The strips vary in length to account for the variation in the number of days in a month.
Patent DE-2721081-A1 (DE)
Title: Ceramic slip material injection arrangement - has metering cylinder with piston and valve ensuring correct mould filling
Inventor: EIGEN ULRICH ING GRAD
IPC: B28B1/26
Filed: 1977-05-11
Abstract: The arrangement includes a piston sliding in a cylinder. The cylinder metering chamber contains the slip which is injected through nozzles into the cavity of a mould. The mould consists of a liquid-permeable porous material which, however, retains ceramic particles. The slip is accurately metered to completely fill the mould chamber without overloading. No air penetrates into the metering chamber, ensuring accurate metering. Number of moving parts is reduced to ensure that material debris does not adversely effect formed blanks. The injection piston has a valve seat, and the coating element which moves along the axis of the cylinder acts in conjunction with the valve seat and the nozzle. Supply of slip into the metering chamber is prevented during the injection movement. During the return movement of the injection piston the supply to the metering chamber is released and connection between the metering chamber and mould cavity is blocked.

Title: Drag type separator for gases using aerofoil elements - having lattice of elements across flow passage with grooves along side to collect solid particles collecting in boundary layer
Inventor: WINTER KARL DIPL PHYS
IPC: B01D45/04
Filed: 1977-11-25
Abstract: Particle impurities in gas streams are separated using a drag type separator. This has a number of aerofoil elements arranged as a lattice across the flow passage. Each element has a groove along the side which feeds into a draw off passage. The gas is accelerated to 30 m/sec past the element. The grooves are located immediately after the thickest portion of the element. The volum of boundary layer drawn off w.r.t. the main flow is in the ratio 1:5. Used to remove entrained dust particles and moisture droplets in air or other gas streams. The pressure loss through the separator only corresponds to the work necessary to remove the particles to cause vortexing and turbulence are much reduced.

Title: Accelerator pump for fuel injected automobile engine - has separate pump chambers for separate engine cylinders for quick response
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F02M69/44
Filed: 1978-07-21
Abstract: The pump has a separate working chamber (2a, 2b) for each engine cylinder. Each chamber has an inlet valve (3a, 3b) from a fuel reservoir (6) and a discharge valve (14a, 14b) to a delivery pipe (16a, 16b). A separate delivery pipe from each chamber each leads to the inlet connection (20a) of its own engine cylinder. The pipe discharges into the inlet close to the cylinder through a non-return valve (22a). This reduces the time lag between pumping and injection. A membrane (7) common to all the pump chambers provides the pumping action. It is depressed against springs (8a, 8b) by plungers (10a, 10b) operated in common (9) from the accelerator pedal.
Patent DE-2835108-A1 (DE)
Title: Releasing compacted sugar crystals from centrifuge screen - using sudden applied braking force to screen (BR 26.9.78)
IPC: C13B30/06
Filed: 1978-08-10
Abstract: Sugar crystals are sepd. from fluid matter using a centrifuge rotating at >1,200 r.p.m. The crystals are restrained from movement beyond a predetermined point by a screen mounted to the inside surface of the rotating drum of the centrifuge. The fluid passes through the screen. A braking force is applied to the drum to bring it to rest in 1 second. The crystals disengage from the screen and continue rotation by the resulting inertial force. They eventually drop to the bottom of the drum from where they may be removed. Pref. the drum is slowed down to about 200 rpm prior to the application of the braking force. The method is used in the refining of sugar during the sepn. of sugar crystals from the syrup fraction of the massecuite, magma or mother liquor. The removal of the sugar crystals by the application of a sudden braking force eliminate the use of a scraper which can damage the crystals and can occupy a considerable time.
