Abstract: A label applicator is provided for applying pre-printed adhesive-backed labels from a printer to a corresponding commodity in a single stroke. A vacuum-assisted pick-up head receives the preprinted label and in one stroke delivers it and adheres it to a commodity. A new applicator head includes an integrated sponge-like, conformable portion which evenly applies the label, even across the face of an irregularly contoured commodity. The applicator head further includes a slidable pick-up and applicator tube, initially for retaining and then for spot sticking of the label to the commodity. A vacuum is applied to the applicator tube through a pick-up head having a hollow internal portion communicating, regardless of slide position, with the hollow applicator tube and, also, with the applicator head shaft, also having a hollow section for receiving the vacuum source. A downward stroke of the label applicator first causes the applicator tube to spot the label upon the commodity positioned below.

Abstract: This relates to a bonding agent which is used for the production of molded foundry parts and which is composed of two basic components which harden out cold in the mixture of the molded material in the presence of a catalyst under the formation of polyurethane. One basic component is a polyol in the form of a solution of a co-condensate containing an OH group consisting of phenol, aldehyde and an alkyl phenyl siloxane with a contents of at least 3% by weight in free OH groups, if applicable in mixture with a phenol aldehyde condensate containing an OH group, and the second basic component is a polyisocyanate likewise dissolved under normal conditions. Appropriately the solvent has a content in vegetable oils, preferably castor oil.

Abstract: A drafting table having spring-balanced lifting and tilting movement features is provided with an anti-snap device which prevents the table top from tilting so quickly to the full-vertical position that it hits its stops and rocks the entire table over. The anti-snap device comprises a flexible strap which is wrapped about and fixed to cylindric members on which the table top lifts and tilts. The flexible strap becomes tight as the table top reaches its fully vertical position, but tightening of the strap is resisted by the tilt springs, which are pulled to one side by the strap. Resistance to the tightening of the strap requires more force to tilt the top to its full vertical position, increasingly slowing the tilting movement near the end of tilting travel.

Abstract: A trigger circuit is described for use in an MOS clock generator. The clock generator is the type which uses a conventional double bootstrapping circuit coupled to a control transistor to develop a high level clock output signal. The trigger circuit preconditions the control transistor to facilitate proper bootstrapping operation. Included in the trigger circuit is a plurality of interconnected transistors which respond to a pre-charge signal and then a warmup signal for turning the control transistor off and then for establishing selected potentials at the electrodes of the control transistor to precondition it for bootstrapping. In response to a subsequent trigger signal, the trigger circuit enables the control transistor for developing a high level clock output signal.

Abstract: An improved substrate bias generator for MOS integrated circuits is described. The generator includes circuitry for generating two trains of periodic pulses which are approximately phase opposite, one of the pulse trains being slightly delayed as compared to the other pulse train. The two pulse trains are applied to a pumping circuit which generates a target voltage and initially transfers a positive charge into the substrate, and thereafter transfers a positive charge out of the substrate. The positive charge transferred out of the substrate is greater than the positive charge transferred into the substrate when the absolute value of the potential on the substrate is less than the target voltage. Otherwise, a net positive charge is transferred into the substrate. In this manner, the absolute value of the potential on the substrate is driven towards the target voltage.

Abstract: A method is described for fabricating MOS devices of the type found in very large scale integrated circuits. According to the method described herein, various gate oxides and insulating layers are fabricated independently of each other in order to independently tailor their thicknesses and thereby provide improved isolation between gate electrodes and interconnects, and independently controllable operating characteristics for multiple gate electrode structures. The fabrication of a dynamic RAM memory cell, an overlapping gate CCD device and a self-aligned MNOS transistor cell are described using the disclosed method.

Abstract: A synthetic grass hitting surface is slidably positioned within a rectangular frame and is supported by a static surface. The sides of the frame and the static surface form slots. Sideward extensions of the base of the hitting surface are snuggly fitted into the slots. The hitting surface is adapted to slide horizontally on the static surface when a golf ball is struck from the hitting surface, but the snug fit of the side extensions of the hitting surface in the slots and the drag of the hitting surface over the static surface causes resistance to displacement of the hitting surface.

Abstract: A macroboule is disclosed, formed of a bundle of hollow channel elements of fusible material and of different internal diameters. They are arranged with the elements of smallest diameter positioned in the center of the bundle and those of largest internal diameter constituting the outer row of the bundle with uniform or step by step graduation between these extremes. The macroboule is useful for forming a channel multiplier.

Abstract: A fire escape ladder storage and deployment device comprises a series of interfitting cabinet sections adapted to be affixed to an interior surface of an exterior wall adjacent and beneath a window opening through the wall. In its closed position, the device stores a collapsible ladder such as a rope ladder within the compartment, and also provides a table-like working surface. In an emergency, an upper part of the device folds downwardly, away from the wall to reveal the ladder storage compartment and also to form a step above the floor level. An interior member which holds the ladder is then pivoted upwardly and through the window or door opening. The collapsible ladder can be tossed by hand through the open window first, or it can be deployed via the raising and pivoting of the interior member. Raising the interior member exposes a second step, on the wall mounting bracket, and also forms a third step through the window opening. The ladder than hangs to ground level from the interior member.

Abstract: A label applicator is described for seizing a printed, adhesive backed label and for applying the label to a commodity. The applicator includes a pick-up head for vacuum-seizing a portion of the label by its non-adhesive side and for swinging the label to a label transfer station. At the latter station, the pick-up head releases its grip on the label and an applicator head vacuum-seizes another portion of the non-adhesive side of the label and then applies the label to the commodity.

Abstract: A static RAM (random access memory) is described wherein fully asynchronous active equilibration and precharging of the RAM's bit lines provides improved memory access time and lower active power dissipation. In the preferred embodiment, each change in the memory's row address is sensed for developing a clock pulse of a controlled duration. The clock pulse is received by a group of equilibrating transistors and a group of precharging transistors which are coupled to the memory's bit lines. When the clock pulse occurs, all the abovementioned transistors conduct to effect simultaneous equilibration and pre-charging of the bit lines.

Abstract: A folded bit line-shared sense amplifier arrangement is described for sensing the logic state of an accessed memory cell in a dynamic MOS random access memory. In the preferred embodiment, a shared sense amplifier is positioned between and coupled to first and second bit lines via first and second isolation transistors. The same shared sense amplifier is also positioned between and coupled to third and fourth bit lines via third and fourth isolation transistors. When the state of an accessed memory cell is to be sensed, its memory cell capacitor is coupled to a selected bit line and a dummy cell capacitor is coupled to the bit line adjacent the selected bit line. A decoding circuit selectively activates the shared sense amplifier to sense a difference in voltage between the selected bit line and its adjacent bit line so as to determine the logic state associated with the accessed memory cell. Then, the sense amplifier latches into this logic state for reading by the input/output buss lines.

Abstract: An improved method and apparatus for cutting segments from a continuously moving stock piece are disclosed wherein a cut-off press is accelerated to exceed the speed of the stock piece and to substantially eliminate a pushing force by the stock against a positive engagement means. The force of acceleration is reduced and controlled to maintain a minimum bias in the direction of the stock movement by the positive engagement means when the cut-off press attains a velocity equivalent to the moving stock piece. The stock piece is severed into accurate length segments during reciprocal movement cycles of the cut-off press. Back pressure on the stock piece is substantially eliminated by establishing a positive pulling engagement between the cut-off press and the stock piece when moving in the same direction during the reciprocal movement cycles.

Abstract: A hog head is removed by suspending the carcass in a head-down position, marking the skin of the carcass around the neck, engaging a hook in the jaw of the carcass and applying force to the hook to rotate the head upwardly, and disengage the at last joint whereby the head is substantially removed from the carcass. Continuous apparatus includes a head pulling structure running parallel to and synchronized with the carcass suspension system, and preferably horizontally offset therefrom, so that the carcass assumes a "bellydown" attitude when head-pulling force is applied thereto. Semi-continuous apparatus may apply the required force using a flywheel, a crank, a lever or a fluid cylinder.

Abstract: An automatic disconnect circuit is described for disconnecting a remote telephone in resonse to a hang-up click generated when the remote telephone goes on-hook. To distinguish a remote hang-up click from a local hang-up click, voice signals, and the like, all signals on the line are passed through a discriminator for attenuating high frequencies. Signals passing through the discriminator are sensed both as to their amplitude and their duration. Any such signal whose amplitude is too small results in no disconnect. Similarly, any such signal whose duration is atypical of a remote hang-up click results in no disconnect. Only a signal whose amplitude and duration are within predetermined limits, typical of a remote hang-up, causes the remote telephone to be disconnected.
