Title: Dot printer for multiple channel recorders - uses reduced head transport torque and writing pressure with fibre pens
Inventor: HOEHL RUDOLF
IPC: G01R13/10
Filed: 1976-02-07
Abstract: A dot printer for multi-channel recorder devices using the compensation method is designed for reduced wt. and vol. by using writing heads with fibre pens. This is achieved by reduction of the torque required to move the heads to new recording points and limiting the force with which the pens are applied to the recording medium. The printer has a mounting for a rotatable writing head (8) and a guiding device (6, 7) parallel to the recording medium transport drum (5). The writing head is raised from the medium between printings. The mounting consists of a rotatable insert with two rigidly connected arms, one (10') carrying the head and one (10") extended with a spring plate (11), and non-rotating slots (9) sliding along the guide.

Title: Mechanically coded telephone dialling system - has cam-shaped stop surface for deflection of contact spring set control spring
Inventor: AWAKOWICZ ERWIN
IPC: H01H13/74
Filed: 1976-02-26
Abstract: The contact spring set (6) is actuated by shifting of a link motion (7) which carries an eccentric cam disc (8). This disc forms the stop surface for deflection of the control spring (15) of the contact spring set, and is rotatably mounted on the link motion. The positive securing of the cam disc angular position is provided by safety elements(12, 13) in the form of a ratchet and pawl. Pref. the cam disc has an axial bore for inserting onto an axial bolt (9) on the link motion at right angles to its shifting direction. The bolt and the cam disc are both provided with complementary latching protrusions or depressions (10, 11) for securing the disc axial position. The axial length of the disc extends over that of the bolt so that a free space remains in the bore region away from the link motion.

Title: Blade changing tool for wood chipping machine - has blades supported against spring loaded pressure plate and released by driven lever
Inventor: SYBERTZ HANS
IPC: B23Q17/22
Filed: 1976-02-27
Abstract: The wood chipping machine incorporates a blade shaft and an auxiliary device for changing the force-locked blades which are supported against spring-loaded pressure plates. Each blade pressure plate is pressed by a compression spring into a form-locking position with the shaft unit and against the blade and itself houses a compression spring braced against the blade's chipping face. An independently driven lever on the auxiliary device arm carries a pressure tongue to act vertically on the plate, against its spring action. This combines with the pressure batten to match the combination of flywheel cotter and pressure plate. When the pressure batten lies on the cotter, the tongue pressure face in the inactive position is at a small radial interval from the plate's open surface.

Title: Side wheel steered agricultural tractor - has auxiliary steering axle which raises one steering axle from ground contact to provide conventional steering
Inventor: KRUEGER GERHARD
IPC: B60S9/20
Filed: 1976-02-27
Abstract: The tractor is steered by either braking or reversing the two side wheels. The vehicle is able to turn in its own length but causes damage to ground surface and highly strains all mechanical parts. An additional steering system is provided at the rear of the vehicle chassis. The vehicle may be steered conventionally, when required, by foot pedals. The auxiliary steering is carried on a sub-frame linked to the main chassis. A hydraulic lift (18) raises the auxiliary steering clear of the ground when not required. When the auxiliary steering is brought into use, the hydraulic lift is reversed to press the auxiliary steering onto the ground.

Title: Electric drive for self processing camera - has clutch for shutter and claw drive and time delay for processing rollers with automatic return for next exposure
Inventor: ETTISCHER HELMUT
IPC: G03B17/52
Filed: 1976-03-19
Abstract: The self processing camera has a simple drive mechanism powered by a single electric motor and operated from the release button. This operates the shutter release and moves a spring loaded lever to turn a control cam wheel. The wheel couples the drive to the claw mechanism which drags the top film pack and passes it to the processing rollers. At the same time the shutter is reset. A clutch disengages the first part of the drive while maintaining the processing roller drive for a time sufficient to pass the film pack through. After the time delay the drive is stoped and the shutter release button and the control cam returned to a position to allow the next exposure to be taken.

Title: Materials investigated by particles in state of excitation - giving Doppler effect in gamma emission to indicate particle velocity
Inventor: HAUSER ULRICH PROF DR
IPC: G01N23/222
Filed: 1976-03-19
Abstract: The gamma spectrum emitted by recoil nuclei or nuclear fragments is modified by the resultant doppler effect for the material under investigation so that it can be used for specific analysis of the nature of the specimen. The moving, gamma-emitting fragments are pref. released inside the specimen by a nuclear reaction, the reaction may be produced by implanting he specimen with a special isotope, in which the reaction occurs, or sources of slor or fast neutrons may be planted in or on the material, to produce local nuclear reactions. Used for investigating the structure surrounding carbon atoms in steel. In oil prospecting a fast neutron source in a borehole will indicate the presence of oil, oil-water mixts. oil-sand mixts. gas or mineral carbonates. Deeper penetration can be achieved in the analysis than with previous methods.

Patent DE-2621532-A1 (DE)
Inventor: FUJITA HIRO
IPC: G04G7/00
Filed: 1976-05-14
Abstract: A frequency standard for an electronic timepiece comprising a low frequency oscillator and a high frequency oscillator of which the frequency is an integral multiple of a predetermined frequency of the lower frequency oscillator. A phase difference detector is coupled to the lower and higher frequency oscillators to produce a signal occurring at intervals depending on the phase difference between the two oscillators. A frequency divider is provided to divide down the frequency of the signal by the integral multiple to produce a phase difference signal. The phase difference signal is algebraically added to the lower frequency oscillator signal to generate an output signal of which frequency is equal to that of the high or frequency oscillation signal divided by the integral multiple.

Title: Two stage amplifier protection circuit - has direct negative feedback from output to inverting input converting circuit to switching operation
Inventor: POSSELT HEINZ
IPC: H03F1/52
Filed: 1976-12-27
Abstract: The amplifier has a negative feed-back and is protected against overload and short-circuit.

Patent DE-2704533-A1 (DE)
Inventor: KLAUTSCHEK HERWIG DIPL ING
IPC: H02P21/22
Filed: 1977-02-03
Abstract: The device is used for controlling the position of the stator current vector of a rotating-field machine which is supplied with an impressed current via an invertor. It has two sawtooth-waveform generators whose output signals are compared in the input circuit of a limiting-value signalling device. The output signal of this limiting-value signalling device operates a changeover device in order to change the stator current vector position. The drive unit for supplying the voltages for the valves of the invertor contains two ring counters (10, 11) to which the output signal of a voltage/frequency converter (9) is applied. The control device makes it possible to operate the machine in both rotation directions. For this purpose, it has an evaluation circuit (101) which is used to identify the polarity of the frequency control voltage (Un), which is provided upstream of the voltage/frequency converter (9). Its output signal (b) is passed to the forward/backward input of the ring counters (10, 11). This device is suitable, for example, for use in rolling mills, railway drives or roller beds. <IMAGE>

Title: Mechanical insertion of conducting pins in circuit board holes - uses wire pulled from spool, widened at end, broken off and pressed into board hole
Inventor: PIWERNETZ ROLAND ING GRAD
IPC: H05K13/04
