Inventor: ANDERSON JOSEPH A
IPC: E05B63/14
Filed: 1992-01-17
Abstract: ABSTRACT OF THE DISCLOSURE A door lock for preventing unauthorized ingress and solely actuable from the inside of a room. The lock includes a lock bar, pivotally anchored to the outer edge of the door, and a jamb plate, anchored to the adjacent jamb and having an elongated vertical aperture for door locking engagement by the lock bar free end portion when the door is closed. A stem is slidably mounted on or within the lock bar to take a blocking position protruding beyond the free end portion of the lock bar and releasably extending through the jamb plate aperture. When the stem is engaged into the jamb plate aperture, the lock bar is prevented from pivoting because the stem has no clearance to do so within the aperture. Thus, a person outside the room could not release the lock bar by upward pivotal thereof, for instance by inserting a blade through the vertical air gap between the door outer edge and the jamb plate, underneath the lock bar, and then lifting same.

Title: Automatic volume control system
Inventor: MOFFATT JOHN K
IPC: H04S7/00
Filed: 1992-04-29
Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to an automatic volume control system which adjusts the level of an audio electrical signal in dependence on ambient noise level.  A filter derives low frequency components from the audio signals and these components are then applied to a gate where they are intermittently gated.  An electrical signal produced from ambient noise detected by a sensor is sampled by a further gate    during the gating periods and a sam-pled level of the noise signal is maintained from one gating period until the next gating period and is applied to a gain control circuit to control the level of the audio electrical signal in dependence on each sampled level of the noise signal.  The gating and sampling actions prefera-bly occur at irregular time intervals under the control of a logic and timing circuit assessing circuit and clock.

IPC: B65D90/02
Filed: 1990-11-15
Abstract: An insulating panel (15) is disclosed having an outer, continuous membrane (22) supported by an internal rigid frame (33). The continuous membrane (22) encloses a vacuum space, and is made up of top (23) and bottom (26) membrane sections each having a plurality of biaxially curved, concave surfaces (30) which are loaded in tension when exposed to ambient atmospheric pressure. Between each biaxially curved, concave surface (30) is an arcuate path (99) which enables differential tension loadings on the adjacent biaxially curved, concave surfaces (30) to be offset. In this manner, resultant tension stress loadings on opposite panel surfaces may be offset, thereby reducing the structural requirements of the internal rigid frame (33). In another embodiment, an expansion joint means (50) is manufactured along the top (23) or bottom (26) membrane sections which enable the sections to maintain their tension stress loadings while undergoing thermal contraction or expansion. In other embodiments, corner (60) and container (80) shapes also disclosed herein comprising a plurality of panels (15) joined together.

Filed: 1991-12-12
Abstract: Des zones de soluté ampholyte qui ont été stabilisées par concentration isoélectrique dans un milieu de séparation tel qu'un capillaire sont mobilisées par l'introduction d'une quantité relativement grande de zwitterions dans l'une des chambres d'électrode. Quand une tension est alors appliquée entre les chambres d'électrode, comme c'est le cas dans la phase de concentration, les zwitterions pénètrent dans le milieu de séparation selon leur point isoélectrique. Cette tension est maintenue pour entretenir une migration continue des zwitterions dans le capillaire et former ainsi une zone en expansion qui déplace les zones de concentration formées dans la phase de concentration et les oblige à avancer axialement dans le capillaire vers un point de détection ou à sortir du capillaire pour fins de récupération.

Abstract: An apparatus for dispensing product from a container in which first and second members are provided in a vessel which is disposed in the container.  The first member defines with the vessel a first chamber, and the second member defines with the first member a second chamber.  One of the members moves in response to the pressure in the container to a first position relative to the other member and pressure is exerted in the second chamber on said first member to move it to a second position in response to the pressure in the container decreasing below the predetermined pressure.  When the first member moves to the second position the first chamber is connected with the container to permit the pressurized gas in the first chamber to pass to the container and when the first member moves to the first position this connection is disconnected to prevent the passage of the gas.
