Patent GB-2161344-A (GB)
Title: Transmission of digital data
Inventor: MOULSLEY TIMOTHY JAMES
IPC: H04L1/04
Filed: 1984-07-06
Abstract: The transmission of digital data over a data link, particularly an H.F. radio link, can be corrupted by narrow-band, high level interference signals randomly distributed in frequency. The uncorrupted transmission of data can be made more possible by a frequency diversity digital data transmission system in which a signal channel is divided into a plurality of lesser bandwidth sub-channels, each of which is modulated across substantially its entire bandwidth by a multi-level, spectrally efficient modulation scheme, for example 8PSK, 16QAM, 64QAM. In a receiver the sub-channels are examined for narrow-band interference and the data signal is demodulated using a decision algorithm based on the sub-channel outputs, and an assessment of sub-channel reliability. <IMAGE>

Title: Resonant current driven power source
Inventor: GALLIOS GEORGE C
IPC: H02M3/337
Filed: 1985-07-24
Abstract: A resonant current-driven power source is disclosed. Preferably, the power source is a DC to DC converter regulator including an inductor (L1) and capacitor (Ceq) electrically coupled to one another and an input inverter (100) which converts an input DC voltage (Es) into an AC voltage having substantially no DC component and applies the AC voltage across the LC circuit in a manner which causes the inductor and capacitor of the latter to resonat with one another whereby an AC voltage appears across the capacitor. An output circuit (16) converts the AC voltage appearing across the capacitor into a DC output voltage. A control circuit (18) controls the operation of the inverter circuit to regulate the output voltage. The inverter circuit also includes a step-up transformer (98, 99) for increasing the magnitude of the AC voltage across the LC circuit to a value greater than the input DC voltage (Es). <IMAGE>

Title: Method of forming polymeric microcapsules containing oily liquid
Inventor: OHGA KUNIHIKO
IPC: B01J13/16
Filed: 1987-05-22
Abstract: Microcapsules containing an oily liquid are formed by polymerising melamine and formaldehyde or an initial precondensate thereof at the surface of droplets of a hydrophobic oily liquid (e.g. containing a color-forming agent in a biphenyl) containing (a) a monoamine (aliphatic) or a polyamine (e.g. an aliphatic or aromatic diamine or a polymeric amine) and (b) a polyisocyanate or prepolymer thereof; e.g. the oily mixture is emulsified in an aqueous solution of a water-soluble high polymer, e.g. gelatin; melamine and aqueous formaldehyde or an initial condensate thereof is added, and the pH is made acidic and the temperature raised to cause formation of microcapsules of melamine-formaldehyde containing the oily liquid.

Title: Heating water for drink-making apparatus
Inventor: KOMAR MICHAEL NICHOLAS
IPC: A47J31/057
Filed: 1987-06-11
Abstract: A filter coffee machine includes a water tank (7) from which water is pumped over ground coffee in a filter holder (5). The pumped water from the tank (7) flows along a tube (14) leading from a heatable chamber (11) to the junction of two arms (16,18). A partition (20) at the junction divides the flow into two parts each of which flows along one of the two arms (16,18). One arm discharges water over the coffee while the other discharges water back into the tank (7). In this way, the temperature of the water used for infusion gradually increases and this reduces the extraction from the ground coffee with a resultant improvement in the taste of the coffee. <IMAGE>

Title: Hands-off, two-way vehicle radio
Inventor: BEST PETER JAMES
IPC: H04B1/38
Filed: 1987-09-08
Abstract: Vehicle two-way radio communications apparatus comprises a transceiver unit 1, a loudspeaker unit 7, a microphone unit 9 and a control unit 4 incorporating a transmission switch (13, Fig 2) and a volume control (12) mounted in a vehicle. The control unit 4 is mounted separately from, but is electrically connected to the transceiver, loudspeaker and microphone units, while the microphone unit 9 is mounted remotely from the control and transceiver units, at a location which positions the microphone adjacent the head of a user sitting in the vehicle. This enables the controls to be positioned conveniently for the user, and the apparatus to be used without holding the microphone, which can interfere with control of the vehicle. The loudspeaker unit 7 may also be remote from the transceiver and control units, preferably being mounted from an upper seat belt anchorage 8, with the microphone unit 9 mounted from it. <IMAGE>

Title: Process for the intermediate storage of plastic material to be processed
Inventor: SAUERBRUCH ERNST
IPC: B65D81/20
Filed: 1987-09-30
Abstract: Plastic material to be processed on an injection molding machine is poured into convenient material containers (2) outside the machine area. After the closing of the material container with covers (5) the air inside the material container is evacuated through a check valve (9) placed in the cover and a vacuum is created. Thus the plastic material in the material container is no longer exposed to the harmful effects of oxygen and can thus be stored for a considerable time in the material container. <IMAGE>
Patent GB-2197762-A (GB)
Title: Motor control circuit
Inventor: WILKINSON RAYMOND
IPC: H02P7/08
Filed: 1987-10-19
Abstract: An analogue to digital convertor applied to eg fan motor speed control provides for a continuously variable setting control 12, the output of which is applied to a plurality of comparators, each associated with a fixed resistance value RA, RB... and by which one or more fixed resistances are switched in or out of circuit with the electrical load. The threshold valve of comparator 13 (controlling resistor RA) is set by resistors R3 and R4, but influenced by the switching of comparators 14, 15 via R5 and R6. Thus, as the control 12 is adjusted, comparator 13 switches on RA, then comparator 14 switches on RB, but by changing the threshold of comparators 13 RA is switched off. As the control 12 is adjusted further both RA and RB may be switched on in parallel before RC is switched on, and RA and RB switched off. <IMAGE>
