Abstract: ABSTRACT OF THE DISCLOSURE        A device for cutting a coating which is on a planar surface.  A cylindrical shaft is vertically disposed in two bearings which support the shaft and allow axial rotation.  At the end of the shaft is located a cutting tip which is comprised of a multi-faceted hardened material forming a point. The bearings are supported by a housing attached to a cutter arm used to control the direction of cutting.  As the cutter is moved through the coating, the cutting resistance occurring when a facet of the cutting tip faces the direction of the cut causes the shaft to rotate.  This results in the edge formed by two facets facing the direction of cut so that the cutter can be moved in any direction without orientation.

Abstract: Abstract Locking device for safety belts of the reel-belt type prefer-ably intended for vehicles and provided with a band, which against the bias of a spring can be unwound from a rotating bandreel.  The device comprises a ratchet wheel which normally rotates with the reel and a pawl mechanism with a pawl for cooperation with the ratchet wheel.  The pawl can be switched between a position, in which it re-leases the ratchet wheel, and a locking position, in which it engages the ratchet wheel in order to impede its rotation in one direction. The device further comprises an activating means, which is arranged on one hand to occupy an activated condition and on the other hand to occupy an inactive condition and depending upon its condition to actuate the pawl mechanism for shifting of the pawl between its re-leasing and its locking position.  The activating means comprises a body of inertia, which is adapted under the influence of forces of inertia to be shifted from a rest position to an activated position, and a transmission element, which is designed to sense the position of the body of inertia and in dependence thereof to actuate the pawl. The transmission element and the body of inertia are supported by se-parate supports.  The transmission element is in cooperation with the body of inertia shiftable between an activated position and a rest position under the influence of return forces.

Abstract: ABSTRACT OF THE DISCLOSURE             A method is provided for storing thermal energy in a body which is in direct thermal connection with the surrounding earth.  The energy is transferred to the body from heat-absorbing devices, such as thermal-heat absorbing devices, by circulating a fluid in a circuit incorporating a plurality of chennals and the heat absorbing devices.  Thermal energy stored in the ground-body is removed therefrom by means of the circulating fluid and is used to control the heat of an object, such as a building, by circulat-ing the heated fluid around the object in a further circuit incorp-orating further channels and heat-emitting devices.  The method is characterized in that the channels are arranged in such number and are given such dimensions and distribution in dependence upon the calculated amount of thermal energy supplied and taken out over a long period of time, e.g. one year, that a defining surface sur-rounding said groundbody at a distance   where a     in which  is the frequency for the temperature variation (periodic) cp = the specific heat of the ground-body .lambda. = the thermal conductivity of the ground-body p = density of the ground-body from locations on the remotest of the channels calculated in all directions outwardly from the ground-body, obtains a highest temperature in the order of 35°C and a variation during the time period of at most 10°C dependent on the supply and out take of energy.

Abstract: Abstract A portable apparatus for spraying refractory material on the interior surface of refractory bodies having a fixed top element and a rotating bottom element.  A down-wardly depending adjustable spray nozzle which is angularly positionable to direct refractory material through a 90° arc bounced by a line running through the base of the nozzle perpendicular to the vertical axis of the apparatus and the vertical axis of the apparatus is mounted on the bottom element.  In operation, the apparatus is moved through the length of the vessel while the bottom element is rotated and the angular position of the spray nozzle is adjusted to evenly spray refractory material on the interior surfaces of the vessel.  Through rotation and adjustment, the spray may be downwardly and/or outwardly directed anywhere in a hemi-sphere bounded by a plane running through the base of the nozzle perpendicular to the vertical axis of the apparatus. The spray may also be directed by selective rotation of the bottom element and selective adjustment of the nozzle to concentrate spray at a particular area in the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE         A wheel rim for an agricultural tractor has a central, drum-like cylindrical portion with inwardly projecting circumferential ridges and driver lugs on the ridges to engage clamps on the tractor hub, and outer generally cylindrical or frusto-conical portions, to receive the bead part of the tire, of substantially greater diameter, namely 5-7 inches greater, than the central portion.          Frusto-conical integral intermediate portions join the central portion to the respective outer portions.  The arrangement allows a tractor to take a larger tire size, for increased torque, without the necessity of changing all the wheel clamping arrangements on the tractor hub to accommodate a larger rim.  The design of frusto-conical intermediate portions also enhances the radial strength of the rim.

Abstract: Abstract of the Disclosure A system for infusing fluids into the human body includes a peristaltic-type metering apparatus which con-trols the flow of fluid through a disposable administra-tion set.  The metering apparatus includes a control system which allows the volume and rate of flow of the fluid to be infused to be accurately preset by the operator.  The control system provides an alarm function in the event of malfunction of the pump or occlusion of the tubing of the administration set, and a minimum pumping rate for maintaining fluid flow through a system after the desired volume of fluid has been infused.  Novel power supply circuitry within the control system renders the system immune to power line transients, and a novel bubble detector circuit provides for more reliable detection of air bubbles in the tubing.  A mechanical linkage between the pressure plate and downline flow restriction plunger of the metering apparatus provides for convenient loading of the administration set and for automatic closure of the plunger prior to use.

Abstract: ABSTRACT  OF THE DISCLOSURE            A changeable alphanumexlc sign with printed characters is disclosed.  The sign is universally changeable in the sense that any combination of alphanumeric characters may be displayed by selectively positioning a set of display tapes in each character window.  This arrangement minimizes the length of dis-play tapes required.  Each tape of a set of tapes is printed on both front and back surfaces with character segments and is connected between a driving roller and a driven roller in a manner to display one front surface segment and one back surface segment at a time.  The tape segments which carry the respective character segments are progressively longer from one end of the tape to the other and the set of tape segments which are dis-played together in the window all bear different character segments of the same character so that an entire character is displayed.  All tapes in the set are driven in unison to successively present the character segments of each tape in registry with respective window segments.  An open-loop posi-tioning system is used to position all sets of tapes concurrently but independently to change the characters of the sign.
