Abstract: PULSATING INFLATABLE-DEFLATABLE PAD ASSEMBLY AND METHOD                         Abstract An apparatus and method are disclosed for promoting the evaporation of perspiration from an absorbent sheet of foam or other material covering an inflatable-deflatable patient-supporting bed pad.  The pad has a multiplicity of perforations in its top wall which communicate with a pair of interlaced passages or chambers within the pad.  By pulsing the air supplied alternately to each chamber of the pad at a frequency within the range of about 15 to 65 pulses per second, the perforations provide a multiplicity of tiny puffing or pulsing jets of air into the foam sheet to promote the evaporation of moisture from that sheet.  Means for overlapping the inflation-deflation cycles is also disclosed.

The apparatus comprises a first U-shaped frame which is adapted to be connected adjacent the rearward end thereof to the tractor rearwardly of the for-ward end thereof.  The forward end of the U-shaped frame is adapted to be secured to the tractor adjacent the forward end thereof.  A second U-shaped frame is pivotally secured adjacent its rearward end to the first frame and has a third frame pivo-tally secured to the forward end thereof.  In one embodiment, a dozer blade is pivotally secured about a horizontal axis to the third frame.

Abstract: Abstract A heat insulating roof structure for an industrial building, in the form of an inter-purlin system com-prising spaced parallel purlins (10, 10A or 35, 35A or 45, 45A) having their base webs (14 or 41 or 50, 51) sheathed by a heat insulating sleeve (16, 17 or 53, 54 or 56, 57), thereby to provide lateral platforms on opposite sides of the purlin for the support of cross members (29 or 70) which form trays to support a layer of heat insulating material (31).  In one form of embodiment the cross members are inverted tee bars (29), thereby forming open rectangularly framed trays for supporting the insulating layer.  In another form of embodiment the cross members are closed tray bases (70) especially suitable for a vapour sealed system.  In all embodiments the insulating sleeve assembly (16, 17 or 53, 54 or 56, 57) serves to minimise or avoid the creation of a cold bridge between the warm building interior and the cold space above the insulating layer (31).

Abstract: ABSTRACT OF THE DISCLOSURE             A counting clock generator for a video tape recorder, in which two different phase counter clock signals at a pulse repetition frequency corresponding to the running speed of a tape are processed to obtain a direction detection signal indicating the direction of running of the tape and a clock signal at a frequency of predetermined times that of the two different phase counter clock signals, and the clock signal thus obtained is counted by a reversible counter, which is controlled for switching between up-counting and down-counting by the direction detection signal with data "O" preset when the tape is running forward and data "maximum value" preset when the tape is running backward, for producing two revised counter clock signals of different phases according to the count output signal from the reversible counter.

Abstract: ENGINE SPEED CONTROL                Abstract of the Disclosure An engine speed control for a variable speed engine wherein the engine can have a set speed to operate at a relatively low working speed or at an idle speed and which is adjustable to increase engine speed.  The engine drives plural pumps and a control circuit is responsive to a certain flow rate from either of said pumps to increase the speed of the engine to provide for additional flow from the pumps.  In a hydrostatic transmission as usable in the drive of a vehicle, there are a pair of fluid translating devices, in the form of a pump and a motor, with at least one of the devices being of variable displacement and having a displacement control responsive to a speed control signal. In such a system, the engine which powers the hydrostatic transmission is set at a desired speed of operation below maximum speed and is adjusted in response to the speed control signal for increase in said engine speed when the speed control signal exceeds a predetermined level.  The control circuit also provides for destroking of the motor at maximum displacement of the pump when both are of variable displacement.

Abstract: A B S T R A C T     Manufacture of a light metal shock absorber by impact extrusion of the light metal of a steel-light metal composite blank, where-by the metallic bonding in this blank was achieved by coextrusion.            The steel component on the bottom face of the light metal shock absorber is provided with a steel ring which was welded or other-wise appropriately joined during or after impact extrusion. Also the light metal sleeve of the shock absorber can - after impact extrusion - be welded or otherwise appropriately joined to light metal.            The manufacture of a light metal shock absorber is a special case of plastic deformation of light metal, and the principles which lead to metallic bonding between light metal and steel or another metal are also valid here.     The composite can be deformed in such a way that the steel comp-onent can be bent without decohesion occurring.
