Title: Photoprinting apparatus for contact-printing sheet originals
IPC: G03B27/24
Filed: 1964-03-26
Abstract: 1,015,609. Photocopying apparatus. CHEMISCHE FABRIEK L. VAN DER GRINTEN N. V. March 26, 1964 [April 10, 1963], No. 12780/64. Heading G2A. Contact-printing apparatus comprises means for separating the original and copy sheets after exposure and conveying them along different paths, and also includes a member mounted in the path taken by the original which is responsive to the presence or absence of an original in said path to control blocking means in the other path to unblock or block that path accordingly. In the form shown, the superimposed original and copy sheets are carried together, by means of a porous belt 4, round an exposure cylinder 1 within which is a light source 2. After exposure, the sheets pass between a suction bbx 8 and a blowing box 9. The air in box 9 blows through a slit in its wall to impinge against a screen 10. This screen forms a narrow aperture at either end with the box 9, thus forming nozzles for jets of air, as shown by the arrows. One of these jets blows the sheets free of the cylinder 1 as they approach it. The upper sheet (copy sheet) is retained against belt 4 by suction from box 8 and is conveyed round roller 5 to pass between guides 11 and 12 to the developing section. The lower sheet (original) is detached from the upper sheet by the suction action of the other jet under screen 10 directed downwards against the wall of box 9. It is gripped by rollers 13, 14, which convey it to a delivery table 15. A plate 18, connected through a lever 19 to the core of an electromagnet 20, lies adjacent the path of the copy sheet, and can be pivoted either into the path of this sheet, so blocking its passage, or out of its path. As the original moves between rollers 13, 14, its leading edge trips the lever of a switch 16, so energizing the electromagnet and pivoting plate 18 out of the path of the copy sheet, and allowing the latter to proceed towards the developing section. If no original is passing between rollers 13, 14 (e.g. if it has remained adhering to the copy sheet and not been separated therefrom) the electromagnet is not energized. Thus the plate 18 remains in its blocking position, and prevents the sheets from being carried round roller 5 to the developing section.

Title: Improvements in roller mills particularly crushing rolls
IPC: B02C4/32
Filed: 1933-05-03
Abstract: 410,967. Roller mills. SOC. ANON. SCHNEIDER, JAQUET, ET CIE, Koenigshoffen, Strasbourg, Bas-Rhin, France. May 3, 1933, No. 12838. Convention date, May 3, 1932. [Class 59.] In a roller mill the bearings of the movable roll are each movable by a bellows, the two bellows being connected by a conduit to another bellows under the control of an adjusting screw whereby the pressure of the movable roll is controlled. As shown in Fig. 1, the movable roller 1 is loaded by spring metal bellows 4, 5 containing gas or liquid and connected by a pipe 7 to a similar bellows 6 which is compressed by a spring 13, the pressure being transmitted to the bellows by a screw 9 carried in a spring follower plate 10. A gauge 8 indicates the pressure on the bearings. In a modification the pipe line 7 is provided with a valve from each side of which pipes lead to separate bellows 6 compressed by a common screwed member through adjustable members whereby the pressure on the ends of the roll may be varied. In Fig. 2 the movable rollers are supported on lever arms 10 suspended by rods 12 from bellows 4, 5, the control bellows 15 being operated by an eccentric 16 carried on one arm of a bell-crank, the other arm 17 of which is supported by a spring 18. The position of the eccentric is regulated by a screw 11. The Specification as open to inspection under Sect. 91 also comprises a movable roller 1, Fig. 4 (Cancelled), mounted on a pivoted lever 23, the free end of the lever being supported on a bellows 28 housed in a casing 26 which is supported by a spring 27 from an eccentric 25. The rod 24 is in two parts connected by a sleeve, and the pressure on the rolls is indicated by a gauge connected to the bellows 28. This subject-matter does not appear in the Specification as accepted.

A floating toy has a propelling motor and connecting means, e.g. a spring steel wire, may be detachably secured to the centre of the toy which may be steered by twisting the connecting means. In Fig. 1 a toy clockwork driven boat is steered by a handle 8, a twistable member 7 and a connecting member 6 which is removable to enable the motor to be wound up. An electrically driven boat Fig. 2 (not shown) may be controlled from a remote device (Fig. 3) having a steering wheel 19 which rotates the connecting means through speed increasing gearing. A switch is provided on the remote device to which is connected a source of current, and one of a pair of current-carrying leads 30, 31 forms the steering connecting means. Current supply may be from an electric battery carried in the boat. Fig. 6 shows a watertight grease box seat 43 for the propeller shaft, and the rudder 35 may be used for stopping the propeller as well as for steering the toy when remote steering is not used. Water-tight fitting of the bottom and top portions 1, 2 of the boat may be obtained by double wall constructions Figs. 7-10 (not shown). Steam and hot air are also specified as propulsion means.

[Class 83 (iv)] Straightening.-Tubes passing over a cooling bed are axially rotated during their longitudinal travel by means of double conical rollers i, whereby the tube is cooled and de-scaled uniformly, as all parts contact at some stage with the rollers, the double conical rollers i being so steeply inclined as to guide the tubes without the assistance of auxiliary side rollers. A tube a, Fig. 2, is lifted from a rolling mill delivery channel c by levers b and rolls down the lifted bars d to a stop e thereon which lowers it on to a weighing machine f from which one set of levers g lift and roll it down to their other end stops h, k or l, thereby distributing the tubes to the various groove channels formed by the series of double conical rollers. At the end of the bed the tubes are stopped at n which brings into operation plungers o to lift them to levers q, r, s which lower simultaneously and distribute them to a reversely running set of double conical rollers u. The bed rollers, extending one and a half to two tube lengths, before and after this transfer, run at higher velocity than the rest of the bed rollers. A straightening device may be inserted where required in the cooling bed, e.g. a series of rollers X and Z above the bed rollers acting to hold down the tube during its travel when being straightened by rollers y. The tubes may be removed from the cooling bed at any desired place.
