Abstract: ABSTRACT The interlocking system according to the invention, by the use of multicomputer systems, achieves fail-safety without electromechanical storage-type switching means.  The division of the interlocking territory into smaller geographical control areas is independent of the arrangement of these control areas.  The size of the control areas is limited so that microcomputers can be used in the associated central modules.  The overlap of the control areas insures that a failure of a central module does not result in a restriction of operation.  Any simultaneous failure of several central modules will lead to a restriction of operation only if modules have failed which are assigned to adjacent control areas.  The departure from a purely geographical inter-locking principle permits better storage utilization - the admissibility of control actions is checked, for example, with the air of locking sheets programmed into read-only memories.  The instantaneous state of the route elements is no longer obtained from storage-type switching means contained in the element groups but from the route elements themselves, which provide safe status reports upon request.  Thus the exchange of information between the central modules and their peripherals can take place via a data bus as is suitable for computers, it being possible to sort the information according to its relative importance and to give it priority in the processing sequence if necessary.  In larger interlocking installations, separate communication modules may be provided for managing two separate data buses serving to exchange information with the operating and display facilities or with the control modules for, and the sensors of, the route elements.

Abstract: HAND OPERATED LABEL PRINTING MACHINE            ABSTRACT OF THE DISCLOSURE            A hand operated label printing machine in which a series of labels are incrementally fed onto a printing platen in response to the squeezing of a hand lever so that they may be imprinted with selected indicia.  The hand labeler is equipped with a constant pressure printing mechanism interposed between the hand lever and the frame of the hand labeler.  That mechanism is comprised of a pressure applying assembly in the form of a biased cam pivotally mounted to the hand lever and a pressure receiving assembly also in the form of a biased cam pivotally mounted to the machine frame.  The former assembly is brought into abutment contact with the latter assembly at their cam surfaces, while the hand lever is being squeezed and the cams are then hindered from pivoting following abutment.  The label printing force is the force that has to be applied for the former assembly to ride over the latter assembly which occurs when one of the assemblies resiliently deforms.  The hand labeler also has an ink supply device, comprising a holder that holds two inking rollers.  The ink supply device is movable to bring the inking rollers into and out of contact with the types of the printing device to ink them.  The ink supply device is actuated by a mechanism which is comprised of a combination of a cam pivotally attached to the machine frame and a roller pivotable with the printing head supporting printing lever for being received in the cam and for pivoting the cam with the printing lever.  A link joins the cam with the holder, so that pivoting of the cam moves the holder.  Guide grooves in the machine frame  regulate the inking roller motion along different loci.  The link has a slot in it which prevents the holder from linear protrusion to the front of the labeler frame.

Abstract: MULTIPLE CLIP APPLIER          Abstract An apparatus for housing, feeding and applying multiple ligating clips, including a handle which houses a delivery and feeding mechanism, and a cartridge which holds the clips.  The handle employs a scissors-type action to set a clip which has been delivered to the jaws by the feeding and ratcheting mechanism.  The feeding mechanism provides a relatively long stroke motion to deliver a clip from the end of a cartridge to the end of the nose.  The mechanism also provides a relatively short stroke motion for opera-ting the ratchet mechanism of the cartridge for feeding clips through the cartridge.  The feeding, ratcheting and setting of the clip is all done by a single, scissors-type action employing only a small motion envelope so that the overall shape of the handle may be small and compact and readily adaptable for use deep in an incision site.  The cartridge includes a fixed and moving ratchet rack which are operated by the short stroke ratcheting mechanism of the handle.  Clips are fed from the end of the ratchet into the nose of the handle by a delivery means which may either push the clip into the nose or physically hold and carry the clip into the nose.  The delivery device is driven by the long stroke delivery action of the handle. The entire apparatus may be disposable or the handle may be a reusable item adapted for use with disposable cartridges.

Abstract: ABSTRACT An improved annotatable microfiche film card archival recording system utilizes an intermediate film strip (71) on a movable film head (2) to transfer an image from an initial imaging station (10) to a transfer station (14) where the image on the intermediate film strip (71) is transferred to the microfiche film card (20).  There is provided an optical train including a pair of downwardly facing, inclined and horizontally spaced mirrors (36)  (38) at the imaging station (10), the first of which mirror (36) receives upwardly directed light reflected from hard copy.  This mirror ar-rangement, cooperating with a horizontal film head movement in a direction transverse to the mirror spacing, minimizes the height and width require-ments of the equipment.  A ball joint supported backing means (50) supporting the entire area of the active portion of the film improves image resolution.  Controlled upward displacement of only the image-receiving portion of the inter-mediate film strip (71) during image transfer allows full utilization of the peripheral areas of the microfiche film card (20) when supported on a flange support frame (16).  Controlled downward displacement of the intermediate film strip (71) at the imaging station (10) allows an intermediate film backing element (26) and a microfiche film card image projection illuminator (11) to be acti-vated by a common lifting means (24).  A selec-tively interposable corrector lens (172) optimizes image resolution of this projection.

Abstract: ABSTRACT         There is disclosed an improved collagen sausage casing and a method to produce such a casing.  The normal processes for manufacturing collagen casing are employed. Immediately prior to the point in the process where the collagen extrusion mass is extruded, a proteolytic enzyme is injected into the collagen gel stream.  The proteolytic enzyme is immobilized and becomes non-functioning as the free water required for its activity is restricted by the further steps of the process.  Upon stuffing the casing with a meat emulsion and subjecting the stuffed casing to the smokehouse or cookhouse cycles in the normal sausage manufacturing process or by cooking in the home, the enzyme is again reactivated and continues to breakdown the collagen thereby tenderizing the casing.  The proteolytic enzyme may be papain, bromelain, ficin, fungal protease, bacterial protease, trypsin, chymotrypsin, pepsin and protease.
