Abstract: In one embodiment described in the specification, a surgically implantable reciprocating pump employs a check valve as the piston, which is driven by a permanent magnet linear electric motor to assist either side of the natural heart. The pump is implanted in the aorta or pulmonary artery using vascular attachment cuffs such as flexible cuffs for suturing at each end with the pump output directly in line with the artery. The pump is powered by surgically implanted rechargeable batteries. In another embodiment, pairs of pumps are provided to replace or assist the natural heart or to provide temporary blood flow throughout the body, for example, during operations to correct problems with the natural heart.

Abstract: A photo-acoustic gas sensor for measuring a gas concentration, e.g., of an explosive gas, consists of a cylindrical sensor body (1) which includes a cylindrical measurement chamber (13) whose longitudinal axis extends perpendicular to the longitudinal axis of the cylindrical sensor body. Without changing the outer dimensions of the sensor body, the length of the measurement chamber can be changed in accordance with a desired measurement sensitivity and a desired measurement range. A light source (5) is disposed such that it irradiates the measurement chamber without irradiating a gas-permeable membrane (2), so that the membrane will not produce an interference signal. The gas sensor is rendered explosion-proof as the light source and a photo-diode (6) which monitors the light source are tightly sealed from the environment. Proper functioning of a microphone (4), the light source and the photo-diode are monitored by analyzing a background signal.

Abstract: A roller, for use in a photographic sheet material processing apparatus, comprises a core (32) provided with a covering of relatively soft material (34). The roller has a length (L) of from 0.4 to 2.0 m. The core has a maximum diameter (D) of less than 0.04*L m. The roller is characterised by having a deflection as measured by a specific test and a weight (W) below levels defined by a specified boundary condition formulae (1) & (2). Rollers satisfying this condition are characterised in that the core is formed of a composite material comprising fibers and a resin matrix. Such rollers have a relatively small diameter, are light and yet still have sufficient stiffness to avoid substantial wrinkling of the sheet material in the apparatus and to satisfy the requirements of high processing quality.

Abstract: In digital communications over a limited-bandwidth channel such as a radio-broadcast channel, multiple phase-amplitude shift keyed (MPASK) modulation is preferred using close packed hexagonal code. In quantizing such signals, a representation of an equalized received signal is transformed such that, to each symbol of the constellation, there corresponds a respective point on a square grid. A symbol of the constellation is determined as a quantized representative of the received signal by its selection as the one or the other of two symbols of the constellation having transformed representations at vertices of the square or rectangle in which the transformed signal lies. Such quantizing can be performed at a rate which is independent of the size of the constellation, and can be combined with similarly advantageous decoding in a receiver.

Abstract: In the ink jet head described in the specification, a reservoir body contains three ink reservoirs and a vacuum reservoir and a cover plate at the front of the reservoir body provides passages to supply ink from the ink reservoirs to an ink jet array from which ink is selectively ejected in response to electrical signals. Air-permeable, ink-impermeable membranes in a lung plate adjacent to the cover plate provide one wall of the ink passages, and the opposite sides of the membranes communicate with the vacuum reservoir. The reservoir body is made of a heat-conductive material and is removably received in an insulating housing containing a cartridge heater which supplies heat to the bottom of the reservoir body.

Abstract: A description is given of a rotary drum, as for example a rotary kiln, which is suspended within a live-ring by means of axially extending brackets which are retained by the live-ring and bearing, at their free ends, against retaining elements fixed to the rotary drum, in such a way that the vertical load of the drum relative to the drum shell is transmitted tangentially to the live-ring. The brackets are evenly distributed over the circumference of the live-ring fixed to its side faces. Hereby, the live-ring can be made with a smooth cylindrical inner face without teeth, which, besides being advantageous from an economic perspective, also makes it possible to use existing live-rings of the migrating type. Further, all parts of the device will be more readily accessible in connection with inspection and maintenance work in that none of the parts are concealed under the live-ring.
