Title: Brake pressure modulator
Inventor: KLEIN HANS-CHRISTOF
IPC: F16D65/14
Filed: 1987-06-05
Abstract: The brake pressure modulator (36) has a mechanism (1) which is placed between its actuator (3) and its volume receiver (35) and the transmission ratio of which varies as a function of the stroke of the displacer or plunger (2) in the volume receiver (35). In this arrangement, the mechanism is designed in such a way that the (hydraulic) forces urging the displacer or plunger (2) in the direction of extension remain in equilibrium with a constant design actuating force of the actuator (3) when, after a predetermined maximum pressure in the volume receiver (35) has been reached, the displacer or plunger (2) is extended, with the closure of the separating valve (5). To control the plunger strokes, slight changes or a sufficient lowering of the actuating force of the actuator (3) are then sufficient. <IMAGE>

Patent DE-3801399-A1 (DE)
Inventor: WEISS HANS DIPL ING
IPC: H02M3/156
Filed: 1988-01-20
Abstract: A power supply is proposed for producing a regulated DC voltage from a mains AC voltage, which power supply has a capacitor (18), which exhibits the output DC voltage (Ua) and can be charged via a rectifier arrangement (11), and a semiconductor switch, which bridges the output of the rectifier arrangement (11) and can be controlled as a function of a predeterminable nominal value (U2) and the actual value of the output voltage (Ua). A control device (16, 17, 19), which moves the semiconductor switch into the conducting state in synchronism with the mains AC voltage or with the rectified voltage half-cycles derived therefrom and moves the semiconductor switch into the blocking state if the actual value is less than the predeterminable nominal value (U2), is connected upstream of the semiconductor switch, at least one resistor (8, 9), preventing a current overload of the rectifier arrangement (11), being provided between the mains connection and the semiconductor switch. Since only a very low voltage is in each case applied to the semiconductor switch (13) at the times when it switches, the power loss and the radio interference are kept small. <IMAGE>

Title: Method of adapting a ventilation system for refrigerated containers of different height stacked one above the other
Inventor: KOBABE JOHANNES
IPC: B63J2/12
Filed: 1988-06-30
Abstract: The present invention relates to a method of adapting a ventilation system for refrigerated containers of different height stacked one above the other on transport ships to air ducts designed as a double duct for supply and return air, with connections which are connected to corresponding connections for supply and return air which are each arranged on one container side. In the prior art there have been problems time after time with the stacking of containers and their attachment to ventilation systems, since containers have different dimensions, in particular a height of 8' and 8'6". The invention provides a remedy by an extension piece being fitted or removed in the centre area of the air duct, and by the connections being reset in a precisely fitting manner (Fig. 3). <IMAGE>
Patent DE-3822824-A1 (DE)
Inventor: ALMES HORST-DIETER
IPC: B65G15/02
Filed: 1988-07-06
Abstract: The radially outermost marginal portion of a flat washer-like or disc-shaped belt in a belt conveyor is confined in an arcuate slot of a reinforcing member which has (a) a bead surrounding the peripheral surface of the marginal portion, and (b) two lips each of which extends radially inwardly of the bead and overlies one of the two lateral surfaces of the marginal portion. The lips are fastened to the belt, and the bead has a convex external surface which is guided by pairs of rolling elements at locations radially outwardly of fasteners which secure the lips to the belt. This reduces the likelihood of spreading of the open inner end of the slot and resulting rapid destruction of the reinforcing member.
Patent DE-3829905-A1 (DE)
Title: Method for detecting the position of an axle (shaft)
Inventor: GROHMANN THOMAS DIPL ING
IPC: G01D5/245
Filed: 1988-09-02
Abstract: The method describes the detection of the position of a rotary or linear axle in the case of axle drive systems in which an arbitrary position pulse encoder is provided. The axle movement can comprise a multiple of 360@ in this case. For this purpose, the information of the arbitrary position pulse encoder (AW) is fed in the form of equidistant position pulses to a counter (Z) which sums up these position pulses as far as an absolute value (Iabs) at which both the axle (A) and the position pulse encoder (AW) have reached their zero position. The pulses are restricted to the range of +/-180@ by a downstream modular counter (MZ). A respective modular jump (discontinuity) is sent to a register (R2), and the respective angular position inside a modular region is sent to a further register (R3), with the result that the number of revolutions and the current angular position of the axle are available at any time. The method can be used without expensive modifications in existing position detecting devices and positioning controls. <IMAGE>

Title: Saddle
Inventor: BLUEMCKE SIGURD PROF
IPC: B68C1/16
Filed: 1989-01-26
Abstract: In riding saddles, the problem exists that the saddle must fit both the rider and the horse as well as possible. In this connection, the bearing surface is to distribute the weight of the rider as uniformly as possible over as large an area as possible, a good contact having to exist, finally, between rider and horse. In an adjustable saddle with a saddle-tree and saddle-tree bars fastened adjustably thereon, it is proposed to connect the saddle-tree bars in each case in their front regions, in each case via an adaptable front fastening for adapting the spacing between saddle-tree and saddle-tree bars, essentially rigidly to locating ends of the saddle-tree and at a rear fastening point to the saddle-tree via a joint which is designed in such a manner that at the fastening points at least a tipping and thus a twisting of the elastically designed saddle-tree bars about their longitudinal axes is made possible.
