Title: Snack food
Inventor: READ MARTIN PETER
IPC: A23L7/157
Filed: 2001-08-22
Abstract: A snack food is prepared using a combination of potato and baked bread made from wheat flour. The bread used may be yeast or chemically leavened. The potato may be potato granules or flakes or powder or fresh cooked potato. The two principal ingredients may also be mixed with other texturising and flavouring ingredients. The mixtures are formed into a plastic dough by the addition of water or other wetting ingredients and mixed in conventional dough mixers. The dough is formed in depositors or sheeters and cutters into suitable snack food sized pieces of adequate thickness and diameter and then dried, to give a crisp texture and long shelf life, by a number of alternative drying techniques including air drying and frying in vegetable oils. The final snack food may be coated with flavours and seasoning and vegetable oils to create taste and texture appeal.

Title: A half fitting prevention connector having a slidable fitting detection member
Inventor: ENDO TOMOMI
IPC: H01R13/639
Filed: 2002-04-09
Abstract: In a half-fitting prevention connector (31) of the invention, when a pair of connector housings (40, 50) are fitted together, a half-fitted condition of the connector housings (40, 50) is detected by determining whether or not a fitting detection member (60) on first connector housing (40) can be slid into a proper fitting detection position. The proper fitting detection position of the fitting detection member (60) is set at a position which is nearer relative to a front end of the housing than its initial position is. Therefore, by one operation for fitting the two connector housings together, with the fitting detection member held with the hand, the housing-fitting operation and the detection member-moving operation can be completed at a time. And besides, there is no need to change the positions of the fingers during this operation, and the housing-fitting operation can be effected with a reduced number of operations. A full or misfitting position may also be determined by a coloured indicator portion of the housing.

Abstract: A Personal Area Network Security Domain (PSD) 50 is formed between PDA 52, mobile terminal 54, PC 56 and printer 58. The PSD 50 allows the sharing of resources between the devices within the PSD. If the devices within the PSD 50 are located remotely from one another, communication between those devices will be performed via mobile or cellular telephone network 66 and the Internet 68. For each set or association of similarly located devices within the PSD 50, one of those devices will be a gateway device.

IPC: E04D13/03
Filed: 2004-03-05
Abstract: A method of producing a light redirecting structure comprising a three dimensional structure formed from a segment of sheet plastics material having at least one parallel or concentric array of cuts <B>15</B>, <B>16</B>, <B>17</B>, <B>18</B> is disclosed. The cutting is performed with a laser and may form more than one parallel array of cuts <B>15</B>, <B>16</B>, <B>17</B>, <B>18</B>. In a first aspect the cutting is performed before the three dimensional structure is formed. The three dimensional structure is formed by locally heating the segment along desired fold lines 19, <B>20</B>, <B>21</B>, between the arrays of cuts <B>15</B>, <B>16</B>, <B>17</B>, <B>18</B>, and folding the segment along the heat softened lines <B>19</B>, <B>20</B>, <B>21</B>. In a second aspect the forming of the three dimensional structure, by folding or moulding, takes place before the cutting and the cuts are made parallel to the base of the structure. In a third aspect the three dimensional shape is a truncated cone and the cuts are concentric about a point which would form the peak of the cone, in this case the whole segment is heated so that it can be formed into the truncated cone.
