Abstract: To close the gaps (6) which result between the end or edge sections (7) of the gravure printing plates (2) when the latter are clamped on form cylinders (1) of rotary gravure presses, the gap (6) is covered with a cover element (8) in which at least that surface region which lies on the end or edge sections (7) of the gravure printing plate (2) and covers the gap (6) is deformable under pressure and can therefore be matched up with the surface contour in the gap region, the cover element is pressed onto the surface of the gravure printing plate, the resulting gap cavity is filled with a curable filling compound and, when curing of the filling compound is complete, the cover element is removed. It is particularly advantageous to use cover elements which are in the form of hollow bodies and which are filled with a pressure-generating and pressure-transmitting medium, and the pressure exerted on the deformable surface of the cover element which lies on the gravure printing plate, and hence also the surface contour of the closed gap, can be controlled via the internal pressure in the cavity of the cover element.

Abstract: A method and a circuit arrangement for clock synchronization in the transmission of digital information signals. In the four-wire type transmission of blocks of information signals on a two-wire transmission line it is determined, by phase comparison, whether the first bit in each block of signals (1) falls within a time interval derived from the bit clock signal of the local clock generator; (2) falls within an adjacent time interval or (3) falls within none of such time intervals. Depending upon the results of this comparison, the time relationships are left unchanged, the period of the clock generator is shortened or lengthened one or more times, or a one-time, initial phase equality is established.

Abstract: A bag (1) for use in the shaping of liquid food products or stimulants consists of two plastics foils (2, 3), which are welded together in such an area of the two foils as will provide a plurality of interconnected mould cavities (4) with a common inlet (5). In the mould cavities (4) there are placed sticks (6) which are held in position by the positioning in a channel (8) having a length and cross-section corresponding to the holding part (7) of the stick (6). When the bag is filled with liquid ice cream or a similar material, the mould cavities (4) are distended three-dimensionally, and when the length of the sticks (6) is suitably dimensioned with respect to the length of the mould cavities (4), the sticks will be firmly "fixed" within the mould cavities (4). The sticks (6) are therefore placed in the middle of the ice lollies formed after freezing.

Abstract: The invention relates to a method for improving the hearing of a hearing-impaired subject. If the subject is anatomically normal he has a tympanic membrane intended for generating mechanical tympanic vibration in response to sound waves impinging thereon. Said method comprises the steps of: interrupting the ossicular chain to preclude transmission of mechanical vibrations between the tympanic membrane and inner ear of a subject; and, surgically interposing an implant comprising input and output transducer means for mediating mechanical/ electrical signals, having controlled amplification characateristics, within the interrupted ossicular chain to bridge the interruption therein and form an independent link between said tympanic membrane and said inner ear.

Patent NL-97379-C (NL)
IPC: C07C201/02
Abstract: Nitric acid esters of aliphatic alcohols are manufactured by introducing the nitrating acid into an injector under pressure, the alcohol and a non-reactive gas, in an amount from 5 to 30% by volume based on the total volume of liquid supplied to the injector, being drawn simultaneously by suction into the injector under such conditions that, in addition to immediate mixing and conversion of the reaction components substantially completely within the injector, gas dispersion and emulsifying takes place with formation of a stable non-explosive emulsion of the reaction products, which is then rapidly moved through a closed conduit to a separator house remote from the nitrating apparatus where the nitric ester produced is separated from the spent acid in a centrifugal separator.  Cooling may be applied immediately after the emulsion has left the injector. The process is exemplified with reference to the production of nitroglycerine with the use of air as the added gas.  Specification 735,888 is referred to.

Title: Switch apparatus including a pair of beam-type switches
Inventor: HERMAN JEFFREY G
IPC: H03K17/94
Filed: 1989-11-08
Granted: 1996-01-02
Abstract: A  manually operable  switch  apparatus for  a machine having at  least one mode of operation actuated by a control circuit includes a spaced pair of switches which are simultaneously  manually operable without the application  of   exertive  contact  by   an  operator.          Preferably,  each switch  includes an  infrared emitter spaced  from  an infrared  receiver,  and  a single  or double pole, double  throw relay actuated when the beam between the emitter  and receivers are broken, so as to cause  actuation  of  an  alternative mode  of  machine operation.   The use of  switches which do  not require exertive  contact  obviates  the  injury to  wrist  and finger  tendons experienced  by machine  operators when conventional  palm  buttons  are employed  on  machines requiring repetitive  operator manipulations.   The use of  a spaced  pair of such  switches requires  that the operator place  both hands on the  switches in order to operate  the  machine,  so  that  the  operator  cannot inadvertently  place  a  hand  in  or adjacent  to  the machine  during  operation,  thus  serving  to  prevent injury  to the  worker.   Such  a  switch apparatus  is substantially    more   reliable    than   conventional mechanical   and   pneumatic   switches,   subject   to significantly less breakdown in use.

Title: Guided-wave optical branching components and optical switches
Inventor: KAWACHI MASAO
IPC: G02B6/12
Filed: 1990-02-05
Granted: 1995-02-28
Abstract: A guided-wave optical branching component composed of Mach-Zehnder interferometer having two or more directional couplers.  A slight difference .DELTA.L in the optical-path length is given to the two or more optical waveguides connecting the two or more directional couplers.  The difference of the optical-path length is determined less than the shortest wavelength in the operational wavelength region of the guided-wave optical branching component, and a coupling ratio of each of the two directional couplers is determined to monotonically increase according to the wavelength in the operational wavelength region.  By using the optical branching components thus constructed (i.e., Mach-Zehnder interferometer type 3-dB optical coupler) in conjunction with a phase shifter, Mach-Zehnder interferometer type optical switch can be achieved.

Title: Ultrasonic power supply
Inventor: ROBERTS ALLAN J
IPC: H03L7/06
Filed: 1990-04-11
Granted: 1995-07-25
Abstract: An ultrasonic power supply for driving a piezoelectric transducer at its parallel resonant frequency includes a clamped-mode resonant converter for converting direct current to alternating current and a demodulator, a loop filter and a voltage controlled oscillator in a phase locked loop configuration. The power supply also includes a control circuit for adjustably setting and controlling the amplitude of vibration of the transducer, and providing during start-up a ramp start. The power supply, further, includes a control circuit for limiting the maximum permissiblecurrent flow to the transducer and the reverse current flow from the transducer resulting from stored mechanical energy. Both control circuits provide feedback signals which control the pulse width modulated operation of the clamped-mode resonant converter and thereby control the voltage amplitude of the alternating current output from the converter. The phase locked loop circuit causes the frequency of the alternating current output from the converter to track the parallel resonant frequency of the transducer.
