Abstract: 676,194. Machine tool details. VICTORIA MACHINE TOOL CO., Ltd., FRYE, J., and SELBY, J. Nov. 17, 1947 [Oct. 17, 1946], No. 30933/46. Class 83 (iii). [Also in Groups XXIV and XXXVII] The calculator 5 described in Specification 647,708, [Group XIX], is applied to the speed control of a variable gear or an electric motor driving a machine tool so that the action of manually setting the two graduated dials 2, 3, representing respectively variables such as linear cutting-speed and diameter of rotating work or cutter, automatically sets the gear for the selection of the correct spindle-speed appropriate to the said variables. The mechanical change-speed control is the preselector of Specification 587,604, [Group XXIV], wherein a disc 12 is preselectively rotated and moved bodily axially by an executive control (not shown here), to turn pinions operating gearstrikers, and meshing racks, 'the positions of which are determined by holes of varying depth and position on the preselector disc 12. During the executive axial movement, rotation of the preselector disc 12 is prevented by a pin 11 which enters one of a series of holes 10, defining gear positions, the pin being pointed and the holes flared to cause the disc to align itself with the nearest ratio-position during the initial movement. The driven plate 1 of the calculator of Specification 647,708, [Group XIX], is directly connected to rotate the preselector disc 12, so that the action of setting the graduated dials 2, 3 automatically sets the disc in position for the nearest desired ratio to be introduced by the executive control. The speed-control of an electric motor in equivalent manner is described with reference to Fig. 3 (see Group XXXVII).

[Also in Division B8] A product is enclosed in a web of supercooled polyvinylidene chloride film, or between two such webs, making use of the property of such films of adhering together on contact and without heating. The apparatus described is generally similar to that in Specification 965,032, but the side dies of that Specification are omitted, vacuum being introduced to draw the film together through passages 42, 44, 55 in the upper and lower dies 32, 28. The films may have an admixture of'polyvinyl chloride or of plasticizers such as ethyl phthalyl ethyl glycolate and tertiary butyl salicylate. The Specification gives suitable times and temperatures for treatment of the webs in water baths to produce partial crystallization, so that the seals between the webs, though hermetic, can be pulled apart. This tempering may be effected in parts only of the webs. The whole of the webs is heated subsequently to complete crystallization ; this may be effected, while the webs are still within the forming dies, by radiant heaters which heat the dies. Each packet may be sub-divided so that its compartments may be opened one at a time to provide access to single articles. A printed and folded card may be included in each package. Each web may be a laminate of two films, one of which provides mechanical strength while the other provides oxygen impermeability, and one or more layers of each laminate may be of a material other than polyvinylidene chloride. Specification 965,034 also is referred to.

Title: Improvements in and relating to internal combustion engines
IPC: F02B75/02
Filed: 1922-11-16
Abstract: 212,607. Kingcome, H. A. Nov. 16, 1922. Valves; valve gear; regulating.-In engines in which scavenging and charging is effected by cooled compressed air admitted into the cylinder before the end of the exhaust stroke, during the suction stroke, and for a portion of the compression stroke, the point at which compression starts in the working cyinder is controlled automatically by means dependent on the delivery pressure of the compressor and controlling the inlet valve of the cylinder. As applied to a compound engine with two power cylinders 1, 2, Fig. 1, the double-acting air pump 38 delivers to a cooler 39, from which the air passes to an admission port and chamber 6, 7, Fig. 2. The entry of the cooled compressed air from the chamber 7 to the cylinder is controlled by a ring valve 10 worked by oil under pressure through rams 11. The oil is supplied by a pump 49, Fig. 5, delivering to an accumulator 50, the supply to the rams being controlled by a valve 52 moved by a cam 54. The cam is slidable axially on its shaft to vary the working of the valve 54, and therefore the time of closing of the valve 10; the axial movement is effected by a piston 56 subjected on one side to the delivery pressure of the pump, and on the other side to the pressure in the receiver between the high and low pressure cylinders. The point at which compression commences in the cylinder is controlled by the balance between these two pressures. The exhaust from the high-pressure cylinder and the admission and exhaust of the low-pressure cylinder are controlled by two similarly-actuated ring valves 16, 27. The pressure of the air &c. tends to hold the valves closed. In a modification, the time of opening of the admission valve is controlled by the cam 54, Fig. 7, which is adjustable from a centrifugal governor 63. The governor is connected through links 64, 66, 67 to a floating lever 73. which is connected at its other end through links 83, 78 to the rod of a piston working in the cylinder 79. The lever 73 controls the valve 77, which admits pressure fluid to one side of the cylinder 79; the other side of the cylinder is connected to some other pressure source. On a variation in speed, the governor moves the valve 77, which causes a movement of the piston in the cylinder 79, this movement returning the valve to its neutral position and adjusting the cam 54. The weight 70 opposes the governor movement on increase of speed.
