Title: Method for removal of monovalent ions from zns04 electrolyte by electrodialysis
Inventor: BALL DONALD L
IPC: C25C1/16
Filed: 1987-04-07
Abstract: Monovalent ions, especially chloride, fluoride and thallium, are efficiently removed from ZnSO4 electrolyte by electrodialysis using alternating monovalent anion permselective membranes and cation exchange membranes or monovalent cation permselective membranes. Electrodialysis is carried out under turbulent flow conditions, at up to 60 DEG C, a differential membrane pressure of less than 150 kPa, a current density of 10 to 500 A/m<2>, and a pH of less than 5.5. Where both chloride and fluoride are removed a pH of 3.5 to 5.5 is maintained. Deposition of manganese and zinc on the electrodes is minimized by at least one of a number of means including arranging the membranes such that the end membranes are monovalent anion permselective; selecting a large electrode rinse flow; adding a small amount of soluble antimony and/or cobalt to the rinse flow; and using a cathode made of a material that promotes hydrogen evolution over zinc deposition. The electrode compartments are preferably rinsed with a 0.1 to 1.0 M Na2SO4 solution at pH 0 to 4.

Title: Synchronisation checking
Inventor: JELLEMA BART
IPC: H04L5/14
Filed: 1996-07-19
Granted: 2000-09-13
Abstract: In a duplex communications system with asynchronous exchange of messages between two stations, such as between a service switching point SSP and a service control point SCP in an Intelligent Network, each message sent from a station includes a sequentially assigned number indicated by a sending ID parameter SID and also includes a receiving parameter LPID indicating the number of the most recent message received from the other station. For example, the SCP sends a message with SID= 1*,LPID = 1 in response to message number 1 from the SSP. If the SSP sends a message SID=3,LPID=1* before receiving a message SID=2*,LPID=2 sent by the SCP in response to the previous message (SID=2,LPID=1*) sent by the SSP, the SSP can detect such message "crossing" (ie. the stations are effectively out of synchronisation) because the LPID =2 parameter indicates a response to message SID =2, rather than message SID =3, from the SSP. The SSP may then ignore message SID=2*,LPID=2 from the SCP and await the SCP's response SID=3*,LPID=3 to the SSP's most recent message (SID =3,LPID = 1*). Because of the sequential numbering, it can also be detected when a message has been lost during transmission (Fig.6).

Title: End fire commutated linear antenna array - for simulated Doppler ground beacon guidance, with each element giving same radiation pattern
IPC: H01Q/
Filed: 1973-12-24
Granted: 1978-02-20
Abstract: The array operates as an entire array of n elements in which n-1 elements are successively excited in accordance with a commutation (scan) programme. As each element is excited, the immediately adjacent element to the rear (opposite the radiation direction) has a base loading circuit activated such that it acts as a short circuit and therefore the element itself acts as a reflector in cooperation with the excited element. At the same time all other elements are provided with base loadings so that they are open circuited and appear transparent for radiation purposes. A dummy parasite reflector behind the first element of the array (not commutated) has a fixed short-circuit loading at its base. Thus the radiation pattern is the same in the forward direction during the successive excitation of the commutated elements.
