Abstract: The present invention relates to a method and to means in sawing, preferably in frame sawing. 
     The method according to the invention is characterized in that the movement of the saw blade is compulsory guided along slides in such a way that the rearward part of the saw blade - seen in the moving direction thereof - is given a movement towards the work piece while the forward part of the blade at the same time is given a movement away from the work piece, at which the ratio between the movement of the saw blade towards respectively from the work piece and the total movement of the sawblade during one sawing cycle is within the range 7:100 - 1:100. 
     The means according to the invention is characterized in at least two pair of slides (3, 4), along which the saw blade (2) is guided during its movement in both sawing directions, the angle between the slides is in the range between 172° and 179°.

Abstract: An apparatus is proposed for detecting and measuring with reliable accuracy organic fluid components, comprising first and second fluid sensing elements (28, 29), with both elements including a metal which exhibits variable temperature-dependent electric resistance, depending upon the temperature of the fluideous components to be detected, and with each element bearing a catalyst for promoting oxidation reactions of the organic fluids; the second element (29) is spaced apart from and downstream of the first element and comprises a metal filament which acts as both a heater and a resistance element that varies with the temperature induced in it, wherein variations in electric conductivity of the second element reflect the heat produced by the oxidation of the organic fluids; a pair of voltage control circuits are coupled to each of the sensing elements, serving to controllably heat the elements, and to cause controlled but substantial oxidation of the organic fluids passing thereby; and a measuring circuit producing an alternating output signal, which signal is proportional to the concentration of the organic fluids in the mixture entering the detection apparatus.

Abstract: A method of controlling a computer system for the execution of tasks on behalf of a plurality of system computing entities, to transfer pages of data between bulk storage and main memory to maintain in memory pages of data necessary for current system processing requirements. Pages of data that have not been referenced within a predetermined preceding time period, for example, since the last examination by a core table scan mechanism, are first identified on a system wide basis. Selected pages of data so identified, and referenced by the system since being last written into memory are formed into sets. These sets are then transferred to storage for later retrieval as sets when any one of the pages in the set is required by the system for use in memory. Pages identified as having not been referenced within the predetermined preceding time period, on a system wide basis, and which were never referenced since being last written into memory, are made available for paging to memory individually. A significant reduction in overhead is provided, as compared with prior art paging mechanisms.

Abstract: An analog input signal (Sin) is converted into a digital signal. The digital signal is shifted to the difference frequency region by mixing it (24, 25) with each of a sine wave local signal (26) and a cosine wave local signal (27) to obtain complex waveform data. On the other hand, a trigger signal (T) is generated when a reference signal (Sr) meets a specific requirement, and a frame composed of a fixed number of data is defined which is synchronized with the trigger signal (T). The complex waveform data of each frame thus defined is phase rotated (38) so that its phase angle has a predetermined value, or the phases of the local signals are synchronized with the trigger signal so that the complex waveform data of respective frames have the same phase. Besides, the in-phase complex waveform data of plural frames thus obtained may also be averaged (40), if necessary.

Abstract: The melt viscosity of vinylidene chloride polymers is reduced by introducing a solid solvent such as dimethyl sulfone into the polymer. The sulfone is compatible with vinylidene chloride polymers at a processing temperature above the solid solvent melting point and will reduce the melt viscosity and improve processing of the vinylidene chloride polymer. Upon cooling below the solid solvent melting point, the solid solvent will become microdispersed in the vinylidene chloride polymer with little or no solid solvent remaining dissolved in the vinylidene chloride polymer.

Abstract: This invention relates to glass (1,4) carrying an electroconductive coating (7) and, in particular, to a method of applying bus bars (3,6) on the glass (1,4) to establish electrical contact with the coating (7) and to coated glass (1,4) provided with bus bars (3,6) in accordance with the invention. The method of applying the bus bars (3,6) to the electroconductive coating (7) involves arc spraying molten metal e.g. aluminium on to the coated glass (1,4) in the required configuration which can be defined by either placing a stencil over the surface of the coated glass (1,4) or using adhesive tape (5) to define the required configuration, and then spraying the molten metal. Aluminium has been found to be a most suitable metal for the bus bars and this can be oversprayed with a layer of copper, zinc, tin, a tin alloy, stainless steel, nickel, brass or copper nickel alloy if required. In certain circumstances, for use in architectural applications for e.g. electromagnetic shielding purposes, the bus bars are wrapped around the edge of the glass to provide electrical contact means when the glass is used in a laminate or a double glazing unit.

Abstract: A flywheel device with a torsional damper having a first spring mechanism (40) with a synthetic spring constant K1 and a second spring mechanism (50) with a synthetic spring constant K2, arranged in series with each other as a spring combination. The second spring mechanism (50) is controlled so as to be changed in operation between effective and ineffective states by a second spring mechanism operation controlling device (60). Thus, the vibrational characteristic of the flywheel device includes two characteristics, that is, spring constant K1 and spring constant K3 which is a synthesis of the spring constants K1 and K2. When the rotational speed of the flywheel device passes through the resonance speed of the vibrational characteristic with spring constant K1, the characteristic of the flywheel device is shifted to spring constant K3 and, as a result, there is no notable resonance speed throughout the entire range of rotational speeds. Due to this shift mechanism, it is not necessary to provide a continuously sliding friction mechanism against the flywheel device. Further, due to this omission of the continuously sliding friction mechanism, the torque variation absorbing effect at the standard range of rotational speeds is greatly improved.

Abstract: In an ice storage device for the supply of cold to consumers thereof, in a cylindrical storage vessel (8) are storage tubes (18) which extend rectilinearly from one closing cover (14) of the storage space to the other closing cover (16). Those storage tubes located underneath the longitudinally extending mid-plane of the storage space (forward-flow tubes 20) are connected in the region of the other closing cover (16), outside the storage space (12), to those storage tubes (22) which are arranged above the mid-plane (return-flow tubes 22). A clear distance of 7 to 8 cm is maintained in the storage space (12) between adjacent storage tubes (18), whereas there is a clear distance of at least 6 cm between the storage tubes (18) and fixed walls (10;92). For charging the ice storage device, a refrigerant is evaporated in the storage tubes, so that the ice layers ensuring cold storage occur on the outside of the tubes. The charging state of the ice storage device is determined by the expansion of volume of the water located in the storage space (12) and serving as a cold carrier or by measuring the flow resistance of the storage space. The above-described design and mode of operation of the ice storage device ensure a high storage capacity at a low outlay in terms of construction. <IMAGE>
