Title: Bottle separator for conveyor - has parallel bands of conveyor moved at different speeds at approach to guide walls
Inventor: BARGEL GUENTER ING GRAD
IPC: B65G47/68
Filed: 1978-07-10
Abstract: The separator divides vessels e.g. bottles or jars, moved in several rows extending next to each other. The flow of vessels in front in the direction of movement in one or more tracks in accordance with the pre-determined throughput is withdrawn at a relatively high speed. The following wider flow of vessels follows on at a relatively low speed. The flow of vessels remaining in the intermediate area is steadily accelerated at an incline to its original movement component. This intermediate area is kept by the variable forward speed of the wide flow of vessels within a continuously self renewing formation.

Title: Ultrasonic cleaning of parts which contact transducer-support - involves lower energy levels and shorter treatment times through direct contact with vibration surface
Inventor: GRANSELL AAKE
IPC: B08B3/12
Filed: 1978-10-14
Abstract: Articles are ultrasonically cleaned by exposing them to an ultrasonci field as they are transported through a bath of liq. The transport path is formed by a member which has ultrasonic transducers mounted on its undersurface so that the articles receive direct vibration from the member when they mech. contact the member during transport. The time duration of passage of articles along the path can be controlled, e.g. by altering the inclination angle of the member. The transport path may be defined by an endless belt conveyor, a gutter or a pipe. Used in cleaning of mass produced parts, e.g. screws, nuts, bolts, ball-bearings and precision parts. Since the parts are brought into mechanical contact with a member that mounts an ultrasonic transducer, efficient cleaning can be effected at lower energy levels and during shorter treatment times. Cavitation damage is reduced owing to shorter treatment times and lower energy levels.

Title: Three ball rotating pendulum display for clock - has unified suspension mounting and pendulum stop preventing malfunctioning through rough handling
Inventor: FEHRENBACHER WOLFGANG
IPC: G04C3/033
Filed: 1979-04-19
Abstract: The three ball rotating pendulum is connected to torsion wire or tape held in a fitting that contains a spring permitting natural adjustment in the vertical direction. The pendulum is restrained from excess rotation by a projection that can abut a fixed pin. The pendulum has a fixed natural frequency of about eleven seconds but is forced to oscillate with a frequency of ten seconds by means of an intermittent force applied by six spokes of a wheel driven by the second shaft of the clock. This wheel is driven via a spring which ensures smooth application of just sufficient force to turn the pendulum at this frequency.
Patent DE-2926738-A1 (DE)
Title: Interferometric surface irregularity shape and sign determination - using polarised phase-shifted components forming line pair interference pattern
Inventor: FROSCH ALBERT DIPL PHYS
IPC: G01B9/02
Filed: 1979-07-03
Abstract: The interferometric method of determining the shape and sign of irregularities or inclinations in a surface involves use of a measurement and a reference beam. The desired parameters are measured very accurately and rapidly and irrespective of all external influences. The results are evaluated quickly and with simple equipment. -The measurement or reference beam is polarised into two different components. One component is phase shifted by less than half a wavelength before combining it with the unpolarised beam. The two interference fields so produced are separated using polarising elements to produce two interference patterns. The two patterns are finally combined into a pattern of line pairs with relative positions defined by the phase difference impressed on the two components.

Title: Rotating heat exchanger with heat storage plates - is made from quartz alloy to withstand high temp. fluctuations
Inventor: HAEBERLE WILHELM
IPC: F28F21/04
Filed: 1980-04-19
Abstract: Heat exchanger of the type which receives heat from liquids or gases, stores it in plates or tubes of solid material, and then transfers it to a second medium, has the solid heat carrier composed of thin-walled tubes, thin perforated plates or discs, or layers of corrugated, indented or similar strips (43), alternating with smooth or differently corrugated strips (42); all these components are of quartz, a quartz alloy or synthetic quarts. The quartz may be alloyed with metals of high thermal conductivity, for example silver, copper, or aluminium. Tubes may be of hexagonal cross-section. Parallel perforated plates may have the perforations either in alignment or staggered from one layer to the next. In a preferred embodiment (as illustrated) the layers of corrugated and/or plane strips are in the form of a rotary heat exchanger. The ratio of useful surface to volume is small, resulting in a compact arrangement. By alloying with only 2% silver an increase in thermal conductivity of 50% is obtained over that of pure quartz.

Title: Evaluating system for target hits - involves reflection light barrier, moved along two concentric circular path sections relative to rotary axis through hit hole
Inventor: HUESCHER GEORG
IPC: F41J5/02
Filed: 1980-07-08
Abstract: The system moves a reflection light barrier (36), or similar device in radial direction to the kit hole up to the light-dark boundary between the dark mirror and the bright background. Then the barrier is moved along this boundary by an optical follower control. With the stationary target disc (40) the light barrier is moved over two concentric circular sections (36e,36l), whose concentricity is related to the rotary axis containing the hit hole (56). Their radii correspond to the extreme values of the axial spacing of the bright-dark boundary (58). The radial path of the light barrier between both circular sections is halved and forms the distance rate of the hit hole centre from the disc mirror centre (54). Pref. the light barrier performs two circular courses about the hit hole axis in opposite direction during a measuring cycle. The rotary drive for a revolution may start at the moment when the light barrier has reached the bright-dark boundary.

Title: Removing salts residues from vulcanised prods. - by washing in two stages with partial removal and replacement of wash liq. in first stage
Inventor: PRUELLER HELMUT DIPL CHEM DR
IPC: C08J7/00
Filed: 1980-09-16
Abstract: Removal of salts residues from objects vulcanised in a salts bath, esp. rubber articles, and also treating the resultant washing liquid, is claimed. Two separate washing baths are used; in the first bath the articles are washed, opt. also cleaned with brushes or other mechanical means; from this bath the liq. is continuously pumped in a circuit, from which a portion of the liq. is abstracted and fresh make-up liquid (I) is added. The abstracted portion of washing liquid is evaporated and the resultant salt is fed back into the treatment bath. In the second bath (2), the articles are again washed to complete the removal of the salts residues. Pref. the articles are sprayed as they leave the first zone and mechanically cleaned also at this point. In the first bath the washing liq. may be cooled by heat exchange with a cooling liq. which also serves as a washing liq. for the second zone. The amt. of liq. abstracted from the first zone is 5-100 litres/hour. Used esp. for treating rubber sections etc. which have been vulcanised is a bath comprising potassium nitrate and toxic sodium nitrite. Of prior art methods of oxidising the nitrate to nitrate, then sepg. the latter by ion exchange etc., this method is much more economical.
