Granted: 1990-04-10
Abstract: The device for forming dough balls from a filled dough rope comprises an iris assembly (12) having at least three trapezoid blades (1) and an aperture (14) defined by the blades.  The dough rope passes through the iris assembly which subdivides the rope into individual balls of filling, each having a surrounded dough crust.

Title: Multiful repressor of gene function
Inventor: BACHMAYER HELMUT
IPC: C12N5/00
Filed: 1990-05-23
Granted: 1999-08-16
Abstract: Transdominant repressors of viral gene phenotypic expression derived from the rev gene product of HIV-1 or the rex gene product of HTLV-1 and corresponding mutated genes are described', having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II. Transient gene expression analysis of a series of missense and deletion mutants has been used. Some of the mutants found repress both the Rev and the Rex function and are thus active in more than one viral species. Transdominant viral mutants represent a promising new class of anti-viral agents. Cellular expression of these transdominant inhibitors may be used in such therapeutic approaches as intracellular immunization in order to protect cells against the deleterious effects of viral, e.g. HIV-1 infection.

Title: Hose line with several parallel hoses
Inventor: ARZBERGER MAXIMILIAN
IPC: E02F5/14
Filed: 1992-06-09
Granted: 2000-06-15
Abstract: The invention relates to hose piping (17) having a plurality of parallel hoses (23) which can be wound onto a drum (20), as is used, for example, for supplying/scavenging a diaphragm wall milling tool or a similar underground-working tool. The problem exists in this case that no tension or compression may be exerted via this hose piping (17) on the apparatus which is suspended on a load cable since, otherwise, the apparatus would receive an undesirable lateral deflection. In addition, the hoses (23) must not be crushed during winding onto a drum (20). According to the invention, the hoses (23) are therefore connected to one another at predetermined longitudinal intervals by lateral webs (25) which hold the hoses (23) at predetermined lateral distances from one another. The lateral webs (25) are connected to one another in two strands (8), in a manner which is resistant to tension and is articulated, via spacers (26). During winding onto the drum (20), the spacers (26) come to rest on one another. In other respects, they are dimensioned such that the hoses (23) come to rest on one another in an unstressed manner in the individual layers. <IMAGE>

Abstract: The automatic power on method during power off of sets due to noise is provided, which includes the steps of sensing through a power source interrupt generator whether or not a microprocessor becomes power off due to peripheral bad conditions or artificial conditions, storing a final state of the microprocessor in a memory while initiating a port by inputting a reset signal through a reset part in case of power off of sets due to interrupt, comparing the data stored in the memory with a state prior to power off, automatically enabling sets to be power on through a power source controller if the data stored in the memory is equal to the state prior to power off and initiating the data stored in the memory if not, and waiting for key operation of a user.

Title: Shadow mask for stripe type color picture tube
Inventor: LEE JAE-YEUP

Granted: 1997-06-20
Abstract: A shadow mask of a CRT is described that can vary the interval of a horizontal pitch and thus satisfy a horizontal resolution and white equality at the same time. The horizontal pitch PH of a hole 16a is increased toward an edge part to the position of two thirds of horizontal length on a basis of the horizontal center part of a shadow mask 16. However, the horizontal pitch PH thereof is decreased from the two thirds position thereof to the edge part. As a result, horizontal pitch PH of the center part is less than that of the edeg part, and the horizontal pitch PH of the edge part is less than that of two thirds position thereof. Thereby, it is possible to prevent the purity at the edges of a CRT, white uniformity and horizontal resolution from being deteriorated.

Title: A control apparatus of paper machine slitter and method thereof
Inventor: KIM JAE-CHUN
IPC: D21F7/04
Filed: 1992-10-20
Granted: 1995-11-02
Abstract: The method controls the positions of more than two slitters to cut the wide paper of sizing into a desired width. Ring shape magnets respectively fixed to the upper and the lower roller are provided with a waveguide to guide the wave passing through the ring magnets to detect distorted pulses caused by the attractive force between the magnetic field generated by the electric current pulses oscillating through the wire within the waveguide and the magnetic field of the magnets to control the rotation of motors.

Abstract: 유리 기판이 상부 개구를 갖는 회전 가능한 컵 안의 대(pedestal)위에 지지된다. 유리 기판과 모양이 실질적으로 비슷한 때는 유리 기재의 하부 표면의 외부 주변 에지와맞물리기 위해, 그의 상부 표면의 외부 에지를 따라 연장하는 리지를 갖는다. 
     유리 기판 위에 도포되는 레지스트를 용액이 유리 기판의 상부 표면에 적용된 후 회전 가능한 컵의 상부 개구가 차단되고 그때 회전 가능한 컵이 회전하여, 적용된 레지스트 용액이 원심력 하에서 균일하게 퍼지게 한다.
