Abstract: A container for holding contents as two separate components which can be mixed together later. The container comprises a cup positioned in a neck of the container for receiving a first of the components; a screwcap coordinated with the neck of the container and having a collar extending into the cup, a front edge of said collar forming a strike edge for separating the cup in the region of a line of intended breakage upon a further screwing on of the screwcap beyond a basic position for storage; and a wall of the cup has an annular step, and the strike edge of the collar comes flush on the annular step on the wall of the cup, the step--forming the place of intended breakage--being located at a distance above the bottom of the cup, there being a bead extending towards an outer surface of the collar and projecting inwardly from the inner surface of the wall of the cup, the step lying below said bead; and a clip shoulder is disposed on the collar and engages the bead of the cup wall.

Abstract: A household slicing machine wherein a disc shaped rotary knife is mounted in a vertical plane and a guard, which is separable from the housing of the machine, is movable in a second plane that is parallel to the vertical plane of the knife between a first position in which the guard cooperates with an adjustable abutment to conceal the knife, a second position in which the knife is exposed and the machine is ready for use, and a third position in which the guard can be detached from the housing. A spring-biased locking element is reciprocably mounted in the front wall of the housing to extend into an opening of the guard when the latter assumes its second position and to extend in front of an end face of the guard when the latter assumes its first position. This prevents accidental shifting of the guard from the selected position because each such shifting must be preceded by manual depression of the locking element.

Abstract: A pump/nozzle unit having an injection nozzle installed at at least approximately right angles to the longitudinal axis (A) on the pump housing of the piston injeciton pump. The injection pump is supported with a support face, which embodies its most extreme axial extension, on a support bearing located on the cylinder head of the engine. The support face is embodied by an outwardly pointing end face of a counterpart piston which is inserted into the pump cylinder in an extension of the longitudinal axis (A) and, with an inner end face, seals off the pump work chamber in a pressure-tight manner. As a result, the pumping forces resulting from the fuel which is placed under pressure in the pump work chamber are kept from affecting the pump housing and intercepted at a location on the cylinder head which is remote from a receiving bore for the injection nozzle.

Abstract: To provide a dynamo electric machine, for combination, preferably, with a centrifugal circulating pump, having a rotor which is at least part-spherical, the stator is formed of edge-wound strip material, in which the stator part is a continuous strip of L-shape deformed strip, with notches (9') cut into the L prior to deformation, the bending edge (15) of the L changing throughout the length of the strip, uniformly, with uniform change of the spacing of the notches so that, as the strip is wound over a part-spherical form which defines an air gap between the rotor and stator, the width of the teeth between adjacent notches (9') will increase to define continuous through-slots (9) for the windings, and the bending corner (15) likewise will change from a position near the root of the notches (9') to a position within the solid portion of the second leg (18) of the L.

Abstract: To reduce the number of connecting lines to the triggering circuit, the number of current lead-in terminals (20, 21) multiplied by the number of lead-off or return terminals (22, 23) from the firing circuits corresponds at least to the number of trigger restraint circuits (14-17) which are provided; and each of the trigger circuits (14-17) is connected to a different combination of current lead-in terminals (20, 21) and current lead-off terminals (22, 23), for example: 14: 21, 22; 15: 21, 23; 16: 20, 22; 17: 20, 23. The firing circuits can be tested by a simple test unit (FIG. 2) in which, sequentially, different connection patterns to the current lead-in and lead-off terminals are provided, and current flow checked under standard test voltage conditions.

Abstract: A valve assembly for controlling fluid flow between a fluid source and a load has an intake valve having a valve body displaceable between a closed position preventing flow through the intake valve and an open position permitting such flow and an output valve having a valve body displaceable between a closed position preventing flow through the output valve and an open position permitting such flow. Conduits or passages connect the valves in series between the load and the source so that fluid can only flow between the load and source when both of the valves are in their open positions. Respective biasing units urge each of the valves into one of its positions and respective electromagnet-type actuators are electrically energizable to move each valve into the other of its positions. The one position of one of the valves is the closed position and the one position of the other valve is the open position. In addition the two valves are substantially identical.

Abstract: A spark plug which has a capacitor located therein, connected in parallel to the main or ignition spark gap (13), additional includes a pilot or pre-spark gap (12) located within the insulator (18) of the spark gap, to control discharge of the capacitor (14) through the main spark gap (13). In accordance with the invention, the pre-spark gap (12) is located within a chamber (34) in the insulator which is filled with a pressurized gas, preferably nitrogen under pressure of between 2 to 100 bar, preferably 5 to 30 bar, with the electrodes (27, 27) defining the pre-spark gap being spaced, preferably, between about 0.1 to 1 mm from each other. Placing the pre-spark gap electrodes within a pressurized gas chamber increases the energy available at the main spark gap (13) for ignition even of very lean fuel-air mixtures.

Abstract: Digitalized luminance and color difference signals, the former sampled at twice the sampling frequency of the latter, are interleaved into two data streams (k, m) in each of which a sample of the luminance signal separates samples of different color television signals, one of these streams then being delayed by one period, so the two data streams will simultaneously present successive samples of the same signal component (luminance or color difference). A system of transfer switches and two pairs of 1-kilobyte (one line) stores then makes possible the sequencing, at twice the sampling rate of the luminance component, of all the luminance signal bytes of a television line followed by all of the bytes for that line of one color difference component and finally all of the bytes for that line of the other color television component, with the desired ratio of component segment length in each line, as a time-multiplex color television signal.

The stop is shiftable at right angles to the first plane to change the thickness of the slices and the adjusting device which shifts the stop relative to the knife has a pair of coaxial sleeves rotatably mounted on the stop and defining a helical path having several sections with different leads. A stationary carrier is provided on a working platform in front of the support and has a follower which extends into the helical path.

Abstract: In an electromagnetically operated driving tool, in which a cup-shaped plunger carrying a driver blade is axially slidable in a solenoid, an air damper, combined with a check valve, is provided to damp the plunger during its backward movement to an inoperative position. A hollow cylinder positioned in the plunger is vented through an opening in a housing of the tool and has an interior which is closed at its end with a liftable valve flap. A throttle gap is formed between the plunger and the cylinder, which is adjustable by a piston movable in the cylinder which is made of elastic plastics and is elastically expandable to vary the throttle gap.

Abstract: In a fuel injection pump for internal combustion engines, a leakage connection is provided for varying the fuel supply quantity and the supply onset in accordance with rpm. The leakage connection, in a pump piston executing the stroke movement, is effective only at the beginning of the supply stroke of the pump piston and becomes gradually less effective in stages in the middle rpm range. The leakage connection has an outer groove in the pump piston, a blind bore discharging in the piston end face, and at least one throttle bore connecting the blind bore with the bore bottom of the outer groove. The outer groove extends over only a portion of the circumference of the pump piston and parallel to the piston end face at a very small distance therefrom.

Abstract: A method for manufacturing commutator segmental rings, in which ring-shaped blanks (1) are transformed into commutator segmental rings. The method is carried out with a forming apparatus which uses a ring-shaped die (21) and a rib-forming die (25) to transform the blank (1) into a commutator segmental ring (2) with a flange (4) on its end and a shaft portion (3) with commutator segments (5) and cross pieces (7) connecting them. During the forming process, the die (25) moves against the force of an adjustable elastic counter-pressure apparatus (16; 13, 17, 19; 28). The counter-pressure on the facing side (24) of the upper punch (22), on which the die (25) fits, minimizes formation of a burr on the workpiece, and it permits use of a fastening means of reduced clamping power, thereby according the die (25) a greater pressure stability.

Abstract: To control the pressure p of an operating fluid in an automatic transmission (12), the input speed and output speed (n.sub.T, n.sub.out) of the transmission is sensed, and the pressure (p) is so controlled by a control unit (21) that the transmission ratio which is actually coupled by the transmission, in view of the pressure set by the friction bands, is carried out in accordance with a predetermined timing function (i.sub.com), for example as stored in a read-only memory (ROM, 24). Change in shifting characteristics can be obtained, for example, by operator-selected different time-engagement relationships to obtain maximum passenger comfort or maximum acceleration, or intermediate relationships.

Abstract: A fuel injection pump for self-igniting internal combustion engines includes a displaceable control slide which is operative for blocking a relief conduit provided in the pump for controlling an outflow of a partial quantity of fuel in the pump for affecting the injection time. The control slide is arbitrarily displaceable by a rocker lever which is actuated by a driver by an adjusting lever positioned outside the pump.

Abstract: In a hand-held motor-driven compass saw, the end of the reciprocating rod is connected to the end of the saw blade by means of a clamping member. The reciprocating rod has a U-shaped cross-section whereby it defines a relatively flat recess into which the end of the saw blade is inserted. The end of the reciprocating rod and the end of the saw blade are surrounded by a protective shield. The clamping member may be displaced along the end portion of the reciprocating rod from outside of the shield so as to release the clamping member or to lock it on the end of the reciprocating member when the saw blade is inserted into the recess formed in the U-shaped reciprocating rod.

Abstract: An apparatus for forming honeycomb-type core strip includes a source of metallic ribbon, form gears for forming a desired configuration in the ribbon and take-up means for taking up the core strip as it is issued from the form gears. Interposed between the source and take-up means is lubricating means for insuring adequate lubrication of the metallic ribbon as it enters the bite of the form gears. The form gears are characterized by a configuration which enables them to impart hinge means to the ribbon which facilitates the utilization of the ribbon in unitary metallic seal constructions wherein a continuous length of the ribbon is bent into helical form.

Abstract: A housing has an inner area defined by end walls, side walls, a top wall, and a bottom wall having a flat inner surface. Inlet and outlet ports open through the flat inner surface. The inlet port is arranged to be connected to a supply source of pneumatic pressure and the outlet ports are arranged to be connected to an actuator. A control member in the housing has a pair of recesses facing the inner surface in association with the inlet and outlet ports. The control member is suspended by a pair of leaf springs which allow a high response of the control member with a low signal pressure. The leaf springs are engineered and tested precisely considering the compression or columnar force acting endwise thereon as a result of the working pressure in the valve. At the same time the leaf springs have lateral deflection sufficient for operation of the control member 54 without buckling.

Abstract: A pressure fluid reservoir comprising a cylinder with a reservoir connection, a piston displaceable in the cylinder and non-contact switch means for indicating piston positions. Between the reservoir connection and the piston, the cylinder encloses a pressure fluid chamber, which is intended for storing a pressure fluid such as hydraulic oil, brake pressure fluid or the like. Opposite the pressure fluid chamber, the piston defines a gas chamber. The non-contact switch indicating means comprise Reed contacts, for example, and are disposed outside the cylinder such that they are longitudinally adjustable along the cylinder. Adjustment is effected by a temperature-dependent adjusting means, embodied for instance as an expansion element. Permanent-magnet actuating means, for actuating the Reed contacts in a non-contacting manner are fixed in recesses in one side of the piston.

Abstract: A rodlike ceramic member of a heater projects towards and into the active tip of the solid electrolyte tube of an oxygen sensor, extending out from the bottom end of the principal insulating member of the sensor which is made of the same ceramic material. Conducting paths of the heater are brought up to a shoulder where the wider insulating part joins with the carrier of the heater, for connection with conductors leading to the end of the main insulator which is remote from the measuring gas and, furthermore, on this shoulder, connections are also made between conducting paths of the solid electrolyte sensor probe and conductors leading to the end of the main insulator remote from the measuring gas. At that end of the main insulator, sleeve connections are made to connection wires for external connections.
