Patent GB-2459019-A (GB)
Title: A validation-based http caching portlet markup and refresh method for server-side portlets embedded in a web 2.0 portal environment.
Inventor: BEHL STEFAN
IPC: G06F17/30
Filed: 2009-03-27
Abstract: Disclosed is a method for caching portlet markup in HTTP caches and is for server-side portlets on a portal with a client-side aggregation component in place. The invalidation method is based on cache tokens which are calculated by the server-side portal. When the portal receives an action request for a particular portlet, the portal will execute a dependency filter chain to detect the set of portlets that are affected. For each of these portlets a new cache token is calculated and transferred back to the client using special response headers. The client-side aggregation tracks the cache tokens for all portlets by storing them in a client-side token store. The cache tokens are used to validate received responses, the client-side aggregation compares the cache token from the response with the token from the client-side token store to check whether the response represents a stale cache entry. In the latter case, the client-side aggregation discards the response and sends a conditional HTTP HET request to the origin portal server to get the current markup of the respective portlet. On its way to the client, the stale cache entries are replaced with the fresh response returned by the origin portal server.

Title: Utilization-based fuel cell monitoring and control
Inventor: EDLUND DAVID J
IPC: H01M8/04
Filed: 2009-04-22
Abstract: Fuel cell systems and methods for controlling the operation of components of the fuel cell system, which may include a fuel source and a fuel cell stack. In some examples, a fuel source is adapted to provide supply fuel to a fuel cell stack at a supply pressure. The fuel cell stack produces electric current at a production amperage. In some examples, a control system is adapted to control operation of the fuel cell stack based on a pressure detected at the fuel cell stack. In some examples, a target production amperage is determined based on the detected pressure, such that when electric current is produced at the target production amperage for the detected pressure, the fuel cell stack consumes a predetermined proportion of the supply fuel.

Abstract: 765,103. Distributing music &c. COMMUNICATIONS PATENTS, Ltd. July 1, 1955 [April 6, 1954], No. 10009/54. Class 40 (4). In order to operate a relay 11 at each of a large number of subscribers' equipments of a wired broadcasting system, each such equipment is provided with a capacitor 13 which may be charged slowly through an individual resistance 14 by the connection of D.C. to the cable 2, 3 (through the operation of switch 4 at the transmitting station 1 by an operator) until the voltage across the capacitor 13 is sufficient to cause a discharge tube 12 to fire, whereupon the charge passes through the tube 12 and the winding of relay 11. The relay 11 is operated and brings its moving contacts 10, 19 to their right-hand positions, thus disconnecting the television receiver 9 from the cable 7 and lighting indicator lamp 20. This state of affairs persists until D.C. of opposite polarity is connected to the cable by an appropriate operation of switch 4. The disconnecting action of relay 11 may be over-ruled by the bridging by the subscriber of contacts 17 by the insertion of a coin or check 18.

Title: Improvements in or relating to the trueing and dressing of grinding wheels in grinding machines
IPC: B24B53/07
Filed: 1920-04-14
Abstract: 161,073. Conners, E. R. April 14, 1920. Trueing rotating tools. - A grinding-machine comprises a grinding-wheel 28, Fig. 1, mounted in bearings on a slide 66 adjustable crosswise on a carriage 23, which is traversed on slides 21, 22 by means of a screw 29 engaging a nut 30 on the carriage. The screw is rotated by a shaft 33, through the engagement of a clutch 36 thereon with either a clutch 37 or 38. Reversal of the carriage is caused by a lug 45 thereon engaging a tappet 46 or 47 on a bar 48, which selectively operates the clutches; these can also be operated by hand. The work 16 is mounted between a headstock 12 and a tailstock 14, and is driven from a pulley 19. Alternatively, the work, instead of the grinding-wheel, can be mounted on a reciprocating carriage. A trueing- device comprises an abrading part 75, Figs. 1 and 6, clamped between washers on a spindle 76, which runs in a split bush 78 fitted in a conical sleeve 77. A nut 82 on the bush takes up wear therein. The spindle 76 is driven from the armature shaft 98 of an electric motor through a dog clutch 104, which prevents axial vibration from being transmitted to the spindle 76. A bearing- ring 85, surrounding the sleeve 77, is provided with a stem 87, Fig. 1, secured by a set-screw 90 to a fitting on the tailstock. Alternatively, the abrading part is a hollow pencil 201, Fig. 10, a frusto-conical end of which contacts with the grinding-wheel 28. The pencil is held in a chuck 208 mounted on a spindle, which is carried by radial and end-thrust ball bearings in a barrel 206 and is connected to the armature shaft of an electric motor by a telescopic joint. The traverse of the grinding-wheel carriage or, alternatively, the work carriage causes the grinding- wheel to contact selectively with the work and with the trueing-device.

Abstract: 1528403 Decalcomania BEN CAPPER Ltd 28 April 1977 [18 March 1976] 10842/76 Heading B6C A decal comprises a support 1, a design 2, and a lacquer film 4 incorporating a release agent, there being provided a layer 3 between the design and the lacquer. This layer 3 is provided to ensure that the lacquer can be clearly stripped from the design after the design has been applied, e.g. to ceramic articles since the ceramic pigments normally used in the design tend to give it a matt surface and hence make stripping difficult. If the design 2 and layer 3 are to be glazed over, layer 3 should be hydrophilic to achieve better glaze adhesion. However, in a water-release design, water-insoluble layers 3 are required. These conflicting requirements may be met either by making layer 3 of a waterinsoluble material which can be treated after stripping of lacquer layer 4 to render it hydrophilic, or by using a water-insoluble layer between the design 2 and substrate 1 effective to hold the transferred assembly together, the layer 3 then being a hydrophilic material (Fig. 2, not shown). The decal may be waterreleased or dry-strippable with or without heat.

Abstract: 1466784 Counterpressure filling head CONTINENTAL CAN CO Inc 11 March 1974 [12 March 1973] 10845/74 Heading B8T A counterpressure filling head 10, for carbonated liquids, comprises a valve housing member 14, slidably telescoped within an upper housing member 12, and which is lowered by a box cam 16 to seal the container (C) (Fig. 1, not shown), on a sealing bell assembly 20, and a counterpressure valve 61, opened by cam 97 to supply pressure from a counterpressure line 60, via passageways 63-65 to the valve assembly 30 and into the container (C). As the pressure in the container (C) builds up, back pressure on the piston 48 raises the spring loaded valve 30 and opens the product line 36 and valve 33 for flow of the liquid product, via a product distributor 27, into guide cone 23 and container (C). When the liquid level in the container (C) reaches the lower end of a probe 45, the probe 45 activates an electric circuit to open valve 80 and admit compressed air, from the air line 75, to the space above the piston 48 and so close the valve 30 and shut off the product line 36. The supply line 36 has a member 125 which creates turbulence and a pressure drop in the liquid product to minimize foaming. In the embodiment of Fig. 13, the filling head 10 has a control pressure manifold 158 connected by a conductor 161 to a solenoid 156 which actuates the valve 155. Pressurized air enters the space above piston 134, forcing it downward. The probe 131 is fastened to a collar 132 which moves upwardly and downwardly with the piston 134. A counterpressure channel 151 is filled with gas at counterpressure to apply pressure to the counterbalance ring 149 and so reduce the downward force, applied to the container (C), necessary for an effective seal. The probe may be in two parts, Fig. 14 (not shown) with the thinner lower part extending downwards, for greater penetration of the container, such as in bottle filling. In both Figs. 13, 14, an electrical circuit is closed by means of the liquid level contacting the probe 131, and so actuate the solenoid 156 to open the control pressure valve 155, and allow compressed air to depress the piston 134. This closes the product valve and breaks the circuit.

Title: Generating a pseudo-random sequence of eta-bit words
IPC: H04L9/22
Filed: 1975-03-17
Abstract: 1504806 Pseudo random pulse sequence generators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 March 1975 [20 March 1974] 10941/75 Heading G4D The invention concerns an arrangement for generating pseudo random sequences of the kind supplied by feedback shift registers but supplying n-bit words in parallel instead of individual bits in series. The main register R1, which has no shifting function, has m + n stages. At each clock pulse the last n stages are read to provide an n-bit output word to a register R2. The same n-bit word addresses a read only memory M which delivers a corresponding m + n bit word to a register ADDR1. The other m stages of the main register R1 are read into the last m stages of another register ADDR2 (i.e. shifted six steps to the right) and the contents of ADDR1 and ADDR2 are added modulo-2 and replace the contents of the main register R1 whereupon the cycle is repeated. The result is that at each clock pulse the register R 1 delivers simultaneously the n bits which would have occurred consectuvely from an m stage feedback shift register of the conventional type and then immediately changes to a state n steps later in the usual sequence. The arrangement operates much faster and delivers complete words needed for ciphering in a transmission system.
