Title: Multi-terminal connector reflow soldering unit - has frame holding one section and spring-biased needles pressing leads
Inventor: BAHNSEN HEINER
IPC: H05K3/34
Filed: 1979-03-14
Abstract: Improved reflow soldingof multi-terminal connectors is ensured by a clamping frame for holding one section featuring solder areas. A clamp (3) with spring-biased needles (4) presses the second section (5) so that the leads (8) for soldering are forced against the corresp. spots of the first part (2). The hot air jets (6) are set at an angle of 10 degrees from the horizontal and are fitted on both sides of the soldering spots. The temp. of the hot jet is controlled by a thermocouple (7) and during the soldering the needles force the leads (8) into the molten solder. The precise jet temp. is set with air flowing through a heating spiral.

Title: Multiple network earth compensating system - has earthing coils connected by voltage monitoring circuits and selector to central control unit
Inventor: WEBER WALTER
IPC: H02H9/08
Filed: 1979-03-22
Abstract: The earth connection compensating system for more than one mains supply, has the variable inductance earthing coils of the high voltage transformers of, e. g. two supplies, connected to the coils of respective controllers. These are in turn connected to a main control unit located at a central control print. This has further input/output connections for switching units connected to opposite sides of the two sets of earth ing coils. Each earthing coil is also connected to a voltage monitoring circuit to give the instantaneous value of the switching voltage. Their outputs are connected by a selector stage to the input of the main control unit, and there is a return path for each monitor from the main control unit. The unit then compensates the two supplies until a balanced condition is reached.

Title: Preheating and partial calcining plant for granular or bulk material - has ring shaped suction duct and ring baffle below which is braking plate
Inventor: POSPISIL JAROSLAV DIPL ING
IPC: B01J6/00
Filed: 1979-04-27
Abstract: The plant consists of a vertical ring shaft contg. a hollow, ring-shaped suction duct removing heating ases and dividing the charged material into two ring streams flowing through a calcining shaft and then over a ring baffle. Below the ring baffle is a braking plate, which is also ring-shaped and has a central hole for heating gases flowing upwards to the suction duct. Heating gases also travel upwards on the periphery of the braking plate in counter current to a descending stream of the charged material; and the braking plate is covered by plates reciprocating horizontally to drive the material both down the bore and over the edges of the braking plate. The plant can be used for heating material before the latter enter a rotary drum sintering furnace, and reduces both the capital- and operating- costs of the plant expressed per tonne of material produced.
Patent DE-2918740-A1 (DE)
Inventor: AEPPLI KURT
IPC: G01B7/12
Filed: 1979-05-09
Abstract: The process and the device can be used for yarn cleaners, which are known per se, on winding machines and the like. The element determining the yarn velocity, in particular the grooved drum (3), is provided with a pulse generator which transmits velocity-proportional pulses to a processor (30). The digitalised measurement signal from the measurement head (20) is also supplied to the processor (30) and the magnitude of this measurement signal is ascertained with each of the impulses triggered by the grooved drum (3). The yarn cross-section is thereby always determined at equal intervals and the yarn cleaner operates independent of velocity. In addition on one hand the wound spun yarn length can be determined simply by adding up the pulses, on the other hand, by the point-by-point sampling of the measurement signal at constant intervals, the yarn travel can also be monitored independent of velocity without additional evaluation elements needing to be provided. <IMAGE>

Title: Flash evaporator for desalination - having central feed via overflow weir which causes liquor to run back over inlet duct into collection channels (OE 15.5.80)
Inventor: BOBIK MICHAEL DR
IPC: C02F1/06
Filed: 1980-01-25
Abstract: Multistage flash evaporator has a condenser pipe running along the top. The feed liquid is introduced into a rectangular channel along the base. This has a pair of rectangular weirs above it over which the liq. flows, down onto the upper surface of the closed channel. Some evapon. occurs and the remainder of the liq. runs into collection channels on either side. The liq. runs diagonally into the central channel of the next effect. In this way flow from effect to effect is achieved. Used esp. for desalination evaporators. Avoids the problem of flooding and level control which occurs with some evaporators and thus allows more uniform evapn.

Title: Evaluating thermal consumption of individual apartments - utilises heating medium and room temp. measurements using computer
Inventor: JAEGER WALTER ING GRAD
IPC: G01K17/06
Filed: 1980-03-29
Abstract: The arrangement is used for measurement and evaluation of the thermal consumption of individual consumers in heated buildings enables accurate measurement and power consumption evaluation taking account of different thermodynamic conditions. They enable detection of fraud and allowance for heat gains other than from the heating system, e.g. from solar radiation and body heat. The thermal energy input to each flat is determined by computer from the sum of the power transferred from the individual heaters. The flow of heat is measured between adjacent sensors and evaluated by computer. The thermal consumption of each consumer up to a certain time is derived from these measurements which involve feed and return temp. measurements on the heating medium and room temp. measurement. The evaluations take account of the flat dividing wall heat conduction properties.

These tubes (91) pass through an annular cooling jacket (7) which is traversed by air or water. The assembly is held in an aluminium casing (1) which assists heat transfer between the different components.

Title: Purified air feed esp. into automobile - heats air before filter to improve sorption and catalytic effects
Inventor: HOELTER HEINZ ING GRAD
IPC: B60H3/06
Filed: 1980-07-26
Abstract: A method of purifying air to be fed into a protected working zone or automobile cabin utilizes a filter consisting of a permeable support on/in which chemical absorption materials and/or catalysts are laid. The incoming air is entirely or partly heated before it reaches the filters. When the appts. is in use, the normal fresh air inlet ducts of an automobile are closed and the ventilator fan is converted for use as a pure circulating fan recycling the entire air content of the vehicle. In addn., a separate ventilator fan draws in air and expels it at above-atmospheric pressure into the circuit via the chemical absorption filter. A corresponding quantity of air escapes from the circuit to atmosphere. In particular for automobiles in traffic jams or smog conditions as a substitute for conventional ventilation. By heating the air before it reaches the chemical absorption filter, moisture in the air is prevented from precipitating. Precipitation of moisture has a very adverse effect upon the effect of chemical absorption agents and catalysts. Thus the efficiency of the plant is greatly improved.
