Patent DE-3118529-A1 (DE)
Title: Device for punching out parts thermoformed from thermoplastic
Inventor: ZUNDEL WERNER
IPC: B29C51/44
Filed: 1981-05-09
Abstract: The invention relates to a device for the optional punching out of only positively formed or positively/negatively formed parts. In the first case the sub-table is fixed, in the second case it executes an intermittent vertical movement, a formatted punching countersupport being installed. If only positive parts are punched out, by displacing links on the sub-table, an additional vertical displacement of the sub-table is effected. The drive via the links is designed such that, when the device is closed, a rigid unit exists and no punching force has to be absorbed by the drive.

Title: Door arrangement for an oven
Inventor: DETTERBECK HEINRICH
IPC: F24C15/02
Filed: 1981-07-27
Abstract: In known ovens with so-called baking carriages, the oven door is fastened rigidly angled on slide trains and is displaceable in the manner of a drawer relative to the loading opening. To fasten the vertical oven door to the slide trains, solid fastening angles are provided, which are also relatively wide on the vertical leg and require considerable constructional depth of the door structure. According to the invention, the constructional depth of the oven door is considerably reduced in that an inherently rigid essentially L-shaped support sheet is provided as bearing part for the oven door and for the slide trains, which is correspondingly rigidified by profiling. <IMAGE>

Patent DE-3131624-A1 (DE)
Title: Grab with controllable movement pattern of the cutting edges of grab shells
Inventor: SCHMIDT ULRICH DR ING
IPC: B66C3/02
Filed: 1981-08-10
Abstract: The invention relates to a grab with controllable movement pattern of the cutting edges of grab shells by a mechanical, hydraulic or other device. The object of the invention, by horizontal guidance of the grab cutting edges close above the base, e.g. of railway wagons, carrying the material or on unpaved storage yards, is to protect the base from wear or prevent its destruction and permit optimum pick-up of residual material. The device inserted between the grab of known type of construction and the supporting member of the lifting appliance produces the horizontal movement of the cutting edges by the adjustment of the height of the closing curve as a function of the shell position as soon as the vertical retaining force is taken up at the supporting member of the lifting appliance. If it is inconvenient to realise the force flow for the height-adjustment movement via the drive of the grab, provision can be made for the use of a follow-up control system. Here, the force for lifting the grab is additionally applied as a function of the position of the grab shells. As long as there is still material to be conveyed at an adequate height, the grab works with a normal arched closing curve. <IMAGE>

Title: Connecting rod with big end bearing cover for reciprocating piston machines
Inventor: DEREK HEINZ
IPC: F16C7/00
Filed: 1982-03-03
Abstract: The subject-matter of the invention is a connecting rod composed of fibre composite material for reciprocating piston machines, which is divided at the connecting rod head and is very slim. The division at the connecting rod head makes possible retrofitting on an undivided, multi-crank crankshaft. The division is achieved by the fact that the fibres loop around force introduction elements which are contained in the big end bearing cover and in the connecting rod. The force introduction elements are connected by clamping screws. The very slim construction is achieved by means of the cross-shaped course of the fibres in the shank of the connecting rod. It is thereby possible to make a substitution for installed metallic connecting rods in reciprocating-piston machines without structural modifications. The existing violin shape of the connecting rod is altered only insignificantly thereby. <IMAGE>

Patent DE-3214794-A1 (DE)
Inventor: SPIES ALFONS DIPL ING
IPC: G01D5/14
Filed: 1982-04-21
Abstract: A magnetic measuring instrument for measuring the relative position of two objects includes a scanning unit which incorporates a magnet positioned to scan a measuring division. The measuring division is provided with alternately magnetically conducting and magnetically non-conducting zones. Measuring signals of high signal quality are generated because the induction generated by the magnet in the measuring division runs only in planes perpendicular to the longitudinal extent of the measuring division (the measuring direction x). Magnetic field sensitive sensor elements in the air gap between the magnet and the measuring division scan the air gap induction to generate position dependent measuring signals.
Patent DE-3217731-A1 (DE)
Title: Method and arrangement for varying the mean output value of a load
Inventor: BEDARD JAMES FREDERICK
IPC: H02M1/08
Filed: 1982-05-12
Abstract: The output value of a load is varied by controlling the time relationship during a random time interval during which the output is being supplied, and thus controlling the mean output value of the load. The zero crossovers (30') of an AC supply oscillation (11a) are determined in order to trigger an interval timer (28) which generates pulses which are applied to an on/off input of the load; the duration of each "on" time interval can be adjusted in order to control the portion of the random time interval during which the load is in the "on" state. <IMAGE>

Title: Radial piston machine, especially radial piston pump
Inventor: BUDECKER LUDWIG
IPC: F04B1/107
Filed: 1982-05-25
Abstract: In the case of a radial piston machine, especially a radial piston pump, an axially displaceable rotor is provided, which is pivotally connected by way of a spring coupling (2), engaging on the one rotor end face, to a connecting shaft (30) located as a coaxial extension of the rotor. The rotor (1) is arranged in the machine housing (20) or in the stator in such a way that on the charging pressure side (13) of the machine a face gap is formed between rotor (1) and housing (20) or stator, through which, in operation of the arrangement, pressure medium from the charging pressure side (13) can be fed to at least one sector area of that rotor end (32) on which the spring coupling (2) does not engage. In this way the rotor (1) is centred by the spring coupling (2) and the pressure from the charging pressure side acting on the sector area of the rotor end (32) in such a way that in an axial direction no metal-to-metal contacts and hence no friction losses occur. The non-contact position of the rotor in an axial direction improves, in particular, the efficiency of radial piston machines of smaller output and reduces the transmission of structure-borne noise. Rotor and stator may be provided as a structural unit and flexibly supported in the machine housing. <IMAGE>

Title: Stacking device for forming a total pile from smaller piles of sheets
Inventor: BAUMANN BERNHARD
IPC: B65H29/00
Filed: 1982-05-26
Abstract: Two smaller piles of sheets are placed on a table (4), each pile of sheets being provided with its own table stop (20a or 20b). The table (4) is moved over total piles (not illustrated in the drawing). The two partial piles situated on the table are then fixed between stops (18a, 19a or 18b, 19b). The table (4) is then withdrawn and the two piles of sheets previously situated on the table (4) are deposited on the total piles. The arrangement allows two total piles to be produced in the same time as was previously required for forming one total pile. In this case, the total piles can be built up, for example, in such a way that one side of the pile is flush with the edge of a pallet and the total piles are otherwise aligned centrally on the associated pallet in each case. Direct further processing of these total piles in machines with pallet feeders is thus possible. <IMAGE>
Patent DE-3226405-A1 (DE)
Title: Machine for the production of frictional heat
Inventor: KOLB SEN ROBERT
IPC: F24J3/00
Filed: 1982-07-15
Abstract: In the machine according to the invention for the production of frictional heat, the aim is substantially to improve the proportion of technical outlay to the result, especially as regards the thermodynamic efficiency, in comparison with the known heat generators. This is achieved according to the invention by the suitable choice of material of the friction bodies which slide against each other under a controllable pressure, one body with high heat conductivity having an optimally smooth, closed and hard sliding surface, while the revolving counter-body has the lowest possible heat conductivity and is provided with a sliding layer preferably consisting of a dense felt of organic or synthetic fibres. In this way, wear of the frictional surfaces could be practically eliminated, as was shown by fatigue tests, the quantity of heat delivered with a very high efficiency obviously being attributable to internal friction in the boundary layers between the frictional surfaces. The useful heat produced is conducted away in an advantageous manner by a medium, e.g. water, flowing through the carrier of the hard slide layer, the relative motion of which is equal to zero. The frictional bodies can be moved relative to each other in a linear or rotary manner.

Patent DE-3229040-A1 (DE)
Title: Infinitely variable gearing
Inventor: MOELLER REINHOLD
IPC: F16H15/38
Filed: 1982-08-04
Abstract: The essential point of this infinitely variable gearing is that a driven, circumferentially grooved input disc (15) and an oppositely arranged output disc (18) (Fig. 1) are provided. Arranged to work between them are transmission wheels (19, 20) adjustable relative to one another. The pivotability of the transmission wheels (19, 20) relative to one another guarantees the widest step-down and step-up possibilities (as the maximum output speed range). The connecting pressure between the three gearing members is produced automatically by the contact pressure clutch. The contact pressure produced is limited within the housing (1, 4, 7) by the thrust bearings (24, 25). Separate individual assembly on and in the housing parts (1, 4, 7) is very simple and, by connecting them together, allows easy final assembly. Also of essential importance is the two-fold split in the power transmission by means of the transmission wheels (19, 20), and the simplicity with which the latter can be operated. <IMAGE>
