It is known that olefins can be prepared from steam and hydrocarbons such as natural gas or oil. Generally, such processes are operated at high temperatures and high pressures, with high ratios of steam to hydrocarbon. A prior process, described in U.S. Pat. No. 4,438,233 to Mardirosian et al. involves the use of superheated steam in a downward direction at temperatures ranging from F. to F., and at pressures in the range from 800 to 5000 psia. However, Mardirosian notes that the process is unsuitable for use with cold hydrocarbon streams. He also notes that the process is more convenient and economical when the hydrocarbon feed is operated in the vapor phase. However, in such a vapor phase operation, higher temperatures are generally required.
According to a variety of prior processes, the temperature may be varied within a certain range in order to avoid condensation of the hydrocarbon feed material. One such process is shown in U.S. Pat. No. 2,659,882 to Dutcher et al. In that process, steam is expanded in a first stage to 300 psi and superheated to F. In a second stage, the pressure is reduced to F. and 5.0 lb. per square inch, and the temperature is reduced to F. to F. by indirect heat exchange with water. The temperature in the second stage is further reduced to about F. by direct heat exchange with water. Finally, the vapor mixture is expanded and quenched to form a liquid by passing the mixture through a water bath. The product normally contains higher hydrocarbons, and the quenching is preferably conducted with water. The Dutcher patent concludes with the statement that “the system so described can be operated with a wide range of operating conditions including temperatures for the hydrocarbon vapors of F. to F., or under subcooling of some F. to about

Disclosing truth: personal narratives and mental health.
Narrative works are an important medium for conveying insights into the self. This paper explores the ways in which mental health professionals engage with personal narratives. The association between personal narratives and therapeutic change is considered in the light of the potential of narrative forms to uncover and express deeply held emotions. The theme of trust between clinicians and their patients is seen to be paramount to the unfolding of this therapeutic relationship. Furthermore, clinicians utilising personal narratives need to be aware of their own as well as their patients’ roles in the process. This paper discusses the significance of biographical and social context and posits some implications for practice in psychiatry.Characteristics of patients with amyotrophic lateral sclerosis at a university hospital.
We investigated the clinical and laboratory characteristics of patients with amyotrophic lateral sclerosis (ALS) at a university hospital in Japan. The medical records of 65 patients with ALS and possible or probable ALS (ALSp) were reviewed. The predominant localization of the initial symptom and the initial severity of the disease (evaluated according to the ALS functional rating scale (ALSFRS)) were also studied. The mean age was 64.0 years, and the female-to-male ratio was 4.0:1. The mean duration of disease at initial evaluation was 1.5 years. The majority of the patients (55, 84.6%) were initially diagnosed as having ALSp. During the disease duration, the initial symptoms of six patients changed from limb to bulbar. Of the 65 patients, 32 (48.5%) showed bulbar symptoms at the onset. The number of patients with involvement of the paretic extremities at the onset was significantly higher in the bulbar onset group (36, 100%) than in the limb onset group (16, 13.3%; p
