Title: Improvements in and relating to textile spinning and like frames
IPC: D01H9/04
Filed: 1933-04-11
Abstract: 415,842. Doffing -arrangements for spinning and like frames. FRASER, G., FRASER, N., and FRASER, J., Westburn Foundry, Arbroath, Angus. April 11, 1933, No. 10770. [Class 120 (ii).] In a self-doffing spinning and like frame employing a stripper for removing the full bobbins when the spindle rail is lowered and a swing carrier for the empty bobbins, the empty bobbins 4 are carried by a rack or holder 5 which is pivotally mounted on a lever arm 6 and is connected with a link anchored to a pivot 11 adjacent to the pivot 7 of the arm 6 so that, when the arm 6 is moved to the position shown in dotted lines the empty bobbins are aligned with the spindles 2 and are impaled thereon when the spindle rail is raised to the spinning-position. The spindle rail and the lever 6 may be independently operated by hand gear, or the lever may be operated to and fro as required by an adjustable striker moving with the spindle rail. The full bobbins are doffed and fall into a trough 12 or on to a conveyer when the spindle rail is lowered out of traverse by means of a stripper plate 17 carried by a lever 18 operated so that, when the spindle rail has been raised slightly to the position x after the initial lowering from traverse to provide a length of slack yarn y, the plate is advanced to support the bobbins and to strip them upon further lowering of the spindle rail. The Provisional Specification comprises also a stripper plate which moves with the spindle rail during normal traverse, but is arrested when the rail is lowered beyond the traverse, and for tipping the bobbins rearwardly of the frame bars, hinged to vertically sliding rods and moved relatively to the spindle rail.

Title: Automatic machining process for blanking dies
IPC: B21D37/20
Filed: 1966-03-14
Abstract: 1,135,663. Making blanking dies. ING. C. OLIVETTI & C. S.p.A. 14 March, 1966 [13 March, 1965], No. 11014/66. Heading B3A. In a process for making blanking dies comprising parts with complementary blanking profiles, each part is milled to the profile using a machine tool whose tool path is continuously controlled by a recorded programme, reference formations are machined in the part, which is then heat treated, and the profile is finished by a machine tool again controlled by a recorded programme. The programme is recorded in digital form on a tape, which is prepared by a programmer first compiling a symbolic programme containing the dimensions of the profile and the tool movements required. This programme is prepared and fed to a computer, which determines the path the centre of the tool has to follow. A control tape for the automatic control device of the machine is prepared from the computed data. A blank has reference holes 14, 15 drilled and reamed therethrough and is placed on a milling machine work-table fitted with dowels which locate in the holes 14, 15. The lower face of the punch is then milled and after milling is turned over, the holes 14, 15 again registering with the dowels. The working face of the punch is then milled to a slightly greater dimension than the lower face. Since a mirror image of the lower face is being milled the same programme can be used for both faces, it being only necessary to reverse all the co-ordinates recorded on the tape. The difference in dimensions is obtained by a correcting device of the type described in Specification 926,524. The milled blank is heat treated and then placed on the table of a grinding machine. As it may have deformed during heat treatment, two-diameter dowels are used to locate it. If necessary, the blank is examined microscopically and displaced under the control of the programme tape to ensure that sufficient excess metal is present all round its periphery to allow for grinding. The blank is then clamped, the dowels removed, the reference holes opened out to the required dimensions and further dowels inserted to locate it on the machine table. The blank is then ground under control of the control tape and the same grinding wheel may be used for grinding the blank profile and the reference holes. The matrix is made in a similar manner to the punch and the same programme tape can be used, by employing either tools of different diameters or a correcting device as before, to obtain the necessary clearances. Die parts mounted integrally on a base may also be made by this method, Fig. 3 (not shown).

Filed: 1947-04-29
Abstract: 623,313. Paper bags. PAPER SACKS, Ltd., and ROBINSON, P. G. April 29,1947, No. 11420. [Class 94(ii)] A multiply blockbottom bag of the kind in which the plies overlap at the margins has a valve tongue formed integrally on a selected ply, preferably the innermost one, or, where the latter is a barrier ply, the innermost but one. The bag is made by perforating the webs for the plies on transverse lines, a suitable ply 1 being so perforated as to leave a longitudinally projecting integral tongue 3 at the head of one bag length with a corresponding recess 7 at the tail of the next adjacent length. The tongued and the other webs are assembled with the perforations in stepped relation into a bag tube, and bag lengths are formed from the latter by rupturing the plies under tension. The figure shows a bag length opened out, the transverse lines indicating the lines of rupture. Subsequently the blockbottom valve closure is formed with the said tongue extending inwardly to function as a sealing member. The width of the tongue is substantially the width between the transverse folding lines of the blockbottom closure. In a modification the tongue is made at least double the aforesaid width to give the tongue a tubular form. Specifications 343,447, 443,920, 443,950, 459,377, 486,430 are referred to.

Title: Improvements in or relating to adjustable coupling devices for high-frequency alternating voltages
Inventor: THIRUP GUNNAR
IPC: H01P1/18
Filed: 1952-05-06
Abstract: 709,676. High-frequency coupling devices. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 6, 1952 [May 9, 1951], No. 11436/52. Class 40 (8) A high-frequency coupling device comprises two mutually perpendicular input loops 3, 4 situated within a cylindrical waveguide 5 and an output loop 1 rotatable about the axis of the guide. A rotating magnetic field is produced by the loops 3, 4 whose fields are of equal amplitude but 90 degrees out of phase with respect to each other. It can be shown that the voltage induced in the output loop 1, when this loop is at an angle α to a horizontal line perpendicular to the axis of the rotational field, is equal to V sin (#t+α), i.e. the output voltage has a phase angle equal to α and an amplitude independent of α. This is only true when the magnetic fields are homogeneous, a condition not realizable in practice. If, however, the loop 1 is coupled to the rotational field by the cylindrical waveguide 5 whose diameter d is smaller than .578 times the wavelength # corresponding to the frequency of the rotational field, the inhomogeneit'es in the field are damped out and a pure circularlypolarized H 11  mode field is produced near the loop 1. The best suppression of undesired waveforms occur when d <#/10.
