Patent DE-4136745-A1 (DE)
Inventor: ZETTNER HERBERT
IPC: F16C19/26
Filed: 1991-11-08
Abstract: Described is a cage for full-type radial roller bearings in which the rollers (4) are held securely for transport purposes in the roller pockets (2), which are delimited by ribs (3). Integral with the cage is at least one insert (6) rigidly connected to the bearing rings (1). The insert (6) extends round the circumference of the bearing in each direction for such a distance that the end clearance between the first and last of the rollers (4) touching each other is smaller than the clearance for a roller (4) in a roller pocket (2). This cage, which is mounted at a bearing point, ensures that the rollers (4) are separated under all conditions by the ribs (3). It is thus impossible for the ribs (3) to be damaged by the rollers (4).
Patent DE-4138800-A1 (DE)
Inventor: SCHUETTLER KARL-HANS
IPC: B65H67/02
Filed: 1991-11-26
Abstract: The invention concerns a process and a device for avoiding interruptions of operation caused by the strapping, on machines for the strapping of packing elements. The process is characterized by a second strapping coil with further strapping, and in that the leader of one of the two strappings is constantly kept at a standby position in the machine from which, upon removal of the other strapping from the strapping guideway, it is automatically fed to the strapping guideway. The device is characterized in that the feed system is preceded by a switch with two strapping guideways for a leader section for each one of the two strappings, with a strapping feed for the alternative introduction of one of the two strapping leaders into the feed system. A first drive system is provided within the vicinity of the strapping guideways for selectively introducing one of the strapping materials into the feed system, while a second drive system is provided within the vicinity of the supply coils of the strapping materials for selectively engaging one of the supply coils in order to retract or withdraw a damaged or depleted strapping material from the feed system and permit a second one of the strapping materials to be introduced into the feed system.

Patent DE-4219259-A1 (DE)
Inventor: HEHL KARL
IPC: B29C45/76
Filed: 1992-06-12
Abstract: In a method for controlling a plastics injection-moulding machine, the operating parameters required for the sequence of an injection cycle are input in a form guiding the operator via an input unit (E) into a data processing unit storing these operating parameters, and subsequently injection cycles are carried out in accordance with the stored operating parameters. During the input, with knowledge of the possible process sequence of injection cycles governed by physical and machine-and mould-related design conditions, and after entering the devices existing on the respective machine or assigned to it, a selective choice of input possibilities is made available to the operator for the sequence and the configuration of the injection cycle. As a result, the parameters necessary for setting up the injection-moulding machine can be input faster, at the same time reducing the frequency of errors. <IMAGE>
Patent DE-4219838-A1 (DE)
Inventor: GRUENHAGE HOLGER DIPL ING
IPC: E06B5/16
Filed: 1992-06-17
Abstract: Given a fireproof glazing, there is provided, at least on the side (9), of the pane (1), directed towards the fire and in the region of the rebate, a screening device (10) which can be activated and moved, in the event of a fire, independently of a pressing action on the pane. When a predetermined temperature is exceeded, the screening device (10) is shifted such that it entirely covers the edge region (24), of the pane (1), which is to be screened. The fact that screening and exertion of pressure on the pane are carried out separately offers the advantage that, when a predetermined temperature is exceeded, the screening device immediately fulfils its full protective action for the edge region and consequently keeps the pane edge cool for a relatively long period of time. The screening device (10) may have a slide (12) which is moved, in the event of a fire, by a pressure medium (11) which expands under the action of heat. <IMAGE>

Title: Water aeration system - has plastics tubes in a ring with cross tubes held by push fit joints and carrying outer elastomeric slitted bodies held in place by frames secured by nails
Inventor: JAEGER ARNOLD
IPC: B01F3/04
Filed: 1992-06-29
Abstract: The water aeration system, using rigid and pref. plastic horizontal tubes with passage openings to deliver air through flat and slitted outer elastomeric bodies, uses the tubes (1) in a ring structure partially linked by cross tubes. A push fit joint is at least between some of the tubes to join them together. Several tube sections are covered by bodies (11) with slits (12). The edges of the cladding bodies are held rigidly against the tube by a surrounding frame, and pressed home by inserting mountings such as nails or staples and the like, without prior drilling. The air distribution bodies and mountings are fitted to the tubes of the ring layout and also to the cross tubes. The covering bodies are only fitted to the peak of the tubes. The tubes forming the ring and the cross tubes are composed of straight sections, curved sections and T-pieces. The nails pass through the frame (13), the edge of the covering body and penetrate the tube wall. The slits in the covering bodies run longitudinally. USE/ADVANTAGE - The tube system, for water aeration, is easily assembled and dismantled.

Title: Telephone call signal processing arrangement - uses call tone recognition circuit which either accepts or rejects a clock signal depending on position in signal band.
Inventor: KINDERMANN DETLEF
IPC: H04M19/04
Filed: 1992-07-08
Abstract: The circuit arrangement for processing telephone - voice frequency call signals accepts AC signals within a permissible frequency range. AC signals outside this range are not regarded as voice frequency call signals. A call tone recognition circuit either accepts or rejects a clock signal depending on whether it lies within the calling tone - clock frequency band or not. For frequencies (fw) of the AC signals up to a threshold frequency (fwg), the clock frequency increases monotonically with the frequency of the ac signal, but for frequencies above the threshold, the clock frequency is restricted to a frequency zone (ftm, ftl) above the call tone-clock frequency band (bft). ADVANTAGE - Sufficient signal content provided for reliable evaluation and recognition of call signals.

Abstract: In the colorimetric analysis method, a statistically sufficient number of measurement value triples is obtained from measurement locations randomly distributed over the measurement surface.  Each coordinate in colour space is determined and used as a representative value for the colour components of the entire  multicoloured surface in which local accumulations of large numbers of measurement value triples occur randomly over the surface. Each colour measurement value triple, which has at least a defined number of further triples closely adjacent in colour space, are sorted into classes of such closely adjacent triples. These classes are used for further processing of the measurement values. USE - For process and quality control in textile, clothing and manufacturing industries.
