Patent DE-2816648-A1 (DE)
Title: Filled wafer spreading machine - automatically controls filling layer thickness by counted number and weight
IPC: A21C15/02
Filed: 1978-04-17
Abstract: A machine to spread a filling paste on pastry such as wafers counts the number of the arriving pieces and adjusts the spreading speed accordingly. The amount of the paste, spread over the wafers, is controlled in addition by the weight of the finished stack of wafers. The machine achieves uniform results in spite of the fluctuating flow rate to suit variations in the speed of the preceding bakery equipment. Specifically a belt conveyor takes the wafers to a switch which can be set by a motor either to conveyor. Both run faster than the spreader so that the single wafers are pushed into a continuous strand.

Title: Gas-tight bulk material discharge - through L=shaped transfer tube urged between outflow chute and charge hole
Inventor: KUCHARZYK WERNER
IPC: C10B31/04
Filed: 1978-05-08
Abstract: Bulk material, e.g. preheated coal, can be transferred from a conveyor to a charge hole by equipping the conveyor with an outflow chute in which a butterfly valve is arranged upstream of a gastifght flange. The flange can be replaced by a tube in the shape of an inverted L which is lifted up and tilted by a power cylinder. One or both seals of the tube ends have a certain freedom of motion. Such a discharge device is simple to operate and very robust in service. In ensures a gas-tight seal even when thermal elongations or other reasons have caused dimensional discrepancies between the parts to be sealed.

Title: Inhibiting lead corrosion in drinking water systems - by adding soluble carbonate and maintaining pH at specified level
Inventor: PATTERSON JAMES W
IPC: C02F1/66
Filed: 1978-05-31
Abstract: The process comprises adding to the water a source of water soluble carbonate in an amt. necessary to assure the passivation of the pipes comprising lead contg. elements. The pH of the water is maintained at 7.5-9. Pref. the carbonate content, expressed as CaCO2 is maintained at a minimal amt. of about 20mg/l. The water pH is maintained at 0.5-9 in a manner to form a layer of lead carbonate to assure the passivation of the lead. The process is partic. applied to drinking water, usually of lower pH and low carbonate content, which is corrosive to lead resulting in too high a lead content in the water (normal environmental limit 0.5mg/l). The method is very effective whereas previous processes such as pH adjustment or adding orthophosphate are limitedly effective and ineffective respectively.

Title: Body support shell for disabled persons - produced from hose sections filled with polyurethane foam
IPC: A47C31/12
Filed: 1978-07-21
Abstract: A body support shell for disabled persons is prepd. on a reclining structure with a back rest, a seat, a leg rest and a foot rest, all adjustable in length. A plastic mattress, filled with plastic foam beads, is connected to a vacuum system. The body support shell consists of hose sections, filled with polyurethane foam, for the back, seat, leg and foot parts, with joints between the sections. The patient rests on them until the body support shell has hardened to a contour which moulds the contours of his body. The result is a shell which is more relaxing for a patient than a plaster-of-paris shell made with the patient lying face down on a table and with the legs hanging down. It is also less labour intensive.

Title: Holder for miniature lamp or LED - has electrical spring contact and location for lamp envelope
Inventor: FEGER ROLF
IPC: H05K7/12
Filed: 1978-12-02
Abstract: The complete holder consists of a base and a hollow housing for holding the lamp and enclosing the electrical connections.

Title: Metal spigot and socket pipes for underground pipelines - where each pipe is connected by cable to anode used for cathodic protection of pipe against corrosion
Inventor: THON JOACHIM DR ING
IPC: C23F13/02
Filed: 1979-02-24
Abstract: The pipes have rubber seals, and possess an electrically insulating outer sheath, plus >=1 anode which is inserted in the earth for cathodic protection of each pipe. The anode is pref. a rod which is located inside the pipe while the latter is transported; and the rod is pref. connected by a cable to a conductor shoe spot welded onto the end of the socket on each pipe. During the transport of the pipe, the anode is pref. surrounded by an elastic cushion which fills and closes the end of the pipe, which pref. has a rounded internal flange on the end of the socket. The anode is taken out of each pipe for assembly of the pipeline. After laying a pipeline, it is normally necessary to employ specialist firms to provide cathode protection. The invention provides anodes and cables fixed on the pipes before the latter leave a factory, so the pipe layers can install the anodes.

Title: Steam gasification of coal - combined with hydrogasification of lignite
Inventor: FREWER HANS DR ING
IPC: C10J3/72
Filed: 1979-03-06

Title: Traverse drive for spraying head of coating machine - using endless belt for rapid reversal of traverse direction
IPC: B05B13/04
Filed: 1979-07-14
Abstract: Equipment for coating the back of a continuous length of carpet material has a spray head moving to-and-fro along a rail above and at right angles to the direction of movement of the material. The spray head is driven by an endless belt, which is parallel to the rail and has a constant velocity, whose length corresponds essentially to the width of the material to be coated. The blet effects a rapid reversal of the spray head ar the end of each traverse without complicated mechanisms. Reversal time is cut from about 0.15 sec. with previously-employed devices to about 0.05 sec., which reduces the spray overlap at the edges of the material from 23 cm. to about 5 cm.

Title: Torque equalising device for e.g. camera swivel head - transmits torque to springs via lever arms with variable length and displacement component
Inventor: DANEK ANTONIN
IPC: F16M11/10
Filed: 1979-12-28
Abstract: The torque is generated by tipping a pivotally mounted body about a stationary axis of rotation. The balancing device has a stator portion and a rotor portion, forming the body or retaining the same. The stator and rotor portions are swivelably connected via the stationary axis of rotation. A spring between the stator and rotor portions exerts a resetting force opposing the torque. The torque transmission to the spring takes place via lever arms, whose effective length and/or the displacement component effective to deflect the spring varies during swivelling of the rotor portion relative to the stator portion with the change of the torque. Preferably at least one spring used has a linear characteristic. The deflection direction being also linear. The variation of the lever arm length and/or the effective display cement component may vary to such an extend that the resetting torque changes with the cosine of the swivel angle.

Patent DE-3001158-A1 (DE)
Inventor: CONTALBRIGO EDGARDO
IPC: H02G1/14
Filed: 1980-01-15
Abstract: This is a method for joining high-voltage cables by means of a prefabricated sleeve capable of withstanding a large elastic deformation. The method is characterised by the use of a tool, called a radial stretching device, which includes a hollow central part (21) and which consists of two semi-cylindrical segments (22) and (23) which can be juxtaposed so as to form the tube-shaped component (21). These segments include, at their ends, a separating device consisting of two bolts (30) and (31) mounted on two semi-circular segments (24) and (25). In order to slip the prefabricated sleeve over the radial stretching device, the central hollow part (21) is surmounted by an ogival component (33). In order to make the joint, the prefabricated sleeve is installed over the radial stretching device, the ogival component (33) is removed and the tubular central part (21) is slipped over one of the ends of the cables to be joined. After joining the conductors of the two cables, the prefabricated sleeve is installed and the radial stretching device is withdrawn, which leads to the retraction of the said sleeve and its gripping onto the ends of the cables to be joined. <IMAGE>
