Patent DE-3004665-A1 (DE)
Title: Pushbutton lever arm electrical switch - with switch and contact arm tongue and groove supported by central pillar and retained by spring
Inventor: MARQUARDT ERICH ING GRAD
IPC: H01H13/28
Filed: 1980-02-08
Abstract: The pushbutton lever arm electrical switch mechanism is designed to minimise construction costs. The lever arm (2) and contact arm (3) units are tongued to fit into side slits in the central support pillar (4) of the switch which is also one contact unit reaching through the base to a terminal. Fitting the tongues of the lever and contact arms into the side slits also serves to limit the extent of hinging possible by the two assemblies. The lever and contact arm are held in position on the central pillar (4) by a tension spring (5). This can be dropped into the casing as a completed unit.

Title: Mangle air flow - has closed loop air path with heat exchanger to economise on energy
Inventor: STICHNOTH OTTO
IPC: D06C15/04
Filed: 1980-11-25
Abstract: The mixt. of air and steam is drawn out of the rollers by suction, individually or in gps., and passed over each roller for extraction to flow to the preceding roller in the direction of the laundry passing through the mangle. The air drawn out from the first roller is used at least partially as recirculating air returned to the last roller. The system uses the energy consumption more effectively and economically. The water absorption effect by the air is also improved. Specifically the air from the first roller, in the direction of laundry movement, is at least partially dehydrated before recirculation to the last roller. The air from the rollers passes in a closed loop in the mangle, which includes a heat exchanger outside the mangle for dehydration, and further heating for return to the rollers. Part of the air from the first roller is evacuated according to its moisture content to determine how much goes out as exhaust and how much is recirculated.
Patent DE-3102595-A1 (DE)
Title: Nitride hardening method using high-temperature electrolysis
Inventor: SATOH SHINZOH
IPC: C25D11/00
Filed: 1981-01-27
Abstract: In the method, the workpieces to be nitrided are immersed in a molten cyanide bath containing low-grade or low-quality titanium and/or zirconium oxides in hot, dispersed form as a catalyst and kept in a temperature range of 760-850 DEG C. A direct current having a density of 10-100 A/dm<2> is passed through the cyanide bath with the workpieces being used as anodes. In this way, extremely deep nitrided layers with high hardness are obtained on the workpiece surfaces within a very short operating time because of the rapid nitriding reaction at such a high treatment temperature. Despite the treatment temperature being so high, the deformation of the nitrided workpieces is very small. In addition, the method can be applied to materials such as titanium, high-alloy steels, cast iron, etc. which are regarded as difficult to nitride by standard procedures.

Title: Ventilation device for rooms with two separate flow paths for aeration and deaeration
Inventor: KUCHARCZYK ECKHARD
IPC: F28D9/00
Filed: 1981-07-22
Abstract: A ventilation device for rooms with two separate flow paths (32 and 33) for simultaneous aeration and deaeration is designed in such a manner that it extracts from the outgoing-air flow AB the heat energy inherent therein and transfers it to the outside-air flow AU. In this case, it makes possible, with low technical outlay, a considerably improved multiple use of the enthalpy of the outgoing-air flow AB leaving the room and correspondingly a greater heat recovery. At the same time, however, it is ensured that the radial blower (13) which serves for conveying air in both flow paths (32 and 33) has practically corresponding outputs for both flow paths (32 and 33). It is important in this case that the longitudinal partition (37) assigned to the air outlet (8) and the air passage grating (10) is connected firmly to the far end of the heat exchanger (26) from the radial blower (13) and has an end section (37) which is bent or curved towards the air outlet (8) and reaches behind the latter, and that the holding plate (20) for the stator of the radial blower (13) and the end adjacent to it of the heat exchanger (26) are connected via insertion couplings which extend perpendicularly to the longitudinal direction of the plate and in each case consist of an insertion bolt and an insertion hole. <IMAGE>

Title: Method and device for individual cooling of rooms of a building
Inventor: BLAHA EDUARD ING
IPC: F24F1/01
Filed: 1981-11-11
Abstract: In a cooling system, which works with a variable cooling air quantity, for the rooms of a building, the primary air is cooled to temperatures which lie at least 10 DEG  lower than the room air temperature of the room (15) to be cooled. This cold primary air is mixed in an induction device (1) with secondary air drawn in from the room (15), before the mixed air is blown out into the room (15) as cooled incoming air. The mixing of the primary air and of the room air before outlet into the room (15) makes possible the use of lower primary air temperatures; it follows from this that, for the same heat removal, smaller primary air quantities are necessary than previously, as a result of which the ventilation installation can be designed smaller and thus the space requirement and outlay therefor as well as the energy requirement can be reduced. Furthermore, the drawing-in of the inducted room air in an induction device (1) ensures that the mixing ratio between primary and secondary air remains approximately constant for all the variable primary air quantities which depend on the cooling capacity required. <IMAGE>
