Abstract: A transfer trolley, to lift loads but particularly adapted to pick up a patient from a bet using a plurality of horizontally extending tines. Each tine consists of a tube having one end fixed in a position and a free open end. A sleeve surrounds the tube and is withdrawn into the interior of the tubes. The tines are then located next to a patient and a fluid under pressure is inserted into the sleeve, causing the sleeve to emerge from the end of the tube and to insinuate itself under the patient lifting the patient in the process. As the patient is lifted the trolley is moved to place the tube under the patient and to provide support while the patient is moved. The trolley can be adapted to move patients from beds or chairs.

Abstract: An apparatus for transmitting acoustic ultrasonic pulses and for receiving "echos" of the transmitted pulses, comprises a housing, an upstanding wall mounted on the housing defining the mouth of a well, and a transducer mounted in the housing so that the operative part of the transducer is located in the well. The well is substantially watertight and is provided with a jet for introducing water or other fluids to the well, or is pre-filled with fluid.

Abstract: Method and apparatus for rolling dough including rotatable support disc in cooperation with a rotatable obtuse conical roller, means being provided to hold the conical roll spaced above the disc and thereby determine the thickness of the rolled product.

Abstract: An apparatus for use when manufacturing a substantially circular dough product, said apparatus comprising a turntable defining a planar surface, and conical roller means adapted to cooperate with said turntable and defining a rolling line in the region of the roller close to said planar surface, the turntable being rotatable to permit effective movement between said rolling line and the turntable, the apparatus being provided with means to cause the roller and turntable to move from a relative space to part position to an operative position with a reduced spacing therebetween for a predetermined operational period of time and to cause the roller and the turntable subsequently to return to the initial spaced apart position.
