Patent GB-2235804-A (GB)
Title: Matrix display
Inventor: LEE JAE HWAN
IPC: G09F9/37
Filed: 1990-01-15
Abstract: Colour flap apparatus for displaying information comprising a colour flap unit in which a number of colour flaps are pivotally attached to a shaft and are rotatable about the shaft so as to display the desired colour, thereby forming the one element or dot of the matrix display board. A motor supplies the colour flap unit with driving force, and it is connected on the one hand to a colour selection device 5 and on the other hand to a rotary switch 2. The colour selection device consists of multiple switches 51,...52,...5n, with one for each colour flap, and enables a desired colour flap to be represented by opening the switch corresponding to the desired colour. The rotatory switch 2 has the role of opening and closing the contact between the motor and the colour selection device by means of a rotary contact brush 21a and an outer contact pattern 22c, so that the motor is rotated and the desired colour represented.

Title: Thermostatically controlled valve for engine cooling system
Inventor: BREEDEN ANTHONY PHILIP
IPC: G05D23/13
Filed: 1990-02-23
Abstract: A thermostatically controlled valve for an engine cooling system, comprises a housing (1) having a port (7) in a side wall thereof. A sleeve (2) is slidably mounted in said housing and normally engages a sealing ring (3) to close said port (7) from communication with a fluid path (4) defined by the housing (1) and the sleeve (2) and extending between an inlet (5) at one end thereof and an outlet (6) at the other end thereof. An expansible thermostatic element (8) mounted in the fluid path (4) and connected to the housing (1) and sleeve (2) acts to move the sleeve (2) relative to the housing (1) to open communication between the port (7) and the fluid path (4) when the thermostatic element (8) senses a predetermined temperature. Means (2a, 2b, 12) enable fluid from the port (7) to flow around at least a portion of the expansible thermostatic element (8) when communication between the port (7) and the fluid path (4) is closed. <IMAGE>

Title: Tiling tool
Inventor: MURPHY AUSTIN CHARLES
IPC: B28D1/22
Filed: 1990-11-19
Abstract: A tiling gauge comprising a cut edge defining member 1, a tile space defining member 2 and a clampable linkage connecting the first and second members. The linkage includes two linkage members 3, 4 extending between the first and second members and a double acting clamp 10 on the second member for clamping the two linkage members simultaneously.

Patent GB-2248535-A (GB)
Title: Packet encryption in a non-secure data communication system
Inventor: WHITE ANDREW
IPC: H04L29/06
Filed: 1991-07-18
Abstract: Data is encrypted for transmission over a non-secure communications network by providing the data (D) with a header (H) and a trailer (T) portion containing full information as to the sender and recipient of the data so as to form a data packet (a), encoding the packet (HE, DE, TE; (b)), and providing the encoded packet (HE, DE, TE) with a further header (H') and trailer (T') portion to form a further packet (c). The further header and trailer portion only contain information identifying the entry and exit nodes at which the further packet enters and leaves the non-secure network. On arrival at the exit node the further packet can be decoded to reconstruct the original packet (b) which is then conveyed to its destination via a local secure network. Padding non-secure network with dummy messages makes it impossible to identify the presence of genuine traffic between particular nodes of the non-secure network. Thus secure data may be sent via commercial non-secure packet switching networks without indicating its presence.

Title: Screen separator
Inventor: HUNTER STANLEY GORDON
IPC: F04D15/00
Filed: 1991-12-20
Abstract: Metal valves are progressively adsorbed from a metal rich liquid (pulp) which is circulated through a series of tanks containing adsorbent (carbon or resin) particles. Each tank encloses a cylindrical screen 14 enclosing a rotary impeller which pumps the liquid inwards through the screen and out of the tank, while the screen retains the adsorbent within the tank. The screen 14 is closed, in effect, at the bottom by a tubular baffle through which extends a shaft 20 carrying impeller 16, inside the screen, and a further impeller 22 and blades 18, outside the screen. The top of the screen is open, and screened liquid is lifted by impeller 16 and falls into annular channel 34 to be fed to the next tank. Impeller 22 improves contact between liquid and adsorbent, and blades 18 clean the screen. Periodically flow is stopped, and saturated adsorbent is removed for further treatment to recover the metal. <IMAGE>

Title: Inventory management for combination goods.
Inventor: HASHIMOTO YOSHIMITSU
IPC: G06Q50/28
Filed: 1993-03-08
Abstract: An inventory management program including a goods master file storing information on whether each good is for sale as a single item or as combination goods comprising a combination of a plurality of items. When the ordered goods are combination goods, the processing device checks the inventory master file to determine whether or not there is a sufficient number of the element goods in stock for filling the quantity of order. When there is a sufficient number of the goods, the processing device performs stock assignment and updating in which a number of assignment is subtracted from the number of stock of the element goods stored in the inventory master file. When there is not such a sufficient number of the element goods, the processing device performs either a process for purchasing a required number of the element goods or a process for assigning substitute goods. <IMAGE>
