IPC: C07C17/154
Abstract: 938,096. Ethyl chloride. PITTSBURGH PLATE GLASS CO. May 1, 1962 [May 16, 1961], No. 16545/62. Class 2(3). Ethyl chloride is produced by reacting ethane and an oxygen containing gas with chlorine and/or hydrogen chloride in the presence of an oxychlorination catalyst at below 360‹C., the feed rate of reactants, f (in litres per minute) and the weight of catalyst, w (in grams) are controlled to provide a w/f ratio of above 30, and the molar ratio of oxygen to the chlorinating agent is 04:1 to 24:1. The catalyst may be a halide of a metal having a variable valency, e.g. copper chloride, which may be used with halides of other metals, e.g. alkali or alkaline earth metals. The catalyst may be impregnated on a carrier or supported and used as a fixed or fluidised bed. The reaction is preferably carried out in a tubular reactor with a length of 8 to 600 times its internal diameter, which may be from “ to 8 inches. The reactor may be jacketed and cooled, or a coolant, e.g. water, may be sprayed directly into the reactor. The molar ratio of chlorine to ethane may be from 0À3:1 to 2À0:1 and the molar ratio of hydrogen chloride to ethane from 06:1 to 4À0:1.

Title: Vibrator apparatus
Inventor: HAMER ARTHUR
IPC: B65G27/32
Filed: 1994-08-26
Abstract: A vibrator apparatus for vibrating an elongate beam 2 includes a reaction member 5 connected by resilient mounting assemblies to the beam. The source of the vibrations is preferably an electromagnetic device 16 located between the beam and the reaction member. At each end of the beam is a weight 13 which is positioned below the neutral axis of the vibrator axis and is adjustable in a direction normal to the length of the beam so as to modify the vibrational movement of the beam. On the upper surface of the beam a conveying surface for objects 33, for example, nuclear fuel pellets, is formed by a multiplicity of inclined fibres packed in a backing. In operation, vibration of the beam causes an object supported on the fibres to move along the beam in the direction of fibre inclination. <IMAGE>

Title: Sequential steam valve
Inventor: HEMSLEY PHILIP DAVID
IPC: F16K11/02
Filed: 1994-12-02
Abstract: In a sequential steam valve, a piston closure member 25 runs in the bore of a tubular insert 26. Annular seating 29 on the end of the piston 25 co-operates with seating 30 in the valve body to seal steam inlet port 21. As the piston member 25 is moved away from the seating 30, so it progressively uncovers a first opening 27 in the insert, thereby progressively admitting steam to first outlet port 22. Further movement progressively uncovers second opening 31, thereby progressively admitting steam to second outlet port 23. This allows both nozzle and throttle control of a steam turbine to be performed using a single valve. At least one further outlet port may be provided at the same position as at least one of the outlet ports 22, 23. A modified insert provides an annular space about the seating 30, allowing steam for the first opening to flow over the entire periphery of the seating 30. <IMAGE>

Title: Absorbent article
Inventor: WIDLUND URBAN
IPC: A41B/
Filed: 1995-02-24
Abstract: An absorbent article such as a diaper or incontinence guard has two openings 15, 16 in the top-sheet, one for urine and one for faeces. A piece of flexible material lies transversely across the diaper between the openings, located between the absorbent body and the top-sheet and acts as a barrier to prevent the waste products mixing. The top-sheet is only joined to the diaper at its edges and, after manufacture, elastic threads 10, 11, 24, 25 act to bring the diaper from the flat state of Figure 2 to the relaxed state of Figure 1 where the top-sheet is distanced from the absorbent body. This also causes the flexible material to unfold or rise to form the barrier. The barrier may take varied forms. <IMAGE>

Title: Semiconductor device having contoured package body profile and method for its fabrication
Inventor: WOOSLEY ALAN H
IPC: H01L21/56
Filed: 1996-08-30
Abstract: An overmolded semiconductor device (30) has a contoured package body profile instead of a conventional flat package body surface for uniform filling during the molding process. A cross-section of the semiconductor device reveals a substantially uniform thickness of plastic (36 and 38) covering the carrier substrate (14) and overmolding the semiconductor die (12). Alternatively, a thicker layer of plastic overmolds the semiconductor die than the layer of plastic covering the carrier substrate. The contoured package body profile is designed to allow a uniform flow front progression of molding compound during the molding process to eliminate voids in the package body by providing the same resistive pressure to the molding compound flow front during filling. The plastic body may have curved or straight contoured edges.

Title: Screens for use by occupants of vehicles
Inventor: PAYNE STEPHEN JOHN
IPC: B60J3/04
Filed: 1996-12-13
Abstract: A screen (1), carried by a mounting (2) of articulated form, is for use by an occupant, (usually the driver), of a road vehicle and is inherently capable of reducing the effects of unwanted light, such as the headlights of on-coming road vehicles, travelling from external the road vehicle, towards the eyes of the occupant, so as to shield the eyes of the occupant. The articulated mounting (2) enables the screen 1 to be moved from a passive mode to an active, eye-shielding mode. Various forms of screen are disclosed including hollow screens containing liquid crystal material, and operable under the influence of an electric field, to cause the screen to become sufficiently opaque to reduce the effects of the unwanted light.

Title: Encoder for detecting forward/reverse rotation
Inventor: NOMURA HIROSHI
IPC: G02B7/10
Filed: 1997-01-24
Abstract: An encoder 901 has a rotatable shaft A with two rotating disks 59a, 5b provided thereon. Each rotating disk is formed with a pattern of slits S or reflective areas. Respective photosensors are associated with each disk 57a, 57b and are mounted on a common surface. As the disk rotates, output signals are produced by the photosensors according to the variation in the intensity of light reflected or transmitted by the pattern. The angular relationship between said disks is selected to provide, on rotation thereof, output signals which have a predetermined phase difference, eg a quarter phase difference, to enable the direction of rotation to be determined. The encoder may be used to determine the amount, speed and direction of rotation of motor driven mechanisms in a zoom lens camera.

Title: Tracking cache misses in out-of-order instruction execution
Inventor: LESARTRE GREGG
IPC: G06F12/08
Filed: 1997-02-07
Abstract: A miss tracking system (100) optimizes the bandwidth to a main memory associated with a processor that utilizes a data cache (24) and that executes instructions out of order. The processor has a memory queue (MQUEUE) (38b) (Fig 1) for receiving and executing instructions that are directed to memory accesses to the cache or the main memory. The MQUEUE includes mechanisms (39b) for receiving and executing respective memory instructions out of order. Each mechanism includes an instruction register for storing an instruction and an address reorder buffer slot (ARBSLOT) (48) for storing the data address of the instruction execution results. Significantly, dependent-on-miss (DM) indicator logic (135) in each ARBSLOT prevents a request from its respective ARBSLOT to the main memory for miss data that is absent from the cache when another ARBSLOT has already requested from the main memory the miss data. This is accomplished with the DM indicator logic and a status indicator (82) associated with each cache data line. The DM indicator logic provides a signal DM to indicate whether or not an instruction associated with its respective ARBSLOT currently depends upon miss data not yet received. The status indicator indicates that the corresponding cache data line is both invalid and has already been requested from the main memory.
