Title: Integrated circuit perforated carrier film - has opening for components bounded by perforated sides and by crosspieces
Inventor: ROSSTEUTSCHER GERHARD
IPC: H01L21/60
Filed: 1979-04-02
Abstract: Handling of integrated circuits is mechanised by inserting them into opening of a perforated carrier film which can be precisely pitched during the insertion into the printed circuit board. The two sides of the carrier film (I) are linked by ross-bars (3) which separate the openings (2). In the course of insertion of the integrated circuit the film is soldered to the board by a punch and the film is cut off. In another version of the design the cross-bars (3) are provided with apertures set in precise relationship to the film perforations (II). The openings are engaged by projections of the integrated circuit housing from which the the circuit element is ejected for the assembly and the film is taken up on a spool.

Title: Time switch with two time periods and power settings - has first full power triac circuit followed by second period half power thyristor setting
IPC: H03K17/292
Filed: 1979-08-16
Abstract: The time switch control is for a.c. powered equipment with one or more switches, e.g. automatic control of lights on a staircase. The appliance (lamp 1) is controlled for two time periods, the first at full power and the second for safety purposes at reduced power and brightness. The primary circuit is full wave through a triac (6) controlled by the first time control circuit (8) after the main switch (22) has been operated. After expiry of the first time period, the triac is switched off and the second time period started by connecting the control lead (18) of the half wave thyristor (19) to a time control output (13) and switching it on (thyristor 19). A second circuit is given using a third time period and employing multivibrators and flip-flops.

Title: Fluidised bed cooler for hot solid particles - has by=pass to compensate air or product temperature variations
Inventor: CURTIUS FRIEDRICH
IPC: B01J8/36
Filed: 1979-11-23
Abstract: A bed of solid particles is continuously fluidised and cooled by atmospheric air during transit in a channel along a path between an inlet and an outlet which are themselves closely adjacent. To keep the outlet temp. largely constant even when that of the cooling atmos. or of the incoming particles is varying, at least some of the particles are by-passed, pref. at a position near the inlet and then returned to the main stream of particles nearer the outlet. The by-pass may be a weir or a pivoting feeder. The unit can be smaller than known beds which have to accommodate wide temp. variations, and avoid the need for preliminary cooling of the incoming air.

Title: Measuring plastics coating thickness on printed cardboard - by using three different infrared wavelengths
Inventor: MERCER PETER G
IPC: G01B11/06
Filed: 1980-04-17
Abstract: A method of measuring the thickness (or weight per unit area) of a coating is intended esp for measuring the thickness of plastics foil applied onto printed or unprinted cardboard; UV radiation of two different wavelengths is used, one of which is absorbed and the other not absorbed by the coating and the substrate. In addition, a third, auxiliary wavelength is used, which is absorbed only by the substrates; this is employed to determine that proportion of the absorption of the first wavelength which is attributable to the substrate material; from this result an auxiliary signal is produced, from which an auxiliary value is computed; this auxiliary value is associated with the first (absorbed)wavelength and is at least approximately equal to a measuring signal which would be obtained if the substrate were not coated and the first wavelength were used. From the above the proportion of the first measuring signal attributable to the coating material is determined, from the difference between the auxiliary value and the first measuring signal. More specifically, the auxiliary value is calculated by multiplying the auxiliary signal by a factor which is proportional to the absorption coefficient of the substrate at the first wavelength divided by the absorption coefficient at the auxiliary wavelength. Used partic for measuring the thickness of plastics foil on a cardboard box etc where printer's ink has been used to produce a legend method enables the thickness of the coating to be measured with adequate accuracy.
Patent DE-3015971-A1 (DE)
Title: Movement direction discriminator for body with magnetic markers - has magnetic latch giving defined rest sensor position and sensor delivering signal indicating direction of previous movement
Inventor: FRANKE WOLFGANG
IPC: G01P13/04
Filed: 1980-04-25
Abstract: An arrangement for discriminating between motion of a body to the right or left involves two marker types applied alternately and at defined intervals to the body and scanned by fixed sensors (15,16) separated by a different interval. The sensors respond to one or other marking and provide signals to a direction evaluation circuit. After each movement of the body the sensors are in a defined position w.r.t. it. This ensures that the first sensor signal for each movement gives an unambiguous indication of the direction. The markings are south (3,5,7,9,11,13) and north (2,4,6,8,10,12,14) poles. A latching device (18), consisting of one or more magnets, holds the body with a defined force at intervals corresp. to that between two adjacent markers or to a whole number multiple of it.

Title: Two-pole dynamoelectric machine - has rotor with lamination groups holding conductors with steps controlling clearances
Inventor: LACKEY DALE FRANKLIN
IPC: H02K1/26
Filed: 1980-06-14
Abstract: Reduced vibrations of the two-pole rotor of the dynamoelectric machine is achieved by separating groups of laminations with the object of lowering their thermally-induced interaction. The spacing of the groups of laminations is controlled by the axial clearances using aluminium casting of bars in the slots of the laminations forming beads outside each group of laminations. When extruded, copper bars form the winding then the groups of laminations are secured by dipping in an epoxy or lacquer bath. The lamination groups (12) are carried by the shaft and feature conductor bars (16) of aluminium which form the spacers (18). The end rings (32) and fan blades (34) are cast at the same time as the conductors.
