Abstract: 516,779. Making boxes &c. STOKES & SMITH CO. July 7, 1938, No. 20122. Convention date, July 7, 1937. [Class 18] In forming or wrapping boxes, box covers, containers &c. by applying sheet material such as wrappers, tabs, labels &c. to box &c. members, the assemblage A, Fig. 11, which is to be formed into a box &c. is brought by a conveyer C to the neighbourhood of a reciprocating former block F where it is gripped between arms 77 and shoes 81a and thereby moved into the path of the former block which then moves, carrying with it the assembly to various stations at which the folding and securing is effected. The assemblage may be placed manually or mechanically between the arms 77. The arms 77 and shoes 81a, which are adjustable in various sizes of bore. &c. and which grip by suction, are carried on tubes 74, Fig. 10, to which vacuum is led through tubes '79, and are reciprocated from a support 76 itself reciprocated through the sequence of elements 84, 86, 87.55, 64, 65, and a cam groove 66 on cam 59 carried by shaft 2. The assembly may be moved from the conveyer with the arms 77 by a suction arm 35, Fig. 7, which is reciprocated by rods 61, and oscillated about an axis 38 by a roller 41 engaging a groove in a vertically reciprocated member 43. Correct alignment of the elements of the assembly is effected by a stop 29, Fig. 8, and an arm 32 oscillated from a cam follower 72. The suction is controlled by a valve V, Figs. 5 and 6, the piston 88 of which has two stationary positions, in one of which suction is led to arm 35, and in the other of which suction is led to the elements 77, 81a. The various parts are actuated from a main shaft 2. Fig. 1, driven through clutch 3, 4 which is engaged so long as a pedal 5 is depressed but disconnected at the end of a stroke when the pedal is released by engagement of a pin 7 with a cam 8 on shaft 2 which actuates a bell-crank 9 through pin 7 to disengage the clutch. The vertical reciprocation of the former block is effected by levers 10, 11, cam followers 12, 13 and grooves 14, 15 in cam 1. The various tools for applying the sheets &c. are carried by tool slides 19 on table 20 which are actuated through the sequence 21 - 28, Fig. 1. Suction arm 35 and aligning arm 32 are actuated through a member 43, Fig. 2, reciprocated vertically under the control of a cam 58, Fig. 2, cam follower 57, Fig. 10, and the sequence 54, 53, while the carriage 36 of suction arm 35 is actuated through link 61 and levers 63, 64 actuated by cam 59 on shaft 2.

Abstract: 1280278 Reducing cross-talk in multiplex communication systems; multiplex pulse signalling INTERNATIONAL STANDARD ELECTRIC CORP 19 April 1971 [26 Jan 1970] 20169/71 Headings H4K and H4L A time division multiplex communication system with GO and RETURN highways reduces cross-talk between channels by terminat - ing each highway at one end with an amplifier showing low impedance to the highway and by terminating the other end of each highway with its characteristic impedance. As shown in Fig. 4 subscribers T are connected from one side of a hybrid G to a GO highway by means of gates S 1 to Sk. Highway pulses are passed on over a low impedance amplifier V terminating one end of the highway. For a GO highway V may be a transistor in common base configuration. For a RETURN highway V may be a transistor in emitter-follower configuration. The ends of the highways remote from amplifiers V are terminated with the characteristic impedance which absorbs any reflections from low impedance termination of V. Between time channel switching periods the ends of the highways connected to amplifiers V may be switched to the characteristic impedance as a termination in order to promote discharge of the highway.

Title: Electron gun
IPC: H01J29/48
Filed: 1958-06-25
Abstract: 864,272. Electron beam apparatus. RADIO CORPORATION OF AMERICA. June 25, 1958 [July 22, 1957], No; 20454/58. Class 39(1). An electron gun in a cathode-ray tube comprises an annular cathode 22 coaxial with the tube and having an electron-emissive inner surface, a probe electrode 46 centrally disposed with respect to the cathode and having an end portion 48 shaped to direct electrons in the direction of the tube axis and toward the target electrode and a plurality of annular electrodes 32, 34, 37, 39 coaxially arranged between the probe electrode and the cathode to provide an accelerating field therebetween. As shown, during tube operation the control grids 32, 34 are connected together and biased negatively with respect to the cathode while the accelerating grids 37, 39 are at the same or different positive potentials, the probe electrode being at cathode potential or slightly negative thereto so that electrons from the cathode are focussed and accelerated first radially and then axially on to an aperture 54 in object electrode 50. Electrons passing through aperture 54 are focussed and accelerated by electrodes 56, 64, 66, 68 to converge to a small spot on the fluorescent screen, the spot-size being practically independent of beam current. Examples of electrode dimensions and operating potentials are given. The indirectly-heated cathode 22 is formed as an annular ring having a U-shaped cross-section and is fixed to a mounting ring 24 by a plurality of metal straps 26 each having one end fixed to the cathode and the other to ring 24 so that any expansion of the cathode merely rotates it about its axis without altering its axial position. The ring 24 and the remaining electrodes are supported by glass rods 30. The field configuration in the electron gun is such that only those electrons emitted perpendicularly from the cathode surface are able to pass through aperture 54 thus eliminating fringe electrons which would normally result in distortion of the beam spot. Any positive ions generated by the beam which pass through aperture 54 are attracted by the probe electrode and do not bombard the cathode. Instead of operating electrode 39 at a potential higher than that of electrode 37 in order to obtain the desired field configuration, the cylindrical wall portion 42 may be made thicker than wall portion 40 or may be of smaller diameter, the electrodes then being operated at the same potential.

Abstract: 742,581. Chucks and sockets. SAUNT, Ltd. J. A. Nov. 16, 1953 [Aug. 15, 1952], No. 20522/52. Class 83 (3). A self-aligning tool-holder comprises an assembly of three members 3, 8, 16 in general axial alignment, member 16 carrying a drill chuck 19 or a socket for a drill, reamer, tap, &c. and member 3 being fixed to driving-shaft 4. Member 8 has two pairs of pins 9, 13 on diameters at right-angles to each other, and engaging slots 11, 14 respectively, in members 3, 16. The members are contained in a housing 2 screwed to a member 3 and locked thereto by disc 6 and screws 7. Rollers 23, 24 in cages having straight grooves, are provided between the members, and a ball-race 26 between member 16 and the bottom of the housing. A chuck &c. supporting spindle 17 extends with clearance through a bore 18 in the end of the housing and carries a cup-shaped ring 27 capable of engaging the outer periphery of housing 2 to hold spindle 17 in alignment with shaft 4. The ring may be held in this position by a spring-pressed ball 29 but is movable downwards against a spring ring 32 to allow the tool to float laterally. In use in a drilling- machine, with parts 4, 17 in axial alignment, work having a pilot-hole &c. is positioned in approximate alignment with the drill. The ring 27 is then moved out of contact with housing 2 to allow the drill to float and align itself accurately with the axis of the hole. When used horizontally to hold a drill &c. in a lathe, a clamp 33 on the housing supports the drill through a spring-pressed plunger 34. In a modification (Fig. 3, not shown), spindle 17 has a socket to hold the tapered shank of a tool, and extends both out of the housing and also upwardly in the housing, passing through member 8 and terminating in a domed recess formed in member 3. Slots in the side of the dome allow access for a drift to remove the drill &c., the slots being closable by pivoted covers which carry a member for supporting the upward extension of spindle 17 when the drift is used.

Filed: 1945-08-10
Abstract: 597,123. Washing granular materials. AUTOMATIC COAL CLEANING CO., Ltd., and WALLACE, W. M. Aug. 10, 1945, No. 20565. [Class 82 (ii)] In a washer box or jig for coal and other materials, in which washing is carried out by means of the pulsatory action of water through a grid supporting a washing bed, a plurality of washing compartments is provided, each of which has its own individual governor controlled by the weight of material in its compartment and in turn controlling the pulsations. The governor is in the form of a piston actuated by the water under the washing bed, or is a float in the washing bed of the compartment; in the latter case the pulsations being controlled through the medium of an exhaust valve connected to the air chamber in which pulsations are produced. In the form shown, a series of washing compartments 3 ... 7 fitted with grid 8 through which water pulsates, is supplied with coal &c. to be washed, at 2. Separation into light and heavy layers 10, 12 occurs, these products travelling to the delivery end furnished with a governor 14. Each compartment is fitted with a governor 15 ... 19 ( see Fig. 2), each of which comprises a piston 26 in a cylinder 26a opening under the washing bed 8, which piston oscillates with an amplitude which increases with increasing weight of material on a grid 8 and in so doing, through the medium of a power drive 29, closes a valve 27, thus preventing escape of compressed air from a chamber 23 in which air pulsations are produced by means 22. This allows a maximum pulsatory effect. Reduction in the load on grid 8 reduces the amplitude of a piston 26 (since water now passes more readily through the bed of material) which partially opens a valve 27 allowing escape of air from chamber 23, thus reducing the pulsatory effect. The piston and cylinder 26a may be replaced by a float in the washing bed. Using the piston type of governor, other forms of regulation are (a) a pipe 28 is connected direct to the air supply pipe 21 to release air therefrom, or (b) the valve 27 is arranged between the pipes 20 and 21 and the regulation is carried out without loss of air by throttling the supply, in which case, when the stroke of the piston 26 is a maximum, the valve 27 is arranged to be fully open.
