Abstract: ABSTRACT     A hook flash actuated telephone control device that is connected into a subscriber's telephone line (2 and 2') to permit a user to place an existing call on hold by selectively activating the hook switch (3 and 3') of his telephone (1) according to a particular sequence.          The control device includes a comparator (6) which senses the line voltage and produces an output signal, the level of which is dependent upon whether or not the telephone handset is-in an on-hook or off-hook condition.  A timer (16) and control logic (13) are interconnected so as to be triggered by the output signal of the comparator.  If the telephone handset is in an off-hook condition and the hook switch flash signal sequence is completed within a first particular predetermined time as measured by the timer, a corresponding signal is generated by the control logic to energize a hold circuit (22), whereby to place the telephone circuits in a hold condition.  Audio signal generating means (24 and 26) are also energized in order to provide the user with a tone to indicate that the telephone circuit  are rendered in a hold condition.  Accordingly, the user may return the handset to the telephone cradle without disconnecting the existing caller.  A second timer (20) is interconnected with the control logic (18) to automatically cause the user's telephone circuits to be reset in order to receive new incoming calls, should the user inadvertently place his telephone circuits in a hold condition for longer than a second predetermined time as measured by the second timer.  To resume an existing telephone call, the user merely raises the handset from the cradle of his telephone or any extension thereof, whereby the line voltage changes and the hold circuit is subsequently and automatically de-energized.

Abstract: PREVENTING AIR FILM BETWEEN WEB AND ROLLER         Abstract of the Disclosure A web moving in one direction and having partial wrapping engagement with a cylindrical surface of a rotating roller is impacted by an air jet which forces it into inti-mate contact with the roller, preventing intrusion of an air film between the roller and the portion of the web curved around it.  The jet issues from a nozzle to which pressure air is fed (at, e.g., 3 psi) and the outlet of which is a slot long enough to extend across the full width of the web but as narrow as feasible, e.g., .030 in.  The nozzle is so arranged that the jet impacts the web within a short distance (e.g., 1/2 in.) in the direction of web travel from the line of tangency of the web to the roller, and is close enough to the web (e.g., about 1/8 in.) to avoid substantial dispersion or divergence of the jet before it impacts the web.  Effectiveness of the jet is due to the high pressure gradient in the direction of web travel that it imposes upon the web, not to absolute pressure.

Abstract: FAST-RESPONSE THERMOCOUPLE PROBE AND METHOD FOR MAKING IT                      Abstract Disclosed is a passive, fast-response thermocouple probe for accurately measuring temperatures of fixed or moving areas of surfaces, particularly of lightweight, low-thermal-conductivity materials, with only a minimal modification of their temperatures being caused by the probe's contact therewith.  In making the prober an approximation of the areal heat capacity of the object, the surface temperature of which is to be obtained, is determined.  This information is then utilized to determine the required thickness, density, specific heat, and thermal conductivity of the layer of insulating material which is mounted on the mounting block of the probe.  A thin, low-areal-heat capacity thermocouple is positioned on the upper surface of the insulating layer, and a thin, low-areal-heat capacity cover film is mounted over the foregoing elements and extends partially down the sides of the mounting block. Electrical lead wires attached to the leads on the thermocouple are then connected to a readout device including a reference junction.

Abstract: TIMING CIRCUIT FOR AN OVERCURRENT RELAY            ABSTRACT OF THE DISCLOSURE           A timing circuit for use in an overcurrent relay is disclosed.  A plurality of non-interacting R-C circuits whose outputs are summed is provided.  The signal representing the summed outputs of the R-C cir-cuits represents one term of the inverse time-current relation it is desired to emulate.  Each time the summed signal reaches a predetermined level, a pulse is generated. The frequency of the pulses determines the length of a time delay before the protected circuit is interrupted. When it is necessary to take the second term of the time-current relation into account, this can be done by providing a multivibrator that emits pulses of an adjustable duration responsive to the summed signal and that itself triggers the generation of the pulse train constituting the timing circuit output.
