Abstract: The present invention is that of an improved device for carrying a weapon. The present invention provides concealed carrying of a weapon, preferably a handgun, by a law enforcement officer or the like. The handgun is supported on the upper back of the wearer, preferably between the wearer's shoulder blades. The handgun is held in a holster having a body that is formed to match the contour of the gun. The holster includes a sheath of flexible material extending across the upper back of the wearer. The sheath is held in place by a pair of shoulder straps and a pair of armpit straps.

Abstract: A combined metal and plastic standoff for supporting a circuit board in fixed spatial relationship with another element comprises a rigid plastic body of appreciable length to produce the standoff effect and a metal retaining member integrally mounted on the plastic body at an operative end thereof. The metal retaining member has main and retaining portions, the main portion being fixedly disposed within the plastic body and the retaining portion extending outwardly from the plastic body having a resilient reverse bend segment, and being adapted for engagement with the circuit board or other element by an essentially longitudinal motion of the standoff along the axis of the body length to physically secure the circuit board or other element to the plastic body adjacent to the operative end.

Abstract: This invention is concerned with a machine in the nature of a scrubber for removing dirt, grime, etc. from a surface to be cleaned and includes a mobile machine with a scrub brush mounted for rotation about a generally vertical axis with a housing therefor which is pivotally mounted and concentric with the scrub brush drive. The brush, brush drive, brush housing and squeegees which are mounted on the brush housing, also make up a brush head assembly that is raised and lowered as a unit.

Abstract: A method of control and a control circuit for use in connecting all or sub-parts of a battery supply to a battery driven motor includes relays connected between a motor and each sub-part of a battery supply; a timer having a predetermined time period and which changes its output condition at the end of each time period; a motor speed selector for selecting either full motor speed or a portion thereof; and a switch arrangement which interconnects the relays, timer and motor speed selector. The switch arrangement provides for a first sub-part of the battery supply to be connected to the motor when the selector is in a less than full speed position and when the timer has one output condition. A second sub-part of the battery supply is connected to the motor when the selector is in a less than full speed position and the timer has a second output condition. The relays connect the full battery supply to the motor when the selector is in a full speed position.

Abstract: A mobile sweeping machine having separate hydraulic motors for driving a main brush, a propulsion wheel, and a curb brush and a suction blower; a constant speed power source that through a mechanical drive connection drive two variable speed displacement pumps and a fixed displacement pump; one of the variable displacement pumps being fluidly connected to the propulsion wheel motor; the other variable displacement pump being fluidly connected to the main brush motor; and the fixed displacement pump being fluidly connected to a valve for operating the cylinder for varying the downward pressure on the main brush, and to a valve for selectively applying fluid to the cylinder for operating the sweeper hopper, and supplying fluid to drive the curb brush and suction blower motors. A manual control is provided for operating the main brush hydraulic motor to discontinue the rotation of the main brush, to drive the main brush at a low brush speed, and to drive the main brush at a high brush speed. Brush tuft mounting annular flanges are tack welded to a brush tube at spaced locations around the inner peripheries of the flanges which are axially spaced from one another on the brush tube.
