Title: Moisture exposable composite building slab - has concrete type core in partitioned chambers in plastics sheath
IPC: E04C2/20
Filed: 1976-07-16
Abstract: The composite building slab is esp. suitable for bathrooms, laundry rooms, kitchens and other moisture-exposed spaces, or to weather-exposed parts of buildings; it comprises a sheath of thin walled outside layers and an intervening core substance. The sheath (11) is made of plastic, and has laterally spaced cross arms (12) which form a large number of small-cross-sectioned holding compartments (14) for the core material (15). The latter comprises hard-setting mainly mineral material which can be cast or heaped, and which is finally several times as rigid as the sheath. Concrete is a suitable core material. Servicing ducts may be built into some of the compartments.

Title: Hydrogen fluoride mfr. from fluorspar and sulphuric acid - includes pre-conversion to calcium hydrogen fluoride to accelerate reaction
Inventor: EIPELBAUER EDUARD PROF DIPL IN
IPC: C01B7/19
Filed: 1976-07-31
Abstract: In the mfr. of HF by reacting Ca fluoride with sulphuric acid and/or SO3 and water, the Ca fluoride is first largely converted to Ca-H fluoride (I) and then this is reacted with sulphuric acid to Ca sulphate and HF, opt. after thermal elimination of the HF. Activation of the fluorspar with HF greatly increases the reaction rate compared with natural fluorspar. The process is simple and economical and gives high yields. In an example 100g fluorspar were added to 1200 g soln. of 62.9% HG, 26.3% sulphuric acid, rest water, contg. (a) 0, (b) 20g (I) seed crystals, at 22 degrees C. The degree of reaction was (a) 98.7% after 8 h, (b) 98.5% after 5H.

Title: Decorative surface shaping and packaging of butter or margarine - uses suitably shaped stamped thin mould subsequently removed by finger pressure
Inventor: PETERS LEO
IPC: B65D85/74
Filed: 1976-08-20
Abstract: Butter or margarine portions have their surface formed into a decorative shapes using a readily deformable package comprising a thermally deformable plastic sheet 0.12-0.5mm thick into which the butter or magarine is fed in liquid form through an opening in the sheet. The angles on the peaks of the moulded surface of the dairy product must be no less than 20 deg. and the radii of the tops of the pressed surfaces must not be less than 0.8mm so that finger pressure against the outside of the hollow form exerts a collaborative and/or expanding movement on parts of the pressed surfaces thereby causing the portion parts to become separated without damage if the temp. of the portions is between 3 deg. and 9 deg..

Title: Earth faults detector in compensated HV networks - has AND=circuit to whose inputs various monitoring stages are connected
Inventor: HADICK WILHELM ING GRAD
IPC: H02H3/16
Filed: 1976-10-26
Abstract: The detector delivers an output signal for selective disconnection of an affected line section when a number of operational variables simultaneously appear which are characteristic for an earth fault. A first input of an AND circuit (6) is engaged by an overcurrent output of an overcurrent stage (1) monitoring the current sum (sigma I); a second input of the AND circuit (6) is connected to overcurrent stages (2) monitoring individual phase currents in all lines connected to the monitored area, or with excitation circuits for sub-impedances. In the rest state the inputs deliver a continuous signal to the AND circuit (6), whose third input is connected to an overvoltage stage (5) measuring the neutral point voltage shift. The AND circuit delivers the output signal.

Title: Portable tester for spark plugs - has receptacle fitted with manually operated piezoelectric generator
Inventor: HUT GUENTER L
IPC: G01R31/00
Filed: 1977-01-24
Abstract: The piezoelectric tester for spark plugs used in automobile engines consists of an insulated housing in which the plug under test is inserted inverted so that electrical connection can be made via clips to the centre terminal and the metal body of the plug. The clips are connected to the terminals of a piezo-electric, HV spark generator. The test voltage is generated by manual operation of the trigger button which protrudes from the upper edge of the insulating housing. The performance of the plug electrodes can then be observed. A spark-gap enclosed in a transparent housing is also available for checking the tester and this plugs into the unit in the same way as the plug under test. The tester is simple to use and operates completely independently of the motor car engine.
