Title: Hot and cold water mixing valve - has valve member movable between two opposite seats for heater bypass ducts
Inventor: MOSSBACH WILHELM
IPC: F16K11/044
Filed: 1976-03-19
Abstract: The mixing valve for hot and cold water has a main inlet (30) leading to a chamber (26), where a valve member is movable between two axially opposite seats (15, 20) respectively leading to a main outlet (17) and to a bypass duct (32) connectable to the inlet of a bypass heater (33). The main outlet has a mixing junction (34, 35) connectable to the outlet of the heater. If the valve member closes the one seat (15) the supply coming through the main inlet passes wholly through the heater before entering the main outlet. As the valve member is moved towards the other seat a progressively greater part of the supply passes directly to the main outlet.

Title: Three speaker loudspeaker cabinet - has HF and mid-frequency units mounted on common base plate with terminal block
Inventor: HENNEL HANS G
IPC: H04R1/02
Filed: 1976-06-18
Abstract: The loudspeaker lay-out for the simplified construction of loudspeaker cabinets is based on a common mounting plate for two of the three loudspeaker units in the usual three-unit arrangement. The high-frequency unit and the mid-frequency unit are constructed on a common base plate with fixing holes in each corner. Alternatively, each speaker may have a separate mounting plate but of similar dimensions, esp. height to the other. In this case, the speakers are then fixed to a commn baffle board for mounting in the cabinet. The common mounting for the high- and mid-frequency units provides improved physical and acoustic characteristics and simplifies assembly when mounting them in conjuction with a low-frequency drive unit in the same cabinet.

Abstract: Material, used in the form of a continuous coating or plates or stones, is a hydraulically hardening compsn. contg. 10-30 wt.% of ground and granulated blast furnace slag as a binder, and the balance of a particulate filler (crystalline blast furnace slag, stone flour, gravel, broken stone with clayey inclusives etc). The blast furnace slag is ground so that 2-30 wt.% of the particles are smaller than 0.075 mm. A part of the blast furnace slag can be replaced by a cupola furnace slag (5-15 wt.%). The compsn. may additionally contain 0.5-5 wt.% of lime, 0.5-10. wt.% of a porous stone, 1-10 wt.% of an alkaline earth metal sulphate, and/or 0.1-5. wt.% of an alkali(ne earth) metal chloride. Industrial wastes are utilized and the resulting material is not inferior to the known, more expensive compsns. The presence of the very small fraction (0.075 mm). of the ground slag ensures strong binding.

Title: Molten iron contg. magnesium fed into moulds - by pressurised inert gas contg. oxygen to prevent magnesium vapour blocking gas valves
Inventor: DOETSCH ERWIN DIPL ING DR ING
IPC: B22D39/06
Filed: 1976-10-12
Abstract: Molten cast iron, which has been treated with magnesium to mfr. nodular cast iron, is fed in dosed amts. for casting by a pressurised inert gas in a casting appts.; and the inert gas contains a specific amt. of oxygen, pref. 0.5-5 wt.%. Pref. the addn. of O2 depends on the operating stage of the furnace; and the inert gas and O2 are mixed in a pressure reservoir, to which O2 is added via a choke valve adjusted by a servomotor according to the rate of evapn. of the Mg. Inert gas, e.g. N2, is used to drive molten iron into a mould, but the Mg vapour from the treated iron enters the N2 and blocks the valves or pipes in the gas circuit by deposition. The deposits of Mg can also cause an explosion. The O2 added to the gas oxidises the Mg. vapour so MgO enters the slag and does not reach the gas circuit.

Title: Fracture monitor for tube carrying fluid - has spring loaded pistons and reed switches generating signal on leakage
Inventor: SEULEN GERHARD WALTER PROF DR
IPC: F17D5/06
Filed: 1976-11-10
Abstract: The fracture monitoring system is used for pipelines and hoses carrying liquids or gases in opposite directions e.g. in high pressure hydraulic systems in cranes, excavators and scoop loaders. At either end of the tube or hose section (1) is fitted a sliding hollow piston (10, 11) in a tubular element (2, 3).

Title: Random yarn dyeing process - has a tubular yarn pattern continuously advanced through a jet assembly applying different dyes
IPC: D06B11/00
Filed: 1977-02-17
Abstract: The process to apply random multi-colour dyestuffs to yarns, arranges the yarns in a tubular pattern to be advanced continuously through an assembly of sprays, which apply to different dyes to the yarns. The dye sprays are radially aligned to cover the whole surface area of the tubular yarn structure to give the random dyeing effect. A carrier frame is formed by four screws converging towards each other. The screw are rotated. The yarn is guided to give a yarn coil in a reciprocating movement along the axis of the array. The yarn, therefore is cross wound for the surrounding jets to apply the different dyestuffs. The system offers a cheap and simple yarn dyeing process which can be operated by unskilled operatives.

Filed: 1977-06-11
Abstract: A frame (1) which is raised and lowered with a sleeve (8) projecting downwards from it, forms part of a mechanism for removing screw caps (30) from bottles. Inside the sleeve is an inner sleeve (7) with a set of gripping jaws (31) at the bottom. This inner sleeve is mounted on a drive shaft (6) passing through the bottom (2) of the frame (1). Inside is a plunger (21) with a spring (24) around it, ending in a sensing part (20).
