Title: Oil-cooled, multi-part trunk piston for internal combustion engines
Inventor: GENTSCHEFF JORDAN DIPL ING
IPC: F02F3/00
Filed: 1987-03-07
Abstract: In known trunk pistons, cooling oil fed into a central piston cooling chamber by way of the connecting rod is brought to the inside of the piston head solely by the shaker action of the moving piston. The shaker action has the disadvantage of being dependent on the speed of the engine. Due to the short distance y of the outlet orifice (27) of the central oil feed line (20) from an elevation (15), arranged on the underside of the piston head (5), in conjunction with a special curvature of that part (28) of the contour of the piston head inner side (23) which lies over the outlet orifice (27), a turbulent boundary layer flow is achieved on the piston head inner side (23) and, due to the increased heat transfer coefficient  alpha , an improved cooling independent of the engine speed is achieved. The invention can be advantageously used in all oil-cooled trunk pistons, but especially in internal combustion engines with spontaneous ignition subjected to high temperatures. <IMAGE>

IPC: H01R11/20
Filed: 1987-03-25
Abstract: The invention of a cable-branching terminal and fully insulated branch of a cable from a main cable bonded under voltage has the purpose of improving a single-phase, fully insulated cable-branching terminal for providing a single-phase or multi-phase branch which, without the use of casting-resin sleeves, is designed to be quick, durable and protected against external voltage shorts. The known single-phase branching terminal has in this case an elongate insulating housing in which there is centrally connected a contact rail which forms a clamping channel with a pressing screw for fixing the branch conductor, and a threaded bore for a milling screw for bonding the main conductor, which is led between the insulating housing and a closure part, likewise consisting of electrically insulating plastic. According to the invention, the individual branching terminals, if appropriate for providing a multi-phase branch arranged next to one another in a tight circle, are in each case sheathed by shrink films and shrink tubes shrink-fitted under the effect of heat, the overlapping region of the respective shrink film and shrink tubes on the arrangement comprising branching terminal and main or branch conductor extending in each case until over the outer conductor section. There are provided in this case tubular and shell-like stubs or stub parts, which permit a continuous transmission to the insulating housing or to the closure part.

Title: Asymmetric thyristor
Inventor: VOSS PETER DR
IPC: H03K17/04
Filed: 1987-09-24
Abstract: The blocking properties of asymmetric thyristors which block on one side are improved by means of shortcircuits on the anode side and cathode side. However, these shortcircuits on both sides can lead to recovery failure. In order to avoid this and to ensure both favourable turn-on propagation and a short recovery time, it is proposed to connect a diode (17), for example a Schottky diode, and a capacitor (16) in parallel between the gate electrode (13) and the cathode electrode (7) of the asymmetric thyristor. This results in it being possible to reduce the shunt effect of the diode (17) to a level which is determined by the desired, permissible off-state currents. <IMAGE>

Patent DE-3809199-A1 (DE)
Title: Method for determining the repetitive time of synchronization
Inventor: SAUPER ECKHARD DIPL ING
IPC: G01R29/18
Filed: 1988-03-18
Abstract: In order to be able properly to connect together two three-phase power systems or to be able to connect a generator to the three-phase power system, there must be synchronism. This is given when the voltages, the frequencies, the phase angle and the phase sequence of the voltages are equal. Since the frequencies always have a slight difference, a beat occurs. Thus, synchronization is in each case only possible at a certain time. The known synchronization methods and devices have the disadvantage that switching does not occur optimally at the synchronization time. The method according to the invention is based on a cyclic digital detection of the duration of the period (F0, F1) and the phase shift (P0, P1) between two square wave signals (1, 2) which have the same phase as the alternating voltages. In each cycle (8), a counter (23) counts from one to the next but one edge of one square wave signal (1), then from this edge to the next equivalent edge of the other square wave signal (2). Then counting takes place from this edge to the next but one edge of this square wave signal (2) and lastly to the next equivalent edge of one square wave signal (1). The next synchronization time is calculated by means of a program in the process computer from the stored counts. The novel method can be used for switching more accurately at the synchronization time when the switching delay times are included. <IMAGE>

Title: Hospital bed with adjustable backrest
IPC: A61G7/002
Filed: 1988-04-13
Abstract: A conventional hospital bed is provided with a backrest which is adjustable in the range from 0@ to about 70@ about a horizontal axis fixed on the frame side. In order to facilitate flexing of the mattress lying on it during raising of the backrest, that side of the mattress which faces the horizontal surface of the hospital bed is slotted over the entire width. Due to the geometrical conditions, however, the top part of the mattress slides beyond the outer front edge of the backrest on pivoting of the backrest, so that this projecting part is no longer supported and the mattress is not optimally useable. The invention provides that the backrest (2) be of two-part design and comprise a support (6) and a bearing part (7). At the same time, the support (6) is connected to the bearing part (7) connected to the axis (4). Furthermore, there is a gear which is used to increase the distance of the support (6) from the axis (4) with increasing pivot angle of the backrest (2). As a result, the backrest is automatically extended on pivoting and adapted to the length of the mattress part that has likewise been pivoted. On pivoting the backrest back, its length is automatically shortened, so that the original dimensions are obtained. The horizontal surface predetermined by the mattress is therefore optimally utilised in any lying position. <IMAGE>
