Abstract: An automobile annual inspection reminder device sets off flashingly a bright light emitting diode (LED) approximately a month before the due date of the next automobile inspection. The device employs conventional battery operated digital watch circuitry to facilitate the setting of a counter/memory to the current time and date and the storage in memory of representations of the inspection due month and day thereof as well as of an earlier alarm date differing by a predetermined interval from the inspection-due date indicated by the facility and storing the same in the memory. A micro switch is provided for each of the twelve months of the year to set the inspection due date in memory. A "Snooze" button provides for temporary inactivation of the LED or beeper. After an inspection, the device can be set to the new inspection-due date.

Abstract: A coin handling protection device is disclosed which prevents thieves from stuffing compressible material through the coin insert slot and into the coin return chute of coin-operated machines. The device prevents stuffing the coin return chute by incorporating a blocking plate across the top opening of the coin return chute such that compressible material stuffed into the coin insert slot is diverted into the open space within the payphone unit. The device is suitable for use in existing coin handling apparatus.

Abstract: A squirrel-resistant bird feeder includes an inner seed-containing cylinder having a central upwardly-extending rod for mounting on a support and side openings for providing bird access to the seed. A hollow cylinder having a top surface with a central opening from about which a central hollow baffle depends controls seed levels while passing seed to lower dispensers. A relatively-movable outer cylinder guards the inner seed-containing cylinder and has side openings which align with the inner cylinder side openings when in its normal or home position to which it is urged by a tension spring. A squirrel alighting on the bird feeder moves the outer cylinder relative to the inner one against the tension of a spring to where their side openings are nonaligned to preclude squirrel access to the inner cylinder seed. A pin and slot arrangement insures opening aligment in the home position. The outer cylinder is formed of gnaw resistant materials.

Abstract: Two embodiments are shown for protecting the pedestal of a public payphone against vandalism. Both employ a stainless steel plate. Both also employ techniques for protecting the stainless steel plate against vandalism. In one, a U-shaped structure and bar is utilized. In the other, internal bars and a cam control are employed.

Abstract: An anti-vandalizing device prevents removal of the coin-return bucket through the coin-retrieval window of the lower-housing cover of a coin-operated telephone while still accommodating coin vault security involving use of one key by the coin collector and of a differently coded key for the upper housing by the maintenance person responsible for fixing the bucket in the lower housing. A guard ring mounted inside an aligned window of a guard wrap reduces the effective size of the guard wrap window to where the bucket cannot be retrieved therethrough even after being crushed against the anti-rocking screw while still accommodating user coin retrieval of his unused deposited coins. The guard ring is slidably mounted on the back side of the guard wrap so as to be retrievable from above in the space between the lower housing cover and the guard wrap when the upper housing is removed. In one embodiment a ridge about the perimeter of an installed guard ring window seats within the guard wrap window.

Abstract: Apparatuses and methods immediately alert a telephone company or other owner/host or operator of a payphone that a vandalizing stuffing has occurred, thereby enabling it or him or her promptly to dispatch a maintenance person to the particular payphone or station to fix it. Stuffing sensing switches are advantageously mounted in a coin return mechanism, and in electromechanical payphones electrically connected to the telephone company central office over one of the existing RING and TIP wires connecting the stuffed or compromised payphone with the central office. Conventional testing techniques periodically employed in the office by the telephone company over the existing wit. installation will then sense whether a payphone has been compromised or stuffed. In electronic payphones, a payphone computer monitors the sensing switches and calls the owner/host or operator to report a problem or gives a local alarm.

Abstract: A Christmas tree stand vertically mounts a cylindrical tube from the bottom of a water container and so that it extends from the top thereof. An inflatable cylindrical bladder is mounted lengthwise to the inside of the tube. The stand is mounted on the trunk of a horizontal tree by inserting its bladder thereon and then inflating the bladder to tightly engage the trunk and center on it. The tree is then uprighted. Leveling screws in the bottom of the stand permit compensating for unlevel room floors and crooked trunks. A container for water about the tube adds ballast and provides life sustaining liquid to the tree trunk through holes in the bottom of the cylinder and in an upwardly concave plate in the bottom of the cylinder supporting the trunk in spaced relation to the container floor.

Abstract: The thermal efficiency of a building is improved by installing a weather block and vent member across the space between the ends of joists resting on a plate having between them an insulation blanket having a vapor barrier adjacent a ceiling on the bottom of the joists. The member blocks the flow of air towards the end of the vapor barrier and the ceiling and sometimes down past the plate in a wall inside covering and down pass the inside covering and the vapor barrier on the blanket insulation between the wall studs, and redirects it upwards along the rafters. It also blocks the flow of air across the plate, to eliminate the Bernoulli Effect thereat which was operative to suck the out the air between the wall-stud insulation vapor barrier and the wall interior covering. The weather block and vent is field adapted to the parameters of the building and is factory scored for easy field adaptation and so that it can be shipped flat for transportation economies.

Abstract: An anti-stuffing device involves removing the floor at the end of the coin return chute to create a floor opening, placing a wall over the end of the chute to stop coins coming down the chute, pivotally mounting at the bottom end of the wall a compound lever so that its one leg closes-off the floor opening when in a first position towards which it is biased, and attaching one end of a compression spring to the other leg of the compound lever and its other end to the bottom of the pivoted door normally closing-off the front opening to the coin return bucket. The spring is of such length that when the bucket door is closing-off the front opening, it yieldably urges the compound lever to its first position closing-off the floor opening and when the lower end of the bucket door is pushed inward it pushes the compound lever so that its one leg moves away from the floor opening and allows the pay telephone user's coins for uncompleted calls to be retrieved by him. Methods defeat old and new stuffing techniques.

Abstract: A lithographic plate scanner provides more accurate representations of the color intensity of the various image areas of a plate having a fixed image by using only a single photocell to read the solid color bar, the white color bar and the successive image areas in a column of the plate. The readings are stored and a computer compares the image area readings with respect to the color bar readings and determines the amount of ink that must be flowed when the plate is mounted in a printing press to replicate the color in the printing, and stores the same on a floppy disk which is mounted in the printing press computer when the printing occurs.

Abstract: The safety guard of a ski lift chair is provided with a rotatable cylinder which bears a ski trail map on its periphery. The cylinder, formed of foam, is slit radially on one side from a central hole rotatably mounting it on the cross-bar of the safety guard having a pull-down position in front of the seated skier. The trail map is on a sheet longer than the periphery of the cylinder and has it ends tucked into the cylinder slit to hold the map sheet in place. The cylinder can be rotated by the gloved skier to view the full length of the trails leading from the top of the particular ski lift. It may also be slid laterally on the cross-bar for viewing by other passengers.

Abstract: Arrangement of fields in binary tree nodes provides a minimal storage encoding storing fixed and variable length keys in factored form in a multilevel tree. A locating method, and apparatus embodying that method, directed by an argument key, which may or may not be stored in the tree, traces a path following arcs upward or downward between nodes in said binary tree, starting from the top node or any other node, until it finds either the argument key or the delta arc where said argument key would be inserted into said tree. The novel binary tree encoding also provides for path tracing starting at a data backpointer field, which allows accessing of neighboring data entries in collating sequence order.

Abstract: A drainage system for a closed-bottom tiltable flower pot employs a reservoir on the bottom of one side of the pot. A straight drain tube extends from the upper inner edge of the reservoir to the upper edge of the other or tilt-down side of the pot. An opening in the bottom of the reservoir only on the one or tilt-up side of the pot admits excess percolation water into the reservoir and allows trapping it on minimal tilting of the reservoir for flow out the drain tube. An air vent tube may be employed to free drainage from the reservoir on tilting. The drain tube may be utilized to water the flower pot by capillary action should surface watering be undesirable. A template or plastic strip may be incorporated for non-flat-bottomed odd-shaped and round-shaped pots, respectively.

Abstract: A telephone is secured against vandalism involving inserting a bare electrically conductive wire through the slot in the MEDECO lock securing the upper housing to the main housing. The free end of the inserted wire is made to contact either the "12" or the "1" terminal on the key pad on the back of the dial housing, to place system ground on the relay controlling the coin switch at the bottom of the chute for inserted coins and neutralize it so that coins can not be released to the coin box if a call is completed nor to the coin return bucket if a call is not completed. An advantageously shaped and located and mounted wire guard prevents the vandalism. The thin guard includes a wire blocking portion, a flange mounting portion, and intermediate portion connecting the blocking and mounting portions, and an inturned portion on its free end for overlying the terminals.

Abstract: A mechanism prevents explosion damage to coin pay telephones by providing an almost horizontal offset in the coin path so that a wad of paper cannot be moved by the weight of subsequently inserted coins. For existing phones, a retrofit provides a horizontal offset by locating a horizontal slot to one side of the existing coin chute entrance and having in back of it a relatively horizontal slippery surface for sliding the coin sideways and then downwards into a tunnel in alignment with the existing coin chute. The tunnel has a sloping bottom surface so that the coin rolls therein under the force of gravity into the existing coin chute. In another embodiment, the horizontal slot is further arranged perpendicular to the existing slot and the relatively horizontal slippery surface slides the coin back towards the horizontal slot and then downwards into the tunnel with a bottom sloping surface operative to roll the coin into the existing coin chute.

Abstract: A new interior wall construction relies on a new metal stud. The new stud is a U-shaped channel having parallel sides and a generally flat bight. The bight is recessed interiorly of its edges and mounts a wood block. The block is secured by diagonally inserted screws piercing the interior corners of the recess. A sheet rock installer mounts the plaster board so as to have common edges with the stud. Thereafter a carpenter inserts a wood blocking in the stud prior to mounting the door jamb.

Abstract: A novel mail carrier sorting case arrangement facilitates the sorting of mail according to current conditions. Compartments formed in a case by vertical dividers are provided for each delivery address. Flags reflecting special current delivery situations with respect to particular addresses are temporarily placed across the entrances to corresponding compartments which must be noted by the sorting mail carrier when inserting the mail. The flags are obstructions which will be noticed physically if not visually, and may be readily deflected. The flags are formed of a strip of flexible material mounted on one end on a spring clip readily attachable to and removable from a divider. A flag has one bending point about which the free end of the strip moves inward facilitating the easy insertion of a single piece of mail into the compartment. The strips may be color coded to indicate broad categories of special situations, and may bear readily mounted and removed information cards which carry detailed instructions.

Abstract: A telephone is secured against vandalism by a double layer face plate or assemblage of tough materials. The assemblage consists of an outer plate covering most of the front of a telephone upper housing or casing, and a second layer covering the housing casing in areas not covered by the outer layer. Two such areas are those which involve openings in the outer or first layer for mounting the standard information pads above and below the dial push buttons. The second layer is open in the area of the push buttons, but the outer layer is provided with a grid thereat for preventing the housing or casing pushbutton grid from being pried out. The outer plate may be provided with wings to also secure the sides and top of the housing or casing against drilling and the insertion of a wire to pin the coin switch vane or to ground the coin switch relay to hold up deposited coins. The outer plate may also be provided with depending portions to cover the telephone coin box and coin return bucket.

Abstract: A coin-operated pay telephone is made secure from the removal of the coin return mechanism by a vandalizing bar and the subsequent collection of returned coins by vandals. A security bar is inserted behind the coin chute and down through an opening in an intermediate strengthening plate to block rocking of the coin return mechanism by a vandalizing bar and its translation forward out of the casing through the opening in which a finger is normally inserted to retrieve coins for incompleted telephone calls. The security bar includes a shoulder which rest on top of the rear edge of the coin return mechanism. The rear of the security bar includes a horizontal slot which is received on the portion of the strengthening plate behind its opening to prevent displacement of the security bar.
