Patent GB-2241931-A (GB)
Title: Roller conveyor
Inventor: CHO CHEON-EOK
IPC: B65G13/07
Filed: 1991-03-06
Abstract: In a roller conveyor which includes a plurality of rollers (1) for transferring articles and driving means eg endless belt 3 for rotating the rollers (1), each of the rollers (2) comprises a centrally disposed driving member (1b) to which rotational force from the driving means is transmitted and a pair of outer transferring members (1c) on which the article is supported. the driving and transmitting members being frictionally and resiliently coupled to each other by a coupling means, eg by fluorin resin bushing 6 and compression spring 4. The transferring members (1c) normally rotate along with the driving member (1b) but slide with respect to the driving member (1b) when the article is stopped, thereby preventing the abrasion of the transferring members (1c) of the roller (1). Thus, maintenance expenses of the roller conveyor and the time required for the repair are significantly reduced. <IMAGE>

Title: Sealing and making connection to electron tube devices.
Inventor: SJOBERG ERIC JAMES
IPC: C04B37/00
Filed: 1991-08-02
Abstract: A method of assembly of evacuated electron tube devices, such as image intensifiers has external electrical contacts each connected to a conductive layer or electrode contained within the vacuum envelope of the device by means of a conductive film layer 28, 30, 32 or 34 on a predetermined portion of a surface of an electrically non- conductive component e.g. ceramics 4, 6 or 8 or windows 10 or 24 to form a conductive "feedthrough", applying a solder glass to both a predetermined portion of the conductive film layer and to a portion of the surface of a second of the electrically non-conductive components and connecting the two components by adhering the layers of solder glass under temperature and applied pressure, e.g. below 450 DEG C. The conductive film layer is formed of a paste formed from a mixture of fine particles of metal or alloy and fine particles of glass frit suspended in an organic medium which is heated to around 900 DEG C. Alternatively the two components may be connected using low melting point alloy in place of the solder glass, a foil washer or paste layer of the alloy being placed between two previously metallised ceramic surfaces and then heated sufficiently in a suitable atmosphere to solder the components together. <IMAGE>

Title: Handling events in multiple processes.
Inventor: BELLE PETER VAN
IPC: G06F9/48
Filed: 1992-01-22
Abstract: A method is disclosed for carrying out a large number of processes, each of which may be quite complex. Initially, a record is created for each process, and a record is created for each event which may possibly be implemented for the processes. Data received at an input device is automatically written to the relevant process record and data inputting takes place for a pre-set time period. Each process is carried out by the output device implementing a pre-set initial event for the process, 22, and then, after a delay defined in the event record, 23, selecting the next event 27, depending on recorded conditions. The next event may, therefore, be a an override succeeding event, a logical succeeding event, or an alternative event, depending on both user requirements and on progress of the process as indicated by received values for variable parameters. Thus, complex processes may be dealt with without the need for the large processing delays associated with hierarchial processing. <IMAGE>

Title: Vehicle locking systems
Inventor: WALLINGTON GRAHAM
IPC: H01H11/00
Filed: 1992-02-22
Abstract: A multi-purpose switch assembly (10) used in combination with a latch assembly as part of a vehicle central door locking (CDL) system incorporates a switch shaft (14) whose inner end is provided with camming formations co-acting with switch contact blades protected within a housing. Actuating levers are selectively interchangeably mountable on the shaft (14) outside the housing enabling a standard switch assembly to be readily adapted to different CDL operating modes. Thus the shaft may carry a first lever (44) in positive drive engagement with the shaft and directly coupled to a latch lever (42) of the latch mechanism so that the switch contacts are operated whenever locking or unlocking movement takes place. The shaft can also carry a separate key operated lever (52) not directly drivingly engaged therewith or with lever 44. Alternatively the shaft may carry a single lever serving as the key lever of the latch mechanism so as to be movable on actuation of a door key independently of any motion of the latch mechanism. The single lever has lost motion engagement with the shaft so that the shaft is only displaced during part of the full range of movement of the lever to provide for a second switching mode. <IMAGE>

Title: Waterheating system
Inventor: GRIFFITHS RICHARD MARTYN
IPC: F24D3/10
Filed: 1992-03-31
Abstract: An unvented mains pressure hot water storage cylinder (1) includes an internal "bubble top" (19) defined by a separately formed chamber (18) for accommodating expansion of the secondary hot water (2) contained in the cylinder. This dispenses with the need for the expensive, cumbersome external diaphragm-type of expansion vessel conventionally used and avoids the potential problems associated with alternative internal bubble top arrangements in which the cylinder itself serves to trap the air bubble. The chamber (18) may be located within the bounds of heat exchanger (13) and secondary water may enter the cylinder (1) via the chamber (18). <IMAGE>

Title: Quench-hardening testing method and apparatus.
Inventor: FURUMURA KYOZABURO
IPC: G01B21/08
Filed: 1993-02-05
Abstract: A quench-hardening testing method and apparatus in which the quench-hardened depth of a quench-hardened layer in an inner or outer surface of a hollow or solid part can be measured by a non-destructive inspection by monitoring a change in size of the member which occurs as a result of its quench-hardening treatment. The measured change in size is compared with a pre-measured change in size of an adequately quench-hardened member or a value obtained by a comparative calculating operation in accordance with a pre-determined algorithm on the basis of which the measured quantity of change is compared with a pre-determined value of the good member to thereby judge the state of quench-hardening. Thus, even in the case of parts having a complicated shape or even in the case of small sized hollow parts, the quench-hardened depth of a quench-hardened layer and the quality of the quench-hardening pattern of the parts can be measured by a non-destructive inspection. <IMAGE>

Patent GB-2288979-A (GB)
Title: Sterilising compositions
Inventor: CROUD VINCENT BRIAN
IPC: A01N37/16
Filed: 1994-05-06
Abstract: A bleach activator of the type commonly used in laundry detergents is used to activate a peroxygen bleach used to sterilise a prosthesis removed from the body before reinsertion. The prosthesis may be a set of dentures, contact lens or a diaphragm. The bleaching solution is subsequently neutralised with a neutraliser compound which reacts with peroxygen bleaching species. The neutraliser may be an a -ketoacid, preferably pyruvic acid. The compositions may contain an indicator which changes colour upon neutralisation of old bleaching species. The pH of the sterilising solution is preferably in the range 4 up to the pKa of the protonated form of the bleaching species, which is usually a percarboxylic acid. Preferably the pH is in the range 4-7.7. Activation of the peroxygen bleach source allows improved sterilisation to be achieved, whilst neutralisation gives improved comfort to the wearer and is particularly desirable for removal of percarboxylic acid species present in the sterilising solution.

Title: Method of reducing redundancy in a multi-channel data transmission
Inventor: EDLER BERND
IPC: H04N19/593
Filed: 1994-05-26
Abstract: In this method, existing cross correlations between the two audio and/or video signal channels x(n), y(n) are determined taking into account the delay-time differences. In the data transmission, a signal channel will transmit the predictor coefficients ak obtained from cross correlations, delay-time differences d, and the prediction errors e(n), At the receiver 2, the signal y(n) of the second channel is reconstructed from the transmitted signal channel x(n), the predictor coefficients ak, the delay-time difference d and the prediction error e(n) of the signal. In this way, the amount of data to be transmitted in the case of multi-channel video or audio signals is reduced. The data is transmitted via a data line 20 or by electromagnetic waves. Coding and multiplexing follows the adaptive inter-channel prediction, Figs 2, 3, (not shown). <IMAGE>

Title: Reducing quantization noise
Inventor: LUZ YUDA YEHUDA
IPC: H04B7/185
Filed: 1996-02-13
Abstract: In a quantization noise reduction circuit (200), a feedback signal ( W ) is subtracted from an input signal ( X ) to the quantization circuit to reduce quantization noise. The feedback signal is generated as a filtered difference between a sample of a N bit signal ( X ') and a time coincident sample of a M bit quantized signal, where M < N. The feedback signal is subtracted from the input signal ( X ) prior to quantization thereby introducing out of band noise into the input signal for reducing in band noise in the quantized signal ( Y ).

Title: Differential gearing prevents localised contact if gears are slanted
Inventor: ISHIKAWA YASUHIKO
IPC: F16H48/285
Filed: 1996-04-09
Abstract: A differential casing contains a pair of helical side gears as well as a pair of helical pinion gears 41 accommodated in bores formed in the casing. The long and short pinion gears and have first gear portions 45 meshing with the side gears, respectively, and second gear portions 47 meshing with each other. The pinion gears are designed to prevent occurrence of localised contact of the pinion gears with the meshing gears even if the pinion gears are slanted relative to the axes of the bores while transmitting torque. In one embodiment (Fig. 8), each gear tooth of the long pinion gear 41 is so tapered that its tip thickness is gradually decreased from an axial end of one gear portion toward the other gear portion. Even if the long pinion gear is inclined by meshing reactive forces, it is possible to ensure sufficient tooth bearing areas at respective tooth faces of the pinion gears. In another embodiment, each gear tooth is curved conversely from an axial end of one gear portion toward the other gear portion. In a further embodiment, a correction is applied to the tooth trace angle of the pinion gear which is inclined while transmitting torque.

Title: Downhole lubricator
Inventor: MACLEOD ALLAN
IPC: E21B34/00
Filed: 1996-05-29
Abstract: The invention is an assembly of two flapper valves which is run into the wellbore to straddle pre-existing control line connections used normally for actuation of a sleeve for a single subsurface safety valve. The lower flapper is closed through the use of one of the control lines. It is then tested against formation pressure to make sure that it holds. Upon determination that the lower flapper is holding, the upper flapper is shut off using the other control line. By adding additional pressure to the control line for the lower sleeve, further movement of the lower sleeve is obtained to urge another sleeve into contact with the upper flapper to provide support for it so that it can be tested from above. Once the two flappers have been tested, uphole assembly in the wellbore can begin through the wellhead in the zone above the tested valves once assembled. Coiled tubing or wireline can be advanced sealingly through the wellhead as the assembly is lowered past the flappers which are now allowed to open. The flapper assembly is eventually removed.

Title: A brake system with traction control
Inventor: PUESCHEL HELMUT
IPC: B60T8/175
Filed: 1996-09-18
Abstract: Traction control of a brake system of a motor vehicle involves, in a second phase (II, figure 2), with valves 118 and 146 closed, inlet valves 124 and 126 open, and pump 142 operative, pulsing of the outlet valve 132 or 134, associated with a spinning wheel, between its open and closed states while the wheel spin remains within a predetermined range. Initially, in a first phase (I), with the wheel spin being greater than a preset value, valve 118 is closed, valve 146 is opened, and pump 142 is operative (inlet and outlet valves remaining as illustrated). In a third phase (III), when wheel spin drops below the predetermined range, the associated outlet valve is opened, valve 146 is closed, and valve 118 is pulsed to allow pressure fluid to flow back into the master cylinder. It is stated that the outlet valve is pulsed in order during a control phase to keep the achieved pressure level.
