Patent GB-2097120-A (GB)
Title: Flame detector
IPC: G01J5/60
Filed: 1982-04-13
Abstract: A flame detector includes a non-microphonic infra-red sensor 7 having a broad band frequency response. To maximise sensitivity to radiation from flames in the 4.3  mu m solar absorption band a narrow band optical interference filter 6 is transmissive in a band having preferred limits of 4.54  mu m to 4.38  mu m, the filter being chosen such that the integrated solar energy transmitted thereby is less than an alarm threshold. A filter 9 prevents re-radiated heat from filter 6 reaching the sensor 7. A filter 10 prevents radiation of wavelengths less than 4.38  mu m from reaching the filters 6 and 9 reducing heating thereof and also provides a series of filters to stop direct broad band transmission to the sensor through pin holes in the filters. A signal processor 11 detects flames by virtue of the flame flicker frequencies and includes provision for compensating for the effects of low frequency components on the amplitude of radiation produced by flames. <IMAGE>

Title: Information-indexing machines
Inventor: HOOKWAY ALAN FREDERICK JOHN
IPC: G06F17/30
Filed: 1982-10-28
Abstract: A data structure for a particular application, for example the enrolment record of a college, is entered into a machine by plotting an appropriate structure diagram 1 on a display of the machine using an appropriate keyboard. The structure diagram 1 comprises labels within boxes 2 denoting the types of data entry which it is intended to index, and links 4 joining the boxes 2 and denoting the relationships between the different types of data entry. When the design of the data structure diagram 1 has been completed the form in which the indexed data is to be displayed on entry and retrieval is determined by designing one or more dummy forms. When data is subsequently entered into the machine and retrieved using the forms, the data is automatically indexed and the indexed data is selectively displayed in dependence on the previously design data structure diagram 1. Furthermore it is a straightforward matter to modify the manner in which the data is indexed by the machine by changing the data structure diagram 1. <IMAGE>

Title: Binding memory contents into machine registers
Inventor: DITZEL DAVID ROGER
IPC: G06F9/44
Filed: 1983-02-21
Abstract: The local variables of procedures are automatically mapped form main memory of a computer into a circular buffer comprising machine registers. As instructions are fetched from the main memory, the instructions are partially decoded by adding the stack pointer to the offset and then stored in an instruction cache. In cases where the sum of the memory locations required by the procedures exceed available register memory, the contents of the registers nearest the maximum stack pointer are flushed back to main memory.

Title: Chemical analysis
Inventor: VOUTILAINEN REIJO ANTERO
IPC: G01N21/53
Filed: 1983-05-26
Abstract: In a method and apparatus for carrying out a chemical analysis by a measuring principle based on light on a sample placed in a cuvette (1), the measuring is carried out using at least one detector (4, 5) both along the direction of the incident light (6) and at an angle thereto. In order to reduce or eliminate the disadvantages of several different measuring principles, the cuvette (1) is placed in an opaque sleeve (2) having openings (3) for light, and the basic idea is to bring the sleeve (2) with its cuvette (1) into rotary motion in relation to a source (11) of light and the detector/ detectors (4, 5), in which case the light arrives at the detector(s) intermittently. In order to eliminate errors, the signal of one detector is preferably divided by the signal of the other detector. Alternatively, the sleeve and cuvette may be maintained stationary, the light source and detector(s) rotating therearound. <IMAGE>

Title: Process for sealing facade structures and means for carrying out the process
Inventor: GARTNER DR FRITZ
IPC: E06B7/14
Filed: 1983-07-27
Abstract: With this process air from the outside is delivered under pressure, as by a fan 20, between the outside wall of the building and the facade structure 10, 12, 14 so that it can flow out again through any leaks in the structure and blow away any water collecting on the outside of the structure 10, 12, 14. This avoids the formation of any icicles on the outside of the structure 10, 12, 14 at low temperatures in addition to which the facade jointing structure can be made to greater tolerances. The process is suitable both for a facade structure subsequently fitted in an existing building and also for employment in new buildings. <IMAGE>
