Abstract: This invention relates to a compact bath-chair support comprising a frame having a flat bottom surface for resting on top of a side of a bath. The frame has along a first side, at least one jaw downwardly extending,and fixedly or slidab-ly mounted, onto that frame, above a plane containing the flat bottom surface. At least one downwardly extending jaw is slidably mounted on the side opposite the first side, and above that plane containing the flat bottom surface. A screw or other clamps, is positioned above the plane containing the bottom surface, and connected to the jaws that are slidably mounted, for the jaws of one side to move toward and away from, the jaws on the other side, so as to act as a vise, to securely  hold the side of a bath near the top. The frame has above the bottom surface, at least one receptacle for recei-ving the shaft of a chair. Thus the weights of and on a chair and of that frame, are transferred onto the top of the side of a bath, and the jaws releasably hold the side of a bath near the top in order to maintain the flat bottom surface against that top.

Title: Method of operating an ultrasonic piezoelectric transducer and circuit arrangement for performing the method
Inventor: GETMAN IGOR
IPC: H04R1/24
Filed: 1995-09-06
Granted: 1999-06-15
Abstract: An ultrasonic piezoelectric transducer is alternatingly operated in a transmitting mode and in a receiving mode. In the transmitting mode an electrical excitation signal is applied between one or more common electrodes and one or more transmission electrodes, and in the receiving mode an electrical reception signal is collected between the one or more common electrodes and one or more reception electrodes. Moreover, in the receiving mode one or more electrodes which are not used as reception electrodes are connected via a low impedance connection with the one or more common electrodes which has the effect that in the receiving mode the reso-nance frequencies of the piezoelectric transducer are shifted to lower values so that with the same operating frequency the piezolectric transducer is in series resonance in the transmitting mode and in parallel resonance in the receiving mode. In this way, the piezoelectric transducer operates under optimum conditions with perfect frequency matching both for transmission and for reception.

Abstract: A coaxial connector is described, of the type that has a shell (14) with a tubular first portion (16) whose front mates with another connector and whose extreme rear end (64) is initially open, and which has a second portion (22) extending at a right angle to the first portion for mechanically and electrically terminating to the braiding (42A) of a coaxial cable (30). The second portion (22) of the shell forms a tubular ferrule that surrounds the cable inner insulation (40) and which is surrounded by the cable braiding. The connector includes a sleeve (46) which can slide along the cable to a position surrounding the braiding that surrounds the ferrule, so crimping of the sleeve locks the braiding between the ferrule and sleeve. The shell second portion includes first and second parts (50, 52) that extend respectively from the lower and upper sides (60, 62) of the rearward end (56) of the first shell portion, with the second part being bendable and each part forming about half of the tubular ferrule. The second part (52) extends rearwardly from the upper side of the shell first portion while lying above the mate axis (12) of the first shell portion to provide access for a soldering iron to reach into the initially open rear end of the first shell portion.

Granted: 1999-08-03
Abstract: An ink jet printer includes a printhead having a plurality of segments each having ink ejecting nozzles, each segment supplied with ink of a different characteristic. Means are provided for moving the printhead in a direction transverse to the advancing movement of a recording medium. Means are further provided for moving the printhead between two or more positions along the recording medium advance direction.

In one embodiment, a printhead has two segments, one printing in black, and the other in color. A shift mechanism is enabled to move the printhead between a black print position and a color print position. The invention contemplates alternate color printing swaths at alternate printing positions along the same printing swath, or a combination thereof.

Abstract: Playing card shuffles (10, 200, 400) having unshuffled stack holders (14, 215) which hold infeed arrays (15, 235) of playing cards. Ejectors (101, 240) are mounted adjacent an unshuffled stack holder (14, 215), which cam be stationary or movable. Cards (20, 236) are ejected and discharged from the infeed array (15, 235) at various random discharge positions. The ejectors can be mounted on a movable carriage (110). Extractors (130, 260) are advantageously used to assist in removing playing cards from the infeed array.

Title: Instrument sterilization life-span indicator
Inventor: MALCHESKY PAUL S
IPC: A61B17/00
Filed: 1995-08-16
Granted: 1999-07-13
Abstract: A pigment such as crystal violet is iatpregnated in or otherwise affixed to a translucent plastic or porous member (14, 22). The color change material changes at least one of opacity or color with repeated exposure to a fluid sterilant, such as an oxidant solution. A label (10, 24) is mounted behind the translucent plastic material and carries an indicia (12, 26). With repeated sterilizafions of the instrument, the color change material becomes progressively more translucent, allowing the indicia to be read through the translucent plastic material. When the indicia becomes visible, such as after about 7 sterilization cycles in Figure 3, the user is warned to discontinue use of the instrument, either discarding it or having it rebuilt. Rather than having a written indicia, a color scale (30) can be provided for comparison against the current color of the color change material. When the color changes to the discard color on the color scale, the user is again advised to discontinue use of or rebuild the instrument.

Title: Source traffic control method in atm network to prevent serious local congestion
Inventor: IKEDA CHINATSU
IPC: H04L47/629
Filed: 1997-05-14
Granted: 2001-07-03
Abstract: In an ATM network, a source end system is connected through multiple virtual channels to destination end systems to exchange resource management (RM) cells at periodic intervals and transmit data cells at allowed cell rates (ACRs) respectively set for the virtual channels. The source end system transmits a forward RM cell through an associated virtual channel, and determines a sum of ACR values of the virtual channels in response to receipt of a backward RM cell through the associated virtual channel and compares the sum of ACR values with a predetermined capacity of the access link. The source end system resets a current ACR value of the associated virtual channel equal to a lower-than-previous value when the sum of ACR values is in excess of the predetermined link capacity. In one embodiment, the sum of ACR values is divided by the predetermined link capacity to produce a link load value and the ACR value is reset according to the link load value.
