Title: Combined electrical generator, electromagnetic propulsion engine and internal combustion engine
Inventor: ROCHE PAUL
IPC: F02B63/04
Filed: 2013-08-06
Abstract: Hybrid electric vehicles require two motors or engines; one for internal combustion and a second for electronic propulsion. Here, as shown in figure 3, a novel hybrid engine is proposed. The proposed design is capable of permitting internal combustion and electric propulsion within the same engine block. Friction and/or heat dissipation from the engine is reduced. The proposed scheme utilises a set of permanent magnets C attached to connecting rods CR1 and to the same eccentric crankshaft ECS as the internal combustion engine, and is provided with motive force by electrically powered switching bipolar electromagnets A1, hence minimizing losses due to friction. It is more efficient than current hybrid engines or alternator motors due to reduced friction. The use of thermal and magnetic insulation AER in combination with appropriate cylinder timing circuitry represent advantages over existing technology and it may be used in alternator motor form to generate electricity for vehicular and other purposes.

Title: Mass spectrometer with interleaved acquisition
Inventor: KENNY DANIEL JAMES
IPC: H01J49/00
Filed: 2015-04-24
Abstract: A method of mass spectrometry comprises passing ions through a first stage and a second stage of a mass spectrometer and monitoring a first ion acquisition 5 for a first dwell time. The mass spectrometer is reconfigured to monitor a second ion acquisition 6 for a second dwell time starting at a time after the end of the first dwell time.

Title: Method for controlling the lateral position of a tape head of a magnetic tape drive
Inventor: SIMEON FURRER
IPC: G11B5/584
Filed: 2016-10-27
Abstract: Lateral position of a tape head 108 of a magnetic tape drive is controlled. A first servo signal is determined by reading position marks from a first servo band 114 on a magnetic tape using a first sensor 110 and a second servo signal is determined by reading position marks from a second servo band 114 on the magnetic tape using a second sensor 112. One of the servo signals is delayed relative to the other and an average signal is calculated based on the first servo signal and the delayed second servo signal. Lateral position of the tape head is determined from the average signal and the tape head position is controlled to decrease deviation of lateral position. The delay is based on the frequency of longitudinal oscillation of the magnetic tape 102. Disturbance contained in the delayed second servo signal caused by longitudinal oscillation of the tape will cancel out the disturbance in the first servo signal. The delay can be caused by tilting the tape head and can equal an odd numbered multiple of half the inverse frequency f, e.g. Δt = n/2f ± δ where n= 1, 3, 5, and 0 ≤ δ ≤ 1/6f.
