Inventor: ACKERET PETER
IPC: G03B29/00
Filed: 1980-04-15
Granted: 1984-07-31
Abstract: The picture viewer has a housing that accommodates a pile of pictures, of which the uppermost lies beneath a housing window. The viewer has a sliding mechanism that may be pulled out of the housing and inserted parallel to the viewing window.

Title: Method for feeding a plurality of untethered animals
Inventor: BLICHER STEEN
IPC: A01K7/00
Filed: 1980-08-14
Granted: 1983-09-15
Abstract: An equipment for feeding was described.  Generally, swine in the same age are brought up in the same pigsty.  In this environment, each animal is various in weight and cannot be send to a slaughterhouse at the same time.  To some extent, it is caused by an inherited character, but, chiefly, caused by struggle for fodder.  To minimize the weight variation of each unthethered animal and to grow it healthy, the equipment which controls each quantity of fodder components and feeding rate was developed.  In the system, dried fodders which contains the components necessary for growth and liquid which contains standard nutrient soln and water are supplied separately.

Abstract: Method uses circular loom. Each leno warp thread(Y2) passes from a guide(45) to a gage ring(46) via an eye(41a) in the top of a spring- loaded skeleton heald(39) whose legs respectively pass through the eyes(37a, 38a) of inner and outer standard healds(37, 38) that are oppositely movable up and down. The ground warp thread(Y1) goes from the guide(45), between the skeleton heald and the inner and outer standard healds, through a pair of rods(47) fixed to guides(14,16) for shuttles(13), optionally under a roll(14), and then to the gage ring. Ground warp threads only move around the tops of skeleton healds, from and to a generally straight-line position,  warp thread intertwining being effected mainly by leno warp movement.

Title: Steam turbine control
Inventor: WAGNER JAMES B
IPC: F01D17/24
Filed: 1981-09-15
Granted: 1988-07-02
Abstract: Two transducers provide signals proportional to plessure in a steam pipe to summing amplifiers.  Thease are switched in circuit by a logic circuit to permit automatic control of a diverter valve in place of manual control.  This valve is positioned by a reference value at a comparator.  The turbine speed is sensed by transducers and is calculated in a loading and speed control circuit whose output is transferred to a summing circuit.  A low pressure valve gate provides a control signal for the main control valve.  A comparator provides a warning signal for the gate to provide a valve closure signal for a turbine speed above a predetermined upper limit.

Title: Steerable railway truck
Inventor: HERRING JAMES MORTON JR
IPC: B61F5/32
Filed: 1981-10-12
Granted: 1988-05-26
Abstract: The journal boxes are disposed to slide up and down within the ends of the side frames of the truck.  The loads applied to the wheels of the car are transmitted through the axles and journal boxes to the equalizer beams.  The equalizer beams bring the load over equalizer springs.  Equalizer beams are used so that, during travel, if one wheel is lifted, the load will not change much.  The equalizer beams and springs equalize the vertical loads on the wheels.  An arrangement having a rigid frame and equalizer means makes it extremely difficult to provide a truck with selfsteering.

Title: Process for preparing parts by means of forging powder
Inventor: MANFRED WEBER
IPC: B22F5/00
Filed: 1989-02-04
Granted: 1996-10-10
Abstract: Powder-forged components consisting of two individual parts are pressed from a one-piece powder preform to give the final form, sintered, forged, cooled and divided into their individual parts. The object on which the invention is based is to considerably simplify this process and simultaneously to make possible accurately fitting production of the individual parts. 
<??>This object is achieved according to the invention by the fact that, prior to sintering, the preform is provided at the division between two individual parts with at least one shallow notch. Between sintering and forging, the notch receives a protective layer, in particular an oxide layer and, during forging is closed to give the final form. After cooling, the component is broken into its individual parts. 
<??>The process according to the invention can be used, for example, for the production of a connecting rod (16) with a divided small end (13). After the cooling of the connecting rod, the holes for the connecting rod bolts (17) are made in the small end, connecting rod bolts and connecting rod nuts are mounted loosely in the holes and the parting face is subsequently produced in the seam of the small end.
