Patent DE-2545102-A1 (DE)
Title: Impression printing unit for credit cards - uses two interreacting substances to form initially colourless ink for printing
IPC: B41L47/44
Filed: 1975-10-08
Abstract: The printing unit esp. for use with credit cards with raised printing surfaces (40) uses two substances which react with one another to form the printing ink. At least one substance is transferred from the raised type (40) on the card to the surface of a web (24) of e. g. paper. If the type only transfers one substance, the other is found on the paper web. However the substance or substances transferred from the card type are colourless. The card may be inserted through an inlet (12) over a dispenser (42) for the ink substance. It is then printed on and passes out through an outlet (14) over a wiper (44) which cleans the surface of the card.

Title: Continuous moulding of metal powders - using induction heating coil which moves over the mould operating to a program depending on the sintering temp.
Inventor: GERDAU HERBERT
IPC: B22F3/00
Filed: 1975-11-13
Abstract: Rods and shaped parts are produced from a mxit. of metal powders, which are electrically conducting, by inductive sintering. A refractory ceramic mould is filled with the powder mixt. the mould being located on a rotating table, and an induction coil is moved over the mould contg. the powders, using a fixed-cycle operation in which the cycle depends on the sintering temp. the time required to heat the respective powder combination and on the thickness of the final rod. Pref. the mould is filled automatically. The mixt. is sintered by moving an induction coil over the open mould and the sintered rod is removed manually while a new mould is filled simultaneously with the powder mixt. To avoid oxidn. of the powder mixt. during sintering the mould is rinsed with an inert or slightly reducing gas using the same fixed-cycle operation. The rods and shaped parts are suitable for welding and brazing and esp. for prodn. of wear resitant coatings. The prodn. is continuous and suitable for powder combinations contg. WC and B nitride. Sinter temps. are controlled.

Title: Sampling mechanism for bulk material stream - has reversible transporter delivering to processing unit and back again
Inventor: TEUTENBERG JOSEF
IPC: G01N1/20
Filed: 1976-02-07
Abstract: The mechanism takes and processes samples from a stream of material in bulk, having a sampler working to and fro cross the stream and supplying a transporter delivering to the processing unit. The transporter (5) is reversible, so as both to deliver material to the processing unit (6) and back into the stream (2) again. The sampler can be a narrow funnel moving to and fro underneath the inlet (1a) for the material, coupled via a rotary joint (9) to the transporter, and slewing to and fro on a vertical axis (3). Slewing movement of the funnel can be synchronised with the direction of movement of the transporter, so that the sample is always taken from the desired cross-section of the material stream.

Title: Separator for adjacent cavities - using diaphragm in conjunction with clack type valve
Inventor: WURZER LOTHAR DR
IPC: F16K7/16
Filed: 1976-02-14
Abstract: The diaphragm can be of elastic or flexible material such as rubber or a synthetic material. It is fixed between the upper and lower parts of a chamber. In the middle of the chamber is a blocking piece mounted obliquely and pivoting like a clack type valve between upper and lower levels. The diaphragm is shaped so as to cooperate with the clack type valve and to deform according to the values of pressure applied to the assembly. The assembly gives better sealing between the two parts of the chamber and, is conjunction with the blocking piece, finer control.

Title: Motor car telescopic shock absorber - has metal wire ring pressed into annular groove on piston rod pin
Inventor: SCHMIDT RUDOLF
IPC: B23P11/00
Filed: 1976-03-19
Abstract: Telescopic shock-absorber, esp. for a motor car provides an improved way for joining the piston to the piston rod in order to avoid the danger of cracking in the ring head. This is achieved by forming the bead using a metal wire ring (9) which is pressed into an annular groove (6) on the piston rod'> pin (3). In this way the deformed ring is supported on the one hand on a shoulder turned away from the piston and on the other hand on a leading surface (10) of the piston (1) itself. The endless wire is fed to a combined tool which both bends the metal part and also forms the ring bead.

Title: Treatment of leather in water immiscible organic solvents - with addn. of pickling and tanning chemicals in aq. soln.
Inventor: GRAF HANS DIETER ING GRAD
IPC: C14C3/02
Filed: 1976-06-16
Abstract: Present patent describes a process for prodn. of leather in which the treatment chemicals used are dispersed in a water-immiscible organic solvent, which avoids prodn. of ecologically harmful effluent waters. Process is now improved by carrying out the pickling and tanning in a water-insoluble organic solvent and introducing the chemicals used in the form aq. solns, such that the amt. of water used is 30% of the wt. of the pelts. In the parent specification, the pickling and tanning chemicals are added directly to the pelts with chloro- or fluorohydrocarbon solvents e.g. in the appts. used for defatting the pelts. The presence process now allows use of all types of industrial appts. for operating with water-immiscible solvents, including programmed and automatic metering machines. The preformed chemical solns. can be metered in more quickly and disperse rapidly, giving reduced processing times.

Title: Protection circuit for power switching - guards against short circuits or overloads by sensing excessive current and blocking circuit output through AND=circuit
Inventor: LAU WALDEMAR ING GRAD
IPC: H02H9/02
Filed: 1976-09-08
Abstract: In the protection circuit, an AND circuit, an output stage, a current limiter and an overload sensor are inserted between the input and output. A delay line (6) is inserted between the AND circuit (2) and the output stage (9). A feed-back circuit is connected to the overload sensor (12) output, and is further connected through a threshold switch (11) to the AND circuit (2) blocking input, so that in case of a short-circuit or overload the overload sensor (12) detects the increased current and blocks the AND circuit through the threshold switch (11). Output (13) of the power switching circuit is blocked after the delay line (6) delay time (t2). Blocking of AND circuit (2) is thus removed, and after reclosing delay time (t1) the circuit output (13) is again released.

Title: Lathe chuck for automatic or manual operation - has pinion and bevel gear with tooth protection on ratchet mechanism
Inventor: BECKER WOLFGANG
IPC: B23B31/28
Filed: 1977-03-01
Abstract: The lathe chuck is optionally operated automatically, hydraulically, pneumatically or be electricity, or manually. This facilitates work of operator even on one off component machining. The possibility of a chuck key being thrown out of chuck and causing damage or injury on chuck rotation is eliminated. A double bevel gear wheel (6) has its teeth (10) projecting at the rear of the chuck body (1). This gear wheel engages with the driving pinion (11) of the automatic clamping arrangement (7). The centre of the driving pinion (11) has a spring loaded ratchet pin (13). A torque limiting mechanism with an elliptical plate (19), protects the gear teeth if, for example, a tooth meets another tooth on engaging directly, for protection of teeth against fracture.

Title: Image scanning using triple reflector - inserted at optical beam input so that deviation from null position effects image point shift
Inventor: MENKE JOSEF F DIPL ING
IPC: G02B26/12
Filed: 1977-03-28
Abstract: An optical scanning process is for spectrally-independent image scanning. A triple-reflector is inserted at the optical beam input so that its deviation from the null position effects an image point shift. This process permits a large image angle to be used. The process is realised in an esp. simple manner by an arrangement in which several mirrors are mounted on a disc rotating at right angles to the optical axis. Several triple-reflectors can be installed on a disc rotating about an axis in parallel with the optical axis. Triple prisms can be used instead of reflectors.
