Title: Diaphragm-controlled two-stroke engine with circular, elliptical or slotted hole diaphragm shape
Inventor: KARRENBERG JUERGEN
IPC: F01L3/20
Filed: 1993-02-17
Abstract: The invention contains a diaphragm for inlet control in two-stroke engines which, in contrast to the rectangular designs hitherto known, is of circular or elliptical design or in the shape of a slotted hole. The aim of this invention is to avoid the main disadvantages of the existing design, viz. the high flow resistance and the relatively small cross-sections. Improvement of the flow resistance is achieved by the forms described, which each contain an internal counter-taper. The mixture is thereby precisely controlled without a break. The geometrically determined form results in trapezoidal apertures which, in contrast to the existing rectangular apertures, produce a larger cross-section. Two-stroke engines with very high power output or with a large displacement which are dependent on large inlet cross-sections, are a possible sphere of application.

Title: Method and device for the piecing of an open-end spinning apparatus
Inventor: THIERRON WOLFGANG
IPC: D01H4/50
Filed: 1993-06-28
Abstract: The present invention relates to a method for the piecing of an open-end spinning apparatus. Before the piecing operation commences, the desired run-up curve and the acceleration curve, corresponding to this run-up curve, of the fibre-feed device (110) are fixed for the fibre stream to be supplied to the fibre-collecting surface (136). During piecing, the fibre-feed device (110) is switched on and is driven according to the fixed acceleration curve. The fibre stream produced thereby is deflected on its way between the fibre-feed device (110) and a fibre-collecting surface (136) and is discharged. The respective actual values of the acceleration curve of the fibre-feed device (110) are determined thereby and, as a function of the attainment of a predetermined desired value, the fibre stream is supplied once again to the fibre-collecting surface (136), before the fibre stream initiated by switching on the fibre-feed device (110) has reached its full intensity. Synchronously with this, a thread (20) is returned to the fibre-collecting surface (136) and then, with fibres being tied in, is drawn off again continuously from the fibre-collecting surface (136). To carry out this method, the fibre-feed device (110) is assigned a drive device (115), the acceleration of which can be controlled by a control device (3), by means of which a deflecting device for deflecting the fibre stream on its way between the fibre-feed device (110) and ...

Title: Ballpoint pen with music chip and loudspeaker
IPC: B43K29/00
Filed: 1993-07-14
Abstract: At present, there are only greetings cards which play a tune while the card is folded open. The problem is to incorporate a music chip into a ballpoint pen, which music chip plays a tune (for example an advertising jingle) when the push-button is actuated and switches off after a certain time. The advantage of the ballpoint pen resides in the fact that a tune is played when the push-button is actuated. In order to permit the playing of the tune when the push-button (17) is actuated, a second protrusion (6) is formed on the refill, this pressing on a metal strip (11) and so permitting the flow of electrical current from the battery (12) to the contact breaker (10). In order to permit the interruption of the tune after a predetermined time, a contact breaker (10) is introduced between the battery (12) and the music chip (9), this interrupting the flow of current at a particular temperature. The ballpoint pen is suitable as an advertising medium because of the recordable music chip. <IMAGE>

Title: Resonant circuit
Inventor: WANG ZHIGONG DR
IPC: H03B5/18
Filed: 1993-09-16
Abstract: A resonant circuit (1) has two amplifier stages (22, 23). The capacitances of the resonant circuit are formed by the components (15, 16, 19, 25, 26, 27) of the amplifier stages (22, 23). The inductances of the resonant circuit are formed by two inductances (12, 13) which are in each case connected to the inputs of the amplifier stages (22, 23), are connected to one another by their other ends and are connected to a supply voltage. The amplifier stages (22, 23) are coupled to one another capacitively via a capacitor (31) and neutrally compensated via transistors (38, 39). Symmetrically connecting both ends of the inductances (12, 13) to the amplifier stages (22, 23) results in a completely balanced configuration of the resonant circuit (1) which has low stray radiation so that frequencies of oscillations within the range of some tens of Gigahertz can be generated with fully balanced signal components. <IMAGE>

Title: Method for wet chemical etching of a semiconductor substrate
Inventor: KLIMARS STEFAN DIPL PHYS
IPC: G02B6/124
Filed: 1993-09-30
Abstract: A method for wet chemical etching of a semiconductor substrate, in which convex structures (4) are produced on the surface of a semiconductor wafer (1) by using a suitable mask and a suitable etchant, is intended to make it possible to obtain convex geometries, especially those suitable for microlenses, on semiconductor substrate material with high reproducibility. An etching mask, consisting of an upper and a lower masking layer, is applied onto the semiconductor wafer (1). The upper masking layer (3) consists of photoresist and is used as a structuring mask for the lower masking layer (2). Using the structured two-layer etching mask (2, 3), etching is carried out in an etching solution with double etching action, in such a way that etching erosion of the lower masking layer (2), proceeding inwards uniformly from all sides, defines an etching front independent of the etching mechanism at the semiconductor material, and the structures (4) in the semiconductor wafer (1) take on a convex shape which is faithful to the mask. <IMAGE>

Title: Mounting for vehicle-installed drive unit switched-off for free-wheeling in load-free drive phase - uses magnetic or piezoelectric active bearings in generation of realistic vibrations of bodywork while engine is stopped to simulate idling
Inventor: STAMM KLAUS DR
IPC: B60K6/10
Filed: 1993-11-24
Abstract: Active bearings are used which can be switched into a vibration-generating mode in accordance with switching criteria based on measurements of the rotational speed and load (i.e. throttle flap setting) of the IC engine. In engine-braking or idling conditions, voltages or currents with suitable waveforms are taken from memory and fed to a magnetic or piezoelectric system of the active bearings in order to simulate the vibrations transmitted from an idling engine to the bodywork. ADVANTAGE - The psychological difficulties associated with stalling of the IC engine during unloaded operational phases (e.g. waiting at traffic signals) are avoided by perpetuation of vibrations giving the impression of idling.
