Abstract: ABSTRACT         A building incorporates a central heating system using a small room heater in the basement and a solar heat absorption assembly on the sunny side of the building.  The building is completely heat insulated and air ducts carry air from the basement past the solar heat assembly and into the various rooms.  The solar heat assembly also provides warm water which is stored in a tank in the basement.  As a further refinement the roof is preferably shaped as a shallow V with a central gutter which is heated by warm air from the solar heat assembly.  Snow which has collected on the roof melts only in the vicinity of the gutter and a central drain pipe running through the building carries the melted snow away without the danger of freezing.

Abstract: ABSTRACT OF THE DISCLOSURE         An arrangement for heating the service cabin of a machine driven by an internal combustion engine, includes a hydraulic pump which is driven by the engine and which pumps oil from the engine's oil reservoir and through an operating element, as for example a throttle, located between the hydraulic pump and the heat exchanger.  The heat produced in the operating element and in the hydraulic pump effects an increase in temperature of the oil before reaching a heat exchanger, located in the service cabin, through which the heated oil is returned to the oil reservoir.  The pumped oil may be selectively valved directly back into the oil reservoir for quickly heating the oil of the engine, and the hydraulic pump may be arranged for the taking of oil from the pressurized oil lines of the engine's lubricating oil distribution system rather than directly from the oil reservoir.  The oil may by-pass the heat exchanger through a pressure release valve to that the volume of oil heated by the operating element and by the hydraulic pump may be regulated to thereby regulate the temper-ature of the heat exchanger.  Moreover, if the oil is sufficient-ly heated by the engine and by the hydraulic pump, it may be made to bypass the operating element by selective valving and, valving which is provided for returning the pumped oil directly to the oil reservoir and for bypassing the operating element may be thermostatically connected to either the oil reservoir or to the heat exchanger for controlling operation of the valves depending on the change in temperature of the oil at the oil reservoir or at the heat exchanger.

The outer closure is characterized by a cap member having a top wall, a side wall and a base adapted for sealing to the neck of a container.  Two score lines extend across the top wall with finger gripping means attached at the apex where the two score lines meet. One score line extends down the side wall to connect with a third score line near the base which extends completely around the cap.  The other score line extends down the side wall to an intermediate position and diverges away and terminates a short distance from the one score line.  By pulling on the finger gripping means, the entire cap member above the third score line is removed in one piece.  The inner closure comprises a plastic member sealed at its periphery to the mouth of the neck and includes a vertically aligned spike-entry port and an additive port which is oriented at an angle away from the entry port.  The spike-entry port in an improved version comprises a spike-retaining collar which is join-ed to the body of the closure by a downward sloping web section which functions so as to cause the collar to grip an inserted spike more firmly to prevent accidental withdrawal of the spike.  An improved version of an inner closure and container neck is also disclosed which includes particulate retaining means to prevent particulates formed during frictional welding of the closure to the neck from entering the container.

Abstract: ABSTRACT OF THE DISCLOSURE        Torque limiting clamping means comprises a cylindrical unthreaded screw-thread engaging clamping member of elastomeric material screwed on a rigid screw threaded member at an interference fit.  The interference fit, the pitch and dimensions of the screw thread, and the physical characteristics of the elastomeric material are preselected to enable deformation of the elastomeric material resiliently within its elastic limit into the thread groove of the rigid member to accommodate the interference fit and to cause screw-induced relative axial movement of the members to a limit of axial travel.  Relative rotation of the two members also produces screw-induced torque forces.  The unthreaded elastomeric member has an abutment means which engages a clamped part.  The resistance forces produced by the clamping in combination with the torque forces provide a limit to the relative axial travel at such limit. The forces achieved between the clamping members and the clamped part at such limit are sufficient to maintain the clamping relationship.

Abstract: ABSTRACT           .         A screwless electrical terminal comprises a connector bar and a clamping cage embracing the bar and biassed by a spring to clamp a conductor between the bar and the cage bottom.   The cage can be latched open for example by teeth on the rear of the cage engaging recesses on the connector bar, to allow insertion of a conductor.    The cage has a forwardly and downwardly projecting pivot element which engages a fixed abutment if traction on the conductor causes the cage to move along the connector bar.   Such movement brings the pivot element into engagement with its abutment and thereafter causes the cage to tilt so as to increase the conductor-clamping force in response to traction on the conductor.
