Abstract: A protective enclosure fabricated from a clear, flexible, plastic material that, in the event of an emergency, is easily positionable over the head and upper body of a wearer to protect the wearer from the adverse effects of a contaminated environment, such as that filled with smoke or similar noxious fumes. The top of the enclosure is sealed by a reinforced, relatively stiff closure member. Accordingly, an airspace containing a reserve air supply from which the wearer may breathe is created around the wearer's head. The bottom of the enclosure contains a fastener by which the enclosure may be securely tightened around the waist of the wearer. Each side of the enclosure includes an arm port through which the wearer's arms may extend. The arm ports are interfaced with an elastic material which is adapted to form an airtight seal around the wearer's arms when the arms are inserted therethrough.

Abstract: A unique pipe configuration including a magazine in which a supply of tobacco may be stored, so that a smoker will not be required to waste excess time and effort to continuously replenish the pipe with new tobacco when a plug of tobacco therein has been exhausted. A desired amount of the tobacco supply is moved from the magazine into a hollow cutting and smoking chamber by a manually operated piston. A plug of tobacco is cut from the supply thereof by a hollow tobacco cutter and transport device having a cutting surface formed at one end thereof. The cutter and transport device is adapted to ride through the cutting and smoking chamber so as to cut off and move the tobacco plug through the cutting and smoking chamber to a particular location thereof wherein the tobacco plug is smoked. The pipe location at which the tobacco plug is smoked is separated and spaced apart from the communication of the pipe stem with the cutting and smoking chamber.

Abstract: An automated system for controlling the curing process of structures formed of fiber-reinforced composite material and the like in an autoclave is disclosed. The system uses sensors to monitor autoclave pressure, ambient and structure surface temperature, and structure viscosity during the cure cycle. Real time measurements are taken for each of these parameters, and the measured values are compared with predetermined optimum values which themselves change as the curing cycle progresses. The results of the comparisons are used to control the application of temperature and pressure in the autoclave to achieve the desired visco-elastic states of the structure which continually change as the curing process progresses. The viscosity data are obtained through measurements of attenuation of an ultrasonic wave in the composite material of the structure. It was found that the attenuation is directly related to the viscosity of the structure.

Abstract: A container assembly is disclosed which incorporates a chemical indicator normally hermetically sealed from the ambient atmosphere, but exposed to the atmosphere upon opening of the container assembly. The indicator is adapted for changing appearance, either color or granule or crystal form, upon exposure to moisture or oxygen. The indicator is either located in the interior of a hermetically sealed container, or is sealed in a frangible envelope which is operatively associated with a closure member of the container and is ruptured upon opening, or attempted opening of the container.

Abstract: A dry dock having flotation chambers on two opposite sides of the load-carrying platform is submerged by flooding the flotation chambers. A reversible air pump is used to raise the dry dock by first blowing water out of the chambers then sucking water from the platform into the chambers and then again blowing water out of the chambers. The structure of the dry dock allows it to be used also as a submergible barge.

Abstract: A linear rotary bearing is disclosed which includes bearing race adapted to be mounted on a substantially cylindrical shaft in spaced concentric relationship with the shaft. A ball retainer disposed between the race and the shaft defines a plurality of longitudinally disposed ball channels. An outer housing is mounted on the exterior of the race. A plurality of longitudinally disposed ball return channels are formed between the housing and the race. An annular chamber is formed in each end of the bearing between the race and the housing. Balls placed into the bearing do not entirely fill the space available for the balls in the ball channels, ball return channels, and annular chambers. During linear motion of the bearing relative to the shaft the balls behave substantially like a fluid in the sense that they randomly move from the annular chambers into the ball channels and ball return channels to fill available space. Approximately 2.

Abstract: A protective enclosure fabricated from a clear, flexible, plastic material that, in the event of an emergency, is easily positionable over at least the head of a wearer to protect the wearer from the adverse effects of a contaminated environment, such as that filled with smoke or similar noxious fumes.The enclosure is provided with an opened side for receiving therethrough the head of the wearer. The ends of the enclosure which define the opened side thereof are structured so as to generally conform to the shape of a human chest. The aforementioned ends which define the opened side are provided with fastening means by which the opened side may, be secured to the chest of the wearer in order to form an airtight fit therebetween and thereby close the opened end against the chest and around the neck of the wearer.

Abstract: A power transmission and brake assembly for motorcycles and like vehicles wherein a chain driven rear wheel is mounted on a swing arm, is disclosed. An idle sprocket and brake assembly including a first and a second idle sprocket and a brake member such as a brake disk is mounted to rotate about a pivot axle of the swing arm. First and second endless chains interconnect the idle sprocket assembly respectively with an output shaft mounted drive sprocket and a rear wheel sprocket. A brake engaging member, such as a pair of hydraulically actuated brake calipers, is fixedly connected directly or indirectly to the swing arm. The brake engaging member frictionally engages the brake member whenever braking of the chain driven wheel is desired. As a result, a force arises during braking which tends to push the rear wheel downward towards the road surface, and thereby increases the traction of the rear wheel.

Abstract: A gearless speed and torque converter is disclosed wherein a first member or input member fixedly mounted to a rotatable input shaft has an Archimedes spiral groove-bearing surface. A second member or output member fixedly mounted to a rotatable output shaft has an Archimedes spiral groove-bearing surface which is complementary to the spiral groove-bearing surface of the input member and is disposed adjacent thereto. The Archimedes spiral groove of the output member has a pitch different from the pitch of the Archimedes spiral groove of the input member. The input shaft and the output shaft are coaxially mounted relative to one another. A plurality of balls are disposed between the respective spiral grooves and are held therein solely by virtue of being captured in the intersecting spaces of the spiral grooves. During rotation of the input member, the balls move on a spiral track at a rotational speed which is an average of the rotational speeds of the input and output members.

Abstract: This invention relates to a process of automatic drilling with an in-hole motor particularly of the turbine type. The invention relates to apparatus and process by which the draw works responsive to a signal generated by an in-hole tachometer in the form of a train of pulses of period responsive to the rpm of the motor is sensed by a pressure transducer which generates a signal which is responsive to the rpm of the motor telemetrically in the form of the train of pulses. The signal is converted into a pressure applied to the brake of the draw works driven to hold the tension on the drilling lines and thus holds the rpm of the motor substantially consistant. In the best mode disclosed, this is accomplished by producing an electrical signal responsive to the train of pulses and storing said signal between pulses and generating a pneumatic pressure responsive to the stored signal and applying a force to said driver responsive to said last named pressure.

Unlike conventional golf training or practice apparatus, the photodetectors of the present invention are responsive to ambient light. The photodetectors are disposed in parallel alignment with one another, so as to receive respective horizontal and parallel beams of light, whereby to define the measuring zone therebetween.
