Inventor: WESSA THEO
IPC: F25C5/04

Abstract: A device for comminuting small ice bodies includes a housing without top and bottom walls in which a horizontally extending shaft is rotatably mounted. Disks forming beater knives are mounted on the shaft and counterknives in the form of cross-shaped breaking members are attached to the housing. Groups of adjacent disks define chambers in such a way that each chamber receives exactly one ice body. The chambers are arranged distributed over the circumference of the disks and along the length of the shaft in such a way that only a single ice body is comminuted at a given time. This reduces the power required for driving the shaft to a minimum.

Abstract: A phased array antenna system Includes a plurality of active radiating antenna elements each of which is driven by and each of which drives a transceiver module located closely adjacent thereto. Each transceiver module includes a high-power pulse signal-transmitting amplifier powered by a high-capacitance, low current, a dc rectifier system to minimize charging currents and provide very high pulse currents, and a low-noise amplifier for amplifying the received signal. The modules further include a transmit/receive switch, phase adjusting circuits in the input to the high-power signal-transmitting amplifier and in the output to the low-noise signal-receiving amplifier for normalizing the signal phase, and amplitude limiting means in the input of the low-noise signal receiving amplifier for protecting the low-noise amplifier during the transmit mode. The transceiver module utilizes microstrip line technology to provide tuned circuit elements, is compact in size and low in cost, and permits an improvement in noise, gain, and radiated power characteristics to be realized in phased array radar systems.

Abstract: A system is described for controlling an electromagnetic clutch for a motor vehicle at starting of the motor vehicle. Means (44, 45) determines when the clutch slips and engine speed does not change, and produces a stall signal representing a stall condition. A means (47) provides a reference clutch current in accordance with opening degree of a throttle valve of the engine at the stall condition. The actual clutch current at the stall condition is compared by a comparator means (48) with the reference clutch current, and a current correction setting section (49), controls a clutch current correcting section (42) to correct the clutch change to take account of the disparity between the theoretical and actual engine and clutch operating conditions.

Abstract: Method and apparatus for optimizing the operational state of a system employing iterative steps that approximately follow a projective scaling trajectory or an affine scaling trajectory, or curve (41, 35, 34, 33,) in computing from its present state, x  o  to a next state xi toward the optimum state. The movement is made in a transformed space where the present (transformed) state of the system is at the center of the space (41), and the curve approximation is in the form of a power series in the step size. The process thus develops a sequence of tentative states xi, x 2 , x n .... It halts when a selected suitable stopping criterion is satisfied, and assigns the most recent tentative state as the optimized operating state of the system (28).

Abstract: A pressure switch has a plunger, axially displaceable by the pressure being measured, which enables a contact pin of a microswitch to be actuated. Between the plunger and the contact pin there is arranged a rocker. The microswitch is fastened to the housing of the pressure switch so as to be displaceable in the main extension direction of the rocker.

Abstract: In the case of sound insulating enclosures for air-cooled internal combustion engines it is necessary to ventilate the engine intensively in order to prevent a build-up of heat inside the sound insulating enclosure. If the ventilation is not adequate, premature failure of the internal combustion engine can occur. In the case of sound insulating enclosures for air-cooled internal combustion engines of this type the internal ventilation is to be improved so that no restriction in performance has to be made compared to a non- encapsulated engine in order to prevent temperature-related failures in the case of temperature-critical components. This object is achieved according to the invention in that two outlet ducts (3a, 3b) are provided and the cooling air in the air duct (4) is divided into a main flow (5) to the oil cooler (1) and into two secondary flows (6, 10) for direct cooling of the internal combustion engine. <IMAGE>

Abstract: A briquetting machine, primarily intended for briquetting fibrous plant material, includes a pair of rotatable wheels 10, 11. Each wheel has die means 60, 61 towards its outer periphery and the die means define a circular row of pockets in which the material is received and compressed. During rotation of the wheels 10, 11 come together to define a nip between the wheels. 
     To provide for a varying volume of feed of material the wheels are relatively movable to vary the size of the pockets. Furthermore the die means include male and female overlapping dies 60, 61. In the bases of the dies are located ejector members 50 which are urged outwards to eject compacted briquettes from the dies. 
     To compress the material prior to entry into the dies there may be a precompression channel 74 which converges towards its outlet end, opposite converging walls of the channels being formed of compression members 75 which move towards one another and towards the outlet end.

Abstract: The rotary drive device for the sleeve or the work holder of an erosion machine has two electric motors (8a, 8b) which each drive, for example, the sleeve (2) in a rotary movement via a transmission (6a, 6b) and gears (5a, 5b, 7a, 7b, 4). So that any backlash in the transmission and the gears is neutralised and the elasticity of the drive line is compensated, the two electric motors always run in different directions or at different rates. The entire drive line is thus always under a certain preloading, which permits accurate positioning with simple and inexpensive drive elements. <IMAGE>

Abstract: In cases where a first communication control unit locks a second communication control unit to communicate with the second unit, the first unit stores a data representing a time remaining until the locking of the second unit is released. In these cases, the second unit stores a data representing an address of the first unit as a lock address corresponding to an address of a unit which locks the second unit. In cases where a third communication control unit tries to communicate with the second unit and fails the communication with the second unit, the third unit connects with the second unit and reads out the data representative of the lock address from the second unit, and then the third unit connects with the first unit in response to the lock address and reads out the data representative of the lock remaining time from the first unit. The third unit retries to communicate with the second unit after the lock remaining time elapses.
