Title: Self-levelling vehicle pneumatic suspension - has manual control lever to alter height for (un)loading
IPC: B60G17/052
Filed: 1974-12-20
Abstract: The vehicle is fitted with pneumatic, self-levelling suspension which automatically sets the height of the vehicle independently of the loading. In order to alter the height of the suspension to the height of a loading ramp, or to slide under a container etc., the driver is provided with a manual control lever which has four settings. These are, drive, up, down and stop. When driving along the road the lever is set to drive for automatic control. When the driver wishes to alter the height the lever is set to stop in order to lock the suspension. From this setting the lever is moved to either up or down settings against a return spring pressure. This gives the driver full control in that he can lock any setting simply by releasing the lever to return to the stop setting.

Title: Confectionery or dessert prod. based on ice-cream - with chewing-gum tablet at base to remove after-taste effects
IPC: A23G4/18
Filed: 1977-04-06
Abstract: Ice-cream prod. for confectionery or dessert, consists of ice-cream and chewing gum, placed in a common container, to remove any after-taste. The external envelope, in the form of an inverted cone, can be made of paper, metallised paper, plastic film or a moulded plastic material. It can also consist of the conventional cornet of the wafer biscuit type with an external protective envelope. A tablet of chewing-gum is placed below the ice-cream and is only accessible when the latter has been consumed; it can then be recovered by the consumer. The chewing gum when placed in the palate, after consuming the ice-cream, acts as a cold source which only takes up heat gradually; this ensures a slow transition from the low temp. produced by the ice-cream back to the normal temp. The chewing-gum also promotes a salivary secretion which rinses the palate and removes the remainder of the ice-cream.
