Abstract: 1,028,041. Deflecting propulsion jets. BERTIN & CIE. Jan. 2, 1963 [Jan. 12, 1962], No. 227/63. Heading B7G. [Also in Division F1] A jet nozzle for a vertical lift aircrait is in the form of an ejector and comprises a series of flattened nozzles 7 through which exhaust gases from a gas turbine engine discharge into a diffuser of rectangular cross-section comprising divergent side walls 12 and parallel end walls 6. The upstream ends of the walls 12 are of rounded form and atmospheric air is drawn into the diffuser by the flow of exhaust gases.

Title: Improvements in or relating to apparatus for filling boxes,trays or the like
IPC: A24C5/354
Filed: 1963-01-02
Abstract: 1,071,741. Packaging cigarettes and like articles. MOLINS ORGANISATION Ltd., and D. W. MOLINS. Jan. 1, 1964 [Jan. 2, 1963], No. 228/63. Heading B8C. An apparatus for filling boxes or trays with cigarettes, multiple filter plugs therefor or like articles comprises a guide, which during filling of a box extends to the bottom thereof, and means for producing relative motion between the guide and the box so that an article-engaging face of the guide and an end wall of the box define an article-receiving space whose length increases during the filling operation. A feeding system F, also duplicated on the left but not shown, is as described in Specification 1,071,742. The articles are conveyed by endless belts 2, 2a to positions above a box 21 which is moved from left to right by pushers 23 on an endless chain 22. The guide comprises an endless belt 27 which is driven in the direction shown and according to the invention pushes the articles already received by the box downwards by frictional engagement to pack them more closely and prevent bunching. In operation the belt 27 is raised to the chain line position on approach of the rear end of box 21, the rate of raising being such that a minimum clearance is maintained between the upper edge of the box and the ascending run of belt 27. The feed of articles from belt 2a is thereby stopped and accumulation of articles on this belt is prevented by the timed operation of a pause device (5) of the lefthand feeding system (F). The feed of articles from belt 2 continues until or just after belt 27 has reached its upper position and is halted by movement of a plate 26 to the left and operation of pause device 5 of the right-hand system F. Counters, e.g. using photo-electric sensing means, may be utilized to control the movements of pause device 5 and other movable parts such as belt 27, plate 26 and belt 22, or an indirect control for parts 22, 26, 27 may be provided via sensing devices at the discharge ends of belts 2, 2a.

Patent GB-921065-A (GB)
Title: Improvements in the colouring of textile fibres of polyalkylenes
Inventor: WARD JAMES STANLEY
IPC: D06P1/92
Filed: 1961-01-05
Abstract: Textile fibres of polyalkylenes, especially polypropylene, are dyed by depositing a dye thereon and then bringing the fibres into contact with the vapour of an organic liquid which is a solvent for the dye and a swelling agent for the fibres, the fibres being at a temperature which is so much below the temperature of the vapour that condensation of the organic liquid on the fibres takes place.  The organic liquids specified are benzene, toluene, xylene, solvent naphtha, chloro or bromo derivatives of methane, ethane, propane, ethylene and propylene such as perchlorethylene, propylene dichloride and especially trichlorethylene.  The dyes specified are substantially water-insoluble being azo dyes and a -arylamino-anthraquinones devoid of carboxylic or sulphonic acid groups.  The dyes may be applied as aqueous dispersions from thickened solutions and the impregnated fibres may then be dried. Advantageously the fibres are exposed to the saturated vapour of trichlorethylene which is produced by boiling the liquid in a container which is open or partly open to the atmosphere, escape of the vapours being substantially prevented due to the high density of the vapour and by cooling the upper surfaces of the container.  An example is given.

In order to reduce the transmission of vibrations up a gear shift lever, the lever is formed with a stem member 12 the lower end of which is accommodated with radial and axial clearance in a socket portion 18 of an actuator member 14. The stem and socket are resiliently interconnected by a ball 20 of polyurethane having a stepped aperture the walls of which are adhesively bonded to the members 12, 14. The ball 20 forms the pivot for the lever and is resiliently held in a socket 40 of a housing 28 by a spring 42. The lower end of the member 14 is formed with a pair of legs 22 straddling a crank pin 32 projecting from an arm 30 fast with a selector rod 26 which is rotated to select conventional striker members and shifted axially to establish a ratio. In order to prevent inadvertent selection of reverse one leg 22 is long enough to limit movement of the shift lever by engagement with the selector rod 26 unless the lever is lifted against the force of spring 42 to raise the leg clear of the rod.
