohol such as methanol is reacted with carbon monoxide in a liquid reaction medium containing a rhodium catalyst stabilized with an iodide salt, especially lithium iodide, along with alkyd iodide such as methyl iodide and alkyd acetate such as methyl acetate in specified proportions.  With a finite concentration of water in the reaction medium the product is the carboxylic acid instead of, for example, the anhydride.  The present reaction system not only provides an acid product of unusually low water content at unexpectedly favorable reaction rates but also, whether the water content is low or, as in the case of prior-art acetic acid technology, relatively high, is characterized by unexpectedly high catalyst stability; i.e., it is resistant to catalyst precipitation out of the reaction medium.

Abstract: PREPARATION OF AROMATIC                    CARBONYL COMPOUNDS     ABSTRACT     Aromatic carbonyl compounds, in particular arylene ether ketones, are prepared by reacting an appropriate reagent system in the presence of free Lewis acid and a complex bet-ween a Lewis acid; for example, aluminum trichloride, and a Lewis base, for example, N,N-dimethylformamide, and, optionally, a diluent, such as methylene chloride.  The pro-cess is particularly advantageous for the preparation of substantially or all para-linked arylene ether ketones as the presence of the Lewis acid/Lewis base complex markedly reduces alkylation and ensures the substantial absence of ortho substitution.

Abstract: ADJUSTABLE LOAD, FRICTION FEED, QUICK TEAR BAR MECHANISM Abstract of the Disclosure An adjustable load tear bar mechanism for a friction feed platen (15) that comprises a tear bar assembly (31) and spring loading mechanisms (33) is disclosed. The tear bar assembly (31) comprises a tear bar (51) mounted between a pair of side arms (41, 43) located on opposite ends of the platen (15). The tear bar (51) is an inverted, generally U-shaped channel. Positioned in the channel is a roller shaft (45) on which a plurality of friction feed rollers (47) are mounted. The downstream ends of the side arms (which overlie the platen) are pivotally attached to walls (11, 13) of the printer chassis. The tear bar (51) and roller shaft (45) extend between the upstream ends of the side arms (41, 43). Mounted on the roller shaft (45) so as to be rotatable therewith are arm hooks (53, 55). One of the arm hooks is part of a detent mechanism that includes teeth (125) that co-act with a spring (59) and plunger (57) housed in one of the side arms (43). The position of the teeth (125) and, thus, the rotational position of the roller shaft (45) is controlled by a detent lever (121).  The arm hooks (53, 55) are attached by the spring loading mechanisms (33) to the printer chassis. More specifically, the hook arms are attached by hooks(165) to springs(163) mounted in housings(161) connected to the printer chassis upstream of the tear bar (51). The position of the arm hooks (53, 55), which control the pressure applied by the tear bar (51) and friction rollers (47) to the platen (15), is controlled by the latched position of the detent mechanism.

Abstract: Abstract of the Disclosure Sensor Mounting Arrangement Sensors of the type capable of delivering a signal representative of the rotated position of an output member frequently fail prematurely because of excessive side and axial loading and electrical conductor damage.  A mounting arrangement for a first sensor has an apparatus for connecting an input shaft of the first sensor to an output member, and an apparatus for connecting a body of the first sensor to a housing and maintaining the body against rotation about an input shaft axis and thereby reducing the force applied to the sensor body caused by wobble of the first sensor.  The mounting arrangement has a connecting shaft and guide assembly, which guides and protects an electrical conductor both internally and externally of the housing, and the first apparatus permits the passing of the electrical conductor thereby.  Therefore, premature failure of and damage to the electrical conductor and the first sensor is substantially reduced.  The sensor mounting arrangement is particularly suited for use on a steering axle assembly of a work vehicle.

Abstract: A B S T R A C T      Face-gear  transmissions have  been  used  hitherto  only  for secondary applications, with little running hours and low loads. They  form  a  type  of  underdeveloped  angle  transmissions.  When analysing said underdevelopment  it was  surprisingly found that well-known gear theory had not been applied correctly. Especially the teeth-tip-height can be increased considerably in the region where the face-gear teeth have increased pressure angles, resulting in considerably increased loading capacity and meshing quotient, all based on meshing cooperation with standard cylindrical gears with either straight (spur) or helical teeth. The angle between the transmission shafts may be 90°, less or over, the shafts may inter-sect or cross. In case involute toothing is chosen for the cylin-drical gear wheel,  all well-known advantages remain valid,  thus alignment of the transmission is considerably less critical than with bevelled transmissions, axial-pinion loads are less or absent, loading capacity is comparable or better find transmission ratios surpassing approximately 1:5 become the more attractive. In many cases less transmission steps will be possible, reducing size and cost.  Simple replacement becomes possible, without any alignment problems. Face gear transmission now may be used for primary, high load, long-life industrial applications.
