Title: Seed boot
Inventor: SCHIMKE HARVEY
IPC: A01C7/08
Filed: 1988-08-12
Granted: 1990-11-27
Abstract: SEED BOOT          ABSTRACT OF THE DISCLOSURE         A seed boot for air seeders includes a cast hol-low body having a relatively narrow cylindrical upper end intake into which a seed tube may be clamped.  Vertically spaced apart transverse ribs or steps are situated one on the front wall and one on the rear wall of the interior of the body to equal distribution of the seed regardless of the angle at which the tube enters the boot.   Spreaders may be secured to the bottom or discharge end of the boot and can be used to adjust the spread pattern of the seed and an air release slot or vent is provided in the rear wall of the body to reduce air pressure thus reducing the speed at which the seed strikes the ground thereby reduc-ing bounce.  A rear strut may be provided at the rear of the boot to accommodate a banding knife if desired,  to permit seeding and fertilizer banding in one operation.

Title: Paging system with transmission protocol compatible with analog and digital transmitters
Inventor: ANDROS ANDREW A
IPC: G08B5/22
Filed: 1988-10-18
Granted: 1992-06-23
Abstract: Paging System With Transmission Protocol Compatible With Analog and Digital transmitters Abstract A paging network (10) is disclosed which utilizes a plurality of distributed switches (12, 14 and 16) to transmit pages on a non-real time basis to achieve efficient and low cost transmission.  Each of the switches processes packets of pages received from the network.   Each of the switches also processes pages  into packets of pages to be transmitted to another switch in the network or into batches of pages to be transmitted by a local paging service if the  switch  is  a  local  switch.   The  network dynamically programs the reception frequency of the paging receivers in response to traffic conditions of a local switch or in accordance with service options specified by a subscriber to a local paging service. The digits of the paging receiver identification code are  transmitted  in  an  order  of  increasing significance to conserve battery life of the paging receivers.  Pages may be initiated by placing a local call to any lata switch in the network and service options may be varied by placing of a local call to a lata switch.

Title: Crossbar assembly
Inventor: MCKEE JERE L
IPC: H01H9/38
Filed: 1989-07-14
Granted: 1994-09-20
Abstract: CROSSBAR ASSEMBLY Abstract of the Invention A crossbar assembly is formed from an elon-gated metal bar.  A pair of contact arm carriers are slid onto the metal bar and welded in place.  Molded electrically  insulated sleeves  are sliding received at each end of the crossbar.   The insulated sleeves can  be  either  molded  directly  on  the  crossbar  or molded  separately,  in which  case,  the  sleeves  are glued with epoxy and pinned to the crossbar to pre-vent axial movement of the sleeves with respect to the crossbar.   The insulated sleeves are formed with a pair of plates disposed at each end.  A pair of op-positely disposed slots formed in the plates is used to  receive  the  ends  of  a  cam  roll  pin  assembly. Since the crossbar in accordance with the present in-vention  does  not  require  wrapping  with  insulating paper,  the possibility of dielectric failure due to cracking  of  the  insulating  paper  is  eliminated. Also,  since the contact arm carriers are welded to the crossbar instead of being stapled, the possibili-ty of axial movement of the contact arm carriers dur-ing overcurrent conditions due to loose staples is also eliminated.

Abstract: OVAL WRAP SUTURE PACKAGE      Abstract of the Disclosure:     A molded two-piece suture package is disclosed which encloses and defines an oval channel in which sutures may be wound.  The oval channel has two semicircular end sections connected by straight side sections.  An opening in the channel is provided at the juncture of a straight section and an end section, permitting sutures to be withdrawn from the channel at the end of a straight section.  In a preferred embodiment the interior wall of the channel is formed by alternating engaging sections formed in the respective package pieces.  To prevent the wrapped suture from becoming entrapped when the two pieces are engaged, the top and bottom of the channel is alternately raised and lowered in alignment with the alternating wall sections, causing the wound suture to bridge those areas where it may become entrapped between the mating package pieces.   Entrapment of the suture end at the outside of the channel is prevented by alternately recessing the outer wall of the channel.  Flexible molded needle parks are also disclosed for the package.

Abstract: The assembly starts from horizontal bulkheads to which are secured vertical pairs of sections. To mechanise the operation, once the cross bulkhead has been installed at the assembly station, a first section is installed vertically and connected to the bulkhead. The assembly is then turned round a vertical axis and a section (3) of the second pair is fitted and then turned once again to fit a third section. A final turn is used for fitting the final section completing the module. - The support platform (7) with a tilting platform (13) may be supplemented by a second platform (20) which moves up and down and also rotates round a vertical axis of symmetry and is moved by bogies (8) forming part of the main platform (7). The tilting platform clamps (25,26) move in three mutually perpendicular directions to move the section across and along the tilting platform and lift and lower it relative to this. Segments (14) at right angles to the tilting platform base, facing the second platform, work with rollers (17) on rods (16) forming part of hydraulic power cylinders (15) used to drive the tilting platform.(14)

Abstract: A system for regenerating a standard-length color burst signal from a less-than-standard-length color burst information signal of a given frequency and phase. The system includes a phase-locked loop (20) for generating a system clock signal(46) from the color burst information signal (42), with the clock signal having a clock frequency related to and at least twice the given frequency of the color burst information signal. The phase information from the color burst information signal is sampled and stored in a RAM (26). The sampling is clocked by the system clock signal. A standard-length color burst signal (58) is regenerated at the given frequency and in phase with the color burst information signal by retrieving the stored phase information and extrapolating the standard-length signal in accordance with the retrieved phase information. Such retrieval is clocked by the system signal. The phase-locked loop is a digital phase-locked loop; and the color burst information signal is converted into a digital color burst information signal for processing by the phase-locked loop and for sampling and retrieval of the phase information. Upon retrieval and extrapolation of the phase information samples, the retrieved and extrapolated phase information samples (54) are converted into an analog sample information signal (56), which is converted into a regenerated sinusoidal standard-length color burst signal (58) by a low pass filter (34).

Abstract: A temperature attenuator (32, 42 or 64) is provided for spacing a container, such as a coffee container (24), from a warming hot plate (14 or 14').  The temperature attenuator has a thermally insulating spacer (34, 66 or 66') which may be secured to the container or to the hot plate by an adhesive (70), by a harness (44) or any other suitable retainer.  The spacer (34, 66 or 66') is of closed peripheral configuration, for example, it may be an O-ring or gasket ring, so that heated air is trapped in an enclosed space(s) sealed between the container bottom and the hot plate.  Hot spots which otherwise would result from direct contact of the container (24) with the hot plate (14) are thus avoided and beverages such as coffee may be heated for protracted periods without developing an acrid taste.  A method of heating the container contents includes spacing the container by means of the spacer about 1/32nd to 1/8th of an inch (about 0.8 to 3.2 mm) from the heating surface (14s) of the hot plate, and maintaining the hot plate at an elevated temperature of from about 200°F to 450°F (about 93°C to 232°C).
