Title: Frequency synthesiser
Inventor: BEALE CHRISTOPHER JACQUES
IPC: H03J5/02
Filed: 1986-06-06
Abstract: A locked-loop frequency synthesiser for use in a TV tuning system, comprising a local oscillator 2 for producing an output signal which is fed to a programmable element and signal comparator 42, which may be a divider or a counter.

Title: Automatic engaging arm device especially for agricultural trailer implements
Inventor: MEURS WILHELM
IPC: A01B17/00
Filed: 1987-11-13
Abstract: For a plough with cutting width adjustment a secure catching of the trailer implement independently of the cutting width set in each case is always ensured by the packer engaging arm which is made automatically adjustable. The engaging arm, or the engaging member arranged on its end, is articulated automatically adjustably and pivotably on the plough frame and consists of a linkage the outward pivoting range of which is influenced through the control rod. Thus the catching point is kept in an optimum position in each case. The same also takes place with the pulling point of the engaging arm, which is likewise automatically shiftable by a stop on the cross-bar of the engaging member.
Patent GB-2212914-A (GB)
Title: Selective staining method for human papillomavirus in cervical smears
Inventor: FARAKER CHRISTOPHER ADDISON
IPC: C12Q1/04
Filed: 1987-11-23
Abstract: The method, which demonstrates human papillomavirus infected epithelial cells in cervical smears, relies on the resistance of the virus to denaturation by the enzyme deoxyribonuclease (DNAse). A layer of bacteriological nutrient agar is placed over the cervical smear slide and innoculated with DNAse producing bacteria. After incubation at 37 DEG C for 18 hours, the slide is stained by a specific deoxyribonucleic acid (DNA) stain such as the Feulgen technique. Epithelial cell DNA is denatured by the DNAse produced by the bacteria and fails to stain. As the human papillomavirus is resistant to denaturation by DNAse, the DNA of the virus is positively stained.

Title: Fabric to fabric bonding
Inventor: BUCKLE JAMES LESLIE
IPC: A41D27/02
Filed: 1988-09-13
Abstract: An applique (12) and a layer of fabric material such as in a garment, where the fabrics in each case are made by weaving or knitting, are joined together by placing a layer (10) of thermoplastics film between the two fabric layers and applying pressure and a high-frequency electric current across the layers at preselected zones. This causes the thermoplastics layer (10) to plastisize and the pressure forces the thermoplastics material into the two fabric layers to effect bonding. Only one layer of thermoplastics material is used to produce an effective and strong bond.

Title: Railway network monitoring and control
Inventor: WHYTIE ADRIAN
IPC: B61L25/02
Filed: 1990-05-29
Abstract: A railway network monitoring system monitors the position and speed of a train (1) on a track (2). An aerial (3) and receiver (4) receive signals from earth satellites of a global positioning system, for example the Navstar System. The signals are passed to a processor (5) which determines the location of the train (1). The speed of the train (1) is measured by a speed sensor (6) and the measured value is input to the processor (5). The processor (5) accesses a digitally coded information from a data store (7) of a map of the train's route and associated speed data. The processor (5) then compares the train's determined location with the map and compares the known speed of the train (1) with the maximum permissible speed programmed into the data store for that particular location. The train's location, speed and difference from the maximum allowed are displayed on a visual display unit (8). If the train (1) is exceeding the allowed maximum on alarm (9) is activated to warn the driver. If the train (1) is exceeding the speed limit by a predetermined margin the power is reduced and/or the brakes applied by a power control unit (10) and brake control unit (11) respectively.
