Abstract: 728,254. Feeding sheets; stencilling-apparatus. GESTETNER, Ltd. Oct. 1, 1953 [Jan. 21, 1953], No. 1784/53. Classes 100 (1) and 100 (2). In apparatus for separating sheets in succession from a pile 13 resting on a table 12 by friction rollers 26 which are reciprocated over the pile and which are locked against rotation on the sheet-feeding stroke, the upper surface of the table 12 is slotted or grooved at 48, Fig. 3, beneath the tracks of the rollers 26, and a raised friction surface 57 is disposed between the grooves &c, This arrangement prevents the pile as a whole being moved by the rollers when the pile is nearly exhausted. The apparatus is shown as applied to a stencilling-machine comprising a stencil 19 supported by cylinders 17, 20 which are driven through gearing 18 by a handle 16. The rollers 26 are supported by a frame 27 pivoted on a pin 28 carried by an arm 29 attached to a carriage 30. The carriage is supported in guides 31, and is slotted to receive a pin 34 on an arm 32 pivoted at 35 to the frame 10. The pin 34 can be released by cam action on moving a lever 37. The arm 32 is connected by a link 33 to a crank pin on a gear 18, whereby the carriage and rollers are reciprocated. The rollers 26, which have serrated rubber peripheries, are secured to a spindle 40 having two grooved discs 42 secured thereto which are engaged by cam-faced, spring-urged pawls 43 allowing the rollers 26 to roll freely on their outward stroke and locking them against rotation on their inward stroke, thereby feeding the top sheet of the pile 13 into the machine. The upper surface of the table 12 has two grooves or slots 48 beneath the tracks of the rollers 26, and is slotted to receive a removable plate 55 carrying a strip 57 of sandpaper or other rough material disposed below and between the roller tracks. When the pile 13 is nearly depleted, the remaining sheets are deflected into the grooves 48 by the weight of the rollers, and the intermediate part of the pile is pressed against the strip 57 to prevent the pile as a whole being moved. A stop arrangement prevents the rollers 26 engaging the bottoms of the grooves 48. The edges of the pile 13 are engaged by rubber &c. pads carried by holders 21 as described in Specification 727,182. The roller assembly may be folded against the side of the frame 10. The arm 29 is mounted in brackets 61, 62 secured to the carriage 30 by means of a cross pin 60 (not shown) and is urged by a spring 61 so that two studs 64 on the arm engage in holes in the bracket 62. The arm 29 is released for folding upwardly by depressing an extension 63 of the pin 60. The frame 27 is prevented from pivoting about the pin 28 by the engagement of a peg 70 on the pin with a slot 74 in the frame.

Abstract: 688,666. Impedance networks. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 25, 1951 [Feb. 8, 1950], No. 1946/51. Class 40 (viii). A coupling network for ultra-high frequencies comprises a fixed capacitor 10, a shunt inductance provided by parallel transmission lines 11, 12, a variable short 15 for varying the resonant frequency of the circuit, and coupling capacitors 8, 9 connected to the inductance at points C, D thereon such that the band width of the network at the maximum and minimum tuning points is substantially equal. The circuit shown is a shunt filter circuit in the input of a television receiver and may form one of a series of resonant circuits connected as a three-section band-pass filter which is tunable over the ultra-high frequency band. It can be shown that the coupling capacitors 8, 9 must be variable in order to obtain constant band width over the tuning range of the circuit. The effect of variable capacitors can, however, be obtained by connecting fixed capacitors 8, 9 to points C, D on the inductive branch of the resonant circuit which are intermediate the connecting point of the capacitor 10 and the minimum tuning position A of the shorting member 15.
