Abstract: ABSTRACT OF THE DISCLOSURE       A valve operating device for the intake or exhaust valves of an internal combustion engine wherein a plurality of cam followers are disposed adjacent to each other for operation by different cams in mutually different modes dependent on the speed of rotation of a camshaft. A selective coupling mechanism disposed in and between the cam followers has switching pins movable between a connecting position in which the cam followers are interconnected and a disconnecting position in which the cam followers are disconnected. An oil passage is provided in one or more of the cam followers and the switching pin therein is arranged to control the rate of flow of oil through the oil passage defined in that cam follower in response to movement of the switching pin between the connecting and disconnecting position. The oil supplied through the oil passage is used foe lubricating the cam and cam following sliding surfaces in one embodiment and for operating hydraulic valve lash adjusters in another embodiment.

Abstract: ABSTRACT      An implant comprises  interconnected compartments  with inlet and outlet  and can  be used for  sampling of  entered serous fluid  or  to  hold drug  concentrate  for  selective delivery,  if  desired.   The  compartments  are  formed  by sealing around porous foam rings between a top and a  bottom layer of biocompatible elastic membrane with a polymer paste which sets to form a rubbery shell.  The top membrane  layer over  the  compartment  is punctured  to  create  a   small resealable channel.  Upon subcutaneous implantation,  serous fluid under  hydrostatic pressure  seeps into  the  interior through the  puncture orifice.   The  entered fluid  may  be withdrawn by an hypodermic syringe through the rubbery  side wall to obtain serum-borne  bioactive materials.  If a  drug concentrate is  included, the  entered fluid  will  dissolve some of  the  drug  therein.   When  delivery  is  required, external sidewise  compression  of the  elastic  compartment over the  skin  fold  expels the  drug  containing  solution therein through the orifice.

Abstract: IMPROVED REBAR CUTTING AND BENDING MACHINE                 ABSTRACT OF THE DISCLOSURE A hand-operated rebar cutting apparatus in-cluding first and second discs carried by a shaft mounted on a frame.  The discs are pivotable relative to each other and each includes grooves which can be aligned for receipt of a bar to be cut.  The first disc is piv-otal on a shaft carried by a frame and moves incremen-tally through a predetermined arc such that the grooves become substantially axially offset from each other. The apparatus is attached to a manually operable bender and straightener having a linearly reciprocable slide mounted within a guideway.  As the slide is reciprocated, the first and second discs of the apparatus are pivoted relative to each other.  The apparatus includes a ratchet mechanism for allowing incremental pivoting of the discs relative to each other through the predetermined arc, while allowing reciprocable movement of the slide to its initial position without returning the first and second disc to the position in which the grooves are aligned.  The apparatus also includes return means for pivotally returning the first disc in a second direction through the entire predetermined arc during a single return stroke of the slide.  When the grooves are sub-stantially axially offset from each other, a bar placed in the aligned groove is thereby cut.

IPC: F16J15/32
Filed: 1988-12-20
Granted: 1994-08-09
Abstract: A modified internal seal for a universal joint is provided. The seal is for a universal joint of the type comprising a cross having trunnions with annular shoulders therearound and with a bearing cup for each of the trunnions with the bearing cup having an interior shoulder adjacent the open end thereof. The seal is substantially recessed within the bearing cup at the open end. The seal comprises a sealing member having a lip which engages a portion of the trunnion at the shoulder thereof and an oppositely extending lip which engages the shoulder of the bearing cup. The sealing member has additional lips extending inwardly and outwardly for engaging the trunnion and the bearing cup. The sealing member has a deep annular groove between the lip which engages the shoulder portion of the trunnion and the outwardly-extending lips, the groove opening outwardly away from the bearing cup. The latter lips can have discontinuities in the form of slits or notches extending generally radially from outer extremities toward base portions thereof. The groove is located closer to the outer lips than the inner lips to form the sealing member into a thick, sealing body and a much thinner, lubricant-escape flap.

Abstract: ABSTRACT         The knife sharpeners that are on the market do not work satisfactorily.  The new knife sharpener is distinguished by a good sharpening effect and high reliability in operation.  A grinding device (2), which consists of a carrier unit (3) with two resiliently designed supporting arms (6, 7) for two grinding disks (8, 9), is positioned in the plastic housing (1) of the knife sharpener.  When assembled, the grinding disks (8, 9) extend in sections and at a mutual distance through slits (17, 18) in the housing wall (16) into a trough-like recess (19) in the hous-ing (1) which is accessible from above.  Through partial over-lapping (20) of their peripheries (21, 22) in the area of the recess (19) the two grinding disks (8, 9) form a sharpening angle (.alpha.) that is continuously adjustable within a range of 40° to 50°.          The knife sharpener is preferably suitable for household requirements.

Abstract: Climbing forms for stepwise erection of concrete walls have a platform which is supported by a frame having elongated carriers extending at right angles to the outer side of the wall to be erected and being removably suspended on anchors which are embedded in the wall. The platform supports a pair of parallel guide rails for a form member which carries the boarding of the climbing forms. The rails guide the carriages of the form member so that the boarding can be moved between an advanced position in which it is adjacent to the cavity into which concrete is to be poured and a retracted position in which the wall and the boarding define a passageway which is accessible to workmen on the platform so that the workmen can clean and/or otherwise treat that side of the boarding which faces the wall. The guide rails are mounted in such a way that the platform need not be provided with uncovered slots, gaps, cutouts or other types of openings which would endanger the occupants of the platform or would permit objects to drop from the platform and thus endanger the persons or equipment below the climbing forms.

Abstract: In an inverter controlled with a firing unit connected to switches and defining an operating frequency, a resonant frequency of a series oscillating circuit of the inverter connected to one of the switches is placed below this operating frequency. Given this operating situation, a short of the d.c. voltage source is impossible. Given, for example, unfavorable component tolerances, however, the operating frequency can be moved close to the resonant frequency and cause impermissibly high voltages at the components. Such a voltage rise is limited according to the invention by means of a voltage-dependent resistor. It preferably lies in series with a capacitor and takes care of a voltage-dependent shift of the resonant frequency.
