Abstract: ABSTRACT:             For the manufacture of magnetic plastics-bonded moulded bodies having different magnetic pro-perties but the same mechanical dimensions, there has so far been proceeded so that the plastics constituent with respect to the magnetic mass constituent is var-ied, which results in a change in the shrinkage behav-for its result that the shaping tools have to be adapted to this varied shrinkage behaviour.  In order to prevent this, according to the invention, magnetic material in having the same shrinkage behaviour, the constituent of plastics remaining the same in both cases.  Since the ratio binder/material to be bonded remains constant as regards volume, moulded bodies having strongly different magnetic properties can be manufactured without having to change the shaping means.

Abstract: ABSTRACT OF THE DISCLOSURE     Electrically-conductive films of tin oxide are prepared by a novel process utilizing gaseous chemical compounds which react to form a tin-fluorine bond at a temperature which is (1) high enough so that the newly-created tin-fluorine bond-bearing mole-cule remains in the vapor phase; and (2) low enough so that oxida-tion of the molecule occurs only after the indicated re-arrangement. Films prepared by the process of the invention are characterized by surface resistances as low as 1 ohm per square when the film thickness is as thin as about a micron.  These films are also characterized by extremely good reflectance of infrared radiation.

Abstract: Abstract A serial impact printer of the type utilizing a dot matrix print head is specifically adaptable for use as a calculator or adding machine and is characterized by utilizing a common drive source to advance the print head across the paper, advance the paper between printing operations, and selectively advance the print ribbon be-tween the ribbon supply spool and takeup spool.  An improved paper-advancing means has been devised which operates in close correlation with the print head drive member to provide a relatively high speed, simplified and inexpensive printer unit; and the ribbon supply spools are so constructed and arranged as to be inter-changeable and to permit direct drive through a spool-engaging member on the print head whereby to advance the ribbon in direct response to print head travel.

Abstract: ELECTRICAL HEATING UNIT WITH FLATTENED EMBEDDED HEATING COIL            ABSTRACT OF THE DISCLOSURE         Resistance heating coils, flattened longitudinally along two sides to have generally oval cross-sections, are totally embedded in situ in a lightweight ceramic fiber insulat-ing body adjacent to and extending along beneath the surface of the insulating body.  Electrical terminal elements extend from the heating coils through the insulating body, and axial move-ment of the leads is prevented by anchoring members welded thereto.  In one embodiment, the coils are embedded in an insulating body having a thickness no greater than about twice the depth of the heating coils.  The resulting compact heating unit is sufficiently thin to be mounted as a retrofit item on the interior walls of an existing furnace.

Abstract: ABSTRACT        The present invention concerns a method of manufacture or valve seats which comprises forming a series of vertically stacked molds each having at least one mold cavity with a configuration approximating that of a ring-shaped valve seat insert blank.  After the molds are formed, they are stacked and the cavities are connected by a common molten metal passageway in such a way that the passageway connects with an axially facing outer surface of each mold cavity to provide a lap gating relationship.  Molten metal is then poured into the lap sated passageway to form a series of valve seat insert blanks each having a gate formed on an axially outer face.  The blanks are then removed from the molds.  Various grinding operations are then applied to the blanks and the axially outer-facing surfaces of the blanks are ground to remove the gates to form valve seats for use in internal combustion engines.

Abstract: DUAL ALARM DETECTION    ON SINGLE LOOP            Abstract A circuit for distinguishing between two classes of alarms on a single loop.  An alarm of a first class causes an impedance of a first predetermined value to be added in the loop; and an alarm of a second class causes a much larger additional impedance, or an open condition, to be inserted in the loop.  The loop is bridged across an element of a voltage divider and, therefore, the loop characteristics, including the changed characteristics due to the impedance change in re-sponse to an alarm of either class, controls the potential of a test point of the voltage divider.  Voltage comparators moni-tor the potential of the test point relative to control poten-tials, and cause relays to provide a no alarm signal, a first alarm signal, or a second alarm signal when there is no alarm condition on the loop, an alarm of the first class, or an alarm of the second class, respectively, on the loop.

Title: Clamp structure, especially axle sleeve clamp
Inventor: OETIKER HANS
IPC: F16L33/025
Filed: 1979-04-25
Granted: 1982-08-03
Abstract: ABSTRACT   A clamp structure consisting of a band for clamping a hose-like member onto a circular support.  The band is capable of contraction by means of an ear from a larger to a smaller diametric dimension without loss of its circular configuration and without any internal projections.  The structure is especially for use with relatively harder and thinner hose-like materials.  The gap in the band under-neath the ear is covered off during contraction to prevent leakage thereat and the open ends of the band can move in side-by-side relationship to one another to change from the larger to the smaller diametric dimension while retaining a complementary configuration to the hose-like member.  The construction thus improves over the art by enabling reduction of the diametric dimension of the band without squeezing out any material of the hose-like object through the gap and without any step-like or other internal projection of the band.

Abstract: III.  ABSTRACT:      There is disclosed massage mechanisms comprising one or more drivers having an angled socket on the end of each driver.  The socket has a massage head rotatably engaged therewith by means of a post fixed essentially perpendicularly to the back of the massage head.  The massage heads are generally conical in shape and can have collars around the periphery and downward from the base.  The socket is angled to a degree which results in the axis of the head and the axis of the driver guide shaft intersecting at a point on the massage head or the driver.  The diameter of the post on the massage head is less than the inside diameter of the socket. In operation the edges of the massage head rise and fall about 26° - 30° in an undulating motion without imparting rotational motion while imparting a kneading, massaging action. The driver rotates at about 60-70 RPM which enables the massaging action to be synchronized to the heartbeat.

Abstract: ABSTRACT OF THE DISCLOSURE     A tennis practicing machine is disclosed which has a rotating arm for periodically projecting a tennis ball towards a player.  A spring connected to the rotating arm stores a rotating force which is periodically released as the rotating arm passes a predetermined point causing ball emission.  A power source control system is provided which controls rotation of the motor such that in order to insure safe operation of the machine, when the machine is turned off a ball is emitted if the rotating arm is within a pre-determined range near the point of ball emission. Accordingly accidental jarring or vibration of the machine does not cause accidental emission of a ball.  Also, the system pro-vides a delay for starting emission of the ball when the machine is first turned on, and furthermore circuitry is provided to maintain a constant time period of operation regardless of power main frequencies of 50 or 60 Hz.
