Title: Improvements in or relating to lining elements for tunnels or shafts
Inventor: MCBEAN RUPERT JOHN SIDNEY
IPC: E21D11/08
Filed: 1988-09-19
Abstract: The disclosure relates to a shaft lining comprising precast concrete arcuate lining elements including a pair of special lining elements (11) to provide an access point for a horizontal tunnel. Each element (11) comprises an outer section (12) cast in high compression strength high impact strength steel reinforced concrete with a semi-circular shaped recess (13) in which a lightweight concrete wall section (14) is cast with an integral flange (15) along the diametrically extending edge thereof to abut with the corresponding flange (15) of the adjacent segment when erected. The two elements (11) are secured together by a fixing bolts (17) and (20). The lightweight concrete circular wall formed by the two semi-circular sections (14) within the elements (11) supports the wall of the encircling shaft during erection of the shaft but can readily be broken out when connecting the shaft to a tunnel loading from the shaft. <IMAGE>

Title: Method of attaching a female element to a panel
Inventor: MULLER RUDOLF
IPC: B21D28/32
Filed: 1988-10-19
Abstract: A method of attaching a female element having an annular riveting portion to a panel and the installation apparatus. The method includes driving a punch through the female element into a panel supported on a die member forming an unsupported cone-shaped panel portion in the cavity of the die member. The punch includes an axially extending piercing end which pierces a small opening in the cone-shaped panel portion and an arcuate drawing portion which is driven against and through the panel opening, enlarging the panel opening. The annular riveting portion of the female element is then driven into the cone-shaped panel portion and through the panel opening, drawing the panel portion into a tubular shape engaging the external surface of the riveting portion. Finally, the riveting portion is driven against a center post of the die member, radially outwardly deforming the free end of the riveting portion and forming a mechanical interlock with the tubular panel portion. In the preferred embodiment of the die member, the center post includes an axial bore and is spring biased through an opening in the bottom of the die cavity to receive the slug pierced from the panel by the punch. The center post is then resiliently biased downwardly to mate with the die cavity during radial deformation of the riveting portion of the female element.

Filed: 1988-11-14
Abstract: PCT No. PCT/GB88/00984 Sec. 371 Date May 1, 1990 Sec. 102(e) Date May 1, 1990 PCT Filed Nov. 14, 1988 PCT Pub. No. WO89/04259 PCT Pub. Date May 18, 1989.The reinforcement for the bead of e.g. a pneumatic type, a rolling lobe diaphragm or an air spring is constructed by winding onto a mandrel or former superimposed layers alternately of unsheathed wire and flat, uncured rubber strip. Rubber is wound on before wire winding commences and continues after wire winding stops, so that the assembly exposes no cut wire end. After the winding operation the assembly is subjected to heat and pressure with all the wire embedded in and surrounded by an integrated, vulcanized rubber body. The rubber layers may be parallel with and on opposite sides of the layers of spaced wire windings or a given rubber winding may have wire windings on its radially opposite sides. The windings, both of rubber and wire, may be discrete loops or may be made by helically winding a single rubber strip or wire. The shape of the assembly as well as the volume of rubber at any position therein may be controlled by varying the tension under which the rubber strip and/or the wire is wound.

Title: Production management system and method of transmitting data
Inventor: SHIMANAKA CHIKAFUMI
IPC: G05B19/418
Filed: 1989-12-18
Abstract: A production line such as an automobile assembling line includes a plurality of slave computers 18 for controlling (for instance) assembling robots RB in assembling stations ST, and a host computer 16. When common information required by the slave computers is to be modified, e.g. due to a change in the robots, common information stored in the host computer 16 (at 52h) is modified and transmitted to the slave computers. As described, workpieces, eg car bodies W, carry identifying bar codes which are read to initiate the transmission of corresponding workstation command data from a store 50 of the host computer 16. Also as described, the slave computers 18 add serial numbers to the data they receive. On subsequent transmission, the host computer 16 checks the serial numbers and requests the host computers 18 to transmit any missing data. <IMAGE>

Title: Visual inspection of fabric faults
Inventor: TIPLER ROBERT JOHN
IPC: G01N21/898
Filed: 1990-05-11
Abstract: Fabric inspection apparatus comprises a screen (7) or wire frame spreader (60), preferably elliptical in shape, over which fabric (1) is drawn as it is wound onto a take-up roller (3). The screen (7) or spreader (60) is supported on rollers (5), through the fabric (1), and is lightweight in construction containing no light source. Light is transmitted to the interior of the screen or spreader, for illumination of the tubular fabric (1) from within the tube, by shining light from a light source (12) through one ply of fabric and through the top (9) or bottom of the spreader or of the screen which is transparent. Illumination is more uniform than if the light source were mounted within the screen or spreader; the handling is easier because the screen or spreader can be made light in weight; the strain on the fabric is less; and problems in powering the light source are solved.

Patent GB-2248684-A (GB)
Title: Optical sensing systems
Inventor: LAMB CHRISTOPHER
IPC: G01H9/00
Filed: 1990-10-12
Abstract: An optical sensing system comprises a laser (1) which illuminates an acousto-optic modulator (11) with a continuous light beam (10). The modulator (11) is driven by pulse pair (F1-F2) to deflect the beam to optical sensor array (15). When the modulator (11) is not driven, the light beam passes through and is reflected by mirrors (21, 22, 23 and 24) back to the modulator (11) where it is deflected to optical sensor array (26). The arrangement therefore enables one acousto-optic modulator (11) to drive more than one optical sensor array.

Title: Transceiver having a feedback loop
Inventor: SMITH CHRISTOPHER NIGEL
IPC: H04B1/40
Filed: 1991-11-08
Abstract: The receiver forms part of a feedback loop, and generates a feedback signal which is applied to the transmitter. To generate a GMSK signal at 1.8 GHz, as required for PCN, a low frequency vector modulator output must be frequency translated. A preferable technique for translation is to use a phase locked loop incorporating a downconversion mixer within the loop to define an upconversion transmitter. In the present invention, the downconversion mixer in the receiver 'front-end' is also used as the transmitter phase looked loop mixer. The additional cost of, power consumption of, and space occupied by a separate mixer is thus avoided. <IMAGE>
