Patent EP-4235727-A1 (EP)
Inventor: GOMBERG BRYON
IPC: H01H50/32
Filed: 2023-02-16
Abstract: An electromechanical relay may comprise a housing and one or more terminal pairs. Each terminal pair may comprise a first terminal connected to a first contact, a second terminal connected to a second contact, a first armature connected to a first coil and coupled to the first contact, and/or a second armature connected to a second coil and coupled to the second contact. Supplying power to the first and the second coils may enable movements of the first and the second contacts by moving the first and the second armatures, thereby resulting in an electrical connection between the first and the second contacts. Removing the power may comprise the first contact to be isolated from the second contact. A central armature lock may be inserted through the housing and into the recesses of each of the first and second armatures, which may reduce movement of the armatures.

Title: Antenna and communication device
Inventor: YU MIN
IPC: H01Q13/10
Filed: 2023-03-03
Abstract: An antenna and a communication device are disclosed. The antenna may be used in an access point. The antenna specifically includes a first conductor sheet and a feed point. The first conductor sheet includes at least two cavities. The at least two cavities are connected through a gap. A circumference of each of the at least two cavities approaches a wavelength corresponding to an operating frequency band of the antenna. The feed point is connected to the gap. The antenna with a simple structure and a small size may generate two beams. Therefore, an access point disposed with the antenna may generate strong wireless signals in two directions, and the wireless signal may cover an adjacent room. In this way, there is no need to deploy an access point in each room, and a quantity of wireless access points to be deployed is reduced.

Abstract: A method for preparing high activity supported nickel catalysts comprises depositing nickel nitrate on a support (which is either an inorganic refractory oxide, e.g. alumina or silica-alumina, or carbon), heating the resulting composite in a flowing gaseous atmosphere to a temperature either in the range of from 100-270 DEG C when the atmosphere is substantially free of molecular hydrogen, or in the range 100-220 DEG C when the atmosphere contains molecular hydrogen, avoiding temperature excursions above the stated maxima. The heating decomposes nickel nitrate to the oxide and the resulting supported nickel oxide is then reduced to nickel in a reducing atmosphere at a temperature in the range 230-400 DEG C to produce the high activity supported nickel catalyst. 
<??>The hydrogenation activity of the catalyst is considerably higher than that of prior supported nickel catalysts having the same nickel surface area per unit weight.

Abstract: A prosthetic cement spacer (20) for controlling the thickness of cement applied between a prosthetic insert and a support member, such as an acetabulum, includes a generally cylindrical standoff body portion (21) fabricated from acrylic bone cement and a pointed wire (22) concentric with said standoff body and outwardly extending from one end a sufficient length to anchor into the acetabulum bone surface. The method of use of these prosthetic cement spacers involves preparation of the acetabulum so that there is sufficient clearance space for the prosthetic cement spacers and then to insert the pointed wires into the acetabulum bone surface in an equilateral triangular arrangement thereby providing three points of contact for the prosthetic insert, such as an acetabular cup. By selecting three prosthetic cement spacers all having substantially the same standoff body height, the clearance region between the acetabulum bone surface and the acetabular cup is controlled and provides a uniform cement thickness throughout thereby providing an improved bonding arrangement.

Inventor: MOLITOR VICTOR D
IPC: F28F9/00
Filed: 1980-05-16
Abstract: A method of producing a multiple coil, multiple tube heat exchanger from circular tubes, in which alternating turns in each coil have a warmer liquid and other turns a cooler liquid, by coating the outside of each coil (C<u1>u) with a heat conductive mastic and winding the next coil (C<u2>u) against the mastic to force the mastic into spaces between adjoining tubes of the first coil, into spaces of adjoining tubes of the second coil, and into spaces between opposed tubes of the first and second coils. Mastic (34) is applied to the outside of each coil or into grooves between turns as the next coil is wound. Double tubes of each coil are preferably wound into grooves between turns of preceding coil, with the second tube of each coil started across coil from the first tube and continued at end of the coil past the first tube. Succeeding coils are wound against the mastic in same manner. Turns of the first coil (C<u1>u) are attached together, as by soldering, while the first and last turns of succeeding coils are similarily attached to adjacent turns of the coil beneath. Succeeding coils (C<u2>u) may be terminated between second and third turns of coil beneath, or with appropriate inner diameter of the first coil (C<u1>u), terminated between the last two turns of coil beneath. Several coils may be formed of tubing of the same diameter, with additional coils of tubing of greater diameter, all coils of tubing of same diameter, or all coils of tubing of successively increasing diameter. Length of the coils proportioned with respect to diameter of tubing so that the liquid will take the same amount of time to flow from one end of each coil to the other.
