Abstract: A method and a device for calibrating a pressure air supply system for a pneumatic power wrench (10) including a remotely located pressure air control unit (11), and a pressure air supply conduit (14) connecting the power wrench (10) to the pressure air control unit (11), wherein the pressure air control unit (11) controls the operation of the power wrench (10) by changing in a shifting point (ts) the pressure of the air supplied to the power wrench (10) from one level to another so as to accomplish stop of power wrench operation, wherein a time delay (?t) is caused by the pressure change propagation time through the pressure air conduit. The air conduit related time delay (?t) is calculated in response to the pulse length (t2-t1) of relay controlled successive pressure pulses induced in the pressure air conduit (14), and an advanced pressure change point (tAS) is determined from the calculated time delay (?t).

Abstract: 1479893 Moulding foamed articles having an outer covering layer SAAB-SCANIA AB 13 June 1974 [18 June 1973] 26287/74 Heading B5A In a method of moulding an article by placing a covering sheet in a mould and filling the mould with a foamable plastics material which expands to fill the covering sheet and form a cellular core, the sheet is coated on the side facing the foamable material with a substance which causes acceleration or retardation in the rate of the reaction forming the cellular plastics; this results in the formation of a temporary layer of reduced adhesion in the plastics material whereby the plastics material is able to expand freely in the mould during foaming. In the examples, the foam is polyurethane and the outer covering is PVC treated with (a) a polyurethane varnish containing excess polyol component, (b) an isocyanate or (c) a tertiary amine. Another suggested combination is an epoxy resin forming the cellular core and a covering layer of a thermoplastic/textile laminate treated with a tertiary amine. It is also stated that the outer covering may be a metal or a textile material. A heat softened covering sheet may be plastically deformed by the expansion of the foam. Door panels for vehicles are made.

Abstract: A method for producing a reduced-pressure shaped mould comprises the steps of placing a pattern having gas-permeable orifices on a surface plate and adhering a coating film that is soluble in a solvent to the pattern by suction through the orifices. A flask having evacuating means is then placed on the surface plate on top of the film and the space portion defined by the film and the flask is filled with solid particles containing no caking agent which serves as a mould material. The mould material and flask are covered with an air-tight sheet and the evacuating means of the flask is actuated while that of the surface plate is released so that the sheet and coating film adhere to the upper and low surfaces respectively of the mould material by suction. The pattern and surface plate are then separated from the flask and a solution containing caking agent dissolved in the solvent is applied to the coating film which is adhered to the surface of a cavity formed at the lower surface of the mould material. The caking agent penetrates interstices between the solid particles whereby a layer that has been hardened by the caking agent may be formed in a surface layer portion bounding the cavity.

Abstract: APPARATUS AND METHODS FOR FORMING A PLURALITY OF ELONGATED MEMBERS A plurality of separate, elongated, metallic members, such as wires, are formed simultaneously, e.g., through the application of hydrostatic extrusion techniques, by passing a single metallic workpiece through a die with a plurality of apertures.  The apertures extend longitudinally through the die from an entry wall of the die, and are so arrayed, and the die entry wall includes surfaces which are so configured, as to cooperate to create cross-shear stresses in the material of the workpiece in the vicinity of the apertures.  These cross-shear stresses separate, or assist in separating, the workpiece into a plurality of elongated members, so that the forming process may take place at reduced operating pressures. -i-

Abstract: In a receiver a settable frequency divider (6,7) divides the frequency of a voltage-controlled oscillator (3). The resultant frequency is compared in a phase comparison circuit (8) with a constant reference frequency an error voltage proportional to the phase deviation controls the oscillator (3). The oscillator frequency is furthermore additively mixed with the received frequency in a mixer circuit (2), which is followed by an intermediate frequency amplifier (4). A regulating circuit (5) including a frequency discriminator with a capacitance diode is provided for the purpose of automatic retuning and additional subjective detuning. It generates, in dependence on the deviation of the received frequency from the oscillator frequency as well as also through application of a voltage to the capacitance diode, a regulating voltage which after analog-digital conversion at 11 proportionally varies the set dividing ratio of the frequency divider (6,7). Retuning and search for a different station is facilitated by control keys 13, 14, a coder 15, a switch 12, a D/A converter 16 and a logic circuit 17 which shifts the frequency discriminator characteristics as well as vary the division ratio of 7 until the desired station is obtained. <IMAGE>

Abstract: A plunger having an oblong body with a front end and a rear end and a lancet having a pointed end section projecting axially from said body at the front end is insertable in a cylinder having an oblong hollow body with a front end, a rear end and an axial hole. The plunger of such a length and the lancet is so arranged that the pointed end section of the lancet protrudes a predetermined distance out of the cylinder at the front end when the plunger is inserted thereby defining an operative puncturing position of the medical lancet. The plunger and cylinder have a first engaging stop arranged after partial insertion of the plunger, to temporarily prevent continued insertion at a predetermined initial position. The arresting function of the stop is overcome by applying pressure on the plunger thereby pushing it the remaining distance into the cylinder from the initial position to the operative position.
