Filed: 1933-10-23
Abstract: 417,897. Printing-machines. PATIENT, J., Woodcote, Elm Park Road, Pinner Green, Middlesex. Oct. 23, 1933, No. 29300. [Class 100 (i).] Feeding sheets; delivery apparatus.-Sheets are fed from a pile to printing &c. machines by means of a suction device mounted on a carrier 6 which is reciprocated in fixed guides 8 from a crank motion, and the suction device is also given an angular motion by means of a gear 15 engaging a fixed rack 16 so that its path is cycloidal. The carrier 6 is reciprocated from a crank 1 adjustably secured to a driving-shaft 2, and the suction device consists of nozzles 14 secured to a hollow bar 10 fitted with crank arms 11 pivotally mounted through hollow pivots 12 in hollow arms 7 on the carriers 6. Air is exhausted from the carrier 6 and bar 10 by means of a suction pump 23, the piston of which is reciprocated by a crank-pin 36<a> on a shaft 19 driven by a chain 34 from the shaft 2. The crank-pin 36<a> acts on a slotted lever 36 to move the piston positively in each direction in such a manner that the return stroke of the piston is faster than the forward stroke. At the commencement of the separating action the nozzles are given a quick tilting action by means of a cam-actuated tappet 17 which engages a roller 20 on a projection of the crank arm 11 and moves it against the action of a spring 21 so as to curl up the edge of the sheet as it is lifted from the pile. The separated sheet is carried between positively driven rollers 25, 25<a>, the lower set of which is raised to grip the sheet by means of a lever 26 actuated from a cam on a shaft 18 driven from a shaft 19 which by means of a chain 33 and tapes 31 drives the rollers 25. The sheets are finally advanced to adjustable front stops 64 which are depressed after the sheet has been printed by a reciprocating head 82 fitted with inking- means as described in Specification 417,914. On depression of the front stops 64, delivery rollers 80 are moved on to the printed sheet. The pile table 24, Fig. 4, is raised by screws operated by a ratchet 47 and a pawl 46 on a lever 45 which is oscillated by a cam 43 on the shaft 42. The pile is only raised when a fullstroke is given to the lever 45. When the pile is raised a screw 58 acts on a lever 59 and causes this to restrict the movement of the lever 45; otherwise the lever makes a fullstroke. The screw 58 is controlled by a dabber 57 which is oscillated to and from the top of the pile by a cam 50, lever 52, and a spring- controlled link 54 acting on an arm 55 on the shaft 56 of the dabber.

Title: Improvements in or relating to voltage regulators and the like
IPC: G05F1/52
Filed: 1929-09-30
Abstract: 336,771. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Hansell, C. W.). Oct. 2, 1928, [Convention date]. Regulation, automatic.-A method of voltage regulation of a D.C. circuit liable to extremely rapid load fluctuation, e.g. the supply circuit of a wireless transmitter 2, includes, in series with the supply, a triode valve 10 whose impedance is automatically varied, inversely with the load current. A resistance 12 in series with the line is used to control the grid bias of a second valve 14, the anode of which is connected in series with a resistance 16 which controls the grid bias of the valve 10. As the load current increases the grid potential of valve 14 is lowered and the current in resistance 16 decreases. This decreased flow decreases the potential difference between the grid and anode of valve 10 thus decreasing the impedance of valve 10 and maintaining constant voltage at the transmitter terminals. An overload relay 18 short-circuits the valve 14 on overload and the resulting increase of current flow through the resistance 16, together with the action of the bias battery 20, raises the impedance of valve 10 sufficiently high to cut off current to the transmitter, the valve 10 thus acting as a circuit-breaker.
