Abstract: A camera includes a chamber for containing a film cartridge having a rotatable film spool with external engagement access to allow rotation of the spool. The chamber is closed by a lighttight door having a cavity including a status indicator member for determining the status of a contained film cartridge. The status indicator member is attached a cartridge engagement member which is rotatable with the cartridge film spool. The status indicator member includes a display disk for indicating the status of said cartridge based on the rotational position of said spool which is visible through an opening in the chamber door.

Abstract: A one-time-use camera comprises a resistive heating element positioned to apply sufficient heat to a critical component of the camera, such as a plastic taking lens, to permanently damage the component when a battery in the camera is connected to the heating element, and a normally open switch which is closed to connect the battery and the heating element after the last available frame of a filmstrip in the camera has been exposed.

Abstract: The present invention relates to a novel method for treating a mammal suffering from or susceptible to schizophrenia and schizophreniform diseases.

Abstract: An apparatus including a camera body adapted to receive a thrust film cartridge, a thrust spindle for engagedly receiving a thrust cartridge spool, a take-up spool, and a mechanism for simultaneously driving both the thrust spindle and the take-up spool in an advance direction such that a surface speed of the take-up spool is faster than a surface speed of film being thrust from the thrust cartridge. A first one-way clutch is operatively positioned between a drive mechanism and the thrust spindle, and a second one-way clutch is operatively positioned between the drive mechanism and the take-up spool. A rewind spindle engagedly receives the thrust cartridge spool, and a rewind mechanism drives the rewind spindle in a rewind direction. A third clutch is operatively positioned between the rewind knob and the rewind spindle.

Abstract: An exothermic gas phase reaction, especially synthesis of ammonia or methanol, is carried out by passing the reactant gas over a catalyst in a first zone in heat exchange with a coolant and then in a second, adiabatic zone and then passing reacted gas directly to a heat recovery zone. Such a sequence of zones affords a higher output of product and better heat recovery than in many previously used sequences, especially when the heat available from the cooled zone is used to pre-heat reactant gas and the heat removed from the gas leaving the adiabatic zone is used in high-grade recoveries such as high pressure steam generation.

Abstract: In a reactor suitable for gas-phase catalytic exothermic synthesis, in particular of ammonia or methanol the synthesis gas is reacted in an upstream adiabatic catalytic zone, is cooled in a heat exchanger and then reacted further in a downstream catalytic zone, whereafter preferably it is cooled again, suitably in a boiler or feed water heater, and reacted further in a further catalytic zone. The gas flow through the catalyst is mainly in an axial direction and the pressure drop is kept low by disposing the catalyst in each zone in a plurality of beds fed in parallel from an inlet header and delivered in parallel into an outlet header. The beds may be separately removable from the reactor to facilitate catalyst charging and discharging.
