Abstract: A game and teaching device construction is described to include a plurality of indicia bearing blocks bound together by a pair of flexible straps. Each block is generally shaped in the form of a solid rectangle whereby a first strap is affixed to each block at one end thereof and a second strap is affixed to each block at the other end thereof. Each block includes front and back faces with one of such faces bearing indicia, for example a plurality of dots, and the other face bearing indicia of the number corresponding to the number of dots on the first described face. When stretched out, the construction is such that pushing the first block will cause the collapse of it and all other blocks in sequence. Furthermore, the construction can be used such that a child is interrogated to associate a number with the number of dots showing on a particular block, with the other face of the block being used to verify the child's answer.

Abstract: The present invention teaches a new antibiotic nanaomycin E represented by the formula: ##STR1## Nanaomycin E is active against Gram-positive bacteria, Trichophyton and Mycoplasma and may be used as antibacterial and therapeutic agents for humans and animals. Nanaomycin E is also a useful starting material for the preparation of nanaomycin A which latter nanaomycin has the highest activity among the various nanaomycin-type compounds. Nanaomycin E is produced by fermentation of a microorganism belonging to the genus Streptomyces and capable of producing nanaomycin E, especially Streptomyces rosa variant notoensis (FERM-P 2209; ATCC 31135) and recovering the same from the fermented liquor.

Abstract: A single lens reflex camera has a built-in winder which includes a reciprocating member reciprocatable in response to forward and reverse rotations of a motor for automatic charge-up of the camera mechanisms as well as for automatic film wind-up.A charge-type drive mechanism has a charge member which is pushed by the reciprocating member upon the forward movement of the latter due to the forward rotation of the motor to move forward for causing the charge-type drive mechanism to store a driving force.The reciprocating member retracts from the charge member upon its return movement so as not to impede return movement of the charge member. An operation mechanism such as a shutter is operated for photographing under the driving force stored in the charge-type drive mechanism, accompanying return movement of the charge member. A film advance mechanism advances a film in response to the return movement of the reciprocating member due to the reverse rotation of the motor.

Abstract: A paper guide mechanism for use with a printer of the type, in which a rolled paper inserted into an inlet opening and introduced by a guide into a printing portion and in which the paper is guided by a guide, after it has been printed, until it is discharged from a discharge opening. A printing device has its printing mechanism assembled into a unit which is accommodated in such a movable block as is rotatable with respect to the body of the printer. Moreover, one of guide plates forming a running path for guiding the paper is fixed to the lower end of the movable block. Thus, the rolled paper being guided through the running path can be easily exposed and accessed by turning or retracting the movable block.

Abstract: An interchangeable lens of the automatic present diaphragm aperture type for a single lens reflex camera includes a swingable actuating lever spring biased to an advanced position and retracted and released by a control member retracted and advanced by the camera mechanism respectively with the termination of the exposure and the initiation of an exposure. A diaphragm blade control ring is spring biased to fully open aperture position and is unidirectionally drive coupled to the actuating lever by a rod projecting from the ring into the path of movement of a projection on the actuating lever so as to follow the lever under the influence of the biasing spring and to disengage the projection upon the diaphragm reaching its fully open position thereby permitting further retraction of the actuating lever and so as to be engaged and positively advanced by the projection with the advance of the lever.

Abstract: A modular display system unit for beverage bottles includes a base assembly and at least two spaced apart upright supporting webs detachably connected to the base assembly. A plurality of shelf assemblies are positioned for support between the webs. Each shelf includes a novel top surface sheet to minimize friction forces between the shelf and the bottles to provide a gravity feed capability when the shelves are tilted forward. Brackets are provided for detachable connection to the webs for adjustably supporting the shelf assemblies between the webs at varying heights and angles of inclination with respect to the longitudinal axis of the webs. The webs include an arrangement of keyhole slots, preferably on both sides thereof, but on at least one side, which serve to support the brackets. The arrangement includes a row of central keyhole slots having their axes aligned with each other and parallel to the longitudinal axis of the web.

Abstract: A wave length filter construction using fiber optics techniques and devices for selective tuning. By core coupling for a portion of the fiber lengths, a communications facility is provided and various wave length selection structures are enabled.

Abstract: A business wallet construction includes first, second and third flaps. The second and third flaps are separated by a fold line while the first flap is attached to the second flap as a hinged, free-turning appendage.

Two removable members are provided for removable diary and note pad use.

Abstract: A residual charge erasing step in the electrophotographic process in which a transparent conductor backed photoconductor layer positioned in virtual contact with a conductor backed dielectric layer is exposed to a light image while a first voltage is applied between the conductors to produce on the dielectric layer an electrostatic latent image, the erasing step which is applied after the transfer of the latent image includes positioning the photoconductor and dielectric layers in virtual contact, illuminating the full surface of the photoconductor layer and applying between the conductors a second voltage of a polarity opposite to the first voltage and whose value is((.chi.a+.chi.d)/.chi.a)(312+6.2 .chi.a)wherein .chi.a and .chi.d are respectively the capacitive air gap equivalent thicknesses in microns between the virtually contacting layers and of the dielectric layer per se.

Abstract: For a photographic lens movable from a first position toward a second position by a shutter release action, the first position is set outside the actual focusing range of the lens from the nearest focused position to the infinity focused position to render the lens pre-movable over a specified distance from the first position to the actual focusing range. Lens position signal generating means operatively related to the movement of the lens generates an electric signal corresponding to the position to which the lens is moved. During the pre-movement of the lens, the position signal generating means emits a signal for initiating a data recording light source into operation so that the light source can be lighted for a substantially prolonged period of time.

Abstract: A single lens reflex camera includes a vertical open topped U-shaped bracket mounted in the camera body below the pentaprism, a forwardly located lens mount separably coupled to an objective lens and pairs of links mutually pivoted between their ends connected between the bracket arms and corresponding edges of the lens mount to support the latter in a fixed orientation for linear longitudinal movement along the camera optical axis. A light tight collapsible conduit extends between the camera body and lens mounts and includes telescoping members with relatively slidable side and bottom walls and an accordian top wall. A rack carrying slide arm projects rearwardly from the lens mount and is engaged by a motor driven gear to longitudinally shift the lens mount. The motor is controlled manually or in response to a focus detecting device and the lens mount may be motor advanced and retracted or motor advanced and spring retracted.
