Title: Coin tester with magnetic stage to test alloy - has convex faced magnet to reduce friction with coins
Inventor: STROBEL ROLF
IPC: G07D5/00
Filed: 1975-10-13
Abstract: The coin testing machine for the detection and rejection of unwanted or false coins has a feed line along which the coins are fed past known types of detector to check the weight, the diameter, and the embossing, and in addition, at the end of the path they are fed past a convex-shaped magnet (2) to check the alloy of which the coin (5) is made. The magnet is a permanent bar magnet with its longitudinal axis perpendicular to the line of the coin feed. Its convex face reduces friction with the coins passing it. The system detects coins of incorrect alloy brought up to correct diameter by an annular ring.

Title: Electric ignition monitoring device for domestic gas appliances - has auxiliary spark gap closed when flame heat present and has replaceable gas diode
Inventor: WONISCH FRANZ
IPC: F23N5/12
Filed: 1976-08-19
Abstract: The monitoring device for electric ignition systems on (e.g.) domestic gas appliances is for systems using an ionisation gap and a thyristor controlled relaxation oscillator to initiate spark generation in the event of flame failure. Proper functioning of this ionisation gap is monitored by fitting the electrode, pref. doubling as ignition spark electrode, with an auxiliary spark gap built into its insulating holder. When flame heat is present a thermophysical device closes this gap; however should the flame go out and the ionisation gap not function (e.g. due to fouling) the open auxiliary gap will take its place. A semiconductor or gas diode can replace the auxiliary spark gap.

Title: Sewing machine lower thread monitor - uses two-position sensor with signal trip if broken thrread allows a third position
Inventor: TAJIMA IKUO
IPC: D05B51/00
Filed: 1976-12-03
Abstract: The appts. registers a break in the lower thread of a sewing machine, when executing a chain stitch seam. The sensor is pivoted in a reciprocating motion, and has two sections. The first section moves between two settings, if the sensor is turned, where the lower thread follows its normal pat between these two points, with a drive to operate the sensor. The second section is used to trigger an output signal if the sensor moves past the normal point where the lower thread would be, on moving from the first to the second point, thus indicating a thread break. This allows the lower thread to be monitored positively, while occupying little space below the lower plate of the sewing machine.

Title: Iodine monitor with two scintillators for distinguishing components - according to ease of adsorption on different filters, used esp. for measuring radioactive iodine content of air
Inventor: WILHELM JUERGEN DIPL CHEM
IPC: G01T7/04
Filed: 1977-03-17
Abstract: An iodine monitor for continuous individual measurement of iodine components in the atmos. operates by a scintillators which detect the quantum radiation produced as the iodine decays.

Title: Promoting reactions in turbulent conditions by further mixing - induced by intermittent application of pressure waves
Inventor: REXROTH ALFRED
IPC: B01F33/40
Filed: 1977-03-23
Abstract: Influencing chemical and physical reactions between reaction partners utilises turbulent motion, e.g. in fluidised bed calcining or sintering processes. To promote the forming and/or transforming of turbulent vortices and for regulating the mixing process, the reaction partners are intermittently subjected to pressure waves. Specifically, waves of frequency 30-109 Hz are used for gases and vapours, and of frequency 30 Hz - 20kHz for liquids and smelts. The imposition of pressure waves upon the reacting fluid improves mutual penetration and mixing of the reaction partners and thus results in a more intense reaction.

Title: Conversion of sulphur di:oxide and hydrogen di:sulphide to sulphur - with alternating phase of sulphur sepn. and catalyst regeneration
Inventor: AL-MUDDARRIS GHAZI RASHID
IPC: C01B17/04
Filed: 1977-04-30
Abstract: Sulphur dioxide and hydrogen sulphide are converted to elemental sulphur at a raised temp. under the sulphur dew-point in a catalyst bed. The average amt. of conversion is maximised by alterating a reaction phase with simultaneous sepn. of the sulphur and a reaction phase with simultaneous regeneration of the catalyst bed by removal of the sulphur. Pref. the reaction phase with simultaneous regeneration takes place at a temp. above the sulphur dew-point and the reaction phase with simultaneous sepn. of the sulphur takes place at a temp. below the sulphur dew-point. Pref. the catalyst bed is arranged as the last step in a multistage claus unit to give average conversions of 97-99.5%. The process gives a higher conversion to elemental sulphur in the Claus process and results in a final gas contg. fewer impurities.

Title: Fluid leakage indicator for storage tanks - delays interruption of outer test chamber evacuation after reaching lower threshold limit (SW 18.9.78)
Inventor: NICOLAI WALTER
IPC: B65D90/503
Filed: 1977-04-30
Abstract: The system indicates fluid leakage from a double-walled storage tank, having an outer wall enclosed by fluid and forming a test chamber to be monitored for fluid penetration. A vacuum is maintained in the chamber by an exhauster via an exhauster pipe leading to the bottom of it within a desired range, and a signal is emitted stopping evacuation when a lower threshold limit has been reached. Interruption of evacuation is delayed for a fixed or adjustable period after this limit has been reached, so that the vacuum continues to increase in the meantime, and any fluid in the test chamber is sucked up.
