Abstract: A novel gasoline additive is described comprising a mixture of methanol, iso-propanol, methyl t-butyl ether and, optionally, a C 5-  isomerate, typically in amounts of, per 100 parts by weight of additive, from about 5 to about 90 parts by weight methanol, from about 3 to about 35 parts by weight iso-propanol, from about 3 to about 35 parts by weight mthyl t-butyl ether, and from 0 to 35 parts by weight of C 5 - isomerate. A process is described for producing such an additive from natural gas streams by isomerising n-butane component thereof to iso-butane, dehydrogenating propane component of the natural gas stream to propylene and iso-butane formed by isomerisation of n-butane to iso-butene respectively, converting resulting propylene to iso-propanol, etherifying resulting iso-butene with methanol to form methyl t-butyl ether, and blending resulting iso-propanol and methyl t-butyl ether with methanol, and optionally with a C 5-  isomerate formed by isomerising C 5  and heavier hydrocarbons present in the natural gas stream, to form the additive.

Abstract: A communication system comprises several transmission bus segments (A...G) to which data stations (ST) are attached. Node units (1...7) are provided for interconnecting the bus segments which are selectively activated in a predetermined sequence for authorizing message transmission by attached data stations according to any given access protocol. Thus, only small groups of stations contend for access, but all messages are distributed over the whole network. 
     Activation of a bus segment is effected by an authorization message from an assigned node unit. A token message is used to pass the status enabling a node to activate its assigned bus segment, sequentially through all nodes of the network. 
     Each node unit comprises a control unit (17) for sending and receiving token messages and segment activation messages, and further comprises unidirectional amplifier means and switches (11) for establishing a connection between two associated bus segments selectively in either direction.

Abstract: A heat contact fixing device for fixing powder images on a receiving material comprises a heater element (11) in a rotatable drum. A control circuit controls the energy supplied to the heater element (11) in dependence upon the temperature detected by a temperature-sensitive element (24,31,50). A first section of the control circuit, comprising the temperature-sensitive element, is mounted for rotation with the drum, while a second section is mounted so as not to rotate with the drum. The sections are interconnected by sliding contacts (21,22; 33,34; 43,46). The temperature-sensitive element is the determining element for a value of a signal for measurement generated by the first section. The dynamic impedance of the first section of the control circuit for the signal for measurement is high with respect to the impedance of the sliding contacts for the signal for measurement.

Abstract: The production of improved photoresponsive amorphous alloys and devices, such as photovoltaic, photoreceptive devices and the like; having improved wavelength threshold characteristics, photoconductivity and structural stability is made possible by adding one or more band gap increasing elements to the alloys and devices. The element or elements are added at least to a portion of the active photoresponsive regions of amorphous silicon devices. One such element is oxygen which increases the photoconductivity and stability of such alloys over that of materials without the element incorporated therein. Other elements such as nitrogen and carbon can also be used to widen the band gap in order to improve the photoresponse and conductivity of the alloys. The elements are concurrently combined and deposited as amorphous alloys by vapor deposition, sputtering or glow discharge decomposition. A density of states reducing element such as hydrogen or fluorine, alone or in combination, allows the band gap increasing element(s) to be added to the alloy to adjust the band gap without reducing the electronic qualities of the alloy. The reducing element(s) can be added during deposition of the alloy or following deposition. The addition of increasing element(s) to the alloys increases the band gap to a widened utilization width for a particular device to increase the photoabsorption efficiency and to thus enhance the device photoresponse. The element(s) can be added in varying amounts, in discrete layers or in substantially constant amounts in the alloys and devices.

Abstract: ln radio communications receivers for use on frequency hopping radio communications networks, the received signal in each hop period is analysed and assigned a quality value. If more than one signal is present during the hop period it is determined that more than one network has changed to the same frequency. Similarly if the received signal is out of synchronism it is determined that more than one network has changed to the same frequency. When more than one network has changed to the same frequency, the received signal is not output by the receiver but is replaced by an earlier (or later) received signal.

Abstract: A lateral acceleration control method for a missile permits short response times to commands even of great amplitude. It comprises the association of an aerodynamic control system having large lateral acceleration capability, called PAF, with a force control system close to the center of gravity, having a moderate lateral acceleration capability, but with very short response time, called PIF. The overall response to a command includes the usual response of the aerodynamic automatic pilot to which there is added the response from the force control system, such that in the presence of a constant order, after a delay equal to the response time of the PAF, the PIF is entirely available for a new action.

Abstract: The performance of a track-following servo system for a disk file is improved by the feeding forward of a prediction of track eccentricity into the normal feedback control loop. The eccentricity related function is derived by combining functions of the position error signal (PES) and of the input signal (30) to the head position actuator (26) during at least one revolution of the disk. The eccentricity function is stored (37) and then fed forward to the actuator (26) during a subsequent revolution of the disk. The eccentricity function may be a track shape position signal formed from the difference (34) of the PES and the double time integral (31) of the actuator current (30). Alternatively it may be an actuator current profile formed from the difference between the actual current (160) and the double time derivative (156) of the PES.
