Abstract: A ground-shaping system attachable to and usable with a back-hoe bucket to shape the upper portions of a ditch to be formed, and to provide flexibility in affording many alternatives. It comprises two, three or more ground-cutting members and clamp means for securing said members relative to the side wall of a back-hoe bucket, there being a back plate for cooperating with the bucket side wall to remove the ground cut by the cutting members.

Abstract: A miniature armature relay having a substantially flat header and a cover therefor. Attached to the header is an electromagnetic operator which comprises an electromagnetic winding and a reciprocatable armature therewithin which carries a disc-shaped contactor.Mounting lugs are fixed to the header on opposite sides of the armature, and individually carry a stationary contact to be engaged by the contactor. Alignment means comprising a pair of anchor lugs on opposite sides of the armature, and a flexible member secured to the armature and such anchor lugs is also included. A biasing spring urges the armature to retracted position and the electromagnetic operator overcomes such spring in response to energization of the winding thereof.

Abstract: A pipe fitting formed of resilient material having two or more end portions disposed at a predetermined angle to each other. A firm metallic sleeve is positioned about the resilient plastic material and a clamp is afforded at each of the end portions. Each such end portion is adapted to receive the end of a threaded or unthreaded pipe and is formed with internal annular ribs for sealingly engaging the pipe. The central portion of the fitting is provided with a thicker wall section so that the internal diameter thereat substantially coincides with or equals the internal diameter of the pipe.

Abstract: A nursing garment wherein the various components or sections are generally rectangular in construction affording a front panel having a pair of rectangular or right angle openings, and sleeve members formed with cover portions which are substantially complementally shaped relative to said right angle openings. Such sleeve members are attached to both a front panel and a rear panel, and removable fastening means in the form of mating velcro parts are used to enable the cover portion of each sleeve member to be removed as desired, from the front panel.

Abstract: A suturing device for sewing animal skin or flesh having a reversely movable arcuate needle and a pivotal rocker arm, said needle and rocker arm being movable in planes at substantially right angles to each other whereby said rocker arm affords a loop in the suturing thread for each succeeding stitch afforded by the needle. When operating, the device includes a continually operating electric motor having clutch means for engaging and disengaging, as desired, a drive shaft and a driven shaft, the latter affording pivotal movement to the needle by means of an extension on the driven shaft which alternately engages drive elements on a pivotal shaft which is attached to the needle. The rocker arm is driven by the driven shaft by engagement of lugs on the driven shaft and a rocker arm shaft parallel thereto.

Abstract: A decorative device for converting street shoes to dress or evening shoes, comprising a mounting tab which fits within the shoe at the rear thereof and from which there is provided depending decorative links of a chain which may be provided with jewels or sequins. A flexible connector is provided at the lower end of the decorative links to encircle the heel of the shoe to thereby anchor the decorative means in place, irrespective of the size of the heel of the shoe. The flexible connector includes metal links which are joined together by springs in the form of a stretch band.

Abstract: An electrically conductive moveable support member for use as a contact carrier, contactor or armature support.Such electrically conductive support member is formed of electrically conductive material of sufficient cross section to carry the desired current, and is formed with reverse convolutions which may be interleaved to provide a small, compact, support member. The convolutions are formed about the mid-point of the length of the material, to leave opposite end portions, one of which may be supported to a base member and the other of which is provided with a contactor, armature or the like.

Abstract: A self telemetering miss-distance radar method and system of high sensitivity and free of second-time-around echoes is provided by phase modulating a continuous wave signal with the output of a repetitive code source such as a pseudo-random noise generator. That signal is transmitted as the radar signal. Returning echoes are applied to one input of a product detector to whose other input a sample of the unmodulated CW signal may be applied. The mixer output contains the product of the CW signal and the echo. The echo includes the CW signal modified to include the noise code and Doppler shift. That product signal is applied to a second product detector to which a delayed version of the noise code is applied. If the code in the echo arrives at the second product detector in unison with the delayed code, the output level will be high. If not, it will be low. The second detector output, the second product signal, is passed through a Doppler filter.

Abstract: A lead-pencil sharpener having a generally horizontally disposed shaving mechanism and a housing thereabout formed with an opening through which a lead-pencil may be inserted into said mechanism. A ledge member formed integrally with such housing or attachable thereto in a generally horizontal position beneath and in close proximity to the opening in the housing to catch lead and wood shavings which fall from the opening in the housing.

Abstract: A safety system for sensing the position of a load being carried by a crane, relative to the boom thereof. It comprises a self-powered radio transmitter positioned on the end of the boom of the crane, and an on-off switch to be engaged by a load-carrying block or hook whenever the load is in close proximity to the boom.The system further comprises a radio receiver within the cab of the crane, such receiver being connected in circuit with suitable warning devices to energize the same upon receipt of a radio signal from the transmitter.

Abstract: A magnetic motor for use as an actuator for devices such as relays, indicators and the like.It comprises an electromagnetic winding having a core member to the opposite ends of which are fastened pole pieces which cooperate with a magnetically movable armature. An additional pole piece as well as a permanent magnet are also provided.One end of the armature is caused to contact or engage one of the pole pieces or, in the alternative, to engage or contact alternatively several different pole pieces. The opposite end of such armature is shaped so as to provide a generally U-shaped air gap with the other pole piece, and the armature is so positioned as to move from one side of coplanar relationship with such other pole piece to the other side thereof.

Abstract: A safety razor wherein the blade-retaining head can be positioned in any one of a plurality of pivotal relative positions between said head and a handle. It comprises a handle which is pivotally connected to a head, the latter of which is adapted to retain a safety razor blade. An arcuately-shaped indexing member having a plurality of angularly-spaced notches is fixed to the head, and spring-biased locking means is positioned on the handle for engagement with the indexing member.

Abstract: A greeting card display comprising an enclosure formed of transparent front and side walls and wherein partition means is provided forming a pair of spaced receptacles.A greeting card having a front cover and a back cover is cut in half, and each of such covers is placed in a separate one of such receptacles. The front cover can be viewed through the transparent front wall of the enclosure and the rear cover can be viewed through the transparent side walls. Means for hanging the enclosure on a wall is also included.
