Filed: 1939-03-09
Abstract: 526,148. Picketing machines; capsules; collapsable tubes and containers. STEVENS, A. H. (Stokes & Smith Co.). March 9, 1939, No. 7647. [Classes 66 and 94 (i)] [Also in Group V] Containers or capsule: filled with liquid are made by applying heat and pressure to form flattened sealed sections along a tube of thermo-plastic web material impervious to liquid, intermittently feeding the web by pulling each section in turn, introducing the liquid into the tube in the interval between the formation of successive sections, and severing the sealed sections. Nested tubes or webs may be used to obtain multi-ply sealed sections. The web W is drawn from roller R over the forming tube 1 and sealed longitudinally at S by heat and pressure as described in Specification 440,328. The end of the tube so formed is sealed by heated clamping means 2, the slide 3 in the reservoir 4 is moved over the open end of the tube 1 so as to discharge the predetermined amount of liquid, the heated clamping means 2 are moved from the full-line position to the dotted-line position to form a seal closing the bottom of the next container, the clamping means is moved back to the full-line position thereby drawing down the web, and the filled capsule is severed by the cutter 6. The process is repeated to form successive filled capsules. A similar process is used to form multi-ply capsules from nested tubes (Fig. 4, not shown). The longitudinal seam S may take different forms (Figs. 2, 3, 5, not shown). Single-ply capsules may be formed from two webs (Figs. 6 to 8, not shown) and multi-ply capsules from four webs (Figs. 9 to 11, not shown). Completed packages in the form of closed bags of rectangular section may be similarly formed (Figs. 12, 13, not shown). The web may be paper, cloth, metal foil &c. impregnated or coated with thermo-plastic material.

Classes 68(1) and 85 [Also in Group XXX] In a tool for sinking wells comprising blade 2 pivoted to the tool body 1, and a control member 12 axially displaceable relative to the body for opening and closing the blades, the member is connected to a rotatable rod 16 by a connection preventing relative rotation, the rod extends. for sliding and rotational movement. through the wall 17 of the body and the member and the body are connectible by lugs 26 capable of being displaced into axial slots in members 27 to permit the body and blades to be rotated by the rod. The blades are described in Specification 834,931, each blade being connected by a link 5 to a fitting 8 rotatably mounted on the member. The member is fixed to a plate 14 carrying the lugs and to a sleeve 15 fixed to the rod which is rotated by a table 29 and passes through a bush 28 in the wall 17. Downward movement of the member and the plate is limited by a partition 13 in the body, the member and the plate being raised from the partition by the tensioning of a cable 23. The cable is anchored at 24 on the wall and passes in succession around pulleys 18 ... 22 before passing through the rod, the pulleys 19, 21 being mounted on the wall and the pulleys 18, 20, 22 being mounted on the plate. After a sinking operation when the space between the blades is filled with earth, the cable is tensioned to close the blades, the lugs moving to the position A (Fig. 3). Further tensioning of the cable hoists the tool from the well so that the tool may be suspended by hooks 37. The cable is then released to open the blades (position 2b, Fig. 1) to discharge the earth, the lugs moving to the position B. After discharge the rod is turned slightly and the cable tensioned so that the lugs take up position D and the blades are slightly opened to permit lowering into the well. After the tool has been lowered it is rotated for the sinking operation, during the initial rotation the lugs move to the position E and the blades take up their cutting position 2a.

Abstract: 990,597. Colour television receivers. COMPAGNIE FRANCAISE DE TELEVISION. Feb. 27, 1963 [March 2, 1962], No. 7951/63. Heading H4F. In a receiver for use in the SECAM colour television system where the sub-carrier is modulated alternately a line rate by two colour signals A and B, the channel supplied by the sub-carrier comprises a direct channel 11<SP>1</SP> and an indirect channel 11<SP>11</SP> having a one-line duration delay, the outputs of the two channels being connected to an adder circuit 12 and to a subtracter circuit 13 which is followed by a polarity inverter 14 and a switch 15 which is changed over at line rate by a control signal applied at 17. The output at 18 thus comprises A+B on all lines, and the output at 16 comprises A-B. A suitable matrix circuit combines the final outputs with the luminance signal to obtain the component colour signals. The invention is particularly useful where the signals A+B are respectively of the form a(R-Y)+b(B-Y) and a(R-Y)-b(B-Y), since the signals R - Y and B - Y (together with multiplying factors) are obtained directly at 18 and 16. The Specification discusses the choise of the factors a and b with the object of obtaining the maximum modulation capacity of the sub-carrier and uniform noise protection for all colours. Specification 821,246 is referred to for details of the SECAM system.

Title: Improvements in or relating to machines for levelling or moulding the soles of boots and shoes
IPC: A43D89/00
Filed: 1927-03-28
Abstract: 288,430. Gimson Shoe Machinery Co., Ltd., Bagshaw, C. M., and Vyse, H., E., March 28, 1927. Sole-levelling. - Relates to machines of the kind . wherein the sole is subjected to rolling pressure between a jack or last and an oscillating form, and consists in the provision of means by which the operator may predetermine the number of levelling pressures to which the shoe will be subjected. The invention is described as applied to the machine described in Specification 252,265, having a work carriage 25 provided with two toothed blocks 26, 27 co-operating with a toothed plunger 20 carried by a reciprocating slide 17, the engagement of the plunger and blocks being determined by cams 46, 47 on a rod 45, all as described in the prior Specification. The means for predetermining the number of levelling pressures comprise a scroll cam 50 and a ratchet wheel 75, both on the shaft 45. The rachet wheel 75 is operated by a pawl 74 through a plunger 66, normally raised by a spring, and a segment gearing with a plunger 54 which is raised when the carriage reaches the rearward end of its working stroke by one of the guide rollers 24. The plunger 54 is supported by a collar 58 and nut, the collar having a flange 59 which allows alternative positions of the plunger, one as shown and a slightly higher one when the collar is reversed so that the flange is on its upper side. The operator positions a shoe on the jack on the carriage 25 and turns the rod 45 through 180‹, whereupon the slide 17 on its next rearward movement moves the carriage from work positioning to foremost operating position, and on its next rearward movement moves the shoe under the form, all as described in the prior Specification. During this rearward movement a roller on the carriage engages the cam 50 and turns the rod 45 through 90‹. Near the end of the movement the mechanism 54, 74 turns the shaft 45 a further 30 or 45‹, depending on the setting of the collar 58. Subsequent reciprocations of the carriage again operate the mechanism 54, 74 until the shaft 45 has been rotated a total of 180‹. This rotation places the cams 46, 47 in position to return the work to the front of the machine, as described in the prior Specification.
