Patent EP-0181297-A3 (EP)
IPC: A61K6/847
Filed: 1985-10-23
Abstract: The present invention relates to a method of preventing 
the occurrence of corrosion of amalgam filling material for 
dental purposes, wherein a protective layer preventing 
continuous precipitation of metal from the amalgam filling 
and consisting of metal phosphates not easily dissolved in 
saliva, is caused to be formed along the exposed surfaces of 
the amalgam filling by initially incorporating phosphate ion 
donators in the amalgam filling material in the existing 
surroundings.  
     The invention also relates to a dental amalgam for 
preventing the occurrence of corrosion, for performing the 
method, wherein the dental amalgam contains phosphate 
ion donators in a quantity of up to 0,5% phosphor calculated 
on the weight of the amalgam filling material.

Title: Valve timing gear for an internal-combustion engine
IPC: F02F1/24
Filed: 1985-03-12
Abstract: In an internal combustion engine with a cylinder (1), the cylinder head (2) has four valves (3, 4) inclined towards each other and arranged to be radially aligned with respect to the combustion chamber, pairs of the valves being operable by a common camshaft (6) by means of conical cams (7). To make it possible to use such a valve control for high rotational speeds, too, bucket type tappets (8) are displaceably mounted between the radially aligned valves (3, 4) and the conical cams (7) in the cylinder head (2).

IPC: G01L13/06
Filed: 1987-06-04
Abstract: Methods and apparatus by which a transducer (20) is 
employed to create a digital signal representing 
numerically the value of a changeable physical 
parameter. The signal from the transducer is subject 
to large and unpredictable amounts of offset due to 
either or both (i) manufacturing tolerance departures 
from the desired target of creating a zero output 
signal value when the sensed parameter is zero and 
(ii) changes in offset due to changes in one or more 
physical conditions (other than the sensed parameter) 
to which the transducer and its associated electrical 
components are subjected. A bistate device (50) is 
associated with the transducer and controlled so as (a) 
to first apply artificially to the transducer a known, 
and preferably zero, value of the parameter --with the 
output signal value being stored so as to represent the 
then-existing offset, and then (b) to apply the 
changeable physical parameter to the transducer. The 
stored value of the transducer output signal is, in 
effect, subtracted from the output signal obtained in 
the second instance, to produce an accurate final 
signal numerically representing the existing actual 
value of the sensed parameter. A programmed 
microcomputer is preferably employed to carry out the 
necessary steps in the sequence, and apparatus of that 
character is described.
Patent EP-0262556-A3 (EP)
IPC: H03K3/356
Filed: 1987-09-22
Abstract: A flip-flop circuit (12) is disclosed which enables a 
single side pull-down operation for inputting test signals 
(90) during a test mode and alternately a dual side push-pull 
operation for inputting data signals (20) during the normal 
use of the circuit. A pair of inverter circuits (19,25) 
selectively feed complementary data signals to opposite 
sides of a bistable circuit (30,32) so that the circuit 
operates in the push-pull manner thereby decreasing the 
switching time of the flip-flop. A pair of transmission 
gates (22,28), which are coupled to outputs of the inverter 
circuits (17,27), electrically isolate any noise appearing 
of a data input from the bistable circuit. During a test 
mode of the flip-flop, a test signal is fed into one side of 
the bistable circuit and facilitates a single side pull-down 
operation of the flip-flop. Two such flip-flop circuits 
(12,14) are concatenated in a push-pull cascaded connection 
to provide a shift register latch (10).

Abstract: A modified construction for a non-linear or 
curved staircase employs a technique in which the treads 
(l7, 30) for the staircase are initially cut to the 
required shape and size. Flexible plywood boards (l5) of 
the same length and height as the required stringers are 
then attached to the treads with the treads positioned in 
the required locations and orientations so as to create a 
rigid self-supporting structure formed by the flexible 
boards (l5) and the attached treads (l7) and risers (l4) 
where required. The self-supporting structure is then 
finished by the attachment to the flexible boards of 
suitable laminations (l9, 20). Housed treads (l7) have 
the laminations applied to the outer surface of the 
boards. Exposed end treads (30) have the laminations 
applied to the inner side of the boards.

Abstract: U.S. Patent No. 4,487,368 describes a sprinkler having a 
wobbling water distributor head mounted at the end of an 
angularly disposed tubular water-transporting arm. The base 
of the distributor head is mounted loosely between spaced 
shoulders. The wobbling motion of the head causes the dis­
tributor arm to traverse a circular path, so that a circular area 
is sprinkled. The present invention provides a means for con­
trollaby varing the distance between the shoulders as the dis­
tributor arm rotates, whereby the dimensions of the area 
sprinkled are also controllably varied.

fibres (18) and solid constituents (10, 12) are pre-mixed 
(16), and deposited on a form (56) with the fibres (18) 
being randomly oriented. The pre-mixture is wetted by a 
fluid (72) which is capable of reacting with the cement 
(10), and the wetted pre-mixture is then subjected to 
vibration energy (82) whilst being held under pressure 
(100), to mix the fluid (72), fibres (18) and solid 
constituents (10, 12) and to facilitate the reaction of the 
fluid with the cement.

Title: Process for increasing the efficiency of a pre-polymerized catalyst
IPC: C08F4/659
Filed: 1987-09-21
Abstract: The invention provides a process for pre-polymerizing olefin polymerization catalysts and a process for increasing the efficiency of pre-polymerized olefin polymerization catalysts. In one process of this invention an olefin monomer is added to a fluid carrier stream containing an olefin polymerization catalyst. The carrier stream containing the monomer and the catalyst is passed through an elongated tubular reactor at a flow rate sufficient to provide a residence time in the tubular reactor of less than 1 minute and under temperature conditions to pre-polymerize the catalyst within the tubular reactor without plugging of the reactor. In another process of this invention a pre-polymerized catalyst is contacted with a cocatalyst or a mixture of cocatalyst and an electron donor prior to introducing the catalyst into a polymerization reaction zone. <IMAGE>

in each lithography step. Means and methods for many 
types of devices such as complementary lateral and 
vertical bipolar transistors, JFETs, Sits, MOSFETs,

Title: Grinding or polishing disc
IPC: B24D9/08
Filed: 1988-05-20
Abstract: A grinding or polishing disc consisting of a backing disc with attachable grinding or polishing fabric. The grinding or polishing disc can be clamped by means of a shaft piece in a drive chuck, in particular of a portable drill or power tool, in which arrangement strengthening of the shaft is to be further stabilised even at high speed with large grinding forces and in addition the use of the grinder with a smaller grinding surface is also to be made possible. This is done by the counter-screw above the backing disc being designed as an arched cover while leaving the margin of the backing disc clear, which cover, when the end flange bears on the underside against the backing disc, can be counter-screwed on the inside on the screw thread on the shaft end and thus bears on the outside against the backing disc by means of the cover margin in such a way that strengthening of the shaft is obtained when a nut is counter-screwed from the rigid shaft piece on the cover centre opening overlapping the flexible shaft piece.

Title: Removable pipette tip shaped as a container adapted to the shape of a receiving piece, especially a tapered pipette end
IPC: B01L3/02
Filed: 1989-06-22
Abstract: A fittable pipette tip consists of a vessel which is designed to fit a particularly conical fitting head of a pipette and which may be conical and has a fitting top opening and a bottom opening for receiving and discharging a pipette. A sealing portion with which the pipette tip is adapted to contact the fitting head is spaced from the top end of the pipette tip and is formed with a smooth inside seating surface and has a smaller wall thickness than other portions of the pipette tip so that the sealing portion of the pipette tip is yieldable for adaptation to the fitting head. The pipette tip is reduced in wall thickness at least in the sealing portion by a provision of recesses in the outside and inside surfaces of the wall of the pipette tip.
