Title: TV receiver with video-text module - has PLL producing sync. signals with output derived from frequency divider when no TV signal is received
Inventor: WIESSNER GERHARD
IPC: H04N5/06
Filed: 1989-07-22
Abstract: A pulse separator (9) takes signals from the receiver (1) and separates out videotext signals, as well as line and image sync. signals. An oscillator (10) clock synchronises a data processor (7) and a character generator (8). A frequency divider (11) divides the clock, which is at an integral multiple of the line rate, and produces line rate outputs to a phase comparator (12) in a control loop.  The drive and image sync. signals, for text mode without simultaneous  from a t.v. transmitter, are derived from the output signals of the divider. ADVANTAGE - No t.v. reception needed, allowing display of any desired text. @(4pp Dwg.No.1/1)

Abstract: An injection molding system having a number of heated nozzles (10) or probes, each with a forward nose portion (28) extending in a well (17) in an insert (18) in alignment with a gate (34) leading to a cavity. A circular cooling fluid passage (142) extends through the insert (18) around the nose portion (28) adjacent the cavity.

Patent DE-4009465-A1 (DE)
Inventor: BAUER ADOLF ING GRAD
IPC: B29B7/76
Filed: 1990-03-23
Abstract: In a device for mixing at least two reactive plastic components, the plastic components are injected under high pressure into a cylindrical mixing chamber (1) and at the same time intensively mixed. A mixing chamber plunger (3) is reversibly guided in the mixing chamber. The mixture of the plastic components flows out of the cylindrical mixing chamber into a settling chamber (4), which is arranged at an angle to the said mixing chamber and in which a settling chamber plunger (5) is reversibly guided. To avoid a situation in which, to control the pressure in the mixing chamber, the settling chamber plunger has to be arrested in a position in which, while keeping a flow-restrictor gap clear, it partially covers over the outlet opening of the mixing chamber, arranged at an angle after the settling chamber is a second settling chamber (6), in which a second reversible plunger (7) is arranged. <IMAGE>

Title: Initialising procedure for single Bus multiprocessor system - uses arbitrator unit to allocate user identification numbers and to determine mutually acceptable data handling parameters
Inventor: KOCK JUERGEN
IPC: G06F13/366
Filed: 1990-03-26
Abstract: The initialising process is started by the arbitrator unit (ARBIT) transmitting an interrogation signal (INIT) over the common BOs (SPBUS) to all users (TN1.TNx). Each user sub-system (SL1.SLn) responds by sending a unique control unit (CU1.CUn) derived synchronising signal (INITGRA1) back to the arbitrator unit (ARBIT) to indicate an on line condition. The arbitrator unit (ARBIT) then allocates user and sub-system numbers to complete phase 1 of the initialisation. In phase 2, system parameters, dependent on user sub-system characteristic and performance capabilities, e.g., (clock frequency - data width) etc., are determined by the sequential transmission of parameter values between the arbitrator unit (ARBIT) and sub-systems (SL1.SLn) until mutually acceptable values are achieved. USE/ADVANTAGE - The arbitrator unit organises data exchange and main frame access to a number of users whose require different working parameters due to varying equipment performance. Cost effective method of extending the useful life of user equipment.

Title: Disperser bowl with propeller above base pump - and outer slotted stator ring minimises rotary potion and air entrainment
IPC: B01F15/00
Filed: 1990-06-27
Abstract: Centrally in the base of a dispersion bowl is a pump unit for horizontally discharging in a radial direction, drawn down from the upper area of the bowl.

Filed: 1990-10-04
Abstract: In order, in a construction, especially a dwelling or holiday house, to be able to cast the walls and the intermediate floor situated above in one step from concrete without having to attach a separate ceiling form after erection of the walls, it is proposed to use for each room of the construction a room form consisting of a plurality of assembled form elements (4) which bound the room and of an inflatable balloon envelope (5) which is arranged in this room. After inflating the balloon envelope, the latter completely fills the room surrounded by the form elements (4) and covers it in the manner of a dome. If a formwork erected in this way is filled with concrete, the wall surfaces of the rooms are defined by the form elements (4), whereas the ceiling surface is formed by the dome-like balloon envelope. The external form elements (1) are for this purpose at least as high as the storey height plus the thickness of the intermediate floor. <IMAGE>
