Title: Improvements to sanding disks.
Inventor: OSENBRUGGEN ANTHONY ALFRED VAN
IPC: B24D7/10
Filed: 1998-06-05
Abstract: Accessories for an angle grinder include a disposable rotary sanding disk having quite large shaped ventilating/viewing apertures, for use with a resilient backing plate also having shaped ventilating apertures. The apertures of one or both parts are shaped so that snagging of the apertures on projections from the work surface is minimized and to facilitate air flow across the work surface during use. This air flow helps in cooling the work and ejecting detritus, so minimising clogging effects. The ventilating apertures also facilitate viewing the work to be sanded through the spinning disk during the abrasion process, so that operator feedback is immediate. The holes also give the sanding disk more resilience so that a greater area comes in contact with the work and the disk wears more evenly over its abrasive surface.

Patent NL-7903708-A (NL)
IPC: B01F23/10
Filed: 1979-05-11
Abstract: Gas is mixed into a main flow of gas in a cylindrical conduit by means of one or more feed conduits. In order to achieve good mixing and avoid concentrations of the added gas, the feed conduit(s) have two openings for outflow of the added gas, which openings are spaced from the wall of the cylindrical conduit, are symmetrically located with respect to the axis of the cylindrical conduit and lie in a plane perpendicular to that axis. The axis of these openings are mutually spaced by less than one half of the internal diameter of the conduit. The added gas emerges from the two openings in mutually opposite parallel directions, so that it tends to circulate around the axis. The arrangement has been found advantageous when applied to the feed of gaseous fuel to hot blast stoves of a blast furnace.

Title: Electronic pigeon race recorder - has sealed container for collecting data carrier bearing competition number and upon which time information is recorded
IPC: G07C1/26
Filed: 1982-03-02
Abstract: The electronic pigeon-recorder system cooperates with a data carrier bearing a competition number, pref. in code form, the cooperation being such that the carrier registers electronically on the recorder a time-observation using a built in clock. In its simplest form, the carrier is a magnetically susceptible strip on a ring which is carried on a pigeon's foot. This is stripped off the pigeon's foot and put in the recorder which wipes off any previously recorded data and a time registration is recorded using a writing head. The ring then drops into a collecting tray. When the competition is finished, the recorder is handed in, the race clock is depressed and the seal broken. The collected ring is then read to ascertain the time of clocking-in of the ring. the serving and recording is done visually, optically or electrically.
