Title: Improvements in propulsive and sustaining propeller apparatus
IPC: B63H5/16
Filed: 1920-03-02
Abstract: 139,785. Oehmichen, E. March 4, 1919, [Convention date]. Screw propellers.-To 'enable the number and width of the blades of a propelling or lifting propeller to be increased by reducing the cavitation effect, a counter propeller with narrow radial arms 2, is carried by a hub which is mounted loosely on the driving shaft of the main propeller 1. The counter propeller automatically rotates in the opposite direction to that of the main propeller and thus tends to neutralize the " following wave" of fluid. The counter propeller may alternatively be mounted on a separate concentric shaft and positively driven in the opposite direction to that of the main propeller. The form of the counter propeller blades is such that the clearance between the two propellers is as small as possible, their inclination may be opposite to that of the main blades, and their pitch may be greater than the pitch of the main blades.

Abstract: 420,639. Machines for extruding viscous fluids. SCHILLING, H., 10, Neumunsterstrasse, Hamburg, Germany. Feb. 27, 1934, No. 6381. [Class 125 (ii)] In a machine for separating and extruding masses of viscous fluid of the kind comprising a pressure cylinder, with a filling device, and an extrusion cylinder at right angles thereto, the pressure cylinder b is provided with a reciprocating piston d which supplies an extrusion cylinder i having a reciprocating piston m which is reduced at one end and opens and closes an opening or openings l between the cylinders band i. The part k of the piston m exercises the function of a pressure piston, after it closes the opening l. The piston d is divided longitudinally and the parts f, d are relatively displaceable for varying the amounts of fluid divided off from the hopper c. The nozzle o may have a series of twisted orifices so that a container fed therefrom, is filled from the wall towards the centre.

Feb. 28, 1935, No. 6425. [Class 100 (i)] In a device for separating sheets from a pile and advancing each sheet beneath a preceding sheet towards a printing-machine, the separating device comprises one or more sets of suction feet 22 operable near the rear edge of the pile to raise the uppermost sheet therefrom, and a sheet-feeding suction foot 2 adapted to take the sheet therefrom to be reciprocated in a borizontal plane above the plane of the pile. The feet 2 may be moved transversely outwards to tauten the sheets, this movement being effected in Fig. 4, by mounting the foot 2 integral with a suction plunger 2a which is drawn into a cylinder 16 when a vacuum is produced in the pipe 3, the extent of movement of the plunger being adjustable. The suction separators 22 are carried by parallel links 26, 28 and are operated from a cam 31 on a shaft 1 by means of a link 30 fitted with a roller 32 in contact with the cam. The extent of movement of the link 28 is controlled by contact of an arm 34 with an adjustable stop 35. The suction feed feet 2 are reciprocated to an adjustable extent by means of a cam 9 on the shaft 1 which engages a roller 8 on a sliding carriage 4 in which the feet 2 are mounted. A spring 10 keeps the roller 8 of the carriage 4, which is fitted with lugs 5, moving on rods 6, in contact with the cam. The movement of the carriage 4 may be limited by an adjustable stop 12 controlling its inward movement. The preliminary separation of the sheets may be assisted by a combing device 37 which is moved to-and-from the pile by cam-and-lever mechanism, and by an air blast device 35. Beneath the combing device the sheets are supported by a blade carried by a oscillating shaft 38 which is moved. into the pile after the same manner as the reciprocating supporting blade described in Specification 343,153.

Abstract: 212,109. Toms, A., (Brill Co., J. G.). March 6, 1923. - Underframing of bodies; springs, arrangement of, and mounting bodies on. - In a bolster member supported at each end on a semi-elliptical spring supported at each end by links or hangers depending from the side member of the truck structure, the links are pivoted to the supporting members at each end so that the spring member swings freely in a lateral or transverse direction, horizontally, without subjecting the connected parts to any twisting strain. The bolster 4, Fig. 1, is supported at each end on a laminated spring 7 which is supported by links 13 from the sideframe 1. The links 13, Fig. 5, are pivoted at 14, 15 to the bracket 16 secured to the side-frame by a bolt 17, the lower ends of the links being pivoted at 11, 12 to a stirrup 8 which houses one end of the semi-elliptical spring 7. When the bolster swings the stirrup rises or falls parallel to the ground and prevents twisting of the semi-elliptical spring.

Abstract: 748,136. Microphones. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 10, 1953 [March 13, 1952], No. 6567/53. Class 40 (4): In a microphone comprising two readily separable sections, the first section, which embodies part of a magnetic system including a permanent magnet, is fixed upon a support, and the second section embodies the remainder of the magnetic system, the arrangement being such that when the two sections are fitted together a magnetic circuit is automatically completed by the juxtaposition of the two sections, a single operation, such as the engagement of a bayonet joint, serving to engage the two sections. The invention enables the defective portion only of a faulty microphone to be replaced, thus obviating the carrying of heavy portions of the magnetic system as spares. As shown in Fig. 2, a permanent magnet 3 is secured to a housing 1, which is in turn secured to a stand 8. Should the microphone become defective, the portion above the line B-B may be removed by turning it about a vertical axis to release the pins 20 (provided on the housing 1) from the bayonet sockets on the removable head, and a spare head is then fitted. The head comprises an iron ring 15 surrounded by an annular layer 16 of plastic material by which it is secured to an external profiled iron ring 17. The latter, which is secured to a cylindrical holder 19, supports the usual diaphragm and moving coil. Connections to the coil are made by plug and socket means of known type (not shown). In another embodiment (Fig. 1, not shown) a cylindrical permanent magnet is mounted on the stand and the remainder of the microphone, which includes the pole pieces, coil and diaphragm, fits over this magnet.
