Title: Treating harmful residues from gas-washing plant - by absorbing onto a porous temp-resistant granulate before incineration then granulate is washed for reuse
Inventor: HOELTER HEINZ
IPC: F23G7/04
Filed: 1978-04-12
Abstract: Combustion of encrustations and deposits in gas washing plants is as follows: The concd. wash liquor contg. the toxic substances is fed to an absorbent, temp.-resistant, carrier material, esp. perlite, and is then combusted at a temp not high enough to harm the perlite but sufficiently high to burn the toxic substances such as phenol and formaldehyde. After the combustion process, the porous substance, esp. perlite, together with the deposited and absorbed liquor is placed in a liquid-solid separation device, e.g. centrifuge or drum vacuum filter and washed out. The remaining solids are then available for reuse in the process.

Patent DE-2836768-A1 (DE)
Inventor: CREDE HELFRIED DIPL PHYS
IPC: F25B27/02
Filed: 1978-08-23
Abstract: The plant comprising a heat pump and used to collect the heat for heating from surrounding heat sources such as outdoor air, is provided with a water tank (5) which is in heat exchange relationship on one hand with the surrounding heat source and, on the other hand, with the coolant circuit of the heat pump through a coolant evaporator (6). By drawing heat from the water tank (5) and introducing that heat into the coolant circuit, the water tank (5) is always kept at a low temperature close to 0`C so that there is almost permanently a heat transfer from the surrounding heat sources towards the water tank (5). To reduce the size of the water tank (5), a coolant evaporator (7) is provided in contact with the outdoor air and it evaporates part of the coolant which is variable according to the outdoor temperature. During hot periods the outdoor evaporator (7) may be used to heat the water tank which is possibly frozen by introducing into the water tank (5) the heat coming from the outdoors air through an additional liquifier (9) mounted into the water tank (5).

Title: Supply magazine for components for printed circuit boards - uses coiled belt with components attached adhesively using strip or plastics foam material
Inventor: ZIELKE ALFRED
IPC: B65D73/02
Filed: 1979-03-06
Abstract: The mounting for electrical components such as relays on printed circuit boards, by means of a machine, uses a belt to carry the components, wound into a spiral to form a magazine. They can be adhesively attached by using, e.g. a plastics foam layer. In another method, adhesive coated strip is used to attach the components. Whichever method is used, a layer of e.g. waxed paper can be used on the other side of the band to prevent sticking. In a further method, wires are used, parallel with the belt to support the components. In all cases the components are attached by the faces which are free from connection wires. The strap itself may be of a resilient material such as plastics foam. It can be wound onto a spool having side flanges. The connection wires can face outwards.

Title: Reactor core support - on thermal shield through spring loaded plunger on easily detached slider
Inventor: ELTER CLAUS DR ING
IPC: G21C5/10
Filed: 1979-05-29
Abstract: Core of a nuclear reactor is supported against a structural component nearby, specially a thermal shield, by an anchor plate welded to the latter which carries slidways. An intermediate member can slide on the slideways and can be locked in position by eccentric cams. A cylinder, loaded by disc springs, on the intermediate member, contacts the core by a barrel-shaped cemented carbide insert to allow a core displacement at right angles to the spring thrust. Such a support can be easily assembled and dismantled. It permits relative axial movements between core and shield and is simple in design so that it can be produced at low cost.

Title: Drive for wheeled land vehicles - has rotating masses successively accelerated and decelerated to produce resultant forward force
Inventor: GROSSMANN FRANZ-KARL DIPL ING
IPC: F03G3/08
Filed: 1979-07-13
Abstract: A bogie (3) carries an electric motor (1,2). When the rotor (1) is accelerated there is a reaction torque (E) on the stator. This produces forces (a,b) on the front and rear axles which have components (d,f) in the forward direction. A second motor mounted on the underside of the bogie produces additional forces in the same direction, if it is decelerated as the first motor is accelerated. The action can be made continuous if the motors are rotated about the horizontal axis, while being successively accelerated and decelerated. A motor is always above the axis, while being accelerated, and below it during deceleration.
