Title: Injection of ions into an ion trap
Inventor: FRANZEN JOCHEN
IPC: H01J49/04
Filed: 1997-07-07
Abstract: A method for injection of externally generated ions into an RF quadrupole ion trap 5-8 consists of separating the ions into ion packages within an electrical travelling wave field 2 operated at the frequency of the drive voltage for the ion trap, or at an integral fraction of the same, transporting the ion packages by the travelling wave field to the ion trap, and injecting the ion packages into the ion trap with a selected velocity and at a selected phase angle. A slowing-down path at the end of the travelling field allows ions of a greater mass to be injected somewhat earlier than light ions, whereby the simultaneous capture of ions of different masses is possible. The electrical travelling wave field 2 is provided by a stack of mutually insulated apertured diaphragms, each diaphragm being supplied with one phase of a multiphase alternating voltage.

Title: Call screening
Inventor: HOLIDAY II MATTHEW R
IPC: H04M3/51
Filed: 1998-12-11
Abstract: A system and method that controls calls, such as telephone solicitations, by a calling party (12) to a called party (14). A switch (16) receives a call from the calling party and marks the call to identify it as a telephone solicitation. Such marking can be performed in various ways, such as altering a forward call indicator of an IAM message if the switch is using an ISUP procedure, or providing a station type with information digits used in multi-frequency signalling. After the call has been marked, it can then be identified by a switch (18) serving the called party as a telephone solicitation. Once identified, the switch then analyses a profile for the called party and determines how to complete the call. For example, if the profile indicates that the called party does not want to receive telephone solicitations, the call will not be completed to the called party, but instead will receive alternate treatment.

Title: A holding circuit for a vending machine incorporating a money/card tester
Inventor: BUSCHMANN HORST
IPC: G07F7/08
Filed: 1998-12-11
Abstract: A holding circuit for a vending machine incorporating a money/card tester 24, and having a control circuit 14 with a parallel interface which processes a vend only when signals are simultaneously received from both a user operated selection switch 26, for choosing the vend item, and the tester, upon validation of the deposited tender, comprises a holding relay 42 which provides a continuous signal to the control circuit once the selection button has been pressed, and a means of sending a reset signal 48, 50 to the holding relay from the tester or the control circuit. The tester contains a microprocessor 16, the control circuit comprises a sales relay 28 for determining the vend price, and the coupling between the various elements may be via opto-couplers 22, 32. Preferably a time function element 38, controlled by the control circuit, is provided and resets the holding relay after a pre-set time. An AND gate (60, Figure 2) may also be provided so that signals from both the time function element and from the control circuit signifying that a vend has occurred (40, Figure 2) are required to reset the holding relay. The holding circuit thus takes account of the time delay, which may be several seconds, necessary for the testing of charge or smart cards and hence ensures a vend even if the operator does not depress the selection switch for the whole of this time period.
