Title: Filters and carbon monoxide indicators
IPC: B01D53/14
Filed: 1971-10-25
Abstract: 1369067 Separating gases using heme or hemoglobin I H SCHEINBERG 25 Oct 1971 [29 Oct 1970 30 Dec 1970] 49365/71 Heading C1A [Also in Divisions A2 and G1] A composition is used as the active element in a filter unit, which composition comprises a mixture of a reductant with crystalline hemoglobin, amorphous hemoglobin, amorphous heme or crystalline heme wherein heme includes hemin, the reductant being in stoichiometric excess relative to the iron content of the hemoglobin or home and having an oxidation reduction-potential such that it absorbs oxygen from air or smoke more strongly than does heme or hemoglobin. The said active element is particularly adapted for the removal of carbon monoxide from gas streams when the colour change of the hemoglobin or heme to cherry red can be monitored visually or instrumentally, or the change in infra-red absorption may be monitored instrumentally to indicate when the filter unit is exhausted. If desired the filter unit may be replaced mechanically. The preferred reductants are ascorbic acid and methylene blue. Gases in addition to carbon monoxide may be removed from the gas stream by forming the hemoglobin under acid or under alkaline conditions before utilizing it in the filter element. As shown in Figs. 1 and 2 the filter element may be used to filter tobacco smoke either by being incorporated in a cigarette 10, or in a cigarette holder 24. The cigarette wrapper 12 may incorporate a transparent portion 22 and the holder may incorporate a supporting chamber 30 with transparent window 34, so that the smoker may ascertain visually that the filter is exhausted. The filter in support 30 is replaceable. A more general system for removing carbon monoxide or warning of its presence is shown in Fig. 3. A sheet or membrane of the hemoglobin containing composition may be rolled on supply roll 42, and may be unrolled on to take up roll 46 past a stream of air 48 which may contain carbon monoxide. A beam of light from source 50 passes through the membrane to impinge on cell 52. As the properties of the membrane change with its Co content the light detected by 52 will vary correspondingly. At a predetermined level, the detector control may be adapted to sound an alarm or perhaps merely change the exposed membrane by operating the roller. The membrane or other filter may be regenerated by incorporating a blower unit in the system adapted to direct a stream of oxygen or air substantially free from carbon monoxide over the loaded filter when the absorbed Co may be displaced and collected.

Title: Improvements in and relating to character recognition
IPC: G06K9/20
Filed: 1964-12-04
Abstract: 1,069,214. Automatic character reading. RADIO CORPORATION OF AMERICA. Dec. 4, 1964 [Dec. 23, 1963], No. 49506/64. Heading G4R. A character reader has means for reading characters on a document and also handwritten marks, both being sensed to generate signals and means being provided to distinguish characters and marks. The characters are printed in a special font, Fig. 2 (not shown), in which they may be distinguished by different combinations of vertical strokes in the right-hand zone and a combined centre and left-hand zone. The handwritten marks (20) are in the form of long vertical strokes which are long enough to extend above and below the limits of the scanned area. The image of the characters or marks on the moving document are projected on to the screen of a camera tube and scanned by a series of vertical strokes. After clipping and the filtering out of short spurious signals the character signals are sampled by being shifted into a four-stage shift register, the output of which is applied via a control circuit to first one shift register and then to a second shift register. The control circuit is governed by a scan counter so as to enter the signals from the right-hand zone of the character into the first shift-register and those from the centre and left-hand zone into the second. Both shift registers have re-circulating loops so that the black signals re-cycle, but each black line is entered only twice. At the end of the character, determined by the occurrence of an all-white stroke, the circulation of the signals in the registers is stopped and started again under the control of a positioning device. This consists of a series of gates arranged to look for the top of the vertical stroke in a particular stage of the register. When the pattern reaches this position the supply of shift signals is interrupted and the recognition circuitry is enabled to identify the character. If there is a handwritten mark pattern in the register it becomes impossible to register the pattern since there is no white portion giving a top end to the vertical stroke. When the registry circuit fails to find a top end it causes a flip-flop to be set to indicate a handwritten mark. This signal also disables the normal recognition circuit.

Abstract: 1,128,778. Packaging-machines; suction lifting heads. AMERICAN MACHINE & FOUNDRY CO. 3 Dec., 1965 [15 Dec., 1964], No. 51375/65. Headings B8C and B8H. A group of articles such as buns, rolls, are transferred from a tray T, Fig. 5, to a container K, Fig. 2, by an oscillating vacuum pick up head H, the empty tray being removed by a conveyer 130, Fig. 1. In the embodiment described, a tray containing buns is moved by a pair of endless conveyers C, Fig. 2, to beneath an oscillating vacuum pick-up head H, whereupon the tray T, Fig. 5, is held stationary by fingers 84 engaging beneath the tray and rollers 96 and 110 pressing against the top surface of the tray. To assist removal of the buns, the surface of the tray is first blasted with air through nozzles 352, after which the suction cups 158 of the pick-up head H engage the top surfaces of the buns. The suction cups 158 are suspended from blocks 160, Fig. 6, which are slidably supported on transverse rods 210, 216 and 222 and longitudinal rods 230. A U- shaped member 232, secured on a longitudinal rod 230, is connected by links to the transverse rods 210 and 222 and also to an air cylinder 218, the actuation of which, during the upward movement of the pick-up head H, causes its pistons to slide towards each other over the transverse rod 216 moving the blocks 160 and hence the buns into contiguous engagement. During movement of the pick-up head H, which is oscillated by a connecting rod 202, Fig. 1, secured to a sprocket 194 driven by an endless chain 198, a carton K, Fig. 2, is released by a finger 284 actuated by an air cylinder 290. The carton K is moved on a conveyer 260 to a pair of plates 294, oscillated by a cam mechanism, which plates push the carton on to tilted U-shaped cradle bars 298, Fig. 5. The suction on the buns is then released by a sliding valve 180, Fig. 1B, not shown, to cause them to be deposited into the carton resting on the cradle bars, the rear wall of the carton being bent backwards by a finger 342, to facilitate packaging. Finally, the cradle bars 298 are tilted by cam mechanism to deliver the filled carton on to a conveyer 380. After the buns have been extracted from the trays, the empty trays are pushed from the end of the conveyers C by rods 120 (Fig. 2), on to a pair of tray return conveyers R positioned directly below the in-feed conveyers C. The machine is controlled by a pneumatic control system, the valves being secured on a ring member (416), (Fig. 4, not shown), surrounding a drive shaft (196) on which is keyed a cam (418) which actuates the valves as the shaft (196) rotates. Also, a tray sensing valve 428, (Fig. 2) and a carton sensing valve 430 are interconnected to prevent carton feeding when a tray is absent and vice versa. A channel (82), (Fig. 2A, not shown), for guiding the trays is disposed between the two infeed conveyers C, which may be vertically pivoted to compensate for variation in tray and bun heights.
