Abstract: An insulating glass pane assembly and its use. The assembly includes at least two panes of glass sealingly connected to each other and held apart from each other by a crosspiece attached on the perimeters thereof. The crosspiece is provided with at least one layer of sound-reducing material attached in such a way that it prevents the transmisson of sound from pane to pane by way of the crosspiece. The assembly can be used to produce windows by providing a window pane having grooves therein disposed in such a way that they receive and retain the panes of glass within the window frame. A sound-reducing material is attached in the grooves to insulate the panes of glass on all sides against the window frame in a sound-reducing manner.

Abstract: Titanium aluminum, non-frangible structural wire, when assembled into axially symmetric and contrahelically wrapped cable has high fatigue strength and loading linearity for uniquely high work efficiency. Dynamic stresses are moderated by more suitable mechanical, physical and dynamic properties so that stress and fatigue control are passively achieved. Structural wire is specially processed from selected titanium base alloys having high drop test tear energy, wherein new construction designs and specifications are then suitable and used during cable assembly to substantially advance work performance and increase service life.Work characteristics are basically improved and changed by (1) adding elastic and constructional stretch, (2) materially reducing mass density, and (3) loading cable with hard and soft spring. These cable attributes translate into much higher fatigue strength, mainly by absorbing, storing and dissipating induced work loads at rapid rates.

Abstract: An anti-sweat refrigerator cabinet warming device including a secondary refrigerant loop heat transfer arrangement extending through the refrigerator cabinet to warm those portions which have a tendency to form condensate on the exterior surfaces. The secondary loop is warmed by thermal contact with the condenser loop of the refrigeration system, which thermal contact is selectively controllable by positioning of a control member to position a section of the secondary loop and the condenser loop into and out of thermal contact. This is accomplished by a clamp acting on the loop sections, operated by a manual control lever to allow the selective operation of the heat transfer device. This allows power conservation when the warming of the cabinet is not required to prevent condensate formation. The clamping device is designed to maximize the transfer of heat from the condenser loop section into the secondary loop section when the cabinet is being warmed.

Abstract: A spray generator for an absorption refrigeration system that includes a heat exchanger comprised of a multiplicity of variably spaced heat exchange tubes. The tubes are spaced close together near the top of the heat exchanger and spaced more widely apart near the bottom of the heat exchanger. Dilute absorbent solution is sprayed down through the heat exchanger. The close nesting of the tubes in the top portion of the heat exchanger retards liquid flow and aids heating of the solution. The wide spacing of the tubes in the lower section of the heat exchanger facilitate vapor flow out of the heat exchanger and eliminates liquid "blow-off". The top tubes are covered by a baffle to prevent the liquid solution from splashing out of the heat exchanger off of these top tubes.
