Title: Cross field amplifier
Inventor: CIPOLLA JOHN CHARLES
IPC: H01J25/44
Filed: 1993-04-29
Abstract: A double helix coupled vane forward wave crossed-field amplifier 10 uses individually cooled vanes 38 in the RF slow- wave circuit. Specifically, each anode vane 38, Fig. 4A is machined to create a channel 42 in the shape of a "U" on one side thereof and a vane coolant tube 24 formed in a corresponding U-shape is inserted and brazed to the machined vane. The vane assembly is then attached to the anode body of which the backwall 32 has holes 54 formed to accept the coolant tubes from each vane. Divided backwall coolant channels are brazed to the outside of the anode, thereby placing in fluid communication the coolant channels with the vane coolant tube. Accordingly, coolant is cycled through each vane tube and individual vanes of the anode are thus cooled. <IMAGE>

Title: Optical measurement of contaminants in fluids
Inventor: BRIGGS RONALD
IPC: G01N21/85
Filed: 1993-07-23
Abstract: Apparatus for measuring the concentration of a contaminant in a fluid comprises a measuring chamber, a first source of optical radiation of predetermined wavelength which is directed through the chamber, a detector to detect the transmitted radiation and a pump to supply fluid to the measuring chamber. A reference measurement is provided by periodically diverting the supplied fluid through means which either removes a contaminant which is detectable at the wavelength used, or converts an undetectable contaminant to a detectable compound. A system for detecting contaminants in water has modulated light sources at 253.7 nm (for detecting ammonia, organic and suspended matter) and at 206 nm (for detecting nitrate ions). Nitrate ions and organic matter can be removed using resin ion-exchange columns, whereas ammonia is made detectable at 253.7 nm by conversion to monochloramine on addition of chlorine.

Title: Ventilator for promoting lung function
Inventor: JONES NORMAN STEWART
IPC: A61M16/00
Filed: 1993-10-06
Abstract: The ventilator has a control system providing for semi-automatic operation in which a single complete ventilation cycle in accordance with predetermined parameters (tidal volume, durations of inhalation and exhalation phases) is initiated by operation of a trigger and is particularly useful in one-man resuscitation by CPR. The control system may require a discrete trigger operation to initiate each successive ventilation cycle or it may provide for continuous operation with timed successive cycles by holding or latching the trigger. The ventilator may be gas-powered or electrically operated or controlled. Typically, the output line (6) of a pneumatic oscillator is controlled by a diaphragm (22) held closed by a spring (36) loaded by a trigger (31) that, when operated, permits the diaphragm to open the output line. The output line pressure then acts on the diaphragm to hold the line open until output pressure falls at the termination of the inhalation cycle. <IMAGE>

IPC: H02B1/30
Filed: 1993-11-04
Abstract: A lock handle mechanism advantageously used for an electric switchboard box includes a monolithic lock handle fully foldable in a housing of the box. The lock handle (16) is mounted to the housing (1) to allow vertical turning and lateral rotation and is connected via a lock shaft (3) to a proper lock provided on the housing (1). For unlocking the switchboard box, the lock handle (16) is first turned forwards and upwards out of the housing (1) to an extended position and next rotated laterally so as to break the locking connection to the housing (1) and to allow free opening of the box. For locking the switchboard box, the lock handle (16) is first rotated back so as to restore the connection to the lock on the housing (1) and then turned down and back into the housing. The handle is provided with a pair of faces one of which abuts with a washer urged towards the handle when the handle is in the folded position and the other faces abuts with the washer when the handle is in the extended position. The lock handle (16) may be locked in the housing using a cylinder key lock mechanism (27). <IMAGE>

Title: Male incontinence sheath and applicator
Inventor: MILLS BARRIE THOMAS
IPC: A61F6/00
Filed: 1995-03-27
Abstract: A male incontinence sheath is applied by putting the sheath 10 onto the open end of a bellows 20 and placing the device on the penis 40, the bellows is compressed, the air exiting through a one-way valve, the bellows is then expanded creating a partial vacuum which draws the sheath and penis into the bellows. Air is then admitted into the bellows causing the sheath to collapse onto the penis. The bellows is then pushed towards the wearer, causing the sheath to be everted as it slides off the bellows onto the penis. A ring of adhesive 12 secures the sheath to the penis. The bellows can then be removed and discarded. Alternatively, the bellows may be reused if used together with a removable sleeve carrying the sheath. The bellows may be replaced by a pair of telescoping tubes. <IMAGE>

Title: Drive control system for battery car
Inventor: SUZUKI AKIRA
IPC: B60L15/20
Filed: 1995-05-19
Abstract: Two motor sensors are disposed at different angular positions of a motor to generate pulse signals of different phases. The motor rotational speed and direction can be detected on the basis of these two pulse signals (54). The detected motor rotational direction is checked as to whether it is the same or opposite to that determined by the shift lever (55). If opposite, the battery car is determined to be moving down a sloping road, and the motor torque is corrected so that the battery car can be stopped on condition that the accelerator pedal is slightly depressed. After that, when the accelerator pedal is further depressed ordinary drive control is executed. Therefore, the start and slow speed driving on a sloping road can be facilitated, without any skill, thus lightening the burden on the driver. <IMAGE>
