Patent DE-1813227-B2 (DE)
Title: Sealing ring assembly in apparatus which is - to be heated during construction
IPC: F16K5/06
Filed: 1968-12-06
Abstract: Sealing ring, eg of PTFE which is located in a groove in one of the facing surfaces of two concentrically telescoped members, e.g. of valve in which the base of the groove is deeper at one end than the other. The sealing ring is a loose fit in the deeper end of the groove, in which it is located while the members are heated, e.g. to effect a welding operation. After cooling the ring is moved to the shallower end where it is a tight fit and establishes a seal between the two surfaces.
Patent DE-1950095-B2 (DE)
Title: Sync. system for TDMA satellite communication link - corrects sync. errors between satellite and ground stations by comparing received pulse frames with reference frequency
IPC: H04B7/155
Filed: 1969-10-03
Abstract: The synchronisation system, for a TDMA satellite communications link, has pulse frames from the satellite compared with a reference frequency at the receiving ground station and uses the resulting error to correct that ground station's transmit frequency. During a first control stage the IF frequency derived from the satellite's signal is held constant by comparing with a reference and the result used to regulated the frequency of the mixer's IF oscillator. During a second control stage the frequency error between the ground station's transmit frequency and the ground station acting as reference for the network is determined and used to control the sync. oscillator's in the ground station.
Patent DE-2035473-B2 (DE)
Title: Lateral locking mechanism for missile tracking periscope - uses self-centering bolt lever for precise alignment
IPC: G02B23/16
Filed: 1970-07-17
Abstract: The bolt is part of a T-shaped lever which is pivoted at one end on a stud fixed to a housing and jointed at the end carrying the bolt by a pin and slot arrangement to a driving lever. The other end of the driving lever is adjacent to the stud and is engaged by an actuator to move the levers into the locking position. A spring is fitted between the levers to hold them apart. A further spring anchored at one end to the pin and slot device acts against a spring-loaded locking member which holds the two levers in the locked position, and the locking member can be disengaged from the driving lever by means of a push-button mechanism.
Patent DE-2218810-B2 (DE)
Title: Superheterodyne radio receiver system - adds binary coded received signal to binary coded IF signal to avoid need for mixing
IPC: H03J5/02
Filed: 1972-04-19
Abstract: The superheterodyne receiver has digital circuits to initiate oscillation in the RF oscillator system. The received signal is binary coded and added to or subtracted from a binary coded signal representing the IF frequency. The oscillator frequency is obtained from this sum by decoding. In the case of subtraction the binary IF code is converted into its own binary coded decimal complement for adding to the coded received signal. The advantage lies in not needing the mix the signals and thereby avoids the disadvantages of such a process.
Patent IE-S64140-B2 (IE)
Title: Process for drying a material from solution
Inventor: FOLAN MICHAEL ANTHONY
IPC: F26B5/06
Filed: 1995-01-31
Abstract: A process for obtaining a solid or semi-solid material by drying a solution thereof which comprises expanding a spray of the solution, which has been supercooled, into a vacuum and collecting the frozen droplets of spray on a surface which is sufficiently cold to cause the frozen solvent to sublime from the frozen droplets at the vacuum pressure, thereby producing particles whose size can be controlled by choice of droplet size. Elevated temperatures or milling stages are not required, so the process can be carried out using an apparatus comprising a vacuum chamber (11) having refrigerated walls, a vacuum pump (17) and a condenser (18). The solution is sprayed into the chamber via a nozzle (16) and the frozen droplets are collected on the walls of the chamber (11) and sublimation takes place therefrom.
Patent IE-S80929-B2 (IE)
Title: Filter with form-retaining stabilizing means
Inventor: MCGOEY DONAL RICHARD
IPC: B01D46/10
Filed: 1997-11-26
Abstract: A filter comprises a filter medium (110) folded in a pleated manner into sheets (112). The sheets are kept apart from one another to form the optimum angle by a stabilizer (120) which is applied in a semi-liquid form, hardens into a desired shape and retains that shape after hardening independent of the final form of the filter medium.
Patent JP-2834170-B2 (JP)
IPC: H04L25/497
Filed: 1989-01-27
Granted: 1998-12-09
Abstract: In a system for transmitting a binary source signal from a data transmitter to a data receiver through a noisy dispersive channel, the data transmitter comprises a sliding block encoder which converts the binary source signal at a given symbol rate 1/T into an encoded binary data signal at a symbol rate P/TN, where P and N are positive integers such that N/P </= <2>log(3)/2 + 0.79248. Since the channel introduces intersymbol interference and noise into the encoded data signal, the data receiver comprises the cascade of a equalizer, a sampler and a reconstruction circuit which serves to reconstruct the binary source signal at the symbol rate 1/T. The improved reconstruction circuit consists of a detector in a cascade with a decoder with a decoder with memory, while the equalizer, sampler and detector are arranged for the detection of a ternary data signal at the symbol rate P/(2NT).
Patent JP-4116724-B2 (JP)
IPC: B41J3/407
Filed: 1999-02-01
Granted: 2008-07-09
Abstract: PROBLEM TO BE SOLVED: To provide a tag printer easy to handle. SOLUTION: A tag 12 is drawn out of a gate 28 by moving a suction pad 50 diagonally to the lower side by sucking and holding a head end lower side surface of the tag 12 stored in a storage part 16 in an accumulated state by the suction pad 50. Consequently, a clearance is forcibly formed between the tag 12 sucked and held by the suction pad 50 and the tag 12 on it. Accordingly, it is possible to certainly draw only the tag 12 sucked and held by the suction pad 50 from the gate 28, and height adjustment of the gate is not required with the tags 12 in any thickness. Consequently, handling of the printer is facilitated.

IPC: H04N5/08
Filed: 1980-04-03
Abstract: A composite video signal is coupled to the input of a tapped delay line of a vertical sync separator.

Patent JP-S6215603-B2 (JP)
IPC: C21C5/32
Filed: 1980-04-28
Abstract: A process for refining a metal bath in a converter by oxygen blowing, particularly a molten metal liquid bath containing cold, solid substances, notably of scrap. Oxygen is distributed over the surface of the bath, so that there will be an after-combustion of CO released in the course of decarbonization. The thickness and consistency of a slag layer formed over the bath is actively regulated by injecting a rising inert gas through the bottom of the bath. The flow of rising gas may be regulated depending upon the oxygen content in the fumes of the converter, or upon the intensity of emission through the top of an oxygen blowing lance.
