Patent GB-797916-A (GB)
IPC: D01H5/56
Filed: 1956-04-27
Abstract: 797,916. Textile drafting mechanism. SKF. KUGELLAGERFABRIKEN GES. April 27, 1956 [April 29, 1955], No. 13042/56. Class 120(2) In textile drafting mechanism comprising a weighting arm which carries the top drafting rolls and is pivotally connected to a fixed part of the drafting mechanism such that it can be raised about its pivot and which can be retained in its operating position by means of a catch mechanism having an operating member, movement of the operating member in relation to the weighting arm results in at least one resilient member of the catch mechanism having load applied to it and the catch mechanism is moved into its locking position or into its release position according to the position of the operating member. In the arrangement shown the weighting arm 4 is held in the operative position by a catch 19 engaging a recess 18a in a catch hook 18. The catch 19 is operated by a lever 20 pivoted at 21 and the lever 20 is acted upon by one or other of the levers 22, 23 mounted on a pin 24 carried by a cover member 14 and both urged against a stop 26 by a spring 25. For disengagement of the catch, the cover 14 is moved rearwardly on the pin 3 which causes the spring 25 to be loaded and the rear edge of the lever 22 to bear against the lever 20 (Fig. 5). The weighting arm 4 is then pressed in a downward direction until the nose 18b of the hook 18 is below the guideway of the catch 19 so that the catch 19 can move out of engagement under the influence of the levers 20, 22 and spring 25, and the arm can then be raised. When the arm 4 and the cover 14 is lowered again the front edge of lever 23 bears against the rear edge of lever 20 in such a way that the lever 23 is pressed rearwardly and the spring 25 is again loaded. At the same time the edge 18c of the hook 18 moves behind the projection 19a of the catch 19, thus preventing displacement of the catch. Slight pressure downwardly on the arm 14 however lowers the nose 18b of the hook 18 thus permitting the catch 19 to slide into engagement under the influence of the levers 20, 23 and spring 25. In a second embodiment the hook member is pivoted from the weighting arm and is acted upon by a leaf spring which can be loaded and unloaded by a cam surface on a pivoted lever. In a third embodiment leaf springs are suspended from a sliding cover member and loaded by a fixed pin and act on a sliding catch similar to that of the first embodiment.

IPC: A23C1/04
Abstract: 134,764. MacLachlan, J. C. April 29, 1919. Rotary apparatus.-Relates to apparatus for obtaining in a granular form the solid constituents of semi-liquid viscous and pasty substances such as the solid constituents of milk. butter-milk, pulped fruit, meat, &c. In preparing in granular form the solid constituents of liquids such as milk, they are first condensed to a pasty condition. The apparatus comprises a highspeed rotary discharge head 49, Fig. 2, and beater 47, the pasty substance being thrown out of the discharge head by centrifugal force against the beater blades, by which it is disintegrated and thrown into a chamber through which a blast of hot air is forced. The material is led to a fixed tube 37, around which a tubular spindle 34 mounted in ball bearings is rotated. The. spindle 34 carries a head 49 provided with eccentric perforations and carrying beater blades 47, which diverge downwardly from the axis of rotation and extend circumferentially on lines eccentrically from the axis and overlap, as shown in Fig. 3, so as to form air passages between the beater blades. In the apparatus shown in Fig. 1, milk is fed by gravity from the tank y to a similar spraying-head into a chamber 7 traversed by a blast of hot air from the pump 16, by which the milk is concentrated. This process is repeated until the milk is obtained in a pasty state. The milk is then pumped to a hopper 11 from which it is fed by a screw 40 to the spray heads, where it is similarly sprayed and disintegrated in the jacketed chamber 19 and dried by means of hot air admitted by ducts 30. The granulated milk is removed by means of screws 23. A duct 51 is provided admitting cold air, by which overheating of the beater is presented.

Title: Improvements in or relating to heat exchangers
IPC: F28D7/10
Filed: 1947-05-22
Abstract: 630,169. Heat-exchangers FRENKEL, M. S. May 22, 1947, Nos. 13842, 17615 and 17616. [Class 64(iii)] A heat-exchanger comprises a row of heat exchange elements surrounded by a guide casing having an entry and an exit for a fluid at opposite ends and entry and exit guide-means in its walls between its ends, for diverting at least a layer of fluid which has flowed in immediate heat exchange proximity with only one heat exchange element away from said element to outside the casing, and for guiding a layer of fluid which has flowed outside the casing and has not yet been in contact with heat exchange elements into direct heat exchange proximity with said element. In one form, Fig. 1, vertical tubes 2, connected to headers 4, 5, are arranged in rows each surrounded by a casing 3 open at each end and provided at each side with slots 6a, 6b. Vanes 7, 8 extend across the casings 3, so that layers of fluid which have been flowing in contact with the outer surfaces of the tubes 2 are diverted away from the tubes, and layers of fluid which have not been in contact with the tubes are diverted into such contact. Opposite ends of alternate passages 12a, 12b between the casings 3 are closed by plates 9, 11. The passages 12b are closed at the sides, and the plates 9, 11 are extended to the walls of the casing 1. Tubes 13 pass through the tubes 2 and headers 4, 5. In a modification, for heating air flowing under natural draught by water-heated tubes, the casing 1, instead of extending down the full length of the tubes 2, extends down only to the extent necessary to enclose passages such as 12b in which the air has already been heated. in a third form, Fig. 6, each row of tubes 2 is replaced by two rows arranged one above the other, each with headers 5, 31 and 37, 33. The tubes of one row are not in alignment with those of the other. When the fluid flowing down through the upper tubes 2 is near the bottom of those tubes, its inner layers are separated from those which have been in contact with the tube walls by tubes 32 leading into the headers 37, and enter into heat exchange in the lower row of tubes 38. The outer layers in the upper tubes 2 flow out through the headers 31. Fluid flowing through tubes 39 passing through the lower tubes 38 is diverted into passages 12b by baffles 40. In a modification of this form, the tubes of the lower row are smaller in diameter than those of the upper row, and are aligned with them and extend through their headers into their lower ends. The inner tubes 39 are dispensed with. The first Provisional Specification describes also a modification of the form of Fig. 6 in which the tubes in the upper rows, like the lower rows, have central air tubes. The third Provisional Specification describes also another modification of the same form, in which the central air tubes are omitted from the tubes in the lower rows, and the upper and lower tubes are connected by short tube lengths to the headers of the lower and upper rows respectively. Specification 626,075 is referred to.

Title: Liquid fuel pumps for internal combustion engines
Inventor: EVANS FRASER MACKIE
IPC: F02M41/14
Filed: 1955-05-13
Abstract: 784,588. Fuel injection pumps. C.A.V., Ltd. April 27, 1956 [May 13, 1955], No. 13853/55. Class 102(1). A fuel pump for internal combustion engines comprises a feed pump of the vane type, a fuel injection pump and a distributer for conveying fuel to each of the engine cylinders. Fuel is fed to the feed pump through a passage d, Fig. 1, the inlet and outlet ports of the pump being connected by a non-return valve e which limits the pressure generated. Fuel from the feed pump is conveyed through a passage m, past an annular groove n to a cavity o which contains a manually operated throttle p. Fuel passes along passage q to each in turn of the radial ports r in the distributer k, driven by a spindle 5 by motion from the engine, and thence along the bore s to the injection pump. During the inward movement of the plungers h, Fig. 2, of the injection pump the fuel is returned along the bore s to the single radial port t which feeds each of the engine cylinders in turn through passages u. Ports 3 in the distributer, similarly situated to radial ports r, convey fuel from the feed pump through a passage 2 to one side of the plunger w, Fig. 2. The pressure on the plunger w causes rotation of the cam j, against the springy, in the opposite direction to the rotation of the distributer k. When the plungers h encounter the cam lobes they impart a return movement to the cam so long as the passage 2 is open via ports 3. When the passage 2 is closed by the distributer the cam is locked hydraulically and the plungers perform their discharge movement. In a modified form to vary the instant at which the injection pump commences its action, Fig. 6 shows a cross-section of pump through ports 3 and channel 2. The ring 6 is angular movable by an arm 7, being operable by convenient means responsive to the engine speed. The fuel passes from the ports 3 to the radial port in the ring 6, through a groove surrounding the ring to the passage 2, to adjust the position of the cam as above. Alternatively instead of the ring 6 the ports 3 may have a chamfer at their trailing edge or the passage 2 a chamfer at its closing edge. In a modified form of Fig. 2 the spring y is on the left-hand side of the plunger and the right-hand side is connected continuously to the outlet side of the feed pump.
