Title: Expanding mandrels
Inventor: JOHNSON CYRIL
IPC: B23B31/117
Filed: 1983-09-19
Abstract: An expanding mandrel comprises a generally cylindrical body 21 for attachment to a rotation device, the body having an integral abutment portion 27a. A draw bar 22 passes axially through the body 21 and has at its outer end an expander 24. Resilient and flexible means comprising a generally cylindrical sleeve 23 and two resilient and flexible rings 25 are located around the body 21 between the abutment portion 27a and the expander 24. On movement of the expander towards the abutment portion 27a the sleeve, abutment portion and expander cooperate to deform the rings 25 outwardly to grip the inside diameter of a generally tubular work piece, which is to be machined, without distorting the work piece. <IMAGE>

Title: Optical device and reform fabrication
Inventor: PRESBY HERMAN MELVIN
IPC: G02B6/13
Filed: 1983-11-25
Abstract: A method of fabricating an optical device having a prescribed refractive index profile, comprises forming a surface with an initial refractive index formation and altering it by directing a laser beam onto the surface, either as it is formed or afterwards, so as to selectively evaporate material from a predetermined part of the surface. The refractive index profile of a growing soot form fabricated by the axial vapor deposition method is altered by evaporating the index modifying dopant from selected portion of the form. In an illustrative embodiment of the invention described, a laser beam (17) is used to "write" the desired pattern on the growing form (10). The technique can be employed to fabricate optical fiber preforms as well as two and three dimensional integrated optical devices and circuits. <IMAGE>

Title: Production of carboxylic acids from acyl fluorides
Inventor: CORN JOHN E
IPC: C07C51/12
Filed: 1984-02-09
Abstract: A carboxylic acid, e.g., isobutyric acid, is produced by reacting an acyl fluoride, e.g., isobutyryl fluoride, with less than the total amount of water required to hydrolyze all of the acyl fluoride to the carboxylic acid under conditions whereby the anhydrous acid, e.g., HF, forms. The acyl fluoride may be produced by reacting an organic compound such as propylene with carbon monoxide and an anhydrous fluoride acid. Hydrolysis takes place at 20 to 150 DEG C at a pressure of 1 bar to 340 bars. The ratio of anhydrous hydrogen fluoride to acyl fluoride is within the range 0.01 to 95.5 parts by weight anhydrous hydrogen fluoride to 99.99 to 4.5 parts by weight of the acyl fluoride.

Title: Producing an annular wedge for anchoring a tension element in prestressed concrete
Inventor: LANGWADT OTMAR
IPC: B23P13/00
Filed: 1985-07-18
Abstract: An annular steel wedge (2) divided into individual wedge sections (2a, 2b, and 2c Fig. 2, not shown) is used to anchor a tension element (1) in a prestressed concrete structure (4). Prior to forming the individual wedge sections from an axially extending annular wedge blank, the inside surface of the blank is threaded forming circumferentially extending teeth (11) so that the wedge can grip the tension element and provide the requisite friction coefficient in the anchorage. To prevent the sharp teeth formed in the threading step from cutting into the surface of the tension element, the teeth are ground down in a tumbling operation in which the wedge sections (2a, 2b and 2c) are mixed together with ceramic grinding bodies in a tumbling drum. The grinding bodies have bends in at least a portion of their surfaces and the bends have a smaller radius than the radius of the threaded inside surface of the wedge. <IMAGE>

Title: Method of making metal can ends with plastics closures
Inventor: BALL MARTIN FRANK
IPC: B65D17/00
Filed: 1986-09-16
Abstract: A method of making a metal can end with a tear-open plastics closure, for a can intended to be resistant to leakage when subject to internal pressures, such as arise from carbonation of a beverage or thermal processing, wherein the undersurface of the can end is provided with a plastics coating (14). and the can end is pierced to form an aperture (15) with a peripheral downturned flange (16) at an angle of 80° to 120° to the plane of the can end and having a flat end. A one-piece ring pull closure is injection moulded on to the can end (10) from a plastics material resistant to softening at up to at least 65°C, without additional heating of the metal, so as to fill the aperture (15), bond with the coating (14), and enclose the flange (16), with a residual thickness below the flange of 0.08 to 0.5 mm. The thickness of the plastics material of the closure is such that it can be sheared against the flange when the ring pull (26) is pulled manually. The residual thickness of the plastics material may be varied around the aperture to increase resistance of the closure to creep, and the aperture may be pear-shaped or may be circular with a separate vent hole.

Filed: 1986-11-13
Abstract: To determine the position of an object P within a designated area 16, a plurality of radiation generators D1,D2 in an array 12 of generators bounding the area 16 are sequentially activated, and radiation detectors PT1,PT2 in an array 14 of detectors on the opposite side of the area 16 detect the resultant shadows for each generator D1 ,D2 activated. The number of times each detector PT1,PT2 detects a shadow, during the sequential activation of the generators D1,D2, is summed, and the detector for which that sum is maximum corresponds to the position of the object P in the direction parallel to the array 14 of detectors. This is repeated for a second array 13 of generators, and a second array 15 of detectors, thereby to determine the position of the object P in the direction parallel to the second array 15 of detectors. From these two position detections, the position of the object P is unambiguously determined. <IMAGE>

IPC: G08C23/04
Filed: 1987-12-24
Abstract: A data communication system provides communication between a plurality of controlled equipments (1) (powered by synchronised a.c. power signals) and respective remote controllers (3). The period of one a.c. power cycle is notionally divided into a plurality of time slots and each equipment and its associated controller is assigned one or more of these time slots. A microprocessor (5) at the equipment times the appropriate delay between a synchronisation signal and the respective time slot. The synchronisation signal may be derived from the a.c. power signal. Data, including an identification signal, is then transmitted to the associated controller. The controller having received the data from the equipment then re-transmits the identification signal and transmits command data. If data is not received within a certain time by either the equipment or the controller an indication of failure is generated. <IMAGE>
