Title: Plastics film severing tool assembly
Inventor: SHEARER IAN JAMES
IPC: B26F1/38
Filed: 1985-07-25
Abstract: The tool assembly is used in making photographically reducable artworks for precision masks used in the etch control of circuit boards, for example those used for microwave integrated circuits, where the artworks comprise two films of polyester material stuck together, one of a clear material and one of a coloured material. The tool is used to sever the coloured material in a chosen pattern and comprises a heated slender tool bit (B) capable of being inserted into the coloured material and locally melting it as the tool assembly is traversed around the pattern. The tool has a symmetrical tip (B1) so that it does not have to be reoriented for cutting in different directions, and can replace the stylus in a conventional flat bed x.y plotting machine. The tool is heated by a resistance coil (D), and is carried by a metal housing (A) in electrical and heat insulating collars (C2, C1), being an interference fit in collar (C2) which is axially adjustable, and a sliding fit in collar (C1) which is fixed in the housing (A). <IMAGE>

Patent GB-2185785-A (GB)
Title: Gear pump type liquid flow meter
Inventor: HUMBERSTONE VICTOR
IPC: G01F3/10
Filed: 1986-01-25
Abstract: The rotation of the pump gears 12, 14 is monitored to give a reading of liquid flow. The pump is maintained with a zero pressure drop across it, and in order to maintain this zero pressure drop in spite of possibly increasing or decreasing liquid demands by the liquid consumer, a sensing piston 32 is arranged in parallel with the pump. The sensing piston will move when a pressure difference occurs across the pump, and a signal is then produced representative of the sensing piston position which alters the speed of revolution of the gears in the pump, and which is also summed with the signal denoting the rotation or speed of the gears in order to produce a corrected total figure for liquid flow. <IMAGE>

Patent GB-2198231-A (GB)
Title: Rotational motion sensor
Inventor: SATCHELL DAVID WILLIAM
IPC: G01C19/56
Filed: 1986-11-28
Abstract: A rotation sensor device 11 includes a laminar body 12 supported on a taut filament 13 and undergoing torsional oscillation about an axis Z coincident with the filament 13. Rotation of the device, about an axis X through the plane of the body 12, induces an oscillatory torque, about an axis Y mutually perpendicular to the other two axes, the magnitude of which corresponds to the rate of rotation. Positive feedback maintains body 12 in oscillation at the resonant frequency (with electrostatic coupling) and there is capacitative detection of the oscillations. Three rotation sensor devices are employed in an initial guidance system for a projectile. Device 11 is formed by selective etching from a body of single crystal silicon. <IMAGE>

Title: Racemic and optically active fatty amino acids, their homo- abd hetero-oligomers and conjugates, the process of their production, their pharmaceutical composi
Inventor: GIBBONS WILLIAM ANTHONY
IPC: C07D489/02
Filed: 1988-04-19
Abstract: It has been found that by using dimethyl formamide as a part of the solvent, the Albertson method for preparing amino acids can be applied to the preparation, in good yield, of long-chain aliphatic amino acids, previously obtainable only in poor yields. The products, some of which are novel, have useful properties per se, due to their lipid-like structure; and, by means of coupling reactions using a carbodiimide and a phase-transfer catalyst, can be homo- or hetero-oligomerized to useful lipopeptides. These monomers or lipopeptides can be incorporated into bioactive peptides to increase their hydrophobicity, or conjugated with pharmaceutical agents to modify their pharmacokinetic properties, including translocation across biological membranes and metabolic stability. They can also be polymerized, via their Leuchs anhydrides or active esters, to lipoproteins.

Title: Signal analyser
Inventor: PITCHARD JONATHON ALEXANDER SK
IPC: G06F17/14
Filed: 1989-10-18
Abstract: A signal analyser (10) incorporates a signal sampling limiter/latch (16) connected to a logic array (18) arranged to multiply latch output signals V(t) by -sin( omega t+ theta ) and -cos( omega t+ theta ), where  omega  is the analyser angular frequency, t is time and  theta  is a stored phase angle. The sine and cosine products in one-bit form are multiplied by 1/r at EXOR gates (32, 34) where r is a signal magnitude stored logarithmically in a latch (60), and the result are employed to augment values of  theta  and logr stored in latches (50, 60). Values of logr output from the latch (60) are decremented before augmentation to implement exponential decay and a finite analyser Q factor, and are in undecremented form converted to 1/r in a look-up table EPROM (40) for provision to the EXOR gates (32, 34). The quantity ( omega t+ theta ) is generated by adding the stored value of  theta  to the output of counting means (80) counting in increments of  omega  at a system clock rate. The system dock is also employed to activate sampling and output from the  theta and logr latches (50, 60). The analyser (10) provides the phase and the logarithm of the amplitude of the component of angular frequency omega  in the input signal V(t). This deconvolutes phase and amplitude. <IMAGE>
