Title: Appliance for loading pressure-sensitive material from a stockpile, especially for loading sugarbeet onto a transport vehicle for transportation away from the field
Inventor: SALMANSBERGER JOSEF
IPC: E02F3/30
Filed: 1981-01-20
Abstract: To provide an appliance for loading especially sugar beet onto a transport vehicle for transportation from the field, a conventional mechanical shovel is modified by subdividing the tilting jib (8) into a main part (9) and a cantilever (10) which is pivotably adjustable in the customary way relative to the main jib (7) of the jib system (4) via a pivot mounting (11) of horizontal axis (12) and on which, on the other hand, the rear end of the main part (9) of the tilting jib (8) is mounted pivotably about a pivot axis (19) essentially parallel to the longitudinal extension of the tilting jib (8). The loading shovel (15), which is appropriately designed as a mesh basket, can thereby be pivoted out of the conventional front position into two side positions relative to the jib plane, which are pivoted through approximately 90 DEG with respect to the front position and in which a lateral conveyance of the material from the ends of the stockpile to its middle region can take place via the pivoting drive between the undercarriage (1) and the machine frame (2) of the mechanical shovel. To obtain an adjustment of the bottom surface (21) of the loading shovel (15) parallel to the ground, in addition to the conventional tiltability of the loading shovel (15) about a pivot axis (16) essentially parallel to its front edge, there is a tiltability about a further pivot axis (22) which has a component parallel to the side edges of the loading shovel (15), so that the loading shovel (15) can be oriented parallel to the ground in the direction of both its front edge and its depth. <IMAGE>

Patent DE-3114964-A1 (DE)
Title: Centrifugal drive
Inventor: FREUDENAU GUENTER
IPC: F16H33/20
Filed: 1981-04-13
Abstract: Probably the simplest and best known form of a type of centrifugal drive is a centrifugal body swung around on a string. The circulating movement of the hand can be replaced by longitudinal movements. According to preparatory calculations, it is possible, in precise technical terms, to design a centrifugal drive in various ways with the intention of being able to take off the torque or, starting from a rotational movement, to provide the force of a reciprocating movement. Possibilities: design the axis/axes of the centres of rotation as a shaft or shafts, a spacer bar running radially and rotationally fixed thereon keeping the centrifugal body on a flat, near-elliptical orbit during the rotation. Connections from the axis of the centre of rotation designed as a shaft to the fixed output shaft by means of a flexible shaft, a cone transmission in conjunction with a longitudinally displaceable shaft; a design by way of a spacer bar and a further connecting rod (or the like) to the output shaft is also possible (with the intention of a connection which has sufficient tolerance but is rotationally fixed). The function of the spacer bar in conjunction with the axis of the centre of rotation designed as a shaft can also be undertaken by a roller of low height together with a connection, which has sufficient tolerance but is rotationally fixed, of the correspondingly designed centrifugal body to the output shaft. In the event of the output shaft being used as drive shaft, the force of a reciprocating movement is obtained. The centrifugal body may be designed as a generator/electric motor, the rotation taking place in a correspondingly formed casing (many possible forms). The corresponding centrifugal force can be controlled by means of a casing (many design possibilities for the interaction with a centrifugal drive), the form of which corresponds to the actual flat orbit which the suitably formed centrifugal body describes.

Title: Process for forming formwork structures, formwork structure and apparatus for carrying out the process
Inventor: RUETTENER JUERG
IPC: G09B25/00
Filed: 1981-04-14
Abstract: To produce formwork structures which serve, for example, as representation models, panels of thermoplastic material which, with the aid of heat, can be butt-welded, bent and cut are used as the working material. If appropriate, releasable connecting means can also be attached to the panels along certain connecting lines. As a result, a freely designable sheet-like structure or a lightweight hollow body is obtained. This result can easily be altered by cutting out and exchanging individual sheet portions.

IPC: F04B27/06
Filed: 1981-06-02
Abstract: A coupling arrangement for coupling a radial piston compressor to an external rotor drive motor is disclosed. The rotor of the drive motor is coupled to a rotatable cylinder block by arranging a plurality of leaf springs between the cylinder block and arms projecting from the rotor. The cylinder block rotatably mounted on the motor stator shaft supports the rotor at the compressor end of the drive motor. The leaf springs prevent canting of the cylinder blocks with respect to the rotor of the drive motor due to manufacturing and alignment errors.

Title: Broadband switching system
Inventor: PANZER KLAUS DR ING
IPC: H04N7/173
Filed: 1981-06-12
Abstract: The invention relates to a broadband switching system for television (TF) signals in which signals phase-modulated with the TV programmes can be switched via a broadband switching arrangement (KE1, KE2,...) and then transmitted in frequency-division multiplex via optical fibres (AL;...ALt) to the subscribers (T1...Tt). For TV programme switching in such a system, each TV programme (P1...Pp) is supplied to a plurality, corresponding to a plurality of frequency channels, of frequency-channel-individual switching planes (KE1, KE2,...) so that each subscriber (T1...Tt) in the said plurality of frequency channels has simultaneous access to a corresponding plurality of programmes (P1...Pp). In this arrangement, broadband-signal-modulated carriers of low carrier frequencies are switched through such switching planes (KE2, KE3) from which then in each case a suitable broadband-signal-modulated carrier harmonic is filtered out for frequency-division multiplex transmission; the frequency deviation of the lower-frequency carrier must be specified to be lower by a factor corresponding to the ordinal number of harmonic than the frequency deviation desired in the frequency-division multiplex system. <IMAGE>

Title: Device for setting a specific angular position of the crankshaft of an internal combustion engine
Inventor: HABERLA HERBERT
IPC: F02P17/04
Filed: 1981-11-21
Abstract: Device for setting a specific angular position of the crankshaft of an internal combustion engine in relation to one of the two piston dead centres of a cylinder, in which a signal emitter is provided which senses a specific piston position and in which a geared motor connected to an angle pick-up, which motor can be coupled to the crankshaft, and an electronic measuring control device, to which the required angle can be fed, are provided, half of the angle described by the crankshaft being measured when the crankshaft rotates from passing the specific piston position to reattainment of that same position and the intermediate piston dead centre thereby being automatically determined, from the position of which dead centre the crankshaft is further rotated about the required angle and then automatically stopped. By measuring both of the crankshaft positions corresponding to the specific piston position under the same conditions, that is under tension or under pressure by the connecting rod, the bearing play can be eliminated. The device can be used for gauging crankshafts, setting injection pumps and ignition equipment and for setting specific positions of shafts, in general.

Title: Rig for a sailboard
Inventor: DUSCHEK HORST
IPC: B63B35/79
Filed: 1981-12-23
Abstract: The invention relates to a rig for a windsurfing board and has according to the invention two masts (8; 9), two mainsails (10; 11), a trimming sail (7), a curved boom (2) and two straight booms (5; 6), two struts (3; 4) and also a four-armed mast foot (1). One mast, one mainsail and one straight boom each form a rig half. The mast foot (1), the curved boom (2) fastened to the mast foot, and the struts (3; 4) produce the connection between both rig halves. Due to the special design of the mast foot (1), the mainsails (10; 11) are orientated at certain angles to one another so that propulsion is always produced on one sail but a relieving uplift is produced on the other sail. The trimming sail (7) fastened to a strut (4) functions as an elevator during "wave jumping". In this respect, the rig has balanced "flight properties" as well as generally better aerodynamic properties than conventional rigs of sailboards. <IMAGE>
