Title: Contact breaker assemblies for use in ignition distributors
IPC: F02P7/063
Filed: 1972-01-15
Abstract: 1409261 Mechanical interrupters LUCAS ELECTRICAL CO Ltd 29 Dec 1972 [15 Jan 1972] 2025/72 Heading H1N In a contact-breaker assembly for an ignition system distributer, Fig. 1, a leaf-spring 19 attached at one end to a movable contact 14 and urging it towards a fixed contact 13 acts as an electrical connection and has a clip 23, Fig. 5, formed at its other end which is anchored by an insulating abutment member 21 being attached to a tongue 22 upstanding from an angle-plate 11. The clip serves as an attachment point for conductive leads terminated with various forms of terminal members having interlocking means to resist transverse movement relative to the clip after being slid in from the open end, withdrawal in the longitudinal direction being prevented by the closed end of the clip and the abutment member when assembled. Adjacent one edge of a terminal member 25, Fig. 2, a deformable tag 27 grips the sheath of a conductive lead extending generally parallel to said edge, the core being welded to the member, whilst adjacent the opposite edge a cranked portion 28 is formed with the optional provision of a similar cranked portion adjacent the one edge (Fig. 4, not shown). Intermediate the two edges is a centrally disposed dimpled projection 26 which can be gripped by the clip and which is of such a depth that a second terminal member 29 (Fig. 7, not shown), being substantially flat with an aperture 29a, can be assembled back-to-back in manner shown in Fig. 2. Initial attachment of two conductive leads can be by means of a double-edged terninal member 31, Fig. 6, which has a similar dimple projection 32 and which permits a third conductive lead to be back-connected as described or which provides means for replacing either of the two leads by cutting off at the cranked portion of the terminal member 31 adjacent the lead attachment point and using a part 29 as a replacement or another part 35 (Fig. 9, not shown) which has an open-ended slot for engagement with the dimple projection and an extension 37 for insertion in the channel of abutment member 21 and which can be inserted without dismantling the existing assembly.

Filed: 1929-01-21
Abstract: 304,607. Geesink, M. Jan. 20, 1928, (Convention date]. Drawings to Specification. Seats &c., arrangement &c. of.-Vehicles, particularly for ambulance service, comprise a. frame for a litter or seat which is rockable on one or more horizontal axes under the influence of one or more weights in such a manner that on changes of direction or of speed of the vehicle the litter &c. moves to such a position as to tend to prevent relative movement between the occupant and the litter &c. In one form the litter frame is supported on a longitudinal axis and is provided with a pendant weight the force on which, if the vehicle changes its direction, causes the litter frame to incline in the appropriate manner. Spring suspensions are provided in addition. The frame may be provided with two parallel axes so arranged in bearings that on tilting to one side one of the axes rises in its bearings. The weight may be arranged above the frame and so connected to it as to communicate to it the appropriate movements. The movements of the weights may be restrained by spring or other brake means, while the axes may be also arranged transversely of the vehicle.

Title: A control for an electro-magnetic clutch and brake
Inventor: LEESON JAMES L
IPC: H02P29/00
Filed: 1960-01-20
Abstract: 893,379. Clutch-brake combinations and control. WARNER ELECTRIC BRAKE & CLUTCH CO. Jan. 20, 1960, No. 2147/60. Class 80 (2). A control for an electromagnetic clutch 13 and brake 14 which respectively drive and stop for equal periods an output shaft 12, comprises a square-wave impulse generator 38, the impulses (Fig. 3, not shown) from which are converted by a differentiating network 30 to a first alternating signal (Fig. 4, not shown) which is applied to an amplifier and phase inverter 33, to produce two second alternating signals (Figs. 5 and 6, not shown) one in phase and the other out of phase with the first signal, the positive half of each of the second signals are amplified by valves 36, 37, or transistors, and applied to the clutch and brake windings 10, 11 respectively. The control grids 67 of the valves 36, 37 are biased negatively from a source 72 so that the negative bias is only overcome by the positive half of the signals. The energizing voltages applied to the clutch and brake windings rise to an initial peak, above the rated voltages of the clutch and brake to overcome hysteresis and eddy current effects, and then decrease exponentially to approximately 45% of the rated voltages. The running and stopping periods may be adjusted by adjusting the frequency of the impulse generator.  The electromagnetic clutch 13 comprises a stationary magnet 10 with an annular U-shaped core 21 which surrounds part of the pole rings 17 to provide a radial air gap. The pole rings are radially spaced by a ring of non-magnetic material 18 and are fast with a continuouslydriven input shaft 15. An armature 20 is splined on the output shaft 12. Figs. 7-10 (not shown) are graphs of the control grid voltages and the clutch and brake energizing voltages against time and Fig. 11 (not shown) shows oscilloscope traces of the control impulse and the speed of the output shaft.

Abstract: 440,758. Producing knopped woollen yarns. MIDDLEMOST, H. E., Clough House Mills, Birkby, Huddersfield. Jan. 23,1935, No. 2187. [Classes 120 (i) and 120 (iii)] In producing knopped or flaked woollen yarns, slivers or the like b, Fig. 1, are fed at a determined rate to revolving helical cutting blades f, g acting in co-operation with a fixed cutting blade d, the shorn-off flakes being guided down on to a travelling carded web n as it is passing to the dividing rollers o. The blades f, g may be arranged to act upon alternate slivers while guide plates hare provided to keep the flakes in their correct paths. When dealing with slivers of fibrous material a pivoted member i, Fig. 2, having pins or teeth i<1> is provided between each pair of guide plates h the member i serving as the revolving blade approaches the blade d to engage the sliver, the flake then being carried round by the member i which pivots outwardly and deposits the flake clear of the helical blades on to the pins of a spiked roller j about which, and a roller k, passes a lattice m. If the flakes are made from non-fibrous material the members i, m may be dispensed with and fixed guide plates disposed beneath the revolving guides h. Alternatively the lattice m may be retained and provided with spaced longitudinal ribs co-operating with the guides h.

Abstract: 335,143. Jacobsen, N. A. Jan. 25, 1929. [Convention date]. Guiding and stretching mechanism.-The web on the wire of a paper-making machine is divided into two or more parallel strips by means, such as a jet of water, actuated when a portion of the web torn off at the couch cylinder accumulates on and tilts a pivoted plate &c., the web being thus divided into parallel strips thereby stopping the tear when it reaches a division line and preventing complete severance of the web. The torn part of the web, removed from the wire by an auxiliary cylinder 6, accumulates on, and weighs down the hinged plate 7, and actuates a valve 9, to which it is connected by a flexible wire &c. 8, thus causing the jet of water to impact on the web. The jet is then moved towards the edge which has been torn and severs the torn portion from the main sheet. The jet may be arranged centrally or nearer the side which has the greater tendency to tear, or two or more jets may be employed, and operated simultaneously or selectively. An electric or other relay may actuate the jet.
