Patent CA-2151865-A1 (CA)
Title: Cooling apparatus for turbine shrouds
Inventor: CORREIA VICTOR H S
IPC: F01D11/08
Filed: 1995-06-15
Abstract: A turbine shroud includes a plurality of cavities for receiving cooling steam for flow through the cavities in series counterflow to the direction of the hot gases of combustion. In the first cavity, a projection forms a nozzle to increase the velocity of the cooling steam to increase the convection coefficient for cooling the wall of the shroud. The steam flow in the second cavity passes through an impingement plate for impingement cooling of the wall of the shroud. Likewise, steam passes from the second cavity into the third cavity for flow through an impingement plate for further impingement cooling of the wall of the shroud. In the second and third cavities, the impingement plates include a plurality of ducts affording increased flow area in the direction of travel of the post-impingement steam flow to reduce cross-flow effects.

Title: Method for controlling the microwave feed in a microwave oven, and microwave oven with such control
Inventor: IDEBRO MATS GUNNAR
IPC: H05B6/74
Filed: 1995-06-28
Abstract: A method for controlling the microwave feed in a microwave oven, as well as a microwave oven for imple-menting the method, is disclosed. The power level (P) of the microwaves is controlled by periodic activation or inactivation of the microwave radiation source of the oven during a sequence of control cycles. The oven has a rotary bottom plate (4) carrying the food or dish, and/or a rotary field agitator or aerial. The heating uniformity is improved by adjusting to one another the duration of the control cycle and the revolution time of the bottom plate or of the field agitator or aerial, while taking into consideration the aimed-at power level. In a pro-cedure composed of several steps with different power levels and heating times, the heating times of the diffe-rent steps are also adjusted to the current control-cycle duration. (Fig. 1)

Abstract: A needle point barrier includes a resiliently deflectable spring arm, a link arm and a barrier arm. The proximal end of the spring arm is secured near the proximal end of the needle. The link arm has one end hingedly connected to the spring arm and an opposed end hingedly connected to a proximal position on the barrier arm. Distal portions of the barrier arm slidably engage the needle. The needle point barrier can be collapsed into a Z-shaped configuration near the proximal end of the needle. The barrier arm can be urged distally by force applied to the proximal end of the barrier arm. Initial movement of the barrier arm willdeflect the spring arm away from the needle. After sufficient manual movement ofthe barrier arm, the resiliency of the spring arm will urge the barrier arm distally into shielding relationship with the distal end of the needle.

Inventor: SCHELDRUP RONALD W
IPC: A61B17/00
Filed: 1995-03-02
Abstract: This invention is a method for ensuring for endovascular occlusion, aneurysms, vascular malformations, and arteriovenous fistulas. In particular, it deals with a method to predictably determine the instant of electrolytic detachment of an embolic device (104) which is introduced to and is intended to remain at the desired thrombus formation site. The invention further includes a method for delivering an embolic device (104) and detecting its electrolytic separation. According to the present invention, DC power with AC superposition (170) is delivered to the sacrificial link (106) that couples a delivery member (e.g., a guide wire) to an occlusion device. The impedance (as measured by the amplitude of the superposed AC) is monitored. When a predetermined change inthat impedance (or amplitude) occurs, which indicates coil detachment, the DC power is interrupted to minimize or avoid further electrolysis.

Inventor: CAPPELLI GUIDO G
IPC: H01P5/08
Filed: 1996-02-08
Abstract: A dual switch for coupling a waveguide microwave switch to a coaxial microwave switch. The waveguide microwave switch has a waveguide hollow member and a waveguide rotating section rotatably mounted about a rotational axis within the waveguide hollow member at one end. The coaxial microwave switch has a coaxial hollow member adjacent to the one end of the waveguide hollow member and a coaxial rotating section rotatably mounted within the coaxial hollow member about an axis coaxial with the rotational axis. The waveguide microwave switch is coupled to the coaxial microwave switch by at least one set of cooperating magnets fastened at a given radial distance from the rotational axis to the waveguide rotating section and the coaxial rotating section respectively, such that any rotation of the waveguide rotating section about the rotational axis will be followed by a corresponding rotation about the rotational axis of the coaxial rotating section. The set of magnets includes two magnets located radially opposite each other on the waveguide rotating section near its end and two pairs of magnets located radially opposite each other on the coaxial rotating section so that the magnets are centered between the pairs of magnets and repulse each other. This eliminates any openings between the waveguide microwave switch and the coaxial microwave switch and thus any radio-frequency leakage between the two switches.

IPC: H03M7/20
Filed: 1995-07-07
Abstract: In the present invention, a partly duplexed conversion table is used as a conversion table for converting an M-bit based data string directly into an N-bit based code string without using margin bits. This conversion table is constituted by first and second sub-tables including plural code groups, respectively.      The plural code groups include different codes for the same input data. The second sub-table is a table which is partly duplexed with the first sub-table and is produced by allocating different codes to data from first input data to second input data in the first sub-table. The first and second sub-tables are so designed that code sets of the duplexed portions take variants of digital sum variations which are opposite in sign. Codes are allocated to all the code groups in the duplexed portions of the first and second sub-tables with respect to input data sequentially from a code having a maximum absolute value of variant of the digital sum variation. Thus, according to the present invention, low frequency components of modulated signals may be restricted properly.

IPC: F16D65/06
Filed: 1996-07-03
Abstract: A brake shoe locking key is provided with a retention tab that is saw-tooth shaped and extends across the entire width of the key shank.  The retention tab is upraised from the shank more than the correspondingly-shaped serrations typically formed on the bottom of the key and is thus more effective in engaging the brake head as an initial detent to prevent the key from backing out of the keyhole in the brake head when a loose fitting key fails to retain its locking position.    In addition,  the retention tab  is adapted to engage the keybridge at the orifice through which the key passes in order to provide a further detent to prevent a loose key from backing completely out of its locking connection between the brake head and brake shoe, in the event the first detent fails to engage.
