Patent GB-892081-A (GB)
Title: Improvements in labelling machine
IPC: B65C9/22
Filed: 1960-09-16
Abstract: <PICT:0892081/III/1> <PICT:0892081/III/2> In a labelling machine (see Group XV), the labels are received on a rotary suction drum 24, Fig. 6, to cover grooves 38 spaced and extending in the peripheral direction of the drum.  A feeler 26 is urged by a spring against the periphery of the drum and the arrangement is such that in the absence of a label covering a groove 38, the feeler 26 drops into the groove and a contact 29 closes the energizing circuit 30 of a swing-off magnet 31 so that the glue-applying roller 25 is swung off the drum 24 against the action of a spring 49.  As soon as the feeler 26 passes the groove 38, the glue applying roller 25 is again swung on to the periphery of the drum.  A bell or other warning signal may be included in the energizing circuit.  The gluing roller 151, Fig. 17, which runs in contact with the glue applying roller 25 is mounted in a glue bath 175 in such a manner as to form part of its side boundary wall, sealing strips being provided on the vertical edges of the bath 175 and engaging the roller 151.  A protective tube 173 prevents passage of glue to the bearing 172 of the driving shaft 171 and a helical strip 183 serves to expel any glue penetrating the gap between the roller 151 and the tube 173.

Abstract: 741,874. Impulse transmitters. SIEMENS & HALSKE AKT.-GES. Dec. 19, 1952 [Dec. 21, 1951], No. 32305/52. Class 40 (4). [Also in Group XL (b)] A teleprinter includes a digit storage device arranged to be selectively adjusted by the selector bars operated by the digit keys of the teleprinter and to control the transmission of current impulses which serve when the teleprinter is connected in an automatic exchange system to operate the selector apparatus in the exchange. The operation of a digit key of the teleprinter moves the bars 15 so that a set of notches is aligned opposite one of ten levers 4/1 ... 4/10. At the same time, a bar 1 as raised so that a projection 11 releases a shaft 2 for rotation and a projection 12 is moved clear of a projection 32 on a drum 3 which is set into rotation. A projection 36 allows the selected lever 4/1 ... 4/10 to rock so that its end arrests the drum 3 after the appropriate rotation. The shaft 33 of the drum carries a ratchet wheel 34, and an extension 13 on the bar 1 permits a retaining pawl 6 to move inwards when a pin 61 is released, at a position corresponding to the maximum rotation of the drum 3, from a projection 51 on a lever 5 raised by the rounded portion of a cam 22 on the shaft 2. During each revolution of the shaft 2, a lever 7 rocked upwardly by a flat on the cam 22 actuates a pawl 71 to rotate the ratchet wheel 34 one step towards its initial position. A cam 23 on the shaft 2 closes contacts 24 to send a selecting impulse, the number of impulses being determined by the number of steps of the ratchet wheel and drum to reach the initial position in which the projection 12 falls behind the projection 32 and the projection 11 on the bar 1 arrests the rotation of the shaft 2. At the same time the downward movement of the extension 13 presses back the pawl 6 which is latched in the position shown when the projection 51 engages the pin 61 due to the engagement of the finger on lever 5 with the flat on the cam 22.

Title: Hydraulic shock absorbers for motor vehicles and the like
IPC: F16F9/20
Filed: 1931-11-25
Abstract: 388,506. Road-vehicle suspension; hydraulic shock - absorbers. LANDEWEER, K., 74, Biltstraat, Utrecht, Holland. Nov. 25, 1931, No. 32735. Convention date, Jan. 21. [Classes 108 (ii) and 108 (iii).] With the object of preventing lateral tilting of the body and frame of a vehicle relatively to the axles, fluid shock absorbers of the oneway type are rendered double acting when the vehicle is tilted or is subjected to forces tending to tilt it. In the construction shown in Fig. 1, cylinders 1, 2, mounted on opposite sides of the vehicle are each provided with pistons 3, 4 connected to opposite ends of the axle and each having a small leakage orifice 7, 8. Opposite ends of the cylinders are connected by pipes 9, 10 with one-way valves 11, 12, which allow upward movements of the pistons but check downward or rebound movements. The connections 9, 10 are further provided with cocks 13, 14 which are normally open but may be closed by rods 17, 18 when a pendulum 28 swings to one side or the other under the action of centrifugal or other forces, so that one of the shock absorbers opposes downward movements of the frame. In a modification an inverted pendulum held centrally by a spring operates the cocks 13, 14 through electric relays In a further modification each cock is operated by linkwork connecting it to the piston-rod on the opposite side of the vehicle. In the modification shown in Figs. 4 and 5, two shock absorbers each constructed as shown in Fig. 5, are arranged on opposite sides of the vehicle and are cross connected by pipes 83, 84. In each case a rocking lever 69, 70, actuated by an arm 57, 58, connected to the axle, operates two pistons 63, 64, having large one-way valves 65, 66, which allow relatively free upward movement. Downward movement of the pistons is retarded by throttling devices consisting of grooved or hollow stems 72, 73. The interior of the hollow stem 73 communicates with its cylinder through throttling orifices 75 which may be more or less closed by a movable stem on a piston 79, the lower end of which is subjected to pressure transmitted from a cylinder on the opposite side of the vehicle. A spring 82 opposes the fluid pressure. As long as the frame and axle remain parallel to one another upward and downward movements on each side of a vehicle are restrained by forces which depend upon leakage through the groove 72 or the port 75 and also upon the spring-controlled relief valves 65, 66 ; but when the frame tends to tilt, the shock absorber on the side which rises increases the braking effect which counteracts the tendency of the opposite side of the vehicle to drop. In a modification, the resistance of the relief valves is also controlled by the pressure in the connecting pipes 83, 84.
