Patent GB-2241411-A (GB)
Title: Improved synchronization technique
Inventor: WHITTINGTON CHARLES L
IPC: H04J3/06
Filed: 1991-02-27
Abstract: An improved synchronization technique is provided that may be used to synchronize outlying "downstream" nodes in a cellular radio telephone system to a master node. According to the invention, the master node starts a timer while simultaneously sending a predetermined signal known as a "token" to a target node. Upon receipt of the token, the target starts a timer and stores the token. The target then waits for the next available time when it can return the token to the master. When it later returns the token to the master, the target stops its timer, thereby generating a "holding time" for the token. Upon receipt of the token, the master stops its timer, thereby generating an "elapsed time" for the token. The time delay for the channel interconnecting a target and the master may then be computed as one-half the difference between the elapsed time and the holding time. Moreover, based on this time delay information, the target may then be synchronized to the master. <IMAGE>

Title: Hydraulic power transmission joint
Inventor: SUZUKI SATORU
IPC: B60K17/35
Filed: 1991-05-01
Abstract: Two rotary shafts to transfer a motive power, for instance for a four-wheel drive vehicle, are relatively rotatably coupled, one of the shafts 22 being coupled to a rotor 20 and the other 14 being coupled to a cam 10. A plurality of axial plungers 26 which execute a stroke motion owing to the relative rotation with respect to the cam is provided in the rotor. The oil injection and discharge into/from the plunger chambers 24 is controlled by a rotary valve 30. The rotary valve automatically switches a phase relation by carrying out a limited rotation with respect to a housing 18 integral with the cam so as to obtain correct opening/closing timings even when the direction of the relative rotation changes. The rotary valve 30 otherwise rotates integrally with the cam and opens or closes intake/discharge holes 25 of the plunger chambers 24 for a plurality of intake ports 32 and discharge ports 36 which are alternately formed in the rotary valve. The discharge ports 36 on the front surface of the rotary valve are mutually coupled by communicating grooves 38 formed on the back surface. An orifice 42 is formed between the communicating grooves 38 and the intake port 32 so as to provide the necessary flow resistance. <IMAGE>

Title: RLG scale factor correction and lock-in measurement employing readout waveform distortion
Inventor: BOWSER MARK P
IPC: G01C19/66
Filed: 1991-06-13
Abstract: The apparatus includes circuitry (30) coupled to at least one output signal of the ring laser for measuring a duration of a predetermined portion i.e. the positive signal part of a cycle of the output signal and for measuring a period of a cycle of the output signal. The duration of the predetermined portion, or positive excursion, is shown to be a function of the lock-in rate of the ring laser. The apparatus further includes circuitry for determining a ring laser scale factor nonlinearity compensation factor as a function of (a) the measured duration of the predetermined portion of a cycle of the output signal, (b) the measured duration of the period of the cycle of the output signal, and (c) a value of a ring laser bias.

Title: Optical switch
Inventor: O'DONNELL ADRIAN CHARLES
IPC: G02F1/313
Filed: 1991-09-13
Abstract: An optical switch comprises light waveguides terminating at one or more first nodes 1 and two further nodes 3, the switch being operative to direct a signal between a first node and one of the further nodes upon the application of a control signal to the switch. The waveguide 5 terminating at one of the further nodes is more transmissive than the waveguide 6 terminating at the other of the further nodes so that substantially the entire proportion of a light signal is directed to that further node in the absence of the control signal. As shown the difference in transmissivity is achieved by making one output waveguide 5 of greater width. Alternatively different amounts of dopant are diffused into the respective waveguides. <IMAGE>

Title: Refractory stopper rod with a lined channel
Inventor: LEE STEPHEN JOHN
IPC: B22D41/18
Filed: 1992-01-09
Abstract: A stopper rod (3) has a refractory body in which at least one channel (20; 40) is formed which is bounded by a refractory membrane (6; 10) which is substantially gas-impermeable and that membrane has a contiguous barrier (7; 11) between it and the surrounding refractory material to act as a buffer zone to counteract the effects of differential expansion and contraction arising from mechanical or thermal stresses. The refractory membrane may be formed of dense alumina or silicon nitride-bonded silicon carbide materials. The barrier layer may be formed of a fibrous ceramic material co-pressed into the refractory body to form an inseparable boundary layer between dissimilar refractory materials of the lining and the bulk of the stopper. Alternatively it may be formed of co-pressed mullite or corundum. <IMAGE>

Title: Non sharp cut filters for Weston Clean PAL
Inventor: DREWERY JOHN OLIVER
IPC: H04N9/64
Filed: 1992-01-24
Abstract: In a Weston Clean PAL system an assembler has filter functions F1, F2 (figs 7a, 7b) for the luminance and chrominance components respectively and the splitter has corresponding filters having functions F3, F4 (figs 7c, 7d). The transfer functions are such that F4 and F3 are shifted mirror functions of F1 and F2 respectively, and the products F1 F3, F2F4 are Nyquist filters Ny, Nc. The preferred filter transfer functions take the form:      F1 = (L2 + L1)/2 + (L2 - L1) z<-1>/2      F2 = (H1 - H2)/2 + (H1 + H2) z<-1>/2      F3 = (L2 - L1)/2 + (L2 + L1) z<-1>/2      F4 = (H1 + H2)/2 - (H1 - H2) z<-1>/2      and wherein      H1 (f) = L2 (2fsc - f) and      H2 (f) = L1 (2fsc - f) Thus the filters are non-sharp cut and are compatible with normal PAL. <IMAGE>

Title: Vehicle movement dynamics control system
Inventor: HADELER RALF
IPC: B60T8/172
Filed: 1994-01-20
Abstract: A vehicle movement dynamics control system has a higher-level vehicle movement dynamics computer downstream of which a brake controller is connected. The latter has a channel for controlling the yaw velocity to a desired value and a channel for limiting the attitude angle. The computer prescribes the desired value and the limit value, and determines which channel is effective on the basis of the driving situation. The two channels generate a control signal which is conducted via a control amplifier having a proportional and a differential component. An actuating signal which is used to input brake pressure at the wheel brakes is formed from the signal components produced, the instantaneous driving situation in the two cases being classified into one of a plurality of classes, and this classification also serving to determine the wheels at which brake pressure is input. A rear axle steering controller is also responsive to yaw velocity and attitude angle.
