Patent GB-2197517-A (GB)
Title: Coin handling system
Inventor: CROSSMAN THOMAS
IPC: G07F1/04
Filed: 1987-10-29
Abstract: The coin handling system prevents coin to coin contact taking place in coin operated equipment. This is achieved by an arrangement whereby the presence of a coin activates a lever which then prevents a subsequent coin touching the previous one. A series of such levers are employed in the coin store of coin operated equipment, the actual number depending upon the number of coins to be stored. When the first coin is cleared from the store by a suitable gate arrangement, all coins move along the store by one position, the separation being maintained by the interaction of the levers and coins. The advantages of the system are that a wider range of coins from one coin set can be accommodated in a single store than is presently possible. The coin insertion sequence is maintained for the purposes of microprocessor control since a single store is used. Since coins cannot overtake each other the risk of coin jams is lessened.

Title: Drink dispensing
Inventor: SPARKES JOSEPH HENRY
IPC: B67D1/04
Filed: 1987-12-07
Abstract: A drink dispenser (1), particularly for carbonated drinks, comprises a keg (2) with a top inlet aperture (3) sealed by a cap (4) and a lower outlet (5) fitted with a tap (6). The cap supports a flexible sack (11) within the keg (2) which communicates through a tube (8) with a hand pump (7) supported on the cap. When drink (15) is withdrawn from the keg through the outlet, air may be pumped into the sack to expand it so as to maintain the pressure in the keg above atmospheric pressure both to enable further drink to be withdrawn and to ensure that carbon dioxide remains dissolved in the drink during storage and is not released until the drink is withdrawn for consumption. In an alternative dispenser the flexible sack (ii) is replaced by a rigid annular diaphram (Fig. 2). <IMAGE>

This permits the first belt run 26 to freely pass through the second attachment means. In this way movement of one shutter 14, 16 is transmitted to the other shutter without requiring a complicated or bulky connection.

Title: Adjustable holding device for screen printing stencil
Inventor: SCHMID OTTO E
IPC: B41F15/36
Filed: 1990-07-16
Abstract: In a screen printing machine, a holding device (12) for the screen printing stencil comprises two parallel precision rods (18, 19) which are each held rigidly at the front and the rear in a mounting device (26, 33). Two transverse bars (63, 64) are guided on the latter in a displaceable and clampable manner in the form of a frame. The transverse bars bear clamping devices (13, 14, 15, 16), by means of which the stencil is fixed to them. The clamping points of these clamping devices can be adjusted in the X direction and Z direction by means of fine adjustment screw-devices. Consequently, the position of the stencil can be adjusted precisely. As a result of the displaceable transverse bars (63, 64), adaptation to various stencil sizes is possible. Therefore a small stencil can be used for small motifs and a large stencil for large motifs. <IMAGE>

Title: Fumigation method
Inventor: WATSON CHRISTOPHER RUSSELL
IPC: A01M17/00
Filed: 1990-11-27
Abstract: In a method for fumigation of granular or particulate material in the hold of a ship using methyl bromide as fumigant, methyl bromide is fed into the sealed hold of the ship through one of two perforated pipes, a first pipe lying below the cargo and a second perforated pipe above the cargo. Hot methyl bromide vapour, intimately mixed with air, is introduced through one or other of the pipes using a reversible fan and is withdrawn through the other pipe and recirculated. Introduction of methyl bromide is continued until a desired theoretical concentration is achieved. During fumigation methyl bromide concentration at various points within the cargo is sampled and the direction of flow of methyl bromide is changed as necessary in order to achieve a substantially uniform concentration throughout the bulk of the cargo. The methyl bromide concentration is maintained about a minimum level such as to achieve a target concentration time product. After fumigation is complete methyl bromide is removed from the cargo preferably by blowing air into the hold through the pipe lying below the cargo.

Inventor: MCCABE CLIVE
IPC: A23F5/10
Filed: 1991-12-11
Abstract: Green coffee beans are blended in a drum 1, roasted in a pan 2 and cooled in a pan 3. Roasted coffee beans are stored in a first hopper 5 and then delivered to a second hopper 6 for delivery to a grinding device 6. Ground coffee from the grinder 6 is collected in a mobile hopper and dispenser 10 which is moved to a feed chute 11 for delivery to a trough 15 which feeds a packaging station. To avoid clogging, a vibrator (20 Fig. 3) de-piles ground coffee in the hopper (16 Fig, 3). The feed chute 11 is also vibrated in response to a low level of coffee in the trough 15 to ensure free flow of ground coffee to the packaging station, on demand. <IMAGE>
