Title: Method and apparatus for raising ruminants
Inventor: NAGAMORI SYOTARO
IPC: A61D7/00
Filed: 1991-11-12
Abstract: A gastric resident object having elastic stimulus members, which is admitted into the rumen, functions as a substitute for roughhage and stimulates the mucous membrane and the wall of the rumen, so that the rumen can be maintained healthily and appropriately.  Thus, it is possible to lessen the use of roughhage in quantity and decrease the excretion, to thereby curtail the costs for dealing with the excretion and feeding for the ruminants.

Title: Pickup coil for measurement of magnetic fields
Inventor: KAJOLA MATTI J
IPC: G01R15/14
Filed: 1991-12-10
Abstract: The invention concerns a pickup coil to measure com-ponents of gradients. The coil consists of two pairs of loops connected in series; these pairs are then connected in parallel. The coil so formed has a low inductance, and no shielding currents are induced to superconducting coils in homogeneous magnetic fields. One coil can be employed to measure several field components simul-taneously when the coil is coupled to current sensing elements, for example to SQUIDs, so that the current components measured by the sensing elements do not couple magnetically because of the symmetry. This can be accomplished by connecting the said elements be-tween terminals between the loops (5, 6 and 7, 8). The inductance of this coil can be further reduced by subdi-viding the loops into party connected in parallel.

Patent CA-2065165-A1 (CA)
Title: Gear pump having internal bypass valve
Inventor: ELEY JAMES M
IPC: F04B49/00
Filed: 1992-04-06
Abstract: ABSTRACT OF THE DISCLOSURE A continuously driven gear pump includes an internal bypass valve for selectively controlling the supply of pressurized fluid to a hydraulically actuated device.  The internal bypass valve includes a movable spool which is spring-biased to a first position, wherein the flow of fluid is bypassed from the outlet port back to the inlet port, and no fluid is delivered to the actuated device. The spool has an internal passageway formed therethrough which permits a relatively small amount of fluid to pass from the outlet port back to the reservoir when the gear pump is operated in the bypass mode.  To replenish this small amount of fluid which is returned to the reservoir from the outlet port, the gear pump draws a corresponding small amount of fluid to the inlet port.  Thus, a small amount of fluid circulates between the gear pump and the reservoir when the gear pump is operated in the bypass mode.  This circulation cools the pump without causing a significant load to be placed on the engine.  The spool can be moved to a second position against the urging of the spring, wherein the entire flow of fluid is directed to the actuated device.

Abstract: ABSTRACT TO THE DISCLOSURE So  as to rapidly introduce sterile objects (B) into an  excess  pressure isolator,  the  latter is  equipped with at  least one device including a slanted guide tube (38)  whose lower extremity normally  communicates via a door  (18) which is  normally closed. The objects  to be introduced  and protected by closed  bags, are placed on a receptacle  (40) situated opposite the upper extremity of  the guide tube (38). This  receptacle and the inside of  the guide tube are scavenged by  a clean air current derived  from  a  ventilation box  so  that the  sterile nature of  the objects is retained when their bag is cut from the  receptacle. This receptacle is then slanted so that  the objects fall  into the guide tube  via gravity as  far as a stop (50) situated close  to the door (18). The   objects  are  introduced  into   the  isolator  by retracting the stop (50) and opening the door (18).        Figure 1.
