Title: Improvements in propeller pencils
IPC: B43K21/14
Filed: 1934-02-26
Abstract: 422,517. Pencil holders. JORGENSEN, K. V., 59, Tranegaardsvej, Hellerup, Denmark. Feb. 26, 1934, No. 6209. [Class 146 (iii)] In a magazine pencil holder having rotary mechanism for projecting the lead to writing-position, a spiral guide is mounted in the magazine compartment and a member is provided to slide in the guide to bring a new lead into position beneath the propeller. The propelling - mechanism consists of a propeller 17 having a lateral projection 18 passing through a longitudinal slot in a rotary tube 13 into a helical slot in a normally stationary tube 11. The tube 11 is secured in a sleeve 9 loosely mounted in a flanged sleeve 5 screwed into the barrel 1 and serving, if desired, to hold a pocket clip 7. The sleeves 5, 9 are provided with cooperating projections 8, 10 respectively. A cap 16 is secured to the tube 13, which is flanged at the forward end and supports a coupling-member 19 containing a compression spring 21 acting between the member 19 and an inner member 23 in which the tube 11 is carried, so that under certain conditions, dependent on the compression of the spring 21 and the friction between the parts, the member 19 is connected to both tubes 11, 13. The member 19 carries a rotatably-mounted pin 26 eccentrically arranged relatively to the axis of the barrel and the pin is provided with a part 28 arranged to slide in the passage in a spiral guide 25 fixed in the magazine compartment 4, the inner turn of the guide being of the same diameter as the leads and located concentric with the axis of the barrel. In use, after a lead is exhausted, the cap 16 is rotated backwardly, and the friction between the parts causes the tubes 11, 13 to be rotated together until the projection 10 strikes the projection 8, when relative rotation commences to cause retraction of the propeller. The rotation of the member 19 causes the part 28 to be withdrawn from the inner part of the guide 25. When the propeller is withdrawn to the rear end of the tube 11, reverse rotation of the cap again causes rotation of the member 19 until the part 28 has pushed a lead from the magazine into feeding position, when the member 19 is held against further rotation and permits the propeller to move forward. In a modification the guide is attached to the member 19, and the pin 26 is secured to the tip.

Title: Noise pulse suppression circuit particularly for the vision channel of a television receiver
IPC: H04N5/21
Filed: 1946-02-28
Abstract: 608,710. Automatic noise suppression. BLACKLER, E. R., and PYE, Ltd. Feb. 28, 1946, No. 6212. Drawings to Specification. [Class 40 (vi)] A noise pulse suppression circuit, particularly for the vision channel of a television receiver comprises as a negative feed-back circuit between output and input electrodes of the amplifying valve a rectifier shunted by a resistance in series with a condenser. The condenser is normally charged to peak white level and a small amount of negative feed-back is applied to the valve, the time constant of the series resistance capacity circuit being long. When a short duration noise pulse of greater amplitude than peak white is received the rectifier conducts, a large amount of negative feed-back is applied to the amplifier thus reducing or eliminating the effect of the noise pulse.

Title: Improvements in duplicating machines
IPC: B41L11/00
Filed: 1936-03-03
Abstract: 455,956. Duplicating - apparatus ; printing-surfaces. DITTO, Inc., 2243, West Harrison Street, Chicago, U.S.A. March 3, 1936, No. 6421. Convention date, March 9, 1935. [Class 100 (ii)] A duplicating-machine comprises a rotatable drum carrying a clamp for the master sheet from which copies are to be made, and mechanism for guiding the master sheet to the clamp and for stopping the drum with the clamp open and in alignment with the sheet guide. The clamp is formed by a bar 85 held in a recess in the drum 32 by springs 85a and spring-pressed to clamping-position, a bar 88 slidable longitudinally in the drum and formed with recesses engageable by rollers on the bar 85 serving to release the clamp. In order to replace a sheet carried by the drum, a lever 93, normally held against a stop 93b by a spring 102, is rocked so that a pin 101a, engaged by a notch in the lower end of the lever, is released. The pin 101a is secured to the inner end of a table 76 pivoted in the side frames of the machine at 77 and carrying a bracket 78 to which is pivoted an arm 79 pressed against a lug 103 on the inner end of the table by a spring 82, and formed with cam surfaces 80, 84 and a shoulder 94. The released tableswings to horizontal position wherein it is held by the lug 103 engaging the arm 79, the lever 93 being retained in locked position by the pin 101a. The cam 84 is thus swung into position to engage the projecting end of the bar 88, which, on rotation of the drum, is moved to cause the clamping- bar to release the master sheet. A pin 81 on the drum then slides over the cam surface 80 and snaps over the shoulder 94, in which position it engages the end of the lever 93 to stop the drum with the opened clamp opposite the table 76. A new sheet is pushed into the clamp, and the drum is rotated rearwardly. A cam 95 on a spring-pressed lever 96 engages the end of the bar 88 to return it to the position in which the bar 85 can grip the sheet. The pin 81 pulls the arm 79 downwardly, rocking the table 76, so that its end remains in alignment with the clamp, until the pin 101a is in a position to be engaged by the end of the lever 93 which is then pulled by the spring 102 so as to release the pin 81 and permit normal rotation of the drum. The lug 103 on the table restores the arm 79 to normal position.

Filed: 1940-04-16
Abstract: 540,493. Shuttleless looms. LUCAS, J. April 16, 1940, No. 6880. [Class 142 (ii)] A loom of the type in which the weft filling is drawn from yarns fed from separate supply sources at opposite sides of the warps is provided with two weft-sinserters 29 reciprocable in opposite phase through the shed, each member 29 taking a double weft in loop form to the middle of the shed where the weft is transferred to the other member 29 which takes the loop to the other selvage. Each member 29 has a latch or jaw element 33 secured to a rod 35, and cams are arranged upon a fixed cross beam to engage pawls 38, 39 operable upon the rod 35 to open or close the latch 33. The cams are so arranged that the latches of both weft-inserters 29 open at the middle of the shed to effect transfer of the looped weft and then close, the latch of the member receiving the loop being opened to release the weft beyond the line of the selvage and the latch of the returning member being opened in its return stroke to release the yarn it embraces. Means for tensioning the yarns at each side of the warps are provided. Latch needles 62 and hook-ended temples 66, 67 are provided at each side of the warps for locking the bights of the double wefts to form the selvages. Each temple engages the fell of the double loop last laid from its side and forms a turning point from which the next double loop can be laid from that side. Each latch needle 62 engages the loops laid from the opposite side of the warps, and to facilitate engagement of the needle with a loop, pins 59 project outwardly from the reed 49 in the plane of travel of the members 29, and in the beat-up separate the limbs of the loop and position it for reception by the needle. A deflecting member 61 also serves to ensure the positioning of the loop upon the latch of the needle. The latch needle draws the loop from the pin through the previously laid loop which is already on the needle and casts the previously formed loop over the new loop to form a locking stitch.
