Patent DE-1947061-A1 (DE)
Title: Riser reactor
Inventor: JOHANNES ZUIDERWEG FREDERIK
IPC: B01J8/08
Filed: 1969-09-17
Abstract: Riser-reactor in which a granular solid and gas are contacted so that chemical or physical processes such as the catalytic cracking of petroleum or petroleum fractions may be achieved. The equipment includes an inlet through which gas and granular solids are admitted and above this one or more rings of symmetrically arranged injection tubes through which gas is laterally introduced into the riser-reactor. The advantages of the riser-reactor are that a reactor with a fluidised bed is no longer necessary or may have a smaller capacity. The lateral injection of gas reduces the maldistribution of solids which tends to occur in a riser reactor and reduces the times of contact between the solid and the gas. In the process for the catalytic cracking of petroleum the cracking and regeneration of the granular catalyst can take place in separate riser-reactors thus saving considerably on reactor costs.
Patent DE-1966986-A1 (DE)
Title: Reversing unit for ink ribbon - has rotatable drive which can be coupled to roller carrying ribbon
Inventor: REIMER HERRMANN GUENTER
IPC: B41J17/14
Filed: 1969-06-24
Abstract: Two rollers are provided, each with a rotatable driver coupled to the output disc of a toothed shift coupling in whose coupling disc engages a crank of a parallel cranked linkage rectangle. The coupler of this latter assembly forms the output element of a tiltable spring assembly whose input element forms a double-armed reversing lever. The coupling input part of the toothed shift coupling is connected non-rotatably with a centrally arranged gear wheel. An automatic reversing of the direction of movement of the colour band is thereby achieved, the responsible unit being installed on one side of the band, leaving the other free for the application of a diagonally moving correcting arrangement. A single electric motor suffices for movement in both directions.
Patent DE-2001741-A1 (DE)
Title: Colouring sugars
IPC: A23L5/43
Filed: 1970-01-16
Abstract: Sugars for admixture with coloured food powders are pre-coloured by adding is not 5, pref., 10%, maltodextria, and 5-10% foodstuff colouring, spraying the (moving) mixture with is not 5, pref. 10%, water, and drying at 60C, pref., 90C, and ca. 12 mm Hg.

Patent DE-2013326-A1 (DE)
Title: Periscope with securing unit to avoid impact damage
IPC: G21C17/08
Filed: 1970-03-20
Abstract: The periscope is suspended in pendulum fashion and connected to one or more limit switches which generate a stop-impulse for the drive motor when the periscope deviates more than a predetermined amount. The equipment is suspended using a rigid ring bearing joined to the two-sided arms of a double armed balance on whose free arm is located a counterweight to compensate for the wt of the periscope. The limit switches are joined to the free arm of the balance.
Patent DE-2014704-A1 (DE)
Title: Feeding coiled rod to a reinforcing meshwelding machine
IPC: B23K11/00
Filed: 1970-03-26
Abstract: Wire from a reel is led over a fixed pulley, under a moveable pulley, and over a third fixed pulley, before being guided through a straightening machine into the welder. The moveable pulley is weighted and slides up and down between limit switches which control the reel motor. When the rod is pulled through the welder, the centre pulley strikes the upper limit switch and causes the reel to pay off more wire. When the welder has sufficient wire, the pulley reaches the bottom switch and stops the motor. By having separate motors for pulling the wire into the welder and for feeding the wire off the reel, undue stresses in the wire are avoided. Reels with up to 4 tons of wire can be used, and these can be staggered with respect to each other to save space.

Patent DE-2049565-A1 (DE)
Title: Fibre reinforced plastic pipe - jointed by laminated half shells
IPC: B29C65/50
Filed: 1970-10-09
Abstract: Method for making laminated connections in pipes or tubes of fibre-reinforced reaction resin uses two half-shells of the external diameter of the pipe, furnished on the inside with a fibrous mat, already pretreated with hardener; the outer side of the shells is furnished with fibrous woven material or cords, impregnated with hardener; outside this again a self-adhesive strip is attached. Just before making the joint, the fibrous mat and fibrous cord are coated with an accelerated reaction resin and then the half-shells are fitted around the joint and are tightened up using the self-adhesive strip. Typically, the self-adhesive foil may be impermeable to water, thus protecting the reaction at the joint.

Patent DE-2319699-A1 (DE)
Title: Grid-cleaning appts. with articulated comb - for use in sewage evacuation channel
Inventor: ANGELE EDUARD
IPC: E02B8/02
Filed: 1973-04-18
Abstract: Appts. comprises a rod, which can pivot in the vertical plane around a horizontal axis, and a comb which is articulated at the end of this rod. The liq. in the evacuation channel is mixed with debris and flows up to the grid, which is madde from vertical rods placed close together; this holds the debris back and it is removed at intervals by the comb. When the latter is brought to its lowest point, it moves along the descending portion of the channel base; the teeth of the comb engage between the rods of the grid and then move upwards between lateral slides. The comb thus collects the debris and carries it upwards to the top of the plant. At this point it tips around its axis and the debris falls into a bin. The appts. can work in a restricted bay because of its low height.
