Abstract: TITLE        METHOD AND APPARATUS FOR SUPPORTING A MINE ROOF     ABSTRACT OF THE DISCLOSURE        A reinforcing rod having a threaded end portion with a coupling secured thereto is inserted in a drill hole of a rock formation, such as a mine roof, with the threaded end adjacent the emergent end of the drill hole and the opposite end in contact with cartridges containing a resinous composition positioned within the drill hole.  A bolt having a threaded end portion is engaged to the coupling.  A roof plate is retained on the opposite end of the bolt extending from the drill hole.  A shear pin is positioned transversely in the coupling and maintains the adjacent end portions of the rod and the bolt in spaced relation to permit rotation of the connected rod and bolt in the drill hole to fracture the resin cartridges.  Contact of the threaded end of the bolt with the shear pin maintains the roof plate spaced from the face of the rock formation as the resin is mixed and allowed to cure to adhesively bond the rod to the rock formation.  With the rod anchored to the rock formation further rotation of the bolt advances the bolt through the coupling to shear the pin and urge the roof plate into abutting relation with the rock face. Continued rotation of the bolt tensions the bolt and compresses the rock strata to provide a reinforced rock formation.

Abstract: Wayne M. Wagner 120 Redwood Drive Apple Valley, Minnesota  55124 M&G 758.102/USA                    U-BOLT CLAMP ASSEMBLY Abstract of the Disclosure A saddle for a U-bolt clamp assembly is disclosed.          The saddle is comprised of a single sheet metal member.          The member is folded along a line to form a two-layer web portion and a pair of tubular portions.  Each of the tubular portions receives a leg of a U-shaped bolt.  Each tubular portion is formed of an inner layer of sheet metal which has substantially a 360° circumferential extent and an outer layer bent around the inner layer and which extends around in excess of a 180° circumferential extent.          The outer layer thus serves to hold the saddle in a folded condition without the use of welds.

Title: Zero slip torsional vibration damper
Inventor: BREMER ROBERT C JR
IPC: F16F15/167
Filed: 1979-09-11
Granted: 1981-11-10
Abstract: ABSTRACT           A torsional vibration damper of the type having an inertia ring coupled to a hub by means of an elastomer member. The hub is attached to a shaft subject to torsional vibrations.  The radially outer-most portion of the elastomer carries angularly spaced pockets into which a damping liquid of high viscosity is placed.  The specific improvement resides in thickening the radially innermost portion of the elastomer, relative to the radially outermost portion. In assembling the damper, the radially innermost elas-tomer portions are compressed, while the portions of lesser thickness are not compressed.  A thin film of viscous liquid is adjacent the elastomer portions of lesser thickness, and thus functions as a viscous damper, while the thicker elastomer portions function to elastically dampen torsional vibrations.

Abstract: ABSTRACT OF THE DISCLOSURE           An electronically controlled space heater includes a ceramic block heating element fed by a metering pump with fixed volume charges of liquid fuel at a rate dependent on temperature requirements.  The heating element is located within a combustion chamber.  Exhaust gases vented from the combustion chamber are applied directly to a thermocouple whose voltage output is util-ized to vary or maintain the frequency of a pulse circuit driving the metering pump.  An operator-adjustable potentiometer functions as a thermostat to establish a desired temperature reference value to which the thermocouple output is continuously compared. Start-up and shutdown circuitry precludes the development of unsafe operating conditions.

Abstract: ABSTRACT                           ELECTRICAL BALANCES A balance with electromagnetic load compensation has a coil which is arranged on a balance beam. To improve the temperature-dependent performance of the balance and to reduce the amount of space required, the plane of the coil (54) is normal to the longitudinal axis of the balance beam (36) so that magnetic field lines of a permanent magnet (74) parallel to the longitudinal axis of the balance beam, cooperate with a current flowing through the coil to produce a force on the balance beam compensating for a load applied to the balance.  Such an arrangement is economical to produce and is applicable, in particular, to balances which have a medium degree of resolution in respect of the weighing result.

Abstract: Abstract of the Disclosure A time optimal function generator in a coarse positioning system for magnetic heads in a magnetic disc device is designed to accelerate the magnetic heads as rapidly as possible to the exact point at which they must decelerate as rapidly as possible to stop at the new track location when mov-ing from an old track location.  This device uses as an input the output of a difference register which contains the difference between the present track address and the new track address.  The system is designed to control the servo transducer positioning system in a generally linear fashion as it ap-proaches the new track address but in a square root fashion when the differ-ence is large.  The system contains a square root response portion and a linear response portion with weighting devices to control the proportional response of the system.

Abstract: CARTRIDGE FOR GAS GENERATOR            Abstract of the Disclosure A cartridge for a gas generator of the type in which a liquid such as water is reacted with a solid fuel such as a base metal hydride comprises a canister which contains at least one compressible filler means which cooperates with the canister interior to define a fuel charge compartment. The canister has a plurality of fluid flow passages formed in it to place the fuel charge compartment in fluid flow communication with the exterior of the canister.  Preferably, a pair of compressible filler means such as blocks of a synthetic polymeric foamed material are placed within the canister to define the fuel charge compartment  between them. The fluid flow passages communicate with the fuel compartment so that upon immersion of the cartridge into a liquid the liquid flows through the passages to contact the fuel and react with it to form a gas.  Fuels of this type expand upon such reaction and the compressible filler means are compressed by the expanding fuel to accommodate their increased volume sufficiently to prevent undue compression of the fuel to an extent which would unduly retard the penetration of the liquid into the body of the fuel charge.  The canister is preferably lined with a fluid permeable material such as a fibrous paper to promote even distribution of the liquid about the fuel charge.

Abstract: ABSTRACT OF THE DISCLOSURE         In an exemplary embodiment, after underetching a first poly-silicon layer beneath spaced SiO2 cover layers to produce pairs of confronting SiO2 overhangs with gaps therebetween, and providing an insulating layer at the end faces of the spaced poly-Si-1 electrodes formed from the first polysilicon layer, a second polysilicon layer is produced by chemical vapor deposition (CVD) so as to fill the cavities beneath the SiO2 overhangs via the gaps between each pair of confronting overhangs.  The second polysilicon layer is then etched away so as to leave intervening self-adjusting, nonoverlapping poly-Si-2 electrodes formed from the second polysilicon layer with surfaces terminating for example slightly below the upper surfaces of the SiO2 cover layers.          For a center-to-center spacing of poly-Si-1 electrodes of six microns, the SiO2 overhangs may have an extent (e.g.  .7 microns) about equal to the electrode layer thickness (e.g.  .8 microns).
