There is described an adjustable dose injection pistol comprising a body assembly (1) including an elongate chamber (8), a piston chamber (3) including a piston (13) slideable in the chamber (8) between filled and discharged positions and means for adjusting (16, 26, 19, 20, 22, 23) one of said positions. The means comprise a selectable plurality of channels (20, 22, 23) included in one of the ass...

A semiconductor device 11 having a moulded plastics body 12 has its stage 13 on which the semiconductor chip 14 is mounted formed separately from the lead frame 21 carrying the leads 15. This enables the innermost part 15a of the leads 15 to overlap the stage 13 and the chip 14. With this arrangement the width of the chip 14 may be close to that of the plastic body 12 without decreasing the resist...

According to the invention, the device consists of a split, threaded container designed for use in outer doors in flats in blocks of flats between the outside and inside of door. Towards the inside, the container is open and equipped with a space for temporary storage of the flat key. Towards the outside, the container can be closed using a lock cylinder that can be locked using a master key. The ...

Stand for sample containers, e.g. test tubes. It is made of elastically deformable material in which there are holes to receive the sample containers. - The body (1) of the holder is made of e.g. foamed plastic e.g. urethane and has holes (2) to receive the tubes. There is a bottom (5) and side walls (9) and (7) of cardboard. The side wall (6) can have an aperture for a hand to be inserted for car...

Stand is made of cardboard and is divided into segments which enable it to be formed into a box that has side walls, a bottom, an upper part and end tabs. At least the upper part has holes for the tubes. When assembled, the stand has a vertical protruding tab which can bear a label.

A combined snowplow and snow scraper for mounting on a wheel loader or tractor comprises a device consisting of two matching scrapers (6, 6') that are articulated with each other and with the help of two hydraulic cylinders (4, 4') (one cylinder per scraper) that are situated on a frame (1) can swing around the joint and form a plow shape. When the two scrapers are completely extended, the device ...

Two spaced parts (1,2), one of which (1) passes on one side of the pylon, are connected to a moving unit. The other part (2) carries the line to be positioned, and passes the pylon on the opposite side. The two parts are joined by at least one component (7) which is rotatable and bridges over the space between them. This component has a recess (9) large enough to allow the pylon cross beam (B) to ...
