Patent DE-2831678-A1 (DE)
Title: Sailing dinghy with outrigger - incorporates swivel connection to secure outrigger on either side of main hull
Inventor: SEEFLUTH INGO WILHELM
IPC: B63B1/14
Filed: 1978-07-19
Abstract: The outrigger for the sailing boat is linked to the main hull by a boom which can ber set either side of the hull. The hull end of the boom is on a locking pivot so that the outrigger can be swung round the bows to change side. The outrigger provides maximum support in any sailing conditions. It is symmetrical front and rear so that it can be swung to either side of the main hull without loosening the boom supports.

(as Ti) of a Ti trihalide in which the halogen is Cl and/or Br, and (c) 0.01-4 ptS. wt. (as Mg) of a Mg cpd. which is soluble in the alcohol (2a). The wt. ratio (I):T2 = 1:0.01-1:0.2 and the wt. ratio (I):Mg is 1:0.01-1:0.25. The resulting dispersion is then subjected to azeotropic distn. at 10-140 degrees C, opt. with replenishment of the hydrocarbon (1a), until alcohol is no longer present in the distillate, to form a suspension. Catalysts are less hazardous to handle and cause less environmental pollution than prior art carrier catalysts. The catalysts give high polymerisation yields and constant specific yields with time. The polymers produced have good morphological properties, esp. a high apparent density and a low fine grain content.

Title: MM-wave radio network - uses frequencies lying at max. atmospheric attenuation to reduce number of frequencies needed
Inventor: FISCHER KARL DIPL ING
IPC: H04B7/24
Filed: 1979-01-30
Abstract: The radio network has its frequencies chosen to lie at places in the spectrum of max. atmospheric attenuation. The frequencies are not chosen, as is usual, to lie at points in the spectrum that give the greatest range for the smallest transmitter power. Example: An attenuation peak exists at 60 GHz. This frequency is therefore chosen for the radio network and typically results in clear-day range of 2 km and a rainy-day range of 1.5 km and requires nine frequencies to serve an area of any size, i.e. by repeating the frequency pattern. The usual method would require thirty six frequencies to serve an area of any size.

Title: Stabilising weight system for bicycle - has set of sprung bobweights in symmetrical arrangement on spokes
Inventor: VOLZ PETER
IPC: F16F15/31
Filed: 1979-07-10
Abstract: The stabilising weight system for a bicycle wheel has pairs of equal weights on opposite sides of the wheel hub and held in sprung mountings. The weights are displaced by centrifugal force and move to absorb changes in wheel speed, for a smooth rotation. The weights (6) slide along the spokes (7) and are held in rest positions between opposing springs. The weights are displaced so that wheel speed changes due to pedalling are evened out. Also the weights provide a store of energy for additional torque on small inclines.

Title: Mounting hollow rivet-like connectors on circuit board - involves perforated sorting plate whose vibration sets connectors in holes for press fitting into circuit board bores
Inventor: VIEHWEGER HERMANN
IPC: H01R43/20
Filed: 1979-09-03
Abstract: The connector-fitting machine deposits an excess of the connecting rivets (2) onto an aligning perforated plate, which is vibrated until all its holes have been filled by connecting rivets. The surplus rivets are removed and the aligning board pressed against the circuit board (1) so that the rivets enter the bores in the circuit board. The aligning plate has a template (4) with holes for the rivets and a guide plate (5) with a countersink to guide the rivets into the template holes. Press posts (11) push the rivets from the aligning plate into the circuit board, deforming the template in the process.

Title: Corrosion repair of buried steel tank - uses sealing plate and expanding fastener, to avoid excavation of tank
IPC: B65D90/00
Filed: 1980-03-10
Abstract: For the repair, an aperture is cut into the tank wall (2), the aperture being larger than the corroded spot; and a larger recess is cut into the ground surrounding the aperture. The external insulating cover around the edge of the aperture is mechanically removed, and a hardening filler (22) is brought into the recess in the ground. An expanding fastener (26) is inserted into the recess, so that it is enclosed by the filler. A sealing plate (24) with a plastics coating is connected to one end of the fastener, and the coated side engages on the inner tank wall around the aperture. The fastener is then expanded so as to engage around the tank wall and press the plate against it. A heater is brought into contact with the plate, to harden the plate coating (28) and the filler.

Filed: 1981-02-21
Abstract: The invention relates to an arrangement for monitoring the drawing of the supporting frame in a cutter shield, the supporting frame of which can be drawn up by means of the jacks allocated to the driving cutters. In order to prevent the driving cutters from unintentionally running back during the drawing of the supporting frame, at least one of the driving cutters is provided with a switching device which, by striking against a fixed abutment (end casing) during the cutter return, triggers a warning signal and/or a control signal blocking the drawing of the supporting frame. The switching device preferably consists of a switch which is provided with a holding magnet, adheres magnetically to the driving cutter and is held by a holder at the fixed abutment (end casing) so that it cannot be carried along by the driving cutter when the latter is advanced.
