Title: Temp. probe for mould-spool windings with conductor-profiles - has close-fitting silicone-rubber surround for conductor-bundle and receiving semiconductor-bead
IPC: H02K11/00
Filed: 1974-08-20
Abstract: The temp. probe arrangement is intended for windings of electrical machines in which a semiconductor-probe is embedded into an insulating-body and leads to this probe consist of highly flexible wire-strands with silicone-rubber insulation. The insulating-body gives a close-fitting enclosure to the conductor-body of the spool, without leaving any air gaps and empty spaces, and receives the non-insulated semiconductor-bead of the probe. The insulating-body is made of cold-vulcanised silicone-rubber compsn. with condensation-crosslinking agent. In this way, incorporation of the temp. probe into spool-windings with profiled conductors is made independent of the dimensions of the spool and interruption of the high-tension insulation is avoided.

Title: Gaming board divided into polygonal cells - identical playing paths for more than two players
IPC: A63F3/02
Filed: 1974-12-12
Abstract: The overall shape of the gaming board is circular, its diameter being a multiple of the polygonal shapes used, an odd number permitting one shape to be in the middle. The polygon chosen depends on the number of players, this preferably being odd. A hexagon allows three players to participate. The playing paths (1, 3, 5), and the areas marked out by them, are all identical and start from the centre to pass in a generally spiral shape to the board outer perimeter. Additional paths (0, 2, 6) may be marked out, these connecting the main paths in any way, providing the playing areas remain identical.

Title: Vertical lime kiln operation - using fuel oil emulsified with water
IPC: F23K5/12
Filed: 1976-03-11
Abstract: Water emulsified inthe fuel oil is used to produce fuel for heating, the emulsion typically containing 10-15% by weight of water. The water can be heated before adding to the oil, and it can be in the form of steam when introduced into it. The emulsion can particularly be used in limekilns of the vertical type, and the water can be added to the fuel oil by gravity.

Title: Insulating external wall facing of rigid foam panels - with rendered surface can be used for thick insulation without cracking
IPC: E04B1/76
Filed: 1976-03-24
Abstract: A method for making insulating, plastered or rendered external walling consists of using grooved rigid foam panels and plastics-modified mortar. The rigid foam panels still possess a residual creep of at least 1 mm per metre, and a mortar having a plastics content of less than 5 (2-3)% is used. The prepared rigid foam panels are polystyrene panels which have been stored for less than 3 months. The mortar may contain an embedded glass fabric. In particular for relatively thick wall insulation, up to thickness of 100 mm, as demanded in modern buildings to keep heating costs to a minimum. The arrangement enables the difficulties caused by thermal expansion and warping and shrinkage of the panels to be overcome, without necessitating excessively long prior to storage times, for example of up to 6 months.

Title: Mechanical handling device for foundries - can move in a variety of directions with reduced power
Inventor: CHABRY GILBERT
IPC: B22D29/00
Filed: 1976-07-12
Abstract: A mechanical handling device has a manipulating arm and a pair of grips and means for moving the arm in a determined and modifiable volume.
