Patent GB-2173838-A (GB)
Title: Fire-resistant enclosures
Inventor: SHARP MICHAEL FRANCIS WARREN
IPC: E05G1/024
Filed: 1986-04-07
Abstract: The apron sections 12 and 14 in the body and door of a data cabinet are made from steel strips having rows of elongate slots 17 running in the circumferential direction of the closure with the slots in adjacent, rows displaced in pitch, These slots thus lie across the temperature gradient from the external skins 2/8 to the internal skins 1/7 of the body and door so that the heat conduction pathways across the aprons are long and tortuous, thus reducing the rate of heat inleak to the cabinet while retaining sufficient structural rigidity in the closure region. <IMAGE>
Patent GB-2190187-A (GB)
Title: Optical fibre sensors
Inventor: EPWORTH RICHARD EDWARD
IPC: G01H9/00
Filed: 1986-05-09
Abstract: An array of optical fibre sensors comprises an optical fibre structure having a series of reflective discontinuities formed by spaced fusion splices between fibre elements of different refractive indices. The structure may comprise a number of equal long lengths of fibre 4 of one refractive index joined by short lengths of fibre 5 of a different refractive index. One end of each short length is fully fusion spliced to one long fibre length (no reflective interface) whilst either the other end is partially fusion spliced or an index matching medium is disposed between the other end and the other long length in order to obtain a single reflective interface. Alternatively, alternate long lengths of fibre (6,7) with different refractive index may be partially fused together at their ends to form reflective interfaces (8). Pairs of laser pulses of slightly different frequency passing along a fibre having equally spaced reflective interfaces are partly reflected to a detector where they are heterodyned to detect phase shifts due to deformation forces (eg acoustic waves) acting on the fibre. <IMAGE>

Title: Piston dosing pump
Inventor: ALBARDA SCATO
IPC: F04B13/00
Filed: 1986-10-03
Abstract: A pump for delivering accurately a measured quantity of a fluid e.g. or anaesthetic comprises a piston 11 in a cylinder 10, each of which is reciprocated by eccentric drives 16, 17. Into pump space 9 there open the inlet valve 10, 13 and outlet valve 6. From the position immediately after discharge, with piston seal 14 abutting surface 30, the sequence is as follows:    -cylinder 10 is depressed to open valve 10, 13,    -piston 11 is then retracted to draw in a measured dose of fluid,    -cylinder 10 then rises to close valve 10, 13 and then,    -piston 10 goes through its discharge stroke. The valve 10, 13 is not as narrow as usual and so avoids throttling on the intake stroke with the consequences of vapour lock and incomplete filling of the pump chamber. There may be, as is shown, a disc valve 4 after the ball valve 6. <IMAGE>

[Also in Group XXIX] In a hydraulic motor or pump having radially disposed cylinders and pistons mounted to be operated from a shaft 7, Fig. 2, having an eccentric 8, the eccentric rotates relative to the bore 9 of a five-sided bearing block 10, Fig. 1, which operationally engages hollow pistons 11 loaded by springs 13 without the intervention of a mechanical connection. The block is formed with arcuate grooves 18, 19 to which pressure liquid is admitted to one and exhausted from the other through longitudinal shaft ducts 22, 23 connected through annular recesses 24, 25 and radial ports 27, 28 in a sleeve 26 with. pipe connections 30, 31. The sleeve 26 surrounds one end of the shaft 7 and is fitted with seals 29 to take up any wear or misalignment that may occur. The block 10 is also formed on. each of its faces with a recess in which is mounted a pressure retaining ring 15. The rings have an effective diameter not greater than that of the cylinders and are subject to liquid pressure on their rear faces so that they " float " in their respective recesses. The springs 13 urge the pistons 11 into sealing contact with the rings. Pressure liquid may be admitted to either arcuate groove depending upon the position of a change-over valve (not shown), the other groove being connected to sump. The casing 1 is connected to a drain port 32 through axial and radial ports in the shaft 7. Instead of the shaft 7 rotating on reciprocation of the pistons 11, the shaft may be held fast and the casing 1 together with the cylinders and pistons rotate. In a modification, the cylinders 11 may be formed in the bearing block 10 in which case the pressure retaining rings 15 are housed in recesses in blocks secured to the casing. The rings may alternatively be housed in recesses in the abutment faces of the pistons and be urged by the springs against plane faces of the block. Grooves 41, Fig. 3, through the ring control the pressure gradient across its face.

Title: Control of oscillators
Inventor: BERLINER SHLOMO
IPC: H03L1/02
Filed: 1990-08-30
Abstract: There is provided a system for automatically and integrally calibrating an oscillator 10 to achieve frequency accuracy and stability in a radio, particularly a radio where the temperature of an oscillator can be set. For calibration or setting up of an oscillator 10 subject to error in output frequency, the radio is tuned to a calibration frequency received from a transmitted frequency standard or a precision test instrument. The frequency error of 10 is multiplied as a result of conversion to the baseband via mixers 14, 16 and a demodulator 20. The baseband frequency is measured by digital frequency sampling in a microprocessor included in a processor 18. The microprocessor applies frequency control signals to the oscillator 10 via a D/A converter until the frequency deviation measured at the demodulator 20 output disappears. The final output of D/A converter is stored in a non-volatile memory. The oscillator 10 may be an oven temperature controlled crystal oscillator. <IMAGE>
