Title: Particle size analysis of dusts in gases - consisting of two cyclone separators in series followed by filter
Inventor: SOLBACH WERNER DR ING
IPC: G01N15/02
Filed: 1975-02-28
Abstract: Process for particle size analysis of dusts dispersed in gas streams consists of passing the dust laden gas consecutively through several, at least two, cyclonic separators with known characteristics and finally through a fine filter, e.g. a ceramic or paper filter. From the degree of separation achieved in the cyclonic separators and knowing their characteristics, it is possible to determine particle size distributions. All or some of the separators before the fines filter can have the same characteristics. The evaluation is carried by means of the known Rosin-Ramnder-Sperling distribution function, using analytical or graphical methods. Before the first cyclonic separator, an additional controllable and measurable quantity of air can be injected to give constant flow through the cyclone. Used to analyse the size distribution of dusts dispersed in a gas stream. If such dusts are separated and subsequently analysed, then there is an error introduced by possible aggregations occurring in the dust heap. This is avoided if the analysis or separation is carried out with the dust still "live" or suspended, as is the case in the method claimed.

Title: Locking mechanism for cutout switch - has two series of pivoted levers, one in housing and other in rotary insert
Inventor: MERKLE PAUL
IPC: E05B29/00
Filed: 1975-03-15
Abstract: The locking mechanism, for a protective cutout switch, has two series of pivoted levers as locking members. The first series is located inside the lock's rotary insert, and the second series is located in the lock's housing. When a given angle is exceeded these locking levers move into the region occupied by the other main parts of the lock. The mechanism has laterally pivoted locking levers, whose ends move through circles, instead of the radial and linearly moving locking members of a previous arrangement, and compared to the normal cylinder lock this mechanism replaces housing locking by pivot locking.

Title: Bituminous road surface anchorage on firm base - has intermediate layer of ribbed patterned plastic mortar
Inventor: PANKUWEIT HARTMUR
IPC: E01C7/32
Filed: 1975-04-08
Abstract: The process is designed to promote firm anchorage of road surfaces constructed on site, exp. where these are made of a bituminous compound on a firm base. It is suitable for initial road surfacing, and for resurfacing after wear. Use is made of an adhesive or anchoring layer above the metal, concrete or other hard base (1). Knobs and/or ribs of mortar are formed on the base, firmly cemented to it, and these are then covered with road-surfacing material in the usual way. The knobs or ribs are formed in regular or irregular pattern, by laying a perforated (4) matrix plate on the base and pressing pasty plastic mortar into the holes, then withdrawing the plate when the structure holes, then withdrawing the plate when the structure has sufficiently hardened. A protective coating to resist salt, corrosion and thaw damage may be provided.

Title: Cotexturised bi-component bundle yarn - having structured change zones between left and right windings of cladding yarn round the core yarn
Inventor: LYHOLM IB
IPC: D02G1/02
Filed: 1975-12-20
Abstract: In the mfr. of a cotexturised bundle yarn composed of two yarn components of the same or different polymers (such as polyamide 66 or polyester) each component is a bundle yarn and one is wound round the other as a core with change zones between left and right windings. The wound component is 20-50% longer than the core component. The change zones are incorporated at a rate of 300-700 per metre, with more than 25% of the change zones so constructed that there is an open yarn structure where the core is more or less visible. The wound component in the remaining change zones lies closely packed round the core. Between the change zones, the wound yarn component is tightly wound, the sum of the wound zones representing 25-75% of the total yarn length. The process allows the manufacture of a yarn with a wool character and handle, with a mixture of colours to give special effects when worked into a fabric.

Title: Key holder strap for swimmer - has key swinging inside protective slot, and trapped by wrist curvature
Inventor: STAUDE HEINZ
IPC: A44C5/00
Filed: 1976-01-29
Abstract: The strap may be worn on the arm or leg of a swimmer in e.g. a swimming bath so that a key may be carried. It has a conventional bucklet (2) at one end to engage one of a set of holes at the end, and the centre threse extende outwards two tongues (7), each with a hole (9) through the tip for insertion of a pin (10) acting as a pivot for the key (11). At the region of these tongues is a slotted pocket inside the strap, open towards the pivot side of the strap, so that the key can be swung inwards inside the slot thus avoiding possible injury to the wearer. When the strap is attached, its curvature traps the key inside so that it cannot swing out again.

Title: Control circuit for interrogation of signal sources - has counting stages checked for simultaneous interrogation signals and disconnected at signal presence
Inventor: PLAUE HELMUT
IPC: H04Q3/54
Filed: 1976-03-31
Abstract: The circuit consists of counting stages connected into a ring counter. Their outputs are connected to the signal sources to be interrogated and also to the inputs of a fault detector which finds whether one or two or more ring counter outputs carry an interrogation signal. When two or more signals are present, a fault is signalled. Outputs of at least two adjacent counting stages of the ring counter are connected to at least one logic element. When two or more interrogation signals are present, at least one switch is operated. Counting stages which have a lower order number than that which causes the operation of one or more switches are disconnected, and omitted during subsequent counting cycles.
