Abstract: Compressor controls in a compressed gas system provide a variable frequency controlled refrigerant compressor in a dehydrator for compressed air or other gases. The system detects changes in a demand on the pneumatic air supply by monitoring a pressure of a refrigerant system associated with the air supply. Based on the changes in the refrigerant system pressure, a motor speed controller generates and sends a control signal to the variable speed compressor to adjust the speed of the variable speed compressor based on the demand in the air supply.

Abstract: The present invention provides a variable frequency controlled refrigerant compressor in a dehydrator for compressed air or other cases. In particular, the present invention detects changes in a demand on the pneumatic air supply by monitoring a pressure of a refrigerant system associated with the air supply. Based on the changes in the refrigerant system pressure, a motor speed controller generates and sends a control signal to the variable speed compressor to adjust the speed of the variable speed compressor based on the demand in the air supply.

Abstract: A device (10) for rapid vascular drug delivery, particularly through the adult sternum or the pediatric tibia, incorporates a cylindrical syringe body (12), fitted with a needle (14). The syringe body is held in a cylindrical main housing (16) having a front barrel (18) with an orifice (20) through which the needle (14) may be extended. A cylindrical actuation handle (22) fits over end (24) of the main housing (16) for sliding movement along the main housing. A syringe plunger (26) contacts drive plunger (28) and extends into the syringe body (12) from end (30) to confine liquid medication (32) in the syringe body (12). A main spring (34) extends between the drive plunger (28) and the actuation handle (22) to bias the actuation handle (22) in its extended position. A needle return spring (38) extends between the front barrel (18) and the syringe body (12) to bias the needle to its retracted position.

Abstract: A laptop computer (10) with a tiltable and swivelable display (12) is connected to case (29) by a pivot mechanism (20) and a swivel mechanism (33). In the pivot mechanism (20), a first pivot (22) connects display (12) to a pivot plate (50), and the second pivot (24) connects the pivot plate (50) to base (32) of the display (12). The first pivot (22) consists of a pair of pivot pins (52) on each end of the pivot plate (50). The second pivot (24) consists of split pivot pins (54) at each end of the pivot plate (50). The pivot pins (54) and inboard shafts (58) are fastened together and inboard shafts (58) rotate within outboard shafts (56). The outboard shafts (56) and the inboard shafts (58) are surrounded by clutch springs (60), which are connected so that the clutches are in their free rotating direction, i.e.

Abstract: A rocket motor is disclosed which employs a Class 1.1 detonatable composition which is both a propellant and explosive. One grain design is configured to give a high boost acceleration during the burning phase of a perforated portion of the grain. The internally burning grain subsequently changes to an end-burning grain which provides a sustaining thrust burning period. The rocket motor flies to target with the burning surface progressing towards the head end. The rocket burns to target, but the design always provides some remaining propellant which serves as the warhead explosive on impact with the target. Detonator means cause the remaining unburned propellant to denonate at target impact or prior to target impact. This rocket motor design does not provide for separation between the warhead and the motor case. Therefore, the complete rocket motor travels to the target area.
