Patent SE-7909968-L (SE)
Inventor: LARSON E R
IPC: F16B23/00
Filed: 1979-12-04
Abstract: There is disclosed an improved fastener and driver assembly which assures sufficient depth of engagement between the drive socket of the fastener and the working portion of the driver bit to provide efficient torque transfer from the driver to the fastener. The assembly includes a fastener having a recessed drive socket which is multi-lobular in cross-section, having an inner surface formed by alternating and smoothly joined flutes and lobes. The assembly also includes a driver for imparting rotational torque to the fastener which includes a head portion having a tip end and a center axis. The head portion of the driver is correspondingly multi-lobular in cross-section. The flutes are formed generally parallel to the center axis of the driver while the lobes of the head portion are tapered axially, converging toward the tip end of the head portion. This arrangement enables the driver head to enter the fastener socket to a predetermined depth, without binding, to thereby insure sufficient depth of engagement between the fastener lobes and the driver flutes to provide efficient torque transfer from the driver to the fastener.

Abstract: An apparatus and method of automatically threading successive closed framed openings by helicopter towing a line equipped with a separable coupling. The invention utilizes a short cable loop pre-threaded through each closed frame such as the throat of a stringing block which cable loop is provided at its ends with coupling halves releasably supported at the opposite ends of a trough overlying the framed opening to be threaded. A helicopter is manoeuvred to drop the towing line coupling into a trough where its halves are automatically separated and thereafter recoupled to a respective end of the cable loop. Subsequently, the forward coupling can be similarly separated for insertion of a second cable loop in the towing line at the next threading apparatus in the helicopter's path of travel.

Abstract: The invention relates to the shaping of coils in the form of helically wound bare wires, particularly for use in "smooth top" cookers. In so-called "smooth top" cookers an unprotected helically coiled wire is secured in an electrically and thermally insulative base to transmit heat primarily by radiation through a smooth top, normally of glass ceramic. The coils used in such cookers are normally very springy and require careful securement if they are not to free themselves during the life of the cooker. According to the present invention, the stresses which cause this springy resilience can be relieved by holding a coil in a groove of the desired configuration and heating it, normally to the annealing temperature of the material of the coil. The subsequently cooled coil will then hold its shape and not tend to straighten and can be more easily held in place in the cooker.

Abstract: A regulating device is proposed for an internal combustion engine having a throttle device and a controllable bypass channel in the intake tube, where regulation is effected to a minimum volume (Q/n) in overrunning above a predetermined rpm value and to the idling rpm below this rpm value. The purpose of this regulating device is the substantially precise preliminary control of an adjustment member in the bypass channel around the throttle valve to the opening cross section required for idling. The regulating device includes a switchover device (alternating switch), to the input terminals of which the output signals of the regulators for volumetric value and for idling rpm are applied. In the case of temperature-dependent minimum and threshold volumetric values, good warmup performance can be attained.

Date Feb. 2, 1984.A suction device, particularly intended for use as a soft-solder suction device in soldering operations. The suction device includes a housing (1) having a cylindrical chamber (2) and a suction pipe (11) connected to one end of the chamber. Arranged for axial movement in the chamber is piston (4). The piston is arranged to move extremely rapidly through the chamber, from a starting position located adjacent the suction pipe, in response to the release of a force acting automatically upon the piston. This piston movement creates a subpressure, which results in an effective suction effect at the tip of the suction pipe (11). In order to enable the suction device to be held absolutely still when movement of the piston (4) is initiated, the piston is arranged to be operated electromagnetically. The electromagnetic force is initiated by means of a switch which is separate from the suction device and which is foot-operated or arranged to be operated by some other part of the body. In order to simplify cleaning of the suction device, and to extend the intervals at which consecutive cleaning operations need be carried out, the suction pipe (11) is provided with a conically tapering suction channel (12).

Abstract: An ignition circuit according to the present invention has the properties of trigging, i.e. releasing the spark at a predetermined point behind the top of the primary voltage (the ignition generator voltage). During the ascending primary voltage the ignition switch (12) is conducting while a capacitor voltage (UK) is developed. When the primary voltage has passed its top value a potential difference to the capacitor voltage (UK) is created, which is used for the control of the switch to make it break. By the interruption of the primary current an ignition voltage is induced at duty r.p.m. in an ignition coil (11). At an extremely high r.p.m. the ignition is delayed behind the voltage top whereby the induced voltage will be too low for ignition. Too high an r.p.m. is thereby avoided.

The accuracy of setting using these devices does not, however, satisfy the required setting accuracy in many cases. A method is provided, by means of the invention, in which a feeler head is slowly approached towards the surface or edge to be touched until the contact of the rotating feeler head with the surface or edge corresponds to a feeler head rotational angle ( alpha ) which is greater by a predetermined safety value than 180 DEG  but is smaller than 300 DEG . The device for this purpose consists of a housing with an electrical voltage source and circuitry equipment for optical display elements, the housing being penetrated by a hollow shaft connected with one pole of the voltage source. The hollow shaft is provided at its machine side end with an accurately ground receiving region and carries, at its free end, an electrically insulated feeler head which is connected to the input of an amplifier.

Abstract: The press installation includes a screw rotatably mounted in a cylinder. A very high pressure is produced to separate liquids from a mixture, with the separated liquid being drained off through bore holes in stationary pins at the location where it is released. In the discharge zone, the screw is devoid of threads whereby the annular cross sectional area between the screw core and the cylinder is increased. This extends the retention time and thus the amount of dehydration of the material as it passes through the discharge zone. Additionally provided in the discharge zone are annular offsets around the screw core in the vicinity of the pins, which prevent the penetration of solids into the drainage bore holes.

A copper wire is utilized as the wire electrode and has a tensile strength at the elastic limit of between 11 and 13 kg-f/mm2 and has a percentage elongation at break of 26 to 17%. The reels are pressed together by a force of 60 to 70 kg, and the copper wire is subject to a tensile stress of less than 10 kg-f/mm2 while passing over and between the reels. The reels are maintained at an operating temperature of 10 DEG  to 30 DEG   C. as the wire electrode passes thereover, so that a maximum elongation of the wire of 6% when passing over the first reel, and a maximum further elongation of the wire of 6% when passing over the second reel, is attained.

Abstract: In centrifuges that concentrate liquids that contain suspended solids and wherein the concentrated solids are removed from the centrifuge at a constant rate, the concentration of solids leaving the centrifuge must be regulated. Some of the concentrated solids leaving the centrifuge for example can for this purpose be returned to the centrifuge. In the method in accordance with the invention, the solids leaving the centrifuge through its second outlet are diverted through a measuring channel that contains a bob. The shape of the bob ensures that the force exerted on it by the solids will increase with the viscosity of the solids. The force can accordingly be exploited to adjust a flow regulator in such a way that amount of solids returned to the centrifuge is decreased.
