Title: Improvements in signalling apparatus for motor driven and other road vehicles
IPC: B60Q1/34
Filed: 1922-04-18
Abstract: 195,281. Longson, J., and Vickers, J. April 18, 1922. Road-traffic signals on vehicles.-In a turning signal for vehicles, a lamp, pointer, &c. rotatable about a vertical axis to indicate turning to right or left, is also tiltable about a transverse horizontal axis to indicate intention to go forward. In conjunction with the above, pointers normally housed in casings from which they can be selectively extended may be provided at the sides of the vehicle. A single operating device for controlling the points &c. is described. The lamp x and pointer y are mounted on a shaft which is normally vertical and has a bevel wheel connection within a casing h with a normally horizontal shaft projecting rearwardly from the casing. This shaft end is embraced bv slotted cheeks v on an operating rod t, a transverse pin u passing through the slots. The casing h is pivoted at l and is normally held with the pointer axis vertical by a spring m. By pushing the rod t forward, the lamp &c. is tilted to the position shown, to indicate intended forward movement. By rotating the rod t, members x, y are rotated to the right or left, to indicate turning. Rod t is normally retracted by a spring 7, and its operating knob 4 carries a projection 5 cooperating with a recess, so that rod t can only be rotated when the casing h &c. is upright, and casing &c. can be. tilted only when the pointer y &c. is pointing forward. Rod t slides through and is adapted to rotate a toothed wheel 8 engaging a transverse rack connected to rods 14. Rods 14 have pin and slot connection 16, 17 with levers 18, adapted to project one or other of two laterally placed pointers from its casing 15 according to the direction of rotation of rod t. Slots 16 provide for lost motion so that only one pointer is affected. The pointers are normally retracted by springs 25, which also normally hold the rack in the central position. The pointers may carry lamps 22, the circuits of which may be closed continuously, or only when the corresponding pointer is projected from its casing. When this lateral signalling arrangement is omitted, the forward signalling arrangement is normally held in central position by a spring 31 engaging a cam member 29 mounted on the rod t, Fig. 7.

Title: Sequential macbines and logic elements for such machines
IPC: G05B19/07
Filed: 1973-01-26
Abstract: 1373064 Bi-stable and gating circuits NATIONAL RESEARCH DEVELOPMENT CORP 26 Jan 1973 [10 March 1972] 11325/72 Heading H3P [Also in Division G3] A sequence control system is set up from a state graph, Fig. 1, which shows the logic steps involved in detecting a sequence of signals a, b, c from four signals a, b, c, d. The nodes N1, N2, N3, N4 each represent a state. Initially only node N1 is set and signals b, c, d cause no change of state, which is denoted by a loop, whereas a signal a, by the arrowed link, causes node N2 to set, node N1 being re-set. The subsequent response of the nodes, indicated by the arrangement of loops and links causes the detection of the desired sequence which terminates when node N4 is set through link c. A nodal element, Fig. 2, comprises bi-stable devices 10, 12 formed by cross-connected NAND-gates. The element is set by an input signal on any one of terminals X1-X3, through a NOR gate 14, to the device 10. When the input signal ceases a NAND gate 16 opens to set the device 12, reset the device 10 and make available a signal at a terminal P for control of other nodal elements. The setting of the bistable 12 opens AND-gates 20-23 so that a stimulus signal on any one of terminals S1-S4 is passed to the corresponding output terminal Y1-Y4. An AND-gate 24 is connected to the reset input of the bi-stable device 12 for control by signals from the P-terminals of other nodal elements on input terminals R1-R3. In an arrangement of interconnected nodal elements the signals X1-X3 are derived from the stimulus signals S1-S4 by a set of recognition gates (Fig. 3). Alternative embodiments of nodal elements are described for use with positive or negative logic interconnections between nodes.

Title: Improvements in or relating to windows
IPC: E05D7/084
Filed: 1938-04-13
Abstract: 496,917. Pivots. PERSSON, E. S. April 13, 1938, Nos. 11357 and 11358. Convention dates, Aug. 30, 1937 and Oct. 6, 1937. [Class 65 (ii)] A pivot for a window sash mounted on a horizontal axis by means of a pivot pin substantially in line with the centre of gravity of the sash is provided with means whereby the pivot pin is moved away from the plane of the sash and downwards as the window is opened ; the rotation of the window is preferably resisted by frictional means. In the form shown in Figs. 4 and 5, the pivot pin 41 fixed to the sash 1 carries a notched sector member 42 of tapering section which works on pins 36 on the frame 2 to displace the pin 41 laterally during rotation ; the sector 42 fits between plates 31, 34 on the frame, and the weight of the sash wedges it between these plates, which are adjustable to and from one another, to resist the movement of the window. In the closed position a fixed pin 35 engages a notch in the sector 42 to locate the latter, and when the sector runs off the pins 36 in opening the window it rotates about a pin 37. In a modification, the sector 42 is not tapered in section and runs freely on the pins 36, the pivot pin 41 running on the edge of the plate 31. In another modification, Fig. 8, the pivot pin 64 has teeth on part of its periphery engaging an inclined rack 62 on the frame, the rack ending in a concave portion 63 in which the pin can rotate without translation during the last part of the opening movement. The movement is controlled by a contractible brakeband 67 engaging a cylindrical part of the pin 64 and anchored by a pin 69 ; in the form shown the brake-band moves on the pin 69 during opening of the window, but in a modification the teeth 62 are arranged on an arc concentric with the pin 69. In a further modification, the pivot pin carries two discs with teeth running along a rack in a similar way to that shown in Fig. 8, the ends of the pin being guided in inclined grooves in the member on the window frame : the frame member has a guide rib engaging between the lower parts of the two discs, and carries between the upper parts of the discs a rib of wedge-shaped crosssection which can be pressed down between the discs, for example by a screw adjustment, to produce frictional resistance to motion.
