Abstract: A portable hammer machine comprises a cylinder (11) in which a reciprocating drive piston (40) via a gas cushion in a working chamber (44) repeatedly drives a hammer piston (15) to impact on and to return from a tool (20) carried by the machine as soon as a feeding force is applied via the machine housing (10) to the tool (20) under compression of spring means (23) interposed therebetween. The cylinder (11) is on the one hand provided with primary ports (45) for the passage of gas to and from the working chamber (44), which ports (45) at impacting are opened above the hammer piston (15) to ventilate the working chamber (44), and on the other hand with secondary ports (46) for ventilating the volume (47) below the hammer piston (15) during its reciprocation and impacting. The spring means (23) are pre-compressed in the machine housing (10) so as to balance the weight of the hammer machine when the latter is kept standing on the tool (20) with the hammer piston (15) resting against the tool (20). In such position the primary ports (45) are disposed above the hammer piston (15), and their total ventilating area and distance above the hammer piston (15) are chosen such as to maintain the hammer piston (15) idle irrespective of the operating frequency of the drive piston (40), while bringing the hammer piston (15) into repetitive impacting work in phase with a selected drive piston frequency in response to an application of a feeding force on the hammer machine and a resultant displacement of the hammer piston (15) from the idle position thereof towards the primary ports (45).

By means of at least one heating device (20, 30) the plastic material is heated to an elevated temperature at which the material crystallizes thermally. The supply of energy is discontinued once the material crystallizes at a speed entailing that the thus released effect corresponds to or exceeds that effect which departs from the material undergoing crystallization. The apparatus includes a mandrel (26) having a forming surface (24) which at an increased temperature is brought into abutment against a defining surface (18) of the bottom potion. The forming surface has a curvature which deviates from the curvature of the defining surface (18) so that during the initial phase of the abutment the forming surface is abutting against the defining surface only in a central area thereof. On continued displacement of material in the bottom portion in order to form the portion the size of the central area thermoplastic material intended for temperature-conditioning abuts against the forming surfaces.

Abstract: A magazine for storage of nuclear fuel assemblies with spent fuel in the intermediate storages. In a magazine with a tubular casing (2), intersecting plate (6, 7) form a number of channels (8) for one assembly each. At their end portions the plates (6, 7) are fixedly joined to each other. Their central portions are formed with slits, causing the walls of the formed channels (8) to be resilient perpendicular to the plane of the walls. This limits the friction resistance between a fuel assembly and a channel wall when inserting an assembly with such deformations that it will make contact with a channel wall. Compared with prior art magazines, the channel cross-section may be reduced and greater packing density be obtained.

Date Feb. 19, 1998A pacemaker has control circuits contained in an enclosure and a lead containing an electrical conductor connected to an electrode for delivering electrical stimulation pulses to a heart. The stretching of a wall in the ventricle, corresponding to adequate filling of the ventricle in the heart, is determined in order to identify a time of emitting the stimulation pulses. This stretching is measured indirectly by measurement of pressure in the ventricle using a pressure sensor disposed near the lead in the ventricle. The signal from the sensor is supplied via the lead to circuitry in the enclosure, wherein the signal is amplified and is supplied to an edge detector, which detects an increasing or positive edge of the signal. The edge detector compares the incoming signal with a threshold value, and when the pressure indicated by the signal increases so as to exceed the threshold value, the edge detector supplies a signal to the control circuit which, in turn, triggers the emission of a stimulation pulse from a pulse generator, with or without a delay. The aforementioned stretching can also be measured using a strain gauge or a distance sensor attached to the ventricle wall.

Abstract: A process and device for determining mechanical properties of a respiratory system of a patient connected to a respirator, wherein a short-term occlusion of the patient's airways is performed during an inspiration phase and/or an expiration phase. Initiating of the occlusion is at different points in time within the breathing cycle and during a plurality of breaths. The respiratory flow and the inhaled or exhaled volume of the patient is determined at the beginning of this occlusion. The airway pressure is also measured during this occlusion. The change occurring over time in the airway pressure during a measurement time falling within the occlusion time is determined. Also determined is the course over time of the change occurring over time of the muscle pressure of the patient from the measured values. The course over time of the muscle pressure is calculated by integrating this course over time.

Abstract: At a point on the path of a first voltage signal used to warn of a metal object towards the unit used to signal the warning, this first signal is detected and a second voltage signal with an opposite character to the first signal is sent to a point along the first signal path upstream from the point where the first signal is detected. A summation is made at this upstream point between the first and second signals and the resulting 0-signal is sent via the first signal detection point to the warning unit.  Metal objects passing through a measuring coil (8) cause a change in magnetic field, resulting in a corresponding detection voltage signal being generated to alert the presence of the object. Low frequency signals caused by disturbance are ignored and only those signals with frequencies typical for metal objects are analysed. An Independent claim is also included for the detection device.

Abstract: In a receiving device, a mixer combines a frequency which is different from a carrier frequency by (2n+½)omega0 and a reception signal, provided that n is an integer, omega0=2PI/T, and T is a transmission rate of a base band signal, a filter takes out a base band signal of a center frequency of (2n+½)omega0 and removes a DC component, so as to sample the signal and put it through A/D conversion, a multiplier combines the signal and a polarity signal, so as to obtain an in-phase component p(nT) of the reception signal at time nT and an orthogonal component q[(n+½)T] of the reception signal at time (n+½)T. A branch metric is calculated and maximum likelihood sequence estimation is executed on the basis of those components and a replica signals pR(nT) and qR[(n+½)T], so as to estimate a signal sequence. Thus the receiving device exhibits improved performance as it is capable of eliminating any phase difference and amplitude difference between Ich and Qch and any DC offset, without requiring any large-scale additional circuit.
