Patent DE-3907832-A1 (DE)
Inventor: DALLMER JOHANNES DIPL ING
IPC: E03F5/04
Filed: 1989-03-10
Abstract: PCT No. PCT/EP90/00160 Sec. 371 Date Nov. 7, 1990 Sec. 102(e) Date Nov. 7, 1990 PCT Filed Jan. 12, 1990 PCT Pub. No. WO90/10761 PCT Pub. Date Sep. 20, 1990.The surface drain has a cup-shaped drain body (14) which is securely cast into a concrete slab (10). A cylindrical inset (20) in form of a disk is fitted in the concrete slab and rotatable about the axis of the drain body. Fitted in the disk is also a rotatable cylindrical part (31) of a square frame (30) which receives a grate. When laying the tiles, the square sides of the grate frame can be set parallel to the joints of the tiles by turning the grate frame. Since the cylindrical inset (20) has an eccentric inner cylinder (24) for receiving the cylinder (31), a turning of the cylindrical inset in the concrete slab permits the square sides of the grate to coincide with the coordinates of the tile joints.

Title: Yarn braking unit for sectional warping machine - with guide roll with stationary bearing and press roll with movable bearing
Inventor: BOMMER GUIDO
IPC: D02H13/22
Filed: 1989-07-18
Abstract: An installation for braking yarns or similar prod. for sectional warping machines consists of two rotating rolls:  a guide roll on a mounting with a stationary bearing and a press roll with a movable bearing. An opening device, e.g. a tiltable lever, is located on the press roll and acts in conjunction with the movable bearing of the press roll in such a way that the press roll can be lifted from the guide roll against the press roll when the lever is operated.

Title: Supplying products to packaging machine - using variable speed belts and sensors to monitor product position and initiate brief acceleration to items
Inventor: HAISS MANFRED
IPC: B65G47/31
Filed: 1990-01-31
Abstract: The method accelerates the products (1) on a conveyor (13) in order to separate them. This acceleration is only brief and is followed by conveyance at constant speed to a moving carrier arrangement (20) with which the products are passed to the conveyor (13). After having been transferred to the conveyor, the products are initially carried at the same speed unaltered. In the region before acceleration on the conveyor, the products experience suction. A second conveyor (13) may adjoin a first (3) and may have variable speed w.r.t. the first. The speeds of both conveyors depend on the speed of the packaging machine. A sensor (26) monitors product position. Another sensor (27) controls product acceleration. ADVANTAGE - Trouble-free separation of products from stream.

Patent DE-4026912-A1 (DE)
Inventor: BEALKOWSKI RICHARD
IPC: G06F21/12
Filed: 1990-08-25
Abstract: An apparatus and method for protecting BIOS stored on a direct access storage device (62) into a personal computer system (10). The personal computer system (JO) comprises a system processor (26), a system planar (24), a random access main memory (32), a read only memory (36), a protection means and at least one direct access storage device (62). The read only memory (36) includes a first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS initializes the system (10) and the direct access storage device (62), and resets the protection means in order to read in a master boot record into the random access memory (32) from a protectable partition on the direct access storage device (62). The master boot record includes a data segment and an executable code segment. The data segment includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment of the master boot record agrees with the system processor (26), system planar (24), and planar (24) I/O configuration. If the master boot record is compatible with the system hardware, the first BIOS portion vectors the system processor (26) to execute the executable code segment of the master boot record. The executable code segment confirms that the system configuration has not changed and loads in the remaining BIOS portion from the same protectable partition on the direct access storage device (62) into random access memory (32). The executable code segment then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the BIOS now in random access memory. BIOS, executing in random access memory (32), then activates the protection means to prevent further access to the protectable partition. BIOS boots up the operating system to begin operation of the personal computer system.
