Title: Rifle sight
Inventor: HALE ROGER
IPC: G01S17/86
Filed: 1987-01-05
Abstract: A rifle sight comprises a casing 10, a telescope 13 having an objective lens 16, an eyepiece 16, a fixed graticule 20 and an adjustable graticule 21.

The reflected pulse is received by objective lens 16 and reflected by a beam splitter 30 to detector 27 which calculates the range of the target and the range is displayed on display 28. The sniper then uses the range information to adjust the horizontal cross wire of graticule 21 and graticule 21 is aligned on the target when firing the rifle. <IMAGE>
Patent GB-2201096-A (GB)
Title: Emergency escape breathing apparatus
Inventor: BREWER STEPHEN JON
IPC: A62B17/04
Filed: 1987-02-13
Abstract: In emergency escape breathing apparatus oxygen is fed from a cylinder 7 in a breathing bag 6 to a flexible hood 1 through an inhalation channel which includes an inhalation valve 12 and a pressure responsive valve 9. The pressure responsive valve 12 is maintained in the open condition by a pressure, which may be either a negative or a positive pressure, generated by the flow of oxygen from the cylinder 7 into the breathing bag 6. When oxygen flow from the cylinder 7 ceases, the pressure responsive valve 9 closes to a condition in which only a restricted gas flow through the inhalation valve 12 is permitted, and the resultant increased inhale resistance warns the wearer of the hood 1 that the oxygen supply is exhausted and that the hood 1 should be removed. <IMAGE>

Title: Chair or bed raiser
Inventor: NIXON ARTHUR
IPC: A47C3/38
Filed: 1988-08-10
Abstract: A chair or bed raiser, for raising the height of an easy chair or divan bed to facilitate use by the elderly or handicapped, comprises a frame having a central portion (10, 12) to which are pivotally mounted the radially inner ends of four telescopic arms (14). The radially outer ends of the telescopic arms (14) carry floor-engaging feet (24), and also carry upwardly projecting spigots (22) which locate in the castor sockets of the chair or bed. The pivotal mounting of the arms (14), and their ability to telescope, enable the spacing of the spigots (22) to be adjusted to suit an individual bed or chair to be raised.

Patent GB-2211685-A (GB)
Title: Differential volume adjusters
Inventor: THOMAS IAN GRENVILLE
IPC: G10L21/02
Filed: 1988-10-12
Abstract: A public address system includes a microphone (2), a variable gain amplifier (4), at least one loudspeaker (6). The differential volume adjuster includes a second microphone (8) placed in the vicinity of at least one loudspeaker (6), a substractor (10) and an amplitude equalizer (12). The gain of the amplifier (4) is controlled by means of a signal (Z) output from the substractor (10) representing only the level of the ambient noise. The substractor (10) subtracts the magnitude of a signal (Y) output from the equalizer (12) from a signal (X) output from microphone (8) being the combined audio output (A1) from the loudspeaker (6) and the ambient audio noise (A2). The equalizer (12) receives a first input signal (W) from the microphone (2) and a second input signal (V) from the output of the amplifier (4). Thus the gain of the amplifier (4) is varied so as to compensate for varying changes in the level of the background noise to improve the intelligibility of the audio output signal from the loudspeaker (6). The system could be used in a fire alarm unit where microphone (2) is replaced by an electric signal generator energised on detecting a fire and loudspeaker (6) would be replaced by a siren. <IMAGE>

Title: Denture protection
Inventor: HARVEY WILSON
IPC: A61K8/04
Filed: 1989-02-13
Abstract: To combat the accumulation of plaque on dentures, a non self-supporting coating of a non-toxic, negatively charged polysaccharide is applied. The polysaccharide coating is gradually sacrificed or ablated during wear. Ablation appears to remove microorganisms along with coating material. The polysaccharide is further defined by an ability to reduce the adhesion of Streptococcus salivarius cells in a simple in vitro bacterial adhesion test by at least 25 % over a control.

Title: Method and apparatus for moving control points in displaying digital typeface on raster output devices
Inventor: KAASILA SAMPO
IPC: G06T11/20
Filed: 1990-04-27
Abstract: Method and apparatus for use in conjunction with a digital computer to provide improved font rendering capability including means in accordance with one typical embodiment of the present invention, for accepting an input representation of outlines of a font, which may be comprised of alphanumericals, non-Roman based characters, or any arbitrary symbols. Once received, a control program (1>MDAP-11>MIRP [01101] (24) within the computer memory displays and grid fits the outlines on an appropriate device, such as a raster (grid) scanned CRT, of the selected glyph. Control instructions incorporating scaling, interpolating, and grid-fitting techniques are available for a user to produce outline of typefaces at various sizes and resolutions. Grid-fitting is the alignment of control points (0-11, outer outline, 12-23, inner outline) in a digital outline description to a (raster, pixel) grid and other manipulation of the control point positions for the purpose of facilitating scan conversion outputs. …<??>Without the controlled resealing and shifting of (e.g. B-spline) control points, a letter O, designed in high-resolution, could appear distorted as in Fig 7 when converted to low resolution. 24 pixels in the improved O (grid aligned) are symmetrical. …<IMAGE>…

Patent GB-2250648-A (GB)
Title: Phase and frequency modulation signal generator
Inventor: SMITH CHRISTOPHER NIGEL
IPC: H03C3/09
Filed: 1990-12-08
Abstract: A phase modulation signal generator has a phase lock loop (PLL) which is capable of being locked to an external oscillator signal and to a phase modulation input signal. An integrator (8) may be provided to integrate a frequency modulated signal and cause the phase modulation signal generator to operate as a frequency modulated signal generator. The PLL has a phase sensitive detector (1), a summing circuit (2) which couples the modulation input signal to the loop, and a voltage controlled oscillator (5). The phase sensitive detector (1) has an input coupled to an inverter (7) for coupling the external oscillator frequency (6) to the loop. Control means (9, 10) is provided for determining when phase shift of the input signal reaches 180 DEG  and for triggering the inverter to invert the phase of the oscillator signal fed to the loop, each time such a phase shift occurs. In the case where the generator is operating as a frequency modulated signal generator, at the same time as the inverter is triggered the integrator (8) output is discharged to zero so that the summing circuit (2) output is unchanged. Thus the integrator can effectively ramp continuously and the modulator accommodate very low frequency modulation. The signal generator may be operated to produce MSK or GMSK signals. <IMAGE>
