Title: Improvements in movement amplifying devices for indicating instruments
IPC: G01D5/04
Filed: 1947-03-10
Abstract: 642,723. Indicating-apparatus; gauging- apparatus. MALEC, M. M. March 10, 1947, No. 6666. Convention date, March 26, 1942. [Classes 106(ii) and 106(iv)] [Also in Group XX] A movement-amplifying device for an indicating-apparatus wherein displacement of a contact member is transmitted to a main indicator through intermediary mechanism by rolling friction between rollers and slide members is characterized in that the roller which supports the main indicator is pressed between two intermediate members moving in opposite directions, at least one being a slide member, and does not itself participate in the transmission of the efforts which produce the movements of the members. A dial gauge comprises a shank 2, Fig. 2, for a contact member 3, with a knife edge 18 supporting a beam 19 bearing against a fixed knife edge 20 and a knife edge 21 on a slide member 10. Knife edges 24, 25 on slide members 10, 11 support a second beam 22, which is held in contact with a fixed knife edge 23 by a spring 17. The slide members 10, 11 bear against opposite sides of rollers 12, 14 and are so clamped through ball or roller bearings 8, 9 and 16 by a resilient plate 15. The rollers 12, 14 are of different diameters and their spindles carry pointers to indicate movements of the contact member 3 in units of different orders. In the embodiment shown in Fig. 4 a member 18a on the shaft 2 pushes a sliding member 10a against a spring 17a and a spring 33 biasses an arm 31, pivoted to the member 10a, so that the two members 10a and 31 roll on interengaging rollers 12a, 14a whose spindles carry pointers. In another embodiment, Fig. 5, the member 18a pushes a slide member 10b, between which member and a second slide member 11b are clamped rollers 12b, 14b. Two rollers 12b are provided and between them a pinion 12c meshes with rackteeth formed on the slide members 10b and 11b. In two further embodiments, the larger roller has a pointer elongated to form a ruler which co-operates with a fixed ruler to form a protractor (see Group XX). In another modification, Fig. 13, a dial indicator has a large contact member forming a slide member 60 retained between rollers 61, 62 and 63 which are themselves clamped by a resilient ring 64 with a roller 65 between the ring 64 and roller 63. A roller 12g carrying a small pointer is clamped between rollers 61, 62 and an index is carried by the ring 64. Zeroizing. Means for setting the pointers to zero in any position of the contact member, Fig. 10, comprise two press-buttons 37, 38, the first for lifting the slide-members through a spring-biassed bell-crank lever 39, the second for extending the spring 33e, to free the rollers 12e, 14e from co-operation with the slide members, and through a toggle system to cause a lever 49 to bear on a cam 53 on the spindle of the roller 12e for setting the pointers to zero.

Title: Folding machine
IPC: B65B63/04
Filed: 1972-02-14
Abstract: 1383701 Feeding and folding sheets D MANTOVANI 14 Feb 1972 [23 Feb 1971] 6729/72 Heading B8R Feeding sheets.-Sheets F, Fig. 1, are fed alternately from two magazines 3, 3a to a buckling folder. Sheets in the magazine 3 rest on edge on a base plate 17 and are pressed against a plate 4 by a spring-urged cylinder 22, a side guide and the cylinder 22 being adjustable according to sheet size. Each sheet is separated from the pile by a circular sector-section oscillating suction device 45 and introduced between rollers 46, 47, whereupon it is fed through a channel 56, between rollers 65, 66 and through a second channel 67 and an oblique slot 114, Fig. 9, in a plate 113 to the folder. Sheets in the magazine 3a are separated similarly and fed through a single channel 68. The plate 17 is formed with a comb at its front edge, below which is fixed a plate 36, Fig. 10, having a plurality of nozzles 37 for blowing air for riffling the sheets, and pointed screws 38 to pass between the sheets and prevent double feed. Folding sheets.-A buckling folder comprises a plurality of rollers arranged in vertical planes in two groups 69, 70, 71, 72, 77 and 73, 74, 75, 78, Fig. 9, and tangential to each other. Between rollers 70, 71; 71, 72; 73, 74 are arranged pairs of frames as 119, 120 defining a gap between them in which is an adjustable stop as 123, while concave-ended plates 113, 132, 138, 140 are arranged between the other pairs of rollers. In operation, sheets arrive from magazine 3a at rollers 69, 73 or from magazine 3 at rollers 70, 73, and are then directed by beak portions as 126 of the frames into the gaps against the stops to be buckle-folded into the next pair of rollers, while being guided round the rollers by the plates, the folded sheets being removed by conveyers 78, 79. The rollers are mounted on resiliently mounted arms to be pressed together and rotate at twice the speed of the sheet feed rollers.

Patent GB-439551-A (GB)
Title: Improvements in and relating to the beaming of the warp for hand looms
IPC: D02H13/16
Filed: 1934-03-05
Abstract: 439,551. Hand-loom weaving. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCHE WOLSPINNERIJ, Amsterdam. March 5, 1934, No. 6919. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 5, 1934]. [Classes 142 (i), 142 (ii), and 142 (iv)] In beaming the warp for hand looms with rotatable beams, the warp is wound in a single continuous length alternately around the pins of two combs 9, 11, one at least being set up outside the loom frame at a distance from the other comb, providing an extra length which is wound up before the weaving commences. During weaving the combs may be used as the beams or are inserted in the beams. As shown in Fig. 3, the breast beam 4 with a comb 9 thereon, may be removed from its support 3 in the loom during the warping, the thread being passed around the pins on the combs 9, 11 and through the spaces between discs 13 on a shaft 1 and resting on eccentrics 14 thereon, or one of the combs may be removed from its roller during the beaming. Various means for removably fixing a comb into a beam, and for clamping the warp into a beam are described. Thus the beam 17, Fig. 5, may have a journal 18 formed with a slot 19 whereby it is rotated. The comb 21 having teeth 22 rests in a longitudinal slot in the beam and is provided at each end with a member 23 having a lug 24 resting in a depression 25 in a circular plate 26 fixed to a bush 27 turnable on the beam. It is first raised, the bush 27 is then rotated so that the part 24 passes into a deep depression 29 in the plate leading into a bayonet slot in the bush and the comb is then locked in position by turning back the bush. In one modification, the comb is hinged to the edge of a longitudinal slot in the beam ; in another the comb has at each end a journal 33, Fig. 13 having a pin 34. The comb 21 may be placed in brackets 36, Fig. 14 having arms 37 clamped to a bearing block of the beam, the threads being clamped in the beam by a clamping bar 39. A three cornered or a hinged clamping bar may be used.

Title: Automatic or semi-automatic telephone systems with party lines
IPC: H04Q3/58
Filed: 1940-04-19
Abstract: 544,736. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. April 19, 1940, No. 7094. Convention date, April 24, 1939. [Class 40 (iv)] A 10-party " house satellite or switching- centre is provided with a switch SS of sequenceswitch type for connecting any party individually to the common exchange line, the switch being controlled from the exchange by impulses over the loop so that no local current source is required. The parties are allotted individual outlets in the final selector banks, and'on a call to the satellite, a switch SM attached to the common line steps concurrently with the switch SS to find the selected outlet. On a call from the satellite, the switch SM serves to select the calling party's individual meter. Call from the satellite.-In the normal position of SS the common line 'is connected through a rectifier SR to all the party lines in parallel, so that when a call is initiated line relay A energizes followed by G, B, BR, R, C. Relay B reverses the line connections to energize the switch magnet SS which is bridged across the line through an oppositely-directed rectifier RR in normal position and through the rectifier SR in off-normal positions, and grounds the common c wire associated with the final selector outlets. Relay C puts impulse relay I under the control of interrupter INT to send reversal impulses over the line to step SS, the switch SM being stepped in synchronism. Offnormal relay D disconnects G, BR, but B holds, and relay A is now connected to the b wire instead of to the a wire of the common line which is extended through the opposed rectifier RR to the party lines in turn as SS rotates. Relay A therefore responds when the calling line is reached and disconnects C to stop impulsing, whereupon E pulls up and starts a finder PS hunting for the common line which is now extended to line relay S. Cut-off relay CO energizes in the test circuit, disconnects B and re-operates G to complete the forward loop, over which dialled impulses are repeated by S. The relapse of S when the calling party hangs up releases the switch train, whereupon CO, E fall back and C re-operates to send restoring impulses to SS over the common line and to SM. When both switches are normal, A energizes 'in series with SS and disconnects C, R and itself. Call to the satellite.-When a final selector is set on an outlet corresponding to a party line, relay F energizes over the common c wire and connects up FR, G. Impulses are sent as described above to step SS, SM in synchronism, except that B falls back with G, BR on the operation of D, and A is connected to wiper sma so that it pulls up when SM reaches the selected outlet. Impulsing therefore stops, and E switches through, ringing current being applied from a previous stage in the connection. Relay F falls back when the final selector releases, and the restoring operations take place as described above.

Title: Multiphase signal generator
IPC: G08G1/08
Filed: 1973-02-13
Abstract: 1412065 Control system; road traffic signals SOC JATEC 13 Feb 1973 [28 Feb 1972] 7098/73 Headings G4H and G4Q Control apparatus comprises means for supplying to each of a number of output terminals a respective control signal during a corresponding operating period S1-S15, the order of succession of the periods being predetermined and the length of the periods being independently adjustable. Pulses IH (64 to a cycle) from a clock OH pass to a frequency divider DF (six flip-flops) whose outputs B1-B6 are fed to an AND-gate decoder DC; the outputs IC1-IC15 from DC are fed to a stepping switch CA. CA outputs sequential pulse signals SP1-SP15 to an output decoder DS and to a selection decoder DR, both comprising OR-gates. The outputs V1-V3, J1-J3, R1-R3 are used to trigger power switches CS (e.g. triacs) to provide the required control signals; the outputs SS1-SS8 from DR are fed to respective branches of a control circuit CC each containing a manually adjustable impedance CC1-CCp and each connected to OH. The clock comprises an oscillator circuit (Fig. 2, not shown) with a unijunction transistor or 4-layer diode, and selection of a particular branch switches a particular impedance into the circuit so as to select the frequency of oscillation and thus control the repetition rate of pulses fed to DF: thus the values set in CC determine the duration of the operating period. The embodiment described (Fig. 6) relates to the control of sets F1-F3 of traffic lights (V1, J1,R1 veing GREEN, AMBER, RED signals for set 1), with the following relationship between colours and operating periods for set F1: Green S5 and S6; Amber S4, S6 (flashing) and S7; Red S1-S4 and S8-S15. Set F2 and Set F3 have a similar relationship, phase displaced 5 and 10 "S" units respectively from Set F1. This embodiment also provides for the shortening of any GREEN period when there is no vehicle approaching the corresponding set of traffic lights, by means of a fast (100 Hz) clock OHR controlled by bi-stable, time-delay and reset circuits FT, T, RAZ. When no signal appears at the output of an OR-gate 606, a reset signal is removed from RAZ, whereupon T energizes FT to start OHR after a manually settable time-delay. Signals from vehicle detectors L1-L3 are fed with GREEN signals V1-V3 to AND gates 608-612, thence to gate 606. A NOR-gate 614 ensures that OHR is stopped at the end of a GREEN period, and signals J1-J3 ensure that T is reset outside these periods (the time delay being greater than the duration of an AMBER or RED period). Detailed description is provided of CA, CC, OH and RAZ, T, FT, OHR (Figs. 2, 5, 7). It is stated that the apparatus may be used to control illuminated publicity special effects, automatic telephone reply systems or the driving of machines having several functions operating cyclically.
