Abstract: Apparatus for laying lines in an ice rink comprises a frame for carrying a reel of paper to be dispensed onto the ice surface so that the reel runs on an axle carried upon the frame. A spray nozzle is mounted so as to spray water onto the paper after it is laid to form a first layer of ice over the paper. One embodiment provides an arrangement for laying curved lines for forming a full circle and includes a guide pole having a fulcrum pin at one end and a handle attached to the guide pole at the outer radial end for pushing the pole and thus unwinding the paper across the ice around the circle defined by the pole. An embodiment for laying straight lines includes a base frame guidable by a slot which runs across a string laid in the ice. The base frame can receive a full width reel or can be divided into separate portions to receive narrower width reels.

Abstract: A dispenser is used for dispensing plastic film from a roll. The dispenser has a housing that may be mounted under a shelf or cupboard or on a wall. The housing consists of a cover unit that is installed in the place of use and a releasable base unit that fits into the bottom of the cover unit and is held in place with resiliently biased locking tabs. The base unit carries the roll of film, so that the roll is readily installed on the base unit when separated from the cover. The loaded base unit is easily lifted into place. The film is dispensed through a dispensing slot at the back of the base unit. Lengths of film are severed using a cutter at the front of the base unit. The length of film between the dispensing opening and the cutter is prevented from clinging to the underside of the base unit by using a non-planar, roughened surface on the under side of the base plate.

Abstract: A rockbolt monitor monitors increased loadings on a rockbolt in underground mines. The monitor includes a rockbolt plate fitted on the rockbolt to engage the surface of the rock, a stack of belleville washers on the end of the rockbolt outside the rockbolt plate and a spring seat plate outside the belleville washers. When a nut is fitted onto the rockbolt and torqued, the belleville washers will compress to provide the desired force urging the rockbolt plate against the surface of the rock. This spring arrangement allows relative movement of the rockbolt plate on the rockbolt in response to ground movement, such as caused by blasting. The load indicator itself includes a threaded sleeve screwed into a threaded bore in the spring seat plate. A spring loaded piston rides in the sleeve. It is biased into engagement with the rockbolt plate.

An outrigger frame includes a sleeve slideable on the shaft and a plurality of arms extending outwardly from the sleeve each arm carrying a castor wheel to prevent toppling of the device. Steering is achieved by the feet of the user applied to the outrigger frame to rotate the chair and the drivewheel about a vertical axis.

Abstract: A therapeutic pad is formed from a container having elongate compartments arranged in parallel relationship across the width of the container and extending substantially across the full length of the container. The container is formed from a fabric material which is permeable to moisture but contains the filler material which is sand. The compartments are filled with the sand. The use of sand allows moisture to be applied to the container which will then be held within the interstices of the sand for either heating by microwave or cooling by freezing. A separate cover is formed from a quilted padded fabric material shaped to double the size of the container so that it can be folded to cover both sides of the container. One half of the cover includes a moisture impermeable layer to prevent the escape of moisture from that side while the other side allows the escape of moisture. This allows the user choice of applying either moist heat or dry heat to the body of the patient.

Abstract: A cattle gate has a base frame adapted to rest on a ground surface. Upright end frames are secured to the base frame at opposite ends and suspend a grid over the center of the base frame using a spring and chain suspension. The gate is a unitary structure that can be transported either using a truck or by attaching a pair of wheels and a hitch for towing purposes.

Abstract: A trailer for transporting cylindrical bales includes a central frame portion and two side support members. The central frame portion defines two outwardly inclined upper surfaces for receiving the bales extending outwardly from a central apex. The side support members are pivotally mounted adjacent the sides of the central frame and in initial position provide two parallel V-shaped receptacles for two rows of bales. A third row of bales can be mounted on top of the first two rows in the V-shaped area therebetween. The side support members are latched in the transport position and can be released manually so the first one of the side support members pivots downwardly allowing the first and third rows of bales to be discharged. Subsequently the side support members on the other side is released allowing the second row to be discharged. The side support members can be pivoted inwardly to a highway width which automatically resets the latch mechanism.

Abstract: A crop harvesting machine comprises a main frame attached to a hitch of the type which pivots about a centre point of the main frame.

In front of the single draper is positioned a pickup section pivotally mounted relative to the draper frame and controlled in height by guage wheels. The width of the machine is sufficient to pickup two windrows simultaneously at fourteen foot spacings, to deposit the crop from the windrows simultaneously onto the draper and to move the crop to one end of the draper for deposit onto the ground.

Abstract: A transport apparatus of the conventional type which includes a pair of hoppers mounted end to end on a support frame is modified by the provision of discharge augers extending from a position outside the hoppers on the underside of the hopper bottom upwardly and rearwardly therefrom to a discharge spout arrangement beyond a rear end wall of one of the hoppers. One of the augers therefore passes through the second hopper. One of the augers lies directly on the center line while the other is inclined away from the center line of the apparatus so that both discharge spouts of the augers are arranged equidistantly from the rear end wall and spaced slightly side to side.

Abstract: A coin collection device for charity comprises a generally upright body having a transparent front surface through which a track can be observed running from a coin feed slot at the top to a collection box at the bottom. The track divides into two branches at an intersection designed with a ramp so that coins approaching the intersection will normally jump a first branch and enter the other branch. An obstacle causes larger coins to divert into the first branch. Downstream of the intersection both branches are convoluted and intersect at least once for amusement value.

Abstract: The blockage module is designed to be mounted on air seeder seeding equipment. Piezoelectric sensors extending into the flow tubes monitor flow by producing high frequency ringing signals when struck by seeds. During a calibration step, the module will monitor each sensor and adjust the gain of the signal until the number of seed hits per second above a fixed voltage threshold is near a predetermined value. Each sensor connected to the module will be similarly calibrated, and the calibrated gain and hit rate will be stored. It has been found that if a blockage or partial blockage occurs under these calibrated conditions, the number of hits above the fixed voltage threshold will be sharply reduced. The reduced hit rate is compared to the calibrated hit rate, and an alarm is generated if the reduction is great enough. Because the reduced hit rate is immediately detectable, the response time to report a blockage is very short.
