IPC: B23P21/00
Filed: 1992-07-29
Abstract: A valve assembling and checking method for mounting successively a spring 4 longer than the depth of a valve hole 2 formed in a valve body 1 and a spool 3 into the valve hole, comprises the steps of: pressing the spring 4 against the side wall of the valve hole 2, Figure 8B, to vertically hold the same by means of a pusher 52; engaging the spool on the spring; moving the spool 3 immediately above the valve hole, Figure 8C, to allow the spool to fall from the spool holding means 30, and repeatedly clamping and unclamping the spool to adjust the location of a spool which erroneously engages with an edge of the valve hole 2 so as to be correctly received in the valve hole 2. Further assembly procedures are concerned with checking the correct installation of the spring and spool by displacing the spool, Figure 10, downwards and measuring the resistive forces at different displacements, supporting a short spring in an elevated position, Figure 9(B), during location of the spool on the spring, and insertion of a spool with a freely-swingable cage, Figure 11. <IMAGE>

Title: Membrane separation process and apparatus for the separation
Inventor: BREWER GRAEME SPENCER
IPC: A23C9/142
Filed: 1993-07-20
Abstract: A membrane separation process and apparatus uses two different semi-permeable membranes to remove inorganic ions and low molecular weight species from high molecular weight species. The first semi-permeable membrane has a pore size to allow mainly diffusive transport of species across the membrane and a preferred pore size is 20-40 angstroms. The second semi- permeable membrane has a pore size to allow mainly convective transport of species across the membrane and a suitable pore size is between 60-120 angstroms. A stripping fluid contacts the other side of the semi- permeable membranes to carry away any species which pass across the membranes. The stripping fluid of the second semi-permeable membrane can be further treated by nanofiltration and/or ion exchange to remove ions from the stripping fluid. The method and apparatus is suitable for demineralisation of concentrated whey solutions. <IMAGE>

Title: Programmable signalling buttons
Inventor: CHEETHAM ROBERT
IPC: H04M1/247
Filed: 1994-02-14
Abstract: A range of supplementary or special services are currently provided by telecommunication network operators which may be obtained by sending a sequence of digits to the exchange as shown in Fig. 1(a). In order to simplify this task, the Customer's Premises Equipment (CPE) units, eg. telephones, connected to the network have programmable buttons. The operation of a button as shown in Fig. 1(b) causes the transmission of a defined code to an exchange forming part of the network to access a supplementary service. The programming may be carried out by transmitting programming signals from the exchange to a CPE unit using Frequency Shift Keying (FSK) signalling (Fig 2 not shown). Alternatively, the programming means may be a smartcard and a card reader connectable to the CPE unit, the smartcard being encoded with the programming information to programme the CPE unit (Fig. 3 not shown). <IMAGE>

Patent GB-2303213-A (GB)
Title: Simple fluid detector circuit
Inventor: ROE NICHOLAS
IPC: G01F23/24
Filed: 1995-07-11
Abstract: A mains frequency signal is applied to a fluid sensor V1,P1 via the secondary of a transformer TRANS1. When fluid is present, the signal passing through the fluid is detected by the circuit C2,D2,D3,C3,R1,Q1 so that transistor Q1 switches on and turns transistor Q2 off, opening the relay RY1. The sensor, detector, and relay drive circuit are all powered from a single secondary transformer winding. The detector is arranged such that more power is consumed when fluid is not detected. The transformer output voltage therefore increases when fluid is detected, creating hysteresis between switching points. The circuit may be used in an automatic drinks dispenser.

Title: Slice selection for NMR imaging
Inventor: CARLTON KEVIN JOHN
IPC: G01R33/54
Filed: 1995-08-21
Abstract: A method of selecting a region in a sample for NMR imaging comprises subjecting the sample to a steady uniform magnetic field and then performing the following steps I and II in either order:  I  (a) Injecting a hard 180{ RF pulse 2 into the sample while superimposing a steady magnetic field gradient 1 on the sample; (b) removing the gradient; (c) after a predetermined time, injecting a 90{ RF pulse 3 into the sample; (d) performing a desired NMR process on the sample; II Injecting at least a 90{ RF pulse into the sample, and performing the same NMR process as in step I(d); wherein steps I and II are performed sufficiently spaced apart in time to allow the nuclear magnetization of the sample to recover. The results from Experiments I and II are compared, typically subtracted, so that the effect due to the selected slice only is retained. Employing a hard pulse allows the use of a cheaper class C amplifier.
