Abstract: ABSTRACT There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of card-iac stimulating pulses.  The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sensitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the read switch overridden, a hysteresis function added and a high rate exceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis.  The pulse generator further includes means for signaling the acceptance of a pro-gramming signal, and means to reset the program acceptance circuit if extran-eous signals are detected as programming signals.  The program signal accept-ance circuit performs several different checks on the detected programming signal including a parity check, an access code check and determining if the proper number of signals were transmitted within a given time.  The timing circuit of the pulse generator includes a crystal clock oscillator and counter means for counting the clock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is determined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreasing with time.

Abstract: TRANSFER MEMBRANE APPARATUS                 ABSTRACT       A dialyser has a membrane assembly (12) comprising two superposed conduits partially defined, and separated, by a transfer membrane wall.  The walls of the conduit are provided with furrowing (38 or 39) extending with a component along the conduits.  Blood is pumped through one conduit by a roller pump (21) and dialysate is pumped in counter current through the other conduit by a roller pump (24).  The conduits communicate with separate chambers in flexible bladders (16) along each side edge of the conduits and the bladders are alternately compressed by rollers (27) to provide a superimposed reciprocatory flow component on the blood and dialysate in a direction transverse to the length of the conduits.  This reciprocatory flow component, in conjunction with the furrows, produces vortexes in, and good mixing of, the blood and dialysate in their respective conduits and hence enhanced contact of each of these liquids with the transfer membrane wall.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are disclosed for pro-ducing self-sustaining, dimensionally stable axially elongated fibrous bodies of suitable cross-sectional size and shape for use as cigarette filters from a bondable continuous filamentary tow of substantially continuous thermoplastic fibers, wherein transport and shaping of the tow during its processing into a bonded fibrous rod are effected pneumatically.  The pneumatic system is designed so as to require the utilization of gas under pressure in sufficiently low amounts to enable eliminating of at least a major portion, and preferably substantially all, of the transport gas in a manner so as not to in-terfere with the bonding operation.  The system further enable variation of the orientation of the con-tinuous fibers within the fibrous rod so that the pressure drop exhibited by the filter elements finally produced may be selectively controlled.  The resulting filter elements, in comparison with the prior art continuous fiber filter elements of comparable press-ure drop characteristics, require substantially less material and exhibit higher filtration efficiency.  The filters, moreover, have a resistance to flow higher in the longitudinal direction than the transverse direction enabling a relatively high ratio of venti-lation air to smoke when used in an air-diluted filtered cigarette.

Abstract: A domestic electrical food processing appliance has a work bowl supported on a base and a detachable cover fixed on said bowl by a bayonet device. An electrical motor is mounted in the base and drives an output shaft which extends within the bowl and carries a cutting tool. The motor is actuated by depressing a push-button slidably mounted in a boss of the base. A safety bolt is pivotably mounted in the boss and urged into a locking position preventing depression of the push-button. The cover carries an arm which, when the cover is moved to its closed position, pivots the safety bolt out of its locking position to allow depression of the push-button. The engagement of the arm with the safety bolt also prevents removal of the cover from the bowl while the push-button is depressed.

Abstract: ABSTRACT              Boiling reactor comprising a reactor core and a pressure vessel enclosing said reactor core and being provided with at least one conduit for discharged steam and at least one conduit for feed water and during normal ope-ration being filled with water up to a certain normal level, the steam pressure in the pressure vessel having a substantially constant value of at least 5 MPa.  The pres-sure vessel is surrounded by a water-filled pool with a water volume above the reactor core which is considerably greater than the water volume within the pressure vessel. The pressure vessel is a concrete vessel having an inter-nal thermal insulation.  The reactor comprises emergency cooling pipes with valves connecting the reactor vessel to the pool. The valves are normally closed.  The pipes are positioned at different levels.  The emergency cooling valves are adpated to be controlled in dependence on the water level in the reactor vessel in such a way that they are opened when the water level is below a certain minimum level.  When the valves are opened, steam is flowing out of the reactor vessel through the upper emergency cooling pipe, whereas water is flowing from the pool into the reactor vessel through the lower emergency cooling pipes as soon as the difference in static pressure in the pool between lower emergency cooling pipe and upper emergency cooling pipe is greater than the pressure drop of the steam flux passing through the latter.  Emergency cooling is achieved entirely without the use of pumps.

Abstract: RCA 74,664 Abstract In a video disc system, the picture display is adversely affected by intermodulation distortion occuring in the signals recovered from the disc record.  A non-linear circuit, responsive to a bias signal, generates a compensation signal in a diode modulator for cancelling the undesired distortion components of the recovered signal. The resulting distortion after cancellation is measured in a comparator circuit to determine if the distortion has increased or decreased.  The comparator circuitry outputs an appropriate signal to bias the non-linear circuit to further reduce the distortion components.  A small oscillation is superimposed on this bias signal, which oscillation simplifies the comparator circuitry and forces the circuit to search for an optimum operating point.

Abstract: ABSTRACT Apparatus for purifying a body of water is described.  Air is drawn in by a water-jet pump and the air rich water is pumped through a conduit, the pump and the conduit lying beneath the surface of the water, as is known.          According to the invention, the conduit is double walled, having an air permeable inner wall and an air impermeable outer wall.  Air bubbles tend to collect on the inner wall, which may be formed as a fine-mesh screen, thus increasing the period of residence of the air in the body of water and enhancing the purifying effect.  The apparatus is carried on a frame comprising an upper tubular frame and a lower tubular frame interconnected by vertical tubes.  The combined frame may be lowered and raised by flooding and venting, respectively, by means of suitable valves.  Longitudinal sections of the frame may be partitioned off from each other, thus permitting frame sections to be controlled independently so as to vary the attitude of the frame.
