Title: Swivel fitment for foldable kitchen bread slicers - has space saving counterbalance formed by tensile spring
Inventor: KAISER GUSTAV
IPC: A47B77/12
Filed: 1976-09-18
Abstract: The swivel fitment for foldaway bread slicers and other kitchen utensils comprises two lateral swivel brackets (5) which are attached to the base plate (4) on which is mounted the utensil. At least one of these brackets is provided with an extension (18) to which is connected a tensile spring (17) which acts as a counter balance for the weight of the utensil. This tensile spring (17) is connected at the other end to the longitudinal support (7) which is connected at its end to the swivel bracket and can be moved in and out of the cupboard housing along guide rails. When the base plate (4) is in the swivelled-in closed position the bracket extension (18) does not protrude beyond the upper edge of the longitudinal support (7). The tensile spring (17) is bent over a peg (19) attached to the longitudinal support (7) when the base plate (4) is in both the closed and open position.

Title: Impeller for tank agitation - having blades bent to give two angles of inclination to shaft axis over a radial distance
Inventor: ADLHOCH HANS JOACHIM DIPL ING
IPC: B01F7/00
Filed: 1976-09-28
Abstract: Impeller is for mixing and homogenising materials in a vessel or column one of which must be in a liquid or mobile phase. It uses a motor driven shaft from which extend flat blades inclined at an angle to the axis of the shaft. Each flight has surfaces which form two continuously defined angles of inclination to the shaft axis over a certain radial distance from the shaft. Each blade is formed from a flat rectangular plate the root of which is attached to the shaft at an angle. The blade is then bent, curved or formed to form a second angle of inclination, different from the first but extending from the root. The blades thus form inclined surfaces extending from the shaft.

Title: Window or door metal profiles heat insulating connection - using plastic batten with groove, and grooves between acute angled stem protuberances
Inventor: SUPPUS HEINZ F W
IPC: E06B3/263
Filed: 1976-12-04
Abstract: Heat-insulating connection between two metal profile pieces, in doors, windows or other elements, is effected by a plastic batten engaged by a stem on one of the pieces with a number of lengthways protuberances. The batten (5) is more than 0.8 mm thick, and incorporates a smooth-sided groove (15) to hold the stem (6, 7), 0.3-0.8 mm less in width (13) than the thickness of the stem including protuberances (8). These are acute-angled, and have intervening symmetrically shaped lengthways grooves (9). The ratio of the interval (A) between groove side (16) and adjacent open batten edge (17) to groove depth (T) is at least 1:1.5. This can absorb considerable tension and transverse forces arising from bending stress, facilitating production of large-area windows and doors with insulating effect from both frame profile pieces.

Title: Foundry cores hardened by mixt. of catalyst and air - fed via programmed valves eliminating danger of explosion
Inventor: MICHEL HORST-WERNER ING GRAD
IPC: B22C9/12
Filed: 1977-02-05
Abstract: Foundry cores are made where a catalyst is fed via a doser into a mixing chamber(MK) supplied with compressed air via a resulting valve(RV). The mixt. is then used to gas a core, followed by only the air to blow the gas out of the core box. After passing through valve(RV), the air enters on electrically heated storage tank(HL) using a pipe (a) to supply mixer(MK). During the pauses between gassing, tank(HL) is blocked, and cold compressed air is fed into pipe(a) for blowing the gas out of the core box. Pref. pipe(a) contains two valves(1,2) and mixer(MK) is followed by an outlet valve. Between valve(1,2) is a junction with a nozzle for the cold air fed via a programmed valve and used in conjunction with a control valve on the catalyst doser. The metal mixer(MK) is pref. prevented from overheating; and the catalyst is cooled via cold air before entering mixer(MK). Very short gassing times can be used without danger of an explosion.

Title: Clothes line assembly - pivots on ceiling mountings to give upper and lower positions to free room space
Inventor: SCHUBERT EGON P
IPC: D06F57/12
Filed: 1978-03-08
Abstract: The construction of a washing line structure for mounting to the ceiling of the wash room in one- or two-family houses, occupies a space of 2500 + 1000mm, supporting 37m of clothes line. An operating rod allows the height to be adjusted so that the distance from the ceiling to the lower edge of the assembly is reduced from 400mm to 200mm. The design allows the room space to be fully utilised for recreation, without the clothes line structure inhibiting movement. The side frames of the assembly are joined by a connecting rod, and one frame has an eyelet. The operating rod is inserted in the eyelet to swing the side frames to one side, pivoting from the ceiling. This allows the assembly to be locked in the upper position, and hang in the lower position. The operating rod is suspended from the mounting, when not in use, so that it does not disturb the use of the room space but is available when needed.
