Title: Beer froth measuring device - scanning beer and froth column for light absorptivity
Inventor: BARTELS WILLY DIPL ING
IPC: G01N33/14
Filed: 1980-06-19
Abstract: A beer froth measuring instrument includes a light source and a photoreceiver which are mounted on a platform and can be moved vertically along a transparent measuring cylinder in which beer has been poured to generate a head of froth. The light rays, pref. of a pulsed nature, are absorbed more by the fine creamy froth than by the loose large bubbles above it or the liq. beer below it, and a record is produced after the transmitted light rays have been converted to electric signals and amplified. A repetition of the measurements in time gives a record of the formation and duration of the creamy froth and gives an objective quality control.

Patent DE-3104002-A1 (DE)
Inventor: TROOST MARCEL ABRAHAM
IPC: H04Q11/04
Filed: 1981-02-05
Abstract: A line trunk group is connected by way of a compensating memory to an input and, in fact, to those of the time slot multiples of the PCM switching network. Uniform time slots of the pulse frame boundaries within the switching network are provided. However, in the last switching stage and, in fact, in time slot multiples, displacement of a pulse frame boundaries in the lines leading back to the trunk line groups is provided. In this manner, line trunk groups acquire the frame clock rate. This influences, in respect of time slots, the transmission of sub-items of information from the line trunk groups to the switching network with regard to pulse frames of these sub-items of information, i.e. the relevant time slot of the pulse frame boundaries. Cable transit time on lines from the switching network to the line terminal group and from the line terminal group to the switching network, and delaying influences within the line trunk group which result in partially constant and partially variable delay values, are compensated, in part, by the above-mentioned displacement and, in part, by storage in the compensating memory, which can be adapted in terms of storage time, and, in fact, by increasing the delay to a full pulse frame duration or in multiple thereof. Economy of storage capacity in the compensating memory is therefore provided.

Patent DE-3106698-A1 (DE)
Title: Installation for moving horses (horse guide track)
Inventor: RIXEN BRUNO
IPC: A01K15/02
Filed: 1981-02-23
Abstract: The invention relates to a ropeway with which horses are pulled in order to move them. The pulling lines are secured on the endlessly circulating rope. The problem with such a ropeway is the change in direction of the circulating rope on the deflection rollers. In this case, the connection point between pulling line and circulating rope migrates with a jerk into the new direction. The horse may not recognise this sudden change in direction, and in this way can become frightened and can cause damage. The invention eliminates this problem by virtue of the fact that the pulling line is not secured directly on the circulating rope at one point, but preferably in the centre of an intermediate member which is connected to the circulating rope at two articulated points lying one behind the other at a distance. The suspension point of the pulling line now no longer migrates about the deflection roller, but instead describes, considered in a plan view, a path of a gradual change of direction over a large curve. In this way too the horse is only gradually pulled into the new direction. In addition, an element having a large surface area is arranged as an orientation means on the pulling line in the field of vision of the horse, which element executes the gradual change in direction of the pulling line and thus makes this visible to the horse.

Title: Wall-free staircase which is assembled by bolts
Inventor: KERSKI PETER
IPC: E04F11/035
Filed: 1981-06-18
Abstract: The invention relates to a staircase which is assembled by bolts and can be installed in residential buildings, in particular so-called houses for single families. The object of the invention is to provide a staircase which is assembled by bolts, in particular a wall-free staircase which is assembled by bolts, and gives the outward impression of being a staircase consisting purely of wood, constructed without using any metal, but which, however, is distinguished by a high strength which can only be achieved by using strong metal bolts. In addition, the staircase provided by the invention is to be easy to assemble, that is to say without any special knowledge of the skilled worker. This object is achieved according to the invention in that in each case two edge-parallel threaded bushes (5', 5'') open to the underside (18) and upper side (17) of each stair (1), the top plate (9) of which bushes is concealed. The two threaded bushes (5'') which are open to the underside (18) have a thread which runs in the opposite direction from that of the two threaded bushes (5') which are opened to the upper side (17). In each case a threaded bolt (6), the two ends of which likewise bear oppositely directed threads, is screwed into mutually opposite threaded bushes (5', 5'') of two successive stairs (1), and the necessary depth of engagement of each threaded bolt (6) into a stair (1) is fixed by a lock nut (7) which presses against a countersunk washer (10) of the associated threaded bush, that part of the threaded bolt (6) located between the stairs (1) being covered by a wooden cladding (2). <IMAGE>

Title: Developer mixture and method for electrophotographic production of copies
Inventor: OKAMOTO YOSHIKAZU
IPC: G03G13/09
Filed: 1981-06-30
Abstract: A developer mixture which is used in an electrophotographic copier to develop a latent, electrostatic image recorded on a photoconductive surface contains toner particles which can be attracted magnetically by a small force, and granular carrier particles which can be attracted magnetically by a strong force and adhere triboelectrically to the toner particles. The toner particles and the granular carrier particles are essentially of the same size. During development, the toner particles are deposited on the latent image, resulting in a toner powder image. The toner powder image is subsequently transferred to an image-receiving material in the form of a sheet and fixed there, resulting in a permanent copy.
Patent DE-3127478-A1 (DE)
Title: Stereophonic device for broadcast or television reception or for recording and/or replaying audio or video recordings
Inventor: MOORTGAT-PICK WALDEMAR DIPL PH
IPC: H04N5/64
Filed: 1981-07-11
Abstract: According to conventional technology, the specified standards for the L and R stereo signals in stereophonic devices for broadcast or television reception or for recording and/or for replaying audio or video recordings requires corresponding decoding even when this is not required for technical or economic reasons in special cases. In those cases, there is as a result additional circuit complexity. The object of the invention consists in preventing such additional circuit complexity for actually unnecessary decoding of the transmitted sum and difference signals in accordance with the L and R output signals. This object is achieved for the devices initially mentioned by directly picking up and forwarding stereophonic signals of the type of the M = L + R sum signal and of the S = L - R difference signal by means of connecting sockets and connecting plugs (6, 9) at the M and S decoder (3). <IMAGE>

Title: Method and fuel injection system for forming and delivering a fuel-air mixture to the cylinders of an internal combustion engine
Inventor: BERTSCH RICHARD
IPC: F02M35/108
Filed: 1981-08-01
Abstract: The fuel injection system comprises an air intake pipe (1), in which an arbitrarily actuatable throttle valve (3) is arranged, downstream of which fuel can be injected into a mixing chamber (4), which is defined on the other side by a throttle element (5). Downstream of the throttle element (5) individual intake pipes (6) branch off from the air intake pipe (1) to the individual cylinders of the internal combustion engine. The throttle element (5) is actuated by a pressure load cell (30) as a function of the pressure differential on the throttle element (5) in such a way that it opens only as the intake air flow increases from approximately the upper partial load range onwards. When idling and in the lower partial load range the throttle element (5) remains closed and the mixture is transported by way of mixing ducts (14) branching off from the mixing chamber (4) to the individual cylinders of the internal combustion engine. A very good fuel preparation is thereby obtained in all operating ranges of the internal combustion engine which leads to a low fuel consumption and low proportions of toxic exhaust constituents. <IMAGE>

Title: Adhesive gun for laying skirting boards and carpet strips to be fastened thereon
Inventor: WAGNER HUBERT
IPC: B65D47/42
Filed: 1981-08-12
Abstract: Up until now, the skirting board to be attached has had to be coated with a contact adhesive by means of brushes, as has the carpet strip. Adhesive dropping from the brush often soiled the edge of the carpeted floor. The adhesive gun according to the invention now permits the skirting board and the carpet strip to be coated in an effortless and clean manner. The adhesive gun comprises a flexible plastic bottle for receiving the adhesive and a mouthpiece which is fastened thereon and has a transverse piece with nozzles for the discharge of the adhesive. Coating the skirting board and the carpet strip with adhesive is thus possible in a simple manner and without soiling the carpeted floor, which work then takes place.

Title: Device for testing the chassis geometry of motor vehicles
Inventor: RUEDIGER BERND
IPC: G01B7/315
Filed: 1981-09-11
Abstract: In a device for measuring the toe and/or the camber of a motor vehicle wheel, provision is made of a component which is suspended by universal joints and can be brought to bear centrally against the wheel rim or the wheel hub. Arranged in each case on the two elements of the suspension using universal joints is a resilient measuring tongue whose free end is situated between two pickups (measuring sensors). The two measuring tongues are at right angles to one another and to the wheel axis, so that one measuring tongue can be used to measure the toe angle and the other measuring tongue can be used to measure the camber angle. In the event of deviation from the desired value of the camber angle and of the toe angle, the associated pickup generates a signal which is rendered visible in a display unit and/or is used directly to set the camber angle or the toe angle automatically.
