Patent DE-2951856-A1 (DE)
Inventor: ZWICKER EBERHARD PROF DR ING
IPC: A61B5/12
Filed: 1979-12-21
Abstract: In an exemplary embodiment, for testing the chronological resolution of hearing, acoustic signals are supplied to the ear to be tested via an earpiece and consist of a test tone which can be interrupted and of a masking sound which can be modulated, their frequency and amplitude level being adjustable. Complicated measures are necessary for the measurement of the so-called listening threshold period pattern in order to present a complete pattern for identifying the chronological resolution of the hearing. In contrast, the disclosure provides an uncomplicated measuring device which is also easy to operate and with which the maximum and the minimum of the listening threshold period pattern or, respectively, their difference can be determined. To this end, the disclosure provides a device with channels generating respective sound signals, each of the channels having its own generator. Whereas the first generator is designed in the manner standard given electro-acoustical audiometers, that for the second channel has a noise generator whose output is modified by means of frequency band selection filters to provide a noise band with a mean frequency which can be matched to changes in the selected frequency of the first channel, and whose output amplitude level can be increased to a suitable value in comparison to the quiescent hearing threshold level (RHS) of the test tone. The disclosed device is particularly suitable for use in testing hearing.

Title: Feed conveyor for mangle - has superimposed press conveyor mounted on rocker shaft forming elongated tapered input channel
Inventor: KREINBERG MANFRED
IPC: D06F67/04
Filed: 1980-06-02
Abstract: A device for feeding garments, etc., to a mangle or other finishing machine comprises a series of parallel, driven belts forming a feed conveyor, above which is a similarly- constructed press conveyor. After passing around the press roller, the press belts extend towards the input end of the feed conveyor, forming a wedge-shaped input channel of 20 deg. angle. The press conveyor is hung on a rocker shaft which lifts it away from the feed conveyor if a foreign body, or the hand of an operative, enters the input channel. This is a relatively inexpensive construction which has a high safety factor and which straightens out the leading edge of a garment, etc., before it enters the press roller nip.
Patent DE-3021083-A1 (DE)
Title: Loose material disintegration process by high pressure - involves pressurising with subsequent sudden pressure reducing to above-atmospheric
Inventor: PONZELAR HEINZ ING GRAD
IPC: C11B1/04
Filed: 1980-06-04
Abstract: The installation for disintegrating loose materials, such as fruits or seeds by high pressure consists of a vertical pressure cylinder subdivided by several closable partitions resulting in several separate pressure chambers. The material is brought in through a duct (1), and an admission valve (5) into a chamber (3). The chamber has a valve (6) at the bottom, which is closed during the filling operation. After completed filling operation valve (5) closes and the chamber (3) is subjected to a partial pressure, which is above atmospheric, but lower than the operating high pressure. The pressure is produced by operating a valve (21) fitted in a branch of supply piping (16) connected to compressor (10). When the partial pressure in chamber (3) is reached, the valve (6) at the bottom opens and the material drops into a further chamber (4).

Title: Sealing tip of specimen vessel - by pressure opt. with heat triggered by downward pushing of vessel while still attached to pipette
Inventor: GERKEN HERO DR ING
IPC: B01L3/14
Filed: 1980-08-06
Abstract: The lower, pointed end of an open-ended specimen vessel fitted to the bottom of a pipette is closed in order to retain the specimen by pushing down the specimen vessel, esp. using the pipette, axially until its pointed end comes into engagement or contact, whereupon the point is closed and sealed.

Title: Internally stiffened hollow plastics window frame - has internal stiffeners pushed into already constructed hollow outer frame
IPC: E06B3/22
Filed: 1980-10-29
Abstract: A closed frame, esp. for windows, is esp. of plastics and consists of a hollow section, inside which a further reinforcing frame is seated. The assembly is produced as follows. The outer, plastics, hollow closed frame (1) is first constructed, then openings (8, 10) are formed at its faces near the corners, then stiffening frame members (12) are pushed through these openings to seat in the voids of the frame, and then these stiffening members (12) are joined together at the corners to form a rigid stiffening frame. Finally, the openings (8,10) are closed. Pref., the stiffening or reinforcing components (12) are welded or sealed together at the corners to form the inner closed frame, or are bolted or screwed together. The openings may be sealed by plugs or caps welded or sealed in position. The method of construction is extremely simple, and eliminates complicated procedures for sealing or welding at mitred and similar joints.

Title: Full adder switchable to subtraction
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1981-01-27
Abstract: The switchable full adder-subtracter according to the subject matter of the invention has two control lines s and i which are interconnected via a negating circuit. Those AND circuits which are needed for addition only have an additional input which is connected to the addition control line s. Those AND circuits which are needed for subtraction only accordingly have an additional input which is connected to the subtraction control line i. In this way, this computing unit can be switched from addition to subtraction and vice versa. The number 6 (LHHL) is added automatically before the addition in each decade and subtracted once more before the display of the result number (sum). The subtraction is carried out without this cardinal number since no cardinal number is required here. This computing unit is shown in Figure 3. <IMAGE>

IPC: F16D55/00
Filed: 1981-03-05
Abstract: In a spot-type floating calliper disc brake, a floating calliper (25) of first-like design surrounds the brake disc. The brake shoes (26) are held independently of the brake calliper (25) in brake-shoe support and guide webs (11). Provided on the brake anchor plate (18) are arms (19) which, at a point nearer to the brake cylinder (12) and radially further in than the brake-shoe support and guide webs (11), have axial guideways (16) with a V or semi-cylindrical cross-section. In order to be able to dispense with an expensive pin guiding means and to guarantee simple and reliable assembly, the essentially axially extending rectilinear limbs (14) of a leaf spring (15) of essentially U-shaped design engage in the guideways (16). The limbs (14) are prestressed in opposite directions in the circumferential direction. <IMAGE>
