Title: Improved process for preparing substituted phthalic anhydrides
IPC: C07C51/567
Filed: 1988-07-21
Abstract: Yield and assay (purity) improvements in the reaction of bromine and the Diels-Alder addition product of maleic anhydride and a conjugated diene in the presence of a nitrogenous acid acceptor are realized in the instant process. The heating time after completion of bromine addition is increased to more completely eliminate hydrogen bromide from the reaction medium and thereby drive the reaction to completion. Also, the type of catalyst selected for use is one which will yield a phthalimide by-product impurity having a boiling point which differs enough from the boiling point of the desired product to allow for distillative separation of the impurity and desired product.

Title: A silkscreen printer constructed for printing one and the same pattern in two mutually different and opposite directions
IPC: B41F15/40
Filed: 1988-03-29
Abstract: The present invention relates to a silkscreen printer (1) 
constructed for printing one and the same pattern by 
squeegee movement in two mutually opposite and mutually 
different directions. The silkscreen printer comprises a 
printing table (2) which is held stationary in relation to 
the printer chassis (3), a stencil (4) accommodated in a 
frame (5) above the printing table, and a squeegee arrange­
ment (6, 6′) which is arranged for reciprocal movement 
along the stencil, therewith to press ink through the sten­
cil (4) and onto print material (7) placed on the printing 
table, such as to transfer the pattern of the stencil (4) 
onto the material (7). One side of the stencil frame (5) 
is provided with a first pivot device (8) which is intended 
for pivotal co-action with a first pivot pin (9) when 
printing is effected by squeegee movement in a direction 
towards the first pin (9). The opposite side of the sten­
cil frame is provided with a second pivot device (10) which 
is intended to be brought into pivotal co-action with a 
second pivot pin (11) when printing is effected by squeegee 
movement in a direction towards the second pivot pin. The 
distance between the first and the second pivot devices 
(10) is somewhat greater than the distance between the 
first and the second pivot pins (11).  
     It is suggested that Figure 1 is published together with 
the abstract.

Patent EP-0342367-A3 (EP)
Title: Improved fuser for use in an electrophotographic print engine
IPC: G03G21/16
Filed: 1989-04-17
Abstract: A fuser (12) for use in an 
electrophotographic print engine having mutually 
compressible rollers (120-182) for uniformity and thoroughly fused 
toner images. Also, the need for paper fingers to guide 
image receptor sheets is eliminated. The wear on the fixing 
device in the improved fuser is reduced by preventing 
binding of oil leveling blades (332), removing offset toner, and the 
use of oiling rollers in conjunction with oil leveling blades (332) to 
apply oil to the fixing device. An improved fuser is also 
easily accessible and serviceable. The fusing device (12) is 
contained within a clam-shell housing such that the fixing 
device and the compression device are separated when the 
housing opens thereby freeing jammed image receptor sheets 
and allowing convenient access for further service and repair. 
In addition, an oil wick (323), an oil tank (286), and the leveling 
blade (332) comprise a subassembly which can be removed and 
replaced.

Title: System and device to control time intervals between billets in rolling mills
IPC: B21B37/00
Filed: 1989-05-10
Abstract: The present invention refers to a system and device to 
control time intervals between billets or blocks in rolling 
mills and/or similar equipment that allows such 
control.  
The system uses a signal which 
indicates the moment in which a billet has to be introduced in the 
first stand (1) of the rolling mill, observing a preset 
time interval and a real time interval indicator between billets. 
The device is a current comparator/analyser circuit. 
The invention allows an effective time interval control 
between billets minimizing this time interval, thus guaranteeing 
among other advantages, a significant increase in 
productivity.

Title: Shut-off valve
IPC: F16K5/04
Filed: 1989-05-19
Abstract: A plastic spring loaded shut-off valve for drains in live 
wells of boats seals without the presence of fluid pressure. 
This effect is achieved by a biasing 
spring (25) urging sealing flaps (20) 
against the valve ports (6A, 6B). The flaps are curved and have ribbed 
edges (121) to accomplish such sealing and prevent jamming of the 
ports. The biasing spring is secured to a rotating member (15) 
through slots (13) while the flaps are secured to the member by 
buttons (16). The spring and flap are also secured by a bar (123) across 
the flap, which has a bearing pad where it is contacted by the 
spring. The rotating member is rotatable on the underside of the 
valve top screwed to the valve body. Stops (40) on the inside of the 
valve top limit its rotation.

Title: Data transfer system including exchange
IPC: H04J3/22
Filed: 1992-09-28
Abstract: A data transfer system including an exchange, 
wherein the exchange transfers data by sharing a 
plurality of channels by a time division multiplex mode. 
In this case, the exchange transfers the data by variably 
allocating to the channels channel lengths to be occupied 
by the same. That is, it is possible to allot any line 
speed to any channel and therefore possible to mix 
signals with different data transfer speeds in the 
frames. This results in an exchange network with a high 
degree of freedom of transfer for the subscriber terminal 
equipment.
