Title: Reflective road stud
Inventor: LLOYD JOHN
IPC: E01F9/07
Filed: 1989-02-21
Abstract: A reflective road stud comprises an open topped rectangular shell formed in a resilient material to locate in a road mounted socket, a transverse wall having banks (16) of reflective elements on either side thereof, the wall being mounted on resilient arms extending from both ends of the wall to opposing sides of the shell to support the wall extending across and projecting above the periphery of the shell whilst permitting the wall to be depressed into the shell and restoring the wall to the projecting position when released, the arms also resisting resiliently movement of the wall transverse to its lengthwise direction. Spaced wiper elements (21) are mounted in the shell to engage the reflective elements on either side of the wall when the wall is depressed into the shell, the wiper elements have resilient mountings (20) which bias the wiper elements against the defective elements whilst permitting the wiper elements to accommodate said transverse movement of the wall. <IMAGE>

Patent GB-890688-A (GB)
Abstract: 890,688. Electrical measuring systems. SCHENCK MASCHINENFABRIK G.m.b.H., CARL. Aug. 5, 1958 [Aug. 10, 1957], No. 25000/58. Class 40 (1). The invention relates to electrical apparatus for measuring the unbalance of a rotor in each of two bearing planes. In a first embodiment (Fig. 1) the unbalance of a rotor 5 at a first bearing is measured by a transducer 12, the rotor shaft 4 also driving a reference generator 6 supplying voltages in quadrature having the same frequency as the unbalance voltage output from transducer 12. One of the quadrature voltages is fed to two windings 17, 18 of a motor 80, the other pair of windings 19, 20 being fed with the unbalance voltage modified by a portion of the other quadrature voltage, tapped off by the slider 24 of a potentiometer 23. If any out-of-phase component of voltage is fed to windings 19, 20, the motor 80 runs to move the slider 24 until this component is eliminated. Thus, the rest position of slider 24 indicates the value of the X component of the unbalance and a similar arrangement having a motor 81 determines the Y component of this unbalance. The equipment is switched or duplicated to determine the components of unbalance at the other rotor bearing plane. In a second embodiment (Fig. 2) the first motor rotates the stator of the reference generator 50 until the out-of-phase unbalance component is eliminated, the rest position of slider 45 of the other potentiometer then indicating the magnitude of the unbalance and the angular position of the stator of generator 50 indicating the phase angle of the unbalance. The second motor 83 may be replaced by a wattmeter indicating the magnitude of the unbalance, when only one voltage output from generator 50 is required, not two voltages in quadrature.

Title: Edible fatty composition containing bleached fish oils
Inventor: POLMAN ROBERT GEORGE
IPC: C11B3/08
Filed: 1990-02-15
Abstract: The invention relates to fatty compositions, containing fish oils and to methods of preparing those compositions. It is known for methods of refining fish oil to include a bleaching step. In this step, bleaching earth is added to the oil and later separated. One problem with this process is that the earth may spontaneously catch fire due to the oxidation sensitive components contained therein. The invention solves the problem by mixing an excess of vegetable oil with the fish oil prior to the bleaching step.

Title: Power supply
Inventor: HUGHES NORMAN LESLIE
IPC: H01H47/00
Filed: 1990-05-01
Abstract: A power supply unit utilises first and second input relays (3, 4) each connected to a respective mains socket input line (L1, L2) such that, only when both of the inputs are connected to the supply, thereby energising the two relays, do both relay contacts (R3, R4) close to provide a series connection of a further two relays (1, 2) across the two input supplies, which, when energised, close respective relay contacts (R1, R2) to connect the output (L3) across both of said inputs to enable the output to draw power from both input sockets. Thus, the output socket is able to draw up to 25 amps from two conventional 13 amp sockets. If either of the two inputs is disconnected, the supply is cut off in a fail-safe condition. <IMAGE>

Title: Cable converter unit (cable box) control by vcr
Inventor: KIM SUNG JO
IPC: H04N7/16
Filed: 1992-12-10
Abstract: A VCR includes circuitry for detecting the presence of a television signal and control code transmission circuitry for remotely controlling a cable box. Because the VCR is coupled to the output of the cable box, the VCR can monitor the television signals received from it to ensure that commands from the VCR are executed. A skip list programmed into a VCR may be used to control the cable box. That is, in response to a channel up command received by the VCR, the VCR would not change channels itself, but rather controls the cable box to select the next preferred channel entered in the skip list of the VCR. In this mode of operation, the channel tuning keys (e.g., CHAN UP, CHAN DN) of the VCR remote control are used to control an external source of signals, while the VCR mechanism control keys (e.g., PLAY, STOP, RECORD, FAST FORWARD) control the operation of the VCR. Those portions of the VCR concerned with channel tuning may receive power from the standby power supply (SB) normally provided for powering the iR receiver. <IMAGE>
