Abstract: ABSTRACT      A torque multiplier subsea tool for setting a seal between a casing hanger and a subsea wellhead includes a mandrel having a sun gear with axial elongate teeth.  An outer barrel is disposed around the mandrel forming an annulus therebetween.  A planetary gear assembly is disposed in the annulus between the barrel and the sun gear to transmit to the barrel a torque which is higher in magnitude than that applied to the mandrel.  A connector body disposed around the mandrel, below the planetary gear assembly, includes radially movable dogs for engaging the casing hanger.          The barrel engages the sealing assembly and transmits the in-creased torque thereto to advance the sealing assembly downwards and to set the seal.  The mandrel advances downwards with the sealing assembly and releases the dogs from the casing hanger.        An emergency release mechanism is provided to advance the mandrel downwards to release the dogs in the event such downward movement is prevented during normal seal setting operation.

Abstract: Combination Compact Microwave Oven and Ventilator System ABSTRACT      A combination compact microwave oven incorporates ventilator and cooling systems into a unitized structure which may typically be installed on a wall above a conventional electric or gas range.  A ventilator assembly including centrifugal fans at the top backward edge is rotatable adjustable for different installations.  The space under an outer housing is utilized as an exhaust duct containing a filter means through which exhaust gas can be discharged if there is no external vent available.  Air is taken into the cooling system from above through an opening where relatively cool air is expected to be available and is passed through separate air flow channels for efficient cooling of individual areas and components.

Abstract: ABSTRACT OF THE DISCLOSURE           By means of an arrangement according to the invention an automatic recommencing of the ignition function of an internal combustion engine with a computer controlled ignition system is achieved.  The system includes, inter alia, an oscillator which occasionally can stop working.  An RC-circuit is charged by ignition pulses supplied by the micro-computer and is discharged by possible failure of these pulses.  A sensing circuit influenced by the RC-circuit thereby supplies a so-called reset pulse to the computer which then recommences the supply of ignition pulses.

Abstract: ABSTRACT:         In order to reduce the likelihood of incorrect states being transferred from one cross-coupled transistor pair to the next in a frequency divider which comprises at least two such pairs (6a, 7a and 8a, 9a) which are ener-gized alternately by means of a switchable current source arrangement (5) and which are inter-coupled to form a cyclic arrangement by means of data transfer transistors (6b, 7b, 8b and 9b) energized from the same outputs (22, 23) of the current source arrangement, the transistors employed are of the insulated gate field effect type.  If desired the channel width-to-length ratios of the pair transistors (6a, 7a, 8a, 9a) may be chosen to be different to the corresponding ratios for the data transfer transis-tors (6b, 7b, 8b, 9b) in order to improve either the high-frequency or the low frequency performance in accor-dance with the sign of the difference.

Abstract: ABSTRACT OF THE DISCLOSURE           For measurement of gas pressure a gas-friction vacuum meter is used  in whose measuring head a rotating body is suspen-ded in a magnetic field contact-free between electromagnetic drive coils.   The rotating body is set in motion with the aid of the drive coils and maintained at a rotational speed above a preset minimum rotational speed.  The speed reduction of the rotating body occurring on account of gas friction is continually or intermittently balanced with current flows from a three-phase generator to the drive coils.   In the measuring head rotational speed sensors are arranged and positioned, which detect and respond to the rotational frequency of the rotating body, and further transmit output signals to an electronic analyzer unit, which determines the pressure from the timely change of the rotation frequency.   In order to increase the pressure range for which the apparatus may be accurately used further, the analyzer unit receives a temperature signal, which correlates with the tempera-ture of the gas surrounding the rotational body, in such a way, that the pressure measurement is corrected for the influence of heat transferred to the gas during operation of the rotating body.

Abstract: ABSTRACT      "PROCESS FOR THE PRODUCTION OF FEEDSTUFFS"        Feedstuffs for ruminants comprising a water insoluble salt of an edible higher fatty acid and optionally a further nutritional material, especially a proteinaceous feedstuff such as soya bean meal, are produced by forming a mixture of a basic oxide such as calcium oxide, a fatty acid, and optionally the further nutritional material under conditions such that the nutritional material when present is impregnated with fatty acid, adding water to the mixture, and allowing the oxide to react with the acid to form the water insoluble salt.  The still hot reacting mixture is spread out so that sufficient water evaporates spontaneously to give a friable product.          The process may be operated continuously.

The method comprises selectively arranging indi-vidual characters of data messages of varying bit rates in real time in a multiframe matrix and transmitting the data messages at a defined bit rate to individual receiver loca-tions where the data messages addressed to the individual receiver locations are decoded and displayed.  The trans-mission method allows data messages of varying bit rates to be transmitted at a single defined bit rate to the receiver locations.  At the receiver locations, the data messages are extracted from the matrix and regenerated.  The data transmission method allows for downstream insertion of additional data and is highly tolerant of burst errors.          A system for transmitting data using the method is also described.

Abstract: ABSTRACT OF THE DISCLOSURE           Each gripper chain assembly is driven by its own headshaft.  The headshafts rotate in opposite senses and are powered from a motor/reducer combination.  A sheave on the output shaft of the reducer is coupled by one endless belt with a sheave on one of the headshafts, and it is also coupled with a sheave on the other of the headshafts by another end-less belt.  The one belt is in a non-twisted configuration so that the sheave on the one headshaft rotates in the same sense as the reducer output shaft. The other belt is twisted into a figure eight configuration so that the sheave on the other headshaft rotates in the opposite sense.  The two head-shafts therefore provide the desired counter-rotation of the two gripper chain assemblies.  The motor reducer is mounted on a base plate which is adjustably positionable on the con-veyor's frame so as to enable the drive to be adjusted when-ever the spacing distance between the two gripper chain assemblies is adjusted for conveying a different sized article. A separator is mounted on the base plate to maintain separation of the twisted drive belt where it crosses itself.  In one em-bodiment the base plate is secured by fasteners, but is adjust-ably positionable by loosening the fasteners, performing the adjustment, and then retightening the fasteners.  In another embodiment the base plate is mounted on guides and biased to maintain tension in the endless belts while allowing its automatic tracking of gripper chain assemblies' adjustment without the need to loosen and retighten fasteners.  The bias may be provided by a counterweight or by springs.
