Abstract: 1417793 Feeding and delivering sheets XEROX CORP 8 May 1973 [16 May 1972] 21873/73 Heading B8R A document processing device (e.g. a facsimile receiver/transmitter) comprises means to feed a document along a path to a processing station, means for retaining the document in registered position at said station in response to a signal indicating proper positioning of the document at said station and means for removing the document after processing. Feeding sheets.-Documents 32 separated from the bottom of a pile by friction belt 68 which co-operates with a block 72 for preventing feed of more than one document are forwarded between guides 74 and 76 to feed roller sets 84/88 and 86/92. Detection of the leading edge of a document by a detector 96 disables the belt 68. The feed roller sets continue to feed the document until its leading edge abuts the registration surface 102 of a gripper 104 carried on processing drum 98. Buckling of the document on contact with the gripper is sensed by a detector 116 which detector causes disabling of the feed roller sets and closing of the gripper. The drum is then cycled for processing the document (e.g. scanning by means of a scan head 130 mounted on a carriage 134 movable axially of the drum 98). Delivering sheets.-Following completion of processing a rotary solenoid 226 is energized to release the gripper 104 and lower stripping rollers 182 into contact with the document. These rollers cause the document to pass along guide 214 to transport rollers 208 which complete delivery to receiver 212. A detector 206 senses passage of each document and permits initiation of the next processing cycle.

Title: Improvements in or relating to selvedge guiding apparatus
IPC: B65H23/032
Filed: 1936-08-11
Abstract: 483,225. Guiding webs. FOXWELL, D. Aug. 11, 1936, No. 22076. [Class 100 (i)] In apparatus for guiding a web trans versely, the move ments of a feeler engaging the edge of the web are caused to actuate mechanisn for axially moving the shaft of the wet supply roll to restore the web to its correct path, and a catch, normally held inoperative by the web, is provided for engaging and holding the feeler against movement when the web is exhausted or breaks. A feeler blade 15, mounted on a pivot 14 and connected to a source of electric current by a wire 21, engages the edge of the web and movement in either direction causes its lower end to make contact with one or the other of a pair of contacts to close a circuit to a reversible electric motor which drives, through chain-andsprocket gear, a nut threaded on the end of the supply-roll shaft, the nut being held against axial movement so that the shaft is moved axially to restore the web to its correct path. A rod 29 carried by one or a pair of counterweighted pivoted arms 27 normally rests on the web or engages its undersurface, and carries a forked catch 32 normally clear of the feeler. When the web is exhausted or breaks, the consequent movement of the rod 29 carries the catch into engagement with the feeler to hold it against movement and'thus prevent undesired actuation of the motor. The feeler may actuate pneumatic instead of electric means for controlling the roll-shaft actuating mechanism.

Abstract: 585,247. Capacity measurements. COSSOR, Ltd., A. C.. and ROBINSON, F. C. Nov. 13, 1944, No. 22335. [Class 37] [Also in Groups XIX and XXXVIII] An apparatus for indicating the roughness of a surface comprises a stylus and a condenser whose capacitance varies in response to the movement of the stylus in following the undulations of the surface. A stylus 17 is secured by screw 18 to one end of a horizontally pivoted member 15 to whose other end is connected a flat condenser plate 19 movable between fixed condenser plates 11, 12 so forming a differential condenser whose capacitance varies in accordance with the vertical movement of the stylus 17. The parts 17, 15, 19 are balanced about the pivot 16, the stylus being pressed down by the action of the hair spring 20. The differential condenser together with condensers 26, 27 forms a bridge circuit (Fig. 3) one diagonal of which is fed with a 50 volt wave at 1,000 c/s, and as the capacitance varies, an amplitude modulated voltage appears between earth and connexion 29. This voltage is amplified and detected at 30 and fed to indicating means 31 such as a microammeter. Calibration of the instrument is made by noting the deflection caused in 31 by the insertion of condensers 32, 33 into the circuit as shown. The plane from which the roughness is to be measured is set by screws 23 which slide over the surface and movement of the head over the surface may be automatic or manual. Condensers 26, 27 are selected so that the bridge is always unbalanced so ensuring that 100 per cent. modulation, and hence sense ambiguity of the meaning of any given value of the output, is avoided. Recording the state of the surface may be carried out by running the stylus over the surface in synchronism with a recording micro-ammeter.
