Title: Aluminium phosphate binder for porous aggregates - modified by addn. of other metal phosphate(s)
Inventor: HENTON PAUL V
IPC: C04B35/63
Filed: 1976-05-10
Abstract: Aluminium phosphate binder in an aq. soln. modified by addition of the phosphate(s) of Ca, Mg, Zn, Sr, Pb, Fe and/or Cd (pref. Ca and/or Mg and/or Zn), is improved in that the Al equiv. is 0.7-2.90 w.r.t. the equiv. of the other metal(s), and the equiv. of Al and the other metal(s) w.r.t. the equiv. of phosphoric acid is 1.0-1.8.

The porous components are mixed with the binder soln.; the mixt is moulded and fired. The molar ratios of the metals and phosphoric acid must be within the limits defined above to attain the maximal strength of the product. Suitable raw materials include quick or slaked lime, dolomite, zinc dust from zinc smelting, etc.

Title: Cover ring for underground heating pipes - has rubber or bitumen segments fitted between radial support struts
Inventor: PFEIFER JOACHIM
IPC: F16L58/04
Filed: 1976-05-31

Patent DE-2627557-A1 (DE)
Title: Two transistor switch for test purposes - uses approximate trapezium waveform to change switch with both transistors on for min. time
Inventor: KNICK ULRICH DIPL ING
IPC: H03K5/156
Filed: 1976-06-19
Abstract: The transistor switch has two (or more) transistors turned on and off alternately. The shape of the switching waveform (voltage) is initially approx. rectangular and then passes over into a trapezium shape. This shape is produced by a capacitor in series with two anti-parallel diodes. The advantage of this shape of switching waveform lies in its ensuring that the two transistors pass into their off or on states as quickly as possible and prevents them both being on for an unacceptably long time.
Patent DE-2629452-A1 (DE)
Title: Safety release ski binding - has leaf spring attached to clamp which holds ski boot in position until preset release force is attained
Inventor: MANFREDA WALTER
IPC: A63C9/085
Filed: 1976-06-30
Abstract: On a support for attachment to a ski there is at least one ski-boot clamp that is movable from a boot-clamping to a boot-releasing position. A leaf spring has one end disposed in the clamp while devices on the support hold the other end of the spring. The spring normally holds the clamp in clamping position but yields to a force sufficient to cause the spring to bend to permit the clamp to be moved out to boot-releasing position. The spring is curved transversely, with its concave side facing in the direction of the counter force that the spring exerts on the clamp while resisting movement of the clamp toward releasing position.

In this test, (I; R = OCH3, A = diisopopylamino) has an ED150 of 5.57 mg/kg i.v., while the known cpd., 1-(2-diethylaminoethoxy)-3-(o-methoxyphenoxy)-2-propanol HCl has an ED150 of 13.5 mg/kg i.v. Specific cpds., (I) include 1-(2-pyrrolidinoethoxy)-3-(o-methoxyphenoxy)-2-propanol. In an example, this is prepd. in 36% yield by reacting 1,2-epoxy-3-(o-methoxy-phenoxy)propane with pyrrolidinoethanol.

Title: Self contained escape gear - carries breathing gas supply stored in pipe coil inside hood
Inventor: WARNCKE ERNST
IPC: A62B7/02
Filed: 1976-11-13
Abstract: The hood-type self contained respirator is intended for use in emergency situations to enable persons to escape, when trapped by fire or smoke. The main parts of the respirator are the hood (1), pipe coil (3) with pressure reducing valve (4). The hood is made of a heat - and flame proof material and covers also the upper part of the body. The hood is fitted with a transparent visor (2) on the inner surface of which the ring-shaped breathing gas distributing header (7) with outlet opening (8) is installed. The distributor is fed with gas through a connecting pipe (6) which is fitted to a socket (5) forming the operating end of the shut-off and reducing valve (4). The respirator is stored in a folded condition in which the connecting pipe (6) is in such a position that the gas supply is cut off. When the respirator is put on over the head and the distributing header (7) with visor swings into operating position, the turning motion of the arm (6) opens the gas supply valve.

Title: Toy knitting machine - with crank wheel actuating reciprocating and turning needle and plastic frame feed mechanism
Inventor: KIMURA ASAMU
IPC: D05B81/00
Filed: 1976-12-02
Abstract: A toy knitting machine to knit yarn in loops around a continuous plastic grid frame consists of a crank handle, a feed mechanism for the frame and a needle which moves up and down and has a hook at the end. By coordinating a reciprocating movement with a twisting movement the yarn can be fixed in loops to the frame. The rotation of a crank on a wheel of the drive shaft turns a contrate wheel and through a gear wheel the disc which has a radial slot. A crosspiece with a pin which engages in this slot has a toothed rack in engagement with a gear wheel. This turns the needle with the hook at a certain point of its up and down stroke. All movements are derived from a simple turning of a crank handle.

Title: Rigid foam cellular dielectric - has gas pockets distributed to keep ratio of high breakdown volts to applied volts constant
Inventor: KUTSCHERA KURT DIPL ING
IPC: H01B7/02
Filed: 1976-12-15
Abstract: The rigid-foam cellular dielectric has a high breakdown voltaged and is for use as an inhomogeneous insulator between electrodes or similar. The dielectric has its breakdown voltage varied to suit the magnitude of the applied field at any point by altering the size of the gas pockets trapped in the foam. The ratio between the breakdown voltage at any point and the applied field is thus constant throughout the dielectric. The foam (3) is rigid enough to act as a support for the electrodes or similar that are being insulated.

Title: Synthetic filament washing unit - has a mesh drum to hold filaments through the fluid
IPC: D06B3/02
Filed: 1977-02-05
Abstract: The equipment to wash synthetic fibres uses a moving underlay to carry the filaments continuously through a washing process after they have been spun, so that the washing fluid passes through the filaments and the supporting underlay. The underlay is formed by a mesh drum with the washing fluid passing inwards from the outside of the drum. The system gives a short washing time, and prevents the filaments from floating during the washing process.
Patent DE-2707932-A1 (DE)
Title: Heat insulation for liquefied gas storage tanks - with frozen liq. foam filling the jacket cavity
Inventor: KLEIBOEMER KLAUS DIPL ING
IPC: F17C13/00
Filed: 1977-02-24
Abstract: Heat insulation of storage tanks for liquefied gases at low temps consists of the foam of a liquid with a freezing point above the temp. of the tank walls. The foam is introduced in the cavity between the tank walls and an outer shell. It is kept in the frozen state by the energy potential of the tank contents. Insulation is easier to apply than outside insulation with solid lagging and leaves the walls accessible to inspection. It is not sensitive to dynamic forces like inside insulation when the tanks are mounted on vehicles. It is not restricted to small tanks like the systems of holding the cavity at a vacuum.
