Title: Intake system for a multicylinder, mixture-compressing internal combustion engine
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F02N19/06
Filed: 1986-06-28
Abstract: An intake system for a multicylinder, mixture-compressing internal combustion engine with a first intake line (2) of relatively small flow cross-section and with a second intake line (3) of relatively large flow cross-section is described. Both intake lines have throttle devices (4, 5) for closure of their flow cross-sections as a function of the operating state. The first intake line (2), opened only in the lower load range, also has a fuel feed device (6). The two intake lines are also connected by way of intake pipe sections (9, 13) opening into one another to an inlet valve (10) assigned to each of the individual cylinders of the internal combustion engine respectively. The first intake pipe section (9) connected to the first intake line (2) is intended to open into the intake pipe section (13), connected to the second intake line (3) at a point (15) at which an injector action, generated in flowing through the second intake pipe section, is exerted on the first intake pipe section in order to ensure an adequate mixture delivery rate at all times. <IMAGE>

Patent DE-3700388-A1 (DE)
Title: Type of design for building and converting bicycles for more road safety, utility and convenience
Inventor: SCHELOWSKY MICHAEL
IPC: B62K3/00
Filed: 1987-01-08
Abstract: By converting and adding to conventional bicycles, an increase in road safety, utility and riding convenience can be achieved through having the normally steered front wheel trailing as a rear wheel with a handlebar on the rear forked fitting. The fixed wheel becomes the front wheel, with chain wheels with cranks connected on both sides via extremely short chains. This allows the rider's seat to be positioned about 40 cm lower. With this design, the centre of mass of the rider load is located considerably more advantageously, with sufficient leg reach for quickly supporting oneself when in danger of falling and for preventing accidents caused by steering errors at the otherwise usual front wheel. The bicycle is drawn by the fixed driven front wheel with directional stability. It can be loaded with a baggage container without impairing its steerability. The now empty bottom bracket shell can be used to couple two bicycles side by side to form a four-wheeled vehicle with two additional linkage points at the height of the riders. This novel convenience for single-seater and now two-seater human-powered vehicles is supplemented by possibilities for fastening protective coverings. The structural components proposed here are to be considered as an assembly kit for converting conventional bicycles, as well as for new designs making use of solar cells in conjunction with streamlined bodies on human-powered utility vehicles.

Title: Door suspension, in particular in a shower partitioning
Inventor: BRENDEL AXEL
IPC: E05D11/10
Filed: 1987-02-24
Abstract: The invention relates to a door suspension, in particular in a shower partitioning, for a leaf door suspended such that it can pivot about a vertical axis.

In order that unevennesses in the wall and other tolerances can be compensated for, a latching portion (7), fastened on the door profile of the leaf door, can be adjusted in the circumferential direction through a restricted pivot-angle in order to make possible an accurate alignment of the door leaf (14) with respect to a shower-tray border. <IMAGE>
Patent DE-3707787-A1 (DE)
Title: Endoscope
Inventor: GRUENDLER PATRIK DR MED
IPC: G02B23/24
Filed: 1987-03-11
Abstract: An endoscope having a bendable extruded member (6) is improved by arranging that the extruded member (6) consists of a multiplicity of segments (1) which are lined up with one another, connected to one another by joints (3, 4) and surrounded by a hose envelope (5), and that each joint (3, 4) is assigned an electronically controllable actuator (7, 8). The storable information on angular position and the corresponding positioning movements pass through the joints (3, 4) one after the other in the direction opposite to the direction of advance of the endoscope. The resulting snake-like movement facilitates the insertion of the endoscope into tightly wound hollow passages. The joints (3, 4) can be constructed as hollow spherical sections which can be snapped together. The actuators (7, 8) are bellows which act in opposition to one another and are subjected to a controllable pressure, for example by heating (9) an easily evaporable liquid contained therein. <IMAGE>

Title: Device for sealing off an air chamber
Inventor: TROLLMANN CONRAD
IPC: F16J15/32

Abstract: 1. Apparatus for the reproduction of data which can be read contactlessly from a recording medium by means of an optical scanning device. 
<??>2.1 Such apparatuses are equipped with a focus control circuit, in order to focus the light beam scanning the data onto the recording medium, and with a track control circuit, in order to be able to guide the light beam on the data tracks. The control amplifiers (FR, TR) of the two control circuits are, however, affected by an off-set voltage, which varies with the temperature and ageing of the control amplifiers. 
<??>2.2 In order to compensate the off-set voltage automatically, measuring pulses of alternating polarity are impressed on the control circuit and the times which elapse until the pulse responses exceed a predeterminable threshold value are stored and compared with one another. An off-set compensation voltage available at the input of the control amplifier (FR, TR) is varied until the times compared with one another are the same for two successive pulse responses.

Filed: 1987-09-30
Abstract: In the case of CD players having a memory with A memory locations for storing the tracks recorded on a CD, it is possible that there are more tracks C on the CD than there are memory locations A provided for this in the CD player. In order to make better use of the memory space in such cases and in order to keep the access times to the individual tracks low, instead of storing the starting times of the individual tracks, in some cases or in all cases the difference between the starting times of each two successive tracks is stored. The more tracks are recorded on a loaded CD, the better the memory space is used and the more the access times are reduced.
