Patent DE-2933320-A1 (DE)
Title: Engine efficiency testing using percentage indicating voltmeter - for showing revolution rate drop when one cylinder is deactivated
Inventor: BRECKEL WERNER
IPC: G01P3/48
Filed: 1979-08-17
Abstract: The test device for a multiple cylinder combustion engine has a revolution rate sensor rotating synchronously with the crankshaft. It drives a controllable, esp. a monostable multivibrator, switch with a constant closed or open period charging a capacitor to a voltage corresp. to revolution rate for input to a digital voltmeter. It enables a direct percentage display of the drop in revolution rate following the isolation of one cylinder. This provides a direct efficiency reading without computation. A second digital voltmeter (10) has a bias voltage applied to one input connection (D). The other input (C) is driven by an operational amplifier (11) driven in parallel with the first voltmeter (5) and with a variable potential divider (R5,R6,R7) connected to its negative input. The bias voltage corresponds to -100.00 on the display.

IPC: B01J49/05
Filed: 1980-02-13
Abstract: In exchanger resin, (A), regeneration by passing a regenerating agent concurrently over (A), the regenerating agent is pumped round in a closed cycle, contg. (A), until the reaction is completed. The process can be applied to all ion exchangers, esp. to cation exchangers for removing metal ions, e.g. from galvanising plant rinsing waters.

Regeneration pref. takes place in 2 steps. A regenerating agent- free, highly conc. extract is formed in the 1st step and a regenerating agent-contg. extract in 2nd step. About half of total regenerating agent required is used in each step. Extract of 2nd step can be used for pre-regeneration in a subsequent regenerating cycle. Regeneration is followed by a pref. multi- step washing process, in which the washing water too is pumped round in a closed cycle.

Title: Biaxially extended moulded bottle - with section from mouth to shoulder of resin having high mechanical strength and chemical resistance before stretching
Inventor: SUZUKI SADAO
IPC: B29C49/22
Filed: 1980-05-09
Abstract: Biaxially extended moulded bottle has a mouth and a neck lined with a mouthpiece (1) which is separately formed in a cylindrical shape. Mouthpiece is prepd. by the injection moulding of a resin having high viscosity (>1.0 IV value) such as satd. polyester resin, or polybutylene terephthalate resin, PVC resin, ABS copolymer resin etd. and having at the same time a height from the neck P1 including the mouth to the shoulder P2 close to the neck where the extention is applied to a lower extent; and a piece proper P prepd. from a low viscosity satd. polyester resin by the injection moulding by inserting (1) as a part of the mould is formed to obtain a bottle P' by a biaxially extending blow moulding by unifying said mouthpiece. Although biaxially extended moulded bottle using satd. polyester resin is widely used, the mechanical strength and the chemical resistance of such bottle are insufficient, since the part of the bottle from the mouth to the neck cannot be extended sufficiently during the injection blow moulding stage. Disadvantage is eliminated by using other resin having high mechanical strength and chemical resistance even when it is not extended biaxially for the material from the mouth to the shoulder.

Title: Tone call signal emitter - uses transducer and Helmholtz resonator to give varying frequencies at varied intervals
Inventor: BAIER KLAUS ING GRAD
IPC: H04R1/22
Filed: 1980-07-09
Abstract: The electro-acoustic transducer is constructed with a number of sound guides arranged behind one another, and is intended to produce a load signal via a Helmholtz resonator together with a sound horn which is coupled to the sound exit openings of the housing. The transducer element is controlled by a sound generator to give several audible frequencies one after the other at pre-determined intervals. To achieve this, the resonant frequency of the transducer is so chosen that it is tuned to the lowest frequency of the sound generator and the resonant frequency of the Helmholtz resonator to the highest. The loudness depends on the geometry of the transducer and the sound guides, whereas the frequencies produced depend on the tone quality of the transducer. Thus the signal can be made easily distinguishable from other signalling or alarm devices in the same vicinity by altering the pitch and patterns of the sound emitted.

Title: Assembly of closely spaced permanent magnets of alternate polarity - which are each mounted on own base with base slotted for final assembly
Inventor: MUELLER WERNER
IPC: H01F7/02
Filed: 1980-07-11
Abstract: To achieve easier magnetisation of the individual magnets (1,2) each polarity (N,S) is mounted on its own base plate (5,6). The spacing of the individual magnets is twice the finished spacing. One base plate (5) has slots (5a) of dimension slightly larger than a magnet block (2). After mounting and magnetising, the magnets on one base (6) are passed through the slots (5a) in the other plate to give the required alternate north-south assembly at close spacing. To compensate for the thickness of the slotted plate the magnets on the lower plate (6) can be made slightly thicker. Alternatively the lower plate can be provided with pads (6a) to make up the difference.
