Title: Encased electromagnetic contactor with stationary core - has moving parts on armature holding armature in proper position
Inventor: STIGLITZ ROBERT
IPC: H01H50/32
Filed: 1975-04-26
Abstract: The electromagnetic contactor is mounted in a housing and has a stationary magnetic core and a moving magnetic armature with a guideway. To the armature are connected contacts with moving parts whose resetting springs have rising spring characteristic. The contacts moving parts are of such design that, if the minimum attraction tension is not reached, the moving armature (3) is held in the OFF position during switching on. For this purpose a spring arm with a lug is preferably formed on the guideway (4). In the OFF state the lug reaches behind projections (8) and holds the moving parts of the contactor until the minimum attraction tension has been reached. At least one compression spring (7) may be provided for pressing the arm against the projection s).

Title: Clamp for concrete reinforcement cold working - has rapid acting hydraulic bar clamp actuator preventing damage to bar
Inventor: AENGENEYNDT WOLF DIPL ING
IPC: B21D11/15
Filed: 1975-05-17
Abstract: The clamping arrangement for twisting machines used for cold working of concrete reinforcement bars by twisting about the longitudinal axis ensures non damaging clamping while preventing slipping. The clamping jaws have very short transition time between the open and clamped state of the jaws and the arrangement also prevents reverse rotating when the jaws are being opened. The clamping system hydraulic cylinder (8) has short clamping travel and it is actuated by the pressurised fluid storage arrangement (10) in the shortest possible time and it operates the clamping jaws (2) by a lever system. This clamping system is roted at the end of the twisting movement in the opposite direction to twisting until the residual torsion stress is eliminated and the jaws are opened only after that.

Inventor: CAROLL WALLACE E
IPC: G01N21/27
Filed: 1975-06-30
Abstract: Light from a light source is passed through the sample and collected. an electric output signal is generated, whose amplitude is proportional to the sum of a constant and the logarithm of light transmission. The output signal is subtracted from a first quantity, and the result is multiplied by a second quantity, thus delivering the final result. The circuit arrangement includes a laser light source (4) with a beam passing through the cuvette (8) containing the sample to a selenium or silicon photocell detector (10), whose terminals are connected to potentiometers (20, 24) and thereafter to a digital voltmeter (28).

Partic. used for inspecting the interior of a liq. -contg. reactor pressure vessel, after the top closure has been removed. The lower end of the mast mounts the inspection device on a rotating arm. The arrangement enables the mounting point of the mast to be reduced to the level of the top of the pressure vessel, so that the mast is more stable and accurate in its position.
Patent DE-2544801-A1 (DE)
Title: Excess loading protection circuit - uses derivative of saturated output of line transformer with additional voltage injection from auxiliary transformer
Inventor: HALAMA WALTER DIPL ING
IPC: H02H3/26
Filed: 1975-10-07
Abstract: A transducer (T1, T2) gives the first derivative of the saturated output of the line current transformer (W1, W2) and employs it to control a square wave generator (S1, S2) feeding a phase comparing network. Under certain circumstances, however, the transducer output can be virtually zero. In such a case control of the square wave generator may be lose and the protection rendered ineffective. This occasional condition is overcome by including the primary winding of an auxiliary current transformer (T1', T2') in series with the transducer primary, and adding part of the secondary output to the transducer output. A voltage divider (R1, R1'; R2, R2') may be put across the current transformer terminals for this purpose. The resultant signal has precise zero cross-over points and always has a finite value above or below these points.

Title: Noise damped valve closure sealing washer - has hollow chamber behind washer connected to water in valve housing
Inventor: MERZ KLAUS-PHILIPP DIPL ING DR
IPC: F16K47/02
Filed: 1976-04-03
Abstract: The water outlet tap has a screw valve. A sealing washer made from flexible material is placed on the closure element and can oscillate for noise suppression against a hollow cavity. The clamping method of the washer ensures good sealing effect and long life for the washer.

Title: Density storage disc piezoelectric scanner - has scanning tip and transducer for reproduction of modulation in grooves
Inventor: LAUE ECKHARD
IPC: G11B3/46
Filed: 1976-04-29
Abstract: The scanning pin of hard material, e.g. diamond, with a record-playing tip is coupled to a piezo-electric transducer by an elastic intermediate layer. The inherent frequency of the elastically secured scanning pin lies in the carrier frequency range. The elastic intermediate layer can be damped so that the resonant curve overlaps the entire transmission band. In contrast to ordinary diamond-fitted devices, the scanning pin coupled in this way scans the modulation virtually without deformation of the groove.

The spark can be obtd. from an electric battery or accumulator using a single cable and appts. producing a high voltage, e.g. an ignition coil. Used in optical communication technology, where the ends of fibres are joined together or to optical transmitters and receivers, where min. attenuation at the joint is required. A smooth fracture is obtd. at 90 degrees to the axis of the fibre.

Title: Vacuum heat treatment furnace - where work chamber is divided into five zones, each with individual electronic temp. controller
Inventor: KNIERIEM ALFONS
IPC: C21D11/00
Filed: 1976-07-08
Abstract: The temp. in a heat treatment furnace is controlled during heating up, esp. in a vacuum furnace, using a temp-time programme in five separate heating zones (I to V). Zone (I) is heated using a reference temp. (Tr); and its actual temp. (Ta) is continuously measured and used as a reference temp. for the remaining zones (II to V). The ref. (Tr) is pref. based on a variable temp.-time programme. In the pref. furnace, each zone (I to V) has its own heating elements and thermocouples; each thermocouple is connected to a transducer feeding a controller linked to an amplifier adjusting the current fed to the electric heater elements in each zone. Uniform temp. distribution is obtd. in the furnace during heating up, and the overheating of some workpieces, e.g. in the top part of the furnace, is prevented.

Title: Compact sifting appts. esp. for laboratory use - has single axial blower producing forced air stream for separating light and heavy particles
Inventor: KNOLLE WILHELM PROF DR ING DR
IPC: B07B4/08
Filed: 1976-06-21
Abstract: The sifting appts. for sifting granular material comprises vertical sifting channel (13) to which the material to be sifted is fed via a supply mechanism wherein a single axial blower (7) is mounted beneath the channel to produce a forced air stream which separates the heavy particles from the finer particles. The pressure flow from the pressure chamber suitably branches off above the fan blower so that a faster stream is produced compared to the main pressure stream. This faster stream is guided up on the wall beneath the supply opening for the sieved material in the channel so as to loosen up the material which has been supplied by the feed mechanism.

Title: Radio communication system using personal transmitters - uses pulse pattern on common frequency to identify caller
Inventor: GILMOUR WILLIAM DUDLEY
IPC: G08B13/22
Filed: 1977-03-10
Abstract: The radio communication system links a number of persons carrying a transmitter and a common centre. The transmitter provides a basic call - back to the centre notifying a need for assistance or a particular operation to be carried out. All transmitters work at the same frequency, the identity of each being labelled by breaking the basic carrier frequency into pulse trains, the number of pulses in each such train providing the identification. The transmitters, which can be carried in a pocket, are manually switched on or off. The central receiver is clock based and uses a counter and comparator to process the incoming transmissions and provide an alarm activation.
