Title: Improved means for measuring the altitude of clouds
IPC: G01C3/10
Filed: 1931-06-18
Abstract: 375,986. Searchlights. PINTSCH AKT.- GES., J., 71, Andreasstrasse, Berlin. June 18, 1931, No. 17714. Convention date, July 10, 1930. [Class 75 (iv).] A searchlight, adapted to be arranged at a fixed horizontal distance from an angle-measuring instrument used for determining the altitude of clouds, comprises a casing 1 fitted with a flat hollow reflector 2 of long focal length and an electric lamp bulb 3 having a filament 4 of annular, crossed, or other particular contour so as to project on to the clouds an image of corresponding sharply defined contour.

Abstract: 1302279 Unloading ships; endless conveyers BUEHLER GEBR. AG 14 April 1970 [15 April 1969] 17729/70 Headings B8A and B8E Apparatus for discharging bulk material from ships &c. comprises a pair of endless "en masse" type conveyers 11, 12 pivotally mounted at 13 on a jib 7 of a crane and adapted to discharge the material into a shoot 43 feeding a further endless conveyer 9 arranged on the jib and which in turn discharges the material down a shoot 10 onto a further conveyer (not shown) or a vehicle (not shown). The angle of inclination of the conveyers 11, 12 to the jib 7 is controlled by an hydraulic actuator 33 on either side of the vertical and the angle of the jib is controlled by a pulley block arrangement 8. The conveyers 11, 12, which are reversibly driven by a motor 24, each comprise a series of flights (56), Fig. 8 (not shown), secured to individual links (53) each with a bi-furcated end (54) to receive the opposite end (55) of an adjacent link. A pin (58) hingedly connects adjacent links and the ends (54) have bosses (57) to co-operate with a drive pulley 23. In the embodiment shown the material is conveyed at the lower run of the conveyers 11, 12 and is subsequently discharged directly into the shoot 43. If, however, the material is conveyed on the upper run of the conveyers 11, 12, Fig. 9 (not shown), a pivotal flap (95) is used to direct the discharged material into the shoot and away from the return run of the conveyer.

Title: Improvements relating to exhaust silencers
IPC: F01N1/12
Filed: 1930-06-10
Abstract: 358,970. Exhaust silencers. WILMAN, Z., 6, Rue de Bizerte, Paris. June 10, 1930, No. 17823. Convention date, Nov. 23, 1929. [Class 7 (ii).] The silencer consists of an outer cylinder 1b and a concentric inner cylinder open to atmosphere at both ends, two or more helical baffles between the cylinders forming helical conduits for cooling air and exhaust gas respectively, the exhaust gas conduit being of decreasing cross section in the direction of flow and communicating with the inner cylinder through apertures of progressively increasing cross section. In Fig. 1, two baffles 5, 11 are employed to form conduits for exhaust gas entering at 2, and air entering at 2a, the apertures being shown at 6. A portion of the gases may escape through apertures of increasing size into an auxiliary conduit 1c the outlet from which is controlled by a throttle 1d. Air passes through the inner cylinder due to the motion of the vehicle on which the silencer is mounted. In Fig. 2, four helical baffles are employed of which one pair b, c forms a passage of decreasing area for gases entering at 2, and another pair a, d a passage for gases entering at 2d. Between these pairs of baffles two helical passages are formed for air entering respectively at 2f and 2g. In a modification, the inner cylinder is of divergent form towards the outlet end, and the apertures 6 are formed with lips disposed in the direction of flow. The Specification as open to inspection under Sect. 91 (3) (a) describes also the construction shown in Fig. 1 (Cancelled), in which the exhaust pipe 2 is connected to a casing 1b enclosing a concentric tube 3 the inner end 4 of which is closed and of conical form. A single helical baffle 5 is provided, and the apertures of increasing size are shown at 6. A modified form is also described in which the helical baffle is duplicated in the reverse direction, a concentric apertured wall being located between the casing 1b and the inner cylinder 3. A further modified form is also described in which the silencer is traversed axially by a tube 7, Fig. 3 (Cancelled), one end of which communicates through apertures and a helical baffle 9, with the exhaust pipe 2, and the other end opens into the throat of a bi-conical tube 8 to produce an ejector action. The sound waves are reflected upwardly by surfaces 10. These constructions are not described in the Specification as accepted.

[Class 108 (i).] A transporting device such as a hand-truck or a convever band for use in factories for the conveyance of shoes is provided with a number of upwardly curved supports or arms upon which single shoes can be hung. The hooks or supports may be single or double and comprise essentially a vertical arm 19, Fig. 1, or 24, Fig. 3, the support being secured to longitudinal members 14 of a truck frame 10 having wheels or casters 11. The shoes are hung on the supports in the manner shown. Fig. 6 shows a number of supports secured to frames 50, 51, 52 adapted to be traversed by conveyer chains 53 during the manufacture of the shoes, e.g. in passing through drying means. Fig. 8 shows a method of mounting the supports on cross-bars 38 secured to the pivot pins 40 of a conveyer chain, while Fig. 10 shows a method of securing the supports to the chain links 31 of a chain conveyer by means of brackets 30.
