Patent EP-0204521-A3 (EP)
Title: A heating and/or cooling system
IPC: F24F1/00
Filed: 1986-05-29
Abstract: A heating and/or cooling system having a system controller (10) and a number of heating and/or cooling sources (2-1, 2-2, 2-n), which may be multi-stage heat pumps, the heating and/or cooling sources (2-1, 2-2, 2-n) being operated in parallel with respect to the delivery of the heated or cooled working medium. Each of the sources (2-1, 2-2, 2-n) is controlled by an individual controller (5-1, 5-2, 5-n) which is issued with demand signals from the system controller (10). The system controller (10) commands the sources (2-1, 2-2, 2-n) to increase or decrease their heating or cooling capacity by comparing the temperature of mixed working medium from the parallel outlets (6) of the sources (2-1, 2-2, 2-n) to preset reference values. The system controller (10) sequentially energises or de-energises the sources (2-1, 2-2, 2-n) so that at any time the only minimum number of sources (2-1, 2-2, 2-n) which can satisfy the heating and/or cooling demand are energised.

Title: Hinge arm for a furniture hinge
IPC: E05D5/02
Filed: 1987-07-29
Abstract: The hinge arm can be linked to a baseplate either directly by means of a fixing screw or by means of an intermediate hooked plate screwed to the hinge arm and provided with a latching projection which can be moved against spring force. In order to be able to mount the hinge arm simply after changing over to assembly by means of a snap-in joint, the hooked plate (25) is provided with a guide for a slide (34) which can be moved against spring force and which has two hook-type extensions (44, 45) which are mounted on it approximately at right angles and spaced apart and which latch in behind holding edges of latch openings (60, 61), aligned with the latter, in the baseplate (20) in a snap-in action due to pressure exerted on the hinge arm (1) from above. Between the hook-type extensions (43, 44), the hooked plate (25) has a projection (31) or a recess and the baseplate (20) has a complimentary recess or a complimentary extension which perform a centring action by meshing in the latched state. At least one of the meshing parts is provided with a ramp-type inclined face (45) so that, after the hook plate has been placed on the latch openings, the slide (34) is pressed back against the force of the spring (38) when the parts are pressed together until the hooked edges (46) of the hook- type extensions (43, 44) drop in behind the holding edges in a snap-in action.

Patent EP-0264723-A3 (EP)
IPC: B29C45/28
Filed: 1987-10-08
Abstract: This invention relates to sealing and 
support bushings (92) which are located between the 
manifold (10) and the mold back plate (12) to encircle each 
valve pin (46) in a multi-cavity valve gated injection 
molding system. Each bushing (92) is bolted through the 
manifold (10) to a respective heated nozzle (14) with central 
bores (98, 44) in alignment to receive the valve pin (46) 
therethrough. The bushing (92) has an outer flanged 
portion (94) which extends to contact the mold back plate (12) 
and forms a leakage containment chamber (106) between 
them. Thus, the bushings (92) retain the manifold (10) in 
place, seal against substantial melt leakage around 
the reciprocating valve pins (46) and collect any melt 
which does escape to prevent it entering the 
insulative air space (86) between the hot manifold (10) and 
the cooled mold back plate (12). Location of the bushing (92) 
between the manifold (10) and the mold back plate (12) also 
enables the use of a standard manifold having 
longitudinal and transverse bores without requiring 
diagonal bores.
Patent EP-0274789-A3 (EP)
IPC: B29L31/60
Filed: 1987-12-10
Abstract: The invention relates to a method for manufacturing 
a layered construction, for example a laminate or sandwich 
panel, which construction comprises at least two parts adhered 
to each other with co-operating contact surfaces and containing 
thermoplastic material at least in the area of the contact 
surfaces, in accordance with which method the contact surfaces 
are pressed toward each other for a period of time while 
temperature is increased and the thus obtained construction 
is subsequently allowed to cool.  
     The invention has for its object to now perform the 
said method such that an excellent adhesion is obtained between 
the co-operating contact surfaces without this being accompanied 
by degradation of the core material due to high temperatures.  
     In order to achieve this aim the invention proposes a 
method of the type mentioned in the preamble which displays 
the feature that a quantity of solvent is applied to the 
contact surfaces of the parts such that some softening occurs 
locally and that an increase of temperature is caused to 
occur up to a temperature that is considerably lower than the 
softening temperature of the relevant thermoplastic material.

Abstract: A sonic transducer (16) is mounted in its individual 
sealed casing (10) so that it is protected against the entry of

of silicone gel. The sonic device in the form of the sonic trans­
ducer in its casing can be mounted as a unit in a bore in a 
stave (30) for carrying an array of sonic devices. Each device 
is protected in its individual casing against the entry of water 
so that a surrounding sealed casing for the assembly of trans­
ducers in the stave is not necessary.

Abstract: This invention provides for the most amount of concurrency 
of I/O and CPU processing by adding an intelligent hard­

the CPU and DMA controllers. This intelligent circuitry 
monitors CPU requests for main memory access and exter­
nally negates the I/O device's DREQ request signal. This 
in turn temporarily halts the I/O transfer, and allows 
the CPU to steal a bus cycle in the middle of an I/O 
transfer burst.

Title: Maschine zum Behandeln schüttfähiger, pastöser und/oder fliessfähiger Güter mit eingebauter Aufschliessvorrichtung
IPC: F16C3/02
Filed: 1989-07-25
Abstract: Bei bekannten Maschinen dieser Art ist es zum Auswechseln der 
Aufschließvorrichtungen erforderlich, diese mitsamt dem Antrieb abzubauen, 
wozu eine verhältnismäßig große öffnung in der Behälterwand erforderlich 
ist und viel Zeit und Arbeitsaufwand benötigt wird. Die neue Maschine soll 
es ermöglichen, die Aufschließvorrichtungen schneller und mit geringerem 
Arbeitsaufwand auswechseln zu können.  
     Bei der neuen Maschine sind die Aufschließvorrichtungen aus zwei 
voneinander trennbaren Teilen gebildet, so daß der die 
Zerkleinerungswerkzeuge tragende Teil der Aufschließvorrichtungen von der 
Innenseite des Behälters der Maschine eingebaut und auch ausgebaut werden 
kann, während der andere Teil dauerhaft an der Außenseite des Behälters 
befestigt wird.  
     Die Maschine benötigt für das Anbringen der Aufschließvorrichtungen 
nur verhältnismäßig kleine öffnungen in der Behälterwand, die, falls sie 
nicht benötigt werden, in einfacher Weise durch einen einsteckbaren Deckel 
verschlossen werden können. Ein- und Ausbau der Zerkleinerungswerkzeuge 
ist schnell und von einer einzigen Person zu bewerkstelligen, weil hierzu 
lediglich eine Schraube ein- bzw. ausgedreht werden muß.
