Title: Passive radar target
Inventor: RIDGE LESLIE DEREK
IPC: H01Q15/23
Filed: 1986-06-23
Abstract: A passive radar target comprises a spherical lens 50, having a reflecting coating 51 applied to one portion of the surface thereof, the lens being constructed of a material having a dielectric constant selected such that radar waves striking the uncoated surface of the lens at an angle of incidence of 45 DEG  are focused on the remote coated surface of the lens. The extent of the reflecting coating used will depend upon the required angular response. In a small projectile, the coating preferably covers a hemisphere of the lens and is applied by spraying. The lens may be made from quartz. Alternatively, the lens is made of silica glass beads or silica flour with a polyster resin binder. By varying the relative weights of binder and silica glass beads the dielectric constant can be adjusted to the required value. <IMAGE>

Title: Dispensing arrangements for liquids and pastes
Inventor: WREN JOHN JOSIAH
IPC: B67D1/00
Filed: 1986-06-30
Abstract: An arrangement for dispensing liquids, eg carbonated beverages, or pastes comprises a container 10 made by a stretch-blow-moulding process from a plastics material which is flexible but substantially non-stretchable, preferably biaxially orientated polyethylene terephthalate, and a device which operates or is operable to apply a force to the container to eject the liquid or paste therefrom and/or to minimize head space in the container as liquid is dispensed. This force is applied to the container over substantially less than the area of the container projected in a plane at right angles to the direction of application of the force. The force may be applied by a caliper spring 13 operating to press together two rectangular frames 12 disposed on opposite sides of the frame, the container having dispensing valve 11 in its neck. Alternatively a large container with tube for dispensing to a remote tap is interposed between ribbed plates of a screw press having pressure sensors which activate a motor whenever applied pressure falls below a predetermined value (Figure 2). The container may be spherical and held between a hemispherical cradle and a hemispherical, electrically, hydraulically or pneumatically driven, piston (Figures 4A-4C). The dispensing valve 11 in the neck of the container preferably has a tubular section projecting into the container with a screw threaded member engaging within this section to form a spiral capillary exit passage for controlling the release of gas during dispensing. A dip tube, which gathers as a coil at the bottom of the container as the container collapses, may be attached to the dispensing outlet (Figure 5). <IMAGE>
Patent GB-2196011-A (GB)
Title: Improvements in the production of graft copolymers
Inventor: KROMOLICKI ZYGMUNT
IPC: C08F236/06
Filed: 1986-10-17
Abstract: A graft copolymer consisting of a rubbery core and a hard shell is produced by preparing the rubbery core by polymerizing butadiene and styrene, using the emulsion polymerization method. By employing higher temperatures than normal, 90 DEG  C or higher, the reaction times are 3-7 hours, and the latex particle size is above 1500 A. Then the graft copolymer shell is made under standard conditions and the graft copolymer is isolated and dried. Thus prepared graft copolymer functions as an impact modifier of hard and brittle polymers such as PVC, Polystyrene and Polymethyl methacrylate. When the two are blended and compounded toughened versions of these polymers are produced.

Title: Signal distribution network system
Inventor: BAXTER THOMAS
IPC: H04N7/16
Filed: 1988-01-22
Abstract: A signal distribution cable network system in which frequency division multiplexing is employed to provide a plurality of information channels. A channel allocation controller (CT) allocates free channels on request for the transport of signals from a local signal source (SS1, SS2, SS3) to a signal destination receiver (SR1, SR2, SR3) connected to the network. The local signal source includes a programmable modulator (CFS, VCO, MOD) which is set by the channel controller (CT) to operate at the carrier frequency of the selected channel. The signal level of the signals transmitted by the local signal source is measured in the controller and adjusted to compensate for signal attenuation by a command signal sent by the controlle to the programmable modulator in the local signal source.

Title: Bipolar/cmos integrated circuit
Inventor: SACHITANO JACK
IPC: H01L21/336
Filed: 1988-08-18
Abstract: A mixed bipolar-CMOS integrated circuit comprises a high performance NPN bipolar transistor 114 formed simultaneously with a PMOSFET 118 and an NMOSFET 120. Gate 146, 148 and base 140 contacts are formed in a first polysilicon layer. The base contacts are implanted with P+ ion concentrations for diffusing base contact regions of the substrate in a later drive-in step. Source 168A, 170A, and drain 168B, 170B contacts and emitter contacts 166 are formed in a second polysilicon layer. The source and drain contacts are formed as a unit and then separated into discrete contacts by a spin-on polymer planarization and etch-back procedure. The gate and base contact structures serve as a mask to self-align the implants. Then, the gate and base structures are enclosed in an oxide box having sidewalls. A shallow P+ intrinsic base is formed, which is spaced from the P+ base contact diffusions by a lightly-doped margin. Then, the emitter contact polysilicon is implanted N+ and a drive-in step forms a shallow emitter within the P+ base. The FET devices likewise have graduated doping profiles in their source and drain diffusions. <IMAGE>
