Title: Band pass wave filters
IPC: H03H11/12
Filed: 1943-07-20
Abstract: 578,880. Filter circuits. PHILCO RADIO & TELEVISION CORPORATION. July 20, 1943, No. 11790. Convention date, July 24, 1942. [Class 40 (iii)] An intervalve coupling comprises a pair of circuits tuned preferably to the same frequency and coupled by means of a common impedance and by an admittance connected between their high potential ends, either or both couplings being adjustable. The couplings may be capacitive or inductive, but, as shown, comprise inductances Lh, Lk and resistances Rh, Rk which are adjustable separately. The circuit inductances may be tuned by the inter-electrode capacities of the valves and may be damped by resistances R1, R2 or by their inherent resistance. They may have some mutual inductance acting in opposition to the coupling produced by Lk which can then be made larger so as to give a larger range of adjustment. By this means the peaks of a double-humped response curve can be adjusted separately in height and position. The coupling may be used to give different characteristics to the successive stages of an amplifier so as to obtain a broad, flat-topped or other desired overall response.

Title: An improved method and means for making filter tip cigarettes
IPC: A24C5/47
Filed: 1943-07-22
Abstract: 566,234. Cigarette-making machines. GAMBLE, H., and GAMBLE, V. V. D. [Representatives of Lerner, F.], and CARRERAS, Ltd. July 22, 1943, No. 11958. [Class 130] A machine for making filter-tip cigarettes comprises a paper tube maker and cutter, a filter wad making and inserting unit, and means for inserting wads into the ends of paper tubes and conveying the tubes with their wads to filling devices which insert tobacco into the tubes, the wad making unit cutting sections from a web of crepe paper &c. and forming them into cylindrical wads which are inserted into holes in a disc rotated to feed them to the paper tubes and the tubes and wads being conveyed to a reservoir from which they are removed one by one for filling. Paper from a reel 2 passes through printing, colouring or bronzing devices 4 and over an edge paster or crimper 5 to a former 6, the resulting continuous tube being sealed by a roller 7 which co-operates with a roller inside the tube, supported by a weighted arm 8. Lengths of the tube are cut by camactuated scissors 11 and are each received by a hollow spoon which carries it to a flute in an intermittently rotating drum 16. Crepe paper 20 for the filter wads passes from a reel 18 and guide 21 to feed wheels 22, 23, a length being cut off between the wheels by scissors 24. The cut length is compressed between the concave end faces of a member 25 and a cam-actuated pusher 26 to form a cylindrical wad, which is ejected by a cam-actuated push-rod into one of the holes in a disc 33 intermittently driven by a worm. In the uppermost position, the wads are ejected one at a time by a camactuated rod 36 into a tube or spoon 37 carried by a cam-actuated rod 38. The spoon 37 carries the wad to a paper tube in a flute of the drum 16, the tube and wad being retained in the flute by a stripper pawl 39. After rotation of the drum, the tube and wad fall upon a band 40 conveying the tubes to a tobacco filling device. Tobacco from a hopper 41 is showered on a tape 43 and formed by compressing wheels into a rod which enters a slotted spoon 51. A rotary cutter severs the tobacco in the spoon, a paper tube is slid over the spoon by a camactuated rod 52, and a stripper arm 57 moving in a slot in the spoon returns the completed cigarette to the fluted drum, from which it eventually falls on a delivery band 57. True alignment of the paper tubes on the drum 47 may be ensured by a reciprocating platform 61, or the conveyer band 40 may deliver the tubes to a hopper having means for transferring the tubes one at a time to the drum 47. The output of the tube-making mechanism may exceed slightly that of the tobacco-filling mechanism, means being provided for reducing it when the supply of tubes accumulates.

Title: Improvements in or relating to the production of extruded shapes from organic thermoplastic materials
IPC: B29C48/06
Filed: 1944-06-26
Abstract: <PICT:0590689/IV/1> Organic thermoplastic material substantially free from volatile solvents is extruded, hot, into a stream of inert fluid, the stream having a temperature below the softening point of the material and travelling at high velocity in the direction of travel of the extruded body.  The body is maintained in the (comparatively cool) stream until it has become form-stable.  Fig. 2 shows an arrangement in which a screw 3 extrudes strands 9 of material through a die plate 7 into ducts 11 through which is blown compressed air from a pipe 14.  The air cools the strands, maintains them out of substantial contact with the ducts and, by frictional pull, tensions them.  The strands are cut into pellets 19 by a rotating knife 17.  There may be one pipe 14 for each duct.  The fluid may be water or aqueous solutions.  In a modified single-die arrangement, for making sheet, the air issuing at the exit end of the duct is collected and led away through a vertical pipe. Specifications 300,672, 322,557, [both in Class 2 (ii)], 371,343, 530,468, 534,243 and 570,139, [Group V], are referred to.

Repeating systems using contactmaking relays; systems using code elements distinguished by polarity of currents.-A telegraph repeating system comprises relays 20, 21 for storing signals as they are received from one line section and means for distributing them to another line section. Incoming impulses operate a relay 3 which connects one of two batteries 9, 14 to an electromagnet 7 operating a tuned reed 5 and, through contacts 8, to the contacts operated by another tuned reed 25, the frequency of which has a definite relation to that of the reed 5. preferably one-half The reed 25 is controlled by a magnet 27 in a circuit controlled by both reeds. If both reeds are in their upper positions, a positive line impulse, connects the battery 9 through contacts 8, 30 and relay 21 to the battery 29. The armature 22 prepares a circuit to contact 24. When the reed 25 reaches its lowest position, the armature 23 establishes a holding-circuit, which momentarily holds the relay 21 whilst an impulse is sent out to line 2 through armature 22, contact 24, reed 25, and conductor 40. If a negative impulse is received, the batteries 14, 29 oppose each other, so that the relay 21 is not energized and a negative impulse is sent to the line 2, when the reed 25 closes the contact 24. In the meantime a second current impulse, received when the reed 5 is in its upper and the reed 25 in its lower position, is repeated through the contacts 8, 35, to the relay 20, and a positive or. negative impulse, according to the position of the armature 36, is sent to line 2 through the contact 38 on the next movement of the reed 25.

Abstract: 243,984. Rushen, P. C., (Gordan Machine Co.). May 11, 1925. Apparatus for setting up collapsed boxes. In machines for packeting small articles by inserting a predetermined number or quantity in boxes or cartons of relatively stiff paper board or like material, for instance of the type described in Specification 212,337, the cartons are fed to the machine in collapsed formation and may be of the form shown opened out in Fig. 27, with major end flaps a', b<1> at the ends of the side walls a, b, and minor end flaps c<1>, d<1> at the ends of the narrow walls c, d. Alternatively, the cartons may have a tucking flap f, as shown in Fig. 23. The cartons are pressed forward in a guide way 14, Figs. 1 and 23, by a weight or spring so that the foremost is arrested by spring detents 18, and spring blades 30, Figs. 2 and 35, mounted on a vertically movable carrier 24 descend and enter the carton. One of the blades has an extension 30a which initially bears upon a portion of the upper flap a<1>. Upon the descent of the blades 30, associated blades 33, which are initially in contact with the blades 30 are moved laterally therefrom into the relative position shown in Fig. 36, thereby opening the carton. The lateral movement is effected by the action of a slope 38, Fig. 2, on rollers 40. At a certain stage in the descent of the blades, catches 42 engage the upper edges of the carton flaps and push the carton positively downwards into the position shown in Fig. 11. The descent causes the folding in of the lower minor flap d<1> against an inclined member 44. The lower minor flap is meanwhile inserted between members 45, 46. The carton is now between the arms 75, Fig. 1, of carriers on endless chains 59, and is moved to the left, Fig. 11, folding down the minor flap c<1> upon the member 46. The lower flap a<1> has meanwhile been forced outwards by a guide 77 and the inclination is increased by a fixed curved rod 78 so as to expose the flap for the application of adhesive by rolls 80, Fig. 3. The rolls are loosely journaled in bearings in an arm 81 oscillated so as to transfer adhesive from a supply roll 88 to both sides of the flap. While moving to the next station the gummed flap a<1> is folded into the position shown in Fig. 29 by a fixed curved rod 93 and the other flap b<1> is also folded up by an inclined member. In a modification, the end may be closed by tucking in extensions f, Fig. 23, by means of curved guides.
