Title: Improved means for measuring the amount of work done upon a liquid
IPC: G01L3/24
Filed: 1921-06-29
Abstract: 186,682. Newton, C. F. June 29, 1921. Integrating.-Means for ascertaining the work done upon a liquid by a pumping-plant comprises a differential pressure gauge the movement of which depends upon the effective head imparted to the liquid, and an apparatus which integrates the differential pressure with respect to the quantity of liquid flowing. In the case of water being pumped from a well into a pipe I, one side of a diaphragm in the gauge B is connected by a tube A with a bell D immersed below the level of the water in the well, and the other side is in communication with the water in the pipe by a tube F ending in a Pitot tube within the pipe, facing the pumps, so that the kinetic energy of the water is added to the pressure head. To the diaphragm is fixed a rod C carrying rotatably a roller H actuating a counter J so that the roller is moved to different radii on a disc E rotated by the flow of water in the pipe, as the pressure head varies. The initial position of the roller H upon the rod C is set in accordance with the depth of the bell D, and the reading of the counter gives a measure of the work done upon the water.

Title: Improvements in delivery mechanism for rotary printing machines
IPC: B65H29/60
Filed: 1929-06-11
Abstract: 334,622. Mills, T. J., Chiles, R. W., and Quick, C. G. June 11, 1929. Delivery apparatus.--In delivery apparatus for a printing-machine, a switch device directs the products in batches alternately to delivery flys 14, 15, Fig. 1, rotating in opposite directions, which deposit the products on conveyer-devices 18, 19 respectively moving parallel to one another perpendicular to the axes of the flys. The printed web passes over a former 1 to cutting and folding apparatus 4, 5, 8 of ordinary construction. Pivoted guides 9, 10 actuated through links 23, 24 from a grooved cam 20 direct the folded products in batches of predetermined number alternately to the flys 14, 15. The tapes 18, 19 receive the products from the flys 14, 15 respectively, those on the tapes 18 having their folded edges leading and those on the tapes 19 having their cut edges leading. A kicker device 25 is provided to eject the products from the fly 15 on to the tapes 19 as their direction of movement has to be reversed. The drive for the cam 20 may be changed in order to vary the number of products delivered to each fly. A constantly-driven shaft 26, Fig. 2, having the cam 20 loosely mounted thereon, carries two similar pinions 45, 46 gearing respectively with pinions 37, 38 having slightly different numbers of teeth and loosely mounted on a bush 43 on a lay shaft 29, endwise movement being prevented by a thrust block 44. The shaft 29 is driven either through the gearing 45, 37 or the gearing 46, 38 according to the position of a handoperated sleeve 30 slidable axially thereon and carrying pin-clutch members 34 engaging arcuate recesses 36, 39 in the pinions 37, 38 respectively according to the drive to be employed. The cam 20 is driven from the shaft 29 through gearing 27, 28. If a second former 2, Fig. 1, is arranged alongside the former 1, the delivery arrangements are duplicated, but the tapes 18, 19 corresponding to the former 2 carry the products to the opposite end of the machine. The curved arms of the adjacent flys 15 move within one another in order to economize space.

Abstract: 1284146 Hollow polyamide foamed articles FARBENFABRIKEN BAYER AG 15 April 1970 [19 April 1969] 17947/70 Headings C3C and C3R Hollow articles of polyamide foam are made by foaming a molten anionically polymerizable and foamable mixture comprising one or more lactams, a basic catalyst and an activator, the mixture being fed into a heated mould which is rotatable about two mutually perpendicular axes, the speeds of rotation about the axes being such that the centrifugal force remains smaller than the gravitational force, the mixture being foamed and polymerized at 120-200‹ C. In the examples, mixtures of caprolactam, sodium formate or borohydride as catalyst, and hexamethylene-1,6-diisocyanate or adduct thereof with caprolactam as activator, together with a silicone stabilizer and aluminium powder as nucleating agent were fed into heated rotatory casting moulds (in the form of a truncated cone) which were rotated about two mutually perpendicular axes, to form closed, hollow articles.

Title: Improvements in or relating to the colouring of silver dragees
Inventor: HADLEY JAMES ANTHONY
IPC: A23L1/275
Filed: 1956-06-11
Abstract: Silver dragees are provided with a transparent waterproof coating prior to the application of an aqueous solution of colouring material.  Preferably, the waterproof coating is of shellac.  The aqueous solution of colouring material may contain some sugar and/or gum.  The dragees are coated with shellac by placing them in a container with a small quantity of shellac dissolved in a volatile solvent, e.g. alcohol, and mixing them until all the solution has been used up.  The dragees are then dried on a tray in a current of air.  The coating of an aqueous solution of colouring matter is applied similarly.  A further protective coating, e.g. of shellac mixed with beeswax, is preferably applied on top of the coloured coating.

Title: An improved appliance for transporting logs
IPC: B60P3/41
Filed: 1951-07-30
Abstract: 705,089. Vehicles for handling logs ; lever load-handling machines. LOCKHART; S. F. M. Oct. 2, 1952 [July 30, 1951], No. 17967/51. Classes 78 (3) and 78 (4) A tractor attachment adapted to raise and tow a log, is actuated by the power lift linkage of the tractor. A structure 10 secured to the draft links 7 carries a shovel-like member 24, a roller 27 and a circular track 11 for rollers 15 secured to a rotary annulus 13. The usual upper link is replaced by a lever 17 urged towards the structure 10 by a spring 29 and carrying a cam 28 which, by co-operating with the roller 27 produces an amplified movement of the lever when the arms 7 are raised. Links 19, 20 which are pivoted to the arm 17 for universal movement on a pivot 18, are pivoted at 41, 42 to the upper ends of a pair of grab arms 21, 21 which are pivoted together on a pin passing diametrically through the rotary annulus 13. In operation, with the member 24 located beneath the butt of the log, initial upward movement of the links 7 causes member 24 to raise the butt of the log off the ground with the arms 21, 22 loosely surrounding it, until the amplified movement of lever 17 is sufficient to cause the arms to grip the log whereafter further-upward movement of the links 7 causes the arms to lift the log off the member 24 to a convenient height for towing. The universal pivoting of the arms at 18 and 13 allows the log to swing during cornering. In a modification described in the Provisional Specification only, the member 24 is replaced by spikes which enter the end of the log, and the lever returning spring 29 is replaced by a further roller, secured to the structure 10, which engages the upper surface of the lever 17.

Abstract: 1,211,893. Compressive packaging. H. J. FALBORG. 16 April, 1968, No. 17994/68. Heading B8C. Compressible material, e.g. meat, is compressed by movable walls of a compression chamber, then transferred under pressure to a sleeve, over which a container is placed and filled with the material still under pressure The end plunger-wall can have an outlet 17 for removal of air during compression by a suction pump. The container may be a can which is lined by placing a plastics bag over the sleeve first. The meat 9 is placed in the chamber 1 through its hinged lid 4 and pressure is exerted by plunger-walls (3), Fig. 1 (not shown), 5 and 13. A separating plate 18, with an aperture 20, is moved to permit the meat to enter the sleeve 21 through the aperture, the meat being moved between the plunger-wall 13 and a back-up plunger 22. When the sleeve is full, the plunger 22 is retracted, and a bag and tight-fitting can placed over the sleeve. The plunger 22 then returns to maintain the pressure on the meat and, by unbalancing the force between the plungers 22, 13, allows the plunger 13 to push the meat 9 leftwards out of the sleeve 21. The meat 9 &c. carries the can with it, and as it leaves the sleeve 21, is pushed into the bag and can.
