Patent DE-2340066-A1 (DE)
Title: Noise reducing cct for frequency multipliers - has capacitor bridged resistor supplying biasing voltage to VHF diodes of multiplier
Inventor: BRAUNS HERBERT
IPC: H03B19/16
Filed: 1973-08-08
Abstract: The multiplier contains diodes for very high frequencies and their biasing voltage is collected from a resistor carrying a recombination current. This resistor is shunted by a capacitor. A choke may be inserted between the resistor and the diode. A damping resistor may be provided between the first resistor and the choke. Its value is smaller than that of the first resistor by at least one order of magnitude. An input network may be also inserted between the choke and the diode. The diode control of resonator circuit forms a low pass, to which the biasing circuit may be connected.

Title: Foam cushion with pocket for cape and hood - can be used either separately or together
Inventor: HALBAN GEORGE R VON
IPC: A41D3/08
Filed: 1973-09-27
Abstract: The invention is concerned with a cushion made from plastic foam. A plastic sheet is attached along one side of the cushion and is of the same length as the side of the cushion. This plastic sheet forms a pocket for carrying a folded-up rain cape and hood. In order to use the rain cape, it is taken from the pocket, unfolded, and placed over the head. When rolled up the cushion and cape can be carried in the overcoat or jacket pocket. Thus the cape and cushion can be carried together (as according to the main patent) and used together or separately.

Title: Output switching circuit for use with process controller - has outputs from process sensors coupled to switching circuit with indicators and test facility before transmitting to controller
IPC: G01R1/20
Filed: 1973-12-06
Abstract: In any process or manufacturing plant the outputs of a large number of sensors e.g. limit switches, temperature sensors etc. have to be transmitted in parallel to the system controller at specified voltage levels. The output switching circuits transmit from a germinal to the contact of a sensor relay the outputs of which are coupled back to the switching circuit. Internally, the inputs are coupled to resistors, light emitting diodes and protecting diodes. Outputs are to a rest circuit and to the process controller terminals. Voltage levels can either be positive or negative with respect to a null potential line. With the relay contacts closed the light emitting diode is active, unless a fuse is triggered which reduces the output. A NAND gate monitors the condition of all fuses in the switching circuit.
Patent DE-2363338-A1 (DE)
Title: Damped axles for rail vehicles - with damped inertial masses rotating with axles to eliminate transverse vibrations
Inventor: GASCH ROBERT PROF DR ING
IPC: B60B17/00
Filed: 1973-12-17
Abstract: The rotating axles of the rail vehicles are fitted with inertial masses which rotate with the axles and which are free to move axially under damping forces. They are balanced to dampen out any transverse vibrations of the axles, irrespective of the axle speed. They include mechanical dampers, hydraulic systems, electromagnetic or elastic damping. The most common transverse vibration provides sinusoidal forces between the wheel flanges and the rails and can lead to heavy wear and instability of high speed trains. The invention eliminates this vibration and increases the effective speed of the trains.
Patent DE-2365506-A1 (DE)
Title: Multi-thermostat ventilator motor revolution rate control - includes additional auxiliary thermostat connectable to main thermostat
Inventor: ZWICKER WOLFGANG DIPL ING
IPC: G05D23/24
Filed: 1973-06-18
Abstract: The circuit is for a series of thermostats for heating or air-conditioning plant, where the air temperatures in different rooms can be independently controlled by means of the temperature-dependent regulation of the revolution rate of a ventilated motor. The auxiliary thermostats linked to the main thermostat may be reversible via the latter, from heating to cooling operation, or vice-versa, and temperature or humidity may be set for the auxiliaries, independently of the main thermostat, at the operating unit. In a differential amplifier on the operating unit for the main thermostat, reversal between cooling and heating is effected through the throw-over contact of a relay. Room temperature can be individually selected with each thermostat, and change between heating and cooling can be centrally effected.

The bridge has at least one side an upright section directed downward out of the plane of the longitudinally and transversely elastic part of the spring bridge; whose associated sides are supported on associated parts of a frame, with heightwise resilience. The spring bridge can be of cheaper material than the base material.

Title: Insert bearing for leadscrew drive nut - has needle roller bearings locate nut to minimise wear due to side loads
Inventor: FLISIKOWSKI PETER
IPC: F16H25/24
Filed: 1974-02-13
Abstract: Leadscrew drives for translating rotational motion into linear movement employ a nut containing a mating thread profile. Bearings minimise thread wear due to side-loads and out-of-balance dynamic forces. The leadscrew has a buttress type thread that mates with a similar profile in the nut. A needle roller bearing is located in each end of the nut. The needle roller operates in an outer race and runs directly on the flat tops of the thread profile. End plates retain the bearings against axial motion. Alternative designs utilise needle bearings with inner and outer races, and another variation employes plain bushes.

Title: Paint brush head for paint-filled containers - has axial bore leading from container handle to bristles allow even paint supply
Inventor: MAYRHOFER GEORG
IPC: B05C17/00
Filed: 1974-03-29
Abstract: The paint brush is designed with a stock and has a recess for fitting onto the dispensing opening of a paint container or tube and a passage which extends from the recess to open into the brush part. The recess is preferably designed as an axial threaded bore so that it can be screwed onto the paint container which then forms the handle for the brush. The material of the paint container is such that it can be deformed to supply the paint to the brush and in this way the precise amount of paint is always available without having to keep dipping the brush in a pot. Furthermore when painting above shoulder height there is no build up of paint around the stock and thus no disadvantageous dripping.

Title: Copper commutator ring with complex inner and outer profile - made using press tools designed for very long life
Inventor: KANAMARU HISANOBU
IPC: H01R43/08
Filed: 1975-10-03
Abstract: A metal blank is plastically deformed to produce complex profiles on both its outside dia. and in its bore, by pressing in a die. The novelty is that a ring blank is pressed in a die without any appreciable force being applied by male teeth on a punch to the base of a ring of grooves formed in the bore of the blank. The blank pref. undergoes no deformation in the axial direction, the tools employed consisting of a die with the required profile in its bore and a punch located via a guide rod so the internal and external profiles are accurately aligned w.r.t. each other. Used e.g. in mfg. a commutator from a copper ring. The tool design provides a 50-fold increase in tool life as compared with conventional tools, and the wt. of the ring blank is only 40% of that required if the commutator were to be made by turning.
