Patent CA-2018484-A1 (CA)
Inventor: VEZAIN GERARD
IPC: F16B1/00
Filed: 1990-06-07
Abstract: ABSTRACT OF THE DISCLOSURE     So  as to temporarily connect  two elements, such as an  artificial satellite lengthening piece  and the body of this  satellite, a device is used including a holding mechanism  (22) of  any structure  and a  freeing member (20)  made  of  a  form  memory  material.  The  holding mechanism  (22)  normally applies  a holding  mechanical tension  between  the elements.  When it  is desired  to free  these elements, the freeing  member (20) is heated by,  for example,  a heating resistor  (28) or  by using solar  energy,   until  it  reaches  the  transformation temperature   of   the   form   memory   material.   The disposition of  the freeing member (20) is such that its change   of  form  suppresses  the   mechanical  holding tension and creates  a positive  allowance between  the elements.

Title: Load cell mounting for rotational control
Inventor: MILLS NIGEL G
IPC: G01G21/23
Filed: 1990-07-11
Abstract: Load cells incorporating rocker pin configured columnar central structures within a weighing system have the attribute of self-erecting upon being displaced from a vertical orientation due to dynamic transverse loading effects, as may be occasioned by vehicle movements onto a scale. The resultant transient vector forces thus developed have been observed to cause a rotational phenomenon in the rocker pin configured cells which causes unacceptable damage to the instrumentation control communication components of the load cell system. A mounting technique for such load cells is developed wherein only these rotation inducing forces are restrained, while the vertical force vectors representing valid load data are maintained in an unrestricted or uncompromised manner. In one aspect of the invention, a hexagonal form of mounting between a rocker pin neck-contact surface region and a corresponding receiver cavity achieves a fully pivoting and freely abutting contact geometry while effecting the noted restriction of rotation. In another aspect, a resilient device such as spring is loaded during restricted rotational movement of the load cell and released at the termination of the transient rotational forces to return the load cells to their initial orientation while the load cells remain under load induced compression.

IPC: H04B1/16
Filed: 1990-10-11
Abstract: A digital communication system has a plurality of channels with distinct carrier frequencies and overlapping bands. Each receiver includes a filter having a time varying bandwidth. The received signal includes at least one carrier modulated by an information signal having a plurality of levels and transitions between the levels at predetermined intervals and components due to other channels. The receiver is synchronized to a selected one of the carriers. The received signal is translated to baseband and applied to the time varying filter which is set to a first bandwidth at the information signal transitions and reduced in the intervals between transitions. The first filter bandwidth accommodates the information signal transitions. Reducing the bandwidth between transitions limits interference components in the time varying filter output when the the information signal level is sampled. The technique may be applied to various modulation schemes.

Abstract: Autoimmune diseases can be treated by administering T cells which are specific to a T cell receptor which is present on activated T cells but which is not present on non-activated T cells and which T cells are non-specific for the T cell receptor which is specific for the target protein of the autoimmune disease being treated. Such a T cell receptor is referred to as an ergotope as it is a marker of activation. Autoimmune diseases can also be treated by administering ergotypic T cells, fragments or proteins which include or comprise an ergotope. Such ergotypic T cells, fragments and proteins will serve to raise T cells which are specific to an ergotope in vivo and will thus attack the natural ergotopes on the autoimmune T cells.

Title: Buckle unit
Inventor: NANBU YUICHI
IPC: A44B11/25
Filed: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE    When the connection of the buckle main body A with the tongue 1 is to be released during normal operation, the operating member 7 is operated and is moved to the position where the engagement of the tongue 1 with the latch member 5 can be released.  In this case, the locking member can be moved toward the position where the engagement of the tongue with the latch member can be released, and the locking member is perfectly moved to the position where the engage-ment of the tongue with the latch member can be released by the operating member.    When impact is applied on the buckle unit, the control means prevent the locking member from moving toward the position where the engagement of the tongue with the latch member can be released.  For this reason, the engagement of the tongue with the latch member cannot be released, and the connection of the buckle main body with the tongue can be perfectly maintained.
