Abstract: A piston (16) and rod (18) slide in a double acting cylinder with closed end (12) from which extends a bar (60) having a T-shaped cross-section with a cross piece (64) and stiffening web (66), the edges of which are rounded to engage and slide on the wall of a bore (22) in the piston rod (18), thus supporting the bar in a rigid manner. The face (68) of the cross piece (64) supports a potentiometer track which co-operates with a wiper (118) carried by an insulating carrier (110) fitted into the bore (22). The T-shaped bar (60) partitions the bore (22) into three chambers (65, 67, 69) which are in communication at the distal end of the bar. The carrier (110) is shaped to close the chamber (65) containing the wiper so that there is no fluid flow past the wiper as the piston (16) moves.

Abstract: Four à micro-ondes possèdant un circuit de commande à microprocesseur (18). Le nombre de touches servant à l'introduction des informations relatives au type d'aliment à réchauffer est inférieur à celui d'un four à micro-ondes conventionnel, permettant ainsi à la capacité de la mémoire morte (ROM) du micro-ordinateur de la présente invention d'être inférieure à celle d'un four à micro-ondes conventionnel.

Abstract: The package to be wrapped is moved during a first step towards a foil section which is extended under tension transversely relative to the direction of movement of the package. During a further course of movement of the package the aforementioned foil section is applied to three sides around the package in a substantially U-shape. Subsequently, a loop is formed from the web-like foil by entraining means which act on the web-like foil. The two runs of the loop are releasably held at their ends by related holding means. These two loop runs of the foil are separated from each other using a cutting knife. The foil section thus produced, which runs along the rear side of the package, has a length which is greater than the height of the package. An end section of this foil section of greater length and which protrudes past the package is now displaced towards and against the underside of the package. A wrapping material preferably consisting of a polyvinylidene chloride foil having self-adhesive properties is used as the web-like foil.

Abstract: This invention relates to a process for producing polyisobutene which has at least 70% of its unsaturation in the terminal position. The process uses a complex of boron trifluoride and alcohol as catalyst and a contact time of at least 8 minutes. The feature of the process is its ability to use longer contact times than used hitherto thereby facilitating its commercial operation and improving the control of such an operation. The high terminal unsaturation improves the reactivity of the polymer.

Abstract: The present invention is concerned with a method of molding metallic powders, in which a binder fluid having a specific freezing point, typically water, is added to the metallic powder to be molded to form a mixture, after which a die having the desired cavity is filled with said mixture. The mixture is then pressure molded and rapidly cooled, freezing the binder fluid to produce a frozen molded shape, which is then dried to remove the binder fluid and sintered. The amount of the binder fluid of specific freezing point to be added to the said metallic powder is the minimum amount that will satisfy the dual demands of flowability during molding and shape retention after the removal of the binder fluid, with from 25 to 50 vol% generally being appropriate. Molding is achieved by injection molding, compression molding or other technique in which pressure is applied to the material in the mold. The present invention makes possible the easy and economical mass production of sintered products of complex shape, high dimensional accuracy, and high density using metallic material.

The second inverted output signal has gate propagation times performing intermediate memory functions in place of the feedback loops and includes a synchronizing device connected between the static and the dynamic memory cells. Means are provided for setting the circuit of the static memory cell in operation at relatively high clock frequencies. Thereby the useful frequency range of the multivibrator is at least doubled.

Abstract: A heat exchange structure is constructed from refractory blocks having three linearly aligned flue-forming openings extending from top to bottom of the block. The central opening is surrounded on four sides by refractory and the two end openings are surrounded on three sides. These refractory shapes are assembled in an open basketweave structure to form the heat exchanger. The resulting structure contains vertically extending, interconnected flues of two types, (1) flues of a first type interconnected at alternate layers in the structure to each of the four contiguously adjacent flues and (2) flues of a second type connected to opposed pairs of contiguously adjacent flues at alternate levels and to the other pair of contiguously adjacent flues at the intermediate levels. The net result is a stable heat exchange structure with relatively thin walls, relatively large flues, and means for creating turbulence in gas passing through the exchanger, thus increasing the rate of heat exchange.

Abstract: A stream of high-speed bipolar signals (18) (19) transmitted along standard twisted pair (13) telephone wiring are detected by a circuit (10) that includes a pair of differential amplifiers (20) (21) each having a signal input (11) (12) connected directly to one conductor (14) (15) of the twisted pair (13) and a reference input (22) (23) connected through a peak voltage detector (29) to the opposite conductor (14) (15). The amplifiers (20) (21) function as an input signal comparator which generates a corresponding bit stream of logical ones in response to the bipolar signals that exceed 50% of the average peak voltage input. A threshold bias voltage corresponding to positive going signals on each conductor (14) (15) is generated by the detector (29) and charges separate capacitors (37) (39) that connect each reference input (22) (23) to its conductor (14) (15). The bias voltage and bipolar signals input to each amplifier (20) (21) are algebraically summed which doubles the differential input signal and results in an increased signal to noise ratio of about six decibels.
