Patent GB-2197717-A (GB)
Title: Displacement detection
Inventor: HENDERSON PHILLIP JAMES
IPC: G01D5/26
Filed: 1987-10-21
Abstract: Apparatus for determining displacement of an object comprises a light source (1) for propagating polychromatic light along a path to a detector (7). Radiation modulation means such as a filter (5) is provided in predetermined fixed location with respect to the source (1) and the path of the light is adjusted in response to a displacement of the object such as to vary the distributed spectral content of the light reaching the detector (7).

Title: Medication dispensing systems
Inventor: MCLAUGHLIN JOHN
IPC: A61J7/04
Filed: 1987-11-02
Abstract: An improved medication dispensing system is provided for controlled preprogrammed dispensing of medication to a patient and for creating a retrievable patient medication record. The system includes a dispensing unit located, for example, at patient bedside within a hospital room or the like and adapted to receive a pair of medication canisters having magazines with individual cassettes which have been preloaded in a preprogrammed manner in the hospital pharmacy or the like respectively to contain scheduled and unscheduled medications for administration to the patient. The dispensing unit is programmed according to individual patient needs to signal a nurse or other personnel at selected times when scheduled medication is prescribed, whereupon the scheduled medication can be accessed for dispensing only after entry of valid nurse or other personnel identification code into a dispensing unit memory. The unscheduled medications may be accessed by the nurse or other personnel in a similar manner but on an untimed basis as required by the patient. The dispensing unit further includes sensors for detecting removal of any medication cassette and for signalling the dispensing unit memory to create a corresponding patient medication record. A data transmission device is provided for selectively programming the dispensing unit memory and/or for reading the patient medication record from the memory.

Title: Linear force from rotating system
Inventor: STRACHAN JOHN SCOTT
IPC: F03G3/08
Filed: 1988-02-19
Abstract: A pair of flywheels (30) acting as gyroscopes are rotatably mounted on shafts (32) spun by motors (44) and flexible drives (46, 48). The shafts (32) are journalled in arms (38) pivoted to a central shaft (42) driven by a motor (52) via a worm drive (54, 56) which constrains the central shaft (42) to a constant rotational speed. The natural tendency of the flywheels (30) to precess upwardly is controlled by a cam (58) which allows the flywheels to rise slowly and then forces them downwardly. In another embodiment the flywheels are constrained to precess in a plane, and a mechanism is provided for forcing variations in their precessional speed. In both instances, a net linear thrust is produced. <IMAGE>

Title: Data carriers
Inventor: DRINKWATER KENNETH JOHN
IPC: G03H1/10
Filed: 1989-06-08
Abstract: A process for the manufacture of coded arrays of holographic optical elements (HOEs) (1) for use on data carriers (2) involves the creation of a master hologram (4), different portions (5) of which are constructed to diffract incident light into different selected directions into a recording medium (2) for interference with a reference beam (3), the reference beam being spatially modulated by a mask (6) comprising a coded array of discrete transparent areas. In this way a large number of different coded HOE arrays (1) wherein respective HOEs diffract in different directions, can be produced from only one (or a limited number of) master hologram(s) (4) in conjunction with differently coded masks (6). The recording medium (2) can be caused to swell in order to change the reconstruction wavelength of the HOEs (1) formed therein. Modifications are described. <IMAGE>
