Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without dis-connecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at least two contact elements close enough to each other to simultaneously contact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resis-tance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: FIRE-RESISTANT MATTRESS AND HIGH STRENGTH FIRE-RETARDANT COMPOSITE              ABSTRACT OF THE INVENTION           An improved mattress includes a composite made of a layer of a fire retardant material capable of providing a heat barrier bonded to a layer of high tensile strength material such as fiberglass fabric. The composite encloses at least most and generally practically all of the flammable ingredients of the mattress.  When exposed to a fire, the fire retardant material chars, thereby creating a heat shield that protects the inside of the mattress while the high tensile strength material holds the mattress together and prevents the mattress from bursting open thereby exposing the flammable ingredients thereof to the fire.          The composite of the present invention is made by bonding a fire-retardant material capable of providing a heat barrier to a high tensile strength material.

Abstract: INCLINED TONER FLOW CONTROL SYSTEM FOR DEVELOPING AN ELECTROSTATIC LATENT IMAGE UPON AN ELECTROPHOTOGRAPHIC FILM            ABSTRACT:   A toner flow control system for liquid toner within camera/processor apparatus includes the disposition of a de-velopment electrode portion (30) and the electrophotographic film (14) within planes inclined with respect to a horizontal plane at an angle of between 30° and 60°. The film (14) and electrode (30) define a toner flow channel (32) therebetween which is also therefore inclined with respect to the horizon-tal plane at the same angle, whereby the flow of the liquid toner (36) through the channel (32) is able to be controlled and uniformly distributed over the electrode (30) and film (14). In addition, gravity discharge (46) of the toner (36) from the channel (32) is able to be accomplished without the need for special sealing devices to confine the toner within the toner cell. The controlled flow of the toner within the channel (32) eliminates the need for substantial negative pressure or vacuum suction systems normally employed in con-junction with vertically oriented toner channels.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention provides a sheet stacker for receiving paper from a printer, copier and the like.  The stacker includes a base, and an elevator mechanism contained in the base.  A hopper sits on the base and includes a floor moveable within the hopper and supported by the elevator mechanism.  As paper enters the hopper a sensor is used in conjunction with activator means to maintain the floor of the hopper at a level to ensure that each sheet slides essentially horizontally onto the stack to avoid curling of the sheet on the stack.  The stacker also includes a paper positioning device above the stacker and operable by the control means to engage selected sheets as they enter the stacker.  This engagement deflects the sheets to one side so that these sheets are staggered with respect to the other sheets in the pile for ease of identification in the finished pile.

Abstract: VEHICLE BRAKE     Abstract A power-operated brake or sprag to prevent a truck or other vehicle from sliding backwards on a slip-pery incline is disclosed.  Prior brakes have not been adequate to prevent heavily loaded trucks from sliding backwards on icy hills.  The present brake features a frame design which allows the ground-engaging legs to be lowered from a point directly behind the rear wheels of the truck.  This configuration causes the added load of the truck to be transmitted through the braking legs to increase their braking effect and offset the tendency of the increased load to slide.  It also allows the use of shorter brake legs so that the legs do not extend beyond the truck chassis when raised.

Abstract: PROTECTION ARRANGEMENT FOR A TELEPHONE SUBSCRIBER    LINE INTERFACE CIRCUIT            Abstract of the Disclosure The contacts of an isolation relay are positioned between a line interface circuit and the associated feed resistors, the relay being controlled to open the contacts in response to an excessive common mode alternating current through the feed resistors.  The common mode a.c. is detected by a sensing amplifier, and is integrated and compared with a threshold level in a detector unit.          If the common mode a.c. is excessive, a zero crossing predictor enables the detector unit to control the isolation relay and open its contacts at a zero crossing of the a.c. A phase shifter in the zero crossing predictor compensates for the response delay of the isolation relay.  As the excessive current is now interrupted, the sensing amplifier responds to the line voltage.  When this falls below a predetermined peak level, a delayed resetting of the protection arrangement is automatically effected.                             - i -

The length of the second beam path is caused to be different from that of the first beam path.  Then the first and second beam paths are combined so that the first and second images may be viewed simultaneously.  The different beam path lengths result in the first and second images being formed at the same position.  As a result, the images carried by the first and second beam paths, both passing through a single objective lens, may be viewed simultaneously at a single location.
