Abstract:
Circuitry is disclosed for sounding an alarm horn when a window or door is opened, and an associated limit switch is closed, the circuitry providing for predetermined time delays suitable for use in either one of two possible modes of operation. A console is provided in the residence to be protected, and contains a battery power source for operating the circuitry, a key control switch, and a mode selector switch. One mode is suitable for use at night when the occupant of the residence is at home, and the circuitry provides for a time delay in sounding the alarm following closing of one of the limit switches, in order to allow the occupant time to close any open exit door or window. The second mode is for use when the occupant leaves his residence unattended, and two time delays are provided for in this second mode prior to sounding any alarm, and after switching the system on. One of these delays is the same as that outlined above, the other delay being of variable duration and in sequence with the first mentioned delay. The occupant has the same nine seconds to re-enter and deactivate the system once he has left his residence, but he also has the benefit of a secondary delay on leaving his residence. Thus, he may activate the system in mode two, open an exit door within a certain time, and procrastinate for any amount of time before leaving and closing the door behind him. Having closed the door behind him he will have the benefit of a short delay on re-entry to allow him to deactivate the system.
Abstract:
A liquid filled transparent container is spun momentarily and successive video frames are then taken by a camera while the liquid swirls in the stationary container. One or more of these video frames can be stored in memory in digitized form. Two or more digitized video frames are then compared electronically, by ''''subtracting'''' one from the other, to generate a reject signal when the ''''difference'''' exceeds some preset number of digitized pulses. The threshold voltage for the video frame being generated can be altered by reference to a stored video frame in order to increase the sensitivity of that frame at discrete points corresponding to voltages exceeding the threshold voltage in the stored frame and desensitized at all other points to reduce the likelihood of spurious signals.
Abstract:
In a bolt action rifle. a guide for reciprocating travel of the bolt having lock lugs fixed to and extending radially from the forward end thereof, and a gas shield or baffle in the form of radially extending lugs pivotally carried by the bolt adjacent the lock lugs. The pivotable gas shield includes a projection which extends outwardly of the shield into slidable engagement in a guideway or recess extending longitudinally in the receiver a distance at least equal to the length of travel of the bolt. Interengaging means between the lock lugs and gas shield limits rotation of the gas shield to a predetermined angle which enables locking and unlocking rotation of the bolt while serving to restrain the bolt against excessive rotation and/or tilting as it is being operated by the bolt handle.
Abstract:
The upstream end of a rectangular glass melting furnace is provided with a doghouse of isosceles trapezoidal shape having three openings through which batch material is introduced in discrete elongated masses, or charges by three batch chargers. Two out of three batch chargers in these openings are operated simultaneously in a predetermined sequence. The two side batch chargers operate along angularly related lines of action which converge with one another at a point also located on the line of action of the center batch charger. During operation of the two angularly related side chargers a composite batch, or mass, is formed so as to travel in a downstream direction in the furnace, and by operation of the center batch charger with one or the other of the two side batch chargers a composite mass or batch is directed angularly outwardly with respect to the downstream direction. Thus, operation of three batch chargers, in pairs, in a sequential fashion, provides a convenient means and method for charging a furnace at a rate double the rate possible with a single charger, or with two chargers operated alternately. Further, the three chargers can be operated in alternate pairs at their respective optimum speeds to provide the desired distribution of batch across the furnace.
Abstract:
A machine is disclosed for loading frangible containers, such as relatively tall glass bottles of the thin walled-non-returnablevariety, into upwardly open packing cases. The bottles are conveyed in discrete side-by-side lanes into a grid structure where they are isolated by conventional brake means associated with each lane. A frame arranged over the grid structure carries a vertically reciprocable carriage having a plurality of individual container gripping units for holding a group of containers while a bottom portion of the grid is opened. Means is provided for retracting the frame and the grid structure slightly, away from those bottles being held by the brake means so that the carriage can be lowered and the bottles passed downwardly through the open grid structure into the case. Each gripper unit comprises a hollow tubular stem portion supported from the carriage, and a lower housing portion which contains a generally U-shaped spring member having depending leg portions with laterally opposed jaws at their respective ends for engaging the neck portion of a container. Each unit also includes a rod slidably mounted in the tubular stem, and connected to the apex of each spring member so that a vertically reciprocable plate in the carriage, to which the upper ends of these rods are connected, can be moved vertically to open and close the jaws on a container.
Abstract:
Optical glassware inspection apparatus with rotating upright ware at an inspection station and fiber-optic bundles employed for light source and/or reflected light pickup devices with light source and pickup centerlines tangential to the ware and perpendicular to each other, the pickup device having a vertically elongated scanning head.
Abstract:
A secondary case magazine is provided above and to one side of an upwardly open primary case magazine from which the lowermost case is cyclically withdrawn for erection. The secondary magazine is disposed generally horizontally, and holds a large number of cases in generally vertical edgewise relation. Escapement means at the exit end of the secondary magazine successively ejects each case for downward movement onto the stack of cases in the primary magazine. Means in the secondary magazine urges all of the cases therein toward said exit end, and said means operates in timed relationship with said escapement means and said means for withdrawing the lowermost case from the primary magazine.

Abstract:
A RECTANGULARLY SHAPED FRAME FOR A PLURALITY OF STRAIGHT LINE SHEARS IS PIVOTALLY MOUNTED ON A PIVOT POST CARRIED ON ONE SIDE OF A GLASS FEEDING APPARATUS SPOUT CASING SO THAT THE FRAME IS MOVABLE FROM AND TO A POSITION BENEATH THE OUTLET SPOUT. THE PIVOT POST IS ROTATABLY SUPPORTED IN A BRACKET WHICH IS ADJUSTABLY MOUNTED ON ARCUATELY SHAPED GIBS DEFINED ON THE SPOUT CASING, AND SAID POST IS VERTICALLY ADJUSTABLE IN THIS BRACKET. THE GIBS ON THE CASING ALSO CARRY A TOGGLE CLAMP, WHICH CLAMP IS ALSO ADJUSTABLY MOUNTED THEREON TO ENGAGE A CLAMP PLATE PROVIDED ON A DIAGONALLY OPPOSITE CORNER OF THE SHEAR FRAME FROM THE CORNER ASSOCIATED WITH THE PIVOT POST.
