Patent GB-2232023-A (GB)
Title: Analogue-to-digital converter
Inventor: THURSTON ANDREW MARK
IPC: H03M1/12
Filed: 1990-04-24
Abstract: Analogue signals at i/p are converted to digital data at o/p by means of a Sigma-Delta modulator comprising a pair of bandpass filters H1(s), H2(s) and a feedback loop including DAC 22. The tendency of such a circuit to instability is reduced or eliminated by making small variations in the phase of the block 1 controlling the feedback pulses relative to the clock 2 controlling the data output pulses. As an alternative, corrections may be made to the feedback pulses by an additional feedback loop providing pulses for correcting the feedback pulses. <IMAGE>

Title: Holographic data storage systems
Inventor: WEBSTER SIMON CHARLES
IPC: G03H1/00
Filed: 1990-07-13
Abstract: A system for the storage of visual information comprises a first optical arrangement 6 consisting of a number of phase retardation plates 1, 2, 3 arranged in series, each plate comprising an array of liquid crystal cells. The phase shift produced by the cells can be set to produce a pattern of different phase shifts from cell to cell across the plate. Light from an image 4 representing the input information is directed through the plates so that a modified image is produced. This is recorded holographically. A second optical arrangement, or the first arrangement in reverse, is used to reproduce the input image from the stored modified image. <IMAGE>

Title: Mold tool for consolidating composite materials
Inventor: PRATT RICHARD DAVID
IPC: B29C43/36
Filed: 1990-12-19
Abstract: A curved composite fibre reinforced material body (80) is consolidated to a complexly curved shape by placing rigid tooling (88) on the concave-facing side of a region of the body, and a fluid pressure applying membrane (92) on the other (convex-facing) side of the body. In another region of the body where the sign of the curvature of the body changes so that the other side becomes the concave-facing side, the rigid tooling (86) is placed on that concave-facing side, and a fluid pressure applying membrane (90) is contacted to the convex-facing side. The rigid tooling avoids wrinkling, or bridging of reinforcement fibre lengths, that would otherwise arise in concave regions e.g. inside corners, from pressure applied by a membrane to reinforcements, of lengths which are respectively too great, or too small, to span the corner. <IMAGE>

Title: Method for manufacturing photoconverter
Inventor: MAKOTO TOHO
IPC: C09K11/02
Filed: 1991-01-21
Abstract: A method for manufacturing a photoconverter comprises the steps of forming a sol by obtaining a mixture solution of a matrix compound capable of forming a sol-gel film containing a matrix substance component permeable to visible light and an acid chloride or nitrate containing luminous atoms, forming the sol into a coating over a substrate comprising a glass tube, and subjecting this coating to a reduction by means of a calcining to have the coating sintered to obtain the photoconverter. The method makes it possible to manufacture a photoconverter which is easy to use substantially to the same extent as a fluorescent substance and is capable of executing photoconversion at high efficiency. <IMAGE>

Title: Microhardness tester
Inventor: TOBOLSKI EDWARD
IPC: G01N3/48
Filed: 1991-03-27
Abstract: A microhardness tester comprises a turret (21) capable of holding a plurality of load rod assemblies (23, 31) and optical objective elements (24-26), each of the latter being aligned with respect to the indenter of one load rod assembly desired to impinge upon a specimen to test for microhardness, whereby on changing the load rod assembly to change scales for the testing, it is only necessary to properly align the indenter of the second load rod assembly and not the objective elements with the test specimen. The load rod assembly (20) of the microhardness tester free falls in its testing mode, a spring (4) retaining the rod before testing. Thus, the load weights (94) applied to the load rod are not affected by spring load tolerances allowing calibration to be completed during the weight manufacturing process. <IMAGE>

Patent GB-933988-A (GB)
Abstract: 933,988. Electric selective signalling. SOC. DE MECANOGRAPHIE JAPY. June 5, 1961 [June 20, 1960], No. 20239/61. Class 40 (1). [Also in Group XIX] In apparatus comprising a calculating machine electrically connected for reading out purposes with a typewriter having solenoids for operating the number keys and space bar, the digits are read out denomination by denon- ination and this serial read out is controlled by a multivibrator. Actuating racks or the like in the calculating machine differentially position bridging contacts P along denominational bars B1 to B13 so as to connect these bars with perpendicularly arranged bars Do to D9 and DBE connected to the number key and spacebar solenoids L0 to L, and LBE of the typewriter. A multivibrator comprising transistors Q1 and Q2 is energized on depression of the total or sub-total keys T, ST of the calculating machine and causes a switch arm 4 to be stepped round from the rest position shown. Contacts 6 then hold the circuit for the multivibrator. The first contacts P1-P3 merely ensure that stable conditions are established and the next contacts P4-P6 are effective only if a switch 10 is actuated in the calculating machine to indicate a negative total, in which case they are connected to the space solenoid to cause several spacing movements so as to offset the printed total. The remaining contacts P7 to P23 are connected to the denominational bars B13 to B1 for the printing of the digits, or to the space solenoid so as to produce a space between each group of three digits. Other contacts may be connected to solenoids for punctuation purposes.

Title: Installing pipe liners
Inventor: AZIZ MOHAMMED YUNIS
IPC: F16L55/28
Filed: 1995-06-12
Abstract: Sensor apparatus 18 for use in installing a plastic service pipe 16 inside a steel service pipe 10 connected to a main 14 consists of a flexible element 42 which is fed through the steel pipe 10 and through the plastic pipe 16. The element has at its remote end two light-emitting diodes 80 and two photoconductive cells 82. The flexible element and the pipe 16 are fed together into the steel pipe 10. The sensor 18 detects when the cells 82 have entered the main 14 because the intensity of the light reflected to the cells 82 falls to a low value, and a warning signal is given. This also indicates that the end of the plastic pipe 16 which carries a seal 38 is positioned correctly and that sealant 30 can be injected into the space between the steel pipe 10 and the plastic pipe 16. After the sealant 30 has been injected the sensor apparatus 18 can be recovered by withdrawal through the nose-piece 32 and through the pipe 10. Sensor 152 comprises further light emitting diodes and photoconductive cells and detects the presence of sealant at the remote end of the steel pipe 10 by monitoring light reflected from the steel pipe.
