Abstract: 938,559. Rotary exhausters. H. BURGER. Dec. 1, 1961 [Dec. 8, 1960], No. 43001/61. Class 110 (2). A rotary compressor or vacuum pump comprises a rotor 5 mounted eccentrically within a cylindrical casing 4 on a vertical shaft 23 and having a diametral sliding vane 6, circular cover plates 1 and 7, the upper of which consists of a flat plate 1 provided with inlet and outlet openings 2 and 3. Two further casings 10, 11, of similar dimensions are bonded to flanges 12, 13, and form respectively inlet and exhaust compartments 17, 16, and an oil tank in which the rotor casing 4 is submerged for sealing purposes. Oil also partly fills the exhaust compartment 16, submerging the exhaust valve 21.

Title: Improvements relating to air classifiers
IPC: B07B7/08
Filed: 1964-10-23
Abstract: 1, 030, 526. Classifying solids. POLYSIUS G.m.b.H. Oct. 23,1964 [June 11,1964], No. 43241/ 64. Headings B2H and B2P. An air classifier, Fig. 1 (not shown), which is substantially of the type described in Fig. 1 of Specification 934,424, is modified in that the outer conical casing 1a bounding the diffuser 11, Fig. 3, has its edge, adjacent the start of the deflection zone at the outlet end of the diffuser, surrounded by an annular gap 16 for the introduction of secondary air and in that the outer chamber 12 for collecting coarse or heavy material is excluded upwardly beyond the gap 16. The gap 16 is bounded externally by a guide sheet 18 which defines with another guide sheet 19, an annular gap 20 for further supply of secondary air. The sheets 18, 19 form one side of an annular channel 17 which is fed with secondary air. The secondary air serves to reduce the possibility for the coarse or heavy particles of re-entering the main air flow drawn through the inner chamber 13 which collects fine or light material and hence of being entrained into that chamber. The funnel 5 bounding the chamber 13 externally is adjustable lengthwise of the classifier.

Title: Process and Apparatus for Measuring the Distribution of Tensile Stresses Over the Width of Strip Material
Inventor: MUEHLBERG WOLFGANG
IPC: B21B38/02
Filed: 1966-10-18
Abstract: 1,169,381. Measuring strip tension electrically; measuring stress. W. MUHLBERG. Sept.28, 1966 [Oct. 18, 1965], No.43259/66. Headings G1N; G1S and G1W. The variations in longitudinal tension across the width of a strip of material moving over a roller 1, Figs. 3, 3a, are measured by sensing at various regions across the width of the roller, the deflections of the outer shell of the roller 1 towards a fixed axle 3 on which it rotates. The shell rotates on bearings 2, and the deflection transducers each consist of a ring of magnetically permeable material 4 attached to the shell, and two U-shaped magnetically permeable cores 5, 5<SP>1</SP> attached to diametrically opposite portions of the axle 3 so as to form air-gaps between the ring 4 and the poles N1, N2, S1, S1 of the cores. The gaps are differentially varied by deflection of the roller shell 1, and a secondary coil on one pole piece of each core has induced in it, from a primary coil on the other polepiece of the corresponding core, a voltage proportional to the deflection, the two secondaries being appropriately connected in a bridge. Alternatively, the deflection transducers may be strain gauges (7a, 7b, Figs. 5, 5a, not shown) mounted on the inner race 6 of a roller bearing 9 which carries the roller outer shell 1, and which has its inner race 6 fixed to the axle at one portion of its circumference by bolts 8. Deflections of the inner race relative to the fixed portion are produced by stress variations in the strip and are measured by the strain gauges. Alternative devices for measuring deflections of the roller 1 include pneumatic jets with back pressure sensors. The measured distribution of stress may be used to control the thickness settings at various stands of a mill, or to correct roll cambers.

Title: Process for the formation of phosphate glass
IPC: C03B5/08
Filed: 1973-09-14
Abstract: 1421219 Phosphate glass using radio-active waste materials GELSENBERG AG 14 Sept 1973 [14 Sept 1972] 43375/73 Heading C1M A process for the formation of a phosphate glass from a solution of radio-active waste materials comprises introducing the solution, to which phosphate ions and, if necessary, alkali metal ions have been added to adjust the weight ratio of the metal oxide content of the solution to the phosphorus pentoxide content of the solution to that suitable for the formation of phosphate glass, into a zone-heated vessel in a manner such that evaporation of liquid from the solution or slurry, and calcination and melting of the resulting solid material take place exclusively at the wall or the walls of the vessel. If the solution contains nitrates it is preferred to denitrate before use and the solution or slurry may be concentrated before introduction into the vessel, the concentrated material having a solids content of 40-70% by weight. In the specific embodiment (Figure) the solution or slurry is supplied via a feed pipe 2 located at the wall of a cylindrical upright vessel or pipe 1. The feed pipe 2 has an obliquely terminated lower end so that the incoming solution or slurry is guided to the wall of the vessel 1. A thermocouple element guide pipe 3 is arranged coaxially of the pipe 1. The pipe 1 is located in an oven by means of which the lower part (melting zone) has a temperature of 800-1000‹ C., the middle zone (calcination zone) a temperature of 700‹ C., and the upper end (evaporation zone) a temperature of 100‹ C. The upper end of the pipe may originally have a temperature of 200‹ C. which is then lowered to 100‹ C. by the introduction of water via the feed pipe. The monitoring and control of the temperature is effected by thermocouple elements mounted in the guide pipe 3. In a specific embodiment a denitrated waste solution of the following composition is introduced:-F 5À09 g./l., Al 18.35 g./l., fission products 204 g./l., H 3 PO 4  779À6 g,/l. and Na 2 O 65 g./l. The glass melt is discharged from the lower end of the pipe 1 through a discharge pipe 5. Waste vapours produced escape through the waste gas pipe 4.

Abstract: 1,001,977. Fuel injection pumps. ROBERT BOSCH G.m.b.H. Dec. 6, 1961 [Dec. 10, 1960], No. 43665/61. Heading F1A. In a fuel injection pump having a pump piston 10 serving as a distributor which supplies fuel from a single pump chamber to a multicylinder engine, the distributor alternately connects the pump outlet 38 to the pump chamber and the pump inlet 32 to the pump chamber on the delivery and suction strokes respectively and a suction valve 12 is located in the inlet to the pump chamber. A shaft 3 rotates and oscillates the pump piston 10, the bore section 15 of which comprises the pump chamber. A spring 16 keeps the valve 12 closed and fits into the recessed end of a bush 17 which fits closely in the section 15. A flange 18 on the bush 17 abuts a flange of a bush 20 which is slidable axially by the action of a pin 27 mounted eccentrically in a rotating pin 28. A spring 22 is located over a fixed pin 25 and abuts a cap 24 slidable on the pin 25. On the delivery stroke of the piston 10, no fuel will be delivered until the cap 24 abuts the pin 25 because the pressure required to open the injection valve (not shown) is higher than the pressure necessary to displace the bush 17 and cap 24.

A pivotable ventilator window suitable for motor vehicles has a friction brake comprising a friction washer 54 fixed to the pivot shaft 28, a pair of brake members 48, 56 which sandwich the friction washer between them but are prevented from rotating with the shaft, and a leafspring 44 which exerts a pressure against one of the brake members. The ends 46 of the spring are held by a supporting bracket 30 fixed to the window frame (not shown), and the brake members are prevented from rotating by means of a pair of tabs 50 on the member 48, the ends 52 of which engage the opposite edges of the spring, and a tab 58 on the member 56 which fits between the tabs 50. The friction can be adjusted by means of a nut 60 on the shaft, and the angle of rotation of the window is limited by a member 36 non-rotatably fixed on the shaft and having a foot 38 which engages a bump 40 in the bracket 30. The member 36 and friction washer 54 both fit on a non-circular section 34 of the shaft.
