Title: Keyed insert plate for curved rotary lobe pump chamber walls
Inventor: DODD IAN
IPC: F04C2/08
Filed: 1995-09-06
Abstract: A rotary lobe pump comprises a pump housing defining an obround pump chamber and a pair of lobe rotors in the pump chamber. The rotors are mounted on rotatable shafts which are connected by timing gears such that the rotors rotate at a same speed but in a reverse direction and with the lobes thereof interlocking in such a way that the rotors cause a fluid to displace through the chamber. The pump chamber is defined in the pump housing by opposed front and rear end walls which are perpendicular to the axes of the rotors and by arcuate side walls with which the rotors make sealing contact and which gradually wear out thereby reducing the tightness of the seal and thus the pumping efficiency of the rotary lobe pump. The rear end wall includes two removable end wear plates which each include a rearwardly projecting key engaged in a corresponding keyway defined in the pump housing with bolts extending from outside of the housing inwardly towards the end wear plates and engaging the keys thereof for securing the end wear plates to the housing. The arcuate side walls take the form of removable curved wear plates which are each semi-cylindrical in shape and which each include an outwardly directed radial curved key which is engaged in a corresponding curved keyway defined in the housing. Bolts which extend through the housing into the keys retain the curved wear plates in position in the pump chamber. The rear ends of the curved wear plates are supported by the peripheral edges of the end wear plates.

Title: Detection of goods on the bottom rack of a cart
Inventor: SCHRADE CHESTER R
IPC: G08B13/14
Filed: 1996-05-02
Abstract: The inadvertent or fraudulent transport of goods on the bottom tray of a shopping cart passed a check out stand is detected by providing a first transmitter/receiver element on one side of an alleyway and a second transmitter/receiver element on the other side of the alleyway.  The first element has a series of transmitters arranged in a top row of three and a second row of two transmitters with the top row above the bottom rail of the cart and the second row at the height of the bottom rail of the cart. A similar array of receivers is arranged on the second element.  In response to a condition in which all of the receivers are blocked, two transmitters which are optically independent and located below the bottom rail generate a beam across the alleyway to two receivers symmetrical to the transmitters at the first element.  An alarm condition indicating the presence of goods is generated in response to the receipt of light by both of the receivers of the first element. The system, by using the above   pattern,   optically distinguishes between goods on the bottom rack of a shopping cart and other objects passing through the alleyway.

IPC: H04B10/299
Filed: 1996-09-19
Abstract: The optical delay unit (ODL) introduces a programmable delay of an optical signal on an optical signalpath. The delay of the optical signal is realised by converting the incoming optical signal (IN) into an electrical signal, then delaying the electrical signal, using electronic devices in an electrical delay unit (ELDL), and finally converting the electrical signal into an optical signal. Theelectrical delay is controlled by an operator sending control data (A) via a control interface (Cl) to the electrical delay unit (ELDL). A first use relates to the testing of the normal operation and/or performance of an optical network for different optical line lengths. A second use relates to the inclusion of thedelay unit in an optical line emulator (OLE) wherein this optical delay unit (ODL) is coupled to an optical attenuator (ATT) which is also controlled by an operator sending control data (B) via the control interface (Cl) and a power control unit (PCU). This optical line emulator (OLE) simulates an optical line by simulating the delay and the attenuation of an optical signal on the optical signal path on which the optical signal is transmitted.
