Filed: 1994-08-23
Granted: 1997-04-24
Abstract: The compound of formula I <CHEM> and its enantiomer with the (S) configuration can be prepared by appropriate substitution, protection and/or deprotection from the compound of formula II <CHEM> which itself can be prepared by enantiospecific monohydrolysis of 2,2-bis(hydroxymethyl)tetrahydrofuran dibutyrate. They have unusual pharmacological activity: the compound of formula I has activity in treating multiple sclerosis and its enantiomer in treating tumors. The compound of formula II and its protected forms are useful intermediates for preparing further optically pure pharmacologically active compounds having an asymmetrically substituted carbon atom adjacent to the oxygen atom in a tetrahydrofuran ring.

Title: Phase locked loop system including analog and digital components
Inventor: BALABAN ALVIN REUBEN
IPC: H04N9/45
Filed: 1987-05-26
Granted: 1990-06-07
Abstract: A phase locked loop is provided, which may be used in digital systems having clock signal frequency instabilities. The PLL has an analog oscillator (342) the frequency of which is determined by an analog control signal. The oscillatory signal is digitised (344) and phase-compared (338) with a digital reference signal, the digital output of the phase comparator being converted (340) to an analog signal to provide the oscillator control signal. In an application of the invention to a digital television receiver having a line-locked clock, the phase locked loop (350) regenerates two quadrature phase related subcarrier signals (COS,SIN) that are used to synchronously demodulate the chrominance signal components (CB) of the composite video signals into two color information signals (I,Q). The analog voltage-controlled oscillator (342) of the phase locked loop (350) generates a signal that is independent of any frequency instability in the line-locked clock signal. The analog-to-digital converter (344) digitizes this signal to provide one of the subcarrier signals, from which is generated the quadrature subcarrier signal, for example from a read-only memory (348). The two color information signals (I,Q) are obtained by multiplying (332,334) the chrominance signals by the first and second subcarrier signals. The phase comparator (336) determines the phase of the vector sum of the two color information signals and compares this against a desired phase value to generate a phase difference signal. The phase difference signal is filtered (338) and applied to the digital-to-analog converter (340) whichprovides the frequency control signal for the analog oscillator (342). A tracking filter (346) may be inserted at the output port of the analog-to-digital converter (344) to allow its quantization resolution to be reduced without affecting the performance of the phase locked loop.

Title: Hot-sprue valve
Inventor: MORRISON ROCKY V
IPC: B29C45/26
Filed: 1981-10-19
Granted: 1985-07-18
Abstract: A hot sprue assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The hot sprue assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The hot sprue assembly includes a hot sprue bushing cooperating with a generally conically-shaped dispersion head to define an open an relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold .avity for cooperating with the dispersion head to mold a central aperture into the disc. Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during solidification of the material within the mold cavity, permits the material within the mold cavity to solidify up to the gate without substantial solidification of material within the sprue assembly. The gate is disposed at a plane recessed slightly from the general plane of the solidified disc to prevent any surface discontinuities arising by retraction of the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.

Title: Automatic loading of flat parts in a holder - with accurate spacing suitable for a row of inserts in pressure die castings
IPC: B22D17/24
Filed: 1971-08-31
Abstract: A loading device where flat parts are vibrated along a feed bar into a magnetic field in which they repel each other due to the effect of like poles and become separate. They are then drawn off the bar by >=1 suction pipe which retracts leaving the parts against a holding magnet from where they are pushed down a channel under which a slot is located in the holder. The process is partic. suited to the accurate location of thin parts or blades in a row, as the holder is located in a table which can be removed accurately stepwise in line with the channel. As an example, a die insert for a pressure die-casting die can be automatically loaded with parts which will form part of the casting and the time cycle of the loading device can be adjusted to match the pressure die casting machine.

Title: Compensation circuit for inductive flow-meter - feeds voltage proportional to induction of exciting alternating field to decoupled amplitude and phase controllers
IPC: G01F1/60
Filed: 1972-07-06
Abstract: A compensation circuit for an inductive flow-meter has a transducer through which the fluid medium passes. The circuit eliminates the quarterature voltage of the signal proportional to the flow rate. This is achieved without an extra input circuit conductor which would detract from measurement results because of its capacitance. The transducer has an exciter coil and measurement electrodes on which appear the useful and quadrature signals. A voltage proportional to the induction of the exciting alternating field and inductively decoupled from the exciter coil is fed to decoupled amplitude and phase controllers. The electrode voltage is input to a buffer amplifier whose output is compared with the phase and amplitude controlled compensation signal.

Abstract: Such dummy shells are to fulfil the following safety condition in a reliable manner: none of the steel powder particles shall perforate a sheet of 200 g/m<2> quality paper held in a frame 40 m away from the muzzle of the gun barrel. However, accidents, in particular involving eye injuries, have occurred during manoeuvres as a result of non-compliance with the prescribed safety distance. 
<??>Using the filler particles according to the invention and/or pellets compressed from said particles, the hazard range in front of the barrel muzzle is considerably reduced to a distance of about 10 m. This is achieved in that the steel powder, which is sieved off after an impact and abrasion treatment lasting longer than 60 minutes, has a dust-free grain fraction of less than 0.315 mm and a filling density of between about 3.9 and 4.6 g/cm<-><3> and can be compressed in such a way that the resulting density of a pellet to be received in the dummy shell is between about 6.5 and 7.15 g/cm<-><3> depending on the height and shape of the pellet.
