Title: Inertia and impact fuse for non-spinning - rockets
Inventor: SPINELLI UMBERTO
IPC: F42C15/24
Filed: 1969-07-03
Abstract: Inertia and impact fuse has a primer which is disposed in a radially movable carriage provided with a bore aligned with the impact pin of the missile, the carriage which is spring biased towards the cental axis of the missile being blocked against premature radially inward displacement by an axially movable safety pin. On firing of the missile the impact pin enters the aligned bore in the carriage to prevent its displacement whilst the safety pin is displaced axially against the bias of its spring, whereby during the course of the flight of the missile the impact is returned to its original such that the carriage is moved radially inwardly to align the primer with the impact pin. Radial displacement of the carriage is controlled by a gear trains which acts as a braking element. On impact the impact pin set off the primer which is then aligned with a pyrotechnic chain. Fuse is cheap to manufacture and can be used on sandy or marshly soils. Fuse on a account of the provision of carriage has improved safety properties during transport, handling, flight of missile or parachute drop.

Title: Fixed bed gasification system - using crushed coal and tar extruded and briquetted directly into producer shaft
Inventor: FURMAN ANTHONY HOLMES
IPC: C10L5/02
Filed: 1972-11-17
Abstract: A fixed-bed gasification system for run-of-mine coal uses a finely crushed coal, mixed with a suitable binding agent, as the raw material. This mixture is extruded by a worm extrusion press into the top of a gas producer shaft where the extruded strand is chopped off into briquettes for distribution over the top of the fixed bed. Instead of briquettes, the run-of-mine coal can be mixed with hollow silicon carbide cylinders and allowed to descend in the fixed bed. This prevents the caking of swelling coal in conventional fixed-bed gasification systems. More heat is retained than in fluid-bed systems and the coal is devolatilized before it is gasified.

Abstract: The bobbin is fitted with a band brake, the circumferential angle of which is variable. The filament is guided through a loop attached to a spring-loaded connecting rod. The other end of the connecting rod is guided by a curved slot and holds the anchoring point for the brake band. On increased tension in the filament, the loop, connecting rod and anchoring point of the band are moved, thus reducing the circumferential angle. Alternatively, one anchorage point of the brake band can be at a lever, which is part of a spring-loaded crankshaft. Guiding loops for filaments are attached to the crankshaft. This is pref. used for a number of filaments.
Patent DE-2315836-A1 (DE)
Title: Knitting, esp. circular knitting, machine needle - has integral stamped-out spring, instead of bowing whole needle shaft
Inventor: KOHORN ALFRED OSWALD
IPC: D04B35/02
Filed: 1973-03-29
Abstract: The spring is formed by stamping out a slit in the needle shaft, about midway between the ends, leaving the stamped out portion attached at one end and giving the other end an enlarged or rounded head and bending it back towards the needle shaft to rest on the face thereof (rather in the fashion of a pocket clip for a pen). Such a needle can then lie with its flat face against one wall of the cylinder (or dial) groove and the spring pressing against the other wall. This gives better needle guidance, giving higher quality knitting at high speed, than when the whole needle is bowed so that the ends only contact one groove face while the bowed centre section contact the opposite groove face.

Title: Adhesive coating apparatus - for uniform distribution of adhesive on fibrous matter e.g. from wood, in the mfr. of fibre or chip-board
Inventor: FOERSTER HERMANN
IPC: B27N1/02
Filed: 1973-09-01
Abstract: In the adhesive coating of wood, bagasse or similar, and partic. cellulosic matl., fibres, in which adhesive is added to the transported fibres and thereafter the mixt. is held in motion to bring about distribution of the adhesive, the mixed matl. is subjected to point or linearly acting pulses in the direction of advance, and in partic. such pulses in known manner maintain the mixt. in rotation round a common axis and their mean total intensity is selected in such a way that the mixt. occupies a major part of the interior, axially-adjacent space in the mixing zone. The method prevents the formation of clumps or agglomerates formed by e.g., rolling up by the action of friction forces on the wall of the treatment drum, before the adhesive has been uniformly distributed over the fibres or chips, so that a higher quality chip- or fibre-board is obtd.

Title: Generator-motor set - has resistor in excitation cct. shorted by timer relay when motor reaches running speed
Inventor: VOLKMANN HELMUT
IPC: H02P9/10
Filed: 1973-10-15
Abstract: The generator/motor set has the motor coupled over contactors to the phase lines. The generator is coupled over another contactor to the same phase lines. When the motor is to be switched to the already running generator, an additional resistor is switched into the generator's excitation winding circuit to reduce the generator output. This allows the motor to start slowly. When the motor is running, a relay shorts out the resistor so that the generator's full power is delivered to the motor. The generator voltage can be set by a variable resistor in the excitation circuit.
