Title: Apparatus and method for winding flexible material for twistless  payout through a straight radial opening
IPC: B65H54/28
Filed: 1973-07-05
Abstract: 1431926 Apparatus for winding packages with radial openings WINDINGS Inc 5 July 1973 32025/73 Heading D1J An apparatus of the kind in which a yarn is traversed onto a rotating spindle 2 by a guide element 6 that is pivotally mounted to allow for increasing package diameter, is characterized in that the yarn is wound onto the package in figure-8 windings, there being means for causing successively formed crossover of alternate layers to be angularly spaced around the package in opposite circumferential directions and for the total angular distance from the first cross-over to the last cross-over thereof in the direction of progression of the cross-overs around the package to be less than 360‹ so as to define a radial opening 10 in the package as distinct from the curved opening 8 that would otherwise occur due to the swing of the guide element 6 about its pivotal axis. Thus, for example, the cross overs may extend around 345‹, so that a gap of 15‹ is left in which there are no cross-overs and therefore there is a hole. The holes in successive layers thus formed overlie each other to form the radial opening. In one embodiment the relative speed of traverse and rotation is progressively changed during the build-up of the package so as to cause said radial opening to be formed. In a second embodiment means are provided for producing a slight angular shift of that part of the spindle element 2 on which the material is wound with respect to the guide element 6 after a predetermined number of layers have been wound onto the package. To this end there may be a mandrel on the shaft 2, the package being wound on the mandrel. Friction means normally prevents the mandrel from rotating relatively to the shaft 2 but when slight angular shift is to be effected the mandrel is rotated on the shaft 2 against the resistance of the friction means.

Title: Improvements in and relating to lamp arms and lamp brackets for photographic contactprinting machines
IPC: G03B27/16
Filed: 1946-10-31
Abstract: 621,763. Photographic contact printing. HALDEN & CO., Ltd., J., and HILTON, P. Oct. 31, 1946, No. 32308. [Class 98 (ii)] A machine of the kind in which lamps are moved automatically to and fro inside a glass case, on the outside of which the tracing and sensitive paper pass, is provided with a lamp arm which is mounted at one end on a reciprocating device and is at the other end mounted on a rod passing through, or secured to, two parallel arms of a lamp bracket, the rod being slidable in the bracket arms, or the lamp arm being slidable on the rod, so that at each end of the travel of the lamp arm the bracket is left in its end position till the lamp arm has travelled in the reverse direction to the other end of the bracket, and thus lamps attached to the lamp bracket are caused to dwell for a short period at each end of their path of travel and so provide full exposure at the edges of the sensitive sheet. As shown, the lamp arm 5 is reciprocated in the usual way by an archimedean spiral 7, and as it does so slides the rod 4 in the holes in the short arms 3 of the lamp bracket and pushes the bracket, to which a lamp is attached at the side 2, buffer springs 6 absorbing the shock. If desired, the lamp arm 5 may slide on the rod 6 and the latter may be fixed to the side arms 2. Instead of the archimedean spiral 7, other means of obtaining reciprocating movement of the lamp arm 5 may be used, such as its attachment to an endless driven chain passing over two sprocketwheels.

Title: Improvements in and relating to means for driving auxiliary apparatus mounted on motor vehicles
IPC: B60K25/00
Filed: 1930-10-28
Abstract: 366,499. Driving auxiliary apparatus on motor vehicles. WERF CONRAD NAAMLOOZE VENNOOTSCHAP, (formerly NAAMLOOZE VENNOOTSCHAP SCHEEPSWERF EN WERKTUIGENFABRIEK WERF CONRAD), Haarlem, Holland. Oct. 28, 1.930, No. 32360. Convention date, July 10. Addition to 366,119. [Class 79 (ii).] In means for driving auxiliary apparatus on motor vehicles wherein, after the vehicle has been jacked-up, the driven road wheels are raised into peripheral engagement with and serve to drive coplanar friction wheels, as set forth in the parent Specification, the suspension springs of the driven axle are utilized to press the road wheels elastically into engagement with the friction wheels. In the arrangement shown in Fig. 1, the driven axle 7, normally mounted at one end of springs 6, is detached therefrom and at each end connected to a link 9 pivoted to the longer arm of a lever 10 carried by an eye-bolt 12 and temporarily connected to the spring 6 by a link 13 and clamp 14. The wheels 15 are drawn up into engagement with the friction wheels 16 by adjustment of the eye-bolt 12 in the vehicle frame 11. A similar transposition may be effected when the axle is attached to the centres of ordinary end-shackled suspension springs. Alternatively, instead of disconnecting the axle, the shackle at one end 19, Fig. 4, may be disconnected and the spring and axle drawn up by the eye-bolt 12 through the medium of a floating lever 22 and a pair of links 20, 21.

Title: Improvements in electrical circuit control devices
IPC: G05F1/00
Filed: 1933-11-21
Abstract: 429,177. Electromagnetic switches. WESTON ELECTRICAL INSTRUMENT CORPORATION, 614, Frelinghuysen Avenue, Newark, New Jersey, U.S.A.-(Assignees of Lamb, A. H.) Nov. 21, 1933, No. 32421. Convention date, Sept. 8. [Class 38 (v)] An electric circuitcontrol device involving an instrument - type relay for controlling an electric circuit or circuits in accordance with variations of a factor measured by the instrument comprises an in. strument having a pair of relatively-movable elements carrying contacts for closing a motor circuit, which motor opens the said contacts also actuates a switch for completing an energizing circuit for said motor independently of said instrument contacts and also opens and closes a load circuit switch. As shown in Fig. 1 the instrumenttype relay which may be of the type described in Specification 432,100, has a moving coil 1 carrying a pointer 2 provided with a softiron armature 3. On approaching either of its limiting positions it comes within the influence of a magnetic contact 4 or 4<1>. The relay contacts are then closed rapidly as the armature is drawn towards one of the magnetic contacts. The closure of the contacts completes the circuit of a motor 5 which on rotation causes a cam 13 on its shaft 10 to operate contacts 14 and complete a maintaining circuit for the motor and also causes one or other of two pusher arms 11, 11<1> to push the contact arm 2 away from the contact it has engaged so removing the armature 3 from the influence of the contact 4 or 4<1>. The motor shaft 10 also carries a cam 15 to close contacts 16 in a controlled or load circuit 17, which may include regulating elements for counteracting the changes which resulted in the measured variation of the controlling factor and may be employed to actuate a visual or audible signal. At the end of a revolution the motor maintaining circuit is automatically broken at contacts 14. In a modification shown in Figs. 2 and 4 where the instrument has a wide angle scale, magnetic contacts 4<a> are supported on adjustable pivoted arms 19 below the pointer 2 which on approaching said magnetic contacts is drawn downwardly into engagement, the pointer 2 being flattened at 2<1> to permit its flexure during the contactmaking movement. After contact has been established the motor circuit is completed, an eccentric 27 is rotated allowing the arms 19 to be lowered to the dotted position by a spring 25, thus breaking the instrument contact as the arm 2 is prevented from following the magnet 4a by its end engaging the fixed scale 18. The rotation of the shaft 27 actuates a maintaining switch in the motor circuit in the manner already described and also a tilting mercury switch 16<1> in the controlled or load circuit. A similar arrangement may be employed with a vertical scale instrument. In a further modified arrangement the load circuit is arranged to be completed only after the pointer contact has been brought into engagement with one of the relatively fixed instrument contacts a predetermined number of times.
