Title: Heat transfer, flame resistant laminated board - has top and bottom layer impregnated with soln. of hydrate, phosphate or sulphate crystals contg. water of crystallisation
Inventor: LOHRUM GEB BOEHMER
IPC: E04B1/94
Filed: 1980-02-09
Abstract: In a multilayer, flame resistant, heat transfer reducing laminated board with a bottom and top layer of pressed mineral-, clay-, aluminium oxide-, glass-, ceramic-, graphite-, basalt-, vegetable- or animal fibres or wool thereof, both the top and bottom layer are impregnated with a liq. to viscous soln. of hydrate-, sulphate- or phosphate crystals contg. water of crystallisation e.g. potassium aluminium sulphate, disodium (ortho)phosphate, trisodium phosphate, tetrametaphosphate, other orthophosphates contg. water of crystallisation, monosodium phosphate or "marble white chalk O". The soln. is prepd. by heating and/or addition of water. On exposure to high temps. e.g. 1000 deg.C, water of crystallisation separates off, cooling the board and reducing heat transfer. On longer exposure to elevated temps., a recrystallisation of the water of crystallisation occurs with simultaneous high heat energy formation and a desensifying of the surfaces and the board. The desensifying brings about heat storage with delayed release. During the delay, heat transfer is interrupted.

Title: Single phase induction motor with inherent self starting - employs auxiliary winding acting as choke with flux at defined angle to main flux
Inventor: SCHOTTEN HENNO DIPL ING
IPC: H02K17/30
Filed: 1980-06-19
Abstract: An auxiliary winding (Hi) is wound round the stator yoke,passing round the core back and along the bottom of stator slots on the axis of the main pole flux (phi2). These coils are wound in a similar sense such that most of the flux generated (phi1') passes through the magnetic material of the rotor. The rest leaks round the core back. The auxiliary winding in effect acts as a choke. The main and auxiliary winding fluxes thus stand in a defined phase angle to each other and thereby produce the required torque on the rotor. No starting capacitors or speed operated switches are required.

Title: Elliptical lamp reflector with IR suppression - has filter and reflector coatings to deflect infrared away from main beam and out of reflector rear
Inventor: FRANKL SANDOR
IPC: F21V9/04
Filed: 1980-11-24
Abstract: Industrially manufactured elliptical reflectors reduce the infra-red component of the output light beam. The reflectors are a combination of glass elliptical reflector (1) with the light source at the focus point (4) and a front reflector (6) with an output beam window (7). The elliptical focussing reflector (1) has an interference filter layer coating (5) which is transparent to infra-red, and some red light, (10) as emitted by the light source (4). The coating (5) permits light with a wavelength greater than 780nm to pass through. The elliptical reflector (1) is fronted by another reflector (2) which has a central output window (7). The light cone (8,9,10) from the light source (4) is either reflected off the side of the elliptical reflector (8,11) through the output window (7), reflected by the front mirror (2) for further reflection (9,16) by the elliptical reflector (1) through the front window (7). The front reflector (2) reflects all wavelengths so that the infra-red (15) can be filtered out by the elliptical reflector (1). The output window (7) also has a filter coating (3) to reflect the infra-red (12,13).

IPC: E21C27/32
Filed: 1981-02-21
Abstract: The invention relates to a baseplate plough, the plough body (1) of which has in an asymmetric arrangement at each of its two ends a swivel segment (11) which is pivotably guided in a segment guide (12), carries a bottom-blade group (14) and is supported in the working position against an adjustable stop (15). The swivel segments (11) lie under blade groups (24, 25) of the plough body (1). In order to ensure that the swivel segment (11) lying in each case in the front in the direction of travel is held in contact with the stop (15) in its working position, the two swivel segments are coupled via an articulated rod coupling (18) and a sliding piece (21) guided in a sliding guide (22) of the plough body. In front of the sliding guide (22), the plough body has a vertical guide (27) in which a blade holder (28) consisting of a blade clapper is guided and held in such a way that it can be extended upwards in order to be able to adapt the cutting height of the plough to varying seam thicknesses. In addition, attachable blade blocks (39) can be put onto the plough body (1). The attachable blade blocks (39) extend the vertical guide (27) of the plough body upwards. The invention provides a plough which, at a low basic height, can be set to large cutting heights when required and in which reliable setting of the bottom-blade groups in the working position can be achieved in a favourable spatial arrangement of the functional parts. <IMAGE>
