Abstract: There is disclosed a beverage dispenser in which a cooled pre-mixed carbonated beverage, or a carbonated beverage component such as soda water, is dispensed through a delivery valve (2b-5b) into a delivery- tube (2c-5c) leading to a spigot (2d-5d) and wherein a carbonating gas is injected via a gas injection line (12a-12d) into the delivery tube immediately downstream of the delivery valve during dispensing of the carbonated beverage. The carbonating gas may be injected continuously during dispensing of the beverage, or an intermittent cyclic injection of gas may be provided. The gas and beverage flow controls may be arranged so that carbonating gas injection is commenced before dispensing of the beverage commences. In an advantageous embodiment, gas may be injected into the delivery tube after the delivery valve is closed, in order to purge any liquid remaining in the dispensing tube.

Abstract: A suction cleaner comprises a primary cleaner (1) and an auxiliary cleaner (2). The primary cleaner 1 includes a fan (11) for sucking in air, and an air channel (6,7,9) disposed upstream of the fan for directing sucked air through the primary cleaner. The auxiliary cleaner (2) includes a dust collection chamber (20) and is attachable to the primary cleaner (1) with the dust collection chamber connected to the air channel (6,7,9) such that, in use, dust within the dust collection chamber is drawn into the air channel for collection.

Abstract: An engine enclosure for a work machine comprises a firewall, left and right-hand side panel structures, and a pivotal hood. Each set of side panel structures is supported by a support tower connected between the frame of the machine and a side margin of the firewall. The support towers are specially shaped to generally conform to the general shape of the panel structures they support. The hood is provided with a hold-open support which maintains the hood in an open position if so desired.

Abstract: A press comprising a frame with an anvil support and a punch carrier, the latter being mounted on the frame so as to be movable between two ends of travel towards and away from the anvil support. A piston and cylinder arrangement is arranged to act on the punch carrier to urge the latter in a direction towards the anvil support. That one of the two ends of travel of the punch carrier which iscloser to the anvil support is defined by a part or parts of the press itself. A limit switch is operable by means of the motion of the punch carrier, or a part connected thereto, in the said direction when the remaining available travel is a distance which is less than the thickness of an operator's finger, to enable the piston and cylinder arrangement to act on the punch carrier with a working force in the said direction up to the end of its travel.
