Abstract: IMPROVED FLUID METERING DEVICE            ABSTRACT OF THE DISCLOSURE          A single facer is provided with an adjustable width glue means including an elongated floating shoe having doctor blade means biased toward a glue appli-cator roll and movable away from the latter to form a metering gap through which glue exits from an elongated fluid cavity of the shoe as a thin film on the applicator roll.  The shoe also includes an elongated fluid manifold which receives glue under pressure from a glue supply.          A plurality of passages formed in the shoe and spaced along the length thereof interconnect the fluid cavity and manifold so that glue flows to the former from the latter. Longitudinally adjustable side dams are provided for the cavity and manifold to control the width of the glue film.  A cleaning fluid introduced at the ends of the manifold flushes through those passages outboard of the dams and exits at the ends of the cavity to prevent build-up of glue in the shoe.

Whiting ABSTRACT OF DISCLOSURE A foundry mould binder component comprising at least one acid selected from the group consisting of glycolic acid, lactic acid,  .alpha.-hydroxy butyric acid, valerolactic acid, .alpha.-hydroxy-caproic acid, tartron-ic acid, tartaric acid, malic acid, mucic acid, citric acid, gluconic acid, and glyceric acid, and a precipitant for the acid,  The precipitant is for admixture with or contains the equivalent to at least 50% of the stoichiometric requirement of the total acid content of the binder com-ponent when the total acid content is in solution, said precipitant com-prising at least one substance selected from the group consisting of cal-clum carbonate and substances composed essentially of calcium carbonate, said precipitant being substantially non-fluxing with the foundry sand, and substantially nonreactive with respect to other mould components than the said acid, and substantially non-reactive with respect to metal which is to be cast in the mould.  Taking one embodiment of the present inven-tion comprising an aqueous solution of 50 w/o citric acid and 3? w/o of a crushed limestone having a 96 w/o calcium carbonate content, and particles in a size range where O w/o is retained on a 140 United States Standard mesh screen and 20 w/o is retained on a 325 United States Standard mesh screen, then any other acid and precipitant mixture are selected to have a precipitation rate no faster than that said embod-iment.  The precipitant is preferably ground limestone, and the binder component may further include at least one humectant (e.g. sorbitol) admixed with the remainder to retard the loss of mould tensile strength during periods of low humidity.

Abstract: ABSTRACT A pacer having an upper and lower rate limit system for preventing pacer malfunction from producing pacer output pulses above or below preset maxi-mum and minimum rates.  The pacer comprises an oscillator for providing clock pulses, a memory for storing parameter data and pacer logic circuitry for produc-ing an input rate signal in response to stored parameter data and clock pulses. Rate limit logic circuitry is responsive to the input rate signal and the clock pulses for producing an output rate signal equal to the input rate signal if the input rate signal is between an upper maximum rate limit and a lower dropout rate limit and for producing an output rate substantially equal to the maximum rate limit if the input rate signal exceeds the maximum rate limit and for producing an output rate at a minimum rate if the input rate is lower than the dropout rate.

Abstract: ABSTRACT OF THE DISCLOSURE            A storage hierarchy has a backing store and a caching buffer store.  During a series of accesses to the hierarchy by a user, writing data to the hierarchy results in data being selectively removed from the buffer store.  Space in said buffer store not being allocated to data being written results in such data being written to the backing store to the exclusion of the buffer  store.  Removal of data increases the probability of writing data to the backing store.  In a preferred implementation, the backing store is one or more disk type data storage apparatus and the buffer store is an electronic random access memory.
