Abstract: ABSTRACT OF THE DISCLOSURE     A subscription television system and method in which billing information regarding programs actually viewed by a subscriber of the system is accumulated over non-dedicated telephone lines.  A scrambled television program signal containing a block of television program material, a program identification code unique to the block of program material, and a program category code, is broadcast.  The codes are preferably included in the vertical retrace inter-val of the video portion of the program signal and the trans-mitted program signal is selectively received at a sub-scriber station and selectively unscrambled to permit viewing of the block of program material being transmitted in response to subscriber action indicating acceptance for viewing of the block of program material.  The received program category code is compared with a locally generated category code to determine whether the program is acceptable for viewing.  The program identification code is detected and stored for subse-quent transmission in response to the subscriber action indi-cating acceptance for viewing of the received block of program material.        The program identification code stored at the sub-scriber station is selectively accessed from a remote location over telephone lines on other than a real time basis (e.g., a periodic basis) to thereby provide billing information at the remote location as to programs actually viewed by the subscriber.  The subscriber can thus be billed monthly or on some desired periodic basis for programs actually viewed during the preceding period.  The billing period can be varied from the remote location to provide a means to control the number of programs which a subscriber can receive.

Abstract: THERMAL SWITCH DEVICE WITH SPRING CUP            Abstract of the Disclosure A thermal switch device is constructed with an electrical conductive spring cup contact that fits over a ceramic insulator which surrounds one lead of the device. The center of the spring cup contact has a pattern cut in it so that it is flexible, and a metallic, thin flat disc which is placed against the surface of the spring cup contact which forces the flexible portions of the spring cup contact into contact with the head of the lead that supports the ceramic insulator. A conductive cup-shaped housing that is open at one end encloses the entire structure and is in contact with the spring cup con-tact. The outer ends of the housing being pinched over the ceramic insulator at the open end. A second conductive lead is attached to the outer surface of the conductive housing. A pellet made of a thermally-fusible material is inserted between the housing and the metallic disc so that when it melts the disc moves away from the spring cup contact, thereby breaking the circuit between the spring cup contact and the second lead.

Abstract: INVENTOR:    FRITZ HESS  INVENTION:   APPARATUS FOR SOLDERING COMPONENTS MOUNTED AT              PRINTED WIRING BOARDS     ABSTRACT OF THE DISCLOSURE     A conveyor device containing transport frames, each of which is structured for receiving a printed circuit or wiring board carrying circuit components and guided at their leading and their trailing corners by related guide tracks, leads the trans-port frames to a solder bath, where the transport device lowers the transport frames together with the printed circuit boards to-wards the solder bath and again raises the same therefrom.  During the course of travel of a transport frame containing a printed cir-cuit board carrying one or more of the circuit components through the solder bath one side of the printed circuit board is immersed into the solder bath and then again lifted out of the solder bath.          On the one hand, to prevent that the connection leads or wires protruding from the printed circuit board, during the immersion in-to  the soldering bath, hold back air and, on the other hand, to prevent that during lift-out of the printed circuit board from the¦ solder bath solder bridges will form between the protruding leads or wires, the guide tracks,  viewed in the direction of conveying, possess descending ramps whose spacing from one another is less than the length of a transport frame. Following the descending ramps are ascending ramps, whose spacing from one another approxi-mately corresponds to the length of a transport frame. The equip-ment is particularly suitable for the series or mass production sol-dering of printed circuit boards which carry similar types of circuit components.

Abstract: ABSTRACT OF THE DISCLOSURE          An overrunning clutch including a driving member, a driven member, clutch engagement members rotatably held in apertures formed through one of the driving and driven members and first recesses formed in the other of said driving and driven members wherein the clutch engagement members engage to effect clutch torque transmission, is structured to include a control ring having second recesses formed therein, with the control ring being held by a circumferentially-acting spring in a first position, representing the clutch engaged position, and being movable to a second position representing the clutch disengaged or overrunn-ing position.  The clutch engagement members are held by an axial spring in frictional engagement between the control ring and the other of the driving and driven members containing the first recesses and when the torque transmission through the clutch exceeds a predetermined nominal value, rolling motion of the clutch engagement members operates by frictional contact to cause the control ring to move against the circumferentially-acting spring into its second position whereby the engagement members enter the second recesses and whereby the clutch begins to overrun.

Abstract: Abstract A roof insulating construction comprises a thermal insulating layer above a water impermeable membrane over a horizontal roof deck.  The thermal insulating layer is detached from the membrane and capable of floating on water which collects on the membrane as a result of precipitation or thawing of accumulated ice and snow.  The thermal insulating layer may comprise a plurality of adjacent water impermeable thermal insulating sheets.  The layer of thermal insulating sheets may be fastened to another adjacent layer of thermal insulating sheets in such a way that the layers are mechanically cohesive.  A netting may overlay and may be fastened to a layer of thermal insulating sheets to hold them together. Above the sheets is a protective layer of a weight which prevents the thermal insulating layer or layers from being displaced by wind forces but allows the thermal insulating layer or layers to float on said water.  The protective layer may also be sufficiently opaque to protect the insulating layer or layers from exposure to and consequent degradation by sunlight.

The improve-ments derive from enriching the Li+ -containing solution with a non-competing metal salt (e.g., NaCl) prior to the Li+  removal, thereby achieving higher Li+  loading of the resin composite and obtaining more concentrated eluates.           The non-competing metal salts that can be used are the chlorides, bromides or iodides of the alkali and alkaline earth metals.   28,359-F
