Title: Non-smectic liquid crystal indicator mixt. - contg. polar and non-polar components and having positive dielectric constant and negative anisotropic conductivity
Inventor: HEPPKE GERD DR
IPC: C09K19/42
Filed: 1976-09-30
Abstract: A non-smectic liquid crystal mixt. consists of >=2 components. The first, polar component contains >=1 polar end gp and has a +ve anisotropic dielectric constant. The second, non-polar component contains 2 non-polar end-gps. The non-polar component, together with the polar component, can form a stable, smectic and/or solid phase in a limited mixing range. The proportion of the polar component in the mixt. is so small that the smectic or solid phase is not yet present. A pref. non-polar component is a cpd. having formula (I): (where M and M' are -N=N-, -CH=CH-, -CH=CCl-, -N=N(O)-, -CH=N-, -C=C-, -COO- or -COS-, and either M and M' can be omitted. X and Y are alkyloxy, alkyl, alkanoyl, alkanoyloxy or alkoxycarbonyloxy gps.). The polar component differs from the non-polar component in that one of X and Y is replaced by -CN, -NO2 or -Cl.

Title: Injection moulding plastic between walls - in which injection nozzles are cleared by presser elements after moulding
Inventor: KNUDSEN JOHANNES
IPC: B29C45/38
Filed: 1976-10-25
Abstract: A plastic is injected into a mould in the cavity between two walls so that the plastic forms a bond between the two walls. The plastic is injected through inlets and presser elements are advanced into the inlets to clear them of plastic after injection, and pusher elements clear away the waste plastic. The operation of the presser elements and pusher elements to clear the inlets takes about 0.5 secs. The method is used for injecting plastic into the cavities of walls of buildings. After moulding the operation is quickly and neatly finished off.

Title: Steel spiral reinforcing member for concrete - comprises high grade steel spirally wound without plastic deformation when stretched
Inventor: MIZUMA KATSUHISA
IPC: E04C5/06
Filed: 1976-12-06
Abstract: The steel spiral reinforcing member for use in concrete construction can be applied as a support stirrup loop or as a ring reinforcement unit. High grade steel is wound in a helical configuration, without sustaining any plastic deformation when it is stretched out from the fully pressure-loaded condition. The steel has a yield strength over 55 kg/mm22. A rounded-off head may be formed at the end of the member. The original material can be worked into a spiral shape with helically aligned recesses on the periphery, by heating to the normal temp; or it can be cold worked and then heated to 200 deg. to 400 deg.C. This can be stretched smoothly and without friction, to form part of an entity adhering durably to the concrete.

Title: Suspended conveying or protection pipe position control - uses inherent righting capability to suit support advances, with guides and linkages
Inventor: WINKLER JOHANNES
IPC: E21D23/00
Filed: 1977-03-15
Abstract: The advancing supports entrain the pipe which flexes (10, 11) according to the support movements. This flexing is achieved using end stops (4) which draw the pipe securements forward with it to the end of the advance step(s). The securements (31, 32) of the pipes on the adjoining as-yet unadvanced supports (B, B1), are also moved forward by an amt. proportional to the bend line. The pipe starts halfway along the advance step (2) so that securement on the unadvanced unit remains stationary and securement on the advancing unit moves back. These movements are assisted by a sloping guide so that the weight of the pipe restores its position each time. At least one securement of the pipe can only move backward, whilst the remainder can deviate sideways.

Title: Centrifugal cleaning device for fleece paint rollers - has spray nozzles allowing water to turn and spin roller inside container
Inventor: AIERSTOCK FRITZ
IPC: B44D3/00
Filed: 1977-04-16
Abstract: The centrifugal cleaning device for sheepskin paint rollers comprises a dirt collecting sleeve (1), a clamping device (2), the spray nozzle pipe (3) and a water pipe (4). The roller (W) is suspended by its arm in the positioning slot (5) of the dirt collecting sleeve so that the axis of the roller runs parallel to that of the sleeve and the arm of the roller is held firm in the clamp. After connecting the water pipe to the tap water can be turned on to produce several jets (7) which run tangentially to the roller and cause it to turn. The centrifugal forces arising at the roller automatically spin the water and paint out of the roller for an intensive cleaning action.

Title: Direct calorimeter for respiratory moisture enthalpy - has calcium chloride surrounding lithium chloride cylinder
Inventor: MIRTSCH FRANK DIPL ING DIPL PH
IPC: G01N25/48
Filed: 1977-09-22
Abstract: A direct calorimeter to measure the heat emitted by the body of an animal by conduction, convection, radiation and enthalpy of the respiratory humidity is based on a modified Li Cl -Ca Cl2 dew-point hygrometer and a gas-filled gradient layer. The calorimeter is made of transparent material and faces and urine of the test animals are discharged separate from each other.
