Patent DE-3131677-A1 (DE)
Title: Adhesive bond to wall parts
Inventor: HAGEN PETER
IPC: E06B3/56
Filed: 1981-08-11
Abstract: The aim is to make an adhesive bond to wall parts, in particular insulating glass panes, more rapidly handleable (reduction of the handling time) by considerably reducing the volume of adhesive introduced into the adhesive bond whilst ensuring a final bond strength which is at least just as good as when a large volume of adhesive is used. This is achieved by inserting a profile strip, as frictional-locking bridge, between those regions of the wall parts to be adhesively bonded and by forming thin adhesive layers between the profile strip and those surface regions of the wall parts lying opposite it. Preferably, the material of the profile strip and the adhesive should be matched to one another such that, on hardening, the adhesive enters into a surface bond with the material of the profile strip by vulcanisation bonding, polymerisation bonding or condensation bonding. Profile strips comprising a material of the same or related chemical basis as the adhesive are preferably used. A preferred material pair comprises uncured silicone rubber as adhesive and silicone rubber of essentially the same chemical basis as the uncured silicone rubber as the material of the profile strip. The stiffness of the profile strip material should preferably be adjusted to a value which is also finally established in the adhesive where it cures.
Patent DE-3139883-A1 (DE)
Title: Stackable container which can be closed by a lid
IPC: B65D43/02
Filed: 1981-10-07
Abstract: The invention relates to a stackable container which can be closed by a lid. The lid has a lid trough which projects on its underside, the shape of which is adapted to the cross-section of the upper edge of the container body, and which engages in the container body when the lid is placed on. The bottom of the container body is dimensioned such that it fits in the lid trough of a lower container which is closed by a lid, and that secure stacking of the containers one on top of the other is possible. However, it has previously not been possible for individual lids to be placed on one another in an anti-slip manner since elevations projecting laterally outwards from the trough side wall can only serve as a resting surface and there is no safeguard against lateral displacement. To achieve nestability, the lids according to the invention are constructed in such a way that the underside of the trough bottom has at least at two opposite points on the trough edge in each case a downwardly protruding projection which comes to rest on the inside of the trough side wall of the next lid down when the lids are nested. As a result, a safeguard against lateral displacement of the lids is provided so that nesting is now possible.

Title: Electric fuse arrangement for a hammer-blow valve
Inventor: PETER JUERGEN DIPL ING
IPC: F16P3/00
Filed: 1981-10-09
Abstract: There is an electric fuse arrangement for a hammer-blow valve (1), in which there are located in an electrical control circuit (3) the control contact (6) of a foot switch (7), an electrical actuating device (2) of the hammer-blow valve, and a voltage source (4, 5). It is desired in this case for undesired trippings of the forging hammer to be practically avoided with the aid of simple means. This is achieved by using an additional fuse probe (12) so that a double timer (26A + 26B) is set going, which during a set time interval keeps closed a fuse contact (29), which opens after expiry of the time interval, of a first monitoring relay (17) and keeps closed a fuse contact (30) of a third monitoring relay (18) in the control circuit (3), and that the contact (11) of the fuse probe (12) is located in the input circuit (25) of the timers (26A + 26B) in series with the break contact (8) of the foot switch (7), the break contact (13) of the first monitoring relay (17), the break contact (14) of the monitoring relay (18), and the break contact (16) of a second monitoring relay (20), which is actuated in the event of an offset voltage in the control circuit (3). What is essential are the control functions and their combination with the time scanning "operationally ready". <IMAGE>

Title: Polarisation microscope
Inventor: BERGNER JOACHIM
IPC: G02B21/00
Filed: 1981-10-29
Abstract: The invention relates to a polarisation microscope for rapid determination of optical path differences. The aim of the invention is to guarantee observation in the case of a polarisation microscope with inclined binocular viewing in an ergonomically favourable position, and substantially to reduce the outlay on optics and material. The object of providing a polarisation microscope with inclined binocular viewing and with the simultaneous possibility of observing an object and a polarisation-optical element superimposed in the image plane thereof without deflection of the beam between the object and polarisation-optical element even in the case of the use of a conventional tube analyser is realised by means of an subsidiary optical system, which can be inserted in the telecentric beam path between the lens and analyser upstream of the first beam deflection and is constructed as an afocal system of two elements having a common focal plane and equal focal lengths. The polarisation-optical element can be brought into this focal plane, and the front focal point of the subsidiary optical system and rear focal point of the lens as well as the rear focal point of the subsidiary optical system and a principal plane of a tubular lens employed coincide.

Title: Process for producing a continuous pressure belt for apparatus for the continuous pressing and decatising of fabrics, knitted fabrics and the like
Inventor: RIEDEL DIETER ING GRAD
IPC: B29D29/00
Filed: 1981-12-14
Abstract: In this process, one or more than one unvulcanised rubber layers are empressed onto at least one side of a continuous fabric consisting of aromatic polyamide fibres at room temperature and the article produced in this manner is vulcanised for several hours under the customary longitudinal tension by placing it against a heated, specular surface. The object of the invention is to devise a process of this type which makes it possible to maximise the life of such belts by avoiding notch effects. This object is achieved by surrounding the polyamide fibres, before processing to give the fabric, with a rubber-compatible layer. Expediently, the intended rubber-compatible layer comprises at least one polyester thread which is wrapped around each polyamide fibre. Advantageously, the polyamide fibres used are aramid fibres. However, it is also possible to use Kevlar fibres as the polyamide fibres.

Title: Additional clutch actuation device for a one-way clutch in a motor vehicle
IPC: F16D48/04
Filed: 1982-02-25
Abstract: A clutch actuation device in a motor vehicle is to be capable of being controlled by a clutch pedal and additionally and independently by a one-way clutch. At the same time it is proposed to provide, in addition to a clutch pedal (12), a hydraulic auxiliary piston (2) connected to a two-way valve (15), controllable by the one-way clutch, which piston acts on the means, such as a fluid column or a Bowden cable or the like, actuating a clutch lever (23). The clutch can thereby be opened by the hydraulic auxiliary piston (2) independently of the clutch pedal (12). In order to trigger the hydraulic auxiliary piston (2) the two-way valve (15) is actuated by means of two electromagnets (18 and 19), a displacement (7) of the auxiliary piston (2) being connected either to a pressure line (17) of a pressure source or to a discharge line (16). <IMAGE>

Title: Arrangement for the automatic adjustment of the ground clearance of the body of a vehicle
Inventor: HEIL HERBERT ING GRAD
IPC: B60G17/015
Filed: 1982-06-22
Abstract: The angle of attack of the body of a vehicle, in particular that of a passenger vehicle to the roadway or to the direction of flow of the air is adjusted in such a way that a minimum drag coefficient is obtained. This is intended to avoid unfavourable influences on the angle of attack of the body and hence on the aerodynamic characteristics when driving and upon loading the vehicle. For this purpose, the invention provides an arrangement for the automatic adjustment of the ground clearance of the vehicle as a function of the driving speed, by means of which vertical adjustment is carried out independently at the front axle and the rear axle. Compressed air cylinders are used for the vertical adjustment, being fed by a compressor. The electronics of the vehicle are designed in such a way that the tachometer can send pulses to the level sensors assigned to the front and rear axle, which control solenoid valves for raising and lowering the body at a predetermined driving speed.

Title: Method and arrangement for measuring frequencies
Inventor: OHARA MASAKI DIPL ING
IPC: G01P3/489
Filed: 1982-09-17
Abstract: For measuring the frequency of input pulses, reference pulses (A) having a constant, relatively high frequency (f0) and timing pulses (B) of constant period (T) are generated. The number (Qn) of input pulses (E) occurring between two successive timing pulses (B) during a time interval, and the number (Pn) of the reference pulses generated during one time interval which begins with an input pulse (E) and ends with the timing pulse (B) immediately following it, are measured. After that, the following arithmetic operation is carried out: <IMAGE> where k is a constant, PT is the number of reference pulses (A) generated during one period (T), Qn is the number of input pulses in each case counted and Pn or Pn-1 is the respective or the respectively preceding counted number of reference pulses. The result of the arithmetic operation is output as a digital value. The invention is used for measuring variable frequencies. <IMAGE>

Title: Driving and/or deflecting drum for conveyor belts
Inventor: ALLES RAINER DIPL ING DR
IPC: B65G39/07
Filed: 1982-09-18
Abstract: The driving and deflecting drums in belt conveyor systems are usually provided with an elastomeric surface covering, and, for reasons of better water removal and more effective power transmission, arrow-shaped or crossing channels or other profilings are formed in or subsequently cut into the covering. According to the invention, the profiling is such that its depth or surface pattern changes from the drum centre to the edges, the arrangement preferably being such that the surface elements which support the conveyor-belt section lying on them are given greater mobility in the edge regions of the drums. As a result, the longitudinal stresses occurring at different levels over the belt width can be better evened out, the consequence being that unavoidable wear is on the whole reduced and, at any rate, more uniformly distributed.
