Title: Chain joint and a method for its manufacture
Inventor: JOHNE FRANK ING GRAD
IPC: B21L13/00
Filed: 1981-08-29
Abstract: In a chain joint, connecting link or the like which has two essentially identical halves, an insert and a connecting screw, mating teeth are provided on the outside of short sides and on the inside of long sides of the two halves, and tooth profiles which can be fitted into one another are provided on the insides of both of the abovementioned sides and on the insert in order to achieve favourable conditions under stress. In an advantageous method for the manufacture of the chain joint, the teeth on the sides of the two halves are produced and the said halves are then assembled without the insert and subjected to tensile forces corresponding to those encountered in service, whereupon the tooth profiles on the insides of the sides of the halves are produced. The chain joint is suitable for various types of chain and is particularly advantageous for round link chains used in mining. <IMAGE>

Title: Method and circuit arrangement for determining the spectral power of band-limited signals
Inventor: PORTSCHT RAINER DR ING
IPC: G01R23/16
Filed: 1981-12-17
Abstract: To determine the spectral power of band-limited A/D converted signals in accordance with the equation <IMAGE> particularly for monitoring call progress tones and for detecting DTMF signals, sin and cos oscillations with the amplitude values 0; +/-1/2; +/- 2ROOT 3/2 and +/-1, which are divided into 12 ranges, are used as reference oscillations and to each range, an accumulation memory is allocated for the respective amount of the digital value to be accumulated on the basis of its original sign and its consecutive number. After a predetermined number N of accumulated digital values, these are evaluated and combined. The power is then determined by forming the amount of the two quadrature components in a manner known per se. It is also shown that the method can also be carried out with PCM-coded samples companded in accordance with the A law and with 8-bit standard microcomputers in real-time mode.
Patent DE-3200664-A1 (DE)
Title: Electric motor without a commutator, having auxiliary magnetic poles
Inventor: HIROSE YUKIMI
IPC: H02P6/10
Filed: 1982-01-12
Abstract: An electric motor without a commutator has a cylindrical magnet rotor (7) with main magnet poles (7a, 7b, 7c, 7d) in which the N poles and S poles are arranged alternately in the circumferential direction and one axis of the N pole and S pole of one magnet in each case extends radially, and auxiliary magnetic poles (7') on one end side of the cylindrical rotor. The auxiliary magnetic poles are arranged in such a manner that the N poles and S poles of one magnetised region in each case extend axially. The magnetised region forming an auxiliary magnetic pole in each case has an arc dimension ( theta S) of 1/2  or less with respect to the electrical angle. Each of the magnetised regions forming an auxiliary magnetic pole in each case produces a predetermined change in the magnetic-flux-density distribution in the environment of rotation-position detection elements (HG1, HG2) in such a manner that the rotation position of the rotor can be detected precisely. In consequence, a circuit for changing over the armature currents by means of the precise information from the detection elements is controlled such that each armature winding is thus excited in the manner to be aimed for, and hence undesired torque ripple is reduced. <IMAGE>

Patent DE-3204957-A1 (DE)
Title: Method for the production of forgings
Inventor: ASBECK HEINZ
IPC: B21L5/00
Filed: 1982-02-12
Abstract: In order to produce forgings which have two parallel spaced plates which are connected to one another laterally by means of eye-like hoops, projections forming undercuts being provided on the inner sides of the plates, an extended preform is first produced, the plates lying in one plane and the pieces provided for the formation of the hoops being stretched essentially to their final dimensions. After the finish forging of the extended part in the die, the two plates are folded one on top of the other and, in the process, the hoops are bent. According to an alternative method, two ends of a billet are first of all squeezed or stretched and the ends are then pierced to form the eye-like hoops. After the splitting of the longitudinal sides of this preform, slides are introduced into that region of the preform where undercuts will subsequently lie. After the finish forging of the workpiece, the slides are pulled out of the forging.

Title: Terminating bar of an anti-insect net for windows
Inventor: BADEWIEN REINHARD
IPC: E06B9/17
Filed: 1982-07-07
Abstract: In order that the terminating bars holding the net stretched are as fast as possible, the terminating bar according to the invention is distinguished by a flat rail which is approximately C-shaped in profile and into which the end region of the net can be laid and by a sheet-metal strip which covers over the laid-in net and extends with at least one of its longitudinal edge regions into at least one of the undercuts of the flat rail formed by the C-profile shape, thereby clamping in the net laid in between. For shaping of the sheet-metal strip various configurations are possible in order to achieve a high rigidity of the flat terminating bar. Profilings of the sheet-metal strip formed by bending-off and bending-over operations are envisaged in particular for this.
Patent DE-3227429-A1 (DE)
Title: Apparatus for removing gristly parts from pieces of meat
Inventor: ADKISON FRANK L
IPC: A22C17/00
Filed: 1982-07-22
Abstract: The invention proposes an apparatus to strip gristly parts, for example tendons or cartilages, from pieces of meat. This takes place by a projecting piece of the cartilage or tendon being held down mechanically while the piece of meat encounters in its path a wedge-jaw arrangement which prevents the meat from any further continued movement, but on the other hand allows the cartilage or the like to continue running along the path until it is detached from the meat. In one embodiment, the wedge-jaw arrangement (14) is a machine component having two jaws (37, 38), which close for the wedge-jaw action, in order to strip the cartilage off the meat, and thereafter open again for easier removal of the detached cartilage. <IMAGE>

Filed: 1982-10-28
Abstract: A hydraulic device (10) for controlling a lifting mechanism in tractors is proposed which permits a reliable and quickly operating hydraulic limit position switch-off accompanied by fully hydraulic signal processing in a control circuit. In the control circuit (12) which is constructed as a complete bridge circuit and in whose bridge diagonal (38) the displacement valve (14) with its control terminals (19, 22) is located, the bridge diagonal (38) is connected to a three-way two-position control valve (41), two non-return valves (44, 49) in a first connecting line (43) and in the diagonal (38) prevent an undesired pressure compensation between the centre pressure tap-offs (36, 37) of the complete bridge circuit during the limit position switch-off but permit the desired pressure compensation in the control terminals (19, 22). The control valve (41) which is actuated by the lifting mechanism (24) in its top position controls the displacement valve (14) in such a way that it reliably moves back into its neutral position (18).

Title: Safety boat which has automatic self-righting capacity and/or is absolutely unsinkable
Inventor: PONTAI FARKAS BELA
IPC: B63C9/02
Filed: 1983-04-25
Abstract: To afford the greatest possible protection and to safeguard human life on the water, in particular at sea, the safety boat is provided with hermetically sealable and/or filled barrier spaces, placed below and also above the water level, and also with a base weight placed in the keel area. The parts described can also be subdivided and/or can be dismountable. The occupants are placed close to the bottom plane of the boat and the seats are equipped with retaining safety installations. The various known physical laws utilised here will exert an automatic effect in this safety boat in such a way that this boat together with the occupants can never remain overturned. Its automatic self-righting capacity will always force the boat back to its horizontal basic position. Due to the barrier spaces filled with water-tight materials, this safety boat at the same time also becomes completely unsinkable. In an emergency, the occupants of the safety boat, who are securely held by the safety installations, are thus protected from drowning and from being washed overboard.
