Title: Printing machine with stepping motor - has motor rotation monitor detecting rotation shown by number of pulse signals, which are compared with preset number
Inventor: HANAGATA TAKAYOSHI
IPC: B41J19/20
Filed: 1980-09-01
Abstract: The stepping motor provides a relative movement between paper and a printing head. Its rotation magnitude is detected by a monitor. The monitored amount of rotation is compared (21-26) with a number of pulse signals generated by the stepping motor rotation by a preset amount. The comparator generates a fault signal when the amount of the stepping motor rotation differs from the preset value. The rotation monitor pref. contains a photocoupler (15) engaging an edge of a disc, rotating in dependence on the rotation of the stepping motor. The pulse signals may be transmitted by a pulse generator (20), while a counter (21) checks the generated pulse signals. The counted pulses' number is processed in a decoder, generating a signal supplied to the comparator instead of the signal from the counter.

Title: Baling press with actuating device for a sealing door
IPC: B30B9/30
Filed: 1981-03-31
Abstract: The invention relates to a baling press having a pressing plate which operates in a vertical direction and an actuating device for a sealing door which optionally opens or closes an aperture in the press casing. The object of the invention is the further development of a baling press such that a sealing door can be controlled in dependence on the position of the pressing plate. The invention is characterised in that the sealing door takes the form of a vertically movable sealing slide which is connected to a bolt which engages in the path of motion of the pressing plate and can be brought to rest on that side of the pressing plate which is not acted upon by the material to be pressed. This ensures that the sealing door is closed during the operation of the pressing plate. Figure 1 shows a vertical longitudinal cross-section through a baling press with the sealing door in its closed condition. <IMAGE>

Title: Lattice structure for walls, in particular retaining walls, sound-insulation walls or suchlike structures
Inventor: DIFFERENZ FRIEDRICH DIPL ING
IPC: E02D29/02
Filed: 1981-04-13
Abstract: The lattice structure consists partly of frame elements, preferably precast concrete members, and partly of runner elements which rest loosely on the frame elements in the assembly of the structure. The cross-section of the frame-element webs running perpendicularly to the wall plane has a height which is greater than, preferably twice as great as, the height of the frame webs running parallel to the wall plane so that frame elements arranged one behind the other in the assembly of the structure can be interlocked in a positive manner. The frame webs perpendicular to the wall plane have areas of smaller height projecting beyond at least one of the two frame webs parallel to the wall plane. The runner elements (B) rest loosely and interchangeably on these areas of smaller height. In these projecting areas of smaller height, these frame webs can have a stepped offset for holding the runner elements.

Title: Work-pallet magazine for a machining centre
Inventor: BUGGLE GUENTHER
IPC: B23Q7/14
Filed: 1981-04-16
Abstract: In a work-pallet magazine (12) for a machining centre (10) in which the pallet (14) is in a vertical position during the machining, pallet carriers orbit as a chain or a band in a closed orbital path lying in a vertical plane. The transfer of the pallets (14) between magazine (12) and machining centre (10) is effected at a return point of the orbital path, at which the pallet carriers with the pallets (14) are perpendicular and are located in the same plane as the pallet in the machining centre (10). The pallets (14) can therefore be pushed in a simple manner directly from the magazine (12) into the machining centre (10) without the need for a complicated transfer mechanism. Exact angular positioning and securing of the pallet carriers in the change position permit problem-free transfer. <IMAGE>
Patent DE-3120827-A1 (DE)
Title: Film-winding mechanism for cameras
Inventor: TANAKA SHOGO
IPC: G03B17/30
Filed: 1981-05-26
Abstract: In a film-winding mechanism, use is made for the purpose of transmitting the drive from a drive element to a driven element connected to the film-winding spool of a helical (wire-coil) spring which is wound tightly around the drive element in the sense of rotation thereof and is connected to the driven element (Fig. 4). The coupling according to the invention has a constant slip torque which is virtually independent of a coefficient of friction and thus permits soft operation in conjunction with a constant operating force. The difference, which becomes larger, between the film length which can be wound with one revolution onto the film-winding spool, whose circumference increases, and the constant film-feed length prescribed by a film-feed sprocket is absorbed due to the fact that during operation the helical spring is loosened to such an extent by the increasing load that the drive element can rotate freely in it, that is to say no more transmission takes place. Damage to the film is thereby ruled out. Upon completion of the winding operation, the helical spring draws itself tight again; in this way, the film is held tensioned and constant spacings are ensured between the single frames of the film. <IMAGE>

Patent DE-3125882-A1 (DE)
Title: Method of indicating surface defects in materials
Inventor: KLUMPF HELMUT
IPC: G01N21/91
Filed: 1981-07-01
Abstract: According to a method for indicating surface defects in materials, a penetrating agent is applied to the test surface and penetrates defects which are open at the surface. The excess penetrating agent present on the test surface is then removed with water and a penetrating-agent developer is applied (as specified in DIN 54 152). The penetrating agent used is a test liquid composed of 48.00 % by volume of monoethylene glycol, 48.50 % by volume of chemically pure water, 3.50 % by volume of hydrophilic emulsifier and 0.50 % by volume of corrosion inhibitor, allowing for 2,500 g of organic red dye per 100 l of liquid. Up to concentrations of 20 % in the waste water feed, this penetrating agent does not impede the cleaning process, with the result that a water treatment plant is no longer necessary.

Patent DE-3231869-A1 (DE)
Title: Fuel injection nozzle
Inventor: EBLEN EWALD DR
IPC: F02M61/08
Filed: 1982-08-27
Abstract: The invention proposes a fuel injection nozzle for compression-ignition internal combustion engines, in which the valve needle opens outwards and the head of the valve needle together with the hole accommodating it form the annular injection opening. Due to a turned recess in the hole, a cylindrical portion of a certain width is retained, with the result that this width determines the depth of the gap which serves as the annular injection opening between the needle head and the hole. Due to this calibrated overlap, the pressure drop at the annular injection opening is independent of the stroke and largely constant. As a result, coking is avoided, on the one hand, and fuel preparation is adequate even in the case of small injection quantities (idling), on the other hand. <IMAGE>
Patent DE-3231875-A1 (DE)
Title: Floating apparatus with a floating body and a fin drive
Inventor: STOLL MARTIN
IPC: B63H1/36
Filed: 1982-08-27
Abstract: A floating apparatus with a floating body and a fin drive is driven by oscillating movements of the floating body, the oscillating movements being converted into pivoting movements of the fins. To this end, a plate pivotable relative to the floating body is arranged beneath the same, the narrow side of which plate points in the direction of travel and the pivot axis of which as far as possible coincides with the oscillating axis of the floating body. The fins are fastened to the plate or the centreboard at spindles or the like projecting horizontally at the side, and a rigid connection is provided between the floating body and the fins, which rigid connection acts at the side of the pivot mounting and presses the fin down during a downwards movement, while it lifts up the fin during an upwards movement. The oscillating movements of the floating body about its longitudinal axis thus lead to pivoting movements of the fins, which produce a corresponding propulsion.
