Abstract: ABSTRACT:    "Dial-Operated PBX Exchange":              Selector modules (multiplexers M1 - M8) formed as integrated modules using C-MOS-technology are used for the switching network which permits full accessibility between lines and stations via electronic crosspoints.  Via individual selector lines specified by an appropriate drive address from a control computer unit (ST), individual subscribers (T0 - T5) in the case of internal traffic are to be connected, and in the case of external traffic any subscribers are to be connectable to any exchange line (Ltg1, Ltg2).  The switch-ing network (KF) is electrically isolated from other functional units by transformers (Ue1 - Ue8) in the subscriber circuits (TA0 - TA5) and in the exchange sets (AS1,AS2).  Central units (audible tone receivers, tone generators) are connected via free selector lines of the multiplexers.    (Figures 1a and 1b)

The timing so obtained is processed by a microprocessor 48 to determine the run-out profile of the tire 16.  The data is further used for determining the average gap d between the green tire 15 and the mold surfaces 20 both at the time of mold 10 closure and at the time of first contact between the green tire 16 and the mold surfaces 20.  This data is then used to regulate the closure rate of the mold halves 10 and/or the inflation rate of the green tire 16. The sensors 32, 34 contemplated include pressure switches 34, vacuum switches, microswitches, linear variable differential transformers and thermocouples.

Abstract: - Abstract -Fluid-Tight Flexible Connection between Hollow Sections A fluid-tight flexible connection to be assembled by simple insertion is described.  It consists of coupl-ings (27, 28) of soft elastic material, inserted in cavities (11) of hollow sections (12, 13) and flex-ible parts (29) of likewise soft elastic material as well as nipples (32) to be inserted in passages (33) of the couplings (27, 28) and transverse passages (34) or the flexible parts (29) with the aid of barbs exert-ing an expanding action, and having an internal bore (39).  The nipples (32) consist of hard material.  The nipples (32) provide a fluid-tight connection between the several parts, namely hollow sections (12, 13), coupling parts (27, 28) and flexible parts (29), which connection has a comparatively high tensile strength in the direction of the cavities (11) by virtue of the barbs.  The adjoining hollow sections (12, 13) can hinge relative to each other owing to the elasticity of the flexible part (29), the maximum hinge angle being determined by the elasticity of the flexible part (29) and its length.    Preferably, the cross section of the passage (33) in the coupling (27, 28) and the external cross sec-tion of the portion of the nipple (32) to be inserted in the said passage (33) are matched to the cross sec-tion of the cavity (11) in question, in order to achieve an improved pressing action in the corners of the cavities (11) as well.

Abstract: PROCEDURE FOR DETECTING BETA-HEMOLYTIC STREPTOCOCCUS ANTIGENS                 Abstract of the Disclosure A method for detecting beta-hemolytic streptococcus antigens in clinical specimens employing nitrous acid extrac-tion and latex agglutination techniques is disclosed.  In the practice of the invention, the antigen is extracted from an uncentrifuged clinical specimen by means of nitrous acid, the extracted specimen is adjusted to an approximately neutral pH and is brought into contact with an appropriate latex aggluti-nation reagent.  In preferred practice the specimen is col-lected on a throat swab and the entire extraction and neutral-ization steps are effected in a microtube in the presence of the swab.  The swab is then employed to remove the neutral-ized, extracted specimen to a slide or the like onto which a few drops of the specimen are expressed by rolling the swab. Detection of the antigen by conventional latex agglutination techniques may then be accomplished optimally using latex spheres onto which high titer rabbit gamma globulin is pas-sively adsorbed.

Abstract: RECIPROCATING MACHINE WITH BOTH PRIMARY AND SECONDARY COUNTER        ROTATING BALANCERS            ABSTRACT          This invention relates to reciprocating machines with both primary and secondary counter rotating balancers wherein, an ordinary crankshaft has one or more crank throws and each crank has a connecting rod driving a reciprocating piston, and a contraweight is mounted at each end of the crankshaft and these rotate around the crankshaft in opposite directions of rotation from that of the crankshaft but at the same RPM as the crankshaft, and the contraweights in cooperation with main counterweights (on the crankshaft) balance the primary recipro-cating inertia forces, and two countershafts (being parallel to the crankshaft) carry secondary balance weights and rotate in opposite directions at twice the RPM of the crankshaft so as to counterbalance the secondary reciprocating inertia forces, and the two countershafts also serve as a transmission and reversor for driving the two said contraweights so as to minimize the total number of gears, shafts, and bearings, and the two countershafts and the two contraweights are all inter-geared to the crankshaft.            INTRODUCTION AND GENERAL NATURE OF THIS INVENTION          A basic problem with reciprocating machines is that there are unbalanced shaking forces as illustrated in Figs. 1 and 2.  A good application of this invention would be in a large single crank double acting compressor machine.  Another application would be a large in-line reciprocating machine of one to three or possibly more cylinders.            The following formula is for the accelleration of a piston in a crank-connecting rod mechanism.  This formula can be found in most text books on the kinematics of machinery. accelleration = r.omega.2  (cos .THETA. ? cos 2.THETA./N) where accelleration = centimeters per second per second r = crank radius or throw centimeters .omega. = rotational speed - radians per second e = angle in degrees that the crankarm has advanced from the top dead center position.        N = ratio of connecting rod length to crank throw.            The well known formula relating inertia force and accelleration is:  reciprocating inertia force = weight x accelleration/gravity

Abstract: ABSTRACT              LOAD BREAK SWITCH WITH SAFETY MECHANISM   A single-phase ground enclosed load break switch for distribution voltages has a hermetically sealed cylindrical metal housing of from 2 to 6 inches diameter which contains an insulating gas under pressure.  The switch has a movable contact assembly to contact a pair of opposed stationary coaxial conductors within the housing.  A rocking bellows at the fulcrum of a crank actuator provides a compact hermetic seal for the actuator without excessive strain of the bellows.  A safety interlock with a visual indicator locks the con-tact assembly in case of a loss of pressure.  Excessive pressure in the switch causes the bellows to be punc-tured with consequent locking of the contact assembly. The switch is small enough to be mounted directly on a transformer or placed into a cable, without the need for a separate enclosure.

Abstract: ABSTRACT           For the extension of busses, use is made of special bus driver and receiver circuits which are capable of (dis-) charging the higher capacitances of longer bus lines more quickly.  However, in such circuit arrangements the direction is reversed by means of special control signals so that data transmission always takes place always in only one direction; or in other known circuits the reversal is liable to give rise to interference signals.  In accordance with the invention, each bus of a local sub-system is connected to the control input of a transistor, notably a PNP-transistor whose collector is connected to O V and whose emitter is connected to the extended bus and, via a resistor, to +U.  Moreover, between the emitter and the base there is connected a resistor which represents the pull-up resistor for the signals produced on the bus, the  signals arriving via the extended bus are coupled onto the bus of the sub-system via this resistor.  Unproblematic reversal of the transmission direction is thus possible.
