Patent DE-2406266-A1 (DE)
Title: Flashing light indicator - has light sensitive devices to vary intensity according to surrounding light
Inventor: BARTOLEIT LOTHAR
IPC: F21S8/00
Filed: 1974-02-09
Abstract: The indicator is designed to mark emergency installations, danger points on roads etc. Energy is economically used by varying the intensity of the lighting according to changing light conditions of the surroundings. The maximum intensity is required at dusk when the flashing indicator is to be recognised at a distance. Light sensitive devices are switched off during daylight hours, reach maximum capacity at dusk, and then gradually decrease in strength as it becomes darker. In a first embodiment a photo-electric cell switches off the supply when daylight falls upon it. A second light sensitive device has a resistance that varies according to the effect of light so that current flow correspondingly changes. The length of the flash can also be modified.

Title: Fishing-line float has multiple compartments - which are separated from each other and consist of buoyancy, equalizing and flood compartments
Inventor: KATT ANTON F
IPC: A01K93/00
Filed: 1974-02-15
Abstract: The three compartments of the float consist of a buoyancy compartment positioned above the equalizing compartment. The flood tube runs through the middle and has holes in the top and bottom part. If the parts are fixed together, the equalizing compartment is filled with water through the flood and discharge holes, until there is only a slight lift, when the holes are tightly sealed. After the cylindrical casing of the buoyancy compartment has been placed on the equalizing compartment and screwed tight, the float is ready for use. If the float is pulled underneath by a bite from a fish, the buoyancy compartment completely fills with water through the floor-tube, thereby eliminating the buoyancy, so that the fish on the end feels no resistance and swallows the bait and hook.

Title: Layshaft gearbox for drill - has axially displaceable layshaft to connect or disconnect lay gears
Inventor: STROEZEL REINHOLD
IPC: B23B45/00
Filed: 1974-03-18
Abstract: The drill has its output spindle driven by a fixed gear in mesh with two gears on a layshaft. One mesh is achieved through auxiliary gears. The drill motor drives the layshaft gear train by way of an input pinion which meshes with a floating gear on the mainshaft which then drives a layshaft input gear via an intermediate gear. Only one of the two lay gears can be driven by the layshaft at any one time and the driving connection is by way of ball closures. Gear selection is made by axial displacement of the layshaft which engages and disengages the ball closures with various detents formed in the lay gears.
Patent DE-2414206-A1 (DE)
Title: Gravity feed magazine for slide projector - with magazine at angle to projector and pivotted mask to turn slides
IPC: G03D15/10
Filed: 1974-03-25
Abstract: The stack of slides is fed into a vertical shaft which is set at an angle to the shaft leading to the slide transport in the projector. The relative angle of the two shafts prevents the slides from falling on the transport mechanism and jamming it. A pivoted plate at the bottom of the shaft has a thickness equal to one slide and when tilted it swings a slide to line up with the projector shaft so that the slide falls onto the transport mechanism by itself, and without danger of jamming. The slide transport mechanism can then be of a simple design which does not have to drag slides off the bottom of a stack.

Patent DE-2514607-A1 (DE)
Title: Insulating lacquer coating for electrical windings - esp in transformers, contains flakes to improve electrical resistance, also conducting powder
Inventor: TJERNSTROEM OVE
IPC: B05D7/20
Filed: 1975-04-03
Abstract: A method of making an insulating lacquer coating on an electrical conductor by an electrostatic process is as follows: the insulating lacquer used contains a certain quantity of an agent having a large specific electrical resistance and also a certain quantity of an agent having good electrical conductivity. The insulating lacquer may be applied in one or more layers; in particular a first layer contg. an agent possessing high specific electrical resistance may be applied, followed by a second layer cong. an agent having good electrical conductivity. The high specific electrical resistance may be obtained by adding, esp. in flake form, mica, aluminium oxide or the like. Carbon dust may be added as the material possessing good electrical conductivity. Esp. used for insulating an electrical conductor, where the insulating lacquer is to be surrounded by another medium possessing a considerably lower dielectric constant, for example oil in a transformer. By adding to the lacquer a material which imparts to it semi-conducting properties, these properties have a compensating effect upon the electrical field, so that the specific electrical loading of the medium possessing the lower dielectric constant, in this case oil, is reduced. The addition of the mica or other flakes considerably increases the electrical resistance and also the mechanical strength of the lacquer, so that a thinner lacquer coating can be used. This reduction in thickness of the lacquer, however,results in a higher electrical loading in the oil. The addition of carbon powder as a conducting medium to the lacquer compensates this increased loading.

Title: Small water treatment appliance - with water powered rotor cutting off water flow through reagents intermittently for better dwell
Inventor: GOTTENBUSCH AUGUST
IPC: B01J47/024
Filed: 1975-08-12
Abstract: An appliance for water treatment contains the reagents for the treatment (ion exchangers, active carbon) in a chaber trhough which the water passes. A flow retarder is arranged in the path of the water flow which intermittently interrupts the flow of water through the reagents. This is a pref. rotating valve which is driven by a small water turbine. The times of standstill give the reagents time to act on the water in a molecular mass exchange reaction. The necessary flow rate is set as an average in time; the intermittent action results in much better effect than a sustained flow.

Title: Brushless DC motor speed control system - uses control and reference pulses fed to bistable switch to interrupt supply
Inventor: STEINBUSCH HANS ING GRAD
IPC: H02P6/10
Filed: 1976-03-02
Abstract: Electronically commutated brushless motors are used to drive tape recorders, punched tape readers and similar apparatus. A pulse train whose frequency depends on motor speed but whose pulse width is inversely proportional to speed is compared with a second, reference, train of the same frequency but having fixed pulse width. The comparator operates a bistable switch such that if the fixed pulses are longer than the variable control pulses the motor supply is interrupted, whilst if the opposite is the case the motor supply is maintained. Two modes of operation therefore exist. In the normal range the motor control operates in known manner the pulse applications being load dependant. At sub-synchronous speeds the motor supply is maintained in the 'on' state until synchronism is again established. At super-synchronous speeds the supply to the windings remains off until normal conditions are re-established.
