Patent DE-3815162-A1 (DE)
Title: Soft metal tube for viscous adhesives
IPC: G01F/
Filed: 1988-05-04
Abstract: Soft metal tubes for viscous consumer adhesives were for various reasons incapable of guaranteeing reliable dosing: firstly, they are not elastic enough that sufficient resiliency stopped the adhesive flow every time; secondly, even gravity-caused outflow is not adequately impeded; thirdly, they offer no resistance to heat-caused outflow and, fourthly, small air bubbles can penetrate which accumulate to form air bubbles, the relatively great thermal expansion of which expels the adhesive to a greater extent. An aid to counter reasons 1-4 above is the loose filling of steel wool which, however, creates problems in production because the slightly conical empty tubes are often delivered, in the case of an automatic filling machine, inserted inside one another in bars. An aid to counter reasons 1-3, but only to a limited extent reason 4, is small elastic plates inserted at the front into the tube. An aid to counter reason 4, and also adequately reason 2, is spout inserts which impede the admission of air; for many adhesives, remaining effects of reasons 1 and 3 can then already be tolerated, otherwise the combination of small plates and spout insert, even mounted as a unit, provides a remedy.

Title: Apparatus for aligning end papers
Inventor: THRANDORF HANS-PETER
IPC: B42C5/00
Filed: 1988-06-07
Abstract: The apparatus for aligning end papers is used in adhesive binding machines. For alignment, the end papers (1) of the book block, diverted by suction nozzles (10), are transferred to alignment rulers (15) on the guiderails (13). The determination of the end papers (1) is effected, according to the invention, by contact pressure rollers (17) positioned laterally on the guiderails and inclined in the transport direction, which press the end papers (1), with the assistance of spring force, onto the alignment rulers (15) and against the guiderails (13). The transport of the book block takes place during the alignment by means of an entraining chain (3) which transfers the material for processing to a block transporting device. Adjustment elements are provided for adapting the device to changing formats of the material to be processed. <IMAGE>

Title: Device for the measurement of infrared radiation
Inventor: HAAF WILFRIED DR RER NAT
IPC: G01J5/12
Filed: 1988-08-13
Abstract: A measuring device (1) has a measuring head (2) which consists essentially of a covering layer (4), a reflecting layer (5) located thereunder and an insulating layer (6) on the rear side. Arranged inside the measuring head (2) are temperature sensors (7, 7a, 7b) which are connected to a measuring and calculating electronic unit (3). Further measuring devices can also be connected to this measuring and calculating electronic unit (3). This results in a significantly simplified construction with simultaneously good measuring results. The thermodynamic processes in each part of the measuring device generate the measured signals as a whole so that, from the basic principle, no kind of auxiliary measures are necessary (Fig. 1). <IMAGE>
Patent DE-3831330-A1 (DE)
Inventor: RICHTER MANFRED
IPC: H04N9/79
Filed: 1988-09-15
Abstract: In a known method, an additional identical data packet is generated with each data packet, all data packets are subjected to a multi-level coding process and the information items associated with one line and present several times are recorded mutually offset in time on different helical tracks of a recording medium. During the playback of data packets recorded in this manner, the information in each case recorded on the other track, can be evaluated instead of the disturbed information in the case of a dropout. In this known method, coding is necessary on the recording side and decoding of the data packets is necessary on the replay side. The novel method is intended to manage without recording-side coding and without replay-side decoding of the data packets. In the novel method, each additional data packet is recorded in time-division multiplex with the data packets and the picture information of a preceding line. Recording and replay of wide band signals such as satellite television and/or HDTV signals.

Title: Toothed fastening for frames
Inventor: HERR MICHAEL
IPC: E06B1/60
Filed: 1988-11-03
Abstract: In terms of material and time used for mounting, the "toothed fastening for frames" is an extremely cost-effective method of mounting frames. A simple, serrated sheet-metal strip is less expensive and replaces a dowel. A headless nail is likewise less expensive than a screw and replaces the same. A number of hammer blows replace the screwing procedure.

Title: Method and circuit for extracting line-and frame-frequency synchronization pulses
Inventor: KIRSCHENSTEIN REINHARD
IPC: H04N5/10
Filed: 1988-11-19
Abstract: A method for extracting line-and frame-frequency synchronization pulses from a television synchronization signal is proposed. In this method, positive needle pulses (b) derived from the front edges of the television synchronization pulses (a) are first logically combined with pulses of a first pulse signal (d) for deriving the line-frequency synchronization pulses (H) in such a manner that, after one needle pulse (b) occurs, further needle pulses are suppressed for more than half a line period. Furthermore, the television synchronization pulses are sampled by means of the pulses of this first pulse signal (d) in such a manner that in the case of positive or negative pulse values of the television synchronization signal, a positive or negative voltage value is produced. After that, this voltage value influences a further sampling of the television synchronization signal by means of the pulses of a second pulse signal (e), in such a manner that in the case of positive or negative values of voltage value and pulse value of the television synchronization signal, a positive output signal value is produced and in the case of a positive voltage value and a negative pulse value of the television synchronization signal, a negative output signal value is produced, these output signal values representing the frame-frequency synchronization pulses (f). <IMAGE>

Inventor: MEINHERZ MANFRED
IPC: H01H33/24
Filed: 1989-02-07
Abstract: A metal-encapsulated, gas-blast power circuit breaker (1) has a gas-filled housing (2) and an interrupter unit (3) which is supported in an insulated manner in the housing (2). The switching path of the interrupter unit (3) is formed by two contact tubes (16 and 17) which are aligned axially and are arranged opposite one another, spaced apart. In order to control the electrical field in the region of the switching path, metallic fitting bodies (32, 33) which at the same time form control rings (36, 43) are fitted on the circumference of an insulating tube (31) which accommodates the contact tubes (16, 17). Large-area apertures in the fitting bodies ensure that an unimpeded gas interchange can take place on the surface and in the interior of the insulating tube (31). A power circuit breaker (1) of the present type is particularly suitable for use in metal-encapsulated, gas-insulated, high-voltage switching installations. <IMAGE>
