Title: Improvements in stop circuits for textile machines
Inventor: PICKLES NORMAN
IPC: G05B19/048
Filed: 1966-05-26
Abstract: 1,128,386. Programmed electric control. BLACKBURN ELECTRONIC PRODUCTIONS Ltd. May 23, 1967 [May 26, 1966], No.23643/66. Heading G3N. [Also in Division D1] A circuit for arresting a pattern controlled textile machine having needles controlled photoelectrically through relays comprises an alarm and stopping circuit which is energized if each relay does not operate at least once per machine cycle. The pattern P reflects light to each photocell PC which through amplifier AM energizes a relay G which through a contact G1 fires a thyristor SCR by a resistor R5 energizing a relay Z which opens contact Z1 in parallel with similar contacts in similar circuits controlled by other photo-cells. Contacts Z2 illuminate a green lamp GL and contacts Z3 open. When the machine is first energized relays A, E, and slow to operate T are energized but contacts T1 are not closed until the end of the cycle time which energizes a relay D via contacts C2, R3, contacts of D1 releasing all the Z relays and contacts D2 releasing relay T. Contacts T1 release relay D after a delay due to capacitor A2 when contacts D1 reclose. If however relay G does not operate, relay Z is not operated hence at the end of the cycle when T1 closes, relay C is energized and held by contacts C1, and the delay due to CR network R3, A1 prevents momentary operation of relay D. Capacitor A2 charges slowly through contacts C2 and resistor R1 hence operating relay B. Contacts B2 discharge capacitor A2 through resistor R2 thus releasing relay B. Contacts B1 flash the lamp AL as contacts Z3 are closed, and contacts C3 operate which de-energizes the circuit SC, hence stopping the machine. Individual circuits may be cut out by a manually operated switch ST. After rectification of the fault a manual switch MR is momentarily closed operating relay D which de-energizes the thyristors through contacts D1, contacts D2 release relay T and contacts D3 releases relay C. The timing relay T may be replaced by contacts closing once each pattern repeat.

Title: Plant for making bags
IPC: B31B160/20
Filed: 1968-05-17
Abstract: 1,235,511. Plant for making bags. WINDMOLLER & HOLSCHER, and MIAG MUHLENBAU UND INDUSTRIE G.m.b.H. 17 May, 1968 [22 May, 1967], No. 23682/68. Heading B5D. [Also in Division B8] In a plant for making bags a tube-making machine feeds tube-sections 4 to a device 7, Fig. 1, for forming stacks from the tube-sections, the stacks then being conveyed on rolls 9, 10 to compacting belts 11, 12, and transferred by means 15, 16, 17 to a storage device that receives the stacks 8 and delivers them to a distributing station 19, Fig. 4 (which serves two or more end-forming machines) automatically and independently of a delivery speed and timing of the stack-forming device. As shown, the tube-sections 4 are fed in predetermined numbers to upper and lower retarding belts 2, 3 which shingle the tube-sections 4 prior to stacking at a pivoted stop 7. A predetermined number of the stacks 8 are transferred from the compacting belts to collecting tables 15, 16 which are pivotally mounted in a slanted receiving position, Fig. 1. After the transfer, the collecting table is moved into a horizontal plane and then through 90 degrees so that the initially longitudinally disposed tube-sections are delivered to the end-forming machines in a transverse orientation. Stack from table 15 is deposited on a previously deposited stack from table 16 to form a double stack. The stacks 8 are transferred to the storage device 18 which may consist of conveyer belts A, B, C, D, and E, Fig. 5, arranged one behind the other and operable independently of one another by command signals from photoelectric sensing devices situated at the transfer points between the belts. The last conveyer is also operated in response to command signals from the distributing station 19. The distributing device selectively feeds the stacks 8 at right-angles to their original direction of travel into the range of transfer rakes which carry the stacks 8 to endforming machines. Bags leaving the end-forming machines are inspected, shingled, stacked, and compacted, and resultant stacks pass by upper and lower belt systems 30, 31 to a pivotally movable belt 32, Fig. 1, and a table 33 for transfer to a delivery conveyer 34. A device is described for changing the direction of travel of the stacks 8. It may form the distribution station and/or a sampling station 13, Fig. 1, for laterally removing selected stacks 8 from the conveyer track. The device may consist of a plurality of parallel revolving endless conveyers (preferably V-belts) which extend through spaces between parallel, driven rollers, the rollers and the endless conveyers being vertically adjustable relative to each other, Figs. 6, 7 (not shown), in such a manner that the supporting surface for the stacks is selectively formed either by the rollers or by the conveyers. The conveyer track 17 may extend substantially at right-angles to the conveyer track 1-13, Fig. 1, in which case the collecting tables 15, 16 need not be rotated through 90 degrees prior to depositing their loads of stacks 8.

Title: Improvements in or relating to optical rangefinders
IPC: G03B13/18
Filed: 1955-08-17
Abstract: 799,348. Optical rangefinders. ZEISS IKON AKT.-GES. Aug. 17, 1955 [Aug. 17, 1954; Feb. 17, 1955], No. 23715/55. Classes 97(1) and 98(1) An arrangement for estimating the range of an object comprises an optical system forming a virtual image or images of the object and adjustable to vary the distance of that image from the observer, and a verifier system for focusing two separate secondary images of the said virtual image or images and so arranged that the secondary images coincide when the virtual image is at a standard distance the range being deduced from the adjustment of the system necessary to bring the virtual image to that standard distance at whidh coincidence is effected. The system may be an astronomical or terrestrial telescape, a Gablean telescope in normal or inverted position or a simple or complex magnifying lens system and the standard distance may be infinity. As shown in Fig. 4 from the diverging or parallel rays of light from the eyepiece of a telescope a beam 14 is directed by a mirror 10 to the eye 15 via a mirror 11 and a beam 14 reaches the eye directly. The images formed by the beams will coincide if the virtual image from which they come is at a certain standard distance dependent on the inclination of the mirrors 10 and 11 and the objective (not shown) of the telescope is adjusted until such coincidence is effected. The mirrors may be replaced by a variety of prism systems for selecting the two beams. To allow the telescope to be used as such while, measuring range the ranging beams may be deflected by a prism placed at the real image formed by the objective. The invention may be applied to test the setting of an objective within a photographic camera by placing an illuminated object in the focal plane, using the camera lens to produce a virtual image thereof which is observed by a system such as that shown in Fig. 4 arranged to give coincidences for a virtual image at infinity, and adjusting the objective until such coincidence is achieved. Fig. 12 shows the system applied to the focusing of a reflex photographic camera in which the optical system giving virtual image is composed of the camera objective 41, 42 and an eyepiece 43 behind which is a prism 49 carrying the reflecting surfaces 10 and 11 of Fig. 4. A mirror 44, Fresnel lens 45, field lens 46 and prism 47 are also provided. The standard distance of the virtual image is arranged for infinity so that when the objective 41 is adjusted to give coincidence of the two images of an object seen in the prism 49 the object will be in focus on the photographic film. Alternatively a separate objective may be provided fixed to and movable with the camera objective.
