Patent DE-2344012-A1 (DE)
Title: Watch balance spring attachment - is fastened to stud by adhesive or soft solder in large hole
IPC: G04B17/32
Filed: 1973-08-31
Abstract: The outer end of the balance spring of a watch can be attached to its stud in such a way that the spring is fixed free of stresses and that no readjustment of the mechanical zero is required. The balance spring is filed through the slot on the index and the end is pushed through a large hole in the stud. This hole is filled by a rapid setting adhesive or by an easily fusible solder which is heated for two seconds. The untensioned, freely moving balance spring thus has one end covered over and, as the solder cools, is firmly fastened to the spring stud. The fixing of the spring in this manner occasions no tension so that the usual after-adjustments are not necessary.
Patent DE-2352491-A1 (DE)
Title: Protection cct. for amplifier class-B output stage - has monostable transistor discharging capacitor to operate relay that unloads output stage
Inventor: KARBOWSKI GEORG DIPL-ING
IPC: H03F1/52
Filed: 1973-10-19
Abstract: The protection circuit forms part of a system that delays the connection of a loudspeaker to the amplifier when the equipment is switched on, thereby avoiding the loud click. The delay capcitor begins charging when the supply is switched on, and after a given time turns on the transistor that operates the relay. The relay connects the loudspeaker to the amplifier class-B output stage. The amplifier is monitored for overloads and an overload signal is produced which operates a monostable flip-flop. One of the monostable flip-flop transistors turns on and short circuits the delay capacitor, thereby turning off the relay transistor and allowing the relay to open and disconnect the loudspeaker from the amplifier.
Patent DE-2360544-A1 (DE)
Title: Uniform through-heating of flat foils, fabrics or yarn sheets - involves admitting hot air from above and below, at equalized speed and heat content
Inventor: FUCHS HELMUT DR ING
IPC: D06C7/00
Filed: 1973-12-05
Abstract: Flat lengths, foils, yarn sheets, or textile fabrics are uniformly heated through; the material to be treated is conducted in a flat plane heating space and is acted on uniformly from above and below by heated air streams, outflowing over the width with uniform speed and heat content from a nozzle-like opening. The heat and speed distributions are equalised by turbulent mixing streams in the suction space using secondary flows due to the trapezoidal suction space cross section, and by turbulent mixing streams in the heat exchanger produced by the spiral flow from the diffuser contour during passage through parallel rod-shaped thermal active elements. Uniformity of end product quality is ensured.

Filed: 1973-08-27
Abstract: One or more ink reservoirs may be provided each with a ductor roller (74) whereby in each case the toothed rack (132) meshes with a pinion (131) on the ductor roller is guided linearly in a direction of movement under the action of a spring (143) and in addition forms the cylinder (134) for a fixed plunger piston (136) incorporating the pressure medium supply lines (137). The stroke of the toothed rack can be varied using an adjustable stop (145) in the form of a screw which passes through a threaded borehole (144) in a fixed stop. The control system is particularly designed for indirect printing processes such as dry offset.
Patent DE-2402967-A1 (DE)
Title: Piezoelectric material quality testing method - based on loss factor being function of temperature and frequency
Inventor: BUTUSOW WLADIMIR P
IPC: G01R29/22
Filed: 1974-01-22
Abstract: During measurement one of the parameters is kept constant, and the value of the other parameter is derived, at which the dielectric loss factor is maximum. The material quality is determined from this. Frequency is used at the parameter for which the loss factor maximum is determined and temperature is the constant parameter. The characteristic parameter can thereby be measured quickly, accurately and objectively. The quality control can be employed for natural as well as artificially produced piezo quartz and other piezo pieces. Neither the surface quality nor the shape or size effects the resultant of the control measurements.

Title: Electronically controlled resistor cct. - contains field-effect transistor source-drain path working with small control time constant
Inventor: WERMUTH JUERGEN
IPC: H03G1/00
Filed: 1974-01-26
Abstract: A FET gate is connected to a control voltage and also to a tapping of a voltage divider in parallel to the FET source-drain path. Half of the A.C. voltage applied to the FET source drain path is applied to the FET gate. A separating amplifier with an even number of inverting stages is so inserted between the FET gate and the voltage divider tapping, that an isolating capacitor cannot be discharged by the D.C. control voltage. The control voltage is applied to the amplifier second stage. The separating amplifier gain is such, that even if the voltage divider resistors are not equal, half of the A.C. voltage across the FET source drain path is applied to its gate.

Title: Fan cowl for electric motor with exterior cooling - has set of ribs at inlet which are of triangular cross section
Inventor: SAGRATIAN MAKS ARISTAKESOWITSC
IPC: H02K9/00
Filed: 1974-04-01
Abstract: The application is to motors with external cooling ribs on the stator frame over which air is blown by a fan attached to the motor shaft. A cowl deflects the air from the fan causing it to flow axially along the stator case. The aerodynamic performance of the cowl is improved by paying attention to the design of the ribs around the air inlet grile at the end of the cowl. The axial thickness of the grille is greater than that of the cowl wall, and the ribs are given a triangular cross section with a point of the triangle facing the air inlet stream. Typically this point of the triangle is some 5 deg.

A flexible tape or wire (1) is fixed at one end and the free end tied to a tensioning spring (2). Each digit of parallel binary information is supplied to an electro-mechanical solenoid (4) that deflects the tape vertically and produces a lateral displacement of the free end of tape. Rollers (3) restrain the tape the stroke of each actuator is set to produce a linear movement of the tape according to the corresponding bit weighting.

Title: Adjustable spacer using tapered elements - has two relatively rotatable discs each having mutually inclined endfaces
Inventor: LIPPERT HORST
IPC: F16M7/00
Filed: 1974-10-17
Abstract: Adjustable spacer, esp. for making good uneven surfaces in machinery assembly, is made of two discs (1, 2) each having end faces lying in mutually inclined planes so that when the discs are assembled coaxially their mutually remote end faces are parallel while their proximate end faces make contact in a plane inclined to the parallel faces.

Patent DE-2517269-A1 (DE)
Title: IC engine fuel injection regulator system - exhaust oxygen probe signals are switched off until engine reaches working temperature
Inventor: HERTH HARRO
IPC: F02D41/14
Filed: 1975-04-18
Abstract: The exhaust system contains an oxygen probe to give a signal which is analogous to the exhaust oxygen content to the electronic regulator in order to alter the fuel injection dwell to produce a correspondingly richer or weaker fuel injection. A time switch (4, 6) is included in the circuit to isolate the oxygen probe until the engine has reached working temperature otherwise the probe high resistance under cold circumstances could cause a high tension drop on the transistor (T9) base and lead to a weak mixture signal being formed. The injection dwell is regulated by a comparator switch (1) to give an average predetermined output signal which is gradually superseded by the oxygen probe signals via a miller integrator consisting of two transistors (T22, T23) and a capacitor (89) as the engine reaches working temperature.

Title: Acceleration and braking control for train - with logic control for even force and minimum braking distance
Inventor: UEBEL HELMUT DIPL ING
IPC: B60L15/10
Filed: 1975-05-23
Abstract: The train is fitted with speed and inertial monitors to determine the exact dynamic state of the vehicle. A simple logic control is linked to the monitors and to the brake modulators and throttle control so that a smooth acceleration /braking control is achieved. The vehicle speed is braked in such a way that a maximum retardation is not exceeded, and with the optimum speed at any point being equal to the square root of twice the product of retardation and braking distance. During acceleration a maximum acceleration limit is not exceeded. The vehicle is thus moved with a maximum of comfort for the passengers. For braking control the driver sets the final selected speed on the control lever, and the automatic system follows the programmed sequence.
