Patent EP-0284226-A3 (EP)
Title: Variable output oil pump
IPC: F04C2/10
Filed: 1988-03-03
Abstract: The invention provides a variable output pump of the gerotor type in which one rotor (16) meshes in two side by side annulii (14, 12) which can be aligned for maximum output and turned in opposite directions to be non-aligned for minimum output. The movement is effected by a gear train (20, 24, 29) displaced by a rack (40) which is hydraulically operated by pump pressure. Hence high pressure displaces the rack to result in lower output against lower pressure. A variation is described in which a control spool diverts fluid to either side of the piston according to need and this is displaced in one direction by the derived fluid pressure and in the other direction additionally by spring pressure transferred from the piston position by a lever system. This can give desired pump output/speed results at reduced power consumption.

Patent EP-0295843-A3 (EP)
IPC: F16B7/14
Filed: 1988-06-13
Abstract: An adjustable support member in which an inner 
tube (3) is slidably and telescopically mounted in an 
outer tube (1). Relative axial movement between the 
inner tube (3) and the outer tube (1) is prevented by a 
locking mechanism actuated by a movable end cap (6) 
connected by an actuator rod (9) to a cup (8) mounting 
balls (12) which protrude through holes therein. A 
cone (4) is fitted into the free end of the inner tube 
(3). A spring (7) acts against a collar (11) fitted to 
the actuator rod (9) to draw the cup (8) towards the 
cone (4) thereby forcing the balls (12) to jam against 
the inside surface of the outer tube (1) and axially 
fix the position of the inner tube (3) relative to the 
outer tube (1).

Title: Nxn single-mode optical waveguide coupler
IPC: G02F1/313
Filed: 1988-08-09
Abstract: The present invention relates to a NxN single-mode optical coupler (10, 
26) employing evanescent wave coupling between mutually adjacent optical 
waveguides (11) sufficiently close to one another to facilitate coupling among all 
the waveguides. An optical signal of a narrow frequency band, e.g. appreciably 
less than 100 gigahertz, introduced to an input port (15i) of one of the 
waveguides is found to be nonuniformly distributed among the output ports (16) 
of the coupler. A first embodiment uses the nonuniform distributions of 
narrowband optical signals to the output ports of the coupler to enable the 
present invention to be used as essentially a selective switching device. A 
second embodiment introduces one or more predetermined broadband optical 
signals to one or more input ports of the coupler to produce an appreciably 
uniform power distribution among the output ports of the coupler. A third 
embodiment uses electrooptic or magnetooptic waveguides and the application 
of a high-frequency, continuously changing magnitude, oscillatory electric or 
magnetic field (17), respectively, throughout the coupling region of the 
waveguides to produce a substantially uniform power distribution among the 
output ports of the coupler for a narrowband optical signal applied to an input 
port of the coupler.

Title: Image forming apparatus
IPC: H04N1/12
Filed: 1988-11-29
Abstract: An image forming apparatus has a plurality of image 
forming stations (1C,1M,1Y,1Bk) capable of forming different images which 
are to be correctly registered and superimposed. 
Elimination of possible image misregistration in each image 
station is executed on the basis of the result of detection 
of register marks (9C,9M, 9Y, 9Bk, 10C, 10M, 10Y, 10Bk) 
which are formed by each image forming 
station (1C, 1M, 1Y, 1Bk). The correction 
is executed at a timing which is 
independent from image forming sequences performed by each 
image forming station in accordance with image signals, 
e.g., during warming-up of the apparatus after the initial 
application of the power immediately after the input of 
image forming operation start instruction through a start 
key,or after completion of production of a predetermined 
number of copies counted from the last misregistration 
correcting operation.

Title: Adjustable flow and temperature stop mechanism for use in single control mixer cartridges in plumbing fixtures
IPC: F16K11/078
Filed: 1988-03-04
Abstract: An adjustable stop mechanism is described in which several 
longitudinal grooves are made in a mobile shaft (1) of the cartridge 
on which are fitted two sockets (2 and 3) which have in their 
interior the counterpart of these grooves, thus becoming integral 
with the shaft. One of these grooved sockets defines the rotation 
stop, limiting the maximum content of hot water in the mixture, 
while the other limits maximum flow, these being independently 
decided by the relative position with the grooved shaft.

Filed: 1989-02-02
Abstract: In a thread milling cutter comprising at its tip cutting edges for making a bore, said cutting edges are formed as face milling cutting edges which enclose a mutual angle of 180 DEG  or more, so that the thread milling cutter on reaching the intended drill hole depth and in order to be laterally moved need not first be raised. Also, it is possible with the thread milling cutter according to the invention when using said cutter to make threads of any desired diameter with the same thread pitch because the tool tip does not run against the drill hole bottom when laterally moved or offset as with the known thread milling cutter. In addition it is possible with the same tool to provide the thread at the entry with an edge-chamfer in such a manner that impairment thereof by formation of burrs is impossible.

Abstract: In a modulator for converting two digital signals of I 
channel and Q channel in base band into analog signals and for 
converting a component of the signals whose phase is the same 
as a carrier and another component of the signals whose phase 
is orthogonal to the carrier so as to produce an orthogonally 
modulated wave, the two digital signals are connected to one 
signal train by time-sharing and multiplexing them and the 
converted analog signals are separated to two analog signals

Title: Synchronized horizontal scanning at horizontal frequency multiples
IPC: H03L7/093
Filed: 1991-03-26
Abstract: A first phase locked loop (12) generates a first timing signal (on 17) at a first horizontal synchronizing frequency (1fH) corresponding to a horizontal synchronizing component (on 13) in a video signal (on 11). A converter circuit (56) derives from the first timing signal (on 17) a second timing signal (on 61), having a second frequency (2fH) at a multiple of the first frequency and subject to a variation in frequency at a rate corresponding to the first frequency. A second phase locked loop (62) receives the second timing signal (on 61), which can be asymmetric within the period of the first timing signal (on 17), and a feedback signal (on 73) in accordance with the second frequency, and includes a controllable oscillator (66) for generating a smooth horizontal synchronizing signal (on 67) at the second frequency. The second phase locked loop has a characteristic loop response, determined by a low pass filter (63), preventing the voltage controlled oscillator (66) from changing frequency as fast as the rate of variation of the second timing signal (on 61). This drives the error signal for the controllable oscillator (66) toward an average value, resulting in a corrected, symmetric synchronizing signal at the second frequency. A horizontal output deflection stage (68) may be coupled to the second phase locked loop (62) for synchronized horizontal scanning in accordance with the second frequency. No additional signal processing circuitry is needed to correct the symmetry of the first timing signal generated by the first phase locked loop or the symmetry of the second timing signal derived by the converter. <IMAGE>
