Abstract: 844,854. Pipe couplings. HYMATIC ENGINEERING CO. Ltd. Aug. 16, 1957 [Aug. 20, 1956], No. 25339/56. Class 99(1). Coupling parts 1, 2, are locked together by balls 15 engaging an annular groove 5 in the part 1 and an inwardly projecting rib on a sleeve 11 fixed to the part 2. The balls are carried in radial pockets in a cylindrical member 14, the latter having split rings 30 bearing, under the action of a spring 31, against shoulders on the sleeve 11 to hold the sleeve 11 and member 14 in the locked position shown. The sleeve 11 has radial grooves 12, 13 on opposite sides of the projecting rib. To disconnect the coupling the parts 1, 2, are pulled in opposite directions. This compresses the spring 31 so that the balls 15 move into the groove 12 and are freed from the groove 5. In the form shown the parts 1, 2 are adapted for attachment to the hose of an airman's suit and an air supply hose respectively. With the parts detached a spring pressed valve 20 closes the bore of the part 1. In the assembled position a member 32 in the part 2 engages the valve and holds it open.

Title: Improvements in or relating to outboard propeller mechanisms
Inventor: DEWHURST PETER KITSON
IPC: B63H20/10
Filed: 1954-09-01
Abstract: 773,610. Outboard propellers. WHITEHEAD ENGINEERING (WILLESDEN), Ltd., J. Aug. 29, 1955 [Sept. 1, 1954], No. 25445/54. Class 114. In an outboard propeller mechanism in which a shaft extends downwardly through a housing and drivingly engages a propeller shaft at the bottom of the housing, the housing being mounted for rotation about an axis usually above and parallel to the surface of the water, when the mechanism is mounted on a barge &c., to permit the housing to be raised and lowered by a mechanism provided for that purpose, means for securing the housing in a predetermined angular position about the axis consists of friction means arranged to oppose rotation of the housing thereabout. A propeller housing 2 pivots from its operational to its idle position about an horizontal axis 4 transverse to the length of the barge carrying it. The barge is fitted with a pair of upstanding cast iron lugs 11 each having a circular aperture 13 to house a pair of end covers 12. On their inner faces these covers are channelled at 14 to receive distance pieces 16 which, with the covers 12 are drilled to receive bolts 18 adapted to draw the covers together when nuts 19 are tightened thereon. Recesses in the inner faces of the distance pieces 16 accommodate projections 22 on a cast iron friction block 21 which divides into two parts the space enclosed by the covers 12 and distance pieces 16. Each space thus provided houses a rectangular section bronze bar 7 and the two bars extend beyond the covers to be pivoted at 9 to a lug 8 on the housing 2. The bolts 18 and nuts 19 are tightened to produce sufficient frictional resistance to prevent the housing turning about the axis 4 (and so moving the bars 7 through the covers 12) under maximum power of the propeller 5. In a modification the bolts 18 pass through an additional outer plate adapted to be urged away from the adjacent cover 12 by a central screw abutting thereagainst to close up the covers 12.

Patent GB-482285-A (GB)
Title: Improvements in or relating to processes and apparatus for filling containers with liquids
IPC: B08B9/20
Filed: 1936-09-23
Abstract: 482,285. Bottling liquids &c. HOLSTEIN & KAPPERT MASCHINENFABRIK PHONIX GES., and FEHRMANN, K. Sept. 23, 1936, No. 25842. [Class 125 (ii)] When filling bottles &c. with liquids such as beer, the bottles &c. are first scavenged with inert gas such as carbon dioxide, supplied from a measuring vessel such as a cylinder and piston 4, 8, Fig. 1, the gas so measured being delivered as through a pipe 13 to a point close to the bottom of the bottle. As an alternative, the measuring vessel may be arranged on the discharge side of the bottle, the necessary measurement being the volume of air displaced from the bottle. In the first modification, movement of the piston is effected by eccentrics or cams, or in the case of rotary bottling machines, by a groove 11 in which runs a roller 10 carried by the piston rod 9, the supply of gas to and from the cylinder being controlled by a plug cock 3 ; to enable the machine to be used with large or small bottles, the stroke of the piston can be varied by building up the groove of parts of appropriate curvature or by constructing the groove of parts pivoted together so that the inclination of the groove may be adjusted. The rate of delivery of gas to the bottle is arranged so as to prevent eddying therein; on the other hand, the cylinder 4 may be filled at a more rapid rate than its discharge ; by arranging that before the end of the discharge stroke of the piston the bottle is withdrawn, the entry of air through the open mouth of the bottle is prevented. During the operation of filling with liquid the bottle scavenged with inert gas, precautions have also to be taken to prevent the entry of air. For this purpose, the multiple-way cock 25, Fig. 4, of the filling head is provided with an additional passage 30 and communicating therewith an additional groove 26, the former at the moment the filled bottle is to be withdrawn being put in communication with a source 32 of inert gas, and the groove with the passages 27, 28, 29 of the filling head, so that no air can enter these parts and so lead to the contamination of the contents of the bottle next to be filled.
