Title: Light fitting with a transparent housing
IPC: F21V7/22
Filed: 1989-03-25
Abstract: Despite the use of a reflector (5) for directing the light, it is the aim in an outdoor-lighting fitting having a transparent lighting fitting housing (1) to obtain the visual outward appearance when the light source (3) is switched on in a manner adapted to the outward appearance in daytime, and to obtain in the event of a sufficiently high proportion of light directed onto a working surface as uniform as possible a distribution of brightness on the surface of the lighting fitting housing (1). This is achieved by using for the body of the reflector (5) a cloudy, translucent carrier material which is evaporated on with a partially transmitting reflective layer in the visual wavelength region. It is thus possible, in particular, for light fittings in pedestrian zones to be attractively styled and at the same time optimised in terms of lighting technology. <IMAGE>

Abstract: This shredder-mixer-distributor trailer (1) comprises 
an elongated box-like container (2) longitudinally 
accommodating lower (3, 4) and upper (5, 6) rotating 
scrolls. The lower scrolls are arranged mutually close and 
convey material toward the front portion of the container,

scrolls (3, 4) define spirals with constant height and have 
two vertical baffles (10, 11) interposed therebetween. The 
upper scrolls (5, 6) define a variable-height spiral with 
portions extending along opposite directions. The container 
longitudinally accommodates wedge-like elements (21, 22, 25) 
for adjusting the feed to the lower scrolls and avoiding 
accumulation of material toward the walls of the container, 
and toothed-blade elements (27 30) for improving shredding 
and keeping the scrolls clean. A loading bucket (31) is 
integrated in the rear portion of the container while front 
doors (33) allow unloading of the shredded material.

IPC: B29C51/16
Filed: 1989-08-07
Abstract: The invention relates to a further development of the method for the manufacture of shaped parts or objects from thermoformable plastics films, webs or sheets by deep drawing according to Patent Application P 37 14 366.2. In this method, the plastics films, webs or sheets are deep-drawn and formed and/or embossed or decorated over their entire length, the forming and/or preforming being carried out with the assistance of a pressure difference and with the avoidance of a reduced pressure acting on all sides and use being made, instead of and/or together with a shaped male mould, of a shaped support which has on its surface facing the deep-drawing mould the shape, shape regions or surface regions of the deep-drawing mould (in positive form) and is moved against the deep-drawing mould. The film is deflected or preformed by the pressure difference and/or by the support in the direction of the deep-drawing mould and, during or after the thermoforming, the support is bonded to the plastics film, web or sheet formed in the deep-drawing process and located in the deep-drawing mould.

Title: Method of examining an inside surface-coated metallic pipe and apparatus for use in such method
IPC: G01N27/20
Filed: 1989-11-21
Abstract: A process for detecting a poorly coated portion of an 
inside surface of a pipe (5) coated with insulation coat 
(7) comprises the steps of providing a plurality of pigs 
(2) on a conductor (1) at predetermined intervals, 
preparing a running element (4) provided with many 
electrode needles (3) radially between these pigs (2), 
inserting the running element (4) into the pipe (5) while 
measuring the insulation resistance between the pipe (5) 
and the conductor (1), and moving the running element (4) 
inside the pipe (5) by adjusting the pressure inside the 
pipe (5).  
     From the above process, when the electrode needles 
(3) make contact with a poorly coated portion of the 
inside surface while the running element (4) is moving 
inside the pipe (5), the insulation resistance between the 
pipe (5) and the conductor (1) is decreased, thereby 
enabling the presence or a poorly coated portion and its 
position to be easily detected.

Patent EP-0350191-A3 (EP)
Title: Push pull resonant flyback switchmode power supply converter
IPC: H02M3/337
Filed: 1989-06-26
Abstract: A flyback converter high voltage power supply which 
includes two switches (Q10, Q11) operating in push pull fashion 
to provide alternate polarity energy pulses to a load (30). A 
main component of the power supply is a transformer (T10), the 
primary winding of which is divided into halves (P1, P2). The 
secondary may also be split into halves (S1, S2), or may be 
configured without a split so long as the secondary and 
rectifier combination result in full wave rectification. The 
first of the two switches (Q10) couples an input voltage (Vin) 
across the first primary half (P1) to store energy in the 
magnetic core during a first time interval, and at the end of 
the first time interval disconnects the first primary half (P1) 
from the input voltage (Vin). During a second time interval, 
the energy stored in the magnetic core during the first time 
interval is delivered to the load (30) via the secondary winding 
(S1, S2). The second of the two switches (Q11) similarly 
couples the input voltage (Vin) across the second primary half 
(P2) to store energy in the magnetic core during a third time 
interval, and then disconnects the second primary half (P2) from 
the input voltage (Vin) at the beginning of the fourth time 
interval. During the fourth time intevral, the energy stored 
in the magnetic core is again transferred to the load (30) via 
the secondary. A duty factor modulator is used to control the 
switching of the first and second switches (Q10, Q11) to vary 
the length of the time intervals in reponse to variations in the 
load and input voltage.

energy are transmitted. A single receiver responsive to 
the repeating sequence of internal RF pulses receives 
radar return signals based on all of the RF frequencies in 
a receive repeating sequence of receive intervals which do 
not occur at the same time as said transmit intervals.

Patent EP-0366588-A3 (EP)
Title: Memory organization with arrays having an alternate data port facility
IPC: G11C8/12
Filed: 1989-10-10
Abstract: A memory organization having one or more groups of memory 
arrays is disclosed. Each array, which may be on a single 
chip, is provided with both a data port and a separate 
address port which may also serve as an alternate data 
port. Use of the alternate data ports permits a substan­
tially smaller number of input/output circuits to be used 
than the number required if both the address and data 
ports are used. The standard data port is, however, avail­
able should a higher-speed application be desired using 
separate address and data ports. In a single-port applica­
tion, an on-chip data buffer permits the data to be sent 
and received through the address port in timed relation­
ship with row and column address signals and without 
interfering with such address signals. An optional group 
select signal permits a large memory organization to 
utilize the alternate data ports of numerous groups of 
array chips.

Title: Improvements in and/or relating to a process for preparing a hydrolysed lignocellulosic material
IPC: C08H8/00
Filed: 1990-05-08
Abstract: An energy efficient process for hydrolysing lignocellulosic 
materials which comprises using a primary system by providing a start-up 
energy input to operating saturated steam conditions and thereafter 
operating the primary system with substantially constant energy input, 
the condition of the hydrolysing saturated steam being controlled by 
water injection and/or steam bleeding from the primary system. The 
dwell time of the solids stream in the primary sustem is controlled by 
controlling its passage with flashing off of steam into a secondary 
system where drying occurs together with some small measure of 
hydrolysis in a lower pressure superheated steam environment, there 
being an energy input into the secondary system using steam bled from 
the primary system.  
     The output solids material stream is preferably capable of being 
self polymerised into a formed shape  eg  a board.
