Title: Trunnion bearing for a cradle support of a weapon with a barrel
Inventor: BARTELS WOLFGANG
IPC: F41A27/08
Filed: 1988-10-28
Abstract: In order to ensure the use of smooth-barrel technology in battle tanks which are equipped with weapon systems for rifled projectiles, and thus to enhance the firing performance, it is provided for a trunnion bearing to be provided for the respective tank turret, by means of which, for example, a 105 mm weapon system provided with rifling can be replaced by a 120 mm smooth-barrelled weapon system without any additional means or, alternatively, use of either the 120 mm weapon system or the 105 mm weapon system is possible. In this case, it is intended to take account of the different firing heights of weapon barrels' different calibre and adequate free movement in the armoured vehicle during rotation of the turret. The invention provides that the common centre axis (10) of the trunnion (4) of the radial bearing which holds the respective trunnion (4), of the axial bearing and of the threaded ring (9) with respect to the axis of symmetry (11) of the external contour (12) of the associated bearing housing (5.1) is arranged offset by the distance (a) in height. With the same turret mouth machining of armoured vehicles of different size, the bearing housings (5.1) can be interchanged with one another in a simple manner, as a result of which height adjustment of the trunnion axis (10) and, coupled thereto, of the barrel bore axis, is possible without additional means. <IMAGE>

Title: Lock for one-handed operation
Inventor: SCHIEF ALFRED DIPL PHYS
IPC: E05B43/00
Filed: 1988-11-19
Abstract: Doors are in many cases provided with a lock which has a latch and which can be opened from one side only by means of a key. When the opening of the door takes place towards the opening person and counter to the force of an automatic door closer, two hands are required for the opening operation. The invention avoids this disadvantage by equipping the lock or the striking plate with means, preferably of an electrical and electromechanical type, which ensure that the latch of the lock remains released during a predetermined period of time after the actuation of the key. During this period of time, the opening person can withdraw the key and, with the same hand, pull the door open by the door knob. A sound or light source emits a signal, detectable by the opening person, as long as the latch is released.

Title: Method for increasing the resolution of an A/D converter and device for carrying out the method
Inventor: BRENNINGER HEINRICH
IPC: H03M1/56
Filed: 1989-01-20
Abstract: A method is described, with the aid of which the resolution of an A/D converter can be increased which converts an analog input signal value into a corresponding digital output signal value. The digital output signal value is determined by comparing the analog input signal value to be converted with an analog stair-step signal, which passes through a predetermined value range during a conversion cycle, with predetermined step height S in which each step corresponds to one digital value. The input signal value is compared with the analog stair-step signal in n conversion cycles and the input signal value is changed in the same direction by S/n before each repetition of the conversion cycle. In each conversion cycle, the digital values which, when it is found that the compared signals correspond, in each case correspond to the step of the stair-step signal reached at that time, are added up to form a digital sum. The digital sum reached after n conversion cycles is taken as the digital output signal corresponding to the input signal value. <IMAGE>

Title: Pocket disc engine as internal combustion engine
Inventor: HELLMUTH HANS-JOCHEM
IPC: F01C11/00
Filed: 1989-03-21
Abstract: All spark ignition and diesel engines have large oscillating masses, high friction resistances and do not run free of vibration. Due to the unfavourable form of the ignition space Wankel engines have incomplete combustion: the expansion force is converted into rotary motion by way of mechanical deflection. The new combustion engine is designed to have high efficiency and vibration-free running for a low weight and space requirement. It is proposed to convert the expansion force directly into rotary motion. A screw-type compressor (3) takes in an air-fuel mixture and compresses it. In the stroke the ignition space (7), by way of a port control shaft (6), is charged with the compressed mixture. The port control shaft (6) closes off the ignition space (7) from behind. The mixture is ignited. The sealing flap (8) opens the ignition space (7) towards the front and the expanding gas sets the pocket disc connected to the main shaft (15) in rotary motion. The compressor (3) and the port control shaft (6) are directly driven by the main shaft (15). The pocket disc engine can be used where internal combustion engines have hitherto been used. <IMAGE>
