Patent DE-3209609-A1 (DE)
Title: Ignition systems for internal combustion engines
Inventor: HUETTINGER MANFRED
IPC: F02P9/00
Filed: 1982-03-17
Abstract: An ignition system having a control signal generator is proposed which, in order to trigger the ignition, reverses an ignition switch in the primary circuit of the ignition system. The control signal generator (10) is to be of the simplest possible design and to be as easy as possible to manufacture and is to interact with a revolving magnet system. For this purpose, the signal generator winding (13) and two iron core rods (14, 15) inserted therein with in each case one section (14b, 15b) are placed in a housing (17) made of insulating material and secured therein by catch projections (19) and guide ribs (22) on the floor (23) of the housing (17) made of insulating material. The control signal generator (10) can be screwed or riveted, with the housing (17) made of insulating material, tight to an armature of a magnet generator: however it can also be arranged on the motor or gearing or in an ignition distributor where it interacts in each case with a revolving magnet system driven by the internal combustion engine. <IMAGE>

Title: Foot lever for motor bike
Inventor: GANZ ERICH
IPC: B62M25/06
Filed: 1982-05-05
Abstract: A foot lever for motor bikes has an actuation lever with which the brake and/or the shift gear can be actuated via an adjustment lever. Actuation and adjustment levers can be pivoted together in relation to a foot rest pedal. The actuation lever and the adjustment lever have in each case a corresponding inner toothing on their common pivot bearing, into which toothing a bushing which spans these two inner toothings and has a corresponding outer toothing can be plugged. As a result, it is possible to change the angular position of actuation lever and adjustment lever in a simple manner by removing the bushing provided with outer toothing, adjusting the lever by one or more tooth divisions and then reinserting the bushing for the purpose of locking. Moreover, this arrangement permits a mirror-inverted use of the same lever structure on both sides of a motor bike.
Patent DE-3223591-A1 (DE)
Title: Control valve, in particular for a hydraulic self-advancing support with a water hydraulic system
Inventor: NAUNDORF PETER ING GRAD
IPC: E21D23/16
Filed: 1982-06-24
Abstract: Control valves, in the housing bore of which at least one slide rod with a slide piston working as a valve-closing body is arranged in a longitudinally displaceable manner, are provided for controlling hydraulic thrust-piston mechanisms on underground self-advancing supports. A problem here is the fact that a control valve of this type is also to work free of leaks, with small control forces and with relatively high flow rates in a water hydraulic system and with a long service life of the seals. The valve therefore has sleeves surrounding the slide rod on both sides of the slide piston. The sleeves are guided in the housing bore while forming a passage and pass over the allocated piston seals upon adjustment of the slide rod into the open position, so that the piston seals are masked against the hydraulic flow.

Title: Roll changing apparatus for disc rolls or roll rings seated as horizontal rolls in a floating arrangement on a rotating shaft part by means of clamping
Inventor: BOEHMER FRIEDHELM
IPC: B21B31/10
Filed: 1982-07-16
Abstract: The intention is to mechanise the changing of floatingly mounted rolls by means of a corresponding changing apparatus and hence to considerably reduce the changing times and the manual work involved. According to Fig. 1, a column (7) is for this purpose arranged to the side of the roll stand (1), perpendicularly to the rolling axis, in a common vertical plane intersecting the longitudinal axes (3, 4) of the shafts. The column has, in two mutually parallel horizontal planes, in each case at least two supporting arms (I, II) offset relative to one another in the circumferential direction at equal angles and designed as supporting-arm rings (8, 9). The supporting arms (I, II) of each supporting-arm ring (8, 9) can be pivoted in alternately with their longitudinal axes towards the roll stand (1) so as to be in alignment with the longitudinal axes (L) of the shafts. The supporting arms of each supporting-arm ring are intended to hold rolls and/or clamping means. The foot of the column (7) is rotatable in a bearing (10) in the foundation (F). When feeding in the columns (7) with replacement rolls, roll changing can be performed simultaneously on several roll stands. <IMAGE>
Patent DE-3233439-A1 (DE)
Title: Process for dephosphorising molten steel
Inventor: SCHIERLOH UWE DR ING
IPC: C21C7/064
Filed: 1982-09-09
Abstract: For some applications, it is of particular importance to obtain steels having especially low phosphorus contents. The present process uses sodium ferrite, prepared by sintering of iron oxides and soda, for dephosphorising the molten steel in the ladle. To produce the sodium ferrite, the resulting, finely granular converter dust can advantageously be used. As a result of using sodium ferrite, the quantity of smoke arising is minimised, as compared with the use of soda, and the ejection of molten steel is prevented. In addition, wear of the refractory lining is greatly reduced.

Title: Circuit arrangement for connecting and disconnecting a supply voltage to a and from a load, respectively
Inventor: VOGELER TORSTEN DIPL ING
IPC: H03K17/30
Filed: 1982-09-28
Abstract: In a circuit arrangement for connecting and disconnecting a supply voltage to a and from a load, respectively, particularly to a and from a microprocessor, respectively, a voltage measuring device (M) is used for measuring the supply voltage and for outputting a control signal in the case where the supply voltage reaches a predetermined first voltage value (U1). The control signal is used for controlling a self-latching output circuit (T1, T2) from the blocked state to a self-latching state. In the self-latching state, this output circuit (T1, T2) forwards the supply voltage to the load; it measures the supply voltage supplied to the load and then passes back to the blocked state when the supply voltage occurs with a predetermined second voltage value (U3) which is below the said first voltage value (U1). <IMAGE>

Title: Device for treating light-sensitive material
Inventor: OHTANI SHINICHI
IPC: G03D3/08
Filed: 1982-11-25
Abstract: A device for the automatic treatment, and especially development, of photographic material is disclosed, which has a transport path, comprising a number of transport rolls, for the material to be treated and at least one tank filled with treatment fluid on this transport path, where some of the transport rolls are located. The level of treatment fluid in the tanks is adjusted such that the transport roll located at the inlet partially dips into the treatment fluid, in such a way that the liquid level is at a height between one quarter and to 0.7 of the radius of this transport roll above the axis of rotation thereof. This avoids deposition of impurities, floating on the surface of the treatment fluid, on the light-sensitive material to be treated, and contamination or spottiness of the surface thereof.

Patent DE-3304793-A1 (DE)
Title: System with wheel-chair and elevator
Inventor: KLEIN HELMUT WERNER
IPC: A61G7/10
Filed: 1983-02-11
Abstract: The invention relates to a system with a wheel-chair and an elevator which permits disabled individuals to move, especially in swimming baths, without the aid of other people and to climb into and out of the pool without help. The wheel-chair is equipped with a pair of main carriers to which a front and rear small wheel pair is allocated. All wheels are jointly movable on each side via a drive connection. The smaller wheels have a slight level offset relative to each other. The belt connection of the wheels serves not only as a common drive connection but simultaneously also as a rolling surface on the ground, so that even relatively small steps can be overcome. In terms of the specific aspect of the suitability for swimming baths, an elevator which can be installed on the pool edge is adapted to suit this wheel-chair. The lifting device of the elevator is merely hydraulically driven, especially when used in swimming baths, so that the pressure water medium has provided an optimum solution in terms of safety and of hygiene. The bearing surface of the elevator can be driven on by the wheel-chair and can be lowered together with the wheel-chair into the water of the swimming pool. This permits the disabled individual to climb in and out of a pool by himself/herself (Fig. 5). <IMAGE>

Title: Process for heat generation
Inventor: RUSSLAND WOLFGANG
IPC: F23N1/00
Filed: 1983-02-15
Abstract: The invention provides a process for heat generation by combustion under elevated pressure. Supplied air and fuel are fed in at elevated pressure. The condensation energy of the flue gases is used. Harmful residues, such as sulphuric acid, can be collected and do not reach the environment. The elevated pressure of the flue gases is used to compress the supply air. The flue gases are further cooled by the pressure reduction. A considerably better use of energy is thus achieved than with conventional combustion processes.

Title: Method for controlling the closing time for internal combustion engines
Inventor: MAYER ULRICH DIPL PHYS DR
IPC: F02P3/045
Filed: 1984-01-26
Abstract: A method for controlling the closing time for internal combustion engines is proposed, in which the primary-side current of an ignition coil (6) is detected by comparators (8, 9) so that an optimum closing angle is obtained by switching an ignition output stage (5) by means of a control algorithm stored in a microcomputer (4). The control takes place as a function of two marks (M1 and M2) of a signal generator wheel (1) which rotates with the crank shaft of the internal combustion engine so that a signal which is dependent on the speed of revolution and angle and influences the control is available to the microcomputer (4) at an input (PO) via a sensor (2) and a switching amplifier (3). In the normal operation state of the internal combustion engine, an ignition time (tz) is fixed between the first reference mark (M1) and ignition point and an opening time (t0) between ignition and closing time of the next period which is made up from a minimum, speed of revolution-dependent opening time, a cylinder-specific control time and a supply voltage-dependent charge time of the ignition coil (6). <IMAGE>

Title: Tandem master cylinder with built-in hydraulic brake booster
Inventor: BURCKHARDT MANFRED DR ING
IPC: B60T8/32
Filed: 1984-02-07
Abstract: In a tandem master cylinder, designed as a stepped cylinder, with hydraulic brake booster for a dual-circuit brake system with brake circuits capable of admitting a static pressure a proportional control valve controlling the pedal force transmission is incorporated into the primary piston of the tandem master cylinder. The primary piston comprises an outer annular piston to which the outlet pressure of the proportional control valve can be admitted, a plunger piston displaceably arranged in the annular piston, to which plunger piston the outlet pressure of the proportional control valve can also be admitted, and a control piston, on which the brake pedal acts, displaceably arranged in a central longitudinal bore of the plunger piston. By way of a reaction space, which is connected to the primary outlet pressure chamber of the tandem master cylinder, the pressure prevailing in the latter acts on this control piston. In this way a very sensitive feedback is achieved on the brake pedal regarding the functional state of the brake system. The tandem master cylinder is particularly suitable for a brake system which is equipped with an antilock system functioning on the outflow principle.
