Title: Imrpovements in shutters for signalling and like lamps
IPC: G08B5/38
Filed: 1938-12-06
Abstract: 579,039. Signalling by visible signals. BRITISH THOMSON-HOUSTON CO., Ltd., BOURNE, H. K., DAVIES, L. J., and RUFF, H. R. Dec. 6, 1938, No. 35586. [Class 118 (ii)] The shutter of a signalling lamp is operated pneumatically by a diaphragm or piston which transmits variations of air pressure to a piston attached to or forming part of the shutter, and the area of the diaphragm is considerably greater than that of the shutter piston so that the required movement of the shutter is obtained with a relatively small movement of the diaphragm. The source of light 1, which may be an electric discharge lamp, is surrounded by a shutter 2 that reciprocates in a housing 3. This housing terminates at its lower end in a portion 5 of greater diameter which contains a diaphragm or piston 4. The diaphragm may be operated by hand or mechanically, but preferably is connected to the armature 6 of a solenoid 7. Energization of the solenoid causes the diaphragm 4 to move downwards, and the resulting rarefaction of the air in the housing 5 opens the shutter 2. The solenoid may be energized by increasing 'the flow of current through the lamp 1 in the manner described in Specification 579,034. Two lamps may be arranged on opposite sides of the diaphragm so that both shutters can be actuated simultaneously.

Title: Acoustic Well Logging Apparatus and Method for Detecting Fractures
Inventor: LOREN JAY DENNIS
IPC: G01V1/44
Filed: 1968-07-26
Abstract: 1,184,880. Acoustic borehole-logging. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 26 July, 1968 [28 July, 1967], No. 35833/68. Heading H4D. Fractures in earth formations traversed by a borehole are detected by transmitting at least one acoustic pulse for every 2À5 cm. depth increment of a logging tool, deriving electrical waveforms that correspond to the amplitudeversus-time characteristics of the resulting received acoustic waves, generating from these waveforms control signals for controlling the amplitude of the electrical waveforms, and displaying the amplitude-controlled waveforms. In the Fig. 1 embodiment, acoustic waves travel by several paths between transmitter T and receiver R and interfere at the receiver. The receiver output (Fig. 2) for each pulse is transmitted uphole, where trigger generator 22 controls integrator 13 such that the waveform in interval t 1  to t 2 , containing first arrivals, is integrated to provide a voltage which is fed via an adjustable-time-constant circuit 14 and sample-and-hold circuit 15 to the control input of gain-controlled amplifier 16. The receiver output is fed via amplifier 16 to oscilloscope 17 to give a display (comprising a series of side-by-side oscillograms) related to depth of the logging tool. Circuits 13, 14, 15 provide delayed automatic gain control, giving an optimum display for recording by camera 31. In an alternative embodiment, transmitter T is disposed half-way between two receivers, the two receiver outputs are fed to a difference amplifier and the difference signal is fed to the circuits 13-16 of Fig. 1.

Title: Flow control means
Inventor: RAY WILLIAM ALTON
Filed: 1964-09-02
Abstract: 1,084,854. Fluid-pressure servomotor systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Sept. 2, 1964, No. 35924/64. Heading G3P. [Also in Division F2] In a gas control valve, the valve element is moved rapidly to a partially open position and then moved gradually to its fully open position. As shown, the valve comprises an inlet 10, outlet 12 and main valve 52 carried by diaphragm 54 and urged to a closed position by spring 80 and gas pressure communicated from the inlet to the chamber 62 above the diaphragm via passage 74 and nozzle 66. Upstream of the main valve is a pressure regulator comprising closure members 21, 22 carried by a stem 19 attached to diaphragms 24, 25, diaphragm 24 having a larger diameter flex circle than diaphragm 25. A spring (90) Fig. 2 (not shown) acting on lever 92 biases the closure members to an open position. The space between the diaphragms 24, 25 communicates with the outlet via passage 46 and restriction 49. When plug cock 14 is open and the main valve 52 is closed, the pressure in chambers 23, 78 rises to a value determined by spring (90) and valves 21, 22 are seated. On opening the main valve 52 by energizing solenoid 70 to cause flapper 67 to close nozzle 66 and open vent nozzle 68, the pressure in chambers 23, 78 falls so that valves 21, 22 partially open to restore the pressure level to its initial value. Gas being supplied to the burner via outlet 48 can now leak through restriction 49 to chamber 31 and act on diaphragms 24, 25 in a sense assisting spring (90). Valves 21, 22 thus move progressively to a fully open position and the regulated pressure level rises to the high-fire setting. The supply to solenoid 70 may incorporate a switch operated by a thermostat and a thermocouple heated by the pilot flame.

Title: Tube expander
IPC: B21D39/16
Filed: 1953-12-28
Abstract: 765,065. Tube expanders. AIRETOOL MANUFACTURING CO. Dec. 28, 1953, No. 35992/53. Class 83 (4). A tube expander having a plurality of tapered rollers radially movable in a cage by axial movement of a tapered mandrel therethrough, the axes of the rollers being inclined slightly to the axis of the cage and mandrel is characterized in that the mandrel is adapted to be rotated first in one direction so that it is drawn by and into the rollers to expand them and then, after locking the cage and mandrel against relative axial movement, to be rotated in the opposite direction so that the cage and mandrel are together fed, by rotation of the inclined rollers consequent upon the rotation of the mandrel, axially of the tube to effect the expansion of the tube along the rest of that part of its length to be expanded. In one embodiment, Fig. 1, inclined tapered rollers 15 are expanded radially of their cage 10 into contact with a tube, held against an adjustable stop 40 on the cage, by axial movement of a tapered mandrel 20 consequent upon its rotation by a head 23, the rollers 15 drawing it forward. The head 23, if not already contacting the cage 10, is then adjusted along the mandrel to contact the cage 10 and is locked thereagainst by a bayonetjointed sleeve 27 to prevent relative axial movement. The rotation of the mandrel is then reversed and the rollers 15 drive the expander back axially along the tube to effect expansion over the required tube length. In another embodiment, Figs. 5, 9, a mandrel 55, secured in an externally-splined plug 57 having a transverse pin 65, slidably engaging a collar 67, guided in longitudinal slots 63, 64 in an internally-splined sleeve 61, is rotated by rotating the sleeve 61, the rollers 15a drawing the mandrel forward to expand them. The mandrel is then held in this axial position relative to the sleeve 61 by an abutment nut 69 threaded on the sleeve, the cage 10a being held against axial movement relative to the sleeve 61 and thus the mandrel 55 by a cap 77. Reverse rotation of the mandrel then withdraws the tube expander, expanding the tube as it moves back. In a further embodiment, Figs. 12, 13 and 15, a mandrel 119 is rotated by a shaft 175 of a motor 177. A roller cage 9 is secured against axial movement relative to a sleeve 145 by a housing 133. The sleeve 145, which is slidable longitudinally relative to an inner sleeve 147 secured to the motor 177, is locked to the sleeve 147, after the rollers have been initially expanded, by axial movement of the mandrel 119, and prior to the reverse rotation of the mandrel, by radially movable ratchet plug members 159, 161 in the sleeve 145 engaging ratchet surfaces 151, 152 on the sleeve 147, relative rotation of 145, 147 engaging or disengaging the ratchet members. The current to the motor may be cut when it reaches a pre-determined value.

Abstract: 1,248,731. Film fibrillation; laminates. SMITH & NEPHEW RESEARCH Ltd. 8 Aug., 1968 [10 Aug., 1967], No. 36340/67. Headings B5B and B5N. [Also in Divisions B2 and D1] An adhesive tape comprises a backing of woven or non-woven fabric made from thin flat polymeric filaments obtained by slitting and drawing polymeric film and an adhesive on at least one surface of the backing. The film preferably comprises polypropylene, but other films may be used e.g. polyamide films or laminated films e.g. polypropylene/polyethylene or polyamide/polyethylene; the filaments from laminated films are preferably bonded one to another e.g. by heat or impulse sealing at cross-over points after the fabric is formed. In a preferred embodiment the filaments are obtained by slitting an extruded film having a thickness of 0À003 inch into ribbons  inch wide which are then drawn under the action of heat under a draw ratio of 8 or 9 to 1 to produce filaments 1/10 inch wide and 1/1000 inch thick. In one drawing method the ribbons pass over a series of godet rollers and then through a heating zone to another series of rollers rotating 8 or 9 times the speed of the first roller. The fabric may be coated on one or both surfaces which may have been pre-treated by a corona discharge with an adhesive e.g. an auto adhesive butyl rubber composition of which several examples are described. The tensile strength of the backing fabric may be increased by giving it an extruded film coating of the same or another polymer, or the fabric may be laminated by means of adhesive to a preformed film of the same or another polymer, thus waterproofing the backing. A reinforced foam tape may be made by laminating the woven fabric to foamed material such as polyurethane, polyvinyl chloride or polyethylene by means of adhesive and spreading a further coating of adhesive thereon. A high strength extensible tape may be made by weaving or knitting the flat polymeric filaments in the form of a tube and cutting the tube on the bias into lengths. The material is preferably laminated by means of adhesive to an extensible film such as plasticized polyvinyl chloride or a copolymer of ethylene/vinyl acetate, and then provided with a further coating of adhesive.

Abstract: 973,040. Rotary offset printing machines; sheet-feed mechanism. COLOR METAL A.G. Oct. 4, 1962 [Oct. 18, 1961], No. 37597/62. Heading B6C. In an endless chain type mechanism for transporting printed sheets from one printing couple to another, positive engagement between each sheet-gripper carrying chain motivated carriage 7, Fig. 1, and the drive of the printing machine-which is directly coupled to the drive of the axles 48, Fig. 5, of chain wheels 8-as the sheets are transferred to or from the transporting mechanism from or to the impression cylinder 3 of the relevant couple is effected through the engagement of rollers 11, 43, Figs. 5, 8, 9, mounted on the carriage, with reversing stirrups 16 provided around the chain wheels. Each stirrup has guideways 57, 58, Fig. 5, the latter having a recessed portion 58a. These guideways respectively engage roller 43 and 11 the recessed portion 58a allowing a period of carriage travel around each wheel 8 during which only the engagement of the roller 43 is effective. This ensures that during the period of sheet transfer action, when the grippers on the carriages and the impression cylinders interact through the usual cam operation, the only drive connection between the machine drive and each carriage is that between wheel mounted support forks 34 and 40, Fig. 5, and respective carriage mounted roller 33 and bolt section 39, Fig. 9. Such connection is effected by the engagement between the guideway 57 and the roller 43 causing the roller 33 and the bolt section 39 to be pressed tightly into the forks 34, 40. The guideway 58 is in effect a continual tion of guide rails 10 provided for carriage guidance between the chain wheels 8 through the interengagement therewith of the rollers 11. The chain drive to each carriage as the latter moves between, the chain wheels 8 is effected by the engagement of a drive roller 64 of a driver member 59, Figs. 8, 9, pivotally mounted on each chain, with a U-shaped link 31 having divergent limbs supported at the associated end of the carriage. This link is disengaged whilst the carriage is passing around each wheel 8 as the roller 64 has moved towards the axle 48 and has consequently come to rest between the limbs of the link 31 where the distance from limb to limb is greater than the diameter of the roller 64. Each carriage 7 is laterally guided through resiliently mounted rollers 47, Fig. 7 (not shown), at each end of the carriage contacting the rails 10. In a modification, Figs. 11, 12, the support fork 40 is replaced by a spring-loaded support arm 86 having a rounded head 85 for engaging a roller 84 mounted on the carriage in lieu of. the bolt section 29. The support fork 34 is replaced by a radially adjustable fork member 70 whilst connection between the carriage and each chain is effected through a resilient strap 75 which replaces the driver member 59, driver roller 64 and link 31.
