Abstract: A potato peeling machine has a container for receiving potatoes on an abrasive rotary floor. Vanes are attached to the underneath of the floor and are driven unidirectionally by water fed into the container through a permanently-attached hose connectable to a mains water tap. The machine has a lid that is placed on to the container and rotated into a locked position. The direction of rotation of the lid is the same as that of flow of the water within the container, so as to enhance the locking.

Abstract: A D.C. gas discharge display panel for operation in a storage mode with internal memory, comprises a gas filled envelope bounded by a pair of glass plates (2 and 3), which carry on their respective internal surfaces orthogonal arrays of cathode conductors (4) and anode conductors (6) separated by a discharge gap (30). The array of cathode conductors is covered by a layer (10) of resistive material, which in turn is covered by a cermet layer (12). The cermet layer protects the cathode conductors from ion bombardment induced sputtering during discharge. The layers provide a resistance to each discharge cell, and provide isolation between individual cathodes by reducing discharge spreading along the cathode conductors and preventing surface charge build-up during panel operation. By using a combination of metal and insulator in the resistance layer, the D.C. discharge can be sustained at lower operating voltage, permitting a reduction in the power requirements of the panel.

Abstract: A process for modifying the acidity and ion content of an aqueous food product by electrodialysis in a system comprising a pair of electrodes and two or more membranes which are either exclusively cation-permeable or exclusively anion-permeable, wherein a feed stream is separated by a membrane from a waste stream, the latter containing a dilute aqueous acid solution when the membranes are cation-permeable and a dilute aqueous basic solution when the membranes are anion-permeable, to which system the application of an electric field between the electrodes causes migration through the membranes of either protons or hydroxyl ions out of the waste stream into the feed stream and either cations or anions respectively out of the feed stream towards their respective attracting electrodes. The process is valuable for reducing the acidity of instant coffee.

Abstract: A magnitude comparator circuit is provided for determining the largest binary number, out of a plurality of binary numbers received bit-serially, in parallel. A latch is used to store the results of the comparison and is initialized to an all logic 0 state. The latch has a unique one-bit location corresponding to each number being compared, and a logic 0 stored in the latch indicates that the number corresponding thereto is still in contention (i.e remains a candidate) for being the largest, and a logic 1 indicates it has been eliminated from contention. As the numbers are received bit by bit (most significant bits first) the bits are applied to gating circuits, one for each number, which invert the bits and store the inverted result in the latch. The exceptions to this are twofold; a) when a number has already been eliminated from contention, as indicated by a logic 1 stored in the latch corresponding to that number, it remains a logic 1; and b) when the remaining candidates all have a binary 0 in an equal significant bit location no choice is of course possible and the aforestated inversion does not take place and the contents of the latch are simply recycled.

Abstract: A self-aligning fuel nozzle assembly 34 maintains the alignment of a swirler member 30 and a fuel nozzle 18 upon displacement of the combustor liner 24 relative to the combustor housing 12 of a combustion chamber assembly in a turbine engine 10. The selfaligning fuel nozzle assembly 34 mounts the swirler member 30 to the combustor liner 24 by a device having six degrees of freedom including a ball and socket joint 44,50 which is placed within a structure so as to permit movement in the three main Cartesian directions of a rectangular axis system. The combustor liner 24 is installed within the combustor housing 12 in such manner that the fuel nozzle 18 is slidably received within the swirler 30, with the swirler 30 being biased against the fuel nozzle 18 by a helical spring member 96 forming part of the assembly. The assembly 34 is slidably mounted between plates 74, 76 on the liner 24 to allow side to side and up and down relative movement of the liner 24 and housing 12. The self-aligning fuel nozzle assembly 34 reduces the development of local stresses between the swirler 30 and the fuel nozzle so that wearing between these parts is reduced. The swirler member 30 and fuel nozzle are retained in aligned positions so that the self-aligning fuel nozzle assembly 34 promotes improved fuel economy in the engine.

Abstract: When preparing foods cooked in containers or vessels (1, 3) the pressing operation to compensate for the reduction of volume caused by the cooking is automatically achieved in the container upon reaching a predetermined temperature by at last one temperature-operated actuator. The actuator (21, 30) either controls a holding device (20-28) retaining compression springs (15) already present in conventional cooking vessels, or directly exerts the pressing action and in such case locking means (36, 37) is provided to keep the lid (3) pressed against the product (2) after that the compression action of the actuator ceases when the temperatures drops below the intervention threshold. The invention also relates to containers or molds designed to carry out the process.

Abstract: A coupler for coupling together two pipes comprises a substantially cylindrical body (6, 10) on which a plurality of hook arms (30) carrying latches (34) are pivotally mounted. An actuator ring (46) is rotatably mounted on the coupler body (10) and has a cam surface (50, 53) which is arranged to cause the hook arms (30) to pivot to move the latches (34) into and out of a position in which they serve to lock a flange (42) at the end of a pipe (44) to a front flange (6) of the cylindrical body. The pipe flange (42) can be guided onto the coupling by guides (22) and the guides are also effective to hold adaptor plates on the flange (6) so that the coupler can be used to couple pipes of different diametres. No axial movement of any of the components of the coupler takes place during coupling, movement of the actuator ring (46) being purely rotational and movement of the hook arms (30) and latches (34) being purely pivotal.

These buttons have flat ends for engaging the opposite thrust surfaces (43, 45) The buttons protrude from the supporting metal, allowing cooling fluid to be circulated past to cool the thrust surfaces.
